[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0018] Reference Figure 1-2 As shown, an unmanned multi-functional leaf sweeper includes a vehicle body, a sweeping assembly at the front of the vehicle body cavity, and a material collection device in the middle of the cavity. The material collection device includes a material collection hopper 33 fixed in the vehicle body cavity, and a leaf baler 25 connected to the rear of the material collection hopper 33. The sweeping assembly includes a first lifting mechanism, a second lifting mechanism 2, a third lifting mechanism 3, and a bucket elevator 9. The first lifting mechanism, the second lifting mechanism 2, and the third lifting mechanism 3 are installed sequentially from front to back on the front side of the material collection hopper 33, and are respectively connected to two side brushes 4, horizontal collecting rollers 5, and a material collection shovel 6.

[0019] A horizontal fixed bracket 8 is fixed to the front side of the receiving hopper 33. The bucket elevator 9 is inclined between the third lifting mechanism 3 and the receiving hopper 33, with its upper end above the receiving hopper 33. A ring-shaped protective bracket 10 is sleeved on the fixed bracket 8 at its rear. Both sides of its lower end are provided with bearing wheels 11. Each bucket of the bucket elevator 9 is provided with a hook for hooking large fallen leaves and small branches on its outer edge. The rear of the receiving shovel 6 is hinged to the lower end of the bucket elevator 9. Ground-contacting wheels 7 are provided on its sides and middle part. Its side is connected to the bucket elevator 9 and the third lifting mechanism 3 respectively through the first buffer 12 and the second buffer 13.

[0020] More specifically, the bucket elevator 9 is suspended from the vehicle body by two third buffers 14 on both sides of the upper end. The first buffer 12, the second buffer 13 and the third buffer 14 are all elastic buffers; an emergency brake protector is installed on the second buffer 13.

[0021] The cleaning assembly also includes a spraying system, which includes a water pump 18, a spray pipe 34, and a water tank 17 fixed in the interior cavity of the vehicle. The water pump 18 is installed in the water tank 17, and its outlet is connected to the spray pipe 34 through a water pipe 19. The spray pipe 34 is horizontally positioned above the front side of the collecting roller 5, and its left and right ends are fixedly connected to the left and right ends of the mounting bracket of the collecting roller 5 through connecting rods.

[0022] The cleaning assembly also includes a suction mechanism installed between the bucket elevator 9 and the receiving hopper 33. The suction mechanism includes a fourth lifting mechanism 22, a suction cup 24, a vacuum pump, and a waste storage tank 20 fixed in the inner cavity of the vehicle body. The fourth lifting mechanism 22 is installed in the vehicle body, and its output end is connected to the suction cup 24 through a buffer 23. The vacuum pump is installed on the waste storage tank 20, and its inlet is connected to the suction cup 24 through a suction pipe 21, and its outlet is connected to the waste storage tank 20.

[0023] In addition, the vehicle is equipped with a retractable electronic screen 30, a camera 31, and lights 29, and detectors 32 are installed on both the front and rear sides. When the road traffic command center issues an instruction, the sweeper quickly arrives at the designated road section under the remote control of the staff. Warning information is displayed on the electronic screen 30, and obstacles are avoided by the detectors 32 during sweeping. The staff can observe the scene environment through the camera 31.

[0024] During the sweeping operation, the first lifting mechanism, the second lifting mechanism 2, and the third lifting mechanism 3 are activated, respectively driving the two side brushes 4, the collecting rollers 5, and the collecting shovel 6 to the ground; the fourth lifting mechanism 22 is activated, driving the suction cup 24 to descend; then the sweeper is manually remotely controlled to move forward, the two side brushes 4 rotate inward to gather fallen leaves and small branches towards the center, the collecting rollers 5 rotate to sweep the fallen leaves and small branches onto the bucket elevator 9 through the collecting shovel 6, the bucket elevator 9 then transports the fallen leaves and small branches into the collecting hopper 33 through the bucket and hook fork, and the suction cup 24 at the rear is responsible for sucking the remaining fine debris into the waste storage box 20; during the sweeping process, the spray system is activated, spraying water onto the ground through the spray pipe 34 to reduce dust; during the forward movement, the first buffer 12 and the second buffer 13 provide buffer for the collecting shovel 6, and the third buffer 14 provides buffer for the bucket elevator 9.

[0025] A rubber pad is installed at the front end of the collection shovel 6 to ensure its close contact with the ground during operation. The rubber pad also allows the collection shovel 6 to cross small, low, fixed obstacles, thereby improving the continuity and stability of the sweeping operation. When the collection shovel 6 hits a fixed obstacle, it will rotate counterclockwise and drive the bucket elevator 9 to shift obliquely upward with the cooperation of the annular protective bracket 10 and the fixed bracket 8, causing it to press against the third buffer 14. When the second buffer 13 is stretched beyond a certain limit or pressure, the emergency brake protector can send an emergency stop signal to stop the sweeper, thereby protecting the auxiliary accessories such as the first buffer 12, the second buffer 13, and the third buffer 14 from damage. Example 2

[0026] As a preferred embodiment of this utility model, this embodiment designs the first lifting mechanism based on Embodiment 1, specifically as follows: The first lifting mechanism includes a first lifter 1, a swing frame 15 and a horizontal adjustment bracket 16. The front end of the swing frame 15 is connected to the adjustment bracket 16, and the rear end is hinged to the bottom of the vehicle body. Two side brushes 4 are respectively installed at the left and right ends of the adjustment bracket 16. The main body of the first lifter 1 is hinged to the vehicle body, and its output end is hinged to the swing frame 15.

[0027] During operation, the output end of the first lifter 1 extends and drives the swing frame 15 to rotate downward, so that the two side brushes 4 touch the ground. Example 3

[0028] As a preferred embodiment of this utility model, this embodiment adds a material storage component based on embodiment one, specifically as follows: The rear of the vehicle body cavity is equipped with a storage assembly, which includes a storage bin 26 fixed in the vehicle body cavity. The storage bin 26 is located behind the leaf baler 25 and has an entrance on its front side. A gantry crane 27 is installed on the top of its inner cavity. The output end of the gantry crane 27 is connected to a lifting box 28 with an automatically opening and closing bottom. The lifting box 28 has an opening on its front side, and the outlet of the leaf baler 25 is located on the rear side and communicates with the entrance of the storage bin 26.

[0029] After the fallen leaves enter the leaf baler 25 through the receiving hopper 33, the leaf baler 25 bales the fallen leaves and sends the leaf bales into the storage bin 26 through the inlet. At this time, the front opening of the hoisting box 28 is close to the inlet of the storage bin 26, so the leaf bales entering the storage bin 26 will first enter the hoisting box 28. Then, the traversing mechanism 27 drives the hoisting box 28 to move in the storage bin 26 according to the set program. After it is in place, the bottom of the hoisting box 28 opens, allowing the leaf bales to fall into the designated position.

[0030] In summary, this device, controlled remotely by personnel, can effectively sweep and collect large areas of fallen leaves and small branches on the road surface through two side brushes 4, collecting rollers 5, collecting shovels 6 and bucket elevators 9. It can also clean up the remaining fine debris through suction cups 24. The storage component can pack, transport and store the collected fallen leaves, effectively increasing the amount of fallen leaves collected by this device, and also facilitating transportation operations.

[0031] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
