Abstract

The utility model relates to a valve device for filling balk cargo, comprising cambered shutters fixed on the lower funnel of a stockhouse and an electric push rod controlled by a microcomputer. The shutter are divided into an optical shutter and a slow shutter, the optical shutter and the slow shutter interlap and are respectively provided with a big discharge hole and a small discharge hole, the two shutters combine with each other forming a big feed inlet or a middle feed inlet or a small feed inlet driven by the electric push rod, finally the feed inlet is completely closed, then the utility model can accurately fill the balk cargo, the labour intensity of the workers is reduced, and the workers are free from the dust harm and can keep health. The utility model can form an automated packaging pipelined matched with other seaming and packaging devices, rope scissoring devices and running row devices.

Description

Valve device for filling balk cargo

The utility model relates to the valve arrangement that the fragmentary material of can that a kind of separation of material uses is used.

The fragmentary material of current can does not still have the mechanical filling apparatus of accurate weighing, is example with can grain promptly, adopts artificial can mostly, the platform balance weighing, and labour intensity is big, and dust is many, and it is healthy to influence the workman; Some is by the direct can of funnel under the feed bin, but valve under the general funnel is simple in structure, is difficult for the accurately dirty material quantity of control, so be difficult to reach the purpose of quantitative filling.

The purpose of this utility model is that a kind of can valve arrangement that fragmentary material is used will be provided, and this device is the can material on request, makes weighing accurate, and is time saving and energy saving during operation, raises labour productivity, and protects the workman healthy effectively.

The purpose of this utility model is achieved in that valve arrangement that the fragmentary material of this can uses is by being fixed under the feed bin two circular-arc valve on the funnel and being made of micro-processor controlled electric pushrod, wherein the below is a shutter, leave the little rectangle gap that to adjust size in shutter one side, be slow door thereon, the middle part of slow door is provided with discharging opening, both sides at discharging opening, be respectively equipped with rectangle and T-shaped baffle plate, when filling with substance is under system controlled by computer, shutter is opened, material flows in a large number, promotes slow door then, and bell mouth is blocked half, continue charging, then shutter close, the gap can material by shutter only is when reaching specified quantity at last, promote slow goalkeeper's gap sealing, can finishes.

The utility model has following advantage:

1) divide large, medium and small three kinds of valve feedings, under microcomputer and relevant device cooperation, make can material quantity accurately and reliably, thereby can alleviate labor strength, increase work efficiency, be not subjected to dust harzard, useful workman is healthy.

2) the utility model and corresponding seam bag are cut rope and running gear and are matched, and can realize mechanization, the automation of can material, good development prospect.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the utility model master TV structure scheme drawing.

Fig. 2 is the main scheme drawing of looking of slow door.

Fig. 3 is slow door schematic top plan view.

Fig. 4 is that the shutter master looks scheme drawing.

Fig. 5 is the shutter schematic top plan view.

Fig. 6 is the regulating plate plan sketch.

Describe detailed structure of the present utility model and service condition thereof in detail below in conjunction with accompanying drawing.

With reference to Fig. 1～6, the utility model is by being fixed on the arc valve on 1 time funnel of feed bin with anchor 19 and being made of micro-processor controlled electric pushrod, one side of shutter 5 has a little gap 11 of rectangle, and gap is connected with the flow control board 12 of a band vee 6 for 11 times; Regulating plate 12 is provided with two slotted holes 18, screw 17 passes slotted hole 18 regulating plate 12 is fixed on the shutter 5, slow door 7 is positioned at the top of shutter 5, the middle part of slow door 7, be provided with discharging opening 15, one side of discharging opening 15 is provided with rectangle baffle plate 13, and opposite side is provided with T-shaped baffle plate 14, and the protruding tongue 16 on the baffle plate 14 is corresponding with gap 11; Shutter 5 is connected with electric pushrod 4 on being fixed on support 2, slow door 5 is connected with electric pushrod 4 on being fixed on support 2, and travel switch 3 and travel switch 8 are located at a side of electric pushrod 4 and 9 respectively, so that with microcomputer, the switching of control valve and slack.

During use, under system controlled by computer, drive shutter 5 by electric pushrod 4 earlier, make shutter 5 around the rotation of strand nail 19 anticlockwise directions, when the AB position forwards to beyond the B point, travel switch 3 touches the shutter spiral arm and stops operating, at this moment valve is all opened, be the big feeding stage, this section is after the period, slow door 7 is under the drive of push rod 9, rotate around anchor 19 clockwise directions, when its C point reached the B point, travel switch 8 touched slow door spiral arm and slack, and at this moment rectangle baffle plate 13 blocks half with valve, work the effect of damming, be the middle feeding stage, in the time of will reaching quantitative requirement, shutter 5 is under push rod 4 drives, around anchor 19 right-hand revolutions, set back, material can only be from shutter 5 one sides, and part is conditioned in the rectangle gap 11 that plate 12 blocks and flows out downwards, all the other bell mouths are all blocked, for the little feeding stage, when reaching quantitative criterion, push rod 9 promotes slow door 7 and does the anticlockwise direction rotation around anchor 19 rapidly, set back, be that the C point is got back to the C point from the B point again, the protruding tongue 16 on the at this moment slow door 7 just in time blocks rectangle gap 11, and feeding procedure promptly is all over.

When material has speed because of difference flow velocitys such as particle diameters, can utilize the slotted hole 18 on the regulating plate 12, move its position on shutter 5, change the size of little spout, make weighing accurately and reliably.

Claims

1, the valve arrangement used of the fragmentary material of a kind of can by being fixed on two circular-arc valve on 1 time funnel of feed bin and being made of micro-processor controlled electric pushrod, is characterized in that:
