[0002] During the growth of trees, trees may develop a variety of diseases, among which tree rot is one of them. In order to treat tree rot, planters generally remove the rot lesions. The existing method mainly uses a manual scraper or an angle grinder to scrape the bark of the tree, thereby treating the tree rot.

[0003] Scrapers and angle grinders can scrape the bark from the trunk of a tree very well, but it is not easy to scrape the bark from the horns (the part at the base of the branches after the branches fork during the growth process of the tree). The space at the horns of trees is small, and the scraping workload of scrapers is large and the efficiency is low. The blades and heads of angle grinders are large, so it is not easy to reach the horns of trees, nor is it easy to scrape the bark from the horns of trees cleanly.

[0004] Therefore, there is an urgent need in the market for a bark scraper that can quickly and conveniently scrape off the bark at the corners of trees to achieve bark scraping at the corners of trees. Based on this, the present application proposes a bark scraping tool, a bark scraping extension component, and a bark scraping machine for the corners of trees. Summary of the invention

[0030] The embodiment of the first aspect of the present application provides a skin scraping tool 100, such as Figure 1 and Figure 2 As shown, it includes a base plate 110 and a cutter head 120. The base plate 110 is provided with a mounting hole 111. The base plate 110 can be mounted on a transmission component through the mounting hole 111, so that the transmission component drives the entire skin scraping tool 100 to rotate.

[0031] like Figure 1 and Figure 2 As shown, the cutter head 120 is disposed on the substrate 110, and the blade 121 of the cutter head 120 exceeds the surface of the substrate 110, so that the blade 121 can contact the bark, thereby scraping the bark during rotation to achieve tree bark scraping.

[0032] Generally, there are multiple blade heads 120 on the substrate 110 to improve the scraping efficiency.

[0033] When in use, the base plate 110 is mounted on the transmission component through the mounting hole 111 so that it can rotate with the transmission component. The blade 121 of the cutter head 120 exceeds the surface of the base plate 110, and the blade 121 can contact the bark. As the cutter head 120 rotates, the bark can be scraped.

[0034] Compared with the prior art, the blade 121 of the blade head 120 of the scraping tool 100 can contact the bark, thereby achieving scraping and controlling tree rot diseases.

[0035] In some embodiments, Figure 2 As shown, the cutter head 120 is provided with blades 121 on both sides of the substrate 110 in the thickness direction and on the side away from the mounting hole 111. In this way, the cutter head 120 can scrape the skin on both sides of the substrate 110 in the thickness direction and on the outer side of the substrate 110, and the skin scraping tool 100 has three cutting working surfaces, which improves the applicable working conditions and application range of the skin scraping tool 100.

[0036] In some embodiments, Figure 1 As shown, the substrate 110 may be a circular plate, on which a plurality of cutting heads 120 are arranged, and the cutting heads 120 may be evenly distributed relative to the center of the circle.

[0037] In other embodiments, Figure 2 As shown, the substrate 110 is a regular polygonal plate (such as a regular pentagon and a regular hexagon, etc.), a knife groove 130 is provided at the vertex of the regular polygonal plate, and a knife head 120 is provided in the knife groove 130. The knife head 120 can be installed in the knife groove 130 by welding, and multiple knife heads 120 are evenly provided on each substrate 110 to improve the scraping efficiency. The area between two adjacent knife heads 120 is the side wall of the regular polygonal plate. Compared with the circular plate, the space between two adjacent knife heads 120 is larger, and the wood chips generated by scraping can be withdrawn along the side wall of the regular polygon, and the wood chips are not easy to be blocked. The side wall of the regular polygon is equivalent to the chip withdrawal surface.

[0038] In practice, the cutter head 120 can extend along the radial direction of the base plate 110, and the arrangement is simple. The cutter head 120 can also be inclined with respect to the radial direction of the base plate 110, so that when the peeling tool 100 rotates, the cutter head 120 gradually contacts the bark, so that the vibration of the entire peeling tool 100 is small, and the whole machine is easier to hold.

[0039] The second aspect of the present application provides a skin scraping extension assembly 200, such as Figure 3As shown, it includes an extension shell 250, an extension shaft 300, a first bevel gear 350 and a second bevel gear 400, wherein the extension shell 250 is a structure for installing and supporting other components, the extension shaft 300 can achieve the extension of the tool, and the first bevel gear 350 and the second bevel gear 400 can realize the rotation transmission in two vertical directions.

[0040] like Figure 3 , Figure 4 and Figure 5 As shown, the extension shell 250 includes a left half shell 260 and a right half shell 270, which are buckled together to facilitate the installation of the components inside. The left half shell 260 and the right half shell 270 can be provided with a threaded connection structure, and after the two are buckled together, they can be connected by screws, and the connection is more secure. An oil filling hole can be provided on the right half shell 270 and plugged with a rubber plug. After a period of use, lubricating oil can be added to the meshing portion of the first bevel gear 350 and the second bevel gear 400.

[0041] like Figure 3 As shown, the extension shaft 300 is rotatably connected to the extension shell 250, and a bearing can be arranged in the extension shell 250 to achieve the rotatable connection. The first end of the extension shaft 300 is used to connect to the motor, so that the motor can drive the extension shaft 300 to rotate.

[0042] like Figure 3 As shown, the first bevel gear 350 is connected to the second end of the extension shaft 300, the second bevel gear 400 is meshed with the first bevel gear 350, and a structure for mounting the substrate 110 of the first aspect is provided on the second bevel gear 400. In this way, when the motor is started, the extension shaft 300 and the first bevel gear 350 can be driven to rotate, and then the second bevel gear 400 can be driven to rotate, so that the substrate 110 can rotate with the second bevel gear 400, and the skin scraping tool 100 is driven.

[0043] When in use, the first end of the extension shaft 300 can be connected to the motor, the second end of the extension shaft 300 is connected to the first bevel gear 350, the first bevel gear 350 is meshed with the second bevel gear 400, and the scraping tool 100 of the first aspect can be installed on the second bevel gear 400. When the motor is started, the scraping tool 100 can scrape the bark, and the extension shell 250 and the extension shaft 300 are relatively slender relative to the whole machine. Through the extension shaft 300, the scraping tool 100 can be extended into the corners of the tree for scraping, thereby achieving scraping at the corners of the tree.

[0044] Compared with the prior art, the scraping extension assembly 200 can connect the motor and the scraping tool 100, thereby driving the scraping tool 100 to rotate, and the extension shaft 300 can enable the scraping tool 100 to extend into the corners of the tree for scraping, thereby avoiding the situation where the existing scraping equipment cannot extend into the corners of the tree due to the large size of the whole machine or uses the scraper for manual scraping, thereby achieving scraping at the corners of the tree, improving scraping efficiency and reducing labor intensity.

[0045] In some embodiments, Figure 4 As shown, a gear installation cavity 261 is provided at one end of the left half shell 260 away from the motor, and the second bevel gear 400 is rotatably connected in the gear installation cavity 261 through a bearing, thereby realizing the rotatable connection of the second bevel gear 400.

[0046] In some embodiments, Figure 6 As shown, the second bevel gear 400 is provided with a central threaded hole 410, and the base plate 110 is mounted on the central threaded hole 410 by bolts. The bolts pass through the mounting holes 111 of the base plate 110 and are screwed into the central threaded hole 410, thereby firmly mounting the base plate 110 on the second bevel gear 400, thereby realizing the installation of the scraping tool 100.

[0047] The third aspect of the present application provides a tree horn bark scraper 500, such as Figure 7 and Figure 8 As shown, it includes a shell 550, a scraping tool 100 of the first aspect, and a scraping extension assembly 200 of the second aspect, wherein the shell 550 is a structure for installing and supporting other components, the scraping tool 100 can scrape the bark of trees, and the scraping extension assembly 200 can extend the scraping tool 100.

[0048] like Fig. 9 As shown, a driving motor 560 and a power supply 570 are provided in the housing 550, and the driving motor 560 is electrically connected to the power supply 570 to realize power supply of the driving motor 560. The extension shell 250 is installed on the housing 550, and the extension shaft 300 is connected to the output shaft of the driving motor 560 by transmission, for example, the connection can be realized by a coupling, so that the peeling extension assembly 200 is installed on the housing 550 and is connected to the driving motor 560 by transmission. The base plate 110 is installed on the second bevel gear 400. When the driving motor 560 is started, the extension shaft 300 can be driven to rotate, and then the peeling tool 100 is driven by the meshing of the first bevel gear 350 and the second bevel gear 400, so as to realize the peeling function of the tree horn peeling machine 500.

[0049] When in use, the tree corner scraper 500 can not only scrape the bark of the tree trunk normally, but also through the scraping extension component 200 of the second aspect, the scraping tool 100 of the first aspect can be extended into the tree corner for scraping, thereby achieving scraping of the bark at the tree corner.

[0050] Compared with the existing technology, the tree corner scraper 500 can scrape the bark of the tree trunk and the tree corner, avoiding the situation that the existing scraping equipment cannot reach the tree corner due to the large size of the whole machine or the scraping is done manually with a scraper, thereby achieving scraping of the tree corner, improving scraping efficiency and reducing labor intensity.

[0051] In some embodiments, Fig. 9 As shown, the shell 550 includes a left shell 580, a right shell 590 and a bottom shell 600. The left shell 580 and the right shell 590 are buckled together, and the bottom shell 600 is buckled on the left shell 580 and the right shell 590, so that the shell 550 forms a detachable and installable structure, which is convenient for the installation of its internal components.

[0052] like Figure 4 and Fig. 9 As shown, the left half shell 260 is provided with a mounting plate 262, the mounting plate 262 is provided with an extended mounting hole 263, the left shell 580 is provided with a mounting threaded hole 581, and the right shell 590 is provided with a mounting through hole 591. The extended mounting hole 263, the mounting threaded hole 581 and the mounting through hole 591 are opposite to each other and connected by bolts, so that the extended shell 250 is installed in the shell 550. In practice, the right half shell 270 is also provided with a mounting plate 262 and an extended mounting hole 263.

[0053] like Figure 4 and Fig. 9 As shown, a ring plate 264 is provided at the bottom of the left half shell 260, and a motor mounting hole 265 is provided on the ring plate 264. A motor threaded hole 561 is provided at the top of the drive motor 560. The motor threaded hole 561 is opposite to the motor mounting hole 265 and connected by bolts to achieve the installation and fixation of the drive motor 560. The left shell 580 and the right shell 590 can be provided with heat dissipation holes at positions relative to the drive motor 560 to achieve heat dissipation.

[0054] In some embodiments, Fig.10As shown, the housing 550 is provided with a mounting slide hole 551, and the mounting slide hole 551 is provided with a switch 610 and a push plate 620, the switch 610 is electrically connected to the drive motor 560, the push plate 620 is connected to the switch 610, and the push plate 620 is slidably connected to the mounting slide hole 551. When the push plate 620 is pushed, the switch 610 can be controlled to be turned on and off, thereby controlling the turning on and off of the drive motor 560. In implementation, the mounting slide hole 551 can be provided with half holes on the left housing 580 and the right housing 590, and the left housing 580 and the right housing 590 are buckled together to form a complete mounting slide hole 551.

[0055] like Fig.10 As shown, the push plate 620 is provided with a pressing installation hole 621, and a spring 630 and a pressing shaft 640 are provided in the pressing installation hole 621. The pressing shaft 640 passes through the spring 630 and is slidably connected in the pressing installation hole 621. A limiting shaft 641 is provided at the end of the pressing shaft 640. A limiting groove 592 is provided on the housing 550. The limiting shaft 641 cooperates with the limiting groove 592. When the limiting shaft 641 cooperates with the limiting groove 592, the push plate 620 cannot slide. When the pressing shaft 640 is pressed, the limiting shaft 641 separates from the limiting groove 592, the limiting effect is released, and the push plate 620 can slide. In this way, the push plate 620 can only move when the pressing shaft 640 is pressed, avoiding misoperation and improving safety.

[0056] In some embodiments, Fig.11 As shown, the tree horn scraper 500 further includes a semicircular shield 650, which is generally a rotating body structure. The semicircular shield 650 is rotatably connected to the left half shell 260 (specifically, the gear installation cavity 261), and is axially limited by a retaining spring, so that the semicircular shield 650 can only rotate, but cannot move along the axial direction of the gear installation cavity 261. The semicircular shield 650 covers the scraping tool 100, and about half of the scraping tool 100 is exposed, so that the scraping of the tree can be achieved and wood chips can be prevented from splashing.

[0057] like Figure 4 and Fig.11 As shown, the gear installation cavity 261 is provided with a plurality of positioning grooves 266 along its circumferential direction, and a bumping ball 660 is provided in the semicircular shield 650, and the bumping ball 660 can cooperate with any positioning groove 266 for positioning, and when the bumping ball 660 cooperates with the positioning groove 266, the shield no longer rotates by itself. The bumping ball 660 is a finished product part available on the market, generally composed of a steel ball, a spring and a cylinder, etc. The steel ball is connected to the spring, and the spring is installed in the cylinder, so that the steel ball can be extended and retracted along the axial direction of the cylinder.

[0058] When the operator manually applies external force to rotate the semicircular shield 650, the telescopic end of the bead 660 is squeezed by the positioning groove 266 and retracts, so that the entire semicircular shield 650 can be rotated until the telescopic end of the bead 660 rotates to the next positioning groove 266 and extends out. The bead 660 cooperates with the new positioning groove 266 again to achieve the angular rotation of the semicircular shield 650 and fix it at the required position, which can correspond to the corners of the tree to be scraped by the scraping tool 100, can better prevent wood chips from splashing, and improve the applicable working conditions and scope of application.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
