Technical Field

[0001] This invention belongs to the technical field of forest fire prevention equipment, specifically a forest firebreak opening device. Background Technology

[0002] Currently, forest fires often consume excessive human and material resources annually, and conventional firefighting equipment is unable to sustain firefighting efforts in complex terrain, leading to severe and uncontrollable fires that negatively impact forest resource development. Firefighting in my country still relies primarily on manual labor, supplemented by large machinery. Firefighters experience rapid physical exhaustion, and for extremely large fires, the only option is to create firebreaks. Traditional firebreak-creating vehicles work by disrupting the ground to prevent fire spread; however, in mountainous forests with complex terrain and surrounding trees that can also spread the fire, firebreaks are less than effective. Furthermore, the equipment is prone to getting stuck in the soil during firebreak creation, making it unsuitable for various geological environments.

[0041] Please see Figure 1 In this embodiment of the invention, a forest firebreak opening device includes:

[0042] The outer frame 1 has drive wheels symmetrically arranged on both sides for driving and guiding;

[0043] The intermediate shaft 11 is laterally arranged within the outer frame 1, which can rotate relative to it.

[0044] An external motor 12 is fixed on the outer frame 1, and the output end of the external motor 12 is connected to the intermediate shaft 11 for transmission via a transmission chain belt;

[0045] The soil turning and strip opening device 2 consists of multiple devices arranged in a row, and each of the soil turning and strip opening devices 2 is fixed on the intermediate shaft 11.

[0046] The spray pipe 13 is horizontally suspended on one side of the outer frame 1; and

[0047] The diffusion nozzle 14 is vertically installed on the spray pipe 13. That is to say, the spray pipe can spray the agent first, and then the soil turning and opening device can turn the soil to realize the opening of the fireproof isolation belt.

[0048] In this embodiment, the soil-turning and strip-opening device 2 includes:

[0049] A fixed plate frame 21 is sleeved and fixed outside the intermediate shaft 11, and multiple columns 22 are distributed circumferentially on the fixed plate frame 21.

[0050] The cutting frame 23 is configured in an L-shape, and one end of the cutting frame 23 is connected to each of the column frames 22;

[0051] Vibrating rod assembly 4 is connected between the cutting frame 23 and the column frame 22, and the output end of the vibrating rod assembly 4 is fixed to the column frame 22; and

[0052] The spraying frame device 3 is located at the end of the turning frame 23. The intermediate shaft 11 is a hollow structure and has a liquid supply pipe inside. The liquid supply pipe is connected to the spraying frame device 3 through multiple branch pipes. In particular, the spraying frame device can also mix the agent during the turning process, which can absolutely isolate the growth of weeds.

[0053] In a preferred embodiment, the vibrating rod assembly 4 includes:

[0054] The outer shaft tube 41 is sleeved and fixed to the lower 22 of the column frame;

[0055] Rotating sleeve 42 is rotatably disposed inside the outer shaft tube 41;

[0056] The inner column 43 is vertically slidably disposed in the outer shaft tube 41, and the lower end of the inner column 43 is bolted to the cutting frame 23;

[0057] An oscillator (not shown in the figure) is embedded in the column frame 22, and the output end of the oscillator is fixed to the inner column 43 by a section rod 44; the oscillator is capable of high-frequency vertical vibration output;

[0058] A rubber ring 45 is disposed at the lower end of the outer shaft tube 41 and is sleeved with the cutting frame 23;

[0059] A forming cavity tube 46 is coaxially disposed inside the outer shaft tube 41, and the upper end of the forming cavity tube 46 is fixed to the rotating sleeve 42; and

[0060] Side guide balls 47 are circumferentially distributed on the inner connecting column 43. The side guide balls 47 are connected to the inner connecting column 43 through an inner spring. In other words, the oscillator can drive the turning frame to vibrate at high frequency through the link rod, so as to facilitate timely release when the soil turns and gets stuck.

[0061] In this embodiment, the inner wall of the forming cavity tube 46 is configured as an eccentric spherical structure, and an elastic ring 48 is provided between the inner connecting column 43 and the rotating sleeve 42. A micro motor is provided outside the outer shaft tube 41, and the output end of the micro motor is connected to the rotating sleeve 42 for transmission through gear meshing. In particular, when the inner connecting column vibrates vertically at high frequency, the side guide ball can drive the inner connecting column to slide radially along the inner side wall of the forming cavity tube. The rotating sleeve can realize the rotation adjustment of the forming cavity tube, thereby adjusting the flipping frame on the same fixed plate to vibrate to different degrees.

[0062] In this embodiment, the spraying frame device 3 includes:

[0063] The cutting plate 31 is rotatably connected to the flipping and cutting frame 23;

[0064] An inner liquid cylinder 32 is embedded and fixed inside the flipping frame 23, and a connecting plug 33 is slidably arranged in the inner liquid cylinder 32;

[0065] A support spring is fitted onto the outside of connector 33;

[0066] The transmission rod 34 is hinged to the connector 33, and one end of the transmission rod 34 is connected to the cutting plate 31;

[0067] The first liquid hole is located on one side of the inner liquid cylinder, and an outer pipe 35 is connected to the first liquid hole;

[0068] A fixed spray nozzle 36 is embedded in the cutting plate 31, and the outer pipe 35 is connected to the fixed spray nozzle 36 to allow for secondary mixing and spraying of the agent.

[0069] In this embodiment, a second liquid hole is provided on one side of the inner liquid cylinder 32, and a compression spring is sleeved on the plug 33 inside the inner liquid cylinder 32. The second liquid hole is connected to the fixed spray member 36 through the inner pipe 37.

[0070] In a preferred embodiment, the liquid flow pressure in the inner liquid cylinder 32 is in the range of 0.25 MPa to 0.3 MPa, so that the connecting plug 33 can always pass the first liquid hole. At the same time, when the connecting plug 33 passes the second liquid hole, the compression spring can push the connecting plug 33 to reset its displacement under the action of elastic force. That is to say, when the drug delivery pressure in the inner liquid cylinder is in the range of 0.25 MPa to 0.3 MPa (e.g., 0.26 MPa), the connecting plug slides past the first liquid hole under the action of pressure, which can perform constant pressure liquid supply. When it passes the second liquid hole, the internal pressure of the inner liquid cylinder is insufficient, so the compression spring drives the connecting plug to slide back to between the first liquid hole and the second liquid hole under the action of elastic force, thereby forming a pulse-type pressurized injection, and driving the cutting plate to swing at different frequencies, resulting in a low rate of soil entrapment.

[0071] Specifically, the drive wheel drives the main body of the forest land to turn over the soil in order to form a firebreak. In this process, the diffusion nozzles can mix the pesticide to prevent weeds from growing back. At the same time, the spray frame device can fully mix the pesticide. In particular, the various turning frames on the spray frame device have multiple ways to adjust the vibration to avoid being trapped by the soil and to adapt to different forest geology.

[0072] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
