[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] First embodiment:

[0028] See Figures 1-5As shown, this utility model provides a rapeseed raw material screening device for rapeseed oil processing, including a shell 1. A feed hopper 101 is provided on the top surface of the shell 1. A magnetic conveying device 5 and a rotating assembly 3 for driving the magnetic conveying device 5 are provided inside the shell 1. The rotating assembly 3 drives the magnetic conveying device 5 to perform transmission, thereby assisting in the conveying of rapeseed on the magnetic conveying device 5. The magnetic conveying device 5 is correspondingly positioned at the bottom of the feed hopper 101, and a gap is provided between the feed hopper 101 and the magnetic conveying device 5 to allow the rapeseed to pass through. The bottom surface of the inner shell 1 is provided with a combing device 2 corresponding to the magnetic conveying device 5. A guide cavity 102 is provided between the magnetic conveying device 5 and the shell 1. Inside the shell 1, there is a blower 7 that blows the rapeseed falling from the guide cavity 102. The outer wall of the shell 1 is provided with a connecting pipe 104 corresponding to the blower 7. A cloth bag 6 is provided on the outside of the connecting pipe 104. When the blower 7 is working, the blower 7 blows the rapeseed falling from the guide cavity 102, which can blow lighter impurities into the connecting pipe 104, thereby achieving the screening of rapeseed material.

[0029] When the device is in use, the rapeseed material is guided into the feed hopper 101. The rotating component 3 drives the magnetic conveying device 5 to drive the rapeseed through the gap at the bottom of the feed hopper 101 to the surface of the magnetic conveying device 5. With the transmission of the magnetic conveying device 5, the rapeseed on the surface of the magnetic conveying device 5 can be conveyed. Further, the combing device 2 is used to spread the rapeseed and flatten it. When the rapeseed reaches the guide cavity 102, the rapeseed falls downward. The blower 7 can blow the rapeseed, which can blow the light impurities in the rapeseed into the connecting pipe 104. The cloth bag 6 is used to carry the impurities in the rapeseed to achieve the screening of impurities in the rapeseed. The magnetic conveying device 5 is used to screen iron impurities in the rapeseed during the conveying process, so as to achieve the screening of iron impurities without stopping the machine.

[0030] The second embodiment differs from the first embodiment in that:

[0031] The rotating assembly 3 includes a first roller 301 and a second roller 302, which are rotatably connected to the housing 1. A magnetic conveying device 5 is driven and disposed outside the first roller 301 and the second roller 302. The housing 1 is equipped with a mechanism to drive the first roller 301 or the second roller 302. In the structure of the rotating assembly 3, the first roller 301 drives the first roller 301 or the second roller 302 to rotate, thereby driving the magnetic conveying device 5 to rotate outside the first roller 301 and the second roller 302. The magnetic conveying device 5 is used to convey rapeseed material.

[0032] The magnetic conveying device 5 includes a magnetic conveyor belt 501 and a leather conveyor belt 502. The leather conveyor belt 502 is located outside the magnetic conveyor belt 501. An inner roller shaft 303 is rotatably connected to the housing 1. The inner roller shaft 303 is located inside the magnetic conveyor belt 501, and the magnetic conveyor belt 501 at the bottom passes around the outside of the inner roller shaft 303. An inclined plate 103 is provided inside the housing 1 below the magnetic conveying device 5, and a door corresponding to the lower end of the inclined plate 103 is provided on the housing 1.

[0033] The leather conveyor belt 502 is located outside the magnetic conveyor belt 501. When the rapeseed is conveyed by the magnetic conveying device 5, it can adsorb iron impurities in the rapeseed. When the iron impurities rotate to the bottom, the magnetic conveyor belt 501 passes around the inner roller shaft 303 for transmission, and the magnetic conveyor belt 501 separates from the leather conveyor belt 502. The leather conveyor belt 502 is no longer magnetic, and the iron impurities will fall onto the inclined plate 103, thereby achieving the screening of iron impurities in the rapeseed. Furthermore, the contact surfaces of the magnetic conveyor belt 501 and the leather conveyor belt 502 are provided with matching grooves and protrusions. There are multiple grooves and protrusions to ensure the synchronous transmission of the magnetic conveyor belt 501 and the leather conveyor belt 502.

[0034] In the preferred structure, a guide roller shaft 304 is also included. The guide roller shaft 304 is located on both sides of the inner roller shaft 303 and is used to assist in guiding the magnetic conveyor belt 501. There are two inner roller shafts 303 and two guide roller shafts 304, which are used to guide the magnetic conveyor belt 501 so that the magnetic conveyor belt 501 is driven towards the inner side of the first roller shaft 301 and the inner side of the inner roller shaft 303, thereby assisting the magnetic conveyor belt 501 to drive smoothly.

[0035] The third embodiment differs from the first embodiment in that:

[0036] The cleaning assembly 4 includes a gantry frame 403, which is gantry-shaped and disposed on the outer wall of the housing 1. The housing 1 is provided with a groove corresponding to the magnetic conveying device 5. The first roller shaft 301 is located outside the groove and is rotatably disposed inside the gantry frame 403. The closed end of the gantry frame 403 is connected to a cleaning wiper 402 via a thrust spring 401. The cleaning wiper 402 is in contact with the outer side of the magnetic conveying device 5. When the magnetic conveying device 5 rotates outside the rotating assembly 3, the elasticity of the thrust spring 401 pushes the cleaning wiper 402 toward the magnetic conveying device 5, so that the cleaning wiper 402 is close to the outer wall of the magnetic conveying device 5, and the outer wall of the magnetic conveying device 5 can be cleaned using the cleaning wiper 402.

[0037] The fourth embodiment differs from the first embodiment in that:

[0038] The combing device 2 includes a flat plate 201. The surface of the flat plate 201 facing the magnetic conveying device 5 is provided with a scraper 203 and multiple rows of uprights 202. The bottom ends of the scraper 203 and the uprights 202 are in contact with the surface of the magnetic conveying device 5. Adjacent rows of uprights 202 are spaced apart. The scraper 203 is close to the conveying front end of the magnetic conveying device 5. The flat plate 201 is connected to the inner top surface of the housing 1 through a connecting rod. As the rapeseed is conveyed on the surface of the magnetic conveying device 5, the rapeseed is combed by multiple sets of flat plates 201 to achieve the sorting work of the rapeseed. In conjunction with the scraper 203, the rapeseed is spread evenly, so that after the rapeseed reaches the guide chamber 102, it can be evenly sprinkled downwards to ensure the air separation effect of the blower 7.

[0039] Furthermore, the bottom of the feed hopper 101 has a continuous concave-convex structure, which is used to assist in guiding the rapeseed material in the feed hopper 101 to the surface of the magnetic conveying device 5. The concave-convex structure at the bottom of the feed hopper 101 is used to guide and assist in spreading the rapeseed material.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
