Description

Technical Field

[0001] This utility model relates to the technical field of tree whitewashing, and in particular to a hand-push automated tree whitewashing machine. Background Technology

[0002] Tree whitewashing refers to the process of workers applying a layer of white liquid to the trunks of trees. This white liquid forms a protective layer that reflects 40-70% of sunlight, reducing heat absorption during the day and preventing bark cracking due to large temperature differences between day and night. It also has antibacterial and insect-repellent properties. While contributing to the aesthetic appeal of urban trees, it also protects trees from heat loss, pests, and diseases. Current tree whitewashing methods primarily rely on manual labor, which is labor-intensive, slow, and requires specialized whitewashing equipment due to variations in tree trunk size. Furthermore, the need to change spraying equipment for different types of trees often results in low efficiency.

[0003] Chinese Patent CN2020208401.0 discloses a tree whitening device for municipal public works, comprising a base, a paint tank, and a paint brush. The base has casters at its four corners. An L-shaped mounting bracket is fixedly connected to one side of the base's top. A motor is mounted on the top of the mounting bracket, with its output shaft rotatably connected to a lead screw. The lead screw is slidably connected to a lead screw slider. A telescopic rod is fixedly connected to the outer side of the lead screw slider. A U-shaped mounting seat is located in the middle of one side of the paint brush. The top of the telescopic rod is positioned within the groove of the mounting seat, and the telescopic rod and mounting seat are connected by fasteners. A paint tank is located on the top of the base near the mounting bracket. The paint tank's outlet is connected to one end of a conveying pipe, and the other end of the conveying pipe is connected to a flexible conveying hose via a union. This invention can quickly and automatically whiten trees, reducing manual labor and paint waste, resulting in high tree whitening efficiency. However, this invention can only spray paint on one side of the tree; whitening a complete circle is too inefficient, as it cannot directly spray around the trunk, leading to low whitening efficiency. Utility Model Content

[0004] The main purpose of this utility model is to overcome the defects of the above-mentioned background technology and provide a hand-push automated tree whitening machine. This utility model can meet the actual tree whitening needs. It achieves tree whitening by mounting a spraying component, a lifting mechanism and a material storage device on a frame. The lifting mechanism can change the tree whitening height according to actual needs. At the same time, the spraying component is connected to the lifting mechanism through the first connecting rod and the second connecting rod, which can adjust and change the surrounding spraying range of the spraying component. The nozzle support rod can be expanded or reduced according to the size of the tree to cope with various tree whitening scenarios and improve the versatility of the tree whitening machine.

[0005] To achieve the above objectives, this utility model proposes a hand-push automated tree whitening machine, comprising a spraying assembly, a lifting mechanism, a frame, and a material storage device. The lifting mechanism is located at one end of the frame, the spraying assembly is mounted on the lifting mechanism, and the material storage device is located at the other end of the frame, communicating with the spraying assembly. The spraying assembly includes a nozzle support rod, several nozzles, a conveying pipe, a first connecting rod, a second connecting rod, and a mounting plate. Two sets of nozzle support rods are symmetrically arranged, with one end of each set hinged to the mounting plate via the first and second connecting rods, respectively. The mounting plate is fixedly connected to the lifting mechanism. Several nozzles are spaced apart and mounted on the two sets of nozzle support rods, communicating with the material storage device via the conveying pipe. The first connecting rod has meshing gears at one end of the mounting plate, enabling the two sets of nozzle support rods to rotate synchronously to open or close. By loading and unloading the spraying assembly, lifting mechanism, frame, and storage device, the whitewash liquid is stirred and transported to the spraying assembly through the storage device. The lifting mechanism moves up and down to drive the spraying assembly to spray the trees in all directions. The nozzle support rod is hinged to the mounting plate on the lifting mechanism through the first connecting rod and the second connecting rod. The expansion and contraction of the nozzle support rod can be controlled by moving the first connecting rod and the second connecting rod, changing the nozzle support rod and its mounted nozzle and delivery pipe. This can meet various tree whitewashing needs and improve the versatility of the tree whitewashing machine.

[0006] Furthermore, a servo motor is connected to the gear axle. By controlling the rotation of the gear via the servo motor, the first connecting rod is controlled to expand outward or retract inward, thereby achieving intelligent control of the nozzle support rod's expansion and contraction.

[0007] Furthermore, the lifting mechanism includes a lifting bracket, a lifting guide rail, a lifting plate, a lifting power source, and a transmission assembly. The lifting bracket is fixed to the frame, the lifting guide rail is fixed to the side of the lifting bracket, the transmission assembly is disposed between the lifting guide rails, the lifting plate is slidably disposed on the lifting guide rails, the lifting plate is connected to the transmission assembly, the output end of the lifting power source is connected to one end of the transmission assembly, and the mounting plate is mounted on the lifting plate.

[0008] By assembling the lifting bracket, lifting guide rail, lifting plate, lifting power source, and transmission components, the lifting power source and transmission components work together to enable the lifting plate to move up and down on the lifting guide rail, providing driving force for the up and down movement of the spraying components, thus enabling the trees to be whitened by moving up and down.

[0009] Furthermore, the transmission assembly includes a fixed plate, a bearing seat, a lead screw, a driven gear, and a lead screw nut assembly. The fixed plate is laterally fixed to the lower end of the lifting bracket. The bearing seat is fixed to both the fixed plate and the lifting bracket. The lead screw is rotatably connected to the bearing seat. The driven gear is fixed to one end of the lead screw. The lead screw is meshed with the drive gear on the output end of the lifting power source through the driven gear. The lead screw nut assembly is sleeved on the lead screw and fixed to the lifting plate.

[0010] A bearing seat is set on the fixed plate, and the two ends of the lead screw are rotatably connected to the bearing seat. At the same time, a lead screw nut pair is sleeved on the lead screw. The lead screw is driven to rotate by the meshing of the driven gear and the rotating drive gear. This allows the lead screw nut pair to move up and down on the lead screw, providing driving force and a moving basis for the spraying assembly to move up and down in the lifting mechanism.

[0011] Furthermore, the material storage device includes a mixing tank, a stirring device, and a pump. The mixing tank is mounted on the frame via a base, the stirring device is mounted on the base, the inlet of the pump is connected to the mixing tank, and the outlet of the pump is connected to the delivery pipe. By placing the stirring device on the mixing tank and stirring it within the tank, the lime and water added to the mixing tank are stirred into a whitewash solution. This allows for real-time stirring and production of the whitewash solution based on actual needs, which is then transported out via the pump.

[0012] Furthermore, the stirring device includes a stirring power source and stirring blades. The stirring power source is fixed to the bottom end of the stirring tank, and the output shaft of the stirring power source extends into the stirring tank. The stirring blades are mounted on the output shaft of the stirring power source located inside the stirring tank. By driving the stirring blades to rotate inside the stirring tank, the stirring power source can produce whitening liquid in real time according to actual needs.

[0013] Furthermore, the frame includes a mobile platform, casters, and a pusher. The mobile platform is arranged horizontally, the casters are fixed to both sides of the mobile platform, and the pusher is located on one side of the mobile platform. A spraying assembly, a lifting mechanism, and a material storage device are mounted on the mobile platform. The pusher drives the casters on the bottom of the mobile platform to roll, moving the mobile platform and its mounted equipment, thus improving equipment mobility while avoiding manual handling.

[0014] Furthermore, the hand-push automated tree whitening machine also includes a drive power cabinet, which is electrically connected to the mixing power source, the material pump, and the lifting power source. The driving power cabinet enables intelligent control of the mixing power source and the lifting power source.

[0015] The beneficial effects of this utility model include: it can meet the actual needs of tree whitening, and can achieve tree whitening by mounting a spraying component, a lifting mechanism and a material storage device on a frame. The lifting mechanism can change the tree whitening height according to actual needs. At the same time, the spraying component is connected to the lifting mechanism through the first connecting rod and the second connecting rod, which can adjust and change the surrounding spraying range of the spraying component. The nozzle support rod can be expanded or reduced according to the size of the tree trunk, which can cope with a variety of tree whitening scenarios and improve the versatility of the tree whitening machine.

[0027] Please see Figure 1 Figure 2 Figure 6 The manual-push automated tree whitening machine disclosed in the embodiment includes a spraying assembly 1, a lifting mechanism 2, a frame 3, and a material storage device 5. The lifting mechanism 2 is located at one end of the frame 3, the spraying assembly 1 is mounted on the lifting mechanism 2, and the material storage device 5 is located at the other end of the frame 3 and is connected to the spraying assembly 1. The spraying assembly 1 includes a nozzle support rod 11, a plurality of nozzles 12, a conveying pipe 13, a first connecting rod 15, a second connecting rod 16, and a mounting plate 26. Two sets of nozzle support rods 11 are symmetrically arranged, and one end of each set of nozzle support rods 11 is connected to the first connecting rod 15 and the second connecting rod 16, respectively. The connecting rod 16 is hinged to the mounting plate 26, the mounting plate 6 is fixedly connected to the lifting mechanism 2, and a number of nozzles 12 are spaced apart on two sets of nozzle support rods 11. The number of nozzles 12 are connected to the material storage device 5 through the conveying pipe 13. The first connecting rod 15 is provided with meshing gears at one end of the mounting plate 26, so that the two sets of nozzle support rods 11 can rotate synchronously to open or close. The hand-push automatic tree whitening machine also includes a drive power cabinet 4, which is electrically connected to the mixing power source 53, the material pump 51 and the lifting power source 24. A servo motor 17 is connected to the gear axle.

[0028] The spraying assembly 1, lifting mechanism 2, and material storage device 5 are fixed on the frame 3. The material storage device 5 stirs the whitewash liquid and delivers it to the spraying assembly 1. Simultaneously, the lifting mechanism 2 moves the spraying assembly 1 up and down, enabling all-around spraying of the trees to meet the whitewashing requirements. The spraying assembly 1 consists of a nozzle support rod 11, nozzles 12, a conveying pipe 13, a first connecting rod 15, a second connecting rod 16, and a mounting plate 26. Multiple nozzles 12 are installed on the nozzle support rod 11, and the nozzles 12 are connected to the material storage device 5 through the conveying pipe 13, thus connecting the spraying assembly 1 and the material storage device 5 into one unit, completing the basic foundation of the tree whitewashing spraying equipment. The mounting plate 26 connects the nozzle support rod 11, nozzles 12, conveying pipe 13, first connecting rod 15, second connecting rod 16, and mounting plate 26. The connecting rod 15 and the second connecting rod are connected to the lifting mechanism 2 to build the equipment foundation for the spraying component 1 to move up and down for spraying. At the same time, the nozzle support rod 11 is connected to the mounting plate 26 through the first connecting rod 15 and the second connecting rod 16. The angle of the nozzle support rod 11 can be expanded or reduced by changing the hinge angle between the first connecting rod 15 and the lifting mechanism 2 through the servo motor 17. This can adjust and change the surrounding spraying range of the spraying component. The nozzle support rod can be expanded or contracted according to the size of the tree trunk to cope with various tree whitening scenarios, thereby improving the versatility of the hand-push automated tree whitening machine. The intelligent control of the hand-push automated tree whitening machine is achieved through the electrical connection of the drive power cabinet 4, the mixing power source 53, the material pump 51, and the lifting power source 24, thereby improving the work efficiency.

[0029] Please see Figure 3 In a specific example, the lifting mechanism 2 includes a lifting bracket 21, a lifting guide rail 22, a lifting plate 23, a lifting power source 24, and a transmission component 25. The lifting bracket 21 is fixed on the frame 3, the lifting guide rail 22 is fixed on the side of the lifting bracket 21, the transmission component 25 is disposed between the lifting guide rails 22, the lifting plate 23 is slidably disposed on the lifting guide rail 22, the lifting plate 23 is connected to the transmission component 25, the output end of the lifting power source 24 is connected to one end of the transmission component 25, and the mounting plate 26 is mounted on the lifting plate 23.

[0030] Two lifting guide rails 22 are provided on the side of the lifting bracket 21, and a lifting power source 24 is provided at the top of the lifting bracket 21. The lifting plate 23 is slidably mounted on the lifting guide rails 22, and the lifting plate 23 is connected to the transmission component 25. At the same time, one end of the transmission component 25 is connected to the output shaft of the lifting power source 24, so that the lifting power source 24 drives the transmission component 25 to rotate, thereby driving the lifting plate 23 to move up and down on the lifting guide rails 22. The mounting plate 26 is mounted on the lifting plate 23, and one end of the mounting plate 26 is connected to the first connecting rod 15 and the second connecting rod 16. So that when the lifting power source 24 drives the transmission component 25 to rotate and drives the lifting plate 23 to move up and down, it can also drive the mounting plate 26 to move up and down, thereby driving the spraying component 1 connected to the mounting plate 26 to move up and down, so as to spray the trees in both vertical and horizontal positions. This can meet the spraying needs of various trees and improve work efficiency.

[0031] Preferably, the transmission assembly 25 includes a fixed plate 251, a shaft seat 252, a lead screw 253, a driven gear 254, and a lead screw nut assembly 255. The fixed plate 251 is laterally fixed to the lower end of the lifting bracket 21. The shaft seat 252 is fixed to both the fixed plate 251 and the lifting bracket 21. The lead screw 253 is rotatably connected to the shaft seat 252. The driven gear 254 is fixed to one end of the lead screw 253. The lead screw 253 is meshed with the drive gear 256 on the output end of the lifting power source 24 through the driven gear 254. The lead screw nut assembly 255 is sleeved on the lead screw 253 and fixed to the lifting plate 23. The fixed plate 251 and the lifting bracket are fixed to the lower end of the lifting bracket 21. A bearing seat 252 is provided on the upper end of the 21. The lead screw 253 is rotatably connected to the bearing seats 252 at both ends. One end of the lead screw 252 is provided with a driven gear 254 that meshes with the drive gear 256. By rotating the drive gear 256 and the driven gear 254 that meshes with it, the lead screw 253 rotates synchronously between the bearing seats 252. This allows the lead screw nut pair 255 sleeved on the lead screw 253 to move up and down based on the rotation direction of the lead screw 253. This enables the lifting plate 23 connected to the lead screw nut pair 255 to move up and down, providing the conditions for the movement of the spraying assembly 1. At the same time, by setting the lead screw 253 to roll on the bearing seat 252, friction is reduced while the transmission efficiency is high.

[0032] Please see Figure 4In the specific example, the material storage device 5 disclosed includes a mixing tank 54, a mixing device 50, and a pump 51. The mixing tank 54 is mounted on the frame 3 via a base 52. The mixing device 50 is located on the base 52. The inlet end of the pump 51 is connected to the mixing tank 54, and the outlet end of the pump 51 is connected to the conveying pipe 13. The mixing device 50 includes a mixing power source 53 and a mixing blade 55. The mixing power source 53 is fixed to the bottom end of the mixing tank 54. The output shaft of the mixing power source 53 passes through the mixing tank 54, and the mixing blade 55 is mounted on the output shaft of the mixing power source 53 located inside the mixing tank 54.

[0033] The output shaft of the stirring power source 53, fixed on the base 52, passes through the stirring tank 54, and the output end of the stirring power source 53 is connected to the stirring blade 55. The stirring blade 55 rotates in the stirring tank 54, which can stir the lime powder and water poured into the stirring tank 54 into whitewash liquid. This allows for real-time stirring and production of whitewash liquid based on actual whitewashing needs, which can cope with various situations and improve the adaptability of the hand-push tree whitewashing machine. At the same time, the automatic stirring of lime and water improves the stirring efficiency while avoiding the harm to the stirrer caused by manual stirring, thus improving work safety. The inlet end of the pump 51 extends into the stirring tank 54 to draw out the whitewash liquid in the stirring tank and push it onto the nozzle 12 through the conveying pipe 13, realizing the transportation of whitewash liquid and the spraying of whitewash liquid at the same time. By adjusting the working frequency of the pump 51, the transportation and spraying rate of whitewash liquid can be changed, thereby improving the spraying efficiency.

[0034] Please see Figure 5 In a specific example, the frame 3 includes a mobile platform 31, mobile wheels 32, and a mobile pusher 33. The mobile platform 31 is arranged horizontally, the mobile wheels 33 are fixed on both sides of the mobile platform 31, and the mobile pusher 33 is located on one side of the mobile platform 31. The mobile wheels 32 are arranged on the bottom side of the mobile platform 31, and the mobile pusher 33 pushes the mobile platform 31 and its mounted spraying components 1, lifting mechanism 2, and material storage device 5 to move, thereby avoiding manual handling and improving the mobility of the equipment.
