Abstract
The utility model discloses a counterattack plate for a rotor body of a vertical spindle type crusher. The counterattack plate comprises a counterattack plate (1), wherein the counterattack plate (1) is mounted between a rotor upper disc (2) and a rotor lower disc (3) of the rotor body and is formed by splicing at least two small rotor body counterattack plates (4). By machining the conventional integrally-designed counterattack plate of a wear-resistant part into zoning structures, the counterattack plate has the advantages that (1) by utilizing the zoning and combined structures, the local exchanging can be carried out according to the corresponding worn zones, and the later-period maintenance cost and maintenance frequency can be substantially decreased relative to the conventional integral structure; and (2) in a manufacture process, the limitations such as big molds and the fluidity and the cooling property of liquid steel during casting are avoided, the phenomena such as air holes, loosening and fissure are greatly reduced, and the casting quality is well improved.
Description
Technical field
The utility model relates to a kind of counterpunch board of vertical shaft crusher rotor block, belongs to the impact crusher equipment technical field.
Background technology
Vertical shaft crusher is vertical impact crusher, its broken core is rotor block, the profile of rotor block is a hollow cylinder, constituted by upper rotor part lower wall and the cutting plate that is positioned at backplate, on the rotor, lower wall and cutting plate constitute each emission runner, at the emission runner exit material casting head and the counterpunch board that special material is made is installed, after material is sent into rotor block by tripper, material enters different emission runners under action of centrifugal force, and under centrifugal force accelerate to the impelling of 60-75m/s speed and go out, impact the material lining in the whirling motion crusher chamber, carry out strong pulverizing certainly.In use because material launches between crusher chamber and rotor block mutually, so counterpunch board also belongs to vulnerable part, need its frequent replacing.No matter the broken rotor of existing vertical shaft is the wearing piece of what shape, same position all is to adopt one-piece parts to make, advantage simple in structure, easy to make is so no doubt arranged, but in the monoblock if there is the subregion problem of serious wear to occur, will require monoblock to replace, have the lower problem of effect, counterpunch board all is to adopt the higher high-abrasive material manufacturing of cost simultaneously, certainly exists very serious waste like this.
Summary of the invention
The technical problems to be solved in the utility model is: the counterpunch board of the vertical shaft crusher rotor block that provide a kind of utilization rate height, saves production cost can overcome the deficiencies in the prior art.
The technical solution of the utility model is: the counterpunch board of vertical shaft crusher rotor block, and it comprises counterpunch board, and counterpunch board is installed on the rotor of rotor block between the dish and rotor lower wall, and counterpunch board is made of the little counterpunch board amalgamation more than two.
Offer screw at every little counterpunch board.
Counterpunch board is made of three little counterpunch board amalgamations.
Compared with the prior art, the utility model will have the structure that is processed into the subregion formula for the wearing piece counterpunch board of global design now, have the following advantages like this:
1, take the box-like structure of partition group, can carry out local replacing according to corresponding eroded area, existing relatively overall structure can significantly reduce later maintenance cost and frequency of maintenance;
2, on the make, mould is bigger when no longer being subjected to monoblock cast, and the restriction of molten steel flowability, cooling property etc. has greatly reduced phenomenons such as pore, loose, crackle, has improved castability preferably.
3, can change different counterpunch boards according to the difference of broken material, to be applicable to the broken requirement of different materials or material;
4, can find zone easy to wear at work, all the other adopt more higher leveled wearing piece, reduce frequency of maintenance with it.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model mounting structure schematic diagram.
The specific embodiment
Embodiment 1: as illustrated in fig. 1 and 2, the formation of rotor block comprise coil 2 on the rotor, rotor lower wall 3, counterpunch board 1 and material casting 5, counterpunch board 1 and material casting 5 is between rotor dish 2 and rotor lower wall 3, counterpunch board 1 in this example is made of little counterpunch board 4 amalgamations more than two, preferred three, its fixed form is to offer screw at every little counterpunch board 4, passes through bolting.
Claims (3)
1. the counterpunch board of a vertical shaft crusher rotor block, it comprises counterpunch board (1), counterpunch board (1) is installed on the rotor of rotor block between the dish (2) and rotor lower wall (3), and it is characterized in that: counterpunch board (1) is made of little counterpunch board (4) amalgamation more than two.
2. the counterpunch board of vertical shaft crusher rotor block according to claim 1 is characterized in that: offer screw at every little counterpunch board (4).
3. the counterpunch board of vertical shaft crusher rotor block according to claim 1, it is characterized in that: counterpunch board (1) is made of three little counterpunch boards (4) amalgamation.
