Description

Technical Field

[0001] This invention relates to the field of logging cutter arm technology, specifically a logging cutter arm structure for logging engineering vehicles. Background Technology

[0002] Many types of machinery are used in logging operations, including logging vehicles. These vehicles can cut timber from the bottom, cutting it into equal lengths. They can also be used for aerial logging operations in urban areas. Existing logging vehicles use a robotic arm controlled by a clamp to hold the trunk in place, then pushes the saw blade towards the trunk to cut it and obtain timber. However, this type of logging arm is only suitable for thinner trunks. For trunks with a diameter greater than 1 meter, the saw blade is too large, requiring a radius exceeding 1 meter, necessitating a larger device to push the blade. Furthermore, existing clamps cannot be adjusted in size, making it impossible to fully close and secure larger diameter trunks. Therefore, those skilled in the art have provided a logging arm structure for logging vehicles to address the problems mentioned in the background section. Summary of the Invention

[0003] The purpose of this invention is to provide a logging cutter arm structure for logging engineering vehicles to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A logging arm structure for a logging engineering vehicle includes a connecting block. One end of the connecting block is fixedly connected to a clamping frame. The surface of the clamping frame is provided with clamping components. A third servo motor is fixedly installed at the bottom of the clamping frame. The drive end of the third servo motor faces downward and is fixedly connected to an electric saw. A saw chain is installed on one side of the electric saw. A direction control component is installed at the other end of the connecting block.

[0005] As a further embodiment of the present invention: the clamping assembly is provided in two sets, located on the upper and lower sides of the clamping frame respectively. Each set of clamping assemblies includes two sixth servo motors located on the same horizontal plane. The sixth servo motors are fixedly installed on the front side of the clamping frame, and a clamping arm is fixedly connected to the drive end of the sixth servo motor. The two clamping arms in the same set are bent towards the other side.

[0006] As a further embodiment of the present invention: a fifth servo motor is fixedly installed at the end of the clamping arm away from the sixth servo motor, and an extension arm is fixedly connected to the driving end of the fifth servo motor, and an extension arm is fixedly connected to the driving end of the extension arm.

[0007] As a further embodiment of the present invention: the two clamping arms located in the same group are staggered, the two extension arms located in the same group are also staggered, and the staggered direction of the two clamping arms is opposite to the staggered direction of the two extension arms.

[0008] As a further embodiment of the present invention: a bidirectional cylinder is fixedly installed inside the clamping frame. The bidirectional cylinder is horizontally arranged. Both drive ends of the bidirectional cylinder are fixedly connected to movable brackets. A second cylinder is embedded and fixedly installed inside the movable brackets. The second cylinder is located between the two sets of clamping components. The drive end of the second cylinder is facing away from the connecting block. A motor is fixedly installed on the drive end of the second cylinder. A roller is fixedly connected to the drive end of the motor.

[0009] As a further aspect of the present invention, the outer surface of the roller is provided with anti-slip teeth.

[0010] As a further embodiment of the present invention: the direction control component includes a connecting frame, a second servo motor is fixedly mounted on the surface of the connecting frame, the drive end of the second servo motor is fixedly connected to the connecting block, a plane bearing is fixedly connected to the other end of the connecting frame, the upper plane of the plane bearing is fixedly connected to the drive end of the first cylinder, an extension plate and a driven gear are fixedly connected to the upper and lower sidewalls of the plane bearing respectively, a first servo motor is fixedly mounted on the surface of the extension plate, a drive gear is fixedly connected to the drive end of the first servo motor, and the drive gear and the driven gear mesh.

[0011] As a further embodiment of the present invention: the direction control component further includes an extension rod, one end of which is fixedly connected to a fourth servo motor, the drive end of the fourth servo motor is fixedly connected to the fixed end of the first cylinder, the other side of the extension rod is hinged to a rotating seat, the surface of the rotating seat is rotatably connected to a mounting seat, the interior of the rotating seat is hinged to a third cylinder, and the drive end of the third cylinder is hinged to the surface of the extension rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up clamping arms and extension arms, it can be applied to both large and small diameter timber, improving the versatility of the equipment. Furthermore, the clamping arms and extension arms in the same group are staggered to avoid mutual squeezing and abutment between clamping arms and extension arms when clamping and fixing timber, ensuring that the clamping state can always be fully closed. In contrast, the electric saw uses a third servo motor to control its rotation. Compared to using a saw blade for cutting, the saw chain cutting does not require a propulsion device, does not occupy a large volume, is lighter, and is more flexible to operate. It is also equipped with rollers to control the movement of timber and perform segmented cutting of timber.

[0013] 2. By setting up a direction control component, the direction of the clamping component and the chainsaw can be precisely controlled, facilitating logging operations. Attached Figure Description
