DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-15 The present invention provides a technical solution: an automatic cleaning system for ditch water pollution, including a vehicle body 1 moving above the ditch, the vehicle body 1 includes two moving bodies 101 moving synchronously on both sides of the ditch, a crossbeam 102 is fixedly connected between the two moving bodies 101, and a height-adjustable lifting rod 2 is provided above the vehicle body 1, such as Figure 6-7 As shown, a fork shear device 11 is provided between the lifting rod 2 and the vehicle body 1, the upper end of the fork shear device 11 is connected to the lifting rod 2, and the lower end of the fork shear device 11 is connected to the vehicle body 1. After the fork shear device 11 is started and deformed, the lifting rod 2 is driven to change its height. The fork shear device 11 is a prior art product, so it is not described in detail. The internal rotation of the lifting rod 2 is connected to a screw rod 3, as shown in FIG. Figure 8As shown, a first motor 301 is provided at one end of the screw rod 3, and the first motor 301 is fixedly connected to the side wall of the lifting rod 2. The output shaft of the first motor 301 is connected to the end of the screw rod 3. When the first motor 301 is started, the output shaft of the first motor 301 drives the screw rod 3 to rotate. Two cleaning devices 4 are symmetrically meshed and connected to the screw rod 3 for removing the weeds in the ditch and pushing them into the water inside the ditch. A compression device 5 for compressing the weeds is provided on the vehicle body 1, and a lifting device 6 for lifting the weeds in the ditch water into the compression device 5 is also provided on the vehicle body 1.

[0033] In order to remove the weeds on the bank of the ditch, the cleaning device 4 includes a mechanical arm 401, and a cleaning bucket 402 is provided at the lower end of the mechanical arm 401. The cleaning bucket 402 is driven to rotate by a first oil cylinder 403. Figure 8 , 9 As shown, the first oil cylinder 403 is rotatably mounted on the side wall of the mechanical arm 401, the cleaning bucket 402 is rotatably connected to the mechanical arm 401, and the side walls of the cleaning bucket 402 and the mechanical arm 401 are rotatably connected with a connecting rod 17, and the output shaft of the first oil cylinder 403, the cleaning bucket 402 and the end of the connecting rod 17 on the mechanical arm 401 are rotatably connected at one point. When the first oil cylinder 403 is started, the output shaft of the first oil cylinder 403 applies a pulling force or a pushing force to the cleaning bucket 402 and the connecting rod 17 on the mechanical arm 401, thereby realizing the first oil cylinder 403 driving the cleaning bucket 402 to change its angle. The cleaning bucket 402 is adapted to ditches with different slopes. A cutting tooth 404 is fixedly connected to the side wall of the opening of the cleaning bucket 402. The cutting tooth 404 includes a fixed tooth 4041 and a movable tooth 4042. The fixed tooth 4041 is provided with a movable tooth 4042 which reciprocates. The movable tooth 4042 and the fixed tooth 4041 are connected to each other in a close fit. When the movable tooth 4042 reciprocates, the teeth of the movable tooth 4042 and the fixed tooth 4041 continuously stagger, thereby achieving weed cutting. The movable tooth 4042 is driven to slide by the second motor 405.

[0034] like Fig.10As shown, a waist-shaped groove 12 is formed on the side wall of the movable tooth 4042, and the bolt 13 on the cleaning bucket 402 penetrates the waist-shaped groove 12 and the side wall of the fixed tooth 4041, thereby fixing the fixed tooth 4041 on the cleaning bucket 402, and realizing the reciprocating motion of the movable tooth 4042, and then the movable tooth 4042 and the fixed tooth 4041 continuously move in an interlaced manner to remove the weeds. In addition, the second motor 405 is fixedly installed inside the cleaning bucket 402, and the output shaft of the second motor 405 is fixedly connected to a rotating disk 14, and an eccentric column 15 is fixedly connected to the side wall of the rotating disk 14 away from the center of the circle, and the eccentric column 15 is slidably connected to the inside of the slide groove 16, and the slide groove 16 is formed on the side wall of the movable tooth 4042. When the second motor 405 is started, the rotating disk 14 rotates with the eccentric column 15, and at this time, the eccentric column 15 slides inside the slide groove 16 to realize driving the movable tooth 4042 to reciprocate;

[0035] like Figure 2 As shown, after the device is placed above the ditch, the two cleaning devices 4 are located on both sides of the ditch, and the two mechanical arms 401 are symmetrically moved by the rotation of the screw 3, so that the two cleaning buckets 402 are located at the uppermost sides of the two sides of the ditch. At this time, the angle of the cleaning bucket 402 is driven by the first oil cylinder 403, so that the cutting teeth 404 are at the best angle for weeding (that is, the lower side of the cleaning bucket 402 is parallel to the slope of the two sides of the ditch), and the movable teeth 4042 are started to make the movable teeth 4042 and the fixed teeth 4041 move crosswise, and then the fork shear device 11 and the screw 3 are started to realize the movement of the cleaning bucket 402 downward along the slope of the ditch. At this time, the cutting teeth 404 remove the weeds, and the cleaning bucket 402 will push the removed weeds into the water of the ditch for cleaning, thereby realizing the effect of quickly removing the weeds on the ditch bank.

[0036] In order to achieve a more thorough cleaning of the removed weeds, specifically, a row of high-pressure nozzles 7 are provided on the side wall of the cleaning bucket 402, and the spray angle of the high-pressure nozzles 7 is directly facing the inner cavity of the cleaning bucket 402. When the cutting teeth 404 remove the weeds, the removed weeds will be shoveled into the interior of the cleaning bucket 402. At this time, the high-pressure nozzles 7 spray high-pressure water columns on the weeds shoveled into the cleaning bucket 402, thereby removing the soil impurities on the weeds (flushing the soil impurities firmly attached). In addition, the cleaning The side wall of the cleaning bucket 402 is in the shape of a grating, and the water used to clean the weeds carries soil impurities and flows out from the grating holes of the cleaning bucket 402 to avoid water accumulation inside the cleaning bucket 402. A water tank 8 is rotatably connected to the side wall of the cleaning bucket 402, and a water inlet 801 is provided on the upper side of the water tank 8. When the cleaning bucket 402 is inside the ditch water, the water in the ditch will enter the inside of the water tank 8 from the water inlet 801 to ensure that the inside of the water tank 8 is filled with water, and a counterweight block 802 is fixedly connected to the lower side of the water tank 8. Fig.11As shown, the added counterweight 802 can make the water inlet 801 always be directly above, and when the cleaning bucket 402 rotates, the water inside the water tank 8 is effectively prevented from flowing out. In addition, a filter is provided at the water inlet 801 to prevent impurities from entering the inside of the water tank 8. The high-pressure nozzle 7 is connected to the water tank 8 through a water pipe, and a water pump 9 is connected in series on the water pipe. The water pump 9 is fixedly installed in the middle part of the cleaning bucket 402 and is covered by a cover body without affecting the operation. When the water pump 9 is started, the water pump 9 will absorb the water inside the water tank 8 and spray the water from the high-pressure nozzle 7.

[0037] In order to compress the weeds into blocks for transportation and storage, the compression device 5 comprises a storage box 501. The interior of the storage box 501 is divided into a feeding chamber 5011 and a compression chamber 5012. Figure 5 As shown, the space of the feed chamber 5011 is relatively large, and the compression chamber 5012 is a narrow square space. The feed chamber 5011 and the compression chamber 5012 are transitioned by an inclined wall, and the bottoms of the feed chamber 5011 and the compression chamber 5012 are both provided with water leakage holes, and the water in the weeds can flow out through the water leakage holes. The upper side wall of the feed chamber 5011 is provided with a feed port 508, and the interior of the feed chamber 5011 is slidably connected to a push plate 503 through a second oil cylinder 502, as shown in FIG. Figure 5 As shown, the second oil cylinder 502 is fixedly connected to the cross beam 102, and the output shaft of the second oil cylinder 502 is fixedly connected to the side wall of the push plate 503. When the second oil cylinder 502 is started, the output shaft of the second oil cylinder 502 pushes the push plate 503 to slide inside the feed chamber 5011, so that the push plate 503 pushes the weeds inside the feed chamber 5011 into the compression chamber 5012. The end of the compression chamber 5012 away from the feed chamber 5011 is provided with a cutter 504 for evenly cutting the compressed weed strips into blocks. The cutter 504 is driven to slide by the third oil cylinder 505. Figure 4As shown, the third oil cylinder 505 is fixed to the side wall of the storage box 501 through a bracket, and the cutter 504 is fixed to the output shaft of the third oil cylinder 505. When the third oil cylinder 505 is started, the cutter 504 slides downward with the third oil cylinder 505 to cut the weeds sliding out of the compression chamber 5012 into blocks. The end of the compression chamber 5012 away from the feed chamber 5011 is also provided with a blocking plate 507 through a spring 506. The blocking plate 507 plays a role in blocking the outlet of the compression chamber 5012. When the weeds slide out of the compression chamber 5012 after being compressed , the weed block will push open the blocking plate 507, and the blocking plate 507 will overcome the elastic force of the spring 506 and slide along with the weeds, so as to clamp the weed block to a certain extent and prevent the weed block from being scattered due to its own gravity. When the weed block slides out to a certain length, the third oil cylinder 505 is started, and the cutter 504 cuts off the weed block from the mouth of the compression chamber 5012. At this time, the weed block outside the compression chamber 5012 falls downward to the ground (it can be pushed downward by the staff), and the blocking plate 507 is reset to the position as shown in the figure below by the elastic force of the spring 506. Figure 4 Status shown.

[0038] Furthermore, in order to facilitate the weed blocks to slide out to one side of the ditch for subsequent collection, and to minimize the influence of gravity on the weed blocks during discharge, the shape of the weed blocks is made more regular, such as Fig.13 Limiting plates 19 are fixedly connected to both sides of the lower side of the storage box 501. The limiting plates 19 are connected to two groups of rotating rods 21 on the supporting plate 18 through the limiting grooves 20 thereon, and one group of rotating rods 21 is connected to the blocking plate 507 through a rotating shaft and a U-shaped rod. As shown in the figure, an arc groove 22 is provided at the end of the limiting plate 19. When the blocking plate 507 moves outward, the supporting plate 18 will be linked to move outward, thereby supporting the weed blocks and preventing them from scattering. When a group of rotating rods 21 at the outer end moves to above the arc groove 22, the supporting plate 18 is tilted due to gravity, and the divided weed blocks are discharged along the supporting plate 18 to one side of the ditch. In response to this situation, the spring 506 can adopt a model with a low elastic coefficient to facilitate pulling the blocking plate 507. A water leakage hole is also provided on the supporting plate 18, and water in the weeds can flow out along the water leakage hole.

[0039] When the amount of weeds is small, it is easier to compress them. Fig.15 The push plate 503 includes a main plate 5031, a sub-plate 5032, a compression spring 5033 and a roller 5034. The lower end of the sub-plate 5032 is movably connected to the main plate 5031 through the compression spring 5033, and the top of the sub-plate 5032 is rotatably installed with a roller 5034. When entering the trapezoidal stage, the sub-plate 5032 can be retracted into the main plate 5031 to compress the weeds, thereby adapting to the internal shape changes of the storage box 501.

[0040] In order to lift the weeds in the ditch water to the inside of the storage box 501, specifically, the lifting device 6 includes a bucket 601, and the bucket 601 is installed on the side wall of the vehicle body 1 through a fourth oil cylinder 602. Figure 4 As shown, the fourth oil cylinder 602 is fixed on the vehicle body 1, and the end of the output shaft of the fourth oil cylinder 602 is fixedly connected to the side wall of the barrel 601, which can not only fix the barrel 601, but also adjust the height of the barrel 601. The inner rotation of the barrel 601 is connected to a turbine 603, and the turbine 603 is driven to rotate by a third motor 604. The third motor 604 is fixedly connected to the upper end side wall of the barrel 601, and the output shaft of the third motor 604 is connected to the end of the turbine 603. When the third motor 604 is started, the output shaft of the third motor 604 drives the turbine 603 to rotate. A suction hole 605 is opened at the bottom of the barrel 601. Since the weeds in the water generally float on the water surface, Figure 3 As shown, the suction hole 605 is at the horizontal plane of the ditch. After the fourth oil cylinder 602 drives the material barrel 601 to move up and down, the height of the suction hole 605 is adjusted, so that it is suitable for use in ditches with different water levels. A discharge pipe 606 is provided above the material barrel 602, and the end of the discharge pipe 606 is located just above the feed port 508. Figure 5 As shown, when the turbine 603 rotates, the weeds in the ditch water will enter the barrel 601 from the suction hole 605, and move upward along the inside of the barrel 601, and finally be discharged from the discharge pipe 606 and fall into the inside of the feed cavity 5011 from the inside of the feed port 508. In order to minimize the water content in the weeds, the vortex pitch and the size of the vortex blades of the turbine 603 gradually decrease from bottom to top, so that the space between the turbine 603 and the barrel 601 gradually decreases from bottom to top, which can also play a role in compressing the weeds and draining water during the lifting process.

[0041] In order to gather the weeds in the ditch water to the suction hole 605 , specifically, baffles 10 for gathering the weeds to the suction hole 605 are fixedly connected to the side walls of the barrel 602 on both sides of the suction hole 605 .

[0042] Working principle: When in use, the device can be placed by external lifting equipment (crane, etc.), and the placement state is: two moving bodies 101 are located on both sides of the ditch, and the crossbeam 102 is placed above the ditch through the two moving bodies 101 (such as Figure 1As shown in the figure, the cleaning device 4 removes the weeds on both sides of the ditch and pushes them into the water of the ditch for cleaning through the cooperation of the fork shear device 11 and the screw rod 3. The weeds in the ditch water (the removed weeds and the original duckweed in the water) are gathered to the middle by two cleaning buckets 402. Then, the weeds in the ditch water are lifted to the inside of the storage box 501 by the lifting device 6 and compressed, which is convenient for subsequent transportation and storage (for use as agricultural feed), thereby improving the weed removal efficiency and utilization rate;

[0043] The steps to remove weeds are:

[0044] Step 1: The vehicle body 1 is stationary, and the cleaning device 4 removes the weeds on both sides of the ditch and pushes them into the water of the ditch for cleaning through the cooperation of the fork shear device 11 and the screw rod 3;

[0045] Step 2: Reset the cleaning device 4 (such as Figure 3 As shown), the vehicle body 1 is moved by a distance equal to the length of the cleaning bucket 402, and at the same time, the lifting device 6 is started to lift the weeds that were removed in the first step and pushed into the ditch water to the interior of the compression device 5;

[0046] Step 3: The vehicle body 1 is stationary, and then the action of the first step is repeated, the lifting device 6 is closed, and at the same time, the second oil cylinder 502 is started, and the weeds in the feeding chamber 5011 are pushed into the compression chamber 5012 by the push plate 503, and then the second oil cylinder 502 drives the push plate 503 to reset;

[0047] Repeat the first to third steps to clean the ditch weeds. At the same time, the operator drives the cutter 504 to cut according to the length of the weed block sliding out of the compression chamber 5012. In addition, a driving cabin can be added to any mobile body 101, and the operator sits in the driving cabin to operate the device.
