Description

Double-chain type forest clearing and cutting mechanism

The technical field is as follows:

the utility model belongs to the technical field of forestry machinery and specifically relates to a be applied to chain cutting device of quick clearance in woodland.

Background art:

the clearing of forest and cutting of shrubs are important links for tending forest trees. The forest clearing and cutting is a necessary process for ensuring the sustainable development of forestry by cutting off weed shrubs which influence the growth of reserved trees to ensure the growth of young forests. With the growth of forestry production in China, the harvest quantity is increasing day by day, and the task of clearing forest is increased. The traditional manual forest cleaning method (such as sickle, chain saw, manpower backpack brush cutter, etc.) has high working strength, poor working environment, needs to consume a large amount of manpower resources, and is not suitable for the current situation of serious shortage of the labor force in China. Utilize the vehicle to carry on high-efficient cutting device can compensate the shortcoming that the mobility is not enough in the woodland environment of workman, guarantees operation personnel's safety simultaneously, improves the operation comfort level. The mechanized forest cleaning and cutting can improve the operation efficiency, increase the operation area, greatly reduce the demand of forest land cleaning on operating personnel, and liberate the labor force. Mechanized forest cleaning becomes the inevitable direction for the efficient and continuous development of forestry in China.

This novel cutting device mainly used solves the problem that artifical woodland clearance inefficiency through carrying on middle-size and small-size motor vehicle, improves clear forest work mobility, improves clear forest cutting efficiency through both sides chain cutting mechanism symmetrical arrangement, and both sides saw chain reverse motion realizes the cutting back bush and emptys the controllable of direction, and the frame improves cutting mechanism's stability, security.

The utility model has the following contents:

an object of the utility model is to the above-mentioned problem, provide a but high efficiency, stable in structure safety, clear forest cutting device that the carryability is strong.

The utility model provides a technical scheme is:

the utility model provides a be applied to novel chain cutting mechanism of woodland clearance, includes frame, hydraulic motor, drive mechanism, wherein includes shaft coupling, transmission shaft, cutting mechanism, wherein includes driving sprocket, baffle and saw chain. The hydraulic motor is fixed on the motor support, and the motor support is fixed on the frame. One end of the coupler is connected with an output shaft of the hydraulic motor, and the other end of the coupler is connected with a transmission shaft connected with the driving chain wheel. The driving chain wheel drives the saw chain to cut.

The attached drawings of the specification:

figure 1 is a three-dimensional structure diagram of the embodiment of the utility model

FIG. 2 is a front view of the embodiment of the present invention

FIG. 3 is a left side view of the embodiment of the present invention

FIG. 4 is a top view of the embodiment of the present invention

The specific implementation mode is as follows: the frame 1 is articulated with the boom of the forestry vehicle. The hydraulic motor 2 is fixed on the motor support 3, and the motor support 3 is fixed on the frame 1. The output shaft of hydraulic motor 2 is connected on shaft coupling 4, and the transmission shaft that is connected with drive sprocket 5 is connected to the 4 other ends of shaft coupling, and drive sprocket will drive the saw chain and cut. The saw chain moves around a guide plate 6, which guide plate 6 is fixed to the frame 1. The power of the whole transmission mechanism is from a hydraulic motor, and is directly output to a driving chain wheel through a coupler and a transmission shaft to drive a saw chain to move for cutting.

The utility model discloses further set up to: two groups of same equipment, including a hydraulic motor, a transmission system, a saw chain and the like, are fixed on the frame in a symmetrical arrangement mode.

The utility model discloses further set up to: the saw chain on two sides is fixed in the frame through the baffle, guarantees stable in structure, increases structural strength. The two saw chains form a triangular cutting range, and the middle parts of the saw chains and the saw plates are firstly contacted with an object to be cut. When cutting operation is carried out, the shrubs can also fall down to the two sides under the action of force, and the shrubs can be continuously cut by the saw chain in the process, so that the cutting success rate of the shrubs is greatly increased, and the overall cutting efficiency is improved.

The utility model discloses further set up to: the cutting directions of the saw chains on the two sides are opposite (the left side saw chain moves anticlockwise and the right side saw chain moves clockwise from the perspective of a driver of the vehicle), and the cutting directions are favorable for controlling lodging of the cut shrubs, so that the cut shrubs are lodged towards the two sides of the vehicle and are concentrated on the two sides of the driving track of the vehicle, and subsequent collection and cleaning are facilitated.

The utility model relates to a be applied to the bush cutting of woodland clearance. The device has strong carrying performance and is suitable for various medium and small vehicles. The utility model discloses utilize vehicle self hydraulic energy drive hydraulic motor output power, reduced the use of motor, accord with energy saving and emission reduction's green theory. The use of a speed reducer and other transmission structures is reduced by utilizing the transmission of the coupler, so that the whole structure is simple to install, the durability is improved, and the operation is safe. The saw chains on two sides and the frame form a triangular cutting range, and the cutting efficiency is improved. Through the utility model discloses can improve the operating efficiency that the clear forest cut and irritate.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
