Description

A kind of counterattack parts of impact breaker

Technical field

The utility model relates to the modular construction of impact breaker, the counterattack portion group of specifically a kind of impact breaker Part.

Background technique

Impact breaker be it is a kind of broken equipment is carried out to material using percussion, its reduction ratio is big, broken effect Rate is high, therefore is widely used in the industrial departments such as metallurgy, building materials, light industry, chemical industry and electric power.The effect of counterpunch board is subject to be turned The material that bar on son is hit impact grinding on it, and broken material is rebounded fracture area again, it carries out again It is broken.The main of existing impact breaker realizes crushing material by the beating lining plate and material impacting in counterattack portion, and hits There is certain arbitrariness in the direction for hitting smashed material rebound, so as to cause the material of crushing requirement is reached after crushing again It is repeated several times by the bar on reprinting and hits beating lining plate, so that broken material is easy to cause to occur crushing excessive phenomenon.

Utility model content

The problems solved by the utility model are: providing a kind of counterattack parts of impact breaker, can guide not The fragment of same volume rebounds to different directions, prevents the material repeated impact for reaching crushing requirement from leading to crushing phenomenon.

Corresponding technical solution is as follows: a kind of counterattack parts of impact breaker, including shell, crusher chamber, discharge Mouth, rotor, preceding impact rack, rear anti-rack, the preceding impact rack, rear impact rack top be connected with adjustable support, it is described adjustable Bracket extends to the hull outside；The preceding impact rack, rear impact rack lower part are connected with multiple beating lining plates, the counterattack lining It is connected with lines plate on plate, the top of the contact surface of the lines plate and fragment is made of multiple lug bosses, the lug boss A lateral section be upper convex surface, the section of the other side is concave surface, the top on the upper convex surface and the top phase of the concave surface Cusp is formed at friendship；Joint face is provided at the lower edges of the lines plate, the joint face surface is plane, the company Connecting hole is provided in junction, the connecting hole is threadedly coupled by screw with the beating lining plate.

Further, the section of the lines plate is that curl is trapezoidal, and it is trapezoidal that lines plate section is formed by curl Upside height is higher than downside height.

Further, the section of the edge of the joint face is inclined-plane.

Further, the distance between described cusp on the lines plate is slightly larger than the diameter that ore reduction requires.

Further, the middle part on the upper convex surface of the lines plate lug boss is provided with cushion.

Further, the cushion is rubber buffer.

The utility model has the following beneficial effects: counterattack parts have preceding impact rack, rear impact rack, beating lining plate, lines plate Composition, so as to be replaced for damage component, to realize readily replaceable, the purpose of save the cost.By in preceding counterattack Lines plate is connected on frame, rear impact rack, the cusp of the lines plate can make material, with bigger pressure, make when hitting Material is more easily broken, and the distance between cusp desired diameter broken slightly larger than material, so that broken material size Closer to desired size.The cushion being arranged on the upper convex surface of lines plate can prevent from meeting the material of broken diametric requirements again It is broken, cause to crush excessive phenomenon.Material can be rebounded fracture area again by hitting cusp, and material up to specification can also be by Upper convex surface is oriented to discharge gate, so that the different size of material made has certain guiding performance, crushing efficiency is higher.

Appended drawing reference: 1- rotor, 2- shell, 3- adjustable support, impact rack before 4-, impact rack after 5-, 6- beating lining plate, 7- Lines plate, 8- crusher chamber, 9- discharge gate, 71- concave surface, the upper convex surface 72-, 73- cushion, 74- cusp, 75- joint face, 76- Lug boss, 77- connecting hole.

Specific embodiment

More detailed description is done to the embodiments of the present invention below in conjunction with attached drawing and appended drawing reference, makes to be familiar with ability The technology people in domain can implement accordingly after studying this specification carefully.It should be appreciated that specific embodiment described herein is only to solve The utility model is released, is not used to limit the utility model.

Referring to Fig. 1, Fig. 2, a kind of counterattack parts of impact breaker, including shell 2, crusher chamber 8, discharge gate 9, turn Sub 1, preceding impact rack 4, rear anti-rack 5, the preceding impact rack 4, rear impact rack 5 top be connected with adjustable support 3, it is described adjustable Bracket 3 extends to outside the shell 2；The preceding impact rack 4,5 lower part of rear impact rack are connected with multiple beating lining plates 6, described Lines plate 7 is connected on beating lining plate 6, the top of the lines plate 7 and the contact surface of fragment is made of multiple lug bosses 76, One lateral section of the lug boss 76 is upper convex surface 72, and the section of the other side is concave surface 71, the top on the upper convex surface 72 with The top intersection of the concave surface 71 forms cusp 74；Joint face 75, institute are provided at the lower edges of the lines plate 7 Stating 75 surface of joint face is plane, is provided with connecting hole 77 on the joint face 75, the connecting hole 77 by screw with it is described Beating lining plate 6 is threadedly coupled.

When specific works, material enters in the crusher chamber 8 from feeding inlet, by the pendulum on the rotor 1 by material It hits to the lines plate 7, is crushed material by what the cusp 74 on the lines plate 7 can be more easier, break Material after broken is oriented to back on the rotor 1 by the cusp 74 to be repeatedly crushed, after material, which reaches broken, to be required, object Material may pass through when hitting the lines plate 7 again to be hit between two cusps 74 to the cushion 73 on the upper convex surface 72, The cushion 73 can prevent material to be crushed again, and material can be oriented to crusher by elasticity caused by the cushion 73 The discharge gate 9 at.

Preferably, the section of the lines plate 7 is that curl is trapezoidal, and it is trapezoidal that 7 section of lines plate is formed by curl Upside height is higher than downside height, so that the rebound guiding described in material impacting when lines plate 7 is intended to the discharge gate 9, makes The crushing efficiency of material is higher.

Preferably, the section of the edge of the joint face 75 is inclined-plane, more easy sticker between the adjacent lines plate 7 It closes, prevents from generating conflict when installation, reduce abrasion.

Preferably, the distance between described cusp 74 on the lines plate 7 is slightly larger than the broken desired diameter of material, directly Diameter generates cusp 74 described in material impacting when being greater than the distance between two described cusps 74 broken, and diameter is less than two cusps Material may pass through between two cusps 74 to hit to the cushion 73 when the distance between 74.

Preferably, the middle part on the upper convex surface 72 of 7 lug boss 76 of lines plate is provided with cushion 73, the cushion 73 can prevent the material for meeting broken requirement to be crushed overground phenomenon occur again.

Preferably, the cushion 73 is rubber buffer, and the rubber buffer has certain elasticity, can be more effective Material is directed to the discharge gate 9.

The above are a kind of embodiments of the utility model, and the description thereof is more specific and detailed, but cannot therefore understand For a limitation on the scope of the patent of the present invention.It should be pointed out that for those of ordinary skill in the art, not taking off Under the premise of design from the utility model, various modifications and improvements can be made, these belong to the guarantor of the utility model Protect range.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
