Description

Technical Field

[0001] The invention belongs to the technical field of kneading machine equipment, in particular to a forage kneading processing device. Background Art

[0002] Forage is the foundation for the development of livestock and poultry production, especially the production of herbivorous livestock. Forage contains not only various nutrients necessary for livestock, but also crude fiber, which is particularly important for maintaining the health of ruminant livestock, and which cannot be replaced by grain and other feeds. At present, during the drying, storage and transportation of forage after harvest, untreated forage is prone to mildew and nutrient loss, and ordinary forage processing methods are often inefficient and difficult to effectively improve the nutritional value of the feed. Therefore, it is often necessary to knead it to destroy the forage cell structure through physical action, promote rumen fermentation, and improve the digestibility and utilization rate of the feed;

[0003] In the prior art, such as the invention patent with publication number CN108142965A, a rotating rod is mainly used to knead the agricultural and forage grass well, thereby ensuring the processing efficiency of the agricultural and forage grass; however, the simple rotating rod structure lacks sufficient kneading strength, and the long fiber structure of the forage grass is not easy to be effectively interrupted, which affects the palatability of the feed and the digestion and absorption rate of the animal; and most equipment uses a single kneading process to process the forage grass, and the forage grass is prone to excessive crushing in some areas while other areas remain in large blocks, resulting in large differences in texture and size of the final product, affecting the overall quality and uniformity of the feed.

[0004] Therefore, it is necessary to provide a grass kneading processing device to solve the problems raised in the above background technology. Summary of the invention

[0049] The kneading and crushing unit 2 is installed on the machine base 1 at one side close to the transmission frame 11. A hopper 13 is fixed on the kneading and crushing unit 2. The transmission frame 11 sends the evenly spread grass into the kneading and crushing unit 2 through the hopper 13 for preliminary chopping and crushing.

[0050] The air separation mechanism 3 is arranged in the machine base 1 on one side of the kneading and crushing unit 2, and the discharge end of the kneading and crushing unit 2 is connected to the air separation mechanism 3; wherein, wind separation can effectively remove dust, fine leaves, light impurities, etc. generated during the kneading process, improve the purity of the feed, and at the same time can realize the classification of the forage fragments according to the particle size; and the forage fragments after air separation are looser and more uniform, which is conducive to the uniform penetration of heat and airflow in the subsequent drying process, thereby improving the drying efficiency;

[0051] There are multiple kneading mechanisms 4 arranged in an array, each of which is fixed in the machine base 1 and located on one side of the air selection mechanism 3. Each of the kneading mechanisms 4 performs differentiated processing on the forage by adopting an appropriate kneading processing mode (such as adjusting the kneading strength, time, etc.) according to the air selection condition of the forage after cutting and crushing, thereby ensuring that the nutritional components of the forage are effectively retained and improving the flexibility and palatability of the forage.

[0052] In this embodiment, the kneading and crushing unit 2 includes:

[0053] The crushing seat 21 is horizontally rotatably connected to the main shaft 22 via a bearing;

[0060] There are multiple feeding channels 34, which are arranged in one-to-one correspondence with each of the kneading mechanisms 4. The feeding channels 34 are vertically distributed on the inner channel 31 and are connected to the inner channel 31 through the sorting net 33;

[0061] The air supply seat 35 is fixed outside the inner channel 31. The air supply seat 35 and the sorting net 33 are centrally symmetrically arranged on both sides of the feeding channel 34. An air hole group 36 is opened on the side wall of the inner channel 31. The air supply seat 35 is correspondingly connected to the air hole group 36.

[0062] In this embodiment, each of the sorting nets 33 is fixed in the inner channel 31 at an angle, and the angle of inclination thereof is between 10° and 25°; it has a certain material blocking effect, and is convenient for quickly sorting the cut and crushed grass;

[0063] The sorting net 33 is arranged in a gradually increasing mesh size from left to right, so that the grass fragments can be classified according to the particle size and enter the feeding channel 34 through the sorting net 33 accordingly.

[0065] In this embodiment, the kneading mechanism 4 includes:

[0066] A fixing frame 41 is provided, a silo 42 is fixed below the fixing frame 41, and a cover 43 is detachably mounted above the fixing frame 41;

[0069] A knife disc holder 47 is fixed in the material bin 42 and is located on one side of each kneading disc 45;

[0070] The driving unit 48 is disposed on the fixing frame 41 , and the output end of the driving unit 48 is connected to the rotating shaft 44 through a transmission belt for transmission.

[0071] As a preferred embodiment, the surface of the cutter disc frame 47 is provided with a plurality of sharp teeth distributed circumferentially, and the kneading disc 45 is provided with a groove on the opposite side of the cutter disc frame 47, that is to say, when the driving part 48 drives the rotating shaft 44 to rotate, the kneading disc 45 and the cutter disc frame 47 produce relative rotation, and at this time, the grass can be deeply kneaded and refined through the grooves on the kneading disc 45 and the sharp teeth on the cutter disc frame 47, which can not only continue to crush the grass, but also strengthen the destruction of the grass fiber, thereby improving the digestibility and absorption rate of the grass.

[0072] In this embodiment, the kneading disc 45 is slidably and adjustably sleeved outside the rotating shaft 44, and a mounting seat 5 corresponding to the kneading disc 45 is also fixed in the silo 42, and a shaft pressing sleeve 51 is slidably connected to one side of the mounting seat 5, and the shaft pressing sleeve 51 is slidably sleeved on the rotating shaft 44, and a positioning disc 52 is rotatably connected to one side of the kneading disc 45, and the shaft pressing sleeve 51 is connected to the positioning disc 52 through a shaft tube; that is, when the shaft pressing sleeve 51 slides axially along the rotating shaft 44, it can push the positioning disc 52 to slide synchronously through the shaft tube, and the kneading disc 45 in the rotating work generates synchronous displacement at this time, so as to adjust the distance between the kneading disc 45 and the knife disc holder 47;

[0073] The mounting seat 5 is symmetrically rotatably connected with a connecting rod 53 , one end of which is hinged to the shaft pressure sleeve 51 ; the mounting seat 5 is also provided with an electric telescopic rod 54 , the telescopic end of which is connected to the other end of the connecting rod 53 .

[0074] In this embodiment, the electric telescopic rod 54 controls the kneading disc 45 to approach or move away from the knife disc frame 47 through the axial pressure sleeve 51 under telescopic adjustment, thereby effectively controlling the kneading processing intensity. In particular, each kneading mechanism 4 can enhance the processing intensity according to the actual forage sorting situation, thereby more thoroughly cutting and crushing the forage or reducing the kneading work intensity, maintaining a certain fiber structure of the forage, and being able to adapt to different types of forage and different processing requirements to ensure processing quality and efficiency.

[0075] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
