[0034] In this embodiment, when the detection sensor 27 detects sharp debris, the adjustment mechanism works, and while adjusting the height of the cleaning bucket 4, the height of the collection box 5 in the assembly box 3 is also adjusted to ensure that the collection box 5 and the cleaning bucket 4 are in the best state. The air inlet end of the collection box 5 is connected to the cleaning bucket 4 through the conduit 6, and after the height is adjusted, it is ensured that the connection is not affected; the first motor 10 is started, and the first motor 10 drives the first bevel gear 11 fixed thereon to rotate, and drives the rotating rod 8 to rotate through the two first bevel gears 11 that transmit to each other. The fan blades 9 fixedly installed on the rotating rod 8 rotate accordingly, generating suction, and the debris cleaned by the cleaning bucket 4 is sucked into the collection box 5 through the guide tube 6; the debris sucked into the collection box 5 falls into the receiving box 7 arranged in the collection box 5, completing the collection of the debris; the first motor 10 drives the fan blades 9 to rotate to generate suction, which can effectively absorb the debris cleaned by the cleaning bucket 4 into the collection box 5, which is more efficient than other collection methods, ensuring that the road debris can be collected in time; the height of the collection box 5 is adjustable, and it can be flexibly adjusted with the cleaning bucket 4 according to different cleaning needs and the driving status of the vehicle.

After the collection is completed, it is convenient to take out the receiving box 7 for cleaning. The operation is simple and convenient, which improves the convenience of vehicle maintenance; the collection mechanism realizes the efficient collection of road debris through the coordinated work of components such as the collecting box 5, the guide tube 6, the rotating rod 8, the fan blades 9, the first motor 10, the first bevel gear 11 and the receiving box 7. It has the advantages of efficient collection, flexible cooperation and convenient cleaning, and further enhances the ability of the intelligent chassis of the outdoor delivery electric vehicle to cope with complex road environments.

[0035] In a further preferred embodiment of the present invention, the adjusting mechanism: a first screw 12 rotatably installed in the collecting box 5 through a bearing; an adjusting plate 13 threadedly sleeved on the first screw 12, the adjusting plate 13 being fixedly connected to the collecting box 5; a first guide rod 14 fixedly installed in the collecting box 5, the first guide rod 14 passing through the adjusting plate 13 for limiting and guiding the same; a second motor 31 installed on the collecting box 5 through a mounting shell 30 for driving the first screw 12 to rotate, the output shaft of the second motor 31 being fixedly connected to the first screw 12 via a coupling.

[0036] In this embodiment, when the height of the collection box 5 needs to be adjusted, the second motor 31 installed on the collection box 5 starts to work. The output shaft of the second motor 31 is fixedly connected to the first screw 12 through a coupling, so the operation of the second motor 31 can drive the first screw 12 to rotate; when the first screw 12 rotates, the adjustment plate 13 threadedly sleeved thereon cannot rotate with the first screw 12 due to the limiting and guiding effect of the first guide rod 14 that penetrates through it, and can only move along the axial direction of the first screw 12. The adjusting plate 13 is fixedly connected to the collecting box 5, so the movement of the adjusting plate 13 drives the collecting box 5 to achieve height adjustment; by controlling the rotation direction and number of rotations of the second motor 31, the rotation of the first screw 12 can be accurately controlled, and then the height of the collecting box 5 can be accurately adjusted, so that the cooperation with the cleaning bucket 4 can reach the best state to meet different road conditions and cleaning requirements; the method of using the second motor 31 to drive the first screw 12 to rotate can accurately control the lifting height of the collecting box 5. Compared with the traditional adjustment method, it has higher accuracy and can be accurately adjusted according to actual conditions to ensure efficient cleaning and collection work; the first guide rod 14 passes through the adjusting plate 1 3 is used for limiting and guiding. During the adjustment process, the stability of the movement of the adjustment plate 13 and the collection box 5 is ensured to avoid shaking or offset, making the entire adjustment process more reliable and extending the service life of the equipment; the entire adjustment process is driven by the second motor 31, which is simple and convenient to operate. It can be remotely controlled or automatically adjusted according to a preset program through an automated control system, thereby improving the intelligence level and operation convenience of the intelligent chassis of the outdoor delivery electric vehicle; the adjustment mechanism of this patent realizes the precise and stable adjustment of the height of the collection box 5 through the coordinated operation of the first screw 12, the adjustment plate 13, the first guide rod 14, the second motor 31 and other components. It has the advantages of precise control, stability and reliability, and easy operation. In conjunction with the collection mechanism and the cleaning bucket 4, it further enhances the ability of the intelligent chassis of the outdoor delivery electric vehicle to adapt to complex road environments and improves the overall performance.

[0037] In a further preferred embodiment of the present invention, a mesh cover 15 is fixedly installed in the collection box 5 by bolts, and the mesh cover 15 is used to protect the fan blades 9. A connecting sleeve 16 is assembled on the rotating rod 8, and a cleaning brush 17 for cleaning the mesh cover 15 is fixedly installed on the connecting sleeve 16.

[0038] In this embodiment, before the collection mechanism is operated, the mesh cover 15 has been fixedly installed in the collection box 5 by bolts, and its position is in front of the fan blades 9. When the fan blades 9 rotate with the rotating rod 8 to absorb debris, the mesh cover 15 protects the fan blades 9 and prevents debris from directly hitting the fan blades 9; during the rotation of the rotating rod 8, the connecting sleeve 16 mounted on the rotating rod 8 rotates synchronously, and the cleaning brush 17 fixedly installed on the connecting sleeve 16 also rotates together. The cleaning brush 17 continuously cleans the mesh cover 15 during the rotation process, cleans up the debris attached to the mesh cover 15, and makes it fall into the receiving box 7; the setting of the mesh cover 15 effectively prevents sharp debris from directly hitting the fan blades 9, avoids the fan blades 9 from being damaged when rotating at high speed, prolongs the service life of the fan blades 9, ensures the continuous and stable operation of the collection mechanism, and reduces the maintenance cost of the equipment; the cleaning brush 17 can automatically clean the mesh cover 15 to prevent debris from accumulating and blocking the mesh holes of the mesh cover 15, ensures the smooth air intake of the collection box 5, maintains the stability of the suction generated by the rotation of the fan blades 9, and then Ensure the efficient collection of debris; the cleaning brush 17 automatically cleans the mesh cover 15 along with the rotating rod 8, and there is no need to frequently disassemble and clean the mesh cover manually, which saves labor costs and improves the degree of automation and ease of use of the equipment; through the arrangement of the mesh cover 15 and the cleaning brush 17, while protecting the fan blades 9, the mesh cover 15 is kept unobstructed, and no manual cleaning is required, which further improves the function of the collection mechanism, and cooperates with other components such as the adjustment mechanism to enhance the ability of the outdoor delivery electric vehicle intelligent chassis to cope with complex road conditions, thereby improving the overall practicality and reliability.

[0039] In a further preferred embodiment of the present invention, a water tank 18 is fixedly installed on the top of the assembly box 3, and the water tank 18 is used to hold water to settle dust. The air outlet end of the collection box 5 is fixedly connected to a telescopic tube 19, and the air outlet end of the telescopic tube 19 extends into the water tank 18.

[0040] In this embodiment, before the outdoor delivery electric vehicle intelligent chassis is activated, the water tank 18 is first fixedly installed on the top of the assembly box 3, and then a sufficient amount of water is injected into the water tank 18 to prepare for the subsequent dust settling; when the collection mechanism is running, the collection box 5 sucks in the debris, and the internal airflow flows out from the air outlet. Since the air outlet of the collection box 5 is fixedly connected to the telescopic tube 19, the airflow flows along the telescopic tube 19. The telescopic tube 19 can be extended or contracted according to the height adjustment of the collecting box 5 to ensure that the air outlet is always in the water tank 18, so that the airflow can smoothly enter the water in the water tank 18; introducing the dust-containing airflow discharged from the collecting box 5 into the water in the water tank 18 can effectively absorb the dust and tiny particles in the airflow to prevent these pollutants from being discharged into the atmosphere, thereby reducing pollution to the surrounding environment, ensuring the clean air in the distribution area, and reducing the impact of dust on pedestrians, residents and surrounding facilities; the telescopic characteristics of the telescopic tube 19 allow it to maintain a firm connection with the water tank 18 when the height of the collecting box 5 changes, ensuring the stable operation of the entire dust settling system and avoiding airflow leakage or functional failure due to loose connection; the combination of the water tank 18 and the telescopic tube 19 adds an air purification function on the basis of the original debris cleaning and collection functions of the chassis, making the equipment functions more diversified, improving the applicability and practicality of the chassis in complex environments, and meeting the needs of more practical application scenarios.

[0041] In a further preferred embodiment of the present invention, a sewage pipe 21 for discharging sewage when changing water is fixedly installed on one side of the water tank 18, and a water valve 22 for controlling the on-off of the pipeline is provided on the sewage pipe 21.

[0042] In this embodiment, during the process of continuous dust settling in the water tank 18, the operator needs to regularly check the turbidity of the water in the water tank. When it is found that there are too many impurities in the water, which affects the dust settling effect, it is necessary to change the water; after determining to change the water, find the sewage pipe 21 fixedly installed on one side of the water tank 18, and the sewage pipe 21 is provided with a water valve 22 for controlling the on-off of the pipeline. Open the water valve 22, and the sewage containing a large amount of dust and impurities in the water tank 18 will be discharged along the sewage pipe 21 under the action of gravity; after the sewage in the water tank 18 is discharged, close the water valve 22, and then clean the water tank and refill it with water, so that the water tank 18 can continue to be put into use and maintain the purification function of the airflow discharged from the collection mechanism; the setting of the sewage pipe 21 and the water valve 22 makes the water tank 18 water change and sewage discharge operation simple and convenient. Without the need for complicated steps such as manually scooping water or disassembling the water tank, the operator only needs to easily open and close the water valve 22 to complete the sewage discharge, which greatly saves the time and labor costs of water replacement; timely discharge of turbid sewage in the water tank 18 and water replacement can ensure that the water in the water tank always maintains good dust adsorption capacity, thereby ensuring the purification effect of the dust-laden airflow discharged from the collection box 5, and continuously providing clean protection for the operation of the equipment and the surrounding environment; regular sewage discharge and water replacement through the sewage pipe 21 can avoid excessive accumulation of impurities in the water tank 18 causing corrosion or blockage of the equipment, effectively extending the service life of the water tank 18 and related components of the entire dust sedimentation system, and reducing equipment maintenance and replacement costs.

[0043] In a further preferred embodiment of the present invention, a connecting frame 28 is fixedly installed on the front of the assembly box 3 by bolts, and an anti-collision shell 29 is fixedly installed on the connecting frame 28. The anti-collision shell 29 is a hollow structure that can absorb energy when impacted.

[0044] In this embodiment, before the outdoor delivery electric vehicle intelligent chassis is put into use, the connecting frame 28 is fixedly installed on the front of the assembly box 3 by bolts to ensure a stable connection. Then, the anti-collision shell 29 is fixedly installed on the connecting frame 28 so that it is at a suitable position at the front end of the vehicle; when the vehicle is driving, once the front end encounters a collision, the first thing to be exposed to the impact force is the anti-collision shell 29. Since the anti-collision shell 29 is a hollow structure, the impact force will cause it to deform. During this deformation process, the anti-collision shell 29 absorbs the impact energy and reduces the impact force transmitted to the assembly box 3 and other key components of the vehicle; the anti-collision shell 29 can effectively absorb the impact energy, greatly reducing the damage to the assembly box 3 and the internal equipment of the vehicle caused by the collision, protecting the core components of the vehicle, and reducing equipment failures and maintenance costs caused by collisions; by absorbing energy to reduce the impact force of the collision, the degree of damage to the vehicle during a collision is reduced, the risk of safety accidents caused by collisions is reduced, the safety of cargo transportation is reduced, and the safety of outdoor delivery electric vehicles in complex road conditions is also improved; the connecting frame 28 is fixedly installed on the front of the assembly box 3 with bolts, and the installation and disassembly processes are relatively simple, which is convenient for replacing the anti-collision shell 29 after it is damaged, thereby improving the convenience of equipment maintenance.

[0045] In a further preferred embodiment of the present invention, a crushing roller 26 for crushing debris is rotatably installed in the assembly box 3 through a bearing, and a first gear 32 for transmission is fixedly installed on the shaft of the crushing roller 26, and two adjacent first gears 32 are meshed with each other for transmission.

[0046] In this embodiment, the crushing roller 26 is rotatably mounted in the assembly box 3 through the bearing to ensure that it can rotate flexibly. At the same time, the first gear 32 for transmission is fixedly mounted on the shaft of the crushing roller 26, so that two adjacent first gears 32 are meshed with each other, completing the construction of the transmission structure; when the collecting mechanism sucks the ground debris into the assembly box 3, the shaft of one of the crushing rollers 26 is driven to rotate by the driving source, and the first gear 32 on the shaft rotates accordingly. Since the adjacent first gears 32 are meshed with each other, they will drive the other first gears 32 meshed with them to rotate, thereby causing multiple crushing rollers 26 to rotate synchronously. During the rotation, the debris is transported between the crushing rollers 26, and is crushed and crushed by the high-speed rotating crushing rollers 26; the crushing rollers 26 crush the sucked debris and break the larger volume of debris into small pieces, effectively reducing the space occupied by the debris, so that the collection box 5 can accommodate more debris, improve the collection efficiency, and reduce the number of cleaning times; after the debris is crushed, large pieces of debris are prevented from clogging the collection mechanism or the conveying pipeline, ensuring the smooth operation of the entire cleaning and collection system, reducing the probability of equipment failure due to clogging, and improving the stability and reliability of the equipment.

[0047] In a further preferred embodiment of the present invention, a detachable box cover 20 is provided on the water tank 18, a handle for grasping is fixedly installed on the top of the box cover 20, an exhaust pipe for pressure relief is fixedly connected to the top of the box cover 20, and an inspection door 51 is fixedly installed on one side of the assembly box 3 through a hinge, and a door lock is provided on the inspection door 51.

[0048] In this embodiment, when the water tank 18 needs to be cleaned, water quality tested, or chemicals are added to enhance dust settling effect, the operator firmly grasps the handle on the top of the tank cover 20 and removes the tank cover 20 from the water tank 18 by pulling it upward. In this process, the handle provides a stable gripping point for easy exertion; when the water tank 18 is working normally, the pressure inside may increase due to gas generation or temperature changes. When the pressure reaches a certain level, the gas will be discharged through the exhaust pipe fixedly connected to the top of the box cover 20, realizing automatic pressure relief, ensuring that the internal pressure of the water tank 18 is always within a safe range; after completing the maintenance work, align the box cover 20 with the opening of the water tank 18, gently put it down and ensure that it is well sealed to ensure the normal function of the water tank 18; when it is necessary to inspect, repair or replace parts of the equipment in the assembly box 3, such as the collection mechanism, adjustment mechanism, crushing roller 26, etc., first use the key to open the door lock on the inspection door 51, and then use the hinge as the axis to rotate outward to open the inspection door 51, so as to obtain the operating space for the equipment inside the assembly box 3; in the non-maintenance state, close the inspection door 51 and lock the door lock to prevent foreign objects from entering the interior of the assembly box 3, and at the same time avoid people from accidentally touching the internal running parts to ensure the safe operation of the equipment.

[0049] In a further preferred embodiment of the present invention, the cleaning bucket 4 is provided with a through opening 23 for accommodating an electromagnet 24, and the electromagnet 24 can be upgraded and adjusted to absorb metal debris passing through the cleaning bucket 4. The cleaning bucket 4 is also provided with a collection box 25 with a movable and adjustable position, and the collection box 25 is used to block the through opening 23 and receive and collect metal debris falling from the demagnetized electromagnet 24.

[0050] In this embodiment, before the cleaning bucket 4 works, it is ensured that the electromagnet 24 is installed at the opening 23 of the cleaning bucket 4. When the vehicle is running, the cleaning bucket 4 starts to clean the debris on the ground. When metal debris passes by, the magnetic force of the electromagnet 24, which is initially in the opening 23 and powered on, attracts the metal debris; when the sharp impurities on the road surface are cleaned, the electromagnet 24 is regulated to rise and then the electromagnet 24 is powered off and demagnetized to make the metal debris fall off. When the electromagnet 24 rises, the position of the collecting box 25 is adjusted to change accordingly, and it moves to the top of the opening 23. The collecting box 25 can not only block the opening 23, but also receive the metal debris dropped from the demagnetized electromagnet 24.

[0051] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0052] In another embodiment of the present invention, the cleaning bucket 4 is provided with a driving mechanism for driving the crushing roller 26, and the driving mechanism includes: a first transmission rod 33 rotatably mounted on the cleaning bucket 4 through a bearing seat; two second bevel teeth 34 for transmission that are respectively fixedly mounted on the shaft of the crushing roller 26 and the first transmission rod 33 and are meshed with each other; and first pulleys 35 that are respectively fixedly mounted on the first transmission rod 33 and the rotating rod 8, and the two first pulleys 35 are sleeved with the same first timing belt 36 for rotation.

[0053] In this embodiment, the first transmission rod 33 is rotatably mounted on the cleaning bucket 4 through the bearing seat to ensure that it can rotate flexibly. The second bevel teeth 34 that mesh with each other are fixedly mounted on the shaft of the crushing roller 26 and the first transmission rod 33, respectively, and the first belt pulley 35 is fixedly mounted on the first transmission rod 33 and the rotating rod 8, respectively, and the same first timing belt 36 is sleeved on the two first belt pulleys 35 to complete the installation and connection of the entire driving mechanism; when the rotating rod 8 of the collecting mechanism starts to rotate, the first belt pulley 35 on the rotating rod 8 rotates accordingly, and the first belt pulley 35 on the first transmission rod 33 is driven to rotate through the first timing belt 36, thereby rotating the first transmission rod 33. When the first transmission rod 33 rotates, the second bevel teeth 34 thereon also rotate synchronously. Since the second bevel teeth 34 mesh with each other, the second bevel teeth 34 on the shaft of the crushing roller 26 are driven to rotate, and then the crushing roller 26 starts to rotate to crush the sucked debris. The power of the rotating rod 8 can be efficiently transmitted to the crushing roller 26 by utilizing the transmission of the first pulley 35 and the first timing belt 36, as well as the meshing transmission of the second bevel teeth 34, to ensure that the crushing roller 26 obtains a stable power source and improves the efficiency of debris crushing. The crushing roller 26 is driven by the power of the rotating rod 8, and there is no need to set up an independent drive motor for the crushing roller 26, which effectively reduces the energy consumption of the equipment, reduces energy costs, and improves energy utilization efficiency.

[0054] In another embodiment of the present invention, the cleaning bucket 4 and the assembly box 3 are provided with a linkage adjustment mechanism for regulating the upgrading of the electromagnet 24 and the movement of the collection box 25, and the linkage adjustment mechanism includes: an assembly frame 37 fixedly mounted on the cleaning bucket 4, a second screw 38 is rotatably mounted on the assembly frame 37 through a bearing, an adjustment frame 39 is threadedly sleeved on the second screw 38, and the bottom end of the adjustment frame 39 is fixedly connected to the electromagnet 24; a second guide rod 42 fixedly mounted on the assembly frame 37, the second guide rod 42 passes through the adjustment frame 39 for limiting and guiding it; a rack plate 43 fixedly mounted in the assembly box 3; a second transmission rod rotatably mounted on the assembly frame 37 through a bearing 44, a second gear 45 is fixedly installed at one end of the second transmission rod 44, and the second gear 45 is meshed with the rack plate 43; the second transmission rod 44 and the second screw 38 are fixedly installed with third bevel teeth 46 that mesh with each other for transmission; a third screw 47 rotatably installed on the third screw 47 through a bearing seat, a mounting plate 48 is threadedly sleeved on the third screw 47, and the mounting plate 48 is fixedly connected to the collection box 25; a third guide rod 49 for guiding is arranged on the mounting plate 48, and both ends of the third guide rod 49 are fixedly connected to the cleaning bucket 4; two fourth bevel teeth 50 that are respectively fixedly installed on the second screw 38 and the third screw 47 and mesh with each other for transmission.

[0055] In this embodiment, the height of the electromagnet 24 and the position of the collecting box 25 will change with the height of the cleaning bucket 4, and the second screw 38 will rotate during the descent of the cleaning bucket 4. The second screw 38 rotates through the bearing on the assembly frame 37. Since the second guide rod 42 penetrates the adjustment frame 39 to play a limiting and guiding role, the adjustment frame 39 will not rotate with the second screw 38, but move along the axial direction of the second screw 38. The bottom end of the adjustment frame 39 is fixedly connected to the electromagnet 24, so the movement of the adjustment frame 39 drives the electromagnet 24 to achieve height adjustment, and can enter and exit the opening 23; while adjusting the height of the electromagnet 24, the second screw 38 rotates to drive the fourth bevel gear 50 thereon to rotate, and another fourth bevel gear 50 meshing with it rotates accordingly, thereby driving the third screw 47 to rotate. The mounting plate 48 threadedly sleeved on the third screw 47 moves axially along the third screw 47 under the guidance of the third guide rod 49, and the mounting plate 48 is fixedly connected to the collection box 25, so as to realize the position adjustment of the collection box 25; the second gear 45 at one end of the second transmission rod 44 meshes with the rack plate 43 fixed in the assembly box 3, and when the cleaning bucket 4 and the assembly box 3 are regulated to rise and fall, the second gear 45 moves along the rack plate 43, driving the second transmission rod 44 to rotate. The second transmission rod 44 meshes with the third bevel gear 46 on the second screw 38, so that the rotation of the second transmission rod 44 is transmitted to the second screw 38, so as to realize the linkage adjustment of the electromagnet 24 and the collection box 25. Through the linkage adjustment mechanism, the height of the electromagnet 24 and the position of the collection box 25 can be accurately adjusted, and the actions of the two cooperate with each other to ensure that the positions are always matched when the metal debris is adsorbed and collected, thereby improving the accuracy and efficiency of the collection of metal debris; the entire linkage adjustment mechanism is composed of multiple components working together, and the components are closely matched, the structure is compact, and the space occupied is small. At the same time, the provision of the second guide rod 42 and the third guide rod 49 ensures the stability of the adjustment process and avoids shaking or deviation.

[0056] In another embodiment of the present invention, a first trigger switch 40 for controlling the demagnetization of the electromagnet 24 is fixedly installed on the assembly frame 37, a top rod 41 for resisting the opening of the first trigger switch 40 is fixedly installed on the adjustment frame 39, and a main controller 60 is provided on the inspection door 51. The main controller 60 is adapted to the detection sensor 27 and is used to regulate the start and stop of the first motor 10 and the second motor 31.

[0057] In this embodiment, after the electromagnet 24 absorbs the metal debris, when the adjustment frame 39 rotates and rises to a certain position with the second screw 38, the top rod 41 fixedly installed on the adjustment frame 39 will contact the first trigger switch 40 fixedly installed on the assembly frame 37. The contact action of the top rod 41 will trigger the first trigger switch 40, so that it sends a demagnetization signal to the electromagnet 24, thereby achieving the demagnetization of the electromagnet 24, allowing the absorbed metal debris to fall into the collection box 25; the detection sensor 27 detects the road debris in real time, and when it detects sharp debris in front, it transmits the signal to the main controller 60 set on the inspection door 51. After receiving the signal, the main controller 60 controls the first motor 10 to start according to the preset program, drives the fan blade 9 to rotate, and opens the collection mechanism; at the same time, it controls the second motor 31 to start, adjusts the height of the collection box 5 and the cleaning bucket 4 to meet different debris cleaning and collection needs. When the debris is cleared and the detection sensor 27 does not detect any debris, a signal is sent to the main controller 60, and the main controller 60 controls the first motor 10 and the second motor 31 to stop running; through the cooperation of the top rod 41 and the first trigger switch 40, the automatic control of the demagnetization of the electromagnet 24 is realized. When the electromagnet 24 rises to a suitable position, the demagnetization is automatically triggered, and no manual intervention is required, and the falling time of metal debris is accurately controlled, thereby improving the collection efficiency and accuracy; the main controller 60 is adapted to the detection sensor 27, and can intelligently control the start and stop of the first motor 10 and the second motor 31 according to the road debris detection situation. The collection mechanism and the adjustment mechanism only work when there are debris to be cleaned, avoiding unnecessary energy consumption, improving the operation efficiency of the equipment, and reducing the energy consumption cost; the setting of the top rod 41, the first trigger switch 40 and the main controller 60 further improves the automation level of the intelligent chassis of the outdoor delivery electric vehicle. It reduces the manual operation links, reduces the impact of human factors on the operation of the equipment, and enables the equipment to operate more stably and reliably.

[0058] In another embodiment of the present invention, the cleaning bucket 4 is provided with an anti-blocking emergency stop mechanism, which includes: a cylinder 52 fixedly connected to the cleaning bucket 4, a mesh plate 53 is provided on the cylinder 52, and a second trigger switch 54 for regulating the stop of the first motor 10 is provided on the mesh plate 53; a piston plate 55 arranged in the cylinder 52 and capable of being raised and lowered for triggering the second trigger switch 54; a fourth screw rod 56 slidably mounted on the cylinder 52, and the bottom end of the fourth screw rod 56 is fixedly connected to the piston plate 55; a spring 57 sleeved on the fourth screw rod 56, and a nut 58 threadedly sleeved on the fourth screw rod 56 for pre-tightening the spring 57; and a limit block 59 fixedly mounted in the cylinder 52 for limiting the position of the piston plate 55.

[0059] In this embodiment, when the cleaning bucket 4 is cleaning debris normally, the first motor 10 drives the fan blade 9 to rotate, generating suction to absorb debris. At this time, the piston plate 55 is in a normal position in the cylinder 52, and the spring 57 is in a natural state or is moderately pre-tightened by the nut 58. Since there is no blockage, the second trigger switch 54 on the mesh plate 53 is not triggered, and the first motor 10 continues to operate; when the cleaning bucket 4 is blocked, the debris cannot pass smoothly, causing the air pressure in the cylinder to change. The change in air pressure pushes the piston plate 55 to move upward, and the piston plate 55 rises in the cylinder 52, and its top contacts and triggers the second trigger switch 54 on the mesh plate 53. After the second trigger switch 54 is triggered, a signal is immediately sent to stop the first motor 10 from working to prevent motor damage or other more serious faults caused by blockage; after cleaning the blockage, the emergency stop mechanism needs to be restored to the initial state. The operator rotates the fourth screw 56 to move the piston plate 55 downward and return to the initial position. At the same time, the nut 58 can be adjusted according to the actual situation, and the spring 57 can be further pre-tightened or loosened to adapt to different working environments and blockage risks. During the descent of the piston plate 55, the limit block 59 limits it to ensure that the piston plate 55 does not drop excessively; through the coordinated work of the cylinder 52, the mesh plate 53, the second trigger switch 54, the piston plate 55, the fourth screw 56, the spring 57, the nut 58 and the limit block 59, etc., the blockage of the cleaning bucket 4 is effectively monitored and responded to in time, which has the advantages of effectively protecting equipment, preventing serious failures and flexible adjustment and strong adaptability.

[0060] To sum up, compared with the relevant technology, through the cooperation of the detection sensor 27, the cleaning bucket 4, the collecting mechanism and the adjusting mechanism, the tire puncture can be effectively avoided, the distribution efficiency can be improved and the cost can be reduced, the vehicle safety can be guaranteed, the collecting mechanism can efficiently collect debris, the adjusting mechanism can accurately control the height of the collecting box 5, the mesh cover 15 and the cleaning brush 17 can protect the fan 9 blades and maintain smooth air intake, the water tank 18 and the telescopic tube 19 can purify the air, the drain pipe 21 and the water valve 22 can facilitate the maintenance of the water tank 18, the anti-collision shell 29 can protect the core components, the crushing roller can prevent the blockage of debris, the various linkage adjusting mechanisms and the trigger control devices can improve the automation and accuracy, and the emergency stop mechanism can protect the equipment; on the whole, the device realizes efficient, safe and stable distribution operations under complex road conditions, and improves the practicality, reliability and intelligence level of the equipment.
