Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for a sand mixer. Background Art

[0002] The agitator used in sand mixers is an important piece of industrial equipment, widely used in industries such as concrete, construction, chemicals, and metallurgy. As the core component of a sand mixer, the agitator is primarily used to mix various raw materials to achieve a uniform material state. Driven by an electric motor or other power source, the agitator rotates within the container, thereby mixing the materials. A mixing device typically consists of a mixing container, agitator, a transmission device, a support, and a control system. This device offers advantages such as uniform mixing, high efficiency, and ease of operation. Furthermore, the agitator speed and time can be adjusted to meet production needs, depending on the material and process requirements. It is widely used in industries such as concrete, construction, chemicals, and metallurgy to produce a variety of materials that require uniform mixing.

[0003] The prior art provides a portable mixing device for surface-touching mortar (Announcement No.: CN217670167U). This device includes a mixing tank, a lifting device provided at the bottom of the mixing tank, and a stirring device provided at the top of the mixing tank. The lifting device includes a mounting shell, the top of which is fixedly connected to the bottom of the mixing tank. A vertical motor is fixedly mounted on the inner bottom wall of the mounting shell, and the output shaft of the vertical motor is fixedly connected to a rotating shaft via a coupling. Two threaded rods are movably mounted on the inner bottom wall of the mounting shell, one end of which passes through and extends to the outside of the mounting shell. Synchronous belts are movably mounted on the outer surfaces of the two threaded rods and the outer surface of the rotating shaft. This portable mixing device for surface-touching mortar achieves the purpose of driving the stirring device up and down by providing a lifting device, facilitating cleaning of the mixing tank and scraper, preventing dust from flying, and preventing interference with stirring, thereby preventing the quality of the mortar from being affected.

When maintaining the stirring device, it is usually necessary to disassemble both the driving device and the stirring device, which is troublesome and inconvenient for rapid maintenance work. Therefore, we need to propose a stirring device for a sand mixer. Utility Model Content

[0024] A stirring device for a sand mixer comprises a mixing barrel 1, a barrel cover 2 being provided at the upper end of the mixing barrel 1, a motor 5 being provided at the bottom of the mixing barrel 1, an output end of the motor 5 passing through the mixing barrel 1 and fixedly connected to a square block 6, an outer side of the square block 6 being slidably connected to an auger 7, the auger 7 being rotatably connected to the mixing barrel 1, the upper end of the auger 7 being rotatably connected to a mounting tube 11, a fixing ring 13 being fixedly connected to the outer side of the mounting tube 11, two symmetrically distributed limit blocks 14 being rotatably connected to the outer side of the fixing ring 13, the upper ends of the two limit blocks 14 being fixedly connected to a connecting plate 15, the upper end of the connecting plate 15 being fixedly connected to a movable plate 16, a plurality of symmetrically distributed threaded holes 17 being opened at the upper end of the barrel cover 2, fixing bolts 18 being threadedly connected to the inner sides of the plurality of threaded holes 17, and the fixing bolts 18 being rotatably connected to the movable plate 16.

[0025] The barrel cover 2 is slidably connected to the connecting plate 15 and the movable plate 16 respectively. Two symmetrically distributed feed holes 3 are opened inside the barrel cover 2.

[0026] Exemplarily, the feed hole 3 facilitates the addition of raw materials into the interior of the mixing barrel 1 .

[0027] A discharge port is provided on the side wall of the mixing barrel 1 , and a sealing plate 4 is provided inside the discharge port.

[0028] For example, the sealing plate 4 seals the discharge port, which facilitates the discharge of the mixed raw materials from the mixing barrel 1.

[0029] The upper end of the auger 7 is fixedly connected to a connecting rod 8 , and the connecting rod 8 is rotatably connected to the mounting pipe 11 .

[0030] Exemplarily, the auger 7 installs the connecting rod 8 .

[0031] The upper end of the connecting rod 8 is fixedly connected to a gear 9 , and the gear 9 is rotatably connected to the mounting tube 11 .

[0032] Exemplarily, the connecting rod 8 mounts the gear 9 .

[0033] A gear ring 10 is meshed with the outer side of the gear 9 , and the gear ring 10 is fixedly connected to the mounting tube 11 .

[0034] Exemplarily, the gear 9 drives the gear ring 10 to rotate. Since the gear 9 and the gear ring 10 are in a meshing relationship, the gear ring 10 drives the mounting tube 11 to rotate in a certain direction.

[0035] A plurality of stirring rods 12 distributed in an annular manner are fixedly connected to the outer side of the mounting tube 11 .

[0036] Illustratively, the stirring rod 12 stirs the raw materials.

[0037] Working principle: When the present invention is used, the raw materials are injected into the mixing barrel 1 through the feed hole 3, and the motor 5 drives the auger 7 to rotate through the square block 6. The auger 7 lifts the raw materials at the bottom of the mixing barrel 1 to facilitate stirring the raw materials. When the raw materials are fully stirred, the auger 7 rotates and drives the gear 9 to rotate through the connecting rod 8. The gear 9 drives the gear ring 10 to rotate. Since the gear 9 and the gear ring 10 are in a meshing relationship, the gear ring 10 drives the mounting tube 11 to rotate in a certain direction. The mounting tube 11 drives the stirring rod 12 to stir the raw materials. During the rotation of the mounting tube 11, the limit block 14 limits the mounting tube 11 through the fixed ring 13. After the stirring is completed, the motor 5 is turned off, the sealing plate 4 is opened, and the stirred raw materials are discharged from the mixing barrel 1 through the discharge port.

The limit block 14 is stuck on the outside of the fixing ring 13. While limiting the mounting tube 11, it will not hinder the rotation of the mounting tube 11. At the same time, the barrel cover 2 limits the upper end of the mounting tube 11. The stirring device is installed through multiple limits, so that the stirring device can be disassembled separately during maintenance, reducing the workload of the disassembly work.
