Description

Plastic shed film uncovering device

(1) Technical field

The utility model belongs to the technical field of accessory devices for plastic greenhouses used in agriculture, forestry and gardening, and particularly relates to a plastic greenhouse film uncovering device that can quickly uncover and restore plastic greenhouse films.

(2) Background technology

Currently, the existing plastic greenhouse film uncovering devices are all partial opening and closing types, and they can only uncover and cover the plastic film of a limited area near the side or top of the plastic greenhouse. The opening and closing device of the plastic film for the side window of the plastic greenhouse disclosed in Japanese Patent Opening No. 54-75339, the PGP series plastic greenhouse side rolling ventilation window etc. published in the 9th issue of "Agricultural Machinery" in 1982 in my country all belong to this type of part. Open and close type uncovering benefit device, the area that these uncovering devices uncover is less, not very convenient.

In agricultural and forestry production, the use of plastic greenhouses is different from the local and current climate and environment conditions. Sometimes the plastic film of the plastic greenhouse can be easily and quickly completely or mostly uncovered; on the contrary, after opening, the film needs to be easily restored. Cover and fasten firmly. Known plastic shed film uncovering device can not satisfy above-mentioned needs. Some plastic greenhouses have to use auxiliary measures such as exhaust fans to carry out forced ventilation and cooling, which increases equipment investment and energy consumption as a result. However, the rain-shielding plastic sheds for agricultural water testing mostly adopt the existing mobile structure. When it rains, it is pushed along the track to the test site for covering, and it is removed when there is no rain. As a result, the manufacturing cost of this shed is increased. The utilization rate of the ground is reduced; at the same time, due to the limitation of the rigidity of the shed body, the area of this mobile rain-shielding plastic shed is small. The test results are greatly affected by the conditions such as soil moisture around the shed, and the test results are inaccurate.

(3) Contents of the invention

In order to solve the problems in the prior art, the utility model provides a fully open and close plastic shed film uncovering device that can be quickly uncovered.

The utility model is achieved through the following measures: a plastic shed film uncovering device, including ground anchor components, lamination lines, skirt film, plastic shed film, a roll film rod for winding the plastic shed film, The reel at one end and the pull rope wound on the reel are fixed on the outside of the plastic shed by a bracket to drive a motor that can drive the reel to rotate, and the bottom of the outer side of the plastic shed is fixed with an elastic that can relax and tension the lamination line Mechanism, the elastic mechanism includes a reducer, a rotating shaft, and a crank.

The beneficial effects of the utility model:

1. The fully open and close type can be quickly uncovered, which can not only reduce labor intensity, but also improve work efficiency;

2. The structure is simple, the operation is convenient, the cost is low, and it is suitable for popularization and application.

(4) Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail.

Fig. 1 is the structural representation of the utility model.

In the figure, 1 reducer, 2 crank, 3 ground anchor assembly, 4 laminating line, 5 rotating shaft, 6 bracket, 7 skirt film, 8 plastic shed film, 9 gable film, 10 film rod, 11 reel, 12 pull rope, 13 motors.

(5) Specific implementation methods

A plastic shed film uncovering device as shown in Figure 1, including ground anchor assembly 3, laminating line 4, skirt film 7, plastic shed film 8, film roll rod 10 for winding plastic shed film 8, located at the roll film The reel 11 at one end of the bar 10 and the stay cord 12 wound on the reel 11 are fixed with a motor 13 that can drive the reel 11 to rotate by a bracket 6 outside the plastic greenhouse, and the bottom of the plastic greenhouse outer side is fixed with a motor 13 that can make the pressure An elastic mechanism for loosening and tensioning the film line 4.

The elastic mechanism includes a reducer 1, a rotating shaft 5, and a handle 2. The rotating shaft 5 is arranged at the bottom of the outside of the greenhouse, and its axis is parallel to the longitudinal axis of the plastic greenhouse, perpendicular to the gable of the greenhouse and the gable film 9. One end of the line 4 is wound on the rotating shaft 5, the other end of the laminating line 4 is tied to the ground anchor on the other side of the shed body, the reducer 1 is a worm gear reducer, which has a self-locking function, and the shaking handle 2 is driven by the reducer 1 The rotating shaft 5 tensions the laminating line 4 along the shed surface, and simultaneously compresses the plastic shed film 8 .

A reel-type film rolling mechanism is fixed on the outside of the plastic greenhouse. The reel-type film rolling mechanism includes a film-rolling rod 10, a reel 11, a pull cord 12 and a motor 13. When the motor 13 drives the film-rolling rod 10 to rotate clockwise The stay cord 12 is tightened to roll up the plastic shed film 8, and when the motor 13 drives the film rolling rod 10 to rotate counterclockwise, the stay cord 12 relaxes to cover the plastic shed film 8 to the original position.
