Abstract

The utility model discloses a pulverizer, which belongs to the field of feed processing equipment. It includes a crushing chamber, a main shaft, a driving motor, a blade group, an inlet hopper and an outlet hopper. The inlet hopper is installed above the crushing chamber, the outlet hopper is installed below, and the blade group is installed on the main shaft. One end of the main shaft is connected to the driving motor, and the other One end passes through the crushing chamber; the positions of the feed hopper and the discharge hopper are staggered, and the blade set includes multiple blades, which are installed at intervals along the axial direction of the main shaft, and the adjacent two blades are staggered from each other; the adjacent blades are connected Cross-cut knife, the sides of the cross-cut knife are serrated. The staggered blades and cross-cutting knives cut and hit the material in turn, and the material can be stirred while cutting and hitting the material. Combined with the staggered setting of the feeding hopper and the discharging hopper, it effectively prolongs the cutting and hitting of the material. Time, effectively improve the crushing effect and efficiency.

Description

grinder

technical field

The utility model relates to a grinder, in particular to a grinder with high crushing efficiency and good effect, which belongs to the field of feed processing equipment.

Background technique

The pulverizer is a machine that crushes large-sized solid raw materials to the required size, and is a common feed production equipment. Due to the different degrees of humidity in the material, the material is easy to agglomerate during the pulverization process, which affects the pulverization effect. At the same time, the existing pulverizers have knives, so they cannot cut the materials in turn and hit them in all directions, which affects the final pulverization effect.

Utility model content

The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a pulverizer with high crushing efficiency and good effect.

In order to solve the above technical problems, the pulverizer provided by the utility model includes a crushing chamber, a main shaft, a drive motor, a blade set, a feed hopper and a discharge hopper, the feed hopper is installed above the crushing chamber, and the discharge hopper is installed below, The blade set is installed on the main shaft, one end of the main shaft is connected with the drive motor, and the other end passes through the crushing chamber; the positions of the feeding hopper and the output hopper are staggered, and the blade set includes multiple blades, and the multiple blades are arranged along the axial direction of the main shaft Installed at intervals, two adjacent blades are staggered from each other; a cross-cutting knife is connected between adjacent blades, and the two sides of the cross-cutting knife are serrated.

The beneficial effect of the utility model lies in that: the blades and the cross-cutters arranged in a staggered manner cut and hit the materials in turn, and the materials can be stirred while cutting and hitting the materials. The cutting and hitting time of the material is prolonged, and the crushing effect and efficiency are effectively improved.

As an improvement, the crushing chamber is covered with a jacket, and a heating device is provided between the jacket and the crushing chamber, so that the materials can be heated during the crushing process to prevent agglomeration and further improve the crushing effect and efficiency

As an improvement, the crushing chamber is provided with an air inlet, and dry gas can be added during crushing to remove moisture in the material.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in FIG. 1 , the pulverizer of the present invention includes a pulverizing chamber 1 , a main shaft 4 , a drive motor 2 , a blade set, a feed hopper 5 and a discharge hopper 6 . The periphery of the crushing chamber 1 is covered with a jacket 9 , and a common heating device is provided between the jacket 9 and the crushing chamber 1 . The driving motor 2 is connected to one end of the main shaft 4 through a coupling 12 , and the other end of the main shaft 4 passes through the crushing chamber 1 and is connected to the bearing 7 . Above the crushing chamber 1 is provided a feed hopper 5 and an air inlet 10, the feed hopper 5 is used for entering various materials, and the air inlet 10 is used for adding dry gas during the crushing process to remove moisture from the materials. A hopper 6 is arranged above the crushing chamber 1 .

The blade group is installed on the main shaft 4 and is located in the crushing chamber 1 . As shown in Figure 2, the blade set includes a plurality of blades 3, which are installed at intervals along the axial direction of the main shaft 4, and two adjacent blades 3 are staggered from each other, and the staggered angles are all 90°.

As shown in Figure 3, a cross-cutting knife 8 is connected between adjacent blades 3, and serrations 11 are arranged on both lateral sides of the cross-cutting knife 8, so as to cut and strike various materials horizontally during the crushing process, and improve Shatter effect.

The above-mentioned embodiment only expresses one implementation mode of the present utility model, and its description should not be understood as limiting the patent scope of the present utility model. It should be pointed out that those skilled in the art can make several improvements without departing from the concept of the utility model, and these should fall within the scope of protection of the utility model.
