[0002] Planting green manure has advantages such as altering soil physical and chemical properties, increasing soil organic matter, and improving crop yield and quality. It is also an important technical means for crop rotation and fallow, improving arable land quality, and reducing the application of chemical fertilizers. Green manure seeds refer to the seeds used for planting green manure crops. There are many types of green manure seeds, each with different growth characteristics and ecological functions.

[0003] In the existing technology, such as the public document with publication number CN215142013U, only the seed size is screened. However, when green manure seeds are collected, weeds and pebbles are mixed in. When the size screening method is used, weeds and pebbles of similar size mixed in with the green manure seeds cannot be separated from the green manure seeds, and the weeds and pebbles mixed in with the green manure seeds cannot be effectively removed. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a green manure seed collection and impurity removal device.

[0031] The collection section includes a collection box 8 disposed on the side of the salt separation box 4. An inclined bucket elevator 9 is installed between the salt separation box 4 and the collection box 8. The higher end of the bucket elevator 9 is located inside the collection box 8, and the lower end of the bucket elevator 9 is located inside the salt separation box 4.

[0032] In this embodiment, a plurality of buffer plates 10 are fixedly connected inside the adding hopper 2. The adjacent buffer plates 10 are staggered. One end of the buffer plate 10 is connected to the inner wall of the adding hopper 2, and the other end extends toward the air classifier 3. The buffer plate 10 can slow down the feeding speed of the seeds and guide the seeds to the side close to the air classifier 3, ensuring that the air blown out by the air classifier 3 can fully act on the seeds.

[0033] In this embodiment, the air separator box 1 has an opening on one side, and a breathable filter box 11 is inserted into the opening. The breathable filter box 11 is arranged opposite to the air separator fan 3. The breathable filter box 11 can collect weeds and ensure that the air blown by the air separator fan 3 can be smoothly discharged into the environment.

[0034] In this embodiment, a baffle 12 is fixedly connected to the side of the air-permeable filter box 11, and a clamp 13 for fixing the baffle 12 is installed on the top of the air separator box 1. The clamp 13 can drive the baffle 12, and the air-permeable filter box 11 is limited by the cooperation of the clamp 13 and the baffle 12.

[0035] In this embodiment, the bucket conveyor belt 6 includes a first conveyor belt 61 installed inside the salt sorting box 4. A first motor 62 is installed on the outer wall of the salt sorting box 4. The output end of the first motor 62 passes through the wall of the salt sorting box 4 and is connected to the first conveyor belt 61. A plurality of first digging buckets 63 are installed on the first conveyor belt 61 at intervals. The first motor 62 drives the first conveyor belt 61 to move the first digging buckets 63 to transfer the stones falling on the first conveyor belt 61 to the stone collection bucket 7.

[0036] In this embodiment, the bucket elevator 9 includes a second conveyor belt 91 installed between the salt selection box 4 and the collection box 8. A second motor 92 is installed on the outer wall of the collection box 8. The output end of the second motor 92 passes through the wall of the collection box 8 and is connected to the second conveyor belt 91. Several second buckets 93 are installed on the second conveyor belt 91 at intervals. The second buckets 93 are made of a mesh plate material with extremely small aperture. The second motor 92 drives the second conveyor belt 91 to move the second buckets 93 to lift and transfer the seeds into the collection box 8. The second buckets 93 are made of a mesh plate material with extremely small aperture, which realizes drainage during the lifting process.

[0037] In this embodiment, an electric push rod 14 is fixedly installed on the side wall of the salt selection box 4. The movable end of the electric push rod 14 extends through the wall of the salt selection box 4 and is fixedly installed with a support seat 15. The stone collection hopper 7 is connected to the support seat 15. The electric push rod 14 pushes the support seat 15 to move the stone collection hopper 7 out from under the bucket conveyor belt 6, making it convenient to take out the stone collection hopper 7.

[0038] In this embodiment, brine is injected into the salt selection box 4. The salt content of the brine is adjusted according to the type of green manure seeds. The brine level is higher than the bottom of the bucket elevator 9. The wind speed of the air classifier fan 3 is adjustable.

[0039] How to use and how to work this device:

[0040] When using this device, first turn on the air classifier 3 and feed the seeds after size screening into the feeding hopper 2 in batches. The buffer plate 10 can slow down the feeding speed of the seeds. The seeds can enter the air classifier box 1 through the feeding hopper 2. There is a continuous airflow blown out by the air classifier 3 in the air classifier box 1. This airflow will generate a lateral force on the seeds discharged from the feeding hopper 2. The heavier seeds and stones that may be carried in during the harvesting process are less affected by the lateral wind force and can continue to maintain a straight-line motion and fall into the transfer hopper 5. The lighter weeds mixed in with the seeds are more affected by the lateral wind force and will drift farther and enter the breathable filter box 11, realizing the separation of weeds in the seeds and effectively removing weeds mixed in with green manure seeds.

[0041] Seeds and pebbles that fall into transfer hopper 5 will enter salt separation box 4. The buoyancy of the prepared brine will separate the seeds and pebbles. The seeds will float on the surface of the liquid, while the heavier pebbles will sink to the first conveyor belt 61. The first conveyor belt 61, together with the first digging bucket 63, will transfer the pebbles towards the pebble collection hopper 7 until they fall into the pebble collection hopper 7 for collection. Meanwhile, the second conveyor belt 91, together with the second digging bucket 93, can lift the seeds floating on the surface of the liquid. The second digging bucket 93 will drain the water as it lifts the seeds. When the second digging bucket 93 moves to the end of the second conveyor belt 91, it will flip over and pour the seeds into the collection box 8, thus separating the seeds and pebbles and effectively removing the pebbles mixed in with the green manure seeds.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
