[0033] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0034] Embodiment 1

[0035] Reference Figure 1-9 As shown, an adaptive transverse suction nozzle for a washing and sweeping vehicle comprises:

[0036] A lifting frame 1 is installed on the bottom side of a corresponding vehicle body, and the vehicle body is a washing and sweeping vehicle body;

[0037] The sliding frame 2 is connected to the lifting frame 1 in a transverse sliding manner and is driven by a transverse driving device 4 to move horizontally to the left and right. In this embodiment, the transverse driving device 4 is a differential oil cylinder. In other embodiments, the transverse driving device 4 can also be set as other existing driving devices.

[0038] The nozzle mechanism 3 includes a nozzle shell 31 connected to the sliding frame 2 at the top and open at the bottom, and a partition member 33 that is driven by an adjustable driving device 32 to move laterally in the nozzle shell 31. Specifically, the partition member 33 is a partition plate, and the partition member 33 divides the inner cavity of the nozzle shell 31 into two left and right suction chambers 311. The two suction chambers 311 are connected to the garbage bin 5 and the suction device of the vehicle body through a connecting component 34, and an opening and closing device 35 is provided on the connecting component 34. A garbage identification device 36 for detecting the position of garbage is provided at the front of the nozzle shell 31. The cavity 311 is provided with a plurality of left detection devices 312 and a plurality of right detection devices 313 for detecting the amount of garbage in the two suction cavities 311, respectively. The transverse drive device 4 drives the sliding frame 2 to drive the suction nozzle housing 31 to transversely move to correspond to the garbage on the side of the road ahead according to the detection feedback of the garbage identification device 36. The adjustment drive device 32 drives the barrier member 33 to move toward the side with a larger amount of garbage according to the comparison result of the amount of garbage in the two suction cavities 311 detected by the left detection device 312 and the right detection device 313, thereby compressing the space of the suction cavity 311 on the side with a larger amount of garbage. Specifically, in this embodiment, the left detection device 312 and the right detection device 313 can be set as infrared sensors, and the suction device can be set as a fan, etc., and each device is connected to the control system for communication.

[0039] The above-mentioned structure can drive the suction nozzle shell 31 to move horizontally to the back of the garbage through the sliding frame 2 when the garbage is piled up on the side of the road, so that the suction chamber 311 can suck up the garbage close to the edge to avoid residual garbage on the road surface; when the amount of garbage on one side is large, the barrier member 33 moves slowly toward the side with large garbage volume to gather the garbage on the side with large garbage volume, and reduce the ineffective airflow at the top of the suction chamber 311 on the side with large garbage volume, increase the suction force of the suction chamber 311 on the side with large garbage volume, quickly suck up the garbage, and thus improve the efficiency of cleaning garbage on the road surface; when the garbage is all on one side, the opening and closing device 3 of the garbage-free side is opened. The connecting assembly 34 on the garbage-free side is closed to stop the negative pressure suction operation of the suction chamber 311 on the garbage-free side, thereby avoiding power waste and saving energy and protecting the environment. At the same time, the drive device 32 is adjusted to drive the barrier member 33 to move slowly toward the garbage side, so that the garbage on the garbage side can be gathered by the movement of the barrier member 33, and the ineffective airflow at the top of the suction chamber 311 on the garbage side can be reduced, and the suction force of the suction chamber 311 on the garbage side can be increased to quickly suck and pick up the garbage, which not only improves the efficiency of cleaning the road garbage, but also avoids the generation of useless work, reduces the driving power of the suction device, reduces energy consumption, and saves energy and protects the environment.

The left detection device 312 and the right detection device 313 are symmetrically disposed side by side at the front of the side walls on the far side of the two suction chambers 311, so that the left detection device 312 and the right detection device 313 are disposed in front and the two suction cylinders 341 are disposed in the back. After receiving the detection signal, the control system controls the movement and adjustment time of the barrier member 33, so that when the vehicle body moves to the point where the two suction chambers 311 reach above the garbage, the barrier member 33 has moved and adjusted the suction on both sides, and the garbage on the side with a large amount of garbage or the side with garbage is directly sucked into the suction cylinder 341 by the large suction force and enters the garbage bin 5 through the suction pipe 342. The structural design is reasonable, which improves the control smoothness and makes the movement and adjustment of the barrier member 33 timely. The left and right outer walls of the suction nozzle shell 31 are symmetrically provided with sensing devices 314 for sensing the curb, thereby avoiding the suction nozzle shell 31 from colliding with the curb and being damaged, improving the stability of the suction nozzle mechanism 3 during operation and extending its service life. Specifically, in this embodiment, the opening and closing device 35 includes a cover plate 351 which is rotatably arranged in the trash bin 5 and rotatably covers the end of the suction pipe 342 away from the suction cylinder. The cover plate 351 is driven by the opening and closing cylinder 352 to open or close the suction cylinder. The sensing device 314 is set as a proximity switch. In other embodiments, the opening and closing device 35 can also be set as other types of existing devices, such as an opening and closing valve, etc., and the sensing device 314 can also be set as other existing sensing devices such as infrared sensors.

[0043] In order to facilitate the disassembly and assembly of the sliding frame 2, a plurality of vertically extending oval-shaped adjustment holes 242 are provided on one side of the angle plate 24 close to the connecting seat 23. The angle plate 24 is screwed through the adjustment holes 242 and then locked to the connecting seat 23. The spacing between the upper slider 211 and the lower slider 241 can be adjusted in height by the screws and the adjustment holes 242. Thus, the sliding frame 2 can be adjusted according to the vertical thickness gap of the slide rail square tube 111, which facilitates the disassembly and assembly of the sliding frame 2.

Specifically, the lifting drive device 61 is configured as a lifting cylinder, so that after the operation of the suction nozzle mechanism 3 is completed, the lifting frame 1 can be lifted by a number of lifting drive devices 61, thereby driving the sliding frame 2 and the suction nozzle mechanism 3 to rise and be stored at the bottom of the chassis beam 7. At the same time, during the lifting process, the lifting of the lifting frame 1 is limited by two limit rods 72 to improve the lifting stability of the lifting frame 1.

[0045] In order to improve the recognition range of the garbage identification device 36 and avoid missing garbage, the garbage identification device 36 is provided with two and symmetrically arranged on the left and right sides of the suction nozzle shell 31. The garbage identification device 36 on the right side includes a rotating seat 361 mounted on the front side of the top of the suction nozzle shell 31 and can rotate, a swing rod 362 with one end connected to the rotating seat 361 and the other end first extending to the right and then extending obliquely to the rear side, a visual device 363 vertically inserted and fixed on the other end of the swing rod 362, a swing driving device 364 with one end rotatably connected to the top of the suction nozzle shell 31 and a telescopic end rotatably connected to the rear part of the rotating seat 361, a limiting spring 365 is connected between the other end of the swing rod 362 and the right front part of the rotating seat 361, and the swing driving device 364 is used to drive the rotating seat 361 to rotate and drive the swing rod 362 to swing, so as to drive the visual device 363 to scan left and right to detect the garbage position in front of the suction nozzle shell 31.

[0047] A control method for an adaptive transverse suction nozzle for a washing and sweeping vehicle as described above comprises the following steps:

[0048] S1, during the movement of the cleaning and sweeping vehicle, the swing driving device 364 drives the rotating seat 361 to rotate and drive the swing rod 362 to swing, so that the visual device 363 scans left and right to detect the garbage position in front of the suction nozzle shell 31. When it is detected that the garbage position is located on the curb side, the transverse driving device 4 drives the sliding frame 2 to move transversely according to the detection feedback of the visual device 363, until the suction nozzle shell 31 corresponds to the back of the garbage and stops, the two opening and closing devices 35 are opened, and the two suction chambers 311 start negative pressure suction operation; therefore, when the garbage is accumulated on the curb side, the suction nozzle shell 31 can be driven by the sliding frame 2 to move transversely to the back of the garbage, so that the suction chamber 311 can suck up the garbage close to the edge to avoid residual garbage on the road surface;

[0049] S2, during the negative pressure suction operation of the two suction chambers 311, the garbage amounts in the two suction chambers 311 detected by the left detection device 312 and the right detection device 313 are compared; when the amount of garbage on one side is large, the adjustment driving device 32 drives the baffle 33 to slowly move toward the side with large garbage amount, so as to reduce the space of the suction chamber 311 on the side with large garbage amount, and gather the garbage in the suction chamber 311 on the side with large garbage amount through the movement of the baffle 33, and reduce the ineffective airflow at the top of the suction chamber 311 on the side with large garbage amount, increase the suction force of the suction chamber 311 on the side with large garbage amount to pick up garbage, and quickly pick up garbage; when all the garbage is in When the garbage is on one side, the opening and closing device 35 of the garbage-free side closes the connecting component 34 of the garbage-free side to stop the negative pressure suction operation of the suction chamber 311 of the garbage-free side. At the same time, the adjusting driving device 32 drives the barrier member 33 to move slowly toward the garbage side, so as to gather the garbage on the garbage side through the movement of the barrier member 33, reduce the ineffective airflow at the top of the suction chamber 311 of the garbage side, increase the suction force of the suction chamber 311 of the garbage side to pick up the garbage, and quickly pick up the garbage; thereby improving the efficiency of cleaning the road garbage, avoiding the generation of useless work, reducing the driving power of the suction device, avoiding power waste, and saving energy and protecting the environment;

[0050] S3, after the suction chamber 311 finishes sucking up the garbage, the opening and closing device 35 closes the corresponding connecting component 34 to stop the negative pressure suction operation of the two suction chambers 311, the transverse driving device 4 drives the sliding frame 2 to reset, the swing driving device 364 drives the visual device 363 to reset, and the lifting driving device 61 drives the lifting frame 1 to rise to drive the suction nozzle mechanism 3 to rise and then be stored at the bottom of the washing and sweeping vehicle, and the washing and sweeping vehicle operation is completed.

[0051] In order to improve the stability of the suction nozzle mechanism 3 during operation, the lateral movement driving device 4 described in step S1 drives the sliding frame 2 to lateral movement according to the detection feedback of the visual device 363 until the suction nozzle shell 31 corresponds to the back of the garbage and stops, which specifically includes: the lateral movement driving device 4 drives the sliding frame 2 to lateral movement according to the detection feedback of the visual device 363 until the suction nozzle shell 31 corresponds to the back of the garbage and stops, or until the sensing device 314 senses the curb and stops, and the swing driving device 364 drives the swing rod 362 to drive the visual device 363 to swing inward. Therefore, by setting the sensing device 314, the suction nozzle shell 31 is prevented from colliding with the curb and being damaged during the lateral movement, and the visual device 363 is prevented from colliding with the curb and being damaged, thereby improving the stability of the suction nozzle mechanism 3 during operation and extending its service life.

[0054] With the above structure, when the regulating drive device 32 drives the barrier member 33 to slowly move toward the side with a large amount of garbage or the side with garbage, the left sweeping plate 331 and the right sweeping plate 332 can move laterally under the guidance of the first chute 317 and the second chute 318 respectively. When the amount of garbage on the left side is large, the left sweeping plate 331 moves to the left and slides down until the left sweeping part 3312 contacts the ground to sweep the garbage, and the right sweeping plate 332 maintains its original height. The barrier member 33 moves to the left to increase the suction force of the left suction chamber 311. Similarly, when the amount of garbage on the right side is large, the right sweeping plate 332 moves to the right and slides down until the right sweeping part 3322 contacts the ground to sweep the garbage. The plate 331 maintains the original height, and the barrier member 33 moves to the right to increase the suction force of the right suction chamber 311, and then the scraping processing of the left scraping part 3312 and the right scraping part 3322 is improved to improve the collection effect of the garbage on the side with a large amount of garbage or the side with garbage, thereby avoiding residual garbage on the ground and improving the ground cleaning effect of the washing and sweeping vehicle; at the same time, the left sweeping plate 331 and the right sweeping plate 332 can limit the left and right lateral movement of the barrier member 33 in the front and rear directions and the up and down directions under the guidance of the first slide groove 317 and the second slide groove 318 on both sides, thereby avoiding the lateral deviation of the barrier member 33 during the lateral movement and improving the stability of the lateral movement of the barrier member 33.

[0055] The step S2 specifically includes: during the negative pressure suction operation of the two suction chambers 311, the garbage amounts in the two suction chambers 311 detected by the left detection device 312 and the right detection device 313 are compared; if the comparison result shows that the garbage amount on one side is large, the adjustment driving device 32 drives the barrier member 33 to slowly move toward the side with large garbage amount, and the left sweeping plate 331 and the right sweeping plate 332 are respectively moved laterally under the guidance of the first chute 317 and the second chute 318 to reduce the space of the suction chamber 311 on the side with large garbage amount, and the garbage in the suction chamber 311 on the side with large garbage amount is gathered by the movement of the barrier member 33, and the suction chamber 311 on the side with large garbage amount is reduced. 1, the ineffective airflow at the top increases the suction force of the suction chamber 311 on the side with a large amount of garbage to quickly pick up the garbage. When the amount of garbage on the left side is large, the left sweeping plate 331 moves left and slides down to the left sweeping part 3312 to contact the ground to sweep the garbage, the right sweeping plate 332 maintains the original height, and the barrier member 33 moves left to improve the suction force of the left suction chamber 311. Similarly, when the amount of garbage on the right side is large, the right sweeping plate 332 moves right and slides down to the right sweeping part 3322 to contact the ground to sweep the garbage, and the left sweeping plate 331 maintains the original height, thereby improving the collection effect of the garbage on the side with a large amount of garbage through the sweeping treatment of the left sweeping part 3312 and the right sweeping part 3322, thereby avoiding the ground The residual garbage on the surface of the floor can be removed to improve the floor cleaning effect of the floor cleaning vehicle; if the comparison result shows that the garbage is all on one side, the opening and closing device 35 on the garbage-free side closes the connecting component 34 on the garbage-free side to stop the negative pressure suction operation of the suction chamber 311 on the garbage-free side, and at the same time, the adjusting driving device 32 drives the baffle 33 to move slowly toward the garbage side, so as to gather the garbage on the garbage side through the movement of the baffle 33, reduce the ineffective airflow at the top of the suction chamber 311 on the garbage side, increase the suction force of the suction chamber 311 on the garbage side to quickly pick up the garbage; thereby improving the efficiency of cleaning road garbage, avoiding the generation of useless work, and reducing the suction device Driving power, avoiding power waste, energy saving and environmental protection, wherein, when all the garbage is on the left side, the left sweeping plate 331 moves left and slides down to the left scraping part 3312 to contact the ground to scrape the garbage, the right sweeping plate 332 maintains the original height, and the barrier member 33 moves left to increase the suction force of the left suction chamber 311. Similarly, when all the garbage is on the right side, the right sweeping plate 332 moves right and slides down to the right scraping part 3322 to contact the ground to scrape the garbage, the left sweeping plate 331 maintains the original height, and then the scraping treatment of the left scraping part 3312 and the right scraping part 3322 is used to improve the collection effect of the garbage on the garbage side, avoid residual garbage on the ground, and improve the ground cleaning effect of the washing and sweeping vehicle.
