Description

Technical Field

[0001] This utility model belongs to the field of greenhouse technology, specifically, it relates to a snow melting and snow removal equipment for greenhouses. Background Technology

[0002] Snowfall is common in northern regions during winter. If snow falls on greenhouses and is not removed in time, it will affect the light received by the plants inside, easily cause low-temperature frost damage, prevent photosynthesis, and in severe cases, even cause the greenhouse to collapse. Therefore, it is essential to remove snow from greenhouses in a timely manner.

[0003] A document with publication number CN221627462U discloses a greenhouse snow-melting spraying device, relating to the field of facility agriculture technology. The device includes a low-pressure micro-sprayer pipe, a main water pipe, a water pipe fixing rope, a greenhouse crossbeam, a groundwater pipe, a pressure control valve, and a drainage ditch. One end of the low-pressure micro-sprayer pipe is connected to the main water pipe via a micro-sprayer pipe connector, and the other end is connected to a multi-hole nozzle. The spray holes are located on the front of the low-pressure micro-sprayer pipe. The main water pipe has a built-in water pipe fixing rope. The other end of the water pipe fixing rope is wrapped around the greenhouse quilt and fixed to the greenhouse crossbeam. The main water pipe passes through the greenhouse film and is connected to the groundwater pipe via a main water pipe connector. The groundwater pipe is located inside the greenhouse and has a built-in pressure control valve in the middle. The main water pipe is laid horizontally on the greenhouse film near the greenhouse crossbeam. The low-pressure micro-sprayer pipe is laid vertically on the greenhouse film in the middle of the greenhouse support. This device is time-saving, labor-saving, and provides timely snow melting with good results, making it suitable for winter greenhouse snow removal.

[0004] The aforementioned device melts snow by spraying groundwater, but in low-temperature environments, the water loses temperature rapidly after being extracted, and the remaining water freezes and is stored on the greenhouse. The frozen water exerts weight on the greenhouse and affects factors such as light transmission and temperature.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the technical problem of snow removal in greenhouses, the basic concept of the technical solution adopted by this utility model is as follows: A snow melting and snow removal device for greenhouses includes a greenhouse frame with a greenhouse film installed outside the frame; a snow removal component is installed inside the greenhouse frame and the greenhouse film, and is used to remove snow from the greenhouse film. The snow removal component includes a slide rail, a mounting base, a hot air pump, and a corrugated pipe. The slide rail is installed inside the greenhouse frame, the mounting base is slidably installed with the slide rail, the hot air pump is fixedly connected to the bottom of the mounting base, and the corrugated pipe is fixedly connected to the output end of the hot air pump.

[0007] In a preferred embodiment of this utility model, the mounting base is symmetrically provided with sliding wheel sets, each sliding wheel set is rotatably connected to the mounting base, and each sliding wheel set abuts against the slide rail.

[0008] In a preferred embodiment of this utility model, a first motor is fixedly connected to the mounting base, and the output end of the first motor is connected to a transmission belt through a coupling. The transmission belt is connected to the corresponding set of sliding wheels for transmission.

[0009] In a preferred embodiment of this utility model, a second motor is provided in the middle of the mounting base. The second motor is fixedly connected to the mounting base, and the output end of the second motor is connected to a drive disk through a coupling. An adjusting rod is slidably connected to the drive disk.

[0010] In a preferred embodiment of this utility model, the adjusting rod is V-shaped, the middle turning point of the adjusting rod is rotatably connected to the mounting base, the end of the adjusting rod is fixedly connected to the bellows, a connecting rod is fixedly connected to the adjusting rod, and a protrusion is fixedly connected to the connecting rod.

[0011] In a preferred embodiment of this utility model, a groove is provided on the drive disk. The groove is concave and the concave corners of the groove are arc-shaped.

[0012] In a preferred embodiment of this utility model, end blocks are symmetrically arranged at the ends of the slide rail, each end block is fixedly connected to the slide rail, and each end block is slidably connected to a movable frame.

[0013] In a preferred embodiment of this utility model, springs are symmetrically arranged between each end block and the movable frame, and the end of each spring is fixedly connected to the corresponding end block and the movable frame.

[0014] Compared with the prior art, the present invention has the following advantages: 1. This greenhouse snow melting and removal equipment combines two methods: hot air melting and mechanical intervention. Hot air directly heats the greenhouse film to melt the snow, and adjusting rods drive protrusions to create bumps, actively shaking off the melted snow. This dual action of "hot melting + mechanical" ensures thorough snow removal and effectively avoids the secondary icing problem that may be caused by traditional water-based snow melting methods.

[0015] 2. This type of greenhouse snow melting and snow removal equipment features a hot air pump that can move along a sliding rail to achieve linear sweeping heating. At the same time, the swinging of the adjusting rod will also cause the corrugated pipe of the air outlet to swing, further expanding the coverage of the hot air. This combination of "movement + swinging" design makes the heat distribution more uniform, significantly improving the overall snow removal efficiency and effect without significantly increasing energy consumption.

[0016] 3. This type of greenhouse snow melting and snow removal equipment has a buffer mechanism consisting of a movable frame and springs at the end of the moving parts. This mechanism can effectively absorb and buffer the impact force when the mounting base reaches the end of the stroke, which not only protects the equipment structure and reduces noise and wear, but also assists in its reverse start through the rebound force of the spring, ensuring the stability and reliability of the system's reciprocating operation.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0021] Please see Figure 1-5 A snow melting and snow removal equipment for greenhouses includes a greenhouse frame 1, with a greenhouse film 11 installed on the outside of the greenhouse frame 1; a snow removal component, which is installed inside the greenhouse frame 1 and the greenhouse film 11, and is used to remove snow from the greenhouse film 11. The snow removal component includes a slide rail 2, a mounting base 21, a hot air pump 3, and a corrugated pipe 31. The slide rail 2 is installed inside the greenhouse frame 1, the mounting base 21 is slidably installed with the slide rail 2, the hot air pump 3 is fixedly connected to the bottom of the mounting base 21, and the corrugated pipe 31 is fixedly connected to the output end of the hot air pump 3. When snow removal is needed, the mounting base 21 slides back and forth on the slide rail 2. The hot air pump 3 starts in advance to draw in air, heat it, and blow it out through the corrugated pipe 31. As the mounting base 21 moves back and forth, it drives the corrugated pipe 31 to heat the inside of the greenhouse film 11. By continuously heating the greenhouse film 11, the snow on the greenhouse film 11 melts. The snow cannot adhere to and deposit on the greenhouse film 11, thus achieving the effect of snow removal and avoiding the problem of water freezing caused by water melting snow.

[0022] The mounting base 21 is symmetrically provided with sliding wheel sets 24. Each sliding wheel set 24 is rotatably connected to the mounting base 21 and abuts against the slide rail 2. A first motor 22 is fixedly connected to the mounting base 21. The output end of the first motor 22 is connected to a transmission belt 23 through a coupling. The transmission belt 23 is connected to the corresponding sliding wheel set 24. A second motor 4 is provided in the middle of the mounting base 21. The second motor 4 is fixedly connected to the mounting base 21. The output end of the second motor 4 is connected to a drive disk 41 through a coupling. An adjusting rod 42 is slidably connected to the drive disk 41. The adjusting rod 42 is V-shaped. The turning point of the adjusting rod 42 is rotatably connected to the mounting base 21. The end of the adjusting rod 42 is fixedly connected to the bellows 31. A connecting rod 43 is fixedly connected to the adjusting rod 42. A protrusion 44 is fixedly connected to the connecting rod 43. A groove is opened on the drive disk 41. The groove is concave and the concave corners of the groove are arc-shaped. When snow removal is needed, the hot air pump 3 first draws in air, heats it, and then discharges it through the output end of the hot air pump 3 and the bellows 31. The output end of the first motor 22 drives the corresponding sliding wheel group 24 to rotate back and forth through the coupling and the transmission belt 23. The sliding wheel group 24 moves back and forth in the slide rail 2. The movement of the sliding wheel group 24 drives the mounting base 21. The mounting base 21 drives the hot air pump 3 and the bellows 31 to move. During the movement, the inner wall of the greenhouse film 11 is heated, the snow on the greenhouse film 11 melts, the snow cannot adhere to and deposit on the greenhouse film 11, and the snow slides off the greenhouse film 11, achieving the effect of snow removal and avoiding the problem of water freezing caused by water melting snow. During operation, the output end of the second motor 4 and the coupling drive the drive disc 41 to rotate. The rotation of the drive disc 41 guides the corresponding end of the adjusting rod 42 to move through the groove on it. The other end of the adjusting rod 42 drives the connecting rod 43 and the protrusion 44 to bounce intermittently. Through the bounce, the melted snow on the greenhouse film 11 is removed from the greenhouse film 11 by external force interference. The adjusting rod 42 drives the corrugated pipe 31 to swing to expand the range of hot air heat transfer and improve the snow removal effect. The rotation direction of the drive disk 41 is as follows: Figure 3 As a demonstration, drive disc 41 rotates clockwise.

[0023] The slide rail 2 is symmetrically provided with end blocks 5 at its ends. Each end block 5 is fixedly connected to the slide rail 2. Each end block 5 is slidably connected with a movable frame 51. Each end block 5 and the movable frame 51 are symmetrically provided with springs 52. The end of each spring 52 is fixedly connected to the corresponding end block 5 and the movable frame 51 respectively. During the sliding of the mounting base 21, the mounting base 21 moves to the end of the slide rail 2, and the slide rail 2 contacts the movable frame 51. The movable frame 51 compresses the corresponding spring 52, the spring 52 deforms, and applies the deformation force to the movable frame 51. The movable frame 51 restricts and buffers the movement force and movement of the mounting base 21, and applies a force in the opposite direction to accelerate the movement of the mounting base 21 and buffer the movement of the mounting base 21.

[0024] Working principle: When snow removal is needed, the hot air pump 3 first draws in air, heats it, and then discharges it through the output end of the hot air pump 3 and the bellows 31. The output end of the first motor 22 drives the corresponding sliding wheel group 24 to rotate back and forth through the coupling and the transmission belt 23. The sliding wheel group 24 moves back and forth in the slide rail 2, and the movement of the sliding wheel group 24 drives the mounting base 21. The mounting base 21 drives the hot air pump 3 and the bellows 31 to move. During the movement, the inner wall of the greenhouse film 11 is heated, and the snow on the greenhouse film 11 melts. The snow cannot adhere to and deposit on the greenhouse film 11 and slides off the greenhouse film 11, achieving the effect of snow removal and avoiding the problem of water freezing caused by water melting snow. During operation, the output end of the second motor 4 and the coupling drive the drive disc 41 to rotate. The rotation of the drive disc 41 is guided by the groove on it. The corresponding end of the adjusting rod 42 moves accordingly, and the other end of the adjusting rod 42 drives the connecting rod 43 and the protrusion 44 to bounce intermittently. Through the bounce, the melted snow on the greenhouse film 11 is removed from the greenhouse film 11 by external force interference. The adjusting rod 42 drives the corrugated pipe 31 to swing to expand the range of hot air heat transfer and improve the snow removal effect. During the sliding of the mounting base 21, the mounting base 21 moves to the end of the slide rail 2 and contacts the movable frame 51. The movable frame 51 compresses the corresponding spring 52, the spring 52 deforms, and applies the deformation force to the movable frame 51. The movable frame 51 restricts and buffers the movement force and movement of the mounting base 21, and applies a force in the opposite direction to accelerate the movement of the mounting base 21 and buffer the movement of the mounting base 21.
