Description

Technical Field

[0001] The invention belongs to the technical field of seed selection equipment, in particular to a wheat seed sorting device. Background Art

[0002] A general term for wheat plants, which are monocots and are widely grown in the grass family around the world. Wheat caryopsis is one of the staple foods of humans. It can be ground into flour to make bread, steamed buns, biscuits, noodles and other foods; it can be fermented to make beer, alcohol, liquor (such as vodka), or biofuel. Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin, vitamin A and vitamin C, etc. Wheat is one of the three major grains, almost all of which is used as food, and only about one-sixth is used as feed.

[0003] At present, wheat seeds need to be selected before they are planted. The seed selection operation can be used to remove the shriveled seeds and impurities mixed in the wheat seeds, thereby improving the survival rate of the wheat seeds and increasing the wheat planting yield. In the prior art, the selection of wheat seeds is mostly achieved with the help of seed selection equipment. The existing seed selection equipment can be roughly divided into wet seed selection equipment and dry seed selection equipment. When wet seed selection equipment is used to select wheat seeds, it is mostly necessary to soak the wheat seeds in a water container. By virtue of the different buoyancy between shriveled seeds and impurities and good seeds, the shriveled seeds and impurities float on the water surface, while the good seeds sink to the bottom of the water body. The staff can just pick up and remove the shriveled seeds and impurities on the water surface. This The dry seed selection method is not conducive to long-term storage because good seeds are affected by water immersion and need to be planted and used as soon as possible, otherwise the good seeds will germinate and be damaged. When dry seed selection equipment is used to sort wheat seeds, it drives the wheat seeds to shake through a vibrating screening mechanism. The shriveled seeds and impurities in the wheat seeds are lighter in weight, so during the shaking process, the lighter shriveled seeds and impurities will gather on the surface of the good seeds. The staff can remove the shriveled seeds and impurities on the surface. However, this seed selection method requires manual removal of shriveled seeds and impurities, which makes the seed selection process time-consuming and labor-intensive. At the same time, when manually removing shriveled seeds and impurities, it is easy to take too much or too little, resulting in unsatisfactory seed selection results. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a wheat seed sorting device.

[0043] See also Figure 1 , Figure 2 as well as Figure 3The present embodiment provides a wheat seed sorting device, including a support platform 10, an elastic support layer 20, a receiving component 30, a first driving component 40 and a second driving component 50. The support platform 10 is provided with a through opening, and the elastic support layer 20 is arranged inside the through opening to provide support for the wheat seeds to be sorted. The second driving component 50 is arranged below the elastic support layer 20 to pull the center position of the elastic support layer 20 up and down to repeatedly throw up the wheat seeds to be sorted. The receiving component 30 is arranged above the support platform 10, and the first driving component 40 is installed at the bottom of the support platform 10 to drive the receiving component 30 to rotate. When the receiving component 30 rotates, it receives the lighter impurities thrown out from the wheat seeds.

[0044] Initially, the elastic support layer 20 is located inside the through hole and remains flat. When wheat seed selection is required, the wheat seeds to be selected can be placed on the upper part of the elastic support layer 20, and then the center position of the elastic support layer 20 is pulled by the second driving component 50 to move the center position of the elastic support layer 20 downward, and the first driving component 40 is used to drive the receiving component 30 to rotate. When the center position of the elastic support layer moves downward, it can be deformed to form a funnel-shaped structure, and the wheat seeds located on the upper part of the elastic support layer 20 slide to the bottom of the inner side of the funnel-shaped elastic support layer 20 by themselves. , to achieve the gathering of wheat seeds. After the wheat seeds are gathered, the second driving component 50 drives the center position of the elastic supporting layer 20 to move upward, so that the elastic supporting layer 20 is flattened again. In this process, the elastic supporting layer 20 throws the gathered wheat seeds upward. When the wheat seeds are thrown up to a certain height, they fall down. At this time, the impurities in the wheat seeds are lighter in weight, so the impurities are located above the wheat seeds and are layered with the wheat seeds. The layered impurities are received by the receiving component 30 rotating from above the elastic supporting layer 20, thereby achieving separation between the wheat seeds and the impurities.

[0045] See also Figure 1 as well as Figure 2 In one embodiment, the first driving component 40 includes a driving motor 401, a driving shaft 402, a first gear 403 and a second gear 404. The driving motor 401 is fixedly mounted on the bottom wall of the support platform 10. The first gear 403 is arranged at the output end of the driving motor 401. The driving shaft 402 vertically penetrates the support platform 10 and rotates with the support platform 10. The second gear 404 is fixedly mounted at the bottom of the driving shaft 402 and meshes with the first gear 403. The receiving component 30 includes an impurity receiving box 301. One end of the impurity receiving box 301 is open and the other end is closed. The impurity receiving box 301 is arranged above the support platform 10, and the impurity receiving box 301 is installed on the side wall of the driving shaft 402.

[0046] When the second driving component 50 drives the center position of the elastic supporting layer 20 to move upward so that the elastic supporting layer 20 throws up the wheat seeds thereon, the first gear 403 is driven to rotate by the driving motor 401, and the meshing action between the first gear 403 and the second gear 404 is utilized to drive the driving shaft 402 to rotate. When the driving shaft 402 rotates, it drives the impurity receiving box 301 to rotate, so that the impurity receiving box 301 rotates over the elastic supporting layer 20. At this time, the impurity receiving box 301 cuts into between the layered impurities and the wheat seeds, and the impurities enter the interior of the impurity receiving box 301 through the opening at one end of the impurity receiving box 301, thereby receiving the impurities and separating the impurities from the wheat seeds.

[0047] See also Figure 1 as well as Figure 5 In one embodiment, one end of the impurity receiving box 301 is connected to the side wall of the driving shaft 402 through a support rod 303, and a plurality of second through holes 302 are formed on the end of the impurity receiving box 301 away from the opening.

[0048] When the driving motor 401 drives the first gear 403 to rotate and then drives the driving shaft 402 to rotate through the meshing action of the first gear 403 and the second gear 404, the driving shaft 402 can drive the impurity receiving box 301 to rotate through the support rod 303, so that the impurity receiving box 301 rotates over the elastic support layer 20 to receive impurities, and in the impurity receiving process, since a plurality of second through holes 302 are provided at the end of the impurity receiving box 301 away from the opening, the impurity receiving box 301 will not cause a large disturbance of the air flow during its rotation, but the air on the side of the impurity receiving box 301 facing the rotation direction can pass through the plurality of second through holes 302, and then the impurities are smoothly brought into the interior of the impurity receiving box 301, thereby improving the impurity receiving effect.

[0049] In another embodiment, a filter screen may be embedded in the end of the impurity receiving box 301 away from the opening, so that when the impurity receiving box 301 rotates, the air on the side facing the rotation direction passes through the filter screen and passes through the impurity receiving box 301, thereby achieving smooth reception of impurities.

[0050] See also Figure 2 as well as Figure 4 In one embodiment, the second driving assembly 50 includes an L-shaped connecting rod 503 and an inclined pressure plate 507, one end of the L-shaped connecting rod 503 is connected to the bottom center position of the elastic support layer 20, and the other end passes through the support platform 10 from bottom to top and is fixedly connected to the inclined pressure plate 507, and the inclined pressure plate 507 is arranged on the rotation path of the support rod 303.

[0051] When the driving motor 401 drives the first gear 403 to rotate and then drives the driving shaft 402 to rotate, the driving shaft 402 drives the impurity receiving box 301 to rotate through the support rod 303. When the support rod 303 rotates to the upper part of the inclined pressure plate 507, the support rod 303 acts on the upper surface of the inclined pressure plate 507, thereby pushing the inclined pressure plate 507 to move downward, and the inclined pressure plate 507 drives the L-shaped connecting rod 503 to move downward. When the L-shaped connecting rod 503 moves downward, it pulls the center position of the elastic supporting layer 20, so that the center position of the elastic supporting layer 20 is deformed downward to form a funnel-shaped structure. The wheat seeds on the upper part of the elastic supporting layer 20 slide toward the inner bottom of the funnel-shaped elastic supporting layer 20 by themselves, so as to achieve the gathering of the wheat seeds. After the wheat seeds are gathered, the support rod 303 slides off from one end of the inclined pressure plate 507. At this time, the elastic supporting layer 20 is reset by its own reset action. The center position of the layer 20 moves upward, and then the wheat seeds gathered thereon are thrown up. At the same time, the elastic supporting layer 20 pulls the L-shaped connecting rod 503 and then drives the L-shaped connecting rod 503 to move upward. The L-shaped connecting rod 503 drives the inclined pressure plate 507 to move upward, and the inclined pressure plate 507 is reset until the support rod 303 rotates to the upper part of the inclined pressure plate 507 again and presses down on the inclined pressure plate 507 again. The inclined pressure plate 507 and the L-shaped connecting rod 503 move downward again, and then the center position of the elastic supporting layer 20 moves downward again, and the wheat seeds are gathered again. After the wheat seeds are gathered again, the support rod 303 slides off from one end of the inclined pressure plate 507 again, and the elastic supporting layer 20 throws the gathered wheat seeds up again. This reciprocating cycle can realize the continuous throwing of wheat seeds, and cooperate with the cyclic rotation of the impurity receiving box 301 to carry out multiple impurities.

[0052] See also Figure 1 , Figure 2 as well as Figure 6 In one embodiment, the elastic support layer 20 is provided with a plurality of evenly distributed first through holes 201, the second driving assembly 50 further comprises a piston sleeve 501, a piston rod 502, a gas pipeline 504, an elastic member 505 and a piston block 506, the piston sleeve 501 is fixedly arranged at the bottom center of the elastic support layer 20, the piston block 506 is movably arranged inside the piston sleeve 501, one end of the piston rod 502 is fixedly connected to the bottom of the piston block 506, and the other end extends To the bottom of the piston sleeve 501, one end of the elastic member 505 is connected to the piston block 506, and the other end is connected to the inner wall of the piston sleeve 501, which is used to provide elastic support for the piston block 506. The gas pipeline 504 is fixedly arranged on the side wall of the piston sleeve 501 and connected to the inner cavity of the piston sleeve 501. A plurality of gas holes (not shown in the figure) are opened on the side wall of the gas pipeline 504. The end of the L-shaped connecting rod 503 away from the inclined pressure plate 507 is connected to the piston rod 502.

[0053] When the support rod 303 acts on the upper part of the inclined pressure plate 507 and drives the L-shaped connecting rod 503 to move downward, the L-shaped connecting rod 503 pulls the piston rod 502. The piston rod 502 is pulled and then drives the center position of the elastic support layer 20 to move downward through the piston block 506, the elastic member 505 and the piston sleeve 501, so as to gather the wheat seeds. When the piston rod 502 is pulled, the piston block 506 can also be pulled so that the piston block 506 moves downward along the inside of the piston sleeve 501, thereby drawing the outside air from the several air delivery holes on the side wall of the air delivery pipeline 503 into the inside of the piston sleeve 501. When the support rod 303 slides away from one end of the inclined pressure plate 507 and the elastic support layer 20 throws up the wheat seeds on its upper part, the elastic member 505 can push the piston Block 506 causes the piston block 506 to move upward along the inside of the piston sleeve 501, thereby pressurizing the air inside the piston sleeve 501 to the air supply pipe 504, and then outputting it from a plurality of air supply holes on the side wall of the air supply pipe 504. After being output through the plurality of air supply holes, the air passes through the elastic support layer 20 from bottom to top from a plurality of first through holes 201, and passes through the wheat seeds to further blow upward the impurities in the upper layer, so that the impurities floating on the upper layer are further separated from the wheat seeds in the lower layer, thereby facilitating the impurity receiving box 301 to cut in between the impurities and the wheat seeds, so as to improve the impurity receiving effect; and when the air flow passes through the wheat seeds, some impurities mixed between the wheat seeds can also be blown to the upper layer, thereby improving the separation effect between the impurities and the wheat seeds.

[0054] In one embodiment, the elastic member 505 may be a spring or a metal spring, which is not limited here.

[0055] See also Figure 3 In one embodiment, one end of the support rod 303 away from the impurity receiving box 301 is rotatably connected to the driving shaft 402, an impurity collecting box 102 is fixedly provided on the side wall of the support platform 10, and a third driving component 60 is also provided above the support platform 10. When the impurity receiving box 301 rotates away from above the elastic supporting layer 20 and rotates to above the impurity collecting box 102, the third driving component 60 drives the support rod 303 to rotate relative to the driving shaft 402, and then drives the impurity receiving box 301 to rotate relative to the driving shaft 402. When the impurity receiving box 301 rotates, the impurities received inside it are poured into the impurity collecting box 102 through the opening of the impurity receiving box 301, thereby completing the collection of impurities.

[0056] See also Figure 4 as well as Figure 7In one embodiment, a support sleeve 304 is sleeved on the outside of the support rod 303, and the support sleeve 304 is connected to the support rod 303 through an elastic rotating member 305. The third driving assembly 60 includes a third gear 601, an arc-shaped rack 602 and an arc-shaped support plate 603. The arc-shaped support plate 603 is fixedly arranged on the upper part of the support platform 10, the arc-shaped rack 602 is fixedly arranged on the upper end of the arc-shaped support plate 603, and the third gear 601 is fixedly arranged on the outside of the support rod 303.

[0057] When the impurity receiving box 301 rotates to the top of the impurity collecting box 102 along with the driving shaft 402, the third gear 601 on the outside of the support rod 303 corresponding to the impurity receiving box 301 meshes with the arc-shaped rack 602, and the arc-shaped rack 602 drives the third gear 603 to rotate, thereby driving the support rod 303 and the impurity receiving box 301 to rotate compared with the driving shaft 402. When the impurity receiving box 301 rotates, the impurities received inside it are poured into the impurity collecting box 102 through its opening; when the impurities inside the impurity receiving box 301 are poured out, the third gear 601 is disengaged from the arc-shaped rack 602, and the elastic rotating member 305 drives the support rod 303 to rotate in the opposite direction compared with the driving shaft 402, thereby driving the impurity receiving box 301 to rotate in the opposite direction, thereby realizing the resetting of the impurity receiving box 301 to continue to receive subsequent impurities.

[0058] In one embodiment, the elastic rotating member 305 can be a torsion spring or a scroll spring, which is not limited here.

[0059] In one embodiment, the elastic supporting layer 20 is a rubber layer, or a silicone layer, which is not limited here.

[0060] See also Figure 1 In one embodiment, a plurality of supporting legs 101 are fixedly disposed at the bottom of the supporting platform 10 .

[0061] The working principle of the present invention is as follows:

[0062] First, the wheat seeds to be sorted are placed on the upper part of the flattened elastic support layer 20, and then the driving motor 401 is started. The driving motor 401 drives the first gear 403 to rotate, and the driving shaft 402 is driven to rotate by the meshing action of the first gear 403 and the second gear 404. When the driving shaft 402 rotates, it drives the impurity receiving box 301 to rotate through the support rod 303, so that the impurity receiving box 301 rotates from the upper position of the elastic support layer 20. When the support rod 303 rotates to the upper part of the inclined pressure plate 507, pressure is applied to the inclined pressure plate 507 to drive the inclined pressure plate 507 to move downward, and the inclined pressure plate 507 drives the L-shaped connecting rod 503 to move downward. When the L-shaped connecting rod 503 moves downward, on the one hand, the center position of the elastic supporting layer 20 is driven downward through the piston rod 502, the piston block 506, the elastic member 505 and the piston sleeve 501 to realize the automatic gathering of the wheat seeds thereon, and on the other hand, it directly drives the piston The block 506 moves downward along the inside of the piston sleeve 501 to draw external air from the several air delivery holes on the air delivery pipe 504 into the inside of the piston sleeve 501 to complete the air extraction action; when the support rod 303 slides off from the upper part of the inclined pressure plate 507, the center position of the elastic support layer 20 moves upward and then flattens again to throw the wheat seeds gathered thereon upward, and at the same time, the elastic member 505 pushes the piston block 506 to make the piston block 506 move upward along the inside of the piston sleeve 501 to press the air inside it into the inside of the air delivery pipe 504, and then press it out from the several air delivery holes. The pressed air passes through the elastic support layer 20 from the several first through holes 201 from bottom to top, and then passes through the inside of the thrown wheat seeds to further blow up the impurities in the upper layer, so that the impurities are further separated from the wheat seeds, so that the impurity receiving box 301 can smoothly cut in between the impurities and the wheat planting, and realize the smooth acceptance of the wheat seeds.

[0063] In the embodiment of the present invention, initially, the elastic support layer 20 is located inside the through hole and remains flat. When wheat seed selection is required, the wheat seeds to be selected can be placed on the upper part of the elastic support layer 20, and then the center position of the elastic support layer 20 is pulled by the second driving component 50 to move the center position of the elastic support layer 20 downward, and the first driving component 40 is used to drive the receiving component 30 to rotate. When the center position of the elastic support layer moves downward, it can be deformed to form a funnel-shaped structure. The wheat seeds located on the upper part of the elastic support layer 20 slide to the inner bottom of the funnel-shaped elastic support layer 20 by themselves, so that the wheat seeds are gathered together. After the gathering is completed, the second driving component 50 drives the center position of the elastic supporting layer 20 to move upward, so that the elastic supporting layer 20 is flattened again. In this process, the elastic supporting layer 20 throws the gathered wheat seeds upward. When the wheat seeds are thrown up to a certain height, they fall down. At this time, the impurities in the wheat seeds are lighter in weight, so the impurities are located above the wheat seeds and are layered with the wheat seeds. The layered impurities are received by the receiving component 30 rotating from above the elastic supporting layer 20, thereby realizing the separation between the wheat seeds and the impurities. Compared with the prior art, it can realize automatic sorting of wheat seeds, and has the advantages of good sorting effect and high sorting efficiency.

[0064] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any reference numerals in the claims should not be regarded as limiting the claims involved.

[0065] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
