Description

Technical Field

[0001] The invention belongs to the technical field of road cleaning and relates to a garbage crushing device for a sanitation vehicle. Background Art

[0002] With the introduction of policies such as the Blue Sky Defense Campaign and Beautiful Countryside, environmental protection requirements in cities, towns and villages are constantly increasing. More and more roads need to be cleaned and maintained, and the workload is increasing. However, manual cleaning operations are costly and inefficient. Therefore, mechanized cleaning operations represented by road sweepers and washing and sweeping vehicles are rapidly promoted. At present, the suction nozzles of road sweepers in the industry are less effective in handling large volumes of garbage on the road. As long as it is in the autumn and winter seasons, when there are many fallen leaves and branches on the ground, they are very easy to get stuck in the suction pipe of the suction nozzle, causing the system air volume to gradually decrease, and the suction force of the suction nozzle to gradually decrease until it is completely blocked and there is no suction, causing the sweeper to lose its operating ability and requiring manual parking to clear and clean, affecting the operating effect and efficiency. At the same time, the existing blade group is driven by a longer drive shaft to rotate at high speed, so the resistance torque is large, the energy consumption is high, and the radial runout is large when rotating at high speed, which can easily cause structural damage and affect the service life.

[0003] In order to overcome the shortcomings of the prior art, people have proposed various solutions through continuous exploration. For example, a Chinese patent discloses a crushing device and a road sweeper suction nozzle [application number: 201711059932.3], wherein the crushing device includes a transmission shaft (10) and a crushing assembly arranged on the transmission shaft (10) and capable of rotating with the transmission shaft (10), wherein the crushing assembly includes a cutter seat, wherein the cutter seat is provided with a first disturbance plate (30) and a blade shaft (50), wherein the blade shaft (50) is provided with a blade (51); the cutter seat is sleeved on the transmission shaft (10) and capable of rotating with the transmission shaft (10). The crushing capacity of the crushing device can be effectively improved by the disturbance effect of the first disturbance plate. However, the shaft of this solution is relatively long and the structure is bulky. During the rotation process, the resistance torque is relatively large, resulting in high energy consumption; and the coaxiality of the axial installation is relatively poor, and the vibration is frequent, thereby damaging the bearing seat and affecting the service life.

The resistance torque is small during driving, the energy consumption is low, the radial runout is reduced during high-speed rotation, it is not easy to cause structural damage, and the service life is long. At the same time, the suspended special-shaped crushing blade assembly 6 can crush long strips of garbage such as tree branches entering the suction pipe 4 in any posture, and its crushing ability is stronger than that of traditional blades, the crushing effect is good, and the anti-blocking effect is significantly improved.

[0030] Combination Figure 1 , Figure 2 As shown, the suction pipe 4 is connected to the cover shell 5, and the suspended special-shaped crushing blade assembly 6 includes a crushing blade disc 7 arranged at one end of the inner side of the cover shell 5, and the crushing blade disc 7 is equipped with a plurality of longitudinal blades 8 arranged longitudinally and transverse blades 9 arranged transversely.

[0031] Specifically, the crushing blade disc 7 is designed to replace the longer rotating shaft in the prior art, and the structure is simple. At the same time, the longitudinal blade 8 and the transverse blade 9 are designed to reduce the number of blade groups while ensuring that the blade rotating crushing area basically covers the inside of the cover shell 5, and the transverse blade 9 is partially located on the outside of the entire blade. The linear speed is high and the crushing ability is stronger than that of traditional blades. After the number of blades is reduced, the mass is lighter, the corresponding rotational inertia is smaller, the resistance torque is smaller, and the driving power can be significantly reduced.

[0032] Combination Figure 2 As shown, the crushing blade 7 is connected to one end of the inner side of the cover shell 5, and the crushing blade 7 is suspended away from the inner end of the cover shell 5 in a cantilever form, and the center line of the longitudinal blade 8 and the center line of the transverse blade 9 are perpendicular to each other.

When the transverse blade 9 rotates around the axis of the crushing blade disc 7, the transverse blade 9 extends away from one end of the crushing blade disc 7 and passes into the suction nozzle body 3 and the suction pipe 4.

[0035] In this embodiment, when the transverse blade 9 rotates around the axis of the crushing disc 7, the transverse blade 9 extends away from one end of the crushing disc 7 and passes into the suction nozzle body 3 and the suction pipe 4, ensuring that the garbage entering the suction pipe 4 is crushed, ensuring the crushing area, and the crushing effect is better.

[0036] Combination Figure 5 , Figure 6 As shown, the sanitation vehicle body 1 is provided with a circumferential rotator 10, the rotating shaft of the circumferential rotator 10 extends into the cover 5 and is connected to the crushing blade 7, and the cover 5 is rotatably provided with a sealed bearing at one end close to the circumferential rotator 10, the rotating shaft of the circumferential rotator 10 passes through the sealed bearing and the rotating shaft of the circumferential rotator 10 rotates in cooperation with the sealed bearing.

[0037] In this embodiment, when it is necessary to rotate the shredding blade disc 7, the circumferential rotator 10 is started, and the shredding blade disc 7 is driven to rotate by the rotating shaft of the circumferential rotator 10, so that the longitudinal blade 8 and the transverse blade 9 can quickly shred the garbage. The sealed bearing limits the rotating shaft of the circumferential rotator 10 to prevent radial runout of the rotating shaft of the circumferential rotator 10 during rotation. Those skilled in the art should understand that the circumferential rotator 10 can be a motor or a rotary cylinder.

[0044] After the garbage is sucked from the suction nozzle body 3, it enters the suction pipe 4 and is started. The circumferential rotator 10 drives the crushing cutter disc 7 to rotate through the rotating shaft of the circumferential rotator 10, so that the longitudinal blade 8 and the transverse blade 9 can quickly crush the garbage. By designing the longitudinal blade 8 and the transverse blade 9, while reducing the number of blade groups, it is ensured that the blade rotation crushing area basically covers the inside of the cover 5, and the transverse blade 9 is partially located outside the entire blade, the linear speed is high, and the crushing ability is stronger than that of the traditional blade.
