Description

Technical Field

[0001] The present invention relates to the technical field of feed mixing devices, and specifically relates to a mixing device for processing Leymus chinensis single-cell protein feed. Background Art

[0002] Leymus chinensis single-cell protein feed is a feed designed according to the nutritional needs of sheep. It combines the nutritional value of Leymus chinensis with the high-protein and high-nutrition characteristics of single-cell protein; the microbial cells obtained through fermentation engineering; the mixing ratio should be adjusted according to factors such as the age, sex, weight, and production stage of the sheep. When mixing the feed, generally, the forage and auxiliary materials are mixed together. The device for mixing the feed usually uses a stirrer to stir the feed, and the stirred feed is granulated by a granulator.

[0003] Currently, when mixing Leymus chinensis single-cell protein feed, usually the forage is added into the interior of the stirrer, and then a certain amount of auxiliary materials such as soybean meal and peanut cake are added according to the ratio. When adding the forage into the interior of the stirrer, a spiral auger or manual feeding is used. No matter which feeding method is adopted, a large amount of feed powder dust will be generated during feeding and the initial stage of stirring. Currently, a blower is used to handle the dust during feeding, and a filter screen is provided inside the exhaust duct for collection. After collection, water spraying is used to wash the collected feed, and the washed water flows back into the interior of the stirrer again. However, the method of cleaning with water not only easily causes the feed to adhere to the filter screen, but also the water after cleaning flows back into the interior of the stirrer, affecting the proportion of water in the feed stirring and the dry humidity; when adding auxiliary materials, generally an air pump feeding method is used, and various auxiliary materials are added into the interior of the stirrer in sequence. When adding various auxiliary materials, pre-mixing is not carried out. Adding separately not only wastes time, but also the forage easily causes the wrapping of the auxiliary materials, resulting in uneven mixing between the two auxiliary materials; no dust-proof component is provided outside the stirrer, and feed powder will float out from the outside of the stirrer during the initial stage of stirring and feeding, affecting the environment of the processing site.

[0023] Specifically, refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown, the premixing mechanism 3 includes a fixing plate 301.

A support plate 305 is fixedly connected to the mixing barrel 302. A mixing shaft 306 is rotatably connected to the support plate 305. A plurality of mixing rods 307 are fixedly connected to the mixing shaft 306 in an annular array. A feeding pipe 303 extending to the top of the stirrer 1 is fixedly connected to the bottom of the mixing barrel 302. A valve 304 is installed on the feeding pipe 303; There are two mixing shafts 306 axially opposite to each other with respect to the mixing barrel 302, and the mixing rods 307 on the two mixing shafts 306 are arranged in a staggered manner; A rotating seat 701 is fixedly connected to the support plate 305. A rotating cylinder 702 is rotatably connected to the rotating seat 701. The rotating cylinder 702 is fixedly connected to the rotating shaft 204 at the output end of the first motor 206. Two bevel gears one 703 are fixedly connected to the two opposite ends of the rotating cylinder 702. The tops of the two mixing shafts 306 are fixedly connected with bevel gears two 704. The two bevel gears one 703 are respectively meshed with the two bevel gears two 704. The diameter of the bevel gear one 703 is larger than that of the bevel gear two 704; While the first motor 206 drives the rotation of the rotating shaft 204, it also drives the rotation of the rotating cylinder 702 on the rotating seat 701. As the rotating cylinder 702 rotates, the two bevel gears one 703 are also driven. Further, the two bevel gears one 703 drive the rotation of the bevel gears two 704 on the two mixing shafts 306, thus realizing the simultaneous rotation of the two groups of mixing rods 307, and the rotation directions are opposite. Different auxiliary materials are added into the interior of the mixing barrel 302 through an air pump, realizing the mixing of different auxiliary materials. After the mixing is completed, the valve 304 is opened, and then the well-mixed auxiliary materials will fall from the feeding pipe 303 into the interior of the stirrer 1, realizing the premixing of the auxiliary materials and avoiding being wrapped by forage and uneven mixing caused by adding them into the stirrer 1 in batches.

[0024] Specifically, referring to Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 and Figure 10As shown, the spraying mechanism 4 includes a spray pipe 404. A plurality of spray pipes 404 are fixedly arranged at equal intervals along the edge of the stirrer 1. A plurality of nozzles 409 are axially installed on the side wall of the spray pipe 404. An L-shaped connecting pipe 402 is welded to the bottom of each of the plurality of spray pipes 404, and the ends of the plurality of connecting pipes 402 are connected to a ring-shaped water inlet pipe 401. The spraying mechanism 4 further includes a protective shell 403. The outer walls of the plurality of spray pipes 404 are rotatably connected to the protective shell 403. A communication port 408 corresponding to the nozzle 409 is axially arranged on the side wall of the protective shell 403. A limiting ring 405 located at the top of the protective shell 403 is fixedly connected to the spray pipe 404. The spraying mechanism 4 further includes a gear 406. A gear 406 having an I-shaped cross-section is fixedly connected to the side wall of each of the plurality of protective shells 403, and an internal gear ring 407 is engaged with the inner sides of the plurality of gears 406. When there is a large amount of dust during feeding or at the initial stage of stirring, the water inlet pipe 401 is connected to a water source. Water passes through the interiors of the plurality of connecting pipes 402 from the water inlet pipe 401 and finally sprays out from the nozzles 409 on the inner wall of the spray pipe 404. Multiple groups of nozzles are aligned with the top of the stirrer 1. On the one hand, it can inhibit the dust generated during feeding or stirring, and on the other hand, it can provide moisture for the feed mixing. If the specified amount of moisture is added, the water source can be turned off. During stirring, the internal gear ring 407 of the plurality of gears 406 can be rotated to misalign the communication port 408 on the protective shell 403 with the nozzle 409, avoiding the feed splashing and blocking the nozzle 409 during stirring. When dust reduction is required again, the gear ring 407 can be rotated reversely to drive the gear 406 to rotate, and finally the communication port 408 is opened to expose the nozzle 409, and spraying can be carried out.

[0025] When the present invention is in use, first, when mixing for processing the single-cell protein feed of Leymus chinensis, forage can be added into the stirrer 1 by means of a spiral auger or manually. The second motor 601 is started to rotate the connecting column 602. Further, two turning pieces 605 can turn the forage or the forage and auxiliary materials at the axial middle position of the stirrer 1. The scraper 607 can scrape the inner wall of the stirrer 1 to increase the uniformity of stirring. Two stirring blades 604 can stir and mix the forage and auxiliary materials at the inner bottom of the stirrer 1. When adding materials and mixing, the first motor 206 and the axial flow fan 214 are started, and the dust at the initial stage of adding materials and stirring will be sucked away by the axial flow fan 214. The air passes through the inside of the housing 202 and the connecting housing 203, and the feed powder in the air is filtered by the filter screen 205. As the first motor 206 rotates counterclockwise to drive the four rotating shafts 204 to rotate counterclockwise, the filter screen 205 also rotates counterclockwise. When the filter screen 205 rotates, the feed powder on its surface will contact and scrape the inner bottom of the connecting housing 203, and the feed powder falls from the blanking port 213 and further falls into the inside of the connecting hopper 207. The clean air is discharged from the end of the connecting housing 203, realizing the timely cleaning of the feed dust on the filter screen 205. On the one hand, it avoids the blockage of the connecting housing 203 and affects the exhaust, and on the other hand, it collects the feed to avoid waste. When the dust on the stirrer 1 is not large, the electric push rod 211 can be started to drive the baffle 212 to move, and the collected feed is discharged from the connecting hopper 207, flows through the receiving hopper 210 and into the inside of the blanking hopper 209, and finally falls into the stirrer 1 for stirring; Then, while the first motor 206 drives the rotating shaft 204 to rotate, it also drives the rotating cylinder 702 on the rotating seat 701 to rotate. As the rotating cylinder 702 rotates, two first bevel gears 703 are also driven. Further, the two first bevel gears 703 drive the second bevel gears 704 on the two stirring shafts 306 to rotate, thus realizing the simultaneous rotation of the two groups of stirring rods 307, and the rotation directions are opposite. Different auxiliary materials are added into the inside of the stirring barrel 302 through an air pump, realizing the stirring of different auxiliary materials. After stirring is completed, the valve 304 is opened, and then the well-stirred auxiliary materials will fall from the blanking pipe 303 into the inside of the stirrer 1, realizing the premixing of the auxiliary materials and avoiding being wrapped by the forage and uneven mixing caused by adding them into the stirrer 1 in batches; Finally, when there is a large amount of dust during feeding or at the initial stage of stirring, connect the water inlet pipe 401 to the water source. Water passes through the interior of multiple connecting pipes 402 from the water inlet pipe 401 and finally sprays out from the nozzles 409 on the inner wall of the spray pipe 404. Multiple groups of nozzles are aligned with the top of the stirrer 1. On the one hand, it can inhibit the dust during feeding or stirring, and on the other hand, it can provide moisture for the feed mixing. If the specified amount of water is added, the water source can be closed. During stirring, the toothed ring 407 inside multiple gears 406 can be rotated to make the communication port 408 on the protective shell 403 misaligned with the nozzle 409, avoiding the feed from splashing and blocking the nozzle 409 during stirring. When dust reduction is required again, the toothed ring 407 can be rotated reversely to drive the gear 406 to rotate. Finally, the communication port 408 is opened to expose the nozzle 409, and then spraying can be carried out.
