Description

Technical Field

[0001] The present invention relates to the technical field of automated greenhouse cleaning, and in particular to automated cleaning equipment and methods for agricultural greenhouses. Background Art

[0002] A glass greenhouse is a type of greenhouse that uses glass as the primary light-transmitting covering material. It has a long service life and is suitable for a variety of regions and climates. It is divided into different types of greenhouses to grow different plants. To ensure that sunlight can pass through the glass outer wall smoothly, the greenhouse roof needs to be cleaned regularly.

[0003] The Chinese patent publication number CN 118305109 A discloses a greenhouse roof cleaning device. While the mobile platform is constantly moving, the driving motor drives the cleaning brush to rotate, and the water supply component continuously sprays cleaning water toward the sloping roof. Combined with the friction of the cleaning brush, the greenhouse roof can be cleaned to ensure that the interior of the greenhouse can smoothly obtain external sunlight. When the mobile platform moves to the edge of the greenhouse, it will return to the original path and clean the greenhouse roof again. At the same time, since the cleaning position is in the depression of the two sloping roofs, the sewage remaining during the cleaning process will be concentrated in the center under the action of gravity. When the cleaning platform moves back, the bottom of the cleaning platform will push the sewage back. Through this arrangement, not only the effect of effectively cleaning the dirt on the top of the greenhouse is achieved, but also no sewage will remain. Water is used on the top surface of the greenhouse, which is more effective than traditional cleaning methods. After cleaning the two sloping roofs, the cleaning table returns to the mobile table, and the mobile device moves the cleaning table to the other side of the sloping roof for the next cleaning. The problem of multiple back and forth cleaning is that the equipment needs to be cleaned. In the process of the equipment moving forward, the accumulation of stains washed by rain and snow will affect the movement of the equipment. At the same time, if bad weather occurs during operation, the equipment will not avoid it by itself, and it will continue to work, which can easily lead to danger. In addition, traditional equipment cannot be adapted to a variety of greenhouses. For example, if the angle of the greenhouse top is not suitable, there will be a large space that cannot be cleaned. Therefore, the present application provides an automated cleaning equipment and method for agricultural greenhouses to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automated cleaning device and method for agricultural greenhouses to solve the problem that existing equipment cannot adapt to a variety of greenhouses. For example, when there is an inappropriate angle on the top of the greenhouse, there will be a large space that cannot be cleaned properly and multiple cleanings are required. In addition, during the forward movement of the equipment, the accumulation of stains washed by rain and snow will affect the movement of the equipment. At the same time, the equipment will not automatically avoid bad weather during operation.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] An automated cleaning device for agricultural greenhouses, comprising an equipment platform and a brush roller group. On both sides of the equipment platform, there are lateral supports. At the lower part of the lateral supports, a driving group is installed. On the upper surface of the equipment platform, a control device is installed. On one side of the upper surface of the equipment platform, there is a water tank. On the other side of the upper surface of the equipment platform, there is a sewage tank. On one side of the sewage tank, a sludge pump is installed. On the lower surface of the equipment platform, a water supply pipe assembly is installed. At the lower part of the equipment platform, a hydraulic base is installed. Inside the hydraulic base, a hydraulic device is installed. At the lower part of the hydraulic device, a lifting seat is installed. On the upper surface of the equipment platform, there is a storage battery; The brush roller group includes a brush roller support. Inside the brush roller support, a following seat is rotatably connected. On one side of the following seat, there is a telescopic strut, a water spray pipe, and a brush roller installed in sequence from top to bottom. One end of the telescopic strut is installed with a transfer seat. Inside the transfer seat, a lifting seat is rotatably connected. On one side of the brush roller support, a brush roller motor is installed. The brush roller motor passes through the brush roller support and is connected to the brush roller; The driving group includes a moving support. On the upper surface of the moving support, there is a motor platform. Inside the motor platform, a driving motor is installed. One end of the driving motor is sleeved with a driving belt. Inside the driving belt, a moving wheel is sleeved. At the lower part of the moving support, a moving wheel is rotatably connected.

[0007] Optionally, a water supply pipe assembly is installed at the lower part of the equipment platform. The water supply pipe assembly includes a water supply pipe support. Inside the water supply pipe support, a spring is clamped. Inside the water supply pipe support, a water pipe shaft is slidably connected. Inside the water pipe shaft, a water pipe is wound. The water pipe is connected to the water tank. The lower part of the spring is installed with a water pipe shaft.

[0008] Optionally, a fan group is installed on the lower surfaces of both sides of the equipment platform. The fan group includes a fan support. Inside the fan support, a high-power fan is installed through a fan rotating shaft.

[0009] Optionally, a wind direction assembly is installed on the upper surface of the equipment platform. The wind direction assembly includes a rotating base. On the upper part of the rotating base, a generator support is installed. Inside the generator support, a generator and wind blades are installed. On one side of the generator support, there is a wind deflector. The generator is electrically connected to the control device.

[0010] Optionally, an adjustment frame is installed at the lower part of the adapter base. The lower part of the adjustment frame is hollow. A cleaning motor bracket is fixedly connected to the lower part of the adjustment frame. The cleaning motor bracket is connected to a cleaning plate through three support rods at the lower part. Two cleaning wheels are rotatably connected to the lower part of the cleaning plate. A cleaning motor is installed on the upper part of the cleaning wheel. The cleaning motor is installed inside the cleaning motor bracket. Pulley wheels are arranged on the upper parts of the two cleaning wheels and are connected by a cleaning belt. One of the pulley wheels is connected to the cleaning motor.

[0011] Optionally, a plurality of electric control water pumps are installed on one side of the water tank. The electric control water pumps are connected to a water spraying pipe. A sludge pipe is connected to the lower part of the sludge pump. The sludge pipe is located inside the lateral support bracket.

[0012] Optionally, an auxiliary wheel bracket is arranged on one side of the lateral support bracket. An auxiliary wheel is installed inside the auxiliary wheel bracket. A sludge suction port is arranged at the lower part of the auxiliary wheel bracket. The sludge suction port is connected to the sludge pump through a sludge pipe.

[0013] Optionally, small nozzles are installed inside one end of the drive group. The number of the small nozzles is two and they are arranged in parallel. The nozzle of one of the small nozzles faces forward, and the nozzle of the other small nozzle faces the moving wheel. The small nozzles are connected to one of the electric control water pumps on one side of the water tank through a water pipe. A booster water pump is installed in the middle of the water pipe.

[0014] Optionally, a bolt penetrates through the inside of the adjustment frame. The upper part of the bolt is connected to the adapter base and the lower part is connected to the cleaning motor bracket. The angle of the cleaning plate can be adjusted by the bolt.

[0015] A method for an automatic cleaning device for an agricultural greenhouse includes the following steps:

[0016] Step 1: Install the device on the top of the greenhouse. For a greenhouse with a double-slope symmetric appearance style, adjust according to the situation of the greenhouse top. The lifting seat can be lifted by a hydraulic device, which drives the telescopic support rod to extend and makes one side of the brush roller group lift upward, so as to better adapt to the angle of the greenhouse top. For example, for a flat-top greenhouse, the hydraulic device can be pressed down, and the bolts inside the adjustment frame are adjusted according to the situation of the greenhouse top, so that the angle of the cleaning plate deviates and fits the greenhouse top to increase the cleaning range. When using a flat-top greenhouse, loosen the bolts inside the cleaning plate adjustment frame, adjust the angle of the cleaning plate and then lock the bolts, and place the cleaning plate in the middle of the two brush rollers.

[0017] Step 2: The drive motor drives the moving wheel to rotate by driving a drive belt, driving the device to move. By installing small nozzles at the front end of the drive group, the sludge at the advancing position of the moving wheel can be flushed, and the sludge attached to the moving wheel can be cleaned to avoid the situation that the sludge causes the device to get stuck and the device to jolt.

[0018] Step 3: The auxiliary wheels at the rear end can make the device move forward more smoothly. The sludge suction port provided at the lower part of the auxiliary wheel bracket is connected to the sludge pump through the sludge pipe installed inside the lateral bracket and the auxiliary wheel bracket, and sucks the sewage washed out by this device and the sewage flushed out by the small nozzles at the front end of the drive group.

[0019] Step 4: By adjusting the fan shaft in the fan group, the angle of the high-power fan is adjusted to blow the residual water stains on the surface of the greenhouse after cleaning to the drainage grooves on both sides, reducing the problem of reduced light transmittance caused by scale formed after the water stains dry on the surface of the greenhouse.

[0020] Step 5: Check the rotation of the wind direction component. When the device is in operation and the wind force increases, the generator generates electricity through the rotation of the wind blades. When the generated electricity exceeds the set threshold, the device will cut off the power supply and drive the drive group through the electricity in the battery to reset this device to the starting position.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] In the above solution, the hydraulic device can be used to lift the lifting seat, which drives the telescopic support rod to extend and raises one side of the brush roller group, so as to better adapt to the angles of different greenhouse tops. For example, for a flat-top greenhouse, the hydraulic device can be pressed down to make the brush roller group parallel to the ground to clean the greenhouse top. When the brush roller group is lifted, there will be a large area in the middle that cannot be swept by the brush roller. At this time, the bolts inside the adjusting frame can be adjusted to make the angle of the cleaning plate deviate and fit the greenhouse top to increase the cleaning range of this device. The cleaning motor drives the cleaning wheel to rotate to clean the bottom above the cleaning plate. Pulley wheels are provided above the cleaning wheels. When the cleaning motor drives one cleaning wheel to rotate, the other cleaning wheel will rotate together. When used in a flat-top greenhouse, loosen the bolts inside the cleaning plate adjusting frame to adjust the angle of the cleaning plate and then lock the bolts. It should be noted that the cleaning plate is located in the middle of the two brush rollers and will not block the downward movement of the brush rollers.

[0023] By setting up the drive group, the device can move forward and backward. In the drive group, the drive motor is raised through the motor platform, reducing the contact of the drive motor with the sewage splashed during cleaning. Different from traditional equipment that places the motor at the top of the equipment and uses a transmission rod for driving, the motor is still located slightly below the center point of the equipment, thus reducing the situation of unstable equipment center of gravity. And driving through the drive belt is easier to maintain compared to the transmission rod. Pulley wheels are installed at the positions where the drive motor and the moving wheels are connected by the drive belt. A small nozzle is installed at the front end of the drive group, which can wash the sludge at the advancing position of the moving wheels and clean the sludge attached to the moving wheels to avoid the situation of equipment jamming and bumping caused by sludge. It should be noted that drainage grooves are installed on both sides of the top of the greenhouse with a double-slope symmetric appearance style. The moving wheels will move in the drainage grooves and wash and clean the drainage grooves. When traditional equipment cleans the greenhouse, it only cleans the stains on the surface of the greenhouse. When the stains flow downward, it is easy to cause sludge accumulation in the drainage grooves, and the sludge will affect the movement of the equipment during the next cleaning.

[0024] By setting up a sludge suction port, it is connected to a sludge pump through a sludge pipe installed inside the lateral support and the auxiliary wheel support, sucking the sewage cleaned by this device and the sewage flushed out by the small nozzle at the front end of the drive group, reducing the sludge accumulation in the drainage grooves and reducing the situation of water seepage in the greenhouse during rainy and snowy weather due to untimely drainage.

[0044] As Figures 1 to 5As shown in the figure, an embodiment of the present invention provides an automatic cleaning device for an agricultural greenhouse, which includes a device platform 1 and a roller brush group 2. Side brackets 3 are provided on both sides of the device platform 1, and a driving group 4 is installed at the lower part of the side brackets 3. The driving group 4 includes a moving bracket 401. A motor platform 402 is provided on the upper surface of the moving bracket 401. A driving motor 403 is installed inside the motor platform 402. One end of the driving motor 403 is sleeved with a driving belt 404. A moving wheel 405 is sleeved inside the driving belt 404. The moving wheel 405 is rotatably connected to the lower part of the moving bracket 401. A control device 5 is installed on the upper surface of the device platform 1. A water tank 6 is provided on one side of the upper surface of the device platform 1. A plurality of electric control water pumps 22 are installed on one side of the water tank 6. The electric control water pumps 22 are connected to a water spray pipe 204. The lower part of a sludge pump 8 is connected to a sludge pipe, and the sludge pipe is located inside the side bracket 3. A sewage tank 7 is provided on the other side of the upper surface of the device platform 1. A sludge pump 8 is installed on one side of the sewage tank 7. A water supply pipe assembly 9 is installed on the lower surface of the device platform 1. A water supply pipe assembly 9 is installed at the lower part of the device platform 1. The water supply pipe assembly 9 includes a water supply pipe bracket 901. A spring 902 is clamped inside the water supply pipe bracket 901. A water pipe shaft 903 is slidably connected inside the water supply pipe bracket 901. A water pipe is wound inside the water pipe shaft 903, and the water pipe is connected to the water tank 6. The spring 902 is installed at the lower part of the water pipe shaft 903. A hydraulic base 10 is installed at the lower part of the device platform 1. A hydraulic device 11 is installed inside the hydraulic base 10. A lifting seat 12 is installed at the lower part of the hydraulic device 11. The roller brush group 2 includes a roller brush bracket 201. A following seat 202 is rotatably connected inside the roller brush bracket 201. A telescopic support rod 203, a water spray pipe 204 and a roller brush 205 are sequentially installed on one side of the following seat 202 from top to bottom. One end of the telescopic support rod 203 is installed with a transfer seat 206. The lifting seat 12 is rotatably connected inside the transfer seat 206. A roller brush motor 207 is installed on one side of the roller brush bracket 201. The roller brush motor 207 passes through the roller brush bracket 201 and is connected to the roller brush 205. An adjusting frame 16 is installed at the lower part of the transfer seat 206. A bolt is threaded through the inside of the adjusting frame 16. The upper part is connected to the transfer seat 206 and the lower part is connected to a cleaning motor bracket 17. The angle of the cleaning plate 19 can be adjusted by the bolt. The lower part of the adjusting frame 16 is hollow. The lower part of the adjusting frame 16 is fixedly connected to a cleaning motor bracket 17. The cleaning motor bracket 17 is connected to a cleaning plate 19 through three lower struts 18. Two cleaning wheels 20 are rotatably connected to the lower part of the cleaning plate 19. A cleaning motor 21 is installed at the upper part of the cleaning wheel 20. The cleaning motor 21 is installed inside the cleaning motor bracket 17. Pulley wheels are provided at the upper parts of the two cleaning wheels 20 and are connected by a cleaning belt. One of the pulley wheels is connected to the cleaning motor 21.

[0045] The device is connected to the outside through a water intake pipe. When the device moves, it drives the rotation of the water pipe shaft 903. When the water pipe shaft 903 rotates too fast, it will squeeze the spring 902, causing the water pipe shaft 903 to bounce up and down in the water supply pipe bracket 901, reducing the situation of water pipe jamming. The electric control water pump 22 on one side of the water tank 6 is connected to the water spray pipe 204. When the device moves, the electric control water pump 22 pumps out the water source and sprays it on the surface of the greenhouse through the water spray pipe 204, and the rotary brush 205 brushes the surface of the greenhouse. In this application, two groups of rotary brushes 205 are used to increase the brushing area and reduce the residue of stubborn stains.

[0046] The lifting seat 12 can be lifted by the hydraulic device 11, which drives the telescopic support rod 203 to extend and raises one side of the rotary brush group 2, so as to better adapt to the angles of different greenhouse tops. For example, for a flat-top greenhouse, the hydraulic device 11 can be pressed down to make the rotary brush group 2 parallel to the ground to clean the greenhouse top. When the rotary brush group 2 is lifted, there will be a large area in the middle that cannot be swept by the rotary brush 205. At this time, the bolts inside the adjusting frame 16 can be adjusted to make the angle of the cleaning plate 19 deviate and fit the greenhouse top to increase the cleaning range of this device. The cleaning motor 21 drives the cleaning wheel 20 to rotate to clean the bottom above the cleaning plate 19. Pulley wheels are provided on the upper part of the cleaning wheel 20. When the cleaning motor 21 drives one cleaning wheel 20 to rotate, the other cleaning wheel 20 will rotate together. When used in a flat-top greenhouse, loosen the bolts inside the adjusting frame 16 of the cleaning plate 19, adjust the angle of the cleaning plate 19, and then lock the bolts. It should be noted that the cleaning plate 19 is located in the middle of the two rotary brushes 205 and will not block the downward movement of the rotary brush 205.

[0047] Such as Figures 6 to 10As shown in the figure, in this embodiment, the driving group 4 includes a moving bracket 401. The upper surface of the moving bracket 401 is provided with a motor platform 402. A driving motor 403 is installed inside the motor platform 402. One end of the driving motor 403 is sleeved with a driving belt 404. A moving wheel 405 is sleeved inside the driving belt 404. The lower part of the moving bracket 401 is rotatably connected to the moving wheel 405. One end inside the driving group 4 is provided with a small nozzle 25. The number of small nozzles 25 is two and they are arranged in parallel. The nozzle position of one small nozzle 25 faces forward, and the nozzle of the other small nozzle 25 faces the moving wheel 405. The small nozzle 25 is connected to one of the electric control water pumps 22 on one side of the water tank 6 through a water pipe 26. A booster water pump 27 is installed in the middle of the water pipe 26. The lower surfaces on both sides of the equipment platform 1 are installed with a fan group 14. The fan group 14 includes a fan bracket 141. A high-power fan 143 is installed inside the fan bracket 141 through a fan rotating shaft 142. The upper surface of the equipment platform 1 is installed with a wind direction assembly 15. The wind direction assembly 15 includes a rotating base 151. The upper part of the rotating base 151 is installed with a generator bracket 152. A generator 153 and a wind blade 154 are installed inside the generator bracket 152. A wind guide plate is provided on one side of the generator bracket 152. The generator 153 is electrically connected to the control device 5. A plurality of electric control water pumps 22 are installed on one side of the water tank 6. The electric control water pump 22 is connected to a water spray pipe 204. The lower part of the sludge pump 8 is connected with a sludge pipe. The sludge pipe is located inside the lateral bracket 3. An auxiliary wheel bracket 23 is provided on one side of the lateral bracket 3. An auxiliary wheel 24 is installed inside the auxiliary wheel bracket 23. A sludge suction port is provided at the lower part of the auxiliary wheel bracket 23. The sludge suction port is connected to the sludge pump 8 through a sludge pipe.

[0048] The device can move forward and backward through the drive group 4. In the drive group 4, the drive motor 403 is lifted by the motor platform 402, so that the drive motor 403 is less likely to come into contact with the sewage splashed during cleaning. Different from traditional equipment that places the motor on the top of the equipment and uses a transmission rod for driving, the motor is still located at a position slightly below the center point of the equipment, thus reducing the situation of unstable equipment center of gravity. And the transmission through the drive belt 404 is easier to maintain than the transmission rod. Belt pulleys are installed at the positions where the drive motor 403 and the moving wheel 405 are connected to the drive belt 404. A small nozzle 25 is installed at the front end of the drive group 4, which can wash the sludge at the advancing position of the moving wheel 405 and clean the sludge attached to the moving wheel 405 to avoid the situation of equipment jamming and equipment bumping caused by sludge. It should be noted that drainage grooves are installed on both sides of the top of the greenhouse with a double-slope symmetric appearance style. The moving wheel 405 will move in the drainage grooves and wash and clean the drainage grooves. When traditional equipment cleans the greenhouse, it only cleans the stains on the surface of the greenhouse. When the stains flow downward, it is very easy to cause sludge accumulation in the drainage grooves. The sludge will affect the movement of the equipment during the next cleaning.

[0049] The equipment can move forward more smoothly through the auxiliary wheels at the rear end of the device. A sludge suction port is installed in the auxiliary wheel bracket 23. The sludge suction port is connected to the sludge pump 8 through the sludge pipe installed inside the lateral bracket 3 and the auxiliary wheel bracket 23, sucking the sewage cleaned by the device and the sewage flushed out by the small nozzle at the front end of the drive group 4, reducing the sludge accumulation in the drainage grooves and reducing the situation of water seepage in the greenhouse during rainy and snowy weather due to untimely drainage.

[0050] By adjusting the fan shaft 142 in the fan group 14 and adjusting the angle of the high-power fan 143, the residual water stains on the surface of the cleaned greenhouse are blown into the drainage grooves on both sides, reducing the problem of reduced light transmittance caused by scale formed after the water stains dry on the surface of the greenhouse, and also reducing the problem that traditional equipment needs to clean back and forth multiple times due to residual sewage during the cleaning process.

[0051] Through the installation of the wind direction component 15, during the use of the device, the generator 153 generates electricity driven by the wind blade 154 and stores it in the storage battery 13. For example, during the operation of the device, when the wind force increases and the generator 153 generates electricity by rotating the wind blade 154, and the generated electricity exceeds the set threshold, the threshold is set that when the rated wind speed is 120% - 150% in the over-limit state and lasts for 10 seconds, the threshold reference formula is V threshold =k⋅V rated (k belongs to [1.2, 1.5]), where V ratedIt can be set according to local conditions by referring to the IEC 61400-25 standard. After the threshold is triggered, the device will cut off the power supply, and the driving group 4 will be driven by the power in the storage battery to reset the device to the starting position, reducing the hazards and equipment damage that may occur due to bad weather.

[0052] The working principle of the technical solution provided by the present invention is as follows:

[0053] Install the device on the top of the greenhouse, and adjust the appearance style of the double-slope symmetric greenhouse according to the situation of the greenhouse top. The hydraulic device 11 can lift the lifting seat 12, which drives the telescopic support rod 203 to extend, and raises one side of the brush roller group 2, so as to better adapt to the angle of the greenhouse top. For example, for a flat-top greenhouse, the hydraulic device 11 can be pressed down, and the bolts inside the adjusting frame 16 can be adjusted according to the situation of the greenhouse top, so that the angle of the cleaning plate 19 is offset to fit the greenhouse top to increase the cleaning range. When using a flat-top greenhouse, loosen the bolts inside the adjusting frame 16 of the cleaning plate 19 to adjust the angle of the cleaning plate 19 and then lock the bolts, and place the cleaning plate 19 in the middle of the two brush rollers 205. During the movement of the device, the driving group 4 can make the device move forward and backward. Turn on the electric control water pump 22 to make the small nozzles 25 spray water, which can wash the sludge at the advancing position of the moving wheels 405. Before using the device, it is necessary to adjust the fan shaft 142 in the fan group 14, adjust the angle of the high-power fan 143, blow the remaining water stains on the surface of the cleaned greenhouse to the drainage grooves on both sides, and check the rotation of the wind direction component 15. The generator 153 generates electricity driven by the wind blades 154. In case of bad weather, the device will cut off the power supply, and the driving group 4 will be driven by the power in the storage battery 13 to reset the device to the starting position, which will protect the safety of the device.
