Description

Technical Field

[0001] This utility model belongs to the field of forestry machinery technology, specifically relating to a cutting device for cutting tree branches horizontally. Background Technology

[0002] When propagating seedlings by cuttings, longer cuttings need to be cut into shorter buds. Currently, pruning shears are mostly used to cut buds, which is time-consuming, labor-intensive, and inefficient.

[0003] Existing intelligent cutting machines are complex in structure, inconvenient to move, and expensive, making them unsuitable for small-scale planting. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for cutting tree branches, such as Polygonum hydropiper and Tamarix chinensis, to overcome the shortcomings of the existing technology.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A cutting device for cutting tree branches includes a working platform, a driving device, and a circular saw. The working platform is provided with a through groove for the circular saw to pass through. The upper part of the circular saw is exposed above the working platform, and the lower part is located below the working platform. The driving device is connected to the circular saw and is used to drive the circular saw to rotate and cut the branches.

[0007] The work platform has four support columns at its four corners. Two of the support columns on one side have a caster behind them, and two of the support columns on the other side have a pull rod in front of them.

[0023] The cutting device for horizontally pruning tree branches provided in this application, such as Figure 1 As shown, the device includes a working platform 1, a drive unit 2, and a circular saw 3. The working platform 1 has a through slot through which the circular saw 2 passes. The upper part of the circular saw is exposed above the working platform, and the lower part is located below the working platform. That is, the circular saw of this application is located in the through slot, with only the upper part exposed on the working platform, for contacting the branches to cut them.

[0024] The drive unit 2 is connected to the circular saw and is used to drive the circular saw 3 to rotate and cut branches. The drive unit is preferably located below the working platform.

[0025] When using this application, the circular saw is started, and the operator holds a bundle of long branches, then moves forward along the work platform until they come into contact with the circular saw. As the circular saw rotates, it cuts the long branches into smaller segments. Because the circular saw can automatically cut multiple branches at a time, it greatly improves cutting efficiency and reduces production costs.

[0026] As will be understood by those skilled in the art, the drive unit and the circular saw can be made using conventional technology. In particular, the circular saw should be a circular saw with safety protection functions, such as a protective cover and an emergency braking system.

[0027] Preferably, the cutting device provided in this application further includes a protective cover assembly; the protective cover assembly includes an upper protective cover 10 and a lower protective cover 13, wherein the upper protective cover 10 covers the upper end area of ​​the circular saw 3 and the non-feeding end area of ​​the circular saw. The upper protective cover located at the upper end can prevent people, other materials, etc. from contacting the circular saw from above, while also having a certain space with the working platform so as not to affect the feeding. The upper protective cover located at the rear end is in the non-feeding direction, which can prevent people, other materials, etc. from contacting the circular saw from the rear end, while also not affecting the operator from moving forward with a long branch from the feeding side to contact the circular saw.

[0028] The lower protective cover 13 is installed in the circular saw area located below the work platform to prevent the lower circular saw from being exposed. Therefore, the protective cover assembly installed in this application minimizes the safety threat to personnel without affecting normal cutting operations.

[0029] The work platform has four support columns at its four corners for support. The support columns can be cylindrical, rectangular, or other shapes.

[0030] On one side, each of the two support columns 4 has a caster wheel 5 behind it, while on the other side, a pull rod 6 is located in front of the two support columns 4. The bottoms of the two caster wheels are flush with the bottoms of the four support columns. Normally, the four support columns are on the ground, providing effective support for the work platform. When the work platform needs to be moved, one side of the work platform can be slightly lifted by holding the pull rod, thereby lifting the four support columns off the ground. At this time, the work platform is mainly supported by the caster wheels. Then, by pulling the work platform, the rotation of the caster wheels easily moves the work platform to the target position. If caster wheels were installed under all the support columns 4, even if the caster wheels had a braking function, a malfunction in the braking function would easily cause the work platform to move. If the braking failure occurs when a branch is cut, it is very easy to cause a safety accident. Therefore, this application only installs caster wheels on one side, which effectively reduces safety risks while facilitating movement.

[0031] Preferably, an L-shaped connecting plate is provided between each of the two adjacent support columns. The L-shaped connecting plate not only strengthens the support function of the support column, but also allows for the placement of a storage plate, which can be used for temporary storage, thereby improving the application performance of the device.

[0032] Preferably, reinforcing ribs 9 are provided between the tie rod 6 and the two adjacent support columns 4 to strengthen the connection.

[0033] Preferably, the working platform 1 is divided into a working area and an extension area. Each side of the extension area is equipped with a baffle 11 to effectively prevent cutting debris from falling outside the working platform. The working area has extension plates 12 that slope slightly upwards from the inside out on both sides. These slightly upward-sloping extension plates 12 not only prevent cutting debris from falling, but also do not obstruct the forward movement of long branches (length greater than the width of the working platform) when the branch to be cut is long.

[0034] Preferably, the drive device 2 is a motor, and a reducer is provided between the motor and the circular saw to effectively control the speed of the circular saw and prevent it from running too fast and causing a safety threat.

[0035] Preferably, the drive unit includes a control module for controlling the circular saw's rotation speed and working time. The control module can employ conventional technology and is capable of precisely controlling the circular saw's rotation speed and working time. More preferably, the control module can preset the circular saw's continuous working time, such as 5 seconds (this time is sufficient to cut the branch). When the circular saw reaches the preset time, it immediately stops, further improving the circular saw's safety. Furthermore, the control module can be set to allow the circular saw to operate in an intermittent mode, such as working for 5 seconds and stopping for 5 seconds. During the working time, branches can be cut; during the stopping time, materials can be prepared for the next cutting operation. This avoids frequent starting and stopping of the operating switch and reduces safety hazards caused by continuous operation of the circular saw.

[0036] Preferably, the circular saw 3 is equipped with a pressure sensor, which is electrically connected to the control module. The pressure sensor can be located at the connection between the circular saw and the output shaft of the motor, etc., to detect the pressure value borne by the circular saw. When a branch comes into contact with the circular saw, it exerts a certain pressure on the circular saw. After the pressure sensor collects the pressure value, it transmits it to the control module in a timely manner. Then, the control module controls the circular saw to start cutting the branch, further improving safety.

[0037] In summary, the cutting device for flat-cutting tree branches provided in this application is simple to operate, saves time and labor, and greatly improves the efficiency of branch cutting. Moreover, it has a simple structure, is easy to move, and has good practicality and safety, making it suitable for farmers and small-scale planting.
