[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-6 The present invention provides the following technical solution: a cylindrical primary cleaning screen for grain processing, including a device base 1, a screening mechanism 5 rotatably arranged on the top of the device base 1, side baffles 2 arranged on both sides of the bottom of the screening mechanism 5, an exhaust mechanism 3 fixedly installed on one side of the screening mechanism 5, a feeding component 4 fixedly installed on the exhaust mechanism 3, and a cleaning component 6 arranged on the top of the screening mechanism 5.

[0026] The feeding assembly 4 includes a mounting pipe 43, which is installed on top of the exhaust mechanism 3. A feed hopper 41 is fixedly installed on the top of the mounting pipe 43. A motor 46 is installed on one side surface of the mounting pipe 43. A drive shaft 45 is fixedly connected to the output end of the motor 46. A drive roller 44 is fixedly connected to the outer surface of the drive shaft 45. A bearing 42 is installed on the inner side of the mounting pipe 43.

[0027] By adopting the above technical solution, when using the feeding component 4, the grain is first poured into the feeding hopper 41, the motor 46 is started, and the motor 46 drives the transmission shaft 45 and the drive roller 44 to rotate. The arc groove on the surface of the drive roller 44 can control the falling speed of the grain to avoid falling too fast and affecting the exhaust mechanism 3 to remove impurities. The bearing 42 can limit the transmission shaft 45, making the transmission shaft 45 more stable and smooth when rotating.

[0028] Specifically, the top of the feed hopper 41 is movably equipped with a cover plate, and the surface of the drive roller 44 is provided with an arc-shaped groove.

[0029] By adopting the above technical solution, the cover plate facilitates the closing of the feed hopper 41, preventing impurities from being discharged upwards and affecting the operator's operation. The arc-shaped groove enables the grain to be fed evenly, thus improving the feeding function of the device.

[0030] In this embodiment, when using the feeding assembly 4, the grain is first poured into the feeding hopper 41, and the motor 46 is started. The motor 46 drives the transmission shaft 45 and the drive roller 44 to rotate. The arc-shaped groove on the surface of the drive roller 44 can control the falling speed of the grain to prevent it from falling too fast and affecting the exhaust mechanism 3 for removing impurities. The bearing 42 can limit the transmission shaft 45, making the transmission shaft 45 more stable and smooth when rotating. The cover plate can easily cover the feeding hopper 41 to prevent impurities from being discharged upwards and affecting the operator's operation. The arc-shaped groove can evenly feed the grain, thus improving the feeding function of the device.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that, specifically, the cleaning component 6 includes a support frame 62, which is fixedly installed on the top surface of the device base 1. A fixing plate 61 is fixedly connected to the bottom of the support frame 62. A cylinder 63 is installed on the top surface of the support frame 62. A bearing plate 64 is provided at the output end of the cylinder 63. A cleaning brush 65 is fixedly installed inside the bearing plate 64. A dust removal component 66 is installed on one side of the cleaning brush 65.

[0033] By adopting the above technical solution, when using the cleaning component 6, the cylinder 63 is activated, which pushes the support plate 64 and the cleaning brush 65 downward until the cleaning brush 65 contacts the drum. As the drum rolls, it continuously contacts the cleaning brush 65. The cleaning brush 65 can clean the filter holes on the surface of the drum, preventing impurities from clogging the filter holes and affecting the screening efficiency, thus improving the cleaning function of the device.

[0034] Specifically, a bearing groove is provided on the bottom surface of the bearing plate 64, and a bidirectional screw is rotatably installed inside the bearing groove. A clamping plate is threaded onto the surface of the bidirectional screw.

[0035] By adopting the above technical solution, when it is necessary to replace the cleaning brush 65, the knob can be turned to drive the bidirectional screw to rotate, which will further drive the clamps to move away from each other, thereby removing the cleaning brush 65 for replacement and cleaning. The installation can be completed by reversing the operation, which improves the work efficiency of replacing the cleaning brush 65.

[0036] Specifically, the dust removal assembly 66 includes a filter box 661, which is installed on one side surface of the support frame 62. A fixing block 662 is fixedly connected to one side surface of the filter box 661. An air pump 663 is installed on the top of the fixing block 662. An air inlet plate 665 is fixedly installed on one side of the air pump 663. An air guide pipe 664 connects the air inlet plate 665 and the air pump 663.

[0037] By adopting the above technical solution, when the cleaning brush 65 is in continuous contact with the roller, a large amount of dust will float around the roller. At this time, the air pump 663 is started. Under the action of the air pump 663, the external dust enters the filter box 661 through the air inlet plate 665 and the air guide pipe 664. After being filtered by the filter box 661, the air is discharged from the filter box 661, thereby avoiding unnecessary harm to the operator's body caused by dust.

[0038] Specifically, the filter box 661 includes a perforated plate 6611, which is disposed inside the filter box 661. A support block 6613 is fixedly disposed at the bottom of the perforated plate 6611, and a filter screen 6612 is disposed at the bottom of the perforated plate 6611.

[0039] By adopting the above technical solution, the perforated plate 6611 filters larger impurities, while the filter screen 6612 filters smaller dust and impurities. This dual filtration ensures the filtration effect of the filter box 661 and enhances its practicality.

[0040] Specifically, the outer surface of the filter box 661 is provided with a door that can be opened and closed, and an air outlet is provided inside the door.

[0041] By adopting the above technical solution, the filter material can be easily replaced and cleaned by the staff through the door, and the filtered air is discharged from the inside of the filter box 661 through the air outlet, thereby ensuring the stable pressure inside the filter box 661.

[0042] In this embodiment, when using the cleaning component 6, the cylinder 63 is activated, which pushes the support plate 64 and the cleaning brush 65 downwards until the cleaning brush 65 contacts the drum. As the drum rotates, it continuously contacts the cleaning brush 65, which cleans the filter holes on the drum surface, preventing impurities from clogging the filter holes and affecting screening efficiency. This improves the cleaning function of the device. When the cleaning brush 65 needs to be replaced, the knob can be turned to rotate the bidirectional screw, further moving the clamping plates away from each other, thus removing the cleaning brush 65 for replacement and cleaning. The reverse operation completes the installation, improving the efficiency of replacing the cleaning brush 65. As the cleaning brush 65 continuously contacts the drum, the area around the drum... A large amount of dust will float in the air. At this time, the air pump 663 is started. Under the action of the air pump 663, the external dust enters the filter box 661 through the air inlet plate 665 and the air guide pipe 664. After being filtered by the filter box 661, the air is discharged from the filter box 661, thus avoiding unnecessary harm to the operator's body from the dust. The perforated plate 6611 filters larger impurities, and the filter screen 6612 filters smaller dust and impurities. The dual filtration ensures the filtration effect of the filter box 661 and enhances its practicality. The door makes it easy for the staff to replace and clean the filter material. The filtered air is discharged from the filter box 661 through the air outlet, thus ensuring the stability of the pressure inside the filter box 661.

[0043] The structure and operating principle of the device base 1, side baffle 2, exhaust mechanism 3 and screening mechanism 5 in this utility model have been disclosed in a cylindrical primary cleaning screen for grain processing disclosed in Chinese patent application number 202323244385.X.

[0044] The working principle and usage process of this utility model are as follows: When using the feeding component 4, the grain is first poured into the feeding hopper 41. The motor 46 is started, which drives the transmission shaft 45 and the drive roller 44 to rotate. The arc-shaped groove on the surface of the drive roller 44 can control the falling speed of the grain, preventing it from falling too fast and affecting the exhaust mechanism 3 for removing impurities. The bearing 42 can limit the transmission shaft 45, making the transmission shaft 45 more stable and smooth when rotating. The cover plate facilitates the closing of the feeding hopper 41, preventing impurities from being discharged upwards and affecting the operator's operation. The arc-shaped groove can evenly feed the grain, improving the feeding function of the device. When using the cleaning component 6, the cylinder 63 is started, which pushes the bearing plate 64 and the cleaning brush 65 downwards until the cleaning brush 65 contacts the drum. As the drum rolls, it continuously contacts the cleaning brush 65. The cleaning brush 65 can clean the filter holes on the surface of the drum, preventing impurities from clogging the filter holes and affecting the screening efficiency, thus improving the cleaning function of the device. When replacing the cleaning brush 65, the knob can be turned to rotate the bidirectional screw, further moving the clamps apart, thereby removing the cleaning brush 65 for replacement and cleaning. The reverse operation completes the installation, improving the efficiency of replacing the cleaning brush 65. When the cleaning brush 65 is in continuous contact with the roller, a large amount of dust will float around the roller. At this time, the air pump 663 is started. Under the action of the air pump 663, the external dust enters the filter box 661 through the air inlet plate 665 and the air guide pipe 664. After being filtered by the filter box 661, the air is discharged from the filter box 661, thus avoiding unnecessary harm to the operator's body from dust. The perforated plate 6611 filters larger impurities, and the filter screen 6612 filters smaller dust and impurities. The dual filtration ensures the filtration effect of the filter box 661 and enhances its practicality. The door makes it easy for the staff to replace and clean the filter material. The filtered air is discharged from the filter box 661 through the air outlet, thus ensuring the stability of the internal pressure of the filter box 661.
