Description

Technical Field

[0001] The invention relates to the technical field of feed processing, and in particular to a concentrated feed production device for pregnant sows. Background Art

[0002] The feeding and management of pregnant sows is an important link in the entire pig production. It determines the production performance of sows in the pig farm and affects the economic benefits of the entire pig farm.

[0003] Feeding pregnant sows with feed products with high nutritional value can ensure the production performance of pregnant sows and improve the economic benefits of pig production.

[0004] Studies have found that the application of fermentation technology can effectively improve the quality and nutritional value of feed raw materials. After fermentation, the materials can degrade macromolecular proteins and other substances in the materials into small molecular proteins that are easy for intestinal digestion and absorption. It can also degrade or eliminate anti-nutritional factors in the materials and improve the palatability of the feed. The materials can produce beneficial active substances, which can improve the utilization rate and immunity of animals to feed. The fermented raw materials obtained after fermentation treatment are high-quality and high-nutritional feed raw materials. Applying them to feed products for pregnant sows can improve the production performance of pregnant sows and improve the economic benefits of pig farming.

[0005] However, when fermented raw materials are used in production, they are more likely to form lumps during storage, which reduces the uniformity and fluidity of the materials. When they are added to conventional silos for storage, the materials may form arches, which is not conducive to the smooth production of feed products.

[0006] Pregnant sow concentrate, also known as pregnant sow concentrated feed, is currently a very mainstream feed product for pregnant sows. It is easy to use in pig farms. If fermented raw materials are used to produce pregnant sow concentrate, it will have great market potential and competitive advantages.

[0042] Preferably, the cylinder 16 is an inverted cone shell, with openings at both ends, and the diameter of the upper opening of the cylinder 16 is larger than the diameter of the lower opening of the cylinder 16. Such a structure can reduce the friction between the fermentation raw materials stored in the fermentation raw material bin 7 and the outer wall of the cylinder 16, promote the spontaneous flow of the fermentation raw materials in the fermentation raw material bin 7, reduce the possibility of arching of the materials in the fermentation raw material bin 7, and prevent the materials in the fermentation raw material bin 7 from arching.

The rotating fixing device 18 can be fixed on the inner wall of the barrel 16 by providing a bracket, etc. The rocker 17 is vertically arranged in the barrel 16 through the rotating fixing device 18. The rotating fixing device 18 can be a joint bearing (such as a spherical joint bearing or a radial joint bearing, etc.), etc. The rocker 17 can make a conical surface revolution motion around the vertical center line of the barrel 16 in the barrel 16 through the rotating fixing device 18, that is: the upper and lower ends of the rocker 17 both use the position of the rotating fixing device 18 as the cone top of the cone surface, and make a conical surface revolution motion around the vertical center line of the barrel 16, and the movement trajectory of the rocker 17 forms two upper and lower inverted cone surfaces facing each other.

[0045] The rocker 17 passes through the upper and lower ends of the cylinder 16, and the upper end of the rocker 17 is rotatably connected to the action output end of the rocking mechanism. The action output end of the rocking mechanism (rocking action mechanism) outputs the rocking action force to the upper end of the rocker 17, so that the upper and lower ends of the rocker 17 can make a conical surface orbital motion around the vertical center line of the cylinder 16 with the position of the rotating fixing device 18 as the cone top of the cone surface.

[0046] The traction device 19 is arranged on the upper part of the rocker 17, and the traction device 19 is located above the upper end of the cylinder 16. The two ends of the first traction body 20 are respectively connected to the inner wall of the fermentation raw material bin 7 and the traction device 19.

[0051] At the same time, during the movement of the rocker 17, the rocker 17 extending out from the lower end of the cylinder 16 will continuously disturb and loosen the materials in the lower part of the fermentation raw material bin 7 (i.e., above and around the discharge port 32 of the fermentation raw material bin 7), thereby improving the flow of the fermentation raw materials in the fermentation raw material bin 7, destroying the basis and conditions for the arching of the materials, and preventing the arching of the materials in the fermentation raw material bin 7; further, when the fermentation raw material bin 7 is discharged, it can also promote the smooth and rapid discharge of the materials from the discharge port 32 of the fermentation raw material bin 7, thereby improving the discharge efficiency and production efficiency.

[0068] The method for producing concentrated feed for pregnant sows using the concentrated feed production device for pregnant sows of the present invention is as follows: (1) Design product formula: When fermented raw materials (fermented feed, such as fermented soybean meal, etc.) are used to produce concentrated feed for pregnant sows, the raw material formula of the concentrated feed product for pregnant sows can be formulated and designed based on target conditions such as the nutritional needs of pregnant sows and the quality target requirements of feed products, wherein the fermented raw materials are a raw material component in the raw material formula.

[0069] (2) Prepare raw materials: Prepare the required various feed raw materials according to the raw material formula of the designed concentrated feed product for pregnant sows and the production process and technical requirements of the target product.

[0070] (3) Production and processing methods: When feeding the fermentation raw materials, the control system controls the tee 2 so that the discharge channel of the tee 2 is connected with the feed port of the dispersing device 6, the dispersing device 6 is started, the first elevator 1 is started, and the fermentation raw materials are fed into the feeding port at the lower part of the first elevator 1. The fermentation raw materials are discharged from the discharge port of the first elevator 1 and enter the tee 2, and then enter the dispersing device 6. After the fermentation raw materials are processed by the dispersing device 6, the agglomerated material lumps contained in the materials are dispersed or crushed and eliminated, and the uniformly dispersed powdered materials are discharged from the dispersing device 6 and enter the fermentation raw material bin 7 for storage, so that an appropriate amount of fermentation raw materials are stored in the fermentation raw material bin 7.

[0071] When feeding various other main raw materials (such as premixes, protein raw materials (such as fish meal, etc.)), the control system controls the tee 2 so that the discharge channel of the tee 2 is connected to the feed port of the distributor 3. The distributor 3 can be adjusted to connect the discharge channel of the tee 2 to the target batching bin 4 respectively, start the first elevator 1, and feed the other main raw materials into the feeding port at the lower part of the first elevator 1. After being discharged from the discharge port of the first elevator 1, the other main raw materials enter the tee 2, and then enter the corresponding target batching bin 4 through the distributor 3 for storage. In this way, the above process is carried out in turn for various other main raw materials, so that each batching bin 4 stores an appropriate amount of the corresponding required various other main raw materials.

[0072] According to the raw material formula of the concentrated feed product for pregnant sows determined above, the weight values ​​of various raw materials in the process of weighing 9 batches of ingredients on the ingredient scale are set in the control system.

[0073] Start the second elevator 13, the second conveyor 11, the mixer 10, and the batching scale 9. The control system automatically controls the first conveyor 5 at the bottom of each batching bin 4 and the fermentation raw material bin 7 to run in sequence. The various materials stored in the batching bin 4 and the fermentation raw material bin 7 are successively added to the batching scale 9 by the corresponding first conveyor 5. Because the first conveyor 5 set at the discharge port of each batching bin 4 and the first conveyor 5 set at the discharge port of the fermentation raw material bin 7 are all interlocked with the batching scale 9, when the weight of the raw materials added to the batching scale 9 reaches the weight of the raw materials set in the control system, the control system controls the corresponding first conveyor 5 to stop running immediately, that is, immediately stop adding the corresponding raw materials, and so on. Continue in sequence until the batching weighing program for various raw materials is completed, that is, the weight values ​​of various raw materials weighed by the batching scale 9 set in the control system are all completed.

[0074] During production, according to the need of optimizing and adjusting the raw material formula, if other feed additives with smaller addition amounts need to be added to the raw material formula, during the above-mentioned ingredient weighing step, the required raw materials weighed manually can be added to the ingredient scale 9 through the small material feeding table 8 according to the addition amount and addition timing of the product raw material formula set in the control system.

[0075] After the ingredient weighing procedure of the above-mentioned ingredient scale 9 is completed, the ingredient scale 9 opens the lower discharge door, and all the materials in the ingredient scale 9 fall into the mixer 10 below. The mixer 10 mixes the materials evenly. After the material mixing is completed, the required concentrated feed product for pregnant sows is obtained.

[0076] In the above-mentioned production and processing process, in order to avoid the fermentation raw materials stored in the fermentation raw material bin 7 from arching when the ingredients are weighed on the ingredient scale 9, which makes it impossible for the fermentation raw materials to be smoothly added to the ingredient scale 9 and affects the smooth progress of the production and processing, the anti-arching device provided in the fermentation raw material bin 7 can be turned on. The anti-arching device can disturb and loosen the fermentation raw materials stored in the fermentation raw material bin 7, destroy the basis and conditions for the arching of the fermentation raw materials, continuously loosen the fermentation raw materials in the fermentation raw material bin 7, and improve the flow of the fermentation raw materials. The anti-arching device in the present invention has a wide range of action on the materials in the fermentation raw material bin 7, and has various ways of disturbing and loosening the materials stored in the fermentation raw material bin 7, which can promote the flow of the fermentation raw materials at multiple levels and prevent the materials in the fermentation raw material bin 7 from arching.

[0077] Furthermore, according to the raw material formula of the concentrated feed product for pregnant sows and the production process technology requirements of the target product, in the present invention, the batching bin 4 can also adopt the same configuration of the fermentation raw material bin 7, such as arranging a dispersing device 6 above the batching bin 4, the dispersing device 6 is connected to the corresponding batching bin 4, and the material is processed by the dispersing device 6 before entering the batching bin 4, so that the material that needs to be dispersed can be processed; the batching bin 4 is also set to be a bin with an arc bottom, and the upper part of the batching bin 4 is a trumpet-shaped inverted opening, and the anti-arch device is applied to the batching bin 4, and the anti-arch device is set in the batching bin 4. By starting the anti-arch device, the material stored in each batching bin 4 is continuously disturbed and loosened, and the material in the batching bin 4 is continuously disturbed and loosened, so as to improve the flow of the material and prevent the material in the batching bin 4 from arching; the quality of the concentrated feed product for pregnant sows produced is further guaranteed, and the production efficiency is improved.

[0078] After the mixing process of the mixer 10 is completed, the control system controls the mixer 10 to open the lower discharge door, and the uniform material in the mixer 10 falls into the storage bin 12 below for temporary storage, and then is transported by the second conveyor 11. The material temporarily stored in the storage bin 12 enters the feed port of the second elevator 13. After being transported by the second elevator 13, the material falls from the discharge port of the second elevator 13 and is stored in the finished product bin 14 below.

[0079] The packaging scale 15 is turned on to automatically weigh and package the materials stored in the finished product bin 14 to obtain a standard bagged pregnant sow concentrated feed product.
