[0002] A bulldozer is an earth-moving engineering machine that can dig, transport and discard rock and soil. It is widely used in open-pit mines. Bulldozers can also be used to loosen soil. The main working device at the rear of the bulldozer, the ripper, can move downward under the action of the oil cylinder and cut into the soil, and then move forward with the bulldozer to complete the loosening of the earth and stone. Most of the current rippers use ripping claws to insert into the soil, but the ripping claws of the existing ripper are fixedly set, and the angle of the ripping claws cannot be adjusted, so the angle of the ripping claws of the ripper cannot be adjusted according to needs. Therefore, we propose a bulldozer ripper with adjustable angle. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Embodiment 1:

[0017] See also Figure 1-3The utility model provides a technical solution: an angle-adjustable bulldozer ripper, comprising a mounting column 1, two groups of connecting arms 2 are arranged on the outer wall of the mounting column 1, five groups of mounting frames 3 are arranged on the outer wall of the mounting column 1, and the five groups of mounting frames 3 are distributed in a linear array on the outer wall of the mounting column 1, a rotating shaft 7 is arranged in the mounting frame 3, one end of the rotating shaft 7 is connected to a bearing 6 arranged on the rear wall of the mounting frame 3, the other end of the rotating shaft 7 passes through the inner front wall of the mounting frame 3 and is connected to a gear 5 arranged outside, a handle 9 is arranged on the front wall of the gear 5, the rear wall of the gear 5 contacts the front wall of the mounting frame 3, a ripping claw 4 is sleeved and installed on the outer wall of the rotating shaft 7, and the front wall of the mounting frame 3 is provided with The fixing component 8 includes a sleeve 80 provided on the front side wall of the mounting frame 3, a sliding plate 82 is slidably connected inside the sleeve 80, guide grooves are provided on the left and right side walls inside the sleeve 80, and guide blocks matching the guide grooves are provided on the left and right side walls of the sliding plate 82. Under the action of the guide grooves and the guide blocks, the sliding plate 82 moves up and down in the sleeve 80 more stably, a hydraulic rod 81 is provided on the top of the sleeve 80, one end of the hydraulic rod 81 is connected to the top of the sliding plate 82, a connecting rod 83 is provided at the bottom of the sliding plate 82, one end of the connecting rod 83 passes through the bottom of the sleeve 80 and is connected to a rack 84 provided on the outside, and the rack 84 is meshed with the gear 5.
