[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0036] A cutting unit impurity removal device, such as Figure 1As shown, including the elevator 1, fan 2 and header 3. Among them, the header 3 is provided with a conveying chute 4, and the header 3 can harvest crops during work, and the harvested crops can reach the conveying chute 4, and finally be conveyed to the fan 2 by the conveying chute 4. The fan 2 is located on one side of the conveying chute 4, and the inlet of the fan 2 communicates with the outlet of the conveying chute 4, and the inlet of the elevator 1 communicates with the outlet of the conveying chute 4, and is located opposite the fan 2, and the horizontal height of the inlet of the fan 2 is greater than the horizontal height of the inlet of the elevator 1, so that the crops (such as corn) cannot enter the fan 2. In addition, the fan 2 is detachably connected with the elevator 1 and the conveying chute 4 by bolts, and the conveying chute 4 is detachably connected with the header 3 by bolts.

[0037] It should be noted that the power of the fan 2 can be set as needed, and the fan 2 needs to ensure that the crops do not enter the fan 2 during work, and the waste of the crops can be adsorbed by the fan 2.

[0038] For example, taking corn as an example, after the header 3 harvests corn, it will carry part of the corn ear, stalk and corn leaf into the conveying chute 4, and then the corn ear, stalk and corn leaf can be adsorbed by the fan 2 at the outlet position of the conveying chute 4, and the harvested corn enters the elevator 1, which can avoid the accumulation and blockage of a large amount of corn ear, stalk and corn leaf at the bottom of the conveying chute 4 (the inlet of the elevator 1), thereby improving the harvesting efficiency.

[0039] Further, the conveying chute 4 is provided with an auger, which can convey the corn, corn ear, stalk and corn leaf from the top of the header 3 to the position of the elevator 1. One surface of the conveying chute 4 is provided with a mesh for observing the working state of the auger through the mesh.

[0040] As shown in Figure 2 The conveying chute 4 is arranged in a vertical direction, and at least two opposite outlets are formed in the bottom side wall; at least one outlet of the conveying chute 4 is used to communicate with the inlet of the fan 2; and at least one outlet of the conveying chute 4 is used to communicate with the inlet of the elevator 1.

[0041] It should be noted that in order to ensure that the corn and straw can be effectively separated, the bottom of the conveying chute 4 needs to be provided with multiple outlets, one of which is used to communicate with the fan 2 to adsorb straw and corn leaves, and the other is used to convey corn into the elevator 1.

[0042] As shown in Figure 3As shown, the fan 2 comprises a housing 201, a fan blade 204, a cutting knife 205 and a driving shaft 206. The housing 201 is provided with an inlet 202 and an outlet 203, the inlet 202 is communicated with the outlet of the conveying groove 4, and the outlet 203 is towards the ground. The driving shaft 206 is arranged at the center of the housing 201 and is rotationally connected with the housing 201; the fan blade 204 is provided with a plurality of fan blades and is installed on the driving shaft 206; the cutting knife 205 is installed on the driving shaft 206 and is located between the fan blade 204 and the inlet 202 along the airflow path of the fan 2. In addition, the housing 201 is a double-layer structure, the inlet 202 is located on the side wall of the first layer structure of the housing 201, and the outlet 203 is located on the side wall of the second layer structure of the housing 201, and the first layer structure is located above the second layer structure.

[0043] It should be noted that when the fan 2 works, firstly, the fan blade 204 rotates to generate suction force to suck the straws and corn leaves into the fan 2. Then the straws and corn leaves reach the position of the cutting knife 205 and are cut, and finally the cut straws and corn leaves are discharged through the outlet 203. In general, after the action of the fan 2, the straws and corn leaves and other sundries in the conveying groove 4 can be sucked into the fan 2, effectively avoiding the blockage of the conveying groove 4 and the elevator 1, thereby improving the working efficiency.

[0044] Further, the side wall of the first layer structure of the housing 201 is further hinged with an arc-shaped sealing door 2011, and the sealing door 2011 is located opposite to the inlet 202.

[0045] It should be noted that in the working state, the sundries such as straws and corn leaves may also be accumulated inside the housing 201, so the housing 201 can be opened through the sealing door 2011 after a period of time, and then the sundries accumulated inside the housing 201 are manually cleaned.

[0046] Further, in combination with Figure 4 It can be known that the end of the driving shaft 206 is provided with a chain wheel, and the chain wheel can be transmissionally connected with an engine through a chain, and the engine is generally installed at the middle of a vehicle body (the vehicle body is provided with the above-mentioned header and impurity removing device). Of course, in addition to the chain wheel transmission, gear and belt wheel transmission modes can also be used, and the specific mode is subject to the actual situation.

[0047] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: still can modify the technical scheme recorded in foregoing each embodiment, or equivalent replacement is carried out to part technical features to foregoing each embodiment; and these modifications or replacements do not make the essence of corresponding technical scheme deviate from the spirit and scope of the technical scheme of each embodiment of the utility model.
