Abstract

The utility model discloses a vertical shaft hammer type crusher which comprises a cylinder, an upper cover, a lower cover, a feeding hopper at the upper end of the cylinder, a discharging hopper at the lower end of the cylinder, a shaft arranged at position of the middle axis of the cylinder, wherein, the upper cover is provided with a sealing cover, a bearing and a bearing cover; an upper part of the shaft passes through the bearing on the upper cover and is connected with a pulley; the lower end of the shaft matches with the bearing on the lower cover; the shaft is connected with a plurality of discs through keys; the disc is radially uniformly distributed with a plurality of holes; each two discs are combined into a pair; the circumference of each pair of disc is connected with a hammerhead. The axial distance between two pairs of adjacent discs is different, and the distance from the discharging hopper is closer, and the distance between two pairs of adjacent discs is smaller. Hammerheads on two pairs of adjacent discs are alternately distributed along the direction of circumference. Hammerheads on two pairs of adjacent discs of the utility model have different distributing angles along the direction of circumference, so a crushing cavity can be fully used; the section shape of the hammerhead is a diamond, and adjacent surfaces are fillet transited, thereby guaranteeing hammering effect of the hammerhead to materials.

Description

Vertical-spindle hammer crusher

Technical field

The utility model relates to a kind of disintegrating machine, particularly a kind of coarse crushing and broken disintegrating machine of fine powder that is applicable to hard ore etc. in other such as lime stone, flyash, gangue, iron ore, sandstone, gypsum, slag, lump coal.

Background technology

Existing vertical shaft crusher structurally has the following disadvantages:

1. the gap between hammer is bigger in the disintegrating machine, and crusher chamber can not make full use of;

2. material is in the bottom of crusher chamber, and blanking is very fast, and the hammering rate reduces, and hammering energy is failed corresponding increase, causes whole crushing effect to be difficult to abundant assurance;

3. to be shaped as circle (as shown in Figure 6) not very good to the hammer effect of material for the section structure of tup.

The utility model content

In order to overcome defective of the prior art, the utility model provides a kind of simple in structure, energy consumption is low, crushing effect is good vertical-spindle hammer crusher.

To achieve these goals, the technical solution of the utility model is to realize like this, a kind of vertical-spindle hammer crusher, comprise cylindrical shell, be positioned at the feed hopper that is provided with on the loam cake on cylindrical shell top, the lower cover that is positioned at the cylindrical shell bottom, the cylinder top cover, the discharge bucket that the cylindrical shell lower cover is provided with below, the rotating shaft that is loaded on position, cylindrical shell axis, on cover seal cover, bearing and bearing cap be housed, the top of described rotating shaft passes the bearing that covers and is connected with belt pulley; Under cover seal cover and bearing be housed, match with the bearing that covers down in the lower end of rotating shaft; Described rotating shaft is connected with a plurality of disks by key, and each disk is being evenly equipped with a plurality of holes in the radial direction, and per two disks partner, and are connected tup by bearing pin with pin on the circumference of every pair of disk.

The disk that connects in the described rotating shaft is eight, forms four pairs; Each disk is being evenly equipped with 12 holes in the radial direction.

The section configuration of described tup is a rhombus, and the head of tup is an arc surface, and each adjacently situated surfaces is a round-corner transition.

Described tup evenly distributes along the circumference of disk, and the tup on adjacent two pairs of disks is interspersed in a circumferential direction.

Be connected with three to six tups on described every pair of disk.

Axial distance difference between described adjacent two pairs of disks, near more apart from discharge bucket, the distance between adjacent two pairs of disks is more little.

On the excircle of described rotating shaft spacer is set, the axial distance between per two pairs of disks is regulated by spacer, to guarantee each to the axial distance difference between the disk, disk is fixed on the spacer by packing ring and round nut.

Described barrel wall is provided with the detection service ports, and the monitoring service ports is opened and closed by door and keeper.

As preferably, be connected with liner plate with bolt on the inwall of described cylindrical shell.

Compared with prior art, the beneficial effects of the utility model are:

1, crushing effect is difficult to the fully problem of assurance to the utility model in the prior art because each to the axial distance difference between the disk, has therefore solved.

2, since adjacent two pairs of disks on tup distribution straggly in a circumferential direction, so the cylindrical shell cavity in material can both be broken, solved the problem that crusher chamber can not be utilized fully in the prior art.

3, because the section configuration of tup is a rhombus, and each adjacently situated surfaces is round-corner transition, thereby guaranteed the hammer effect of tup to material.
