Description

[Detailed Description of the Invention] The present invention relates to an improvement of the grain distributing device of a oscillating sorter, and is devised to perform efficient processing at the end of sorting work.

Although this type of oscillating sorting machine has high performance accuracy, it has the disadvantage of low capacity.

In order to put this highly accurate performance to practical use, it is necessary to use a sorting frame that is integrated with multistage sorting plates.

Therefore, the raw material grains are also divided into channels to be distributed to each tier, but at the end of the work, the grain layer becomes thinner, which affects the sorting performance, and it takes a long time until all the remaining amount is sorted out. However, this will result in a significant reduction in efficiency as the work progresses towards the end.

Conventionally, a known example of this type of sorting board equipped with a grain distribution device is the publication of Japanese Patent Publication No. 48-26145. Since the grains are directly supplied to the uppermost sorting plate, the grains flow down the supply pipe in an accelerated manner and diffuse onto the plate surface, thereby reducing the amount of grain formed on the sorting plate. This may greatly disturb the normal flow distribution state, causing the sorting action to temporarily stagnate, or the supply pipe may frequently come into contact with objects, etc. and move, causing the supply position to fluctuate, making the sorting action impossible. It had several defects.

Therefore, the present invention was developed to
By installing a grain distribution device with a unique structure, grain feeding to each stage sorting board is interrupted in a timely manner to supply grain only to the top stage board, and the grain fed to the top stage sorting board is kept at a constant flow rate. In addition, the flow is continuously supplied to the grain distribution box from the small compartment of the grain distribution box installed at almost the same position as the sorting board, thereby eliminating the various drawbacks of the conventional equipment mentioned above and ensuring normal sorting. The aim is to develop and provide a high-performance device that can continue its action all the way to the final stage.

To explain the present invention with reference to an embodiment diagram, a swinging sorting board 2 whose upper surface has a rough surface 1 is surrounded by side walls on three sides to form a sorting frame 3, and a plurality of these sorting frames 3 are arranged in a multi-tiered manner. Each sorting board 2...
The mixed grains of unhulled brown rice supplied to ... are sorted and separated into brown rice from the front side wall 4, paddy from the rear side wall 5, and mixed grains of unhulled brown rice between them, and are separated from the lateral end. A swinging distribution box 6 is installed at the upper part of the sorting board 2 to convey and supply grain to each sorting board surface, and the swinging distribution box 6 A plurality of discharge ports A to F are provided on the delivery side 8 on one side of the rectangular corrugated bottom plate 7, and these are surrounded by side plates to form a rocking box body, and the corrugated bottom plate 7 inside the box body.
A large compartment 10 has a partition wall 9 installed horizontally on the upper part of the partition wall 9, and a large compartment 10 having discharge ports E-F communicating with each stage sorting board 2a to 2e on both sides of the partition wall 9. Communicating 1
A small compartment chamber 11 having a plurality of discharge ports A is provided so as to form an integral structure, and each of the discharge ports A to F is connected to a flow path A' to F' of each stage sorting board 2a to 2e, respectively. It is designed so that the appropriate amount of grain can be continuously supplied to each stage sorting plate.

Branched distribution cylinders 13 and 14 are connected to the grain tank 12 provided at the upper part of the distribution box 6, and each compartment 10.
11, and each distribution cylinder 13.14 is provided with a switching valve 15.16 and a flow rate control valve 17.18, respectively, so that the grain stored in the grain tank 12 can be selectively supplied to each of the large and small compartments 10.11. It is formed like this.

With the above configuration, the mixed grain of paddy and brown rice in the grain tank 12 is transferred to the large compartment 1 of the swing distribution box 6 by opening the switching valve 15.
0, and is oscillated by the zigzag surface of the bottom plate 7 to rectify the appropriate amount in a plane shape, and divides the flow equally into the discharge ports B-F from the flow paths B' to F' to each stage sorting board 2a to 2. 2e, and is separated into mixed grains of brown rice, paddy, and unhulled brown rice by the oscillating sorting action of each plate, and is discharged from the end of each side for sorting.At the end of the operation, the amount of grain is When the grain tends to gradually decrease, the switching valve 15 is immediately closed, the switching valve 16 is opened, and the flow path of the distribution tube is switched to drain the remaining amount of raw material grain from the outlet A provided in the small compartment 11 to the maximum. A suitable amount is continuously supplied only to the upper sorting plate 2a at a constant flow rate, and the layer height is supplemented to perform normal specific gravity sorting.

Therefore, at the end of the sorting operation, a single sorting plate can perform a small-scale sorting operation corresponding to a small amount of raw grain.
It also has the effect of shortening the completion time at the end of the work.
