Description

Technical Field

[0001] The utility model relates to the technical field of feed preparation equipment, in particular to an auger for a feed crushing and mixing machine. Background Art

[0002] The feed used for raising chickens is made by crushing grains and mixing them with auxiliary materials. The patent with the application number 201410670012.5 discloses a dust-free feed crushing and mixing machine, including a mixing hopper. The bottom of the mixing hopper is a conical section. A screw conveyor is arranged in the mixing hopper. A crushing device is installed on the frame on one side of the mixing hopper. A first mixing device is also arranged at the bottom of the mixing hopper. The crushing device is connected to the inlet of the first mixing device through a feed pipe. The outlet of the first mixing device is communicated with the screw conveyor of the mixing hopper. An auxiliary material hopper is also arranged on one side of the bottom of the mixing hopper. The auxiliary material hopper is communicated with the screw conveyor through a second mixing device; a feed pipe is arranged on the crushing device, and a sleeve is arranged at the lower end of the feed pipe. The sleeve is sleeved outside the feed pipe to form a double-layer cavity; a return air pipe is arranged at the top of the first mixing device, and the return air pipe is communicated with the interlayer between the sleeve and the feed pipe through an auxiliary air pipe, and it can crush grains and mix them with other auxiliary materials to form feed. However, the part of the auger in the guide cylinder in the screw conveyor basically only plays the role of material transportation and less role in stirring and mixing, resulting in the need to improve the mixing efficiency. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an auger for a feed crushing and mixing machine aiming at the above existing technical deficiencies.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: an auger for a feed crushing and mixing machine, including a shaft body. A lower spiral blade is arranged at the lower part of the shaft body. An upper spiral blade is arranged at the upper part of the shaft body. The spiral directions of the lower spiral blade and the upper spiral blade are the same. The shaft body is also symmetrically provided with a plurality of stirring paddles about its axis. The stirring paddles are located in the guide cylinder in the mixing cylinder and between the lower spiral blade and the upper spiral blade.

[0005] As a preferred technical solution of the utility model, the stirring paddle is in a flat plate shape. The length direction of the stirring paddle is perpendicular to the axis of the shaft body. The width direction of the stirring paddle is parallel to the axis of the shaft body.

[0006] As a preferred technical solution of the utility model, a plurality of dispersing paddles are symmetrically arranged about the axis at the top of the shaft body.

[0007] As a preferred technical solution of the utility model, the dispersing paddle is in a flat plate shape. The length direction of the dispersing paddle is perpendicular to the axis of the shaft body. The dispersing paddle gradually inclines backward in the direction of its rotation from bottom to top.

[0008] Compared with the prior art, the utility model has the following advantages: 1. A lower helical blade and an upper helical blade are arranged on the shaft body, and a stirring paddle is arranged between the two. The stirring paddle can effectively stir the materials passing through the position where it is located, so as to improve the mixing efficiency after being installed on a feed crushing and mixing machine; 2. A dispersing paddle is also arranged on the upper part of the shaft body, which improves the dispersion range of the materials falling from the top of the draft tube, so as to further improve the mixing efficiency after being installed on a feed crushing and mixing machine.

[0012] To make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the utility model.

[0013] Detailed embodiments: As shown in Figure 1-2 An auger for a feed crushing and mixing machine includes a shaft body 1. A lower helical blade 2 is arranged at the lower part of the shaft body 1, and an upper helical blade 3 is arranged at the upper part of the shaft body 1. The helical directions of the lower helical blade 2 and the upper helical blade 3 are the same. A plurality of stirring paddles 4 are symmetrically arranged on the shaft body 1 with respect to its axis. In actual use, this auger is installed in a feed crushing and mixing machine. The stirring paddle 4 is located in a draft tube 7 (the draft tube 7 is fixed in the mixing cylinder 6 through a plurality of connecting rods) in the mixing cylinder 6 of the feed crushing and mixing machine and is located between the lower helical blade 2 and the upper helical blade 3. As shown in Figure 2As shown in the figure, when the auger rotates, the lower spiral blade 2 conveys the crushed grains, auxiliary materials at the bottom of the mixing cylinder 6 and the materials in the lower part of the mixing cylinder 6 upward into the guide cylinder 7. After the materials in the guide cylinder 7 are conveyed upward by the upper spiral blade 3, they fall into the mixing cylinder 6 from the top of the guide cylinder 7. The materials in the lower part of the mixing cylinder 6 will be conveyed upward by the auger to the top of the mixing cylinder 6 and then fall down continuously in a cycle. During this process, since the rotation speed of the materials is much lower than the rotation speed of the shaft body 1 (so that they can be pushed upward by the two spiral blades and conveyed upward), and the rotation speed of the stirring paddle 4 is the same as that of the shaft body 1, the stirring paddle 4 can effectively stir the materials passing through its position, thereby improving the mixing efficiency of the feed crushing and mixing machine.

[0014] Preferably, the stirring paddle 4 is in a flat plate shape. The length direction of the stirring paddle 4 is perpendicular to the axis of the shaft body 1, and the width direction of the stirring paddle 4 is parallel to the axis of the shaft body 1, which can push part of the materials to move around the shaft body 1.

[0015] Furthermore, a plurality of dispersing paddles 5 are symmetrically arranged about the axis of the shaft body 1 at the top of the shaft body 1. The dispersing paddles 5 are located above the guide cylinder 7 and are relatively close to the top of the guide cylinder 7. The dispersing paddles 5 rotate with the shaft body 1, which can expand the scattering area of the materials, thus having a better mixing effect.

[0016] Preferably, the dispersing paddle 5 is in a flat plate shape. The length direction of the dispersing paddle 5 is perpendicular to the axis of the shaft body 1, and the dispersing paddle 5 gradually inclines backward in the direction of its rotation from bottom to top, so that the materials slide down along the dispersing paddle 5 more slowly, and thus the scattering range is wider.

[0017] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
