Description

grinder

technical field

The utility model relates to a feed grinding machine, in particular to a grinding machine.

Background technique

In grain processing, some by-products, such as chaff, are often obtained. If these by-products are thrown away, they will be wasted. In order to improve economic benefits, pulverizers are often used to crush by-products such as chaff into feed. Currently, in feed processing The pulverizer used is mainly a hammer mill. Its working principle is to use a high-speed rotating hammer to crush the raw materials. When the sieve hole is small, the fine particles will form turbulent flow due to high-speed rotation, and cannot flow out of the sieve hole smoothly. Therefore, when choosing a sieve, the size of the sieve hole should not be too small, which will cause , the obtained feed particles are larger, which affects the quality of the feed. In order to obtain feed with better quality and smaller particles, people connect a fan at the outlet of the pulverizer, and use the negative pressure formed by the rotation of the fan to suck out the feed particles. In this way, a screen with a smaller sieve hole can be selected to obtain feed with finer particles. However, the pulverizer currently used generally adopts a pulley installed on the fan shaft, which is driven by a motor through a belt, so that a transmission device is added. The overall structure of the pulverizer is loose, the size is large, and the floor area is large. When the pulverizer is working, the high-speed rotating hammer will drive part of the raw materials to be thrown out from the feeding port, resulting in waste, and if the thrown out particles are large, it is easy to hurt people, and the small particles will greatly increase the working space. The dust pollutes the environment and makes the working environment extremely harsh.

Contents of the invention

The utility model mainly solves the problems of the existing pulverizers, such as complex overall structure, large size, large occupied area, part of the raw materials being thrown out from the feeding port, resulting in waste, bad working environment and the like.

In order to solve the above technical problems, the technical solution adopted by the utility model is: the pulverizer includes a casing, a rotating shaft, a screen, and a feeding hopper, the top of the casing is provided with a feeding port, and the bottom of the casing is provided with a discharge port. The rotating shaft runs through the center of the entire casing, and at least two rotating pieces are fixed on the rotating shaft, and a plurality of hammer shafts are symmetrically penetrated between the edges of the rotating pieces, and a plurality of hammer blades are hinged on the hammer shaft at intervals. The left end of the rotating shaft is connected with the rotating blade of the fan, and the air inlet of the fan is communicated with the discharge port through the suction pipe.

Preferably, a material baffle is provided on one side of the feed inlet, and the material baffle is higher than the casing on the opposite side of the feed inlet.

Therefore, the utility model has the characteristics of compact structure, small size and small footprint. After the machine is started, its rotating shaft drives the hammer to rotate at a high speed, which has a large impact on the feed, so its crushing quality is high, and it is installed in the feed port. The baffle plate on one side can effectively block the high-speed rotating feed from flying out from the feed port, so it has the advantages of good safety, high economic benefit, environmental protection, and comfortable working environment.

Description of drawings

The technical solution of the present utility model will be further specifically described below in conjunction with the accompanying drawings and specific embodiments.

Fig. 1 is a kind of preferred mode structural representation of the utility model;

Fig. 2 is a sectional view along A-A of Fig. 1 .

Detailed ways

Fig. 1 is a schematic structural view of a preferred mode of the utility model, and Fig. 2 is its A-A sectional view. As can be seen from the figure, the pulverizer is composed of a casing 1, a rotating shaft 4, a screen 2, a fan 3, a feeding hopper 5, and the like.

The feed hopper 5 is arranged on the top of the casing 1, the outlet of the feed hopper 5 is directly opposite to the feed inlet 11 on the top of the casing 1, and the bottom of the casing 1 is provided with a discharge port 12, and the rotating shaft 4 runs through the entire casing 1 center, several rotating pieces 6 are fixed on the rotating shaft 4, a plurality of hammer shafts 61 evenly run through the edges of the rotating shaft 6, and a plurality of hammers 62 are arranged in series on the hammer shaft 61, the left end of the rotating shaft 4 It is connected with the rotor blade 32 of the fan 3 , and the air inlet of the fan 3 communicates with the discharge port 12 through the suction pipe 31 . One side of the feed port 11 is provided with a baffle plate 8, which is higher than the housing on the opposite side of the feed port 11, and a belt pulley 7 is fixed at the right end of the rotating shaft 4 as a power input part. The fixed belt pulley of the right end is used as force power input part.

The left end of rotating shaft 4 is connected with the rotating blade of blower fan 3, can reduce the special-purpose transmission device of blower blower 3 like this, makes the structure of whole pulverizer compact, and external dimension is small, and floor space is little. After the air inlet of the fan 3 is connected to the discharge port 12 through the suction pipe 31, when the grinder is working, the fan 3 operates to suck air at the same time, and a negative pressure will be formed in the grinder, so that the crushed feed can pass through the screen smoothly 2. A baffle plate 8 that is higher than the shell on the opposite side of the feed port 11 is set on one side of the feed port 11, which can prevent high-speed moving feed particles from flying out of the feed port, which not only reduces waste, improves economic benefits, but also It can avoid the flying particles from hurting people and forming dust, making the working environment safe, environmentally friendly and comfortable.
