Description

Technical Field

[0002] After the crops are harvested, the farmland needs to be plowed and reorganized to prepare for planting next year. However, after the crops are harvested, there will be straw and mulch in the farmland, which need to be processed separately before farming can be carried out.

[0003] The main components of ground film materials are polymer compounds. Under natural conditions, these polymers are difficult to decompose. The loss of production caused by a large amount of waste film pollution will exceed the yield increase benefits that can be brought by film planting. In the long run, the soil will be severely polluted, seriously affecting the growth and development of crops and eventually leading to the abandonment of cultivated land. In addition, if the waste film is directly discarded, it will also lead to a certain waste of resources. Therefore, after the crops are harvested, the waste film needs to be recycled and reused.

[0037] After the crops are harvested, the farmland needs to be plowed and reorganized to prepare for planting next year. However, after the crops are harvested, there will be straw and mulch in the farmland, which need to be processed separately before farming can be carried out.

[0038] The main components of ground film materials are polymer compounds. Under natural conditions, these polymers are difficult to decompose. The loss of production caused by a large amount of waste film pollution will exceed the yield increase benefits that can be brought by film planting. In the long run, the soil will be severely polluted, seriously affecting the growth and development of crops and eventually leading to the abandonment of cultivated land. In addition, if the waste film is directly discarded, it will also lead to a certain waste of resources. Therefore, after the crops are harvested, the waste film needs to be recycled and reused.

[0039] At present, a residual film picking and baling device is commonly used to recycle waste film. However, the residual film picking and baling device used in the related technology can only collect and remove waste film attached to the soil surface during operation, and the mulching seeder will bury the edge of the film into the soil in order to fix the film during operation, resulting in the residual film in the soil cannot be effectively recycled, which directly affects the waste film recycling efficiency.

[0040] In order to solve the above-mentioned problems, the present application proposes an integrated device for picking up and bundling residual film. The embodiments of the present application are further explained below in conjunction with the accompanying drawings.

[0041] Reference Figures 1 to 5The present application provides an integrated device for picking up and bundling residual film, including a traction frame 110, a frame 111, a film lifting mechanism, a film picking mechanism 130, a waste film winding mechanism 150 and a moving mechanism 112; the film lifting mechanism includes a film lifting frame 120, a plurality of film lifting rods 121 and a plurality of film lifting shovels, the film lifting rods 121 and the film lifting shovels are arranged one by one, the traction frame 110 is connected to the frame 111, the film lifting frame 120 is arranged at one end of the frame 111 close to the traction frame 110, one end of the plurality of film lifting rods 121 is movably arranged on the film lifting frame 120 in parallel and spaced apart, each film lifting shovel includes a shovel handle 122 and a shovel body 123, the shovel handle 122 is arranged at one end of the corresponding film lifting rod 121 away from the film lifting frame 120, one end of the shovel body 123 is connected to one end of the shovel handle 122 away from the film lifting rod 121, and the other end of the shovel body 123 is The shovel body 123 and the shovel handle 122 are integrally formed in a pointed shape, and the shovel body 123 is used to pick up the waste film buried in the soil along the edge; the waste film winding mechanism 150 is arranged at the rear end of the frame 111, and the film picking mechanism 130 is arranged between the film lifting frame 120 and the waste film winding mechanism 150, and the frame 111 is arranged on the moving mechanism 112; the film picking mechanism 130 includes a film picking belt assembly, a plurality of film picking rods 132 and at least four functional rollers, and the functional rollers are all arranged on the frame 111, and the film picking belt assembly is wrapped around each functional roller, and the film picking belt assembly is a polygonal ring structure, and a plurality of film picking rods 132 are uniformly arranged on the film picking belt assembly in sequence, and the film picking rods 132 and the film picking belt assembly form a toothed structure, and each functional roller is correspondingly provided with a drive motor, and the drive motor is connected to the corresponding functional roller, and the four functional rollers are axially parallel.

[0042] In the present application, the film-lifting shovel is fixed to the film-lifting rod 121 by the shovel handle 122, and the shovel body 123 is inserted into the ground to lift the waste film buried in the soil along the edge and expose it to the surface, so that the film picking mechanism 130 can pick up the waste film; the four functional rollers in the film picking mechanism 130 are combined with the film picking belt assembly and the film picking rod 132 to realize the picking, removal and removal of residual ground film and agricultural debris, and then the film picking operation is realized in a mechanized manner to improve the efficiency and effect of waste film picking; the waste film rewinding mechanism 150 is set to cooperate with the film picking mechanism 130 to realize the recovery of waste film and reduce the impact of residual ground film on crop planting; the traction frame 110 is connected to the external traction device, and the residual film picking and baling integrated device is driven by mechanical transmission, and the output is output by the rear output shaft of the traction device, and the whole machine works through conduction. The present application uses a film-lifting mechanism to lift the waste film on the ground so that the waste film on the ground can be more completely exposed on the surface, thereby improving the recovery rate of the waste film in the field, realizing a one-time operation of waste film recovery, and improving work efficiency.

[0043] In some embodiments, four film-lifting rods 121 are provided, and one end of the four film-lifting rods 121 is movably arranged side by side and spaced apart on the film-lifting frame 120. The number of shovel bodies 123 and shovel handles 122 corresponds to the number of film-lifting rods 121. The shovel handle 122 is provided with a threaded hole, and the bolt passes through the threaded hole and is screwed on the film-lifting rod 121 corresponding to the shovel handle 122. The film-lifting rod 121 is located at the bottom of the film-lifting frame 120, and the shovel handle 122 is detachably connected to the film-lifting rod 121, so that when the shovel body 123 is severely worn, the shovel body 123 is easily replaced. In other embodiments, the film-lifting rods 121 can also be set to other numbers, and the number of shovel bodies 123 and shovel handles 122 corresponds to the number of film-lifting rods 121, but is not limited to the embodiments of the present application.

[0044] It should be noted that the film-residual picking and bundling device is connected to an external traction device through the traction frame 110, and one end of the shovel body 123 is deeply embedded in the soil. As the traction device drives the film-lifting shovel to move, the waste film buried in the soil during the film-covered sowing process can be lifted out along the edge and exposed to the surface, which facilitates the operation of the film-residual picking and bundling device and improves the efficiency of film-residual recovery. In this embodiment, the traction device is a tractor.

[0045] It should be noted that the working process of the film picking mechanism 130 is to drive the operation of the film picking belt assembly through the operation of the four functional rollers, and then drive the operation of the film picking rod 132 to achieve the hooking and picking of the residual ground film.

[0046] It should be noted that the present application utilizes a film-lifting shovel to lift the film directly along the edge of the ground film, thereby avoiding the generation of broken film caused by cutting the film and ensuring the integrity of the film. The film-picking rod 132 cooperates with the film-lifting shovel to ensure that the residual film scooped up by the film-lifting shovel is continuously picked up by the film-picking rod 132 and transported to the film-picking belt assembly. In this process, since the residual film is relatively complete, the broken film is avoided from falling into the ground during the transfer process, thereby improving the recovery rate of the residual film. At the same time, in this process, the setting position and cooperation method of the film-picking rod 132 and the film-lifting shovel result in some impurities such as soil blocks and straw residues falling directly into the ground during the transfer process, thereby improving the recovery rate of the residual film and the quality of the recovered residual film, and the entire process is smooth, thereby improving the efficiency and stability of the separation of residual film recovery and debris.

[0047] Reference Figure 1 and Figure 3It can be understood that the residual film picking and bundling integrated device also includes a debris removal mechanism 140, which is arranged at the bottom end of the frame 111, and the debris removal mechanism 140 is arranged between the film starting frame 120 and the film picking mechanism 130, and the debris removal mechanism 140 includes a first transmission roller 141, a second transmission roller 142 and a debris conveyor belt, the first transmission roller 141 and the second transmission roller 142 are respectively arranged on both sides of the bottom end of the frame 111, and the debris conveyor belt is wrapped around the first transmission roller 141 and the second transmission roller 142.

[0048] Reference Figure 1 It can be understood that the integrated device for picking up and baling residual film also includes a returning-to-field pulverizing device 160, which is arranged between the traction frame 110 and the frame 111. The returning-to-field pulverizing device 160 is equipped with a conveying auger 161 which can discharge the pulverized straw to one side.

[0049] It should be noted that the crop straw on the film surface is crushed and discharged to one side by the returning-to-field crushing device 160, so as to facilitate the picking up of waste film. It should be noted that for cotton fields, sunflower fields and other farmlands with straw, the returning-to-field crushing device 160 is added to crush the straw in the farmland and discharge the crushed straw to one side by the conveying auger 161, so as to facilitate the picking up of waste film and realize the returning to the field under the conveying of the conveying auger 161.

[0050] It should be noted that by providing the return-to-field crushing device 160, the residual film picking and baling device of the present application integrates the functions of returning straw to the field and recovering residual film, and uses a set of equipment to complete the work of returning straw to the field and recovering residual film in one operation, thereby improving work efficiency.

[0051] It can be understood that the integrated device for picking up and bundling residual film further includes a spring tooth mechanism, which is disposed at the bottom end of the frame 111, and the debris removal mechanism 140 is disposed on the spring tooth mechanism.

[0052] In some embodiments, for corn fields, vegetable fields and other farmlands without straw, a spring tooth mechanism needs to be added at the bottom of the frame 111, so that when the ground is uneven, the added spring tooth mechanism can reach deeper into the ground and pick up the deeper ground film in the residual film picking and baling device; in other embodiments, a spring tooth mechanism is added at the bottom of the frame 111 in the residual film picking and baling device to which the field returning and crushing device 160 is added, and the embodiments of the present application are not limited here.

[0053] It is understandable that the installation angle between the shovel body 123 and the shovel handle 122 is between 30° and 150°.

[0054] It should be noted that when the installation angle of the shovel body 123 and the shovel handle 122 is greater than 90°, the contact area between the tip of the shovel body 123 and the soil is larger, which is convenient for removing the residual film in the soil; when the installation angle of the shovel body 123 is less than 90°, the contact area between the shovel body 123 and the soil is smaller, and the film-removing shovel receives less assistance during movement, which is convenient for the film-removing shovel to move.

[0055] In some embodiments, considering that the ground film is at the bottom of the ground surface and is in a shallow buried state, a smaller installation angle can be used to start removing the residual film. At the same time, considering the movement resistance and wear resistance of the film removing shovel, the installation angle of the shovel handle 122 is 45° to 90°.

[0056] Reference Figures 1 to 5 It can be understood that the four functional rollers are respectively a film picking roller 133, a de-dusting roller 134, a film stripping roller 135 and a tensioning roller 136. The film picking roller 133 is located below the de-dusting roller 134 and the film stripping roller 135, and the tensioning roller 136 is arranged between the film picking roller 133 and the de-dusting roller 134, or between the film picking roller 133 and the film stripping roller 135.

[0057] It should be noted that, by providing the tensioning roller 136, the film picking belt assembly can be tensioned to ensure the use effect of the film picking belt assembly.

[0058] It can be understood that a plurality of first annular de-impurifying grooves are provided in parallel on the roller surface of the de-impurifying roller 134, a plurality of annular demolding grooves are provided in parallel on the roller surface of the demolding roller 135, and the film picking belt assembly includes a plurality of film picking belts 131, and the plurality of film picking belts 131 pass through the corresponding first annular de-impurifying grooves of the de-impurifying roller 134 and the annular demolding grooves of the demolding roller 135; the diameter of the de-impurifying roller 134 is smaller than the diameter of the demolding roller 135, the depth of the first annular de-impurifying groove is smaller than the length of the film picking rod 132, and the length of the film picking rod 132 is smaller than the depth of the annular demolding groove.

[0059] It should be noted that when the film picking rod 132 hooks up the residual ground film, the residual film is generally hung on the end of the film picking rod 132. At the same time, the remaining crop branches and leaves, mixed soil and other agricultural debris are hooked up by the film picking rod 132 and are generally hooked on the rod body of the film picking rod 132. With the operation of the film picking belt assembly, the film picking rod 132 first passes through the tensioning roller 136 and passes through the tensioning roller 136. Subsequently, the film picking rod 132 passes through the de-weeding roller 134 and passes through the first annular de-weeding groove of the de-weeding roller 134. At this time, since the depth of the first annular de-weeding groove is less than the length of the film picking rod 132, the film picking rod 132 is hung on the film picking rod 1 The residual film at the end of 32 is not removed, and only the impurities on the rod body of the film picking rod 132 are removed; as the film picking belt 131 continues to operate, the film picking rod 132 passes through the annular film stripping groove of the film stripping roller 135. At this time, since the length of the film picking rod 132 is less than the depth of the annular film stripping groove, the residual film hooked on the film picking rod 132 falls off; during the operation of the film picking belt 131, the tensioning roller 136 always tensions the film picking belt 131 to ensure the use effect of the film picking belt 131; by adding a waste film winding mechanism 150 at the rear end of the film picking device, the fallen residual film can be recovered.

[0060] It can be understood that the film picking mechanism 130 also includes a de-dusting cylinder 137, which is arranged on the frame 111 and located between the film picking roller 133 and the de-dusting roller 134. A second annular de-dusting groove is provided on the arc-shaped roller surface of the de-dusting cylinder 137. The depth of the second annular de-dusting groove is less than the length of the film picking rod 132. The film picking belt 131 bypasses the corresponding second annular de-dusting groove of the de-dusting cylinder 137.

[0061] It should be noted that, since the depth of the second annular impurity-removing groove is less than the length of the film-picking rod 132, the film-picking rod 132 that first passes through the impurity-removing cylinder 137 uses the second annular impurity-removing groove of the impurity-removing cylinder 137 to preliminarily remove impurities. In addition, the position of the impurity-removing cylinder 137 on the frame 111 is adjustable, that is, by adjusting the position of the impurity-removing cylinder 137 on the frame 111, the distance between the impurity-removing semicircular cylinder and the impurity-removing roller 134 can be adjusted.

[0062] It should be noted that by providing the de-impurity cylinder 137, the de-impurity effect is effectively improved.

[0063] Reference Figures 1 to 3It can be understood that the waste film winding mechanism 150 includes a first waste film recovery roller 152, a second waste film recovery roller 153, a conveyor belt 154, a waste film packaging frame 151 and a waste film recovery reel 155. The first waste film recovery roller 152, the second waste film recovery roller 153 and the waste film recovery reel 155 are all arranged on the waste film packaging frame 151, the first waste film recovery roller 152 and the film stripping roller 135 are arranged side by side, the conveyor belt 154 is respectively wound around the film stripping roller 135, the first waste film recovery roller 152 and the second waste film recovery roller 153, the conveyor belt 154 is a triangular structure, and the waste film recovery reel 155 is used to collect the waste film from the film picking belt assembly.

[0064] It should be noted that the first waste film recovery roller 152, the second waste film recovery roller 153, the film stripping roller 135 and the conveyor belt 154 cooperate with each other to convey the waste film picked up by the film picking mechanism 130 to the waste film recovery reel 155 for recovery.
