Description

Technical Field

[0001] This invention relates to the field of road sweeping equipment technology, and specifically to a sweeper vehicle sweeping device for washing and sweeping operations. Background Technology

[0002] Traditional sweeper trucks typically consist of four sweeping components, each comprising a sweeping disc and a mechanism that moves the disc. Two sweeping components are arranged in a row on either side of the vehicle. The front sweeping disc extends beyond the width of the vehicle, positioned close to the road edge to sweep and gather litter. The rear sweeping disc, located within the width of the vehicle, further gathers litter towards the center of the vehicle.

[0003] For highways and urban elevated roads where traffic moves at high speeds, sweeper trucks need to maintain high speeds for cleaning. Due to the limited sweeping distance of the sweeping discs, the sweeping width of the sweeper truck is relatively small, and the distance between the sweeping discs and the curb is very close. When sweeping at high speeds, the driver needs to concentrate highly to control the vehicle's distance from the curb (i.e., the safe distance between the vehicle and the curb), which can easily lead to driver fatigue. At the same time, when using the sweeping discs for cleaning, in order to ensure the cleaning effect when sweeping at high speeds, the sweeping discs need to rotate at high speeds to thoroughly sweep up the garbage along the curb. The high-speed rotation of the sweeping discs gives the particles of garbage a lot of kinetic energy. Because the rear sweeping discs are close to the center of the vehicle, some particles of garbage cannot stop in time in the center area of ​​the vehicle, resulting in garbage splashing and rolling onto adjacent roads, causing garbage to be missed and affecting the driving safety of surrounding roads. Summary of the Invention

[0004] The purpose of this invention is to provide a sweeping device for sweeping operations, in order to solve the technical problems mentioned in the background art, namely, the limited sweeping range of the sweeping disc and the tendency for garbage to splash. To solve the above problems, this invention adopts the following technical solution: In a first aspect, the present invention provides a sweeping device for a sweeper vehicle performing a sweeping operation, comprising: The frame is used to mount the sweeper on the chassis, and the underside of the chassis forms the vehicle body coverage area; The front cleaning mechanism is symmetrically installed on both sides of the front of the vehicle frame, including: a sweeping disc that can partially extend beyond the coverage area of ​​the vehicle body, and a front nozzle located outside the sweeping disc; the front nozzle is inclined towards the front of the vehicle frame to blow garbage towards the front of the sweeping disc by spraying; the sweeping disc is used to sweep garbage in front of its area towards the vehicle frame area; The rear cleaning mechanism is symmetrically installed on both sides of the rear of the vehicle frame, including: a rear nozzle, located within the vehicle body coverage area, which is tilted towards the front of the vehicle frame and sprays a mist forward to blow the debris between the vehicle body and the sweeping disc toward the vehicle frame area; A suction cup is located at the rear end of the vehicle frame and is used to suck up trash near the vehicle frame area.

[0005] Optionally, the front cleaning mechanism further includes: The front bracket is connected to the vehicle frame; The connecting rod has a first end connected to the front bracket and a second end provided with a mounting base for mounting the sweeping disc and a front mounting bracket movably mounted on the mounting base. The front spray bar is movably mounted on the front mounting bracket, forming a reverse angle with the connecting rod, and is inclined toward one side of the vehicle frame. The front nozzle is mounted on the front spray bar.

[0006] Optionally, the first end of the linkage is movably connected to the front bracket, and the linkage is capable of rotating around the first end to carry the sweeping disc to extend or retract into the vehicle body coverage area.

[0007] Optionally, the front mounting bracket can rotate about the vertical direction relative to the mounting base; the front spray bar can rotate about its own axis to adjust the angle between the straight line of the spray direction of the front nozzle and the ground.

[0008] Optionally, one or more front nozzles are provided, the angle between the spray direction of the front nozzle and the ground is 30° to 60°, and the nozzle maintains a height of 100mm to 400mm above the ground.

[0009] Optionally, the spray contact line of the front nozzles of the front sweeping mechanism located on both sides of the vehicle frame forms a V-shape with the center line of the sweeper's direction of travel.

[0010] Optionally, the rear cleaning mechanism includes: The rear bracket is connected to the rear of the vehicle frame; The rear spray bar is mounted on the rear bracket, and all the rear nozzles are located on the rear spray bar.

[0011] Optionally, the rear spray bar is movably mounted on the rear mounting bracket of the rear support, and the rear spray bar can rotate around its own axis to adjust the angle between the straight line of the spray direction of the rear nozzle and the ground.

[0012] Optionally, the rear mounting bracket is movably mounted on the rear support and forms a hinge point at the connection point between the rear mounting bracket and the rear support. The rear mounting bracket can rotate around the hinge point to adjust the orientation of the rear spray bar.

[0013] Optionally, one or more rear nozzles are provided, the angle between the spray direction of the rear nozzle and the ground is 30° to 60°, and the distance from the ground is maintained at 100mm to 400mm.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention adds a front spray bar and a front nozzle to the outside of the sweeping disc of the front sweeping mechanism. This expands the sweeping range by covering the outside of the sweeping disc. Furthermore, during sweeping, the sweeping disc does not need to be pressed against the curb; instead, the adjustable front spray bar can be pressed against the curb, thereby increasing the distance between the sweeper and the curb and significantly reducing the driver's workload.

[0015] 2. For the rear cleaning mechanism, the present invention directly selects the rear nozzle to blow away the garbage instead of the sweeping disc. Since the spray impact force of the rear nozzle is smaller than that of the sweeping disc, it can better prevent the garbage from being blown away and ensure that the garbage can stay in the area that the suction cup of the frame can cover after being blown away.

[0016] 3. In this invention, both the front and rear spray booms are adjustable. When the sweeper is in operation, the angles between the front and rear spray booms and the horizontal direction, as well as the angles between the front and rear nozzles and the ground, can be adjusted according to the operating speed to ensure that the impact force generated by the spray can push the garbage to gather together, so that the sweeper can maintain the best sweeping effect at different driving times.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention. Example 1

[0019] Combination Figure 1-2This embodiment provides a sweeping device for a sweeper truck, which includes: a frame 5 for mounting on the chassis of the sweeper truck, with the lower side of the chassis forming a vehicle body coverage area; a right front sweeping assembly 1 and a left front sweeping assembly 2 are mounted on the front of the frame 5; Combination Figure 4-5 In the figure, both the right front cleaning assembly 1 and the left front cleaning assembly 2 are in a cleaning state. Specifically, both the right front cleaning assembly 1 and the left front cleaning assembly 2 include a front cleaning mechanism, which includes a sweeping disc 1-7 that can partially extend beyond the vehicle body coverage area, and a front nozzle 1-4 located outside the sweeping disc 1-7. The front nozzle 1-4 is tilted towards the side front of the vehicle frame to blow garbage towards the front of the sweeping disc 1-7 through spraying. The sweeping disc 1-7 is used to sweep garbage in front of its current area towards the vehicle frame area. Specifically, in this embodiment, the front cleaning mechanism has two main components: a sweeping disc 1-7 and a front nozzle 1-4. The front nozzle 1-4 is located on the outside of the sweeping disc 1-7. The front nozzle 1-4: On the one hand, it can blow the garbage located in front of the outer side of the sweeping disc 1-7 to the front of the inner side of the sweeping disc 1-7, thereby expanding the cleaning range of the entire front cleaning mechanism. On the other hand, it also makes it easier for the sweeping disc 1-7 to directly sweep the garbage in front of the inner side to one side of the frame during the rotating cleaning process. On the other hand, the front nozzle 1-4 is mounted on the extended spray bar, which not only increases the sweeping width of the whole vehicle but also increases the vehicle's edge-to-edge distance, that is, the distance between the vehicle body and the curb. At this time, the outermost part of the entire front sweeping mechanism is the front nozzle 1-4 and the spray bar used to mount the front nozzle 1-4, rather than the sweeping disc 1-7. Moreover, the spray bar itself has a certain degree of adjustability, and can be adjusted and reset even if it touches the curb.

[0020] Traditional sweepers clean by having their sweeping discs 1-7 brush against the curb. Since the sweeping discs 1-7 cannot extend too far from the vehicle body to avoid difficulty in sweeping garbage to the suction cup area on the vehicle body, the vehicle body is also close to the curb. To ensure vehicle safety, this places extremely high demands on the driver's skill level. Compared to the sweeping discs 1-7 brushing against the curb, the sweeping device in this embodiment increases the distance between the vehicle body and the curb, and the spray bar brushing against the curb can be adjusted and reset, greatly reducing the driving difficulty for sweeper drivers.

[0021] The spray direction of the front nozzles 1-4 on the right front cleaning assembly 1 is towards the left front, and the spray direction of the front nozzles 1-4 on the left front cleaning assembly 2 is towards the right front. The spray contact line formed by the front nozzles 1-4 on both sides on the ground is arranged in a V-shape relative to the center line of the vehicle frame.

[0022] Based on the horizontal and vertical decomposition of force, the spray from the front nozzles 1-4 propels the garbage forward while simultaneously pushing it towards the center of the vehicle, i.e., the side of the frame. When the garbage reaches the front of the sweeping discs 1-7, the sweeping action of the discs further pushes it towards the center of the vehicle, i.e., the side of the frame. This gathers the garbage from the curb towards the frame, ready for suction from the suction cups.

[0023] Ultimately, the debris swept towards the vehicle frame area by sweeping discs 1-7 can be sucked up by the suction cup at the rear end of the vehicle frame during the sweeper's movement, thus completing the cleaning process.

[0024] Specifically, the front cleaning mechanism in this embodiment further includes: a front bracket 1-1 and a connecting rod 1-2 connected to the vehicle frame; The first end of the connecting rod 1-2 is connected to the front bracket 1-1; the second end is provided with a mounting seat 1-3 for mounting the sweeping disc 1-7 and a front mounting bracket 1-6 movably mounted on the mounting seat 1-3; The first end of the connecting rod 1-2 is movably connected to the bracket, and the connecting rod 1-2 can rotate around the first end to extend or retract the sweeping disc 1-7 into the vehicle's coverage area. The sweeping disc 1-7 remains extended during cleaning and retracts into the vehicle when not cleaning.

[0025] In addition, the front spray bar 1-5 for mounting the front nozzle 1-4 is movably mounted on the front mounting bracket 1-6, forming a reverse angle with the connecting rod 1-2, and is inclined toward one side of the vehicle frame; The front spray boom 1-5 can first rotate around its own axis to adjust the angle between the straight line of the spray direction of the front nozzle 1-4 and the ground, thereby adjusting the spray angle. It can also rotate with the front mounting bracket 1-6 relative to the mounting base 1-3 in a vertical direction to adjust the angle of the front spray boom 1-5. This angle adjustment of the spray boom with the mounting base 1-3, in conjunction with the rotation of the front spray boom 1-5, allows for coordinated adjustment of the front nozzle 1-4 in two degrees of freedom.

[0026] Furthermore, depending on the actual cleaning width requirements, one or more front nozzles 1-4 are provided. The spray direction of the front nozzles 1-4 can be adjusted by the front spray bar 1-5. The angle between the straight line of the spray direction and the ground is 30°~60°, and the distance from the ground is maintained at 100mm~400mm. Example 2

[0027] Same as Example 1, except that: [The following text appears to be incomplete and requires further context: "combining..."] Figure 3 In this embodiment, the sweeper cleaning device further includes a right rear sweeping assembly 3 and a left rear sweeping assembly 4 symmetrically installed on both sides of the rear of the vehicle frame; combined with Figure 4-5The right rear cleaning component 3 and the left rear cleaning component 4 shown in the figure are both in the cleaning state; Both the right rear cleaning assembly 3 and the left rear cleaning assembly 4 include a rear cleaning mechanism; The rear cleaning mechanism includes: The rear nozzle 3-2 is located within the vehicle body coverage area and is tilted towards the front of the vehicle frame to spray a mist forward, blowing the garbage between the vehicle body and the sweeping discs 1-7 toward the vehicle frame area; so that it can be sucked up by the suction cup at the rear end of the vehicle frame later. The rear nozzles 3-2 in the right rear cleaning assembly 3 and the left rear cleaning assembly 4 spray towards the left front and right front respectively, forming a V-shaped layout relative to the center line of the vehicle frame.

[0028] Specifically, in this embodiment, the rear cleaning mechanism uses only the rear nozzle 3-2 to blow the garbage in the area toward the vehicle frame. Compared with the sweeping disc 1-7 in the traditional structure, the spray impact force of the rear nozzle 3-2 is smaller, and the kinetic energy given to the garbage is also smaller. After the garbage is blown, it will not be blown away or thrown out, thus it will stay stably in the vehicle frame area for the suction cup to pick up. This better avoids missed sweeping caused by garbage splashing and also ensures the driving safety of the surrounding roads.

[0029] Meanwhile, the rear nozzle 3-2, which sprays forward in this embodiment, can also buffer the garbage swept backward by the high-speed rotating sweeping disc 1-7 of the front sweeping mechanism. This reduces the distance the garbage flies out of the vehicle frame area, thus avoiding affecting the driving safety of the surrounding roads.

[0030] Specifically, the rear cleaning mechanism includes: a rear support 3-1 connected to the rear of the vehicle frame, and a rear spray bar 3-4 mounted on the rear support 3-1, wherein the rear nozzles 3-2 are all located on the rear spray bar 3-4.

[0031] Furthermore, the rear spray bar 3-4 is movably mounted on the rear mounting bracket 3-3 on the rear support 3-1. The rear spray bar 3-4 can rotate around its own axis to adjust the angle between the straight line of the spray direction of the rear nozzle 3-2 and the ground.

[0032] Meanwhile, the rear mounting bracket 3-3 is movably mounted on the rear support 3-1, and a hinge point is formed at the connection point between the rear mounting bracket 3-1 and the rear support 3-1. The rear mounting bracket 3-3 can rotate around the hinge point to adjust the orientation of the rear spray bar 3-4.

[0033] Both the rear spray bar 3-4 and the rear mounting bracket 3-3 can be rotated, so that when the sweeper is working, the angle between the rear spray bar 3-4 and the horizontal direction and the angle between the rear nozzle 3-2 and the ground can be adjusted according to the working speed, so as to ensure that the impact force generated by the spray can push the garbage to gather, and the sweeper can maintain the best sweeping effect at different driving times.

[0034] Depending on the actual cleaning width requirements, one or more rear nozzles 3-2 are provided. By adjusting the rear spray frame, the angle between the spray direction of the rear nozzle 3-2 and the ground can be maintained within the range of 30° to 60° to meet the cleaning needs under different conditions. At the same time, the nozzle maintains a ground clearance of 100mm to 400mm.

[0035] Combination Figures 6-7 When the sweeper finishes its work, the sweeping device is adjusted to the non-working device, the sweeping disc 1-7 and the spray bar are retracted to the width range of the vehicle, the sweeping disc 1-7 is raised and lifted off the ground, the front nozzle 1-4 and the rear nozzle 3-2 both stop spraying, the front spray bar 1-5 and the rear spray bar 3-4 are reset, and the sweeping is completed.

[0036] 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.
