[0014] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is now further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the relevant components of the utility model.

[0015] According to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0016] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1 and Figure 2As shown, an excavator ripper includes a connecting seat 1, a support arm 2 and a claw body 4. The top of the connecting seat 1 is connected to the working end of the excavator. Driven by the forearm joint of the excavator, the ripper is used to perform a loosening operation.

[0018] A pin shaft 11 connected to the working end of the excavator is provided on both sides of the top of the connection seat 1, and fasteners 12 are provided at both ends of the pin shaft 11. The pin shaft 11 passes through the two side plates of the connection seat 1, and the forearm probe of the excavator is also penetrated and fixed between the two side plates of the connection seat 1. The fasteners 12 fix the pin shaft 11 leaking from both sides to the two side plates of the connection seat 1 so that it will not fall off.

[0019] During implementation, the bottom of the connecting seat 1 is fixedly connected to the arm 2 to improve stability. The arm 2 is an arc-shaped plate-like structure, which can better adapt to different terrains when the excavator lifts the ripper and descends. The lower sides of the arm 2 are detachably connected to the claw body 4 through the claw handle 3.

[0020] Specifically, the upper part of the claw handle 3 is a shuttle-shaped structure, and the upper part of the claw handle 3 is fixedly connected to the support arm 2 through a locking rib 31, and the locking rib 31 is an inverted L-shaped structure to provide stable support for the whole. The bottom of the claw handle 3 is detachably connected to the claw body 4 through a positioning shaft 32. When the claw body 4 is severely worn, only the claw body 4 can be replaced, and the claw handle 3 can continue to be used.

[0021] In order to improve the overall stability of the ripper, the connection base 1, the support arm 2, and the claw handle 3 can be designed as an integrated connection, and its stability can be achieved through integrated casting. Compared with welding fixation, the integrated cast ripper can have an overall force effect, so that it has a longer service life. As a preferred solution, HT450 gray cast iron is used in casting, which has good wear resistance and shock absorption performance.

[0022] In addition, a rib plate 21 is provided at the connection between the support arm 2 and the connection seat 1, and at least two rib plates 21 are provided on each side. Three rib plates 21 can be provided, for example, two are provided at the ends of both sides of the connection, and one is provided in the middle. As a preferred mode, reinforcement blocks 22 are provided on both sides of the middle part of the support arm 2, and the two sides of the reinforcement blocks 22 are beveled, which can disperse debris when loosening the soil and reduce the impact force on the support arm 2.

[0023] In the present soil loosening device, a groove 41 is provided on the lower peripheral corner of the claw body 4. When the soil loosening device is inserted into soil or concrete, the groove 41 disperses the soil or concrete encountered on the ground, so that the soil loosening device can be better inserted into the ground and vibrate the ground well to achieve the purpose of loosening the soil. A wear-resistant block 42 is provided on the side of the claw body 4. The wear-resistant block 42 increases the wear resistance of the claw body 4. Only when the wear-resistant block 42 is completely worn will it affect the main structure of the claw body 4. Therefore, it is very necessary to provide the wear-resistant block 42.

[0024] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
