DETAILED DESCRIPTION

[0019] 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.

[0020] 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.

[0021] The embodiment of the present application provides a speed matching mechanism for a residual film recycling machine, such as Figures 1 to 3 As shown, it includes a bracket 3, a contoured wheel 4 and a transmission assembly 5.

[0022] Two brackets 3 are connected to the bottom of the frame 1 at intervals, providing a basis for the installation of the profiling wheel 4. The two ends of the profiling wheel 4 are rotatably installed on the two brackets 3, and the profiling wheel 4 is arranged parallel to the film picking roller 2. Specifically, a bearing seat is arranged on each bracket 3, and bearings are arranged at both ends of the profiling wheel 4, and two bearings are correspondingly installed in the two bearing seats. The two ends of the transmission assembly 5 are respectively connected to one end of the profiling wheel 4 and one end of the film picking roller 2, so as to make the film picking roller 2 rotate with the profiling wheel 4.

[0023] When the speed matching mechanism of the residual film recycling machine provided in the embodiment of the present application is working, the contour wheel 4 contacts the soil and rotates, and the contour wheel 4 drives the film picking roller 2 to rotate through the transmission assembly 5, so that the rotation speed of the film picking roller 2 is matched with the travel speed of the residual film recycling machine, thereby avoiding the leakage of residual film and improving the effect of picking up residual film.

[0024] like Figure 1 and Figure 2 As shown, the speed matching mechanism of the residual film recycling machine provided in the embodiment of the present application further includes a scraper 6. The scraper 6 is located behind the traveling direction of the profiling wheel 4, connected to the bottom of the frame 1 and extending downward, and the scraper 6 is inclined toward the traveling direction of the profiling wheel 4 and close to the surface of the profiling wheel 4.

[0025] When the residual film recycling machine is working in the field, the profiling wheel 4 contacts the soil, and the soil adheres to the surface of the profiling wheel 4. The scraper 6 can clean the soil off the profiling wheel 4, avoiding the situation where the profiling wheel 4 is difficult to move due to the accumulation of soil on the profiling wheel 4.

[0026] Reference Figure 3 The contour wheel 4 in the embodiment of the present application is located behind the film picking roller 2 in the traveling direction.

[0027] When the film picking roller 2 is working, the film picking teeth of the film picking roller 2 will be inserted into the soil to pick out the residual film in the soil. The soil after the film picking roller 2 picks up the residual film will be turned over, and the profiling wheel 4 is arranged behind the traveling direction of the film picking roller 2 to level the soil, which is convenient for subsequent planting.

[0028] Figure 2 The specific structure of the transmission assembly 5 in the embodiment of the present application is shown in FIG. Figure 2 As shown, the transmission assembly 5 includes a first sprocket 51, a second sprocket 52 and a chain 53. The first sprocket 51 is connected to one end of the contour wheel 4. The second sprocket 52 is used to be connected to one end of the film picking roller 2. The chain 53 is wound around the first sprocket 51 and the second sprocket 52.

[0029] When the profiling wheel 4 contacts with the soil and rotates, the first sprocket 51 installed at one end of the profiling wheel 4 rotates with the profiling wheel 4, and the chain 53 transmits the power of the first sprocket 51 to the second sprocket 52. The second sprocket 52 drives the film picking roller 2 to rotate, so that the rotation speed of the film picking roller 2 is synchronized with the rotation speed of the profiling wheel 4, that is, the rotation speed of the film picking roller 2 is synchronized with the travel speed of the residual film recovery machine.

[0030] The chain transmission method adopted between the contour wheel 4 and the film picking roller 2 in the embodiment of the present application can prevent slipping and ensure the precise speed matching between the film picking roller 2 and the residual film recovery machine; moreover, the chain transmission can be used in harsh environments such as humidity and dust, and can better adapt to the working environment of the field.

[0031] It should be noted that the specific structure of the transmission assembly 5 is not limited to the above content. In other embodiments of the present application, the transmission assembly 5 can also be in other structural forms. For example, the transmission assembly 5 includes a first pulley, a second pulley and a belt; the first pulley is connected to one end of the contour wheel 4, the second pulley is used to connect to one end of the film picking roller 2, and the belt is wound around the first pulley and the second pulley.

[0032] Continue to refer to Figure 1 The contoured wheel 4 in the embodiment of the present application includes a rotating shaft 41, a roller 42 and a plurality of spoke plates 43. The rotating shaft 41 is coaxially arranged in the roller 42, and both ends of the rotating shaft 41 extend out of the roller 42 and are rotatably connected to the bracket 3, and one end of the rotating shaft 41 is connected to the transmission assembly 5. The plurality of spoke plates 43 are arranged in a circular array around the rotating shaft 41, and each spoke plate 43 is connected to the inner wall of the rotating shaft 41 and the roller 42. Specifically, each spoke plate 43 can be connected to the inner wall of the rotating shaft 41 and the roller 42 by welding.

[0033] When the residual film recycling machine is picking up residual film, the outer surface of the roller 42 contacts the soil and rotates with the movement of the residual film recycling machine, and the roller 42 drives the rotating shaft 41 to rotate through a plurality of spoke plates 43. The above-mentioned contour wheel 4 structure can ensure that the contour wheel 4 has good rigidity and small mass.

[0034] Furthermore, if Figure 3 As shown, the speed matching mechanism of the residual film recycling machine provided in the embodiment of the present application further includes a folding assembly 7 and a running wheel 8. The two ends of the folding assembly 7 are respectively connected to the bottom of the frame 1 and the running wheel 8, and are configured to drive the running wheel 8 to fold toward the frame 1 and unfold from the frame 1.

[0035] When the residual film recycling machine needs to travel on the road, the folding assembly 7 is unfolded to make the traveling wheel 8 contact the road surface, and the contour wheel 4 is in a suspended state at this time to prevent the contour wheel 4 from contacting the road surface and being damaged.

[0036] The present application embodiment provides a specific structure of the folding assembly 7, referring to Figure 3 The folding assembly 7 comprises a rocker arm 71 and a hydraulic rod 72. The two ends of the rocker arm 71 are rotatably connected to the bottom of the frame 1 and the travel wheel 8. The two ends of the hydraulic rod 72 are rotatably connected to the middle of the rocker arm 71 and the bottom of the frame 1.

[0037] Specifically, one end of the rocker arm 71 is rotatably connected to the bottom of the frame 1 using a pin, and the other end of the rocker arm 71 is welded to the rotating shaft of the travel wheel 8. Both ends of the hydraulic rod 72 are rotatably connected to the middle of the rocker arm 71 and the bottom of the frame 1 using a pin.

[0038] When the residual film recycling machine needs to travel on the road, the rocker arm 71 is pulled to extend the hydraulic rod 72, so that the rocker arm 71 is unfolded and fixed from the frame 1, and the travel wheel 8 is supported on the road surface, so that the contour wheel 4 is in a suspended state. When the residual film recycling machine needs to work in the field, the rocker arm 71 is pulled to shorten the hydraulic rod 72, so that the rocker arm 71 is folded and fixed toward the frame 1, and the contour wheel 4 is in contact with the soil.

[0039] 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.

[0040] 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.
