Abstract
The utility model discloses an improved agitator for cement mortar which belongs to the special equipment of the physical property checking of the cement. The utility model comprises a motor, a drive mechanism, an agitating device, a lifting device and a controller. By using a worm wheel and a worm speed reducer, the drive mechanism drives a planet device to make an agitating vane realize revolution and autorotation in a caldron; so the cement mortar which is agitated can realize sufficient and homogeneous degree, and the accuracy degree of the cement checking can be improved. The utility model has the advantages of small size, beautiful appearance and convenient operation.
Description
The utility model relates to a kind of improvement of cement paste mixer, belongs to the special equipment of cement physical properties check.
China's current standard " GB1346-77 cement normal consistency water consumption, setting time, the stability method of inspection " the middle mixer of stipulating use, stirring vane can only rotation, in pot, repeating identical track on the clean slurry at a certain position, thereby stir inhomogeneous, this is the plane in the bottom of a pan, and the easy sizing in pot limit can not satisfy the requirement of test.
The mixer of the orbital path that adopts usually is cement paste and the dual-purpose mixer of mortar in the world, its transmission system is that the driven by motor little tooth difference speed reducer drives the planet device again, the diameter 202mm of pot, volume 5 liters, when carrying out China's GB, if only be used for stirring clean slurry, the volume that then seems is excessive and heavy, and little tooth difference speed reducer is made complicated, need accurate machined, the manufacturing cost height, inconvenient maintenance, the control mode of Cai Yonging is to use the minitype motor driving gear drive in the world, the working time and the duty of control mixer, its shortcoming is to make difficulty, cost height, not easy-maintaining; The lowering or hoisting gear of the agitated kettle of Cai Yonging is in the world: cooperate with negative and positive two slide rails, friction is moved up and down, and the frictional resistance of this structure is big.
Task of the present utility model is a kind of suitable China's national situation of design, and the small-sized clean slurry mixer of close international standard, stirring vane is done planetary rotation, energy rotation and revolution, and rotary motion trace spreads all over pot interior each position, and do not repeat, stir, good stability, elevating mechanism are taked to contact with steel ball between two slide rails, steel ball rolls between slide rail, thereby realizes that two slide rails move up and down; Control loop and major loop that automatic control system is formed with auxiliary reclay and transistor time relay form the electrical equipment programme-control, thus the working time and the duty of control mixer.Automatically control is malfunctioning for prevention simultaneously, and this machine also has manual overvide.
Fig. 1 is the overall construction drawing of the utility model cement paste mixer, mainly by motor 4, and transmission mechanism 6, stirring vane 8, agitated kettle 7, lowering or hoisting gear 2, pillar 1, support 3, outer cover 5 and controller 18 are formed.
That is: behind the motor rotation, through the cooperating of worm gear, worm reducer 10 and planetary driving device, paddle has been finished the action of rotation and revolution simultaneously.
The fit clearance of agitated kettle and paddle (Fig. 3) is 1 ± 0.2mm, and the diameter of agitated kettle is φ 160mm, and H140mm, volume are 2.5 liters.The profile camber line of paddle and the inner surface camber line of agitated kettle are corresponding, and the radius of paddle is 55.6mm, and leaf is 22.8mm with the off-centre of pot, so the outward flange of paddle will be crossed the center 32.8mm of agitated kettle, stir sufficient purpose thereby reach.
Lowering or hoisting gear (Fig. 4) is by handlebar, and pot holds in the palm 14, shift fork 15, and rotating disk 16 and guide rail 13 are formed.
The installation that interfixes of handlebar 12, rotating disk 16, shift fork 15, an end of shift fork 15 is a through hole, and an end is an open slot, and the centre bore of the centre bore of rotating disk 16 and shift fork 15 is fixed on the same rotating axle, and handlebar is fixed on the rotating disk; Pot holder 14 mainly is made up of pot holder guide rail, pot holder support, sliding axle 17, and pot holder guide rail will match with the guide rail 13 on being installed in instrument support 3 during work, and rotatable steel ball is arranged between two guide rails, makes pot ask 14 to move up and down along the guide rail direction.Sliding axle 17 is installed in the open slot of shift fork 15, move the handle dial rotation then shift fork rotate simultaneously.Be installed in the pot holder sliding axle in the shift fork open slot this moment, can not rotate, can only slide, thereby give the pot holder power up or down, impel pot holder 14 to move up or down along track by shift fork along open slot with shift fork.
In the middle of the track of pot holder track and instrument support rolling steel ball is installed, the resistance when making the pot holder mobile reduces greatly, and the upper and lower activity of energy freely.
Accompanying drawing 5 is the electrical equipment Automatic Control Theory figure of mixer controller, consists of the following components: 1. auxiliary reclay JZ7-44
, the 2. time relay
3. power transformer B220V/63V, and power switch, control button TA, QA and indicator lamp are formed.
