Problems solved by technology

[0005] In order to overcome the need to continuously pull the opening tool to open the greenhouse film, it is laborious, the work efficiency is low, and the circular greenhouse film that appears after the opening needs to be removed, which is relatively troublesome. The technical problem of the present invention is: Provided is a ventilating device for greenhouses, which is convenient for people to open holes in the greenhouse film, saves labor, has high work efficiency, and does not require people to remove the circular greenhouse film.

Embodiment 1

[0024] An opening device for greenhouse ventilation, such as Figure 1-6 As shown, it includes a hollow rod 1, a partition frame 2, a first set of rods 3, an L-shaped tie rod 4, a first spring 5, a hole assembly 6 and a hook film assembly 7, and the left part of the hollow rod 1 is slidable. Frame 2, the first set of rods 3 with sliding type in the hollow rod 1, the sliding type in the first set of rods 3 is provided with an L-shaped tie rod 4, and the left end of the L-shaped tie rod 4 is connected with the left side of the first set of rods 3 There is a first spring 5, a hole assembly 6 is provided between the first set of rods 3, the hollow rod 1 and the partition frame 2, and a hook membrane module 7 is provided between the right part of the hollow rod 1 and the partition frame 2, and the hook membrane module 7 Cooperate with the hole assembly 6.

[0025] The hole opening assembly 6 includes a special-shaped slider 601, a second spring 602, a guide slider 603, a connectin...

Embodiment 2

[0031] On the basis of Example 1, as figure 1 , image 3 , Figure 4 and Figure 5 As shown, it also includes a push rod 8, a second set of rods 9 and a fifth spring 10, the left end of the L-shaped pull rod 4 is fixedly connected with a second set of rods 9, and the left end of the second set of rods 9 penetrates the middle of the left side of the first set of rods 3 The second set of rods 9 is slidably provided with a push rod 8 , and a fifth spring 10 is connected between the right end of the push rod 8 and the inner right side of the second set of rods 9 .

[0032] When the operator pulls the L-shaped rod 4 to move to the right, the L-shaped rod 4 also drives the second set of rods 9 to move to the right, and the second set of rods 9 moves to the right to drive the push rod 8 to move to the right, and the push rod 8 moves to the right When in contact with the hollow rod 1, the push rod 8 stops moving, the L-shaped pull rod 4 continues to drive the second set of rods 9 t...

Abstract

The invention relates to a hole opening device, in particular to a hole opening device for greenhouse ventilation. The technical problem is how to design a hole-opening device for greenhouse ventilation that can facilitate people to perforate the greenhouse film, is labor-saving, has high work efficiency, and does not require people to remove the circular greenhouse film. A hole-opening device for greenhouse ventilation, comprising: a hollow rod, and a partition frame is arranged in a circumferential sliding manner on the left part of the hollow rod; a first set of rods, the first set of rods is slidably placed in the hollow rod inside the rod. In the present invention, by moving the device, the hollow insert rod pierces the greenhouse film, then the electric heating ring is activated, and the L-shaped pull rod is pulled to move to the right, so that the electric heating ring can be in contact with the greenhouse film to open a hole, and the circular greenhouse film is sleeved in the hollow. In this way, the operation is more convenient and labor-saving, so that the work efficiency is high.

Description

technical field [0001] The invention relates to a hole opening device, in particular to a hole opening device for greenhouse ventilation. 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 film to cover hotbeds, and then covered sheds and greenhouses with good results. my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used in Beijing to cover vegetables in small sheds, and achieved the effect of early maturity and increased yield. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of the greenhouse has become more and more extensive. When a large number of crops are planted in the greenhouse, in order to ensure the normal growth of the crops, an appropr...
