Technical Field
[0001] This utility model relates to the technical field of grass cutting and shredding equipment, and in particular to a self-propelled integrated grass cutting and shredding equipment for slopes. Background Technology
[0002] There are many types of landscaping trimming equipment available both domestically and internationally. However, traditional lawnmowers have short, inflexible arms, making them unsuitable for trimming grass on slopes of high embankments. They also lack automatic height adjustment and the ability to shred weeds. This results in the felled leaves and weeds piling up or scattering on the road surface, affecting the appearance of the road and increasing the risk of fire.
[0003] The section of G25 Changshen Expressway from K1308+450 to K1362+229 has a maintenance mileage of 71.090 km. The slope of the expressway is about 10 meters long. Currently, weeding on the slope is usually done by using equipment to remove weeds within 4 meters of the upper part of the slope, and manual weeding is used to assist in the lower part of the slope. This is inefficient, poses a great safety hazard to personnel, and the weeds cannot be crushed, which can easily create a fire hazard.
[0004] Currently, there is a lack of integrated grass cutting and shredding equipment that can facilitate the removal of grass from slopes and the shredding of grass, and can quickly avoid encountering precast concrete blocks or small marker poles with arched slope frames through a lifting action.
[0005] Therefore, in order to address the above problems, a self-propelled slope grass cutting and shredding integrated device is proposed to solve these problems. Summary of the Invention
[0006] This invention addresses the shortcomings of existing technologies by developing a self-contained slope weed cutting and shredding integrated device. This invention enables the weed cutting saw blade to cover the entire slope working surface, making construction more convenient; it is height-adjustable, allowing for quick resumption of work after obstacle avoidance; and it adds the function of shredding weeds, shortening the time it takes for weeds to decompose.
[0007] The technical solution to the technical problem solved by this utility model is as follows: This utility model provides a self-propelled slope weeding and shredding integrated device, including: a chassis, which enables the device to move along the slope for convenient weeding, and is connected to a gantry frame; a lifting hydraulic rod, connected to the gantry frame, with the piston rod of the lifting hydraulic rod passing through the gantry frame and connected to an mounting plate, thereby driving a telescopic assembly to swing and move along the height direction, and quickly avoiding obstacles such as arched concrete precast blocks or small marker poles on the slope through a lifting action; an angle hydraulic rod, rotatably connected to the mounting plate, which is rotatably connected to a first mounting plate, which is rotatably connected to the mounting plate, thereby adjusting the angle of the weeding saw blade to make it parallel to the slope for convenient weeding; a telescopic assembly, with the first mounting plate connected to the telescopic assembly; a second mounting plate, connected to the telescopic assembly, which is connected to a frame, with the frame bearing connected to a rotating shaft; and a weeding saw blade connected to the rotating shaft.
[0008] As an optimization, the telescopic assembly includes symmetrical first guide rods and symmetrical second guide rods. A first mounting plate connects to the symmetrical first guide rods. The symmetrical first guide rods pass through a first fixed block and a first movable block, respectively. The symmetrical first fixed blocks are connected to their respective first guide rods. A second mounting plate connects to the symmetrical second guide rods. The symmetrical second guide rods pass through a second fixed block and a second movable block, respectively. The symmetrical second fixed blocks are connected to their respective second guide rods. Each first fixed block and each first movable block are rotatably connected to a corresponding first connecting rod. The center of each set of symmetrical first connecting rods is... The telescopic assembly is coaxially and cross-rotatably connected. Each second fixed block and each second movable block is rotatably connected to a corresponding second connecting rod. The centers of each set of symmetrical second connecting rods are coaxially and cross-rotatably connected. Each first connecting rod and each second connecting rod is rotatably connected to the round rod of the square frame connecting rod. The centers of two square frame connecting rods are coaxially and cross-rotatably connected. Through the symmetrical arrangement of the first and second guide rods, and their cooperation with the fixed blocks, movable blocks, connecting rods, and square frame connecting rods, stable telescopic movement of the telescopic assembly is achieved. The first mounting plate is rotatably connected to the telescopic hydraulic rod, and the piston rod of the telescopic hydraulic rod is rotatably connected to the round rod of the corresponding square frame connecting rod. The telescopic hydraulic rod provides power for the telescopic movement of the telescopic assembly, enabling weeding at different locations on the slope.
[0009] As an optimization, the rotating shaft is connected to the driving gear, the frame bearing is connected to the central shaft of the driven gear, the driving gear meshes with the driven gear, the central shaft of the driven gear is connected to the driving bevel gear, the frame is connected to symmetrical mounting rods, each mounting rod is connected to a crankshaft by a bearing, the crankshaft is connected to the driven bevel gear, the driven bevel gear meshes with the driving bevel gear, the frame is provided with a set of blade grooves, each blade groove is provided with a cutter, each cutter is connected to a straight groove, and the protruding round rod of the crankshaft is respectively set in the corresponding straight groove. By using gear meshing and bevel gear meshing transmission, the rotating shaft drives the grass saw blade and the cutter to move, realizing grass removal and shredding at the same time. As shown in the figure, the grass saw blade rotates counterclockwise, and after cutting the grass, the grass falling on the saw blade actively enters the frame following the movement of the grass saw blade, or the frame moves forward, causing the grass to passively enter the frame. The cutter reciprocates, cutting the grass and shredding it.
[0010] As an optimization, adjacent protruding circular rods of the crankshaft are distributed at 90° intervals in the circumferential direction. This ensures that every four cutters form a group, guaranteeing the regularity and stability of the cutter's movement, thereby improving the pulverizing effect.
[0011] As an optimization, the frame is connected to a motor via a motor bracket, and the output shaft of the motor is connected to the rotating shaft to provide power for the movement of related components.
[0012] As an optimization, the frame is connected to a protective cover to protect the motor and other components from dust. This prevents grass clippings, debris, and other contaminants from entering the equipment during operation, thus avoiding damage to the transmission system or affecting the normal operation of the equipment.
[0013] As an optimization, the frame is connected to a protective tube corresponding to the rotating shaft to protect the rotating shaft and prevent grass entering the frame from getting tangled on the rotating shaft.
[0014] As an optimization, the mounting plate is connected to symmetrical guide rods, which pass through the gantry frame. This provides vertical guidance for the mounting plate, allowing it to move smoothly up and down under the action of the lifting hydraulic rod, preventing swaying or deviation during the lifting process.
[0015] As an optimization, the chassis is connected to a counterweight to increase the stability of the equipment and prevent it from tipping over or sliding when operating on a slope due to an unstable center of gravity.

[0018] (2) This utility model uses an angled hydraulic rod to adjust the tilt angle of the equipment, so that it can better fit the slope of the slope and ensure that the grass saw blade can effectively contact the weeds, thereby improving the work efficiency. By raising and lowering the hydraulic rod, the equipment can achieve vertical height adjustment to adapt to different work requirements. At the same time, when encountering precast concrete blocks or small marker poles of the slope arch frame, the lifting action can achieve quick avoidance.
[0019] (3) By adopting a telescopic component, the grass saw blade of the equipment can be extended and adjusted according to the specific conditions of the slope, which further improves the adaptability and flexibility of the equipment. Attached Figure Description

This prevents grass clippings, debris, and other contaminants from entering the equipment during operation, thus avoiding damage to the transmission system or affecting the normal operation of the equipment.
[0031] The frame 15 is connected to the protective tube 23 corresponding to the rotating shaft 21 to protect the rotating shaft 21 and prevent grass entering the frame 15 from getting tangled on the rotating shaft 21.
[0032] The mounting plate 5 is connected to symmetrical guide rods 7, which pass through the gantry frame 3. This provides vertical guidance for the mounting plate 5, allowing it to move smoothly up and down under the action of the lifting hydraulic rod 6, preventing swaying or deviation during lifting.
[0033] The chassis 2 is connected to the counterweight 1 to increase the stability of the equipment and prevent it from tipping over or sliding when operating on the slope due to an unstable center of gravity.
[0034] The workflow of this embodiment is as follows:
[0035] Place the device along the slope, extend the angle hydraulic rod 4, which drives the telescopic assembly and the grass saw blade 22 to swing.

The device is then moved to move a certain distance along the length of the road. Then, when the extension and retraction are controlled, the hydraulic rod 11 retracts a certain distance, causing the grass saw blade 22 to move upwards again, moving a certain distance along the length of the road. This process is repeated to achieve the desired effect.
[0036] Example 2: This example further elaborates on Example 1.

The frame 15 is connected to symmetrical mounting rods 26, each of which is connected to a crankshaft 27 via a bearing. The crankshaft 27 is connected to a driven bevel gear 31, which meshes with the driving bevel gear 32. The frame 15 is provided with a set of blade grooves 24, each of which contains a cutter 25. Each cutter 25 is connected to a straight groove 28. The protruding round rods of the crankshaft 27 are respectively located in the corresponding straight grooves 28. By using gear meshing and bevel gear meshing transmission, the rotating shaft 21 drives the grass saw blade 22 and the cutter 25 to move, achieving grass removal and shredding simultaneously. Figure 3 As shown, the grass saw blade 22 rotates counterclockwise. After cutting the grass, the grass that falls onto the saw blade actively enters the frame 15 following the movement of the grass saw blade 22, or the frame 15 moves forward, causing the grass to passively enter the frame 15. The cutter 25 reciprocates, cutting the grass and achieving pulverization.
[0037] The adjacent protruding circular rods of the crankshaft 27 are distributed at 90° intervals in the circumferential direction. This ensures that every four cutters 25 form a group, guaranteeing the regularity and stability of the cutter 25's movement, thereby improving the crushing effect.
[0038] The workflow of this embodiment is as follows:
[0039] When the motor 20 rotates, the shaft 21 drives the drive gear 30 to rotate, the drive gear 30 drives the driven gear 29 and the drive bevel gear 31 to rotate, the drive bevel gear 31 drives the driven bevel gear 31 and the crankshaft 27 to rotate, the protruding round rod of the crankshaft 27 swings in the straight groove 28, driving the straight groove 28 to move, the straight groove 28 drives the cutter 25 to move along the blade groove 24, the grass saw blade 22 rotates counterclockwise, after cutting the grass, the grass that falls on the saw blade follows the movement of the grass saw blade 22 and actively enters the frame 15, or the frame 15 moves forward and the grass is passively entered into the frame 15, the cutter 25 reciprocates and cuts the grass, thus pulverizing it.
