Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of feed production, and in particular to a device for producing functional protein feed for piglets. Background Technology
[0002] Functional protein feeds refer to feed ingredients or additives that, in addition to providing basic protein nutrition, also possess specific physiological functions (such as enhancing immunity, regulating intestinal health, and anti-oxidation). These feeds are widely used in livestock, poultry, and aquaculture, improving animal production performance, enhancing health, and reducing antibiotic use. Piglets have high requirements for protein feeds, needing highly digestible ingredients with a high amino acid balance to promote rapid growth and immune system development. A typical basic formula is: corn (50%) + soybean meal (20%) + fish meal (5%) + plasma protein powder (4%) + whey powder (10%) + premix (11%), which is then mixed and used for feeding piglets.
[0003] Fermentation is carried out during the production of piglet protein feed. However, in the existing production process of bio-protein fermented feed, the fermented feed is piled up together, and the degree of fermentation inside and outside the feed pile is different, which prevents the feed from fermenting fully. During the production process, the fermentation of the feed will produce a large amount of gas, which will cause the gas pressure inside the device to be too high. Utility Model Content
[0004] In view of the problems that existing piglet protein feeds have low fermentation efficiency, different fermentation degrees inside and outside the feed pile, and gas generated during the fermentation process, which accumulates during long-term fermentation, leading to high internal pressure in the equipment and affecting the fermentation effect, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a production device for functional protein feed for piglets, which aims to achieve good fermentation effect during the production of piglet protein feed and to treat the gas generated during fermentation.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a functional protein feed production device for piglets, including a fermentation tank, wherein a stirring fermentation mechanism is fixedly installed on the inner surface of the fermentation tank, and an adaptive ventilation mechanism is connected to the outer surface of the fermentation tank.
[0007] The stirring and fermentation mechanism includes a stirring motor, the bottom of which is fixedly connected to the top of the fermentation tank. The output end of the stirring motor is fixedly mounted with a stirring shaft via a speed reducer. The bottom end of the stirring shaft passes through the fermentation tank and extends into the interior of the fermentation tank.
[0008] In a preferred embodiment of the functional protein feed production device for piglets described in this utility model, the stirring and fermentation mechanism further includes a hydraulic cylinder, the top end of which is fixedly connected to the bottom end of the stirring shaft, a hydraulic rod is fixedly installed on the output end of the hydraulic cylinder via a piston, and an equipment box is fixedly installed on the bottom end of the hydraulic rod.
[0009] In a preferred embodiment of the functional protein feed production device for piglets described in this utility model, the stirring and fermentation mechanism further includes a rotary motor, a rotating shaft is fixedly mounted on the outer surface of the rotary motor via a reducer, and a stirring plate is fixedly mounted on the outer surface of the rotating shaft.
[0010] In a preferred embodiment of the functional protein feed production device for piglets described in this utility model, the outer surface of the rotary motor is fixedly connected to the inner surface of the equipment box via a fixing frame, and both ends of the rotary shaft penetrate the equipment box and extend to the outside of the equipment box.
[0011] As a preferred embodiment of the functional protein feed production device for piglets described in this utility model, the adaptive ventilation mechanism includes ventilation pipes, one end of each of the two ventilation pipes being connected to the outer surface of the fermentation tank, a connecting block being fixedly installed on the outer surface of the ventilation pipes, an air inlet groove being provided on the inner surface of the connecting block, and an air outlet groove being provided on the inner surface of the connecting block away from the air inlet groove.
[0012] As a preferred embodiment of the functional protein feed production device for piglets described in this utility model, the adaptive ventilation mechanism further includes a first connecting frame, the outer surface of the first connecting frame being fixedly connected to the inner surface of the ventilation pipe, a first spring being fixedly installed on the right side of the first connecting frame, and a sealing piston being fixedly installed at the right end of the first spring.
[0013] As a preferred embodiment of the functional protein feed production device for piglets described in this utility model, the adaptive ventilation mechanism further includes a second connecting frame, the outer surface of which is fixedly connected to the inner surface of the ventilation pipe, a second spring fixedly installed on the left side of the second connecting frame, and the left end of the second spring fixedly connected to the right side of the sealing piston.
[0014] Compared with the prior art, the present invention has at least the following beneficial effects:
[0015] 1. This utility model improves the fermentation of feed by adding a design that allows for more thorough fermentation. Through the combined use of a stirring motor and stirring shaft with a hydraulic cylinder and hydraulic rod, the combined use of a hydraulic rod and equipment box with a rotary motor and rotary shaft, and the combined use of a rotary shaft and stirring plate with a fermentation tank, the feed inside the fermentation tank is rolled up, ensuring a consistent fermentation effect within the feed pile and avoiding the problem of inconsistent fermentation effects inside and outside the piled-up feed.
[0016] 2. This utility model incorporates a design that allows for the automatic discharge of gas during feed fermentation. This is achieved through the coordinated use of the fermentation pipe and ventilation pipe with the connecting block and air inlet slot, the air inlet and outlet slots with the sealed piston, the sealed piston with springs one and two, and springs one and two with connecting frames one and two. This design allows the gas pressure generated during fermentation to open the sealed piston, enabling the gas inside the fermentation tank to be automatically discharged. This prevents the accumulation of gas and high gas pressure inside the fermentation tank, which could negatively impact the fermentation efficiency of the feed. Attached Figure Description

[0030] During use, the stirring motor 21 drives the stirring shaft 22 to rotate, the stirring shaft 22 drives the hydraulic rod 24 to rotate via the hydraulic cylinder 23, the hydraulic rod 24 drives the equipment box 25 to rotate, the hydraulic cylinder 23 drives the equipment box 25 to move up and down via the hydraulic rod 24, and the rotating motor 26 inside the equipment box 25 drives the stirring plate 28 to rotate via the rotating shaft 27. Through the above series of operations, the stirring plate 28 can be inserted into the fermentation tank 1 to different depths and turn the feed inside out.
[0031] Example 2
[0032] Reference Figure 2 and Figure 4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the adaptive ventilation mechanism 3 includes ventilation pipes 31. The opposite ends of the two ventilation pipes 31 are connected to the outer surface of the fermentation tank 1. A connecting block 32 is fixedly installed on the outer surface of the ventilation pipes 31. An air inlet groove 33 is opened on the inner surface of the connecting block 32.
