Description

Technical Field

[0001] This invention relates to the field of sanitation vehicle technology, specifically to a sweeping and sprinkling sanitation vehicle with garbage collection and disposal functions. Background Technology

[0002] Sanitation vehicles are specialized vehicles used for urban sanitation and cleaning. They typically include water sprinkler trucks, sweeper trucks, and garbage trucks. These functions, such as sweeping, watering, and garbage transportation, are all performed using separate vehicles. Common garbage sweeper trucks use two disc-shaped brushes to clean garbage. However, the sweeping distance of these disc brushes is limited. For wide roads, the garbage sweeper truck needs to sweep back and forth multiple times, resulting in slow cleaning speed and low efficiency. When the garbage sweeper truck sucks garbage into its interior, a large amount of dust is also sucked into the suction chamber and adheres to the filter screen. Over time, this reduces the garbage truck's ability to absorb waste, requiring frequent cleaning of the filter screen. Therefore, sanitation vehicles cannot perform long-term cleaning operations. Summary of the Invention

[0003] The purpose of this invention is to provide a sanitation vehicle that integrates sweeping and disposing of garbage, in order to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sanitation vehicle with integrated sweeping and dispensing functions for garbage collection and disposal, comprising a sanitation vehicle, wherein a pair of sweeping components are symmetrically arranged inside the sanitation vehicle, a brush strip is arranged below the sanitation vehicle and located between the pair of sweeping components, and a magnetic suction component is arranged below the rear of the sanitation vehicle. The sweeping components clean the road surface, the magnetic suction component removes metal objects from the road surface, and a dust suction component is arranged inside the sanitation vehicle. The dust suction component adsorbs garbage on the road surface and also sorts the adsorbed garbage.

[0005] Furthermore, each of the sweeping components includes a variable angle shaft and a bracket. The variable angle shaft is rotatably mounted inside the sanitation vehicle, and the bracket is rotatably positioned below the variable angle shaft. A coil spring is provided at the rotatable connection point between the bracket and the variable angle shaft. A dual-head motor is mounted on the bracket, and the dual-head motor is vertically positioned. A drive sprocket is provided at the lower end of the dual-head motor. A water spray pipe is also provided on the bracket. A driven sprocket is rotatably connected to the end of the water spray pipe away from the bracket. A chain is connected to the drive sprocket and the driven sprocket. A sweeping brush is provided on the outer side of each link of the chain. A water tank is provided inside the sanitation vehicle. The water tank is connected to the two water spray pipes through a hose. When the two dual-head motors are energized and rotate, the dual-head motors drive the drive sprocket to rotate. The drive sprocket drives the chain to move. The driven sprocket fixes the direction of the chain's movement. The movement of the chain causes the sweeping brushes to move simultaneously.

[0006] Furthermore, a friction wheel is installed at the upper end of the dual-head motor, and an inclined wheel is rotatably arranged at the position of the variable-angle shaft corresponding to the friction wheel. The inclined wheel contacts the friction wheel, and there is an angle between the rotation center axis of the inclined wheel and the rotation center axis of the friction wheel in space. When the dual-head motor rotates, it drives the friction wheel to rotate as well. The friction wheel drives the inclined wheel to rotate. Since the axes of the friction wheel and the inclined wheel are not parallel, there is an angle difference between the circumferential force of the friction wheel and the circumferential force of the inclined wheel. The inclined wheel is fixed, so the movement of the friction wheel is subject to additional resistance. After the resistance overcomes the elastic force of the coil spring, the bracket deflects on the variable-angle shaft, and finally deflects to a state where the axis of the friction wheel can be parallel to the axis of the inclined wheel. The deflection of the bracket causes the movement plane of the chain to tilt, and the sweeping brush on one side of the chain contacts the ground and begins to sweep the ground, sweeping the garbage on the ground towards the bottom of the sanitation vehicle. The garbage is sucked into the sanitation vehicle through the suction channel.

[0007] Furthermore, the sanitation vehicle is equipped with an electric push rod inside, on which a rack is connected. The rack has toothed grooves on both sides. Gears are positioned on the two variable-angle shafts corresponding to the rack, and both gears mesh with the rack for transmission. When the electric push rod is energized, it moves the rack, which in turn rotates the two gears through the toothed grooves. The two variable-angle shafts rotate relative to each other, causing several sweeping brushes to open outwards. When the dual-head motor stops working, the bracket resets under the action of a coil spring, preventing the sweeping brushes from contacting the ground and reducing wear on the brushes during normal vehicle operation. The chain-driven sweeping brushes extend to both sides of the sanitation vehicle under the action of the electric push rod. The degree of opening of the two sets of sweeping brushes is determined by the width of the road surface. Compared to traditional disc-type sweeping brushes, this allows the sanitation vehicle to sweep a larger area in one pass, resulting in faster cleaning speed and higher cleaning efficiency.

[0008] Furthermore, the magnetic suction assembly includes several flat pulleys, each connected to a flat belt. An electromagnet is installed around the inner circumference of the flat belt, and the electromagnet is mounted on the bottom of the sanitation vehicle. A drive wheel is connected to one of the flat pulley shafts, and the drive wheel contacts one of the sanitation vehicle's wheels. A storage box is installed at the rear of the sanitation vehicle. When the wheel rotates, it drives the drive wheel to rotate, which in turn drives the flat pulley to rotate via its shaft. When the electromagnet is energized, it generates magnetic force. If there are metal objects on the ground, they cannot be sucked into the sanitation vehicle through the suction channel. The metal objects are attracted to the flat belt as they pass under the electromagnet and move with it. When the metal objects move to a position where the electromagnet can no longer attract them, they fall into the storage box.

[0009] Furthermore, the sanitation vehicle has a suction channel inside, one end of which is located at the bottom of the sanitation vehicle near the brush strip. The suction assembly includes a servo motor and a fixed inner core. The rotating sleeve is mounted on the servo motor and fits over the fixed inner core. Several metal claws are slidably arranged on the rotating sleeve, and each metal claw has a small locking post at one end. Several curved grooves are opened on the fixed inner core, and the small locking posts are slidably arranged inside the curved grooves. The air pump draws gas from the suction chamber and sucks the garbage into the suction chamber through the suction channel. The servo motor drives the rotating sleeve to rotate, and the rotating sleeve drives the several metal claws to move. When the metal claws move, the small locking posts slide along the curved grooves, causing the metal claws to continuously retract and extend on the rotating sleeve. The most common items on the ground include leaves and dust. If there are plastic bags or paper in the garbage that is sucked up, the leaves and their dirt can easily pass through the gaps between the metal claws, while the plastic bags and paper are hooked by the metal claws and dragged in the opposite direction of the suction chamber.

[0010] Furthermore, the sanitation vehicle is equipped with a garbage compartment and two tracked wheels. One tracked wheel is located above the rotating housing, and the other tracked wheel is located in the garbage compartment. Tracks are mounted on both tracked wheels, and several rubber blocks are installed on the tracks. Felt is installed around the inner circumference of the tracks, and the felt contacts the tracks. A small pulley is connected to one side of the tracked wheel above the rotating housing. A large pulley is also mounted on the motor shaft of the servo motor. A V-belt connects the large pulley and the small pulley. The small pulley on the servo motor drives the large pulley to rotate via the V-belt. When a track wheel rotates, it drives the track to move. The rubber blocks on the track rub against the felt, accumulating negative charges on the rubber blocks. When a plastic bag or paper approaches the track, the metal claw has already retracted into the rotating housing. The track attracts the plastic bag or paper, carrying it into the waste chamber. Inside the waste chamber, there are exposed wires. One end of the exposed wire is in contact with the track, and the other end is grounded. When the rubber block comes into contact with the exposed wire, the charge on the rubber block is transferred, and the plastic bag or paper loses its charge attraction and falls into the waste chamber.

[0011] Furthermore, the sanitation vehicle is equipped with a dust collection chamber located on one side of the rotating housing. The dust collection assembly includes an air pump and an arc-shaped bracket. The arc-shaped bracket is located inside the dust collection chamber, and a filter cloth is stretched taut on the arc-shaped bracket. The air pump is located at the end of the arc-shaped bracket away from the rotating housing, and the air outlet of the air pump is connected to a water tank. The water tank is equipped with a pressure reducing valve. If dust adheres to the filter cloth, it will reduce the sanitation vehicle's ability to absorb garbage over time. Because the filter cloth is taut, when leaves are sucked into the dust collection chamber, they impact the filter cloth with the airflow, causing the filter cloth to vibrate and shake off the dust, thus enhancing the sanitation vehicle's absorption capacity during long-term cleaning operations. The air pump outputs gas to the water tank, increasing the air pressure in the water tank. The pressure reducing valve maintains the air pressure in the water tank at a fixed level. Water in the water tank is squeezed into the water spray pipe through two hoses and then sprayed out from the water spray pipe, realizing the function of cleaning and watering simultaneously.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] 1. By using an electric push rod to drive two variable-angle shafts to rotate relative to each other, several sweeping brushes are opened outwards. The sweeping brushes, driven by a chain, extend to both sides of the sanitation vehicle under the action of the electric push rod. The degree of opening of the two sets of sweeping brushes is adjusted according to the width of the road surface. Compared with traditional disc-type sweeping brushes, the sanitation vehicle can clean a larger area of ​​the road surface in one pass, making the sanitation vehicle sweeping faster and more efficient. When the dual-head motor stops working, the bracket returns to its original position under the action of the coil spring, and the sweeping brushes do not come into contact with the ground, reducing the wear of the sweeping brushes when the sanitation vehicle is in normal operation.

[0014] 2. By using metal claws to drag plastic bags and paper in the opposite direction of the dust collection chamber, preliminary sorting of leaves and household waste is carried out. If dust adheres to the filter cloth, it will reduce the garbage adsorption capacity of the sanitation vehicle over time. By setting the filter cloth to a taut state, when the leaves are sucked into the dust collection chamber, they hit the filter cloth with the airflow, causing the filter cloth to vibrate and shake off the dust, thereby enhancing the adsorption capacity of the sanitation vehicle during long-term cleaning operations.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0026] Please see Figures 1-8 The present invention provides a technical solution: a sanitation vehicle with integrated sweeping and disposing of garbage, comprising a sanitation vehicle 1, a pair of sweeping components symmetrically arranged inside the sanitation vehicle 1, a brush strip 14 arranged below the sanitation vehicle 1 between the pair of sweeping components, a magnetic suction component arranged below the rear of the sanitation vehicle 1, the sweeping components sweeping the road surface, the magnetic suction component cleaning metal objects on the road surface, and a dust suction component arranged inside the sanitation vehicle 1, the dust suction component adsorbing garbage on the road surface, and the dust suction component also classifying the adsorbed garbage.

[0027] The sanitation vehicle 1 is equipped with an electric push rod 12, on which a rack 13 is connected. The rack 13 has toothed grooves on both sides. Two variable angle shafts 2 are fitted with gears (not shown in the diagram) corresponding to the rack 13. Both gears mesh with the rack 13 for transmission. When the electric push rod 12 is energized, it moves the rack 13, which in turn drives the two gears to rotate through the toothed grooves. The two variable angle shafts 2 rotate relative to each other, causing several sweeping brushes 9 to open outwards. Each sweeping component includes a variable angle shaft 2 and a bracket 3. The variable angle shaft 2 is rotatably mounted inside the sanitation vehicle 1, and the bracket 3 is rotatably positioned below the variable angle shaft 2. The bracket 3 rotates with the variable angle shaft 2. A coil spring (not shown in the figure) is provided at the position of the moving connection. A dual-head motor 4 is installed on the bracket 3. The dual-head motor 4 is set vertically. A drive sprocket 6 is provided at the lower end of the dual-head motor 4. A water spray pipe 5 is also provided on the bracket 3. A driven sprocket 7 is rotatably connected to the end of the water spray pipe 5 away from the bracket 3. A chain 8 is connected to the drive sprocket 6 and the driven sprocket 7. A cleaning brush 9 is provided on the outer side of each link of the chain 8. When the two dual-head motors 4 are powered on, they rotate. The dual-head motors 4 drive the drive sprocket 6 to rotate. The drive sprocket 6 drives the chain 8 to move. The driven sprocket 7 fixes the direction of movement of the chain 8. The movement of the chain 8 causes the cleaning brush 9 to move at the same time.

[0028] A friction wheel 10 is mounted on the upper end of the dual-head motor 4. A slanted wheel 11 is rotatably mounted on the variable-angle shaft 2 at the position corresponding to the friction wheel 10. The slanted wheel 11 contacts the friction wheel 10. The rotation axis of the slanted wheel 11 and the rotation axis of the friction wheel 10 form an angle in space. As the dual-head motor 4 rotates, it drives the friction wheel 10 to rotate as well. The friction wheel 10 drives the slanted wheel 11 to rotate. Because the axes of the friction wheel 10 and the slanted wheel 11 are not parallel, there is a circumferential force on the rotation axis of the friction wheel 10 and a circumferential force on the rotation axis of the slanted wheel 11. The angle difference causes the inclined wheel 11 to remain stationary, resulting in additional resistance to the movement of the friction wheel 10. After the resistance overcomes the elastic force of the coil spring, the bracket 3 deflects on the variable angle shaft 2, eventually deflecting until the axis of the friction wheel 10 is parallel to the axis of the inclined wheel 11. The deflection of the bracket 3 causes the plane of movement of the chain 8 to tilt, and the sweeping brush 9 on one side of the chain 8 contacts the ground and begins to sweep the ground, sweeping the garbage on the ground towards the bottom of the sanitation vehicle 1. The garbage is sucked into the sanitation vehicle 1 through the suction channel 22.

[0029] The sanitation vehicle 1 is equipped with a water tank 19. The air outlet of the air pump 34 is connected to the water tank 19. The water tank 19 is equipped with a pressure reducing valve (not shown in the figure). The water tank 19 is connected to two water spray pipes 5 via hoses. The air pump 34 outputs air into the water tank 19, increasing the air pressure in the water tank 19. The pressure reducing valve maintains the air pressure in the water tank 19 at a fixed level. The water in the water tank 19 is forced into the water spray pipes 5 through the two hoses and then sprayed out from the water spray pipes 5, realizing simultaneous sweeping and watering. When the dual-head motor 4 stops working, the bracket 3 returns to its original position under the action of the coil spring, and the sweeping brush 9 does not come into contact with the ground, reducing the wear of the sweeping brush 9 when the sanitation vehicle 1 is driving normally. The sweeping brush 9 driven by the chain 8 extends to both sides of the sanitation vehicle 1 under the action of the electric push rod 12. The degree of opening of the two sets of sweeping brushes 9 is determined by the width of the road surface. Compared with the traditional disc-type sweeping brush 9, the sanitation vehicle 1 can sweep a larger area of ​​the road surface in one pass, making the sanitation vehicle 1 sweep faster and more efficiently.

[0030] The magnetic suction assembly includes several flat pulleys 17, with a flat belt 15 connected to each pulley 17. An electromagnet 16 is installed around the inner circumference of the flat belt 15. The electromagnet 16 is installed at the bottom of the sanitation vehicle 1. A drive wheel 18 is connected to the shaft of one of the flat pulleys 17. The drive wheel 18 is in contact with one of the wheels of the sanitation vehicle 1. A storage box is installed at the rear of the sanitation vehicle 1. When the wheel rotates, it drives the drive wheel 18 to rotate. The drive wheel 18 drives the flat pulley 17 to rotate through the shaft. When the electromagnet 16 is energized, it generates magnetic force. If there are metal objects on the ground, they cannot be sucked into the sanitation vehicle 1 through the suction channel 22. When the metal objects pass under the electromagnet 16, they are attracted to the flat belt 15 and move with the flat belt 15. When the metal objects move to a position where the electromagnet 16 can no longer attract them, the metal objects fall into the storage box.

[0031] The sanitation vehicle 1 has a suction channel 22 inside, with one end of the suction channel 22 located at the bottom of the sanitation vehicle 1 near the brush strip 14. The suction assembly includes a servo motor 23, a fixed inner core 28, and a rotating sleeve 27 mounted on the servo motor 23. The rotating sleeve 27 is fitted over the fixed inner core 28, and several metal claws 29 are slidably arranged on the rotating sleeve 27. Each metal claw 29 has a small locking post at one end. The fixed inner core 28 has several curved grooves, and the small locking posts are slidably arranged inside the curved grooves. The sanitation vehicle 1 contains garbage. The chamber 21 has two tracked wheels 30. One tracked wheel 30 is located above the rotating housing 27, and the other tracked wheel 30 is located in the garbage chamber 21. Tracks 31 are provided on the two tracked wheels 30. Several rubber blocks 32 are provided on the track 31. Felt 33 is provided on the inner circumference of the track 31 and the felt 33 is in contact with the track 31. A small pulley 25 is connected to one side of the tracked wheel 30 located above the rotating housing 27. A large pulley 24 is also provided on the motor shaft of the servo motor 23. A V-belt 26 is connected between the large pulley 24 and the small pulley 25.

[0032] Air pump 34 draws air from the suction chamber 20 and sucks the garbage into the suction chamber 20 through suction channel 22. Servo motor 23 drives rotating housing 27 to rotate, which in turn drives several metal claws 29 to move. As the metal claws 29 move, small pins slide along curved grooves, causing the metal claws 29 to continuously retract and extend on the rotating housing 27. The most common debris on the ground includes leaves and dust. If plastic bags or paper are present in the garbage being sucked up, the leaves and dust can easily pass through the gaps between the metal claws 29, while the plastic bags and paper are hooked by the metal claws 29, dragging them in the opposite direction of the suction chamber 20. The small pulley 25 on servo motor 23 is driven by V-belt 26. The large pulley 24 rotates, driving a track wheel 30 to rotate. The track wheel 30 drives the track 31 to move. The rubber block 32 on the track 31 rubs against the felt 33, accumulating negative charge on the rubber block 32. When the plastic bag or paper approaches the track 31, the metal claw 29 has already been retracted into the rotating housing 27. The track 31 attracts the plastic bag or paper, carrying it into the garbage chamber 21. The garbage chamber 21 has exposed wires inside. One end of the exposed wires is in contact with the track 31, and the other end is grounded. When the rubber block 32 contacts the exposed wires, the charge on the rubber block 32 is transferred, and the plastic bag or paper loses its charge attraction and falls into the garbage chamber 21.

[0033] The sanitation vehicle 1 is equipped with a dust collection chamber 20, which is located on one side of the rotating housing 27. The dust collection components include an air pump 34 and an arc-shaped bracket 35. The arc-shaped bracket 35 is located inside the dust collection chamber 20, and a filter cloth 36 is stretched taut on the arc-shaped bracket 35. The air pump 34 is located at the end of the arc-shaped bracket 35 away from the rotating housing 27. If dust adheres to the filter cloth 36, it will reduce the sanitation vehicle 1's ability to absorb garbage over time. Since the filter cloth 36 is in a taut state, when leaves are sucked into the dust collection chamber 20, they are impacted by the airflow and cause the filter cloth 36 to vibrate, which shakes the dust off the filter cloth 36 and enhances the sanitation vehicle 1's absorption capacity during long-term cleaning operations.

[0034] The working principle of this invention: When using the sanitation vehicle of this invention to sweep the road, the operator controls the electric push rod 12 to be energized, which drives the rack 13 to move. The rack 13 drives two gears to rotate through the tooth grooves, and the two variable angle shafts 2 rotate relative to each other, opening several sweeping brushes 9 outward. The two dual-head motors 4 are energized and rotate, driving the drive sprocket 6 to rotate. The drive sprocket 6 drives the chain 8 to move, and the driven sprocket 7 fixes the direction of movement of the chain 8. The movement of the chain 8 causes the sweeping brushes 9 to move simultaneously. The rotation of the dual-head motors 4 also drives the friction wheel 10 to rotate, which in turn drives the inclined wheel 11 to rotate. Due to friction... The axes of wheel 10 and inclined wheel 11 are not parallel. There is an angle difference between the circumferential force of the rotation of friction wheel 10 and the circumferential force of the rotation of inclined wheel 11. The inclined wheel 11 is fixed, which makes the movement of friction wheel 10 subject to additional resistance. After the resistance overcomes the elastic force of the coil spring, the bracket 3 deflects on the variable angle shaft 2. Finally, it deflects to the state where the axis of friction wheel 10 can be parallel to the axis of inclined wheel 11. The deflection of bracket 3 causes the plane of movement of chain 8 to tilt. The sweeping brush 9 on one side of chain 8 contacts the ground and begins to sweep the ground, sweeping the garbage on the ground towards the bottom of sanitation vehicle 1. The garbage is sucked into sanitation vehicle 1 through suction channel 22.

[0035] Air pump 34 outputs gas to water tank 19, increasing the air pressure in water tank 19. Pressure reducing valve maintains the air pressure in water tank 19 at a fixed level. Water in water tank 19 is squeezed into water spray pipe 5 through two hoses and then sprayed out from water spray pipe 5, realizing the function of sweeping and watering at the same time. When the dual-head motor 4 stops working, bracket 3 returns to its original position under the action of coil spring, and sweeping brush 9 does not contact the ground, reducing the wear of sweeping brush 9 when the sanitation vehicle 1 is driving normally. The sweeping brush 9 driven by chain 8 extends to both sides of sanitation vehicle 1 under the action of electric push rod 12. The degree of opening of the two sets of sweeping brush 9 is determined by the width of the road surface. Compared with the traditional disc sweeping brush 9, the sanitation vehicle 1 sweeps a larger area of ​​the road surface in one pass, making the sanitation vehicle 1 sweep faster and more efficiently.

[0036] When the wheel rotates, it drives the drive wheel 18 to rotate. The drive wheel 18 drives a flat pulley 17 to rotate through the shaft. When the electromagnet 16 is energized, it generates magnetic force. If there are metal objects on the ground, they cannot be sucked into the sanitation vehicle 1 through the dust suction channel 22. When the metal objects pass under the electromagnet 16, they are attracted to the flat belt 15 and move with the flat belt 15. When the metal objects move to a position where the electromagnet 16 can no longer attract them, the metal objects fall into the storage box.

[0037] Air pump 34 draws air from the suction chamber 20 and sucks the garbage into the suction chamber 20 through the suction channel 22. Servo motor 23 drives rotating housing 27 to rotate, which in turn drives several metal claws 29 to move. As the metal claws 29 move, small pins slide along curved grooves, causing the metal claws 29 to continuously retract and extend on the rotating housing 27. The most common debris on the ground includes leaves and dust. If plastic bags or paper are present in the garbage being sucked up, the leaves and their dust can easily pass through the gaps between the metal claws 29, while the plastic bags and paper are hooked by the metal claws 29, dragging them in the opposite direction of the suction chamber 20. The small pulley 25 on servo motor 23 drives the large pulley 24 to rotate via V-belt 26. The large pulley 24 drives a track wheel 30 to rotate, which in turn drives the track 31 to move. The rubber blocks 32 and felt 3 on the track 31 move together. 3. Friction occurs, and negative charges accumulate on the rubber block 32. When the plastic bag or paper approaches the track 31, the metal claw 29 has already been retracted into the rotating housing 27. The track 31 adsorbs the plastic bag or paper and carries it into the garbage chamber 21. The garbage chamber 21 has exposed wires inside. One end of the exposed wires is in contact with the track 31, and the other end is grounded. When the rubber block 32 contacts the exposed wires, the charge on the rubber block 32 is transferred, and the plastic bag or paper loses the attraction of the charge and falls into the garbage chamber 21. If dust adheres to the filter cloth 36, it will reduce the garbage adsorption capacity of the sanitation vehicle 1 over time. Since the filter cloth 36 is in a taut state, when leaves are sucked into the dust suction chamber 20, they hit the filter cloth 36 with the airflow, causing the filter cloth 36 to vibrate and shake off the dust on the filter cloth 36, thereby enhancing the adsorption capacity of the sanitation vehicle 1 during long-term cleaning operations.
