Abstract

The utility model relates to a fixed concrete-building-block formation machine, which is used for building. The utility model comprises a lifting mould case, a mould emptier, and a vibrator. In order to lower the height of a block outlet flat layer, the mould emptier adopts a crank-link mechanism; a motor, a speed reducer, and a crank shaft are driven by a flexible belt so that the motor and the speed reducer can be arranged at the space of side surfaces of the crank shaft. The vibrator adopts a structure, four parallel shafts of the structure are engaged with each other, thereby, the active area of vibration is increased, and four blocks can be once formed in order to meet the requirement of stacking for building blocks.

Description

Fixed concrete block moulding machine

The utility model belongs to the building machinery field, is a kind of concrete block moulding machine.

Existing fixed formula concrete block forming has slip moulding box, mould emptier and a shake table mostly.Moulding box places on the shake table during work, adopts the mode of vibration moulding, makes the moulding box slippage by mould emptier then, finishes the demoulding.But existing most of make-up machines to go out piece flat bed height all higher, be 755mm as the piece flat bed height that goes out of homemade QTJ3-35 type make-up machine owing to be subjected to the structural limitations of mould emptier, its flat bed height can't reduce.Though adopt overhead mould emptier or hydraulic drive can reduce the flat bed height, the former causes the nose heave pin of make-up machine light, must strengthen frame, cost is improved; The latter need be equipped with hydraulic system, causes complex structure, costs an arm and a leg.The flat bed height is higher will to make the corresponding raising of the face height of each equipment on the production line, and this has not only increased the equipment rolled steel dosage, and has improved manufacturing expense.In addition, the vibrator exciting force of existing make-up machine and vibration effectively district are less, are difficult to four of one-shot formings, bring inconvenience to segment palletizing.

The purpose of this utility model provide a kind ofly go out that piece flat bed height is lower, vibration force is big, vibration effectively district's broad, plastic four fixed concrete block moulding machine once.

Solution of the present utility model is: the fixed concrete block moulding machine that is provided comprises lift moulding box, a mould emptier that can slide along column and the vibrator that links with shake table, and wherein moulding box is positioned at the shake table top.Said mould emptier is made up of the toggle that motor-driven decelerator and this decelerator drive, and wherein connecting rod and moulding box are hinged, between motor and the decelerator, all adopt flexibility to be with transmission between decelerator and the bent axle.Said vibrator by four side by side and pitch wheel eccentric shaft and drive motors form.Motor drives crankshaft rotating by decelerator during the demoulding, drives the moulding box ascending, descending by connecting rod again, finishes the demoulding.

Preferably adopt chain drive between decelerator and the bent axle,, also can under the situation that does not change the power transmission shaft position, change the chain gearratio simultaneously more conveniently, thereby satisfy the production requirement of different materials building block so that satisfy the requirement of low-speed big transmission.

Because be subjected to the restriction of make-up machine space structure, it is difficult adopting a more powerful motor.So above-mentioned vibrator preferably adopts two motors, they respectively drive a gear eccentric shaft by the flexibility band respectively.So both can make full use of the space and settle motor, make compact conformation, can strengthen oscillation power again.

The utility model is owing to adopted flexible band transmission and toggle; therefore motor and decelerator can be arranged in the space of toggle side easily; the length of crank and connecting rod also can shorten, thereby the whole height of mould emptier is dwindled, and has reduced piece flat bed height.Owing to adopted four mutual engagement type vibrators arranged side by side, the shake table width is strengthened, vibration effectively district increases, but not only four of one-shot formings, and the packing of each building block is even.In addition, the utility model has adopted the fully mechanical transmission, not only simple the but also reliable in action of structure.

Below in conjunction with accompanying drawing content of the present utility model is illustrated.

Fig. 1 is overall structure figure of the present utility model.

Fig. 2 is the structure chart of mould emptier.

Fig. 3 is that Fig. 2 is a vertical view.

Fig. 4 is the structure chart of vibrating mechanism.

As shown in Figure 1: this make-up machine by supporting plate feed mechanism 1, hopper and material-feeding mechanism 2, mould emptier 3, vibrator 4, the pressure head 5 that shakes, frame 6, roll platform 7 and electric cabinet 8 etc. and partly form.Two root posts 9 are arranged on the frame, and the supporting base 11 of moulding box 10 both sides can be along column 9 liftings.Raw material enters moulding box from hopper, and the pressure head 5 that shakes descends, and it is molded under vibration force and pressure effect raw material to be shaken, and mould emptier drives the moulding box rise then, and building block is deviate from.This make-up machine go out piece flat bed height less than 500mm.

The structure of mould emptier 3 such as Fig. 2, shown in Figure 3.It mainly is made up of decelerator 12 and toggle 13 two parts.12 of motor 14 and decelerators are used belt transmission, 15 employing chain 16 transmissions of decelerator 12 and bent axle, and the termination of connecting rod 17 is hinged on the moulding box supporting base 11.Drive supporting base 11 by crank 18 and connecting rod 17 when bent axle 15 rotates and slide, thereby drive the moulding box lifting, finish demoulding action along column 9.

The structure of vibrator 4 as shown in Figure 4.It is four eccentric shafts of adorning side by side in a casing 19 20, and each eccentric shaft is meshing with each other by the gear (not drawing among the figure) on the axle.Eccentric shaft rotation in the middle of two motors 21 drive respectively by belt 22.Because four eccentric shafts are positioned at same plane, thereby the horizontal component that produces cancels out each other, and only produces the vertical orientation vibration.Vibration force passes to shake table 23 through casing 19, passes to moulding box 10 through supporting plate 24 again.
