[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] The following are detailed descriptions, which are not limitations of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0024] A vegetation spraying device for mine restoration includes a vehicle body 1, a liquid storage tank 2 fixedly connected to the top of the vehicle body 1, a spray pipe 3 rotatably connected to the top of the liquid storage tank 2, a liquid pump 4 fixedly connected to one side of the liquid storage tank 2, an inlet end of the liquid pump 4 connected to the liquid storage tank 2 through a liquid inlet pipe, and an outlet end of the liquid pump 4 connected to the spray pipe 3 through a liquid outlet hose; The cleaning assembly also includes a cleaning component, which includes a connecting frame 101 movably connected to the outside of the liquid storage tank 2, a brush plate 102 movably set on the connecting frame 101, a collection frame 103 fixedly connected to the bottom of the vehicle body 1, a disc 104 rotatably set on the side of the liquid storage tank 2, a motor 108 set on the side of the liquid storage tank 2 and with the rotor end coaxially fixedly connected to the disc 104, a connecting post 105 set on the disc 104, a bar frame 106 sleeved on the connecting post 105, and a connecting rod 107 fixedly connected between the bar frame 106 and the connecting frame 101. Two sets of guide rods 9 are symmetrically fixedly connected to the outside of both sides of the liquid storage tank 2, and the guide rods 9 are slidably connected to the connecting frame 101. The connecting post 105 is fixedly connected between the two sets of discs 104 on the same side and close to the edge.

[0025] The primary technical effect of this embodiment lies in its ability to simultaneously clean the road surface during travel, ensuring smooth movement and improving spraying efficiency. The technical solution of this embodiment is that the device employs a vehicle body 1 as its main body, designed for movement over mining terrain. Upon activation, a motor 108, located on the side of the liquid storage tank 2, directly drives the disc 104 to rotate. A connecting post 105 is eccentrically fixed to the rotating disc 104, similar to the pin of a cam or crank. A bar frame 106 is sleeved onto the connecting post 105. As the disc 104 rotates, the connecting post 105 performs circular motion, driving the sleeved bar frame 106 in reciprocating linear motion. A connecting rod 107 is fixed to the bar frame 106 at one end and fixedly connected to the connecting frame 101 at the other end. Therefore, the reciprocating linear motion of the bar frame 106 is transmitted through the connecting rod 107, driving the connecting frame 101 in reciprocating linear motion. The brush plate 102 is movably arranged on the connecting frame 101. The swing of the connecting frame 101 drives the brush plate 102 to swing back and forth in front of the vehicle body 1. The process of the brush plate 102 sweeping forward can sweep away impurities such as gravel and sand on the road surface. The collection frame 103 fixedly connected to the bottom of the vehicle body 1 is located behind the brush plate 102. The impurities swept backward by the brush plate 102 will be pushed or gathered into the collection frame 103 to prevent the impurities from spreading or hindering the movement again. While the cleaning component is working, the vehicle body 1 can move forward normally. The liquid pump 4 works continuously to pump the liquid in the liquid storage tank 2, such as vegetation nutrient solution, into the spray pipe 3 through the liquid inlet pipe and the liquid outlet hose, and the spray pipe 3 is sprayed onto the mine slope for vegetation restoration. The rotating connection of the spray pipe 3 allows the spraying angle to be adjusted.

[0026] The benefit of this embodiment is that, through the automatically swinging brush plate 102, it is possible to effectively clean up impurities such as gravel and sand on the vehicle's forward path, prevent these impurities from blocking the wheels or chassis, and ensure that the spraying device can move forward smoothly and continuously, thereby improving the operating efficiency and continuity of the entire spraying process. Gravel, sand and other impurities are cleaned away, reducing the risk of these hard objects causing jamming, wear or damage to the wheels, chassis structure, drive system, etc., and improving the durability and reliability of the equipment. The collection frame 103 is provided to recycle some of the impurities swept into the range of the vehicle body 1, and the front and back cleaning method can prevent them from splashing around or scattering over a wider area during the cleaning process, avoiding causing new obstacles or contaminating the already cleaned area.

[0027] A baffle 201 is slidably connected to the collecting frame 103 , and a guide slot is provided on the vehicle body 1 at a position corresponding to the baffle 201 . Two sets of connecting rods 202 are symmetrically hinged between the connecting frame 101 and the baffle 201 .

[0028] The baffle 201 is not a fixed structure, but rather a linkage mechanism linked to the connecting frame 101. This allows for automatic opening and closing, without the need for an additional power source or manual operation, to control the opening and closing state of the collection frame 103 entrance. As the brush plate 102 sweeps impurities and approaches the collection frame 103, the baffle 201 automatically rises, driven by the linkage 202, and switches to an open state, providing a smooth entrance for the swept impurities, facilitating their smooth entry into the collection frame 103. Even if some gravel or sand in the collection frame 103 falls back onto the road surface due to vehicle shaking, it can be swept back into the collection frame 103 by the approaching brush plate 102. When the brush plate 102 completes its cleaning action and returns to its original position away from the collection frame 103, the baffle 201 automatically descends, driven by the linkage mechanism, and switches to a closed state, preventing the bumpy vehicle from causing gravel or sand in the collection frame 103 to fall back onto the road surface, causing secondary pollution or becoming an obstacle again.

[0029] The top of the brush plate 102 is symmetrically fixed with two sets of vertical rods 1001, and the vertical rods 1001 are slidably connected to the connecting frame 101. The top of the vertical rods 1001 is fixedly connected to the limit plate, and the outer part of the vertical rods 1001 is provided with a spring 1002. The two ends of the spring 1002 are fixedly connected to the limit plate and the connecting frame 101 respectively.

[0030] Among them, the downward pressure exerted by the spring 1002 on the brush plate 102 is relatively constant and is also adjustable through the selection of the spring stiffness. This ensures that under normal working conditions without encountering major obstacles, the brush maintains a stable pressing force with the ground, and will not be completely lifted up and lose its function due to slight bumps, nor will it lose its cleaning power due to insufficient gravity, thereby providing a continuous and uniform cleaning effect. In addition, the road surface in the mine repair area is highly uneven and may have ups and downs, potholes or large protrusions. At this time, the vertical rod 1001 will overcome part of the elastic force of the spring 1002 and slide upward, allowing the brush plate 102 to be lifted, avoiding violent hard collisions with obstacles, and effectively protecting the brush plate 102 from impact damage.

[0031] Spray nozzles are evenly spaced outside the spray pipes 3. A rotating shaft 5 is rotatably connected to the top of the liquid storage tank 2. Geared discs 6 are coaxially fixedly connected to each end of the rotating shaft 5. Racks 7 are meshed with the geared discs 6 and fixedly connected to the connecting frame 101. Bevel gears 8 are fixedly mounted on the exteriors of both sides of the rotating shaft 5 and on the exteriors of one end of the two sets of spray pipes 3. The two sets of bevel gears 8 on the same side are meshed and connected.

[0032] Among them, the arrangement of the rotating shaft 5, the gear disc 6, the rack 7, and the bevel gear 8 cleverly converts the horizontal reciprocating motion of the connecting frame 101 into the rotational motion of the rotating shaft 5 through the meshing of the rack 7 and the gear disc 6. The rotation of the rotating shaft 5 is then meshed by the bevel gears 8 on both sides, changing the power and the direction of motion by 90°, and finally driving the spray pipe 3 to swing back and forth. By utilizing the power of the cleaning action itself, the spray angle is automatically, synchronously, and dynamically adjusted. The back-and-forth rotation of the spray pipe 3 enables the sprayed liquid to cover a wider lateral range. This dynamic swinging spraying avoids local oversaturation or spraying blind spots caused by fixed-angle spraying, especially in the direction of travel. The swinging spraying can better fill the gaps between adjacent spraying bands, especially for uneven mine slopes. The swinging spraying can better reach surfaces at different angles, significantly improving the effect and success rate of vegetation restoration.

[0033] The interior of the liquid storage tank 2 is rotatably connected to an agitator 10 , and both ends of the agitator 10 are coaxially fixedly connected to the two side discs 104 .

[0034] Disc 104 is already driven to rotate by motor 108. By directly and coaxially connecting the two ends of agitator 10 to discs 104 on either side, the aforementioned design fully reuses the power of motor 108, eliminating the need for a separate drive motor, reduction mechanism, and control system for the agitator. This significantly simplifies the structure, reducing the equipment's manufacturing cost, weight, energy consumption, and potential failure points. Liquids used for vegetation spraying in mines, such as nutrient solutions, seed-containing slurries, and clay suspensions, are often prone to sedimentation, stratification, or flocculation. If the liquid in the tank is left to stand, solid particles such as fertilizer, seeds, and fillers will settle to the bottom of the tank. Agitator 10 rotates continuously and compulsorily with disc 104, vigorously stirring the liquid in tank 2. This effectively prevents sedimentation, stratification, and agglomeration of liquid components, ensuring that the liquid always maintains a uniformly mixed state and avoiding uneven concentration of the sprayed liquid or pipe clogging due to sedimentation. Moreover, the spray liquid with uniform composition after stirring is the basis for ensuring the spraying effect. Stirring ensures that the liquid delivered by each pump has basically the same concentration of active ingredients.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] The specific embodiments are merely for explaining the present invention. It should be noted that the serial numbers of the following embodiments are not intended to limit the preferred order of the embodiments.

The inlet end of the liquid pump 4 is connected to the liquid storage tank 2 through a liquid inlet pipe, and the outlet end of the liquid pump 4 is connected to the spray pipe 3 on the same side through a liquid outlet hose. Nozzles are equidistantly arranged on the outside of the spray pipe 3, which can increase the spraying range. A liquid injection pipe is fixedly connected to one side of the top of the liquid storage tank 2 to facilitate the injection of spray liquid into the liquid storage tank 2.

[0038] The impurity cleaning component for cleaning ground impurities includes a connecting frame 101 movably connected to the outside of the liquid storage tank 2, a brush plate 102 movably provided on the connecting frame 101, a collecting frame 103 fixedly connected to the bottom side of the vehicle body 1, two groups of discs 104 are provided on both sides of the liquid storage tank 2, a connecting column 105 is provided between the two groups of discs 104 on the same side, a bar frame 106 is movably provided on the outside of the connecting column 105, a connecting rod 107 is fixedly connected between the bar frame 106 and the connecting frame 101, the top of the liquid storage tank 2 is rotatably connected to the rotating shaft 5, both ends of the rotating shaft 5 are coaxially fixedly connected to the toothed disc 6, the toothed disc 6 is meshed with a rack 7 and the rack 7 is fixedly connected to the connecting frame 101, and the two ends of the rotating shaft 5 are fixedly connected. The outside of the side and one end of the two groups of spray pipes 3 are fixedly sleeved with a bevel gear 8, and the two groups of bevel gears 8 on the same side are meshed and connected. The outside of both sides of the liquid storage tank 2 are symmetrically fixed with two groups of guide rods 9, and the guide rods 9 are slidably connected to the connecting frame 101, which can play a certain guiding role in the horizontal movement of the connecting frame 101. The connecting column 105 is fixedly connected between the two groups of discs 104 on the same side near the edge. The inside of the liquid storage tank 2 is rotatably connected to the agitator 10 and the two ends of the agitator 10 are respectively coaxially fixedly connected to the discs 104 on both sides. The outside of one side of the liquid storage tank 2 is fixedly connected to a motor and the rotor end of the motor is coaxially fixedly connected to the disc 104 on one side, which is convenient for stirring the spray liquid inside the liquid storage tank 2.

[0039] A baffle 201 is slidably connected to the collecting frame 103 , and a guide slot is provided on the vehicle body 1 at a position corresponding to the baffle 201 . Two sets of connecting rods 202 are symmetrically hinged between the connecting frame 101 and the baffle 201 .

[0040] The implementation principle of a vegetation spraying device for mine restoration in the embodiment of the present application is as follows: spraying liquid is added to the liquid storage tank 2 through the liquid injection pipe, and then the device is moved to the designated area, and then the liquid pump 4 is started. The liquid pump 4 can transport the spraying liquid inside the liquid storage tank 2 to the spray pipe 3 and spray it out through the nozzle to spray and irrigate the mine vegetation, and then the motor is started, and the motor drives the discs 104 on both sides to rotate at the same time, and under the movable connection between the bar frame 106 and the connecting column 105 and the sliding cooperation between the connecting frame 101 and the guide rod 9, the connecting frame 101 can be driven to move back and forth horizontally, thereby driving the brush plate 102 to move back and forth to sweep impurities on the ground into the collection frame 103, thereby achieving the purpose of cleaning impurities, effectively avoiding the problem that the existing device is difficult to remove impurities on the ground, which will affect the spraying irrigation effect of vegetation, and the rotation of the disc 104 will also drive the agitator 10 to rotate, so that the spraying liquid inside the liquid storage tank 2 can be The two sets of spray pipes 3 are driven to rotate back and forth by the meshing connection between the rack 7 and the toothed disc 6 and the meshing connection between the two sets of bevel gears 8 on the same side, so as to achieve the purpose of adjusting the spray angle back and forth, thereby ensuring the thoroughness of spraying the mine vegetation. In the process of the connecting frame 101 moving back and forth, the hinged action between the connecting frame 101, the baffle 201 and the connecting rod 202 are coordinated, and the sliding action between the baffle 201 and the collection frame 103 and the guide groove is coordinated. When the brush plate 102 approaches the collection frame 103, the baffle 201 will automatically rise to open the collection frame 103 to collect impurities. When the brush plate 102 moves away from the collection frame 103, the baffle 201 will automatically fall to close the collection frame 103 to prevent impurities from falling from the collection frame 103. Finally, the driving device moves until the spraying of the mine vegetation is completed.

By utilizing the sliding fit between the vertical rods 1001 and the connecting frame 101 and the elastic effect of the spring 1002 itself, the bristles on the brush plate 102 can always keep in contact with the ground, thereby improving the cleaning effect of impurities.
