Description

Grass Grinder

technical field

The utility model relates to the technical field of green fodder cutting equipment, in particular to a grass grinder.

Background technique

Forage is divided into dry feed and green feed, mainly high-quality forage and crop straw. Green feed is favored by farmers because of its good palatability and high nutritional value. However, due to factors such as short silage harvesting period, low level of mechanical equipment, and high processing costs, a considerable part of green fodder is incinerated, or moldy and rotted, which cannot be effectively used, resulting in serious waste. The annual supply of forage can only meet 70% of the demand. . Green fodder mechanical processing technology is to use machinery to cut, crush, knead, granulate and other different processing methods for pasture or crop straw, so as to facilitate transportation, storage, and improve the feed intake rate of cattle and sheep and the utilization rate of forage. The green fodder after mechanical processing has good palatability, high feed intake rate, good digestion and absorption, and high nutritional value. Adding processed high-quality forage to the feed of pigs, chickens and other livestock can replace 30% of the concentrate, saving a lot of grain and reducing costs.

In the prior art, chopping equipment is often used for processing feed such as forage grass, such as the patent "small green fodder grinder 200820028245.5", which discloses a small green fodder grinder, including a small motor 2 fixedly installed on the frame 1, a feeder The hopper 3 and the guillotine cutting box are characterized in that: the guillotine cutting box is a thin box with a front side that can be opened and closed, and the back panel 6 of the box is fixed on the frame 1, and the box body There is an opening at the bottom, which is the discharge port 7. The motor shaft extends into the guillotine cutting box from the central hole of the back plate 6. The guillotine blade 4 is installed on the motor shaft. The lower end of the feeding hopper 3 is connected to the box. The feed port 31 on the body rear back plate 6 is connected.

The equipment has low power consumption, simple structure, and flexible movement. However, during its processing, the coarse fiber green feed is only chopped once, which cannot meet the requirements of mixed feeding with other feed. At the same time, the feed port needs to be manually fed by the operator. , high risk, high labor intensity, the crushing degree of green fodder can only be judged by the experience of the operator, and cannot be controlled automatically, which affects the uniformity of crushing.

To sum up, in order to achieve high-quality crushing of crude fiber green feed, it is necessary to ensure that the particle size meets the requirements of mixing with other feeds during the crushing process, and at the same time, it cannot cause excessive loss of liquid in the green feed, because more trace elements in the green feed are contained. In the liquid, the nutrition of green fodder is guaranteed.
