Description

cement mortar mixer

The utility model relates to a stirring device.

In order to make my country's cement quality inspection closer to the international standard, my country will equivalently adopt the international standard ISO679-1989 as the standard of my country's cement strength test method. According to the requirements of this standard, the instruments used in the test should meet the basic structure and performance requirements of this standard. Under the condition that the performance and basic structure meet the requirements of this standard, each country can design the complete machine according to its own technical level. At present, there is no mixer suitable for this standard in China, and the imported machines are driven by belts, the precision is not ideal, and the structure of the motor, transmission box and main engine is not compact and reasonable.

The purpose of this utility model is to design a new type of cement mortar mixer, which uses worm gear and gear for transmission, and fixes the motor and transmission box on the main machine to make the structure compact, and the machine conforms to the ISO679-1989 standard for cement strength test requirements.

Accompanying drawing is the structural representation of the utility model.

As shown in the accompanying drawings, the utility model consists of a motor 1, a coupling sleeve 2, a worm screw 3, a sand tank 4, a sand drop port 5, a worm wheel 6, a gear I7, a main shaft 8, a gear II9, a transmission box 10, and an inner gear 11 , eccentric seat 12, planetary gear 13, stirring blade shaft 14, adjusting nut 15, stirring blade 16, stirring pot 17, support 18, base 19, handle 20, column 21, column flange 22 and locking device 23, etc. The flange 22 is integrated with the column 21, the locking device 23 is welded on the bottom of the stirring pot 17, the motor 1 and the transmission box 10 are fixed on the column flange 22, the output shaft of the motor 1 and the worm 3 Connected through the coupling sleeve 2, the worm 3 meshes with the worm wheel 6, the worm wheel 6 and the gear I7 are jointly fixed on a vertical shaft, the gear I7 meshes with the gear II9, the gear 9 is fixed on the main shaft 8, the worm wheel 6, the gear I7, and the gear II9 etc. are all in the transmission box 10, the lower part of the main shaft 8 is fixedly connected with the eccentric seat 12, one end of the eccentric seat 12 is connected with the stirring impeller shaft 14, and the upper end of the stirring impeller shaft 14 is fixedly connected with the planetary gear 13, and the planetary gear 13 and the internal gear The ring 11 is meshed, the lower end of the stirring blade shaft 14 is connected to the stirring blade 16 through the adjusting nut 15, the stirring pot 17 is connected to the support 18 through the locking device 23, the support 18 is connected to the column 21, and there is a handle 20 on the column 21. It is used for raising and lowering the support 18, the adjusting nut 15 can adjust the gap between the stirring blade 16 and the stirring pot 17, the rotating stirring pot 17 can remove the stirring pot 17 from the support 18, and the sand tank 4 is fixed on the top of the column 21. The bottom end is provided with a shakeout port 5, and the opening of the shakeout port 5 is located above the stirring pot 17.

As shown in the drawings, when the utility model works, the motor 1 transmits the power to the worm 3 in the transmission box 10 through the coupling sleeve 2, and then transmits the power to the gear I7 and the gear II9 through the worm wheel 6, and drives the main shaft 8 to rotate, and the main shaft 8 Drive the eccentric seat 12 to rotate, so that the stirring impeller shaft 14 connected to the eccentric seat 12 drives the stirring impeller 16 to revolve around the central axis of the stirring pot 17, and the planetary gear 13 on the upper end of the stirring impeller shaft 14 rotates around the inner The ring gear 11 rotates, thereby driving the stirring blade shaft 14 and the stirring blade 16 to rotate on its own. Add sand to the sand pot 4, and during the stirring process, the sand falls into the stirring pot 17 through the shakeout port 5 and is stirred together with the cement. When stirring automatically, the utility model follows the mixing program of ISO679-1989, that is: low speed for 30 seconds → low speed for 30 seconds and sand at the same time → high speed for 30 seconds → stop for 90 seconds → high speed for 60 seconds. During manual operation, the mixing program can be changed arbitrarily according to the needs.

The utility model has the advantages of simple structure, firmness and durability, convenient use, reliable operation, precise transmission and convenient maintenance.
