Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse snow removal equipment, and more specifically to a snow removal device for the top of a greenhouse. Background Technology

[0002] A greenhouse is an agricultural facility that uses artificial means to create a suitable environment for crop growth. It can regulate environmental factors such as light, temperature, humidity and gas composition inside the greenhouse, providing relatively stable and controllable conditions for crop growth, thereby breaking the limitations of seasons and regions and realizing off-season planting and high-efficiency production of crops.

[0003] In winter, snow accumulates on the roofs of greenhouses. The weight of the snow puts extra pressure on the greenhouse frame. If too much snow accumulates, exceeding the frame's load-bearing capacity, the greenhouse may collapse. Furthermore, snow accumulation on the greenhouse roof blocks sunlight, reducing light intensity inside and affecting crop growth. Therefore, clearing snow from the greenhouse roof is essential. Currently, people mainly clear snow from greenhouse roofs manually. This method is labor-intensive, inefficient, and has poor snow removal results.

[0004] Therefore, how to provide a greenhouse roof snow removal device with a high degree of automation, fast snow removal speed, and low labor cost is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a snow removal device for the top of a greenhouse, which solves the technical problem that manually clearing snow from the top of a greenhouse consumes a lot of manual labor and is slow.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A snow removal device for the top of a greenhouse includes a greenhouse body, a movable support, a rotating screw, a guide slide, a movable seat, a drive unit, an arc-shaped strip, and a brush layer. The greenhouse body is arched. The movable support spans the top of the greenhouse body and can move along the length of the greenhouse body. The rotating screw is horizontally arranged and rotatably connected to the top of the movable support along the length of the greenhouse body. The guide slide is fixed to the top of the movable support parallel to the rotating screw. The movable seat is slidably mounted on the guide slide and threadedly connected to the rotating screw. The drive unit is mounted on the movable support corresponding to the rotating screw, and its output shaft is fixedly connected to one end of the rotating screw to drive the movable seat to move along the length of the greenhouse body. The arc-shaped strip has elastic deformation and is detachably mounted on the bottom of the movable seat. Its arc-shaped concave opening is arranged downwards and is adapted to the curvature of the top end face of the greenhouse body. The brush layer is fixed to the arc-shaped concave surface of the arc-shaped strip and abuts and rubs against the top end face of the greenhouse body.

[0008] Through the above technical solution, this utility model discloses a snow removal device for greenhouse roofs. The greenhouse can be pre-divided into multiple sections along its length. When clearing snow from the roof of each section, the drive unit rotates a screw, causing an arc-shaped plate to move along the length of the greenhouse, following a moving base. A brush layer fixed to the concave surface of the arc-shaped plate moves to sweep the snow from the greenhouse roof. After clearing the snow from one section, the moving support is used to clear snow from the other sections. This utility model can automatically clear snow from the roof of greenhouses, has a high degree of automation, and can save a significant amount of manual labor.

[0009] Preferably, the movable support includes a gate-shaped support and movable wheels. There are two supports that are parallel to each other, and the movable wheels are installed at the bottom of both supports. The greenhouse body is located inside the gate-shaped frame of the two supports. The two ends of the rotating screw are respectively rotatably connected to the top of the opposite side of the two supports. The two ends of the guide slide are respectively fixed to the top of the opposite side of the two supports. The drive unit is installed on the outside of any of the supports, and its output shaft passes through the corresponding support and is fixedly connected to one end of the rotating screw.

[0010] The beneficial effect of adopting the above technical solution is that it makes it easier to move the curved strips to remove snow from each section of the greenhouse.

[0011] Preferably, the brush layer comprises multiple bundles of bristles evenly arranged along the circumference of the arc-shaped strip, with the top of each bundle of bristles fixed to the arc-shaped concave surface of the arc-shaped strip and the bottom end abutting and rubbing against the top end face of the greenhouse body.

[0012] Preferably, the bristles are made of polyethylene material.

[0013] The beneficial effects of adopting the above technical solution are that the brush bristles made of polyethylene material are soft and will not damage the top surface of the greenhouse, and are more wear-resistant and have a longer service life.

[0014] Preferably, a snow removal device for the top of a greenhouse further includes a blower mechanism, which includes a blower, an air duct, and an air outlet pipe; the blower is installed on the side wall of the arc-shaped slab; the air duct is opened inside the arc-shaped slab along its circumference and is connected to the air outlet end of the blower; there are multiple air outlet pipes evenly arranged along the circumference of the arc-shaped slab, one end of each air outlet pipe is inserted into the arc-shaped concave surface of the arc-shaped slab and connected to the air duct, and the other end is arranged corresponding to the top end face of the greenhouse body.

[0015] The beneficial effect of adopting the above technical solution is that while the brushes remove snow from the top of the greenhouse, the blower mechanism can disperse the snow, thereby improving snow removal efficiency.

[0016] Preferably, the center of the arc-shaped strip and the bottom of the movable seat are provided with multiple corresponding threaded holes, and high-strength bolts are threaded into the corresponding threaded holes.

[0017] The beneficial effect of adopting the above technical solution is that the curved strip can be quickly removed from the moving base for maintenance or replacement.

[0030] See appendix Figures 1 to 5This utility model discloses a snow removal device for the roof of a greenhouse, comprising a greenhouse body 100, a movable support 1, a rotating screw 2, a guide slide rod 3, a movable seat 4, a drive unit 5, an arc-shaped strip 6, and a brush layer 7. The greenhouse body 100 is arch-shaped. The movable support 1 spans across the top of the greenhouse body 100 and can move along the length of the greenhouse body 100. The rotating screw 2 is horizontally arranged and rotatably connected to the top of the movable support 1 along the length of the greenhouse body 100. The guide slide rod 3 is fixed to the top of the movable support 1 in parallel with the rotating screw 2. The seat 4 is slidably mounted on the guide slide rod 3 and threadedly connected to the rotating screw 2; the drive unit 5 is mounted on the movable bracket 1 corresponding to the rotating screw 2, and its output shaft is fixedly connected to one end of the rotating screw 2 to drive the movable seat 4 to move along the length of the greenhouse body 100; the arc-shaped strip 6 has elastic deformation and is detachably mounted on the bottom of the movable seat 4, with its arc-shaped concave opening facing downwards and matching the curvature of the top end face of the greenhouse body 100; the brush layer 7 is fixed on the arc-shaped concave surface of the arc-shaped strip 6 and abuts and rubs against the top end face of the greenhouse body 100.

[0031] The slight expansion and elastic deformation of the arc-shaped strip 6 allows the brush layer 7 to make full contact with the top surface of the greenhouse body 100.

[0032] In some embodiments, the movable support 1 includes a gate-shaped support 11 and movable wheels 12. There are two supports 11 that are parallel to each other. Movable wheels 12 are installed at the bottom of both supports 11. The greenhouse body 100 is located inside the gate-shaped frame of the two supports 11. The two ends of the rotating screw 2 are rotatably connected to the top of the opposite side of the two supports 11. The two ends of the guide slide rod 3 are fixed to the top of the opposite side of the two supports 11. The drive unit 5 is installed on the outside of any support 11, and its output shaft passes through the corresponding support 11 and is fixedly connected to one end of the rotating screw 2.

[0033] The movable support 1 can be movably mounted on the greenhouse body 100, making it easy for the brush layer 7, which is fixed to the bottom of the arc-shaped strip 6, to clean the snow on the top of each section of the greenhouse body 100.

[0034] In some embodiments, the brush layer 7 includes multiple bundles of bristles 71 evenly arranged along the circumferential direction of the arc-shaped strip 6. The top end of each bundle of bristles 71 is fixed to the arc-shaped concave surface of the arc-shaped strip 6, and the bottom end abuts and rubs against the top end face of the greenhouse body 100.

[0035] Specifically, the bristles 71 are made of polyethylene material.

[0036] The brush bristles 71, made of polyethylene material, are soft and more wear-resistant, will not damage the top surface of the greenhouse, and have a long service life.

[0037] In some embodiments, a greenhouse roof snow removal device further includes a blower mechanism 8, which includes a blower 81, an air duct 82, and an air outlet pipe 83. The blower 81 is installed on the side wall of the arc-shaped slab 6. The air duct 82 is opened inside the arc-shaped slab 6 along its circumference and is connected to the air outlet end of the blower 81. There are multiple air outlet pipes 83, which are evenly arranged along the circumference of the arc-shaped slab 6. One end of each air outlet pipe 83 is inserted into the arc-shaped concave surface of the arc-shaped slab 6 and connected to the air duct 82, and the other end is arranged corresponding to the top end face of the greenhouse body 100.

[0038] When the brush layer 7 follows the curved strip 6 to clear the snow on the top of the greenhouse body 100, the blower 81 can be controlled to blow strong wind into the air duct 82. The strong wind blows out from each air outlet pipe 83 to disperse the snow on the top of the greenhouse body 100, thus improving the snow removal efficiency.

[0039] In some specific examples, multiple corresponding threaded holes are provided at the center of the arc-shaped strip 6 and the bottom of the movable seat 4, and high-strength bolts 200 are threaded into the corresponding threaded holes.

[0040] The curved strip 6 is detachably installed on the bottom of the movable base 4 by high-strength bolts 200, which facilitates its disassembly and replacement.

[0041] In some other embodiments, a greenhouse roof snow removal device also includes a controller, which is electrically connected to the control terminal of the drive unit 5 and the blower 81.

[0042] The device is more automated by controlling the start and stop of the drive unit 5 and the blower 81 through the controller.

[0043] In use, the device first divides the greenhouse body 100 into multiple sections along its length, with each section being shorter than the distance between two supports 11. Then, the movable support 1 is moved to be positioned above the first section of the greenhouse body 100, and the drive unit 5 and blower 81 are started by the controller. Next, the arc-shaped strip 6 moves above the greenhouse body 100 along its length, following the movable seat 4. The brush layer 7 at the bottom of the arc-shaped strip 6 sweeps the snow off the top of the first section of the greenhouse body 100. During this process, the strong wind blown by the blower 81 disperses the snow on the top of the first section of the greenhouse body 100, improving snow removal efficiency. Finally, the movable support 1 is moved to clean the snow off the tops of the other sections of the greenhouse body 100 until all the snow is cleared.
