Description

Technical Field

[0001] This utility model relates to the technical field of agricultural planting, specifically to a seed separation device for agricultural planting. Background Technology

[0002] In agricultural production, seed treatment is a crucial step before planting, with seed selection and cleaning directly impacting crop germination rate and growth quality. Traditional seed separation methods rely primarily on manual screening or simple mechanical sieving devices, which suffer from low efficiency, insufficient cleanliness, and potential seed damage. Especially for seeds of varying sizes, moisture content, and impurity levels, traditional equipment often struggles to achieve efficient and precise grading and dust removal.

[0003] Existing seed separation devices typically employ a fixed screen structure, limiting screening efficiency to a single screen aperture size and failing to flexibly adapt to the grading requirements of different seed varieties. Furthermore, the dust and light impurities generated during screening can easily cause secondary pollution, impacting the working environment and the health of operators.

[0004] Although some improved seed separation devices on the market have introduced vibrating screening and negative pressure dust removal technologies, they still have the following shortcomings: Low screening efficiency: Most devices use a single-layer fixed screen, which cannot achieve multi-stage precise screening. Incomplete dust removal: The negative pressure dust collection system has a simple design and poor dust collection effect; Poor adaptability: It is difficult to meet the processing requirements of seeds of different sizes and moisture levels at the same time; Low level of automation: parameters such as screening angle and vibration frequency need to be adjusted manually, making the operation cumbersome. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a seed separation device for agricultural planting, which can solve the following problems: Existing seed separation devices suffer from problems such as low screening efficiency, incomplete dust removal, poor adaptability, and low degree of automation.

[0006] To solve the above-mentioned technical problems, the present invention proposes the following technical solution: A seed separation device for agricultural planting includes a main body, a negative pressure mechanism fixedly connected to the outside of the main body, a first separation component and a second separation component movably connected to the two sides of the inside of the main body, a base fixedly connected to the bottom of the main body, an outlet cavity opened inside the base, a guide seat fixedly connected inside the main body, a collection cover fixedly connected to the top of the guide seat, a first dust removal cover and a second dust removal cover fixedly connected inside the main body, and both the first separation component and the second separation component include a mounting base and a separation sieve plate movably connected, a baffle plate is provided on the surface of the separation sieve plate in the first separation component, and guide plates are fixedly connected to both sides above the guide seat.

[0007] Furthermore, the main body is rectangular and vertically arranged, with the negative pressure mechanism vertically arranged along one side of it, and the negative pressure mechanism, the first dust removal hood, and the second dust removal hood are all connected by pipes.

[0008] Furthermore, the first dust removal hood and the second dust removal hood are arranged vertically along one side of the inner wall of the main body. The first dust removal hood is arranged vertically and located below the first separation component, while the second dust removal hood is arranged horizontally and located below the second separation component.

[0009] Furthermore, the outlet cavity is opened in a conical shape along the inside of the base, and an outlet is also opened on its outer surface.

[0010] Furthermore, the first and second separation components are staggered vertically along the inner walls of the main body on both sides. The mounting base is fixedly connected to the inner wall of the main body, while the separation sieve plate is inclined in an "L" shape. Its surface is covered with a silicone layer. A drive shaft is provided between the horizontal section and the mounting base. A drive motor is provided at the outer end of the drive shaft. The outer end of the separation sieve plate is inclined outward, and its surface is provided with screening holes.

[0011] Furthermore, the separation sieve plate in the first separation assembly has protruding limiting plates on both sides of the baffle corresponding to the baffle. The baffle is rectangular and is movably embedded in the surface of the separation sieve plate in the first separation assembly.

[0012] Furthermore, two sets of guide plates are arranged horizontally downward in an "L" shape and are fixedly connected to both sides of the inner wall of the main body.

[0023] See Figure 1-3 As shown, an agricultural seed separation device includes a main body 1. A negative pressure mechanism 2 is fixedly connected to the outside of the main body 1. A first separation component 3 and a second separation component 4 are movably connected to the two sides inside the main body 1, respectively. A base 5 is fixedly connected to the bottom of the main body 1. An outlet cavity 6 is opened inside the base 5. A guide seat 7 is fixedly connected inside the main body 1. A collection cover 14 is fixedly connected to the top of the guide seat 7. A first dust removal cover 8 and a second dust removal cover 10 are fixedly connected inside the main body 1. The first separation component 3 and the second separation component 4 both include a mounting base 11 and a separation sieve plate 12 that are movably connected. A baffle 13 is provided on the surface of the separation sieve plate 12 in the first separation component 3. Guide plates 9 are fixedly connected to both sides above the guide seat 7.

[0024] In this embodiment, the main body 1 is rectangular and vertically arranged. The negative pressure mechanism 2 is vertically arranged along one side of the main body 1. The negative pressure mechanism 2, the first dust removal hood 8, and the second dust removal hood 10 are all connected by pipes. The first dust removal hood 8 and the second dust removal hood 10 are arranged vertically along one side of the inner wall of the main body 1. The first dust removal hood 8 is vertically arranged and located below the first separation component 3, while the second dust removal hood 10 is horizontally arranged and located below the second separation component 4. Both the first dust removal hood 8 and the second dust removal hood 10 are equipped with filters. The outlet cavity 6 is opened in a conical shape inside the base 5, and its outer surface is also provided with an outlet. The main body 1 provides a stable support structure, ensuring the overall stability of the device's operation and facilitating the layered layout of internal components. It also forms a closed space with components such as the negative pressure mechanism 2 and the base 5, reducing external interference during seed processing. The negative pressure mechanism 2, in conjunction with the first dust removal hood 8 and the second dust removal hood 10, efficiently removes dust and light impurities generated during seed descent, improving the working environment. The base 5 and the outlet cavity 6 collect and export sorted seeds in a centralized manner, avoiding mixing. The guide cavity 6, which is set in a conical chamber, uses gravity to automatically slide the seeds to the guide outlet, facilitating the classification and collection of seeds of different grades.

[0025] When in use, the negative pressure mechanism 2 is connected to the first dust removal hood 8 and the second dust removal hood 10 through pipes respectively. It uses negative pressure suction to suck the dust and debris generated during the screening process into the dust removal system to avoid secondary pollution.

[0026] In this embodiment, the first separation component 3 and the second separation component 4 are staggered vertically along the inner walls of the two sides of the main body 1. The mounting base 11 is fixedly connected to the inner wall of the main body 1. The separation sieve plate 12 is inclined in an "L" shape and its surface is covered with a silicone layer. A drive shaft is provided between the horizontal section and the mounting base 11. A drive motor is provided at the outer end of the drive shaft. The outer end of the separation sieve plate 12 is inclined outward and its surface is provided with screening holes. The two sides of the surface of the separation sieve plate 12 in the first separation component 3 are provided with protruding limiting plates corresponding to the baffles 13. The baffles 13 are rectangular and are movably embedded in the surface of the separation sieve plate 12 in the first separation component 3. The first separation component 3 and the second separation component 4 achieve the effect of grading and screening seeds by size. The separation sieve plate 12 is inclined in an "L" shape and the tilt angle is controlled by the drive motor, which is convenient to adjust according to the needs. The baffles 13 on the surface of the separation sieve plate 12 in the first separation component 3 achieve the effect of sealing and blocking it.

[0027] During use, the user can select two sets of separation sieves from the two sets of separation components, depending on the seed size. Seeds enter the main body 1 and come into contact with the separation sieve 12 in the first separation component 3 for sieving. Larger seeds remain on the separation sieve 12, while seeds of other sizes fall out. During this process, the second separation component 4 remains vertical and unused. For subsequent secondary separation, the first separation component 3, under the control of the drive motor, changes from an inclined state to a vertical unused state, while the second separation component 4, under the control of the drive motor, changes from a vertical unused state to an inclined used state. The user then feeds seeds back into the main body 1, where the separation sieve 12 in the second separation component 4 performs a secondary separation operation. During this process, the user needs to ensure that the baffle 13 is embedded in the surface of the separation sieve 12 in the first separation component 3 to shield it and prevent it from affecting the secondary sieving. In this embodiment, two sets of guide plates 9 are arranged horizontally downward in an "L" shape and are fixedly connected to both sides of the inner wall of the main body 1. They are also located on both sides above the second dust removal hood 10. The guide plates 9 are coated with polytetrafluoroethylene (PTFE). The guide seat 7 is raised as a whole and is set as a conical base with an annular concave surface and an arc-shaped top. The collection hood 14 is set as an arc-shaped cover along the top of the guide seat 7 and is magnetically connected to the guide seat 7. The two ends of the collection hood 14 are closed in the horizontal direction, and an opening and closing cover plate is set on the vertical surface. The surface of the opening and closing cover plate is provided with filter holes. The guide plates 9 are used to guide the seeds during the falling process. The guide seat 7 and the collection hood 14 are used to guide the seeds during the falling process and collect the impurities and debris.

[0028] During use, the seeds fall along the guide plate 9 onto the guide seat 7, and slide down the collection cover 14 into the outlet cavity 6 for export. Impurities and debris are collected in the collection cover 14 through the filter holes on its surface. The annular concave position on the surface of the guide seat 7 increases the export space for the seeds, preventing export blockage. Afterwards, the user will remove the collection cover 14 from the guide seat 7 to clean the debris and impurities inside.

[0029] In this embodiment, a cyclone separator or filter bag is added inside the pipe of the negative pressure mechanism 2 to achieve multi-stage filtration of dust, from large particles to fine dust, and reduce the risk of pipe blockage. A vibrator is installed inside the conical inclined surface of the outlet cavity 6 to prevent moist seeds from sticking together and accumulating. A hot air circulation system, such as a small electric hot air blower, can be added to the main body 1 to facilitate the drying of damp seeds; The above are all existing publicly available technologies, and will not be elaborated further here.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
