Description

Technical Field

[0001] This utility model relates to the field of sand mixer technology, specifically to a high-efficiency and energy-saving sand mixer agitator structure. Background Technology

[0002] A sand mixer is a device that uniformly mixes the components in molding sand and effectively coats the sand particles with binder. The stirring paddles in existing sand mixers generally have a relatively simple structure. During rotation, they can only stir the sand particles in the mixer and cannot turn the sand particles up and down. The mixing efficiency of the sand particles needs to be improved. If a sand particle turning mechanism is added to the sand mixer, it is generally necessary to add a motor or other drive equipment. Although the mixing efficiency of the sand particles is improved, it is also easy to increase the energy consumption required for sand particle mixing. Therefore, there is an urgent need for a high-efficiency and energy-saving sand mixer stirring paddle structure. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a reasonably designed, high-efficiency, and energy-saving mixing paddle structure for sand mixers, thereby solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a drive shaft and a rotating frame. The drive shaft is rotatably mounted inside the sand mixer via bearings, and the drive shaft is connected to the output shaft of the drive motor of the sand mixer. The lower end of the drive shaft is fixedly fitted with a rotating frame, and the rotating frame is rotatably connected to the inner wall of the sand mixer via bearings.

[0005] It also includes:

[0006] The rotating rods, which are of several kinds, are rotatably inserted into the rotating frame through bearings with equal rounded corners. A No. 1 gear is fixedly sleeved on the rotating rod. An internal gear ring is fixedly installed on the inner wall of the sand mixer. The internal gear ring meshes with several No. 1 gears.

[0007] The stirring rod consists of several rods, which are rotatably inserted into several rotating rods via bearings. The rotating frame is equipped with a synchronous rotation mechanism connected to the several rotating rods. Two blades are fixedly mounted on the stirring rod.

[0008] A vertical rod is fixedly installed at the bottom of the rotating frame, and a lifting rod is provided at the lower end of the vertical rod. A stirring frame is fixedly sleeved at the lower end of the lifting rod.

[0011] The rotating shaft consists of several shafts, each movably inserted into several rotating rods. One end of the stirring rod is connected to the rotating shaft via a bevel gear pair. The upper end of the rotating shaft is fixedly fitted with a fourth gear that meshes with a third gear.

[0012] Furthermore, the diameters of gear 1 and gear 3 are the same, while the diameters of gear 2 and gear 4 are smaller than the diameter of gear 1.

[0013] Furthermore, the lifting rod is movably sleeved on the lower end of the vertical rod, and several connecting rods are rotatably connected to the outer ring wall of the lifting rod through universal joint bearings with equal rounded corners. One end of the connecting rod is rotatably connected to a rotating disk through a universal joint bearing, and the lower end of the driven shaft passes through the rotating frame and is fixedly connected to the rotating disk.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-4 As shown, the specific embodiment adopts the following technical solution: it includes a drive shaft 1 and a rotating frame 2. The drive shaft 1 is rotatably installed inside the sand mixer 3 through a bearing, and the drive shaft 1 is connected to the output shaft of the drive motor of the sand mixer 3. The lower end of the drive shaft 1 is fixedly sleeved with the rotating frame 2, and the rotating frame 2 is rotatably connected to the inner wall of the sand mixer 3 through a bearing.

[0025] It also includes:

[0026] Rotating rod 4, of which there are several, are rotatably inserted into rotating frame 2 via bearings with equal rounded corners. A first gear 5 is fixedly sleeved on the rotating rod 4. An internal gear ring 6 is fixedly installed on the inner wall of the sand mixer 3. The internal gear ring 6 meshes with several first gears 5. A baffle plate 16 is fixedly installed on the inner wall of the sand mixer 3 and is located below the rotating frame 2. The baffle plate 16 can protect the gap between the rotating frame 2 and the inner wall of the sand mixer 3, preventing sand particles from entering between the internal gear ring 6 and the first gear 5 and causing jamming.

[0027] The stirring rod 7 consists of several rods, which are rotatably inserted into several rotating rods 4 via bearings. The rotating frame 2 is equipped with a synchronous rotating mechanism 8 connected to the several rotating rods 4. Two blades 9 are fixedly installed on the stirring rod 7.

[0028] A vertical rod 10 is fixedly installed at the bottom of the rotating frame 2. A lifting rod 11 is provided at the lower end of the vertical rod 10, and a stirring frame 12 is fixedly sleeved at the lower end of the lifting rod 11.

[0029] The synchronous rotation mechanism 8 includes:

[0030] Driven shaft 8-1, there are several driven shafts 8-1, with equal rounded corners, rotatably passing through the rotating frame 2 via bearings. A second gear 8-2 that meshes with the first gear 5 is fixedly sleeved on the driven shaft 8-1. A third gear 8-3 is fixedly sleeved on the upper end of the driven shaft 8-1 after passing through the rotating frame 2.

[0031] Several rotating shafts 8-4 are movably inserted into several rotating rods 4. One end of the stirring rod 7 is connected to the rotating shaft 8-4 via a bevel gear pair. The upper end of the rotating shaft 8-4 is fixedly fitted with a fourth gear 8-5 that meshes with the third gear 8-3. When the rotating rod 4 rotates, driving the several stirring rods 7 to rotate within the sand mixer 3, the engagement of the second gear 8-2, the driven shaft 8-1, the third gear 8-3, and the fourth gear 8-5 enables the rotating shaft 8-4 to rotate within the rotating rods 4. The rotation within 4, simultaneously driven by the bevel gear pair, causes the stirring rod 7 to drive the blade 9 to rotate up and down, achieving the turning of sand particles within the sand mixer 3, making the mixing of sand particles more efficient. Gear 1 5 and Gear 3 8-3 have the same diameter, while Gear 2 8-2 and Gear 4 8-5 have smaller diameters than Gear 1 5. This allows the rotating shaft 8-4 to have a higher rotational speed than the rotating rod 4 when the rotating rod 4 and rotating shaft 8-4 rotate, ensuring efficient turning of sand particles. The lifting rod 11 is movable. The movable sleeve is located at the lower end of the vertical rod 10. Several connecting rods 13 are rotatably connected to the outer ring wall of the lifting rod 11 via universal joint bearings, with rounded corners at each end. One end of each connecting rod 13 is rotatably connected to a rotating disk 14 via a universal joint bearing. The lower end of the driven shaft 8-1 passes through the rotating frame 2 and is fixedly connected to the rotating disk 14. When the lifting rod 11 and the mixing frame 12 rotate within the sand mixer 3 to mix and stir the sand particles, causing the driven shaft 8-1 to rotate synchronously, the cooperation of the connecting rods 13 and the rotating disk 14 enables the lifting rod 11 and the mixing frame 12 to achieve the desired mixing and stirring effect. The up-and-down reciprocating movement of the mixing frame 12 enables the turning of sand particles in the lower middle of the sand mixer 3. A protective shell 15 is movably sleeved on the lifting rod 11 through a linear sealed bearing, and the protective shell 15 covers the connecting rod 13 and the rotating disk 14. The upper part of the protective shell 15 is fixedly connected to the rotating frame 2. The protective shell 15 can provide protection for the connecting rod 13 and the rotating disk 14, preventing the sand particles in the sand mixer 3 from contacting the connecting rod 13 and the rotating disk 14 during the mixing process, which would have an adverse effect on the up-and-down reciprocating drive of the lifting rod 11.

[0032] When using this invention, the motor of the sand mixer 3 drives the drive shaft 1 to rotate, the drive shaft 1 drives the rotating frame 2 to rotate, and the rotating frame 2 drives the rotating rod 4 to revolve within the sand mixer 3. The rotating frame 2 also drives the lifting rod 11 and the mixing frame 12 to rotate via the vertical rod 10. While the rotating rod 4 drives the mixing rod 7 and the impeller 9 to rotate within the sand mixer 3, it also meshes with the first gear 5 via the internal gear ring 6, causing the first gear 5 to rotate and drive the rotating rod 4 to rotate, thus improving the mixing efficiency of the mixing rod 7 and the impeller 9 on the sand particles. Simultaneously, the first gear 5 can drive the second gear 8-2 to rotate. The second gear 8-2 drives the driven shaft 8-1 to rotate, the driven shaft 8-1 drives the third gear 8-3 and the rotating disk 14 to rotate, the third gear 8-3 drives the fourth gear 8-5 to rotate, the fourth gear 8-5 drives the rotating shaft 8-4 to rotate, the rotating shaft 8-4 drives the stirring rod 7 to rotate through the transmission of the bevel gear pair, so that the stirring rod 7 can drive the blade 9 to turn the sand particles in the sand mixer 3 up and down. When the rotating disk 14 rotates, it can drive the lifting rod 11 and the stirring frame 12 to move up and down reciprocally through the connecting rod 13, and turn the sand particles in the middle of the lower part of the sand mixer 3.

[0033] Compared with the prior art, the beneficial effects of this utility model are:

[0034] Through the cooperation of gear 5 and internal gear ring 6, the rotating frame 2 can drive the rotating rod 4 to revolve within the sand mixer 3 while simultaneously rotating the rotating rod 4 on its own axis, thereby improving the mixing efficiency of the mixing rod 7 and the blade 9 on the sand particles.

[0035] With the cooperation of the synchronous rotation mechanism 8, the rotating rod 4 can rotate during its rotation, which in turn enables the stirring rod 7 to rotate, allowing the blade 9 to turn the sand particles inside the sand mixer 3 up and down, making the mixing of sand particles more efficient.

[0036] The protective shell 15 can provide protection for the connecting rod 13 and the rotating disk 14, preventing the sand particles in the sand mixer 3 from contacting the connecting rod 13 and the rotating disk 14 during the mixing process, which would have an adverse effect on the up-and-down reciprocating drive of the lifting rod 11.

[0037] The baffle plate 16 can protect the gap between the rotating frame 2 and the inner wall of the sand mixer 3, preventing sand particles from entering between the internal gear ring 6 and the first gear 5 and causing jamming.

[0038] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
