[0063] Figure 1-Figure 25 This is a schematic structural diagram of an embodiment of the road cleaning device proposed by the present invention.

[0064] The figure shows that in this example, a road cleaning device includes: a guide plate, which intercepts the garbage swept along the road surface and guides it to rise, the guide plate has a guide portion, the guide portion has a guide surface, and the guide surface is a curved surface or an inclined plane;

[0065] Preferably, in this example, the sweeper is an air blower, and the gas ejected by the air blower blows along the ground toward the drainage surface;

[0066] The storage container is arranged at the rear side of the guide plate with the vehicle's forward direction as the front, and the garbage inlet is facing the front. The rear end of the storage container is also provided with an air circulation hole. The road garbage moves toward the guide plate after being swept, and the garbage raised during the sweeping process and the garbage rising along the guide surface enter the storage container from the garbage inlet. Road cleaning device

[0067] The mounting frame 4A is used to mount and fix the guide plate and the air blower and allows the guide plate and the air blower to move with the vehicle.

[0068] Preferably, in this example, the guide plate is made of a hard thin sheet with elastic deformation properties, the lower side of the guide plate has a ground-contacting portion and the upper side has a rising portion, and a bumper plate is provided at the front end of the ground-contacting portion, the bumper surface of the bumper plate faces the front of the vehicle and forms an acute angle with the road surface.

[0069] The storage container also has a garbage outlet facing the rear of the vehicle.

[0070] Preferably, in this example, the storage container is a tube groove 1, which is a thin-walled square tube structure. The tube groove 1 has a tube cavity, and a first collecting groove 1.2B1 and a second collecting groove 1.2B2 are arranged at the outlet of the tube groove 1; air circulation holes are arranged on the rear side of the tube groove 1, and after the air enters the tube groove 1, it flows backward and finally flows out of the groove from the ventilation holes.

[0071] A reinforcement frame 1A made of metal profiles is also arranged on the outside of the pipe groove 1;

[0072] The mounting frame 4A is a frame structure, and the guide plate and the air purge are mounted on the mounting frame 4A.

[0073] Preferably, in this example, the guide plate includes a first lateral guide plate 2.1, and the first lateral guide plate 2.1 is arranged horizontally; (the front of the vehicle is pointed to the north, the left side of the vehicle is the west, the right side is the east, and the rear is the south; the longitudinal direction refers to the north-south direction, and the transverse direction refers to the east-west direction; the first lateral guide plate is arranged horizontally, which means that its guide surface faces the left or right side.)

[0074] Preferably, in this example, the air blower comprises a first air blower 3.1, the first air blower 3.1 and the first lateral guide plate 2.1 are installed side by side at the garbage inlet in a transverse direction, and the blowing port of the first air blower 3.1 faces the guide surface of the first lateral guide plate 2.1, and the first air blower 3.1 blows the garbage toward the first lateral guide plate 2.1;

[0075] A second lateral flow guide plate 2.2 is also provided and a second air blower 3.2 is correspondingly provided; the blowing port of the second air blower 3.2 blows the garbage toward the second lateral flow guide plate 2.2.

[0076] In this example, the first lateral guide plate 2.1 and the second lateral guide plate 2.2 are made of hard thin sheets with elastic deformation properties. This is mainly because during the driving of the vehicle, the ground-contacting portion that is in contact with the ground will hit raised obstacles on the road surface. To avoid damage, the elastic deformation of the first lateral guide plate and the inclined structure of the anti-collision surface are used to enable the ground-contacting portion to pass over the obstacle and then return to its original state, thereby enabling the first lateral guide plate to have an obstacle-crossing function in the longitudinal direction. Fig. 9 As shown, in this example, the second lateral guide plate 2.2 has a guide portion 2.2A, a ground-contacting portion 2.2B, and a rising portion 2.2C.

[0077] The anti-collision plate 2.2B1 is made of a metal sheet with elastic deformation properties, and the ground contacting portion 2.2B and the anti-collision plate 2.2B1 are welded to form an integrated structure.

[0078] The second lateral flow guiding plate 2.2 is mounted and fixed on the mounting frame 4A through the rising portion fixing holes 2.2C1, 2.2C2, and 2.2C3.

[0079] In this example, the first lateral guide plate 2.1 and the second lateral guide plate 2.2 are respectively arranged on the left and right sides in front of the transition groove inlet 1.11 and the guide surfaces face each other. The first air blower 3.1 and the second air blower 3.2 are arranged in the middle position in front of the transition groove inlet 1.11 and blow toward the left and right sides respectively and make the road surface enclosed by the first lateral guide plate 2.1 and the second lateral guide plate 2.2 within the blowing range.

[0080] As a preferred embodiment, in this example, the front of the pipe groove 1 is also provided with a transition groove 4, and the entrance of the transition groove 4 is provided with a forward guide plate 5, which is connected to the lower edge of the transition groove entrance 1.11, and the forward guide plate 5 has a forward guide surface and the forward guide surface faces the front of the vehicle, and the forward guide surface is an inclined plane with a lower front and a higher rear, and the angle between the forward guide surface and the road surface forms an obtuse angle; after being swept, the garbage rises from the transition groove entrance 1.11 into the transition groove 4, and then enters the pipe groove 1 through the transition groove exit 1.21 and the pipe groove entrance 1.12;

[0081] Combination Fig.19 The present invention indicates that the front guide plate 5 has an elastic deformation property, the vertical distance between the lower edge 5.12 of the front guide plate 5 and the road surface 1.10 is the ground clearance, and the distance from the lower edge 5.12 of the front guide plate along the front guide surface to the upper edge 5.11 should be less than the ground clearance. The front guide plate has an elastic deformation property so that it can restore its original shape after deformation. When encountering a raised obstacle on the road surface, the front guide plate bends backward to pass over the road obstacle and then restores its original shape.

[0082] The present invention suggests that the forward guide plate has an elastic deformation property so that it can restore its original shape after deformation. When encountering a raised obstacle on the road surface, the forward guide plate bends backward to pass over the road surface obstacle and then restores its original shape.

[0083] The present invention suggests that during the blowing operation, a part of the garbage on the road does not move close to the ground but is lifted up in the middle. The garbage lifted higher will enter the transition groove 4 from the transition groove entrance 1.11 and then enter the pipe groove 1, while the garbage lifted lower will touch the drainage surface of the forward guide plate 5 and be guided to rise and then enter the pipe groove 1 after passing through the transition groove 4; the forward guide plate 5 also guides more air into the pipe groove 1, thereby enhancing the blowing of the garbage in the pipe groove 1 and accelerating its flow to the rear.

[0084] Preferably, in this example, a check plate 7 is further provided in the pipe groove 1. The check plate 7 is provided in front of the groove openings of the first collecting groove 1.2B1 and the second collecting groove 1.2B2. The check plate 7 forms an acute angle with the bottom of the pipe groove. The check plate 7 allows the garbage in the groove cavity to enter the collecting groove only in one direction.

[0085] The present invention suggests that the check plate 7 is made of a hard sheet, which has elastic deformation properties and can return to its original shape after deformation; when the air is blown or the pipe groove is lifted, the garbage in the front end of the pipe groove can pass over the check plate and enter the rear end area of ​​the groove cavity, and when the pipe groove is flat, the check plate 7 can prevent the garbage in the rear end of the groove cavity from flowing back to the front end of the groove cavity. The check plate 7 can be made of a metal sheet or a PVC hard sheet.

[0086] As a preferred embodiment, in this example, a gravity confinement door 6 is further arranged at the rear end of the mounting frame 4A. The gravity confinement door 6 is composed of a door shaft 6.2 and a door plate 6.1 mounted on the door shaft 6.2. The size of the door plate 6.1 matches the groove cavity cross section of the pipe groove 1. The door shaft 6.2 is installed horizontally, and the door plate 6.1 is fixed on the door shaft 6.2 and the door shaft 6.2 is located in the middle of the door plate 6.1.

[0087] Axle seats 6.3A and 6.3B for mounting the door shaft 6.2 are respectively arranged on the left and right side walls at the rear end of the mounting frame 4A. The door shaft 6.2 is installed in the axle seats in a horizontal state. A plurality of through holes, i.e., material reduction holes 6.11, are also arranged on the upper door panel of the door shaft 6.2 (the through holes have two functions: to reduce the weight of the upper door panel of the door shaft, and to reduce the air resistance of the upper door panel of the door shaft when the vehicle is driving, so that the door panel can be automatically opened under the action of the flowing air).

[0088] A limit block 6.4 is also provided, and the limit block 6.4 is provided on the left and right side walls of the rear end of the mounting frame 4A. Since the weight of the door panel below the door shaft 6.2 is greater than the weight of the door panel above the door panel, when the vehicle stops running or decelerates or stops suddenly during driving, the door panel is in a limited state under the action of its own gravity and the slot cavity is closed in this state. The function of the gravity confinement door is to prevent the garbage in the slot from falling out of the garbage port due to the action of inertia when the vehicle decelerates or stops suddenly during driving.

[0089] The present invention suggests that in other embodiments, the storage container can also be replaced by a net bag instead of a square tube and a shaped bracket for supporting the net bag is provided; the garbage inlet of the net bag is installed at the rear end of the mounting frame 4A to receive the garbage.

[0090] Preferably, in this example, a first collecting tank 1.2B1 and a second collecting tank 1.2B2 are provided at the tube tank outlet 1.22, and the first collecting tank 1.2B1 and the second collecting tank 1.2B2 are installed in the cavity 1A11.

[0091] The first collecting trough 1.2B1 and the second collecting trough 1.2B2 respectively have a collecting cavity and a notch. The first collecting trough 1.2B1 and the second collecting trough 1.2B2 are built into the pipe trough outlet 1.22 in a drawer-like manner and the notch faces the garbage inlet. After the road garbage enters the pipe trough 1, it moves backward and finally enters the collecting trough. When the garbage in the collecting trough accumulates to a certain extent, the collecting trough is pulled out to dump the garbage.

[0092] The present invention suggests that in order to improve the air circulation effect of the tube trough 1 and reduce its own weight, the tube trough 1 and the first collecting trough 1.2B1 and the second collecting trough 1.2B2 can all be made of a perforated plate or a metal mesh. The perforated plate is a perforated plate formed by densely punching through holes on the plate, so that air can flow through the surrounding groove walls of the collecting trough.

[0093] Fig.26 , Fig. 27This is a schematic diagram of the structure of another embodiment of the road cleaning device proposed by the present invention. The figure shows that, unlike the first embodiment, in this example, a collection tank is not provided at the pipe groove outlet 1.22, but a movable door 1.2A is provided. The door leaf 1.2A1 of the movable door is installed at the garbage outlet through hinges 8.12 and 8.13, and the hinge is located on the upper side of the garbage outlet. Ventilation holes are provided on the door leaf of the movable door, and a stopper 1.2A2 is also provided. Buckles 1.2A31 and 1.2A32 that cooperate with the stopper are also provided on both sides of the door. Inserting the stopper can close the door leaf, and removing the stopper can open the movable door. During the operation, road garbage enters the pipe cavity of the pipe groove 1, and after accumulating to a certain amount, the garbage can be discharged from the movable door.

[0094] Figure 28-39 The schematic diagram of the structure of an embodiment of the garbage sweeper proposed by the present invention shows that in this example, a garbage sweeper includes a vehicle and the above-mentioned road sweeping device, and the road sweeping device is installed at the rear of the vehicle and travels with the vehicle.

[0095] Preferably, in this example, the sweeper is an air blower;

[0096] Preferably, in this example, the vehicle is a two-axle four-wheel structure, and the vehicle includes vehicle running wheel sets 9.11 and 9.12. The vehicle also has a rear end trailer; the rear end trailer is provided with a running wheel set, and the rear end trailer is connected or articulated with the front end traction part;

[0097] As a preference, in this example, the rear end dragging portion is a hollow carrier frame 9.2, and the road cleaning device is installed in the hollow of the carrier frame 9.2;

[0098] Fig.33 , Fig.38 It is shown in the figure that a crossbar 9.20 is arranged in the middle of the carrier 9.2 and the cavity is divided into a front cavity 9.21 and a rear cavity 9.22. In this example, the mounting frame 4A and the tube slot 1 are separated structures. The mounting frame 4A is arranged in the front cavity 9.21 and is connected to the crossbar 9.20 through a hinge (hinges 8.7, 8.8); the tube slot 1 is arranged in the rear cavity 9.22 and is connected to the rear end of the carrier 9.2 through a hinge (hinges 8.5, 8.6);

[0099] A transition groove 4 is also provided between the mounting frame 4A and the pipe groove 1 . Fig.34 It is shown that the transition groove 4 is installed on the lower side of the cross bar 9.20 through the fixed top plates 4.21 and 4.22; the junction between the transition groove 4 and the pipe groove 1 has a chamfer 4.3 that matches each other; Fig.34 and Figure 37-Figure 39As shown, in this example, the forward guide plate 5 and the transition groove 4 are of a split structure, and the forward guide plate 5 is mounted and fixed on the crossbar of the mounting frame 4A through the top mounting surface 5.2;

[0100] The present invention suggests that, in order to enhance the purging effect, the chassis of the vehicle is higher than the bottom of the tube groove so that the air flowing through the chassis when the vehicle is running can enter the tube groove;

[0101] Fig.29 , Fig.33 As shown, in this example, electric push rods 10.1 and 10.2 are also provided. The electric push rod 10.1 drives the mounting frame 4A to rotate around the rear end hinge shaft (i.e. hinges 8.7 and 8.8) to raise the mounting frame 4A and components such as the lateral guide plate, the forward guide plate and the air blower; the electric push rod 10.2 is used to drive the pipe trough 1 to rotate around the rear end hinge shaft (i.e. hinges 8.5 and 8.6) to raise the front end so that the garbage in the pipe trough 1 is discharged into the collection trough.

[0102] In the operation mode, the vehicle keeps moving forward while the air blower keeps blowing. After the garbage on the road is blown, part of it moves toward the lateral guide plate, is intercepted when it touches the lateral guide plate and is guided to rise and then enter the pipe groove 1 through the transition groove 4. At the same time, another part of it rises upward during the movement. Since the vehicle will move forward for a distance during the process of the garbage rising, the higher-raised garbage will enter the pipe groove 1 through the transition groove 4, and the lower-raised garbage will touch the forward guide surface 5.1 of the forward guide plate 5 and be guided to rise and then enter the pipe groove 1 through the transition groove 4.

[0103] When the vehicle needs to turn, the control mounting frame 4A is raised, so that the first lateral guide plate, the second lateral guide plate, the front guide plate and the air blower and other components are raised; when garbage needs to be dumped, the control pipe slot 1 is raised to discharge the garbage in the pipe slot 1 into the collection tank.

[0104] It should be noted that since it takes time for the garbage to be blown to the lateral guide plate, and the vehicle is constantly moving forward, the garbage will fall at the rear end of the lateral guide plate when it reaches the guide plate.

[0105] Figure 40-42 This is a structural schematic diagram of another embodiment of the garbage sweeper proposed by the present invention. The figure shows that, different from the previous embodiment, the garbage sweeper proposed in this example is further provided with a front garbage gathering component 13, a third air blower 3.3 and a corresponding third side guide plate 2.3.

[0106] In this example, the front garbage gathering component 13 includes a first garbage gathering component 13.1, which includes a first air blower 3.1, a fixing rod 13.11 and a baffle cloth 13.12 fixed to the lower side of the fixing rod 13.11. The first garbage gathering component 13.1 is installed on the lower side of the chassis of the vehicle through the fixing rod 13.11 and the bottom of the baffle cloth 13.12 touches the ground. In this example, as a preferred embodiment, a second garbage gathering component 13.2 is also provided.

[0107] In this example, the first air blower 3.1 and the second air blower 3.2 are moved forward and installed in front of the vehicle, and the third air blower 3.3 and the third side air guide plate 2.3 are fixedly installed on the mounting frame 4A.

[0108] The figure shows that when the first air blower 3.1 blows to the right, the garbage on the ground is blocked by the flow blocking cloth 13.12 (part of the garbage may pass over the flow blocking cloth 13.12); similarly, when the second air blower 3.2 blows to the left, the garbage on the ground is blocked by the flow blocking cloth 13.22 (part of the garbage may pass over the flow blocking cloth 13.22). As a result, the garbage on the ground is gathered inside the gathering area 13.30, which is located on the right side of the third air blower 3.3 and on the left side of the third lateral guide plate 2.3.

[0109] The third air blower 3.3 blows the garbage gathered in the gathering area 13.30 toward the third lateral guide plate 2.3, and the garbage is guided upward and then enters the pipe groove 1 through the transition groove 4.

[0110] The present invention suggests that the baffle cloths 13.12 and 13.22 can be made of wear-resistant canvas or soft plastic sheets.

[0111] Figure 43-49 This is a structural schematic diagram of another embodiment of the garbage sweeper proposed by the present invention. The figure shows that, unlike the previous embodiment, the garbage sweeper proposed in this example does not have a carrier frame 9.2, and the purge device is directly hinged to the vehicle through the front mounting frame 4A.

[0112] In this example, the mounting frame 4A is arranged at the front, and the pipe trough 1 is arranged at the rear. The mounting frame 4A and the reinforcement frame 1A of the pipe trough 1 are connected by a hinge (hinge 8.11) to form a two-section foldable structure, and the hinge is arranged at the bottom of the inter-section connection port; the transition trough 4 is installed at the front end of the pipe trough 1 to form an extension section, and the extension section is inserted into the mounting frame 4A. When the mounting frame and the reinforcement frame are folded and lifted at the connection, the extension section is lifted upward to guide the garbage therein to move toward the rear end of the pipe trough.

[0113] The mounting frame wheel set 9.61 and the tube groove 1 are respectively provided with the mounting frame wheel set 9.62, the mounting frame 4A is installed at the rear end of the vehicle and is hinged to each other, and its hinge axis is parallel to the running wheel axis of the wheel, and the hinge axis (hinge 8.9, 8.10) is arranged on the upper side of the front end of the mounting frame 4A, and the vehicle 9 pulls the road cleaning device to travel along the road surface;

[0114] In this example, an electric pulling system 11 is also provided, and the suspension rope 11.1 of the electric pulling system 11 is connected and fixed to the mounting frame 4A and drives the mounting frame 4A to rotate around the front hinge shaft (hinge 8.9, 8.10) and drives the mounting frame 4A and the pipe trough 1 to fold and lift at the middle connection so that the pipe trough 1 discharges garbage to the collection trough at the rear end. In order to further reduce the pulling force required for folding, during the folding process, the walking wheel set 9.52 of the reinforced frame is always on the ground and rolls along the ground.

[0115] In this example, a clamping device 12 is also provided, and the clamping device 12 includes a clamping body 12.0, a left clamping arm 12.1, and a right clamping arm 12.2. Guide wedges 12.11 and 12.21 are provided at the ends of the left clamping arm 12.1 and the right clamping arm 12.2, respectively; the left clamping arm 12.1 and the right clamping arm 12.2 are in an open state, and the width of the open state matches the width of the mounting frame 4A, and the clamping device is fixed to the vehicle frame through the clamping body 12.0. When the mounting frame 4A and the reinforced frame 1A are lifted and folded, the mounting frame 4A is placed between the left clamping arm 12.1 and the right clamping arm 12.2. The left clamping arm and the right clamping arm clamp the mounting frame, which can further ensure the stability of the mounting frame and the reinforced frame in the folded state, and avoid large shaking when the vehicle turns.

[0116] In this example, when the vehicle needs to turn or dump garbage, an electric pulling system 11 is provided to drive the mounting frame to rotate and lift, and drive the mounting frame and the reinforcement frame to fold and lift at the middle connection so that the pipe trough can dump garbage into the collection trough at the rear end.

[0117] The present invention suggests that the mounting frame and the reinforced frame of the road cleaning device are connected by a hinge shaft to form a two-section foldable structure. When folded, the body length of the garbage truck can be shortened, so that the vehicle has a smaller turning radius and is suitable for operation on narrower roads.

[0118] The present invention suggests that in other embodiments, a water mist spray device for dust removal is also provided, and the nozzle of the water mist spray device is installed at the rear end of the road sweeping device, so as to form a mist curtain around the rear end of the vehicle. During the cleaning process, air enters the pipe groove and then flows out from the air circulation hole. The dust therein combines with the water mist to form water droplets that fall to the ground, thereby achieving dust removal.

[0119] The garbage sweeper proposed by the present invention is particularly suitable for flat roads such as asphalt roads or cement roads, and has high working efficiency and energy efficiency.
