Description

Technical Field

[0001] The utility model relates to the technical field of film covering machines, in particular to a farmland film covering device. Background Art

[0002] Farmland film covering refers to a measure of covering the ground surface with agricultural plastic films, which has the functions of reducing raindrop impact, preventing scouring and crust formation; it can effectively reduce the evaporation of soil moisture, conserve soil moisture during drought, raise soil moisture after rain, promote the absorption and growth of crops, and improve the utilization efficiency of soil moisture. Currently, the commonly used film covering machine in farmland is the hand-in-hand film covering machine.

[0003] When the existing hand-pulled film covering machine is in use, the film can be covered in the field. However, after the covering is completed, personnel need to use a spade or other auxiliary tools to cut it, resulting in inconvenience during film cutting. Therefore, we propose a farmland film covering device to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and propose a farmland film covering device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A farmland film covering device includes a film covering machine main body. The bottom end of the film covering machine main body is fixedly connected with a film covering installation head, and a film roll is installed above the film covering installation head. A moving mechanism is installed on the surface of the film covering machine main body, and a guiding mechanism is slidably connected inside the moving mechanism. A pushing mechanism is inserted inside the guiding mechanism, and a cutting mechanism is fixed at the end of the pushing mechanism.

[0007] Preferably, the moving mechanism includes mounting bolts. The surface of the film covering machine main body is provided with a mounting plate through the mounting bolts, and the end face of the mounting plate is fixedly connected with the side surface of a guiding slide rod. The guiding slide rod can be conveniently disassembled and installed by passing the mounting bolts through the mounting plate.

[0008] Preferably, the guiding mechanism includes a moving slider. The moving slider is slidably connected inside the guiding slide rod, and an outer end of the moving slider is fixedly connected with a guiding block. A guiding slider is fixedly connected to the inner wall of the guiding block. The position of the guiding block can be conveniently adjusted through the moving slider.

[0009] Preferably, the pushing mechanism includes a pushing column. The pushing column is inserted inside the guiding block, and one end of the pushing column is fixedly connected with a fixed disk. The surface diameter of the pushing column is smaller than the surface diameter of the fixed disk. By telescoping and moving the pushing column inside the guiding block, the function of controlling the cutting mechanism to cut the film roll can be facilitated.

[0010] Preferably, the pushing column is arranged in a cylindrical shape, a round hole adapted to the pushing column is formed inside the guiding block, and a sliding groove adapted to the guiding slider is formed on the surface of the pushing column. By arranging the pushing column in a cylindrical shape, the friction force between the pushing column and the guiding block can be reduced.

[0011] Preferably, a return spring is sleeved on the surface of the pushing column, and a return spring is welded between the guiding block and the fixed disk. The pushing column can drive the cutting mechanism to reset and retract through the return spring.

[0012] Preferably, the cutting mechanism includes a plug-in frame. The end of the pushing column is fixedly connected with the plug-in frame, and a cutting tool head is inserted inside the plug-in frame. An extrusion bolt is threadedly inserted on the surface of the plug-in frame, and the surface of the extrusion bolt abuts against the surface of the cutting tool head. By installing the cutting tool head in a plug-in manner with the plug-in frame, the cutting tool head can be conveniently replaced.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By pulling the pushing column, the guiding block can drive the moving slider to slide left and right along the inside of the guiding rod, which is convenient for adjusting the position of the cutting mechanism. By pressing the fixed disk, the pushing column can telescopically move along the inside of the guiding block, which is convenient for the cutting mechanism to cut the film roll, improving the film covering efficiency of the film roll. At the same time, through the elastic force of the return spring itself, the film roll can be conveniently reset and retracted during the film covering process.

[0015] 2. By passing the mounting bolt through the mounting plate and threadedly connecting it with the film covering device main body, the guiding rod can be conveniently disassembled and installed, facilitating the disassembly and replacement of the guiding mechanism and the pushing mechanism when they are damaged. At the same time, by taking out the extrusion bolt from the inside of the plug-in frame, the cutting tool head can be conveniently disassembled and replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Furthermore, referring to Figure 1 and Figure 3 , it can be known that the moving mechanism 4 includes a mounting bolt 41. A mounting plate 42 is installed on the surface of the film mulching device main body 1 through the mounting bolt 41, and the end face of the mounting plate 42 is fixedly connected to the side surface of the guide slide bar 43. By screwing the mounting bolt 41 through the mounting plate 42 and the film mulching device main body 1, the function of installing the guide slide bar 43 can be facilitated.

[0028] Furthermore, referring to Figure 3 and Figure 4 , it can be known that the guiding mechanism 5 includes a moving slider 51. The moving slider 51 is slidably connected inside the guide slide bar 43, and the outer end of the moving slider 51 is fixedly connected to a guide block 52.

By the sliding connection of the moving slider 51 and the guide slide bar 43, the position of the cutting mechanism 7 can be conveniently adjusted.

[0029] Furthermore, referring to Figure 3 and Figure 4It can be known that the pushing mechanism 6 includes a pushing column 61. The pushing column 61 is inserted inside the guiding block 52, and one end of the pushing column 61 is fixedly connected to a fixing plate 62. The surface diameter of the pushing column 61 is smaller than the surface diameter of the fixing plate 62. The fixing plate 62 can facilitate the function of limiting the pushing column 61.

[0030] Furthermore, referring to Figure 4 It can be known that the pushing column 61 is set to be cylindrical. A round hole adapted to the pushing column 61 is opened inside the guiding block 52. Through the round hole opened inside the guiding block 52, the pushing column 61 can move in the round hole. A sliding groove adapted to the guiding slider 53 is opened on the surface of the pushing column 61. Through the sliding groove opened on the surface of the pushing column 61, the guiding slider 53 can slide along the sliding groove, playing a role in guiding the pushing column 61.

[0031] Furthermore, referring to Figure 3 and Figure 4 It can be known that a return spring 63 is sleeved on the surface of the pushing column 61.
