Technical Field

[0001] The invention relates to the grain production industry, in particular to a device and method for sorting good and bad grains used in grain production. Background Art

[0002] In the field of grain production, grain quality control is of vital importance, among which, grain sorting is a key link. In actual production, there are significant differences in the dryness and weight of grains, which puts forward specific requirements for sorting devices. From the scale of grain production, with the development of agricultural technology and the expansion of planting area, grain output has increased significantly. The traditional method of relying on manual experience to judge the quality of grain is far from meeting production needs. Manual sorting is not only extremely inefficient, but also when faced with a large amount of grain, human sensory judgment is prone to errors, resulting in inaccurate sorting results.

[0003] In some existing grain sorting technologies, some devices only focus on screening the appearance factors such as grain size and shape, but there are deficiencies in the sorting method for the important indicator of weight, resulting in insufficient grain sorting precision. In view of the above problems, it is urgent to develop a better grain production sorting device and sorting method that can better meet the needs. Summary of the invention

[0041] S105, close the blowing member 702, and the secondary unqualified grain particles fall onto the collecting trough plate 704 at the corresponding height, completing the secondary sorting of good and bad products, and open the box door 201 to take out the bad grain particles.

[0042] The working principle of the present invention is as follows: the grain particles to be sorted are stored in the guide cone barrel 203, and the first adjustment control unit 204 can control the discharge of the grain particles in the guide cone barrel 203. When the first adjustment control unit 204 is turned on, the grain particles in the guide cone barrel 203 can be guided to fall onto the saturation screening device 3 at the bottom, and the unsaturated (unqualified particle size) shriveled particles are screened by the saturation screening device 3. At the same time, the selected saturated particles can be collected in a centralized manner through the primary separation device 4, and then the selected shriveled particles can be guided to fall into the gravity screening device 5, and the gravity screening device 5 can further sort the shriveled particles, and the quality difference can be used to sort out the superior and inferior grain particles in the shriveled particles. The baffle 304 is hollow and inverted "L" shape. A through groove (not shown in the figure) is provided on the inner top of the baffle 304. When the first driving member 30 1 is running, and cooperates with the flexible connecting seat 302 to drive the sieve plate 303 to vibrate slightly. The first sieve 305 embedded in the sieve plate 303 is used to vibrate and screen the grain particles falling on the sieve plate 303. The sieve plate 303 is provided with multiple groups, which can further improve the screening accuracy. The grain particles that fail to pass the screening will gather at the connection position between the baffle plate 304 and the sieve plate 303, waiting to be collected by the primary separation device 4. When the saturated screening device 3 is sorted, the negative pressure member 406 is opened, and negative pressure can be formed inside the storage box 405, the first connecting pipe 402, the second connecting pipe 404 and the baffle 304. The unqualified grain particles gathered at the connection position between the baffle plate 304 and the sieve plate 303 can be introduced into the baffle plate 304 through the through groove on the top of the inner side of the baffle plate 304, and then introduced into the first connecting pipe 402, the second connecting pipe 404 and the storage box 405 in sequence;

[0043] The guide trough 602 is arranged below the bottom end of the bottommost sieve plate 303, and the unqualified grain particles sorted by multiple groups of sieve plates 303 fall on the second fixed frame 601, and the specifications of the screen 305 inside the bottommost sieve plate 303 are limited, so that the unqualified grain particles falling on the second fixed frame 601 are all in front of the push plate 604. When the second driving member 603 is running, it can drive the push plate 604 to reciprocate on the second fixed frame 601, and push the unqualified grain particles falling on the second fixed frame 601 into the guide trough 602. The second driving member 603 is not limited to an electric telescopic rod, and can also be driven by a linear motor, an electric cylinder or a cylinder, etc., as long as the movement and adjustment of the push plate 604 can be achieved. No specific limitation is made here. A plurality of collecting trough plates 704 that are movably connected to the separation box 701 are provided. When the second adjustment control 703 is turned on, the grain particles in the guide trough 602 can fall into the separation box 701. , and then the second control unit 703 is closed. Holes with a diameter much smaller than the grain particle size are provided on the bottom and top sides of the separation box 701. When the blowing member 702 is running, a certain upward wind force can be generated inside the separation box 701. The wind force value is fixed. The quality of high-quality grain particles is higher, and the quality of grain particles with insect pests or defects is lower. They will be blown up to a certain height with the upward wind force. After a certain period of time, the third driving member 705 at the corresponding position is opened, which can drive the collection trough plate 704 of the corresponding height to be inserted into the separation box 701, and then the blowing member 702 is closed. The secondary unqualified grain particles fall on the collection trough plate 704 of the corresponding height, completing the secondary sorting of good and bad products, opening the box door 201, and taking out the inferior grain particles. The third driving member 705 is not limited to an electric telescopic rod, and can also be driven by a linear motor, an electric cylinder or a cylinder, etc., as long as the movement and adjustment of the collection trough plate 704 can be achieved, and no specific limitation is made here.

[0044] In summary, through the multi-stage screening method, the grain particles can be screened comprehensively and carefully, the screening accuracy can be improved, and the incomplete and shriveled grains and saturated grains can be effectively separated. According to the different qualities of high-quality grain particles and grain particles with insect pests or defects, the upward wind force generated by the blowing is used to perform secondary sorting of high-quality and low-quality products, thereby more accurately separating grain particles of different quality grades.
