Description

Mixed Feed Grinder

technical field

The utility model relates to an agricultural feed machine, in particular to a mixed feed pulverizer which simultaneously pulverizes coarse feeds such as corn with corn cobs, stalks, straw, straw and grass.

Background technique

At present, hammer mills and cone-disk mills are mainly used in the production of concentrated feed in domestic and foreign markets.

The main structure of the hammer mill is composed of a feed hopper, a rotor, a hammer and a sieve. The working principle of the hammer mill is that the material enters the crushing chamber from the feed port, and is crushed by the impact of the high-speed rotating hammer. The crushed material flies to the tooth plate or lining plate at a high speed, and further Shattered, then bounced back to be crushed again by the hammer. At the same time of impact and impact, the material is further pulverized by the friction and shear between the end of the hammer and the screen. During this period, most of the particles smaller than the screen hole are discharged from the crushing chamber, and the particles larger than the screen hole are the same as the newly added particles. The materials together continue to be crushed.

The cone-disc pulverizer is mainly composed of a feed hopper, a movable toothed disc rotor, a fixed toothed disc, and an annular screen. There are two rings of fixed teeth on the fixed tooth plate, the cross-section of which is flat and rectangular, and there are three rings of teeth on the movable tooth plate, whose cross section is round or flat rectangle, in order to provide crushing effect, usually the fixed tooth plate and the movable tooth plate The teeth are required to be staggered. The working principle is that the high-speed rotation of the movable toothed disc generates a strong centrifugal force field, forming a negative pressure zone in the center of the crushing chamber, so that the material is sucked from the center of the fixed and movable toothed discs, and diffuses from the center to the outside under the action of centrifugal force. The material is first crushed by the impact, shearing and friction of the inner ring rotating gear and the fixed tooth, and the linear speed of the rotating gear gradually increases from the inner ring to the outer ring, and the material is more and more crushed during the movement to the outer ring. The stronger the impact, shear, friction, collision and other effects, the finer and finer the crushing will be. Finally, the material is further pulverized under the impact and counter-impact action of the outer ring teeth and the impact ring to achieve superfineness.

The above two pulverizers are generally used for separate pulverization of concentrated feed such as corn after threshing. The production of roughage, especially stalk, is cut by a hay cutter. The hay cutter is mainly composed of a feed inlet, a feed roller, a fixed cutter, a movable cutter, and a discharge outlet. Coarse fodder such as straw, grain grass, straw, grass, etc. enters through the feed inlet, enters between the fixed cutter and the movable cutter through the feed roller, cuts the feed through the movement of the movable cutter, and then discharges it from the outlet.

The concentrated feed and roughage produced by the above equipment are then mixed by a mixer to form a mixed feed. In the past, the production of mixed feed was completed by a single machine. The functions of the equipment were relatively simple, and the production efficiency was low.

Contents of the invention

The utility model is proposed to solve the problem of single function and low production efficiency of the existing feed machinery in the market, so a mixed feed grinder suitable for small and medium-sized livestock farms is designed.

The technical solution of the present utility model is realized in this way:

A mixed feed mill, comprising a frame and a motor transmission mechanism, characterized in that it also includes a roughage feeding mechanism, a concentrated feed feeding mechanism, a cutting mechanism and a kneading and crushing mechanism, wherein the roughage mechanism is located on the upper left of the processing chamber, and the fine feed The feed feeding mechanism is located on the upper part of the processing chamber, the cutting mechanism is installed in the middle of the processing chamber, and the kneading and crushing mechanism is installed on the lower right part of the processing chamber; There is also a feed port, and there is a discharge port on the right side of the kneading and crushing mechanism.

The roughage feeding mechanism is composed of a pair of roughage feeding rollers with the same tooth shape and rotating speed, which can engage with each other, and a belt and/or chain transmission system. A fixed knife is also installed on one side of the supporting roller.

The concentrate feed mechanism is composed of a pair of concentrate feed rollers with the same tooth shape and rotating speed, which can engage with each other, and a belt and/or chain transmission system. A fixed knife is also installed under one of the feed rollers.

The cutting mechanism is composed of a moving knife and a transmission shaft, which forms a cutting motion with the aforementioned fixed knife when it rotates.

The kneading and crushing mechanism includes a pair of kneading rollers connected to the drive shaft with the same tooth profile and corresponding deflection angles that can engage with each other, a screen fixed on the frame, and a sieve that can rotate in the net. The rotary table of the hammer is composed of the rotary table which is connected with the transmission shaft.

Compared with the prior art, the advantages of the utility model are obvious, as shown in:

1. This model adopts double feeding ports and feeds separately in the radial direction. It integrates hay cutting, kneading and crushing. The production of concentrated feed and coarse feed in the mixed feed is completed through a mixed feed grinder.

2. The advanced feed roller for concentrate feed is designed, which can put corn cobs that do not need to be threshed directly from the feed inlet of concentrate feed, crushed by the feed feed roller of concentrate feed, cut off by the cutter, and enter the crushing chamber for crushing after kneading , greatly improving production efficiency.

3. The advanced kneading roller is designed to knead the cut corn stalks and other roughages first and then crush them, which improves the crushing efficiency.

4. A rubbing board is designed in the hammer crushing cavity, which also improves the crushing efficiency.
