Description

Mortar mixer

The utility model belongs to the device of making cement additive.

At the mortar mixer that construction site uses, because of the friction of revolution repeatedly of mortar, in the time soon, mortar just can pierce in the bearing that stirs main shaft, makes equipment accelerate damage during its work.General institute's asbestos packing that adopts or oil sealing carry out axle and seal, but all do not have certain effect, so must carry out a general overhaul after the civil engineering task is finished.If maintenance is not good at easier the appearance midway and is shut down situation to be repaiied, seriously influenced construction speed.In repair process, to change main shaft, multiple machine accessory such as bearing, expenses is big.The discharging mechanism of this machine system operation of manually shaking the hand in addition, during discharging because of main shaft in running, run into the effect of sandstone as blade, then occur handle easily and rebound and hurt sb.'s feelings.The mortar mixer that at present domestic many building machinery manufactory produces all exists the problems referred to above.

The utility model purpose provides a kind of main shaft seal dependable performance, can effectively prevent the mortar mixer of mortar to component wears such as main shafts.

The purpose of this utility model is achieved in that after motor is switched on and turns round that by the speed change step by step of belt pulley and reduction box, drive is mixed the interior stirring of a tube main shaft cutter and done circumference work.The output shaft of reduction box adopts inside and outside splined with the stirring main shaft.Mix cylindrical shell left side sliding bearing point on the excircle of output shaft of gear-box seat.Stirring main shaft and mixing a both sides wallboard centre junction and close the place, the two-sided dish type rubber seal that supports with in the stage clip work is installed, and by cast nylon lining ring and the inside and outside friction sealing of axle sleeve end face do that is set on the stirring main shaft.Because of mixing cylindrical shell both sides wallboard is blank weldering knot part, can not accurately guarantee and stir the perpendicularity of main shaft, passed through the dish type rubber seal such can self-adjusting soft junction structure, guaranteed the sealing property of friction contact surface.Discharging mechanism after the circumference action, makes the crank drivening rod of axle head make stretching motion by manually operated disk.Axle sleeve at the connecting rod other end, rotate on the fixedly pivot pin of cylindrical shell wallboard, make and mix cylindrical shell and can in operating process, change its angle, connecting rod with during crank two connects in the heart, designed to reach and mixed bent mouthful of two kinds of angle orientation self-lockings of tube when stirring and during discharging, rebound phenomena when preventing to operate, on the center chassis supporting-point of complete machine weight, be equipped with about the axletree fore shaft that can movable turn to each one pair, during transportation as the rubber-tired cart supporting-point, also has assembled by sleeve pipe the left and right sides, chassis can twitch two of the handle steel pipes of locating, and board can shrink back the handle steel pipe to the both sides, chassis behind the location.

The utility model has the advantages that:

1. owing to outside stirring main shaft axle sleeve is arranged, thereby main shaft is not easy to wear, only need change axle sleeve and periodic replacement nylon lining ring when overhaul, therefore greatly reduces maintenance cost.

2. simplified design on frame for movement greatly reduces manufacturing cost, and easy to maintenance.

3. the discharging mechanism operation is light, safe and reliable.

4. convenient transportation.

The utility model is described in further detail below in conjunction with drawings and Examples.
