Description

Technical Field

[0001] This utility model belongs to the technical field of biological feed production, and specifically relates to a biological feed fermentation device. Background Art

[0002] Biological feed production is to mix the prepared plant materials, animal feed by-products and fermenting agents together, add purified water or fermenting agents to adjust the water content, mix evenly and then put them into a fermentation tank, compact and seal.

[0003] The raw materials in the fermentation tank are placed in a well-ventilated and temperature-appropriate place for fermentation. The fermentation time depends on the specific situation, generally about 2 - 7 days. When a strong fragrance appears during the fermentation process, it can be judged that the fermentation is completed.

[0004] The raw materials in the fermentation tank are gathered in a larger chamber for unified fermentation. If the purity of any raw material is insufficient or the cleanliness of any corner of the fermentation tank is insufficient, it is possible for miscellaneous bacteria to mix in. The raw materials are all mixed together, and the isolation degree against miscellaneous bacteria is not high. Once the miscellaneous bacteria grow, the loss is relatively large. For this reason, we propose a biological feed fermentation device. Content of the Utility Model

[0005] The purpose of this utility model is to provide a biological feed fermentation device, which divides the raw materials into several portions and seals them separately in the fermentation barrel. The raw materials are isolated from each other, which can reduce the loss caused by the growth and spread of miscellaneous bacteria.

[0006] The technical solution adopted by this utility model is specifically as follows:

[0007] A biological feed fermentation device includes a fermentation barrel. A number of alloy cylinders are inserted side by side inside the fermentation barrel. A sealing cover is arranged outside the fermentation barrel. A number of rubber plugs are adhesively bonded at intervals on the lower surface of the sealing cover. One end of each rubber plug is inserted into the opening of the fermentation barrel and is in interference fit with the opening of the adjacent alloy cylinder. Four handle bolts are installed through the four corners of the sealing cover in a threaded manner. The screw rods of the four handle bolts are respectively threadedly connected with the four corners of the opening of the fermentation barrel. During operation, each raw material is mixed in a feed mixer at a specified ratio, and purified water is added to adjust the water content to about 40%. Then they are put into each alloy cylinder respectively, filled and compacted. The alloy cylinders are arranged side by side with the openings facing upwards and stacked into the fermentation barrel until the fermentation barrel is full. Then the opening of the fermentation barrel is covered with the sealing cover, and each handle bolt is rotated clockwise and screwed into the four corners of the opening of the fermentation barrel respectively to tighten the sealing cover, driving the rubber plugs to plug the openings of the corresponding alloy cylinders for sealing. The raw materials are divided into several portions and sealed separately in the fermentation barrel, and then placed together in a well-ventilated and temperature-appropriate place for fermentation, generally about 2 - 7 days. Even if miscellaneous bacteria grow in one portion, it is isolated from other portions of raw materials, which can reduce the loss caused by the growth and spread of miscellaneous bacteria.

[0008] Elastic columns are adhesively bonded to the bottom surfaces of the alloy cylinders. When the alloy cylinders are in place, the alloy cylinders and the fermentation barrel squeeze the elastic columns, and the deformation of the elastic columns is used for buffering to avoid hard collisions.

[0009] A number of limiting grooves are spaced apart on the lower wall of the fermentation barrel. The limiting grooves are all facing the elastic columns of adjacent alloy cylinders. The elastic columns fall into the limiting grooves to straighten the alloy cylinders along the axial direction of the fermentation barrel, playing a guiding role.

[0010] Two coaxial rotating shafts are respectively fixed on both sides of the fermentation barrel. A braking motor is fixed at one end of one of the rotating shafts away from the fermentation barrel. By controlling the start of the braking motor, the two rotating shafts and the fermentation barrel are rotated unidirectionally, driving each alloy cylinder to rotate, so that the water shakes and diffuses circumferentially inside the alloy cylinder, so as to act on all the raw materials in the alloy cylinder.

[0011] Bearing seats are rotatably installed on the outer sides of the two rotating shafts. One of the bearing seats is fixedly connected to the braking motor, and the two bearing seats are grounded to stably support the two rotating shafts and the fermentation barrel.

[0012] Silicone bands are fixed on the outer edges of the alloy cylinders. The silicone bands are all annular, isolating between the alloy cylinders, keeping a certain distance between the alloy cylinders, and facilitating the insertion of clips to take them out by clamping.

[0013] The technical effects obtained by this utility model are as follows:

[0014] In a biological feed fermentation device of this utility model, during operation, each raw material is mixed in a specified proportion in a feed mixer, and clean water is added to adjust the water content to about 40%. Then, it is filled into each alloy cylinder, filled and compacted. The alloy cylinders are sequentially arranged side by side with the openings facing upwards in the fermentation barrel until the fermentation barrel is full. Then, the opening of the fermentation barrel is covered with a sealing cover, and each handle bolt is rotated along the thread and screwed into the four corners of the opening of the fermentation barrel to tighten the sealing cover, driving the rubber plug to be inserted into the opening of the corresponding alloy cylinder for sealing. The raw materials are divided into several portions and separately packaged in the fermentation barrel, and then placed together in a well-ventilated and appropriately temperature-controlled place for fermentation. Generally, it takes about 2 to 7 days for fermentation. Even if bacteria grow in one portion, it is isolated from other portions of raw materials, which can reduce the losses caused by the growth and spread of bacteria. Description of the Drawings

It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0023] As Figures 1-5 shown, a biological feed fermentation device includes a fermentation barrel 1, several alloy cylinders 2 are inserted side by side inside the fermentation barrel 1, a sealing cover 4 is arranged outside the fermentation barrel 1, several rubber stoppers 3 are adhesively bonded at intervals on the lower surface of the sealing cover 4, one end of each rubber stopper 3 is inserted into the opening of the fermentation barrel 1 and is in interference fit with the opening of the adjacent alloy cylinder 2, handle bolts 5 are threadedly installed through the four corners of the sealing cover 4, and the screw rods of the four handle bolts 5 are respectively threadedly connected to the four corners of the opening of the fermentation barrel 1. Before use, the fermentation barrel 1, alloy cylinder 2, rubber stopper 3, sealing cover 4 and handle bolt 5 all need to be subjected to high-temperature sterilization treatment. During operation, each raw material is mixed in a feed mixer at a specified ratio, and clean water is added to adjust the water content to about 40%. Then, it is put into each alloy cylinder 2 respectively, filled and compacted. The alloy cylinders 2 are arranged side by side with the openings facing up in the fermentation barrel 1 until the fermentation barrel 1 is full. Then, the sealing cover 4 is used to cover the opening of the fermentation barrel 1, and each handle bolt 5 is rotated forward and screwed into the four corners of the opening of the fermentation barrel 1 along the thread to tighten the sealing cover 4, driving the rubber stopper 3 to plug the opening of the corresponding alloy cylinder 2 for sealing, dividing the raw materials in the fermentation barrel 1 into several portions and sealing them separately, and then placing them together in a well-ventilated and temperature-appropriate place for fermentation. Generally, it takes about 2 to 7 days for fermentation. Even if bacteria grow in one portion, it is isolated from other portions of raw materials, which can reduce the losses caused by the growth and spread of bacteria.

[0024] As Figure 1 、 Figure 4 and Figure 5 shown, the distance between each alloy cylinder 2 does not exceed 1 cm, the idle space is small, and the rubber stopper 3 can be made of food-grade silica gel material, which has no toxic or side effects on the feed. After sealing, there is no air circulation inside the alloy cylinder 2, and the heat preservation performance is good.

[0025] As Figure 2 and Figure 4 shown, elastic columns 6 are bonded to the bottom surfaces of the alloy cylinders 2. When the alloy cylinders 2 are in place, the alloy cylinders 2 squeeze the elastic columns 6 against the fermentation barrel 1, and the deformation of the elastic columns 6 is used for buffering to avoid hard collisions.

[0026] As Figure 3 and Figure 4 shown, a number of limiting grooves 7 are spaced apart on the lower wall of the fermentation barrel 1, and the limiting grooves 7 are all directly opposite the elastic columns 6 of the adjacent alloy cylinders 2. The elastic columns 6 fall into the limiting grooves 7 to straighten the alloy cylinders 2 along the axial direction of the fermentation barrel 1, playing a guiding role.

[0027] As Figure 1 , Figure 2 and Figure 3 shown, two coaxial rotating shafts 8 are respectively fixed on both sides of the fermentation barrel 1. One end of one rotating shaft 8 far from the fermentation barrel 1 is fixed with a brake motor 9. The brake motor 9 can select the YEJ series electromagnetic brake motor, and its signal is connected to the industrial computer of the processing station to control the start of the brake motor 9, rotate the two rotating shafts 8 and the fermentation barrel 1 unidirectionally, drive each alloy cylinder 2 to rotate, and make the water shake and diffuse circumferentially inside the alloy cylinder 2 so as to act on all the raw materials in the alloy cylinder 2.

[0028] As Figure 1 , Figure 2 and Figure 3 shown, bearing seats 10 are rotatably installed on the outer sides of the two rotating shafts 8. One of the bearing seats 10 is fixedly connected to the brake motor 9, and the two bearing seats 10 are grounded to stably support the two rotating shafts 8 and the fermentation barrel 1.

[0029] As Figure 2 and Figure 4 shown, silica gel bands 11 are fixed on the outer edges of the alloy cylinders 2. The silica gel bands 11 are all annular, isolating between the alloy cylinders 2 to keep a certain distance between the alloy cylinders 2, which is convenient for inserting a clip to take out by clamping.

[0030] The working principle of this utility model is as follows: During operation, various raw materials are mixed in a feed mixer at a specified ratio, and clean water is added to adjust the water content to about 40%. Then, they are respectively filled into each alloy cylinder 2, filled and compacted. The alloy cylinders 2 are arranged side by side with their openings facing upwards in the fermentation barrel 1 until the fermentation barrel 1 is full. Then, the opening of the fermentation barrel 1 is covered with a sealing cover 4, and each handle bolt 5 is rotated and screwed into the four corners of the opening of the fermentation barrel 1 along the thread to tighten the sealing cover 4, driving the rubber plug 3 to be inserted into the corresponding opening of the alloy cylinder 2 for sealing. The raw materials are divided into several portions and respectively packaged in the fermentation barrel 1, and then placed together in a well-ventilated and temperature-appropriate place for fermentation. Generally, it takes about 2 to 7 days for fermentation. Even if bacteria grow in one portion, it is isolated from the other portions of raw materials, which can reduce the losses caused by the growth and spread of bacteria.

[0031] The above description is only the preferred embodiment of this utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model.
