DETAILED DESCRIPTION

[0021] The film picking device in the residual film recycling machine continuously picks up the residual film in the soil through the rotating film picking blade. However, in the process of picking up the residual film, impurities such as soil and straw will be picked up along with the residual film. After being picked up by the film picking device, these impurities will fall to the film picking position in front, causing the impurities to accumulate at the film picking position, and then the collected residual film will have more impurities.

[0022] In view of the above reasons, an embodiment of the present application provides a residual film impurity removal device to avoid the accumulation of impurities at the film picking position and reduce the impurities in the residual film collected by the residual film recovery machine.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0025] The embodiment of the present application provides a residual film impurity removal device, such as Figures 1 to 4 As shown, it includes a driving mechanism 1, an auger shaft 2, an auger blade 3 and a casing 4.

[0026] The housing 4 is connected to the frame and opens toward the film picking device 6, and is located in front of the film picking device 6. Specifically, the housing 4 can be connected to the frame 5 by welding, bolting, etc. The housing 4 can receive debris such as soil and straw dropped from the film picking device 6.

[0027] The auger shaft 2 is located in front of the film picking device 6, and both ends of the auger shaft 2 are rotatably connected to the housing 4, and one end of the auger shaft 2 is transmission-connected to the driving mechanism 1. Specifically, two bearing seats are provided on the housing 4, and bearings are installed at both ends of the auger shaft 2. The bearings at both ends of the auger shaft 2 are installed in the bearing seats on the housing 4, so that the auger shaft 2 can rotate around its own central axis.

[0028] The auger blade 3 is arranged on the outer circumferential surface of the auger shaft 2 and extends along the length direction of the auger shaft 2. When the auger blade 3 rotates, it can push the impurities to move along the length direction of the auger shaft 2. Specifically, the auger blade 3 is connected to the outer circumferential surface of the auger shaft 2 by welding, bonding, etc.

[0029] When the residual film removal device provided in the embodiment of the present application is working, the driving mechanism 1 drives the auger shaft 2 to rotate, and then the auger blades 3 rotate in the outer shell 4; impurities such as soil and straw that fall from the film picking device 6 enter the interior of the outer shell 4 through the opening of the outer shell 4, and the continuously rotating auger blades 3 discharge the impurities that fall into the outer shell 4 from the end of the outer shell 4, thereby avoiding the accumulation of impurities at the film picking position, thereby reducing the impurities in the residual film collected by the residual film recovery machine.

[0030] The embodiment of the present application provides a specific structure of the housing 4, such as Figure 2As shown. The outer shell 4 includes a first baffle 41, a second baffle 42, a third baffle 43, a baffle cover 44 and an outer plate 45. The outer plate 45 surrounds the outer side of the auger blade 3 and is open toward the film picking device 6. The first baffle 41 and the second baffle 42 are arranged at both ends of the outer plate 45 and are connected to the frame 5, and a conveying through hole 421 is opened on the second baffle 42. The baffle cover 44 is connected to the side of the second baffle 42 facing away from the outer plate 45, and the third baffle 43 is connected to the end of the baffle cover 44 away from the second baffle 42. The two ends of the auger shaft 2 are rotatably connected to the first baffle 41 and the third baffle 43, respectively, and pass through the conveying through hole 421.

[0031] The first baffle 41 and the third baffle 43 provide installation positions for the auger shaft 2. Specifically, the first baffle 41 and the third baffle 43 are both provided with bearing seats, and bearings are respectively installed at both ends of the auger shaft 2, and the bearings are installed in the bearing seats so that the auger shaft 2 can rotate around its own axis.

[0032] When the residual film removal device provided in the embodiment of the present application is working, the auger blades 3 rotate driven by the auger shaft 2, and the auger blades 3 push the soil, straw and other impurities in the outer shell 4, so that the impurities move along the length direction of the auger shaft 2 and pass through the conveying through hole 421, and finally are discharged from between the second baffle 42 and the third baffle 43.

[0033] Reference Figure 2 and Figure 4 The peripheral plate 45 in the embodiment of the present application includes a first straight plate 451, an arc plate 452, and a second straight plate 453 connected in sequence. Exemplarily, the first straight plate 451 and the arc plate 452, and the second straight plate 453 and the arc plate 452 are integrally connected. The first straight plate 451 and the arc plate 452, and the second straight plate 453 and the arc plate 452 can also be connected by welding, bonding, etc.

[0034] The first straight plate 451 is located on the side of the auger blade 3 away from the film picking device 6. The arc plate 452 surrounds the outer side of the auger blade 3. The side of the second straight plate 453 away from the arc plate 452 extends toward the film picking device 6.

[0035] When the residual film removal device is working, impurities such as soil and straw that fall from the film picking device 6 fall onto the second straight plate 453. When the auger blade 3 rotates, the arc plate 452 and the first straight plate 451 block the impurities, causing the impurities to move along the length direction of the auger shaft 2 and finally be discharged from the end of the outer shell 4.

[0036] Further, continue to refer to Figure 2 As shown, the housing 4 in the embodiment of the present application further includes a circular tube 46 , which is disposed on a side of the second straight plate 453 away from the arc plate 452 and extends along the length direction of the arc plate 452 .

[0037] When the residual film removal device provided in the embodiment of the present application is working, the side of the second straight plate 453 away from the arc plate 452 is in contact with impurities such as soil and straw for a long time. If the side of the second straight plate 453 away from the arc plate 452 is not provided with a circular tube 46, the side of the second straight plate 453 away from the arc plate 452 is prone to deformation.

[0038] A round tube 46 is provided on the side of the second straight plate 453 away from the arc plate 452 . The round tube 46 is in direct contact with impurities, thereby preventing the side of the second straight plate 453 away from the arc plate 452 from being deformed.

[0039] Specifically, the central axis of the arc plate 452 coincides with the central axis of the auger shaft 2, so that the distance from the edge of the auger blade 3 to each part of the arc plate 452 is equal. When the auger blade 3 pushes impurities, each part of the arc plate 452 is subjected to force more evenly, avoiding the situation where the auger blade 3 is locally subjected to excessive force and deformed.

[0040] The embodiment of the present application provides a specific structure of the auger shaft 2, referring to Figure 3 The auger shaft 2 includes a shaft barrel 21, a shaft head 22 and a support plate 23. One end of each of the two shaft heads 22 extends into the shaft barrel 21 and is connected to the inner wall of the shaft barrel 21 through the support plate 23, and the other end of each of the two shaft heads 22 is located outside the shaft barrel 21 and is rotatably connected to the housing 4. The auger blade 3 is arranged on the outer circumferential surface of the shaft barrel 21.

[0041] The auger shaft 2 adopts the above structure, which reduces the mass of the auger shaft 2 while ensuring the required diameter size, thereby realizing a lightweight design of the auger shaft 2.

[0042] The embodiment of the present application provides a specific structure of the driving mechanism 1, referring to Figure 4 As shown. The driving mechanism 1 includes a reducer 11, a transmission shaft 12, a first transmission wheel 13 and a second transmission wheel 14. The input end of the reducer 11 is used to connect to the rear end output shaft of the tractor. One end of the transmission shaft 12 is connected to the output end of the reducer 11, and the other end of the transmission shaft 12 is installed with the first transmission wheel 13. The second transmission wheel 14 is installed at one end of the auger shaft 2 and is transmission-connected to the first transmission wheel 13.

[0043] When the residual film recycling machine is working, it needs to be connected to the tractor and powered by the tractor. The input end of the reducer 11 is indirectly connected to the rear output shaft of the tractor; the power of the tractor is decelerated by the reducer 11 and then transmitted to the transmission shaft 12. The first transmission wheel 13 on the transmission shaft 12 rotates and drives the second transmission wheel 14 to rotate. The auger shaft 2 rotates under the drive of the second transmission wheel 14.

[0044] For example, Figure 4As shown, the first transmission wheel 13 and the second transmission wheel 14 are both pulleys, and the driving mechanism 1 further includes a belt 15. The belt 15 is wound around the first transmission wheel 13 and the second transmission wheel 14. The power of the first transmission wheel 13 is transmitted to the second transmission wheel 14 via the belt 15.

[0045] The residual film removal device works in the field, the working environment is relatively bad, and there are many vibrations and impacts during the working process. The first transmission wheel 13 and the second transmission wheel 14 are connected by a belt 15 for transmission, which can reduce the impact and vibration during the transmission process and make the transmission more stable. In addition, the maintenance cost of the belt 15 is relatively low, and only regular inspection and replacement are required.

[0046] Of course, the first transmission wheel 13 and the second transmission wheel 14 are not limited to pulleys. In other embodiments of the present application, the first transmission wheel 13 and the second transmission wheel 14 can also be other structures. For example, the first transmission wheel 13 and the second transmission wheel 14 are gears, and the first transmission wheel 13 and the second transmission wheel 14 are meshed.

[0047] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0048] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
