Description

Technical Field

[0001] This invention belongs to the field of agricultural equipment technology, specifically relating to a seed cleaning device for breeding. Background Technology

[0002] Agriculture, as the foundation of national economic construction and development, has seen its production scale and quality continuously improve with the development and innovation of production equipment. In particular, in response to people's growing demand for high-quality agricultural products, agricultural production activities must not only ensure the production needs of the people's lives but also meet the needs of high-quality consumption.

[0003] To achieve high quality and high yield, pre-treatment of seeds before planting is crucial. Currently, the most common pre-treatment is seed coating. This coating ensures the seeds meet their nutritional needs and protects their appearance during planting. However, to ensure complete and effective coating, dust and impurities in large seed piles often need to be removed. Current impurity removal equipment typically only performs a simple one-time treatment of impurities in the seed pile, which is ineffective and struggles to disperse and remove clumps of seeds, failing to meet production needs. Summary of the Invention

[0004] The purpose of this invention is to provide a seed cleaning device that can effectively remove dust and impurities from seed piles, while preventing seeds from clumping together and affecting subsequent production or cleaning processes.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A seed purification device includes an outer casing, a purification cylinder, a first motor, and a control panel. The first motor is fixedly connected to the other end of the outer casing via a bracket and is drivenly connected to the purification cylinder. The purification cylinder includes a fixed cylinder and a rotating cylinder that are rotatably connected to each other and both connected to the outer casing. A plurality of purification mechanisms are evenly provided at the bottom of the rotating cylinder.

[0007] The impurity removal mechanism includes a hollow tube, a ring gear, and a closed ring. The hollow tube is rotatably mounted at the bottom of the rotating cylinder and extends out of the cylinder. The outer side of the hollow tube is evenly provided with several impurity removal through holes. The ring gear is fixedly mounted on the outside of the hollow tube and located outside the rotating cylinder. The outer casing is fixedly provided with an internal gear ring that meshes with the ring gear. The closed ring includes an annular base plate and a U-shaped cover. The U-shaped cover is fixedly connected to the bracket. The hollow tube extends into the opening of the U-shaped cover. The annular base plate is rotatably connected to the opening end of the U-shaped cover and rotatably connected to the hollow tube. The lower side of the U-shaped cover is provided with a suction pipe that communicates with an external suction mechanism.

[0008] The hollow tube is provided with a switching assembly on one side inside the U-shaped cover. The switching assembly includes a force-bearing plate, a blocking block, a circular plate, and two expansion joints. The circular plate is rotatably sealed on the bottom plate and connected to the hollow tube. The two expansion joints are symmetrically arranged on the ring gear. The force-bearing plate is connected to the two expansion joints. The blocking block is connected to the force-bearing plate and matches the hollow tube. A boss matching the force-bearing plate is provided at the highest horizontal point of the end of the U-shaped cover away from the rotating cylinder. Both ends of the boss are chamfered. A second slag removal assembly matching the hollow tube is provided inside the fixed cylinder.

[0009] The telescopic device includes a limiting plate, a connecting rod, and a spring. The ring gear has a stepped cavity with an opening facing the force-bearing plate. The spring is fixedly disposed in the stepped cavity. The limiting plate is slidably disposed in the stepped cavity and connected to the spring. The connecting rod is fixedly connected to the limiting plate and extends out of the stepped cavity to connect with the force-bearing plate.

[0010] The second slag removal component includes two arc-shaped plates, the two arc-shaped plates are matched with the movement trajectory of several hollow tubes, there is a gap between the two arc-shaped plates, and a rubber sheet is provided between the openings of the two arc-shaped plates. The outer casing is provided with an outer cover that matches the two arc-shaped plates, and the outer cover is connected to the external suction mechanism.

[0011] The arc-shaped plate with a lower horizontal height is provided with an electrically controlled guide rail along its length. The electrically controlled guide rail is connected to a push plate that matches the arc-shaped plate. Several hollow tubes are also provided with circular baffles that match two of the arc-shaped plates.

[0012] The outer casing is equipped with a second motor on its upper side. The output shaft of the second motor is connected to a transmission gear. The outer side of the rotating cylinder is equipped with a transmission gear ring that meshes with the transmission gear. The bottom wall of the rotating cylinder is composed of a rotatable base plate.

[0013] The present invention has at least the following advantages compared to the prior art:

[0014] By combining the impurity removal cylinder and the impurity removal mechanism, the removal of impurities from the seeds can be carried out in a sealed environment with good results. It can continuously and repeatedly clean and remove impurities from the seeds, better meeting the needs of breeding and preventing dust and impurities from affecting subsequent seed coating processing. The impurity removal mechanism can rotate synchronously with the rotating cylinder, and the hollow tube itself can rotate, which can improve the turning effect of the seeds and more effectively remove impurities from the seeds. At the same time, it can turn the seed pile and prevent some clumps of seeds from affecting subsequent processing needs. The setting of the on / off component and the second slag removal component can further improve the cleaning effect of impurities in the seed pile. Attached Figure Description

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Example 1:

[0030] like Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 8 As shown, a seed cleaning device includes an outer casing 1, a cleaning cylinder, a first motor 11, and a control panel. The first motor 11 is fixedly connected to the other end of the outer casing 1 via a bracket 12 and is connected to the cleaning cylinder via a transmission connection. The cleaning cylinder includes a fixed cylinder 2 and a rotating cylinder 21 that are rotatably connected to each other and both connected to the outer casing 1. Several cleaning mechanisms are evenly provided at the bottom of the rotating cylinder 21.

[0031] The impurity removal mechanism includes a hollow tube 3, a ring gear 31, and a closed ring. The hollow tube 3 is rotatably mounted at the bottom of the rotating cylinder 21 and extends out of the rotating cylinder 21. Several impurity removal through holes are evenly provided on the outer side of the hollow tube 3. The ring gear 31 is fixedly mounted on the outside of the hollow tube 3 and located on the outside of the rotating cylinder 21. An inner toothed ring 32 that meshes with and matches the ring gear 31 is fixedly provided on the outer box 1. The closed ring includes an annular base plate 33 and a U-shaped cover 34. The U-shaped cover 34 is fixedly connected to the bracket 12. The hollow tube 3 extends into the opening of the U-shaped cover 34. The annular base plate 33 is rotatably connected to the opening end of the U-shaped cover 34 and is rotatably connected to the hollow tube 3. A suction pipe 35 communicating with an external suction mechanism is provided on the lower side of the U-shaped cover 34.

[0032] When removing impurities from the seeds, open the door on one side of the outer box 1 that is connected to the fixed cylinder 2. At this time, pour the seeds to be removed into the impurity removal cylinder for preparation. After the seeds are put in, the first motor 11 can be turned on through the control panel. Since the first motor 11 is fixedly connected to the outer box 1 and the first motor 11 is driven by the rotating cylinder 21, and since the fixed cylinder 2 and the rotating cylinder 21 are rotatably connected, the fixed cylinder 2 is fixedly connected to the outer box 1 and the rotating cylinder 21 is rotatably connected to the outer box 1, when the rotating cylinder 21 is driven by the first motor 11, the rotating cylinder 21 will rotate, thereby causing the seeds in the rotating cylinder 21 to turn over. When the rotating cylinder 21 rotates, it will also drive several impurity removal mechanisms to operate synchronously and clean the impurities in the seeds in the rotating cylinder 21.

[0033] During the rotation of the rotary drum 21, the external suction mechanism will suction the closed ring through the suction pipe 35. Because the hollow tubes 3 of several impurity removal mechanisms rotate and seal deep into the closed ring, and the bottom plate of the closed ring can rotate with the rotary drum 21 while maintaining the overall sealing environment of the closed ring, the hollow tubes 3 will also simultaneously generate negative pressure suction when the closed ring is subjected to suction from the external suction mechanism. Simultaneously, as the impurity removal mechanism rotates with the rotary drum 21, the seeds inside the rotary drum 21 will be turned over due to gravity, causing dust, debris, and other impurities in the seed pile to be turned over and lifted. At this time, the hollow tubes 3 will penetrate deeper into the seed pile as the rotary drum 21 rotates, thus suctioning and discharging dust, debris, and other impurities from the seed pile into the closed ring, and finally extracting them through the external suction mechanism. It can effectively remove dust, debris and other impurities from seeds in a sealed environment, which is more conducive to the later seed coating operation and avoids dust and debris affecting the seed coating process and causing insufficient nutrition during later planting. Furthermore, since the hollow tube 3 is affected by the ring gear 31 and the internal toothed ring 32, and the internal toothed ring 32 is fixed to the outer box 1, when the hollow tube 3 rotates with the rotating cylinder 21, the ring gear 31 will be rotated by the internal toothed ring 32, and the rotation direction is opposite to the rotation direction of the rotating cylinder 21. In this way, when the hollow tube 3 sucks out the impurities in the seed pile, it can not only more effectively turn the seeds, but also reduce the situation of seeds clogging the impurity removal holes on the outside of the hollow tube 3 through friction between multiple seeds during the rotation of the hollow tube 3.

[0034] Furthermore, through the combination of the impurity removal mechanism and the rotary drum, the seed pile can be effectively separated, preventing some clumps of seeds from affecting subsequent production needs.

[0035] Example 2:

[0036] like Figure 4 , Figure 6 , Figure 9 , Figure 11As shown, in a further improvement based on Embodiment 1, the hollow tube 3 is provided with a switching assembly on one side inside the U-shaped cover 34. The switching assembly includes a force-bearing plate 4, a blocking block 41, a circular plate 42, and two expansion joints. The circular plate 42 is rotatably sealed on the bottom plate and connected to the hollow tube 3. The two expansion joints are symmetrically arranged on the ring gear 31. The force-bearing plate 4 is connected to the two expansion joints. The blocking block 41 is connected to the force-bearing plate 4 and matches the hollow tube 3. A boss 54 matching the force-bearing plate 4 is provided at the highest horizontal point of the end away from the rotating cylinder 21 inside the U-shaped cover 34. Both ends of the boss 54 are chamfered. A second slag removal assembly matching the hollow tube 3 is provided inside the fixed cylinder 2. The expansion joint includes a limiting plate 5, a connecting rod 51, and a spring 52. The ring gear 31 has a step with an opening facing the force-bearing plate 4. The spring 52 is fixedly installed in the stepped cavity 53. The limiting plate 5 is slidably installed in the stepped cavity 53 and connected to the spring 52. The connecting rod 51 is fixedly connected to the limiting plate 5 and extends out of the stepped cavity 53 to connect with the force plate 4. The second slag removal assembly includes two arc-shaped plates 6, which match the movement trajectory of several hollow tubes 3. There is a gap between the two arc-shaped plates 6, and a rubber sheet 61 is provided between the openings of the two arc-shaped plates 6. The outer casing 1 is provided with an outer cover 62 that matches the two arc-shaped plates 6. The outer cover 62 is connected to the external suction mechanism. The arc-shaped plate 6 with the lower horizontal height is provided with an electrically controlled guide rail along its length. The electrically controlled guide rail is connected to a push plate 63 that matches the arc-shaped plate 6. Several hollow tubes 3 are also provided with circular baffles that match the two arc-shaped plates 6.

[0037] The switching component, in conjunction with the second slag removal component, can further improve the cleaning effect on impurities in the seed pile. When cleaning dust and impurities in the seed pile inside the rotary drum 21, the hollow tube 3 rotates synchronously with the rotary drum 21. When there are some large impurities in the seed pile of the hollow tube 3, they will be adsorbed on the outside of the hollow tube 3 and gradually carried away from the seed pile, rising relative to the rotary drum 21. When the hollow tube 3 moves to the boss 54, the force plate 4 will be blocked by the boss 54, thus pushing the connecting rod 51 of the telescopic device, thereby compressing the spring 52 through the limiting plate 5. At this time, the force plate 4 is pressed by the boss 54, thus pushing the blocking block 41 to extend into the hollow tube 3. At this time, the hollow tube 3 is blocked by the blocking block 41 and cuts off the adsorption force. Correspondingly, when the hollow tube 3 completely cuts off the adsorption force, the hollow tube 3 is located in the middle of the two arc plates 6, and at this time, it loses adsorption. Impurities on the hollow tube 3 fall off and are stored in the lower arc plate 6. Since the hollow tube 3 is in a rotating state, it can ensure that all impurities on the outside of the hollow tube 3 can be removed. The rubber sheet 61 can block the impurities to a certain extent. In order to prevent the impurities in the arc plate 6 from accumulating too much and falling back into the seed pile, the control panel is activated once every three hollow tubes 3 pass through the second slag removal component. At this time, the electric control guide rail drives the push plate 63 to move, thereby pushing the larger impurities stored on the arc plate 6 to the outer cover 62 side. Finally, they are removed by the external suction mechanism. After the slag is discharged, the push plate 63 is reset. In order to further improve the suction force between the two arc plates 6, the circular baffle on the hollow tube 3 can block the openings at the ends of the two arc plates 6, thereby further improving the suction force in the environment and improving the slag discharge effect.

[0038] Example 3:

[0039] A further improvement based on Embodiment 1 is that a second motor is provided on the upper side of the outer casing 1, the output shaft of the second motor is connected to a transmission gear, a transmission gear ring that meshes with the transmission gear is provided on the outer side of the rotating cylinder 21, and the bottom wall of the rotating cylinder 21 is composed of a rotatable base plate.

[0040] To further improve the screening effect of impurities in the seed pile, the second motor drives the rotating drum 21 in conjunction with the transmission gear and transmission ring, so that the rotating drum 21 rotates in the opposite direction to the first motor 11. The bottom plate drives the slag removal mechanism, so that the rotation direction between the bottom plate and the rotating drum 21 is opposite, thereby further improving the screening effect of the seed pile.

[0041] Example 4:

[0042] A further improvement based on Embodiment 1 is that a semi-circular baffle matching the impurity removal cylinder is detachably fixed to the lower side of the outer box 1. Several screening holes are evenly opened on the outer side of the rotating cylinder 21. In this way, when removing impurities from seeds, the semi-circular baffle can keep the rotating cylinder 21 blocked and shielded. Together with the outer box 1, a sealed environment is formed inside the impurity removal cylinder, which is conducive to the impurity removal mechanism. When necessary, the semi-circular baffle can be removed, so that the lower side of the rotating cylinder 21 is exposed. At this time, with the help of several screening holes, some seeds inside the rotating cylinder 21 that do not meet the breeding size can be screened out, further meeting the requirements for seed screening in breeding and meeting the needs of use.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
