Description

[Detailed description of the invention] Industrial field of application This invention mainly focuses on a small number of grains of one to three grains, even if the surface is particularly smooth and the grains are large (such as soybeans, pearl barley, etc.). This invention relates to a grain moisture measuring device that can accurately feed grains between sub-moisture detection rolls, crush them, and quickly detect moisture.

Conventional technology Conventionally, multiple grains (for example, 10 or more grains) during circulation drying
A drying method that allows accurate drying work by automatically measuring the moisture content of the paddy by accurately collecting the paddy without removing it manually and crushing the paddy using a pair of moisture detection rolls. An automatic rice grain moisture measuring device is known and was described in, for example, Japanese Patent Publication No. 16305/1983 prior to the filing of this application, and its contents will be explained using FIG. 4.

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, which 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, 6, which stores the rolls 3, 3,
A circulation elevator, 7 a charging gutter connected to the elevator 6 at the base end and the dryer main body (not shown) at the distal end, and 8 opening and closing a supply window 9 opened at an appropriate location in the charging gutter 7. The upper end side of the main body 1 is connected to the supply window 9, and the switching valve 8
A part of the dried paddy is crushed by the crushing roll 2,
The structure was such that the water content of the paddy could be automatically measured by supplying the rice to 2.

Problems that the invention aims to solve By the way, conventional automatic moisture measuring devices of this type were intended for small grains of paddy and wheat that had rough surfaces and were soft, 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 water content of one to three large grains cannot be accurately measured because there are many large grains to be measured. However, a problem arose in that automatic drying of large grains could not be performed more accurately.

Means for solving the problems The present invention solves the above problems, and includes:
The contents will be explained below using FIGS. 1 to 3 corresponding to the embodiment. That is, a storage chamber 103 in which a main moisture detection roll 104 and a sub moisture detection roll 105 are rotatably arranged opposite each other with a crushing gap therebetween.
will be established. At the supply port 106 of the storage chamber 103, there is a grain supply cylinder 113 supported by a pressure roller 111 that can be slid up and down toward the crushing gap by the rotation of the main moisture detection roll 104 about the spring part 108 on the base end side. Installed vertically so that it can slide up and down. And upper and lower surfaces 113a, 11 of the grain supply cylinder 113
3b and the side surface 113c facing the sub-moisture detection roll 105 side are both opened. The above side surface 113
c An opening regulating plate 115 is installed vertically on the front surface of the opening side, and the opening above the opening regulating plate 115 is configured as a grain supply window 116, and the opening below the opening regulating plate 115 is configured as a grain discharging window 117. This is what I did.

Function If you want to measure the moisture value of a single large grain, first rotate the main moisture detection roll 104 and the sub-moisture detection roll 105 in the direction of the arrow, and measure the large grain that is being circulated (for example, soy,
) is supplied toward the supply port 106. Then, as the main moisture detection roll 104 rotates, the pressure roller 111, which was positioned so as to look into the crushing gap for the spring part 108 provided on the proximal end side, will move up and down around the spring part 108 as an axis. It is moved back and forth in the direction. Therefore, the pressure roller 11
Grain supply tube 113 whose lower end was supported by 1
is slid in the vertical direction as the pressing roller 111 slides up and down, and the supplied large grains are inserted into the grain supply cylinder 113 in a single file through the grain supply window 116 by the vertical sliding operation.

However, when the press roller 111 is in the crushing gap position (i.e., the grain supply tube 113 is in the lowest position), the large grains inserted in a single file into the grain supply tube 113 are separated by the pressure roller 111 and the sub-moisture detection roll. 105 to prevent large grains from being accidentally discharged from the grain discharge window 117, large grains are not discharged from the grain discharge window 117, but once the main moisture detection roll 104 rotates, the pressure roller 111 is forced to When the grain supply cylinder 113 is slid upward and moves away from the sub-moisture detection roll 105, the grain discharge window 117 opens to a size sufficient to discharge one large grain. One large grain is discharged from the grain discharge window 117 to the crushing gap position. Therefore, one large particle discharged to the crushing gap position is forced into the crushing gap by the pressing roller 111, which is automatically moved downward by the elastic force of the spring part 108 as the main moisture detection roll 104 rotates. The moisture value of one large grain can be accurately measured at the same time as it is pushed into the grain and crushed by the main and sub-moisture detection rolls 104 and 105.

Therefore, the main and sub-moisture detection rolls 104, 10
5, the large grains supplied to the supply port 106 are supplied to the crushing gap for each grain by the above-mentioned operation, and the moisture value of each large grain is accurately measured, and based on the moisture value, Large grains can be dried well.
