Description

Technical Field

[0001] The present invention relates to the technical field of garbage cleaning vehicles, and particularly to an urban road garbage cleaning vehicle. Background Art

[0002] An urban road garbage cleaning vehicle is applied to the city center to clean the solid waste piled up on the street surface, such as piles of garbage, and is a tool for collecting and loading. During the free movement of the cleaning vehicle, the brushes installed on the vehicle body are driven to work, so as to achieve the effect of removing the solid waste from the street surface.

[0003] When the existing urban road garbage cleaning vehicles are in use, they generally clean and remove the solid waste piled up on the street surface through the kinetic energy during the driving of the vehicle body and the brush structure installed on the front side of the vehicle body. However, in order to reduce the sputtering and dust raising of the waste caused by the centrifugal force of the high-speed rotation of the brush during cleaning, the maximum rotation speed of the brush component is limited, which also leads to low cleaning degree when the cleaning vehicle cleans the adhesive solid waste on the street surface. Due to the adhesiveness or the degree of solidification of the waste on the road surface, it is very easy to have residual waste after cleaning, which takes a long time and has poor cleaning effect during continuous cleaning.

[0004] In view of the above problems, there is an urgent need to innovate and design on the basis of the original urban road garbage cleaning vehicle. Summary of the Invention

[0005] The purpose of the present invention is to provide an urban road garbage cleaning vehicle to solve the problems in the above background art that the existing urban road garbage cleaning vehicles have great difficulty in cleaning the sticky and solidified piled waste when cleaning the solid waste on the street surface, and there are easy to have cleaning residues after cleaning.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An urban road garbage cleaning vehicle, comprising:

[0007] A moving vehicle body, with a front extension frame installed at the bottom of its front side. A cleaning support is arranged on the front extension frame, and the cleaning support realizes the collection of the solid waste piled on the road surface through the cleaning brush installed thereon;

[0008] It further includes: a cleaning brush, which is installed above the cleaning brush in a lifting manner. A tensioning and slackening driving mechanism of the cleaning brush is arranged outside the rotating shaft above the cleaning brush, and the tensioning and slackening states of the cleaning brush are changed by hydraulic filling. The cleaning brush is arranged in a segmented manner, and a tensioning and slackening adjusting part is provided at the segmented part.

[0009] Preferably, a front bucket is also installed on the bottom of the front side of the mobile vehicle body in a lifting manner through a hydraulic device, wherein the front bucket is communicated with the conveying cavity in the middle of the mobile vehicle body, and the conveying cavity is communicated with the collection cavity at the tail of the mobile vehicle body.

[0010] Preferably, the conveying cavity realizes the conveying of solid waste through a screw auger assembly driven by a motor, and conveys the solid waste from the front bucket to the collection cavity to complete the collection of solid waste.

[0011] Preferably, the front extension frame is installed in a lifting manner. A first lifting assembly is provided at the connection between the tail end of the mobile vehicle body and the front extension frame, and an elastic connecting member is also provided between the head end of the front extension frame and the mobile vehicle body.

[0012] Preferably, the cleaning bracket is driven to lift by a second lifting assembly fixed on the head end of the front extension frame. The end of the cleaning bracket is rotatably connected to the middle rotating shaft of the cleaning brush, and the cleaning brush is driven by a motor assembly on the cleaning bracket.

[0013] Preferably, the tensioning and slackening driving mechanism includes a lifting cylinder and a connecting pipe fitting movably installed outside the middle rotating shaft of the cleaning brush. Sealing telescopic rod members are fixedly arranged at equal intervals on the outer wall of the lifting cylinder. A fixing ring is connected between the bottom outer walls of the sealing telescopic rod members. The connecting pipe fitting and the sealing telescopic rod members are internally communicated, and a cleaning brush is connected to the connecting pipe fitting in a through manner.

[0014] Preferably, a connecting ring is also rotatably installed on the upper section of the outer wall of the lifting cylinder. One end of a hydraulic component is hinged to the connecting ring, and the other end of the hydraulic component is hinged to the outside of the cleaning bracket.

[0015] Preferably, a through hole is provided in the middle of the cleaning bracket, and the through hole and the hydraulic component and the lifting cylinder are located in the same projection plane.

[0016] Preferably, the connecting pipe fitting and the sealing telescopic rod members are in one-to-one correspondence. The lower end of the sealing telescopic rod member is made of rubber in a spherical shape, and a shaped groove is provided on the outer wall of the cleaning brush directly below the lower end of the sealing telescopic rod member.

[0017] Preferably, the cleaning brush is arranged in a hollow pipe shape. The adjusting member includes an external thread armor sleeved at the segmented interface of the cleaning brush.

[0019] Through the lifting adjustment of the cleaning brush, when the cleaning brush is in the cleaning work of the sweeping brush, it is placed above the sweeping brush in a soft state, and the sweeping brush is used to clean the solid waste, and it will not cause the collision deformation damage of the cleaning brush itself due to contact collision in the non-use state;

[0020] Furthermore, when there is a large accumulation of solid waste, the cleaning brush is placed in the middle position of the sweeping brush. Under the synchronous action of the sweeping brush and the cleaning brush, the cleaning brush and the sweeping brush are stacked to form a state with moderate hardness, which can drive the excessively accumulated solid waste, and will not cause the sweeping brush to be insufficient in hardness due to too much waste, resulting in a large area of extrusion deformation of the sweeping brush and affecting the cleaning effect of road garbage;

[0021] Furthermore, when stubborn and easily remaining solid waste accumulates, by placing the cleaning brush completely under the sweeping brush and using the extrusion and hydraulic state, the cleaning brush is tightened into a rigid state. When rotating, the stubborn residues on the street road surface are cleaned. At the same time, the cleaning brush that is hidden and in a soft state under normal conditions will not cause the collision of the street road surface, resulting in cross-sectional road surface scratches and knocking damage.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0034] Embodiment 1: Please refer to Figures 1 - 10 , the present invention provides a technical solution: a garbage cleaning vehicle for urban roads, including: a mobile vehicle body 1, a front extension frame 2 is installed at the bottom of the front side thereof, a cleaning bracket 3 is arranged on the front extension frame 2, and the cleaning bracket 3 realizes the collection of solid waste accumulated on the road surface through the cleaning brush 4 installed thereon; a front bucket 101 is also installed on the bottom of the front side of the mobile vehicle body 1 in a lifting manner through hydraulic equipment, wherein the front bucket 101 is communicated with the conveying cavity 102 in the middle of the mobile vehicle body 1, and the conveying cavity 102 is communicated with the collection cavity 103 at the tail of the mobile vehicle body 1; the conveying cavity 102 realizes the conveying of solid waste through a spiral auger assembly driven by a motor, and conveys the solid waste from the front bucket 101 to the collection cavity 103 to complete the collection of solid waste; the front extension frame 2 is installed in a lifting manner, wherein a first lifting component 201 is provided at the connection between the mobile vehicle body 1 and the tail end of the front extension frame 2, and an elastic connection member 202 is also provided between the head end of the front extension frame 2 and the mobile vehicle body 1; the cleaning bracket 3 is driven to lift by a second lifting component 301 fixed on the head end of the front extension frame 2, wherein the end of the cleaning bracket 3 is rotatably connected to the middle rotating shaft of the cleaning brush 4, and the cleaning brush 4 is driven by the motor component 401 on the cleaning bracket 3;

[0035] In the above technical solution, during use, for the accumulation of ordinary solid waste, when the mobile vehicle body 1 travels to the position where the waste is accumulated, the front bucket 101 is driven to descend by the hydraulic device, and the front extension frame 2 is controlled to descend by the first lifting assembly 201. The second lifting assembly 301 on the front extension frame 2 controls the cleaning bracket 3, so that the cleaning brush 4 can directly contact the accumulated solid waste on the road surface and streets. When the cleaning brush 4 is driven to rotate by the motor assembly 401 and the front bucket 101 on the mobile vehicle body 1 moves forward, the accumulated solid waste on the street is guided into the front bucket 101 and the conveying cavity 102, and the solid waste is collected into the collection cavity 103 by the spiral auger assembly to complete the loading. In the above solution, the first lifting assembly 201 and the second lifting assembly 301 can be controlled electromagnetically or hydraulically, which is convenient for cleaning the accumulated solid waste on the street and can avoid the collision of the front extension frame 2 and the cleaning bracket 3 caused by the mobile vehicle body 1 during the non-waste cleaning state when the mobile vehicle body 1 is driving.

[0036] Further, adopting the technical solution as Figures 4 - 6 shown, the cleaning brush 5 is installed above the cleaning brush 4 in a lifting manner. A tensioning and slackening driving mechanism of the cleaning brush 5 is arranged outside the upper shaft of the cleaning brush 4, and the tensioning and slackening state of the cleaning brush 5 is changed by hydraulic filling. The cleaning brush 5 is arranged in a segmented manner, and a tensioning and slackening adjusting member is provided at the segmentation position; the tensioning and slackening driving mechanism includes a lifting cylinder 502 movably installed outside the middle shaft of the cleaning brush 4 and a connecting pipe fitting 506. Sealing telescopic members 504 are fixedly arranged at equal intervals on the outer wall of the lifting cylinder 502. A fixing ring 505 is connected between the bottom outer walls of the sealing telescopic members 504. The connecting pipe fitting 506 is internally communicated with the sealing telescopic members 504, and the cleaning brush 5 is connected to the connecting pipe fitting 506 in a penetrating manner; a connecting ring 503 is also rotatably installed on the upper section of the outer wall of the lifting cylinder 502. One end of a hydraulic component 501 is hinged to the connecting ring 503, and the other end of the hydraulic component 501 is hinged to the outside of the cleaning bracket 3; a through hole is arranged in the middle of the cleaning bracket 3, and the through hole, the hydraulic component 501 and the lifting cylinder 502 are located in the same projection plane; the connecting pipe fitting 506 and the sealing telescopic members 504 correspond one by one. The lower end of the sealing telescopic member 504 is made of rubber in a spherical shape, and a shaped groove is arranged on the outer wall of the cleaning brush 4 directly below the lower end of the sealing telescopic member 504;

[0037] In the above technical solution, when cleaning a small amount of accumulated solid waste on the street, it is directly cleaned by the cleaning brush 4. At this time, the cleaning brush 5 is located above the cleaning brush 4. Since the tension-relaxation drive mechanism is not enabled, the cleaning brush 5 is set in a soft state on the cleaning brush 4 and remains relatively stationary when the cleaning brush 4 rotates, without affecting the use of the cleaning brush 4. At the same time, it will not cause deformation and damage to the cleaning brush 5 due to collisions and squeezes caused by external factors. The soft cleaning brush 5 has a good force-relieving protection effect. At the same time, when cleaning a large amount of accumulated solid waste, the cleaning brush 5 is moved downward to the middle position of the cleaning brush 4. The hydraulic component 501 extends outward and drives the sealed telescopic rod member 504 fixed on the lifting cylinder 502 to move downward through the connecting ring 503, so that the spherical structure at the lower end of the sealed telescopic rod member 504 is introduced into the groove structure of the cleaning brush 4, and the oil liquid in it is compressed into the cleaning brush 5. Since the sealed telescopic rod member 504 is not fully compressed, the cleaning brush 5 is in a semi-tight state at this time and can rotate synchronously with the cleaning brush 4. The cleaning brush 4 and the cleaning brush 5 are superimposed to improve their own anti-deformation strength, so that when cleaning a large amount of accumulated solid waste, the single cleaning brush 4 will not be quickly deformed due to the large weight, affecting the cleaning effect of the waste. In the above two processes, the cleaning brush 5 is set in a hidden manner and will not cause scratches and collision damage to the street surface due to use. When independently cleaning the waste with strong residue on the road, the cleaning brush 5 is moved below the cleaning brush 4, and the hydraulic component 501 is used to drive the sealed telescopic rod member 504 to move downward to the maximum extent. At this time, under the hydraulic action, the cleaning brush 5 moves below the cleaning brush 4 and is tightened into a rigid state and rotates synchronously when the cleaning brush 4 rotates. The cleaning brush 5 is used to squeeze and rub the solid residual waste to complete the cleaning of the solid waste. In the above technical solution, the cleaning brush 5 and the cleaning brush 4 can be synchronously provided with a flushing and drainage structure at the use position to clean the dirt of the solid waste after cleaning.

[0038] For another example Figures 7 - 9 As shown, the cleaning brush 5 is arranged as a hollow pipe. The adjusting member includes an external thread armor 6 sleeved at the segmented interface of the cleaning brush 5. An elastic inner lining 7 is provided inside the external thread armor 6. An internal hose 8 is provided inside the cleaning brush 5. The elastic inner lining 7 is connected and communicated with the internal hose 8, the connecting pipe fitting 506 and the sealed telescopic rod member 504 and is filled with oil liquid inside. The outer side materials of the cleaning brush 5 and the external thread armor 6 are hard metals. The segmented cleaning brush 5 has good flexibility in the natural state, can be hidden and protected without self-destruction caused by collisions, and will not directly contact the street ground, causing scratches and collision damage to the street ground. When injecting oil liquid into the inside of the cleaning brush 5, the elastic inner lining 7 expands from the original contracted state and fills the gaps of the segmented cleaning brush 5 to achieve the use effect of the overall tightening, rigidity and hardening of the cleaning brush 5. The external thread armor 6 is arranged in a spiral structure and can be deformed and bent and has a good wear-resistant use effect.

[0039] Embodiment 2: On the basis of Embodiment 1, as shown in the present invention Figure 10 , an elastic member is further provided between the sealed telescopic rod member 504 and the fixed ring 505. The function of this elastic member is that when the cleaning brush 5 resumes moving above the cleaning brush 4, the elastic force of the elastic member can quickly cause the sealed telescopic rod member 504 to recover from the compressed state to the expanded state, sucking out the oil in the cleaning brush 5, so that the cleaning brush 5 recovers from the taut state to the soft state. In Embodiment 1, the oil in the cleaning brush 5 is discharged by the elastic force of the elastic inner lining 7; the function of the above elastic member speeds up the deformation reset of the cleaning brush 5.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
