In order to solve the technical problem, the utility model discloses a following technical scheme realizes:

the utility model provides an install buffer on electric pick, includes a preceding section of thick bamboo, there is the iron head one side of a preceding section of thick bamboo through the screw connection, be provided with the cylinder in the preceding section of thick bamboo, impact bar and jump bit, the one end of impact bar with the iron head is connected, the other end with the jump bit contact, the cylinder liner is in the impact bar with the outside of jump bit, the cover is equipped with the buffering packing ring in proper order on the impact bar, buffering rubber ring and cushion socket, a pot head of cylinder is established the outside of cushion socket, and with the iron head contact, the buffering packing ring with the buffering rubber ring is located the impact bar with between the iron head.

Preferably, the number of the buffer rubber rings is 2, and a gasket is arranged between 2 buffer rubber rings.

Preferably, a first sealing rubber ring is arranged between the buffer seat and the impact rod.

Preferably, a second sealing rubber ring is arranged between the buffer seat and the cylinder.

The utility model has the advantages that: the utility model discloses a buffer, moreover, the steam generator is simple in structure, through the buffering packing ring, the design of buffering rubber ring and cushion socket, the effect of two-way buffering around having realized, when the air hammer phenomenon appears in the electric pick, the jump bit can strike the cushion socket in advance before the impact bar strikes the iron head, the impact energy of jump bit can be absorbed through the cushion socket by blotter ring and buffering rubber ring like this, the impact energy of jump bit is buffered in advance, the impact strength to the iron head has significantly reduced, avoid the damage of screw and preceding section of thick bamboo, the stability in use and the validity of product are improved.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1-4, a buffering device installed on an electric pick comprises a front barrel 1, one side of the front barrel 1 is connected with an iron head 3 through a screw 2, a cylinder 4, an impact rod 5 and an impact hammer 6 are arranged in the front barrel 2, one end of the impact rod 5 is connected with the iron head 3, the other end of the impact rod 5 is in contact with the impact hammer 6, the cylinder 4 is sleeved outside the impact rod 5 and the impact hammer 6, a buffering gasket 7, a buffering rubber ring 8 and a buffering seat 9 are sequentially sleeved on the impact rod 5, one end of the cylinder 4 is sleeved outside the buffering seat 9 and is in contact with the iron head 3, and the buffering gasket 7 and the buffering rubber ring 8 are located between the impact rod 5 and the iron head 3.

When the buffer device is normally used, as shown in fig. 3, the impact hammer 6 pushes the impact rod 5, and then the impact rod 5 pushes the iron head 3 to act, at the moment, the impact hammer 6 does not contact the buffer seat 9, and the first buffer component and the second buffer component play a conventional buffer role; when the electric pick has the empty hammer phenomenon, as shown in fig. 4, the impact hammer 6 pushes the impact rod 5, when the impact rod 5 is not in contact with the iron head 3, the impact hammer 6 firstly impacts the buffer seat 9, the force generated by the impact hammer 6 is effectively buffered through the first buffer component and the second buffer component, and the force of the impact rod 5 impacting the iron head 3 is greatly reduced. The utility model discloses a buffer device, simple structure, through buffering packing ring 7, the design of buffering rubber ring 8 and buffering seat 9, the effect of two-way buffering around having realized, when the electric pick appears the empty hammer phenomenon, jump bit 6 can strike buffering seat 9 in advance before impact rod 5 strikes iron head 3, so the impact energy of jump bit 6 can be absorbed by buffering packing ring 7 and buffering rubber ring 8 through buffering seat 9, the impact energy of jump bit 6 is buffered in advance, the impact strength to iron head 3 has been greatly reduced, avoid the not hard up of screw 2, and the damage of screw 2 and front cylinder 1, improve the stability in use and the validity of product; the utility model discloses carry out coaxial cooperation between well buffing pad 9 and the cylinder 4, the cooperation installation of buffing pad 9 and impact bar 5 has played the guide effect for impact bar 5, has realized empty hammer buffering effect in same installation space, simultaneously, but the optional screw 2 and the material of preceding section of thick bamboo 1, the use cost that has significantly reduced.

The number of the buffer rubber rings 8 is 2, and a gasket 10 is arranged between the 2 buffer rubber rings 8. The design can be an integrated rubber ring or an independent accessory, can effectively absorb the force generated by the impact hammer 6, and improves the using effect of the product.

A first sealing rubber ring 11 is arranged between the buffer seat 9 and the impact rod 5. Above-mentioned design can be for setting up the annular groove on the outer wall of impact rod 5, and the cooperation of first sealing rubber circle 10 is installed in the annular groove to strengthen the leakproofness between buffer seat 9 and the impact rod 5, play the effect that increases damping, thereby produce the cushioning effect to impact rod 5, avoid producing the phenomenon that the air hammer is hit in succession.

A second sealing rubber ring 12 is arranged between the buffer seat 9 and the air cylinder 4.
