Description

Technical Field

[0001] The present invention relates to the technical field of greenhouse automatic cleaning, and in particular to an automatic cleaning device and method for agricultural greenhouses. Background Art

[0002] Glass greenhouse is a type of greenhouse that uses glass as the main 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 greenhouses for growing different plants. In order to ensure that sunlight can pass through the glass outer wall smoothly, the top of the greenhouse needs to be cleaned regularly.

[0003] The Chinese patent with publication number CN 118305109 A discloses a greenhouse top cleaning device. During the continuous movement of the mobile platform, the driving motor drives the cleaning brush to rotate, and the water supply component continuously sprays cleaning water toward the sloping roof. With the friction of the cleaning brush, the top of the greenhouse can be cleaned to ensure that the inside 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 top of the greenhouse again. At the same time, since the cleaning position is in the concave part of the two sloping roofs, the residual sewage 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 residual dirt will be left. Water is 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, 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 may easily lead to danger. In addition, traditional equipment cannot be adapted to a variety of greenhouses. For example, if the top of a greenhouse is not suitable for the angle, there will be a large space that cannot be cleaned properly. Therefore, the present application provides an automated cleaning device 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 the existing equipment cannot be adapted to a variety of greenhouses. For example, when there is a greenhouse top with an inappropriate angle, 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, stains washed by rain and snow will accumulate and affect the movement of the equipment.

[0009] Optionally, an adjustment frame is installed at the lower part of the adapter seat, and 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 the cleaning plate through three support rods at the lower part. The lower part of the cleaning plate is rotatably connected to two cleaning wheels. A cleaning motor is installed at the upper part of the cleaning wheel. The cleaning motor is installed inside the cleaning motor bracket.

[0012] Optionally, a small nozzle is installed inside one end of the driving group, and the number of the small nozzles is two and they are arranged in parallel, the nozzle of one of the small nozzles is facing forward, and the nozzle of the other small nozzle is facing the moving wheel.

[0013] Optionally, bolts are passed through the internal threads of the adjustment frame, the upper part is connected to the adapter seat and the lower part is connected to the cleaning motor bracket, and the angle of the cleaning plate can be adjusted by the bolts.

[0014] A method for automated cleaning equipment for agricultural greenhouses, comprising the following steps: Step 1. Install the equipment on the top of the greenhouse and adjust it according to the situation of the top of the greenhouse. For a greenhouse with a double-slope symmetrical appearance, the lifting seat can be pulled up by the hydraulic device, so that it can drive the telescopic support rod to extend and lift one side of the roller brush group upward to better adapt to the angle of the top of the greenhouse. For example, for a flat-top greenhouse, the hydraulic device can be pressed down, and the bolts inside the adjustment frame can be adjusted according to the situation of the top of the greenhouse so that the angle of the cleaning plate is offset and fits the top of the greenhouse 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, then tighten the bolts and place the cleaning plate in the middle of the two roller brushes.

[0015] Step 2: The driving motor drives the driving belt to rotate the moving wheel, driving the equipment to move. A small nozzle is installed at the front end of the driving group to flush the sludge at the forward position of the moving wheel, and the sludge attached to the moving wheel is cleaned to avoid the sludge causing the equipment to jam and shake. Step 3: The auxiliary wheels at the rear end can make the equipment move forward more smoothly. The sludge suction port provided at the bottom of the auxiliary wheel bracket is connected to the sludge pump through the lateral bracket and the sludge pipe installed inside the auxiliary wheel bracket to suck the sewage cleaned by the device and the sewage flushed out by the small nozzle at the front end of the driving group.

[0016] Step 4: By adjusting the fan shaft in the fan unit and the angle of the high-power fan, the residual water stains on the surface of the greenhouse after cleaning are blown to the drainage grooves on both sides to reduce the problem of reduced light transmittance caused by scale after the water stains dry on the surface of the greenhouse; Step 5. Check the rotation of the wind direction component. When the equipment is in operation and the wind force becomes stronger, the generator generates electricity through the rotation of the wind blades. When the power generation exceeds the set threshold, the equipment will be powered off and the drive group will be driven by the power in the battery to reset the device to the starting position.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, a hydraulic device can be set to pull up the lifting seat, so that it drives the telescopic support rod to extend and one side of the roller brush group to be lifted upward, so as to better adapt to the angles of different greenhouse tops. For example, in a flat-top greenhouse, the hydraulic device can be pressed down to make the roller brush group parallel to the ground to clean the top of the greenhouse. When the roller brush group is lifted, a large area will appear in the middle part that cannot be cleaned by the roller brush. At this time, the bolts inside the adjustment frame can be adjusted to make the angle of the cleaning plate offset and fit the top of the greenhouse to increase the cleaning range of the device. The cleaning wheel is driven by the cleaning motor to rotate on the upper part of the cleaning plate to clean the bottom. A pulley is provided on the upper part of the cleaning wheel. When the cleaning motor drives one cleaning wheel to rotate, the other cleaning wheel will rotate together. When the flat-top greenhouse is used, the bolts inside the cleaning plate adjustment frame are loosened to adjust the angle of the cleaning plate and then the bolts are locked. It is worth noting that the cleaning plate is located in the middle of the two roller brushes and will not cause any obstruction to the downward movement of the roller brush.

[0018] The device can move forward and backward by setting a drive group. The drive motor is raised by the motor platform in the drive group to reduce the contact of the drive motor with the sewage splashed during cleaning. Unlike the traditional equipment that places the motor on the top of the equipment and drives it with a transmission rod, the motor is still located below the center point of the equipment, thereby reducing the instability of the center of gravity of the equipment. Compared with the transmission rod, the transmission through the drive belt is better maintained. Pulleys are installed at the positions where the drive motor and the moving wheel are connected to the drive belt. A small nozzle is installed at the front end of the drive group to flush the sludge at the forward position of the moving wheel and the sludge attached to the moving wheel to avoid the sludge causing the equipment to jam and bump. It is worth noting that drainage grooves are installed on both sides of the top of the greenhouse with a double-slope symmetrical appearance. The moving wheel will move in the drainage groove and flush and clean the drainage groove. When cleaning the greenhouse, the traditional equipment only cleans the stains on the surface of the greenhouse. When the stains flow downward, it is also very easy to cause sludge accumulation in the drainage groove. The sludge will affect the movement of the equipment when cleaning next time.

[0019] By setting a sludge suction port and connecting it to the sludge pump through the sludge pipe installed inside the side bracket and the auxiliary wheel bracket, the sewage cleaned by the device and the sewage flushed out by the small nozzle at the front end of the driving group are sucked out, thereby reducing the accumulation of sludge in the drainage ditch and reducing the seepage of the greenhouse due to untimely drainage in rainy and snowy weather.

The water supply pipe assembly 9 includes a water supply pipe bracket 901, and a spring 902 is clamped inside the water supply pipe bracket 901. A water pipe shaft 903 is slidably connected to the inside of the water supply pipe bracket 901, and a water pipe is wound inside the water pipe shaft 903. The water pipe and the water tank 6 are connected to each other, and the water pipe shaft 90 is installed at the lower part of the spring 902. 3. A hydraulic base 10 is installed at the lower part of the equipment 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, a roller brush group 2 includes a roller brush bracket 201, the roller brush bracket 201 is internally rotatably connected to a follower seat 202, one side of the follower seat 202 is provided with a telescopic support rod 203, a water spray pipe 204 and a roller brush 205 installed in sequence from top to bottom, an adapter seat 206 is installed at one end of the telescopic support rod 203, the adapter seat 206 is internally rotatably connected to the lifting seat 12, a roller brush motor 207 is installed at one side of the roller brush bracket 201, the roller brush motor 207 penetrates the roller brush bracket 201 and is connected to the roller brush 205, and an adjusting The section frame 16, the internal thread of the adjustment frame 16 is penetrated by bolts, the upper part is connected to the adapter 206, and the lower part is connected to the cleaning motor bracket 17, the angle of the cleaning plate 19 can be adjusted by bolts, the lower part of the adjustment frame 16 is hollow, the lower part of the adjustment frame 16 is fixedly connected to the cleaning motor bracket 17, the cleaning motor bracket 17 is connected to the cleaning plate 19 through the three support rods 18 at the lower part, the lower part of the cleaning plate 19 is rotatably connected to two cleaning wheels 20, the upper part of the cleaning wheel 20 is installed with a cleaning motor 21, the cleaning motor 21 is installed inside the cleaning motor bracket 17, the upper parts of the two cleaning wheels 20 are provided with pulleys, which are connected by a cleaning belt, and one of the pulleys is connected to the cleaning motor 21.

[0030] By pulling the water pipe to connect with the outside world, the water pipe shaft 903 will be driven to rotate when the equipment moves. If the water pipe shaft 903 rotates too fast, the spring 902 will be squeezed, causing the water pipe shaft 903 to bounce up and down in the water supply pipe bracket 901, reducing the jam of the water pipe. The electric water pump 22 on one side of the water tank 6 is connected to the water spray pipe 204. When the equipment moves, the electric water pump 22 draws water from the source through the water spray pipe 204 to spray the surface of the greenhouse, and the roller brush 205 scrubs the surface of the greenhouse. In this application, two sets of roller brushes 205 are used to increase the scrubbing area and reduce the residue of stubborn stains.

[0031] The lifting seat 12 can be pulled up by the hydraulic device 11, so that it drives the telescopic support rod 203 to extend, and one side of the roller brush group 2 is lifted upward, so as to better adapt to the angles of different greenhouse tops. For example, in a flat-top greenhouse, the hydraulic device 11 can be pressed down to make the roller brush group 2 parallel to the ground to clean the top of the greenhouse. When the roller brush group 2 is lifted, a large area of ​​the middle part will appear where the roller brush 205 cannot clean. At this time, the bolts inside the adjusting frame 16 can be adjusted to make the angle of the cleaning plate 19 offset and fit the top of the greenhouse to increase the height of the device. In the cleaning range, the cleaning wheel 20 is driven to rotate by the cleaning motor 21 on the upper part of the cleaning plate 19 to clean the bottom. A pulley is 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-roof greenhouse, the bolts inside the cleaning plate 19 adjustment frame 16 are loosened to adjust the angle of the cleaning plate 19 and then the bolts are tightened. It is worth noting that the cleaning plate 19 is located in the middle of the two roller brushes 205 and will not cause any obstruction to the roller brush 205 when it moves downward.

[0032] like Figures 6 to 10As shown, in this embodiment, the driving group 4 includes a mobile bracket 401, and a motor platform 402 is provided on the upper surface of the mobile bracket 401. A driving motor 403 is installed inside the motor platform 402, and a driving belt 404 is sleeved on one end of the driving motor 403. A moving wheel 405 is sleeved on the inside of the driving belt 404. The lower part of the mobile bracket 401 is rotatably connected to the moving wheel 405. A small nozzle 25 is installed inside one end of the driving group 4. 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-controlled 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. Fan groups 14 are installed on the lower surfaces of both sides of the equipment platform 1. The fan group 14 includes a fan bracket 14. 1. A high-power fan 143 is installed inside the fan bracket 141 through the fan shaft 142. A wind direction assembly 15 is installed on the upper surface of the equipment platform 1. The wind direction assembly 15 includes a rotating base 151. A generator bracket 152 is installed on the upper part of the rotating base 151. A generator 153 and a fan 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 and the control device 5 are electrically connected to each other. A plurality of electrically controlled water pumps 22 are installed on one side of the water tank 6. The electrically controlled water pumps 22 are connected to the water spray pipe 204. A sludge pipe is connected to the lower part of the sludge pump 8. 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 the sludge pipe.

[0033] The device can be moved forward and backward by the driving group 4. The driving motor 403 is raised by the motor platform 402 in the driving group 4, so that the driving motor 403 is less likely to contact the sewage splashed during cleaning. Unlike the traditional equipment that places the motor on the top of the equipment and drives it with a transmission rod, the motor is still located at a position slightly below the center point of the equipment, thereby reducing the instability of the center of gravity of the equipment. Compared with the transmission rod, the transmission is better maintained by the driving belt 404. Pulleys are installed at the position where the driving motor 403 and the moving wheel 405 are connected to the driving belt 404. A small The nozzle 25 can flush the sludge at the forward position of the moving wheel 405, and clean the sludge attached to the moving wheel 405 to avoid the situation where the sludge causes the equipment to jam and the equipment to bump. It is worth noting that drainage grooves are installed on both sides of the top of the greenhouse with a double-slope symmetrical appearance. The moving wheel 405 will move in the drainage grooves and flush and clean the drainage grooves. When cleaning the greenhouse, traditional equipment only cleans the stains on the surface of the greenhouse. When the stains flow downward, it is also very easy to cause sludge accumulation in the drainage grooves. The sludge will affect the movement of the equipment during the next cleaning.

[0034] The auxiliary wheels at the rear end of the device can make the equipment move forward more smoothly. 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 lateral bracket 3 and the sludge pipe installed inside the auxiliary wheel bracket 23. The sewage cleaned by the device and the sewage flushed out by the small nozzle at the front end of the driving group 4 are sucked, thereby reducing the accumulation of sludge in the drainage ditch and reducing the seepage of the greenhouse due to untimely drainage in rainy and snowy weather.

[0035] By adjusting the fan shaft 142 in the fan unit 14 and adjusting the angle of the high-power fan 143, the residual water stains on the surface of the greenhouse after cleaning are blown to the drainage grooves on both sides, thereby reducing the problem of reduced light transmittance caused by scale after the water stains dry on the surface of the greenhouse. It also reduces the problem of traditional equipment requiring multiple cleanings due to residual sewage during the cleaning process.

[0036] By installing the wind direction component 15, during the use of the device, the generator 153 generates electricity driven by the fan blades 154 and stores it in the battery 13. If the wind force becomes stronger during the operation of the device, the generator 153 generates electricity through the rotation of the fan blades 154. When the power generation exceeds the set threshold, the threshold setting of 120%-150% of the rated wind speed is an over-limit state, which lasts for 10 seconds. The threshold reference formula is V threshold = k⋅V rated (k belongs to [1.2,1.5]), where V ratedThe IEC 61400-25 standard can be used for setting according to local conditions. After the threshold is triggered, the device will be powered off, and the power in the battery will drive the drive group 4 to reset the device to the starting position, thereby reducing the hazards and equipment damage that may occur due to bad weather.

[0037] The working principle of the technical solution provided by the present invention is as follows: The equipment is installed on the top of the greenhouse, and the greenhouse with a double-slope symmetrical appearance is adjusted according to the situation of the top of the greenhouse. The lifting seat 12 can be pulled up by the hydraulic device 11, so that it drives the telescopic support rod 203 to extend, and one side of the roller brush group 2 is lifted upward, so as to better adapt to the angle of the top of the greenhouse. For example, for a flat-top greenhouse, the hydraulic device 11 can be pressed down, and the bolts inside the adjustment frame 16 can be adjusted according to the situation of the top of the greenhouse, so that the angle of the cleaning plate 19 is offset and fits the top of the greenhouse to increase the cleaning range. When the flat-top greenhouse is used, the bolts inside the cleaning plate 19 adjustment frame 16 are loosened to adjust the angle of the cleaning plate 19, and then the bolts are tightened, and the cleaning plate 19 is located between the two roller brushes 205. The middle part of the equipment, the drive group 4 can make the device move forward and backward during the movement, turn on the electric water pump 22 to make the small nozzle 25 spray water, and the sludge in the forward position of the moving wheel 405 can be washed.
