Description

Grain picker {AIR DUCT FOR SORTING GRAINS}

The present invention relates to grain tuyere, more specifically, in the agricultural tuyere consisting of a grain input hopper and the wind power of the wind sorting unit discharge outlet and the grain discharge portion that the selected grain flows to the outside, the opening and closing device installed in the inlet of the grain input hopper The plate is configured to be inclined, the top of the windscreen selector is installed at the outlet, and the top of the exhaust structure is detachable, and the secondary slope plate is further provided while improving to conceal the holes drilled in the inclined plate of the grain outlet.

Conventional grain tuyere is known as Utility Model Registration Nos. 20-0421116 and 20-0445349.

Therefore, in the conventional grain sorting tuyere, the opening and closing plate installed in the grain inlet is a horizontal plate, which does not flow easily when the grain is introduced into the sorting unit, and thus the inconvenience of the feeding operation is not smooth, and the exhaust control panel of the wind sorting unit can be detached and detached. There was an inconvenience in that the size of the exhaust port could not be adjusted smoothly.If the exhaust control plate was broken, there was a disadvantage in that the treatment was inconvenient.The hole was drilled in the inclined plate flowing down when the sorted grain was discharged from the sorting section. When the abnormal grains are sorted, the grains falling down fall into the holes of the inclined plate so that they are not contained in the designated container. When the selected grains fall to the top of the inclined plate, the falling grains fall on the discharge port to come into contact with the perforated holes in the inclined plate. There is no chance that fine particles or foreign substances mixed in grains are not screened. There was no inconvenience.

The present invention has been developed to solve the inconvenience.

The present invention is configured to adjust the opening and closing angle by mounting the inclined opening and closing plate in the inlet of the grain input hopper for supplying the grain to the wind power sorter in the wind turbine for grain sorting, It is easy to adjust the angle while allowing the chaff to be detachable from the discharge port.The chaff can be selectively used by attaching a cover plate without a hole on the top of the inclined plate so as to conceal the hole drilled on the inclined plate of the grain discharge part. In addition, an additional inclined plate that is inclined toward the center of the inclined plate from the outlet side on the inclined plate outlet side of the grain discharge part to further increase the effect of the grain selection.

Since the present invention has an inclined opening and closing plate 3 at the grain inlet 2a of the grain input hopper 2, the grains waiting in the grain portion are deposited on the inclined plate so that the inlet can be easily made during the inlet. Since the interval of the fine can be finely adjusted according to grain size, the input amount can be adjusted according to the grain size, so it can be added to enhance the screening effect. The support shaft rods 5c and 5d mounted on the coil springs 5f are mounted on the coil springs 5f to deviate from the outside to the inside, so that they can be detached from the support shaft holes 4b drilled on both side walls of the outlet. Therefore, it is easy to install or remove the chaff at the outlet and the male thread bar (5h) formed at one side of the outlet adjustment plate. Since it can be moved from the ball 4c and the fixing nut 6 can be tightened to fix it, the angle of installation of the top of the discharge structure top plate is precisely adjusted, and the direction of the wind discharged to the outlet can be adjusted. There is an advantage to increase.

Then, there are narrow coupling holes 7b at both ends of the inclined plate 7a provided in the discharge groove of the grain discharge part 7, so that the blanking plate 8 without holes is folded over the inclined plate 7a and pushed up. When the inclined surface 8a 'of the engaging projection 8a on the bottom of the shielding plate enters the engaging hole, and moves the shielding plate back down slightly after entering the engaging hole, the locking groove 8a "of the engaging projection 8a becomes the engaging hole. (7b) Since it is caught and fixed to the inner surface, it is possible to cover up the inclined plate (7a) with holes to sort out the fine grains, and when removing the blind plate, while pushing the bottom upwards slightly lifted up the engaging projection (8a) ) Can be separated, so the separation and coupling of the screen plate is also easy to obtain a higher value of use.

In addition, an inclined plate center portion of the inclined plate 7a installed on the grain discharge part of the present invention is equipped with an auxiliary inclined plate 9 which is inclined toward the central portion of the inclined plate from the upper side of the outlet side of the inclined plate. Induced to flow down to the outlet through the inclined plate (7a) because it has the advantage of selecting the foreign matter falling to the outlet side of the inclined plate (7a) has the advantage that the selection of foreign matters has the advantage to increase the efficiency further .
