Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to impurity removal equipment with a throwing roller at a fan outlet. Background Art

[0002] When harvesting sugarcane, it will carry a lot of sugarcane leaves and other impurities. Sugarcane leaves need to be removed for processing. The commonly used method is the segmentation method, that is, the harvested sugarcane with leaves is segmented, and both the sugarcane and the sugarcane leaves are cut into segments, forming segments, and the sugarcane leaves are also cut. The cut sugarcane leaves will be separated from the sugarcane, and then the light sugarcane leaves are extracted and removed by negative pressure suction, thereby achieving sugarcane impurity removal. However, at present, when sugarcanes are fed into the winnowing machine, they are stacked on each other, which reduces the winnowing effect and causes the sugarcane leaves to not be completely removed. Utility Model Content

[0003] The utility model aims to provide impurity removal equipment with a throwing roller at a fan port, so as to improve the wind selection effect and the impurity removal rate.

[0004] A kind of impurity removal equipment with a throwing roller at the fan outlet, characterized in that it comprises: a pneumatic separator, the pneumatic separator includes a negative pressure bin and an exhaust fan for providing negative pressure to the negative pressure bin; a conveyor belt; a rotatable throwing roller; wherein the outlet end of the conveyor belt is connected to the negative pressure bin of the fan, the throwing roller is connected to the lower part of the outlet end of the conveyor belt, and the rotation direction of the throwing roller scatters the sugarcane.

[0005] In one embodiment, the throwing roller is located in front of and below the conveyor belt.

[0006] In one embodiment, the conveyor belt is arranged obliquely, and the outlet end of the conveyor belt is higher than the inlet end.

[0007] In one of the embodiments, the outer circumference of the throwing roller is provided with a plurality of ear plates erected relative to the outer circumference.

[0008] In one embodiment, the ear plate is welded to the throwing roller.

[0009] In one of the embodiments, a film is mounted on the ear plate.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1-3 As shown, the impurity removal device with a throwing roller 30 at the blower outlet of the utility model comprises: an air separator 20, the air separator 20 comprises a negative pressure bin 21, and an exhaust fan 22 for providing negative pressure to the negative pressure bin 21; a conveyor belt 10; and a rotatable throwing roller 30; wherein the outlet end 12 of the conveyor belt 10 is docked with the negative pressure bin 21 of the blower, and the throwing roller 30 is docked below the outlet end 12 of the conveyor belt 10, and the rotating direction of the throwing roller 30 throws the sugarcane. The sugarcane is transported from the inlet end 11 to the outlet end 12 of the conveyor belt 10 and sent into the negative pressure bin 21, and the sugarcane falls from the outlet end 12 of the conveyor belt 10 and is removed by suction under the negative pressure of the negative pressure bin 21, so that the sugarcane leaves are removed from the impurities, and when the sugarcane falls, the throwing roller 30 arranged below the outlet end 12 of the conveyor belt 10 throws the sugarcane to a high place, so that the sugarcane is dispersed in the negative pressure bin 21, which is conducive to negative pressure suction and improves the impurity removal effect.

[0027] The throwing roller 30 is located in front of and below the conveyor belt 10. Sugarcane is transported forward by the conveyor belt 10 and has a horizontal initial velocity when falling from the conveyor belt 10. Most sugarcane will fall at the front and bottom. The throwing roller 30 is set at the position where most sugarcane falls, so that more sugarcane can be thrown and dispersed, which is more conducive to the air separator 20 to suck the sugarcane leaves.

[0028] In this embodiment, the conveyor belt 10 includes a first pulley 14 located at the inlet end 11 of the conveyor belt 10, a second pulley 15 located at the outlet end 12 of the conveyor belt 10, and a chain plate 13 tensioned by the first pulley 14 and the second pulley 15. The rotation direction of the throwing roller 30 is the same as that of the first pulley 14 and the second pulley 15. The second pulley 15 and the throwing roller 30 are connected by a belt 16, and the throwing roller 30 is driven to rotate by the second pulley 15. The structural change is small, which is conducive to upgrading and transforming existing equipment.

[0029] like Figure 1 As shown, the conveyor belt 10 is tilted, and the outlet end 12 of the conveyor belt 10 is higher than the inlet end 11. This is conducive to the sugarcane falling from a high place, and the falling process is longer and easier to be scattered by the throwing roller 30, which is conducive to the air separator 20 to suck the sugarcane leaves.

[0030] like Figure 2 As shown, the outer circumference of the throwing roller 30 is provided with a plurality of ear plates 31 erected relative to the outer circumference.

[0031] The ear plate 31 is welded to the throwing roller 30, and has a firm structure, high strength, and no redundant parts, so that the redundant parts can be prevented from loosening and being thrown toward the negative pressure bin 21 and causing damage under the impact of sugarcane for a long time.

[0032] A film is installed on the ear plate 31. The film can be a rubber sheet or a film of other materials with a similar hardness to the rubber sheet. The film is softer than the ear plate 31 and can provide a certain buffer when hitting the sugarcane to avoid the sugarcane from being rotten.

[0033] One end of the film is mounted on the ear plate 31, and the other end is suspended. The film with one end suspended can provide better buffering when hitting the sugarcane. When the impact force of the sugarcane is too large, it can slide down from the suspended end of the film, reducing the impact of the sugarcane on the throwing roller 30.

[0034] like Figure 2 , 3 As shown, the ear plate 31 is provided with a mounting hole 32, and the film is detachably mounted on the mounting hole 32 by means of a bolt 34. The film is easily worn due to large forces, and is designed to be detachably mounted for easy maintenance. The mounting hole 32 includes but is not limited to a through hole, a countersunk hole, and a threaded hole.

[0035] The ear plate 31 and the rubber plate 33 are staggered with each other in the length direction of the throwing roller 30. Figure 3As shown, there are two situations: one is that the ear plates 31 are arranged in a row along the length direction, each row has more than two ear plates 31, and adjacent ear plates 31 are arranged at intervals; the second is that there are more than two rows of ear plates 31 arranged in a row, and multiple rows of ear plates 31 are arranged at intervals along the circumferential direction, and the ear plates 31 in each row are staggered. When the piles of sugar cane fall from the outlet end 12 of the conveyor belt 10, since the ear plates 31 are staggered in the length direction, the ear plates 31 and the rubber plates 33 beat the sugar cane in succession along the length direction of the throwing roller 30, so that the sugar cane is scattered and thrown to a high place, which is more conducive to the air separator 20 to extract the sugar cane leaves and improve the impurity removal effect.

[0036] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
