Description

Technical Field

[0001] The invention belongs to the general field of building technology, and in particular relates to a greenhouse support for agricultural planting. Background Art

[0002] Greenhouse cultivation is a scientific planting method. It uses translucent covering materials as the enclosing structure to resist adverse weather conditions, create environmental conditions suitable for crop growth and development, and ensure that crops can grow and develop normally. Solar radiation enters the greenhouse through the translucent covering material, which increases the indoor ground temperature and air temperature. The temperature is blocked by the greenhouse covering material inside the greenhouse, thereby forming heat accumulation in the greenhouse, raising the temperature in the greenhouse, and providing temperature conditions suitable for the growth of plants in the greenhouse.

[0003] However, when using greenhouses for cultivation, due to the high temperature in the greenhouse and the large evaporation of water, a large amount of water vapor rises to the film on the top of the greenhouse and condenses. Due to the temperature difference between the inside and outside of the greenhouse film, water droplets gather on the inner surface of the greenhouse film, which directly affects the light from top to bottom and reduces the lighting conditions in the greenhouse. At the same time, due to the large specific heat of water droplets, the temperature in the greenhouse will rise slowly, affecting the photosynthesis of crops. Finally, the accumulation of a large number of water droplets will also increase the weight of the film covering the top of the greenhouse, causing the film to fall, affecting the service life of the greenhouse.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the greenhouse support for agricultural planting of the present invention includes a plurality of arc-shaped arch rods 1, and also includes:

[0029] A transverse plate member, the transverse plate member includes an upper transverse plate 2 arranged on the top of the arc-shaped arch rod 1 and a side transverse plate 3 arranged on the side of the arc-shaped arch rod 1, and both the upper transverse plate 2 and the side transverse plate 3 are provided with an insertion hole 101 for inserting the arc-shaped arch rod 1;

[0030] A plastic film 4, which is coated on the outer side of the arc-shaped arch rod 1 and movably abuts against the horizontal plate; and a shaking component, which is arranged on the upper horizontal plate 2;

[0031] Among them, an auxiliary water collection component connected to the shaking component is arranged on the upper horizontal plate 2.

[0032] Specifically, the greenhouse support is composed of a number of arc-shaped arch rods 1 inserted into the ground, and a horizontal plate is installed between the arc-shaped arch rods 1 for support and positioning, so that the plastic film 4 is covered on the outside of the arc-shaped arch rods 1 and the horizontal plate. When condensed water droplets appear on the inner side of the plastic film 4, the shaking component is controlled to operate, so that the shaking component drives the plastic film 4 to shake, so that the water droplets inside the plastic film 4 can slide down along the arc-shaped surface of the film, thereby effectively cleaning the water droplets on the film and reducing the cleaning workload of the staff, making the greenhouse film more light-transmitting, and improving the efficiency of photosynthesis of crops in the greenhouse. At the same time, it avoids the falling scene of the greenhouse film caused by hanging water droplets, further improving the service life of the agricultural greenhouse, and the shaking component drives the auxiliary water collection component to operate when working, so that the scattered water droplets on the plastic film 4 quickly gather and slide down, thereby improving the speed of clearing the water droplets on the plastic film 4.

[0033] Among them, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the shaking assembly includes a support base 5 fixed on the upper horizontal plate 2, a driving motor 501 fixed on the support base 5, a driving shaft 502 connected to the output end of the driving motor 501, a support plate 503 fixed on the upper horizontal plate 2, a rotating rod 504 rotatably connected to the support plate 503, a first synchronous wheel 505 arranged on the rotating rod 504 and the driving shaft 502, a first synchronous belt arranged between the two first synchronous wheels 505, a first U-shaped rod 5041 arranged on the rotating rod 504, and a rubber cam 506 arranged on the first U-shaped rod 5041 and movably abutting against the upper horizontal plate 2, and the driving shaft 502 is rotatably arranged on the support plate 503.

[0034] Specifically, when the shaking component is working, it controls the operation of the driving motor 501 so that the output end of the driving motor 501 drives the driving shaft 502 to rotate. When the driving shaft 502 rotates, it drives the rotating rod 504 to rotate through the first synchronous wheel 505 and the first synchronous belt. When the rotating rod 504 rotates, it drives the first U-shaped rod 5041 to rotate. When the first U-shaped rod 5041 rotates, it drives the rubber cam 506 to rotate. When the rubber cam 506 rotates, it will be against the bottom activity of the upper horizontal plate 2. The rubber cam 506 can be deformed when it contacts the upper horizontal plate 2 and pass over the upper horizontal plate 2 as it rotates. The upper horizontal plate 2 is hit by the rubber cam 506 and vibrates. The upper horizontal plate 2 drives the arc-shaped arch rod 1 and the plastic film 4 connected thereto to shake, so that the water droplets on the inner side of the plastic film 4 slide down along the arc-shaped surface of the film, thereby achieving effective cleaning of the water droplets on the film.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the auxiliary water collection assembly includes a working tube 7 arranged on the upper horizontal plate 2, a piston 701 slidably connected in the working tube 7, a moving rod 702 rotatably connected to the piston 701, a connecting rod 703 movably connected to one end of the moving rod 702 away from the piston 701, a connecting ring 704 arranged at the bottom of the connecting rod 703, and a second U-shaped rod 705 rotatably connected to the connecting ring 704 and fixedly connected to the rotating rod 504.

[0036] Furthermore, the piston 701 divides the working tube 7 into a pneumatic chamber 706 and a hydraulic chamber 707. The pneumatic chamber 706 is fixedly provided with an air inlet valve 7061. Air outlet valves 7062 are symmetrically arranged on both sides of the pneumatic chamber 706. The working tube 7 is provided with an air jet plate 7063 at the air outlet valve 7062.

[0037] Specifically, when the shaking component is working, it drives the auxiliary water collection component to move, so that the rotating rod 504 drives the second U-shaped rod 705 to rotate, and when the second U-shaped rod 705 rotates, it drives the connecting ring 704 to move, so that the connecting ring 704 drives the moving rod 702 to move up and down through the connecting rod 703, and the moving rod 702 drives the piston 701 to move up and down in the working tube 7. When the piston 701 moves up in the working tube 7, the pneumatic chamber 706 of the working tube 7 draws air in the shed through the air intake valve 7061. When the piston 701 moves down in the working tube 7, the air drawn in the pneumatic chamber 706 is squeezed, and the air is discharged through the jet plate 7063. The discharged air blows the water droplets on the plastic film 4, so that the scattered water droplets on the plastic film 4 quickly gather and slide down, thereby improving the speed of removing the water droplets on the plastic film 4.

[0038] like Figure 1 , Figure 2 and Figure 5As shown, a first water collecting bag 401 with an opening at the upper end is provided at the bottom of the inner side wall of the plastic film 4, and the first water collecting bag 401 is connected to the water storage tank 6 through a pipeline.

[0039] Specifically, under the action of the shaking component and the auxiliary water collection component, the water droplets on the inside of the plastic film 4 quickly gather and slide down along the curved surface of the film. The sliding water flows into the first water collection bag 401, preventing the water flow from sliding down along the curved surface of the film to the ground, making the ground damp and soft, affecting the stability of the greenhouse support and the ground, and guiding the water into the water storage tank 6 for watering and cleaning through the pipe on the lower side of the first water collection bag 401.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, a liquid inlet valve 7071 is provided on the hydraulic chamber 707, and a liquid inlet pipe 7072 connected to the water storage tank 6 is provided at the liquid inlet valve 7071. Liquid outlet valves 7073 are also symmetrically provided on both sides of the hydraulic chamber 707, and a nozzle 7074 is provided at the working tube 7 placed at the liquid outlet valve 7073.

[0041] Specifically, when the greenhouse plastic film 4 is used in winter, due to dry weather and strong winds, dust is easily attached to the greenhouse film, which makes the light transmittance of the greenhouse film poor, so that the plants in the greenhouse cannot receive good light. The piston 701 moves downward in the working tube 7 to extract water from the water storage tank 6 through the liquid inlet pipe 7072. When the piston 701 moves upward in the working tube 7, the extracted water can be sprayed on the outside of the plastic film 4 through the nozzle 7074. The sprayed water can wash away the dust attached to the outside of the plastic film 4. Since it is windy outdoors in winter, the moisture on the outside of the plastic film 4 can be quickly dried, increasing the light transmittance of the film, which is beneficial to the growth of plants in the greenhouse.

[0042] As shown Figure 1 , Figure 2 and Figure 5 A second water collecting bag 402 with an opening at the upper end is arranged at the bottom of the outer side wall of the plastic film 4, and the second water collecting bag 402 is connected to the sewage tank 8 through a pipeline.

[0043] Furthermore, a filter screen 801 is fixedly provided in the sewage tank 8 , and a connecting pipe 13 is connected between the sewage tank 8 and the water storage tank 6 , and a valve 131 is provided on the connecting pipe 13 .

[0044] Specifically, the working pipe 7 sprays water through the nozzle 7074 to wash away the dust attached to the outside of the plastic film 4. Since it is windy outdoors in winter, the moisture on the outside of the plastic film 4 can be quickly dried, and some of the undried water flows down along the curved surface of the film to the second water collecting bag 402, and enters the sewage trough 8 through the pipe, so as to prevent the water from sliding down along the curved surface of the film to the ground, making the ground damp and soft, and affecting the stability of the greenhouse support and the ground. The sewage entering the sewage trough 8 is filtered by the filter 801, and the impurities are intercepted by the filter 801. The staff can turn the valve 131 to allow the filtered water in the sewage trough 8 to enter the water storage tank 6 through the connecting pipe 13, thereby realizing the recycling of water resources and saving the cost of using water resources.

[0045] As shown Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 A support plate 9 is fixedly provided on the upper horizontal plate 2, and a rotating shaft 901 is rotatably connected to the support plate 9. A second synchronous wheel 10 is provided on the rotating shaft 901 and the rotating rod 504, and a second synchronous belt is provided between the two second synchronous wheels 10. A driving bevel gear 9011 is provided on the rotating shaft 901, and a driven bevel gear 11 meshing with the driving bevel gear 9011 is provided on the working tube 7.

[0046] Furthermore, the active bevel gear 9011 is arranged on the incomplete bevel gear, the working tube 7 is rotatably arranged in the upper transverse plate 2 , and a torsion spring 12 sleeved on the outside of the working tube 7 is arranged in the upper transverse plate 2 .

[0047] Specifically, when the rotating rod 504 rotates, the rotating shaft 901 is driven to rotate through the second synchronous wheel 10 and the second synchronous belt. When the rotating shaft 901 rotates, the active bevel gear 9011 at the end is meshed with the driven bevel gear 11 on the working tube 7 for transmission, so that the working tube 7 rotates relative to the upper cross plate 2. If the active bevel gear 9011 is set as a complete gear, the working tube 7 will continue to rotate in one direction, and the jet plate 7063 and the nozzle 7074 will not be directed to the plastic film 4 when working, resulting in waste of water resources and low efficiency in removing water droplets on the inner wall of the plastic film 4. Since the active bevel gear 9011 is set as an incomplete bevel gear, the working tube 7 only rotates when the active bevel gear 9011 is meshed with the driven bevel gear 11. When the active bevel gear 9011 is no longer meshed with the driven bevel gear 11, the working tube 7 is reset and rotated under the action of the torsion spring 12, thereby realizing reciprocating rotation of the working tube 7 within a certain range, preventing the occurrence of cleaning dead corners for the plastic film 4.

[0048] Working principle: When condensed water droplets appear on the inner side of the plastic film 4, the shaking component is controlled to operate. When the shaking component is operating, the driving motor 501 is controlled to operate, so that the output end of the driving motor 501 drives the driving shaft 502 to rotate. When the driving shaft 502 rotates, it drives the rotating rod 504 to rotate through the first synchronous wheel 505 and the first synchronous belt. When the rotating rod 504 rotates, it drives the first U-shaped rod 5041 to rotate. When the first U-shaped rod 5041 rotates, it drives the rubber cam 506 to rotate. When the rubber cam 506 rotates, it will be against the bottom activity of the upper cross plate 2. The rubber cam 506 can be deformed when it contacts the upper cross plate 2 and pass over the upper cross plate 2 as it rotates. The upper cross plate 2 is hit by the rubber cam 506 and vibrates. The upper cross plate 2 drives the arc arch rod 1 and the plastic film 4 connected thereto to shake, so that the water droplets on the inner side of the plastic film 4 slide down along the arc surface of the film, thereby achieving effective cleaning of the water droplets on the film.

[0049] When the shaking component is working, it drives the auxiliary water collecting component to move, so that the rotating rod 504 drives the second U-shaped rod 705 to rotate, and when the second U-shaped rod 705 rotates, it drives the connecting ring 704 to move, so that the connecting ring 704 drives the moving rod 702 to move up and down through the connecting rod 703, and the moving rod 702 drives the piston 701 to move up and down in the working tube 7. When the piston 701 moves up in the working tube 7, the pneumatic cavity 706 of the working tube 7 draws air in the shed through the air inlet valve 7061. When the piston 701 moves down in the working tube 7, the air drawn in the pneumatic cavity 706 is squeezed, and the air is discharged through the jet plate 7063. The discharged air blows the water droplets on the plastic film 4, so that the scattered water droplets on the plastic film 4 quickly gather and slide down, thereby improving the speed of removing the water droplets on the plastic film 4.

[0050] The water droplets on the inner side of the plastic film 4 quickly gather and slide down along the curved surface of the film. The sliding water flows into the first water collecting bag 401, preventing the water from sliding down along the curved surface of the film to the ground, making the ground damp and soft, affecting the stability of the greenhouse support and the ground, and guiding the water into the water storage tank 6 for watering and cleaning through the pipe on the lower side of the first water collecting bag 401.

[0051] When the piston 701 moves downward in the working tube 7, the water in the water storage tank 6 can be extracted through the liquid inlet pipe 7072. When the piston 701 moves upward in the working tube 7, the extracted water can be sprayed on the outside of the plastic film 4 through the nozzle 7074. The sprayed water can wash away the dust attached to the outside of the plastic film 4. Since it is windy outdoors in winter, the moisture on the outside of the plastic film 4 can be quickly dried, thereby increasing the light transmittance of the film, which is beneficial to the growth of plants in the shed.
