Abstract
Description
Technical Field
[0001] This utility model relates to the field of pig farming technology, and more specifically, to a pig feed fermenter. Background Technology
[0002] A pig feed fermenter is a device used to mix raw materials such as corn, soybean meal, and straw with fermentation agents and then ferment them in a suitable environment. Its core function is to control conditions such as temperature and humidity, allowing the raw materials to decompose macromolecules (such as cellulose and protein) under the action of microorganisms, transforming them into small molecule nutrients that are easily digested and absorbed by pigs. At the same time, it produces flavor substances such as organic acids, thereby improving the palatability and nutritional value of the feed.
[0003] Existing pig feed fermenters have been found to have the following issues during use:
[0004] In use, the raw materials are usually first put into the fermentation chamber through the feed pipe, and the stirring mechanism is started to mix the raw materials evenly. Then, the fermentation is promoted by adjusting the environmental parameters (such as introducing steam to raise the temperature). After the fermentation is completed, the feed is discharged from the discharge pipe. However, it has been found that it relies heavily on high-temperature steam to raise the temperature, which can only increase the temperature of the chamber in one direction and cannot actively lower the temperature. If the ambient temperature is high, heat is easily accumulated in the chamber, which can lead to excessively high temperature, exceeding the survival range of beneficial bacteria and causing the live bacteria to become inactive, thereby reducing the qualified rate of fermented feed. Therefore, it has poor practicality. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] In view of the problems existing in the prior art, this utility model provides a pig feed fermenter to solve the technical problem mentioned in the background art of the inability to quickly reduce the temperature.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a pig feed fermenter, comprising a fermentation tank, wherein the fermentation tank is provided with a first chamber, an inlet pipe is provided at the front end of the first chamber, a stirring mechanism is provided inside the first chamber, an outlet pipe is provided at the bottom of the first chamber, the fermentation tank is provided with a second chamber, and the second chamber is located above the first chamber, two sets of ventilation holes are evenly provided through the second chamber from the top of the first chamber, an adjustment mechanism is provided at the bottom of the second chamber, pressure plates are slidably connected to both sides of the bottom of the second chamber through the adjustment mechanism, and the bottoms of the two sets of pressure plates are both located above the ventilation holes of the second chamber, a reserved hole is provided at the left end of the second chamber, a ventilation pipe is provided in the reserved hole of the second chamber, a cooling fan is provided at the right end of the inner side of the ventilation pipe, and a filter assembly is provided at the left end of the inner side of the ventilation pipe.
[0009] The present invention is further configured such that the adjusting mechanism includes a bidirectional screw, and each of the two sets of pressure plates is provided with a mounting block at its top. The two sets of mounting blocks are perforated with threaded holes. The outer sides of the bidirectional screw are threadedly connected to the threaded holes of one set of mounting blocks, and both ends of the bidirectional screw are rotatably connected to both ends of the second chamber. Guide components are provided on both the front and rear sides of the two sets of pressure plates, and the bottoms of the two sets of pressure plates slide tightly against the bottom of the second chamber via the guide components. The sliding adjustment of the pressure plates is achieved through the threaded engagement of the bidirectional screw and the mounting blocks, which can precisely control the moving distance of the two sets of pressure plates, thereby accurately adjusting the area of the ventilation hole blocked and achieving precise control of the ventilation volume. The rotatable connection between the two ends of the bidirectional screw and the second chamber ensures the stability of the screw rotation and avoids shaking during rotation that affects the adjustment accuracy.
[0010] The present invention is further configured such that the guiding component includes four sets of connecting blocks and four sets of guiding blocks. Two sets of sliding grooves are provided on both the front and rear sides of the top of the second chamber. The bottom of each of the four sets of guiding blocks is slidably connected to the corresponding sliding groove of the second chamber. A connecting block is provided on the top of each of the four sets of guiding blocks, and the front and rear sides of the two sets of pressure plates are connected to the other end of the connecting block. Through the sliding cooperation between the guiding blocks and the sliding grooves, a clear sliding trajectory is provided for the pressure plate, which can effectively limit the movement direction of the pressure plate and ensure that the bottom of the pressure plate is always in close contact with the bottom of the second chamber. It will not cause gaps due to deviation that block the ventilation holes. In addition, the four sets of guiding blocks are evenly distributed on the front and rear sides of the pressure plate, which can disperse the force when the pressure plate slides, ensuring that the adjustment mechanism drives the pressure plate to slide more effortlessly and stably.
[0011] The present invention is further configured such that the filter assembly includes an annular block, a filter plate is disposed on the inner side of the annular block, and an annular plate is rotatably disposed on the left side of the outer side of the annular block. Both the inner side of the annular plate and the left side of the outer side of the ventilation pipe are provided with threaded ends. The right side of the inner side of the annular plate is threadedly connected to the left side of the outer side of the ventilation pipe via the threaded end, and the right side of the outer side of the annular block and the inner side of the ventilation pipe are in close contact. This configuration effectively filters the incoming air, preventing bacteria and impurities from entering the first chamber, avoiding contamination of the fermentation environment by bacteria, ensuring the normal reproduction of beneficial bacteria, and improving the qualification rate of fermented feed. The threaded connection between the annular plate and the ventilation pipe not only stably fixes the annular block and prevents the filter plate from shaking due to airflow impact during ventilation, but also enables quick assembly and disassembly of the filter assembly.
[0012] The present invention is further configured such that a sealing gasket is provided at the bottom of both sets of pressure plates, and the bottom of both sets of sealing gaskets slides tightly against the top of the second chamber; during the sliding process, the friction between the pressure plate and the top of the second chamber can be reduced, which not only avoids wear caused by friction, but also improves the sealing effect of the pressure plate on the ventilation hole.
[0013] The present invention is further configured such that the right end of the bidirectional screw passes through the right end of the second chamber and is provided with a rotating handle; the rotating handle provides a convenient point of force application for rotating the bidirectional screw, and the screw can be easily rotated without the use of additional tools.
[0014] The present invention is further provided with anti-slip texture on the outer side of the annular plate; by increasing the friction between the hand and the annular plate, the problem of slipping when the surface of the annular plate is smooth is solved.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides a pig feed fermenter with the following advantages:
[0017] 1. By adding a second chamber, ventilation pipes, and cooling fans, active cooling of the first chamber is achieved: outside air enters the chamber after filtration, which can remove excess heat generated by fermentation and prevent the beneficial live bacteria from being inactivated due to excessive temperature. At the same time, the adjustment mechanism drives the pressure plate to slide, which can flexibly control the ventilation volume of the ventilation holes and can be adjusted according to the temperature requirements of the fermentation stage, thus improving the flexibility of temperature control.

[0027] Please see Figure 1-5 A pig feed fermenter includes a fermentation tank 1, a first chamber 2, a feed pipe 3 at the front end of the first chamber 2, a stirring mechanism 4 inside the first chamber 2, a discharge pipe 5 at the bottom of the first chamber 2, a second chamber 6 above the first chamber 2, two sets of ventilation holes 7 evenly arranged through the top of the first chamber 2 and penetrating the second chamber 6, an adjustment mechanism at the bottom of the second chamber 6, pressure plates 8 slidably connected to both sides of the bottom of the second chamber 6 via the adjustment mechanism, and the bottoms of the two sets of pressure plates 8 are both above the ventilation holes 7 of the second chamber 6, a reserved hole at the left end of the second chamber 6, a ventilation pipe 9 inside the reserved hole, a cooling fan 10 inside the right end of the ventilation pipe 9, and a filter assembly inside the left end of the ventilation pipe 9.
[0028] In this embodiment, during use, pig feed raw materials are first fed into the first chamber 2 through the feed pipe 3 at the front end of the first chamber 2. The stirring mechanism 4 in the first chamber 2 is then activated to stir and mix the raw materials in preparation for fermentation. During the fermentation process, if the first chamber 2 needs to be cooled down due to microbial metabolism or excessively high ambient temperature, the operator slides the two sets of pressure plates 8 through the adjustment mechanism, so that the two sets of pressure plates 8 are moved away from the ventilation hole 7 by the guide component. Then, the cooling fan 10 on the right side of the ventilation pipe 9 is activated. When the cooling fan 10 rotates, outside air enters through the left end of the ventilation pipe 9, is filtered by the filter component, enters the second chamber 6, and then enters the first chamber 2 through the ventilation hole 7 at the top of the first chamber 2, thus achieving air circulation and heat dissipation.
[0029] More specifically, the operator rotates the bidirectional screw 11 by rotating the handle 20, which drives the two sets of mounting blocks 12 to move relative to or towards each other along the screw axis, thereby causing the two sets of pressure plates 8 to slide at the bottom of the second chamber 6. The guide components on the front and rear sides of the two sets of pressure plates 8 will assist the pressure plates 8 in sliding, ensuring that the pressure plates 8 are always in close contact with the bottom of the second chamber 6 to avoid displacement, until the ventilation hole 7 is closed or opened.
[0030] Please see Figure 1 and Figure 4 As one embodiment of the filter assembly: the filter assembly includes an annular block 17, a filter plate 18 is provided on the inner side of the annular block 17, an annular plate 16 is rotatably provided on the outer left end of the annular block 17, the inner side of the annular plate 16 and the outer left end of the ventilation pipe 9 are both provided with threaded ends, the inner right end of the annular plate 16 is threadedly connected to the outer left end of the ventilation pipe 9 through the threaded end, and the outer right end of the annular block 17 and the inner side of the ventilation pipe 9 are in close contact.
[0031] Specifically, during ventilation, outside air enters from the left end of the ventilation duct 9, first passing through the filter plate 18 inside the annular block 17. The filter plate 18 filters out bacteria, dust, and other impurities from the air. The filtered air then enters the second chamber 6, and finally enters the first chamber 2 through the ventilation hole 7. When it is necessary to clean or replace the filter plate 18, the annular plate 16 is rotated in the opposite direction to separate it from the threaded end of the ventilation duct 9, allowing the annular block 17 and filter plate 18 to be removed. After the operation is completed, the annular plate 16 is used to re-fix the filter plate 18.
[0032] Please refer to Figures 2-4 As a further embodiment of the guide assembly: the guide assembly includes four sets of connecting blocks 14 and four sets of guide blocks 15. Two sets of sliding grooves are provided on the front and rear sides of the top of the second chamber 6. The bottom of the four sets of guide blocks 15 are slidably connected to the corresponding sliding groove of the second chamber 6. The top of the four sets of guide blocks 15 is provided with connecting blocks 14, and the front and rear sides of the two sets of pressure plates 8 are connected to the other end of the connecting blocks 14.
[0033] Specifically, when the bidirectional screw 11 rotates, the two sets of mounting blocks 12 drive the pressure plate 8 to slide, and the connecting blocks 14 on the front and rear sides of the pressure plate 8 will synchronously drive the guide block 15 to move, thus guiding the mounting block 12.
[0034] In summary, the overall equipment is in use (or running):
[0035] In use, pig feed raw materials are first fed into the first chamber 2 through the feed pipe 3 at the front end of the first chamber 2. The stirring mechanism 4 in the first chamber 2 is started to stir and mix the raw materials to prepare for fermentation. During the fermentation process, if the first chamber 2 needs to be cooled down due to microbial metabolism or excessively high ambient temperature, the operator rotates the double-ended screw 11 by rotating the handle 20, which drives the two sets of mounting blocks 12 to move relative to or towards each other along the screw axis. This causes the two sets of pressure plates 8 to slide at the bottom of the second chamber 6. The connecting blocks 14 on the front and rear sides of the two sets of pressure plates 8 drive the guide blocks 15 to assist the pressure plates 8 in sliding, ensuring that the pressure plates 8 are always in close contact with the bottom of the second chamber 6 to avoid displacement. This causes the two sets of pressure plates 8 to move the sealing gasket 19 away from the ventilation hole 7. Then, the cooling fan 10 on the right side of the ventilation pipe 9 is started. When the cooling fan 10 rotates, outside air enters through the left end of the ventilation pipe 9, is filtered by the filter assembly, enters the second chamber 6, and then enters the first chamber 2 through the ventilation hole 7 at the top of the first chamber 2, achieving air circulation and heat dissipation.
[0036] When the filter plate 18 needs to be cleaned or replaced, the operator can rotate the annular plate 16 through the anti-slip texture 13 to separate it from the threaded end of the ventilation pipe 9, and then remove the annular block 17 and the filter plate 18. After the operation is completed, the annular plate 16 can be used to fix it back in place.
[0037] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
