Description

Technical Field

[0001] The utility model relates to the technical field of breeding equipment, in particular to a feed mixer. Background Art

[0002] In the breeding industry, feed needs to be prepared and mixed evenly. The horizontal double-screw mixer is a commonly used feed mixer. The horizontal double-screw mixer of the prior art includes two blades with opposite spiral directions. Its structure is shown in the patent with application number 202021184319.1 and the name of "A Horizontal Mixer". When mixing, the outer layer of feed and the inner layer of feed flow in opposite directions. When reaching the end of the mixing bin, the original inner layer of feed becomes the outer layer and flows to the other end, and the original outer layer of feed becomes the inner layer and flows to the other end. In this process, there is a certain exchange between the inner and outer layers of feed. After a long period of stirring, the feed is mixed evenly. In this way, the exchange between the inner and outer layers of feed is relatively slight. Only when the feed reaches the edge of the mixing bin and the movement turns, the mixing is more intense, resulting in a longer mixing time. Utility Model Content

[0005] As a preferred technical solution of the utility model, a plurality of inner paddles are provided on the first spiral blade and the third spiral blade, and the inner paddles gradually move away from the stirring shaft from the front end in the rotation direction to the rear end in the rotation direction.

[0006] As a preferred technical solution of the utility model, a plurality of outer paddles are provided on the second spiral blade and the fourth spiral blade, and the outer paddles gradually approach the stirring shaft from the front end in the rotation direction to the rear end in the rotation direction.

[0008] As a preferred technical solution of the utility model, a circular arc insertion slot is provided on one side between the discharge pipe and the mixing barrel, and the circular arc insertion plate can be inserted into the insertion slot to close the upper end of the discharge pipe.

[0009] Compared with the prior art, the utility model has the following advantages: 1. A first spiral blade and a third spiral blade with opposite spiral directions are respectively arranged on both sides of the stirring paddle, a second spiral blade with opposite spiral direction is arranged outside the first spiral blade, and a fourth spiral blade with opposite spiral direction is arranged outside the third spiral blade, so that intense mixing can also occur in the middle of the mixing barrel, thereby improving the mixing efficiency and shortening the mixing time; 2. A plurality of inner paddles are arranged on the first spiral blade and the third spiral blade, and a plurality of outer paddles are arranged on the second spiral blade and the fourth spiral blade, thereby improving the degree of exchange between the inner and outer layers of feed, thereby improving the mixing efficiency.

[0015] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0016] Specific implementation method: Combination Figure 1-4As shown, a feed mixer comprises a frame 1, on which a mixing barrel 2 is arranged, and the lower part of the cross-section of the mixing barrel 2 is semicircular, and a stirring paddle 3 driven by a power system to rotate is arranged in the mixing barrel 2, and a discharge pipe 21 which can be opened and closed is arranged on the lower side of the mixing barrel 2, and a first spiral blade 32 is arranged on one side of the stirring paddle 3, and a third spiral blade 34 with a spiral direction opposite to that of the first spiral blade 32 is arranged on the other side of the stirring paddle 3, and a second spiral blade 33 with a spiral direction opposite to that of the first spiral blade 32 is arranged on the outside of the first spiral blade 32, and a fourth spiral blade 35 with a spiral direction opposite to that of the third spiral blade 34 is arranged on the outside of the third spiral blade 34, and the four spiral blades are located at one end of the middle part of the stirring shaft 31, and are preferably on the same plane. During stirring, the two spiral blades located at the outer layer push the feed from the two ends of the mixing barrel 2 to the middle. When the feed reaches the middle of the mixing barrel 2, it collides and mixes violently. At the same time, the two spiral blades located at the inner layer push the feed in the middle of the mixing barrel 2 to the two ends. When the feed reaches the two ends of the mixing barrel 2, it changes direction and mixes violently. In this process, the inner and outer layers of feed also exchange to a certain extent. Since violent mixing also occurs in the middle of the mixing barrel 2, the mixing efficiency is improved and the mixing time is shortened.

[0017] Furthermore, the first spiral blade 32 and the third spiral blade 34 are provided with a plurality of inner paddles 37, and the inner paddles 37 are arranged in the rotation direction thereof ( Figure 4 The front end of the stirring shaft 31 gradually moves away from the stirring shaft 31 to the rear end of the stirring shaft 31 in the rotation direction, so that the inner paddle 37 can push a part of the inner layer feed to the outer layer during rotation, thereby improving the degree of exchange between the inner and outer layers of feed.

[0018] Furthermore, the second spiral blade 33 and the fourth spiral blade 35 are provided with a plurality of outer paddles 36, and the outer paddles 36 are arranged in the rotation direction thereof ( Figure 4 The front end of the mixing plate 36 (clockwise rotation in the figure) gradually approaches the stirring shaft 31 to the rear end in the rotation direction, so that the outer paddle 36 can push a part of the outer layer feed to the inner layer during rotation, thereby improving the degree of exchange between the inner and outer layers of feed.

[0019] Specifically, the power system includes a reducer and a motor transmission-connected thereto.

[0020] Preferably, a circular arc-shaped slot is provided on one side between the discharge pipe 21 and the mixing barrel 2, and the circular arc-shaped insert plate 22 can be inserted into the slot to close the upper end of the discharge pipe 21. After the mixing is completed, the insert plate 22 is pulled outward, and the stirring paddle 3 keeps rotating to push the outer layer of feed toward the middle of the mixing barrel 2, so that the feed in the mixing barrel 2 can be discharged.

[0021] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only preferred examples of the utility model, and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
