Abstract

The utility model discloses a bucket gate opening or closing device for block forming machines. A bucket gate is composed of a baffle plate and a side plate, wherein, the side plate of the bucket gate is hinged on side walls of a bucket by a pin shaft; the front side of the side plate of the bucket gate is provided with a U-shaped slot; the side surface of a skip which is positioned below the bucket is provided with a roller, and the bucket gate can be driven to move by the roller. Compared with existing bucket gate opening or closing devices for block forming machines, the utility model does not need additional power sources. The utility model has the advantages of simple structure and easy fabrication. The utility model is suitable for machines of making concrete.

Description

A kind of block machine sluice gate opening and closing device

The utility model relates to a kind of block machine sluice gate opening and closing device.

The unlatching of used block machine sluice gate and close following three kinds of modes are generally arranged.First kind drives sluice gate by hydraulic jack and opens, closes, handle electric button control hydraulic pressure commutation and cut down the switching oil circuit, make the forward and reverse motion of oil cylinder to open and close hopper, second kind is power with compressed air, by air compressor machine, cylinder, air distribution system and electrical system are controlled the unlatching of sluice gate and are closed, and the third is to adopt electric pushrod to promote sluice gate to open and close; Above-mentioned three kinds of mode complex structures also need be established power source in addition, and cost is also higher

The purpose of this utility model is for overcoming above-mentioned deficiency, and designs a kind of U-lag of establishing on sluice gate, establishes the block machine sluice gate opening and closing device of roller on the truck; Simple in structure and saved power source.

The utility model content, the side plate of block machine sluice gate opening and closing device sluice gate is hinged on the sidewall of hopper, the front of sluice gate side plate be provided with can be hinged with roller U-lag; The side that is positioned at the truck below the hopper is provided with the roller that promotes the sluice gate motion.

The utility model advantage, block machine sluice gate opening and closing device relies on the reciprocating motion of truck to drive sluice gate by the roller on the truck and realizes opening and closing, do not need to establish power source and transmission mechanism in addition, and is simple in structure, saves the energy, makes easily.

Description of drawings:

Fig. 1 is the utility model front view (signal)

Below in conjunction with the preferred embodiment of description of drawings the utility model, this block machine sluice gate opening and closing device is the improvement to used sluice gate mechanism, sluice gate is made up of the side plate of baffle plate and both sides, baffle plate 6 is a circular arc, side plate 2 is fan-shaped, and side plate is provided with U-lag 8, and side plate is hinged on the sidewall of hopper 4 through bearing pin 3, be positioned on the and arranged on left and right sides wall of the truck 5 below the hopper and be separately installed with roll wheel assembly, roll wheel assembly is made up of roller 1, fixed axis, packing ring and nut; Roller can rotate flexibly with respect to fixed axis, when truck advances, because the roller on the truck side is positioned in the U-lag of sluice gate side plate, driving sluice gate rotates around bearing pin, behind the discharging opening 7 of the flapper closure hopper of sluice gate, roller breaks away from the U-lag notch and continues to be advanced to anteposition, i.e. the cloth position; After cloth finished, truck returned, and the roller on the truck side is entered in the U-lag by the U-lag notch, drove sluice gate and rotated backward around bearing pin, opened the discharging opening of hopper, feeded to truck; Truck also arrives back position stop motion simultaneously; At this moment roller rests in the U-lag, after filling material in the truck, starts truck again toward the anteposition motion, begins the next feed cycle, and the friction of the batching of the weight of the location dependence sluice gate when sluice gate is closed and the inboard of sluice gate baffle plate and hopper door realizes; Location when sluice gate is opened is that truck stops to move after truck arrives the position, back, inserts in the roller restriction sluice gate displacement on the truck in the U-lag of sluice gate side plate.

Claims

1, a kind of block machine sluice gate opening and closing device, it is characterized in that: the side plate of sluice gate is hinged on the sidewall of hopper, the front of sluice gate side plate be provided with can be hinged with roller U-lag; The side that is positioned at the truck below the hopper is provided with the roller that promotes the sluice gate motion.
