[0002] The application of agricultural mulch films in agricultural production has become increasingly common, and they play a significant role in promoting crop growth, improving land use efficiency and crop yield, and improving soil structure.

[0029] 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.

[0030] 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.

[0031] At present, residual film recycling machines are usually used to recycle the ground film remaining in the field. Among them, the drum spring-tooth residual film recycling machine is popular because of its efficient picking effect. The drum spring-tooth residual film recycling machine generally adopts a telescopic spring-tooth film picking mechanism to pick up the residual film. This mechanism uses spring teeth to pick up the film, and controls the movement trajectory of the spring teeth through a cam plate and an eccentric rod. When picking up the film in the soil, the spring teeth can extend from the drum, and will gradually retract into the drum after picking up the film, and will be completely retracted into the drum when reaching the film removal position. However, the spring teeth of the telescopic spring-tooth film picking mechanism are elastic, and the residual film may be ejected during the process of picking up the film in the soil, which reduces the residual film recovery rate.

[0032] In view of the above reasons, the present application embodiment provides a residual film picking mechanism, referring to Figures 1 to 8 The residual film picking mechanism includes a roller 100, a picking assembly 200, a directional disk 300 and a directional rod 400.

[0033] The roller 100 is provided with a plurality of slots 110 .

[0034] The plurality of picking assemblies 200 are evenly arranged around the central axis of the roller 100. When the roller 100 rotates, the plurality of picking assemblies 200 revolve around the central axis of the roller 100 to pick up the residual film in the field.

[0035] For example, in Figure 8 In the residual film picking mechanism, six picking assemblies 200 are evenly arranged around the central axis of the roller 100. Of course, the number of the picking assemblies 200 can also be 8, 10 or other numbers.

[0036] like Figure 2 and Figure 5As shown, the picking assembly 200 includes a film picking gear shaft 210 and a plurality of film picking teeth 220. The film picking gear shaft 210 is rotatably installed in the roller 100, parallel to the central axis of the roller 100. The plurality of film picking teeth 220 are arranged on the film picking gear shaft 210 in a direction parallel to the central axis of the roller 100. The film picking teeth 220 are used to extend into the soil to pick up the residual film in the soil. Each film picking tooth 220 corresponds to a slot hole 110 on the roller 100, and can extend out of the roller 100 through the slot hole 110 or be retracted into the roller 100 through the slot hole 110.

[0037] For example, Figure 5 16 film picking teeth 220 are arranged on the middle film picking gear shaft 210. Of course, the number of film picking teeth 220 arranged on each film picking gear shaft 210 can also be 18, 20 or other numbers.

[0038] like Figure 1 and Figure 7 As shown, the directional plate 300 is provided with an annular slide rail 310 , and the annular slide rail 310 is used to limit the sliding track of the directional rod 400 , so that one end of the directional rod 400 performs a circular motion in the annular slide rail 310 .

[0039] like Figure 1 and Figure 5 As shown, one end of the directional rod 400 is fixedly connected to one end of the film picking gear shaft 210, and the other end of the directional rod 400 is slidably connected to the annular slide rail 310. When the roller 100 rotates, one end of the directional rod 400 rotates in the annular slide rail 310, and the other end of the directional rod 400 drives the film picking gear shaft 210 to rotate in the first direction from the lowest point, and to rotate in the second direction from the highest point. The first direction and the second direction are opposite directions.

[0040] The following combination Figure 8 Describe the film picking process in detail. Figure 8In the perspective shown, the first direction is clockwise and the second direction is counterclockwise. When the film picking gear shaft 210 starts to rotate in the second direction from the highest point, the film picking teeth 220 gradually extend from the slot 110 on the roller 100, and before the film picking gear shaft 210 reaches the lowest point, the film picking teeth 220 begin to enter the soil to pick up the film. When the film picking gear shaft 210 reaches the lowest point, the front end of the film picking teeth 220 reaches point Q, and the depth of the film picking teeth 220 entering the soil reaches the maximum; as the roller 100 continues to rotate, the film picking teeth 220 move upward from point Q to pick up the residual film in the soil. When the film picking gear shaft 210 rotates in the first direction from the lowest position, the film picking gear 220 gradually retracts from the slot 110 on the roller 100. When the film picking gear shaft 210 reaches the highest position, the film picking gear 220 is completely retracted into the roller 100, and the residual film is brought to point P by the film picking gear 220 and remains on the surface of the roller 100, which is convenient for the subsequent collection of the residual film. The film picking gear 220 in the residual film picking mechanism can rotate with the film picking gear shaft 210 to gradually extend and retract from the roller 100. It is not easy to deform when touching a hard object, and the residual film will not be ejected during the film picking process, thereby improving the residual film recovery rate.

[0041] like Figure 2 As shown, the roller 100 includes a protective tube 120 and two side plates 130. The protective tube 120 is provided with a plurality of slots 110. The two side plates 130 are respectively connected to the two ends of the protective tube 120, and the two ends of the film picking gear shaft 210 are respectively rotatably connected to the two side plates 130.

[0042] The two side plates 130 support the two ends of the film picking gear shaft 210, so that the multiple film picking gear shafts 210 can rotate around their own axes while revolving around the central axis of the drum 100. When the film picking teeth 220 retract the protective tube 120, the protective tube 120 can separate the residual film from the film picking teeth 220 to prevent the residual film from winding around the film picking teeth 220, thereby ensuring the smooth progress of the film picking work.

[0043] In some embodiments of the present application, continue to refer to Figure 3 As shown, the protective cylinder 120 includes a first protective plate 121 and a second protective plate 122. The first protective plate 121 and the second protective plate 122 are alternately connected in the circumferential direction, and the first protective plate 121 and the second protective plate 122 are both provided with a plurality of slots 110 arranged in an array parallel to the central axis direction of the roller 100. The plurality of slots 110 on the first protective plate 121 and the plurality of slots 110 on the second protective plate 122 are arranged alternately, and the plurality of slots 110 on the first protective plate 121 and the plurality of slots 110 on the second protective plate 122 correspond to a plurality of film picking teeth 220 installed on a film picking tooth shaft 210, respectively.

[0044] A film picking gear shaft 210 is correspondingly disposed on the inner side of each first guard plate 121, and a film picking gear shaft 210 is correspondingly disposed on the inner side of each second guard plate 122. The multiple slots 110 on the first guard plate 121 are staggered with the multiple slots 110 on the second guard plate 122, and correspondingly, the multiple film picking teeth 220 on the film picking gear shaft 210 on the inner side of the first guard plate 121 are staggered with the multiple film picking teeth 220 on the film picking gear shaft 210 on the inner side of the second guard plate 122.

[0045] Figure 4 , a specific structure for realizing the connection between the first guard plate 121 and the second guard plate 122 is shown in FIG. Specifically, the roller 100 further includes a square tube 160 and a square plate 170. Both ends of the square tube 160 are respectively connected to the two side plates 130; the square plate 170 is connected to the square tube 160 and extends in a direction parallel to the central axis of the roller 100. The first guard plate 121 and the second guard plate 122 are both connected to the square plate 170. Bolts pass through the first guard plate 121, the square plate 170, and the second guard plate 122, and nuts are tightened on the bolts.

[0046] In some other embodiments of the present application, the protective tube 120 is an integrated structure. Specifically, the protective tube 120 is formed by winding and welding a plate provided with a plurality of slots 110 .

[0047] like Figure 2 and Figure 3 As shown, the roller 100 further includes a support plate 140 and a plurality of support sleeves 150. The support plate 140 is located in the casing 120 and connected to the inner wall of the casing 120. The plurality of support sleeves 150 are respectively sleeved on the plurality of film picking gear shafts 210 in a one-to-one correspondence and connected to the support plate 140.

[0048] When the film picking teeth 220 are inserted into the field to pick up the residual film, the film picking gear shaft 210 is easily subjected to force and bent. The support plate 140 and the plurality of support sleeves 150 provide intermediate support for the film picking gear shaft 210 to prevent the film picking gear shaft 210 from bending or reduce the bending degree of the film picking gear shaft 210.

[0049] The embodiment of the present application provides a specific structure of the directional disk 300, such as Figure 7 As shown, the directional plate 300 includes an inner circular plate 320, an outer circular plate 330 and an outer plate 340. The inner circular plate 320 and the outer circular plate 330 are concentrically arranged on the end surface of the outer plate 340 facing the roller 100 to form an annular slide rail 310. The end of the directional rod 400 away from the film picking gear shaft 210 is located between the inner circular plate 320 and the outer circular plate 330.

[0050] Specifically, the inner circular plate 320 and the outer circular plate 330 may be welded to the end surface of the outer plate 340 facing the roller 100 , and the inner circular plate 320 , the outer circular plate 330 and the outer plate 340 may also be an integral structure.

[0051] The outer wall of the inner circular plate 320, the inner wall of the outer circular plate 330 and the end face of the outer plate 340 facing the roller 100 together define an annular slide rail 310, and the end of the directional rod 400 away from the film picking gear shaft 210 is surrounded by the annular slide rail 310, so that the end of the directional rod 400 away from the film picking gear shaft 210 can make a circular motion in the annular slide rail 310.

[0052] In order to facilitate the installation of the end of the directional rod 400 away from the film picking gear shaft 210 in the annular slide rail 310, the outer circular plate 330 in the embodiment of the present application is provided with a notch, and the directional plate 300 also includes an arc plate 350, which is detachably connected to the outer plate 340 and is located at the notch. The inner wall of the arc plate 350 and the inner wall of the outer circular plate 330 are located on the same cylindrical surface. For example, Figure 7 As shown, the arc plate 350 is detachably connected to the outer plate 340 by bolts and nuts.

[0053] When the end of the directional rod 400 away from the film picking gear shaft 210 is installed in the annular slide rail 310, the arc plate 350 is removed from the outer plate 340, and the end of the directional rod 400 enters the annular slide rail 310 through the groove on the outer circular plate 330, and then the arc plate 350 is connected to the outer plate 340.

[0054] like Figure 6 As shown, the directional rod 400 includes a connecting rod 410, a fixed shaft 420 and a roller 430. One end of the connecting rod 410 is connected to the end of the film picking gear shaft 210, and the other end of the connecting rod 410 is connected to one end of the fixed shaft 420. The roller 430 is rotatably connected to the end of the fixed shaft 420 away from the connecting rod 410 and is installed on the annular slide rail 310.

[0055] When the residual film picking mechanism is working, Figure 8 As shown, the roller 430 performs circular motion in the annular slide rail 310 and drives the film picking gear shaft 210 to rotate around its own axis through the fixed shaft 420 and the connecting rod 410.

[0056] Continue to refer to Figure 6 The connecting rod 410 is provided with a mounting hole 411 and a gap 412 connected to the mounting hole 411. The directional rod 400 further includes a fastener 440, which is mounted on the end of the connecting rod 410 and passes through the gap 412, and is configured to reduce the gap 412. The mounting hole 411 is sleeved on the end of the film picking gear shaft 210.

[0057] When the connecting rod 410 is connected to the film picking gear shaft 210 , the end of the film picking gear shaft 210 is placed in the mounting hole 411 , and the fastener 440 is tightened to reduce the gap 412 , so that the inner wall of the mounting hole 411 clamps the end of the film picking gear shaft 210 .

[0058] like Figure 1 As shown, the residual film picking mechanism further includes a transmission assembly 500. The transmission assembly 500 is connected to the roller 100 and is configured to drive the roller 100 to rotate. The tractor pulling the residual film recycling machine transmits power to the transmission assembly 500, and the transmission assembly 500 drives the roller 100 to rotate to pick up the residual film.

[0059] The embodiment of the present application provides a specific structure of the transmission assembly 500. The transmission assembly 500 includes a transmission wheel 510 and a rotating shaft 520. The rotating shaft 520 extends along the central axis of the roller 100 and is connected to the roller 100. The transmission wheel 510 is installed at the end of the rotating shaft 520 away from the directional disk 300. The transmission wheel 510 can be a sprocket, a gear or a pulley.

[0060] Continue to refer to Figure 1 As shown, the residual film picking mechanism further includes an anti-entanglement ring 600. The anti-entanglement ring 600 is installed on the end surface of the roller 100 facing the transmission wheel 510 and surrounds the rotating shaft 520.

[0061] The anti-entanglement ring 600 surrounds the rotating shaft 520, which can prevent the residual film from winding around the rotating shaft 520 and causing the roller 100 to stop working, thereby ensuring that the residual film picking mechanism can operate continuously and efficiently.

[0062] 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.

[0063] 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.
