[0062] Specifically, the depth-limiting wheel 32 is a cylindrical structure, with an open end on one side and a closed end on the other side; a through hole rotatably connected to the support beam 33 is arranged at the center of the closed end; and the open end is located outside the frame. The depth-limiting wheel 32 is used for the whole machine to travel in the cultivated land.

[0063] Specifically, the support beam 33 is a bent structure, one end of the support beam 33 is vertically connected to the front end of the frame 1 ; the other end of the support beam 33 is rotatably connected to the limited depth wheel 32 .

[0064] Specifically, one end of the support frame 34 is a block structure, which is connected to the top of the support beam 33 by bolts; the other end of the support frame 34 is a U-shaped frame structure, and the size of this frame structure matches the size of the crossbeam at the front end of the frame 1 so that the U-shaped frame structure of the support frame 34 can be connected to the crossbeam of the frame 1 by clamping. By adjusting the position of the bolts connecting the support frame 34 to the support beam 33, the connection height between the support beam 33 and the frame 1 can be adjusted, thereby adjusting the depth of the walking film cutting mechanism 3 into the soil.

[0065] like Figure 5 As shown, preferably, the film-lifting mechanism 4 includes a film-lifting scraper 41 , an arc-shaped film-turning rod 42 and a film-lifting scraper arm 43 .

[0066] The film lifting shovel arm 43 is fixedly connected to the frame 1; the film lifting shovel blade 41 is vertically connected to the film lifting shovel arm 43; one side of the film lifting shovel blade 41 is connected to an arc-shaped film-turning rod 42 for shoveling up the ground film.

In this embodiment, three arc-shaped film-turning rods 42 are provided, and the three arc-shaped film-turning rods 42 are evenly spaced along the length direction of one end of the fixed plate 411, and the height values ​​gradually increase. Each arc-shaped film-turning rod 42 is a multi-segment rod-shaped structure, and each arc-shaped film-turning rod 42 is obliquely connected to the fixed plate 411, and is used to shovel up the ground film.

[0071] A plurality of circular holes are provided on the side of the film shovel arm 43 away from the fixed plate 411, and the plurality of circular holes are evenly spaced along the length direction of the film shovel arm 43. The film shovel arm 43 and the frame 1 can be detachably connected by bolts through the circular holes, and the height of the film shovel arm 43 relative to the frame 1 can be adjusted through the plurality of circular holes.

The film scraper 41 is used to shovel the divided ground film off the ground, and the arc film guide rod 42 is used to support and guide the ground film, so as to prevent the ground film from being broken during the subsequent film twisting process.

[0073] like Figure 6 and Figure 7 As shown, the belt-type film twisting device includes two first belt-type film twisting devices 6 and one second belt-type film twisting device 7. In this embodiment, the two first belt-type film twisting devices 6 are distributed in a horizontal line and are separated by a preset distance. The second belt-type film twisting device 7 is located in the middle of the rear side of the two first belt-type film twisting devices 6, so that when the sheet-like ground film is output as two rope-like ground films through the two first belt-type film twisting devices 6 and transported to the second belt-type film twisting device 7, the two rope-like ground films can be twisted into one rope-like ground film again.

[0074] like Figure 6 and Figure 7 As shown, preferably, the first belt-type film twisting device 6 includes a first fixing frame 61, a first film twisting recovery device, a first auxiliary positioning device and a first driving device.

[0076] The first twist film recovery device includes a first twist film recovery transmission shaft 62, a first twist film recovery roller 63 and a first twist film recovery belt 64; the top and bottom of the first fixed frame 61 are symmetrically rotatably connected to the first twist film recovery transmission shaft 62, the first twist film recovery roller 63 is sleeved on the outside of the first twist film recovery transmission shaft 62, and the first twist film recovery belt 64 is sleeved on the outside of the two first twist film recovery rollers 63; the first driving device is connected to the first twist film recovery transmission shaft 62, and is used to drive the first twist film recovery belt 64 to rotate.

[0078] Specifically, the inner sides of the two vertical frames are respectively used to symmetrically connect two first twist film recovery transmission shafts 62 separated by a preset distance, and the outer side of each first twist film recovery transmission shaft 62 is connected to a first twist film recovery roller 63, and the first twist film recovery roller 63 rotates synchronously under the rotation of the first twist film recovery transmission shaft 62. The outer sides of the two first twist film recovery rollers 63 on one side of the vertical frame are connected to the first twist film recovery belts 64.

[0079] like Figure 6 As shown, the first belt-type film twisting device 6 on the right side of the figure has the same structure as the first belt-type film twisting device 6 on the left side of the figure. Figure 6 The first belt-type film twisting device on the left side is described in detail.

[0080] Specifically, Figure 6 As shown, in the vertical frame on the left side of the first fixed frame 61 of the first belt-type film twisting device 6 on the left side, the top and bottom ends of the vertical frame are symmetrically connected to the first film twisting recovery transmission shaft 62, and the first film twisting recovery rollers 63 are respectively sleeved on the two first film twisting recovery transmission shafts 62. The top end of the first film twisting recovery belt 64 is connected to the first film twisting recovery roller 63 at the top of the vertical frame, and the bottom end of the first film twisting recovery belt 64 is connected to the first film twisting recovery roller 63 at the bottom of the vertical frame. The rotation of the two first film twisting recovery transmission shafts 62 rotatably connected on the left vertical frame drives the two first film twisting recovery rollers 63 on the two first film twisting recovery transmission shafts 62 to rotate, thereby realizing the rotation of the first film twisting recovery belt 64 on the vertical frame on the left side of the first fixed frame 61 of the first belt-type film twisting device 6 on the left side.

[0081] Specifically, Figure 6 As shown, in the vertical frame on the right side of the first fixed frame 61 of the first belt-type film twisting device 6 on the left side, the top and bottom ends of this vertical frame are symmetrically connected to the first film twisting recovery transmission shaft 62, and the outer sides of the two first film twisting recovery transmission shafts 62 are respectively sleeved with the first film twisting recovery rollers 63, the top end of the first film twisting recovery belt 64 of this vertical frame is connected to the first film twisting recovery roller 63 at the top of this vertical frame, and the bottom end of the first film twisting recovery belt 64 of this vertical frame is connected to the first film twisting recovery roller 63 at the bottom of this vertical frame, and the first film twisting recovery belts 64 on the left and right vertical frames of the first fixed frame 61 of the first belt-type film twisting device 6 on the left side have the same transmission speed but opposite transmission directions, so as to subject the two sides of the sheet-like ground film between the first film twisting recovery belts 64 on both sides of the first fixed frame 61 to opposite forces and twist them into ropes.

[0082] Preferably, the first belt-type film twisting device 6 further includes a first auxiliary positioning device, which is connected to the front side of the first fixing frame, and includes a first auxiliary positioning film twisting shaft 65, a first auxiliary positioning film twisting roller 66, a second auxiliary positioning film twisting roller 67 and a second auxiliary positioning film twisting shaft 68;

[0083] The first auxiliary positioning film twist shaft 65 and the second auxiliary positioning film twist shaft 68 are symmetrically connected to the front side of the first fixed frame; the outer side of the first auxiliary positioning film twist shaft 65 is sleeved with the first auxiliary positioning film twist roller 66, and the outer side of the second auxiliary positioning film twist shaft 68 is sleeved with the second auxiliary positioning film twist roller 67.

[0084] Specifically, Figure 6 As shown, the front end of the first fixed frame 61 is connected with the first auxiliary positioning film twist shaft 65 and the second auxiliary positioning film twist shaft 68, the first auxiliary positioning film twist shaft 65 and the second auxiliary positioning film twist shaft 68 are parallel and separated by a preset distance; the first auxiliary positioning film twist shaft 65 is connected to the first auxiliary positioning film twist roller 66, and the second auxiliary positioning film twist shaft 68 is connected to the second auxiliary positioning film twist roller 67; and, a channel for passing the sheet ground film is reserved between the first auxiliary positioning film twist roller 66 and the second auxiliary positioning film twist roller 67, so as to transport the sheet ground film to the first twist film recovery device and twist it into a rope-shaped ground film.

[0085] Specifically, the ends of the first auxiliary positioning film twisting shaft 65 and the second auxiliary positioning film twisting shaft 68 are rotatably connected to the bearing seat through bearings, and the bearing seat is connected to the front end of the first fixing frame 61 to achieve the support function of the first auxiliary positioning film twisting shaft 65 and the second auxiliary positioning film twisting shaft 68;

[0086] In addition, the bearing seat and the first fixed frame 61 can be slidably connected in the form of a guide rail and a slider, so that the bearing seat can slide within a certain range in the up and down directions relative to the first fixed frame 61. The purpose is to ensure the best position of the film twisting. Because the friction force generated by the film twisting belt during the film twisting process will cause the ground film to deviate up and down, in order to control the film twisting range within a certain area and ensure the smooth progress of the film twisting, the film twisting is in a better position.

[0087] In this embodiment, the first driving device includes: a first motor 75 , a first motor driving pulley 76 , a first transmission belt 77 and a first twist film recovery driven pulley 78 .

[0088] Among them, a first motor 75 is connected to the outer bottom of each vertical frame, and the first motor 75 is connected to the first motor driving pulley 76. The first motor driving pulley 76 is connected to the first twist film recovery driven pulley 78 through a first transmission belt 77. The first motor 75 drives the first motor driving pulley 76 to rotate to drive the first transmission belt 77 to rotate, thereby driving the first twist film recovery driven pulley 78 to rotate. Since the first twist film recovery driven pulley 78 is fixedly connected to the first twist film recovery transmission shaft 62, the rotation of the first twist film recovery transmission shaft 62 is realized.

[0089] like Figure 6 and Figure 7As shown, the second belt-type film twisting device 7 is located in the middle of the rear side of the two first belt-type film twisting devices 6. The second belt-type film twisting device 7 and the two first belt-type film twisting devices 6 form a triangle shape, and the distance between the second belt-type film twisting device 7 and the two first belt-type film twisting devices 6 is equal. Each first belt-type film twisting device 6 outputs a rope-shaped ground film, and the two rope-shaped ground films output by the two first belt-type film twisting devices 6 are gathered in the second belt-type film twisting device 7 to be twisted into a rope-shaped ground film, thereby greatly compressing the volume of the sheet-shaped ground film and reducing the occupied space.

[0096] like Figure 7In the orientation shown, a second motor 83 is provided on the outer side surface of the bottom of the left vertical frame of the second fixed frame 80 and the right vertical frame of the second fixed frame 80, the second motor 83 is connected to the second motor driving pulley 84, one end of the second twist film recovery transmission shaft 79 is connected to the second twist film recovery driven pulley 86, the second motor driving pulley 84 and the second twist film recovery driven pulley 86 are connected by a second transmission belt 85, the second motor driving pulley 84 is driven to rotate by the second motor 83, the second motor driving pulley 84 rotates to drive the second transmission belt 85 to rotate, the second transmission belt 85 rotates to drive the second twist film recovery driven pulley 86 to rotate, thereby driving the second twist film recovery transmission shaft 79 to rotate.

[0099] like Figure 8 The motion tracks of the first twist film recovery device and the second twist film recovery device shown in the figure are described according to the orientation shown in the figure. The motion direction of the first twist film recovery belt 64 on the left vertical frame in the first twist film recovery device on the left is opposite to the motion direction of the first twist film recovery belt 64 on the right vertical frame, so as to achieve the first twist film recovery belts 64 on the two vertical frames in the first twist film recovery device on the left rotating in opposite directions to twist the sheet-like ground film into a rope-like ground film;

[0100] Similarly, the movement direction of the first twist film recovery belt 64 on the left side of the vertical frame on the left side of the first twist film recovery device located on the right side in the figure is opposite to the movement direction of the first twist film recovery belt 64 on the vertical frame on the right side. The purpose is to achieve the opposite rotation directions of the first twist film recovery belts 64 on the two vertical frames in the first twist film recovery device located on the right side so as to twist the sheet-like ground film into a rope-like ground film.

[0101] Similarly, the movement direction of the second twist film recovery belt 82 in the left vertical frame of the second twist film recovery device located behind the two first twist film recovery devices in the figure is opposite to that of the second twist film recovery belt 82 in the right vertical frame, and the second twist film recovery belt 82 in the vertical frame on the left side of the second twist film recovery device is opposite to the rotation direction of the first twist film recovery belt 64 in the vertical frame on the left side of the first twist film recovery device, and the second twist film recovery belt 82 in the vertical frame on the right side of the second twist film recovery device is opposite to the rotation direction of the first twist film recovery belt 64 in the vertical frame on the right side of the first twist film recovery device. The purpose is to achieve that the two strands of rope-shaped ground film output from the two first twist film recovery devices are twisted into a rope-shaped ground film between the two second twist film recovery belts 82 of the second twist film recovery device.

[0102] It is worth noting that the distance between the two second twist film recovery belts 82 of the second twist film recovery device is greater than the distance between the two first twist film recovery belts 64 of the first twist film recovery device to accommodate the two rope-shaped ground films output from the first twist film recovery device.

[0105] Specifically, the ends of the third auxiliary positioning film twisting shaft 71 and the fourth auxiliary positioning film twisting shaft 73 are rotatably connected to the bearing seat through bearings, and the bearing seat is connected to the front end of the second fixing frame 80 to achieve the support function of the third auxiliary positioning film twisting shaft 71 and the fourth auxiliary positioning film twisting shaft 73;

[0106] In addition, the bearing seat and the second fixed frame 80 can also be slidably connected in the form of a guide rail and a slider, so that the bearing seat can slide within a certain range in the up and down directions relative to the first fixed frame 61, in order to ensure the optimal position of the film twisting. Because the friction generated by the film twisting belt during the film twisting process will cause the ground film to deviate up and down, in order to ensure the smooth progress of the film twisting, it is necessary to control the film twisting within a certain area. By setting a third auxiliary positioning film twisting shaft 71 and a fourth auxiliary positioning film twisting shaft 73 that are parallel to each other and can move relative to each other, the film twisting can be controlled at the optimal position.

When the distance between the first movable arm 94 and the second movable arm 95 increases, the tips of the first cone roller 91 and the second cone roller 92 are separated, and the rope-like ground film wound between the first cone roller 91 and the second cone roller 92 is taken out for collection; when the rope-like ground film needs to be wound, the hydraulic cylinder 5 is retracted to shorten the distance between the first movable arm 94 and the second movable arm 95, and the tips of the first cone roller 91 and the second cone roller 92 are docked for winding the rope-like ground film.
