Description

Technical Field

[0001] This utility model relates to the technical field of wheat seed screening equipment, and more specifically, to a vibrating screening machine for wheat seed processing. Background Technology

[0002] Existing wheat seed screening equipment relies solely on vibrating motors to drive the screening mesh, which limits the mesh's movement and causes seeds to accumulate on the mesh, thus affecting screening efficiency.

[0003] To address the aforementioned issues, patent document publication number CN221832799U discloses a novel wheat seed selection device, comprising a sorting box, with support legs fixedly connected to the four corners of the bottom of the sorting box, a feed hopper connected to the top of the sorting box, a discharge pipe connected to the bottom of the sorting box, and guide frames fixedly connected to the front and back of the inner wall of the sorting box, with a screening screen slidably connected between the guide frames.

[0004] However, it still has some drawbacks in actual use. For example, the above-mentioned screening device drives the screening screen to reciprocate in the horizontal direction through the transmission component. Although this increases the movement space of the screening screen, the feed hopper is not designed with a guiding structure. Seeds may fall into a certain area of ​​the screening screen, resulting in local accumulation of seeds while other areas of the screening screen are not fully utilized. This is not coordinated with the horizontal reciprocating motion of the screening screen and may reduce the overall screening uniformity. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vibrating screening machine for wheat seed processing, so as to solve the problem that the feed hopper of the prior art lacks a guiding structure and the seeds tend to accumulate in a local position of the screening screen.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vibrating sieve for wheat seed processing, comprising a sieve device body, wherein a feed hopper is provided on the top of the sieve device body, and the vibrating sieve for wheat seed processing further includes...

[0007] A fixed frame is fixedly installed on the side of the feed hopper, and a bidirectional motor is fixedly installed on the side of the fixed frame opposite to the feed hopper;

[0008] A first transmission roller is fixedly connected to the drive shaft of a bidirectional motor on one side. A transmission belt is provided around the first transmission roller. The first transmission roller is connected to a second transmission roller via the transmission belt. A connecting shaft is fixedly connected to the inner ring of both the first and second transmission rollers. The surface of the connecting shaft is rotatably connected to the inner wall of the feed hopper, and a guide plate is fixedly installed on the surface of the connecting shaft. A guide groove is provided on the surface of the guide plate.

[0009] The device also includes a control terminal, an infrared sensor, a mounting base, and an inclined baffle. The control terminal is mounted on the surface of the bidirectional motor. The infrared sensor is fixedly mounted on one side of the transmission roller relative to the connecting shaft. The inclined baffle is fixedly connected to the side of the feed hopper via the mounting base.

[0010] It also includes a dust removal component, which is located at the top of the feed hopper.

[0011] The dust removal assembly includes a connecting cavity, a dust collection hopper, a fixed base, a collection bin, an upper connecting pipe, a lower connecting pipe, and a fan. The dust collection hopper is fixedly connected to one side of the connecting cavity in the width direction. The fixed base is located at the bottom of the connecting cavity, and its surface is fixedly connected to the back of the feeding hopper. The collection bin is detachably installed on the side of the fixed base opposite to the feeding hopper, and its top is detachably installed. The top end of the upper connecting pipe is fixedly connected to the surface of the connecting cavity. The fan is located on the back of the feeding hopper. The bottom end of the lower connecting pipe is fixedly connected to the air outlet of the fan, and its top end is connected to the bottom of the collection bin.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] In the above scheme, when wheat seeds are fed, a bidirectional motor on one side of the fixed frame drives the first transmission roller to rotate, and the transmission belt drives the second transmission roller to rotate synchronously. This causes the two guide plates to deflect in opposite directions. At this time, some wheat seeds can fall onto the screen surface through the channel between the two guide plates, while other seeds are guided to other positions on the screen surface through the guide groove on the downward inclined guide plate. This guides the wheat seeds and prevents them from falling into the same position on the screen. In addition, when the second transmission roller rotates at a certain angle, the infrared light generated by the infrared sensor can be blocked by the inclined baffle. At this time, the infrared sensor can send a signal to the control terminal, which controls the bidirectional motor to drive the first transmission roller to rotate in the opposite direction. This causes the guide groove to deflect synchronously in the opposite direction, realizing the cross swing of the two guide grooves. The cross swing can agitate the wheat seeds in the feed, preventing the seeds from accumulating and causing blockage in the feed hopper, thereby improving the practicality of the device.

[0014] By generating airflow through a fan located at the back of the feed hopper, dust that is thrown back from the top of the feed hopper during the feeding process can be sucked into the dust collection hopper and stored in the collection bin through the connecting cavity, thereby preventing dust from spreading and affecting the surrounding environment and further improving the practicality of the device.
