Abstract

The utility model discloses a concrete mixing device which consists of a chassis, a rail, an intermediate hopper, a hopper, a hopper lifting steel rope, a mixing drum, a pulley and a pulley shaft; the device moves a connecting bolt and a regulating spacer originally installed on a discharge door rail pulley shaft of the hopper to the lower rail pulley shaft of the hopper by enlarging the distance between the lower rail pulley and the discharge door rail pulley of the hopper, and integrates the hopper discharge door rail pulley shaft and the hopper discharge door through welding, so that the discharge door spacing change is small, and the discharge door rail pulley and the rail do not deform. The lower part of the intermediate hopper is provided with a vibration motor, so that the residual material of the intermediate hopper is greatly reduced, so as to reduce the failure rate of the mixing device, prolong the equipment service life, reduce the labor intensity of the workers and improve the production efficiency.

Description

A kind of concrete central mix plant

Technical field

This uses novel involved engineering machinery field, specially refers to concrete central mix plant.

Background technology

The elevating hopper of present existing agitating device generally all has 3 groups of 6 pulleys, and a kind of is 4 pulleys in the track, outer 2 pulleys of track; Another kind is 6 pulleys in the track.Existing agitating device uses the elevating hopper that 6 pulleys are arranged in the track mostly, the door of this kind elevating hopper has an axle to play the adjustment doors gap bottom, it is by being bolted on the band iron, there is the adjustment pad centre, the problem of this kind regulating shaft is: (1) bolt is subjected to dynamic loading big, and is yielding, come off; (2) bolt hole weakens the intensity of axle, adds that cantilever design is oversize, makes shaft distortion easily, thereby loses the corrective action of hopper door gap; (3) the door-hinge positional structure is unreasonable, makes door-hinge stressed big during work.No matter moreover how the design angle of middle hopper to change, after cement and water are in contact with it simultaneously, be easy to adhere to, will expect mouthful to block and form a large amount of cement blocks, unload under the material in the big hopper is difficult.The big frame of existing agitating device and the connected mode of track are that big frame and track directly flush, and its defective is the outwards distortion easily of the inner stressed back of track, directly causes crack between a door and its frame to become big, outwards derails up to pulley.

Technology contents

It is little that the novel purpose of this use is to provide a kind of Dump gate gap to change, Dump gate track pulley spindle and not redeformation of track, the concrete central mix plant that middle hopper material residual quantity greatly reduces.

For achieving the above object, the novel concrete technical scheme of this use is:

Concrete central mix plant by underframe, track, middle hopper, hopper, hopper lifting steel cable and mixing drum are formed is equipped with two groups of track pulleys in the bottom of hopper.Foot is equipped with two hopper discharge door track pulleys, and connect with pulley spindle, two ends at pulley spindle are welded with the pulley spindle fixed supported slab respectively, and the other end of pulley spindle fixed supported slab is welded on the casing of hopper discharge door, make discharging track pulley, pulley spindle and hopper discharge door become as a whole.Hopper lower railway pulley is housed above Dump gate track pulley, and connect with pulley spindle, connecting bolt is housed on pulley spindle, connecting bolt connects pulley spindle, and with regulate pad and hopper lower railway pulley spindle fixedly angle steel be connected as a single entity the size of regulating the gap of hopper discharge door by the adjusting pad.

A vibrating motor is housed in the bottom of middle hopper.Underframe and track are welding, and whole rail is clamped.

Good effect of the present utility model is: by strengthening the distance of hopper lower railway pulley and hopper discharge door track pulley room, with the former connecting bolt that is contained in hopper discharge door track pulley spindle, regulate pad, move on on the hopper lower railway pulley spindle, and use welding that hopper lower railway pulley spindle is become as a whole with the hopper discharge door, it is little that its Dump gate gap is changed, Dump gate track pulley spindle and not redeformation of track, the residual quantity of middle hopper greatly reduces, so can reduce the fault of agitating device, reduce hand labor intensity, prolong equipment life, improve market efficiency.

The specific embodiment:

Further describe the novel specific embodiment of this use below in conjunction with accompanying drawing:

After in hopper (5), feeding, connect power supply, hopper (5) is in upwards operation of the traction lower edge of boom hoist cable (11) track (2), the rotation counterclockwise of two track pulleys (6) constraint hoppers (5) above the hopper (5), so being close to track (2) upper limbs, pulley (6) rolls, two hopper lower railway pulleys (7) constraint hopper below the hopper (5) moves along orbital plane, and orbital plane becomes certain inclination angle with horizontal plane, roll so hopper lower railway pulley (7) is close to track (2) lower limb.Two hopper discharge door track pulleys (8) on the hopper discharge door (9) constraint bin gate is opened around bin gate (10) clockwise direction of shipping and reselling on another market, so being close to track (2) upper limbs, hopper discharge door track pulley (8) rolls, after hopper (5) rises to the discharging height, hopper lower railway pulley (7) enters discharging turnout (4), hopper discharge door (9) is opened gradually, the beginning discharging, enter mixing drum (12) through middle hopper (13), open the vibrating motor (14) of middle hopper (13) bottom simultaneously, the material in the middle hopper (13) is entered in the mixing drum (12) smoothly.Decline hopper (5), hopper lower railway pulley (7) is returned in the track (2) by discharging turnout (4), and hopper discharge door (9) is closed automatically, thereby finishes the loading and unloading process.

Claims
