Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a distributor for uniformly supplying a crushing raw material to a cone crusher.

[0002]

2. Description of the Related Art As a known cone crusher distributor, one having a structure shown in FIG. 3 is known.

According to this conventional technique, a large crushing material input port 2'a and a small crushing material discharge port 2'b are formed above a cone crusher (not shown), and the discharge port 2'is formed.
b is provided with a rotating chute 2'inclined downward toward the periphery of the center of rotation, and a crushing material charging port 2'of this chute is provided.
A V-belt 4'hangs over a V-sheave 3'disposed on a and a rotation source 1 '(electric motor), so that a rotary chute 2'is rotatable.

Therefore, in this conventional technique, a crushing raw material (not shown) is charged into the rotary chute 2'from the crushing raw material charging port 2'a, and the crushing raw material discharge port 2'b is directed to a cone crusher (not shown). The crushing raw material is supplied and discharged, and this crushing raw material supply operation is performed while rotating the rotary chute 2 '.

[0005] Such a conventional technique has a crushing material discharge port 2'b.
It is suitable for use when crushing smaller crushing raw material (not shown), but cannot be used for crushing crushing raw material (not shown) larger than the crushing raw material discharge port 2'b, and thus the rotary chute 2 ' There is a problem that the size of the crushing raw material that can be charged into the inside is limited, and even if the crushing raw material (not shown) is smaller than the crushing raw material discharge port 2'b, it is thrown into the rotary chute 2 '. There is a problem that some of the crushed raw materials are naturally bitten while moving and tightly joined together by incorporation or the like, and the inside of the rotary chute 2'is blocked to cause clogging.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to propose a distributor for a cone crusher which has a great use benefit without being restricted by the size of the crushed raw material. .

Another object of the present invention is to propose a cone crusher distributor capable of uniformly supplying crushed raw material without causing clogging by the crushed raw material.

Still another object of the present invention is to provide a crushing raw material uniformly distributed to the corn crusher to improve the crushing efficiency and to maintain the life of the corn crusher component for a long time. .

[0009]

In order to achieve the above object, the present invention is arranged above a rotary source by obliquely connecting a crushing raw material supply plate to a rotary source arranged above a cone crusher. I propose a technical means called.

On the surface of the crushing raw material supply plate, provided is a liner having a plurality of concave grooves penetrating in the inclined direction of the supply plate and arranged in parallel at a proper interval in the rotation direction.
It is preferable to protect the crushed raw material supply plate and to minimize wear of the liner by the plurality of ridges formed between the plurality of concave grooves.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described with reference to FIGS.

The distributor A of the present invention is arranged above a well-known cone crusher B, and the crushing raw material C is evenly distributed and supplied to the crusher B to eliminate uneven wear of the cone crusher B, thereby forming a cone crusher component. The crushing efficiency of the crushing raw material C can be improved while maintaining a long life.

The general structure of the distributor A is a rotation source 1 arranged above a cone crusher B, and a crushing raw material supply plate 2 rotated by this rotation source,
A crushing raw material supply plate 2 which is inclinedly arranged above the rotation source 1;
A liner 3 provided on the entire surface of the supply plate, and a plurality of recessed grooves 4 penetrating in the inclined direction of the crushing raw material supply plate 2 on the surface of the liner and arranged in parallel in plural at appropriate intervals in the rotation direction. Composed.

The rotation source 1 is a well-known hydraulic motor and is arranged above the cone crusher B with the rotating shaft 5 facing upward. The arrangement structure is centripetal at the lower inner surface of the cone crusher 6. It is attached to the center of a plurality of brackets 7 provided in the direction, and a hydraulic hose 8 is connected to the rotary shaft 5 so as to be rotatable.

The purpose of using the hydraulic motor as the rotation source 1 is to make the main body of the distributor A compact and to provide a rotation source having a closed structure in consideration of obstacles of the rotation source 1 at the time of supplying the crushing raw material. However, if there is a rotation source with a closed structure other than the hydraulic motor, it can be used.

The crushing raw material supply plate 2 is a member used for eliminating restrictions on the size of the crushing raw material C and for preventing clogging by the crushing raw material C. The cone crushers B are connected so as to be inclined with respect to each other, and the crushing raw material C is supplied to the cone crusher B from the lower side.

The crushing raw material supply plate 2 is a rotary shaft 5 of the rotary source 1.
The upper end of the rotating column 10 which is erected on the rotating disk 9 which is rotated in conjunction with the rotating column 10 is tilted in one direction so that it can be disassembled with bolts and nuts 11 and can be exchanged when trouble occurs. Configure as possible.

The liner 3 is a member used to protect the crushed raw material supply plate 2, and is fixed to the entire surface of the supply plate 2.

The liner 3 has a plurality of recessed grooves 4 formed in parallel on its surface in advance. To allow the recessed grooves to penetrate in the inclination direction of the crushing raw material supply plate 2, the recessed grooves 4 are formed in the inclination direction of the supply plate 2. Then, the liner 3 is fixed to the surface of the supply plate 2. Thus, the plurality of concave grooves 4 are arranged in parallel with the rotation direction of the crushing raw material supply plate 2.

If a plurality of concave grooves 4 are formed in parallel on the surface of the liner 3 at appropriate intervals, a plurality of ridges 12 are formed in parallel between the concave grooves. The line prevents the liner 3 itself from being prematurely worn due to the crushed raw material C.

[0021]

As described above, according to the present invention, since the crushing raw material supply plate is obliquely connected to the rotation source and is arranged above the cone crusher, the crushing raw material is not restricted in size. The supply size range of the crushed raw material is widened, which is beneficial, and the worry of clogging caused by the raw material during the crushed raw material supply work to the corn crusher is eliminated, and the workability of uniform dispersion supply is improved.

By uniformly supplying the crushed raw material, uneven wear of the cone crusher is eliminated,
The life of cone crusher components is maintained for a long time,
The crushing raw material can be efficiently crushed, and the crushing efficiency is improved.

Further, since the liner is provided on the surface of the crushing raw material supply plate, the supply plate can be protected from the crushing raw material and the supply plate can be used for a long time.

Further, by forming a plurality of concave grooves penetrating in the inclined direction of the crushing raw material supply plate on the surface of the liner and arranging the concave grooves parallel to the rotation direction of the supply plate,
The plurality of ridges formed between the concave grooves can prevent the liner from being prematurely worn by the crushed raw material.
