Drive device, described drive device comprises motor and the pinion gear that is arranged on motor output shaft, and described pinion gear meshes with two big gears respectively, and two big gears are respectively arranged on two stirring shafts, and described The stirring shaft is supported on the support by a pressure bearing, the two stirring shafts are arranged vertically and parallelly, each stirring shaft is provided with 2-4 rows of stirring blades, each row has at least two stirring blades, The stirring blades are all right-angled trapezoids, the right-angled sides of the stirring blades are close to the central axis of the stirring shaft and arranged parallel to the stirring shaft, the short bottom edge of the stirring blades is arranged on the top, and the beveled sides of each row of stirring blades are from the Located on the same oblique line from top to bottom, the two stirring shafts start from the position where the first stirring blade is set at the upper end to the end of the stirring shaft, showing a conical shape with a large top and a small bottom; in each row of stirring blades, The two stirring blades located at the bottom are provided with waist-shaped holes whose centerlines are inclined toward the central axis of the stirring shaft.

Further, the area of each waist-shaped hole is one-fourth or one-fifth of the area of the stirring blade where it is located.

Further, the mixing box is set on a base, and a column is arranged on the base, and one side of the motor is supported on the column.

Further, four universal wheels are provided at the bottom of the base, a driving handrail is provided on one side of the base, and a driving device protective cover is also provided on the support.

Beneficial effect:

According to the present invention, a driving device is arranged above the stirring box, and simultaneously drives two vertically arranged stirring shafts to drive the stirring blades for stirring. The hypotenuses of multiple stirring blades in the same row are on the same oblique line, and waist-shaped holes are set on the stirring blades located below, so that the longer stirring blades are set at the bottom to ensure a larger area of stirring, while the upper ones are set The shorter mixing blades can use the inertia of the lower mortar to achieve a larger mixing area while stirring. The present invention can also save materials and energy consumption under the condition of improving stirring efficiency and stirring uniformity.

The conical stirring shaft with a large top and a small bottom can ensure sufficient stirring strength at the root of the stirring shaft, thereby improving the reliability and service life of the present invention.

In addition, since the bottom of the mixing box is set as a curved surface, it is easy to clean, and it is equipped with universal wheels, which is easy to move and can improve its utilization rate.

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Detailed ways

As shown in the figure, a mortar mixer includes a mixing box 3, and the bottom of the mixing box is designed as an arc surface, so as to facilitate cleaning.

The upper end of the mixing box 3 is provided with an opening, and the lower part of the mixing box 3 is provided with a discharge port 13 and a sewage outlet 14.

A support 12 is provided on the opening of the stirring box 3, and a drive device is provided on the support 12, and the drive device includes a motor 10 and a pinion 11 arranged on the output shaft of the motor.

The pinion 11 is meshed with two large gears 9 respectively, and the two large gears 9 are respectively arranged on two stirring shafts 6, and the stirring shaft 6 is supported on the support 12 through the pressure bearing 7, and the two large gears 9 are respectively arranged on the two stirring shafts 6. The stirring shafts are vertically arranged in parallel, and each stirring shaft is provided with 2-4 rows of stirring blades 5, and each row has at least two stirring blades.

The number of rows of stirring blades arranged on the two stirring shafts is the same, and the number of each row is also the same.

The stirring blades are all right-angled trapezoids, the right-angled sides of the stirring blades are close to the central axis of the stirring shaft and arranged parallel to the stirring shaft, the short bottom edge of the stirring blades is arranged on the top, and the beveled sides of each row of stirring blades are from the From top to bottom lie on the same oblique line, that is to say, the hypotenuses of the orthographic projections of multiple stirring blades in the same column are located on the same oblique line.

The two stirring shafts start from the position where the first stirring blade is set at the upper end to the end of the stirring shaft, and are conical in shape with a large top and a small bottom.

In this embodiment, each stirring shaft is provided with two rows of stirring blades, the two rows of stirring blades are arranged symmetrically with respect to the center line of the stirring shaft, and each row contains four stirring blades. In each row of stirring blades, the two bottommost stirring blades are provided with a waist-shaped hole 8 whose center line is inclined toward the central axis of the stirring shaft.

In this way, when the motor rotates in the direction of the corresponding arrow as shown in the figure, the two large gears 9 drive the two stirring shafts to rotate in the direction opposite to the direction of rotation of the motor 10, thereby stirring the mortar. The combined force of the two stirring shafts can stir more materials.

The waist-shaped hole 8 can reduce the resistance during the stirring process and improve the stirring effect.

In order to ensure the strength of the stirring blade itself while ensuring the stirring effect, the area of each waist-shaped hole is preferably 1/4 or 1/5 of the area of the stirring blade where it is located

The mixing box 3 is arranged on a base 2, and a column 15 is arranged on the base 2, and one side of the motor 10 is supported on the column 15.

The bottom of the base 2 is provided with four universal wheels 1 , and a driving handrail 4 is provided on one side of the base 2 . Such a structure can be moved conveniently, which increases the convenience of use of the present invention.

In order to protect the driving device from dust and rain, a driving device protective cover 16 is also provided on the support.
