Description

Technical Field

[0001] The utility model relates to agricultural machinery and equipment, in particular to a film covering machine for laying ground film. Background Art

[0002] Film mulching cultivation is to cover the ground with a transparent plastic film, sow seeds under the film and protect the growth of crop seedlings; when the temperature warms up, the film is uncovered to allow the seedlings to grow under normal climatic conditions. With the popularization of agricultural machinery and equipment, mulch film laying is usually mechanized. The existing film covering mechanism is usually attached to agricultural machinery (such as tractors), and the agricultural machinery carries the film covering mechanism to complete the mulch film laying in the farmland. This film laying method makes it difficult for the driver to observe the mulch film laying situation, and the operator needs to look back frequently to observe whether the mulch film laying is intact. There is also a special film laying equipment, which uses a hand tractor to pull the film covering mechanism to lay the mulch film. The operator and the film covering mechanism are on the same side. If you want to observe the mulch film laying situation easily, you need to step on the film, which is easy to cause the film to break, or stand on the film covering mechanism to operate the hand tractor, and you still need to look back to observe the film laying situation, which affects the operation. In addition, traditional hand tractors are difficult to turn, which increases the difficulty of operation. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, a film covering machine is provided which is convenient for turning and can observe the laying of ground film in real time. The technical solution adopted by the utility model is:

[0004] The film covering machine comprises a film covering mechanism that carries the film and can cover the film on the farmland, a traction mechanism that pulls the film covering mechanism to walk in the farmland,

[0005] The traction mechanism comprises a frame, an engine arranged on the frame and a pair of power wheels, and a handrail is also arranged on the frame;

[0006] The output end of the engine is provided with a reduction box, and each of the power wheels is connected to the output end of the reduction box through a pair of clutches;

[0007] A pair of handles are provided on the armrests to respectively control the clutch engagement state;

[0008] The handrail is arranged at the front end of the frame in the direction of travel, and the laminating mechanism is arranged at the rear end of the frame in the direction of travel.

[0009] Furthermore, the film covering mechanism includes a traction frame connected to the frame, on which a reeling roller for mounting a ground film roll and a pressing roller for pressing the ground film onto the ground are provided, and along the traveling direction, a pair of turning plates capable of pushing the soil on both sides of the ground film outwards are provided at the front end of the pressing roller on the traction frame, and along the traveling direction, a pair of pressing wheels for compacting the edges of the ground film and a pair of covering wheels for bringing the soil on both sides of the ground film closer to the center and covering the edges of the ground film are provided at the rear end of the pressing roller on the traction frame.

[0010] Furthermore, the heights of the tilling plate, unwinding roller, pressure roller and covering wheel are adjustable; the spacing between the tilling plate, pressure wheel and covering wheel is adjustable; and the pressure wheel can be turned over and lifted.

[0011] Furthermore, the positions of the unwinding roller, the pressure roller and the tiller plate along the traveling direction can be adjusted.

[0012] In the laminating machine with the above structure, since the handrail is located in front of the laminating mechanism, the personnel can always observe the film laying situation when walking backwards during driving, and the rotation of each power wheel is controlled by the clutch, so there is no need to move the handrail to turn, which is convenient and labor-saving to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the structure of the laminating machine. DETAILED DESCRIPTION

[0014] The technical solution of the utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1 The film covering machine shown includes a film covering mechanism and a traction mechanism, wherein the film covering mechanism is towed by the traction mechanism to move in the farmland. When moving, the ground film roll carried by the film covering mechanism is laid on the path traveled by the film covering mechanism and the edge of the film is covered with soil to complete the laying of the ground film.

[0016] The above-mentioned traction mechanism includes a frame 1, on which an engine 2 and an armrest 5 are arranged, a reduction box 4 is arranged at the output end of the engine 2, and a pair of power wheels 3 are also arranged on the frame 1. The power wheel 3 is connected to the reduction box 4 through a clutch (located in the reduction box and not released in the figure), and each power wheel 3 is equipped with a clutch connected to the reduction box 4. A pair of handles 6 are arranged on the armrest 5 to control the clutch state of each clutch, and the clutch state of the clutch can control the power on and off of the power wheel 3 matched with it. When the clutch matched with it is in a disengaged state through one side of the handle, the power of the power wheel 3 on this side is cut off, while the power wheel 3 on the other side operates normally. At this time, turning can be achieved (that is, turning towards the side where the power is cut off). Specifically, in this embodiment, the brake line 14 connected to the handle 6 drives the clutch to separate.

[0017] In order to be able to observe the laying of the ground film by the coating mechanism in real time, along the traveling direction, the above-mentioned handrail 5 is arranged at the front end of the frame 1, and the coating mechanism is arranged at the rear end of the frame 1. When working, the operator holds the handrail 5 with both hands and walks backwards. By controlling the direction through the handle 6, the operator can observe the laying of the ground film by the coating mechanism in real time and make timely adjustments to the laying of the ground film.

[0018] The above-mentioned film covering mechanism includes a traction frame 8 connected to the frame 1, and a reel 9 is provided on the traction frame 8 for installing the ground film roll. A pressure roller 10 is also provided on the traction frame 8 below the reel 9. After the film is drawn out from the reel 9, it is arranged under the pressure roller 10, and the ground film is pressed tightly on the ground by the pressure roller 10. In this way, when the film covering mechanism is moving, the ground film will be continuously drawn out and laid on the travel route. In addition to laying the ground film on the ground, the edge of the ground film needs to be covered with soil. Therefore, a pressure roller 10 is also provided on the traction frame 8. A pair of pressing wheels 12 are provided to compact the edges of the ground film on both sides to make them fit the ground, and a pair of covering wheels 13 are also provided on the traction frame 8 to cover the soil at the edges of the film on both sides to keep the film on the ground. Since the pressing and covering of the film are carried out after the film is laid on the ground, the pressing wheels 12 and the covering wheels 13 are both behind the unwinding roller 9 and the pressing roller 10 in the direction of travel. Moreover, since pressing is required before covering with soil, the covering wheels 13 are slightly behind the pressing wheels 12 in the direction of travel. In order to provide enough soil for the covering wheel 13 to cover the edge of the film and ensure that the edge of the film is slightly lower than the surface of the film, a pair of overturning plates 11 are also arranged on the traction frame 8. The pair of overturning plates 11 are arranged to the front end of the unwinding roller 9 and the pressing roller 10 along the traveling direction. When moving, the overturning plates 11 turn the soil outward to form a ditch, and the edge of the ground film is compacted in the ditch by the pressing wheel 12, and the covering wheel 13 covers the soil turned over by the overturning plates 11 to the edge of the ground film again, thereby ensuring that the film is firmly held in the ground to complete the covering operation.

[0019] In order to meet the requirements of coating operations for different film widths and coating heights, the height of the above-mentioned tillage plate 11, unwinding roller 9, pressure roller 10 and covering wheel 13 can be adjusted; the spacing between the tillage plate 11, pressure wheel 12 and covering wheel 13 can be adjusted, and in this embodiment they are all assembled and installed in the form of sleeves for adjustment.

[0020] Since the edge pressing wheel 12 is always in contact with the ground, in order to avoid affecting walking when the film is not laid, the edge pressing wheel 12 can be flipped and lifted. After being lifted, the edge pressing wheel 12 is away from the ground to avoid contact with the ground.

[0021] The positions of the unwinding roller 9 and the pressing roller 10 can be adjusted in the traveling direction, so that the film is in a reasonable position when laid in the farmland, that is, the soil turning, edge pressing and soil covering are in reasonable positions without affecting each other and the edge of the film can be covered in place.
