Description

Technical Field

[0001] This utility model relates to a device for cutting wood into segments, belonging to the technical field of wood segmentation devices. Background Technology

[0002] In the processing and utilization of wood materials, such as branches and logs, it is usually necessary to cut wood biomass into segments. Cutting equipment is an essential device. In the cutting device, the cutting blade is an important core structure. People in the art have been researching how to design a blade suitable for cutting wood, which can not only meet the requirements of wood cutting, but also improve the service life of the blade and make the cut surface of the wood smoother. Utility Model Content

[0003] To improve wood cutting efficiency, create smoother cuts, and provide better protection, this invention provides a wood cutting device. Improvements to the wood cutting blade enhance cutting effectiveness and extend blade life; additionally, a protective mechanism is added to the feed inlet to ensure safety during use.

[0004] This utility model solves the above-mentioned technical problems through the following technical solution: A device for cutting wood into segments includes a housing with an inlet and an outlet on opposite side walls. A pair of cutting blades are mounted vertically inside the housing, driven by a drive unit mounted on the outside of the housing. The device is characterized in that each cutting blade includes a blade shaft, a blade mounting sleeve fixedly fitted onto the blade shaft, and multiple fixedly mounted blades. Each blade includes a mounting tail, a first cutting edge, a second cutting edge, a third cutting edge, and a fourth cutting edge. The second cutting edge and the first cutting edge form a cutting edge, with an acute angle α between them. The first cutting edge and the third cutting edge form an acute angle β, with the third cutting edge extending from the mounting tail. The fourth cutting edge connects to the third cutting edge, with an obtuse angle between them, and the fourth cutting edge is parallel to the first cutting edge.

[0005] The advantages of the above technical solution are as follows: In practice, the inventors discovered that commonly used cutting tools are mostly wedge-shaped, with only one inclined surface on the cutting edge. When cutting wood, the wood is broken by the bottom of the cutting edge. Such tools result in uneven cut surfaces and, because the wood is broken by the tool, the wood also exerts a reaction force on the tool, causing wear and tear. Based on this discovery, the inventors improved the cutting edge of the tool, designing a two-section design as in this application. The second and third cutting edges form different angles with the first cutting edge. While ensuring the strength of the cutting section (the inclined surface has a certain thickness), the force exerted by the tool on the wood is reduced as the tool cuts into the wood. The cutting edge continues to cut the wood until the upper and lower edges contact and cut the wood completely.

[0006] Based on the above technical solution, this application makes the following improvements and enhancements to the above technical solution: Furthermore, there are two, three, or four blades, evenly arranged on the blade mounting sleeve.

[0007] The beneficial effects of the above-mentioned technical features in this application are: the above structure is designed to achieve continuous cutting of wood during the rotation of the cutter shaft; at the same time, it enables continuous and automatic feeding of wood during the rotation of the cutter shaft.

[0008] Furthermore, a feed hopper is installed at the feed inlet; a folding trough is installed at the inlet end of the feed hopper via a shaft connection.

[0009] The beneficial effects of the above-mentioned technical features in this application are: by installing a folded feed trough, firstly, the length of the feed end is increased, reducing the chance of workers coming into contact with the blade and improving safety performance; secondly, the load-bearing capacity of the feed trough end is increased, reducing the labor intensity of workers.

[0010] Furthermore, the folding trough includes a trough body, a protective pressure rod is installed at the feeding end of the trough body, the protective pressure rod surrounds the trough opening of the trough body, and a protective switch is installed on one side wall of the trough body; an L-shaped fixing plate is also installed on the side wall of the trough body, and a through hole is provided on the plate arm where the L-shaped fixing plate collides with the protective pressure rod; a touch plate is fixedly installed on the protective pressure rod at the contact point with the protective switch, a limiting screw is installed in the middle of the touch plate, a through hole rod is installed at the end of the touch plate, a reset spring is fitted on the through hole rod, and a nut is installed at the end of the through hole rod.

[0011] The beneficial effects of the above-mentioned technical features in this application are as follows: the above design is mainly for safety; when workers operate the equipment, their clothes may get caught and pulled toward the blade for some reason. At this time, the protective pressure bar can be pressed in an emergency. The protective pressure bar is surrounded by the material trough, and workers can press it from any angle to activate the protective switch, thereby braking the equipment in an emergency and stopping its operation, thus improving the safety of the equipment.

[0012] Furthermore, the drive box includes a drive housing, inside which two interlocking large gears are arranged vertically, each large gear being mounted at the end of a cutter shaft; the lower large gear meshes with a driven small gear, the driven small gear and the driven large gear are coaxially fixedly installed, and the driven large gear meshes with the driving small gear.

[0013] The beneficial effects of the above-mentioned technical features in this application are: the gear transmission can improve the frequency of the tools on the upper and lower tool shafts, and the tool runs stably during rotation and cutting; the two-stage reduction can increase the torque, that is, increase the cutting force of the tool.

[0014] Furthermore, the drive box also includes a friction clutch universal joint that is connected to the rear axle drive shaft of the tractor.

[0015] The beneficial effects of the above-mentioned technical features in this application are: the above structure is suitable for use with a diesel engine, the diesel engine speed is relatively slow, and the power can be transmitted between the connecting rods to meet the use of the equipment.

[0016] Furthermore, the drive box also includes a large pulley, which is coaxially and fixedly installed with the drive pinion. The large pulley is connected to the small pulley via a belt, and the small pulley is fixedly installed on the output shaft of the gasoline engine.

[0017] The beneficial effects of the above-mentioned technical features in this application are: the above structure is applicable to gasoline engines, which have a relatively high output speed. By driving a large pulley with a small belt, the transmission speed can be reduced.

[0018] Furthermore, it also includes the discharge port conveyor belt.

[0019] The beneficial effects of the above-mentioned technical features in this application are: the discharge conveyor belt is used to transport the cut wood segments to the loading device, and the conveyor belt is provided with dividing vertical plates, so that each cut wood is between two adjacent dividing vertical plates; thus solving the problem of wood slippage.

[0020] This application has the following advantages: 1. By improving the cutting edge of the tool, the blade always cuts the wood during the cutting process, resulting in a smooth cut surface. At the same time, the strength of the tool is guaranteed, and the service life of the tool is extended. 2. By designing a system with two transmissions, different drive methods can be provided according to customer needs; 3. Improve safety during operation by designing a protective structure at the feed end. Attached Figure Description
