Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a camphor tree trunk cutting machine. Background Technology

[0002] In the production of camphor tree essential oil, the pretreatment of raw materials (leaves and branches) is crucial. To ensure efficient and high-quality oil extraction, the pretreatment of raw materials must meet certain standards. Traditionally, people rely on manual cutting of branches using tools such as saws, but this method has significant drawbacks. First, manual cutting is extremely inefficient, time-consuming, and labor-intensive, especially in large-scale production. Second, due to inconsistencies in manual operation, it is difficult to standardize the cutting size, which directly affects the consistency of raw materials in the essential oil extraction process. Inconsistent raw material sizes lead to fluctuations in essential oil quality, thus affecting the yield and market value of the essential oil.

[0003] To address these issues, some branch-cutting devices have emerged on the market, such as the garden branch-pruning device disclosed in Chinese patent "CN108934537A". These devices aim to improve the efficiency and aesthetics of garden pruning, but they often have limitations. These devices are typically large, lack flexibility, and are difficult to adapt to the complex and varied growth positions of camphor tree branches. In the essential oil production process, there are strict requirements for the precise cutting length and angle of branches, and existing equipment often struggles to meet these delicate technological demands. Therefore, developing a branch-cutting device that can meet both the needs of garden pruning and the specific requirements of camphor tree essential oil production has become an urgent need in the industry.

[0029] Example 1

[0030] Please see Figure 1This utility model provides a camphor tree trunk cutting machine. In the current technical field, camphor tree branch cutting relies heavily on traditional manual operation or fixed cutting equipment. These traditional devices are often limited by their design and cannot effectively handle camphor tree branches of varying heights and shapes. Especially in dense or complex growing environments, operators often need to spend a lot of time and effort adjusting the position and angle of the cutting equipment to accommodate branches of different heights. This not only increases the difficulty of operation but also significantly reduces the efficiency of the cutting operation.

[0031] This invention aims to solve the problem of low cutting efficiency when cutting camphor tree branches. The uneven cutting heights make it difficult for cutting equipment to adapt to various complex and changing growth environments. This invention proposes a new solution that improves the cutting equipment to accommodate branches of different heights, thereby increasing overall cutting efficiency.

[0032] Furthermore, this utility model embodiment provides a camphor tree trunk cutting machine, including a base 100, a support assembly, and a cutting assembly. The base 100 is used to connect external equipment to realize movement or position adjustment in the work area. This external equipment can be a mobile trolley, a tracked mobile platform, or other forms of automated mobile equipment. The support assembly is disposed on the base 100 and includes an adjustment part and an extension part; the adjustment part is hinged to the extension part; the cutting assembly includes a mounting base 310 connected to the extension part and a cutting part 320 disposed on the mounting base 310; the cutting part 320 can rotate based on the mounting base 310; wherein, the cutting part 320 is further provided with a first cylinder 311 for adjusting the cutting angle, the first cylinder 311 is hinged to the cutting part 320, and the cutting angle of the cutting part 320 is adjusted by extending or retracting the piston rod of the first cylinder 311.

[0033] Furthermore, by mounting the base 100 on an external device, the operator can easily move the entire cutting machine to the designated work position. The base 100 is designed to be both stable and flexible, allowing connection to various external devices. Since the areas and terrains where camphor trees are planted vary greatly, and different areas generally have their own methods of movement, this embodiment does not limit or specify the method of movement. The hinged design of the adjustment section and extension section of the support assembly allows the cutting machine to be flexibly adjusted according to different branch heights and angles. By operating the adjustment section, the extension section can extend upwards or downwards to accommodate branches of different heights, greatly enhancing the applicability and flexibility of the cutting machine.

[0034] The mounting base 310 of the cutting assembly is tightly connected to the extension, ensuring the stability and accuracy of the cutting unit 320. The cutting unit 320 can not only rotate horizontally based on the mounting base 310 to accommodate different angles of the branches, but also achieves fine adjustment of the cutting angle through the extension or retraction of the piston rod of the first cylinder 311. This design makes the cutting operation more precise, effectively avoiding incomplete cuts or damage to the tree trunk caused by improper angles.

[0035] In use, the cutting machine is transported to a designated location. By setting the adjustment section and the extension section, the cutting limit position of the cutting machine in this embodiment is extended. When the cutting section 320 is extended to the expected cutting position, the cutting section 320 is activated to cut the branches of the camphor tree and the cut branches are collected.

[0036] Further, please see Figure 1 and Figure 2 The adjustment section includes a first adjustment segment and a second adjustment segment; the first adjustment segment and the second adjustment segment are respectively provided with a first adjustment arm 111 and a second adjustment arm 112, as well as a second cylinder 121 and a third cylinder 122 for adjusting the support angle between the first adjustment arm 111 and the second adjustment arm 112, the adjustment section and the extension.

[0037] The first adjusting arm 111 and the second adjusting arm 112, the adjusting part and the extension part are respectively provided with a first auxiliary hinge and a second auxiliary hinge.

[0038] The first and second adjustment sections are mainly set up to adjust the cutting angle of the cutting machine. Since the growth height of camphor trees varies, their cutting requirements are also different. Therefore, in this embodiment, the cutting angle can be flexibly adjusted by the cooperation of the first and second adjustment sections.

[0039] The piston rods of the second cylinder 121 and the third cylinder 122 extend or retract, pushing or pulling the first adjusting arm 111 and the second adjusting arm 112, thereby changing the support angle between the adjusting part and the extension part, and achieving fine adjustment of the cutting angle. This design allows the cutting machine to maintain the optimal cutting angle when facing camphor trees of different heights, improving cutting efficiency and cutting quality. Simultaneously, the provision of the first and second auxiliary hinges enhances the stability and durability of the connection, ensuring the stability and reliability of the cutting machine during long-term use.

[0040] In operation, the operator can adjust the positions of the first adjusting arm 111 and the second adjusting arm 112 by controlling the extension or retraction of the piston rods of the second cylinder 121 and the third cylinder 122, based on the actual height of the camphor tree, thereby achieving the desired cutting angle. This flexibility and precision makes the cutting operation more efficient and reduces the labor intensity of the operator. After adjustment, the cutting unit 320 is activated, and the cutting machine can precisely cut the branches of the camphor tree at the preset cutting angle. The cut branches are then collected by a collection device for subsequent processing and utilization.

[0041] Further, please see Figure 2 The first auxiliary hinge part includes a first hinge rod 123 disposed on the first adjusting arm 111 and a second hinge rod 124 disposed at one end of the second adjusting arm 112; hinge blocks 125 are respectively provided at both ends of the first hinge rod 123 and the second hinge rod 124; a first connecting rod 126 is provided on the piston rod of the second cylinder 121; the first hinge rod 123 and the second hinge rod 124 are respectively hinged to the first connecting rod 126 through the hinge blocks 125.

[0042] The second auxiliary hinge portion includes a third hinge rod 131 disposed at one end of the second adjusting arm 112 and a fourth hinge rod 132 disposed at the extension portion; a second connecting rod 133 is provided on the fourth hinge rod 132 through a connecting block 134; the third hinge rod 131 and the second connecting rod 133 are hinged through the hinge block 125; the third cylinder 122 is hinged to the second connecting rod 133.

[0043] The first auxiliary hinge and the second auxiliary hinge are used to assist in the stability of the movement between the first adjustment section and the second adjustment section, and between the second adjustment section and the extension.

[0044] When in use, when the piston rod of the second cylinder 121 extends, it pushes the first hinge rod 123 and the second hinge rod 124 through the first connecting rod 126, causing the first adjusting arm 111 and the second adjusting arm 112 to rotate around the first auxiliary hinge part as the axis, thereby changing the support angle between the adjusting part and the extension part.

[0045] Simultaneously, the piston rod of the third cylinder 122 also pushes the third hinge rod 131 through the second connecting rod 133, causing the angle between the second adjusting arm 112 and the extension to change. This linked adjustment method not only improves the accuracy of the cutting elevation angle adjustment but also ensures the stability of the cutting machine during the adjustment process.

[0046] Under the action of the first and second auxiliary hinges, the connection between the first adjusting arm 111 and the second adjusting arm 112, the adjusting part and the extension part is more secure, and a stable cutting angle can be maintained even when facing complex cutting environments. In addition, the design of the hinge block 125 and the connecting rod makes the adjustment process smoother, reduces resistance and friction during adjustment, and extends the service life of the cutting machine.

[0047] During the cutting operation, the operator can easily adjust the cutting angle by controlling the extension or retraction of the piston rod of the cylinder, based on the actual height of the camphor tree. This design not only improves the flexibility of the cutting operation but also reduces the labor intensity of the operator, making the cutting operation more efficient and safer.

[0048] Further, please see Figure 1 and Figure 5 The extension includes an extension body 210 and a multi-stage telescopic arm that is sequentially mounted; the multi-stage telescopic arm includes a first telescopic arm 220, a second telescopic arm 230 and a third telescopic arm 240.

[0049] Furthermore, the first telescopic arm 220 is slidably fitted inside the extension body 210, the second telescopic arm 230 is slidably fitted inside the first telescopic arm 220, and the third telescopic arm 240 is slidably fitted inside the second telescopic arm 230; a first driving cylinder 251 is provided between the extension body 210 and the first telescopic arm 220, a second driving cylinder 252 is provided between the first telescopic arm 220 and the second telescopic arm 230, and a third driving cylinder 253 is provided between the second telescopic arm 230 and the third telescopic arm 240; through the coordinated driving of the first driving cylinder 251, the second driving cylinder 252, and the third driving cylinder 253, the multi-stage telescopic arms can be extended or retracted step by step to adjust the total length of the extension.

[0050] The multi-stage telescopic arm is designed to enable the cutting machine to cover a greater cutting height or cutting range.

[0051] In operation, the cutting angle of the cutter is first adjusted using the first and second adjustment sections to align the cutting section 320 with the branch of the camphor tree to be cut. Then, based on the actual height of the camphor tree, the extension or retraction of the multi-stage telescopic arm is adjusted by controlling the extension or retraction length of the piston rods of the first drive cylinder 251, the second drive cylinder 252, and / or the third drive cylinder 253, thereby adjusting the total length of the extension section. This design allows the cutter to flexibly adapt to camphor trees of different heights, ensuring that the cutting section 320 always accurately contacts the area to be cut. Simultaneously, the progressive extension or retraction of the multi-stage telescopic arm ensures the stability and reliability of the cutter during adjustment, avoiding cutting errors or safety accidents caused by improper adjustment. After adjustment, the operator can start the cutting section 320 to perform the cutting operation. The cut branches are then collected and processed using a collection device.

[0052] Furthermore, the extension body 210, the first telescopic arm 220, and the second telescopic arm 230 are all provided with inner cylinders to facilitate installation and cooperation with other arms; wherein, the cross-section of the inner cylinder is rectangular, rhomboid, or circular, and the first telescopic arm 220, the second telescopic arm 230, and the third telescopic arm 240 are adapted to it.

[0053] Furthermore, the cutting part 320 includes a first cutter 321 and a second cutter 322 disposed on both sides of the mounting base 310. The first cutter 321 and the second cutter 322 are spaced apart, and both can rotate based on the mounting base 310 to perform the cutting action.

[0054] In practical applications, operators can flexibly handle branches of different shapes and sizes by adjusting the rotation angles of the first cutter 321 and the second cutter 322 according to actual needs. This dual-cutter design not only improves cutting efficiency but also ensures the flatness and smoothness of the cut surface, reducing the difficulty of subsequent processing. Simultaneously, the spacing between the first cutter 321 and the second cutter 322 avoids mutual interference and ensures the continuity of cutting, making the entire cutting process smoother and more efficient. During use, operators only need to operate the control device to easily achieve the rotation and cutting actions of the cutters, greatly simplifying the operation process and improving work efficiency.

[0055] In actual operation, the first cutter 321 and / or the second cutter 322 need to be activated first. When the branch is subjected to uniform force during the cutting process and the cutting task is relatively simple, the operator can activate only one cutter to perform a precise cut on the branch at the expected cutting location. However, in some cases, if the cutting area is difficult to bear force, or if the cutting process is more complex and difficult, the operator can choose to activate both cutters simultaneously. The cooperative force between the two cutting heads can effectively clamp the branch, which not only improves the cutting efficiency but also ensures the smooth progress of the cutting process, thereby achieving better work results.

[0056] Please see Figure 3 and Figure 4 The first cutter 321 and the second cutter 322 are respectively connected to the mounting base 310 through a hinge structure, and are provided with a first cylinder 311 and a fourth cylinder 323 for controlling the cutting angle of the first cutter 321 and the second cutter 322.

[0057] During installation, the installation angles of the first cutter 321 and the second cutter 322 are fixed. However, for scenarios where the cutting angle needs to be adjusted, the cutting range and cutting angle between the first cutter 321 and the second cutter 322 can be controlled according to the operation of the first cylinder 311 and the fourth cylinder 323. This can adapt to branches of different diameters and shapes, improving the versatility and flexibility of the cutter.

[0058] Furthermore, the cylinder control ensures accurate cutting angles, resulting in smoother cut surfaces and reduced post-cutting trimming. This design also allows the cutter to flexibly adjust its cutting strategy when dealing with complex tree structures, effectively preventing damage or incomplete cuts caused by improper cutting angles, further improving the efficiency and effectiveness of the cutting operation.

[0059] The mounting base 310 is provided with a protective member 324, which has an opening to allow the tree trunk to enter the cutting range; the protective member 324 is used to prevent the tree trunk from coming out of the cutting position in the vertical direction during cutting.

[0060] When the tree trunk is being cut, if the trunk tends to move out of the cutting area due to the cutting force or its own weight, the protective component 324 will be compressed and effectively prevent the trunk from falling out of the cutting position, ensuring the stability and safety of the cutting process. Furthermore, the opening edge of the protective component 324 is designed with a smooth and somewhat guiding structure. This reduces friction and damage to the trunk surface when guiding the trunk into the cutting area, and also allows the trunk to enter the predetermined cutting position more smoothly, further improving the smoothness and efficiency of the cutting operation.

[0061] Example 2

[0062] Please see Figure 3 and Figure 4 This utility model embodiment provides a camphor tree trunk cutting machine. In this embodiment, an opening is provided at the bottom of the mounting base 310, and a third cutting head 325 is provided through the opening. The cutting head is partially disposed inside the mounting base 310, and a portion protrudes from the mounting base 310 and can rotate based on the mounting base 310.

[0063] The third cutting head 325 can cut the bottom of the camphor tree trunk. This design allows for a more comprehensive cutting operation, enabling not only the cutting of the main body of the trunk but also effective treatment of the bottom, ensuring that the cut trunk is neat and flat, facilitating subsequent collection and processing.

[0064] Meanwhile, the third cutting head 325 allows for flexible adjustment of the cutting angle and position according to different cutting needs, further enhancing the flexibility and applicability of the cutting operation. Furthermore, the inclusion of the third cutting head 325 also improves the overall stability and cutting effect of the cutting machine, making the cutting operation more efficient and safer.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
