Description

Technical Field

[0001] The utility model belongs to the technical field of ground film laying devices, and in particular relates to a ground film laying device for sunken cultivated land. Background Art

[0002] Land mulching, also known as mulching, refers to an agricultural technical measure to lay a certain type of covering material or film on the surface of cultivated land during the crop growing season. Specifically, mulching is a water-saving agricultural technology model that covers the ground with agricultural plastic film to achieve comprehensive effects such as rainwater collection, moisture conservation, temperature increase, and weed suppression. The mulching technology is widely used because of its multiple advantages such as heat preservation, moisture retention, weed prevention, and promotion of crop growth. However, in actual operation, after the ground is covered with mulch, if it rains near the field, the rainwater cannot pass through the mulch into the soil due to the mulch blocking it, which can easily lead to soil compaction in the sowing row. In addition, the traditional device covers the ground on both sides of the mulch with soil, and the wind resistance is relatively poor. Utility Model Content

[0023] Please refer to Figures 1-6 as shown, the present utility model provides the following technical solutions:

[0024] A device for laying plastic film on sunken cultivated land includes two moving moving members 2 and a traction member 1 for dragging the moving members 2 to move along a preset path. A film covering member 3 for laying plastic film is installed between the two moving members 2. The film covering member 3 includes a feeding part for supplying plastic film and a film covering roller 310. The film covering roller 310 is rotatably connected to the side of the feeding part away from the traction member 1. Two connecting plates 313 are symmetrically and fixedly connected to the side of the feeding part away from the traction member 1. The bottoms of the two connecting plates 313 are rotatably connected with runners 314. The outer circumference of the runner 314 is convexly fixedly connected with a plurality of first punching heads 36. The film covering roller 310 is located between the feeding part and the runner 314.

[0025] Through the above technical scheme, when personnel need to lay ground film on cultivated land, they pull the ground film on the feeding part, and then pass the initial section of the ground film under the film coating roller 310, and cover the initial section of the ground film on the initial section of the cultivated land, and cover the soil on the ground film, connect the traction vehicle with the traction member 1, pull the traction member 1 through the traction vehicle, and drive the moving member 2 to move through the traction member 1. When the moving member 2 moves, it will synchronously drive the film coating roller 310 to rotate, so as to cover the film coating roller 310 on the cultivated land, and when the film coating roller 310 rotates, it will synchronously drive the rotating wheel 314 to rotate, and drive the first punching head 36 to rotate through the rotating wheel 314, and then punch holes in the ground film, so that rainwater can easily enter the soil through the ground film, so that the soil in the sowing row is not easy to be compacted.

[0026] In order to cover the middle part of the ground film with soil, Figures 1-4 and Figure 6 As shown, the circumference of the coating roller 310 is sunken to form a soil covering groove 311, and the circumference of the soil covering groove 311 is in a circular array with two second punching heads 312 equidistantly connected thereto, and the second punching heads 312 are located between two adjacent soil covering grooves 311.

[0027] In this embodiment, when the film covering roller 310 rotates, the second punching head 312 on the soil covering groove 311 cooperates to drive the soil to be turned over, so that the soil covers the middle position of the ground film, thereby reinforcing the ground film and punching holes in the ground film to make the ground film more stable after covering, reduce the chance of the ground film being lifted up, and improve the efficiency of rainwater entry.

[0028] Specifically, in one embodiment, regarding the above-mentioned feeding part:

[0029] like Figures 1-4 and Figure 6 As shown, the feeding part includes two symmetrically arranged top plates 32, a base plate 31 is arranged below the top plates 32, and the bottoms of the two top plates 32 are fixedly connected to the top of the base plate 31, the base plate 31 is fixedly connected between the two moving parts 2, the tops of the two top plates 32 are recessed to form a placement groove 33, a detachable raw material roller 34 is installed between the two placement grooves 33, the ends of the two raw material rollers 34 are screwed together with a detachable screw ring 35, and the connecting plate 313 is fixedly connected to the top of the base plate 31.

[0030] In this embodiment, when personnel need to cover the cultivated land with ground film, the material roller 34 with the ground film rolled up is placed in the placement groove 33 between the two top plates 32, and then the screw ring 35 is screwed and connected to the end of the material roller 34, and the screw ring 35 is against the top plate 32 to complete the installation of the material roller 34. When the device moves, the ground film is supplied through the material roller 34.

[0031] In addition, in the present invention, regarding how to install the laminating roller 310, as shown in FIG. Figures 1-4 andFigure 6 As shown, two chassis 39 are symmetrically and fixedly connected to the bottom of the substrate 31, and the film laminating roller 310 is rotatably connected between the two chassis 39.

[0032] In this embodiment, the chassis 39 are supported by the substrate 31, and the film laminating roller 310 is supported by the chassis 39, so that the film laminating roller 310 can rotate conveniently for film lamination.

[0033] When the device conveys the ground film, in order to make the conveyance of the ground film smoother, as Figure 6 shown, a side groove 37 is recessed on one side of the substrate 31 facing the film laminating roller 310. Two guiding rollers 38 are symmetrically and rotatably connected inside the side groove 37, and a guiding cavity for the ground film to pass through is formed between the two guiding rollers 38.

[0034] In this embodiment, when the ground film is covered, the two guiding rollers 38 are supported by the side groove 37 on one side of the substrate 31. After the ground film passes through the guiding cavity, the two guiding rollers 38 rotate, so that the ground film is covered more smoothly and the efficiency of ground film covering is improved.

[0035] Specifically, in one embodiment, regarding the above Figures 1-4 and Figure 6 shown, the moving member 2 includes two symmetrically arranged support plates 23. At least two rollers 22 are rotatably connected between the two support plates 23, and a crawler 21 is sleeved between the at least two rollers 22.

[0036] In this embodiment, when the towing member 1 drives the device to move, the rollers 22 are supported by the support plates 23. By the rotation of the rollers 22, the crawler 21 moves, so that the device moves and the ground film can be covered conveniently.

[0037] In addition, in this new type of use, regarding the above towing member 1, as Figures 1-3 and Figure 5 shown, the towing member 1 includes a conical frame 11.
