Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment, and in particular to a feed crushing and mixing device. Background Technology

[0002] In the livestock farming industry, which combines modernization and large-scale operations, proper feed formulation and mixing are the core elements to ensure farming efficiency and livestock health.

[0003] Livestock feed is mainly divided into two categories: dry feed and wet feed. Dry feed is widely used in farms due to its advantages of easy storage and transportation, as well as the ease of controlling the amount fed. However, dry feed requires a strict and meticulous mixing process before feeding.

[0004] Currently, some farms still use the traditional manual mixing method, where workers repeatedly stir the feed pile with tools. However, manual mixing is extremely inefficient, especially when it comes to crushing and mixing feed.

[0005] In addition, some farms use feed crushing and mixing devices for crushing and mixing, such as existing technology, such as publication number: CN221132023U. This application provides a feed crushing and mixing device, including a shell, a pressure plate assembly, a cutter assembly, and a mixing assembly. The top of the shell is provided with a feed inlet and the bottom with a discharge outlet. The shell is provided with a first partition and a second partition. The first partition is higher than the second partition so that the shell forms a crushing chamber, a chopping chamber, and a mixing chamber from top to bottom. The first partition is provided with a first valve to connect the crushing chamber and the chopping chamber. The second partition is provided with a second valve to connect the chopping chamber and the mixing chamber. The pressure plate assembly is slidably connected in the crushing chamber to crush the feed. The crushed feed enters the chopping chamber through the first valve. The cutter assembly is rotatably connected in the chopping chamber. The rotation shaft of the cutter assembly extends in the horizontal direction. The chopped feed enters the mixing chamber through the second valve. The mixing assembly is rotatably connected in the mixing chamber. The mixed feed is discharged from the discharge outlet. This application can crush and chop agglomerated feed before mixing the raw materials, thus improving the mixing efficiency and effect. However, this technical solution also has room for improvement. The pressure plate component in the feed crushing and mixing device can only crush the feed intermittently, resulting in low crushing efficiency and affecting subsequent mixing processes. Therefore, there is room for improvement. Utility Model Content

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] A feed crushing and mixing device includes a housing 1, which contains a crushing chamber 2 and a mixing chamber 3. The mixing chamber 3 is cylindrical. The crushing chamber 2 contains a first crushing roller 4, a second crushing roller 5, and a third crushing roller 6 arranged in a triangular pattern. Each of the first crushing roller 4, the second crushing roller 5, and the third crushing roller 6 has triangular teeth 7. The mixing chamber 3 contains a mixing device, which includes a fixed cavity 8, a vertical rotating shaft 9, a horizontal rotating shaft 10, and a mixing motor 11. The fixed cavity 8 is fixed at the top center of the mixing chamber 3 by a left connecting column 12 and a right connecting column 13. The right connecting column 13 has a through hole that penetrates the outer wall of the housing 1, the right connecting column 13, and the inner wall of the fixed cavity 8. The horizontal rotating shaft 10 is rotatably connected to the through hole, with one end extending into the fixed cavity 8 and fixedly connected to a first bevel gear 14. The other end is fixedly connected to the output end of the mixing motor 11 via a coupling.

[0024] The upper end of the vertical rotating shaft 9 is connected to the bearing on the top wall of the fixed cavity 8 and is fixedly connected to the second bevel gear 15. The second bevel gear 15 meshes with the first bevel gear 14. The lower end of the vertical rotating shaft 9 extends to the fixed cavity 8 and extends to the lower end of the stirring and mixing cavity 3, and the lower end is fixedly connected to the stirring blade 16 at intervals.

[0025] Rotatable crushing plates 17 are provided on both sides of the first crushing roller 4, the second crushing roller 5 and the third crushing roller 6. The end of the crushing plate 17 facing the crushing roller is provided with crushing teeth 18, and the upper end of the crushing plate 17 is rotatably connected to the inner wall of the crushing chamber 2 through a rotating shaft 19. The side of the crushing plate 17 away from the crushing roller is connected to a universal joint 20, and the universal joint 20 is connected to a connecting rod 21.

[0026] A telescopic cylinder 22 is provided on the side of the housing 1, and the output end of the telescopic cylinder 22 is connected to the other end of the connecting rod 21 through a coupling.

[0027] The lower end of the mixing chamber 3 is provided with a discharge port 23, and a discharge valve is provided at the discharge port.

[0028] The upper end of the housing 1 is provided with a feed port 24.

[0029] The extension and retraction of the telescopic cylinder 22 can drive the crushing plate 17 to rotate along the rotating shaft 19.

[0030] The first crushing roller 4, the second crushing roller 5, and the third crushing roller 6 are connected to a transmission device, which includes a pulley, a belt, and a motor.

[0031] In this embodiment of the invention: Feed enters the crushing chamber 2 through the feed inlet 24. At this time, the first crushing roller 4, the second crushing roller 5, and the third crushing roller 6 begin to rotate under the drive of the transmission device (including pulleys, belts, and motors). These three crushing rollers are arranged in a triangle, and each has triangular teeth 7. When the feed falls between the crushing rollers, it is crushed by the squeezing action of the triangular teeth 7 on the crushing rollers. At the same time, the rotatable crushing plates 17 located on both sides of the crushing rollers also play an important role. The end of the crushing plate 17 facing the crushing roller has crushing teeth 18, and its upper end is rotatably connected to the inner wall of the crushing chamber 2 through a rotating shaft 19. The side away from the crushing roller is connected to the connecting rod 21 through a universal joint 20, and the other end of the connecting rod 21 is connected to the output end of the telescopic cylinder 22. Driven by the telescopic cylinder 22, the crushing plate 17 can rotate along the rotating shaft 19 and work in conjunction with the crushing roller. This greatly increases the contact area and crushing force between the feed and the crushing roller and crushing plate, enabling the feed to be crushed continuously and efficiently, effectively solving the problem of low crushing efficiency in the prior art.

[0032] The crushed feed falls into the mixing chamber 3, which is cylindrical and contains a mixing device. The mixing device includes a fixed chamber 8, a vertical rotating shaft 9, a horizontal rotating shaft 10, and a mixing motor 11. The fixed chamber 8 is fixed to the top center of the mixing chamber 3 via a left connecting column 12 and a right connecting column 13. After the mixing motor 11 is started, its output end drives the horizontal rotating shaft 10 to rotate via a coupling. One end of the horizontal rotating shaft 10 extends into the fixed chamber 8 and is fixedly connected to a first bevel gear 14. The first bevel gear 14 meshes with a second bevel gear 15 fixedly connected to the upper end of the vertical rotating shaft 9. Through this bevel gear transmission method, the rotational motion of the horizontal rotating shaft 10 is converted into the rotational motion of the vertical rotating shaft 9. The lower end of the vertical rotating shaft 9 extends into the fixed cavity 8 and then into the lower end of the mixing cavity 3. The lower end is fixedly connected with stirring blades 16 at intervals. As the vertical rotating shaft 9 rotates, the stirring blades 16 thoroughly mix the crushed feed, ensuring the uniformity of the feed and further improving the mixing effect of the feed.

[0033] Once the feed is fully mixed in the mixing chamber 3, the evenly mixed feed will flow out from the discharge port 23, thus providing evenly mixed feed for livestock farming.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
