Description

Technical Field

[0001] This invention relates to the field of pesticide spraying technology, and in particular to an electric double-row sprayer that can be used by two people. Background Technology

[0002] In modern agriculture, sprayers are a common agricultural piece of equipment, widely used for spraying pesticides and plant protectants to improve crop yield and quality. However, most sprayers on the market today are single-row nozzle designs. Single-row nozzle sprayers are typically operated by a single person, have limited spray coverage, and cannot quickly and effectively treat large areas of farmland. When it is necessary to quickly complete the control of large-scale pests and diseases, the working efficiency of single-row nozzle sprayers is inadequate.

[0003] Chinese patent application CN202323359058.9 discloses an automatic spraying tube retraction machine, comprising a body assembly and a spraying assembly. The body assembly includes a medicine tank, a handle on the side of the medicine tank, and a control panel fixed to the medicine tank. The spraying assembly is mounted on the medicine tank and includes a partition cylinder located in the middle of the medicine tank. This invention utilizes the spraying assembly to allow the spraying pump to draw liquid medicine into a hydraulic lifting rod when the solenoid valve is opened. The hydraulic lifting rod then extends under pressure, pushing the spraying tube upwards. Under the action of a spring, the spraying tube opens to both sides, allowing the medicine to enter the spraying tube through the hydraulic lifting rod and then be sprayed from the nozzle. After spraying is complete, the spraying pump discharges the liquid medicine from the hydraulic lifting rod into the medicine tank, at which point the hydraulic lifting rod retracts, completing the retraction of the spraying tube. This solution eliminates the need for manual handling of the spraying tube, achieving automatic retraction and facilitating long-term operation.

[0004] However, during use, the pipe is prone to touching the ground and getting dirty with dust and sludge. This not only affects the spraying effect, but if the pipe is not cleaned during winding, dirt will accumulate and the pipe will be damaged after winding, increasing the maintenance cost and usage risk of the equipment. Furthermore, the spray gun is not well fixed after winding, which can easily cause the spray gun to collide with the device and cause damage to the spray gun.

[0005] In conclusion, the research and application of electric double-row pipe sprayers for two-person use is expected to solve the problems of low efficiency, high labor costs, and dirty and damaged pipes that exist in existing single-row pipe sprayers, providing a more efficient, safe and reliable spraying solution for modern agriculture.

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

[0020] 1. This invention allows two operators to perform synchronous spraying using the two-sided take-up rollers. With two people working together, the working area can be significantly expanded and the working time shortened, thereby improving the overall work efficiency. It also allows for flexible selection of gasoline or diesel engines as power sources. This diversified power configuration enables the equipment to perform at its best in various complex and changing agricultural environments.

[0021] 2. By controlling the two take-up rollers to rotate counterclockwise simultaneously, combined with manual pulling and the reciprocating movement of the slider, the unwinding spray pipe is guided to ensure the orderly release of the spray pipe during the unwinding process. The third electric push rod retracts, driving the third guide wheel to rise to the same height as the second guide wheel, reducing the contact area between the spray pipe surface and the guide wheel, and reducing additional tension and friction. During the winding process, the piston plate reciprocates inside the rectangular cylinder. By switching the state of the first solenoid valve and the second solenoid valve, the liquid in the water tank is sucked in and continuously pushed out, continuously cleaning the surface of the spray pipe.

[0022] 3. The liquid inside the cleaning box is initially relatively clean and used for initial rinsing. As the winding process progresses, the amount of liquid and impurities increases. By adjusting the height of the third guide wheel, the cleaner liquid at the top is used to continue soaking and treating the spray pipe. During the retraction of the third electric push rod, the inclined rod, cylindrical rod, and spray ring move synchronously. Through the extension and rotation of the passive telescopic rod, the height and tilt angle of the spray ring are ensured to be parallel to the spray pipe, ensuring a proper rinsing angle. The secondary treatment of the spray pipe is achieved through soaking and rinsing, ensuring the cleaning effect.

[0023] 4. With the cooperation of the winding assembly, the spray pipe is wound in multiple layers. By controlling the phased extension of the first electric push rod, the tension on the spray pipe does not increase during the multi-layer winding, and the cleaning box is driven to descend to perform the sewage discharge operation, ensuring that there is always a lot of liquid inside the cleaning box, and that the sludge is collected in the cleaning box, and the liquid inside the cleaning box will not overflow.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figures 1-11 The specific embodiments of the present invention will be described in further detail.

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

[0038] Example 1:

[0039] Depend on Figures 1-11This invention proposes an electric double-row sprayer for two-person use. The invention includes a frame 101 made of high-quality metal to ensure stability and durability. A flat plate 105 is located on the top of the frame 101. Two take-up rollers 108 are located inside the frame 101, and their outer sides are rotatably connected to the frame 101. A gear ring 109 is located on the outer side of each take-up roller 108, and a one-way gear 107 meshes with the top of the gear ring 109. The one-way gear 107 is located on the right side. A booster pump 104 is installed inside the platform, and a second motor 103 is installed inside the booster pump 104. The bottoms of the first motor 102, the second motor 103, and the booster pump 104 are all fixedly connected to the platform. The first motor 102 is installed inside the left one-way gear 107, and a high-efficiency booster pump 104 is connected inside the right one-way gear 107. The booster pump 104 is powered by the second motor 103 to increase the internal pressure of the spray pipe 111, ensuring that the liquid can be sprayed evenly and powerfully onto the crops. A first motor 102 is connected to the inner side of the one-way gear 107 on the left, providing driving force to the take-up roller 108 on the left. A take-up assembly is provided on the outer rear of the take-up roller 108. The take-up assembly can effectively fix and guide the spray pipe 111, preventing it from getting tangled or falling off during take-up or release. A slider 204 is provided on the top of the take-up assembly, and a take-up frame 205 is provided on the top of the slider 204. Spray pipes 111 are provided on the outer side of the take-up roller 108. The rear end of the spray pipe 111 passes through the box 502, the slider 204 and the take-up frame 205. A spray gun 112 is provided at the top of the spray pipe 111. The slider 204 can move back and forth left and right as the device operates. The spray pipe 111 passes through The retractor 205 and slider 204 are included. The retractor 205 has multiple pulleys inside, which can reduce the friction of the spray pipe 111 during retraction and detour, and reduce the wear of the spray pipe 111. The high-pressure liquid can be atomized and sprayed out through the spray gun 112 to complete the spraying operation of crops. The electric double-row pipe sprayer of the present invention can not only be driven by electricity, but also flexibly select gasoline engine or diesel engine as power source. This diversified power configuration enables the equipment to perform at its best in various complex and changeable agricultural environments. Whether in urban suburbs with sufficient power supply or in remote rural areas with inconvenient power, the equipment can easily cope with the situation and provide strong support for agricultural production.

[0040] Two take-up rollers 108 are symmetrically arranged about the center line of the flat plate 105. The front end of the booster pump 104 is provided with two booster pipes 106, which are symmetrically arranged about the center line of the booster pump 104. The booster pump 104 has one inlet and two outlets to complete the pressurization and diversion operation. The rear end of the booster pipe 106 is provided with a connecting pipe 110. The pressurized liquid enters the interior of the connecting pipe 110 through the booster pipe 106. The connecting pipe 110 can rotate with the take-up rollers 108 and is connected by a special rotating joint. This rotating joint is usually provided with a sealing ring and a bearing inside, which can allow the pipe to rotate freely within a certain range and ensure the sealing performance. The connecting pipe 110 is connected to the take-up rollers 108. The top of the connecting pipe 110 is connected to the spray pipe 111. The liquid enters the top of the connecting pipe 110 and then sprays out from the spray pipe 111.

[0041] The winding assembly includes a gear set 201, which is connected to the frame 101. The gear set 201 consists of multiple gears of different sizes and numbers of teeth. These gears transmit power and adjust the rotation speed through precise meshing. A reciprocating screw 202 is provided on the inner rear side of the gear set 201. The outer side of the reciprocating screw 202 cooperates with the slider 204. A guide rod 203 is provided on the rear side of the slider 204, and the guide rod 203 is connected to the frame 101. When the sprayer starts working, the winding roller 108 starts to rotate under the drive of the motor, and the gears transmit power and adjust the rotation speed through precise meshing. Driven by the gear set 201, the reciprocating screw 202 rotates accordingly. At this time, the slider 204 moves linearly back and forth along the guide rod 203 under the drive of the reciprocating screw 202, thereby driving the spray pipe 111 to perform orderly winding and unwinding. Due to the precise cooperation between the gear set 201 and the reciprocating screw 202, the slider 204 moves a precise distance for each rotation of the winding roller 108, realizing the spiral winding of the spray pipe 111. This design not only ensures the orderliness and non-tangling of the spray pipe 111 during the winding process, but also improves the reliability and durability of the equipment.

[0042] This equipment allows two operators to control the take-up rollers 108 on both sides respectively to perform synchronous or asynchronous spraying operations. With two people working together, the working area can be significantly expanded and the working time can be shortened, thereby improving the overall work efficiency. The take-up assembly adopts the precise cooperation of the gear set 201 and the reciprocating screw 202 to ensure the orderly and knot-free operation of the spray pipe 111 during the take-up process. When the take-up roller 108 rotates, the slider 204 moves in a straight line along the guide rod 203 under the drive of the reciprocating screw 202, thereby driving the spray pipe 111 to be wound and unwound in an orderly manner. This design not only improves the reliability and durability of the equipment, but also allows two operators to complete the take-up and unwound work of the spray pipe 111 more efficiently and orderly.

[0043] Example 2:

[0044] Based on Embodiment 1, this embodiment takes into account that when the device is in use, the pipe is prone to touching the ground and getting dirty and muddy. If the pipe is not cleaned during winding, it will lead to the accumulation of dirt and damage to the pipe after winding, which will increase the maintenance cost and usage risk of the equipment. Furthermore, the fixing effect of the spray gun 112 after winding is not good, which may cause the spray gun 112 to collide with the device and cause damage to the spray gun 112.

[0045] Specifically, each slider 204 has a box 502 at its bottom. The box 502 contains an adjustment component that works in conjunction with the spray pipe 111. The adjustment component can change the movement trajectory of the spray pipe 111 and clean it within the box 502. The right side of the adjustment component has a slant rod 701, and the top of the slant rod 701 has a spray ring 406. Multiple spray heads 407 are arranged circumferentially inside the spray ring 406. The adjustment component can move the spray ring 406 by moving it via the slant rod 701. The bottom of the spray ring 406 has a drain component, and the rear side of the adjustment component has a cleaning box 601. The drain component can continuously drain liquid as the slider 204 moves back and forth. The liquid is sprayed out through the spray heads 407 inside the spray ring 406 to rinse the spray pipe 111, washing away dirt and impurities. The wastewater flows into the cleaning box 601 for collection.

[0046] The drainage assembly includes a vertical plate 501, which is connected to the right-side box 502. The box 502 and the vertical plate 501 move with the reciprocating movement of the slider 204. A right-angle rod 303 is provided at the bottom of the vertical plate 501, and a piston rod 305 is provided at the front end of the right-angle rod 303. A piston plate 306 is provided on the right side of the piston rod 305. A telescopic plate 307 is provided inside the piston plate 306, and a rectangular cylinder 304 is provided on the outside of the piston plate 306. The bottom of the rectangular cylinder 304 is connected to the frame 101. The vertical plate 501 drives the piston plate 306 to move left and right inside the rectangular cylinder 304 through the right-angle rod 303 and the piston rod 305. The extension and retraction of the telescopic plate 307 can change the communication state between the piston plate 306 and the left and right cavities inside the rectangular cylinder 304.

[0047] A first solenoid valve 308 is located on the left rear side of the rectangular cylinder 304, and a second solenoid valve 309 is located on the right rear side of the rectangular cylinder 304. A liquid distribution pipe 302 is connected to the rear sides of the first and second solenoid valves 308 and 309. A water tank 301 is located on the top right side of the liquid distribution pipe 302. The inner side of the water tank 301 is connected to the frame 101. The interior of the water tank 301 can be used to hold liquid. The liquid reaches the connection points of the first solenoid valve 308 and the second solenoid valve 309 through the liquid distribution pipe 302. By actively controlling the opening and closing states of the first and second solenoid valves 308 and 309, continuous liquid intake from inside the rectangular cylinder 304 is achieved. Two one-way valves 401 are located at the top of the rectangular cylinder 304, with the center line of the rectangular cylinder 304 as the reference point. The weighing shafts are arranged symmetrically from left to right. By moving the piston plate 306 left and right, the liquid inside the rectangular cylinder 304 can be discharged through the one-way valve 401. The flow direction of the one-way valve 401 is from the inside of the rectangular cylinder 304 to the outside. The rear side of the one-way valve 401 is provided with a first hose 402. The outer end of the first hose 402 is connected to the liquid distribution box 403. The bottom of the spray ring 406 is provided with a second hose 405. The top of the liquid distribution box 403 is connected to the second hose 405 on the right side. The liquid flows into the liquid distribution box 403 through the first hose 402. The left side of the liquid distribution box 403 is provided with an extension tube 404. The top of the extension tube 404 is connected to the second hose 405 on the left side. With the help of the extension tube 404, the liquid can be delivered to the spray rings 406 on the left and right sides respectively.

[0048] The adjustment assembly includes a third electric actuator 602, the bottom of which is provided with a third guide wheel 603, such as... Figure 9As shown, after the spray pipe 111 enters the box 502, during winding, it first passes through the third guide wheel 603 rotatably connected to the bottom of the third electric push rod 602. The top of the third electric push rod 602 is connected to the box 502. A second electric push rod 506 is provided at the front end of the top of the box 502, and a second guide wheel 507 is provided at the bottom of the second electric push rod 506. The spray pipe 111 cooperates with the third guide wheel 603 and the second guide wheel 507. After passing through the third guide wheel 603, the spray pipe 111 is wound around the outer edge of the second guide wheel 507. A first electric push rod 503 is provided at the bottom front side of the box 502. 3. The first electric push rod 503 is connected to the front end of the box 502. The bottom of the first electric push rod 503 is provided with a right angle frame 504. The front end of the right angle frame 504 is provided with a guide block 505. The spray pipe 111 passes through the guide block 505. After being guided by the guide block 505, the spray pipe 111 cooperates with the winding roller 108 to complete the winding of the spray pipe 111. The top of the right angle frame 504 is connected to the bottom of the cleaning box 601. The first electric push rod 503, the second electric push rod 506 and the third electric push rod 602 can all be extended and retracted as needed to control the state of the spray pipe 111 inside the box 502 and complete the cleaning when the spray pipe 111 is wound up.

[0049] A cylindrical rod 702 is provided on the rear side of the spray ring 406. The cylindrical rod 702 is rotatably connected to the inclined rod 701. A passive telescopic rod 703 is provided on the rear side of the inclined rod 701. The bottom of the passive telescopic rod 703 is rotatably connected to the cleaning box 601. When the third electric push rod 602 retracts, it drives the third guide wheel 603 to move upward. The third guide wheel 603 drives the rear side of the spray pipe 111 to tilt upward. At this time, the bottom of the third electric push rod 602 can drive the inclined rod 701 to move upward. The inclined rod 701 drives the cylindrical rod 702 and the spray ring 406 to move upward synchronously. The cylindrical rod 702 pulls the passive telescopic rod 703 to extend. At the same time, due to the change in the position of the cylindrical rod 702, the corresponding passive telescopic rod 703 will... Figure 11 When rotated clockwise in the specified state, its top will rotate counterclockwise via the cylindrical rod 702 and the spray ring 406, thereby ensuring that the height and tilt angle of the spray ring 406 are parallel to the spray pipe 111, ensuring a proper rinsing angle.

[0050] A ball valve 604 is located at the bottom of the cleaning box 601, and a drain pipe 607 is located at the bottom of the ball valve 604, passing through the bottom of the box body 502. A first gear 605 is located at the rear end of the ball valve 604, and a rack 606 meshes with the outer side of the first gear 605. The rack 606 is fixedly connected to the box body 502. A first electric push rod 503 extends and drives the cleaning box 601 downward through a right-angle bracket 504. The cleaning box 601 drives the ball valve 604 downward, and under the action of the rack 606, it can drive the first gear 605 to rotate, thereby opening the ball valve 604 and discharging the sludge suspension at the bottom of the cleaning box 601 through the curved drain pipe 607. The discharge flow rate of the drain pipe 607 is slightly larger. The amount of liquid sprayed by the spray head 407 ensures that there is always a sufficient amount of liquid inside the cleaning box 601, and the sludge can be collected inside the cleaning box 601 without causing liquid to overflow. This facilitates the pre-soaking of the unrinsed spray pipe 111, thereby breaking up the clumps of dirt. Combined with subsequent rinsing, this ensures the cleaning effect of the spray pipe 111. The ball valve 604 has a large internal switching friction. During the descent, it can be opened in conjunction with the first gear 605 and the rack 606. As the ball valve 604 continues to descend, it remains open and will not close automatically. It will only be completely closed when the ball valve 604 returns to the top.

[0051] In use: During the unwinding stage, control the two take-up rollers 108 to rotate counterclockwise simultaneously to release the wound spray pipe 111. With manual pulling, the wound spray pipe 111 is extracted from inside the frame 101 for subsequent spraying operations. The rotation of the take-up rollers 108 drives the slider 204 to reciprocate, guiding the unwound spray pipe 111 and ensuring its orderly release during unwinding. Furthermore, the movement of the right-side box 502 also causes the piston plate 306 inside the rectangular cylinder 304 to move left and right. At this time, the telescopic plate 307 retracts, opening the internal through-hole of the piston plate 306 and removing the blockage. And the... Solenoid valve 308 and solenoid valve 309 are closed. This means that although piston plate 306 is reciprocating, no pressurized fluid is formed inside rectangular cylinder 304. In other words, the spray head 407 does not spray liquid in the unwinding state. At the same time, the third electric push rod 602 retracts and drives the third guide wheel 603 to rise, so that the third guide wheel 603 and the second guide wheel 507 are at the same height. This reduces the contact area between the surface of the spray pipe 111 and the second guide wheel 507 and the third guide wheel 603. The path of the spray pipe 111 becomes more direct, reducing the additional tension and possible additional friction caused by the height difference. As a result, the arrangement of the spray pipe 111 can be completed more easily.

[0052] After spraying, when it's time to wind up the spray pipe 111, since it's always in contact with the ground during use, it will accumulate soil or debris. Therefore, the surface of the spray pipe 111 needs to be cleaned to prevent affecting the winding effect and to prevent hard impurities from scratching its surface. At this point, the winding roller 108 is reversed to pull and wind up the spray pipe 111. As the winding roller 108 rotates, it moves the slider 204, which, through the right-side housing 502, moves the piston plate 306 left and right within the rectangular cylinder 304. Before winding, during the last leftward movement of the piston plate 306 within the rectangular cylinder 304, the telescopic plate 307 inside the piston plate 306 extends, sealing the through-hole of the piston plate 306. As the piston plate 306 moves to the left, the gas in the left-side cavity of the piston plate 306 is squeezed out through the one-way valve 401. Then, the piston plate 306 moves to the right... Figure 6 The state shown (this state was chosen for ease of understanding, but it may also be a similar state of piston plate 306 in other positions) means that at this time, the left cavity of piston plate 306 is under negative pressure. After the winding begins, the first solenoid valve 308 opens and the liquid inside water tank 301 is drawn into the left cavity of rectangular cylinder 304 under the action of negative pressure.

[0053] After winding begins, the piston plate 306 reciprocates inside the rectangular cylinder 304 to... Figure 6 Taking the state shown as an example, the piston plate 306 moves to the left, while the first solenoid valve 308 closes and the second solenoid valve 309 opens. The piston plate 306 pushes the liquid from the left cavity out of the rectangular cylinder 304, and then through the one-way valve 401 and the first hose 402 on the left into the liquid distribution box 403, and then delivers it to the interior of the two spray rings 406 respectively. During the process of the piston plate 306 moving to the left, since the second solenoid valve 309 is in the open state, the liquid in the water tank 301 can be drawn into the right cavity of the piston plate 306. When the piston plate 306 starts to move to the right again, the second solenoid valve 309 closes and the first solenoid valve 308 opens, so that the one-way valve 401 and the first hose 402 on the right can drain the liquid. Through the above state switching, when the spray pipe 111 is retracted, the spray head 407 can continuously spray liquid to clean the surface of the spray pipe 111 by relying on the drainage component.

[0054] When cleaning the spray pipe 111, the condition is as follows: Figure 9As shown, the spray pipe 111 passes sequentially through the third guide wheel 603, the second guide wheel 507, and the guide block 505. In the initial winding stage, because part of the spray pipe 111 is still inside the box 502 and the top of the box 502 has not yet touched the ground, its cleanliness is relatively high. Therefore, when the spray pipe 111 is rinsed by the spray head 407 in the initial winding stage, the liquid is relatively clean and free of impurities. After rinsing, the liquid accumulates inside the cleaning box 601. At this time, the ball valve 604 at the bottom of the cleaning box 601 is closed, and the clean liquid gathers inside the cleaning box 601. Initially, the liquid inside the cleaning box 601 is relatively low. At this time, the position of the third guide wheel 603 is relatively low, meaning that the spray pipe 111 passing through the third guide wheel 603 must first pass through... The third guide wheel 603 allows the spray pipe 111 to be soaked inside the cleaning box 601 first, dispersing any clumps of mud and sludge on its surface. Then, the liquid from the spray head 407 washes away the mud from the surface of the spray pipe 111. As the spray pipe 111 continues to retract, the amount of liquid inside the cleaning box 601 increases, and so do the impurities. At this point, the third electric push rod 602 is controlled to retract, raising the height of the third guide wheel 603 and the spray pipe 111. The mud and sludge inside the cleaning box 601 gradually settle, and the relatively clean liquid at the top continues to soak the spray pipe 111, achieving a secondary treatment of the spray pipe 111 and ensuring a good cleaning effect.

[0055] During the retraction of the third electric actuator 602, the inclined rod 701 can be moved upward. The inclined rod 701 drives the cylindrical rod 702 and the spray ring 406 to move upward synchronously. The cylindrical rod 702 pulls the passive telescopic rod 703 to extend. At the same time, due to the change in the position of the cylindrical rod 702, the corresponding passive telescopic rod 703 will... Figure 11 When rotated clockwise in the specified state, its top will rotate counterclockwise via the cylindrical rod 702 and the spray ring 406, thereby ensuring that the height and tilt angle of the spray ring 406 are parallel to the spray pipe 111, ensuring a proper rinsing angle.

[0056] As winding continues, a layer of spray pipe 111 will be wrapped around the surface of the winding roller 108. With the cooperation of the winding assembly, multiple layers of winding can continue. At the same time, the first electric push rod 503 is controlled to descend in stages. During the descent, the guide block 505 moves downward, thus ensuring that the tension on the entire spray pipe 111 does not increase during multi-layer winding. As the first electric push rod 503 extends, it can drive the cleaning box 601 to descend, and then fully open the ball valve 604 to suspend the impurities at the bottom of the cleaning box 601. The liquid is discharged through the drain pipe 607, and the discharge volume of the drain pipe 607 is slightly greater than that of the spray head 407. This ensures that there is always a large amount of liquid inside the cleaning box 601, and the sludge can be collected in the cleaning box 601, preventing the liquid from overflowing. This facilitates the pre-soaking of the unrinsed spray pipe 111, which can break up the clumps of mud. Combined with subsequent rinsing, this ensures the cleaning effect of the spray pipe 111. The first electric push rod 503 extends in stages to achieve multi-layer winding and sewage discharge operations.

[0057] It should be noted that: by controlling the two take-up rollers 108 to rotate counterclockwise simultaneously, in conjunction with manual pulling, and by guiding the unwinding spray pipe 111 through the reciprocating movement of the slider 204, the orderly release of the spray pipe 111 is ensured during the unwinding process. The telescopic plate 307 is in a retracted state, opening the internal through hole of the piston plate 306. The first solenoid valve 308 and the second solenoid valve 309 are closed. In the unwinding state, the spray head 407 does not spray liquid, and the third electric push rod 602 retracts, driving the third guide wheel 603 to rise. Positioned at the same height as the second guide wheel 507, this reduces the contact area between the surface of the spray pipe 111 and the guide wheel, minimizing additional tension and friction. During winding, the piston plate 306 reciprocates within the rectangular cylinder 304. By switching between the states of the first solenoid valve 308 and the second solenoid valve 309, liquid in the water tank 301 is drawn in and pushed out, continuously cleaning the surface of the spray pipe 111. The liquid inside the cleaning box 601 is initially relatively clean and used for initial rinsing. As winding progresses, the amount of liquid and impurities increases. By adjusting the height of the third guide wheel 603, sludge sedimentation is achieved. The cleaner liquid at the top is used to continue soaking the spray pipe 111. During the retraction of the third electric push rod 602, the inclined rod 701, cylindrical rod 702, and spray ring 406 move synchronously. Through the extension and rotation of the passive telescopic rod 703, the height and tilt angle of the spray ring 406 are ensured to be parallel to the spray pipe 111, ensuring a proper rinsing angle. The spray pipe 111 is treated twice through soaking and rinsing, ensuring effective cleaning. With the cooperation of the winding assembly, multi-layer winding is achieved. By controlling the staged extension of the first electric push rod 503, the tension on the spray pipe 111 does not increase during multi-layer winding, and the cleaning box 601 is lowered for sewage discharge. This ensures that there is always a large amount of liquid inside the cleaning box 601, and the sludge is collected inside the cleaning box 601. The liquid inside the cleaning box 601 will not overflow, ensuring smooth unwinding, effective cleaning, and efficient winding of the spray pipe 111 during use, improving the reliability and service life of the equipment.
