Description

Technical Field

[0001] This invention belongs to the field of environmental protection machinery technology, and in particular relates to a vehicle-mounted leaf handling device and method. Background Technology

[0002] With the continuous advancement of urbanization and the increasing demands for ecological civilization, the cleanliness of urban roads is becoming increasingly important. In northern regions during the autumn and winter seasons, the large amount of fallen leaves severely impacts road cleanliness. Currently, the cleaning of fallen leaves relies heavily on manual sweeping and collection by sanitation workers, followed by transportation to processing stations by environmental protection departments. As ordinary waste, centralized incineration is the primary method of disposal. It is evident that the current traditional methods of leaf collection and disposal not only consume significant manpower and resources and pollute the environment during burning, but also, due to the fluffy nature of leaves, their volume is 3 to 5 times that of ordinary waste for the same weight, resulting in relatively high transportation costs. Furthermore, it wastes the value of leaves as fertilizer.

[0003] The inventors discovered that, in order to solve the problems of traditional leaf disposal methods, they designed a vehicle-mounted leaf disposal device that integrates collection, crushing, and compression to collect and process fallen leaves, thus solving the problems of traditional leaf disposal methods. However, the current vehicle-mounted leaf disposal device is generally scattered and installed in the cargo compartment of a box truck, resulting in poor applicability. Furthermore, in actual leaf collection, the working area and flatness of the ground vary depending on the work location. For example, when collecting fallen leaves on sloping ground, the sweeping device on the existing leaf collection device cannot clean effectively and cannot adapt well to the specific requirements of the work location, resulting in poor leaf collection effect. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a vehicle-mounted leaf collection device and method. When the permissible working area and ground slopes are present, the working angles of the roller brush device and the two disc brushes can be adjusted using an angle adjustment device, and the working width of the two disc brushes can be adjusted by rotating the disc brush bracket using a rotation drive device. This adapts to the requirements of different working environments, ensuring the working area and angle of the roller brush device and disc brushes in the working area, thus guaranteeing the leaf collection effect.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a vehicle-mounted leaf handling device, including a housing, a collection mechanism provided on the outer side of the housing, and a crushing mechanism and a compression mechanism arranged sequentially from one end to the other inside the housing; the outlet of the crushing mechanism faces the inlet of the compression mechanism.

[0006] Furthermore, an extraction device is provided inside the box; the outlet of the extraction device is connected to the crushing mechanism through a pipe, and a flexible hose is provided at the inlet, with the end of the hose away from the extraction device located at the collection mechanism.

[0007] Furthermore, the angle adjustment device includes a telescopic device disposed on the side wall of the housing, the telescopic device being connected to the roller brush device via a hinge, the roller brush device being provided with a rotating shaft, and the telescopic rod of the telescopic device being connected to the rotating shaft.

[0008] Furthermore, the rotation drive device includes a first motor mounted on the roller brush device, and two pull rods connected to the first motor, with one end of each pull rod away from the first motor hinged to the disc brush bracket; a return spring is provided between the disc brush bracket and the roller brush device.

[0010] Furthermore, both the first and second cutting tools are cylindrical cutting tools.

[0011] Furthermore, the compression mechanism includes a rectangular frame, a pressure plate is provided on one side of the rectangular frame, a hydraulic cylinder is provided on the inner wall of the box, and the hydraulic cylinder is connected to the pressure plate; on the rectangular frame, a push plate and a baffle are provided on two sides adjacent to the pressure plate and perpendicular to the pressure plate; a third motor is provided on the upper part of the frame, a third gear is provided on the third motor, and a rack is provided on the push plate to mesh with the third gear.

[0012] Furthermore, an outlet is provided on the box body at the position of the baffle; the baffle includes a first baffle and a second baffle hinged to the rectangular frame; a first pulley is provided on the first baffle, a drive rod is provided on the second baffle, a second pulley is provided at the end of the drive rod away from the second baffle, and a second belt is connected between the first pulley and the second pulley.

[0013] Furthermore, a transmission device is connected to the end of the drive rod near the second baffle, and a roller is provided at the end of the transmission device away from the drive rod.

[0014] Secondly, the present invention also provides a vehicle-mounted leaf handling method, which employs the vehicle-mounted leaf handling device as described in the first aspect, including collecting the fallen leaves together using the collection mechanism, sending the collected fallen leaves to a crushing mechanism for crushing, and the crushed fallen leaves entering a compression mechanism for compression; during collection, the working angles of the roller brush device and the two disc brushes are adjusted by the angle adjustment device according to the area of ​​the working area and the ground slope, and the working width of the two disc brushes is adjusted by rotating the disc brush bracket through the rotation drive device.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] Example 1: The current vehicle-mounted leaf collection devices are generally scattered throughout the cargo compartment of box trucks, resulting in poor applicability. Furthermore, in actual leaf collection, the working area and flatness of the ground vary depending on the work location. For example, when collecting leaves on sloping ground, the cleaning devices on existing leaf collection devices cannot clean effectively and cannot adapt to the specific requirements of the work location, leading to poor leaf collection results.

[0021] In response to the above problems, such as Figure 1 and Figure 2As shown, this embodiment provides a vehicle-mounted leaf disposal device, including a housing 1. A collection mechanism 2 is provided on the outer side of the housing 1. A crushing mechanism 3 and a compression mechanism 4 are sequentially arranged from one end to the other inside the housing 1. The outlet of the crushing mechanism 3 faces the inlet of the compression mechanism 4. Figure 8 As shown, the box 1 is also equipped with an extraction device 5; the outlet 501 of the extraction device is connected to the crushing mechanism 3 through a pipe 503, and a hose is provided on the inlet 502. The end of the hose away from the extraction device is located at the collection mechanism 2, which is used to extract the collected fallen leaves into the crushing mechanism 3. like Figure 2 and Figure 3 As shown, the collection mechanism 2 includes a roller brush device 204, and an angle adjustment device is provided between the roller brush device 204 and the housing 1. Two disc brush brackets 207 are rotatably mounted at both ends of the roller brush device 204, and each disc brush bracket 207 is equipped with a disc brush 208. A rotation drive device is provided between each disc brush bracket 207 and the roller brush device 204. The angle adjustment device adjusts the working angle of the roller brush device 204 and the two disc brushes 208, and the rotation drive device adjusts the working width between the two disc brushes 208 by rotating the disc brush bracket 207.

[0022] The collection mechanism 2 is located on the outer side of the box 1, while the crushing mechanism 3 and the compression mechanism 4 are located inside the box 1. The overall structure is compact and can be fixed on existing small leaf sweepers, making it highly adaptable. When the working area is limited or the ground has a slope, the working angle of the roller sweeping device 204 and the two disc brushes 208 can be adjusted by the angle adjustment device, and the working width of the two disc brushes 208 can be adjusted by rotating the disc brush bracket 207 through the rotation drive device to adapt to the requirements of different working environments. This ensures the working area and angle of the roller sweeping device and disc brushes in the working area, guaranteeing the leaf collection effect.

[0023] The roller brush device 204 is designed to sweep fallen leaves into the air inlet of the hose to a certain extent, preventing some leaves from being left in place.

[0024] Optionally, the housing 1 can be a metal housing, which can be fixed to an existing leaf sweeper by welding or bolting. A crushing mechanism 3 and a compression mechanism 4 are sequentially arranged inside the housing 1 from one end to the other. It is understood that the crushing mechanism 3 is located at the upper end of the housing 1 during operation, and the compression mechanism 4 is located at the lower end. The leaves crushed by the crushing mechanism 3 can fall directly into the inlet of the compression mechanism 4 under gravity. The extraction device can be implemented using existing equipment such as a blower, exhaust fan, or pump. The roller brush device 204 and the disc brush 208 can both be implemented using existing equipment, which will not be detailed here. The disc brush bracket 207 is rotatably mounted on the roller brush device 204 via a shaft or bearing. The disc brush bracket 207 has three bent connecting rods connected to the disc brush 208.

[0025] In this embodiment, the angle adjustment device includes a telescopic device 201, such as a hydraulic telescopic rod or a pneumatic telescopic rod, which is installed on the side wall of the housing 1. The telescopic device 201 is connected to the roller brush device 204 through a hinge 202. The roller brush device 204 is provided with a rotating shaft 203, and the telescopic rod of the telescopic device 201 is connected to the rotating shaft 203.

[0026] Optionally, the hinge 202 includes two connecting rods, the two ends of which are rotatably connected to the telescopic device 201 and the roller brush device 204 via components such as pivots or pins. Specifically, the hinge 202 is connected to the upper end of the roller brush device 204 in its working state, and the pivot 203 is located at the lower end of the roller brush device 204 in its working state. When the telescopic rod on the telescopic device 201 drives the pivot 203 to move up and down, the roller brush device 204 rotates under the action of the hinge 202, thereby adjusting the angle of the roller brush device 204 and the disc brush 208 to meet the cleaning needs on ground with different slopes.

[0027] In this embodiment, the rotation drive device includes a first motor 205 mounted on the roller brush device 204, and two pull rods 206 connected to the first motor 205. The end of each pull rod 206 away from the first motor 205 is hinged to the disc brush bracket 207. A return spring is provided between the disc brush bracket 207 and the roller brush device 204.

[0028] Optionally, the two pull rods 206 are connected to the upper and lower sides of the output shaft of the first motor 205 respectively via connecting rods, so that when the output rod of the first motor 205 rotates, the two pull rods move in opposite directions; the two pull rods are respectively hinged to one end of the brush holder 207 via bearings or shafts. Specifically, when the first motor 205 rotates, the pull rods pull the two brush holders 207 to rotate. At this time, the two brushes 208 move outward, and the return spring is stretched, increasing the working width; when the first motor 205 is de-energized and stops rotating, the two brush holders 207 return to their original position under the tension of the return spring.

[0029] like Figure 4 , Figure 5 and Figure 6 As shown, the crushing mechanism 3 includes a crushing mechanism housing 302, a crushing mechanism inlet 301 and a crushing mechanism outlet opened at both ends of the crushing mechanism housing 302, a second motor 303 disposed on the outer wall of the crushing mechanism housing 302, a first gear 305 connected to the second motor 303 and rotatably disposed on the outer wall of the crushing mechanism housing 302, a second gear 306 meshing with the first gear 305 and rotatably disposed on the outer wall of the crushing mechanism housing 302, and a first cutter 307 and a second cutter 308 rotatably disposed inside the crushing mechanism housing 302; the first cutter 307 and the second cutter 308 are respectively connected to the first gear 305 and the second gear 306.

[0030] Optionally, the first gear is equipped with a pulley, and the output shaft of the second motor 303 is also equipped with a gear. A first belt 304 connects the two pulleys. Both the first cutter 307 and the second cutter 308 are cylindrical cutters. Specifically, when the second motor 303 rotates, it drives the first gear 305 and the second gear 306 to rotate, thereby causing the first cutter 307 and the second cutter 308 to rotate, thus crushing the fallen leaves.

[0031] In one or more embodiments, a cover 309 is provided on the pulverizing mechanism housing 302, and the pipe 503 passes through a through hole opened on the cover 309. The cover 309 is provided to prevent fallen leaves from flying out. A baffle 310 is provided on the cover 309. The baffle 310 can be inclined relative to the horizontal plane and is similar to a shovel-shaped device. The baffle 310 disperses the fallen leaves entering from the pipe 503, making the leaf distribution more uniform and improving the pulverizing effect.

[0032] In this embodiment, the dual-rotor meshing crushing mechanism, composed of two cylindrical cutters, is equipped with multiple blades on each cylindrical cutter, with a blade meshing gap of less than 2mm, ensuring that the cut leaves achieve the optimal compression standard. Based on the optimal compressed leaf particle size of 0.63-2mm, this embodiment reserves a blade meshing gap of 0.63-2mm. The crushed leaves are discharged into the rectangular housing of the compression mechanism by gravity through the leaf discharge port.

[0033] In this embodiment, as Figure 7 As shown, the compression mechanism 4 includes a rectangular frame. A movable pressure plate 402 is provided on one side of the rectangular frame. A hydraulic cylinder 401 is provided on the inner wall of the housing 1, and the hydraulic cylinder 401 is connected to the pressure plate 402. On the rectangular frame, a push plate 403 and a baffle are provided on two sides adjacent to the pressure plate 402, which are perpendicular to the pressure plate. A third motor 404 is provided on the upper part of the rectangular frame. A third gear 405 is provided on the third motor 404. A rack 406 that meshes with the third gear 405 is provided on the push plate 403. It can be understood that the hydraulic cylinder 401 can push the pressure plate 402 to compress the fallen leaves in the rectangular frame. After compression, the pressure plate 402 exits the rectangular frame. Driven by the third motor 404, the rack 406 drives the push plate 403 to push the compressed fallen leaves toward the baffle. Optionally, a crossbeam or other components for fixing the third motor 404 are provided on the upper part of the rectangular frame, and other positions on the upper part of the rectangular frame are open to allow fallen leaves to enter.

[0034] Optionally, the hydraulic cylinder 401 applies a pressure of 10 MPa to the pressure plate 402, compressing the fallen leaves into blocks, thereby compressing the fallen leaves on the road into biomass fuel and realizing the secondary utilization of the fallen leaves. A humidifier is also installed above the inside of the compression mechanism 4. The humidifier can be mounted on a crossbeam or rectangular frame. A sensor for detecting moisture content is also installed inside the compression mechanism 4. When the measured moisture content is less than 5%, the humidifier will automatically turn on to humidify the fallen leaves.

[0035] An outlet is provided on the housing 1 at the location of the baffle. The baffle includes a first baffle 411 and a second baffle 412 hinged to the rectangular frame. A first pulley 407 is provided on the first baffle 411, and a drive rod 410 is provided on the second baffle 412. A second pulley 409 is fixedly provided at the end of the drive rod 410 away from the second baffle 412. A second belt 408 connects the first pulley 407 and the second pulley 409. A transmission device 413 is also connected to the end of the drive rod 410 near the second baffle 412, and a roller is provided at the end of the transmission device 413 away from the drive rod 410. Understandably, the second baffle 412 and the transmission device 413 are hinged to the drive rod 410. When the first pulley 407 rotates, it drives the first baffle 411 to flip upwards. At the same time, it drives the second pulley 409 and the drive rod 410 to rotate, thereby driving the second baffle 412 to flip downwards. This also drives the end of the transmission device 413 near the second baffle 412 to move downwards. Finally, the transmission device 413 and the second baffle 412 are in a horizontal state. At this time, the push plate 403 pushes the compressed leaves out of the rectangular frame to the transmission device 413, which then delivers them out of the housing 1. Optionally, the first pulley 407 can be connected to a motor or other driving device to drive the first pulley 407; the transmission device 413 can be implemented using existing equipment, which will not be described in detail here.

[0036] Example 2: This embodiment provides a vehicle-mounted leaf handling method, which uses the vehicle-mounted leaf handling device as described in Embodiment 1. The method includes collecting the fallen leaves together using the collection mechanism 2, sending the collected leaves to the crushing mechanism 3 for crushing, and then sending the crushed leaves into the compression mechanism 4 for compression. During collection, the working angles of the roller brush device 204 and the two disc brushes 208 are adjusted by the angle adjustment device according to the area of ​​the working area and the slope of the ground. The working width of the two disc brushes is adjusted by rotating the disc brush bracket through the rotation drive device.

[0037] The above description is merely a preferred embodiment of this practice and is not intended to limit the scope of this practice. Various modifications and variations can be made to this practice by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this practice should be included within the protection scope of this practice.
