Description

Technical Field

[0001] The present invention relates to the technical field of greenhouse rice planting spraying equipment, and in particular to a rice factory spraying device based on photovoltaic power generation. Background Art

[0002] In the agricultural field, in order to meet the large demand for vegetables of the domestic population, large-scale greenhouse breeding bases have gradually emerged in various places. However, my country's current greenhouse cultivation is basically operated manually. Field management during the crop growth period and the subsequent sale of vegetables require direct human participation. For example, irrigation and fertilization during the growth process of crops are all carried out manually.

[0003] Chinese patent CN215912709U discloses a greenhouse spraying device, comprising a greenhouse body, a track assembly, a traveling assembly, and a spraying mechanism; the greenhouse body comprises a plurality of brackets; the top of the track assembly is fixedly connected to the brackets; the traveling assembly is mounted on the track assembly, and the traveling assembly moves translationally along the track assembly; the spraying mechanism is mounted on the bottom of the traveling assembly; a plurality of spray heads are provided at the bottom of the spraying mechanism, a water inlet pipe joint is provided on one side of the spraying mechanism, and the plurality of spray heads are connected to the water inlet pipe joint; the water inlet pipe joint is used to connect to an external water inlet pipe. This utility model can automatically spray water or fertilize in a greenhouse, eliminating the trouble of manual spraying, saving manpower and time. The greenhouse spraying device is provided with a traveling assembly mounted on the top of the greenhouse body via a track assembly, and the spraying mechanism is mounted on the traveling assembly. As the traveling assembly moves translationally, the spraying mechanism automatically sprays the crops in the greenhouse body, eliminating the trouble of manual spraying, saving manpower and time.

[0004] However, the referenced document still has the following issues: 1. It cannot achieve precise spraying for crops at different heights. 2. When the sprinkler mechanism is in motion, it will spray water onto the aisle, resulting in a waste of water resources and making the aisle slippery and inconvenient for workers to pass through. It also cannot accurately control the automatic opening and closing of the water. Summary of the Invention

[0009] Preferably, the linear drive mechanism includes a mounting seat, a second power device and a second screw rod; the mounting seat is fixedly mounted on both sides of the first screw rod; the second power device is arranged inside the mounting seat, and the output end of the second power device is connected to the second screw rod; a slide is provided on the second screw rod, and a water tank is fixedly provided on the slide; the water tank is connected to the spray mechanism.

[0010] Preferably, spray mechanisms are provided on both sides of the water tank.

[0011] Preferably, the side wall of the height adjustment mechanism is provided with a support assembly, and the support assembly includes a support seat, a support block and a spring; the support seat is arranged on the crossbeam plate at the top of the greenhouse; the support block is arranged below the mounting seat; the support block and the mounting seat are an integrated structure; a support groove is provided inside the support seat; one end of the spring is fixed to the bottom of the support groove, and the other end is fixedly connected to the bottom of the support block.

[0013] Preferably, the pulling assembly includes a pull rod and a sliding block; one end of the pull rod on both sides is fixedly connected to the top of the spray seat on both sides, and the other end is connected to the sliding block; a sliding groove is provided on the top of the mounting seat, and the sliding block is slidably provided in the sliding groove.

[0014] Preferably, the photovoltaic panels are spaced apart on both sides of the top of the greenhouse; a light-diffusing plate is provided between adjacent photovoltaic panels; and the light-diffusing plate is used to disperse sunlight.

[0015] Preferably, the slide plate is fixedly arranged on the side wall of the mounting seat.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The height adjustment mechanism of this invention controls the height of the entire spray mechanism, allowing for targeted spraying of experimental rice fields at varying heights, improving spraying effectiveness and promoting rice growth. When passing through aisles, a water flow control assembly controls the water flow, reducing water waste while preventing slippery aisles and facilitating passage. Powered by photovoltaic panels, it is energy-efficient and environmentally friendly, enabling fully automatic operation and reducing costs.

[0018] 2. In the present invention, during the movement of the spray mechanism, racks are provided on the slides above both sides of the aisle. When the spray mechanism is about to enter the aisle, the gear on the rotating wheel engages with the rack, and the rotating wheel rotates. During the rotation of the rotating wheel, the baffle provided on the inner ring of the rotating wheel blocks the avoidance hole on the valve ring, preventing water from entering the spray mechanism. This ensures that the spray mechanism no longer sprays when passing through the aisle, thereby effectively reducing the waste of water resources.

[0019] 3. When the spray mechanism of the present invention is about to enter the next experimental field, a rack is installed on the slide above the next experimental field. The gear of the rotating ring meshes with the rack, and the rotating ring rotates to open the baffle to open the avoidance hole, allowing water to flow and then spray. The position of the rack is designed according to the distribution of the experimental fields and the movement of the water flow control component, realizing automated control of the water flow.

[0020] 4. The number of avoidance holes in the present invention is set to correspond one-to-one with the baffle, so that the baffle can close and open the avoidance holes during the rotation of the rotating wheel. The angle at which the baffle needs to rotate when closing and opening the avoidance holes is controlled by the number of racks, which effectively improves the accuracy of opening and closing the baffle and reduces the waste of water resources.

[0021] 5. The present invention provides support for the mounting base during height adjustment by providing a support assembly, thereby preventing the increase in water tank weight during operation of the pump assembly, which would cause the gravity of the entire mounting base to act on the first screw, increasing the load on the first screw. This would not only damage the first screw, but also lead to poor stability of the entire device during height adjustment. By applying the change in gravity on the mounting base to the support assembly, the gravity is buffered by the elastic force of the spring, effectively improving the stability of the mounting base during height adjustment and extending the service life of the second screw.

[0022] 6. The present invention provides a pulling force to the spray mechanisms on both sides by providing a pulling force component. This not only maintains the stability of the spray mechanism during movement, but also effectively prevents the impact of the increased weight of the spray mechanisms on the second screw, thereby extending the service life of the second screw. The pull rods apply the gravity of the spray seats on both sides to the top of the mounting seat, which is then supported by the support component, ensuring the stability of the synchronous operation of the entire device. The provision of a chute improves the smoothness of the spray mechanism during movement and improves the efficiency of the spraying operation.

[0023] 7. The present invention can fully split the light source by setting a light-homogenizing plate, thereby ensuring that the crops under the photovoltaic panel have sufficient light intensity for photosynthesis. The light-homogenizing plate can change its internal structure to achieve the beam splitting function of different heights and widths. The structure of the light-homogenizing plate can be designed to any inclination angle, spacing and height, so that it can evenly disperse the area blocked by the photovoltaic panel, thereby minimizing the impact on plant growth.

[0035] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1 to 10As shown: A rice factory spraying device based on photovoltaic power generation, including a height adjustment mechanism 1, a linear drive mechanism 2, a spraying mechanism 3 and a water flow control component, the height adjustment mechanism 1 is fixedly arranged on both sides of the top of the greenhouse 8, and a photovoltaic panel 81 is arranged on the outside of the greenhouse 8; the linear drive mechanism 2 is installed on the height adjustment mechanism 1; the spraying mechanism 3 is installed on the linear drive mechanism 2; the water flow control component is installed at the connection between the spraying mechanism 3 and the water pipe; the height adjustment mechanism 1 controls the distance between the linear drive mechanism 2 and the ground; the linear drive mechanism 2 drives the spraying mechanism 3 to move, and then controls the spraying mechanism 3 to perform precise positioning; the spraying mechanism 3 controls the water flow through the water flow control component during the movement.

[0037] During actual use, the photovoltaic power generation-based rice factory spraying device absorbs light energy through the photovoltaic panels 81 on both sides of the top of the greenhouse 8, converts the light energy into electrical energy, and drives the height adjustment mechanism 1 through the electrical energy to control the height of the linear drive mechanism 2 above the ground. At the same time, the linear drive mechanism 2 is driven by the electrical energy to move the spraying mechanism 3 installed on the linear drive mechanism 2, so as to spray the rice inside the greenhouse 8. The spraying mechanism 3 is connected to the pump body assembly, and the pump body assembly supplies water or fertilizer to achieve rapid growth of the rice. The greenhouse 8 is provided with multiple experimental fields, each planted with rice. A linear drive mechanism 2 controls the spray mechanism 3 to spray each experimental field. The rice growth cycle and height of each experimental field may vary. The height adjustment mechanism 1 controls the height of the entire spray mechanism 3, allowing spraying to be tailored to experimental fields with rice of varying heights, improving the spraying effect and promoting rice growth. The height adjustment mechanism 1 is connected to a control system and can be pre-programmed based on the height of the rice in each experimental field to achieve automated rice spraying. To prevent water or fertilizer from being sprayed onto the aisle during movement, a water flow control assembly is provided to control the water flow. This reduces water waste, prevents slippery aisles, and facilitates passage for workers. The water flow control assembly can utilize a sensor. When the spray mechanism 3 is about to pass through the aisle, the sensor sends a signal to the control system, which controls the pump assembly to shut off the water flow. Power is supplied by photovoltaic panels 81, which are energy-efficient and environmentally friendly, enabling fully automatic operation and cost savings.

[0038] Reference Figures 8 to 10As shown: the water flow control assembly includes a valve ring 4, a rotating wheel 5 and a slide 6; the valve ring 4 is arranged at the connection point between the spray mechanism 3 and the water pipe; avoidance holes 41 are arranged at intervals on the valve ring 4; one end of the rotating wheel 5 is rotatably connected to the water pipe, and the other end is rotatably connected to the spray mechanism 3; baffles 51 are arranged at intervals on the inner ring of the rotating wheel 5, and the baffles 51 are fitted on the side wall of the valve ring 4; the slide 6 is fixedly mounted on the side wall of the linear drive mechanism 2; during the operation of the linear drive mechanism 2, the rotating wheel 5 moves horizontally along the slide 6; a gear 52 is provided on the rotating wheel 5; racks 61 are arranged at intervals on the slide 6; during the movement of the rotating wheel 5, the gear 52 engages with the rack 61.

[0039] When the linear drive mechanism 2 drives the spray mechanism 3 to move, the spray mechanism 3 moves together with the water flow control component. During the movement, the rotating wheel 5 moves along the direction set by the slide bar, and the pump body component flows water or fertilizer into the spray mechanism 3 through the avoidance hole 41 on the valve ring 4, and the spraying work is performed through the spray mechanism 3. During the movement of the spray mechanism 3, racks 61 are provided on the slides 6 above both sides of the aisle. When the spray mechanism 3 is about to enter the aisle, the gear 52 on the rotating wheel 5 engages with the rack 61, and the rotating wheel 5 rotates. During the rotation of the rotating wheel 5, the baffle 51 provided on the inner ring of the rotating wheel 5 blocks the avoidance hole 41 on the valve ring 4, preventing water from entering the spray mechanism 3. This prevents the spray mechanism 3 from spraying when it passes through the aisle, effectively reducing water waste. When the spray mechanism 3 is about to enter the next experimental field, a rack 61 is provided on the slide 6 above the next experimental field. The gear 52 of the rotating ring engages with the rack 61, and the rotating ring rotates to open the avoidance hole 41, allowing water to flow and then spray. The position of the rack 61 is designed according to the distribution of the experimental fields and the movement of the water flow control component to achieve automated control of the water flow. The number of avoidance holes 41 is set to correspond one-to-one with the baffles, so that when the rotating wheel 5 rotates, the baffles 51 can close and open the avoidance holes 41. The angle at which the baffles 51 need to rotate when closing and opening the avoidance holes 41 is controlled by the number of racks 61, effectively improving the accuracy of the opening and closing of the baffles 51 and reducing water waste. To prevent excessive water pressure from damaging components within the water flow control assembly when the baffles 51 block the avoidance holes 41, a sensor can be installed on the racks 61. When the rotating ring passes through the racks 61, the sensor sends a signal to the control system, which controls the opening and closing of the pump assembly, thereby reducing damage to the internal components of the water flow control assembly and extending its service life.

[0040] Reference Figure 2 and Figure 4 As shown: the height adjustment mechanism 1 includes a fixed seat 11, a first power device 12 and a first screw rod 13; the fixed seat 11 is fixedly arranged on both sides of the top of the greenhouse 8; the output end of the first power device 12 passes through the top of the fixed seat 11 and is connected to the first screw rod 13; the two sides of the linear drive mechanism 2 are fixedly installed on the first screw rod 13.

[0041] The first power device 12 is preferably a rotary motor. The first power device 12 drives the first screw 13 to rotate, causing the linear drive mechanism 2 to move up and down, thereby controlling the height of the spray mechanism 3 above the ground during operation. This allows for independent spraying of rice plants at different growth heights, better meeting the water requirements of rice plants at different growth stages, and helping to improve yield and quality. Simultaneously, adjusting the height of the spray mechanism 3 allows the water sprayed during the spraying operation to more accurately cover the target area, preventing water from being wasted in unnecessary areas. This further reduces water splashing and waste, thereby reducing water consumption and conserving water resources.

[0042] Reference Figure 4 and Figure 7 As shown: the linear drive mechanism 2 includes a mounting seat 21, a second power device 22 and a second screw rod 23; the mounting seat 21 is fixedly mounted on both sides of the first screw rod 13; the second power device 22 is arranged inside the mounting seat 21, and the output end of the second power device 22 is connected to the second screw rod 23; a slide 231 is provided on the second screw rod 23, and a water tank 232 is fixedly provided on the slide 231; the water tank 232 is connected to the spray mechanism 3.

[0043] The second power device 22 is preferably a rotary motor, which drives the second screw rod 23 to rotate, and the second screw rod 23 drives the slide 231 to move, wherein the water tank 232 is connected to the pump body assembly to realize mobile spraying.

[0044] Reference Figure 2 and Figure 3 As shown: spray mechanisms 3 are provided on both sides of the water tank 232.

[0045] By arranging the spraying mechanisms 3 on both sides of the water tank 232, the rice on both sides can be sprayed at the same time under the action of the linear drive mechanism 2, thereby effectively improving the efficiency of rice spraying.

[0046] Reference Figures 4 to 6As shown: the side wall of the height adjustment mechanism 1 is provided with a support assembly, and the support assembly includes a support seat 7, a support block 72 and a spring 73; the support seat 7 is arranged on the crossbeam plate at the top of the greenhouse 8; the support block 72 is arranged below the mounting seat 21; the support block 72 and the mounting seat 21 are an integral structure; a support groove 71 is provided inside the support seat 7; one end of the spring 73 is fixed to the bottom of the support groove 71, and the other end is fixedly connected to the bottom of the support block 72.

[0047] By providing a support assembly, the mounting base 21 is supported during the height adjustment process, preventing the weight of the water tank 232 from increasing during operation of the pump assembly, which would cause the gravity of the entire mounting base 21 to act on the first screw rod 13 and increase the load on the first screw rod 13. This would not only damage the first screw rod 13, but also lead to poor stability of the entire device during height adjustment. By applying the change in gravity on the mounting base 21 to the support assembly, the elastic force of the spring 73 buffers the gravity, effectively improving the stability of the mounting base 21 during height adjustment and extending the service life of the second screw rod 23.

[0048] Reference Figure 3 and Figure 8 As shown: the spray mechanism 3 includes a spray seat 31, which is connected to the water tank 232; a spray head 34 is provided below the spray seat 31; a tension component is provided on the top of the spray seat 31; the tension component provides tension to the spray seats 31 on both sides.

[0049] Several nozzles 34 may be positioned beneath the spray base 31. The specific number of nozzles 34 can be adjusted based on practical needs. Commonly used nozzles 34 include rotary nozzles 34 and Ferrari nozzles 34. Rotary nozzles 34 can rotate within a certain range, achieving a relatively uniform spraying effect, making them ideal for rice spraying. Ferrari nozzles 34 are more common, achieving a relatively uniform spraying effect within a certain range and are easy to use. They can be applied to different types of rice fields, offering a wide range of applications.

[0050] Reference Figure 3 As shown: the tension assembly includes a pull rod 32 and a sliding block 33; one end of the pull rod 32 on both sides is fixedly connected to the top of the spray seat 31 on both sides, and the other end is connected to the sliding block 33; a slide groove 211 is provided on the top of the mounting seat 21, and the sliding block 33 is slidably set in the slide groove 211.

[0051] By providing a tension component, a tensioning force can be applied to the spray mechanisms 3 on both sides. This not only maintains the stability of the spray mechanisms 3 during movement, but also effectively prevents the impact of the increased weight of the spray mechanisms 3 on the second screw 23, thereby extending the service life of the second screw 23. The pull rod 32 applies the gravity of the spray seats 31 on both sides to the top of the mounting seat 21, which is then supported by the support component, providing stability for the synchronous operation of the entire device. The provision of the slide 211 improves the smoothness of the movement of the spray mechanism 3 and improves the efficiency of the spraying operation.

[0052] Reference Figure 1 As shown: the photovoltaic panels 81 are arranged at intervals on both sides of the top of the greenhouse 8; a light-diffusing plate 82 is arranged between adjacent photovoltaic panels 81; the light-diffusing plate 82 is used to disperse sunlight.

[0053] By setting up the light-homogenizing plate 82, the light source can be fully split, which can ensure that the crops under the photovoltaic panel 81 have sufficient light intensity for photosynthesis. The light-homogenizing plate 82 can change its internal structure to achieve the beam splitting function of different heights and widths. The structure of the light-homogenizing plate 82 can be designed to any inclination angle, spacing and height, so that it can evenly disperse the area blocked by the photovoltaic panel 81, thereby minimizing the impact on plant growth.

[0054] Reference Figure 3 As shown: the slide plate 6 is fixedly arranged on the side wall of the mounting seat 21.

[0055] The above embodiments merely represent one or more embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
