Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a maintenance device for farmland water conservancy projects. Background Technology

[0002] To quickly clear debris clogging channels, a rotary fine bar screen cleaner can be used. The rotary fine bar screen cleaner can continuously and automatically intercept and remove debris of various shapes from the fluid, and is one of the most advanced solid-liquid screening devices in my country.

[0003] Existing rotary cleaning machines used in farmland irrigation projects also have some problems, such as:

[0004] 1. During prolonged use, the cleaning rake inside the machine may become stuck in the grid and unable to rotate. When encountering hard debris such as tree roots, the grid may deform, preventing the rake from passing through and causing obstruction.

[0005] 2. The machine body contains a large number of cleaning rakes, and each row of rakes is fixed to a connecting rod. When a rake inside the machine body malfunctions, the large number of rakes makes it difficult for operators to detect the problem in time. Even if operators do detect the rake malfunction, the large number of rakes on a single connecting rod means that replacing the entire connecting rod due to the malfunction of just one rake would obviously result in unnecessary economic losses and cause great inconvenience.

[0006] Therefore, a maintenance device for farmland irrigation projects is proposed. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the present invention provides a maintenance device for farmland water conservancy projects, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A maintenance device for farmland irrigation projects includes a mounting plate. Three rollers are rotatably mounted inside the mounting plate, and a conveyor belt is driven between the three rollers. Multiple mounting slots are evenly spaced inside the conveyor belt, and each mounting slot contains a toothed rake for cleaning debris from the channel. A fixing plate is fixedly mounted between two mounting plates. A vibration mechanism for cleaning debris from the rake is located between the fixing plate and the conveyor belt. Optical signal transmitters and optical sensors are fixedly mounted on the opposite sidewalls of the two mounting plates, respectively. A fixing shaft is fixedly mounted on the bottom of the two mounting plates, and a rotating mechanism for inspecting and maintaining the toothed rake is located outside the fixing shaft, cooperating with the optical signal transmitters and optical sensors.

[0010] Preferably, the vibration mechanism includes a plurality of first magnets fixedly installed at equal intervals inside the fixed plate, and a plurality of second magnets cooperating with the first magnets are also fixedly installed at equal intervals inside the conveyor belt. The polarity of each pair of adjacent first magnets is opposite, and the polarity of each pair of adjacent second magnets is also opposite.

[0011] Preferably, a connecting plate is fixedly installed in the middle of the two mounting plates, and a plurality of impurity removal rods are fixedly installed at equal intervals on the upper end of the connecting plate. The plurality of impurity removal rods are staggered from the toothed rake, and a scraper is fixedly installed on both sides of each impurity removal rod. The scraper is made of rubber.

[0012] Preferably, each of the impurity removal rods has a flow guide hole inside, a water storage bag is fixedly installed at the bottom of the fixing plate, and a water receiving trough is fixedly installed between the two mounting plates. The bottom of the water receiving trough is connected to the inside of the water storage bag, and the bottom of the water storage bag is connected to the flow guide holes inside the multiple impurity removal rods.

[0013] Preferably, the water storage bladder is provided with two sets of one-way valves. One set of one-way valves only allows water from the water inlet tank to enter the water storage bladder, while the other set of one-way valves only allows water from the water storage bladder to enter the guide hole.

[0014] Preferably, a controller is installed inside one side of the mounting plate, and the optical signal transmitter and optical sensor are electrically connected to the controller. A motor is also installed inside the other side of the mounting plate, and the motor is electrically connected to the controller.

[0015] Preferably, the rotating mechanism includes a rotating shaft fixedly installed at the end of the motor output shaft, a first gear fixedly installed at one end of the rotating shaft, a fixed cylinder fixedly installed outside the fixed shaft, a rotating cylinder rotatably installed outside the fixed cylinder, a second gear fixedly installed at one end of the rotating cylinder, the second gear meshing with the first gear, and a lever for actuating the rake fixedly installed outside the rotating cylinder.

[0016] Preferably, an oil pump is also provided inside the mounting plate on one side, the fixed shaft is hollow inside, one end of the oil pump is connected to the inside of the fixed shaft, the fixed cylinder is provided with a first oil guide hole that is connected to the cavity inside the fixed shaft, and the rotating cylinder and the lever are provided with a second oil guide hole that cooperates with the first oil guide hole.

[0017] Preferably, each of the mounting slots has a mounting shaft fixedly installed inside, the toothed rake is rotatably mounted outside the mounting shaft, a torsion spring is sleeved at the connection between the toothed rake and the mounting shaft, and a detachable tooth is installed at one end of each toothed rake.

[0018] Preferably, a collection device body that cooperates with the conveyor belt is provided between the two mounting plates. The collection device body is provided with a crushing roller inside and a guide belt at the bottom.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. When the equipment is working normally, the conveyor belt rotates continuously and uses multiple sets of toothed rakes to continuously remove the debris clogging the channel. The vibration mechanism can drive the conveyor belt to shake during the rotation of the conveyor belt, thereby shaking out the debris inside the conveyor belt.

[0021] 2. During the vibration of the conveyor belt, the vibrating rakes will approach the two side walls of the cleaning rod, thereby removing debris between multiple rakes and on both sides of a single rake. At the same time, water from the water tank is drawn into the water storage bladder and sprayed out through the guide hole inside the cleaning rod, thus washing away debris on the outer surface of the rakes and preventing debris from getting stuck.

[0022] 3. When the rake gets stuck or is damaged, the motor will start automatically and drive the rotating drum outside the fixed cylinder to rotate. This will drive the lever to move the abnormal rake. After being moved, the rake will vibrate slightly inside the mounting slot, which will shake out the debris inside the mounting slot and reduce the occurrence of the rake getting stuck.

[0023] 4. When the rake is moved, the oil pump can also spray lubricating oil through the second oil guide hole and the first oil guide hole to lubricate the rake and the mounting shaft. At the same time, it can also cooperate with the vibration of the rake so that the rake can return to its original position more quickly after being moved.

[0024] 5. If the rake fails to recover after being turned and abnormal signals occur in multiple rotation cycles, the controller will activate the buzzer to sound an alarm, and the operator can then repair or replace the rake. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 11 This invention provides a maintenance device for farmland irrigation projects, the technical solution of which is as follows:

[0039] A maintenance device for farmland irrigation projects includes a mounting plate 1. Three rollers 2 are rotatably mounted inside the mounting plate 1. A conveyor belt 3 is installed between the three rollers 2 for common transmission. Multiple mounting slots 4 are equally spaced inside the conveyor belt 3. Each mounting slot 4 is equipped with a toothed rake 6 for cleaning debris inside the channel. When the device is working normally, the two mounting plates 1 are equipped with a drive unit that drives the three rollers 2 to rotate, which in turn drives the conveyor belt 3 to rotate. When the conveyor belt 3 rotates, it drives the multiple sets of toothed rakes 6 inside to move continuously, thereby removing the debris silted up in the channel for cleaning. A fixing plate 7 is also fixedly installed between the two mounting plates 1. A vibration mechanism for cleaning debris inside the toothed rake 6 is provided between the fixing plate 7 and the conveyor belt 3.

[0040] The vibration mechanism can cause the conveyor belt 3 to vibrate during the rotation of the conveyor belt 3, thereby shaking out the debris inside the conveyor belt 3;

[0041] Optical signal transmitter 24 and optical sensor 25 are fixedly mounted on the opposite sidewalls of the two mounting plates 1, respectively. The optical signal transmitter 24 is model S32B-3011BA and the optical sensor 25 is model GY-30.

[0042] The optical signal transmitter 24 and the optical sensor 25 can detect the position status of the rake 6. If the rake 6 is damaged, it can be detected immediately, thus avoiding the situation where manual inspection is not timely.

[0043] The bottom of the two mounting plates 1 is also fixedly mounted with a fixed shaft 17. The outside of the fixed shaft 17 is provided with a rotating mechanism for maintenance of the toothed rake 6, which cooperates with the light signal transmitter 24 and the light sensor 25.

[0044] Reference Figure 9 as well as Figure 10 When the rake 6 is not damaged, if the conveyor belt 3 rotates normally, the time it takes for the light signal emitted by the light signal transmitter 24 to reach the light sensor 25 is fixed. When the rake 6 is damaged, the position between each set of rakes 6 will be misaligned. As a result, during the normal rotation of the conveyor belt 3, the time it takes for the light signal emitted by the light signal transmitter 24 to reach the light sensor 25 will be longer, thus enabling timely detection of the damage to the rake 6.

[0045] After the damage to the toothed rake 6 is detected, the rotating mechanism can be driven to move the toothed rake 6. If the toothed rake 6 is stuck by debris, the toothed rake 6 will reset after being moved.

[0046] If the rake 6 does not return to its original position after being moved, the damage will still be detected in the next stroke, thus notifying the operator in time to replace or repair the rake 6.

[0047] Reference Figure 4 as well as Figure 6 The vibration mechanism includes multiple first magnets 8 that are fixedly installed at equal intervals inside the fixed plate 7. Multiple second magnets 9 that cooperate with the first magnets 8 are also fixedly installed at equal intervals inside the conveyor belt 3. The polarity settings between any two adjacent first magnets 8 are opposite, and the polarity settings between any two adjacent second magnets 9 are also opposite.

[0048] As the conveyor belt 3 rotates, the multiple second magnets 9 embedded inside the conveyor belt 3 will take turns passing over the inside of the fixed plate 7. Since the polarities of adjacent first magnets 8 inside the fixed plate 7 are all opposite, and the polarities of adjacent second magnets 9 are also opposite, when the first magnets 8 inside the fixed plate 7 attract each other with the second magnets 9 inside the conveyor belt 3 during the rotation of the conveyor belt 3, in the next stroke, the first magnets 8 inside the fixed plate 7 and the second magnets 9 inside the conveyor belt 3 will repel each other. In the process of the first magnets 8 and the second magnets 9 continuously “attracting-repelling-attracting”, the position where the conveyor belt 3 and the fixed plate 7 are close to each other will continuously shake, thereby shaking out the debris inside the mounting groove 4 and between each set of toothed rakes 6, thus reducing the manual cleaning steps.

[0049] Reference Figures 2-4 as well as Figure 11 A connecting plate 10 is fixedly installed in the middle of the two mounting plates 1. Multiple cleaning rods 11 are fixedly installed at equal intervals on the upper end of the connecting plate 10. The multiple cleaning rods 11 are all staggered from the toothed rake 6. A scraper is fixedly installed on both sides of each cleaning rod 11. The scraper is made of rubber.

[0050] As the conveyor belt 3 rotates, the debris removal rod 11 passes between every two adjacent rakes 6. As the conveyor belt 3 vibrates, the vibrating rakes 6 come into contact with the scrapers on both sides of the debris removal rod 11, thereby removing debris between multiple rakes 6 and on both sides of a single rake 6.

[0051] Reference Figure 4 as well as Figure 6Each impurity removal rod 11 has a flow guide hole inside. A water storage bladder 12 is fixedly installed at the bottom of the fixing plate 7. A water receiving trough 13 is also fixedly installed between the two mounting plates 1. The water receiving trough 13 can collect the water flowing down from the impurities and filter the water itself. The water receiving trough 13 can also be connected to an external water pump. If the water collected inside the water receiving trough 13 is insufficient, water can be supplied directly through the water pump. The bottom of the water receiving trough 13 is connected to the inside of the water storage bladder 12. The bottom of the water storage bladder 12 is connected to the flow guide holes inside the multiple impurity removal rods 11.

[0052] The water storage bladder 12 is equipped with two sets of one-way valves. One set of one-way valves only allows water from the water tank 13 to enter the water storage bladder 12, while the other set of one-way valves only allows water from the water storage bladder 12 to enter the guide hole.

[0053] As the conveyor belt 3 vibrates continuously, it intermittently squeezes the water storage bladder 12 at the bottom of the fixed plate 7, thereby drawing water from the water receiving tank 13 into the water storage bladder 12 and spraying it out through the guide hole inside the impurity removal rod 11, thus washing away the impurities on the outer surface of the toothed rake 6 and preventing the impurities from getting stuck on the toothed rake 6.

[0054] Reference Figures 3-5 as well as Figures 7-10 The mounting plate 1 on one side is equipped with a controller. The light signal transmitter 24 and the light sensor 25 are electrically connected to the controller. The light transmission path between the light signal transmitter 24 and the light sensor 25 is located at the root of the rake 6. The mounting plate 1 on one side is also equipped with a motor, which is electrically connected to the controller. The controller is also connected to a buzzer, which can issue an alarm in time after equipment failure.

[0055] When the rake 6 gets stuck or is damaged, the position of each set of rakes 6 will be misaligned. As a result, during the normal rotation of the conveyor belt 3, the light signal emitted by the light signal transmitter 24 will take longer to reach the light sensor 25 due to the obstruction of multiple sets of overlapping rakes 6. After detecting the abnormal state of the rake 6, the abnormal signal will be transmitted to the inside of the controller, thereby starting the motor.

[0056] The rotating mechanism includes a rotating shaft 15 fixedly installed at the end of the motor output shaft. A first gear 16 is fixedly installed at one end of the rotating shaft 15. After the motor rotates, it will drive the rotating shaft 15 and the first gear 16 to rotate. A fixed cylinder 18 is fixedly installed on the outside of the fixed shaft 17. A rotating cylinder 19 is rotatably installed on the outside of the fixed cylinder 18. A second gear 20 is fixedly installed at one end of the rotating cylinder 19. The second gear 20 meshes with the first gear 16. A lever 21 for actuating the toothed rake 6 is fixedly installed on the outside of the rotating cylinder 19.

[0057] After the first gear 16 drives the second gear 20 to rotate, it will drive the rotating cylinder 19 outside the fixed cylinder 18 to rotate, thereby driving the lever 21 to move the abnormal rake 6.

[0058] Reference Figures 9-10 Each mounting slot 4 has a mounting shaft 5 fixedly installed inside. The toothed rake 6 is rotatably mounted on the outside of the mounting shaft 5. A torsion spring 14 is also sleeved at the connection between the toothed rake 6 and the mounting shaft 5. Each toothed rake 6 has a detachable tooth installed at one end. The tooth is fixedly connected to the root of the toothed rake 6 by bolts. The tooth is relatively thin and is easily damaged. Now, if the tooth is damaged, the bolts can be removed to repair the toothed rake 6 more quickly.

[0059] The lower end of the toothed rake 6 is rotatably mounted on the outside of the mounting shaft 5 and is elastically connected to the mounting shaft 5 through a torsion spring 14. Therefore, after the toothed rake 6 is moved, it will vibrate slightly inside the mounting groove 4, which can shake out the debris inside the mounting groove 4, thereby reducing the occurrence of the toothed rake 6 getting stuck.

[0060] Reference Figures 4-7 An oil pump is also installed inside the mounting plate 1 on one side. The fixed shaft 17 is hollow inside. One end of the oil pump is connected to the inside of the fixed shaft 17. The fixed cylinder 18 has a first oil guide hole 22 that is connected to the cavity inside the fixed shaft 17. The rotating cylinder 19 and the lever 21 have a second oil guide hole 23 that cooperates with the first oil guide hole 22.

[0061] During the rotation of the drum 19, when the lever 21 is about to actuate the rake 6, the first oil guide hole 22 is connected to the second oil guide hole 23, so that the oil pump can spray lubricating oil through the second oil guide hole 23 and the first oil guide hole 22 to lubricate the rake 6 and the mounting shaft 5. At the same time, it can also cooperate with the vibration of the rake 6 so that the rake 6 can return to its original position more quickly after being actuated.

[0062] During the continuous rotation of the conveyor belt 3, the toothed rake 6, after being sprayed with lubricating oil, will come into contact with the cleaning rod 11 again during subsequent rotations. Since the cleaning rod 11 must scrape away the debris through the contact between the scraper and the toothed rake 6, this contact process will also cause the toothed rake 6 to vibrate slightly, thereby allowing the lubricating oil to penetrate more thoroughly between the toothed rake 6 and the mounting shaft 5.

[0063] During the normal rotation of conveyor belt 3, the time for one rotation cycle of conveyor belt 3 is fixed. If the toothed rake 6 still cannot recover after being moved, and abnormal signals occur in multiple rotation cycles, the controller will control the buzzer to sound an alarm, and then the operator can repair or replace the toothed rake 6.

[0064] Reference Figure 4 Between the two mounting plates 1, there is also a collection device body 26 that cooperates with the conveyor belt 3. The inside of the collection device body 26 is equipped with a crushing roller, and the bottom of the collection device body 26 is equipped with a guide belt.

[0065] Working principle: During normal operation, the conveyor belt 3 rotates continuously, and multiple sets of toothed rakes 6 continuously remove debris clogging the channel. The vibration mechanism drives the conveyor belt 3 to vibrate during rotation, thereby shaking out debris inside the conveyor belt 3. During the vibration of the conveyor belt 3, the vibrating toothed rakes 6 approach the side walls of the debris removal rod 11, thereby removing debris between multiple toothed rakes 6 and on both sides of a single toothed rake 6. At the same time, water from the water receiving tank 13 is drawn into the water storage bladder 12 and sprayed out through the guide holes inside the debris removal rod 11, thus washing away debris on the outer surface of the toothed rakes 6, preventing debris from jamming the toothed rakes 6. If a toothed rake 6 becomes jammed or damaged, the motor will automatically start, driving the fixed cylinder 18 to move outward. The rotating drum 19 of the part rotates, thereby driving the lever 21 to move the abnormal rake 6. After being moved, the rake 6 will vibrate slightly inside the mounting groove 4, which can shake out the debris inside the mounting groove 4, thereby reducing the occurrence of the rake 6 getting stuck. When the rake 6 is moved, the oil pump can also spray lubricating oil through the second oil guide hole 23 and the first oil guide hole 22 to lubricate the rake 6 and the mounting shaft 5. At the same time, it can also cooperate with the vibration of the rake 6 to make the rake 6 return to its original position more quickly after being moved. If the rake 6 still cannot return to its original position after being moved and abnormal signals appear in multiple rotation cycles, the controller will control the buzzer to sound an alarm, and then the operator can repair or replace the rake 6.

[0066] It will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
