Description

Hopper structure of cone crusher {HOPPER STRUCTURE OF CONE CRUSHER}

The present invention relates to the hopper structure of the cone crusher, and in particular, by allowing the upper and lower movable structure of the dual structure of the upper and lower hopper and to form the bottom surface of the lower hopper horizontally, to minimize the impact during the input process of aggregate In addition, the present invention relates to a hopper structure of a cone crusher whose structure has been improved to easily remove foreign substances inside the top cell.

In general, the collection process of the aggregate has a crushing process of crushing the rock using explosives such as dynamite in the place of the quarry or mine, and then crushed again to the appropriate size required by the user using a grinder.

The grinder includes a jaw crusher for crushing a relatively large mass of aggregate, and a cone crusher for crushing the aggregate crushed from the jaw crusher to a smaller size.

Here, the cone crusher will be dealt with, and its general structure is a structure in which aggregate is crushed by putting an aggregate between an eccentrically rotating cone-shaped mantle and a fixedly installed cone cave.

Typically, the cone crusher is roughly divided into C.C (Crusher Coarse) type and C.S.H (Crusher Short Head) type according to the structure and shape of the crushing chamber.

Conventional CC type cone crusher, as shown in Figure 1, the main frame 10 of the substantially cylindrical shape, the rotating shaft 20 which is accommodated inside the main frame 10 and installed so as to rotate in an eccentric state And a cone-shaped mantle core 35 and a mantle 30 coupled to the outer circumferential surface of the rotation shaft 20, a top frame 40 mounted on an upper portion of the main frame 10, and a top frame 40. Screwed to the) is roughly divided into the top shell 60 is installed with a concave 50 spaced apart from the mantle 30 by a suitable distance.

In addition, a release spring 70 is installed between the top frame 40 and the frame 10 to handle the vertical load generated during the grinding process of the aggregate.

In addition, the top cell 60 is configured such that the vertical cross section has a trapezoidal shape, and an assembling hole 62 of an appropriate size is formed for assembling and cleaning.

Distributors 80 for dispersing aggregates are provided at the upper end of the rotating shaft 20.

In addition, one side of the main frame 10 has a shape that can be coupled to the drive shaft housing 97 for providing a driving force to the rotating shaft 20, the portion for transmitting the driving force transfers the driving force from a separate power source It consists of a receiving pulley 92, a drive shaft 95 horizontally installed to interlock with the pulley 92, and a drive shaft housing 97 that surrounds the outside of the drive shaft 95 and is coupled to the frame 10.

In the conventional cone crusher having such a structure, after the aggregate is generally introduced into the crushing chamber through the hopper 300, the gap between the mantle 30 and the concave 50 is varied according to the eccentric rotation of the rotating shaft 20, aggregate After being crushed by the gap change and falling to the lower side of the crushing chamber, it is sorted according to the size through the sorting network and then transferred to the next process through a conveyor belt (not shown).

In general, the cone crusher has a characteristic that the crushing performance is variable according to the length, angle and size of the concave 50 and the mantle 30 forming the crushing chamber.

In addition, a top cell liner 61 having an appropriate inclination is coupled to a lower portion of the inner surface of the hopper 300 into which the aggregate is injected.

The top cell liner 61 prevents the impact force of the aggregate injected through the hopper 300 from being directly transmitted to the top cell 60 side, and has a function of inducing the aggregate to slide to the crushing chamber side.

2 is a view showing a coupling structure of a conventional concave, the hooks formed on the outer circumferential surface of the concave 50 is inserted into the top cell 60, respectively, the hooks by the U bolt 66 and the fastener 64 It is supported and has a structure fixed in the partition wall 65 of the top cell (60).

That is, both ends of the U bolt 66 are vertically penetrated by the fastener 64 while supporting the hook of the concave 50, and then are fastened by the nut 67, and the fastener 64 is the partition wall 65. It has a structure that is fixed in a state seated on the bottom surface.

However, the hopper and the top cell liner of the conventional cone crusher have a problem that the impact force colliding with the aggregate is directly transmitted to the top cell liner and worn out in the process of inputting the aggregate, and wastes time and cost during the replacement work.

In addition, since a lot of dust such as soil is introduced into the top cell, when replacing the concave, it is necessary to dig out the soil through the assembly hole, but this is not only difficult, but also requires a lot of time, so the whole maintenance time becomes longer. Since the downtime of the equipment is increased, there is a big disadvantage of economic loss.

The present invention was devised to solve this problem in view of the above-mentioned problems, and its purpose is to prevent the impact force from being transferred to the top cell liner side during the input of aggregate, and to easily remove foreign substances inside the top cell. To provide a hopper structure of the improved cone crusher.
