DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0028] Please refer to Figures 1-5, the utility model provides a technical solution: a device for preventing the spread of grassland fires, including a mounting plate 1, an operation box 2, traveling wheels 3, a collection box 4, an air extraction pump 5, an air supply pipe 6, a dust-proof plate 7, a feed pipe 8, a storage box 9, a first electric telescopic rod 10, a rectangular plate 11, a cleaning plate 12, a first motor 13, a lead screw 14, an air outlet plate 15, a moving plate 16, a crushing motor 17, a mowing knife 18, a second electric telescopic rod 19, a mounting frame 20, a second motor 21 and an earth-removing roller 22. When a grassland fire occurs, the staff drives the device for preventing the spread of grassland fires at a certain distance from the fire to process the grass and soil on the grassland;

[0029] As Figure 1 shown, an operation box 2 is installed above the mounting plate 1. A box door is provided at the front end of the operation box 2. The staff enters the inside of the operation box 2 through the box door. The staff operates the device for preventing the spread of grassland fires inside the operation box 2. Traveling wheels 3 are installed below the mounting plate 1, and the device for preventing the spread of grassland fires is moved through the traveling wheels 3;

[0030] The grass is mowed by a mowing mechanism. The crushing motor 17 inside the mowing mechanism drives the mowing knife 18 to rotate to cut the grass on the grassland. The first electric telescopic rod 10 drives the rectangular plate 11 to move up and down, thereby driving the mowing knife 18 to move up and down. The first motor 13 drives the lead screw 14 to rotate, and the moving plate 16 threadedly connected to the lead screw 14 moves back and forth. By using the up-and-down and back-and-forth movement of the moving plate 16, the mowing range is expanded, making the grass into shredded materials. As Figure 2 and Figure 3 shown, the left side surface of the cleaning plate 12 is in contact with the right side surface of the air outlet plate 15. When the cleaning plate 12 fixed to the left side surface of the rectangular plate 11 moves up and down, it cleans the filtering structure inside the air outlet plate 15;

[0031] When mowing the grass, the air extraction pump 5 is turned on. Under the action of the air extraction pump 5, most of the grass shredded materials enter the inside of the collection box 4 through the feed pipe 8. The forage falls into the inside of the storage box 9. The output end of the air extraction pump 5 is fixed with an air supply pipe 6. The top end of the air supply pipe 6 is connected to the operation box 2. After being filtered by the dust-proof plate 7 inside the collection box 4, the filtered air enters the inside of the operation box 2 from the air supply pipe 6, and the air then flows out from the filtering holes inside the air outlet plate 15 to keep the inside environment of the operation box 2 clean. As Figure 1 and Figure 5 shown, the bottom end of the collection box 4 is fixedly installed with a storage box 9 by screws. The screws are removed to disassemble the storage box 9, and the forage inside the storage box 9 is processed;

[0032] As Figure 1 and Figure 4As shown, while the mowing mechanism is mowing the grass, the earth-digging mechanism behind digs the soil. The earth-digging mechanism includes a second electric telescopic rod 19, a mounting frame 20, a second motor 21 and an earth-digging roller 22. Under the action of the second electric telescopic rod 19, the mounting frame 20 moves obliquely downward, so that the blades on the earth-digging roller 22 enter the soil. The second motor 21 drives the earth-digging roller 22 to rotate, and the rotation of the earth-digging roller 22 is used to cut open the soil to form an isolation belt to prevent the fire from passing through the isolation belt. The traveling wheels 3, the air extraction pump 5, the first electric telescopic rod 10, the first motor 13, the crushing motor 17, the second electric telescopic rod 19 and the second motor 21 are all prior arts and will not be elaborated here. The above completes a series of operations of the grassland fire prevention and spread prevention device. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0033] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt the mature conventional means such as bolts, rivets and welding in the prior art.
