Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hammer in a crusher for crushing waste materials such as garbage and steel materials.

The hammer of a crusher is constantly subjected to large impact forces as it collides with waste, so its tip, especially its striking side, is likely to wear out, and as wear progresses, the crushing efficiency of the hammer gradually decreases. Therefore, in order to crush waste with high crushing efficiency, it is necessary to frequently replace the hammer with a new one, which is very uneconomical.

In view of these points, the hammer is constructed of an arm and an impactor, and the four corners of the impactor are positioned on the striking side by changing the mounting condition of the impactor, thereby making it easy to replace the hammer with a new one. It is designed to maintain a state where it can be efficiently shredded for a long time without having to do it frequently, and also to reduce the amount of waste when it is discarded.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a cross section of a crusher, and this crusher t/i crushing drum (1

It is mainly composed of...

Next, to explain the hammer +41, which is the main part of the KN' release, with reference to Figures 2 and 3, the hammer (4) is attached to the mounting plate +
It consists of an arm (6) which is rotatably supported by the arm (6) and a striking element (7) which is detachably attached to the tip of the arm (6).

The striking element (7) has a recess f81481 in the center of both sides.
is formed and the width is gradually increased in the front and rear, and there are four corners t9+ +Cj+ tff+ on the rear left and right.
(M is formed.Furthermore, from the rear surface of the striking element (7) to the @ surface, a through hole !Jα of a size into which the tip of the arm (6) can be inserted is bored.

fill 9-throw shaft hole approximately in the center of H batting element (7), +
121d A shaft hole drilled at the tip of the arm (6).
1. The locking pin has approximately the same diameter as the old 121, and is formed as described below (
131 into each shaft hole 0 and 12, the arm (6) and the striker (7) can be attached in an image-like manner.

The above-mentioned pin (small diameter part n:4 a4 in the 13Hkr part,
A large diameter ial is formed in the center, the front surface of which is flush with the front surface of the small diameter part +tj air, and the rear surface of which protrudes rearward, and the large diameter part - is [! Almost the same as shaft hole fill 112
It forms the shape of.

Note that (141 is an electric motor that drives the rotating shaft (2).

The uninvented device has the above configuration, and now has an arm (6) and a striker (7).
To explain how to connect the arm (6), first insert the tip of the arm (6) into the through hole (1) of the striker (7), and connect the shaft hole @ of the arm (6) and the shaft hole (1) of the striker (7). 111
and insert the locking pin u3 into each shaft hole 1J11u21. When the striker (7) is then moved forward, the shaft hole at+ and the shaft hole 12 are displaced as shown in FIG.
This prevents the locking bottle αJ from falling and also connects the arm (6) and the striker (7) in an image-like manner.

In the above state, when the electric motor (rotating shaft 12 by 14) is driven, the hammers 141 +41 are held in the radial direction by their centrifugal force while the mounting plate +31 +
31..., and crushes the waste thrown into the crushing drum (21) mainly by the corner 19+ of the rotating striker (7).

During the crushing of waste as described in E, the striking side of the striking element (7) constantly collides with the waste, so that the striking element (7) is greatly worn on its striking side.

For example, as shown in Fig. 6, when the striking side corner (9) is worn to the state shown by the inclined line, first remove the locking pin q3,
Separate the striker (7) from the arm (6), then turn the striker (7) over, insert the locking pin (13) into each shaft hole [11112], and attach the striker (7) to the arm (6). ), a new corner fd+ is created on the striking side of the striker (7), which can increase crushing efficiency again.8 Next, the corner +d+ of the striker (7) shown in Fig. 6 is 2. When the crushing ability decreases due to wear as shown by the dotted chain line, first remove the striking element (7) in the same way as before, and then insert the tip of the arm (6) into the through hole 'IG from the worn side. When the arm f61 and the striker (7) are made into a negative image by the locking pin +13, a new corner ura can be provided on the striking side as shown by the solid line in FIG.

If this corner bit wears out as shown by the two-dot chain line in Fig. 7, turn the striking element (7) over in the same way as before. A new corner part can be provided on the impact side, and efficient crushing can be performed again.

And the four corners 19+ +9'+ +a t
If M is worn out, a new striker (7) is required at this point.
This means that the amount of parts to be discarded will be smaller compared to the total, making it very economical.

As described above, the uninvented hammer is constituted by an arm and a striking element that can be attached to and detached from the arm, and four corners are formed on the front, rear, left and right sides of the striking element, and each of the four corners of the striking element is disposed of as waste. This allows you to position the batting element on the hitting side without having to frequently replace it with a new batting element.
The state of efficient crushing can be maintained for a long time.

Furthermore, since the arm and the striking element can be separated and the four corners of the striking element are utilized, the amount of parts to be discarded is greatly reduced, making it economical.
