DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0034] The utility model provides a kind of adjustable ridge ditch residual film pickup machine as shown in Figs. 1-3 It is the front inside structure schematic view of the film cutting adjusting mechanism.

[0035] Specifically, the automatic profiling film uncovering mechanism 3 comprises a first connecting rod 31, a film uncovering spring tooth 32 and a tension spring 33. The first connecting rod 31 is fixedly connected to the bottom end of the rack 1 at equal intervals. The film uncovering spring tooth 32 is installed on the bottom end of the first connecting rod 31 at equal intervals through screws. One end of the tension spring 33 is fixedly connected to the rack 1, and the other end of the tension spring 33 is fixedly connected to the first connecting rod 31. The fixed film cutting disc 5 and the movable film cutting disc 6 cut the mulch film from the ditch and the film edge. The film uncovering spring tooth 32 can separate the residual film from the ground. As the amount of accumulated residual film increases, the tension spring 33 is stretched, the film uncovering spring tooth 32 moves backward, the residual film is placed on the ground, the tension spring 33 resets, and the residual film placed on the ground is picked up by the film picking tooth 2. As the picked-up mulch film in the film picking tooth 2 reaches the maximum, the tractor is operated to pull the residual film to the field edge to unload, and the above work is repeated to complete the film picking work.

[0036] Specifically, the film cutting adjusting mechanism 4 comprises a linear guide rail 41, a moving plate 42, a connecting shaft 43, a second connecting rod 44, a linear reciprocating motor 45 and a push rod 46. The linear guide rail 41 is fixedly installed on the top end of the rack 1. The moving plate 42 is symmetrically and slidably arranged on the linear guide rail 41. The movable film cutting disc 6 is fixedly installed on the outer wall of the moving plate 42. The connecting shaft 43 is rotatably arranged in the interior of the linear guide rail 41. One end of the second connecting rod 44 is rotatably connected to the moving plate 42, and the other end of the second connecting rod is rotatably connected to the connecting shaft 43. The linear reciprocating motor 45 is fixedly installed on the rack 1. The output end of the linear reciprocating motor 45 is in transmission connection with one end of the push rod 46. The other end of the push rod 46 is fixedly connected to the moving plate 42. The push rod 46 is displaced by the linear reciprocating motor 45, so that the plurality of moving plates 42 adjust the movable film cutting disc 6 to reach the position of the ridge ditch through the second connecting rod 44. Then the fixed film cutting disc 5 and the movable film cutting disc 6 are adjusted to a certain height. After checking the working condition of the whole machine, the tractor is started, and the fixed film cutting disc 5 and the movable film cutting disc 6 cut the mulch film from the ditch and the film edge.

[0037] Further, the top end of the rack 1 is fixedly connected with a suspension frame 7 for suspension behind the tractor. The suspension frame 7 is provided with holes and grooves for connection with the rear of the tractor, facilitating power supply through the tractor to achieve cutting and picking of the mulch film.

[0038] Further, sleeves 8 are fixedly installed on both sides of the rack 1. Telescopic rods 9 are slidably connected in the inner cavities of the sleeves 8. Limiting depth wheels 10 are rotatably arranged on the telescopic rods 9 for contacting the ground. Fixed bolts 11 are threadedly inserted into the outer walls of the sleeves 8 for adjusting the telescopic length of the telescopic rods 9. The telescopic length of the telescopic rods 9 can be adjusted through the fixed bolts 11, so that the limiting depth wheels 10 can adjust the height of the whole rack 1, facilitating the fixed film cutting disc 5 and the movable film cutting disc 6 to cut the mulch film from the ditch and the film edge, and facilitating use.
