[0002] As people's living standards continue to improve, the demand for meat, poultry and eggs has increased greatly. In order to meet people's needs, the breeding industry has become increasingly prosperous, and the feed industry has also expanded. In recent years, pig, chicken and other livestock and poultry feed has developed rapidly. Grain crops are the main raw materials for feed production, especially energy-based raw materials headed by corn, which are widely used in chicken feed, especially laying hens. The particle size of the food is about 3.0mm in diameter. However, the traditional grinders on the market produce materials with too high powder content and the fineness does not meet the requirements. Too high powder content will cause waste and increase breeding costs. Summary of the invention

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0023] See also Figure 1, Figure 2 This embodiment is a feed crusher, which is composed of a machine base 1, a bottom plate 2, a reduction motor 3, a movable bevel gear 4 and a fixed bevel gear 6. The machine base 1 is a frame structure, which is provided with a leg 1-1. A circular bottom plate 2 is welded on the top of the machine base 1. The bottom plate 2 is provided with a center hole 2-1. The edge of the bottom plate 2 is processed with a plurality of circularly arranged mounting holes. The mounting holes are two types of through holes 2-2 and threaded holes 2-3. The through holes 2-2 and the threaded holes 2-3 are arranged at intervals. The bottom plate 2 is symmetrically processed with two rectangular discharge ports 2-4, and the discharge ports 2-4 are close to the edge of the bottom plate 2. A power mechanism is installed below the bottom plate 2. The power mechanism is a reduction motor 3. The motor of the reduction motor 3 is a variable frequency motor. The reducer of the reduction motor 3 is connected to the bottom plate 2 by bolts, and the output shaft of the reducer passes through the center hole 1-1 of the bottom plate 2.

[0024] A movable bevel gear 4 is provided above the bottom plate 2. The movable bevel gear 4 is conical and hollow, and is provided with a cone bottom 4-1. The outer cone surface of the movable bevel gear 4 is evenly distributed with an outer tooth structure 4-2 in the generatrix direction. The outer tooth structure 4-2 is divided into a lower ring outer tooth 4-3, a middle ring outer tooth 4-4 and an upper ring outer tooth 4-5. The middle ring outer tooth 4-4 corresponds to the lower ring outer tooth 4-3 at intervals, and the upper ring outer tooth 4-5 corresponds to the middle ring outer tooth 4-4 at intervals. A shaft sleeve 4-6 is welded at the center of the bottom surface of the cone bottom 4-1. The shaft sleeve 4-6 is connected to the output shaft of the reduction motor 3 by a key, and the reduction motor 3 drives the movable bevel gear 4 to rotate through the cone bottom 4-1. A circular rib plate 4-7 is welded to the bottom surface of the cone bottom 4-1, and 8 radial discharge wings 5 ​​are welded to the bottom surface of the cone bottom 4-1. The discharge wings 5 ​​are evenly arranged and are vertical plates located between the rib plate 4-7 and the edge of the cone bottom 4-1. The discharge wings 5 ​​cooperate with the discharge port 2-4.

[0025] The fixed bevel gear 6 is mounted on the movable bevel gear 4. The fixed bevel gear 6 is a conical cylinder structure, which includes a feed port 6-1, an upper conical cylinder portion 6-2 and a lower conical cylinder portion 6-3 from top to bottom. The feed port 6-1 is located at the top of the upper conical cylinder portion 6-2. The cone angle of the upper conical cylinder portion 6-2 is greater than the cone angle of the lower conical cylinder portion 6-3. The inner conical surface of the fixed bevel gear 6 is evenly distributed with an inner tooth structure 6-4 in the generatrix direction. The inner tooth structure 6-4 of the fixed bevel gear 6 is the same as the outer tooth structure 4-2 of the movable bevel gear 4. A gap is provided between the tooth top of the inner tooth structure 6-4 and the tooth top of the outer tooth structure 4-2. A flange 7 is welded on the outside of the bottom of the fixed bevel gear 6. The circular hole 7-1 of the flange 7 corresponds to the through hole 2-2 of the bottom plate 2.

[0026] A gap adjustment mechanism 8 is provided between the circular hole 7-1 of the flange 7 and the through hole 2-2 of the base plate 2. The gap adjustment mechanism 8 is composed of an adjusting bolt 8-1, a spring 8-2, a top screw 8-3 and a locking nut 8-4. The adjusting bolt 8-1 is installed in the circular hole 7-1 of the flange 7 and the through hole 2-2 of the base plate 2. The adjusting bolt 8-1 above the flange 7 is fitted with a spring 8-2. The spring 8-2 is a compression spring. The spring 8-2 presses the flange 7 and the base plate 2 tightly. The top screw 8-3 is installed in the threaded hole 2-3 of the base plate 2. The top screw 8-3 is installed from bottom to top. The top screw 8-3 is screwed into the locking nut 8-4. The flange 7 is provided with a blind hole 7-2 that cooperates with the top screw 8-3. A certain gap is reserved between the movable bevel gear 4 and the fixed bevel gear 6. In actual operation, according to the particle size requirement of the material, the gap between the movable bevel gear 4 and the fixed bevel gear 6 is changed by the top screw 8-3 of the gap adjustment mechanism 8 and the locking nut 8-4 to meet the feed particle size requirement. The top screw 8-3 pushes the flange 7 upward, and the gap between the movable bevel gear 4 and the fixed bevel gear 6 becomes larger, otherwise the gap becomes smaller.

[0027] The working process of the present invention is as follows: the material enters from the feed port 6-1 at the top of the fixed bevel gear 6, and flows into the space between the fixed bevel gear 6 and the movable bevel gear 4 by its own weight. When the movable bevel gear 4 rotates, the material between the fixed bevel gear 6 and the movable bevel gear 4 will be crushed. The material is pushed by the tooth surface and slides down along the tooth groove. The material that is directly aligned with the discharge port 2-4 is discharged out of the machine. The material that is not aligned with the discharge port falls on the bottom plate 2. The material is pushed into the discharge port 2-4 by the discharge wing 5 rotating with the movable bevel gear 4 and discharged out of the machine. During the crushing process, since the fixed bevel gear 6 is pressed by a compression spring, if a larger particle enters, the fixed bevel gear 6 will be relatively displaced, and the gap will automatically adapt to the crushing of the large particle to avoid damage to the equipment.

[0028] The above description is only a preferred feasible embodiment of the present invention, and does not limit the scope of rights of the present invention. All equivalent structural changes made using the contents of the present invention description and drawings are included in the scope of rights of the present invention.
