A power supply (not shown) is arranged on the special-shaped bracket 14.
The working principle is as follows: when the grains aired on the ground are required to be collected, firstly, a grain bag penetrates through the lower part of the bag opening clamping ring 24, the bag opening of the grain bag is outwards rolled on the bag opening clamping ring 24, so that the collected grains can conveniently fall into the grain bag through the collecting device, in order to ensure that the grain bag is more firmly fixed, the bag opening of the grain bag rolled on the bag opening clamping ring 24 can be further clamped by a clamp, after the fixing is finished, the driving motor 36 is started to work to push the conveying device to advance, the auger 3 is driven to rotate through the transmission mechanism in the advancing process of the conveying device, meanwhile, under the action of the material stirring mechanism, the conveying pipeline 1 enables the grains to enter the inside of the conveying pipeline through the opening end of the conveying pipeline and to be conveyed to the other end of the conveying pipeline through the auger 3 and fall into the blanking box 15 through the blanking port 10, at the moment, the driving motor 36 drives, the connection key 33 is driven to rotate under the matching of the driving gear 37 and the driven gear 35, the hollow shaft 20 is driven to rotate under the matching of the key groove 34 and the connection key 33 in the rotating process, in the rotating process of the hollow shaft 20, when two support legs 39 on the bottom end of the tray 30 pass two second bulges 41 from the plane of the upper end of the fixing ring 32 at the same time, the tray 30 drives the hollow shaft 20 to ascend and overcome the acting force of the compression tension spring 38, when the support legs 39 ascend to the topmost ends of the second bulges 41, the feed inlet 25 ascends to the inside of the blanking box 15 along with the support legs and is separated from the bottom end of the blanking box 15, the feed inlet 25 is opened, meanwhile, the impurity suction inlet I28 ascends along with the support legs and is completely separated from the impurity suction inlet II 29, so that the impurity suction inlet 28 and the impurity suction inlet II 29 are blocked, at the moment, grains in the blanking box 15 enter the upper end of the hollow shaft 20 through the feed inlet When the connecting key 33 continues to drive the hollow shaft 20 to rotate on the tray 30, as shown in fig. 5, when the supporting leg 39 leaves the second protrusion 41 and moves to the first protrusion 40, the hollow shaft 20 descends under the action of the tension spring 38 until the feeding port 25 contacts with the bottom end of the blanking box 15 again and is blocked, at the same time, the first impurity suction port 28 and the second impurity suction port 29 coincide again, under the action of the fan 21, the inner space of the hollow shaft 20 below the conical partition 26 generates negative pressure, and under the action of the negative pressure, the lighter-weight cereal shells sequentially pass through the second impurity suction port 29 and the first impurity suction port 28 and enter the hollow shaft 20 from the bottom end of the hollow shaft 20 into the impurity removing hood 18, and finally are collected in the collecting bag 22, and at the same time, under the action of the centrifugal force of the tray 30, the cereal is thrown out from the edge of the discharging pipe of the tray 30 and falls into the cereal 17 from the gap between the tray 30 and the inner wall of the sieving shell 16, the grains after being screened enter the grain bag through the grain discharge pipe 17, so that the separation operation of the grains and the grain shells is completed, and the grains after being dried in the sun are collected to be clean.
Therefore, the hollow shaft 20 is driven to rotate under the matching of the connecting key 33 and the key groove 34, and intermittent blanking is realized in the rotating process, so that the tray 30 bears and bears quantitative grains, and meanwhile, the quantitative grains are screened, and the grain shells mixed in the grains are screened out so as to collect clean grains.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
