Description

Technical Field

[0001] This utility model relates to the technical field of agricultural film laying devices, and in particular to a convenient automatic laying device for biodegradable agricultural film. Background Technology

[0002] With the accelerated advancement of agricultural modernization, biodegradable agricultural films are being used more and more widely in agricultural production due to their environmental advantages. In the process of laying biodegradable agricultural films, automatic laying devices have greatly improved laying efficiency and reduced the burden of manpower.

[0003] Currently, most mainstream automatic laying devices on the market are too large, which not only results in poor equipment mobility, making it difficult to operate flexibly on narrow field ridges and irregularly shaped plots, but also leads to high transportation and storage costs and poor adaptability. In small-scale farmers' scattered and fragmented farmland, it is difficult to give full play to its advantages, resulting in resource waste. In view of this, we propose a convenient biodegradable agricultural film automatic laying device to improve the above-mentioned problems.

[0005] The main objective of this invention is to provide a convenient automatic biodegradable agricultural film laying device that can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A convenient automatic biodegradable agricultural film laying device includes a mounting frame. A hinge seat is fixedly installed at the top center of the horizontal direction of the mounting frame. A pull handle is glued to the inner surface of the hinge seat. Connecting components are symmetrically arranged at the middle of the opposite sides of the two ends of the mounting frame in the vertical direction. Travel linkage components are symmetrically installed on the lower front part of the mounting frame away from the two ends in the vertical direction. Two film pressing components are respectively arranged on the lower rear part of the mounting frame close to the two ends in the vertical direction.

[0008] Preferably, the connecting assembly includes two rotating rods and two clamping plates. The two rotating rods are symmetrically installed through the middle of both ends of the mounting frame in the height direction, and two stop rings are fixedly installed on the opposite surfaces of the two rotating rods respectively.

[0009] Preferably, the outer surfaces of the two rotating rods are respectively provided with a plurality of limiting grooves in a common annular array, and the middle portions of the two clamping plates are respectively provided with two sliding holes that slide with the outer surfaces of the two rotating rods, and two plastic spring pieces are respectively symmetrically installed on the opposite surfaces of the two clamping plates.

[0010] Preferably, two abutment rings are fixedly installed on the outer surfaces of the two limiting grooves away from the two plastic springs, and two springs are respectively sleeved on the outer surfaces of the two rotating rods. The two ends of the two springs abut against the opposite surfaces of the two abutment rings and the two clamping plates.

[0011] Preferably, the driving linkage component includes two fixed shafts and four gears. The two fixed shafts are symmetrically rotatably mounted on the front side of the lower part of the vertical ends of the mounting frame. The four gears are symmetrically sleeved on the outer surfaces of the two fixed shafts and the two rotating rods in pairs. A chain is connected between the two gears on the same side. Two driving wheels are fixedly mounted on the outer surfaces of the two fixed shafts respectively.

[0012] Preferably, the pressure film assembly includes two threaded rods, which are symmetrically fixedly installed on the rear side of the vertically opposite face of the mounting frame.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-5 As shown, a convenient biodegradable agricultural film automatic laying device includes a mounting frame 1. A hinge seat 2 is fixedly installed at the top center of the mounting frame 1 in the horizontal direction. A pull handle 3 is glued to the inner surface of the hinge seat 2. Connecting components 4 are symmetrically arranged at the middle of the opposite sides of the two ends of the mounting frame 1 in the vertical direction. Travel linkage components 6 are symmetrically installed at the lower front part of the mounting frame 1 at the two ends of the vertical direction. Two film pressing components 5 are respectively arranged at the lower rear part of the mounting frame 1 at the two ends of the vertical direction.

[0025] In actual use, the device clamps and positions film rolls of different widths through the connecting component 4. Pulling the hinge seat 2 at the top of the mounting frame 1 drives the device forward through the travel linkage component 6. During the forward sliding motion, the travel linkage component 6 drives the connecting component 4 to rotate together, laying the film roll on the connecting component 4 onto the ground. At the same time, the film pressing component 5 is set to rotate and press the laid film roll into the soil, preventing the laid agricultural film from being affected by the wind and causing problems such as displacement or overturning.

[0026] Specifically, the connecting component 4 includes two rotating rods 41 and two clamping plates 45. The two rotating rods 41 are symmetrically installed through the middle of both ends of the mounting frame 1 in the height direction. Two stop rings 47 are fixedly installed on the opposite surfaces of the two rotating rods 41 respectively.

[0027] The outer surfaces of the two rotating rods 41 are respectively provided with a plurality of limiting grooves 42 in a common annular array. The middle parts of the two clamping plates 45 are respectively provided with two sliding holes 451 that slide with the outer surfaces of the two rotating rods 41. Two plastic spring pieces 46 are respectively symmetrically installed on the opposite surfaces of the two clamping plates 45.

[0028] Two abutment rings 43 are fixedly installed on the outer surface of the two limiting grooves 42 away from the two plastic spring pieces 46 respectively. Two springs 44 are respectively sleeved on the outer surface of the two rotating rods 41. The two ends of the two springs 44 abut against the opposite surfaces of the two abutment rings 43 and the two clamping plates 45 respectively.

[0029] The film roll is inserted between the two rotating rods 41. The tension of the two springs 44 pushes the two clamping plates 45 to hold against the two ends of the film roll. In this way, the two clamping plates 45 can be adjusted according to the width of the film roll. In order to prevent the film roll from not rotating when the two rotating rods 41 are rotating, the two clamping plates 45 are respectively equipped with sliding holes 451 on their opposite surfaces. When the two clamping plates 45 hold against the two ends of the film roll, the sliding holes 451 can be inserted into the inner cavity of the film roll and tighten its inner cavity wall.

[0030] Furthermore, the driving linkage component 6 includes two fixed shafts 61 and four gears 62. The two fixed shafts 61 are symmetrically rotated and installed on the front side of the lower part of the vertical ends of the mounting frame 1. The four gears 62 are symmetrically sleeved on the outer surfaces of the two fixed shafts 61 and the two rotating rods 41. A chain 63 is connected between the two gears 62 on the same side. Two driving wheels 64 are fixedly installed on the outer surfaces of the two fixed shafts 61 respectively.

[0031] During the travel of the driving wheel 64, the two gears 62 on the same side and the chain 63 drive the rotating rod 41 on the same side to rotate, thereby causing the film on the rotating rod 41 to rotate together.

[0032] Furthermore, the pressure film assembly 5 includes two threaded rods 51, which are symmetrically fixedly installed on the rear side of the vertically opposite face of the mounting frame 1. Two stop rings 56 are fixedly installed on the opposite face of the two threaded rods 51, and two connecting rings 52 are slidably installed on the outer surface of the two threaded rods 51.

[0033] Two pressure rollers 53 are rotatably mounted on the outer surfaces of the two connecting rings 52 respectively. Two springs 54 are respectively sleeved on the outer surfaces of the two threaded rods 51. The two ends of the two springs 54 abut against the two connecting rings 52 and the two vertical end faces of the mounting bracket 1 respectively. Two threaded rings 55 are threadedly mounted on the outer surfaces of the two threaded rods 51 respectively. The two threaded rings 55 abut against the end faces of the two pressure rollers 53 away from the two springs 54 respectively.

[0034] The agricultural film laid on the ground is pressed down by two pressure rollers 53. As the pressure rollers 53 rotate and move, the agricultural film on the ground is pressed into the soil by the pressure rollers 53, thus avoiding the agricultural film from shifting or overturning due to wind after it is laid.

[0035] The tension of spring 54 pushes the connecting ring 52 to one side, and the screw ring 55 is turned to limit the offset pressure roller 53. In this way, the distance between the two pressure rollers 53 can be adjusted according to the width of the agricultural film.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
