Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering technology, and in particular to an agricultural thick film laying device. Background Technology

[0002] Laying devices refer to a general term for machinery used to accurately and efficiently place and install specific materials, components, and equipment into a target area according to preset position, angle, and path requirements. Through automation, semi-automation, and mechanization, they replace manual labor in laying operations that are highly repetitive, labor-intensive, and require high precision. They are widely used in construction, transportation, energy, communications, and water conservancy.

[0003] A thick film laying device for agriculture is specifically designed for agricultural production scenarios. It is used to unfold, position, and bury thick plastic films according to preset paths, depths, and tensions through the coordination of mechanical structures and control systems. It is suitable for agricultural films with high requirements for heat preservation, moisture retention, weed control, and aging resistance in agricultural production. Traditional thick film laying devices rely on manual operation and have a low degree of automation. Existing technologies have solved this problem by using machines to lay the films with traction frames. However, the film laying mechanism in the thick film laying device has a fixed height, resulting in poor adaptability to terrain undulations. Uneven farmland and inconsistent ridge heights cause the film to fail to adhere to the ground surface, resulting in wrinkles and gaps, thus losing the heat preservation and moisture retention effects. In addition, the film covering device can only cover a single layer of film, resulting in poor heat preservation and weak weed and insect control capabilities. Utility Model Content

When the operator pulls or pushes the handle 2071, the spring 2072 will deform. After the operation is completed, the handle 2071 can be reset by its own elasticity.

[0035] Meanwhile, multiple springs 2073 are fixedly connected to the left side of the outer wall of the movable frame 201. When the slide 202 slides, in actual operation, when it is necessary to adjust the film covering height according to the terrain, the operator pulls the handle 2071 to drive the push plate 206 to move.

The buckle plate 3064 can change position with the rotation of the rotating shaft 3063 and plays a role in positioning during the operation of the mechanism, ensuring the stable operation of the entire rotating assembly 306.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The flattening mechanism 4 includes a pressure roller 401, which is rotatably connected to the rear side of the outer wall of the frame 1. Multiple saw teeth 402 are fixedly connected to the rear side of the middle part of the pressure roller 401.

A support frame 9 is fixedly connected to both the left and right sides of the outer wall of the motor 4031.

[0040] Specifically, the pressure roller 401 of the flattening mechanism 4 is one of the main components, which is rotatably connected to the rear side of the outer wall of the frame 1. Multiple saw teeth 402 are evenly fixedly connected to the rear side of the middle part of the pressure roller 401. A flattening assembly 403 is rotatably connected to the left side of the outer wall of the pressure roller 401. The flattening assembly 403 includes a motor 4031, which is located on the left side of the outer wall of the pressure roller 401. The output end of the motor 4031 is fixedly connected to a roller 4032. When the motor 4031 starts, it will drive the roller 4032 to rotate synchronously.

[0041] On the left and right sides of the outer wall of the frame 1, there are fixed connecting plates 7, and screws 8 are threaded in the middle of the inner wall of the connecting plates 7. At the same time, support frames 9 are also fixedly connected on the left and right sides of the outer wall of the motor 4031, and screws 10 are threaded in the middle of the inner wall of the support frames 9. This effectively reduces the impact of the vibration generated by the motor 4031 during operation on the entire flattening mechanism 4 and ensures the efficiency of the flattening work.

[0042] Working principle: An agricultural thick film laying device includes a drive source adjustment component 207. The adjustment component 207 has a handle 2071, with a spring 2072 and a spring 2073 connected to its inner side. The handle 2071 is located inside a moving frame 201. A slide 202 is located in the middle of the moving frame 201, and a slot 203 is provided on the slide 202. A push plate 206 is mounted on the spring 2072, and one side is also provided with anti-slip texture. Adjustment is required. At the height, the operator can manually press the handle 2071. Then, the handle 2071 pops out from the slot 203 under the elastic action of spring 1 2072 and spring 2 2073 and the rotation of the connecting shafts 204 on both sides. The sliding column 205 assists the push plate 206 to separate from the slot 203 under the action of spring 2 2073. The outer walls of the moving frame 201 and the slide 202 are respectively fixed with mounting shafts 5, which can realize double-layer film coating, and the double-layer film can be selected with different materials and functions.

[0043] In an agricultural thick film laying device, the rotating component 306 in the adjusting mechanism 2 serves as the driving source. A rotating frame 302 rotates on the top of the fixed rod 301, and a fixed plate 303 rotates on the top of the rotating frame 302. The fixed rod 301 is installed inside the connecting frame 304, and a spring is fixed at the bottom of the fixed rod 301. When the pressure plate 3061 in the rotating component 306 is manually squeezed, the pressure plate 3061 rotates under the elastic action of the spring 3062 and the rotating shaft 3063, causing the buckle plate 3064 to separate from the rotating frame 302. At this time, rotating the rotating frame 302 changes its position. The rotating frame 302 directly drives the fixed rod 301 and the spring 305 to rotate. The angle of the soil wheel 6 at the bottom of the spring 305 can be adjusted according to actual needs. The spring 305 can also absorb vibration energy during the movement.
