Abstract

PROBLEM TO BE SOLVED: To easily execute the pulverization processing of concrete waste, etc., by fitting a pair of large and small pulverizing wheels where pulverizing teeth are projectedly provided inside a dipper are a prescribed interval, permitting the pulverizing teeth of the large pulverizing wheel to be large and coarse, permitting those of the small wheel to be small and dense and forming the guide walls of a pulverized object along the both pulverizing wheels. SOLUTION: In a backet mainbody 1, a lower part is gradually made to be narrow and the discharge space 2 of pulverized refuses is opened in a bottom. Within the pair of large and small pulverizing wheels 3 and 4, the large one 3 is pivotally attached to the almost intermediate position of the backet mainbody 1 by a rotary shaft 5 and the small one 4 is pivotally attached by the rotary shaft 6 just under the large one with a prescribed interval. The comparatively large and coarse pulverizing teeth 7 are projectedly provided in the large pulverizing wheel 3 and the multiple and small pulverizing teeth 8 are projectedly provided in the small one 4. The guide walls 10 and 11 of the pulverized object are provided in the left and the right on the inner surface of the backet mainbody 1. Thus, the pulverized object is repeatedly broken by plural pulverizing operations inside the backet mainbody 1 so as to be pulverized into small pieces and pulverization is efficiently executed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing machine provided with a function of crushing and treating concrete waste generated when a building is dismantled by a scooper such as a shovel or a bucket attached to the tip of a turning arm of a civil engineering machine. Things.

[0002]

It is an object of the present invention to provide a crusher capable of easily crushing waste concrete.

[0003]

The means of the present invention are as follows.

(1) A pair of crushing wheels, which are provided with crushing teeth of waste material such as waste concrete debris, are rotatably mounted at required intervals in a scooping device such as a shovel or a bucket mounted on a tip of a turning arm of a civil engineering machine. Of the two crushing wheels, the crushing teeth protruding around the crushing wheel at the front position are large and coarse, and the crushing teeth of the crushing wheel at the rear position are small and densely projecting, guiding crushed material along both crushing wheels A wall is formed, and an outlet space is provided at the end of the scooping device.

(2) The crush wheel at the front position having large crushing teeth is eccentric with respect to the small crush wheel at the rear position.

(3) An adjusting plate for adjusting the distance between the inner wall of the scooping device such as a shovel and a bucket and the crushing wheel at the rear position is provided on the wall surface.

(4) A small hole for dropping fine crushed material is appropriately opened on the inner wall surface of the scooping device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in FIG. 1, reference numeral 1 denotes a bucket body having a gradually narrowing lower part, and has an opening for a discharge space 2 for crushed debris at the lower bottom. Reference numerals 3 and 4 denote a pair of large and small crushing gear wheels. The large crushing wheel 3 is pivotally connected to a substantially intermediate portion of the bucket body 1 by a rotating shaft 5, and the small crushing wheel 4 is rotated by a rotating shaft 6 directly below the bucket at a required interval. To pivot. The large crushing wheel 3 is provided with relatively large and coarse crushing teeth 7, and the small crushing wheel 4 is provided with a large number of small crushing teeth 8 protruding densely. 11 are provided on the left and right. Next, in the example of FIG. 3, the guide wall is provided only on one side of the bucket body and the guide plate 13 is provided.
The crushed material is guided to one guide wall 10 by being guided to the upper end of the opening of the bucket body 1 and crushed between the guide wall 10 and the large and small crushing wheels 3 and 4. The crushing wheels 3 and 4 do not need to have different diameters as in the illustrated embodiment. The size of the teeth of the crushing wheel having the same diameter is changed, and the teeth of the rear crushing wheel are made smaller and protrude densely. Is also good.

Next, in the embodiment shown in FIGS. 4 to 7, the large crushing wheel 3 is eccentric with respect to the small crushing wheel 4 and the distance between the scooping device inner wall surfaces 22, 23 and the large crushing wheel 3 is varied by rotation. The crushing state is changed.

As shown in FIG. 6, the large crushing wheel 3 has side walls 22,
The small crushing wheel 4 incorporates a small motor 26 into the small crushing wheel 4 as shown in FIG.

Further, the one shown in FIG. 5 is such that the distance between the inner wall surfaces 22, 23 of the scooping device 1 and the small crushing wheel 4 is adjustable so that the crushing and falling can be performed under any favorable condition according to the crushing state. Then, an adjustment plate 28 is pivotally attached to the inner wall surface 23 and adjusted with an adjustment bolt 29. Therefore, the adjustment bolt 29 is penetrated through the guide wall 11 and the nut 30 is screwed. As shown in FIG. 5, in the present invention, a large number of small holes 15 are formed in the inner wall surfaces 12 and 13 of the scooping device 1, and fine crushed particles are dropped from the small holes 15.

[0012]

According to the present invention, concrete lumps are first crushed by rotation of the leading rotary shaft 5 and the toothed wheel 3 and the guide wall 1 are rotated.
The crushed material is crushed in the bucket main body 1 because the crushed material is crushed between 0 and 11 and subsequently crushed by the two tooth wheels and also in the space between the tooth wheel and the guide wall with the rotation of the crushing wheel 4 of the lower rotating shaft 6. The operation of being hurt multiple times is repeated, and finally, it is crushed into a small size and falls, and can be efficiently crushed. In addition, since the large crushing wheel 3 and the small crushing wheel 4 are eccentric, the crushing state is changed, and the crushing action is remarkably promoted by adjusting the distance between the small crushing wheel 4 and the inner wall surface and opening the small holes 15. There is an effect that can be done.
