Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grain quality determination device having a support, and in particular, aims to reduce the size and improve portability, and to prevent the misuse by using the rotating disc at an angle greater than the repose angle of the grain. The present invention relates to a grain quality determination device having a support.

[0002]

[Prior Art]

 In a grain quality determination device for brown rice, etc., a rotating disc is rotatably supported by being tilted at a predetermined angle in a box-shaped main body, and is provided on the outer periphery of the rotating disc at equal intervals in the circumferential direction. A number of sample collection holes are formed, and a sample supply part is provided on one side of the rotating disc that is on the lower slope, and the sample grains collected on the other side of the rotating disc are on the other side of the slope. A light detection mechanism (sensor unit) is provided to irradiate the sample grains with light when they are transported, and to detect diffuse transmitted light and diffuse reflected light. Each grain is detected according to the light state detected by the light detection mechanism. The quality of is judged.

The reason for inclining the rotating disc to a predetermined angle that is equal to or greater than the repose angle of the grain is to let the grain into the sample collection hole for each grain put into the sample supply unit at the lower inclined portion of the rotating disc. Therefore, if the rotating disc is not tilted, or if the rotating disc is not tilted more than the repose angle of the grain, the grains that are not in the sampling holes will also be on the surface of the rotating disc. This is because they are transported and transferred, and it is not possible to transfer each grain and supply it to the light detection mechanism (sensor unit).

Such grain quality determination devices are disclosed, for example, in Japanese Utility Model Publication No. 58-71018 and Japanese Utility Model Publication No. 63-103784. The quality judgment devices in these publications are mainly used for guidance on proper cutting time and drying adjustment at collection points such as agricultural cooperatives, and also for voluntary inspections.

[0005]

By the way, in the quality judging device, the device itself has a certain size and weight and is installed and used at a predetermined place. For example, farmers and the like bring sample samples to the location where quality assessment equipment is installed to determine the quality of grains. For this reason, it was not possible to judge the quality of the grain by selecting a place where the quality judging device is easy to use.

However, in order to improve the quality of grain, it is not effective unless each farmer has a quality awareness and the system used by the farmer for quality improvement is easy to use.

Therefore, there is a demand for a quality determination device that is compact, has good portability, can be carried around, and that allows a farmer or the like to freely select a location for determination.

However, when considering the miniaturization of the quality judgment device, in order to incline the rotating disc at a predetermined angle in the main body in order to ensure the repose angle of the sample or more, the rotation disc is rotated in the main body. There is a disadvantage that it is difficult to carry out miniaturization due to a triangular dead space on the back side of the disk, and it is inconvenient to carry and storage is also difficult.

[0009]

[Means for Solving the Problems]

 Therefore, in order to eliminate the above-mentioned inconvenience, the present invention firstly rotatably supports and installs a rotating disk in a housing body, and equidistantly in the circumferential direction on the outer peripheral portion of the rotating disk. When a plurality of sample collection holes are formed in one side of the rotary disc and a sample supply unit is provided on one side of the rotary disc, and the sample grains collected in the sample collection hole are transferred to the other side of the rotary disc. Is equipped with a light detection mechanism that irradiates the sample grains with light and detects diffuse transmitted light and diffuse reflected light, and the quality of each grain is determined by the light state detected by this light detection mechanism. In the quality determination device, when the quality of the grain is determined, the sample supply unit is set to the lower side and the light detection mechanism is set to the upper side to incline the rotating disc to a predetermined angle equal to or greater than the repose angle of the grain. It is characterized in that a support for supporting the main body is rotatably provided on the main body.

Secondly, a rotating disc is rotatably supported and provided in a housing body, and a plurality of sampling holes are formed in the outer peripheral portion of the rotating disc at equal intervals in the circumferential direction. A sample supply unit is provided on one side of the rotating disc, and when the sample grains collected in the sampling hole are transferred to the other side of the rotating disc, the sample grains are irradiated with light and diffused. An optical detection mechanism that detects transmitted light and diffuse reflection light is provided, and the quality of the grain is judged by the grain quality judgment device that judges the quality of the grain for each grain based on the light state detected by this light detection mechanism. At this time, the support for supporting the main body is rotated to the main body so that the sample supply unit is set downward and the light detection mechanism is set upward to incline the rotary disc at a predetermined angle equal to or larger than the repose angle of the grain. Movably provided to detect that the rotating disc is set to the predetermined angle. An angle detection unit for inputting a detection signal is provided to the control unit, and a warning unit is provided to warn when the rotating disk is less than the predetermined angle by being activated by the control unit.

[0011]

[Action]

 According to the structure of the present invention, first, when judging the quality of the grain, the support is rotated to incline the main body, and the rotating disc is inclined to a predetermined angle equal to or greater than the repose angle of the grain. Can be used. This eliminates the need to incline the rotating disk in the housing, eliminates dead space in the body, and enables size reduction. It is easy, and it is compact and easy to store.

Secondly, when judging the quality of the grain, the control unit warns when the support is rotated to tilt the main body, and the rotating disc is not at the repose angle of the grain. Since the alarm is activated by activating the parts, it is promptly notified that the rotating disc is not at the specified angle.After that, the main body is tilted so that the rotating disc is at the specified angle, and the user misuses it. Can be prevented.

The light detection mechanism 8 is supported by the frame base 16 by fixing the fixing portion 34 of the mechanism holder 32 to the end base portion 20 of the frame base 16.

The light detection mechanism 8 is formed with a passage groove 36 that allows the outer peripheral portion 6 a of the rotating disc 6 to pass therethrough.

A transparent auxiliary body 38 is fixed to the end base portion 20 and is located below the outer peripheral portion 6 a of the rotary disc 6 and parallel to the rotary disc 6.

Although not shown, the light detection mechanism 8 is provided with a light source that irradiates light and each detection unit that detects the respective amounts of diffuse transmitted light and diffuse reflected light.

Further, on the lower surface of the bottom plate 10, one side base leg 40-1 is fixed to one side and the other side base leg 40-2 is fixed to the other side.

The one-side base leg 40-1 is provided with an inclined mounting notch surface 42 that comes into surface contact with the mounting surface G 1 when the main body 4 is inclined at a predetermined angle θ described later.

A support 44 is rotatably provided on the side plates 12 and 12 of the main body 4 on the side of the light detection mechanism 8. The support 44 includes main members 46, 46 located on the outer side surfaces of the side plates 12, 12, and a connecting member 48 for connecting the main members 46, 46. One end sides of the main members 46, 46 are provided on a support shaft 50 directed to the width direction of the main body 4 and supported by the side plates 12, 12. The other ends of the main members 46, 46 are connected by a connecting member 48.

The connecting member 48 has a support member bottom surface 52 that is oriented substantially at right angles to the axes of the main members 46, 46.

As shown in FIG. 2, the support body 44 is rotated about the support shaft 50 and placed on the placement surface G, and the main body 4 is tilted so that the rotary disk 6 is placed at a repose angle of grain or more. Incline to a predetermined angle θ.

Further, the one side plate 12 is provided with an angle detector 54 as shown in FIG. As shown in FIG. 3, the angle detector 14 has a micro switch 56, and is closed when the main member 46 of the support body 44 does not reach the micro switch 56, but the main member 46 is a micro switch. When the switch 56 is reached, it has the function of closing and the rotation of the support body 44. The angle detecting mechanism 54 is held by a mounting body 58. The mounting body 58 is fixed to the side plate 12 by mounting screws 60, 60.

Further, as shown in FIG. 5, the quality judging device 2 is provided with a starting signal generating part 62 for generating a starting signal when the quality judging device 2 is started. The angle detector 54 is connected to the controller 66 via the NAND circuit 64. A first resistor 68 is interposed between the angle detector 54 and the NAND circuit 64, and a second resistor 70 is interposed between the activation signal generator 62 and the NAND circuit 64. The NAND circuit 64 is a part of the controller 66.

A judgment circuit 72 is built in the control unit 66. The determination circuit 72 is connected to the light detection mechanism 8 and performs grain quality determination for each grain according to the state of the amount of each of the diffuse transmitted light and the diffuse reflected light which are the detected light states.

A warning unit 76 is connected between the NAND circuit 64 and the control unit 66 via a knot circuit 74.

The warning unit 76 is activated by the control unit 66 to generate a warning when the micro switch 56 of the angle detection unit 54 is closed and the activation signal generation unit 62 is generating a signal. is there.

Next, the operation of this embodiment will be described.

When judging the quality of the grain, as shown in FIG. 2, the support body 44 is rotated toward the bottom plate 10 side of the main body 4, the main body 4 is tilted, and the rotary disc 6 is rotated by a predetermined angle θ. Then, the inclined mounting notch surface 42 of the one-side base leg 40-1 is brought into contact with the mounting surface G and the bottom surface 52 of the connector is brought into contact with the mounting surface G.

Then, when the quality determination device 2 is activated, the activation signal generator 62 generates a signal.

By the way, when the rotary disc 6 is less than the predetermined angle θ, the micro switch 56 is closed and there is no signal from the angle detection unit 54, the control unit 66 activates the warning unit 76 to rotate the rotary disc 6. Warning that 6 is not the predetermined angle θ. As a result, when the user further rotates the support body 44 and tilts the rotary disc 6 at a predetermined angle θ that is equal to or greater than the repose angle of the grain, the angle detection unit 54 opens (see FIG. 3). ), The control unit 66 stops the operation of the warning unit 76 by both signals from the angle detection unit 54 and the activation signal generation unit 62.

Then, when the grains are supplied to the sample supply unit 22 and the drive motor 28 is driven to rotate the rotary disc 6, the grains are collected in the sample collection holes 30 one by one, and the light detection mechanism 8 is used. Therefore, the light state of each grain is input to the determination circuit 72, and this determination circuit 72 determines the quality of the grain.

When the quality judgment is completed and the quality judgment device 2 is stored, the support 44 is rotated upward to position the support 44 at the upper portion as shown in FIG. The support 44 does not get in the way, and can be stored compactly.

As a result, since it is not necessary to incline the rotary disc 6 from the beginning in the main body 4, the rotary disc 6 can be positioned substantially parallel to the bottom plate 10, and the rotary disc 6 can be positioned in the main body 4. It is possible to avoid the occurrence of a dead space having a triangular shape on the back surface of 6 and to downsize the quality determination device 2.

Further, when the quality discriminating apparatus 2 is used, if the rotating disc 6 is less than the predetermined angle θ, the warning unit 76 warns that the rotation angle is not the predetermined angle θ. It can be used by being positioned at the angle θ, and it is possible to prevent misuse by the user.

Further, when the quality determination device 2 is carried, the support body 44 can be rotated and the support body 44 can be used as a grip, thus improving portability.

In this embodiment, the rotation disc 6 is not set to the predetermined angle θ by inputting the signals of the activation signal generator 62 and the angle detector 54 to the controller 66 via the NAND circuit 64. In this state, the warning is generated only when the activation signal is generated. However, the signal of the angle detection unit 54 is directly input to the control unit 66 to generate the warning regardless of the presence or absence of the activation signal. Is also good.

Further, although the warning unit 76 is a buzzer in the embodiment, other warning means, for example, display output, print output, voice output, etc. may be used, and further, the device is not activated. It is included in the occurrence of warnings.
