Description

[Detailed description of the invention] The present invention is a soybean sorter that sorts soybean grains threshed from soybean husk culms, and the selected grains taken out from the outlet of the soybean culm are crushed husk waste and zero-grain crushed waste. In order to ensure that grains are not mixed in, a combination of a winnow and a dust collection bag is installed in a part of the hopper for receiving grain of the grain frying machine that feeds the grain to the sorting device. This invention relates to a dust removal device for a soybean sorter that is capable of removing crushed debris and the like from the fed grains to be sorted through an airway and collecting the removed crushed debris.

Next, the device of the present invention will be explained in detail with reference to the drawings according to the embodiments. 1 is a machine frame of a soybean sorting machine A that is formed into an appropriate shape, a is a sorting device mounted on the machine frame 1, and b is the machine frame of the soybean sorting machine A. This is a grain frying machine attached to feed soybean grains to be sorted to the sorting device a.

The sorting device a separates irregularly shaped waste grains from the soybean grains fed by the grain lifting machine. A sorting belt conveyor 2 is installed so as to be tilted in the direction of the belt, and a rotating cylindrical sieve 30 is supported so that its axial direction is tilted in order to separate the long grains that are separated by the waste grains by the conveyor 2 according to particle size. do,
A cylindrical particle size sorter that separates soybean grains received through one opening 31 of a cylindrical sieve 30 into large grains coming out from the other opening 32 and medium and small grains leaking through the sieve openings of the cylindrical sieve 30. It consists of machine 3.

Then, the sorting belt conveyor 2 and the particle size sorter 3 collect the long particles that fall from the side edge 2C on the side that slopes downward while being conveyed on the conveyor 2 to the bottom of the sorting belt conveyor 2. A grain receiving gutter 4 is provided, and a hopper 40 connected to the descending end of the grain gutter 4 is communicated with one opening 31 serving as a reception port of the particle size sorter 3, thereby reducing the transfer surface of the sorting belt conveyor 2. While the soybean grains supplied from the grain lifting machine to the starting end 2a of the (sorting surface) are conveyed to the ascending terminal end 2b, the waste grains are removed and the soybean grains become cylindrical. This is a connected combination to be fed to the particle size sorter 3.

Further, a box 50 is provided below the terminal end 2b of the sorting belt conveyor 2 in the conveying direction (indicated by arrow A in FIG. 1) to receive the waste grains carried out from the terminal end 2b. Beneath each of the funnel parts 33, 34 provided below the body peripheral wall of the cylindrical sieve 30 of the cylindrical particle size sorter 3, there are boxes 51, 52 for taking out medium particles and small particles. Furthermore, a box 53 is disposed below the opening 32 on the downwardly inclined side of the cylindrical sieve 30 to take out large grains.

The grain lifting machine is equipped with a packet conveyor that rotates endlessly in the vertical direction inside the grain lifting tower 60. When soybean grains are inputted from the hopper 62, the packets circulating inside the grain lifting tower 60 carry the soybean grains upward and are discharged into the discharge cylinder 63 installed at the top of the grain lifting tower 60. The soybean grains flowing out from the tip of the discharge tube 63 are discharged from the tip of the discharge tube 63 to the starting end 2a of the conveying surface of the sorting belt conveyor 2. It is arranged and installed in the machine frame 1 so that it is fed to the top surface.

Reference numeral 7 denotes a primary hopper arranged above the grain receiving hopper 62 attached to the grain lifting machine;
is arranged so as to face above the upper opening 62a of the hopper 62.

A space 8 is formed between the lower lower part 0 of this next hopper 7 and the upper opening 62a of the hopper 62 for receiving grains.
The soybean grains to be sorted are fed into the primary hopper 7. The soybean grains to be sorted are fed into the primary hopper 7. Then, while the soybean grains are falling into the hopper 62 communicating with the receiving port 61 of the grain lifting machine, the air outlet 9 of the winnowing machine 9
The soybeans that are mixed into the soybean grains are blown out from the soybean grains by the sorting wind that blows across the space between the lower lower 0 of the next hopper 7 and the upper opening 62a of the hopper 62. This is so that the crushed debris generated during threshing of grains is removed by wind separation.

Furthermore, a dust collection bag C made of a fine mesh is removably attached to the opening 80 of the sorting air passage 8 that blows the air out of the machine together with the air-selected crushed debris. This is so that the exhaust air that has been air-selected and blown out from the open port 80 is discharged outside the machine while leaving the crushed debris in the exhaust air filtered in the dust collection bag C. It's Nishide.

As explained above, the dust removal device in the soybean sorting machine according to the present invention utilizes the hopper 62 of the grain lifting machine that feeds soybean grains to be sorted to the sorting device a. The materials to be sorted to be sent to a are air-selected in advance by the sorting air of a chisel 9, and the crushed debris etc. discharged with the exhaust air during wind selection are removed from the open port through which the exhaust air is discharged. Since the dust collection bag C made of a mesh provided at 80 is used to collect the particles, the selected particles are sorted and taken out by the sorting device a.
This eliminates the contamination of crushed debris, eliminates unnecessary burden on the sorting device a, improves the accuracy of sorting, and facilitates the disposal of the crushed debris to be removed.
