Abstract

The utility model discloses a combined breaking hammer, and relates to a crusher. The combined breaking hammer is composed of a hammer handle (1) and a hammer head (2). A jointing hole (3) is provided above the hammer handle (1). The utility model is characterized in that a U-shaped base (5) is provided below the hammer handle (1); and an assembling opening (4) is provided at the middle part; a through hole (6) is provided at the central part of the U-shaped base (5); the hammer head (2) is a solid object which has a cross section shaped like a trapezoid and the other cross section shaped like a rectangle. The top part is provided with a projection (7) which is provided with a screw hole (8) at the middle part. The shape and size of the projection (7) are corresponding with the U-shaped base (5). The hammer handle (1) and the hammer head (2) are fixed by screws (9). The hammer head of the utility model is made of a high-chromium alloy material with hardness up to HRC60-65. Therefore the durability of the hammer is better than that of the common breaking hammer. Only replacing the hammer head is required when abrasion occurs. If abrasion occurs on the hammer handle, the repair welding can be performed for restoring and reusing. The service life of the breaking hammer is 3-8 times of that of the common forging hammer or the high-manganese steel hammer. The combined breaking hammer furthermore has the advantages of convenient installation, simple detachment, reduced crushing cost, prolonged operation time of crusher, and excellent economic benefit.

Description

The wear-resisting quartering hammer of combined type

Technical field

The utility model relates to disintegrating machine, furthermore, relates to the rotation hammer of disintegrating machine.

Background technology

Traditional disintegrating machine is usually used in sanding, and its rotation hammer promptly is the sanding hammer, is made by unitary steel material, though hammer into shape durable, tup is not wear-resisting, is consumable accessory.In order to improve the anti-wear performance of tup, people have designed some schemes, having of application Chinese patent: ZL99222815.8 number " confusion type tup ", ZL200720008179.0 number " hammehead structure of ore crusher ", ZL200820081156.7 number " a kind of bimetallic composite hammer head ", ZL200820148170.4 number " combined type quartering hammer " etc., these patented technologies all have the effect of certain reinforcement tup, but owing to adopt wear-resistant material to make tup, and be not easy processing.Therefore people still constantly bring forth new ideas, design more wear-resisting, process easier tup.

Summary of the invention

The purpose of this utility model provides the wear-resisting quartering hammer of a kind of combined type, not only easily processing and fabricating but also strengthen the wearability of tup effectively.

The wear-resisting quartering hammer of the combined type that the designer provides is made up of hammer handle and tup, and there is the sleeve joint hole with the rotating shaft socket top of hammer handle, is that there is an installation opening at its middle part at the bottom of the ∏ shape that is connected with tup below it; In the middle of at the bottom of the ∏ shape perforation is arranged, be used for passing screw; Tup is that a cross sectional shape is that trapezoidal, another cross sectional shape is the solid of rectangle, and a boss is arranged at its top, and there is a screw at the boss middle part; The shape of boss is with big or small and corresponding at the bottom of the ∏ shape of hammering handle into shape, and the hammer handle is screwed with tup.

Above-mentioned hammer is making with steel, and tup is made with high chromium alloy material.

The using method of the wear-resisting quartering hammer of combined type is: among the boss of above-mentioned tup being bumped at the bottom of the ∏ shape of above-mentioned hammer handle, screw in screw with screw by perforation again, will hammer handle fixedly becomes quartering hammer with tup; The sleeve joint hole that to hammer handle again into shape is inserted in rotating shaft, and whole quartering hammer just can be worked with the rotating shaft rotation.

The wear-resisting quartering hammer of combined type of the present utility model, tup adopt wear-resisting high chromium alloy material to make, and its hardness reaches the HRC60-65 standard, and be therefore durable than original quartering hammer; Even if wearing and tearing only need to change tup, hammer is continuing to use; Hammer can Welding Repair use if any wearing and tearing.Be common 3～8 times of forging hammer, potassium steel hammer service life of the present utility model, and easy for installation, dismounting is simple, can reduce broken cost, prolong the disintegrating machine activity duration, has good economic benefit.

Description of drawings

Accompanying drawing 1 is the structural representation of the wear-resisting quartering hammer of combined type of the present utility model, and Fig. 2 is that A-A is to view.Among the figure 1 for hammer, 2 be tup, 3 be sleeve joint hole, 4 is installation opening, 5 be ∏ shape at the bottom of, 6 is to bore a hole, 7 is boss, 8 is screw, 9 is screw.

The specific embodiment

The wear-resisting quartering hammer of combined type as Fig. 1 and 2, it by hammer 1 and tup 2 forms, hammer has sleeve joint hole 3 to 1 top, is at the bottom of the ∏ shape 5 below it, and an installation opening 4 is arranged in the middle part of it; There is a perforation 65 centres at the bottom of the ∏ shape; Tup 2 is that a cross sectional shape is that trapezoidal, another cross sectional shape is the solid of rectangle, and a boss 7 is arranged at its top, and there is a screw 8 at boss 7 middle parts; The shape of boss 7 and size are with 5 corresponding at the bottom of the ∏ shape; Hammer is fixing with tup 2 usefulness screws 91.Hammer is 1 usefulness 45 ^#Steel are made, and tup 2 usefulness high chromium alloy materials are made.

The hammer of this quartering hammer is 1 height overall 230mm, 5 high 40mm at the bottom of the ∏ shape wherein, wide 110mm.Hammer the thick 50mm in 1 top 5 thick 60mm at the bottom of the ∏ shape into shape.Sleeve joint hole 3 diameter 42mm, 6 diameter 24mm bore a hole.Wide 110mm on tup 2 trapezoid cross sections, following wide 120mm, high 80mm, the square-section is 60 * 80mm.Boss 7 wide 70mm, high 20mm, thick 60mm.Screw 8 and screw 9 diameters are 20mm.

Since hammer of the present utility model 1 and tup 2 must be used, therefore hammer into shape 1 or the single-piece of tup 2 all in the utility model protection domain, produce, sell and use hammer into shape 1 or the single-piece of tup 2 also belong to abuse.
