Description

Technical Field

[0001] The utility model relates to the field of greenhouses, and particularly relates to an adjustable greenhouse. Background Art

[0002] A greenhouse, that is, a greenhouse shed, is a facility structure for cultivating plants or raising animals. It is usually composed of a framework and covering materials. The framework is generally built with metal, wood or other sturdy materials, and has various shapes, such as arch-shaped, semi-circular, etc. The covering materials mainly include plastic film, glass, sunlight board, etc. These materials can allow a certain amount of sunlight to pass through, and at the same time play roles such as heat preservation, moisture preservation, wind prevention, and rain prevention.

[0003] Chinese Patent Publication Application No.: CN202323644661.1 provides an ecological agriculture planting greenhouse. In this solution, by starting the motor, the motor drives the rotating rod, the rotating rod drives the fixed rod to rotate, the fixed rod drives the movable rod, and the movable rod drives the cleaning block to clean the sieve plate inside the water storage tank. The slider on the back of the cleaning block slides on the inner wall of the chute to limit the movement track of the cleaning block. By starting the water pump, the water pump pumps out the water in the water storage tank through the water suction pipe, injects the water into the integration pipe through the water delivery pipe, the water is injected into the nozzle through the integration pipe, and the water is sprayed out through the nozzle, so as to improve the quality of irrigation water and realize the spraying operation, meeting the use requirements of workers. However, in actual use, it is necessary to ventilate or close the air inside the greenhouse to meet the requirement of adjusting the temperature and humidity inside the greenhouse. Especially for plastic film greenhouses, generally when ventilation is needed, the plastic film is manually rolled up, and when heat preservation is needed by closing the air, the plastic film is also manually put down, so as to facilitate the ventilation inside the greenhouse, but it is not convenient to freely adjust the length of the plastic film, and it is quite laborious.

[0004] Therefore, we propose an adjustable greenhouse. Content of the Utility Model

[0025] Referring to Figures 1-4 as shown, a kind of adjustable greenhouse in a preferred embodiment of the present utility model includes a pair of symmetrically distributed film cloth retracting and deploying components 1 and a pair of symmetrically distributed greenhouse components 2. The film cloth retracting and deploying component 1 includes a machine box 101. Inside the machine box 101, a pair of left - right symmetric partition boards 102 are fixedly connected. The top ends of the partition boards 102 are rotatably connected to a shaft rod 103. The left and right ends of the shaft rod 103 are both rotatably connected to the machine box 101. Inside the machine box 101 and outside the partition boards 102, a pair of tape springs 104 are installed. Both of the pair of tape springs 104 are wound around the middle of the shaft rod 103. The greenhouse component 2 includes a greenhouse bracket 201 and a limit rod 202. A plurality of equally - spaced slots are provided on the outer wall of the greenhouse bracket 201. A rod sleeve 203 is sleeved in the middle of the limit rod 202. The rod sleeve 203 is rotatably connected to the limit rod 202. The limit rod 202 is adapted to the slots. The middle of the rod sleeve 203 is fixedly connected to a greenhouse film 204. The greenhouse film 204 is adapted to the greenhouse bracket 201. One end of the greenhouse film 204 is fixedly connected to the middle of the rod sleeve 203.

[0026] The shape of the greenhouse bracket 201 is arc - shaped.

[0027] An opening is provided at the bottom end of the machine box 101, and the opening is adapted to the greenhouse film 204.

[0028] The machine box 101 is located at the top end of the greenhouse support 201, and the machine box 101 is fixedly connected to the greenhouse support 201.

[0029] One end of the ruler spring 104 is fixedly connected to the shaft rod 103, and the end of the ruler spring 104 far from the shaft rod 103 is fixedly connected to the machine box 101.

[0030] One end of the greenhouse film 204 far from the rod sleeve 203 penetrates through the opening of the machine box 101 and is fixedly connected to the middle part of the shaft rod 103.

[0031] A pair of ruler springs 104 are respectively installed in the middle of the shaft rod 103 and on both sides of the greenhouse film 204.

[0032] Specific implementation process: The film cloth winding and unwinding assembly 1 drives the shaft rod 103 to rotate by using the elastic potential energy of the ruler spring 104 to realize the winding of the greenhouse film 204, which is stored in the machine box 101. When releasing, manually pull the greenhouse film 204 to make the shaft rod 103 rotate against the elastic force of the ruler spring 104 to store potential energy for subsequent winding. In the greenhouse assembly 2, by pulling the limit rod 202 to drive the rod sleeve 203 and the greenhouse film 204, the limit rod 202 is clamped into different card slots of the greenhouse support 201 to limit the position of the greenhouse film 204, and then the length of the greenhouse film 204 is adjusted to meet the requirements of greenhouse ventilation or airtightness, etc.;

[0033] In terms of the film cloth winding and unwinding assembly 1, a pair of tape springs 104 inside the machine box 101 are wound around the middle part of the shaft rod 103. One end of the tape spring 104 is fixedly connected to the shaft rod 103, and the other end is fixedly connected to the machine box 101. When it is necessary to wind up the greenhouse film 204, the elastic potential energy stored in the tape spring 104 is released, thereby driving the shaft rod 103 to rotate. Since one end of the greenhouse film 204 is fixedly connected to the middle part of the shaft rod 103, as the shaft rod 103 rotates, the greenhouse film 204 will gradually wind around the shaft rod 103, and finally the winding operation of the greenhouse film 204 is realized. The machine box 101 plays a good role in storage, ensuring that the wound greenhouse film 204 can be neatly placed inside. When it is necessary to release the greenhouse film 204, the greenhouse film 204 is manually pulled. At this time, the shaft rod 103 will rotate against the elastic force of the tape spring 104. In this process, the tape spring 104 is stretched to store elastic potential energy, preparing for the subsequent winding action. For the greenhouse component 2, a plurality of equally spaced card slots are provided on the outer wall of the arc-shaped greenhouse bracket 201. A rod sleeve 203 is sleeved in the middle of the limit rod 202, and the rod sleeve 203 is rotatably connected to the limit rod 202. When it is necessary to adjust the length of the greenhouse film 204, by pulling the limit rod 202, the limit rod 202 will drive the rod sleeve 203, and the rod sleeve 203 will drive the greenhouse film 204. When the limit rod 202 is pulled downward, the greenhouse film 204 is torn open. According to actual needs, after the greenhouse film 204 is torn to an appropriate length, the limit rod 202 is stuck in the corresponding card slot of the greenhouse bracket 201, so that the position of the greenhouse film 204 can be limited, and thus the adjustment of the length of the greenhouse film 204 is realized. In this way, the ventilation or airtightness requirements of the greenhouse under different conditions can be met, creating suitable environmental conditions for the growth of crops in the greenhouse.
