Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse equipment, in particular to a roller curtain machine for a temperature and humidity greenhouse for vegetables. Background Art

[0002] Greenhouse vegetables refer to melons and vegetables grown in controlled environments such as greenhouses and canopies. They overcome the limitations of the natural environment through technical means to achieve efficient production. Vegetables cultivated in facilities include eggplants, melons, beans, cabbages, Chinese cabbages, onions, garlic, leafy vegetables and other major categories, covering hundreds of different vegetables. Plants receive light through plastic sheets during the day, but at night, a straw curtain or insulation blanket needs to be added to the plastic sheet to prevent the crops from freezing to death on cold nights. The use of greenhouses allows crops to grow in winter, and at night, an insulation layer needs to be added to the plastic sheet to prevent the temperature in the greenhouse from being too low to prevent the crops from freezing to death, and the insulation layer needs to be put away during the day.

[0003] In the utility model patent with patent announcement number CN214902491U, the second bevel gear and the first bevel gear are set so that the two reels can rotate simultaneously in opposite directions. When the two reels rotate at the same time, the two insulation layers can be retracted at the same time, thereby solving the problem in the prior art that the two insulation layers cannot be retracted at the same time. By retracting the two insulation layers at the same time, the time for retracting the insulation layers can be reduced. Although this method can solve the reeling problem, the above-mentioned mechanism is installed on the top of the greenhouse and occupies the sunlight exposure area on the top of the greenhouse. Even after the insulation cloth is rolled up, it will still affect the sunlight exposure during the day, which is not suitable for practical use. In addition, if the reeling mechanism is placed entirely on the top of the greenhouse, there is a risk of crushing the greenhouse support poles for a long time.

[0004] Therefore, it is necessary to provide a kind of facility vegetable temperature and humidity greenhouse roller shutter machine to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a vegetable temperature and humidity greenhouse roller shutter machine to solve the problem that although the existing device can solve the rolling problem, the above mechanism is installed on the top of the greenhouse and occupies the sunlight exposure area on the top of the greenhouse. Even after the insulation cloth is rolled up, it will still affect the sunlight exposure during the day, which is not suitable for practical use. Moreover, if the rolling mechanism is placed entirely on the top of the greenhouse, there is a risk of crushing the greenhouse support poles for a long time.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A roller blind machine for a vegetable temperature and humidity greenhouse, comprising: a support frame;

[0008] The support frames are arranged in multiple groups at intervals, the inner circumference of the support frames is in contact with the top surface of the greenhouse, the support frame as a whole is a semicircular frame plate structure, and a limiting groove is provided on its outer circumference. A first winding box is installed at the bottom right of the support frame, and a second winding box is installed at the bottom left. The first winding box and the second winding box have built-in winding shafts, and the sides of the first winding box and the second winding box are both provided with drive boxes. The first winding box is used to wind up the thermal insulation cloth, and the second winding box is used to wind up the traction rope. An end plate is installed at the end of the thermal insulation cloth, and the top of the end plate is installed and connected to the end of the traction rope in the second winding box.

[0009] In one embodiment, the inner circumference of the support frame is open, and the limiting grooves are provided so that the corresponding inner side walls of the support frame form a connecting surface.

[0010] In one embodiment, a guide wheel is installed on the side of the end plate facing the limiting groove, the guide wheel passes through the limiting groove, and the two side circumferences of the guide wheel are in contact with the connecting surface.

[0011] In one embodiment, a limiting pulley is installed in the limiting groove, and the traction rope is placed inside the limiting pulley.

[0012] In one embodiment, the first winding box and the second winding box are both installed inside the ground on both sides of the greenhouse by bolts, and the top surfaces of the two boxes protrude from the ground.

[0013] In one embodiment, a motor is disposed inside the driving box, a first pulley is mounted on the rotating shaft of the motor, a second pulley is mounted on the winding shaft, and belts are mounted on the first pulley and the second pulley.

[0014] The beneficial effects of the utility model are as follows:

[0015] When covering is needed, the second winding box of the utility model winds up the traction rope, and the first winding box rotates in the opposite direction to release the insulation cloth, so that the traction rope pulls the end plate and the insulation cloth to move along the path of the support frame, thereby covering the greenhouse below with the insulation cloth. When winding is needed, the above-mentioned mechanism can work in the reverse direction. Through the structural setting of the utility model, the problem of crushing the greenhouse frame will not occur. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0023] like Figure 1-5 As shown, the utility model provides a kind of facility vegetable temperature and humidity greenhouse roller shutter machine, comprising: a support frame 1, a first winding box 2, a second winding box 3, an insulation cloth 4, an end plate 5, and a traction rope 6; the support frame 1 is arranged in multiple groups at intervals, the inner circumference of the support frame 1 is in contact with the top surface of the greenhouse, the support frame 1 is a semicircular frame plate structure as a whole, and a limiting groove 11 is provided on its outer circumference, the first winding box 2 is installed at the bottom right of the support frame 1, and the second winding box 3 is installed at the bottom left, the first winding box 2 and the second winding box 3 have a winding shaft 17 built in, the first winding box 2 and the second winding box 3 are both provided with a drive box 14, and a motor is provided inside the drive box 14, The motor drives the winding shaft 17 to rotate through a belt or gear. The first winding box 2 is used to wind up the insulation cloth 4, and the second winding box 3 is used to wind up the traction rope 6. The insulation cloth 4 is a non-transparent insulation cloth. The end of the insulation cloth 4 is installed with an end plate 5, and the top of the end plate 5 is installed and connected to the end of the traction rope 6 in the second winding box 3. During operation, when covering is required, the second winding box 3 winds up the traction rope 6, and the first winding box 2 rotates in the opposite direction to release the insulation cloth 4, so that the traction rope 6 pulls the end plate 5 and the insulation cloth 4 to move along the path of the support frame 1, thereby covering the greenhouse below with the insulation cloth. When winding is required, the above-mentioned mechanism can work in reverse.

[0024] Preferably, in one embodiment, Figure 3 As shown, the inner circumference of the support frame 1 is open, and the opening of the limiting groove 11 enables the corresponding inner side wall of the support frame 1 to form a connecting surface 12.

[0025] Preferably, in one embodiment, a guide wheel 51 is installed on the side of the end plate 5 facing the limiting groove 11, and the guide wheel 51 passes through the limiting groove 11. The two side circumferential surfaces of the guide wheel 51 are in contact with the connecting surface 12. When the traction rope 6 pulls the end plate 5 to move, the guide wheel 51 is in contact with the connecting surface 12 and moves, so that the thermal insulation cloth 4 effectively covers the outer circumferential surface of the support frame 1.

[0026] Preferably, in one embodiment, a limiting pulley 13 is installed in the limiting groove 11, and the traction rope 6 is placed inside the limiting pulley 13, so as to provide a corresponding sliding force when the traction rope 6 moves, thereby avoiding rigid friction damage.

[0027] Preferably, in one embodiment, the first winding box 2 and the second winding box 3 are both installed inside the soil on both sides of the greenhouse by bolts, and the top surfaces of both protrude from the ground, so as to maximize the coverage of the insulation cloth 4 and avoid gaps.

[0028] Preferably, in one embodiment, a motor 15 is provided inside the drive box 14, a first pulley 16 is installed on the rotating shaft of the motor 15, a second pulley 18 is installed on the winding shaft 17, a belt 19 is installed on the first pulley 16 and the second pulley 18, when the winding shaft 17 needs to be rotated, the motor 15 is started, and after the motor 15 is started, it drives the first pulley 16 to rotate, the first pulley 16 drives the second pulley 18 to rotate through the belt 19, the rotation of the second pulley 18 drives the winding shaft 17 to rotate, and the rotation of the winding shaft 17 drives the traction rope 6 or the insulation cloth 4.

[0029] Working principle of this utility model:

[0030] The total length of the device is between 10 and 20 meters. A greenhouse requires multiple devices to be used in conjunction with each other end to end. No other fixings are required for the connection. Compared with an integral structure (i.e., one roller shutter for a greenhouse), the device is more flexible to use and can be selected in corresponding quantities according to the length of the greenhouse. Sometimes, some shade-loving plants and some sun-loving plants may be planted in a greenhouse. During use, the laying or winding of the insulation cloth can be controlled according to the specific plants. When covering is required, the second winding box 3 winds up the traction rope 6, and the first winding box 2 rotates in the opposite direction to release the insulation cloth 4, so that the traction rope 6 pulls the end plate 5 and the insulation cloth 4 to move along the path of the support frame 1, thereby covering the greenhouse below with the insulation cloth. When winding is required, the above mechanism can work in the opposite direction.

[0031] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
