Abstract
Description
Technical Field
[0001] This utility model relates to the field of seed screening technology, and in particular to a seed screening device. Background Technology
[0002] When planting crops, seeds are screened to ensure germination rate. Seed screening is a method of cleaning crop seeds. It involves using seed sieves with different mesh sizes and shapes to remove impurities, chaff, and small seeds, retaining large, plump, and uniform high-quality seeds, thereby improving seed quality.
[0003] Existing seed screening devices can remove impurities such as mud and sand particles from seeds, but they cannot remove seed coats or seeds that are hollow inside with only the outer shell remaining. This results in low seed quality, making it impossible to guarantee that all seeds will be of good quality when sowing, leading to low germination rates and reduced crop yields. Utility Model Content
[0004] This utility model addresses the problems in the prior art by providing a seed screening device, which is achieved through the following technical solution:

A filter cylinder is installed on one side of the inner cavity of the housing. A storage cavity is formed between the outer wall of the filter cylinder and the inner wall of the housing. The feed hopper is disposed on the top side of the filter cylinder near the storage cavity. A blowing structure is installed on the top of the housing, and the blowing structure faces the side of the feed hopper that receives the feed.
[0006] The present invention is further configured such that: the blowing structure includes a fan, an air inlet pipe and a strip-shaped air outlet, the fan is fixedly installed on the top of the outer side of the housing, the air outlet end of the fan is connected to the air inlet pipe, the air inlet pipe passes through the top of the housing and extends into the housing, the air outlet is suspended inside the housing, the air inlet pipe is connected to the air outlet, and the air outlet is set towards the feeding end of the feeding hopper.
[0007] The present invention is further configured such that: a box door is installed on the storage cavity side of the shell, an air outlet is provided on the box door, and a filter screen is installed at the air outlet.
[0008] The present invention is further configured such that: a filter plate and a screening plate are installed sequentially from top to bottom inside the filter cylinder; the bottom wall of the filter cylinder is the bottom wall of the housing; a motor is fixedly installed at the bottom of the housing; a rotating rod is fixedly installed at the output end of the motor; the rotating rod passes through the bottom wall of the housing and extends into the filter cylinder, passing through the screening plate and the filter plate in sequence; multiple anti-clogging structures are installed on both sides of the rotating rod; a discharge cylinder is installed on the bottom wall of the filter cylinder, the screening plate, and the side of the filter plate away from the storage cavity; and a valve is installed at the connection between the discharge cylinder and the housing.
[0009] The present invention is further configured such that: both the filter plate and the screening plate are provided with a plurality of material passage holes, and the diameter of the material passage holes on the filter plate is larger than the diameter of the material passage holes on the screening plate.
[0010] The present invention is further configured such that: the anti-clogging structure includes extension rods and scouring plates; four extension rods are provided and symmetrically arranged along the rotating rod; two extension rods are provided on the top of the filter plate; two extension rods are provided on the top of the screening plate; and multiple scouring plates are provided and fixedly installed at equal intervals at the bottom of the extension rods on both sides.

[0013] In summary, the beneficial technical effects of this utility model are as follows:
[0014] The air-blowing structure blows the seed coat and hollow seed shell into the storage cavity, removing them and improving seed quality. This ensures a high germination rate and increases crop yield. A filter plate and a screening plate filter out stones and screen seeds by size. A scouring plate pushes the seeds to prevent clogging and incomplete filtration or screening. A movable plate ensures that the scouring plate can still push the seeds even when passing over the higher side of the filter or screening plate. Attached Figure Description

[0021] The blowing structure includes a blower 5, an air inlet pipe 6, and a strip-shaped air outlet 7. The blower 5 is fixedly installed on the top of the outer side of the housing 2. The air outlet end of the blower 5 is connected to the air inlet pipe 6. The air inlet pipe 6 passes through the top of the housing 2 and extends into the housing 2. The air outlet 7 is suspended inside the housing 2. The air inlet pipe 6 is connected to the air outlet 7. The air outlet 7 is positioned facing the feeding end of the feeding hopper 1.
[0022] A door 8 is installed on the side of the storage cavity 4 of the housing 2, and an air outlet 9 is provided on the door 8. A filter screen is installed at the air outlet 9.
[0023] The filter cylinder 3 is equipped with a filter plate 10 and a screening plate 11 installed sequentially from top to bottom. The bottom wall of the filter cylinder 3 is the bottom wall of the shell 2. A motor 12 is fixedly installed at the bottom of the shell 2. A rotating rod 13 is fixedly installed at the output end of the motor 12. The rotating rod 13 penetrates the bottom wall of the shell 2 and extends into the filter cylinder 3, penetrating the screening plate 11 and the filter plate 10 in sequence. Multiple anti-clogging structures are installed on both sides of the rotating rod 13. A discharge cylinder 14 is installed on the bottom wall of the filter cylinder 3, the screening plate 11, and the filter plate 10 on the side away from the storage cavity 4. A valve is installed at the connection between the discharge cylinder 14 and the shell 2.
[0024] Both the filter plate 10 and the screening plate 11 are provided with a plurality of material passage holes 15, and the diameter of the material passage holes 15 on the filter plate 10 is larger than the diameter of the material passage holes 15 on the screening plate 11.
[0025] The anti-clogging structure includes extension rods 16 and dispersing plates 17. Four extension rods 16 are provided and symmetrically arranged along the rotating rod 13.

Under the action of the blower 5 and the air outlet 7, the seed coats and empty seeds mixed in with the seeds are blown into the storage chamber 4. The remaining seeds fall onto the filter plate 10 of the filter cylinder 3. The motor 12 is started, and under the action of the motor 12, the rotating rod 13 is rotated, which in turn drives the extension rod 16 to rotate.
