Description

Technical Field

[0001] The utility model belongs to the technical field of feed production equipment, and in particular relates to a feed mixing and dispensing device. Background Art

[0002] Feed is a general term for food for animals. In a narrower sense, feed mainly refers to 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, feed additives, etc. A feeding device is used when mixing the feed.

[0003] The feeding device mainly uses the mechanical force of the mechanical device to transport materials. Commonly used conveying devices include belt conveyors, chain conveyors, container conveyors, screw conveyors, vibrating conveyors and bucket elevators. Among them, screw conveyors are mostly used for conveying in the process of feed mixing. The screw conveyor is a rotating type of material conveying machinery without a flexible traction member. It is one of the important mechanical equipment indispensable for modern production and logistics transportation. The working principle of the screw conveyor is that the rotating spiral blades push the material to transport it. In order to adapt to different application scenarios, the input and output ends of the screw conveyor are installed at the same height or different heights.

[0004] However, the existing traditional screw conveyors are generally fixedly installed on the base, which makes it difficult to adapt to the occasions where the conveying height and angle need to be adjusted, and it is impossible to achieve the purpose of using one screw conveyor in multiple mixing production occasions; in addition, when feeding operations are performed, the material is easy to be blocked at the feed port of the screw conveyor, causing the screw conveyor to idle, affecting the normal operation of the feeding device and causing a waste of resources.

[0027] Working process:

[0028] In the actual working process, the feed hopper 9 is connected to the discharge port of the silo for storing feed raw materials, and the above connection can be made by using a hose; the feeding device is transferred to the position where the batching tank (batch container) is located, and then the hydraulic drive cylinder 2-3 is started to adjust the height of the discharge hopper 7-7. The extension of the piston rod of the hydraulic drive cylinder 2-3 can drive the upper swing frame 2-6 and the two sets of lower adjustment swing arms 2-4 to extend, thereby driving the spiral conveying structure 7 to flip upward around the pivot position of the rear pivot seat 6, and then adjusting the height of the discharge hopper 7-7 to make it suitable for the height of the feed port of the batching tank, so that the material falling from the discharge hopper 7-7 can fall into the feed port of the batching tank;

[0029] During the working process, the raw materials in the silo fall into the feed hopper 9 under the action of gravity. During the falling process, the upper feed grid 11 installed at the open end of the feed hopper 9 can perform a preliminary filtering operation on the materials to prevent the materials in a large agglomerate state from falling into the feed hopper 9. In addition, the filter plate 10 and the lower feed grid 12 in the feed hopper 9 can further play a filtering role.

[0030] When the stirring motor 8-3 is started, it can drive the stirring shaft 8-1 to rotate. The rotating stirring shaft 8-1 can drive the square sleeve and multiple groups of stirring blades 8-2 installed thereon to rotate synchronously, thereby stirring the material that falls into the feed hopper 9, so as to prevent the material from clogging the feed port 7-1 in the spiral conveying structure 7, and thereby prevent the transmission auger 7-3 in the spiral conveying structure 7 from idling and affecting the feeding operation; since the multiple groups of stirring blades 8-2 can penetrate the lower feed grid 12 during rotation, the rotating multiple groups of stirring blades 8-2 can break up the agglomerated materials trapped by the lower feed grid 12, thereby facilitating the material to enter the spiral conveying structure 7 from the feed port 7-1 to realize the feeding operation.
