AI Technical Summary
Traditional grain mixers use mixing blades that rotate in one direction, which causes the material to form a 'dead zone' in the container, resulting in insufficient mixing and affecting the uniformity of the mixture.
The agitator is driven to rotate circumferentially along the inner wall of the mixing tank and rotate on its own axis. Combined with the design of the tilting gear and the stirring rod, this ensures that the stirring blades can rotate circumferentially and on their own axis, thereby enhancing the mixing effect.
This process achieves more thorough mixing of grain raw materials, improves mixing uniformity, and avoids the occurrence of dead zones in the mixing process.

[0023] Example 1:
[0024] like Figures 1-3 As shown, a grain mixer includes a mixing drum 1, the upper end of which is open, and a discharge mechanism 2 is provided at the bottom of the outer side wall of the mixing drum 1; four support legs are fixedly connected to the bottom of the mixing drum 1, and the four support legs are arranged in an array along the circumference of the mixing drum 1.
[0025] A stirring mechanism, comprising a drive assembly 3 and an agitation assembly 5;
[0026] The driving component 3 is mounted on the mixing tank 1, and the stirring component 5 is mounted inside the mixing tank 1 and is distributed at intervals along the diameter of the mixing tank 1. The driving end of the driving component 3 is connected to the stirring component 5, and can drive the stirring component 5 to rotate circumferentially along the inner sidewall of the mixing tank 1, and can also drive the stirring component 5 to rotate on its own axis.
[0027] As a preferred embodiment, the drive assembly 3 includes a mounting frame 31, a motor 32, a rotating shaft 33, a gear disk 34, a driven gear 35, a stirring rod 36, a rotating plate 37, a ball 38, and a support plate 39.
[0028] The mounting bracket 31 is fixedly mounted on the mixing tank 1, the motor 32 is fixedly mounted on the top of the mounting bracket 31, and the gear disk 34 is fixedly connected to the mounting bracket 31 and located directly below the motor 32. Specifically, two connecting blocks 4 are fixedly connected to the top of the gear disk 34, and the top of the connecting blocks 4 is fixedly connected to the mounting bracket 31. Inclined teeth are provided on the outer peripheral wall of the gear disk 34. The drive end of the motor 32 passes through the mounting bracket 31 and the gear disk 34 in sequence and is fixedly connected to the inner end of the rotating plate 37 through the rotating shaft 33. The rotating plate 37 is in an inclined state, and the outer end of the rotating plate 37 is inclined downward.
[0029] The stirring rod 36 is rotatably sleeved on the rotating plate 37, the ball 38 is fixedly sleeved on the stirring rod 36 and located below the rotating plate 37, the support plate 39 is horizontally fixedly installed on the mounting frame 31, the inner end of the support plate 39 extends into the mixing tank 1, the ball 38 is rotatably sleeved inside the support plate 39, the driven gear 35 is fixedly connected to the upper end of the stirring rod 36, the driven gear 35 meshes with the gear disk 34, the stirring assembly 5 is installed at the lower end of the stirring rod 36 and located inside the mixing tank 1, when the motor 32 drives the rotating plate 37 to rotate, it can drive the stirring rod to rotate, thereby driving the gear to rotate along the outer peripheral wall of the gear disk 34.
[0030] The grain is poured into the mixing tank 1, and the motor 32 is started to drive the rotating shaft 33 to rotate the rotating plate 37. Since the ball 38 is rotated and sleeved in the support plate 39, the rotating plate 37 can drive the stirring rod 36 to rotate circumferentially around the outer wall of the gear disk 34. Since the driven gear 35 meshes with the gear disk 34 and the stirring rod is rotated and sleeved on the rotating plate 37, when the stirring rod rotates circumferentially, it drives the driven gear 35 to rotate around the outer wall of the gear disk 34. At the same time, the driven gear 35 rotates on its own axis around the axis of the stirring rod 36 under the action of the gear disk 34. This causes the stirring component 5 at the lower end of the stirring rod 36 to rotate circumferentially along the inner wall of the mixing tank 1 and also rotate on its own axis. This allows the stirring component 5 to more fully stir the grain in the mixing tank 1, ultimately making the different types or proportions of grain raw materials in the mixing tank 1 more evenly mixed.
[0031] As a preferred embodiment, the stirring assembly 5 includes a connecting rod 51 and a support rod 52. The upper end of the connecting rod 51 is fixedly connected to the lower end of the stirring rod 36. The support rod 52 has an inverted "L" shape, and several support rods 52 are arranged in a circumferential array on the outer peripheral wall of the connecting rod 51. The two ends of the support rod 52 are fixedly connected to the outer peripheral wall of the connecting rod 51 along the axial direction of the connecting rod 51. Specifically, in this embodiment, six support rods 52 are provided. By arranging the six support rods 52 in an array on the outer peripheral wall of the connecting rod 51, the stirring rod 36 drives the six support rods 52 to fully stir the grain raw materials in the stirring tank 1 when it drives the connecting rod 51 to rotate.
[0032] As a preferred embodiment, the unloading mechanism 2 includes a guide frame 21, a baffle plate 22, a guide plate 23, and a pull plate 24. A discharge port 11 is provided at the bottom of the outer wall of the mixing tank 1. The guide frame 21 is fixedly installed at the discharge port 11, covering the outside of the discharge port 11. The guide frame 21 is hollow and has an open upper end. Two guide plates 23 are provided and vertically fixedly connected to the inner bottom wall of the guide frame 21. The two guide plates 23 are located on both sides of the discharge port 11. The two guide plates 23 form a sliding gap with the outer wall of the mixing tank 1 to allow the baffle plate 22 to be inserted. The baffle plate 22 can slide vertically within the sliding gap between the guide plate 23 and the mixing tank 1. A pull plate 24 is fixedly connected to the upper end of the baffle plate 22. When it is necessary to stir the grain raw materials, hold the pull plate 24 to slide the baffle plate 22 downward into the sliding gap between the guide plate 23 and the mixing barrel 1 until the baffle plate 22 can seal the discharge port 11 of the mixing barrel 1. The inner side wall of the baffle plate 22 is in close contact with the outer side wall of the mixing barrel 1. After sealing the mixing barrel 1, pour in the grain raw materials for stirring. When it is necessary to unload after stirring, hold the pull plate 24 to pull the baffle plate 22 upward to open the discharge port 11 for easy unloading. The operation is convenient.
[0033] The working principle of this utility model is as follows:
[0034] In use, the baffle plate 22 is slid down into the sliding gap between the guide plate 23 and the mixing tank 1 by holding the pull plate 24 until the baffle plate 22 can seal the discharge port 11 of the mixing tank 1. The inner wall of the baffle plate 22 is in close contact with the outer wall of the mixing tank 1. After sealing the mixing tank 1, the grain raw materials are poured in for mixing. The motor 32 is started to drive the rotating shaft 33 to rotate the rotating plate 37. Since the ball 38 is rotated and sleeved in the support plate 39, the rotating plate 37 can drive the stirring rod 36 to rotate circumferentially around the outer peripheral wall of the gear disk 34. Since the driven gear 35 meshes with the gear disk 34 and stirs... The rod is rotatably mounted on the rotating plate 37. When the stirring rod rotates circumferentially, it drives the driven gear 35 to rotate around the outer peripheral wall of the gear disk 34. At the same time, the driven gear 35 rotates around the axis of the stirring rod 36 under the action of the gear disk 34. This causes the stirring component 5 at the lower end of the stirring rod 36 to rotate circumferentially along the inner side wall of the mixing tank 1 while also rotating on its own axis, so that the stirring component 5 can more fully stir the grain in the mixing tank 1. When it is time to unload after stirring, the hand pull plate 24 is used to pull the baffle plate 22 upward to open the discharge port 11 for easy unloading. The operation is convenient.
[0035] Example 2:
[0036] The remaining features of Example 2 are the same as those of Example 1, as shown in the appendix. Figure 4 As shown, the difference lies in that the stirring assembly 5 in Embodiment 2 includes a mounting rod 53, a fixing rod 54, an inner spiral stirring blade 55, and an outer spiral stirring blade 56. The upper end of the mounting rod 53 is fixedly connected to the lower end of the stirring rod 36. The inner spiral stirring blade 55 and the outer spiral stirring blade 56 are fixedly connected to the outer periphery of the mounting rod 53 by several fixing rods 54. The outer spiral stirring blade 56 is located on the outer periphery of the inner spiral stirring blade 55, and the spiral direction of the outer spiral stirring blade 56 is opposite to the spiral direction of the inner spiral stirring blade 55.
[0037] By setting inner spiral stirring blades 55 and outer spiral stirring blades 56 with opposite spiral directions, when the driven gear 35 drives the stirring rod to rotate around the axis of the stirring rod, the stirring rod drives the mounting rod 53 and the inner spiral stirring blades 55 and outer spiral stirring blades 56 on the mounting rod 53 to rotate, which will generate different flow directions, thereby increasing the relative movement between the grain raw materials, improving the stirring efficiency, ensuring that the grain raw materials are more fully mixed during the stirring process, and avoiding local accumulation or unevenness.
[0038] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
