Description

Technical Field

[0001] The utility model relates to an isolation belt opening device, belonging to the technical field of garden emergency rescue mechanical equipment. Background Art

[0002] With the continuous increase of human activities, the health of forests is deteriorating, the incidence of forest fires is increasing, and the disaster area is also expanding. Due to the inconvenient transportation in forests and the flammable plants, limited manpower and material resources are often unable to completely control the spread of fires. Opening fire isolation belts is the safest and most reliable measure to eliminate forest fires.

[0003] At present, the isolation belt development equipment produced domestically have all evolved from pioneer machines, which are highly applicable to shrubs and grass. However, when faced with forests with intertwined roots on the surface and a humus layer as thick as 300mm, the above-mentioned equipment has the problems of weak power, inability to efficiently cut the intertwined and adhered strata of tree roots, low operating depth, and inability to completely remove the humus layer, which seriously affects the efficiency of fire rescue and causes great disaster losses.

[0004] As described in patent CN201720254532.7, a fireproof belt-cutting machine is disclosed. It has no autonomous cutting power and relies on the chassis's own movement to drive the belt-cutting disk to rotate. The rotation speed is low and it cannot effectively cut off tree roots. In addition, the equipment has no shoveling function and uses the belt-cutting disk to turn the raw soil out of the ground to block the fire. However, in areas with thicker humus layers, the thickness of the accumulated burning materials can reach more than 300 mm. The equipment can only break up the humus layer and cannot effectively remove it, and cannot play the role of blocking and extinguishing the fire. Utility Model Content

[0005] In order to solve the shortcomings of the prior art, the purpose of the utility model is to provide an isolation belt development equipment, which solves the problems of the isolation belt development equipment in the prior art being weak in power, unable to efficiently cut the strata where tree roots are staggered and adhered, having a low operating depth, and unable to completely remove the humus layer.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A device for opening up isolation belts, including a cutting mechanism, a bulldozer, an operator's cab, a crawler chassis, and a power and auxiliary system.

The rotating mechanism on one side of the frame is connected to the left cutting saw through a hydraulic motor, and the rotating mechanism on the other side of the frame is connected to the right cutting saw through a hydraulic motor. One end of the crank arm cylinder is connected to the crawler chassis, and the other end of the crank arm cylinder is connected to the crank arm.

[0010] Furthermore, the aforementioned also includes a bracket, and the lower parts of the sides of the left cutting saw and the right cutting saw are connected with the bracket, and the bracket is coaxially arranged with the left cutting saw and the right cutting saw.

[0011] Furthermore, the aforementioned also includes a bulldozer, which is hinged to the front end of the crawler chassis through a rocker arm, and the bulldozer is located at the rear side of the cutting mechanism.

[0012] Furthermore, the aforementioned also includes a rocker arm cylinder, one end of the rocker arm cylinder is connected to the crawler chassis, and the other end of the rocker arm cylinder is connected to the rocker arm.

[0013] Furthermore, the working cross-section of the bulldozer is an Archimedean spiral arc structure.

[0014] Furthermore, a crawler walking device is connected to the bottom end of the crawler chassis.

[0015] Furthermore, the left cutting saw and the right cutting saw can be rotated 90 degrees downward around the rotating mechanism.

[0024] This embodiment discloses a device for opening up an isolation zone. Figure 1 As shown, it includes a cutting mechanism 1, a bulldozer 2, a control room 3, a crawler chassis 4, and a power and auxiliary system 5. The control room 3 and the power and auxiliary system 5 are arranged on the crawler chassis 4, the cutting mechanism 1 and the bulldozer 2 are connected to the front end of the crawler chassis 4, and a crawler travel device is installed at the bottom of the crawler chassis. The operator operates the entire equipment in the control room 3, and the power and auxiliary system 5 provides power and control for the entire vehicle. The crawler travel device drives the entire equipment forward, backward or turns, and drives the cutting mechanism 1 and the bulldozer 2 to continuously move forward.

[0025] The cutting mechanism 1 is hinged to the crawler chassis 4 through the crank arm 18. One end of the crank arm cylinder 19 is connected to the crawler chassis 4, and the other end is connected to the crank arm 18 to adjust the cutting depth and position of the cutting mechanism 1. The cutting depth of the cutting mechanism 1 is ≥300mm, which can quickly cut off the middle humus layer from both sides. Figure 2 As shown, the cutting mechanism includes a left cutting saw 11, a left protective cover 12, a rotating mechanism 13, a frame 14, a right protective cover 15, a right cutting saw 16 and a bracket 17.
