Description

[0001] This application, entitled "A bark scraping tool and device", claims priority to Chinese patent application No. 2024215532039, filed with the State Intellectual Property Office on July 3, 2024, entitled "A bark scraping tool", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of cutting tool technology, specifically to a bark scraping tool and device. Background Technology

[0003] As trees age, their bark rots, especially fruit trees. In recent years, apple, pear, and peach trees have been particularly severely affected by bacterial infections. If not scraped off in time, the damage will worsen and eventually lead to death. Timely removal of rotten bark prevents moisture from accumulating in the rotten areas, thus preventing further decay. It also helps prevent the growth of pests and diseases, promoting healthy tree growth. For many years, fruit farmers have used manual scrapers to remove rot, which is not only inefficient but also extremely laborious. Existing bark scraping tools are complex and difficult to manufacture, and they cannot simultaneously remove bark from large areas or from branching and bending sections, making them impractical. Utility Model Content

[0004] The purpose of this utility model is to provide a bark scraping tool to solve the technical problems of existing bark scraping tools in the background art, which are not practical because they are complex in structure and difficult to process, and cannot simultaneously remove bark from large areas and local branches and bends.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bark scraper includes a blade disc, a stepped groove is provided at the center of the blade disc, a circular hole is provided at the center of the stepped groove, a groove is provided at the edge of the blade disc, a bolt hole is provided on the side of the groove, a bolt is passed through the bolt hole, a blade is passed through the bolt, the blade is detachably set in the groove by a nut on the bolt, and the cutting edge of the blade extends out of the end face and edge of the blade disc.

[0006] Furthermore, the blade is provided with chip removal grooves.

[0007] Furthermore, it also includes an upper pressure plate and a lower pressure plate. The stepped grooves are symmetrically arranged on the upper and lower sides of the cutter head. The upper pressure plate and the lower pressure plate are respectively installed in the stepped grooves on the upper and lower sides of the cutter head. The lower pressure plate is provided with a protrusion, and the motor output shaft is provided with a flat plate. When the cutter head equipped with the upper pressure plate and the lower pressure plate is tightened onto the motor output shaft by the upper pressure plate, the protrusion and the flat plate are locked together to achieve a fixed connection between the cutter head and the motor output shaft, and / or synchronous rotation.

[0008] Furthermore, the grooves are evenly spaced at the edge of the cutter head.

[0009] Furthermore, it also includes a spring washer, which is fitted onto the bolt and located between the bolt head and the outside of the bolt hole.

[0010] Furthermore, the edge of the cutter head is an arc-shaped edge.

[0011] This utility model also provides a device that uses the aforementioned bark scraping knife.

[0012] The beneficial effects of this utility model are:

[0013] This utility model discloses a bark scraper. Because the blade's cutting edge extends beyond the end face and edge of the blade disc, the end face of the blade disc is aligned with the bark during scraping, allowing for large-area bark removal. When scraping bark from branch forks or bends, the blade disc is held vertically; since the blade's cutting edge protrudes from the edge of the blade disc, it can remove bark from curved or small areas of the tree. This utility model has a relatively simple structure, is easy to manufacture, and can simultaneously meet the needs of scraping bark from large areas and localized branch forks and bends, significantly improving its practicality.

[0014] After the blade of this utility model wears out, the blade can be replaced by unscrewing the nut or by loosening the nut, rotating the blade, and then tightening the nut to continue using it. In this way, the unworn blade can continue to work, thereby reducing blade consumption. Attached Figure Description

Detailed Implementation

[0026] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "set," "install," "connect," "link," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] The following is combined Figures 1-6 The technical solution provided by this utility model will be described in more detail.

[0028] Example 1

[0029] See Figure 1 , Figure 2 , Figure 9 as well as Figure 10 This embodiment 1 provides a bark scraper, including a circular blade 1. A stepped groove 3 is provided at the center of the blade 1. The stepped groove 3 serves as clearance for mounting the blade 1, ensuring that components used to assemble the blade 1 do not extend beyond the end face of the blade 1 after installation, thus facilitating the bark removal operation on the end face of the blade 1. A circular hole 2 for connection is provided at the center of the stepped groove 3. Multiple grooves 4 are evenly spaced along the edge of the blade 1. Specifically, they can be... Figure 1 There are four grooves in the center. The groove 4 is rectangular and extends axially through both ends of the cutter head 1.

[0030] Bolt holes 5 are provided on the side of the groove 4, and bolts 6 are inserted through the bolt holes 5. A blade 7 is inserted through a through hole 71 on the bolt 6. The blade 7 is detachably mounted in the groove 4 by a nut 8 on the bolt 6. Specifically, it is detachable by tightening the nut 8 on the bolt 6 to fix the blade 7, and by unscrewing the nut 8 to remove the blade 7. The cutting edge of the blade 7 extends beyond the end face and edge of the cutter head 1. Specifically, the blade 7 is frustum-shaped, with its large circle serving as the cutting edge, and a conical structure from the large circle to the small circle. The cutting edge (large circle) extends beyond the end face and edge of the cutter head 1, while the small circle may not extend. This design ensures a smooth transition between the cutting edge (large circle) of the blade 7 and the corresponding small circle position on the cutter head 1. During bark scraping, there is no abruptness when the cutter head contacts the bark, allowing for smooth bark scraping and improving the efficiency and effectiveness of the bark scraping operation.

[0031] In addition, the cutting tool also includes a spring washer 61. The spring washer 61 is fitted onto the bolt 6 and located between the head of the bolt 6 and the outside of the bolt hole 5. The function of the spring washer 61 is to provide tension for the installation of the blade 7 after it is installed, so that the blade 7 is not easy to loosen after installation.

[0032] Meanwhile, the edge of the blade 1 is designed as an arc edge 11, which helps to scrape the bark more smoothly and reduce damage to the tree.

[0033] In this embodiment 1, the bark scraper is used by connecting the circular hole 2 to the output shaft of the motor.

[0034] The specific connection can be made in the following ways:

[0035] 1. The circular hole 2 can be welded to the output shaft of the motor. After welding, it must be ensured that the output shaft of the motor does not extend beyond the end face of the cutter head 1.

[0036] 2. The cutter head 1 can be tightened onto the output shaft of the motor using a nut. After tightening, the nut is located in the stepped groove 3 on the cutter head 1 and does not extend beyond the end face of the cutter head 1. This connection method facilitates the installation and disassembly of the cutter head 1, and makes subsequent maintenance and replacement convenient.

[0037] 3. The interference fit between the circular hole 2 of the cutter head 1 and the motor output shaft allows for a tight fit between the cutter head 1 and the motor output shaft, thereby transmitting torque. Specifically, the cutter head 1 can be press-fitted onto the motor output shaft using methods such as press-fitting or temperature difference. To facilitate disassembly and prevent axial movement of the cutter head 1, elastic retaining rings or other components can be installed in the stepped groove 3. The elastic retaining rings should not extend beyond the end face of the cutter head.

[0038] After connection is complete, bark scraping can begin. When large areas of bark need to be removed, the operator can align the end face of the cutter head 1 with the bark and use the motor's output shaft to rotate the cutter head 1, thereby efficiently completing the large-area bark removal work.

[0039] When faced with complex parts such as branching or bending of branches, or when only a small area of ​​bark needs to be removed, the operator can stand the blade 1 vertically and use the blade 7 with its protruding curved edge to peel the bark from the bent or small area.

[0040] Example 2

[0041] The connection between the circular hole 2 of the bark scraper in Example 1 and the output shaft of the motor has been improved.

[0042] See details Figure 3 , Figure 4 The bark scraper also includes an upper pressure plate 91 and a lower pressure plate 92. Stepped grooves 3 are symmetrically arranged on the upper and lower surfaces of the cutter head 1. The upper pressure plate 91 and lower pressure plate 92 are respectively installed in the stepped grooves 3 on the upper and lower surfaces of the cutter head 1. The lower pressure plate 92 has a protrusion 921, and the motor output shaft 101 has a flat plate 102. The flat plate 102 is welded to the motor output shaft 101, integrally connected, or fixedly connected in other ways. When the cutter head 1 equipped with the upper pressure plate 91 and lower pressure plate 92 is tightened onto the motor output shaft 101 via the upper pressure plate 91, the protrusion 921 and the flat plate 102 interlock, thereby achieving a fixed connection between the cutter head 1 and the motor output shaft 101. The specific tightening method is as follows: A wrench hole 911 is provided on the upper pressure plate 91. A four-jaw wrench or needle-nose pliers is used to tighten the wrench hole 911, thereby tightening the upper pressure plate 91 to the motor output shaft 101 (the motor output shaft 101 is threadedly connected to the upper pressure plate 91). After tightening, the protrusion 921 on the lower pressure plate 92 will engage with the flat plate 102 on the motor output shaft 101, thus achieving a fixed connection between the cutter head 1 and the motor output shaft 101, and as... Figure 3 As shown, the upper pressure plate 91, after being tightened, does not extend beyond the end face of the cutter head 1.

[0043] In actual use, when the motor 10 is started (the motor 10 can be a device provided in this application for using the above-mentioned cutting tool), the motor output shaft 101 of the motor 10 begins to rotate. Since the motor output shaft 101 is fixedly connected to the flat plate 102, and the flat plate 102 and the protrusion 921 are in a locked state, the cutting disc 1 will rotate synchronously, thereby performing scraping operations.

[0044] This embodiment improves upon embodiment 1 by modifying blade 7. Specifically, as follows... Figures 5-8 As shown, a chip removal groove 72 has been added to the blade 7. Figure 6 The blade shown is equipped with an angled chip removal groove. In fact, the chip removal groove 72 can also be designed as... Figure 7 The blade shown has vertical chip grooves and Figure 8The blade shown has a transverse chip removal groove, and the chip removal function of the three types of grooves is arranged from smallest to largest as follows: transverse chip removal groove, vertical chip removal groove, and oblique chip removal groove, to adapt to the bark characteristics of different trees.

[0045] For trees with thin bark, a transverse chip removal groove can be used. The direction of the transverse chip removal groove is parallel to the circles of the upper and lower bottom surfaces of the blade 7. It is perpendicular to the rotation direction of the cutter head 1. Figure 5 The arrow in the diagram indicates the direction of rotation, and its chip removal function is relatively weak. During the scraping of thin bark, because the bark itself is thin, the amount of chips produced is relatively small, and the chip accumulation rate is slow. This avoids accidental damage to the tree body that may be caused by excessively rapid chip removal, thus protecting the tree to the greatest extent while ensuring the basic chip removal function.

[0046] For trees with thicker bark, the angled chip removal groove offers a significant advantage. The groove's angle is carefully designed to align with the direction of chip removal during bark scraping. When scraping thick bark, a large amount of chip is generated; the angled groove allows the chip to slide smoothly out along its angle, effectively preventing chip accumulation around the blade 7. This ensures the blade 7 remains sharp throughout the cutting process, reducing increased cutting resistance and blade wear caused by chip accumulation, thus significantly improving the efficiency and quality of bark scraping. Figure 7 The vertical chip removal groove shown has a function that falls between that of a horizontal chip removal groove and an oblique chip removal groove.

[0047] Finally, it should be noted that the cutter head 1 of this utility model may not have the stepped groove 3. The circular hole 2 can also be replaced with other shapes of flat holes to adapt to the flatness of the motor output shaft, such as square flat holes, hexagonal flat holes, etc. The specific shape can be customized according to the size and shape of the flatness of the motor output shaft to ensure a fixed connection between the cutter head 1 and the motor output shaft, thereby realizing the scraping function of the cutter. In addition, the blade 7 can also be replaced with different types, as long as it can achieve the purpose of scraping bark of this utility model.

[0048] The above description is merely a specific embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
