Description

Technical Field

[0001] The present application relates to the technical field of agricultural machinery, and in particular to a residual film packaging mechanism. Background Art

[0002] Mulching refers to a measure of covering the ground surface with agricultural plastic film, which can reduce the impact of raindrops, prevent erosion and crust formation, effectively reduce the evaporation of soil moisture, promote the absorption and growth of crops, and improve the utilization efficiency of soil moisture. However, with the increasing use of mulching film, the amount of mulching film remaining in the fields is also increasing, which has led to problems such as soil compaction, environmental pollution and reduced crop yields.

[0003] In order to remove the mulch film remaining in the fields and reduce environmental pollution, agricultural practitioners use residual film recycling machines to pick up and collect the residual mulch film in the fields. During operation, the existing residual film recycling machines pick up the mulch film and directly transfer it to the collection frame. However, this collection method causes the mulch film to be scattered and disordered in the collection frame. When the mulch film in the collection frame accumulates to full load, the driver of the residual film recycling machine will pour it out. However, in the case of strong winds, both the mulch film in the collection frame and the mulch film that has been poured out of the collection frame on the ground may be blown away by the strong wind, which will cause environmental pollution problems again.

DETAILED DESCRIPTION

[0022] 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.

[0023] 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", "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.

[0024] The present application embodiment provides a residual film packaging mechanism, such as Figures 1 to 3 As shown. The residual film packaging mechanism includes two winding assemblies 1 and two baffles 2. The two winding assemblies 1 are arranged at an acute angle, and the two baffles 2 are arranged on both sides of the two winding assemblies 1 to enclose a winding space. The two winding assemblies 1 are respectively configured to apply friction forces in opposite directions to the residual film entering the winding space, so that the residual film is wound into a cylindrical shape.

[0025] For example, in Figure 1 and Figure 2 In the residual film packaging mechanism shown, the winding assembly 1 located at the top can apply an outward friction force to the residual film in the winding space, and the winding assembly 1 located at the bottom can apply an inward friction force to the residual film in the winding space.

[0026] When the residual film packaging mechanism provided in the embodiment of the present application is working, the two winding assemblies 1 apply frictional force in the opposite direction to the residual film transported to the winding space by the residual film recovery machine, so that the residual film is wound into a cylindrical shape. When the diameter of the residual film wound into a cylindrical shape reaches a preset value, the two winding assemblies 1 of the residual film packaging mechanism are controlled to stop working, and the packaged residual film is taken out of the winding space.

[0027] The preset value may be 1 m, 0.8 m, etc. The operator of the residual film recycling machine may roughly judge by observation whether the diameter of the cylinder wound by the residual film reaches the preset value.

[0028] The two winding assemblies 1 and two baffles 2 of the residual film packaging mechanism provided in the embodiment of the present application form a barrier to the residual film, so that the residual film in the winding space is not easily blown out of the residual film packaging mechanism by the wind. In addition, the residual film packaging mechanism winds the residual film into a cylindrical shape, and the residual film taken out of the residual film packaging mechanism is not easily blown away by the wind. Therefore, the residual film packaging mechanism provided in the embodiment of the present application can package the residual film to prevent it from being blown away when the wind is strong, thereby avoiding the residual film from polluting the environment again, and at the same time, the packaged residual film can be better stored and processed.

[0029] Continue to refer to Figures 1 to 3 , the embodiment of the present application provides a specific structure of a winding assembly 1. The winding assembly 1 includes an active roller shaft 11, a driven roller shaft 12, a belt 13 and two side plates 14. The two side plates 14 are arranged at intervals. The active roller shaft 11 is arranged in parallel with the driven roller shaft 12, and the two ends of the active roller shaft 11 and the two ends of the driven roller shaft 12 are rotatably connected to the two side plates 14 respectively. The belt 13 is wound around the active roller shaft 11 and the driven roller shaft 12, and is configured to apply friction to the residual film in the winding space.

[0030] The two side plates 14 provide installation positions for the active roller 11 and the driven roller 12, and the two side plates 14 are connected to the frame to connect the residual film packaging mechanism to the residual film recycling machine. The two active rollers 11 are connected to the power transmission structure of the residual film recycling machine, and the active rollers 11 rotate to drive the belt 13 to rotate, and the driven roller 12 rotates with the belt 13. The outer surface of the belt 13 can apply friction to the residual film in the winding space, and the two belts 13 are arranged at an acute angle to compress the residual film in the winding space.

[0031] Since the belt 13 needs to compress the residual film in the winding space, it will be easily deformed by the reaction force exerted by the residual film. In order to prevent the belt 13 from being greatly deformed and affecting the normal rotation of the belt 13, the winding assembly 1 also includes a support assembly 15, such as Figure 3 Specifically, the support assembly 15 is located inside the belt 13 and connected to the two side plates 14, pressing against the inner side of the belt 13. The support assembly 15 supports the belt 13 to prevent the belt 13 from being greatly deformed due to the reaction force of the residual film.

[0032] Furthermore, the support assembly 15 in the embodiment of the present application includes two connection seats 151 and a plurality of support rollers 152. The two connection seats 151 are respectively arranged on the inner sides of the two side plates 14. The plurality of support rollers 152 are arranged in parallel, and the two ends of each support roller 152 are respectively rotatably connected to the two connection seats 151, and the outer circumferential surface of each support roller 152 is pressed against the inner surface of the belt 13.

[0033] For example, Figure 3Each support assembly 15 shown in the figure includes four support rollers 152. Of course, the support rollers 152 in each support assembly 15 can also be five, six or other numbers.

[0034] Specifically, the connection seat 151 and the inner side of the side plate 14 can be connected by welding, bolt connection, riveting, etc. A circular hole is provided on the connection seat 151, and the end of the support roller 152 is arranged in the circular hole of the connection seat 151 and can rotate in the circular hole.

[0035] When the belt 13 rotates driven by the active roller 11 , the support roller 152 presses against the inner surface of the belt 13 and rotates along with the belt 13 . The support roller 152 supports the belt 13 to prevent the belt 13 from being greatly deformed.

[0036] like Figures 1 to 3 As shown, the embodiment of the present application provides a specific structure of the side plate 14. The side plate 14 includes a first connecting section 141, a second connecting section 142 and a fastener. The two ends of the active roller shaft 11 are respectively connected to the two first connecting sections 141, and the two ends of the driven roller shaft 12 are respectively connected to the two second connecting sections 142. The first connecting section 141 is provided with a mounting through hole. The second connecting section 142 is provided with a long hole corresponding to the mounting through hole, and the long hole extends along the length direction of the second connecting section 142. The fastener passes through the mounting through hole and the long hole to fix the first connecting section 141 and the second connecting section 142.

[0037] The side plate 14 can be adjusted in length through the above structure, thereby adjusting the tightness of the belt 13. Specifically, by changing the position of the long hole where the installation through hole is located and fixing the first connecting section 141 and the second connecting section 142 with a fastener, the overlapping length of the first connecting section 141 and the second connecting section 142 is changed, the overall length of the side plate 14 is adjusted, and the tightness of the belt 13 is adjusted.

[0038] Reference Figure 4 The winding assembly 1 in the embodiment of the present application further includes a transmission assembly 16, and the two ends of the transmission assembly 16 are respectively connected to the two active rollers 11. The transmission assembly 16 connects the two active rollers 11, so that when one of the active rollers 11 rotates, the other active roller 11 also rotates. Furthermore, only one of the active rollers 11 needs to be connected to the transmission structure of the residual film recycling machine.

[0039] The specific structure of the transmission assembly 16 of the embodiment of the present application. The transmission assembly 16 includes a first sprocket 161, a chain 163 and a second sprocket 162. The first sprocket 161 and the second sprocket 162 are respectively connected to one end of the active roller shaft 11 of the two winding assemblies 1. The chain 163 is wound around the first sprocket 161 and the second sprocket 162.

[0040] Specifically, a first sprocket 161 is installed at one end of the active roller shaft 11 of the winding assembly 1 located at the bottom, and a second sprocket 162 is installed at one end of the active roller shaft 11 of the winding assembly 1 located at the top.

[0041] For example, a third sprocket is installed at the other end of the active roller shaft 11 of the winding assembly 1 located at the bottom, and the third sprocket is connected to the transmission structure of the residual film recovery machine. The transmission structure of the residual film recovery mechanism transmits power to the third sprocket, thereby causing the two active roller shafts 11 to rotate synchronously. Of course, the third sprocket can also be installed at the other end of the active roller shaft 11 of the winding assembly 1 above.

[0042] like Figure 4 As shown, the residual film packaging mechanism provided in the embodiment of the present application also includes an opening and closing component 3, which is connected to the two winding components 1 and the frame and is configured to drive the winding component 1 located above away from the residual film in the winding space.

[0043] When the driver of the residual film recycling machine determines that the diameter of the cylinder formed by the residual film in the winding space reaches a preset value, the opening and closing component 3 is controlled to lift the winding component 1 located above, so that the winding component 1 located above no longer clamps the residual film, thereby facilitating the discharge of the residual film from the winding space.

[0044] In addition, the direction of the friction force applied to the residual film by the two winding assemblies 1 in the embodiment of the present application can be as follows: Figure 1 When the winding assembly 1 located at the top is lifted up and separated from the residual film, the residual film is only subjected to the friction force applied by the winding assembly 1 located at the bottom, and then the residual film wound into a cylindrical shape is discharged outward by the winding assembly 1 located at the bottom.

[0045] Specifically, the embodiment of the present application provides a specific structure of the opening and closing assembly 3. The opening and closing assembly 3 includes a telescopic member 31 and a support member 32. One end of the support member 32 is fixedly connected to the frame, and the other end of the support member 32 is rotatably connected to the winding assembly 1 located above. The two ends of the telescopic member 31 are respectively hinged to the two winding assemblies 1, and the winding assembly 1 located below is fixedly connected to the frame.

[0046] When the winding assembly 1 at the top needs to be lifted, the telescopic member 31 extends, and the winding assembly 1 at the top rotates around the end of the support member 32, thereby allowing the winding assembly 1 at the top to be separated from the residual film in the winding space. When the winding assembly 1 at the top needs to be lowered, the telescopic member 31 shortens, and the winding assembly 1 at the top rotates around the end of the support member 32, thereby allowing the winding assembly 1 at the top to press the residual film in the winding space.

[0047] Exemplarily, the telescopic member 31 may be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, or the like.

[0048] like Figure 4As shown, the residual film packaging mechanism provided in the embodiment of the present application further includes a cover plate 4, which is connected to the two baffles 2 and is located above the winding space. The cover plate 4 further blocks the residual film in the winding space to prevent the residual film from scattering from the winding space.

[0049] 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.

[0050] 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.
