Description

Technical Field

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

[0002] Agricultural planting is a mode of production. Specifically, it is through artificial cultivation, including the cultivation of various crops, trees, fruit trees, flowers, medicinal and ornamental plants, that crops can convert carbon dioxide and water in the environment into carbohydrates under sunlight by relying on their natural growth physiological functions. In agricultural planting, in order to avoid large-scale death of some crops due to temperature differences, crops are usually covered with films to keep them warm and moist. When using some simple film covering devices to cover areas that are not convenient for large-scale equipment to enter, the rolled transparent plastic film is usually limited on the film covering device, and then the film covering operation can be achieved by pulling the film covering device. Since some existing film covering devices need to be manually cut with scissors or other tools to cut the film after completing a film covering, the film covering operation is not convenient enough, which reduces the film covering efficiency to a certain extent. Therefore, an agricultural planting film covering device is proposed to address the above problems. Utility Model Content

[0003] The technical problem to be solved by the utility model overcomes the existing defects and can effectively solve the problems in the background technology.

[0011] 1. An agricultural planting film covering device, which is provided with a handle, a piston plate, a piston box, an air pipe, a sleeve shaft, an inner shaft, a clamping rod, a spring, a resistance wire and a control switch. When a film covering operation is completed through the device, the piston rod is pulled by the handle to further pull the piston plate and the piston cylinder to slide, and the gas in the piston cylinder can be pressed into the sleeve shaft through the air pipe.

In this process, the clamping rod will also push the plastic film to contact the resistance wire. When the handle triggers the control switch to start the resistance wire, the started resistance wire will heat and cut off the plastic film. After completing a film covering operation, the clamping rod is controlled to push the plastic film to be heated and cut off by the started resistance wire, so that the film covering operation is more convenient, thereby greatly improving the efficiency of film covering.

[0024] Example 2

[0025] like Figure 1-3 As shown, in order to solve the problem of inconvenience in limiting the rolled transparent plastic film on the device, the bottom end of the inner side of the bracket 1 is rotatably connected with a threaded shaft 3 that penetrates the bracket 1, and the outer side of the threaded shaft 3 is spirally connected with a clamping block 4 that is slidably connected to the bracket 1, and the outer side of the clamping block 4 is fixedly connected with a limiting shaft 5. By placing the rolled transparent plastic film between the two clamping blocks 4 and then rotating the threaded shaft 3 to be spirally connected with the clamping block 4, the clamping block 4 further drives the limiting shaft 5 to be inserted into the rolled transparent plastic film reel, which facilitates limiting the rolled transparent plastic film on the device.

[0026] Example 3

[0027] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in order to solve the problem that it is inconvenient to control the clamping rod 10 to push the transparent plastic film to contact the resistance wire 7, the top end of the sleeve shaft 8 is connected to an air pipe 12, and the top end of the air pipe 12 is connected to a piston cylinder 13, and the piston cylinder 13 is fixedly connected to the bracket 1, and the inner side of the piston cylinder 13 is slidably connected to a piston plate 14, and the top end of the piston plate 14 is fixedly connected to a piston rod 15 that penetrates the piston cylinder 13, and the piston rod 15 is slidably connected to the piston cylinder 13, and the top end of the piston rod 15 is fixedly connected to a handle 16 that is slidably connected to the bracket 1, and the piston rod 15 is pulled by the handle 16, and the piston plate 14 is further pulled to slide with the piston cylinder 13, so that the gas in the piston cylinder 13 is pressed into the sleeve shaft 8 through the air pipe 12, which facilitates the contact of the plastic film with the resistance wire 7 through the clamping rod 10.

[0028] Example 4

[0029] like Figure 3 As shown, in order to solve the problem of inconvenience in controlling the start of the resistance wire 7, a control switch 17 is provided on the top of the handle 16, and the control switch 17 is fixedly connected to the bracket 1. The control switch 17 is triggered by pulling the handle 16, which facilitates the start of the control resistance wire 7.

[0030] Example 5

[0031] like Figure 3-4 As shown, in order to solve the problem of inconvenience in replacing the broken resistance wire 7, the end of the resistance wire 7 is fixedly connected with a connecting block 18, and the connecting block 18 is slidably connected to the fixing frame 6, and the left and right sides of the bottom end of the fixing frame 6 are spirally connected with bolts 19, and the bolts 19 are spirally connected to the connecting block 18.

[0032] In this embodiment, when using the device for laminating, the rolled transparent plastic film is placed between the two clamping blocks 4, and then the threaded shaft 3 is rotated to be spirally connected with the clamping block 4, so that the clamping block 4 further drives the limiting shaft 5 to be inserted into the rolled transparent plastic film reel. After completing the above operations, the plastic film is passed between the clamping rod 10 and the fixing frame 6, and then the bracket 1 is pulled to perform the laminating operation. When a laminating operation is completed during the laminating operation by the device, the piston rod 15 is pulled by the handle 16, and the piston plate 14 and the piston cylinder 13 are further pulled to slide, and the gas in the piston cylinder 13 can be pressed into the sleeve shaft 8 through the air pipe 12, and then as the air pressure in the sleeve shaft 8 continues to increase, the inner shaft 9 will push the clamping rod 10 to move the inner shaft 9 ... The rod 10 compresses the spring 11. During this process, the clamping rod 10 will also push the plastic film to contact the resistance wire 7. When the handle 16 triggers the control switch 17 to start the resistance wire 7, the started resistance wire 7 will heat and cut the plastic film. By automatically cutting off the plastic film, the coating efficiency is greatly improved. During the use of the device, when the resistance wire 7 is broken or damaged due to long-term use, the connecting block 18 connected to the fixing frame 6 and the end of the resistance wire 7 is disconnected from the spiral connection by rotating the bolt 19. After the connecting block 18 is disconnected from the fixing frame 6 and the broken and damaged resistance wire 7 is removed, the resistance wire 7 can be replaced, thereby ensuring the normal cutting of the plastic film.
