Description

[Detailed description of the invention] "Industrial application field" This invention can detect large grains (such as soybeans, pigeon wheat, etc.) with smooth surfaces and hard surfaces between a pair of main and sub-moisture detection rolls installed opposite each other. This invention relates to a moisture measuring device for soybeans, pigeon wheat, etc., which can accurately feed and crush individual grains and quickly detect moisture.

``Prior art'' 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 and accurately measuring the moisture content of the paddy. An automatic moisture measuring device for dried rice grains that can carry out drying work was developed before this application was filed, for example, by
This is known as described in Japanese Patent No. 49-16305, and its contents will be explained using FIG. 6. That is, crushing rolls 2, 2 are provided to crush a certain amount of supplied paddy during the circulation drying process, and a pair of crushing rolls 2, 2 are provided below the crushing rolls 2, 2 to detect resistance changes due to water content by pinching the crushed paddy. Moisture detection rolls 3, 3 are disposed, 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 roller 4. The main body houses the rolls 3, 3, 6 is a circulation elevator,
Reference numeral 7 denotes a charging gutter connected to the elevator 6 at the base end and to the dryer main body (not shown) at the distal end, and 8 is a switch for opening and closing the supply window 9 opened at an appropriate position in the charging gutter 7. Even if it is a valve, the supply window 9 has a main body 1.
The upper end side of the paddy is connected so that a part of the dried paddy can be supplied to the crushing rolls 2, 2 at any time by switching the switching valve 8, and the water content of the paddy can be automatically measured.

``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 grains of paddy and wheat, so the supplied paddy, wheat, etc. It is smoothly fed between a pair of crushing rolls and crushed without stagnation.

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 water content of each large grain cannot be accurately measured because there are many large grains to be measured. There was a problem that automatic drying of large grains could not be carried out more accurately.

The present invention was devised in view of the above-mentioned problems of the conventional technology, and its purpose is to solve the problem of one pair of large grains even if there are a plurality of large grains that are continuously supplied into the storage chamber. The large grain sorting boss cylinders rotate in opposite directions to separate and remove them.
Only one grain is accurately supplied between a pair of main and sub-moisture detection rolls, and after a single large grain is supplied between the main and sub-moisture detection rolls, automatic operation is performed according to the rotation of the large grain sorting boss tube. After the pressing movable body, which is moved up and down, is forcibly pressed toward the crushing gap, the main and sub-moisture detection rolls are rotated in the normal direction so as to face each other inward to crush the grains, and the moisture value of a single large grain can be accurately determined. The present invention aims to provide an apparatus for measuring the moisture content of soybeans, pigeon wheat, etc., which can measure the moisture content of soybeans, pigeon wheat, etc., and can facilitate the automatic drying of large grains.

"Means for Solving the Problem" In order to achieve the above object, the moisture measuring device for soybeans, pigeon wheat, etc. in the present invention crushes a main moisture detection roll and a sub moisture detection roll that are narrow in a storage chamber. Each shaft is mounted with a space between them so that they can rotate forward and backward.
On one side of the above-mentioned pair of main and sub-moisture detection rolls, there is a large particle feeding circumferential surface that is approximately the same as the diameter of the main and sub-moisture detection rolls, and a diameter that is smaller than the diameter of the main and sub-moisture detection rolls, on the circumferential surface of each symmetrical position. A large particle sorting boss tube is provided which is formed continuously with a large particle falling peripheral surface.

At a position above either of the main and sub-moisture detection rolls, a movable pressing roller is attached to the distal end side of the roller, which is constantly lowered elastically toward the crushing gap around a spring portion provided on the proximal end side. The pressing movable body is pushed up to the upper limit position by sliding contact with the large particle feeding peripheral surface.

The large grain sorting boss cylinder and the main and sub-moisture detection rolls are tilted as a whole so that the large grain sorting boss cylinder side is higher, so that the supplied large grains are transferred to the main and sub-moisture detection roll side.

In addition, for the above purpose, the main and sub-moisture detection rolls are formed with a width that allows one large grain to be rolled into a rolling position, so that one large grain is always crushed by the main and sub-moisture detection rolls, and one grain is crushed. This makes it possible to accurately detect moisture gradients.

"Function" Now, if you want to measure the moisture value of a single large grain, first turn the main and sub-moisture detection rolls 103 and 104 so that they face outward from each other as shown in FIGS. 3 and 4. Rotate. In this state, a plurality of large grains made of soybeans, pigeon wheat, etc., for example, about 15 grains, are fed between a pair of large grain sorting boss tubes 107 and 108 attached to one side of main and sub-moisture detection rolls 103 and 104.

Then, while the large particles are being transferred toward the main and sub-moisture detection rolls 103, 104 while rolling on the large particle sorting boss cylinders 107, 108 which are rotating in the opposite direction, the large particles fall onto the pair of large particle falling peripheral surfaces 113, 114. The large grains are sorted and dropped from the falling gap 〓'' formed in between, and some of them are conveyed toward the main and sub-moisture detection rolls 103 and 104 while rolling on the large grain feeding peripheral surfaces 111 and 112 that rotate in opposite directions while approaching each other. After that one grain is fed into the crushing gap, the other large grains are dropped from the gap formed between the pair of large grain falling peripheral surfaces 113 and 114. On the other hand, a pressing movable body 115, which is equipped with a pressing roller 117 on its tip side, which is always elastically lowered toward the crushing space with a spring portion 116 provided on the base end side as an axis, rotates in opposite directions to one another, for example, a large particle sorting boss cylinder 107. It is pushed up to the upper limit position by the sliding action with the large grain feed circumferential surface 111 provided on the circumferential surface, and then, when the sliding contact with the large grain feed circumferential surface 111 is finished, the spring part 116 is resiliently pushed up to the crushing position. Since the main and sub-moisture detection rolls 103 and 104 are operated so as to be lowered, a single large grain fed into the crushing space between the main and sub-moisture detection rolls 103 and 104 is forcibly pressed by the pressing roller 117 that is lowered elastically. Become. In this way, one large grain is transferred to the pressure roller 11.
7, the main and sub-moisture detection rolls 103,
104 and a pair of large grain sorting boss tubes 107, 10
8 is stopped, and then the above-mentioned members are rotated forward so that they face each other inward. Then, one large grain that has been pressed toward the crushing gap by the pressing roller 117 is crushed by the main and sub-moisture detection rolls 103 and 104, and at the same time, the moisture content of one large grain can be accurately measured. .

Therefore, when the moisture content of one large grain is measured by the above operation, the large grain sorting boss cylinder 10
Main and sub-moisture detection rolls 10 each having 7 and 108
No. 3,104 is for measuring the moisture content of large grains one by one by repeating reverse rotation and forward rotation again after stopping.
