Description

one

The invention relates to the field of construction, namely to construction finishing devices for the production of plastering.

A device for receiving, mixing and supplying a plaster solution is known, consisting of a frame on which a receiving hopper with a vibrator is mounted, a paddle mixer whose capacity communicates with the receiving hopper by means of a swivel of their bottoms, mortar pump / block for additives, solution pipes and a trolley moving the device. The receiving jj bin is made with the possibility of vertical movement by means of a ram to supply the solution to the mixer tank l.

However, this device does not provide a supply of a homogeneous composition to the workplace due to the separation of the solution in the receiving bin.

It is also known a device for receiving, mixing and supplying a plaster solution, including a supporting frame, a receiving bin, a rotor mixer with buckets and a shaft with a drive, installed in a receiving bin, also Q

forehead, vibrating screen, feed tank, mortar pump and mortar 2.

The specified device to the technical essence and the achieved result is closest to the offer.

In a known device, the mixing of the solution in the receiving bin is carried out only in the area of the bucket of the rotary agitator, which does not ensure the development of the entire volume of plaster in the receiving bunker and leads to its heterogeneity.

The purpose of the invention is to improve the uniformity of the plaster and improve the operating conditions.

This is achieved by the fact that in the device for receiving, mixing and supplying plaster, including a supporting frame, a receiving hopper, a mixer with a bucket rotor, a driven shaft, a chute, a vibrating screen, a supply tank, a mortar pump and solution lines, the mixer is equipped with a return mechanism the movement of the rotor, made in the form of a hollow slide, fastened to the rotor and mounted on the drive shaft with the possibility of longitudinal re; yet. the propeller is kinematically connected to the drive shaft and a nut mounted on the propeller and interacting with the slider by means of levers and a clutch mounted on a slider. Such an embodiment of the device simultaneously rotates the agitator rotor and moves it inside the receiving hopper, which allows the whole mass to be mixed plaster mortar, located in the bunker, and clean it when installing the rotor in the desired position.

FIG. 1 shows a device for receiving, moving and supplying a plaster solution, a longitudinal section in FIG. 2 is the same in plan; FIG. 3 shows the mechanism for reciprocating movement of the stirrer rotor (section A-A in FIG. 1); FIG. 4 is the same, section BB,

The device contains a receiving hopper 1 with a mixer with a bucket rotor 2 placed in it, a chute 3 for feeding the KOVSHOVM solution with a rotor “from the receiving hopper to the vibrating screen 4, installed above the supply tank 5 and a mortar pump with solution lines (not shown). The mixer has a drive 7-for reversing rotation of the rotor 2 and actuating the reciprocating movement mechanism consisting of a hollow slider 8 fixed to the rotor and mounted on the drive shaft 9 / spindle screw 10 arranged parallel to the drive shaft, the nut 11 mounted on the lead screw with viH 12 and 13. levers fixed on it - gears 14 fixed on the lead screw, coupling 15 mounted on the slide and sprocket 16 that connect the kinematically drive shaft with the agitator drive and the propeller . The levers of the nut are brought into engagement with the slide of the slide using wedge-shaped rails 17 and 18. All mechanisms of the device are mounted on a supporting frame 19.

The device works as follows.

The receiving bin 1 is loaded with the solution. The actuator 7 is turned on in the direction of rotation of the hub of the rotor 2 to stir the solution. The nut 11 begins to move along the spindle screw 10 in the direction of the location of the receiving bin 1 (in the drawing along the arrow c). Moreover, the lever

12, running down from the inclined surface of the rail 18, rises up and the lever

13, the lowering enters into the annular groove of the M1 15 and moves the latter along the drive shaft 9 together with the slider 8 and the rotor 2, / whose buckets the solution is mixed.

along the entire receiving hopper 1. When the lever 12 rushes onto the inclined rjo-top of the rail 17, the nut 11 is turned around its axis. In this case, the lever 13, lifting up to the upper position, j, disengages from the col-. the ninth groove of the coupling 15 and the longitudinal movement of the bucket rotor 2 is stopped 11}. When the rotation of the bucket rotor 2 is reversed, it returns to its original position.

O In this case, the solution captured by the buckets of the rotor 2 is re-mixed and at the same time moves from the edge of the receiving bin 1 to the solution feed zone by the bucket rotor 2 through

5, the chute 3 and the vibrating screen 4 into the supply tank 5 and further with the mortar pump 6 are transported via the solution line to the workplace. When the movement of the bucket rotor 2 to the original

The Q position is the order of the interaction, the chugs 12 and 13 with the coupling 15, and the rails 17 and 18 are repeated in the opposite direction.

Due to the reciprocating movement of the stirrer's bucket rotor inside the receiving hopper, mixing of the plaster is ensured, which improves its uniformity, and also improves the operating conditions of the device due to the convenience of cleaning the receiving hopper when the bucket rotor is installed in the desired position.
