The technical scheme of the utility model is achieved in that:

A hob assembly for straw crushing, which includes a cylindrical drum, a transverse blade, a longitudinal blade and a radial screw, a plurality of blade discs are uniformly distributed on the cylindrical drum, and the longitudinal blade passes through the radial screw Evenly and fixedly connected to the side wall of the blade disc, each of the blade discs has five longitudinal blades evenly distributed around the circumference, and the transverse blades are welded on the longitudinal blades.

In the hob assembly for straw crushing of the present invention, it also includes a feeding belt, a feeding roller and a fixed blade, the two feeding rollers are arranged side by side at the tail end of the feeding belt, and the fixed blades are arranged in parallel On one side of the feeding roller, the cylindrical roller is arranged parallel to the fixed blade.

In the hob assembly for straw crushing of the present invention, each of the longitudinal blades is fixed by three radial screws, and the three radial screws are distributed in an equilateral triangle.

In the hob assembly for crushing straw of the present invention, the longitudinal blade is wedge-shaped, and the edge of the longitudinal blade is inclined.

In the hob assembly for crushing straws of the present invention, the welding place between the transverse blade and the longitudinal blade is located below the edge of the longitudinal blade.

In the hob assembly for crushing straw of the present invention, the inclination direction of the edge of the longitudinal blade is consistent with the rotation direction of the cylindrical drum.

The hob assembly for crushing straws of the present utility model has the following beneficial effects: by arranging a horizontal blade and a longitudinal blade on the cylindrical drum, which cooperate with the fixed blade, the material can be fed evenly under the control of the feeding roller. , improve the crushing efficiency and crushing effect of straw; the longitudinal blades are fixedly connected to the blade disk by screws, which improves the replacement efficiency of the blades; the device is small in size and compact in structure, and the two-way arrangement of the blades can reduce the stress on the blades and increase the service life of the blades. It can more efficiently and quickly crush straw in two directions, and is widely used in fields such as straw treatment, livestock feed production, and rural fertilizer processing.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

As shown in Figures 1 to 2, the hob assembly for straw crushing of the present utility model includes a cylindrical drum 1, a transverse blade 2, a longitudinal blade 3 and a radial screw 4, and on the cylindrical drum 1 There are several blade discs 5 evenly distributed, and the longitudinal blades 3 are evenly fixed and connected on the side walls of the blade discs 5 by the radial screws 4, and each of the blade discs 5 is evenly distributed around the circumference with 5 pieces of the longitudinal blades. Blade 3, said transverse blade 2 is welded on said longitudinal blade 3.

Also comprise feeding belt 6, feeding roller 7 and fixed blade 8, two described feeding rollers 7 are arranged side by side on described feeding belt 6 tail ends, and described fixed blade 8 is arranged on one side of described feeding roller 7 in parallel , the cylindrical drum 1 is arranged parallel to the fixed blade 8 .

Feeding belt 6 is located at the forefront of the crushing device and is used to complete the feeding operation. Feeding rollers 7 are installed in pairs above the afterbody of the feeding belt 6 to control the orderly entry of straw raw materials. The fixed blade 8 is installed on the frame, cooperates with the vertical blade 3 and the horizontal blade 2 to pulverize the raw material. The cylindrical drum 1 is installed on the bearing of the frame, and through rotation, the complete crushing of the straw raw material is realized.

Wherein, each of the longitudinal blades 3 is fixed by three radial screws 4 , and the three radial screws 4 are distributed in an equilateral triangle, which facilitates the assembly and disassembly of the longitudinal blades 3 . The longitudinal blade 3 is wedge-shaped, and the edge of the longitudinal blade 3 is inclined, so as to better chop straw. The welding place between the transverse blade 2 and the longitudinal blade 3 is located below the edge of the longitudinal blade 3 . The inclination direction of the cutting edge of the longitudinal blade 3 is consistent with the rotation direction of the cylindrical drum 1, which can improve the cutting efficiency of the straw.

The working principle of the crushing device is: start from the feeding belt 6, send raw materials such as straw to the feeding roller 7, through the reverse rotation of a pair of feeding rollers 7, control the orderly horizontal entry of raw materials into the crushing point, and pass the input current The size of the feed roller 7 controls the rotation speed, thereby controlling the speed of straw crushing. At this time, the horizontal blade 2 and the vertical blade 3 distributed on the rotating cylindrical drum 1 will carry out the crushing operation simultaneously. For different types and specifications of straw raw materials, the number of horizontal blades 2 and vertical blades 3 can be controlled, and finally the completely crushed straw raw materials will enter the next-level device.

So far, the purpose of the invention of the utility model is accomplished.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in the Within the protection scope of the present utility model.
