Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sample paddy (fir) at a rice center (rice and wheat joint drying preparation facility) and the like.
The present invention relates to a drying device.

[0002]

2. Description of the Related Art In recent rice centers, participating farmers are provided with a farmer's card with a farmer's code and a receiving hopper in order to streamline the work of bringing in concentrated harvested paddy temporarily. The operation from the machine to the roughing machine, automatic moisture meter, weighing machine, receiving tank (product type / moisture etc.) is mechanically automated, its control, various data and product types obtained during the flow In addition, computer processing of storing and processing farm card data, printing on slips, and the like is performed intensively by a computer. By this, the efficiency of office work and work is achieved, but for the paddy rice to be brought in, this is converted into final moisture, for example, the weight of sized brown rice of around 14.5%, and the incoming and outgoing share of each farmer is It has been calculated.

[0003] In order to calculate the equity of each farmer, the operator collects a sample from the paddy rice brought in and also dries it to a predetermined moisture content by a sample pad dryer (test dryer). That is, as shown in Japanese Patent Publication No. H8-33276 (see FIG. 8), a large number of dry boxes, each of which is suspended on an endless chain rotated by a motor and containing a sample, are placed at predetermined intervals along the endless chain. After drying for a predetermined period of time by a plurality of drying units provided at the positions, the endless chains rotate and refining is performed, and the next drying box is dried in the drying unit. Then, a sample paddy drying apparatus is known in which a dried sample paddle is discharged by a sample discharger when the moisture sampler detects that the dried paddy pad has a predetermined moisture content.

[0004] However, in the sample paddy drying apparatus, the drying unit is dispersedly arranged in the machine frame (see FIG. 8), and the air passage is congestedly arranged (not shown), so that maintenance is troublesome. I was Therefore, Tokuhei 7-11
As shown in Japanese Patent No. 7338 (see FIG. 9), there is known a sample paddy drying apparatus in which a plurality of drying units are provided along the endless chain and arranged intensively and continuously. Further, in the sample paddy drying device, the drying unit is arranged continuously in a concentrated manner, and forms an endless chain that is rotated by a pair of pulleys provided at the upper and lower portions. Dry box and 6
A drying section was provided at a location, and the height was about 6 meters. In order to install the sample paddy drying apparatus, the ceiling of the building had to be restricted or remodeled.

[0005]

By the way, in the sample paddy drying apparatus, since the drying units are continuously arranged, the endless chain is rotated by several units of the plurality of drying units, and all of the endless chains are rotated at one time. The total number of the drying boxes is set to be a multiple of the total number of the drying sections in order to dry the drying section completely. Therefore, each of the drying boxes is dried once and then returned to the drying section, so that it is always dried in the same drying section as before.

On the other hand, the drying conditions of the drying section are controlled by a control device for controlling a predetermined temperature setting of the drying section and a temperature sensor provided in the drying section. It is the present condition that the drying conditions slightly vary with respect to the setting (the heat generation temperature of the heat generation unit of the drying unit 13 and the air blowing amount of the blower). Therefore, as described above, since each drying box is dried many times in the same drying section, after a lapse of a certain time, the dried paddy in each drying box after the drying is finished has a variation in drying. In order to eliminate these variations, a more accurate temperature and moisture detection sensor
It is possible by mounting a control device and the like, but if this is mounted, the cost will increase accordingly.

[0007] In view of the above, the present invention does not require the above-described high-precision precision temperature sensor or temperature control device to be mounted on each of the drying sections, and the finish moisture of a plurality of drying boxes B containing sample paddy is not required. It is a technical object to provide the sample paddy drying device that can reduce the variation in the value more favorably.

[0008]

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the drawings.

[0011] The sample paddy drying apparatus 1 comprises a substantially airtight body 2
And a pair of endless chains 3 are rotatably extended inside the body 2 so as to overlap with each other. The endless chain 3 includes chain gears 4, 5 provided at both upper corners in the body 2.
And a substantially concave rotation trajectory is drawn by being regulated by regulating plates 19 provided at both corners and the center of the lower part of the body 2. In addition, the sample paddy drying device 1
Chain gear 8 connected to an electric motor 10 provided in the upper center
The chain gears 6 and 9 connected to the chain gears 4 and 5 are linked by an endless chain 21 via a chain gear 7. Therefore, the power of the electric motor 10 is transmitted to the chain gears 4 and 5, so that the endless chain is rotated.

A plurality of drying units 13 composed of a heat generating unit 11 and a blower 12 are arranged at predetermined intervals in the vertical direction at a position along the endless chain 3 on a side portion inside the body 2. A plurality of drying boxes B are fixedly disposed on the endless chain 3 in a fixed direction at intervals of installation of the respective drying units 13. The drying box B has a ventilation part 18c on a side surface facing the drying part 13, an opening / closing lid 18 integrally provided with a rotatable opening / closing piece 18a, and urging means 18b for urging the opening / closing lid. And a gas-permeable bottom portion 17 provided at a position facing the opening / closing lid 18 in the inside thereof. In addition, the sample paddy drying apparatus 1 includes guide plates 14a and 14b provided on the side of the drying unit 13 along the rotation locus of the endless chain 3 for guiding the drying box B; A sample supply unit 16 on one side, a sample discharging device 15 and a sample discharging port 20 on the other side, and a valley of a substantially concave rotation locus of the endless chain 3 substantially at the center of the body 2. The control box 25 is disposed at the position.

The control box 25 is, as shown in FIG.
It is composed of a CPU (Central Processing Unit), a storage device composed of ROM and RAM, an interface, etc., and inputs the drying conditions calculated by the host computer 22, and controls the drying unit 13 and the drying box movement. These are electrically connected to the circuit 23 and the sample paddy discharging device 15 so as to output signals to them.

The step of putting paddy into the drying box B will be described. When the drying box B approaches the drying section 13, the opening / closing lid 18 is opened by bringing the opening / closing piece 18a into contact with the guide plates 14a, 14b. In the drying box B in which the opening / closing lid 18 is opened in front of the guide plates 14a and 14b, the paddy supplied from the input port 16a of the sample supply unit 16 is supplied by a fixed amount at a time. Charged through the passage 16b and the supply port 16c. When the paddy is put into one drying box B, the proximity sensor (not shown) provided near the supply port 16c senses the passage of the sample paddy, and the electric motor 10 controls the control box.
According to the instruction of 25, the endless chain 3 is rotated upward by one drying box. In this manner, the input is completed by repeatedly inputting the paddy into each of the drying boxes B.

Next, the drying step of the drying box B will be described. Each of the drying sections 13 includes a blower 12 and a heating section 11, and the blower 12 and the heating section 11 are configured so that power can be turned on / off by the control box 25. A drying box B in which the opening / closing lid 18 is opened by being regulated by the guide plates 14a and 14b is located near each of the plurality of drying sections 13 provided in the vertical direction. In the drying box B, hot air flows from the air inlet 120a of the drying section 13 through the ventilation section 140 provided in the guide plate 14a,
Further, the hot air was supplied through the ventilation part 18c of the drying box B, and the hot air passed through the air permeable bottom part 17 in the drying box B and contacted the sample paddy A, and then the opening / closing lid 18 was opened. Dry box B
Will be discharged from the opening. In this step, after each drying box B is simultaneously dried by hot air for a predetermined time,
At this time, all of the plurality of dried boxes B which are located on the side of the drying section and are dried are simultaneously moved to a position away from the drying section, and the next undried box B is also moved at the same time and the drying section 13 is moved. Will be close to. The drying condition of each drying box B is calculated by the host computer 22 which controls and manages each section of the rice center, and is sent to the control box 25 to be set. After the drying box B is dried under the predetermined drying conditions, the power of the drying unit 13 is turned off by the CPU control of the control box 25, the supply of the hot air to the drying box B is stopped, and the other drying boxes B are dried. Similarly, this drying step is repeated until all the drying is completed.

Next, the refining process of the sample paddy A will be described. Each of the drying boxes B dried in the drying step is separated from the drying unit 13 by the rotation of the endless chain 3 by the electric motor 10, and the equilibration (tempering) of the moisture between the sample paddy A itself and each paddle proceeds. , To prepare for the next drying action. The dried sample paddy A in the drying box B passes through each of the drying boxes B while passing through the substantially concave rotation trajectory of the endless chain 3.
Will be well mixed within. In other words, the traveling direction of the drying box B is reversed twice during up and down and left and right once during one round of the substantially concave rotation trajectory, and the sample paddy in the drying box B is agitated a plurality of times. become.

Next, the step of discharging the sample paddy will be described. After the drying step is completed, the output signal of the control box 25 causes the electric motor (not shown) to rotate the rotating shaft 15a to operate the link mechanism 15b, and then the cam 15c is rotated by the link action. The cam 15c is an open / close piece of the open / close lid 18.
The opening / closing lid 18 is opened by contacting the opening 18a. At this time, the discharge gutter 15d is also rotated by the rotation of the opening / closing shaft 15a, and the falling sample paddy A is discharged from the discharge port 20 through the discharge gutter 15d. And the sample paddy A of all the dry boxes B will be discharged.

Next, the operation of the above embodiment will be described (see FIG. 1). In this embodiment, the number of the drying boxes B is 41, and four drying units 13 are provided continuously.
Drying box B is formed so as to move in units of four and to move every six minutes.

Now, from a rice paddy rice paddy rice brought in by a certain farmer, for example, when 1 kg of a sample is put into the input port 16a of the sample supply section 16, the paddy rice passes through the rice supply path 16a from the supply port 16c into the drying box B5. It is thrown into. Prior to this,
The weight of the paddy rice and the moisture content of the rice paddy of the farmer's instep are measured by a so-called automatic receiving device, and the data is input to the host computer together with the farmer's code. It is. The received weight, the moisture content and the variety data and the drying conditions calculated by the host computer 22 are transmitted by communication means and stored in the storage device of the control box 25 for each farmer code. The sample of the paddy rice brought in in this way is sequentially put into the drying box B and dried according to the stored condition of the paddy rice.

When the input of the sample paddy A into (all) the drying box B is completed, this is detected by a sample pad presence / absence detection sensor (not shown) or the like, and a signal thereof is input to the control box 25, and Each heating section 11a, 11b, 11c, 11d generates heat by an output signal from the control box 25 in accordance with the drying condition, and each air blower 12a, 12b, 12c, 12d is activated to activate each drying box.
Hot air at, for example, about 45 ° C. is blown to the sample paddy A in B1, B2, B3, and B4.

In this way, when the drying of each of the drying sections 13a, 13b, 13c, 13d is completed for 6 minutes, the motor 10 moves the respective drying boxes B1, B2, B3, B4 according to a command from the control box 25, and at the same time, moves on to the next. The drying boxes B5, B6, B7, B8 are moved for a predetermined time until the drying boxes B5, B6, B7, B8 are moved to the positions of the drying units 13a, 13b, 13c, 13d.

The sample paddy A once passed through the drying unit 13 is:
Next, for about 60 minutes before receiving the drying action, the moisture equalization (tempering) proceeds between the sample rice grains themselves and each rice grain without being subjected to the drying action, so that the next drying is prepared.

The drying conditions of each drying box B are set by being sent to the control box 25 from a host computer 22 for controlling and managing each section such as a rice center. This is repeated until all the drying boxes B have been dried.

When the predetermined drying conditions are completed, the power of the drying unit 13 is turned off by the control box 25 and the drying box B
The supply of hot air to is stopped. Thereafter, the output signal of the control box 25 activates the sample discharging device 15 to discharge the sample paddies A of all the drying boxes B, and is conveyed to a test hulling screening machine (not shown) or the like.

[0025]

Next, each drying box B and four drying units 13a, 13b,
A description will be given of the positional relationship between the circles 13c and 13d.
In the present invention, since the total number (P) of the drying boxes is set to a number different from a multiple of the total number (H) of the drying sections, the total number (P) is expressed by an expression of P ≠ nH (n is a natural number). When the total number (H) is four and n = 10, the total number (P) of the dry boxes B can be set to 42 in order to set the total number (P) of the dry boxes not satisfying nH = 40. At this time, the drying box B1 is located at the position of the drying unit 13a in the first lap, and the drying box B1 is located at the position of the drying unit 13c in the second lap. like,
Each time it goes around, it shifts by one, and after the third lap, the above 1
One skip is repeated as in the second and third laps (see FIG. 3). Therefore, the sample paddy A in each drying box B is not continuously dried in the same drying unit 13 and,
Even if the 13 drying conditions vary, the drying section changes for each drying, so that the drying action on one drying box is balanced.

As an example in which the total number (P) of the drying boxes B is an odd number, when the number of the drying sections 13 is four and n = 10, the total number of the drying boxes B can be set to 43. In the first lap, the drying box B1 is located at the position of the drying unit 13a in the first lap (the first lap is the time of the first drying). On the lap, the drying box B1 is shifted to the position of the drying section 13c. On the fourth lap, the drying box B1 is shifted to the position of the drying section 13b. It is repeated in the same manner as the drying of the fourth round from the eyes (see FIG. 4). Therefore, the sample paddy A in each drying box B is not continuously dried in the same drying unit 13, and even if the drying conditions of each drying unit 13 vary, the drying unit 13 is turned around. Since the drying sections 13 are changed one by one, all the drying sections 13 are evenly dried, and the drying action is further balanced than in the previous embodiment.

Next, if the total number (P) of the drying boxes B is set to be one more than the number n times the total number of drying sections (H), P = n
H + 1 (n is a natural number), and as an example,
When the number of drying units 13 is 4 and n = 10, the total number of drying boxes B
In this case, the positional relationship is as follows. In the first lap, the drying box B1 is located at the position of the drying unit 13a, (the first lap is the time of the first drying). B1 is at the position of the drying unit 13b, on the third lap, the drying box B1 is at the position of the drying unit 13c, and on the fourth lap, the drying box B1 is at the position of the drying unit 13d. It will shift. The fifth and subsequent laps are repeated in the same manner as the drying of the first to fourth laps (see FIG. 5). Accordingly, since the drying units 13 are changed one by one in the same manner as described above, all the drying units 13 are dried, and the drying action is balanced.

Next, when the total number (P) of the drying boxes B is set to a number one less than the number n times the total number of drying sections (H), P =
n H-1 (n is a natural number), for example, assuming that four drying units 13 and n = 10, the total number of drying boxes B can be set to 39. In this case, In the first rotation, the drying box B4 is located at the position of the drying unit 13d in the first lap, and (1)
In the second lap, the drying box B4 is in the position of the drying section 13c in the second lap, and in the third lap, the drying box B4 is in the position of the drying section 13b, and in the fourth lap, the drying box B4 is in the drying section. The position of 13a is sequentially shifted by one each time the vehicle goes around as shown in Fig. 6, and the fifth and subsequent weeks are repeated in the same manner as the first to fourth laps (see Fig. 6). Accordingly, since the drying units 13 are changed one by one in the same manner as described above, all the drying units 13 are dried, and the drying action is balanced.

In the above description, the total number (H) of the drying units 13 is fixed (four), but the positional relationship between each drying box B and the drying unit 13 when the total number (H) is five (not shown). Assuming that the number of dry boxes is 52 as an example of P ≠ nH, the number of dry boxes is skipped by one every round, and after the sixth lap, the drying is repeated in the same manner as the first to fifth laps. Assuming that the total number (P) of B is an odd number, for example, if the number of dry boxes is 53, the number of B is shifted by 3 each time the circuit goes around, and 1 after the 6th lap.
Repeated in the same way as the drying from the lap to the fifth lap, P = n
Assuming that the number of dry boxes is 51 as an example of H + 1, the number of drying boxes is sequentially shifted by one each time the circuit is rotated, and the sixth and subsequent laps are repeated in the same manner as the first to fifth laps, and P = n H-1 Assuming that the number of dry boxes is 49, the number of dry boxes is sequentially shifted by one each time the circuit rotates, and the sixth and subsequent laps are repeated in the same manner as the first to fifth laps.

In the above embodiment, the number of the drying boxes B is changed so that the drying box B is not dried in the same drying section every time the circuit goes around. This can be achieved by providing a drying box movement control circuit 23 for controlling the electric motor 10 so that the drying box B is dried in a drying section different from the previous drying section when the drying box returns to the drying section again. Not shown).

[0031]

As described above, according to the sample grain drying apparatus of the present invention, in order to reduce the variation in the finish moisture value of the plurality of drying boxes containing the sample paddy, it is preferable to reduce the variation.
It is not necessary to newly provide a high-precision precision temperature sensor or the like for controlling the temperature of the drying section. In addition, since the drying is not continuously performed in the same drying unit every time the drying box rotates, the variation in the dry state (moisture content) of the sample paddy in each drying box can be reduced and improved. That is, the total number (P) of the drying boxes of the present invention is set to a number different from a multiple of the total number (H) of the drying sections, the total number of the drying boxes is odd, or the total number of the drying boxes is To set the number to be increased or decreased by one from the multiple of the total number, simply set the total number of the drying boxes as described above. Therefore, similarly, a new drying box movement control circuit is provided in the control box of the present invention. This is a means that can be implemented more quickly. In addition, by making the rotation locus of the endless chain substantially concave, stirring of the sample paddy in each drying box fixed to the endless chain is sufficiently performed, so that tempering of the sample paddle is also performed. It will be performed well. Accordingly, the dried state (moisture content) of the sample paddy in each of the dried boxes after drying is less scattered and better than before. Furthermore, the sample grain drying device of the present invention is downsized by making the rotation locus of the endless chain 3 substantially concave,
There is an effect that it is not necessary to restrict or remodel the ceiling of the building for installing the sample paddy drying device which is configured vertically as in the related art.
