Description

FIELD OF THE INVENTION

The conditioner-crusher refers to devices for grinding and conditioning of the original bulk product and can be used in the food industry or in feed production.

State of the art

Known roller conditioner for grain containing a frame, a pair of rollers mounted on the frame in the bearing assemblies on the axle shafts, the mechanism of the dump-blade for rotation of the rollers (see patent RU No. 442638, B02C 4/02, publ. 10.03.2005).

A disadvantage of the known technical solution is the limited functionality, only flattening the product.

A rotary crusher is known, consisting of a housing mounted on a support element with shock absorbing gaskets, a loading hopper and a loading, crushing and unloading chambers located in the cavity of the drive rotor housing, while the crushing chamber and the rotor are provided with corrugated surfaces capable of crushing the initial product ( see patent RU No. 2552958, B02C 4/10, publ. 06/10/2015).

The disadvantage of the rotary crusher is the limited functionality, only crushing the product.

The closest in technical essence is a roller device for flattening concentrated animal feed, including a solid metal body, frame, grooved rollers and a drive for their rotation (see patent RU No. 51899, V02C 4/06, publ. 10.03.2006).

The disadvantage of this roller flattening device is the high metal consumption and the limited functionality of it, only by flattening the product, controlling the crushing process.

Disclosure of invention

The crusher conditioner consists of a frame, an engine with a drive, a rigid and durable casing, mounted on a frame with two cylindrical rollers with corrugated surfaces fixed inside the casing with the possibility of rotation, and a loading hopper, and in the casing symmetrically fixed with limited adjustment of position and interactions with the rollers are gear elements, the axis of the rollers being provided with gears meshing with each other, and the drive is arranged to organize the reverse rotation of the rollers.

The crusher conditioner allows both crushing and flattening the crushed material due to the rotation of the rollers which are engaged with each other by gear elements interacting with their corrugated surfaces with the original product during crushing or with the corrugated surfaces of the crusher body during crushing, without an increased content of powdery fractions, easy to assemble and disassemble, the least metal consuming, allows you to adjust the position of gear elements with grooved surfaces in two directions to increase efficiency .

Brief Description of the Drawings

In FIG. 1 shows a general view of a crusher-conditioner;

in FIG. 2 shows a general view of a crusher-conditioner with a cut during conditioning;

in FIG. 3 shows a general view of a crusher-conditioner with a cut during crushing;

in FIG. 4 shows an installation fragment of a work item.

The implementation of the invention

The conditioner-crusher 1 consists of a frame 2, a casing 3 fixed on it, a feed hopper 4, in which there are three gates for feeding the crushed material into the crushing zone 5, 6 or conditioning 7, and, accordingly, crushing 8, 9 and conditioning 10 chambers, and unloading 11 chambers, while crushing chambers 8, 9 and two rollers 12, 13 with gear elements 14, 15 are provided with corrugated surfaces 16, 17, 18 and 19, respectively, made with the possibility of crushing the initial product and limited regulation of their position as on the surface of the casing 3 way moving the longitudinal element 20 in the elliptical slot 21 and securing it with bolts 22, and in the radial direction by installing washers 23, and the axis of the rollers 24, 25 are equipped with gears 26, 27 in engagement with each other, and the drive 28 is arranged to reverse the rotation of the rollers 12, 13 by means of a control panel 29, changing the polarity of the phases of the current.

The process of loading the original product, its transportation, processing into crushed material and its removal are shown by arrows.

The conditioner crusher works as follows.

The drive 28 carries out the movement of one of the rollers 12 or 13, which are engaged with each other by the gear elements 14, 15, as a result of which they rotate simultaneously, depending on the direction controlled by the control panel 29 due to a change in the polarity of the current, flattening will occur or product crushing.

When flattening

When the gate 7 is opened for flattening and simultaneously closed the gate 5 and 6 and the rollers 12, 13 are rotated in the same direction to each other (main arrow), meshing with each other by gear elements 14, 15, as shown in FIG. 2, interacting with their corrugated surfaces 18, 19 with the original product, it is captured and rolled up to obtain a rolled product 30.

When crushing

When the gate is closed 7, the opening of two gates 5, 6 for crushing and rotation of the rollers 12, 13, interconnected by gear elements 14, 15, in the opposite direction to each other (dashed arrow) by changing the polarity of the current, through the control panel 29 as shown in FIG. 2, interacting with their corrugated surfaces 18, 19 with the original product, it is captured and moved before interacting with the corrugated surfaces 16, 17 of the crusher body 3, crushing the initial product to obtain a fractional product 31. The grinding size is adjusted by moving the longitudinal element 20 to the surface of the casing 3 in the elliptical slot 21 and securing with bolts 2 and in the radial direction by installing washers 23.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- provides the ability to perform conditioning or crushing with a universal device;

- provides control of the process of crushing the material in order to change the grinding size, by adjusting the position of the gear element with a corrugated surface, which increases the efficiency of its work;

- the design of the crusher-conditioner allows for its transportation compactly disassembled;

- simplifies the interchangeability of the working bodies and their adjustment to achieve the best result.
