Description

Technical Field

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

[0002] Film mulching of crops has become an important measure to increase agricultural production in the world. Film mulching can effectively keep warm and inhibit the growth of weeds, which is also conducive to reducing humidity and the occurrence of pests and diseases.

[0003] However, in the process of planting, the width and height of the raised land after trenching or the land after reclamation are uncertain, which leads to the inability of traditional film covering machines to lay the film well. The film covering position cannot be adjusted. When the trench is too deep, the film covering wheel is easy to collide with the soil. When the film covering is not completed, it will be damaged due to wear and tear with the soil, which is not conducive to the laying of the planting film. Therefore, a film covering device for planting is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology.

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

[0007] Preferably, two guide posts are provided, and the two guide posts pass through the inside of the side rod through a through hole. The guide posts can be guided by the through hole of the side rod to ensure that the guide posts move up and down in the through hole of the side rod.

[0008] Preferably, the clamping shaft consists of a side plate end and an insertion shaft end, and rubber rings are equidistantly arranged on the outside of the insertion shaft end of the clamping shaft. The insertion shaft end of the clamping shaft is inserted on both sides of the coating roller, which can facilitate clamping and fixing of the coating roller.

[0009] Preferably, two push rods are symmetrically installed on the outer side of one of the side rods on the right side, and a soil turning assembly is installed on the outer side of one of the side rods on the right side near the push rod. The design of the push rod can facilitate the staff to hold and push the push rod, thereby ensuring the convenience of manual operation of the push rod.

[0010] Preferably, the soil turning assembly includes an extension rod, the bottom end of which is connected to a support rod, and a soil turning plate is installed at the bottom end of the support rod. The inclined soil turning plate is designed to turn the soil on the side of the groove while the soil turning plate is moving.

[0011] Preferably, a pressing assembly is installed at the center of the bottom end of the connecting frame, and the pressing assembly includes an inner shaft, and a pressing roller is installed at the bottom end of the inner shaft.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. By setting up the laminating component, the adaptive adjustment of the laminating position is realized. Compared with the traditional structure, the device can push the beam rod downward by moving the threaded shaft in the threaded hole of the side rod. The beam rod can change the position of the two guide columns during movement, so that the guide column can push the clamping shaft to move, thereby changing the height of the laminating roller clamped between the two clamping shafts, which is convenient for laminating operations on different terrains. At the same time, the threaded shaft moves in the threaded hole on the side of the bottom end of the guide column, and then pushes the clamping shaft to move, which is convenient for the installation of laminating rollers of different lengths.

[0015] 2. By setting up a downward pressure component, the downward pressure and auxiliary support of the film body can be achieved. This device pushes the inner shaft through the rebound force of the inner shaft, so that the inner shaft can move inside the shaft tube. After the inner shaft moves, the downward pressure roller can be used to press down. The downward pressure roller assists the newly laid film body to ensure stability during laying and reduce the chance of film folding during lamination. BRIEF DESCRIPTION OF THE DRAWINGS
