Description

A chain crusher

technical field

The utility model relates to a material crushing device for agricultural anaerobic reaction pretreatment, which belongs to the technical field of anaerobic reaction pretreatment equipment.

Background technique

With the rise of agricultural anaerobic reaction, in order to make the particle size of agricultural waste meet the requirements of anaerobic reaction, it must be pulverized. Most of the material pulverizers on the market are horizontal, and many hammers are installed on the middle spindle. , The hammer blades are generally worn very quickly. If the hammer blades are not replaced in time, the required crushing effect cannot be achieved. Due to the large number of hammer blades, replacement is very time-consuming, which brings great inconvenience to the subsequent anaerobic treatment.

Utility model content

In order to solve the defects of the prior art, the purpose of the utility model is to provide a chain crusher with good crushing effect and convenient maintenance.

The technical solution of the utility model is: a chain type pulverizer, including a pulverization shaft driven by a motor, and several pulverization chains are connected to the top of the pulverization shaft, and the pulverization chains are located at the bottom of the storage cylinder, and the bottom of the storage cylinder is sealed. The lower side wall of the material storage cylinder is provided with a material outlet, the material inlet is located at the top of the material storage cylinder, and the side wall of the material storage cylinder is provided with an inspection port.

The motor drives the crushing shaft through a belt drive wheel.

The crushing chain comprises several elliptical rings which are vertically and alternately connected.

The number of crushing chains is four.

The crushing chain is fixed on the crushing shaft through the upper platen and the lower platen.

The inspection port is located on the side wall of the outer material storage cylinder facing the upper platen and the lower platen.

The beneficial effect of the utility model is that: it solves the time-consuming problem of frequent replacement of the vertical pieces of the horizontal pulverizer, and when the chain wears seriously, it is only necessary to open the inspection port to remove the old chain and replace it with a new chain; The material moves upwards in a spiral and is crushed repeatedly. The crushing effect is good and the production efficiency is improved.

detailed description

Below in conjunction with accompanying drawing 1 the utility model is described further:

A chain type pulverizer, comprising a pulverizing shaft 2 driven by a motor 1, the top of the pulverizing shaft 2 is connected with several pulverizing chains 4, the pulverizing chains 4 are located at the bottom of the storage cylinder 5, and the bottom of the storage cylinder 5 is sealed, The lower side wall of the material storage cylinder 5 is provided with a material outlet 6, the material inlet 11 is located at the top of the material storage cylinder 5, and the side wall of the material storage cylinder 5 is provided with an inspection port 7.

The motor 1 drives the crushing shaft 2 through a belt drive wheel 3 .

The crushing chain 4 includes several elliptical rings, and the elliptical rings are connected vertically and alternately.

The number of the crushing chains 4 is four.

The crushing chain 4 is fixed on the crushing shaft 2 through an upper platen 8 and a lower platen 9 .

The inspection port 7 is located on the side wall of the outer material storage cylinder 5 opposite the upper platen 8 and the lower platen 9 .

The pulverizer is located on the equipment bracket 10. The motor 1 drives the pulley to rotate and transmits the power to the pulverizing shaft 2. The four pulverizing chains 4 are connected vertically and alternately by elliptical rings. 2 are connected together, and the rotation of the crushing shaft 2 drives the crushing chain 4 to do up and down spiral circular motion, so as to achieve the purpose of crushing the material. The feed port 11, the inspection port 7 and the discharge port 6 are respectively installed on the top, the front and the right side of the material storage cylinder. The crushing chain 4 and the upper and lower pressure plates are installed at the bottom of the storage cylinder 5 with a cylindrical inner cavity, and the four crushing chains 4 are evenly distributed on the bottom of the storage cylinder 5 according to the circumferential direction. There is a layer of 4 chains at the bottom of the barrel body 5. When the crushing shaft 2 is driven by the motor to rotate at a high speed, the chain can make the material move upwards in a spiral manner, and at the same time move downwards under the influence of gravity, so that the circular movement can achieve the purpose of crushing the material. Purpose, the crushed material is discharged from the discharge port 6. When the chain is severely worn, it is only necessary to open the inspection port 7 to replace the old chain with a new one, which avoids the problem of many hammer blades of the horizontal pulverizer and time-consuming replacement.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And modification should also be regarded as the protection scope of the present utility model.
