specific Embodiment approach 1

[0007] Specific implementation mode one: combine Figure 1 ~ Figure 3 Describe this embodiment, the fixing and releasing device of the greenhouse plastic film of this embodiment is made up of two steel pipes 1, a plurality of ropes 2, a plurality of pull rings 3 and at least two groups of fixed releasers, and at least two groups of fixed releasers are arranged side by side Set, each set of fixed releasers is composed of two fixed releasers 4, the two fixed releasers 4 are arranged in the same direction, each fixed releaser 4 includes a base 5, a positioning seat 6, a steel pipe fixing ring 7, and a pull rod 8 and the rod seat 9, the rod seat 9 and the positioning seat 6 are fixed on the base 5 along the length direction of the base 5, one end of the rod 8 is mounted on the rod seat 9 in rotation, and the other end of the rod 8 is installed on the positioning On the seat 6, the steel pipe fixing ring 7 is installed on the end of the pull rod 8 close to the positioning seat 6. A...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination Figure 2 ~ Figure 4 To illustrate this embodiment, each fixed release device 4 of this embodiment is also increased with a limit pin 10, and a pin hole 9-1 is opened on the tie rod seat 9, and the pin hole 9-1 is opened on the tie rod seat 9 and positioned close to it. On one end of the seat 6, the limit pin 10 is installed in the pin hole 9-1. Arranged in this way, the limit pin 10 is used to prevent the pull rod 8 from lying down automatically when the pull rod 8 stands up. Other compositions and connections are the same as in the first embodiment.

[0009] The working principle of the fixed release device of the present invention is as follows (see Figure 1 ~ Figure 4 ): a fixed release device 4 of the present invention is installed on the back wall edge of the plastic greenhouse 11, and another fixed release device 4 is installed on the lower foot of the plastic greenhouse 11, and the pull rod 8 is laid down, and the...

Abstract

The invention relates to a fixed releasing device of a greenhouse high tunnel plastic film, which solves the problem that the existing fixing device of the high tunnel plastic film has no releasing function; in the invention, at least two fixed releasing devices are arranged forth and back along the same direction, a draw bar base and a locating base are fixed on a base, one end of a draw bar is rotationally arranged on the draw bar base, the other end of the draw bar is arranged on the locating base, a steel pipe fixing ring is arranged at one end of the draw bar, close to the locating base, two steel pipes are arranged in the steel pipe fixing rings of the two fixed releasing devices, a plurality of pull rings are arranged on each steel pipe along the length direction, and the pull rings on the two steel pipes are arranged correspondingly, and the two corresponding pull rings are connected by a rope; the fixed releasing device has the releasing function and has the advantages of simple structure, simple operation and labor and time saving.

Description

technical field [0001] The invention relates to a fixing and releasing device for a plastic film in a greenhouse. Background technique [0002] The current plastic film in the greenhouse is fixed by steel bars, and the tightness of the plastic film is adjusted by bolts, but the adjustable range is very small, and the ventilation control in the normal growing season of crops is extremely limited, and can only be controlled within a range of about one meter near the ground. During the adjustment process, it is very easy to cause damage to the plastic film. Due to the difficulty in ventilation regulation, serious pests and diseases occur in the greenhouse, and it is difficult to use natural rainfall. The current plastic film in the greenhouse has a fixing device, but it lacks a release function. When the temperature in the greenhouse is too high and the covering area of ​​the plastic film needs to be adjusted, the plastic film is difficult to open, which takes time and effort,...
