[0038] like Figures 1 to 5 As shown, the present application provides a device 1 for lifting and removing soil from an edge film, comprising:

[0039] Bracket 11;

[0040] A soil loosening and ditching portion 12, the soil loosening and ditching portion 12 is connected to the first side of the bracket 11 and is disposed close to the first end of the bracket 11, and the soil loosening and ditching portion 12 has a concave streamlined curved surface structure;

[0041] A loose lifting portion 13 is connected to the second side of the bracket 11 which is opposite to the first side of the bracket 11, and is located at the second end of the bracket 11 which is opposite to the first end. The loose lifting portion 13 has a curved surface structure inclined toward the first side of the bracket 11, a groove structure is formed between the curved surface structure and the bracket 11, and the curved surface structure also forms a guide channel toward the first side of the bracket 11 with the gap of the bracket 11.

[0042] The present application provides a device 1 for lifting and removing soil from an edge film, and the present application provides a device 1 for lifting and removing soil from an edge film, comprising a bracket 11, a soil loosening and ditching part 12, and a loosening and lifting part 13. The bracket 11 has a first side and a second side arranged opposite to each other, the first side is provided with the soil loosening and ditching part 12, and the second side is provided with the loosening and lifting part 13. The bracket 11 also has a first end and a second end arranged opposite to each other, and the connecting direction of the first side and the second side of the bracket 11 is perpendicular to the connecting direction of the first end and the second end of the bracket 11, the soil loosening and ditching part 12 is located at the first end of the bracket 11, and the loosening and lifting part 13 is located at the second end of the bracket 11. When the edge membrane structure is removed by the edge touch lifting and soil removal device, the loosening and ditching part 12 at the first end of the bracket 11 is first inserted into the soil, and the concave streamlined curved surface structure in the loosening and ditching part 12 can open a groove in the left front of the curled part of the edge membrane structure to destroy the bottom of the edge membrane structure and make the edge membrane initially unstable, and then the loosening and lifting part 13 is inserted into the soil for operation, and the insertion position of the loosening and lifting part 13 corresponds to the position below the edge membrane structure, so that the loosening and lifting part 13 will cut and loosen the soil below the curled part of the edge membrane, and as the machine moves forward, the cut soil moves along with the loosening and lifting part 1 The curved surface structure formed between the edge membrane structure 3 and the support 11 is lifted to a certain height, and through the outlet channel formed between the curved surface structure and the support 11 and toward the first side of the support 11, the soil lifted by the loose lifting part 13 can be turned over to the side of the groove opened by the loose soil ditching part 12 through the outlet channel, so as to achieve the purpose of removing the soil on the membrane, and then release the buckling structure formed by the edge membrane structure and the soil, so as to achieve the destruction of the edge membrane structure, so as to facilitate the recovery of the edge membrane while recovering the residual film on the surface, avoiding the problem that the edge membrane cannot be recovered together with the residual film on the surface.

[0043] like Figure 1 As shown, in the embodiment of the present application, the lowest point of the loosening and lifting part 13 is higher than the highest point of the loosening and ditching part 12.

[0044] In some embodiments, the loosening and lifting part is located at the right rear of the loosening and ditching part 12. After the loosening and ditching part 12 has opened a ditch on the left side of the edge film part, the loosening and lifting part 13 enters the soil below the edge film structure. Since the loosening and ditching part 12 is lower than the loosening and lifting part 13, the depth of the groove opened by the loosening and ditching part 12 in the left front of the edge film structure is deeper. The groove formed by the loosening and ditching part 12 and the edge film structure can form a sufficiently high height difference, so that the soil lifted by the loosening and lifting part 13 can be buckled into the groove opened by the loosening and ditching part 12 through the outlet channel, thereby ensuring that the loosening and ditching part 12 can continue to move forward, and then realize the release of the buckling structure formed by the edge film structure and the soil, so that the edge film can be taken up and recycled while the residual film on the surface is recovered. At the same time, a certain distance is made between the top of the loosening and lifting part 13 and the field ridge to avoid the problem of the soil on the film moving in the opposite direction of the ditch bottom due to lifting too high.

[0045] like Figures 1 to 5 As shown, in the embodiment of the present application, the portion of the soil loosening and ditching portion 12 close to the first end of the bracket 11 has a sharp corner; the portion of the soil loosening and ditching portion 12 away from the first end of the bracket 11 to the portion close to the first end of the bracket 11 gradually approaches the bracket 11 along the direction from the first side of the bracket 11 to the second side.

[0046] In some embodiments, the part of the loosening and ditching part 12 close to the first end of the bracket 11 has a sharp corner, so that it is more labor-saving when the loosening and ditching part 12 is used to ditch the left side of the edge membrane structure. There is a preset distance between the part of the loosening and ditching part 12 far from the first end of the bracket 11 and the bracket 11, and the part of the loosening and ditching part 12 close to the first end of the bracket 11 fits with the bracket 11, so that the part of the loosening and ditching part 12 far from the first end of the bracket 11 to the part close to the first end of the bracket 11 gradually approaches the bracket 11 along the direction from the first side to the second side of the bracket 11, so as to form a streamlined curved surface structure to ditch the soil on the left side of the edge membrane structure, and move the soil to the left side of the loosening and ditching part 12, so as not to cause accumulation on the edge membrane structure on the right side.

[0047] like Figures 1 to 5 As shown, in the embodiment of the present application, the streamlined curved surface structure of the loosening and lifting portion 13 is an arc-shaped structure away from the tail wing 131 of the loosening and ditching portion 12;

[0048] The edge of the derivation channel is a smooth structure with a downward trend.

[0049] In some embodiments, when the loose lifting part 13 extends into the soil to lift the lower part of the edge film structure, the tail 131 of the loose lifting part 13 is an arc-shaped structure, so that the loose lifting part 13 can avoid tearing the edge film during the lifting process, thereby causing the problem of residual edge film. The gap between the loose lifting part 13 and the bracket 11 forms an outlet channel, and the edge of the outlet channel is adjacent to the gap of the bracket 11. The edge of the outlet channel is a smooth structure with a downward trend, so that the soil lifted by the loose lifting part 13 has a better outlet trend in the outlet channel, and it is more convenient for the soil to enter the groove formed by the loose soil ditching part 12.

[0050] like Figures 1 to 4 As shown, in the embodiment of the present application, there is a gap between the first end and the second end of the bracket 11, and the curved surface structure of the loose lifting portion 13 and the gap between the first end and the second end of the bracket 11 form an outlet channel.

[0051] In some embodiments, the first bracket 11 includes a first column 112, a second column 113 and a connecting rod 114, the first column 112 and the second column 113 are arranged in parallel or approximately in parallel, the two ends of the connecting rod 114 are respectively connected to the first end of the first column 112 and the first end of the second column 113, and the connecting rod 114 is arranged vertically or approximately vertically to the first column 112 and the second column 113, so that the bracket 11 forms a door-like structure, the area between the first column 112 and the second column 113 is a first gap 111, the first side of the first column 112 is connected to the loose soil ditching part 12, and the second side of the second column 113 is connected to the loosening lifting part 13. Therefore, the loose soil ditching part 12 and the loosening lifting part 13 are arranged on the first side and the second side of the bracket 11, respectively. There is a gap between the first end and the second end of the bracket 11. After the loosening and lifting part 13 is put into the soil and lifts the soil to a certain height, the soil will be introduced into the groove formed by the loosening and ditching part 12 through the outlet channel formed by the curved surface structure and the gap between the first end and the second end of the bracket 11, so as to achieve the purpose of removing the soil on the membrane, and then release the locking structure formed by the edge membrane structure and the soil, thereby achieving the destruction of the edge membrane structure.

[0052] like Figure 4 As shown, in the embodiment of the present application, at least part of the streamlined curved surface structure of the loose lifting portion 13 is arranged opposite to the first gap 111 formed between the first end and the second end of the bracket 11, and the streamlined curved surface structure of the loose lifting portion 13 and the first gap 111 area form a first outlet channel 132.

[0053] In one embodiment of the present application, the gap between the first end and the second end of the bracket 11, the streamlined curved surface structure of the partially loose lifting part 13 and the second column 113 are arranged correspondingly, and the streamlined curved surface structure of the partially loose lifting part 13 and the partially first gap are arranged correspondingly, thereby forming a first outlet channel 132, and the outlet channel is the first outlet channel 132. After the loose lifting part 13 is put into the soil to lift the soil to a certain height, the soil will be better removed through the first outlet channel 132, so as to achieve the purpose of removing the soil on the membrane, and then release the buckle structure formed between the edge membrane structure and the soil.

[0054] like Figures 1 to 3 As shown, in the embodiment of the present application, at least part of the streamlined curved surface structure of the loose lifting portion 13 is arranged opposite to the second gap 115 area on the second end of the bracket 11 away from the first end, the streamlined curved surface structure of the loose lifting portion 13 and the second gap 115 area form a second outlet channel 133, and the streamlined curved surface structure of the loose lifting portion 13 close to the edge of the first gap 111 and the first gap 111 area form a third outlet channel 134.

[0055] In another embodiment of the present application, the gap between the first end and the second end of the bracket 11, the streamlined curved surface structure of the partially loose lifting part 13 is arranged corresponding to the second column 113, and the streamlined curved surface structure of the partially loose lifting part 13 is arranged corresponding to the second gap, thereby forming a second outlet channel 133. In addition, the gap between the first end and the second end of the bracket 11 and the streamlined curved surface structure of the loose lifting part 13 form a third outlet channel 134 near the edge of the first gap 111. At this time, the outlet channels are the second outlet channel 133 and the third outlet channel 134. Therefore, after the loose lifting part 13 is buried in the soil and lifts the soil to a certain height, the soil can be better removed through the third outlet channel 134 and the second outlet channel 133 formed in the gap between the first end and the second end, thereby achieving the purpose of removing the soil on the membrane, and then releasing the buckling structure formed between the edge membrane structure and the soil.

[0056] In the embodiment of the present application, there is no gap between the first end and the second end of the bracket 11, and at least a portion of the streamlined curved surface structure of the loose lifting portion 13 is arranged relative to the second gap 115 area on the side of the second end of the bracket 11 away from the first end, and the streamlined curved surface structure and the second gap 115 area form a second outlet channel 133.

[0057] like Figure 5As shown, in another embodiment of the present application, there is no gap between the first end and the second end of the bracket 11, that is, the bracket 11 is a plate-like structure, at this time, the first side of the first end of the bracket 11 is connected to the loose soil ditching part 12, and the second side of the second end of the bracket 11 is connected to the loose lifting part 13, and at least part of the streamlined curved surface structure of the loose lifting part 13 is arranged relative to the second gap 115 area on the side of the second end of the bracket 11 away from the first end to form a second outlet channel 133, and the outlet channel is the second outlet channel 133. Therefore, after the loose lifting part 13 is buried in the soil and lifts the soil to a certain height, the soil will be removed through the second outlet channel 133, which achieves the purpose of removing the soil on the membrane, and then releases the buckling structure formed between the edge membrane structure and the soil.

[0058] In the embodiment of the present application, the angle between the streamlined curved surface structure of the loose lifting portion 13 and the bracket 11 is an acute angle;

[0059] The angle between the streamlined curved surface structure of the loosening and ditching part 12 and the bracket 11 is an acute angle.

[0060] In some embodiments, the loose lifting portion 13 can be integrally formed with the bracket 11, and the loose lifting portion 13 can also be fixed to the bracket 11 by welding or other means. The streamlined curved surface structure of the loose lifting portion 13 and the bracket 11 form an acute angle, so that the soil under the side membrane structure can be better excavated and lifted after extending into the soil, thereby avoiding the problem of soil escaping from the right side of the side membrane structure due to the excessively large angle between the loose lifting portion 13 and the bracket 11.

[0061] In this embodiment, the specific angle of penetration of the loose lifting portion 13 into the soil, the opening angle of the streamlined curved surface structure and the rebate angle formed by the streamlined curved surface structure and the bracket 11 are determined according to requirements and actual conditions, as long as the requirements are met.

[0062] In some embodiments, the soil loosening and ditching portion 12 has a pointed structure near the first end of the bracket 11, and the pointed structure has a first side and a second side. The first end of the bracket 11 has a smooth arc that matches the soil loosening and ditching portion 12, and the arc has a recess. The first side is fixedly connected to the smooth arc at the first end of the bracket 11, and can be welded or connected by a splint and bolted. The second side is not connected to the bracket 11. In addition, the side of the soil loosening and ditching portion 12 that is away from the first end of the bracket 11 is away from the bracket 11, and is fixedly connected to the bracket 11 through a connecting rod, which can be welded.

[0063] On the other hand, the present application also provides a surface residual film recovery mechanism, including the edge film lifting and soil removal device 1 as described above. All the technical features and beneficial technical effects of the edge film lifting and soil removal device 1 as described above are included, and no further description is given here. The surface residual film recovery mechanism is provided with an edge film lifting and soil removal device, so that while recovering the surface residual film, the edge film lifting and soil removal can be performed to achieve the recovery of the surface residual film.
