Description

Technical Field

[0001] The utility model belongs to the technical field of feed additive production equipment and relates to a feed additive raw material crushing device. Background Art

[0002] New feed additives use Chinese herbal medicine as the main raw material to achieve the purpose of replacing and reducing antibiotics. They can significantly reduce the use of antibiotics or replace the use of antibiotics to optimize the disease resistance of feed. When crushing the raw materials, due to the large amount of raw materials used in large-scale production, the efficiency of traditional Chinese herbal medicine crushing (toothed disc type) equipment is difficult to meet the needs because it cannot continuously input and output materials. Utility Model Content

[0003] The purpose of the utility model is to provide a feed additive raw material crushing device in view of the above-mentioned problems existing in the existing technology. The technical problem to be solved by the utility model is how to improve the crushing efficiency.

[0004] The purpose of the utility model can be achieved through the following technical solutions: A feed additive raw material crushing device, characterized in that it includes a cylindrical crushing box and a plurality of crushing units arranged in sequence along the axis direction of the crushing box, the crushing unit includes a fixed crushing disk perpendicular to the axis of the crushing box and a rotating rod rotatably connected to the axis of the crushing disk, the crushing tooth 1 on the rotating rod, the crushing tooth 2 on the fixed crushing disk is misaligned with the crushing tooth 1, and the fixed crushing disk has a notch; each rotating rod is fixed on a drive shaft, and the drive shaft is connected to the output shaft of a motor; the crushing box is inclined at an angle of 70 to 120 degrees between the axis and the horizontal plane; the upper end of the crushing box has an inlet, and the lower end of the crushing box has an outlet.

[0005] Furthermore, from top to bottom, the notch on the fixed pulverizing disk of each pulverizing unit gradually decreases.

[0006] Furthermore, the notches on adjacent fixed comminution discs are staggered.

[0007] In essence, this crushing device is provided with a plurality of relatively independent crushing spaces. Each crushing unit crushes the material on its fixed crushing disk. The material after one crushing falls from the gap into the crushing space below, so that the material is crushed multiple times in sequence. The material after multiple crushing falls out from the bottom, thereby realizing continuous feeding and discharging.

[0008] Due to the gradual reduction of the gap size, the size of the material entering the next crushing unit can be controlled to a certain extent, thereby ensuring that the material coming out of the bottom crushing unit has the set degree of refinement. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 and Figure 2 The feed additive raw material pulverizing device shown includes a cylindrical pulverizing box 1 and a plurality of pulverizing units arranged in sequence along the axis of the pulverizing box 1. The pulverizing unit includes a fixed pulverizing disk 8 perpendicular to the axis of the pulverizing box 1 and a rotating rod 2 rotatably connected to the axis of the pulverizing disk, a pulverizing tooth 1 3 on the rotating rod 2, a pulverizing tooth 2 4 staggered with the pulverizing tooth 1 3 on the fixed pulverizing disk 8, and a notch 5 on the fixed pulverizing disk 8; each rotating rod 2 is fixed on a drive shaft, and the drive shaft is connected to the output shaft of a motor; the pulverizing box 1 is inclined at an angle of 70 to 120 degrees between the axis and the horizontal plane; the upper end of the pulverizing box 1 has an inlet 6, and the lower end of the pulverizing box 1 has an outlet 7.

[0014] From top to bottom, the notches 5 on the fixed pulverizing disks 8 of each pulverizing unit gradually decrease in size, and the notches 5 on adjacent fixed pulverizing disks 8 are staggered.

[0015] In essence, this crushing device is provided with a plurality of relatively independent crushing spaces. Each crushing unit crushes the material on its fixed crushing disk 8. The material after one crushing falls from the gap 5 into the crushing space below, so that the material is crushed multiple times in sequence, and the material after multiple crushing falls out from the bottom, thereby realizing continuous feeding and discharging.

[0016] Due to the gradual reduction in the size of the gap 5, the size of the material entering the next crushing unit can be controlled to a certain extent, thereby ensuring that the material coming out of the bottom crushing unit has a set degree of refinement.

[0017] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
