Description

Technical Field

[0001] This invention relates to the field of garbage cleaning, and more particularly to a reciprocating cleaning device, a cleaning vehicle, and a cleaning method. Background Technology

[0002] With urban development, construction waste trucks frequently operate on roads in the urban-rural fringe areas. Some soil, sand, and gravel are scattered and crushed by the vehicles, easily hardening on the road surface. Existing sweepers use a sweeping disc that is placed in a fixed position and then lowered. The sweeping disc rotates, and the polyethylene brush rubs against the ground to clean up the hardened material.

[0003] However, existing sweeping discs can only clean a fixed area after being deployed, resulting in a small cleaning range and low cleaning efficiency. Furthermore, the polyethylene brushes are relatively soft, and when the sweeping disc rotates, the contact between the compacted material and the ground is not firm, and because the compacted material is higher than the ground, the relative distance between the sweeping disc and the compacted material is small. The brushes are easily deformed by the compacted material, and they are also unable to remove compacted debris from the road surface, resulting in poor cleaning effect. Based on the above technical problems, there is an urgent need to provide a reciprocating sweeping device, sweeper, and sweeping method. Summary of the Invention

[0004] The purpose of this invention is to provide a reciprocating sweeping device, a sweeping vehicle, and a sweeping method.

The lifting device is movably mounted on the mounting frame and the cleaning device at both ends, respectively, and is used to drive the cleaning device to swing up and down. A distance measuring sensor is installed on the cleaning device and electrically connected to the control module. The control module is configured with a set threshold for the distance to be detected by the distance measuring sensor. When the distance between the mounting bracket and the distance measuring sensor is less than the set threshold, the distance measuring sensor sends a detection signal to the control module. The control module is used to control the start and stop of the sweeping device and the lifting device. In addition, the control module also sends an extension command to the lifting device according to the detection signal. The lifting device executes the extension command and extends to drive the metal brush on the sweeping device to descend.

The cleaning device is rotatably mounted on the second hinge seat. The lifting device is movably mounted on one end of the mounting frame and is mounted on the lower long rod via a hanging ring. The swing device is movably mounted on one end of the mounting frame and is hinged to the lower long rod via a pin.

[0008] Optionally, the second hinge seat is rotatably mounted on the first hinge seat via a first pin, the first pin being vertically arranged, and the second hinge seat rotating about the first pin in the vertical direction; the cleaning device is rotatably mounted on the second hinge seat via a second pin, the second pin being horizontally arranged, and the cleaning device rotating about the second pin in the horizontal direction. A limiting block is provided on the first hinge seat, and a limiting screw is provided on the second hinge seat. One end of the limiting screw faces the limiting block, and the limiting block and the limiting screw are used to limit the rotation angle of the first hinge seat.

[0009] Optionally, the ranging sensor is mounted on a sensor mounting plate, which is located at the end of the cleaning device near the second hinge seat.

[0010] Optionally, the cleaning device further includes a sweeping disc, a sweeping disc seat, and a connecting rod. The metal brush is mounted on the sweeping disc, the sweeping disc is mounted on the sweeping disc seat, the sweeping disc seat is mounted on the mounting frame via the connecting rod, one end of the connecting rod is hinged to the sweeping disc seat, and the other end is hinged to the mounting frame. The connecting rod is provided with a hinge plate, and the hinge plate is provided with a plurality of adjustment holes, which are used to adjust the hinge position of the lifting device; The lifting device is movably mounted on one end of the cleaning device and hinged to one of the adjustment holes by a pin. The swing device is movably mounted on one end of the cleaning device and is mounted on the hinge plate via a first chain.

[0011] Optionally, an adjusting rod is provided between the mounting frame and the sweeping disc seat. The adjusting rod is a telescopic structure, with one end hinged to the mounting frame and the other end hinged to the sweeping disc seat, for adjusting the tilt angle of the sweeping disc seat.

[0012] Optionally, a stabilizing member is provided between the connecting rod and the mounting frame. Both ends of the stabilizing member are provided with hanging rings. One end of the hanging ring is hinged to the mounting frame by a pin, and the other end of the hanging ring is hinged to the adjustment hole on the hinge plate by a pin. The stabilizing element includes a second chain and a spring, with one end of the second chain connected to one end of the spring. The second chain is located at the end near the mounting bracket, and the spring is located at the end near the connecting rod.

[0013] Secondly, the present invention provides a sweeper vehicle, including a vehicle body, on which a standard sweeping device, a standard suction cup device and the reciprocating sweeping device described in the first aspect are installed. The reciprocating sweeping device is installed at the head of the vehicle body, the standard sweeping device is installed on both sides of the vehicle body, and the standard suction cup device is installed at the rear bottom of the vehicle body.

[0014] Thirdly, the present invention provides a reciprocating cleaning method, wherein during the movement of a sweeper, a reciprocating cleaning device on it implements the reciprocating cleaning method, comprising the following steps: Start the reciprocating cleaning device; The outward swing device extends, driving the sweeping device to swing outward; The lifting device extends until the ranging sensor outputs no detection signal, at which point the lifting device stops extending and the sweeping device is driven to descend.

When the external swing device resets, when the ranging sensor sends a detection signal to the control module, the control module controls the lifting device to drive the sweeping device to descend. The metal brush on the sweeping device descends to apply contact pressure to the ground debris until the ranging sensor no longer sends a detection signal to the control module, at which point the extension of the lifting device stops.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. The reciprocating cleaning device provided by this invention uses a metal brush on the cleaning device to contact the debris on the ground, applying pressure to the debris. During cleaning, the metal brush effectively lifts the debris off the ground. The cleaning angle of the cleaning device can be adjusted by driving the cleaning device to swing up and down through a lifting device. A distance sensor is installed on the cleaning device, and the detection signal output by the distance sensor controls the operation of the lifting device. When the debris on the ground has a certain height, the metal brush on the cleaning device is raised by the debris, thus raising the entire cleaning device. The lifting device can then be driven to further lower the cleaning device, increasing the pressure of the metal brush on the debris for cleaning and improving cleaning efficiency.

[0016] 2. The reciprocating cleaning device provided by the present invention is equipped with an external swing device, which drives the cleaning device to swing left and right, thereby expanding the cleaning range and improving the cleaning efficiency. Attached Figure Description

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] At least one embodiment provides a reciprocating cleaning device 1, including a mounting frame 2, a cleaning device 3, a lifting device 5, a distance sensor 37, and a control module. The cleaning device 3 includes a metal brush 31 that contacts and applies pressure to the hardened material on the ground. The lifting device 5 is movably mounted on the mounting frame 2 and the cleaning device 3 at both ends, driving the cleaning device 3 to swing up and down. The control module is electrically connected to the distance sensor 37, the cleaning device 3, and the lifting device 5, controlling their start and stop. The distance sensor 37 is mounted on the cleaning device 3, located near the mounting frame 2, and detects the distance between itself and the mounting frame 2 to determine the degree of the sweeping device 3's up-and-down swing, thereby controlling the operation of the lifting device 5.

[0023] Specifically, the control module is equipped with a distance sensor 37 that detects a set threshold for the distance. When the distance between the distance sensor 37 and the mounting bracket 2 is less than the set threshold, the distance sensor 37 sends a detection signal to the control module. Upon receiving the detection signal from the distance sensor 37, the control module sends an extension command to the lifting device 5. The lifting device 5 executes the extension command, extends, and drives the cleaning device 3 and its metal brush 31 to descend. The metal brush 31 further contacts the debris on the ground or increases the contact pressure on the debris, thus cleaning the debris on the ground more effectively.

[0024] The reciprocating cleaning device 1 provided in this embodiment drives the cleaning device 3 to swing up and down via the lifting device 5, thereby causing the metal brush 31 on it to swing up and down. The metal brush 31, made of metal material, is more effective at cleaning debris on the floor. In use, the lifting device 4 drives the cleaning device 3 to descend, causing the metal brush 31 on the cleaning device 3 to descend and contact the debris on the floor, applying pressure to it. When the debris on the floor has a certain height, the metal brush 31 is raised by the debris, so that the distance detected by the distance sensor 37 on the end of the cleaning device 3 near the mounting frame 2 is less than a set threshold. The distance sensor 37 sends a detection signal to the control module, and the control module controls the lifting device 5 to continue descending, further reducing the height of the metal brush 31, thereby ensuring that the metal brush 31 has a certain pressure on the debris on the floor, and better cleaning the debris.

[0025] At least one embodiment provides a reciprocating cleaning device 1 based on the above embodiments. An external swing device 6 is further provided on the mounting frame 2 and the cleaning device 3. The external swing device drives the cleaning device 3 to swing left and right. One end of the external swing device 6 is movably mounted on the mounting frame 2, and the other end is movably mounted on the cleaning device 3. Through the lifting device 5 and the external swing device 6, the cleaning device 3 can swing in all directions, both vertically and horizontally. In this embodiment, the lifting device 5 and the external swing device 6 are telescopic structures; for example, a telescopic hydraulic cylinder or an electric telescopic device can be used.

[0026] like Figure 1 , Figure 11 As shown, in this embodiment, the reciprocating sweeping device 1 is installed on the sweeper 8. There are two sweeping devices 3, which are symmetrically arranged about the central axis of the sweeper 8. By swinging the two sweeping devices 3 inward and outward, the garbage is pushed to the middle of the garbage truck. The garbage is then absorbed into the sweeper 8 by the suction cup at the bottom of the sweeper 8.

[0027] like Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 As shown, the specific structure of the mounting frame 2 is as follows: the mounting frame 2 includes a fixed frame 26 and a hinge frame 2. The fixed frame 26 includes two horizontally arranged long rods 261 and a vertical rod 262 installed on one of the long rods 261. The two long rods 261 are installed horizontally and vertically at intervals on the lower part of the front of the sweeper 8. The vertical rod 262 is installed on the lower long rod 261. The hinge frame 2 is installed on the vertical rod 262 by bolts.

[0028] In this embodiment, to enable the cleaning device 3 to swing up and down and left and right under the drive of the lifting device 5 and the swinging device 6, the hinge frame 2 includes a first hinge seat 22 and a second hinge seat 24. The second hinge seat 24 is rotatably mounted on the first hinge seat 22 via a first pin 23. The second hinge seat 24 can rotate around the first pin 23, enabling the second hinge seat 24 and its components to swing left and right. The cleaning device 3 is rotatably mounted on the second hinge seat 24 via a second pin 25. The cleaning device 3 can rotate around the second pin 25, enabling the cleaning device 3 and its components to swing up and down. The first hinge seat 22 includes a base plate 221 and a bracket 222. Two brackets 222 are provided, and the two brackets 222 are installed on the front side of the base plate 221 and are arranged vertically at intervals. The rear side of the base plate 221 is fixedly connected to the vertical rod 262 by bolts. Two brackets 222 have aligned pin holes, and the two ends of the first pin 23 are respectively fixedly installed in the pin holes of the two brackets 222. The second hinge seat 24 includes a base plate 241, brackets 242 and brackets 243. There are two brackets 242, which are installed on the base plate 241 with a left-right interval. The two brackets 242 have aligned pin holes, which are clearance-fitted with the first pin 23, so that the second hinge seat 24 and its components can rotate around the first pin 23. There are three brackets 243. Two brackets 243 are arranged with a left-right interval and are located below the base plate 241. The two brackets 243 have aligned pin holes, and the two ends of the second pin 25 are respectively installed in the pin holes of the two brackets 243. The third bracket 243 is located above the base plate and also has a pin hole.

[0029] like Figure 1 , Figure 3 As shown, in this embodiment, limiting blocks 223 are installed on both sides of the base plate 221, and a limiting screw 224 is installed on the base plate 241. One end of the limiting screw 224 faces the limiting block 223. The limiting block 223 and the limiting screw 224 limit the angle of rotation of the base plate 241 around the first screw, so as to prevent the sweeping device 3 on it from swinging inward at too large an angle and colliding with the sweeping device 3 next to it, and to prevent the sweeping device 3 from swinging outward at too large an angle and colliding with other facilities on the road and damaging the sweeping device 3.

[0030] like Figure 2 , Figure 5As shown, the cleaning device 3 includes a metal brush 31, a sweeping disc 32, a sweeping disc base 33, a base plate 34, and a connecting rod 35. The sweeping disc base 33 has an L-shaped structure. One horizontal end of the sweeping disc base 33 is connected to the sweeping disc 32 by bolts, and the other vertical end is mounted on the base plate 34. Three brackets 341 are provided on the base plate 34. Two brackets 341 are spaced apart and installed at the lower part of the base plate 34, while the third bracket 341 is installed at the upper part of the base plate 34. Each of the three brackets 341 has a pin hole. One end of the connecting rod 35 is rotatably mounted on two horizontally aligned brackets 343 on the base plate 241 via a second pin 25, and the other end is rotatably mounted on two horizontally aligned brackets 341 on the base plate 34 via a pin. A metal brush 31 is installed on the sweeping disc 32. The metal brush 31 is made of metal. When the metal brush 31 contacts the ground, it can apply greater contact pressure to the ground, thus making it easier to sweep up the hardened garbage on the ground.

[0031] like Figure 2 , Figure 3 As shown, in some embodiments, to more thoroughly clean debris from the road surface, an adjusting rod 4 is provided between the sweeping disc 32 and the hinge frame 21. This adjusting rod allows for adjustment of the tilt angle of the sweeping disc 32 relative to the ground. Specifically, the adjusting rod 4 is installed between the second base plate 241 and the third base plate 34. One end of the adjusting rod 4 is hinged to the third bracket 243 above the second base plate 241 via a pin, and the other end is hinged to the fourth bracket 341 above the third base plate 34 via a pin. The adjustable structure of the adjusting rod 4 is a conventional mechanism and will not be described in detail in this embodiment. For example, the adjusting rod 4 can adopt a two- or more-layer sleeve structure or a screw structure with internal and external threads. The adjusting rod 4 is manually adjusted, and the tilt angle of the third base plate 34 and its components relative to the ground is adjusted by adjusting the length of the adjusting rod 4, thus adapting to different cleaning environments. For example, as the length of the adjusting rod 4 increases, the angle between the sweeping disc 32 on the base plate 34 and the ground increases. After the lifting device 5 extends, the sweeping disc 32 is driven to descend, and the pressure of the front end of the metal brush 31 on the sweeping disc 32 on the ground increases, making the cleaning of the debris on the ground panel more thorough.

[0032] like Figure 1 , Figure 3 , Figure 4 , Figure 6As shown, in some embodiments, the metal brush 31 can continue to be used even when it wears out. The mounting point between the lifting device 5 and the cleaning device 3 is adjustable. To ensure the stability of the up-and-down swing, an adjusting rod 4 and a stabilizing member 7 are provided between the cleaning device 3 and the mounting frame 2. Specifically, a hinge plate 36 is installed in the middle of the connecting rod 35. The hinge plate 36 has an L-shaped structure, and both the lifting device 5 and the outward swing device 6 are movably mounted on the hinge plate 36. A plurality of adjusting holes 361 are provided on the hinge plate 36. The adjusting holes 361 include a plurality of adjusting holes 361 for adjusting the mounting point of the lifting device 5 and a plurality of adjusting holes 361 for adjusting the mounting point of the stabilizing member 7. The plurality of adjusting holes 361 for adjusting the lifting device 5 are arranged horizontally at intervals at the lower position of the hinge plate 36, and the plurality of adjusting holes 361 for adjusting the stabilizing member 7 are arranged vertically at intervals at the upper position of the hinge plate 36. One end of the lifting device 5 is hinged to one of the adjustment holes 361 via a pin, and the other end is mounted on the long rod 261 of the mounting frame 2 via a hanging ring 71, located on the lower of the two long rods 261. The stabilizing member 7 is hinged to one of the adjustment holes 361 via a pin. Both ends of the stabilizing member 7 are provided with hanging rings 71; one hanging ring 71 is connected to the adjustment hole 361 via a pin, and the other hanging ring 71 is mounted on the long rod 261 of the mounting frame 2, located on the upper of the two long rods 261. The stabilizing member 7 includes a second chain 73 and a spring 72, with one end of the second chain 73 and one end of the spring 72 mounted via the hanging ring 71. When the cleaning device 3 swings up and down, the spring 72 pulls it up, improving the stability of the cleaning device 3 and preventing it from shaking during the swing.

[0033] The control module also has a set value for the working torque of the metal brush. When the metal brush rotates, the output value of the motor torque on it is compared with the set value. When the output value is less than the set value, the control block determines that the metal brush is worn. Specifically, after the metal brush 31 is worn, the contact pressure of the metal brush 31 with the ground decreases, the frictional resistance between the metal brush 31 and the ground decreases when the metal brush 31 rotates, and the cleaning effect deteriorates. At this time, the motor torque value for rotating the metal brush 31 is less than the set value. The control module determines that the metal brush 31 is worn. After receiving the feedback of the wear of the metal brush 31, the control module adjusts the installation point position of the lifting device 5 until the lifting device 5 extends. The contact pressure between the metal brush 31 and the ground is restored to the factory setting, and the cleaning effect can be restored. The metal brush 31 can be completely used up before being scrapped.

[0034] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4One end of the external swing device 6 is hinged to a long rod 261 on the mounting frame 2 via a pin, and is located on the lower of the two long rods 261. The other end is bolted to a hanging ring 71 on the hinge plate 36 via a first chain 61. Specifically, the end of the external swing device 6 is connected to the end of the first chain 61 via a pin, and the other end of the first chain 61 is mounted on the hanging ring 71 bolt via a pin. The hanging ring 71 bolt is mounted on the lower part of the hinge plate 36. The external swing device 6 is connected to the hinge plate 36 via the first chain 61, realizing a soft connection between the external swing device 6 and the hinge plate 36, which can adapt and adjust when driving the sweeping device 3 to swing left and right. Furthermore, the chain connection can buffer the impact force during swinging, preventing the external swing device 6 from being damaged by excessive impact force. Meanwhile, the lifting device 5 is connected to the long rod 261 via the hanging ring 71. When the lifting device 5 moves, the hanging ring 71 and the long rod 261 can be finely adjusted in the front, back, left and right directions to adapt to the position and posture of the lifting device 5 and buffer the impact force during swinging.

[0035] In this embodiment, to ensure that the metal brush 31 can contact the ground for cleaning, a distance sensor 37 is installed at the end of the connecting rod 35 that is hinged to the base plate 241. The distance sensor 37 is mounted on a sensor mounting plate 371, which is mounted on the end of the connecting rod 35. The detection end of the distance sensor 37 faces the base plate 241, detecting the distance between the distance sensor 37 and the base plate 241. When the lifting device 5 extends and drives the cleaning device 3 to fall, the distance sensor 37 rotates downward with the connecting rod 35, increasing the distance between the distance sensor 37 and the base plate 241. The ground contact pressure of the metal brush 31 is set at the factory, the distance between the distance sensor 37 and the base plate 241 is set, and the set threshold of the distance sensor 37 is set. When the road surface is covered with a normal amount of garbage, after the sweeping device 3 swings outward and falls, the metal brush 31 is slightly raised by the garbage, and the distance between the distance sensor 37 and the base plate 241 is relatively large. Under this condition, the distance sensor 37 cannot detect a signal, and the sweeping device 3 performs the sweeping operation. When there is a lot of garbage on the road surface, after the sweeping device 3 swings outward and falls, the brush is raised by the garbage, and the distance between the distance sensor 37 and the base plate 241 is reduced. The distance sensor 37 detects a signal and feeds it back to the control module. The control module then controls the lifting device 5 to work, so that the height of the sweeping device 3 is lowered, increasing the contact pressure of the metal brush 31 with the ground.

[0036] In this embodiment, the cleaning device 3, lifting device 5, swing device 6, and distance sensor 37 are all connected to the control module. The control module controls the rotation of the metal brush 31 in the cleaning device 3, the extension and retraction of the lifting device 5, and the extension and retraction of the swing device 6. The distance detected by the distance sensor 37 between the cleaning device 3 and the base plate 241 is sent to the control module for judgment. When the judgment distance is less than a set threshold, an extension command is sent to the lifting device 5 to drive the lifting device 5 to extend. The control module includes a programmable controller, which sets the working program to execute the above working steps.

[0037] At least one embodiment also provides a sweeper 8, such as Figure 10 , Figure 11 As shown, the sweeper includes a vehicle body and the reciprocating sweeping device 1 described in the above embodiments. The reciprocating sweeping device 1 is installed in the middle of the front of the vehicle body, and is installed low. Standard sweeping devices 9 are also installed on the bottom sides of the vehicle body. The standard sweeping devices 9 clean up the garbage on both sides of the vehicle body. Standard suction devices 10 are also installed in the middle of the bottom of the vehicle body. The standard suction devices 10 suck the garbage cleaned by the reciprocating sweeping device 1 and the standard sweeping device 9 into the sweeper vehicle 8.

[0038] In this embodiment, the standard cleaning device 9 and the standard suction cup device 10 are existing technologies, and their specific structures will not be described in detail here.

[0039] At least one embodiment also provides a reciprocating cleaning method, implemented using the sweeper 8 described in the above embodiments, such as... Figure 9 As shown, when the reciprocating sweeping device 1 on the front of the vehicle is not in operation, the two sweeping devices 3 are in a parallel state and located in the middle of the front of the sweeper vehicle 8. After the reciprocating sweeping device 1 is turned on, a reciprocating sweeping method is implemented, including the following steps: like Figure 9 As shown in Figure B, the outward swing device 6 extends outward, driving the cleaning device 3 to swing outward; The lifting device 5 extends until the ranging sensor 37 outputs no detection signal. The lifting device 5 then stops extending and drives the sweeping device 3 to fall, so that the metal brush 31 on the sweeping device 3 contacts the ground and applies contact pressure to the garbage on the ground. Start the cleaning device 3, and the metal brush 31 begins to rotate; The external swing device 6 is reset, driving the sweeping device 3 to retract inward; the rotating metal brush 31 sweeps the garbage to the middle of the sweeper 8, and the garbage is sucked into the sweeper 8 by the standard suction cup device 10 at the bottom of the sweeper 8.

[0040] The lifting device 5 resets, driving the sweeping device 3 to lift upwards; Continue executing the steps of extending the swing device 6, extending the lifting device 5, resetting the swing device 6, and resetting the lifting device 5 in sequence to clean up the debris on the ground. Sweep the debris to the middle of the vehicle body, and after the sweeper 8 moves forward a certain distance, it is sucked into the sweeper 8 by the standard suction cup device 10 at the bottom of the vehicle body.

[0041] When the outward swing device 6 resets, the ranging sensor 37 outputs a detection signal, which is then sent to the control module. The control module controls the lifting device 5 to continue extending, and the metal brush on the sweeping device descends to apply contact pressure to the accumulated debris on the ground until the ranging sensor 37 outputs no detection signal, at which point the extension of the lifting device 5 stops. This ensures that the metal brush 31 on the sweeping device 3 applies sufficient contact pressure to the debris, effectively cleaning up the hardened debris on the ground.

[0042] During the above process, the standard cleaning device 9 is activated, and the standard cleaning device 9 sweeps the garbage on both sides of the vehicle body to the middle of the vehicle body, and sucks it into the sweeper vehicle 8 through the standard suction cup device 10.

[0043] like Figure 9 As shown in Figure C, after the reciprocating cleaning device 1 is turned on, it implements a cyclic cleaning mode of swinging outward, lowering, lifting, and retracting inward. The shaded area in the figure shows the cleaning area of ​​one cycle operation. The cleaning area is large, which improves the cleaning effect.

[0044] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
