Description

Technical Field

[0001] This utility model relates to the field of forage processing technology, and more specifically, to a forage mixer. Background Technology

[0002] Forage is diverse, mainly including roughage, concentrate, succulent feed, animal feed, mineral feed, and feed additives. Roughage refers to feed with a crude fiber content of 18% or more in dry matter, and mainly includes four types: hay, straw, green fodder, and silage. Examples include hay such as wild hay, sheep grass, ryegrass, and alfalfa; straw such as corn stalks, rice straw, and millet straw; green fodder such as wild grass, green barley, and green alfalfa; and silage made from green fodder or green crop straw through lactic acid fermentation.

[0003] After searching, it was found that application number CN202320806494.7, entitled "A Mixer for Cattle and Sheep Feed Production," uses two spiral plates to mix feed, improving work efficiency. However, with the continuous advancement of cattle breeding technology, cattle and sheep farms generally use a mixture of roughage and concentrate to prepare feed. During preparation, because roughage is mostly straw, which is long and bulky, it is not easy to mix evenly with pelleted or powdered concentrate. At the same time, because roughage has long fibers, it is also easy to tangle during mixing, requiring cattle and sheep to spend a long time chewing, affecting feeding efficiency. Further improvements can be made.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a feed mixer, which has the advantages of improved ease of use and work efficiency, thereby solving the problems mentioned in the background technology.

[0006] (II) Technical Solution To achieve the aforementioned advantages of improved ease of use and work efficiency, the specific technical solution adopted by this utility model is as follows: A feed mixer includes a mixing drum and a mixing shaft. A base is fixedly installed on the bottom surface of the mixing drum, and a coupling is fixedly installed inside the base. A drive motor is connected to the input end of the coupling, and a mixing shaft is installed at the output end of the coupling. The mixing shaft passes through the bottom surface of the mixing drum and extends into the interior of the mixing drum. Spiral blades are welded to the outer surface of the mixing shaft, and cutters are welded to the edges of the spiral blades.

[0007] Furthermore, a conveyor is installed on one side of the mixing tank.

[0008] Furthermore, a discharge port is provided on the bottom surface of the mixing tank, and an installation base is welded above the discharge port on the outer wall of the mixing tank. An electric cylinder is fixedly installed on one side of the installation base, and a baffle is fixedly installed on the other end of the moving rod of the electric cylinder.

[0009] Furthermore, a connecting plate is fixedly installed at one end of the baffle, and the connecting plate is fixedly connected to the other end of the moving rod of the electric cylinder.

[0010] Furthermore, the baffle adopts an arc-shaped structure, and the baffle is located outside the discharge port, and the baffle slides against the outer wall of the mixing tank.

[0011] Furthermore, a side hopper is welded to the outer side of the baffle on the outer wall of the mixing tank, and the bottom and top surfaces of the side hopper are both open structures.

[0012] Furthermore, the cutter has a triangular structure and is evenly distributed along the edge of the spiral blade.

[0013] Furthermore, a controller is fixedly installed on the other side of the mixing tank, and an observation platform is mounted on the back side of the mixing tank.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a feed mixer, which has the following beneficial effects: (1) This utility model adopts a spiral blade and a cutter. The edge of the spiral blade is welded with a cutter. When mixing feed, straw and pellets can be put into the mixing tank, the drive motor is started, and the mixing shaft is driven to rotate through the coupling, which drives the spiral blade to rotate and mix the feed. At the same time, the rotation of the spiral blade drives the cutter to rotate and cut the straw, reducing the straw length, making it easier to mix evenly with the pellet feed. It is also easier for cattle to eat and improves work efficiency. At the same time, the cutter makes the feed finer, improves the uniformity of mixing, and avoids clumping.

[0015] (2) This utility model adopts a side-opening discharge port. After the mixing is completed, the operator can start the electric cylinder to pull the baffle up and open the discharge port.

[0019] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, a feed mixer is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Please refer to them. Figure 1 and Figure 2 According to an embodiment of the present invention, the feed mixer includes a mixing tank 1 and a mixing shaft 5. The mixing tank 1 is a cylindrical metal tank with thick walls and good wear resistance. A base 2 is fixedly installed on the bottom surface by bolts. The base 2 is a frame-type metal structure that supports the mixing tank 1. A coupling 4 is bolted to the inside of the base 2. The coupling 4 reduces the rotational speed and increases the torque. The input end is connected to the drive motor 3 via the coupling. The drive motor 3 is a three-phase asynchronous motor that provides stirring power. The output end of the coupling 4 is connected to the stirring shaft 5 via the coupling. This is a common drive connection method and will not be described in detail here. The stirring shaft 5 passes through the bottom surface of the stirring tank 1 and extends into the interior of the stirring tank 1. A sealed bearing is installed at the connection point with the bottom surface of the stirring tank 1 to prevent feed leakage. The top surface of the stirring shaft 5 and the spiral blade 6 is a conical structure, which can prevent feed from accumulating on the top of the shaft. The spiral blade 6 is welded to the outer surface of the stirring shaft 5. The spiral blade 6 spirals upward along the stirring shaft 5, which can turn the feed at the bottom upward. The spiral blade 6 is welded with a cutter 7. The cutter 7 is a high-strength alloy blade with a sharp cutting edge on its surface. The weld between the cutter 7 and the spiral blade 6 is polished to prevent the weld from protruding and getting stuck in the feed. When mixing feed, workers can put straw and pellets into mixing drum 1, start drive motor 3, and the motor power is transmitted to mixing shaft 5 after being reduced in speed by coupling 4, which drives mixing shaft 5 and spiral blades 6 to rotate. When spiral blades 6 rotate, they can not only mix the feed, but also push the feed at the bottom upwards, so that the feed at the top and bottom layers are fully mixed. The arrangement of spiral blades can reduce feed residue and improve the cleaning effect. At the same time, the rotating spiral blade 6 drives the cutter 7 to rotate at high speed. When the cutter 7 comes into contact with the straw, it uses its sharp blade to cut the straw into short sections, reducing the straw length so that it can be mixed more evenly with the pellet feed. At the same time, the short straw is also easier for cattle and sheep to eat, improving the efficiency of mixing and processing.

[0022] A dust removal device can be installed on the top surface of the mixing tank to reduce dust spillage and improve the cleanliness of the working environment. This is a common device in the field and is not shown in the figure. Please refer to Figure 1 and Figure 2 A conveyor 13 is mounted on one side of the mixing tank 1. The conveyor 13 is a belt conveyor with anti-slip texture on the surface of the conveyor belt, which facilitates the transportation of the mixed feed to the designated location and reduces the amount of manual handling work. Please refer to Figure 1 and Figure 3 A discharge port 12 is provided on the bottom surface of the mixing tank 1. The discharge port 12 is a rectangular opening located on the side wall of the mixing tank 1 near the bottom. Above the discharge port 12, on the outer wall of the mixing tank 1, a mounting base 8 is welded. The mounting base 8 is a metal bracket, and an electric cylinder 9 is fixedly mounted on one side surface by bolts. The electric cylinder 9 is a linear drive device, and a baffle 10 is fixedly mounted on the other end of its moving rod by a connecting plate 15.

[0023] After mixing is complete, the operator can activate the electric cylinder 9 via the controller 14. The moving rod of the electric cylinder 9 retracts, pulling the baffle 10 upward and opening the discharge port 12. The mixed feed is discharged from the discharge port 12 under the continuous stirring and pushing of the spiral blades 6, falling onto the conveyor belt of the conveyor 13. After passing through the conveyor 13, it can be transported to the next processing station, eliminating the trouble of manual unloading and further improving the convenience of use and work efficiency. Please refer to Figure 1 and Figure 3 A connecting plate 15 is welded and fixedly installed on one end of the baffle 10. The connecting plate 15 is a metal plate, and the connecting plate 15 is fixedly connected to the other end of the moving rod of the electric cylinder 9 by fixing bolts. The connecting plate 15 increases the connection area between the electric cylinder 9 and the baffle 10, making it easier for the two to be firmly connected and preventing the baffle 10 from falling off during movement. Please refer to Figure 1 and Figure 3 The baffle 10 adopts an arc-shaped structure that matches the curvature of the outer wall of the mixing tank 1, and the baffle 10 is located outside the discharge port 12. The baffle 10 slides against the outer wall of the mixing tank 1, and the two fit tightly together. When mixing feed, the baffle 10 is pushed by the electric cylinder 9 to tightly seal the discharge port 12, preventing feed from leaking from the discharge port 12 during the mixing process. Please refer to Figure 1 and Figure 4 A side hopper 11 is welded to the outer wall of the mixing tank 1 on the outside of the baffle 10. The side hopper 11 is a metal hopper with baffles on both sides and an open structure on the bottom and top. The width of the side hopper 11 is smaller than the width of the conveyor belt of the conveyor 13, and the side hopper 11 is located above one end of the conveyor 13. The feed discharged from the discharge port 12 first falls into the side hopper 11. The side hopper 11 can concentrate and guide the feed, so that the feed falls accurately onto the conveyor belt of the conveyor 13, avoiding the waste caused by the scattering of feed. Please refer to Figure 1 The cutter 7 has a triangular structure, which enhances the strength of the blade. The cutters 7 are evenly spaced along the edge of the spiral blade 6, allowing multiple cutters 7 to work simultaneously, thus improving the cutting efficiency of straw. The cutters 7 and the spiral blade 6 are made of the same metal material, ensuring consistent strength after welding and preventing breakage.

[0024] Please refer to Figure 1 and Figure 2 On the other side of the mixing tank 1, a controller 14 is fixedly installed on the front facade by bolts. The controller 14 has operation buttons and a display screen on its surface, which makes it convenient for operators to start and stop the drive motor 3, electric cylinder 9 and conveyor 13, and can also display the operating status of the equipment. An observation platform is set on the rear facade of the mixing tank 1, and there are handrails on both sides of the observation platform, which makes it convenient for operators to climb to the top of the mixing tank 1 to feed materials and perform equipment maintenance. Working principle: When mixing the feed, workers climb to the top of the mixing tank 1 via an observation platform and add straw and pellets into the mixing tank 1 according to the specified ratio. This also facilitates maintenance and observation of the mixing process. The drive motor 3 is started via the controller 14, and the drive motor 3 drives the mixing shaft 5 to rotate via the coupling 4. The mixing shaft 5 then drives the spiral blades 6 and the cutter 7 to rotate. When the spiral blade 6 rotates, it turns the feed up and down, so that the straw and pellets are initially mixed; at the same time, the cutter 7 rotates at high speed to cut the straw, cutting the long straw into short segments. As the mixing continues, the short straw and pellets are gradually mixed evenly. After mixing is complete, the operator stops the drive motor 3 via controller 14 and simultaneously starts the electric cylinder 9 and conveyor 13. The electric cylinder 9 pulls the baffle 10 upward, opening the discharge port 12; the conveyor 13 starts running, and the conveyor belt moves forward. Then, the drive motor 3 is started again (running at low speed), and the spiral blades 6 push the mixed feed towards the discharge port 12. The feed is discharged through the discharge port 12 and falls into the side hopper 11, from which it is guided onto the conveyor belt of the conveyor 13 and transported to the next processing station. After all the feed is discharged, the drive motor 3, electric cylinder 9 and conveyor 13 are turned off by the controller 14. The electric cylinder 9 pushes the baffle 10 down to re-seal the discharge port 12, completing one mixing operation. This feed mixer integrates mixing, cutting, and conveying functions, with a high degree of automation. It can efficiently mix straw and pellets evenly, while facilitating unloading and conveying, greatly improving the efficiency and convenience of feed processing.
