Description

TECHNICAL FIELD

[0001] The present application relates to ground garbage cleaning equipment, in particular to a rolling bucket, a vehicle-mounted ground blowing device and a ground blowing vehicle, which are used for being installed on a moving vehicle as a ground garbage cleaning vehicle. BACKGROUND

[0002] The existing garbage cleaning vehicle uses a vacuum adsorption method to clean the garbage on the ground. However, in the actual use process, the vacuum adsorption method often has problems such as low cleaning efficiency and poor cleaning effect. Although the existing technology also uses air blowing or a portable air blowing machine held by a cleaning personnel to blow the ground to improve the cleaning efficiency, the garbage can only be blown to one side and cannot be picked up, and the garbage still needs to be cleaned by manual or cleaning vehicle. SUMMARY

The waste inlet of the waste collection pipe is close to and aligned with the waste outlet of the hopper, and the waste outlet of the waste collection pipe is located at the rear of the vehicle frame. The waste collection pipe is mounted on the vehicle frame, and the waste inlet of the waste collection pipe matches the waste outlet of the hopper to receive waste (the waste collection pipe is not fixed to the hopper, so the waste collection pipe remains stationary when the hopper rotates). A collection bag is also provided at the waste outlet of the waste collection pipe. After the waste is discharged from the waste outlet of the hopper, it enters the waste collection pipe and finally falls into the collection bag.

[0020] Preferably, the wheel rim on one side of the first port also has a wheel rim flange, the inner ring of the rolling bearing has an inner flange, the inner ring of the rolling bearing is fixed to the wheel rim flange through the inner flange, the outer ring of the rolling bearing has an outer flange, and the left and right palm plates are respectively provided with flange mounting holes, and the outer ring of the rolling bearing is fixed to the left and right palm plates of the arm through the outer flange.

[0022] Preferably, an in-pipe sweeper is also provided. The in-pipe sweeper is installed and fixed on the garbage collection pipe. The nozzle of the in-pipe sweeper is connected to the inside of the garbage collection pipe and sweeps the garbage in the pipe, causing it to move towards the rear of the vehicle frame and finally fall into the collection bag.

[0023] Preferably, a lifting device for the garbage collection pipe is also provided. The lifting device includes a frame, and the upper side of the frame has a long support. The long support is hinged to the support of the vehicle frame via a hinge.

The electric push rod is located on the lower side of the support frame. The electric push rod drives the support frame to rotate upward around the axis, lifting the vehicle frame and lifting the bucket off the ground.

[0025] A ground sweeping vehicle includes a mobile vehicle, said vehicle including a frame (such as the rear frame of a truck);

[0026] It also includes the roller bucket (including shaftless rollers) and is provided with a rolling bearing, wherein the shaft hole of the rolling bearing and the wheel cavity of the wheel rim form an integral wheel cavity;

[0027] It is also provided with a clasp arm, which has a body and a left clasp arm and a right clasp arm extending forward from the left and right sides of the body, respectively.

[0028] Located on one side of the first port, the inner ring of the rolling bearing is mounted and fixed on the wheel rim, and the outer ring of the rolling bearing is mounted and fixed on the left palm plate and the right palm plate, thereby making the arm, like the two arms of a human body, tightly fix the roller end from both sides of the wheel rim and make the opening of the conical bucket located in front of the chest.

[0029] A first blower is also provided. The first blower is mounted and fixed by the vehicle frame and its air outlet faces the opening of the conical bucket.

The waste inlet of the waste collection pipe is close to and aligned with the waste outlet of the hopper, and the waste outlet of the waste collection pipe is located at the rear of the vehicle frame. The waste collection pipe is mounted on the vehicle frame, and the waste inlet of the waste collection pipe matches the waste outlet of the hopper to receive waste (the waste collection pipe is not fixed to the hopper, so the waste collection pipe remains stationary when the hopper rotates). A collection bag is also provided at the waste outlet of the waste collection pipe. After the waste is discharged from the waste outlet of the hopper, it enters the waste collection pipe and finally falls into the collection bag.

[0031] A parallel four-bar linkage mechanism is also provided, which consists of an upper link, a first vertical link, a lower link, and a second vertical link. The links of the parallel four-bar linkage mechanism are connected in sequence by hinges.

[0032] The second vertical rod is installed and fixed on the frame in a vertical state, and the running plane of the parallel four-bar linkage is perpendicular to the direction of vehicle movement. During the operation of the parallel four-bar linkage, the second vertical rod is fixed, and the upper and lower linkages rotate around their respective hinge pins connected to the second vertical rod and are always parallel to each other. Therefore, the first vertical rod always remains vertical.

[0034] A support mechanism is also provided to drive the parallel four-bar linkage mechanism to rise and fall. The support mechanism is installed on the lower side of the parallel four-bar linkage mechanism and consists of a support frame and a linear drive device, which is an electric push rod or a cylinder piston. The proximal end of the support frame is hinged to the body of the moving vehicle via a hinge. A support wheel is provided on the upper side of the far end of the support frame. A lifting plate is provided on the upper linkage. The support wheel is located on the lower side of the lifting plate and there is a gap between the support wheel and the lifting plate. The gap allows the roller to rise and fall and bounce when traveling on uneven ground, and always remain in a grounded state. The electric push rod is located on the lower side of the support frame. The electric push rod drives the support frame to rotate upward around the axis and lifts the parallel four-bar linkage mechanism and the bucket off the ground through the lifting plate.

[0035] The beneficial effects of this invention are as follows: This invention proposes a rolling bucket, a vehicle-mounted ground sweeping device, and a ground sweeping vehicle. Because it has a rolling bucket that rolls close to the ground, garbage on the ground can be directly blown into garbage collection bins or bags. Furthermore, since the rolling bucket has no spokes or hubs, there is no obstruction when garbage enters the garbage collection bins or bags. Compared with existing technologies, it not only sweeps faster but also sweeps more thoroughly. The equipment has high energy efficiency, further improving the efficiency of ground cleaning operations, reducing labor intensity, and the system is stable and reliable, effectively solving the problems of existing technologies.

[0060] Figures 1-13 This is a schematic diagram of the structure of the first embodiment of the present invention. This example provides a shaftless rolling bucket.

[0061] As shown in the figure, the shaftless bucket in this example includes a flap, which is composed of a thin sheet 5.0 with elastic deformation properties. Figure 1 and Figure 2 The figure shows that when the sheet 5.0 is unfolded, it has a planar fan-shaped ring structure. When rolled up, it forms a complete conical hopper 5, which is used to collect ground waste. The figure also shows that radial notches 5A, 5B, 5C, 5D, 5E, and 5F are respectively provided on the inner circle of the sheet 5.0.

[0062] Figures 3-13 As shown, in this example, the shaftless hopper also includes a shaftless roller 1. The shaftless roller 1 includes a rim 1.3 and a tire 1A on the outside of the rim. The inside of the rim 1.3 forms a wheel cavity 1.3A. The two ends of the rim 1.3 form a first port 1.31 and a second port 1.32. The flaps are fixed around the first port 1.31 of the rim and form a conical hopper 5 that flares outward. The conical hopper 5 and the rim 1.3 are on the same central axis and the diameter of its circular opening 5_1 is larger than the outer diameter of the roller 1. The opening (i.e., the large opening) of the conical hopper 5 is the garbage inlet.

[0063] When the roller 1 rolls along the ground, the conical bucket 5 rolls synchronously and the part of the bucket opening 5_1 that touches the ground is deformed by pressure and extends outward to fit the ground to receive the garbage. The garbage on the ground enters from the bucket opening 5_1, passes through the wheel cavity 1.3A and is discharged from the small opening of the conical bucket 5.

[0064] In this example, a conical support tube 7A3 for fixing the blade is also provided in the wheel cavity 1.3A. The conical support tube 7A3 is on the same central axis as the wheel rim 1.3, and the large opening of the conical support tube 7A3 faces the outside of the first port 1.31 while the small opening faces the outside of the second port 1.32 (the small opening of the conical support tube 7A3 constitutes the garbage discharge outlet).

[0065] In this example, there is a slot 7C12 between the inner wall of the wheel rim 1.3 and the conical support tube 7A3 for inserting the rolled-up flaps. Multiple ribs 1.37 are radially arranged in the slot 7C12. The conical support tube 7A3 is installed and fixed (welded) by the ribs 1.37, and the flaps are fitted and fixed to the outer wall of the conical support tube 7A3. In this example, the outer edge 1.371 of the rib 1.37 is welded and fixed to the inner wall surface 1.3.1 of the wheel rim 1.3, while the outer conical wall surface of the conical support tube 7A3 is welded and fixed to the inner edge 1.372 of the rib 1.37. Through the welding and fixing of multiple ribs 1.37, the wheel rim 1.3 and the conical support tube 7A3 are welded and fixed together as a single unit.

[0066] Figure 8 , 9 Figures 10 and 13 are enlarged structural diagrams of the insert 7C. Among them, Figure 8 This is an enlarged schematic diagram of the 3D structure of the insert 7C. This is to provide a better understanding of the insert's structure. Figure 9 This is a schematic diagram of the structure consisting of a single stiffener 7C3 and a clamping plate 7C4. Figure 10 A cross-sectional schematic diagram of the display insert mounting structure. Figure 13 This is a schematic diagram of the cross-sectional structure of the insert. As shown in the figure, in this example, an insert 7C is also provided for insertion into the slot 7C12 and forming a fixed structure. The insert 7C has a pressure plate 7C4, on which ribs 7C3 are arranged radially (i.e., radially from the roller) at intervals. The head of each rib 7C3 has a plug 7C32, and the outer side of its tail has a barb 7C31. The ribs 7C3 also have a pressing surface 7C33 that forms a pressing surface with the inner wall of the rim 1.3 for fixation. This invention suggests that the insert 7C can be manufactured by injection molding.

[0067] Figure 10As shown, in this example, the clamping plate 7C4 of the insert 7C is attached to the outer conical wall of the conical support tube 7A3, the plug 7C32 is inserted into the slot 7C12, the pressing surface 7C33 of the insert 7C is pressed and fixed to the inner wall of the rim 1.3, and the insert 7C is clamped and fixed to the outer conical wall of the conical support tube 7A3 by the binding strip 7D on the outside of the barb 7C31 (the binding strip can be an elastic rubber strip for binding).

[0068] After the tab is rolled up, it is inserted into the slot 7C12, and then the insert 7C is inserted on its outside. The tab surrounds the first port 1.31 of the wheel rim 1.3 and forms a conical bucket 5. The multiple encircling inserts 7C are tightened and fixed from the outside by the binding strip 7D at the barb 7C31 of the insert 7C, so that the tab is attached and fixed to the outer wall of the conical support tube 7A3.

[0069] When the tab is severely worn and needs to be replaced, simply untie the binding strip, remove the tab, and then pull out the worn tab for replacement.

[0070] This invention suggests that, in this example, to ensure the installation and fixation of the thin sheet and to give the opening 5_1 of the conical bucket 5 sufficient ground contact width, preferably, the depth to which the thin sheet 5.1 is inserted into the slot can reach 10-20 cm (or even more); the width of the thin sheet 5.1 extending beyond the end face of the first port 1.31 of the rim 1.3 can reach 40-50 cm; the diameter of the inner wall of the rim 1.3 can reach 0.7 m-1.0 m (or even more); the taper ratio of the conical bucket 5 (i.e., the difference in diameter of the two base circles divided by the height of the conical bucket) can preferably be between 1:1 and 1:1.3; and the opening diameter of the conical bucket 5 can reach 1.1 m-1.4 m (or even more). This invention suggests that the above parameters are only preferred parameters and not limitations.

[0071] This invention suggests that the bucket proposed in this embodiment is a shaftless bucket, with the rollers employing a shaftless and spokeless structure. During use, this effectively eliminates the obstruction caused by the roller spokes to the entry of waste into the bucket cavity. This increases the rolling speed of the bucket and improves cleaning efficiency.

[0072] Figures 14-16 This is a partial structural diagram of the second embodiment of the shaftless rolling bucket of the present invention. As shown in the figure, unlike the first embodiment, in this example, the sheet 5.1 is flattened into a planar fan-ring structure and then rolled up to form a partial conical bucket. The conical bucket 5 is assembled by rolling up the sheets 5.1, 5.2, 5.3, 5.4, 5.5, and 5.6. Figure 4 , Figure 5The display shows that one side of the fan-ring structured sheet 5.1 has a step 5.1A, thereby making the angle corresponding to the outer arc of the fan ring greater than the angle corresponding to the inner arc. Multiple sheets are assembled around each other to form a complete conical bucket, with adjacent sheets overlapping at the junctions, such as... Figure 3 Section 5.1.2.

[0073] This invention suggests that the sheet constituting the flap should have sufficient rigidity to allow it to recover its shape after being deformed by external force (rigidity is the ability of an object to maintain its shape). The invention also suggests that the sheet can be punched and cut from a metal or plastic sheet.

[0074] Figures 17-42 This is a schematic diagram of the structure of the third embodiment of the present invention. This example is an embodiment of a vehicle-mounted ground sweeping device.

[0075] As shown in the figure, this example of a vehicle-mounted ground sweeping device consists of a shaftless roller. A rolling bearing 16 is also provided, with the shaft hole of the rolling bearing 16 and the wheel cavity of the wheel rim 1.3 forming an integrated wheel cavity.

[0076] It is also provided with a clasp arm 17, which has a body plate 17A and a left clasp arm 17B1 and a right clasp arm 17B2 extending forward from the left and right sides of the body plate 17A respectively. The ends of the left clasp arm 17B1 and the right clasp arm 17B2 respectively have a left palm plate 17B11 and a right palm plate 17B21 that are bent inward.

[0077] Preferred, Figure 20 The wheel rim 1.3, located on one side of the first port 1.31, also has a wheel rim flange 1.38, with flange mounting holes 1.381 provided on the wheel rim flange. The inner ring 16A of the rolling bearing 16 has an inner flange (with mounting holes on the inner flange), and the outer ring 16B of the rolling bearing 16 has an outer flange (with mounting holes on the outer flange). The inner ring 16A of the rolling bearing 16 is fixed to the wheel rim flange 1.38 via the inner flange. Corresponding flange mounting holes are provided on the left palm plate 17B11 and the right palm plate 17B21, respectively. The outer ring 16B of the rolling bearing 16 is fixed to the left and right palm plates of the arm 17 via the outer flange, thereby enabling the arm 17 to tightly fix the roller end from both sides of the wheel rim, like the two arms of a human body, and to position the opening of the conical bucket in front of the chest.

[0078] A frame 9 is also provided, which is installed behind the vehicle body 18 and towed by the vehicle. Unlike the tenth embodiment, in this example, the frame 9 is connected to the moving vehicle by a hinge (i.e., articulated) and its hinge is parallel to the vehicle's driving wheel axle. The vehicle tows the frame 9 together, and the rollers touch the ground under the action of gravity. When the vehicle is moving, the rollers roll close to the ground and follow the vehicle (since the rollers roll along the ground, no sliding friction is generated between the tassels and the ground).Figure 31 , 32 As shown, the frame 9 is hinged to the bracket 18A on the body 18 via hinge 3.37 on the bracket 9.13. The arm 17 is mounted on the frame 9 via the body plate 17A, and the central axis of the rolling bearing 16 is parallel to the vehicle's driving wheel axle, allowing the bucket to move with the vehicle. Figure 23 , Figure 24 , Figure 29 , Figure 34 As shown, the arm 17 is mounted on the bracket 9.1 of the frame 9 via the body plate 17A.

[0079] A first blower 10.1 is also provided. The first blower 10.1 is installed and fixed by the frame 9 and its air outlet faces the opening 5_1 of the conical bucket. The air blown out by the first blower 10.1 blows close to the ground and blows the garbage on the ground into the opening 5_1 and then discharges it from the garbage outlet. Figure 33 , Figure 34 As shown, in this example, as a preferred embodiment, a second blower 10.2 is also provided, which together with the first blower 10.1 form a relay blower.

[0080] Figures 35-42 As shown, in this example, a garbage collection device 19 is also provided. The garbage collection device 19 includes a garbage collection pipe 19.0, which has a garbage inlet 19.1 and a garbage outlet 19.2. The garbage inlet 19.1 is close to and aligned with the garbage discharge outlet facing the hopper. The garbage outlet 19.2 is located at the rear of the frame 9. The garbage collection pipe 19.0 is mounted on the frame 9. The garbage inlet 19.1 matches the garbage discharge outlet of the hopper to receive garbage (the garbage collection pipe is not fixed to the hopper, so the garbage collection pipe is fixed when the hopper rotates). A collection bag 23 is also provided at the garbage outlet 19.2. The garbage collection pipe 19.0 also serves as a garbage conveying pipe. After the garbage is discharged from the garbage discharge outlet of the hopper, it enters the garbage collection pipe 19.0 and finally falls into the collection bag 23 through the garbage discharge outlet 19.2. The diagram shows that the garbage collection pipe 19.0 is a square tube structure (made with angle iron as the skeleton and wrapped with thin iron sheet, similar to the ventilation pipe structure of a building). Figure 36 The waste collection pipe 19.0 is shown to have four sealing plates: a front plate 19A, a bottom plate 19B, a top plate 19C, and a rear plate 19D. The waste inlet 19.1 is located on the front plate 19A at the front end of the pipe, and the waste outlet 19.2 is located on the front plate 19A at the rear end of the pipe. A flow guide baffle 20 is also installed within the pipe. Figure 35As shown, the baffle 20 is installed at the end of the pipe and forms an obtuse angle with the direction of vehicle travel (an obtuse angle is an angle greater than 90° and less than 180°). The garbage moves towards the tail end in the pipe cavity and is guided to the garbage outlet 19.2 when it collides with the baffle 20. Figure 41 The image shows that a collection bag support plate 9.3 is also installed on the frame 9, and the collection bag 23 is placed on the support plate 9.3.

[0081] As a preferred option, Figure 36 As shown in the figure, in this example, the front and end heads of the garbage collection pipe 19.0 are open structures, and the garbage collection pipe 19.0 has a wind inlet 19.3 located at the front end of the pipe body and a wind outlet 19.4 located at the end of the pipe body. Figures 35-38 The display shows that ventilation holes 20.1 are also arrayed on the baffle plate 20. The air inlet 19.3 at the front end of the pipe, the ventilation holes 20.1 on the baffle plate, and the air outlet 19.4 at the rear end of the pipe form convection, accelerating the airflow in the pipe cavity. When the vehicle is in motion, a relative speed is generated between the vehicle body and the air. External air enters the garbage collection pipe from the air inlet 19.3, blowing the garbage in the pipe cavity toward the rear of the vehicle and causing it to fall into the collection bag 23. A sand discharge hole 19B1 is also provided on the bottom plate 19B of the pipe body. The sand blown into the pipe cavity is discharged through the sand discharge hole 19B1 during the movement of the pipe cavity.

[0082] Figure 36 , 39 As shown in the figure, in this example, as a preferred embodiment, semi-circular brackets 22 are provided on the upper and lower sides of the garbage outlet 19.2, which are used to open and fix the opening of the collection bag 23.

[0083] Preferred, Figures 35-41 The invention also includes a lifting device for the garbage collection pipe 19. This lifting device comprises a frame 21, with a long support 21.1 on its upper side. The long support 21.1 is hinged to the frame's support 9.11 via a hinge 3.38. The front end (head) of the garbage collection pipe 19 is placed on the frame 9, while the bottom of the garbage collection pipe 19 is fixed to the frame 21 (the fixation between the bottom of the garbage collection pipe 19 and the frame 21 can be achieved by bolts or welding). The garbage collection pipe 19 rotates around the hinge 3.38, causing its head to lift. The invention suggests that the function of the long support 21.1 is to increase the installation distance between the hinges, thereby ensuring that the garbage collection pipe 19 does not wobble during the rotation and lifting process.

[0084] Figure 42 This is a structural diagram for waste disposal. The diagram shows that, because hinge 3.38 is located on the upper side of the frame 21 at the tail end of the waste collection pipe 19 (when the waste collection pipe 19 is in a flat position), the waste collection pipe 19 wraps around hinge 3.38.

[0085] With the hinge axis rotating upwards, the head of the garbage collection pipe 19 is lifted upwards, and the garbage accumulated inside the pipe is poured into the collection bag 23 through the garbage outlet 19.2. This invention suggests that the lifting methods for the garbage collection pipe 19 include: manual lifting, gas spring-assisted lifting, or lifting driven by an electric push rod or pneumatic piston.

[0086] During the operation of the garbage sweeper, the vehicle body 18 moves together with the tractor frame 9, and the bucket rolls close to the ground. The sweeper continuously blows garbage from the ground into the bucket. After entering the garbage collection pipe 19.0, the garbage moves towards the rear of the pipe under the action of the wind and finally falls into the collection bag 23. When the collection bag 23 is full of garbage, a new collection bag can be replaced (the collection bag can be a regular plastic garbage bag).

[0087] Figures 23-27 , Figure 31 , Figure 32 As shown in the figure, as a preferred embodiment, in this example, a support mechanism 14.1 for driving the frame 9 to lift is also provided. The support mechanism 14.1 is installed on the lower side of the frame 9 and consists of a support frame 14.2 and a linear drive mechanism.

[0088] In this example, the support frame 14.2 is a T-shaped structure composed of brackets 14.21 and 14.22. Bracket 14.21 can be made of angle iron, and bracket 14.22 can be made of channel iron, which are welded together to form the T-structure. The linear actuator is an electric push rod 15 (or a cylinder piston). The proximal end of bracket 14.22 of the support frame 14.2 is fixed to bracket 18A of the vehicle body 18 via hinge 3.36 on bracket 14.21. Preferably, the brackets constituting the frame 9 can be made of square steel, and the frame 9 is welded from square steel.

[0089] A first mounting base 14.2A is provided at the far end of the bracket 14.22. A first pin 14.2A1 is provided on the first mounting base 14.2A and a support wheel 14.3 is mounted on the pin. The support wheel 14.3 is located on the lower side of the bracket 9.1.

[0090] Figure 23 , 24As shown in Figure 27, the fixed end 15.1 of the electric push rod 15 is mounted on the bracket 18B of the vehicle body 18, while the rod end 15.2 of the drive rod is mounted on the lower side of the distal end of the bracket 14.22. Thus, the electric push rod 15 can drive the support frame 14.2 to rotate. When the electric push rod 15 is in the starting position, on a flat surface, the roller touches the ground under the action of gravity, and the bucket moves along with the vehicle. In this state, there is a gap 14.3A between the support wheel 14.3 and the lower surface of the bracket 9.1. The gap 14.3A allows the roller 1 to move up and down and bounce when traveling on uneven ground, while always remaining in contact with the ground (the gap 14.3A can be selected from 0-10 cm). When it hits an obstacle on the ground (such as a stone), the roller 1 can lift up, and when the ground becomes concave, the roller 1 can lower down (the roller can rise freely when it hits an obstacle on the ground, which can avoid the impact of the obstacle on the roller).

[0091] In this example, the support frame 14.2 is lifted by the electric push rod 15, and the support wheel 14.3 lifts the frame 9 from bottom to top, thereby lifting the bucket off the ground (the bucket being lifted off the ground is activated when the vehicle passes over obstacles such as steps, when the vehicle turns, to avoid damage to the bucket's flaps, or when the vehicle is traveling straight but in non-purge mode).

[0092] In this example, the support mechanism 14.1 is located on the lower side of the frame 9, lifting the frame 9 to raise the bucket off the ground. This invention suggests that in other embodiments, the support mechanism 14.1 located on the lower side of the frame 9 can be replaced by a suspension mechanism located on the upper side of the frame 9. The suspension mechanism uses a traction method to lift the frame 9 via a soft rope, causing the frame 9 to rotate around a hinge and lift, thus raising the bucket off the ground. Furthermore, when using the suspension traction method, in the normal blowing mode of the sweeper, the soft rope connecting the suspension mechanism and the frame is slack, acting equivalent to the support wheel 14.3 and bracket 9.1 of the support mechanism.

[0093] The buffer gap 14.3A between the bottom surfaces is intended to allow the roller 1 to move up and down and bounce on uneven ground while always keeping it in contact with the ground.

[0094] In this example, Figure 30 , Figure 33 As shown, in this example, a pop-out pneumatic spring 15A is also installed on the left and right sides of the frame 9 (i.e., in the longest position when in the free state). Figure 32 This is a schematic diagram of the structure of the bucket lifting off the ground. The diagram shows that, driven by the supporting mechanism 14.1, the frame 9 rotates around the axis and lifts upward to lift the bucket off the ground. Figure 32As shown, the fixed end 15A.1 of the pneumatic spring 15A is mounted on the bracket 18B of the vehicle body 18, while the rod end 15A.2 is mounted on the bracket 9.12 of the frame 9. The function of the pneumatic spring 15A is to provide support and further reduce the driving force of the electric push rod 15. Provided that the opening 5_1 of the conical bucket 5 has sufficient ground contact width (the ground contact width is the length of the opening 5_1 of the bucket that is in contact with the ground along the direction of bucket travel, preferably 350-650 mm), only a small lifting force (preferably 50-150 N, where N is Newton) is needed to lift the frame 9 and lift the bucket off the ground; at the same time, it can reduce the damage to the frame 9 when it is struck by an obstacle.

[0095] Figures 43-45 This is a schematic diagram of the fourth embodiment of the present invention, which is also a schematic diagram of another preferred embodiment of the vehicle-mounted ground sweeping device. Unlike the third embodiment, this example also includes a cover 24 and a cover plate 25. The cover 24 is mounted on the upper side of the roller and covers the roller from top to bottom. The cover plate 25 is mounted on the upper part of the frame 9, and the sweeper is covered under the cover plate 25. One side of the cover 24 is mounted on the frame 9 via a hinge 3.39. The cover 24 can be opened when the blades need to be replaced. Furthermore, in this example, a traveling wheel 1-1 is also provided at the rear of the frame 9, on the other side of the roller. The present invention suggests that the cover 24 is preferably opened and closed with gas spring assistance.

[0096] This invention suggests that, in other embodiments, an in-pipe blower may also be provided. The in-pipe blower is installed and fixed on the garbage collection pipe. The blower nozzle is connected to the inside of the garbage collection pipe and blows the garbage inside the pipe, causing it to move towards the rear of the vehicle frame and finally fall into the collection bag.

[0097] This invention suggests that, in other embodiments, sweeping discs or blowers can be installed on the left and right sides of the front end of the frame to sweep garbage from the corners of the curb towards the middle of the road. This invention also suggests that, in addition to being positioned behind the vehicle body 18 and towed by the vehicle, in other embodiments, the frame 9 can also be positioned at the very front of the vehicle and pushed by the vehicle. When turning, traveling straight but in non-blowing mode, or crossing obstacles such as steps, the support mechanism 14.1 can lift the frame 9 to raise the bucket off the ground.

[0098] Figures 46-57 This is a partial structural diagram of the fifth embodiment of the present invention. This example provides a sweeping vehicle.

[0099] As shown in the diagram, the frame 9 in this example is a component of the body (moving vehicle) 18. The body 18 and the frame 9 together form a small car (such as a truck) with a rear frame.

[0100] Figure 46 ,Figure 47 As shown, in this example, the ground sweeping vehicle includes a moving vehicle 18, which includes a frame 9 (such as the rear frame of a truck); the traveling wheels 1-1 and 1-2 constitute the rear wheel set of the vehicle. During the movement of the vehicle, the front wheel set and the rear wheel set constitute the front and rear wheel sets of the vehicle.

[0101] Figures 48-57 As shown, in this example, a parallel four-bar linkage 13 is also provided. The parallel four-bar linkage 13 consists of an upper link 13.1A, a first vertical link 13.2A, a lower link 13.1B, and a second vertical link 13.2B. The links of the parallel four-bar linkage 13 are connected by hinges in sequence.

[0102] Figure 46 , 47 As shown in Figure 48, the parallel four-bar linkage mechanism 13 is installed under the belly of the vehicle 18, and the bucket is installed in the bucket installation space 9.41.

[0103] As shown in the figure, the second vertical rod 13.2B of the parallel four-bar linkage 13 is vertically mounted and fixed on the frame 9, and the operating plane of the parallel four-bar linkage 13 is perpendicular to the direction of vehicle movement (the second vertical rod 13.2B is the bracket 9.14; the operating plane of the parallel four-bar linkage is perpendicular to the connecting hinge pins between the rods). Since the second vertical rod 13.2B is fixed, during the operation of the parallel four-bar linkage 13, the upper link 13.1A and the lower link 13.1B rotate around their respective hinge pins connected to the second vertical rod 13.2B and always remain parallel to each other. Therefore, the first vertical rod 13.2A always remains vertical.

[0104] The first vertical rod 13.2A is the body plate 17A of the arm. The bucket is mounted on the parallel four-bar linkage 13 through the arm 17. The central axis of the rolling bearing 16 is always parallel to the wheel axle of the vehicle. Under the action of gravity, the roller 1 touches the ground. When the vehicle 18 is moving, the roller rolls along the ground. When the ground is uneven, the roller 1 rises and falls with the terrain under the control of the parallel four-bar linkage 13.

[0105] Figures 48-57 As shown, in this example, a support mechanism 14.1 is also provided to drive the parallel four-bar linkage mechanism to lift and lower. The support mechanism 14.1 is installed on the lower side of the parallel four-bar linkage mechanism 13. The support mechanism 14.1 consists of a support frame 14.2 and a linear drive device. In this example, the linear drive device is an electric push rod (or cylinder piston) 15.

[0106] The proximal end of the support bracket 14.2 is hinged to the frame bracket 9.14 via a hinge. A support wheel 14.3 is provided on the upper side of the distal end of the support bracket 14.2. Figure 49, 50 As shown in Figure 52, a lifting plate 13.1A1 is provided on the upper connecting rod 13.1A. The support wheel 14.3 is located on the lower side of the lifting plate 13.1A1 and there is a gap 14.3A between the support wheel and the lifting plate 13.1A1. The gap 14.3A allows the roller to move up and down and bounce when traveling on uneven ground and always stays on the ground.

[0107] Figure 50 , Figure 51 The electric push rod 15 is located on the lower side of the support frame 14.2. The electric push rod 15 drives the support frame 14.1 to rotate upward around the axis through the lifting plate 13.1A1, thereby raising the parallel four-bar linkage 13 and lifting the bucket off the ground.

[0108] As shown in the figure, in this example, the supporting mechanism 14.1 lifts the bucket off the ground by driving the parallel four-bar linkage 13.

A support mechanism is also provided to drive the parallel four-bar linkage mechanism to rise and fall. The support mechanism is installed on the lower side of the parallel four-bar linkage mechanism and consists of a support frame and a linear drive device, which is an electric push rod or a cylinder piston. The proximal end of the support frame is hinged to the body of the moving vehicle via a hinge. A support wheel is provided on the upper side of the far end of the support frame. A lifting plate is provided on the upper linkage. The support wheel is located on the lower side of the lifting plate and there is a gap between the support wheel and the lifting plate. The gap allows the roller to rise and fall and bounce when traveling on uneven ground, and always remain in a grounded state. The electric push rod is located on the lower side of the support frame. The electric push rod drives the support frame to rotate upward around the axis and lifts the parallel four-bar linkage mechanism and the bucket off the ground through the lifting plate.
