DETAILED DESCRIPTION
[0037] The present application is further described in detail below in conjunction with the accompanying drawings.
[0038] The embodiment of the present application discloses a diversion type protective device for brush cutting equipment.
[0039] Example 1
[0040] Reference Figure 1 , Figure 2 and Figure 3 , including a connecting rod 1 and a guide. The connecting rod 1 is L-shaped, and one end of the connecting rod 1 is used to connect to the operating rod 81 of the brush cutter 8. After the connection of the connecting rod 1 is completed, a part of the connecting rod 1 is perpendicular to the operating rod 81, and the other part of the connecting rod 1 is arranged above the operating rod 81 in parallel with each other. The guide is arranged at the end of the connecting rod 1. After the installation of the connecting rod 1 is completed, the guide is located in front of the blade 82 of the brush cutter 8, and the guide is located above the blade 82 of the brush cutter 8, so that the guide can contact the bushes first during the movement of the brush cutter 8.
[0041] Reference Figure 1 and Figure 2 The top surface of the guide member is provided with a first guide surface 2 and a second guide surface 3, both of which are planes, and the first guide surface 2 and the second guide surface 3 are arranged at an angle, and the angle between the two is 90°. Therefore, during the advancement of the brush cutter 8, the guide member and the connecting rod 1 can advance along with the brush cutter 8, the guide member first contacts the bushes, and the guide member moves the bushes on both sides to both sides respectively, so that the top of the bushes is in a bent state; then after the brush cutter 8 cuts the bushes, the bushes on both sides can fall toward the side away from each other, so that the fallen bushes are not easy to fall on the moving path of the brush cutter 8, and are not easy to cause secondary cutting, which helps to ensure the safety of the working process.
[0042] The guide member includes two baffles 4, which are in the shape of a right triangle, and the edge of the baffle 4 includes two right-angled sides and a hypotenuse, and the hypotenuses of the two baffles 4 are abutted against each other and fixedly connected together; the two baffles 4 are symmetrically arranged and are both welded to the ends of the connecting rod 1. Therefore, the structure of the guide member is simple, the manufacturing cost is low, and the end of the guide member is arranged in a sharp shape, so that the guide member is easier to insert between the two bushes during the movement, thereby moving the bushes on both sides to the two sides respectively.
[0043] Reference Figure 1 and Figure 2 The end of the connecting rod 1 away from the baffle 4 is provided with a mounting assembly 6, and the mounting assembly 6 includes a first mounting piece 61, a second mounting piece 62, a locking bolt 63 and a locking nut 64. The first mounting piece 61 is welded to the end of the connecting rod 1, and a curved surface matching the operating rod 81 of the brush cutter 8 is provided on the side of the first mounting piece 61 away from the connecting rod 1; the second mounting piece 62 is symmetrically arranged with the first mounting piece 61, and the shape of the second mounting piece 62 is the same as that of the first mounting piece 61. There are two locking bolts 63 and two locking nuts 64; both ends of the first mounting plate 61 and the second mounting plate 62 are provided with connection holes, and the two locking bolts 63 are respectively inserted into the connection holes at both ends of the first mounting plate 61; the ends of the locking bolts 63 pass through the connection holes on the second mounting plate 62, and the locking nuts 64 are threadedly connected to one end of the locking bolts 63 passing through the connection holes, so that the first mounting plate 61 and the second mounting plate 62 are fixedly connected to the operating rod 81 of the brush cutter 8, and the installation of the connecting rod 1 and the guide member is completed. Therefore, by adjusting the installation position of the connecting rod 1 relative to the operating rod 81, the height of the guide member can be adjusted, so as to adapt to shrubs of different heights and ensure the use effect of the guide member.
[0044] Furthermore, a flexible pad is bonded to one side of the first mounting piece 61 and the second mounting piece 62 that are close to each other. The flexible pad is a rubber pad with a certain elasticity. Therefore, the flexible pad can be pressed tightly between the first mounting piece 61 and the operating rod 81 and between the second mounting piece 62 and the operating rod 81, thereby increasing the friction at the connection and enhancing the installation effect of the connecting rod 1.
[0045] The implementation principle of Example 1 is as follows: when the brush cutter 8 moves forward, the baffle 4 first contacts the bushes. As the baffle 4 moves, the baffle 4 can push the bushes on both sides to both sides respectively, so that the top of the bushes is in a bent state; then as the brush cutter 8 moves forward, the blade 82 cuts off the bent bushes, and the bushes on both sides fall toward the side away from each other, so that the bushes are not likely to fall on the travel path of the blade 82, and it is not likely to cause secondary cutting, making the working process safer.
[0046] Example 2
[0047] Reference Figure 4The difference between this embodiment and embodiment 1 is that the guide member in this embodiment is a guide block 5, which is welded to the end of the connecting rod 1; the guide block 5 is a solid tetrahedron structure, and the first guide surface 2 and the second guide surface 3 are both arranged on the top surface of the guide block 5; therefore, the guide block 5 can move the shrubs to both sides and play a guiding role.
[0048] Reference Figure 4 and Figure 5 In this embodiment, a support block 611 is fixedly connected to the first mounting plate 61. Two support blocks 611 are provided and spaced and parallel. The connecting rod 1 is hinged between the two support blocks 611. The hinge axis of the connecting rod 1 is perpendicular to the axis of the operating rod 81. A threaded hole is provided on the connecting rod 1. The axis of the threaded hole is parallel to the hinge axis of the connecting rod 1. A fixing bolt 7 is threadedly connected in the threaded hole. Correspondingly, a through hole 6111 is provided on the support block 611. The axis of the through hole 6111 is parallel to the axis of the threaded hole. There are two through holes 6111 on the support block 611, which correspond to the two states of the connecting rod 1. When the end of the fixing bolt 7 is screwed into one of the through holes 6111, the longer section of the connecting rod 1 is in a state parallel to the operating rod 81; when the end of the fixing bolt 7 is screwed into the other through hole 6111, the longer section of the connecting rod 1 is in a state perpendicular to the operating rod 81. Therefore, when there is an obstacle on the travel path that blocks the guide block 5, the connecting rod 1 can be rotated to a state perpendicular to the operating rod 81, and then the fixing bolt 7 is screwed in to fix the connecting rod 1. At this time, the brush cutter 8 can be pushed forward to continue cutting the bushes.
[0049] The present application also discloses a brush cutting device, referring to Figure 6 , including a brush cutter 8 and the diversion type protective device for brush cutters in the above-mentioned embodiment. The brush cutter 8 includes an operating rod 81 and a blade 82, and the blade 82 is rotatably arranged at one end of the operating rod 81. The end of the connecting rod 1 away from the guide member and the end of the operating rod 81 close to the blade 82 are fixedly connected by a locking bolt 63 and a locking nut 64. Therefore, by holding the operating rod 81 and moving it, the guide member can first push away the bushes on the moving path, so that the bushes on both sides are in a state of bending to the side away from each other; then as the blade 82 moves, the blade 82 can cut the bushes, so that the bushes on both sides fall to the side away from each other.
[0050] The operating rod 81 is provided with a scale 811 along its length direction, so that it is convenient to observe the installation position of the connecting rod 1 relative to the operating rod 81 , thereby facilitating the adjustment of the connecting rod 1 .
[0051] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
