Description

Technical Field

[0001] The present invention relates to the technical field of feed, and in particular to a method for producing protein feed by using a processing device. Background Art

[0002] Protein is an indispensable ingredient in animal feed. In addition, protein is easy for animals to absorb and utilize, stimulating growth and reproduction to varying degrees. It cannot be replaced by other nutrients. Lack of protein in feed can easily lead to illness, malnutrition, and even death.

[0003] At present, most feeds use beans for protein supplementation, but soybeans are basically imported from abroad, which increases the cost of feed. At present, most feeds use plant protein to increase the protein content of feed. For example, in the prior art, CN02110721339.0 discloses a paper mulberry feed and a preparation method thereof. The raw materials of the paper mulberry feed include, by mass percentage: 40% to 60% paper mulberry leaves, 5% to 25% corn flour, 5% to 10% soybean meal, 8% to 15% bran, 5% stone powder, 5% premix, 2% enzyme preparation, and 3% to 10% beer. The paper mulberry feed efficiently utilizes the protein rich in paper mulberry and reduces the amount of feed grain. The technology discloses the use of paper mulberry as feed, but does not specifically disclose how to process paper mulberry to release protein.

[0004] In addition, when the leaves of the paper mulberry tree are used for feed processing, they are crushed by hammering with rotating blades, and the crushed particles are relatively large. To a certain extent, they cannot be directly put into use for processing. Summary of the invention

The mounting casing 20 is a cavity structure, forming a crushing chamber 20a and a feed port 20b and a discharge port 20c connected to the crushing chamber 20a. Two mounting bearings are arranged on opposite sides of the mounting casing 20, and the opposite ends of the drive shaft 32 are respectively inserted into the bearing holes of the mounting bearings.

[0099] The driving member 31 of the crushing assembly (not shown) includes a driving motor 311, a driving wheel 312, a driven wheel 313 and a transmission belt, wherein the driving motor 311 is fixed to the frame 10 by means of screws and other structures, and is spaced apart from the mounting housing 20, the driving wheel 312 is transmission-connected to the output shaft of the driving motor 311, the driven wheel 313 is sleeved on one end of the driving shaft 32, and the transmission belt connects the driving wheel 312 and the driven wheel 313.

The end of the curved knife 343 is inclined toward the side of the discharge port 20c, which can delay the time that the woody raw materials stay in the crushing chamber 20a, thereby improving the crushing effect.

[0101] In the present application, the woody raw material is put into the crushing chamber 20a from the feed port 20b, and the driving member 31 drives the driving shaft 32 to rotate, so that multiple material baffles 33 and multiple moving knife groups 34 rotate in the crushing chamber 20a, and the moving knife groups 34 continuously strike the woody raw material to crush it. During the striking process, since multiple fixed knife edges 41 are provided in the crushing chamber 20a, as the woody raw material rotates and is crushed, the multiple fixed knife edges 41 can also react to the woody raw material at the same time. In this way, without increasing the power or expanding the body of the crushing chamber 20a, the woody raw material is crushed more completely and delicately, and the crushing effect is better.

[0102] Further, the fixed blade assembly includes a plurality of connecting members (not shown), which may be screws or pins. The fixed blade edge 41 is provided with a plurality of connecting holes, and the side wall of the crushing chamber 20a is provided with a plurality of mounting holes. Correspondingly, the connecting holes and the mounting holes are correspondingly provided as screw holes or pin holes, and the connecting members are passed through the connecting holes and the mounting holes to connect the fixed blade edge 41 and the mounting housing 20. In the present application, the cross section of the fixed blade edge 41 is rectangular or triangular, and it is made of a metal profile, and is provided with connecting holes through mechanical processing. The fixed blade edge 41 and the mounting housing 20 are connected by the connecting members, and the connection is stable and easy to disassemble and assemble. Of course, the fixed blade edge may also be integrally formed with the mounting housing 20, or welded to the mounting housing 20, which is not specifically limited here.

[0103] Furthermore, the movable knife group 34 also includes a fastening screw (not shown in the figure), and the material blocking plate 33 is provided with a limiting hole passing through its opposite side surfaces, and the diameter of the limiting hole is adapted to the rod diameter of the mounting rod 341, so that the mounting rod 341 can be passed through the multiple limiting holes on multiple material blocking plates 33, and the opposite ends of the mounting rod 341 are provided with fastening threaded holes through mechanical processing, and two fastening screws are connected to the fastening threaded holes and abut against the surface of the material blocking plate 33 to fix the mounting rod 341 and the material blocking plate 33.

[0104] In one embodiment of the present invention, the side wall of the crushing chamber 20a is also provided with a material control rib 21, and the material control rib 21 is provided adjacent to one side of the discharge port 20c. In the present application, the material control rib 21 is used to stop the woody raw materials with larger particle sizes after crushing, so that they can continue to be crushed. By providing the material control rib 21, the crushing effect of the woody feed crushing structure 100 can be further improved.

[0105] Furthermore, the crushing assembly also includes an impeller 35, which is connected to the drive shaft 32 and corresponds to the discharge port 20c. When the impeller 35 rotates, a wind flow is formed in the crushing chamber 20a, and the wind flow can guide the crushed woody raw material from the feed port 20b to the discharge port 20c to complete the discharge of the woody raw material. In the present application, the impeller 35 is connected to the drive shaft 32, and there is no need to set up other driving structures, so that the structure of the woody feed crushing structure 100 is simpler.

[0106] In the present invention, the feed port 20b is set in a flared shape away from the side of the mounting housing 20 to facilitate the user to put the woody material into it; the mounting housing 20 includes a magnet 22, which is arranged at the discharge port 20c to absorb the metal material therein when the woody material is put in to prevent the metal material from damaging the equipment.

[0107] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
