Description

Technical Field

[0001] The present invention relates to the technical field of livestock breeding, and particularly relates to a fermentation bed for pig breeding and a pig house having the fermentation bed. Background Art

[0002] The fermentation bed breeding technology is to build a fermentation bed in a pigsty using some highly beneficial microorganisms and bedding materials. Pigs directly excrete their excreta on the fermentation bed. By using the pigs' habit of digging and turning, and with the assistance of manual raking, the pig manure, urine and bedding materials are fully mixed. Through the decomposition and fermentation of beneficial fermentation microorganism colonies, the organic substances in the pig manure and urine are fully decomposed and transformed.

[0003] As a technology that has been mature for many years, fermentation bed breeding has the advantages of less environmental pollution, excellent growth conditions of live pigs, energy conservation and water conservation, etc. However, since the decomposition of excreta requires the decomposition by bacteria colonies, in order to maintain a high efficiency, the fermentation bed filler needs to be frequently turned over.

[0004] In the prior art, the methods for turning over the filler are roughly as follows: 1. Turning over by pigs, 2. Manual turning over, 3. Mechanical turning over. The above method 1 has problems of uncontrollability and unevenness. Method 2 has problems of high labor cost, time-consuming and laborious. Method 3 has problems of large equipment investment and high energy consumption.

[0005] Therefore, there is a need to provide a fermentation bed that can induce pigs to autonomously and evenly turn over the filler. Summary of the Invention

[0006] To solve the problems existing in the above technologies, the present invention provides a fermentation bed for pig breeding, including a feeding trough. The feeding trough is filled with a fermentation bed filler. A plurality of sunken placement grooves are provided on the ground of the feeding trough, and a liquid outlet valve is arranged in the placement groove. The liquid outlet valve can release a liquid attractant.

[0007] Among them, the liquid outlet valve includes

[0008] A fixed pipe, the upper part of the fixed pipe is an upper fitting part;

[0009] A movable pipe, the movable pipe has a closed top wall, a through hole is provided on the top wall. The lower part of the movable pipe is a lower fitting part. The upper fitting part and the lower fitting part can be mutually fitted, and the movable pipe can move axially relative to the fixed pipe;

[0010] An elastic member, the fixed pipe and the movable pipe are connected by the elastic member;

[0011] A vertical rod, the vertical rod is located inside the liquid outlet valve, the vertical rod is fixedly connected to the inner wall of the fixed pipe, and the vertical rod is adapted to the through hole.

[0012] Wherein, a sealing ring is arranged between the upper fitting part and the lower fitting part.

[0013] Wherein, a guiding pipe is arranged at the bottom side of the top wall of the movable pipe. The guiding pipe is coaxial with the through hole. The guiding pipe is sleeved outside the vertical rod. A gap is arranged on the side wall of the guiding pipe. When the movable pipe moves to a position far away from the fixed pipe, the gap communicates with the through hole.

[0014] Wherein, the outer edge of the top wall and the outer edge of the top surface of the placing groove are sealingly connected through a flexible sealing member.

[0015] Wherein, an electromagnetic valve is arranged at the bottom end of the liquid outlet valve.

[0028] The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] As Figure 1 shown, a fermentation bed for pig breeding provided by an embodiment includes a feeding trough 7. The feeding trough 7 is filled with fermentation bed filler. The filler is a prior art, which includes wood chips and straw debris as the main filler body, and is accompanied by composite bacteria to treat excreta in the process of pig breeding.

[0030] A plurality of sunken placement grooves 4 are arranged on the ground of the feeding trough 7. A liquid outlet valve is arranged in the placement groove 4. The liquid outlet valve can release a liquid attractant. The liquid attractant can be a common attractant on the market or a sucrose solution. The preferred sucrose solution ratio is sucrose: water = 3 - 5 g / ml;

[0031] The setting density of the placement grooves 4 is at least one per square meter.

[0032] The above liquid outlet valve is connected to a pipeline network 5 buried under the ground of the feeding trough 7. An electromagnetic valve 6 can be arranged between the pipeline network 5 and the liquid outlet valve to control the liquid output. A plurality of electromagnetic valves 6 are controlled by a central controller (prior art). The pipeline network 5 is externally connected to an attractant tank.

[0033] When in use, the central controller opens the electromagnetic valve 6 on time, and it is preferred that each liquid outlet valve outputs 10 - 30 ml of sucrose solution. For a fermentation bed filler with a thickness of 40 - 60 cm, the liquid output of the liquid outlet valve is at least 10 ml, which can enable pigs to quickly discover the attractant. After smelling the attractant, the pigs turn over the filler of the fermentation bed to activate the microbial community and improve the vitality of the fermentation bed.

[0034] Among them, specifically, it can be taken that the attractant is released 3 hours after the pigs are fed every day, and the multiple liquid outlet valves are controlled to release the attractant in sequence, Figure 4 for example, six liquid outlet valves are released in sequence, and the release interval between each row is 30 minutes.

[0035] Or all the liquid outlet valves release the attractant simultaneously 3 hours after the pigs are fed every day.

[0036] During the use process, since there are a large amount of debris and dirt inside the filler, and the liquid outlet valve is arranged on the ground of the feeding trough 7 and the opening faces, the liquid outlet valve is prone to blockage. Therefore, the liquid outlet valve can be designed as follows, as Figures 2 - 4 shown:

[0037] The liquid outlet valve includes:

[0038] A fixed tube 1, the upper part of the fixed tube 1 is an upper fitting part 11;

[0039] A movable tube 2, the movable tube 2 has a closed top wall 24, a through hole 22 is provided on the top wall 2, the lower part of the movable 2 is a lower fitting part 25, the upper fitting part 11 and the lower fitting 25 part can be sleeved with each other, that is, the outer diameter of one fitting part is approximately equal to the inner diameter of the other fitting part, a sealing ring 23 is provided between the two fitting parts, and the movable tube 2 can move axially relative to the fixed tube 1;

[0040] An elastic member 13, which is a spring, the fixed tube 1 and the movable tube 2 are connected by the elastic member 13;

[0041] A vertical rod 12, the vertical rod 12 is located inside the liquid outlet valve, the vertical rod 12 is fixedly connected to the inner wall of the fixed tube 1, and the vertical rod 12 is adapted to the through hole 22.

[0042] When in use, the pressure is released from the pipe network 5 to the inside of the liquid outlet valve. After the pressure reaches a certain value, the movable tube 2 is pushed up, the top of the vertical rod 12 is separated from the through hole 22 so that the attractant is released from the through hole 22. After the release is completed, the pressure drops, and the movable tube 2 returns to its original position due to the pulling force of the elastic member 13. The vertical rod 12 penetrates into the through hole 22 again to seal it. When outputting the inducer, the vertical rod 12 and the through hole 22 can be cleaned. When returning to its original position, the vertical rod 12 penetrating into the through hole can also push out the blocking substances in the through hole to complete automatic cleaning and prevent blockage.

[0043] In order to prevent the vertical rod 12 from shifting, as Figure 3 and Figure 4 shown, a guide tube 21 can be provided on the bottom side of the top wall 24 of the movable tube 2. The guide tube 21 is coaxial with the through hole 22. The guide tube 21 is sleeved outside the vertical rod 12. An axial gap 211 is provided on the side wall of the guide tube 21. When the movable tube 2 moves to a position away from the fixed tube 1, the gap 211 leaks out and communicates with the through hole 22.

[0044] Other embodiments

[0045] Since the upper fitting part 11 and the lower fitting part 25 will be partially separated when the inducer is released, in order to prevent the packing debris from falling into the gap between them and to protect the components inside the placement groove 4 from being eroded, a flexible seal 3 can be used to seal the connection between the outer edge of the top wall 24 and the outer edge of the top surface of the placement groove 4. It can be selected as a thin annular anti-corrosion rubber ring.

[0046] On the premise of setting the flexible seal 3, as Figure 5As shown, the elastic member 13 can be placed outside the liquid outlet valve, so as to avoid the long-term contact between the elastic member 13 and the liquid inducer, prevent their mutual influence, and make it more convenient for the maintenance and replacement of the elastic member 13.

[0047] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.
