A kind of pasture grinder with three crushing chambers

Abstract

The invention relates to a pasture pulverizer with three pulverizing chambers. The pasture pulverizer sequentially comprises a pre-pulverizing chamber, a tooth plate pulverizing chamber and a screen pulverizing discharging chamber. Fixed cutters are distributed on the inner wall of a lower shell body of the pre-pulverizing chamber. A feeding port is formed in an upper shell body of the pre-pulverizing chamber to be connected with a feeding hopper. Tooth plates are distributed on the inner walls of an upper shell body and a lower shell body of the tooth plate pulverizing chamber. Tooth plates are distributed on the inner wall of an upper shell body of the screen pulverizing discharging chamber, and a discharging port is formed in a lower shell body of the discharging chamber to be connected with a discharging hopper. The discharging port is provided with a screen, and the discharging hopper is connected with a draught fan. A main shaft is located in a shell and arranged in the longitudinal direction of the shell, movable cutters are distributed on the part, located in the pre-pulverizing chamber, of the main shaft, and hammer sheets are distributed on the part, located in the tooth plate pulverizing chamber and the screen pulverizing discharging chamber, of the main shaft. A three-pulverizing-chamber structure is adopted in the pasture pulverizer, after being gradually pulverized in the different pulverizing chambers, the pasture reaches the screen to be sieved, and efficient pulverizing of the pasture low in brittleness and long in fiber can be achieved.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry machinery, in particular to a grass grinder with three grinding chambers. Background technique [0002] The development of animal husbandry and the country's requirements for the recycling of farmland waste have promoted the development and application of forage processing equipment. Crushing grass can reduce the size of the grass, reduce the bulk density, increase the specific surface area, and speed up the contact reaction speed. The shredded forage can be used directly for feeding, or it can be prepared for subsequent processing. The current pulverizers have low pulverization efficiency for hay pulverization, especially for pastures with long fiber length and low brittleness, such as gramineous pastures, which are difficult to pulverize. [0003] Grass grasses, such as Leymus chinensis, have long fibers and low stiffness of stem nodes, so it is difficult for the shredder to achieve k...

AI Technical Summary

Problems solved by technology

The current pulverizers have low pulverization efficiency for hay pulverization, especially for forages with long fiber length and low brittleness, such as gramineous forages, which are difficult to pulverize

[0003] Grass grasses, such as Leymus chinensis, have long fibers and low stiffness of stem nodes, so it is difficult for the shredder to achieve knife alignment

The shredded pasture is directly thrown out, the size is large and uneven, and the crushing effect is poor. If the hammer mill is directly used for crushing, the long fibers will quickly contact the screen, and the long fibers that cannot pass the screen will hang on the screen holes, which will cause The sieve is clogged and cannot be crushed

Because the screen plane of the vertical grinder is perpendicular to the main shaft, when the fiber hangs on the screen hole, it cannot return to the crushing chamber, and there is also the problem of screen blockage
