Description

Technical Field

[0001] This utility model relates to the field of grassland fire-fighting engine technology, specifically a grassland fire-fighting engine with a fire-grinding plate. Background Technology

[0002] Grassland fires are a common and destructive natural disaster that often spreads rapidly, burning large areas of grassland and vegetation and threatening the lives and property of local herders as well as the habitat of wild animals.

[0003] Currently, grassland fires are generally extinguished manually, typically by carrying wind-powered fire extinguishers on their shoulders or using shovels and brooms to beat the fire. However, this method often suffers from drawbacks such as low extinguishing efficiency, high labor intensity, and the risk of burns to personnel due to strong winds and complex fire conditions.

[0004] As disclosed in Chinese Patent CN214435966U, a grassland fire suppression vehicle with a fire suppression device includes a fire suppression vehicle body, with a fire suppression device located at the rear of the vehicle body. The fire suppression device includes a rotating roller, a rotating roller support, and a fire suppression blanket. Rotating roller supports are located at both ends of the rotating roller. The rotating roller is horizontally rotatable at the rear of the fire suppression vehicle body via the rotating roller supports. A fire suppression blanket is wrapped around the rotating roller. The fire suppression blanket is composed of one or more fire suppression plates spliced ​​together by chains, with one side of each plate fixedly connected to the chain. The advantages are that the fire suppression vehicle body is an all-terrain vehicle with remote control functionality, making it easy to operate, highly maneuverable, and adaptable. It can meet the needs of both manned and unmanned operation in dangerous firefighting environments. The fire suppression device at the rear of the vehicle body extinguishes open flames by dragging and pressing, improving the thoroughness and efficiency of firefighting. The overall fire extinguishing method is physical, causing no pollution to the burned grassland and not damaging the root system of the regenerating pasture.

[0005] However, the fire suppression device is composed of multiple fire suppression plates. After prolonged use, these plates may become damaged and fall off, affecting the performance and reducing work efficiency.

[0006] To address this problem, we propose a grassland fire engine with a fire-grinding plate. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This grassland fire extinguishing vehicle equipped with a fire-grinding plate, through the fire-grinding mechanism, activates a drive motor to rotate a first movable rod when the vehicle body passes over ground compacted by a compaction roller. Since a limit rod is installed on the surface of the first movable rod, and this limit rod is installed inside the sliding groove of a second movable rod, the rotation of the first movable rod, via the limit rod, causes the second movable rod to rotate on the surface of a fixed plate. Through a pressing plate installed on the side of the second movable rod, the pressing plate reciprocates and presses against the fire-grinding plate as the second movable rod moves. The fire-grinding plate, through the action of the fixed rod and spring, reciprocates and pounds the ground, thus achieving the fire-extinguishing effect.

[0017] 2. This grassland fire engine equipped with a fire-grinding plate uses a compaction mechanism. By activating a telescopic cylinder, the mounting plate is lowered, causing the compaction roller to contact the ground and compact any protruding objects on the ground. This prevents the fire-grinding plate from becoming uneven due to impacts during operation, which would affect the fire-grinding effect. Attached Figure Description

[0029] Example 3: Based on Example 1, the compaction mechanism includes a second mounting slot 301, a telescopic cylinder 302, a mounting plate 303, a compaction roller 304, and a sealing plate 305. The second mounting slot 301 is opened on the front surface of the vehicle body 101. The telescopic cylinder 302 is fixedly installed on the inner wall of the second mounting slot 301. The mounting plate 303 is connected to the output end of the telescopic cylinder 302. The compaction roller 304 is rotatably installed on the surface of the mounting plate 303 to compact objects protruding on the ground, preventing the surface of the fire-rolling plate 201 from being bumped and uneven during operation, which would affect the fire-rolling effect. The sealing plate 305 is installed at the opening of the second mounting slot 301.

[0030] Working principle: During use, the telescopic cylinder 302 is activated, causing the mounting plate 303 to descend, making the compaction roller 304 contact the ground and compact any protruding objects on the ground. This prevents the surface of the fire-grinding plate 201 from becoming uneven due to impacts during operation, which would affect the fire-grinding effect. When the vehicle body 101 passes over the ground compacted by the compaction roller 304, the drive motor 207 is activated, causing the first movable rod 208 to rotate. Since a limit rod 209 is installed on the surface of the first movable rod 208, and the limit rod 209 is installed inside the sliding groove 211 of the second movable rod 210, the first movable rod 208, when rotating, drives the second movable rod 210 through the limit rod 209. The rotation of the first movable rod 210 on the surface of the fixed plate 213 causes the pressing plate 212 installed on the side of the second movable rod 210 to reciprocate and press the fire-grinding plate 201. The fire-grinding plate 201, through the action of the fixed rod 203 and the spring 205, reciprocates and strikes the ground, thereby achieving the fire-extinguishing effect. At the same time as the vehicle body 101 moves, the water pump 404 is started to draw water from the water tank 401 and deliver it to the annular water jet 406 through the water pipe 405. The water is then sprayed out by the atomizing nozzle 408 on the annular water jet 406 to extinguish the fire.
