Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a device for transferring grains one by one to a moisture measuring device for a grain dryer.

[Prior Art and Problems Thereof] When treating grains, it is necessary to transfer the grains one by one, such as when measuring the water content of these grains. Paddy,
When measuring the moisture content of grains such as brown rice and milled rice, it is not possible to obtain the correct moisture value if green rice is mixed in the grains such as brown rice. This is a major obstacle to knowing the water content of the water, so it is necessary to send the grains one by one to the water content meter to measure the water content and to perform statistical calculation to know the total water content. For example, when measuring the water content of the paddy during drying with a circulating grain dryer, in a moisture meter that takes out the sample in the dryer and measures each grain with a measuring roll,
A transfer device is required to take the grains into the inspection roll one by one. As such a transfer device, there is Japanese Patent Application No. 63-14041 “grain transfer device” of the present applicant.

The outline of this application is that a pair of rolls, which are formed with mutually opposite outer threads and are rotatably supported in a state of being meshed with each other, and a pair of rolls engaged with each other in the direction in which the threads are separated from each other at the upper part It has a structure that includes a drive mechanism that rotates in opposite directions so as to move, and a discharge port that discharges the grains that have moved between the threads at the upper part of the meshing portion of the roll one by one. ing. However, when the grain transfer device based on this invention was attached to the grain dryer and the experiment with rice grains was repeated, as shown in Fig. 1, when there were extremely many paddy rice with long whisker-like branch stems, etc. It was found that the branch shoots of the paddy hit the entrance of the drainage port, making it difficult to drain the paddy and finally closing the drainage port completely.

[Object of the Invention] An object of the present invention is to provide a grain transfer device having a simple structure to prevent the clogging of the paddy.

[Configuration of the Invention] To achieve this object, according to the present invention, as the pair of corrugated screw rolls rotate, the roll surfaces move in directions away from each other, and each grain in the meshing part Transferred from one end of the wave screw thread to the other end,
In a transfer device configured to be transferred between one end of a roll and the other end between threads, by providing a cutter that rotates integrally with the roll on the discharge side of at least one roll, Provided is a grain transfer device capable of preventing clogging of a discharge port.

[Operation and effect of the device] When there is a large number of branch buds in the grain that is a sample in this type of grain transfer device, if the movement of one grain of paddy stops due to the effect of this branch bud, the The paddy that is continuously transferred loses its place of arrival, is accumulated more and more, and eventually plugs the discharge port. In order to solve this problem, in the present invention, by providing a cutter that rotates integrally with the roll on the outlet side of at least one roll, and cuts the branch branch at least once per rotation, Even if the paddy stopped once, it cuts off the branch part of the paddy in one rotation, so that it no longer accumulates and clogs the outlet.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a state in which a grain is caught in a conventional grain transfer device. FIG. 2 shows the entire moisture measuring apparatus 1 including the grain transfer apparatus 10. In FIG. 2 ', the grain transfer device 10 includes a pair of rolls 12,14. These rolls 12 and 14 have external threads formed in the shape of right-hand thread and left-hand thread, respectively.
These outer threads are rotatably attached to the support plate 11 so that they are engaged with each other. Shafts of rolls 12 and 14 are supporting plates 1
It extends from 1 through the bearing plate 13 and has gears 8, 8'fixed at each end. The gears 8,8 'mesh with each other on the gear 6 mounted on the drive 5 and thus
The rolls 12 and 14 can rotate synchronously.

A block 2 having a mountain-shaped outer peripheral surface is attached to a mounting plate 11 in front of the upper discharge port 9 of the rolls 12 and 14. Reference numeral 18 is a moisture measuring electrode, which is a set of roll-shaped electrodes in the embodiment, and the detection signal is sent to a moisture display unit (not shown). The operation of the grain transfer device and the effect of the repellent member according to the present invention will be described with reference to FIGS.

The grain 20 sent over the rolls 12 and 14 is forced to enter under the block 2. Block 2 is shown in Figs.
As is clear from the figure, it is a forced discharge member having a mountain-type outer peripheral surface that contacts the outer peripheral surfaces of the rolls 12 and 14, and when the fed grains have a large amount of straw rice or rice with branch shoots,
The branch vein stagnates so as to block the outlet 9 provided in the mounting plate 11. If one branch grows like this, paddy rice will stagnate one after another, and eventually it will get caught up in the roll axis. In such a situation, as shown in the drawing, the cutter 3 is attached to the roll, so that the branch stem and the straw debris that have blocked the discharge port 9 serve to cut while rotating. The unhulled rice that has become entangled once the branch shoots have been cut is easily discharged through the discharge port 9 and does not stagnate the next unhulled rice. By the action of the forced discharge member 2 and the cutter 3, moisture measurement is performed. The grains smoothly drop through the discharge port 9 to the electrode roll 18.

Further, by providing the air-selecting device of reference numeral 19, the cut branches, straw waste, crushed grains, etc. are removed, and only the grains used for moisture measurement can be dropped onto the electrode roll 18.

Although the cutter is attached to only one roll in the embodiment, it may be attached to both rolls.
