Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain feeding device for a rice huller.

BACKGROUND OF THE INVENTION Conventionally, this type of grain feeding device detects the layer thickness of grains fed to the starting end of a rotary sorting tube, and uses this detection to adjust the amount of paddy to be fed to the husking device. The thickness of the grain layer inside the sorting cylinder was kept approximately constant.

Problems to be Solved by the Invention The supplied paddy is husked by a husking device, and the husked rice is mixed with the husks.The husks are mixed with the husks. In the huller, a grain layer is formed in the sorting cylinder by the supplied grains, and while the grains are being transferred, the grains are repeatedly scooped up by a recessed part in an ascending sorting process and a descending process in which they fall. Sorting is done while Changes in the grain layer in the sorting cylinder occur due to increases or decreases in the supply amount, which tends to adversely affect the sorting performance. If the thickness of the grain layer formed in the sorting cylinder is automatically adjusted in conjunction with the opening of the paddy supply control valve to which the paddy is supplied to the phusher by vertical movement of the valve, the phusher can be The grains that are slid out of the device and transferred and supplied into the sorting cylinder are delayed due to passing through the transfer path, and the response to changes in the grain layer is slow, making it difficult to quickly stabilize the grain layer thickness, and the sorting accuracy is affected. can also have a negative impact.

Means for Solving the Problems This invention provides a sorting tube (2) which has a recess (1) formed on its inner circumferential surface into which the grains can fit, and which rotates to sort the grains.
A sensing valve (3) is provided at the starting end of the sorting tube (2) that rotates up and down depending on the layer thickness of the grains to be fed. -1- due to the increase or decrease in the amount of grains received from 4)

Functions and Effects of the Invention The scraped rice scraped out by the scraping device (4) is supplied to the grain supply tank (5), and this supply tank (5) The grains are fed into the starting end of the sorting tube (2) which rotates while moving up and down, and the fed grains form a grain layer necessary for sorting on the inner peripheral surface of the sorting tube (2), and the rotation increases. The grains are scooped out by the recess (1) on the side and are transferred to the terminal side for sorting while repeating the sorting action of the -H sorting process and the descending process in which some of the grains fall. During this process, the type of grain supplied may change, or the sorting tube (
Due to changes in the rotation speed of 2), the sorting cylinder (2)
If there is a change in the amount of grains fed into the starting end, the thickness of the grain layer formed in this sorting tube (2) will also change,
Depending on the layer thickness of this grain layer, the sensing valve (3) rotates upward F, and when the number of grains increases, the sensing valve (3) rotates upward, and the supply control valve (5) of the supply tank (5) rotates upward. 6) in the closing direction, or conversely when the grains decrease, the sensing valve (3) rotates downward and is interlocked to adjust the supply control valve (6) of the supply tank (5) in the opening direction. At the same time, if the supply tank (5) moves due to the opening/closing operation of the supply tank (5), the opening degree of the paddy supply control valve (7) to supply paddy to the husking device (4) will be increased. When the supply tank (5) moves downward in the direction or vice versa, the opening degree of the paddy supply control valve (7) is adjusted in the closing direction.
It is possible to constantly replenish the supply tank (5) with an appropriate amount of grains, and to feed grains into the sorting cylinder (2) in immediate response to the rotation of the sensing bulb f (3), thereby facilitating sorting. The grain layer required for this process can be quickly stabilized, and the stability and accuracy of sorting can be improved by 7L.

In addition, as in the embodiment, the supply control valve (

During this hulling operation, the sensing valve (3) rotates downward depending on the grain layer thickness of the grains supplied into the starting end of each sorting tube (2). The grain layer formed in the sorting tube (2) may increase due to a change in the variety of grain, or by changing the position of the brown rice control valve (25) by operating the control lever (28) to change the efficiency. For example, this change in grain layer thickness causes the sensing valve (3) to rotate upward, and in conjunction with this rotation, the supply control valve (6) of the supply tank (5) operates in the closing direction. If the grain layer in each sorting tube (2) is maintained in almost the best condition, and the amount of grain in the supply tank (5) increases with the closing of the supply control valve (6), the spring (37), this supply tank (5) moves downward, and the opening degree of the paddy supply control valve (7), which is to supply paddy to the hulling device (4), is linked to the closing direction. (5) Adjust the amount of accumulation to an almost optimal state. Conversely, if the grain layer in the sorting tube (2) decreases, this change in grain layer thickness causes the sensing valve (3) to rotate downward, and in conjunction with this rotation, the supply control valve ( 6) operates in the opening direction to maintain the grain layer in each sorting cylinder (2) in almost the best condition, and the supply control valve (6)
) is opened and the amount of grains in the supply tank (5) decreases, the spring (37) causes the supply tank (5) to open.
moves upward, and the opening degree of the paddy supply control valve (7) is interlocked with the opening direction to adjust the amount of grain layered in the supply tank (5) to a substantially optimum state.

This makes it possible to supply the appropriate amount of grain to each of the multiple sorting tubes (2), and to quickly stabilize the grain layer in response to changes in grain layer thickness due to changes in conditions. , it becomes easy to improve sorting accuracy and throughput.
