Description

Technical Field

[0001] This utility model relates to the field of fermentation bed technology, specifically to a fermentation bed device for environmentally friendly beef cattle breeding. Background Technology

[0002] Fermentation bed is a general term for the bedding material filled into the bedding tank, and it is one of the core technologies in the deep-sea microbial fermentation bed breeding method. Good bedding material should be inexpensive and readily available, make animals comfortable and happy, absorb little water and dust, contain few toxic and harmful substances, and prevent feces and urine from easily decomposing.

[0003] A search revealed a utility model patent with authorization announcement number CN215123054U, which discloses an environmentally friendly fermentation bed device for beef cattle farming, relating to the field of animal husbandry. The device includes a placement chamber with four support columns at its lower end. A bedding layer is placed inside the placement chamber. The bottom plate of the placement chamber has several discharge holes for discharging the bedding. The support columns create a gap between the bottom plate and the ground. A connecting plate is detachably connected to the lower end of the bottom plate. Several blocking blocks are provided on the connecting plate, each corresponding to one of the discharge holes. The blocking blocks are positioned within the discharge holes to prevent the bedding from being discharged.

[0004] Traditional beef cattle farming often uses cement floors or ordinary bedding beds, which have problems such as manure accumulation, high ammonia concentration, and difficulty in replacing bedding. Although existing fermentation bed technology can degrade manure, it is prone to hardening after long-term use and requires manual cleaning before it can be used again, resulting in a long period of inactivity in beef cattle farming.

[0005] Therefore, an environmentally friendly fermentation bed device for beef cattle farming is proposed to solve the problems mentioned above. Utility Model Content

[0027] Please see Figure 1 - Figure 6This embodiment of an environmentally friendly fermentation bed device for beef cattle includes a placement cavity 1. Two sliding seats 2 are slidably connected inside the placement cavity 1, and the two sliding seats 2 are symmetrically arranged. A rotating shaft 35 is installed inside each sliding seat 2 via a bearing, and the rotating shaft 35 passes through the sliding seat 2. A bed body 3 is fixedly connected between the two rotating shafts 35. The front and rear outer walls of the bed body 3 are slidably connected to the placement cavity 1, and the left and right outer walls of the bed body 3 are slidably connected to the two sliding seats 2 respectively. A perforated plate 31 is fixedly connected to the middle of the inner side of the bed body 3. Metal mesh 32 is fixedly connected to both the upper and lower surfaces of the perforated plate 31. A gravel layer 33 and a bedding layer 34 are sequentially laid above the upper metal mesh 32. The metal mesh 32, gravel layer 33, and bedding layer 34 are all slidably connected inside the bed body 3.

[0028] The placement cavity 1 has a fixedly connected discharge ramp 101 at its inner bottom, and the discharge ramp 101 is inclined. A discharge port 102 is located on the right side wall of the placement cavity 1, corresponding to the lower part of the discharge ramp 101. After the bed 3 is flipped, the used gravel layer 33 and the padding layer 34 can fall freely and slide along the discharge ramp 101 to the discharge port 102 and be discharged from the placement cavity 1. A support ring 8 is fixedly connected to the middle of the inner side of the placement cavity 1, and the support ring 8 abuts against the bottom of both the slide 2 and the bed 3. The support ring 8 provides auxiliary support for the slide 2 and the bed 3.

[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, support plates 4 are welded to the left and right outer walls of the placement cavity 1. A hydraulic cylinder 5 is fixedly installed at the upper end of each support plate 4. A connecting plate 6 is fixedly connected to the end of the telescopic shaft of the hydraulic cylinder 5. A connecting column 7 is fixedly connected to the bottom of the connecting plate 6. The lower end of the connecting column 7 is fixedly connected to the top of the slide block 2.

[0030] like Figure 5 and Figure 6 As shown, a driven gear 9 is fixedly connected to the end of the left rotating shaft 35. A motor 10 is fixedly mounted on the left slide 2, and the motor 10 is located below the driven gear 9. A drive gear 11 is fixedly connected to the end of the output shaft of the motor 10, and the drive gear 11 and the driven gear 9 form a meshing transmission connection. The motor 10 drives the drive gear 11 to rotate, and the drive gear 11 drives the bed 3 to rotate through the transmission between the driven gears 9, and reverses direction up and down.

[0031] Furthermore, a connecting rod 12 is connected to the top inner side of the slide 2. A sleeve 13 is fixedly connected to the end of the connecting rod 12, and the sleeve 13 is slidably connected to the outside of the circumferential surface of the rotating shaft 35.

By setting the ball bearing 16, the relative friction between the sleeve 13 and the rotating shaft 35 can be reduced.

[0032] The specific implementation process of this utility model is as follows: In use, firstly, a gravel layer 33 and a bedding layer 34 are laid in sequence inside the bed 3, and then it can be used normally. The double-layer metal mesh 32 and the gravel layer 33 support the bedding layer 34, which can improve the air permeability of the bed 3, promote the aerobic fermentation of microorganisms in the bedding layer 34, effectively decompose cattle manure and urine, and reduce ammonia emissions. If the bedding layer 34 needs to be replaced later, simply drive the slide 2 upward through the hydraulic cylinder 5, so that the bed 3 leaves the placement cavity 1. Then, with the help of the motor 10, drive the bed 3 to rotate 180°, so that the used gravel layer 33 and bedding layer 34 will automatically fall off under the action of gravity and be discharged from the discharge port 102 through the discharge ramp 101. Then, the new gravel layer 33 and bedding layer 34 are filled. The loading and unloading do not affect each other. The whole system realizes the rapid cleaning of livestock waste and improves the efficiency of breeding. It is especially suitable for the environmental management needs of large-scale beef cattle farms.
