Description

Technical Field

[0001] The present invention belongs to the field of agricultural and forestry machinery and relates to a fire prevention and ecological protection opening machine. Background Art

[0002] Forest fire prevention is related to forest resources, ecological security, and the property safety of the people. Forest fires are characterized by large scale, fierce fire, strong heat, and long duration. If no artificial intervention is carried out in time, more serious consequences will occur. Traditional fire extinguishing methods include opening fire breaks and aircraft fire extinguishing. However, aircraft fire extinguishing is costly. Therefore, it is particularly important to simply and efficiently open fire breaks in areas that have not caught fire. The traditional method of opening fire breaks usually involves manual excavation and excavator construction. This method not only has low opening efficiency but also great difficulty in opening on mountains. Although existing fire break opening machines can improve the opening efficiency to a certain extent, when facing complex terrains with rocks, their opening effect is not ideal, the crushing effect is poor, the mobility is poor, the head of the opening machine is inconvenient to disassemble, and the adaptability is poor. Therefore, it is of great significance to develop a vehicle-mounted fire break opening machine with high mobility, high efficiency, good ground adaptability, strong crushing ability, fast installation, and simple operation. Summary of the Invention

[0003] Aiming at the above problems, the present invention aims to provide a vehicle-mounted fire break opening machine, which has the characteristics of high mobility, high efficiency, good ground adaptability, strong crushing ability, quick disassembly, and simple operation, so as to greatly improve the working efficiency of the vehicle-mounted fire break opening machine.

[0004] The present invention solves the above problems through the following technical means:

[0005] A vehicle-mounted fire break opening machine, characterized in that it includes a mounting frame, a main arm, a quick-release mechanism, a slewing bearing, a head of the opening machine, a collision-proof frame, a pitching oil cylinder, and a flipping oil cylinder. The mounting frame includes 5 mounting seats, among which the right mounting seat of the boom and the left mounting seat of the boom are symmetric left and right, the right mounting seat of the pitching oil cylinder and the left mounting seat of the pitching oil cylinder are symmetric left and right, and the mounting seat of the flipping oil cylinder is installed in the middle of the opening machine in the left-right direction. The mounting seats are installed at the front end of the vehicle through bolts. The main arm includes a right main arm and a left main arm that are symmetrically distributed left and right. The main arm is connected to the mounting frame and the quick-release device through pin shafts. The outer ring of the slewing bearing is fixedly connected to the quick-release mechanism, and the inner ring of the slewing bearing is fixedly connected to the head of the opening machine. The head of the opening machine includes a frame, a cutter barrel, a movable protective cover, a hydraulic motor, a pulley mechanism, an adjustable baffle, an oil cylinder, and a chain.

[0006] Further, the quick-release mechanism includes a quick-release pin, a spring, a wedge, a cylindrical pin, a movable member, and a fixed member. The longitudinal dimension a of the quick-release mechanism is between 150 mm and 170 mm, preferably 160 mm. The longitudinal distance between the left side of the inclined plate and the left side of the lower flat plate on the fixed member is b, and b / a is between 0.35 and 0.5, preferably 0.43.

[0007] Further, the slewing bearing includes a slewing bearing outer ring mounting plate, a slewing bearing outer ring, a slewing bearing inner ring mounting plate, a slewing bearing inner ring, a buffer spring, and a limit bolt. The opening head is fixedly connected to the inner ring of the slewing bearing and can rotate with the inner ring of the slewing bearing. A buffer spring is installed between the inner and outer ring mounting plates to damp and buffer the relative rotational movement of the inner and outer rings. A limit groove is provided on the inner ring mounting plate, and the limit bolt passes through the limit groove and is connected to the slewing bearing outer ring.

[0008] Further, the cutter drum includes a cutter and a drum. The width L of the drum is between 2.4 m and 2.6 m, preferably 2.5 m. The outer diameter of the drum is d, and the ratio d / L is between 0.1 and 0.15, preferably 0.116. The cutter of the cutter drum is arranged on the drum in a spiral form.

[0009] Further, the adjustable baffle is installed at the lower part of the frame by bolts. There are three pairs of mounting holes on it. By adjusting the mounting position of the bolts, the relative position between it and the cutter drum can be adjusted.

[0010] Further, the anti-collision frame includes an L-shaped ear plate, a square hollow steel, a support rod, and a serrated plate. The serrated plate is welded to the upper end of the anti-collision frame and is used to bend the front target object and prevent the target from slipping when the opening head is working. By adjusting the mounting position of the lower end of the support rod on the vertical plate of the frame, the pitching angle of the anti-collision frame can be adjusted.

[0011] Further, during normal operation, the lower surface of the adjustable baffle is flush with the ground. The opening head is controlled by a pitching oil cylinder connected to the main arm to lift and lower the opening head, and is controlled by a tilting oil cylinder connected to the mounting frame to perform the up and down tilting movement of the opening head.

[0012] Compared with the existing invention, the beneficial effects of the present invention are:

[0013] (1) The opening width is between 2.4 m and 2.6 m, featuring a large opening width;

[0014] (2) Under the combined action of the pin, wedge, and spring of the quick-release mechanism, the quick disassembly and assembly between the opening head and the vehicle can be conveniently achieved;

[0015] (3) The slewing device can achieve the left and right slewing motion of the cutting head, so as to produce adaptive swinging with respect to the terrain. A slewing spring is designed on the slewing device to buffer the slewing motion, and a limiting groove is designed on the slewing device to avoid excessive slewing motion;

[0016] (4) The ratio of the drum width to the diameter d / L of the cutter barrel is between 0.1 and 0.15, so that the cutter barrel has good rigidity and dynamic balance characteristics. The cutting tools are arranged on the drum in a spiral form, which increases the crushing ability of the cutting head to a certain extent. Description of the Drawings
