Abstract

The utility model relates to an improved structure of an agitator. The improved structure comprises a base plate, a stirring mechanism, a transmission mechanism, a feed mechanism, a control electrical appliance and the like, wherein a rotating shaft of a driving gear is in transmission connection with an output shaft of a speed reducer; the speed reducer and a motor are fixed integrally; an input shaft of the speed reducer is in transmission connection with a rotating shaft of the motor; the rear end of the rotating shaft of the motor can be buckled and connected with a plug of a crank in a movable mode. According to the improved structure, the rotating shaft of the motor is in transmission connection with the input shaft of the speed reducer directly, so that the size of the transmission mechanism can be reduced, the maintenance-free characteristic can be realized, and the production cost is reduced. In addition, the rotating shaft of the motor is driven by utilizing the crank, so that the problem of halting due to power failure can be solved, and the normal operation and discharging of the agitator are ensured. The improved structure is simple and reasonable, easy to produce and install, low in cost and good in effect, and is easy to popularize and implement.

Description

Mixer improves structure

Technical field

The utility model relates to concrete stirring technique field, is specifically related to a kind of mixer and improves structure.

Background technology

At present, bipyramid counter-rotating discharging mobile concrete mixer can stir plasticity and half-dried rigid concrete, and mixing drum is just changeing stirring, and the counter-rotating discharging is applicable to the common buildings building site, road, science of bridge building and various concrete component factory.

Existing mixer partly is made up of rabbling mechanism, transmission mechanism, feed mechanism, chassis, electrical equipment etc.; Transmission mechanism comprises bull gear and the driven wheel that is arranged on the mixing drum; The driven wheel of existing mixer is installed on the speed reducer output shaft; Be respectively arranged with belt pulley on reductor power shaft and the motor output shaft, two belt pulleys connect through belt transmission.Because belt has certain retractility, the position relation of reductor and motor requires accurately, takies to add large space, and belt has elongation trend when using, and causes its service life short, falls band and broken belt easily, and service life is short, installs and change very trouble.

Summary of the invention

The utility model improves the problem and shortage that structure exists to existing mixer, provides a kind of transmission mechanism is carried out improved mixer improvement structure.

Technical scheme: a kind of mixer improves structure, comprises that chassis, rabbling mechanism, transmission mechanism, feed mechanism and control are electric, wherein; Said rabbling mechanism comprises horizontally-mounted mixing drum; The one or both ends of mixing drum are provided with endless track, and two fixing on each endless track and the chassis symmetrical support rollers cooperate installation, and a side of mixing drum is provided with annular gear ring; The driven wheel engaged transmission of this annular gear ring and transmission mechanism; The rotating shaft and the speed reducer output shaft of driven wheel are in transmission connection, and reductor and motor are fixed as one, and the power shaft and the machine shaft of reductor are in transmission connection.

Simultaneously, the rear end cap of motor is provided with centre bore, and the diameter of this centre bore is greater than the diameter of machine shaft, and the plug of crank can mate in this centre bore of insertion; The rear end of machine shaft and the plug of crank can be movable to buckle.

The rear end of machine shaft is provided with keyway, and the plug of crank is provided with the jack with the machine shaft coupling, is provided with the key with said keyway coupling in the jack.

Beneficial effect: 1, the utility model is through improving transmission mechanism; Adopt reductor and motor integral structure; Utilize machine shaft directly to be in transmission connection, need not consider that the distance relation of reductor and motor and position concern, not only can dwindle the volume of transmission mechanism with the reductor power shaft; And can realize non-maintaining characteristics, thereby reduce production costs.

2, in addition, utilize the rotating shaft of crank drive motors can overcome, guarantee mixer operate as normal and discharging because of power failure causes halting problem.

3, it is simple and reasonable after the utility model transformation, produces easily and installs, and cost is low effective, is beneficial to very much promotion and implementation.
