Abstract

The utility model discloses a combined hammer. The combined hammer comprises a hammer handle, a bracket, a hammerhead and a bolt and nut fastener, wherein a hammer shaft hole is formed in one end of the hammer handle, a threaded hole perpendicular to the direction of the hammer shaft hole is formed in the other end of the hammer handle, the tail of the bracket is clamped between the hammer head and the hammer handle, the hammerhead and the bracket have fixed holes which are concentrically communicated with a bolt hole formed in the hammer handle, a bolt is inserted in the fixed holes of the hammerhead and the bracket and the bolt hole of the hammer handle, the other end of the bolt is used for fixing the hammerhead, the bracket and the hammer handle together through a nut, and the nut is cushioned by an elastic washer. The combined hammer has the advantages that the hammerhead is used for protecting the hard alloy bracket which is used for protecting the hammer handle, the hammerhead, the bracket and the hammer handle are mechanically assembled and connected into a whole by the bolt and nut fastener so as to ensure the safe and reliable operation of a hammer crusher, and only the hammerhead needs to be rapidly changed or replaced during overhauling, so that the consumption of metal materials and the labor intensity of worker are greatly reduced; and the service life of the combined hammer is 2-3 times of that of a common alloy steel hammer and is 3-4 times of that of a conventional high manganese steel hammer.

Description

A kind of combination tup

Technical field

The utility model relates to crushing mechanism, is specially a kind of combination tup.

Background technology

Traditional hammer head of hammer crusher is homogenous material manufacture, and stock utilization is extremely low, and material consumption is generally no more than 1/3 and scraps.There is bi-metal composition casting hammer 20 end of the centurys, there are the forms such as castingin alloy or hard alloy hammer, tup is comprised of cutter head and hammer handle two parts but still is structure as a whole, the real cutter head that plays fragmentation is to be made as carbide alloy by high-quality high-abrasive material, hammer handle plays a part to support and addi-tional crusher, stock utilization is constant but significantly improve actual life, due to hammer handle, because being generally common high-abrasive material, makes technological factor, can not accomplish and the same life-span of cutter head, the cutter head that really plays often fragmentation during actual use did not lose efficacy and hammer handle first lost efficacy, cause tup to scrap too early.

Utility model content

The purpose of this utility model is to provide a kind of combination tup; adopt tup protection carbide alloy bracket; carbide alloy bracket protection hammer handle; by bolt fastener machinery assembly and connection all-in-one-piece, design; guarantee that hammer mill running is safe and reliable; short service life with tup in solution prior art, use unsafe problem.

In order to achieve the above object, the technical scheme that the utility model adopts is:

A kind of combination tup, by hammer handle, bracket, tup, bolt and nut securing member four parts, formed, hammer handle one end has hammer axis hole, the other end has the screwed hole vertical with hammer axis hole direction, bracket afterbody is clipped between tup and hammer handle, and tup, bracket have with the bolt hole on hammer handle and have the concentric fixing hole being communicated with mutually, and bolt inserts in the fixing hole and bolt hole of tup, bracket and hammer handle, the bolt other end is fixed together tup, bracket and hammer handle through nut, the flexible packing ring of nut underlay.

Described a kind of combination tup, is characterized in that: soldering cemented carbide part wear-resistant block on described bracket.

Described a kind of combination tup, is characterized in that: the reducing shape that the fixing hole bottom on described tup is semicircle shape, bolt top is firmly placed in tup fixing hole, and tup, bracket and hammer handle are firmly fixed together.

Described a kind of combination tup, is characterized in that: described tup is with two prismatic angles, and both sides are circular arc.

The utility model adopts tup protection carbide alloy bracket; carbide alloy bracket protection hammer handle; by bolt fastener machinery assembly and connection all-in-one-piece, design; guarantee that hammer mill running is safe and reliable; during maintenance, only need Quick-changing or change tup, greatly reducing metal material consumption and labor strength.Be 2 ~ 3 times of common steel alloy service life, 3 ~ 4 times of traditional potassium steel.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is top view of the present utility model.

The specific embodiment

As shown in Figure 1.A kind of combination tup, by hammer handle 1, bracket 6, tup 2, bolt 3 nut 5 securing member four parts, formed, hammer handle 1 one end has hammer axis hole 7, the other end has the screwed hole vertical with hammer axis hole 7 directions, bracket 6 afterbodys are clipped between tup 2 and hammer handle 1, tup 2, bracket 6 have with the bolt hole on hammer handle 1 and have the concentric fixing hole being communicated with mutually, bolt 3 inserts in the fixing hole and bolt hole of tup 2, bracket 6 and hammer handle 1, bolt 3 other ends are fixed together tup 2, bracket 6 and hammer handle 1 through nut 5, the flexible packing ring 4 of nut 5 underlay.

Soldering cemented carbide part wear-resistant block 8 on described bracket.

The reducing shape that fixing hole bottom on described tup is semicircle shape, bolt 3 tops are firmly placed in tup 2 fixing holes, and tup 2, bracket 6 are firmly fixed together with hammer handle 1.

Described tup 2 is with two prismatic angles, and both sides are circular arc.
