DETAILED DESCRIPTION
[0015] The utility model will be further described below in conjunction with the accompanying drawings.
[0016] like Figures 1 to 3 The film laying machine with automatic film cutting function shown in the figure comprises a frame 1 and a hanging frame 2. U-shaped fixing frames 18 are welded at both ends of the frame 1. The hanging frame 2 is vertically welded to the middle of the frame 1. In order to install the automatic film cutting device, a cross bar 3 is welded at the upper end of the hanging frame 2. A mounting frame 4 is welded at the other end of the cross bar 3. A support plate 5 is welded on the mounting frame 4. A hydraulic cylinder 8 is rotatably connected to the support plate 5. The output end of the hydraulic cylinder 8 is rotatably connected to a first connecting plate 10. The other end of the first connecting plate 10 is rotatably connected to a second connecting plate 10. The second connecting plate 11 is welded to the back of the film cutting plate 12. The film cutting plate 12 is designed to be a round tube on the top, and a bent plate is welded at the bottom. A pair of support plates are welded in the middle of the bent tube, and the film cutting plate 12 can be rotatably connected to the bottom end of the mounting frame 4. In order to prevent the first connecting plate 10 and the second connecting plate 11 from interlocking during the rotation process and facilitate the movement of the film cutting plate 12, a U-shaped bent plate 9 is rotatably connected at the connection between the mounting frame 4 and the film cutting plate 12, and the other end of the U-shaped bent plate 9 is rotatably connected to the output end of the hydraulic cylinder 8. In order to enable the soil covering roller 13 to be lifted and lowered at the beginning and end of film laying, a T-shaped frame 23 is fixedly connected at the connection between the frame 1 and the suspension frame 2, and both ends of the T-shaped frame 23 are fixedly connected to the U-shaped fixing frame 18. In order to enable the soil covering roller 13 to be adjusted autonomously according to the height of the terrain during film laying, a first bracket 17 is rotatably connected to the T-shaped frame 23 through a sleeve. For the convenience of maintenance, the second bracket 14 is fixedly connected to the other end of the first bracket 17 through bolts. One end of the second bracket 14 is rotatably connected to the first bracket 17. It is dynamically connected to a soil covering roller 13, and is fixedly connected to a support base 20 on a U-shaped fixed frame 18. A film transport roller 21 is detachably connected to the support base 20, so that the ground film can be replaced at any time. In order to install the device on an agricultural four-wheel vehicle, a traction frame 22 is fixedly connected to the suspension frame 2, and an opening is provided at the front end of the traction frame 22 for easy installation and disassembly. At the same time, two through holes are relatively opened at the front end of the U-shaped fixed frame 18 for easy installation on the four-wheel vehicle, and the lifting and lowering of the film laying machine are realized by the hydraulic device of the four-wheel vehicle.
[0017] In order to improve the degree of automation of the device and realize automatic film cutting of the film cutting device, a first oil inlet pipe 6 is fixedly connected to one end of the hydraulic cylinder 8 and a second oil inlet pipe 7 is fixedly connected to the other end. When film cutting is required, the valve of the first oil inlet pipe 6 is opened, and the output end of the hydraulic cylinder 8 begins to extend, thereby driving the film cutting plate 12 downward to cut the film. When film laying needs to be restarted, the valve of the second oil inlet pipe 7 is opened, and the output end of the hydraulic cylinder 8 is recovered, driving the film cutting plate 12 to be lifted upward.
[0018] In order to improve the quality and efficiency of film laying and realize automatic soil covering, a ditching disc 16 and a soil-moving disc 15 are rotatably connected to the U-shaped fixed frame 18 through an iron rod. The soil-moving disc 15 is set to be in an inner-toe shape to move the soil into the soil-covering roller 13 during walking.
[0019] In order to maintain the stretch of the ground film and prevent it from being twisted into other parts, a film spreading roller 19 is rotatably connected to the U-shaped fixing frame 18.
[0020] It should be noted that in the present invention, the interior of the soil covering roller 13 is arranged in a spiral shape, and holes are provided on the surface of the soil covering roller 13. The soil inside the soil covering roller 13 can flow out through the holes during rotation and cover the ground film, so that the soil covering effect is better.
[0021] The specific working process of the utility model is as follows:
[0022] When it is necessary to lay the film, first install the device behind the four-wheel vehicle through the through hole opened in the front end of the traction frame 22 and the U-shaped fixing frame 18, and at the same time install the ground film roll on the grinding roller 21, flatten the ground film and pass it under the film spreading roller 19, and pull the ground film to the rear of the covering roller 13. At this time, the hydraulic cylinder 8 is in a recovery state, and the film cutting plate 12 is lifted, and the soil is covered on the head end of the ground film. The four-wheel vehicle is operated to lower the device until it is completely in contact with the ground and then slowly drives forward. At this time, under the action of tension, the ground film on the grinding roller 21 begins to rotate, and the ditching disc 16 digs a ditch in the front. The ground film is flatly laid on the ground under the pressure of the covering roller, and at the same time, the soil-digging disc 15 lifts the soil on the ground during the movement and covers the edge of the film. At the same time, the excess soil is pushed into the covering roller 13 and rotated. At the same time, the oil flows out through the holes on the covering roller 13 and covers the ground film. When a row of film is laid, the valve of the first oil inlet pipe 6 is opened, and the output end of the hydraulic cylinder 8 extends, thereby pushing the film cutting plate 12 downward, cutting the ground film and digging up a piece of soil at the same time, close to the surface of the covering roller 13. At this time, the device is lifted up, and when the device changes lines to lay the film again, the device is lowered and the valve of the second oil inlet pipe 7 is opened. At this time, the output end of the hydraulic cylinder 8 begins to shrink, driving the film cutting plate 12 to turn outward, pushing away the soil on the ground and burying the ground film, realizing the automatic covering process, and the device moves forward and continues to repeat the previous actions to lay the film. Laying the film according to the above steps can realize the process of automatic covering and film cutting of the device, improve the working efficiency of film laying, and reduce the intensity of manual labor.
