Description

Technical Field

[0001] The invention relates to the technical field of feed production, in particular to a grain grinding device for feed production. Background Art

[0002] Feed is a general term for food for animals raised by all people. In a narrower sense, general feed mainly refers to the food for animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, and feed additives.

[0003] During the production process of feed, the raw materials need to be ground to reduce their volume and facilitate digestion and absorption by livestock. At present, most grain grinding devices will have some qualified grain particles and some unqualified grain particles during the grinding process. Usually, a filter screen is used to screen the ground grain particles. However, when most grinding devices are in use, since no corresponding circulation device is set, unqualified grain particles accumulate on the filter screen, which easily causes the filter screen to be blocked, thereby affecting the discharge efficiency. Moreover, when most grain grinding devices are in use, the raw materials are usually poured into the grinding device at one time, thereby increasing the burden on the grinding device, causing the grinding device to be in a high-load operation state, and affecting the service life of the grinding device.

[0052] Then, the second vertical rod 416 is driven to rotate by the rotation of the second connecting rod 407, and the cam 417 is driven to rotate by the rotation of the second vertical rod 416. At this time, the cam 417 rotates half a circle, so that the convex point of the cam 417 contacts the moving frame 415, and the moving frame 415 is pushed to move in the direction of the first connecting head 130, thereby driving the moving rod 418 to move outward, and the second connecting head 420 is driven to move by the movement of the moving rod 418, so that the second connecting head 420 and the first connecting head 130 are meshed. At this time, the first bevel gear 121 can be driven to rotate by the rotation of the first connecting rod 119, and the fourth bevel gear 414 is rotated by the rotation of the first bevel gear 121 The fixed rod 413 is driven to rotate by the rotation of the fourth bevel gear 414, the movable rod 418 is driven to rotate by the rotation of the fixed rod 413, the second connecting head 420 is driven to rotate by the rotation of the movable rod 418, the first connecting head 130 is driven to rotate by the rotation of the second connecting head 420, the cross bar 123 is driven to rotate by the rotation of the first connecting head 130, the feed roller 303 is driven to rotate by the rotation of the cross bar 123, the raw material is fed by the rotation of the feed roller 303, the raw material is moved to the upper surface of the lower grinding disc 103 through the discharge box 302 and the feed pipe 106, and the raw material is crushed by contact with the upper grinding disc 102 and the lower grinding disc 103;

[0053] Finally, the crushed raw material leaks out from the outer circle of the lower grinding disc 103 under the action of centrifugal force and falls onto the filter screen 112. The crushed raw material is screened by the filter screen 112, and the rotation of the lower grinding disc 103 drives the push rod 110 to make a circular motion. At this time, the contact between the push rod 110 and the filter screen 112 causes the filter screen 112 to vibrate slightly, thereby accelerating the screening efficiency. At the same time, unqualified grain particles slide through the slope of the filter screen 112 to the vicinity of the inner wall of the shell 101, and enter the interlayer of the shell 101 through the feed groove on the inner wall of the shell 101, thereby moving to the rotating rail 501. The unqualified grain particles are driven to move upward by the rotation of the rotating rail 501, so that the unqualified grain particles move along the track to the guide plate 104, slide into the inside of the guide pipe 105 through the slope of the guide plate 104, and re-enter the lower grinding disc 103 through the guide pipe 105 for secondary grinding.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
