Description

Technical Field

[0001] This utility model relates to the field of seed processing technology, and in particular to a seed processing dust collection device. Background Technology

[0002] Dust removal is a crucial step in seed processing. Traditional methods rely primarily on manual labor, using hand sifting or simple tools to remove impurities and dust from the seed surface. However, this approach has several drawbacks: firstly, manual dust removal is inefficient and cannot meet the demands of large-scale seed processing; secondly, manual operation makes it difficult to guarantee consistent dust removal results, easily leading to omissions or over-processing, resulting in inconsistent seed quality. Furthermore, the airborne dust and impurities during manual dust removal pose potential health hazards to operators and pollute the processing environment.

[0003] While some mechanized seed dust removal equipment exists on the market, most of these devices are complex in structure, expensive, and still need improvement in terms of dust removal efficiency and ease of operation. For example, some equipment only uses simple sieving or air blowing to remove dust, which is ineffective at removing fine dust and impurities adhering to the seed surface. Other equipment, although capable of a certain degree of automation, has design flaws in seed conveying, collection, and dust separation and collection, which can easily lead to seed damage, secondary dust contamination, and other problems, affecting the overall quality and efficiency of seed processing.

[0004] Therefore, developing a seed processing dust collection device that is simple in structure, has good dust removal effect, is easy to operate and has low cost is of great practical significance for improving the quality and efficiency of seed processing, protecting the health of operators and optimizing the processing environment.

[0005] Chinese patent document CN214262728U discloses a corn seed screening device with dust removal function, including a fixed frame installed on the ground with the left side lower than the right side. A primary screening seat, a secondary screening seat, and a collection seat are arranged sequentially from top to bottom on the fixed frame. The primary screening seat, secondary screening seat, and collection seat are fixed together by a connecting frame. This corn seed screening device with dust removal function, by setting a screening mechanism on top of the primary screening seat and setting an elastic mechanism between the fixed frame and the collection seat, utilizes a first motor to provide power output, which is transmitted through a first transmission wheel, a second transmission wheel, and a transmission belt. The rotation of the rotating rod and the convex seat causes uneven force to vibrate the entire screening mechanism. Combined with the first convex block, the second convex block, and the spring, this allows dust on the surface of the corn seeds to be separated from the seeds, achieving a dust removal effect. The device has a novel structure and is easy to use.

[0006] Chinese patent document CN216368793U discloses a seed screening device for agricultural seed engineering with convenient dust removal, including a shell, a screening and collection mechanism, and a dust removal mechanism. The screening and collection mechanism is located inside the shell. The dust removal mechanism is also located inside the shell. The screening mechanism includes support blocks and a collection shell. There are two support blocks, which are respectively installed on the bottom of the left and right sides of the inner wall of the shell. This patent facilitates the collection of screened seeds through the cooperation of support blocks, collection shell, screening screen, locking blocks, locking slots, and pull plates. It also facilitates the disassembly and maintenance of the screening screen, improving practicality. Through the cooperation of a diversion plate, connecting plate, through hole, exhaust fan, connector, fixing pipe, suction head, top plate, water tank, positioning rod, slider, and connecting pipe, it facilitates the dust removal generated during screening, while preventing excessive dust from affecting subsequent seed sowing.

[0007] However, the shortcomings of the two patents mentioned above are: their dust removal efficiency is too low. For large-scale seed dust removal, the simple transmission and separation during transportation cannot completely remove dust and impurities from the seed surface, especially impurities adhering to the seeds. Neither of the aforementioned patents has corresponding methods for effective treatment.

[0008] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art. On the contrary, this utility model has all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

Detailed Implementation

[0024] The following is a detailed explanation with reference to the accompanying drawings.

[0025] Example 1

[0026] This utility model provides a dust collection device for seed processing, such as... Figure 1 As shown, the device includes a main body 100. A feed inlet 101 is provided at the vertical end of the main body 100. A dust removal assembly 200 for removing dust from seeds is correspondingly provided at the vertically downward end of the feed inlet 101. The dust removal assembly 200 includes a first driving member 201, a connecting rod 202 eccentrically connected to the first driving member 201 and freely rotatable, and a dust removal chamber 203 rotatably connected to the connecting rod 202. A rotating rod 204 is provided at the physical center point of the dust removal chamber 203, and both ends of the rotating rod 204 are rotatably connected to the dust removal chamber 203 and the inner wall of the main body 100, respectively. The first driving member 201 can be a disc structure driven by a drive motor. The connecting rod 202 is rotatably connected to the eccentric position of the disc, so that under the drive of the first driving member 201, one end of the connecting rod 202 performs a circular motion around the first driving member 201. Furthermore, the dust collection chamber 203 is fixed to the inner wall of the main body 100 via a rotating rod 204 and can rotate around the rotating rod 204. Since the other end of the connecting rod 202 is rotatably connected to the dust collection chamber 203, under the drive of the first driving member 101, the dust collection chamber 203 can be pulled by the connecting rod 202 to perform a reciprocating swinging motion around the rotating rod 204. Thus, through its mechanical structure design, this invention can reciprocate and vibrate the seeds inside the dust collection chamber 203, effectively removing impurities and dust from the seed surface, reducing manual dust removal operations. The rapid vibration causes the seeds to collide, thereby separating dust and impurities that differ in weight from the seeds.

[0027] According to a preferred embodiment, the end of the connecting rod 202 away from the first driving member 201 is connected to the horizontal left or right end of the dust collection chamber 203. The dust collection chamber 203 is a hollow cuboid or arc-shaped body. Preferably, the physical center of the dust collection chamber 203 can be its geometric center. For example, when the dust collection chamber 203 is a cuboid, its physical center can be the intersection of its diagonals. Further, when the dust collection chamber 203 is a cuboid, its physical center can also be the center of a sphere formed by the four points on the bottom surface of the dust collection chamber 203. When the dust collection chamber 203 is an arc-shaped body, its physical center can be the center of its complete sphere. Thus, the dust collection chamber 203 can rotate around an axis or reciprocate like a pendulum around its center under the rotational connection of the rotating rod 204.

[0028] According to a preferred embodiment, a collection plate 205 for receiving seeds entering from the feed inlet 101 is provided vertically below the dust collection chamber 203. The collection plate 205 serves as the bottom surface of the dust collection chamber 203 and is used to receive seeds entering from the feed inlet 101. Preferably, the collection plate 205 may be provided with holes (not shown in the drawings) to screen out dust or impurities. The diameter of the holes is smaller than the diameter of the seeds.

[0029] According to a preferred embodiment, the dust removal assembly 200 further includes a negative pressure fan 206 for blowing away dust from the dust removal chamber 203. The negative pressure fan 206 is disposed on the inner wall of the main body 100, and the outlet of the negative pressure fan 206 faces the dust removal chamber 203. In this invention, the outlet of the negative pressure fan 206 directly faces the dust removal chamber 203, thereby blowing away airborne dust from the area where the seeds are located while the dust removal chamber 203 shakes or sieves out dust and impurities from the seeds, thus achieving dust removal treatment of the seeds.

[0030] According to a preferred embodiment, the system further includes a dust collection assembly 300 for collecting dust discharged from the dust removal assembly 200. The dust collection assembly 300 includes a dust collection baffle 301 to prevent dust from flying out, an exhaust fan 302 for suction of dust, and a dust collection chamber 303. The dust collection assembly 300 is located inside the main body 100 on the side away from the negative pressure fan 206, thereby collecting dust and impurities blown in by the negative pressure fan 206. The exhaust fan 302 draws dust from the channel formed by the dust collection baffle 301 for collection.

[0031] According to a preferred embodiment, the dust collection baffle 301 is provided with a filter screen to prevent seeds from entering the dust collection assembly 300. A dust cover is provided at the exhaust fan 302. The filter diameter of the filter screen is smaller than the diameter of the seed. A filter screen is provided at the channel formed by the dust collection baffle 301 to prevent seeds from falling into the dust collection assembly 300. The dust cover can prevent collected dust and impurities from affecting the normal operation of the exhaust fan 302.

[0032] According to a preferred embodiment, such as Figure 3 As shown, a second driving member 207 for driving the collection plate 205 to rotate axially is provided at one end of the collection plate 205 near the dust collection assembly 300. The dust collection chamber 203 and the collection plate 205 are movably connected via the second driving member 207. The second driving member 207 can be a drive motor, thereby enabling the collection plate 205 to rotate away from the dust collection chamber 203 under the drive of the second driving member 207. Thus, as Figure 2 As shown, the dust-removed seeds in the dust collection chamber 203 can slide out from the collection plate 205 for subsequent collection processes. Furthermore, the start and stop of the second drive component 207 can be controlled by an operator. More preferably, the start and stop of the second drive component 207 can be timed. After the dust collection chamber 203 has vibrated for a certain period of time, the second drive component 207 releases the vibrated seeds at regular intervals, and when the second drive component 207 returns to its original position, the feed inlet 101 introduces seeds to be dusted.

[0033] According to a preferred embodiment, the dust removal assembly 200 has a collection assembly 400 at its vertical lower end for collecting seeds that slide off the collection plate 205. The collection assembly 400 includes a plurality of guide plates 401 and a collection bin 402 located at the vertical lower end of the main body 100.

[0034] According to a preferred embodiment, a plurality of guide plates 401 are arranged at an angle in a tiered manner on the inner wall of the main body 100. At least two guide plates 401 guide the seeds to fall in an alternating tilting manner, thereby preventing the seeds from falling directly into the collection chamber 402 carrying dust. Moreover, during the rolling descent of the seeds, the dust is also blown out by the negative pressure fan 206, further improving the dust removal efficiency of this device.

[0035] According to a preferred embodiment, a pretreatment chamber 102 for batch seed delivery is further provided between the feed inlet 101 and the dust removal assembly 200. The pretreatment chamber 102 is connected to the feed inlet 101. The delivery port of the pretreatment chamber 102 is connected to the dust removal assembly 200. The pretreatment chamber 102 can pre-store excess seeds placed into the feed inlet 101, so that the next batch of seeds can be delivered after the dust removal assembly 200 has processed the previous batch. Furthermore, a weight sensor is provided inside the pretreatment chamber 102, so that the chamber opening is opened to deliver seeds into the dust removal assembly 200 when the pretreatment chamber 102 is about to be full or when the pretreatment chamber 102 has accumulated enough seeds for the next batch to be processed. In this invention, the delivery port of the pretreatment chamber 102 can be an electrically controlled door, whose opening and closing are controlled by the signal of the weight sensor or by the operator. After the door is opened, the seeds enter the dust removal assembly 200 under the action of gravity.
