Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically to a feed premixer. Background Technology

[0002] Feed is a general term for the food of raised animals. During feed production, it is usually made up of a variety of feed ingredients and additives. When mixing feed ingredients, the feed is usually stirred directly. During the stirring process, the stirring blade can only move the feed ingredients that are on the same horizontal plane as the stirring blade. It is difficult for the feed ingredients in the upper and lower layers to mix, which causes the feed ingredients to separate during the stirring process, resulting in uneven mixing of the feed.

[0003] Utility model patent CN220159781 U discloses a feed premixer, including a first raw material barrel, a second raw material barrel, and a connecting pipe. The two ends of the second raw material barrel penetrate the first raw material barrel, and the second raw material barrel is rotatably installed inside the first raw material barrel. The second raw material barrel rotates relative to the first raw material barrel, dividing the internal space of the first raw material barrel into a first space and a second space. The connecting pipe is installed on the second raw material barrel, with one end connected to the second space and the other end extending into the first space to transport raw materials from the second space to the first space for mixing. Different feed ingredients are added to the first and second raw material barrels. Then, the second raw material barrel rotates, and the feed ingredients from the second space are transported to the first space through the connecting pipe. Through the rotation of the second raw material barrel, the connecting pipe continuously transports the feed ingredients from the second space to the first space, mixing the feed ingredients from the second space in the first space. Simultaneously, the connecting pipe can also stir the feed ingredients in the first space, making the different feed ingredients in the first space more evenly mixed. Therefore, this feed premixer mixes the feed ingredients in the second space into the feed ingredients in the first space, making the feed ingredients in the second space more widely distributed, thus making the mixing of different feed ingredients more uniform. In this patent, the feed ingredients are rotated in the first and second raw material barrels by a pusher plate. The feed ingredients can pass through the through holes. However, as the feed ingredients rotate with the pusher plate, the feed ingredients at the same height rotate on the same horizontal plane and will not mix with the feed ingredients at different heights. The additives are transported through the connecting pipe. The additives rotate under the pusher plate. For positions without connecting pipes, the additives are difficult to reach, resulting in uneven feed mixing. Utility Model Content

[0004] The main purpose of this utility model is to provide a feed premixer to solve the problem of uneven feed mixing caused by the difficulty in mixing feed ingredients at the same height with those at different heights during the existing feed production premixing process.

Under the guidance of the feeding pipe, the feed ingredients enter the mixing inner cylinder. The drive component drives the spiral lifting component to rotate, which moves the feed ingredients and mixes them again. The feed ingredients move upward and fall into the discharge chamber along the discharge port for mixing. This can achieve mixing of feed ingredients at different heights, making the feed ingredients more uniform. Attached Figure Description

A feed pipe 12 is provided between the inner mixing cylinder 7 and the collecting component 4. The inner mixing cylinder 7 is provided with a driving component 13 that is connected to the spiral lifting component 8. The driving component 13 drives the spiral lifting component 8 to rotate under the action of external force, so that the feed raw materials in the inner mixing cylinder 7 move upward through the discharge port 11 and enter the discharge trough 17.

[0025] Further, see Figure 3 The feeding component 3 includes multiple sets of feeding pipes 301, which are inclinedly arranged on the dispersing cylinder so that the end of the feeding pipe 301 faces the top of the distributing component 2.

[0029] Preferably, the connecting rod 14 is "L" shaped, with the short end of the connecting rod 14 connected to the bottom end of the material distribution arc disk 201, and the long end connected to the inner wall of the scattering cylinder.

[0030] Preferably, the outer diameter of the material distribution arc disk 201 is smaller than the inner diameter of the scattering cylinder.

[0031] Further, see Figure 3 The collecting component 4 includes a collecting hopper 401, the bottom end of which is connected to the feed pipe 12.

[0032] Preferably, the collecting hopper 401 has a funnel-shaped structure, with the large end of the collecting hopper 401 facing the material distribution arc plate 201, and the small end of the collecting hopper 401 connected to the material conveying pipe 12.

[0033] In the above setup, different feed ingredients and additives enter the dispersing cylinder from different feed pipes 301 and fall on the top of the distribution arc plate 201. The feed ingredients and additives slide down the arc surface of the distribution and enter the collecting hopper 401 through the material passage 5 to complete the initial mixing. The distribution arc plate 201 throws the feed ingredients and additives into the surrounding area to reduce the thickness of the feed ingredients and facilitate mixing. The feed ingredients after the initial mixing enter the mixing inner cylinder 7 through the feed pipe 12.

[0034] Further, see Figure 2 The spiral lifting component 8 includes a rotating shaft 801 and a spiral blade 802 arranged circumferentially along the rotating shaft 801. The outer edge of the spiral blade 802 is in clearance fit with the inner wall of the stirring inner cylinder 7.

[0035] Preferably, both the outer stirring cylinder 6 and the inner stirring cylinder 7 are hollow cylinders with one open end, and the open ends of the outer stirring cylinder 6 and the inner stirring cylinder 7 are located on the same horizontal plane. A cover plate 15 is provided on the open ends of the outer stirring cylinder 6 and the inner stirring cylinder 7.

[0036] Preferably, a support rod 16 is provided between the outer mixing cylinder 6 and the inner mixing cylinder 7.

[0043] In the above configuration, the drive motor 1301 rotates, driving the rotating shaft 801 and the spiral blade 802 to rotate. The spiral blade 802 drives the feed ingredients to move upward in the mixing drum, stirring the feed ingredients again. When the upward-moving feed ingredients move to the lower feed inlet 11, some feed ingredients fall from the feed inlet 11 into the feed chamber 9, and some feed continues to move upward and fall from the feed inlet 11 into the feed chamber 9, until the remaining feed ingredients fall from the uppermost feed inlet 11 into the feed chamber 9, thus mixing the feed ingredients again. During this mixing, feed ingredients at different heights can be mixed.

[0044] Further, see Figure 2 The bottom end of the mixing outer cylinder 6 is provided with a mixing hopper 21, which is connected to the discharge pipe 10.

[0045] Preferably, the mixing hopper 21 is funnel-shaped, with the larger end of the mixing hopper 21 facing the bottom of the stirring inner cylinder 7.

[0046] In the above configuration, the feed ingredients in the discharge chamber 9 fall into the mixing hopper 21 for mixing, and the finally mixed feed ingredients are discharged from the discharge pipe 10.

[0047] In this embodiment, different feed ingredients and additives enter the spreading cylinder 1 through the feed pipe 301. The different feed ingredients and additives are scattered around by the distribution arc plate 201, so that the different feed ingredients and additives are initially mixed and fall into the collecting hopper 401. The feed ingredients enter the mixing inner cylinder 7 through the collecting hopper 401 and the conveying pipe 12. The drive motor 1301 drives the rotating shaft 801 and the spiral blade 802 to rotate, which moves the feed ingredients at the bottom of the mixing inner cylinder 7 upward and mixes the feed ingredients again. Some of the upward-moving feed was originally discharged from the discharge port 11, and some continued to move upward and finally fell from the discharge port 11 into the discharge chamber 9. The mixed feed ingredients enter the mixing hopper 21 and are discharged from the discharge pipe 10.
