The invention provides a clamp-breaking prevention scarification tooth which comprises a tooth disc and scarification tooth bodies. A through hole is formed in the center of the tooth disc. An inward-concave annular groove is formed in the ring face of the tooth disc. The number of the scarification tooth bodies is at least three. Each scarification tooth body comprises a tooth rod and a tooth top. The tooth rods are inserted and arranged in the annular groove in the radial direction of the tooth disc. A reset spring is arranged at the position, corresponding to each tooth rod, of the groove bottom of the annular groove. One end of each reset spring is fixedly connected to the groove bottom. An ejector block is arranged at the other end of each reset spring. Each ejector block is connected with the corresponding tooth rod. The clamp-breaking prevention scarification tooth is simple in structure and reasonable in design. During hard soil layer operation, switching of the scarification tooth can be achieved, the situation that the scarification tooth is broken off due to too large resistance is avoided, and the service life of a scarifier is prolonged.

Example Embodiment

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0017] Such as figure 1 As shown, the present invention provides an anti-seize and break loosening tooth, including a tooth plate 1 and a loosening tooth. A through hole 2 is provided in the center of the gear plate 1 for mounting the rotating shaft. A key groove 10 is provided on the inner wall of the through hole 2. The rotating shaft and the gear plate 1 are connected by a key.
[0018] A concave annular groove is provided on the ring surface of the gear plate 1, and ripper teeth are installed on the bottom 5 of the annular groove, and the ripper teeth are uniformly arranged in the groove cavity of the annular groove. The loosening tooth includes a toothed rod 3 and a tooth tip 4, and the toothed rod 3 is inserted and arranged in an annular groove along the radial direction of the toothed disk 1. The loosening teeth are steel loosening teeth with high strength.
[0019] A top block 7 is provided at the end of the toothed rod, a reset spring 6 is connected to the top block 7 and the other end of the reset spring 6 is fixedly connected to the bottom 5 of the annular groove. In order to make the toothed rod 3 telescopically move in the radial direction of the toothed disc 1, the present invention is provided with a limiting groove 8 on the inner wall of the annular groove. The limiting groove 8 includes two limiting groove walls, and the toothed rod 3 is arranged in the limiting position. In the groove 8 and move along the groove wall of the limiting groove 8.
[0020] As an embodiment, the present invention is provided with 5 ripper teeth, the number of ripper teeth can also be multiple, and the plurality of ripper teeth are evenly arranged, and a wear-resistant sleeve 9 is provided on the tooth tip 4 to protect the ripper Tooth tip to reduce wear and extend the service life of loosening teeth, thereby saving maintenance costs.
[0021] The working principle of the present invention is: when in use, the gear plate rotates with the rotating shaft. During loosening operations, when encountering a hard soil layer, the loosening teeth in working state will be compressed inward under force, the return spring will deform under pressure, and the loosening teeth under force will retract into the gear plate, and the adjacent loosening teeth The teeth continue to work to realize the function of switching the loosening gears and avoid the loosening gears from breaking due to excessive force.
