Problems solved by technology

[0003] When building a greenhouse, it is enough to build the iron rod support first, and then spread the plastic film on it. However, the existing method is more troublesome when laying the film. When filming, spread the plastic film on the top of the greenhouse support, and then pull it from one side of the support to the other side, so that the plastic film is dragged on the support, so that the plastic film is laid
[0004] On the one hand, this method is labor-intensive, and the efficiency is very low. On the other hand, the plastic film is easily scratched by the nodes or protrusions of the bracket during the dragging process, which is not convenient enough.

Embodiment 1

[0026] see Figure 1-4 , a film laying device for agricultural greenhouses, including a fixed base, a telescopic and rotatable swing arm and a clamping piece, the base is movably connected to the swing arm and the base is provided with a drive mechanism, the drive mechanism and the swing The arm is connected by transmission and the end of the swing arm away from the base is provided with a clamping part. The base is provided with a fixing part and a buffer mechanism. When in use, first adjust the length of the swing arm to make it longer than the radius of the greenhouse. The plastic film of the greenhouse is Roll by roll, clamp a roll of plastic film with a clamping piece, pull out the plastic film and fix it with a fixing piece, start the driving mechanism, drive the swing arm to rotate, and make the plastic film roll pass along the outer surface of the greenhouse, During this period, the plastic film roll is rotating, and the plastic film is continuously pulled out and spre...

Embodiment 2

[0035] see Figure 5 , The difference between this embodiment and Embodiment 1 is that different drive mechanisms are used, the drive mechanism includes a drive shaft 5, a drive motor 22 and a drive wheel 8, and the drive motor 22 is fixedly connected to the drive shaft 5 and The end of the drive shaft 5 away from the drive motor 22 runs through the support base 3 and is movably connected with the support base 3 .

[0036] The working principle of the present invention is: when in use, first adjust the length of the swing arm so that its length is greater than the radius of the greenhouse. The plastic film of the greenhouse is rolled one by one, and a roll of plastic film is clamped by a clamping piece, and pulled The plastic film is fixed with a fixing piece, and the driving mechanism is started to drive the swing arm to rotate, so that the plastic film roll passes along the outer surface of the greenhouse. During this period, the plastic film roll is rotating, and the plasti...

Abstract

The invention discloses a film laying device for an agricultural greenhouse. The film laying device comprises a fixable base, a telescopic and rotatable swing arm and a clamping piece, the base is movably connected with the swing arm and provided with a driving mechanism, the driving mechanism is in transmission connection with the swing arm, and the clamping piece is arranged at the end, away from the base, of the swing arm; and the base is provided with a fixing piece and a buffer mechanism. According to the film laying device for the agricultural greenhouse, through cooperation of the fixable base, the telescopic and rotatable swing arm and the clamping piece, film laying is convenient, time and labor are saved, and needed manpower and material resources are reduced; and a plastic filmis directly laid on the surface of the greenhouse, pulling is not needed, and the plastic film cannot be scratched, so that the problems that in an existing manner, film laying is troublesome, the plastic film needs to be cut off from a plastic film roll firstly, consequently, on one hand, labor is consumed, efficiency is very low, on the other hand, the plastic film is prone to being scratched byjoints or protrusions of a support in the dragging process, and inconvenience is caused are solved.

Description

technical field [0001] The invention relates to a greenhouse construction device, in particular to a film laying device for an agricultural greenhouse. Background technique [0002] With the production of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan and European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. , my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used in small sheds to cover vegetables in Beijing, and achieved the effect of early maturity and increased production. Greenhouses were originally special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. [0003] When building a greenhouse, it is enough to build the iron rod support first, and then spread...
