Specific embodiments
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1 - 5 , an embodiment provided by the present utility model: a crop seed screening device, including a sieve box 1, a collection box 3 and a hopper 7. The top of the sieve box 1 is provided with a slot 2 at the bottom of one side of the sieve box 1. The collection box 3 is arranged inside the slot 2. The top inside the sieve box 1 is provided with a material box 4. One side of the bottom of the material box 4 is provided with a blanking chute 5. The top of the material box 4 is provided with a top chute 6. The hopper 7 is arranged inside the top chute 6. The top of one side of the material box 4 is fixed with a first positioning plate 8. The bottom of the first positioning plate 8 is provided with a first electric push rod 9. The bottom of the first electric push rod 9 is provided with a second positioning plate 10. One side of the second positioning plate 10 is fixedly connected with the outer side wall of the sieve box 1;
[0025] Specifically, as Figure 1 and Figure 3 shown, during use, start the second electric push rod 14 to extend, and the partition board 13 can be moved outwards. By means of the movement out of the partition board 13, the internal channel of the material box 4 and the opening size of the blanking chute 5 can be reduced, and the adjustment process of the seed falling can be indirectly completed;
[0026] On one side inside the material box 4, a blanking adjustment component is provided. The adjustment component includes a diversion platform 11, a chute 12, a partition 13, and a second electric push rod 14. A diversion platform 11 is installed on one side inside the material box 4. At the bottom end of one side of the diversion platform 11, a chute 12 is provided. Inside the chute 12, a partition 13 is movably installed. Inside the partition 13, a second electric push rod 14 is installed. On the inner side wall of the sieve box 1, a sieve platform 15 is installed. Inside the sieve platform 15, a sieve mesh 16 is installed. At the bottom end of the sieve platform 15, a mounting frame 17 is installed. There are four groups of mounting frames 17 installed at the bottom end of the sieve platform 15, and the four groups of mounting frames 17 are symmetrically distributed. On one side of the mounting frame 17, a micro motor 18 is installed. On one side of the micro motor 18, a cam 19 is installed;
[0027] Specifically, as Figure 1 , Figure 3 and Figure 4 shown, during use, start the first electric push rod 9 to extend, which can assist in pushing the material box 4 to move upward along the sieve box 1. With the upward movement of the material box 4, the height position of the material box 4 during use and the height of the seeds falling inside can be adjusted. The sieve mesh 16 can be made of a material with certain elastic deformation. When the bottom micro motor 18 drives the cam 19 to rotate, as the cam 19 intermittently contacts the bottom side of the sieve mesh 16, it assists the sieve mesh 16 in performing a shaking and screening operation;
[0028] On the other side of the sieve box 1, a mounting groove 20 is provided. On one side of the mounting groove 20, an air box 21 is installed. Inside the air box 21, a filter plate 22 is installed. On one side inside the air box 21, a fan 23 is installed. On one side of the air box 21, an air groove 24 is provided. At the bottom end of the air box 21, a sewage discharge pipe 25 is fixed. On one side of the sewage discharge pipe 25, a fixing bolt 26 is provided. One side of the fixing bolt 26 extends into the sewage discharge pipe 25. Inside the sewage discharge pipe 25, a collection box 27 is provided;
[0029] Specifically, as Figure 1 and Figure 5 shown, during use, when starting the fan 23 inside the air box 21, the air flows into the air box 21. At this time, when the seeds fall, the lighter sundries such as dust mixed inside the seeds can follow the air flow into the air box 21 and are filtered by the filter plate 22. Later, they can fall into the collection box 27 for collection. When the fixing bolt 26 is turned loose, the collection box 27 can be removed to process the collected sundries.
[0030] Working principle: During use, the material conveyor transports seeds to the hopper 7 at the top of the feed bin 4. Subsequently, the seeds can fall into the feed bin 4 through the hopper 7 and drop through the blanking chute 5 at the bottom of the feed bin 4. If the first electric push rod 9 is activated, it can drive the feed bin 4 to move upward to adjust the height position of the feed bin 4. If the second electric push rod 14 is activated, it can push the partition 13 inside the feed bin 4 to move outward from the deflector 11. By means of the movement of the partition 13, the channel sizes inside the feed bin 4 and the blanking chute 5 can be reduced, and the falling of seeds can be reduced. Thus, by adjusting the position of the partition 13, the control of seed blanking is completed. If the fan 23 inside the air box 21 is activated, an air flow can be generated and move into the air box 21. When the seeds fall, the lighter sundries such as dust mixed in the middle can enter the air box 21 along the air flow. The filter plate 22 inside the air box 21 can filter the dust and sundries. Later, they can fall into the collection box 27 below. After the falling seeds land on the sieve mesh 16, screening operation is carried out with the help of the sieve mesh 16. When the micro motor 18 below is activated, it can drive the cam 19 to rotate. The protruding end of the cam 19 continuously contacts the bottom side of the sieve mesh 16 and slightly lifts the sieve mesh 16 to form vibration, so as to assist the sieve mesh 16 in screening the seeds. By opening the side door on the front of the sieve box 1, the seeds on the surface of the sieve mesh 16 can be processed. The falling seeds are collected in the collection box 3 below and wait for centralized processing.
[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
