Abstract
Description
Technical Field
[0001] The invention relates to the technical field of gardening equipment, and in particular to a tree trunk whitewashing robot. Background Art
[0002] To ensure the sustainable and healthy development of trees, they need to be maintained regularly, and tree disease and pest control is one of them. The main method of prevention and control is to apply whitewash to the lower end of the trees. The material used for whitewashing trees is called whitewash, which is a kind of paint mixed with lime water and copper sulfate. Lime water has bactericidal and insecticidal effects. When applied to trees, it can kill fungi, bacteria and even some pests that parasitize on the roots and trunks of trees. Borers do not like white environments and generally like damp and dark places. Applying whitewash on the lower part of the tree can effectively prevent various insects from climbing up and causing damage to the trees.
[0003] The existing whitewashing machines usually spray whitewash directly on the lower limbs of trees. However, most trees are located in a relatively humid environment, which is prone to the production of parasites such as mosses and vines, as well as raised bark, or too much old bark at the lower end. This type of whitewashing has defects. When the whitewashing agent adheres to it, the bark will fall off and warp, and the surface layer of whitewashing agent is likely to fall off, resulting in a poor control effect. Summary of the invention
[0004] The purpose of the present invention is to provide a tree trunk whitewashing robot which can scrape and spray at the same time, and the whitewashing agent adheres to the surface of the cleaned tree trunk to prolong the prevention and control effect.
[0005] The embodiments of the present invention are realized through the following technical solutions: a tree trunk whitewashing robot, comprising an arc-shaped plug block, which is used to dock and insert into the tree trunk, and one end of the arc-shaped plug block is provided with a winding wheel; a grinding belt, one end of which is wound and connected with the winding wheel, and the other end is detachably connected with the arc-shaped plug block; a tightening ball assembly, which is arranged in the middle of the arc-shaped plug block, and the tightening ball assembly is aligned with the middle of the grinding belt; a nozzle, which is installed on the arc-shaped plug block, and the nozzle is arranged toward one side of the grinding belt; a lifting mechanism, which is connected to the tail end of the arc-shaped plug block, and is used to drive the grinding belt and the nozzle to move up and down; a vehicle body, the lifting mechanism is installed on the vehicle body, and the vehicle body drives the grinding belt and the arc-shaped plug block to rotate around the tree trunk.

DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.
[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0029] The following is further described in conjunction with specific embodiments. Figure 1-Figure 6 As shown, this embodiment is a tree trunk whitewashing robot, comprising an arc-shaped plug block 1, which is used for docking and plugging into the tree trunk, and one end of the arc-shaped plug block 1 is provided with a winding wheel 2; a grinding belt 3, one end of which is wound and connected with the winding wheel 2, and the other end is detachably connected with the arc-shaped plug block 1; a tightening ball assembly 4, which is arranged in the middle of the arc-shaped plug block 1, and the tightening ball assembly 4 is aligned with the middle of the grinding belt 3; a nozzle 5, which is installed on the arc-shaped plug block 1, and the nozzle 5 is arranged toward one side of the grinding belt 3; a lifting mechanism 6, which is connected to the tail end of the arc-shaped plug block 1, and is used to drive the grinding belt 3 and the nozzle 5 to move up and down; a vehicle body 7, and the lifting mechanism 6 is installed on the vehicle body 7, and the vehicle body 7 drives the grinding belt 3 and the arc-shaped plug block 1 to rotate around the tree trunk; specifically, when the device is in use, the vehicle body 7 is provided with an electric control power source, and the vehicle body 7 is controlled by the electric control power source to move The vehicle body 7 moves, which is a mature technology, so it is not repeated here. The vehicle body 7 moves to the tree trunk, cooperates with the arc-shaped plug block 1 to align with the tree trunk, and the tightening ball assembly 4 contacts the surface of the trunk. One end of the grinding belt 3 is pulled through and connected to the arc-shaped plug block 1. The trunk is located between the grinding belt 3 and the arc-shaped plug block 1. There is a difference in the diameter of the trunk. After being tightened by the winding wheel 2, the grinding belt 3 is in close contact with the surface of the trunk. The operator controls the vehicle body 7 to rotate around the trunk, and the lifting mechanism 6 gradually moves upward so that the grinding belt 3 and the nozzle 5 also slowly move upward synchronously. The grinding belt 3 spirally rises from the bottom of the trunk to fully grind off the old bark and moss on the trunk. The nozzle 5 is spaced more than 90° in the circumferential direction and the contact area between the grinding belt 3 and the trunk, so that the whitewashing agent sprayed from the nozzle 5 can just adhere to the scraped bark, realizing scraping and painting, and the whitewashing operation is efficient.
[0030] The nozzle 5 is located at almost the same level as the grinding belt 3, so the grinding belt 3 and the nozzle 5 can be applied very close to the part where the tree trunk contacts the ground.
[0031] It should be noted that the surface of the trunk is uneven and the trunk has a non-uniform circular structure. The point contact between the spherical body of the tightening ball assembly 4 and the surface of the trunk can be well fitted, and the spherical body of the tightening ball can roll in the circumferential and vertical directions of the trunk.
[0032] Reference Figure 5 As shown, the tightening ball assembly 4 in this embodiment includes a ball 41, a base 42 and a connecting rod 43, the ball 41 is embedded in the base 42 and is rollingly connected thereto, the connecting rod 43 is connected to the rear end of the base 42, and a limit plate 431 is provided on the connecting rod 43; a fixed plate 45, the rear end of the connecting rod 43 passes through the fixed plate 45, and a spring 44 is sleeved on the connecting rod 43, and the spring 44 abuts between the fixed plate 45 and the limit plate 431; specifically, because the grinding belt 3 and the ball 41 act on the opposite sides of the tree trunk respectively, and the diameter of the tree trunk is an irregular cylinder, the distance between the grinding belt 3 and the ball 41 will change continuously during the rotation of the grinding belt 3 and the arc-shaped plug 1. In order to avoid the phenomenon of excessive resistance or jamming when the grinding belt 3 and the ball 41 are too fixed during the grinding process, an elastic connection of the ball 41 is provided, and the ball 41 can adapt itself when rolling along the surface of the tree trunk.
[0033] Reference Figure 2 and Figure 3 As shown, the present embodiment further includes a liquid receiving tray 8, which is arranged below the nozzle 5 and close to the bottom end of the arc-shaped plug block 1; bristles 9 are arranged on the edge of the liquid receiving tray 8; specifically, if the spraying process is gradually sprayed upward from the bottom end of the trunk, the liquid receiving tray 8 can collect the fallen whitening agent, and the bristles 9 have good deformation and extrusion capabilities, and can change according to the shape of the contacted tree trunk surface, effectively preventing excess whitening agent from falling onto the ground, and the whitening agent in the liquid receiving tray 8 can flow onto the bristles 9, and when the entire arc-shaped plug block 1 rotates around the trunk, the bristles 9 can be evenly applied, and the whitening is more uniform.
[0034] Of course, this robot can also operate from top to bottom, depending on the actual working conditions.
[0035] Reference Figure 1 and Figure 4 As shown, the lifting mechanism 6 in this embodiment includes a connecting plate 61, a mounting frame plate, a screw rod 63, a guide rod 64 and a servo motor 65. The two ends of the screw rod 63 and the guide rod 64 are respectively connected to the mounting frame plate, and the servo motor 65 is arranged at the top of the mounting frame plate and connected to the screw rod 63; one end of the connecting plate 61 is connected to the arc plug block 1, and the screw rod 63 and the guide rod 64 respectively pass through the connecting plate 61 and are correspondingly connected thereto; specifically, the guide rod 64 is provided with two screw rods 63 that are triangular and parallel to each other, and the servo motor 65 drives the screw rod 63 to rotate, so that the connecting plate 61 drives the arc plug block 1 and the grinding belt 3 to move up and down along the trunk.
[0036] Furthermore, the vehicle body 7 is provided with a support block 11, and extension plates 621 are provided on both sides of the mounting frame plate. The support blocks 11 are respectively clamped on both sides of the mounting frame plate and slidably connected thereto, and a shock absorber 10 is provided between the support block 11 and the extension plate 621; specifically, there is a certain undulation on the ground surface around the tree trunk. In order to reduce the influence of the undulation of the vehicle body 7 with the undulation of the road surface on the lifting mechanism 6, a shock absorber 10 is set between the lifting mechanism 6 and the vehicle body 7 to reduce the influence, and a slot is provided in the middle of the support block 11 for the mounting frame plate to be clamped into to achieve sliding connection.
[0037] like Figure 6 As shown, the bark of the tree trunk is relatively hard, and a metal scraper 33 is provided on the inner side of the grinding belt 3, which is conducive to easier cleaning of the surface of the trunk, and the metal scrapers 33 are arranged in rows with uniform intervals, and a slag discharge port 32 is provided between two connected rows of metal scrapers 33 to prevent excessive scraping material from piling up between the grinding belt 3 and the tree trunk to form accumulation. When each layer of metal scraper 33 scrapes off waste materials such as moss, it can be removed from the slag discharge port 32 in time, and the waste materials are reduced from being too tightly attached to the tree trunk when falling, thereby reducing contact with the whitened area at the lower end. In order to further reduce this impact, a hair dryer can be provided for side blowing.
[0038] Reference Figure 2 As shown, a plug 31 is provided at one end of the grinding belt 3, and a socket 1A adapted to the plug 31 is provided at one end of the arc-shaped plug block 1; specifically, the plug 31 can be vertically moved out of the socket 1A on one side of the grinding belt 3, thereby separating the tree trunk from the arc-shaped plug block 1.
[0039] like Figure 2 and Figure 3 As shown, in order to enable the arc-shaped plug 1 to be more smoothly aligned with the ball 41 when the vehicle body 7 drives it to dock and clamp it into the tree trunk, the present embodiment also includes guide wheels 12, which are respectively installed on the inner side walls of the front end of the arc-shaped plug 1. In order to reduce the difficulty of aligning the arc-shaped plug with the tree trunk, when one of the guide wheels 12 contacts the tree trunk, the guide wheel 12 rolls along the surface of the tree trunk, which can better correct the arc-shaped plug 1 to deviate toward the tree trunk, so that the tree trunk is located in a more centered position of the arc-shaped plug 1. The spacing between the guide wheels 12 is usually larger than the diameter of the tree trunk, so when rotating, the guide wheel 12 does not contact the surface of the tree trunk.
[0040] Reference Figure 1 As shown, a material storage and mixing tank 13 and a material extraction pump 14 are also provided on the vehicle body 7 in this embodiment, and the material extraction pump 14 is respectively connected to the material storage and mixing tank 13 and the nozzle 5 through pipelines; specifically, whitening agent is stored in the material storage and mixing tank 13, and is output to the nozzle 5 through the control of the material extraction pump 14 to be evenly attached to the surface of the tree trunk.
[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
