Description
Technical Field
The utility model relates to a single hook tooth especially relates to a crescent locking formula single hook tooth.
Background
At present, in the implementation of projects such as engineering construction, mining and the like, the hard rock stratum is usually vibrated and loosened and stripped by adopting traditional construction methods such as powder blasting and the like, the construction method is low in safety and operation efficiency, high in production cost, deficient in the research on the crushing type scarifier in China, lack of systematic research on the design of the crushing type scarifier and free of corresponding products in China.
When engineering machinery such as a bulldozer, a land leveler and the like uses the scarifier to loosen soil, because the operating environment is severe and complex, the working load and the impact load are large, the front-end equipment body hook arm and the tooth point of the scarifier are stressed greatly and easily damaged, the service life of the equipment body hook arm and the tooth point is influenced, the cost is increased, and the working efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a double-crescent locking type single hook tooth.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model comprises an equipment body digging arm and bucket teeth, wherein the equipment body digging arm is provided with a locking mechanism, the locking mechanism comprises a first crescent-shaped connecting piece, a second crescent-shaped connecting piece and a detachable tooth holder, the bucket teeth are connected with the equipment body digging arm through the detachable tooth holder, the bucket teeth are provided with a first boss and are in fit connection with the detachable tooth holder, the detachable tooth holder is provided with a second boss and is in fit connection with the equipment body digging arm, the first boss is provided with an arc-shaped groove matched with the first crescent-shaped connecting piece, after the first boss is in fit connection with the detachable tooth holder, the arc-shaped groove and the detachable tooth holder form a slide-in groove capable of accommodating the first crescent-shaped connecting piece, the second boss of the detachable tooth holder is provided with an arc-shaped groove matched with the second crescent-shaped connecting piece, after the second boss is matched and connected with the digging arm of the equipment body, the arc-shaped groove and the digging arm of the equipment body form a sliding groove capable of accommodating the second crescent-shaped connecting piece.
Specifically, a first locking opening is formed in the detachable tooth holder.
Furthermore, a second locking port is formed in the digging arm of the equipment body.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a crescent retaining member of two or more than two makes equipment body dig the arm under the prerequisite of normal work, avoids the unbalanced atress of bucket tooth and the connecting plate that leads to impaired, can realize excavating the stress concentration who loosens the soil when the operation avoids because of receiving in a large scale and lead to equipment body to dig the arm impaired, makes things convenient for the excavation and the transportation of material.

in the figure: 1-bucket teeth, 2-first crescent connecting pieces, 3-detachable tooth holders, 4-second crescent connecting pieces, 5-digging arms of the equipment body, 6-second bosses and 7-first bosses.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, the utility model discloses an equipment body digs arm 5 and bucket tooth 1, be provided with locking mechanism on the equipment body digs arm 5, locking mechanism includes first crescent connecting piece 2, second crescent connecting piece 4 and can dismantle toothholder 3, bucket tooth 1 passes through can dismantle toothholder 3 with equipment body digs arm 5 and connects, bucket tooth 1 be provided with first boss 2 and with can dismantle toothholder 3 cooperation and connect, can dismantle toothholder 3 be provided with second boss 6 and with equipment body digs arm 5 cooperation and connects, first boss 7 be provided with first crescent connecting piece 2 complex arc wall, first boss 7 with can dismantle toothholder 3 cooperation and connect the back the arc wall with can dismantle toothholder formation can hold the sliding groove of first crescent connecting piece 2, the second boss 6 of dismantling toothholder 3 be provided with second crescent connecting piece 4 complex arc wall After the second boss 6 is matched and connected with the equipment body digging arm 5, the arc-shaped groove and the equipment body digging arm 5 form a sliding groove capable of accommodating the second crescent-shaped connecting piece 4.
The detachable tooth holder 3 is provided with a first locking port.
And a second locking port is arranged on the digging arm 5 of the equipment body.
During operation, with engineering machine tool's such as excavator equipment body dig arm 5 through can dismantle toothholder 3 with bucket tooth 1 connects the back, carries out construction operation to the workplace, because equipment body digs arm 5 and is provided with two or crescent retaining members more than two for can realize the large tracts of land excavation operation of loosening the soil on the material base member on a large scale, make equipment body dig arm 5 under the prerequisite of normal work, avoid the unbalanced stress of bucket tooth 1 and the connecting plate that leads to impaired, perhaps lead to the connecting plate impaired because the stress concentration that receives, make things convenient for the excavation and the transportation of material.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
