Description

Technical Field

[0001] This utility model relates to the field of forest fire fighting equipment technology, specifically a grass-cutting device for a forest firebreak clearing robot. Background Technology

[0002] Forest fires are extremely destructive natural disasters. Once they occur, they spread rapidly, posing a huge threat to forest resources, the ecological environment, and the lives and property of nearby residents. Among the many forest fire prevention measures, creating firebreaks is an effective method. It can effectively stop the spread of fire, buy time for firefighting and rescue, and reduce the losses caused by the fire.

[0003] Currently, firebreaks are created using lawnmowers. However, due to varying terrain, there may be sand or rocks on the ground. During the use of lawnmowers, flying debris can pose a safety hazard and affect the efficiency of creating firebreaks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mowing device for a forest firebreak clearing robot, which solves the problem that flying gravel during the use of the mowing device affects the clearing efficiency of the firebreak.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mowing device for a forest firebreak clearing robot includes a device housing, a support roller rotatably mounted on the device housing, multiple sets of blades fixedly mounted on the support roller, two sets of fixing plates fixedly mounted on the device housing, and a baffle rotatably mounted on the device housing.

[0007] The device is equipped with a protective device to prevent flying debris;

[0008] The baffle is equipped with a cleaning device for cleaning it;

[0009] The device housing is equipped with a drive unit. By activating the protective device, the baffle rotates and drives the cleaning device to rotate. As the drive unit is activated, the cleaning device moves on the baffle.

[0010] Preferably, the protective device includes an electric telescopic rod fixedly installed on the device housing, a connecting plate fixedly installed on the electric telescopic rod, a toothed plate fixedly installed on the connecting plate, and an adjusting gear meshing with the toothed plate fixedly installed on the baffle.

[0011] Preferably, the cleaning device includes two sets of No. 1 support frames fixedly installed on the baffle, a reciprocating screw is rotatably installed between the two sets of No. 1 support frames, a connecting gear is fixedly installed at both ends of the reciprocating screw, a No. 1 limit block is threadedly connected to the reciprocating screw, and a support column is fixedly installed on the No. 1 limit block.

[0012] Preferably, the cleaning device further includes two sets of second support frames fixedly installed on the baffle, a fixing rod fixedly installed between the two sets of second support frames, a second limiting block slidably installed on the fixing rod and fixedly connected to the support column, and a U-shaped cleaning plate fixedly installed on the second limiting block.

[0013] Preferably, the driving device includes a bidirectional motor fixedly mounted on the housing of the device, a connecting rod fixedly mounted on the output end of the bidirectional motor, and a driving gear meshing with a connecting gear fixedly mounted on the connecting rod.

[0014] Preferably, a fixing frame is fixedly installed on the outer shell of the device, and multiple sets of nail teeth are evenly installed on the fixing frame.

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

[0016] 1. This utility model, through the setting of a protective device, uses an electric telescopic rod to move a connecting plate within the device housing. The movement of the connecting plate causes the toothed plate to move, which in turn causes the baffle connected to the gear to rotate. The flying gravel is blocked by the baffle, thus preventing the flying gravel from affecting the efficiency of opening firebreaks during the use of the mowing device.

[0017] 2. This utility model, through the setting of the cleaning device, starts a bidirectional motor to make the connecting rod drive the drive gear to rotate slowly. The rotation of the baffle causes the connecting gear to rotate and mesh with the drive gear. The rotation of the drive gear causes the U-shaped cleaning plate to move, which can clean the baffle. This avoids the situation where the juice and weeds splashed onto the baffle when cleaning weeds will cause the baffle to corrode and reduce its service life if not cleaned in time.

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Example 1

[0026] Reference Figures 1-4 This embodiment proposes a mowing device for a forest firebreak clearing robot, including a device housing 1, a support roller 11 rotatably mounted on the device housing 1, a plurality of blades 12 fixedly mounted on the support roller 11, the blades 12 can be rotated by the support roller 11 to clear weeds, two sets of fixing plates 13 fixedly mounted on the device housing 1, a baffle 14 rotatably mounted on the device housing 1, a fixing frame 5 fixedly mounted on the device housing 1, and a plurality of nail teeth 6 evenly mounted on the fixing frame 5;

[0027] The outer casing 1 is equipped with a protective device 2 to prevent flying debris, and the baffle 14 is equipped with a cleaning device 3 for cleaning it. The outer casing 1 is equipped with a drive device 4. By activating the protective device 2, the baffle 14 is rotated, which in turn drives the cleaning device 3 to rotate. As the drive device 4 is activated, the cleaning device 3 moves on the baffle 14, which can clean the baffle 14 and improve its service life.

[0028] The protective device 2 includes an electric telescopic rod 21 fixedly installed on the outer casing 1 of the device. A connecting plate 22 is fixedly installed on the electric telescopic rod 21. A toothed plate 23 is fixedly installed on the connecting plate 22. An adjusting gear 24 that meshes with the toothed plate 23 is fixedly installed on the baffle 14. The adjusting gear 24 is installed on the connecting shaft that is rotatably connected to the outer casing 1 of the device. This allows the baffle 14 to rotate by rotating the adjusting gear 24. When the equipment is in operation, the electric telescopic rod 21 is activated, which moves the connecting plate 22 inside the outer casing 1 of the device. The movement of the connecting plate 22 moves the toothed plate 23, which in turn rotates the baffle 14 connected to the gear. The flying gravel is blocked by the baffle 14, preventing the flying gravel from affecting the efficiency of opening the firebreak during the use of the mowing device.

[0029] Example 2

[0030] Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the problem that the flying gravel during the use of the mowing device will affect the efficiency of opening firebreaks. If the juice and weeds splashed onto the baffle during weeding are not cleaned in time, the baffle will corrode and its service life will be reduced.

[0031] Reference Figures 1-4 The cleaning device 3 includes two sets of primary support frames 31 fixedly mounted on the baffle 14. A reciprocating screw 32 is rotatably mounted between the two sets of primary support frames 31. Connecting gears 33 are fixedly mounted at both ends of the reciprocating screw 32. A primary limit block 34 is threadedly connected to the reciprocating screw 32. A support column 35 is fixedly mounted on the primary limit block 34. The cleaning device 3 also includes two sets of secondary support frames 36 fixedly mounted on the baffle 14. A fixing rod 37 is fixedly mounted between the two sets of secondary support frames 36. A secondary limit block 38, which is fixedly connected to the support column 35, is slidably mounted on the fixing rod 37. The fixing rod 37 makes the movement of the secondary limit block 38 more stable. A U-shaped cleaning plate 39 is fixedly mounted on the secondary limit block 38. The driving device 4 includes a bidirectional electric drive fixedly mounted on the device housing 1. The bidirectional motor 41 has a connecting rod 42 fixedly installed at its output end. A drive gear 43 that meshes with the connecting gear 33 is fixedly installed on the connecting rod 42. When the bidirectional motor 41 is started, the connecting rod 42 drives the drive gear 43 to rotate slowly. The baffle 14 rotates, causing the connecting gear 33 to rotate and mesh with the drive gear 43. The drive gear 43 rotates, causing the reciprocating screw 32 to rotate within the first limit block 34. This causes the first limit block 34 to drive the second limit block 38, which is connected to the support column 35, to reciprocate on the fixed rod 37. The movement of the second limit block 38 causes the U-shaped cleaning plate 39 to move, which can clean the baffle 14. This prevents the juice and weeds that splash onto the baffle 14 when cleaning weeds from corroding the baffle 14 and reducing its service life if not cleaned in time.

[0032] Working principle: Activating the electric telescopic rod 21 moves the connecting plate 22 within the device housing 1. The movement of the connecting plate 22 moves the toothed plate 23, which in turn rotates the baffle 14 connected to the gear. Splashed gravel is blocked by the baffle 14. Activating the bidirectional motor 41 causes the connecting rod 42 to slowly rotate the drive gear 43. The rotation of the baffle 14 causes the connecting gear 33 to rotate and mesh with the drive gear 43. The rotation of the drive gear 43 causes the reciprocating screw 32 to rotate within the first limit block 34. This causes the first limit block 34 to move the second limit block 38, connected to the support column 35, back and forth on the fixed rod 37. The movement of the second limit block 38 moves the U-shaped cleaning plate 39, which cleans the baffle 14.
