Description

Technical Field

[0001] The invention relates to the technical field of tree brushing machines, and in particular to an embracing self-adaptive tree brushing machine capable of spiral lifting. Background Art

[0002] Whitewashing tree trunks can prevent insects, cold and beautify the environment. However, the current non-adaptive tree brushing machines cannot adapt to tree trunks with protrusions and forks due to the fixed nozzle diameter. On the other hand, the pressure of the sprayed liquid needs to be controlled to adapt to the tree diameter, which can easily cause the whitewashing liquid to splash. In addition, most adaptive tree brushing machines are large in size and cannot enter narrow areas such as roads and streets. When encountering steps of a certain height, the technical requirements are high. They are not widely popularized in society, and manual whitewashing is still widely promoted.

[0003] However, manual whitewashing has the following disadvantages: manual whitewashing uses brushes to apply the paint, which is inefficient and requires a lot of manpower. The height of the whitewashing needs to be controlled at about 1.2m, which requires a high level of proficiency among workers and is difficult to control. Workers may whitewash the same position of the tree multiple times, and the quality of the whitewashing varies. At the same time, the preparation of the whitewashing agent requires first dissolving quicklime with water, filtering out the residue, pouring in the dissolved salt, and finally adding lime sulfur, adhesives, etc. and stirring evenly. The whitewashing liquid should be used as soon as it is prepared, and should not be stored for too long. It needs to be prepared multiple times, which is harmful to the human body.

[0004] At present, most of the whitewashing machines on the market are non-adaptive whitewashing machines. According to the design idea of ​​the core module of the whitewashing machine - the spraying module. A non-adaptive machine with a low degree of automation. Its characteristic is that the number of nozzles contained in the spraying component is more than that of the existing hand-held spray whitewashing machine, and the spraying area per unit time, that is, the operating efficiency, is higher than that of the hand-held spray whitewashing machine. During operation, the operator holds the spraying component, puts the annular device with the nozzle on the tree, and then completes the spraying work along the direction of the trunk. However, the above patent has the following shortcomings: the diameter of the mechanical arm of the non-adaptive tree brushing machine is fixed, and the mechanical arm needs to be replaced or the pressure of the whitewashing liquid sprayed needs to be adjusted to adapt to trees of different diameters, which is easy to cause the whitewashing liquid to splash.

[0005] According to the prior art search, "Henan Science and Technology" 2020 No. 34, pp. 64-66 discloses a hand-pushed tree trunk whitewashing machine, Li Fan, Zhu Hongbo, Kang Zihui, which consists of a spraying cylinder (including a spraying device, a lifting device, an opening and closing mechanism) and a whitewashing agent storage tank, a delivery pump and related pipelines. The entire device is placed on a trolley. When the tree needs to be brushed, the worker uses his own trolley to move the device to the side of the tree, unfolds the spraying device cylinder, lets the cylinder hug the tree, and then uses the opening and closing handle to manually close the cylinder, start the delivery pump, and when ready, turn on the switch. The lifting device drives the nozzle up and down through a stepper motor to spray the whitewashing agent onto the surface of the trunk. However, the above patent has the following shortcomings: the adaptive tree brushing machine requires a shaft-mounted adaptive robotic arm with a height greater than or equal to the average whitewashing height of 1.2m to complete the spraying. The tree brushing machine has a high cost and a complex structure.

[0006] Through prior art search, it was found that the Chinese invention patent publication number is CN110355039A, which discloses a double-drum automatic tree brushing machine including: a body, a propulsion device, and a brushing device. The body includes handrails, a paint box, an air pressure pump, a chassis, a universal wheel, a motor, and an active bevel gear. The brushing device includes a roller, a roller holder, and a roller holder shaft. The two rollers are squeezed onto the tree trunk through the propulsion of the propulsion device to perform the brushing operation on the tree trunk. However, the above patent has the following shortcomings: brushing is performed by roller brush sponge, which increases the cost of use, and it is impossible to brush high tree trunks.

[0007] Therefore, developing a tree brushing device that is simple to operate and flexible in function has important practical significance for improving the labor intensity of garden workers. Summary of the invention

The gear box 32 is arranged through the roller brush frame 1, and the roller 33 is connected to one end of the gear box 32, and the other end of the gear box 32 is drivingly connected to the reduction motor 31. The roller brush barrel 2 and the driving system are respectively provided with a plurality of openings 13, and the plurality of roller brush barrels 2 and the plurality of driving systems are arranged at intervals, and the roller 33 and the roller brush barrel 2 are arranged corresponding to the tree trunk.

[0041] The water pump 4 is connected to a delivery pipe, which is arranged around the roller brush frame 1, and the other end of the rear axle 26 is connected to the delivery pipe. The water pump 4 is an anti-corrosion water pump 4, and a storage bottle 41 is connected to the water pump 4. The rear axle 26 of each roller brush barrel 2 is connected to a 6mm three-way connector 25 for connecting each roller brush barrel 2 and the water pump 4.

[0042] The gearbox 32 is arranged in a T-type gearbox 32 structure. The gearbox 32 includes a bevel gear and a roller. A transmission shaft 321 is connected to the bevel gear. A third sleeve is sleeved on the transmission shaft 321. A gear member is sleeved on the roller. The gear member and the bevel gear are meshed with each other. The roller 33 is arranged at both ends of the roller. In this embodiment, the gearbox 32 is arranged at 30° with the plane, and the roller 33 is a rubber wheel, which drives the rubber roller 33 with a fixed angle to move at an angle of about 30 degrees with the horizontal plane, so as to achieve spiral ascent and expand the contact area.

It is pressed against the inner hole wall of the stationary part by the elasticity after being pressed together to play a sealing role. The use of a skeleton oil seal can effectively seal. The function of the oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the external environment to prevent the lubricating oil from leaking. The skeleton is like the steel bars in the concrete component, which plays a reinforcing role and enables the oil seal to maintain its shape and tension. The oil film has the characteristics of fluid lubrication. Under the action of the surface tension of the liquid, the rigidity of the oil film just makes the oil film form a crescent surface at the contact end with the air, preventing the leakage of the working medium, thereby realizing the sealing of the rotating shaft. According to the structural form, it can be divided into a single-lip skeleton oil seal and a double-lip skeleton oil seal. Although the auxiliary lip of the double-lip skeleton oil seal plays a dust-proof role to prevent external dust and impurities from entering the machine, the double-lip rotation resistance is large, and general rotary seals are used for actively rotating shafts, while the roller brush barrel 2 is passively rotated with a low speed, a single lip can also ensure its sealing performance, so a double-headed single-lip skeleton oil seal is used.

[0045] Working principle: The water pump 4 is equipped with evenly stirred lime water, and multiple roller brush racks 1 are set on the tree trunk in an annular structure. Multiple roller brush racks 1 are connected head to tail and fixed. The reduction motor 31 is started, and the power is output to the gear box 32. The roller 33 rotates through the rotation of the roller in the gear box 32. The rotating roller 33 drives the roller brush rack 1 to spirally rise corresponding to the tree trunk. While the roller 33 rotates, the water pump 4 transports the lime water to the roller brush barrel 2 through the delivery pipe. The roller brush barrel 2 rolls and whitewashes the tree trunk through the movement of the roller 33. Manually judge whether the appropriate tree whitewashing height of about 1.2 meters is reached, click the button, use the electronic speed regulator and PWM wave signal generator to control the reduction motor 31, so that the roller 324 in the gear box 32 rotates in the opposite direction, and the tree brushing machine as a whole spirals down counterclockwise.
