Description

[Detailed description of the invention] Industrial application field The present invention can detect large grains (such as soybeans, barley, etc.) with smooth surfaces and hard surfaces between a pair of main and sub-moisture detection rolls installed opposite each other. It is possible to accurately supply and crush the material and quickly detect moisture.
This invention relates to a moisture measuring device for soybeans, barley, etc., which can prevent large grains from being caught between the left and right side walls of a storage chamber and the right and left sides of a sub-moisture detection roll and not being able to be removed.

Conventional technology Conventionally, the paddy during circulation drying is accurately collected without being manually removed, and the paddy is crushed by a pair of moisture detection rolls, thereby automatically measuring the moisture content of the paddy and ensuring accurate drying. An automatic moisture measuring device for dried rice grains that can be operated is known and was described in Japanese Patent Publication No. 16305/1983 before the present application.
The contents will be explained using FIG. That is,
There are crushing rolls 2, 2 that crush a certain amount of supplied paddy during the circulation drying process, and below the crushing rolls 2, 2 there is a pair of moisture detectors that detect resistance changes due to water content by pinching the crushed paddy. The rolls 3, 3 are arranged, and the moisture detection rolls 3, 3 and the electric resistance meter 4 are connected via a lead wire 5, and 1 is connected to the crushing rolls 2, 2 and the moisture detection roll 3. , 3, 6 is a circulation elevator, 7 is a charging gutter whose base end is connected to the elevator 6, and whose tip end is connected to the dryer main body (not shown), 8
is a switching valve for opening/closing a supply window 9 opened at an appropriate position in the input gutter 7; the upper end side of the main body 1 is connected to the supply window 9; The structure is such that the water content of the paddy can be automatically measured by supplying a portion of the paddy to the crushing rolls 2, 2 at any time.

Problems to be Solved by the Invention By the way, conventional automatic moisture measuring devices of this type were designed for rough, soft, and small-grained paddy and wheat, so the supplied paddy and wheat could stagnate. It is smoothly fed between a pair of crushing rolls and crushed without any friction.

However, when measuring the moisture content of large grains with smooth and hard surfaces, such as soybeans and barley, using a conventional automatic moisture measuring device, the large grains roll on a pair of crushing rolls, causing the particles to fall between the crushing rolls. The moisture measurement work for large particles cannot be carried out smoothly, and the large particles are caught between the left and right side walls of the storage chamber and the left and right sides of the main and sub-moisture detection rolls, requiring more power than necessary. Needless to say, problems such as a significant decrease in the crushing efficiency of large particles occurred.

Means for Solving the Problems The present invention solves the above-mentioned problems, and the details thereof will be explained below using FIGS. 1 and 2, which correspond to embodiments. That is, a pair of main moisture detection rolls 10 are placed in a storage chamber 102 that has an input port 105 at the top and a discharge port 106 at the bottom.
3 and an auxiliary moisture detection roll 104 whose width and length are shorter than the main moisture detection roll 103 are rotatably installed opposite each other with a crushing gap in between. On both left and right sides of the main moisture detection roll 103, pressing movable bodies are disposed on the upper part of the main moisture detection roll 103 so that the entire body is always resiliently directed downward with the spring portion 108 provided on the base end side as an axis. A regulating boss 109 that regulates the lower limit position of the pressing movable body 107 and a plurality of push-up pins 110 that push up and rotate the pressing movable body 107 to the upper limit position about the spring part 108 are provided concentrically. A pressing roller 111 facing the crushing gap is freely rotatably mounted on the tip side of the pressing movable body 107, and the pressing movable body 107 is connected to a spring portion 108 for the rotational operation of the main moisture detection roll 103 and the spring part 108. It is reciprocated up and down as a shaft, and the press roller 111 actively pushes large grains into the crushing gap, allowing the pair of main and auxiliary moisture detection rolls 103 and 104 to more accurately accomplish the crushing work, as well as the auxiliary moisture detection roll. There are storage chambers 102 on both the left and right sides of 104.
A cam-shaped cleaning body 112 is integrally attached between the left and right side walls 102a, 102b of the sub-moisture detection roll 104 and the left and right sides 104a, 104b of the sub-moisture detection roll 104, which can forcibly scrape out large particles. be.

Operation Now, the main moisture detection roll 103 and the sub-moisture detection roll 104 are rotated in the direction of the arrow, respectively, and large grains (for example, soybeans, barley, etc.) for measurement are supplied into the storage chamber 102 during circulating flow. . Then, the pressing movable body 107 whose lower limit position was regulated by the regulating bosses 109 protruding from the left and right sides of the main moisture detecting roll 103 will move to the main moisture detecting roll 1.
The push-up pin 110 rotates concentrically in response to the rotational movement of the pin 03, overcomes the spring force and is forcibly pushed up to the upper limit position, and then descends until it collides with the regulation boss 109 due to the spring force. be done.

Therefore, when the main moisture detection roll 103 rotates, the pressing movable body 107 moves the main moisture detection roll 103.
The pressing movable body 107 is reciprocated up and down about the spring part 108 in the upper storage chamber 102.
The pressing roller 111, which is suspended loosely at the tip side of the pressing movable body 107, is also reciprocated up and down toward the crushing gap for the purpose of elasticity of the pressing movable body 107. As a result, the large grains supplied into the storage chamber 102 are forcibly pressed toward the crushing gap by the resilient pressing action caused by the up and down reciprocating movement of the pressing roller 111, so that the large grains are transferred to the pair of main and auxiliary moisture detection rolls 103. , 104, and are pushed into the crushing gap each time the pressing movable body 107 reciprocates up and down, and are accurately crushed. At the same time, the moisture value of the large particles is detected by the main and sub-moisture detection rolls 103 and 104. is detected accurately.

By the way, during the moisture value detection work as described above, some of the large grains rolling on the main and sub-moisture detection rolls 103 and 104 hit both the left and right sides of the main and sub-moisture detection rolls 103 and 104 and the storage chamber 102. It may fall into the gap between the left and right side walls 102a, 102b together with dust, get caught and accumulate, and become impossible to take out. However, even in the above state, in the present invention, the sub moisture detection roll 104 is formed to have a width shorter than the main moisture detection roll 103, and the left and right side walls 102a of the storage chamber 102, 102b and the left and right side surfaces 104a and 104b of the sub-moisture detection roll 104
Since a large gap is formed between the rollers 104 and 104, the large particles that are rolling are allowed to fall into this gap. Since the large particles are configured to be actively scraped out by the cleaning body 112, the large particles remain trapped in the gap and accumulate, allowing the large moisture detection work to be carried out smoothly without requiring more power than necessary. It can be done efficiently. Moreover, the sub-moisture detection roll 104
Since the outer circumferential surface of the cleaning body 112 is in sliding contact with the cleaning brush 113, the outer circumferential surfaces of the sub-moisture detection roll 104 and the cleaning body 112 are always maintained in a clean state, and the crushing and scraping operations of large particles can be performed accurately. be able to.

The moisture measuring device 10 is a moisture measuring device disposed at an appropriate position during the circulating drying process of a drying device (not shown) capable of circulating drying grains such as pigeon wheat, etc.
1 is configured as follows. That is, a pair of main moisture detection rolls 103 and a sub-moisture detection roll whose width and length are shorter than the main moisture detection rolls 103 are installed in a storage chamber 102 having an input port 105 at the top and a discharge port 106 at the bottom. The roll 104 is housed in the shaft rack so as to be rotated in the direction of the arrow with a crushing gap in between. On both left and right sides of the main moisture detection roll 103, spring portions 10 are formed entirely of elastic rods into a rectangular frame shape and provided on the base end side.
A regulating boss 109 is configured to receive the pressing movable body 107 disposed in the accommodation chamber 102 above the main moisture detection roll 103 so as to be constantly projected downward with the axis 8 as an axis, and to regulate its lower limit position. and a plurality of push-up pins 110 for pushing up and rotating the pushing movable body 107 to the upper limit position about the spring portion 108 by overcoming the elastic force are concentrically protruded. A pressing roller 111 facing the crushing gap is rotatably suspended on the tip side of the pressing movable body 107 formed in the shape of a rectangular frame as described above.

Allows moisture level to be detected.

112 are left and right side walls 102a of the storage chamber 102,
102b and left and right side surfaces 1 of the sub-moisture detection roll 104
04a and 104b, the cleaning body 112 is a cleaning body for actively scraping downward large particles that have fallen into the gap formed between the cleaning body 112 and the cleaning body 112. It is configured to be integrally attached to the left and right side surfaces of the moisture detection roll 104 and rotated together with the auxiliary moisture detection roll 104. Reference numeral 113 is a cleaning brush disposed at a position opposite to the lower part of the sub-moisture detection roll 104, and in order to enable the cleaning brush 113 to come into sliding contact with the outer peripheral surfaces of the sub-moisture detection roll 104 and the cleaning body 112,
The cross-sectional shape is formed into a concave shape so that the outer peripheral surfaces of the sub-moisture detection roll 104 and the cleaning body 112 are always maintained in a cleaned state.

Note that the cam-shaped cleaning body 112 closes in the storage chamber 1 when the pressing roller 111 is at the lower limit position.
A large gap is opened between the left and right side walls 102a, 102b of 02 and the left and right sides 104a, 104b of the sub-moisture detection roll 104, so that a part of the rolling large grains escapes to the sub-moisture detection roll 104 side as much as possible. Furthermore, when the pressing roller 111 is at the upper limit position, it is most effective to set the gap so that the large particles that have fallen can be scraped out downward by the rotating cleaning element 112.

Effects of the invention In short, the present invention has the above-mentioned specific configuration, so even when detecting the moisture content of large grains such as soybeans and pearl barley that have smooth and hard surfaces, it is possible to The large grains housed in the moisture detection roll 102 are rotated by the main moisture detection roll 103 and the spring part 108
Due to the pressing action of the pressing movable body 107, which can be reciprocated up and down due to the downward springing force, and the pressing roller 111, which can be reciprocated up and down, it is forced to move on the pair of main and sub-moisture detection rolls 103 and 104 without rolling. The pressing movable body 107 has a regulating action of a regulating boss 109 protruding from the main moisture detecting roll 103, which allows the moisture value of large particles to be quickly detected by supplying the particles into the crushing gap and crushing them. Due to the pushing up action by the pushing up pin 110,
A significant saving in power is achieved by automatically reciprocating up and down within the range between the lower limit position and the upper limit position without using any other power by simply rotating the main moisture detection roll 103 and snapping the pressing movable body 8. In addition, the width of the sub-moisture detection roll 104 is made shorter than that of the main moisture-detection roll 103, and the left and right side walls 102a, 102b of the storage chamber 102 are provided on both the left and right sides of the sub-moisture detection roll 104.
