Description

Technical Field

[0001] The present invention relates to the technical field of road sweeping vehicles, and more specifically, the present invention relates to a small-sized road sweeping vehicle for municipal roads. Background Art

[0002] A road sweeping vehicle is an efficient cleaning device that integrates road surface cleaning, garbage collection, and transportation. Through four sweeping brushes, it can complete the cleaning, washing, and watering of the ground and the roadside curbs. It is suitable for cleaning operations in various climates and on different dry road surfaces. At present, many plane trees are planted on both sides of municipal roads. They have a high survival rate of transplantation, are resistant to barrenness, are easy to breed, have a long lifespan, grow rapidly, and are easy to prune into shape. The branches of the plane trees are pruned manually to extend towards the center of the road, acting as a huge sunshade in summer and playing a role in shading.

[0003] The plane tree is a deciduous tree. Every autumn, a large number of leaves fall. The roads and the lawns beside the roads are covered with leaves. At present, there is no special sweeping vehicle for efficiently cleaning leaves. Generally, it relies on manual cleaning, which has a large workload. Moreover, due to strong winds in autumn, it is even more inconvenient to clean. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a small-sized road sweeping vehicle for municipal roads, which can quickly clean the fallen leaves on the road.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A small-sized road sweeping vehicle for municipal roads includes a vehicle body and a leaf suction mechanism arranged at the bottom of the vehicle body. A leaf collection mechanism is arranged inside the vehicle body. The leaf collection mechanism includes a transfer box. The upper end and the lower end of the transfer box are respectively provided with a leaf inlet and a leaf outlet. A push leaf plate is slidably connected inside the transfer box. Above the leaf outlet, a leaf pressing member is movably inserted into the transfer box. At the bottom end of the leaf outlet, a flexible packaging member for storing garbage is installed. The leaf suction mechanism sucks the garbage into the transfer box through the leaf inlet, then the push leaf plate pushes the garbage into the leaf outlet, and finally the leaf pressing member presses the garbage into the flexible packaging member.

[0007] Preferably, the leaf collection mechanism further includes a driving component. The driving component includes a cam, a motor for driving the cam to rotate, and a connecting rod. One end of the connecting rod is rotatably connected to the edge position of the cam, and the other end of the connecting rod is hinged to the push leaf plate.

[0008] Preferably, the driving component further includes a swing rod and a pull rod. One end of the swing rod is located at the bottom end of the cam. A long slot is provided at the other end of the swing rod. The bottom end of the pull rod is inserted into the long slot. The upper end of the pull rod is fixedly connected to the upper end of the leaf pressing member. The swing rod is rotatably connected to the vehicle body through a rotating shaft.

[0009] Preferably, the leaf suction mechanism includes a leaf suction machine and a leaf suction pipe disposed on the front side of the bottom of the vehicle body, and a hair dryer disposed on the rear side of the bottom of the vehicle body. The inlet of the leaf suction machine faces the lower rear side of the vehicle body. The leaf suction pipe communicates with the outlet of the leaf suction machine and the leaf inlet. The air outlet of the hair dryer faces the lower front side of the vehicle body.

[0010] Preferably, a limit sleeve is fixedly installed inside the vehicle body. A movable rod is movably inserted into the limit sleeve. The upper end of the movable rod slides inside the swing rod. The bottom of the movable rod is hinged with a shovel blade member through a return spring. The bottom end of the movable rod faces the lower front side of the vehicle body. The shovel blade member is located between the leaf suction machine and the hair dryer.

[0011] Preferably, the shovel blade member is a toothed plate or a brush plate.

[0012] Preferably, a first spring is disposed at the bottom of the swing rod near the long groove. The two ends of the first spring are respectively connected to the vehicle body and the swing rod.

[0013] Preferably, the upper end of the leaf pushing plate has a leaf blocking portion. When the leaf pushing plate pushes the garbage towards the leaf outlet, the leaf blocking portion blocks the leaf inlet.

[0014] Preferably, a fixing mechanism is further included. The fixing mechanism includes an annular plate movably sleeved outside the leaf outlet. A plurality of pressing columns are fixedly connected to the circumferential direction of the bottom of the annular plate. A plurality of grooves corresponding to the pressing columns are opened on the upper surface of the bottom of the leaf outlet.

[0029] Embodiment

[0030] As Figures 1 to 6 shown, this embodiment provides a small municipal road sweeper for cleaning road surface garbage. It includes a vehicle body 1 and a leaf suction mechanism 2 arranged at the bottom of the vehicle body 1. A leaf collection mechanism 3 is arranged inside the vehicle body 1. The leaf collection mechanism 3 includes a transfer box 31. The upper end and the lower end of the transfer box 31 have a leaf inlet 311 and a leaf outlet 312 respectively. A push leaf plate 32 is slidably connected inside the transfer box 31. Above the leaf outlet 312, there is a leaf pressing member 33 that is movably inserted into the transfer box 31. At the bottom end of the leaf outlet 312, a flexible packaging member for storing garbage is installed. The leaf suction mechanism 2 sucks the garbage into the transfer box 31 through the leaf inlet 311, then the push leaf plate 32 pushes the garbage into the leaf outlet 312, and finally the leaf pressing member 33 presses the garbage into the flexible packaging member. Among them, the flexible packaging member can use ordinary plastic bags, but it is preferably a mesh bag.

[0031] In this embodiment, the leaf collection mechanism 3 further includes a driving member 34. As Figure 4 shown, the driving member 34 is used to drive the horizontal movement of the push leaf plate 32 and the vertical movement of the leaf pressing member 33. Specifically, the driving member 34 includes a cam 341, a motor 342 for driving the cam 341 to rotate, and a connecting rod 343. One end of the connecting rod 343 is rotatably connected to the edge position of the cam 341, and the other end of the connecting rod 343 is hinged to the push leaf plate 32. As Figure 4 shown, the motor 342 drives the cam 341 to rotate, and the cam 341 drives the push leaf plate 32 to move back and forth inside the transfer box 31 through the connecting rod 343 to push the garbage entering from the leaf inlet 311 towards the leaf outlet 312. The driving member 34 further includes a swing rod 344 and a pull rod 346. One end of the swing rod 344 is located at the bottom end of the cam 341. A long slot 345 is provided at the other end of the swing rod 344. The bottom end of the pull rod 346 is inserted into the long slot 345, and the upper end of the pull rod 346 is fixedly connected to the upper end of the leaf pressing member 33. The swing rod 344 is rotatably connected to the vehicle body 1 through a rotating shaft. As Figure 3As shown in the figure, a roller 347 is rotatably connected to the left end of the swing rod 344. The roller 347 contacts the outer surface of the cam 341. When the cam 341 rotates, it will drive the swing rod 344 to swing around the rotating shaft by pushing the roller 347. The swing rod 344 drives the pressing blade member 33 to move back and forth vertically through the pull rod 346, so that the garbage can be pressed into the flexible packaging member through the pressing blade member 33.

[0032] In this embodiment, the leaf suction mechanism 2 includes a leaf suction machine 21 and a leaf suction pipe 22 provided on the front side of the bottom of the vehicle body 1, and a hair dryer 23 and 24 provided on the rear side of the bottom of the vehicle body 1. The inlet of the leaf suction machine 21 faces the lower rear side of the vehicle body 1, and the leaf suction pipe 22 communicates with the outlet of the leaf suction machine 21 and the leaf inlet 311. The air outlet of the hair dryer 23 faces the lower front side of the vehicle body 1. As Figure 1 shown, the right side is the direction of the forward movement of this road sweeper. When moving forward, the leaf suction machine 21 sucks the road garbage and then discharges it into the interior of the transfer box 31 through the leaf suction pipe 22. Sometimes, the garbage may adhere to the road surface and it is difficult to be sucked away by the leaf suction machine 21. Therefore, the garbage blown by the hair dryer 23 onto the ground is blown away from the ground, so as to facilitate the leaf suction machine 21 to suck it away.

[0033] In this embodiment, due to the water on the road surface after rain or other reasons, the garbage cannot be sucked away by the leaf suction machine 21, and the hair dryer 23 cannot blow it up either. A limit sleeve 4 is fixedly installed inside the vehicle body 1. A movable rod 41 is movably inserted into the limit sleeve 4. The upper end of the movable rod 41 slides inside the swing rod 344. The bottom of the movable rod 41 is hinged with a shoveling blade member 42 through a return spring. The bottom end of the movable rod 41 faces the lower front side of the vehicle body 1, and the shoveling blade member 42 is located between the leaf suction machine 21 and the hair dryer 23. When the swing rod 344 swings, it can press down the movable rod 41, and the movable rod 41 drives the shoveling blade member 42 to shovel towards the ground, so that the garbage can be shoveled up. When the shoveling blade member 42 shovels towards the road surface, through the relative rotation with the movable rod 41, the shoveling blade member 42 can contact the road surface for a longer time, which is convenient for shoveling up the garbage. Different shoveling blade members 42 can be selected according to different situations. For example, when the road garbage is ordinary garbage, the shoveling blade member 42 can be selected as a brush plate, and when the road garbage is fallen leaves, a toothed plate can be selected.

[0034] In this embodiment, after the swing rod 344 is pressed down by the cam 341, in order to enable the swing rod 344 to quickly reset, a first spring 35 is provided at the bottom of the swing rod 344 close to the long slot 345. The two ends of the first spring 35 are respectively connected to the vehicle body 1 and the swing rod 344.

[0035] In this embodiment, the upper end of the pushing blade 32 has a leaf blocking portion 321. When the pushing blade 32 pushes the garbage towards the leaf outlet 312, the leaf blocking portion 321 blocks the leaf inlet 311. As Figure 4As shown, the baffle leaf part 321 can prevent the garbage entering from the inlet leaf 311 from falling to the right side of the pushing leaf plate 32 during the process of the pushing leaf plate 32 pushing the garbage into the outlet leaf 312.

[0036] In this embodiment, a fixing mechanism 5 is further provided. The fixing mechanism 5 includes an annular plate 51 movably sleeved outside the outlet leaf 312. A plurality of pressing columns 52 are fixedly connected in the circumferential direction at the bottom of the annular plate 51. A plurality of grooves 53 corresponding to the pressing columns 52 are formed on the upper surface of the bottom of the outlet leaf 312. A second spring 54 for resetting the annular plate 51 is arranged above the annular plate 51. The pressing columns 52 press down to fix the flexible packaging component on the outlet leaf 312. A placement area 11 for placing the flexible packaging component is arranged at the rear side of the vehicle body 1. The pressing leaf part 33 presses the garbage down into the flexible packaging component, and the flexible packaging component is placed at the position of the placement area 11.

[0037] Working principle:

[0038] (1) First, lift the annular plate 51 upward, put the packaging mesh bag on the bottom of the outlet leaf 312, and then release the annular plate 51. The annular plate 51 is pressed down by the second spring 54, so that the pressing columns 52 can press the packaging mesh bag on the outlet leaf 312, and the pressing columns 52 enter the grooves 53, which can effectively prevent the packaging mesh bag from slipping.

[0039] (2) Then the sweeper moves forward, blows the road surface through the blower 23 to blow up the garbage on the road surface, and then sucks the garbage from the suction leaf machine 21 into the inside of the transfer box 31 through the inlet leaf 311. The motor 342 drives the cam 341 to rotate, so that the swing rod 344 swings, and the swing rod 344 presses down the movable rod 41, so that the shoveling leaf part 42 can shovel up the garbage attached to the road surface and difficult to be blown up, so as to be sucked away by the suction leaf machine 21.

[0040] (3) The cam 341 drives the pushing leaf plate 32 to reciprocate through the connecting rod 343. The garbage entering the inside of the transfer box 31 is pushed into the outlet leaf 312 by the pushing leaf plate 32 and falls into the packaging mesh bag. The pressing leaf part 33 continuously reciprocates and presses down. Especially when the packaging mesh bag is full (the packaging mesh bag is not inflated or inflated less), by continuously pressing down the garbage by the pressing leaf part 33, the packaging mesh bag can be fully inflated, and the garbage fills the packaging mesh bag, achieving the purpose of garbage packing.

[0041] (4) According to the method in (1) above, remove the packaging mesh bag in the reverse direction, that is, complete one garbage cleaning, collection and packing.

[0042] It should be noted that in addition to cleaning ordinary garbage, this sweeper is mainly or especially suitable for cleaning fallen leaves. As described above, this sweeper cleans fallen leaves on the road surface. Moreover, this sweeper can also be used to clean fallen leaves on the lawn. When cleaning fallen leaves on the lawn, the blower 23 can effectively blow out the fallen leaves that are difficult to be sucked out of the grass, and then the leaf suction machine 21 sucks them away. The leaf shoveling part 42 can also use a toothed plate, so that the fallen leaves or broken branches can be shoveled out for easy suction.

[0043] Through the setting of the leaf collecting mechanism 3, on the one hand, the pusher plate 32 pushes the garbage into the mesh bag, and on the other hand, the pressing member 33 continuously presses down on the garbage, which can fully expand the mesh bag to be filled with garbage. Compared with the current method of only putting garbage into garbage bags, this method can make full use of the space of the mesh bag, pack more garbage each time, and also saves packaging bags. Through the setting of the leaf suction mechanism 2 and the leaf shoveling part 42, the blower 23 first blows up the garbage, the leaf shoveling part 42 shovels up the garbage, and then the leaf suction machine 21 sucks away the garbage, so it is not affected by the environment and can clean the road surface clean. It can not only clean flat roads, but also clean the lawn through the blowing of the blower 23 and the shoveling of the leaf shoveling part 42. The multi-scene application improves the practicability. Through the setting of the fixing mechanism 5, the packaging bag can be conveniently installed and disassembled. By placing the packaging bag at the position of the placement area 11, it is convenient to observe whether it is full.

[0044] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. It can be a mechanical connection or an electrical connection, or it can be the communication inside two components. It can be directly connected.
