Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] according to Figure 1-3 This utility model provides a rapeseed dust removal device, including: a feeding chamber 1, a screening chamber 2, a motor 3, and a drive structure 4.

[0020] The feeding chamber 1 is located on the screening chamber 2; the screening chamber 2 is equipped with a material distribution rod 21; there are several material distribution rods 21; the material distribution rods 21 are arranged along the side of the screening chamber 2 closest to the feeding chamber 1 to the other side; a fan 22 is provided on one side of the screening chamber 2, and a dust discharge port 23 is opened on the other side.

[0021] When rapeseed dust removal is required, the rapeseed is fed into the feeding chamber 1 and then conveyed to the screening chamber 2. Several dividing rods 21 are installed in the screening chamber 2, evenly distributed horizontally and vertically. When the rapeseed reaches the dividing rods 21, it is separated. Because there are multiple dividing rods 21, the rapeseed is separated at multiple points, resulting in a more dispersed distribution within the screening chamber 2, rather than a large concentration of rapeseed. The rapeseed falls into the screening chamber 2 and reaches the fan 22, where it blows away dust from the surface of the rapeseed, which is then discharged from the dust outlet 23. In short, the dividing rods 21 in the screening chamber 2 disperse the rapeseed in multiple locations, resulting in a larger overall contact area for the rapeseed when using the fan 22 for dust removal, thus improving the dust removal effect.

[0022] The material distribution rod 21 is arranged on a horizontal plane along one side of the feed chamber 1 to the other; the fan 22 is located at one end of the material distribution rod 21, and the dust discharge port 23 is located at the other end of the material distribution rod 21. The feed chamber 1 includes: a turning chamber 11, a rotating rod 12, and a rotating disk 13; one end of the rotating rod 12 is connected to the turning chamber 11, and the other end is connected to the rotating disk 13; the turning chamber 11 has a screen hole on the side near the screening chamber 2. The feed chamber 1 also includes: a swing rod 14; a drive structure 4 is connected to a motor 3; a center rod 131 is provided on the rotating disk 13; one end of the swing rod 14 is located on the center rod 131, and the other end is connected to the drive structure 4. The drive structure 4 includes: a drive disk 41, a side rod 42, and a drive rod 43; the drive disk 41 is connected to the motor 3; the side rod 42 is located on the drive disk 41; the side rod 42 is located on one side of the center of the drive disk 41; one end of the drive rod 43 is rotatably located on the side rod 42. A drive rod 431 is provided on the side of the drive rod 43 away from the side rod 42; a drive opening 141 is opened on the side of the swing rod 14 away from the center rod 131; the drive opening 141 is rotatably sleeved on the drive rod 431. The feed chamber 1 also includes: a discharge port 15, an inclined plate 16, and a buffer plate 17; the discharge port 15 is located on the side of the feed chamber 1 near the screening chamber 2; the inclined plate 16 is located on both sides of the discharge port 15; the buffer plate 17 is located on the side of the discharge port 15 away from the screening chamber 2.

[0023] When the blower 22 removes dust through air separation, the rapeseed is also slightly agitated. In this invention, the rapeseed falls from top to bottom and settles on both sides of the distribution bar 21. The blower 22 is positioned at one end of the distribution bar 21, and the dust outlet 23 is positioned at the other end. This ensures that when the blower 22 agitates the rapeseed, it does not interfere with the distribution of the rapeseed on both sides of the distribution bar 21, preventing the rapeseed from concentrating and causing some of the air blown by the blower 22 to miss the rapeseed, thus reducing the overall dust removal efficiency. During rapeseed collection, it often contains large impurities such as broken leaves. These impurities are often mixed with dust during collection, making them difficult to separate easily. Furthermore, these impurities are larger than the rapeseed and are not easily separated by air separation. This invention includes a turning chamber 11 in the feeding chamber 1, with sieve holes at the bottom. This allows the rapeseed to pass through while large impurities such as broken leaves cannot, thus screening out the rapeseed and trapping the impurities. This utility model also includes a motor 3 and a drive structure 4. Starting the motor 3 can drive the drive disk 41 to rotate. When the drive disk 41 rotates, it can drive the side rod 42 to rotate. Since the side rod 42 is located on one side of the center of the drive disk 41, the rotation trajectory of the side rod 42 is a circle. When the side rod 42 rotates, it will drive the drive rod 43, which in turn drives the swing rod 14. Since one end of the drive rod 43 is rotatably mounted on the side rod 42, and the drive opening 141 is rotatably sleeved on the drive rod 431, when the drive rod 43 is driven, one end rotates with the side rod 42. The other end of the rotating rod 14 swings repeatedly, causing the central rod 131 to rotate back and forth within a certain range. This causes the rotating disk 13 to rotate back and forth, which in turn causes the rotating rod 12 to rotate, causing the turning chamber 11 to tumble repeatedly. This results in the rapeseed being constantly shaken within the turning chamber 11, allowing it to be sieved. Compared to a typical vibrating screen, the turning chamber 11, through its back-and-forth tumbling motion, allows impurities and rapeseed at the edges to flow actively, preventing some materials from being difficult to sieve. After the rapeseed leaves the turning chamber 11 through the sieve holes, it reaches the buffer plate 17, then slides down from the buffer plate 17 onto the inclined plate 16, and finally slides down from the inclined plate 16 into the screening chamber 2. Since the turning chamber 11 will turn, the screening chamber 2 needs to be a certain distance away from the turning chamber 11 to avoid interference. By setting the buffer plate 17 and the inclined plate 16, the rapeseed will first fall to a support position and then fall into the screening chamber 2, so as to avoid the rapeseed falling from a high place and causing excessive impact force, which would cause the rapeseed to deform or break.

[0024] Working principle and usage process of this utility model:

[0025] When rapeseed dust removal is required, the rapeseed is first fed into the turning chamber 11 inside the feeding chamber 1. Then, the motor 3 is started, which drives the drive disc 41 of the drive structure 4 to rotate. When the drive disc 41 rotates, it drives the side rod 42 to rotate. When the side rod 42 rotates, it drives the drive rod 43. The drive rod 43 then drives the swing rod 14 to swing repeatedly. When the swing rod 14 swings, it drives the central rod 131 to rotate back and forth within a certain range, causing the rotating disc 13 to rotate back and forth. The rotating disc then drives the rotating rod 12 to rotate, causing the turning chamber 11 to also rotate repeatedly, so that the rapeseed is constantly turned back and forth in the turning chamber 11. After the rapeseed leaves the turning chamber 11 through the sieve holes, it reaches the buffer plate 17, and then slides down from the buffer plate 17 onto the inclined plate 16, and then slides down from the inclined plate 16 into the screening chamber 2. When the rapeseed reaches the separating rod 21, it will be separated by several separating rods 21. When the rapeseed falls into the screening chamber 2 and reaches the blower 22, it will be blown by the blower, causing the dust on the surface of the rapeseed to be blown off the surface of the rapeseed and discharged from the dust outlet 23.

[0026] In summary, this utility model has a material distribution rod in the screening chamber, which disperses the rapeseed in multiple places in the screening chamber. When using a fan for dust removal, the overall contact area of ​​the rapeseed is larger, resulting in a better dust removal effect.
