Abstract

The utility model relates to an automatic-measure device for unloading and arch breaking, belonging to the field of measure devices for unloading the slim materials. The utility model uses the mechanical arch breaking and spiral delivery to cause the materials to enter a measure hopper uniformly. The materials can be accurately measured by the mode of lever mechanical weighing for two times. The correctness of each measure can be guaranteed by using the method of automatic control of a contact switch. The precision can reach 1-0.5%. A measure mechanism is arranged in a sealed box which is mechanical transmission weighting, and thus the utility model is suitable for the places with poor working environment, such as the bulk cement, etc.

Description

Auto-measure device for break arch unloading apparatus

The design belongs to fine material discharging metering outfit field.

The transportation in bulk of raft fine material is in recent years used more and more widely, especially in China in order to save timber, require sack cement to change bulk cement into after, more cause the attention of the attention of each side, particularly cement industry and civil engineering industry.Under such background, multiple discharging metering outfit appears on the market, and the said equipment is to utilize the heavy or expression of first degree lever of computer meter weigh (being that weighing lever claims the top formula) mostly.But in practicality, find,, can't in cement industry, stablize use,, influence the precision of electronic scale, even very fast complete failure because too tiny cement dust can be invaded body though electronic scale has the high characteristics of precision.One time lever scale utilizes lever directly to weigh, and equipment is simple, and cost is lower, but its precision is relatively poor, and movement response is slow, neither solve the good scheme of bulk cement metering.Therefore the design's purpose is to propose a kind of cheaply at above-mentioned shortcoming, has the mechanical metering outfit of certain precision.

Another purpose of the design provides the broken arch of a kind of handle, and discharging and metering are linked to be the broken arch discharging self-measuring device of an integral body.This device not only is suitable for bulk cement, and is applicable to for example grain of other various very thin materials, engineering in bulk such as breeze.

The design's characteristics are to utilize machinery to break up arch, the spiral conveying tube feeding, and twice lever type mechanical weighed and reached even discharging, helical feed, correct metering, the purpose of control automatically.

Details are as follows in conjunction with the accompanying drawings in the design's detailed description:

The general assembly (GA) synoptic diagram of Fig. 1, broken arch discharger self-measuring device;

Fig. 2, weighing balance treasure elevational schematic view;

A-A sectional view among Fig. 3, Fig. 2;

Fig. 4, weighing balance measuring device side view.

As shown in the figure, the design forms package unit by basin discharge funnel (1), spiral conveyer (2), meter (6) and weighing hopper (9).Even for discharging, percussion arch-breaking device (4) is housed in discharge funnel (1), Arch-Breaking Device (4) is driven by the bent axle (16) in the spiral conveyer of motor (15) driving, can guarantee that like this discharging and defeated material are even.On the discharge port (5) of spiral conveyer (2) flange (7) is housed, this flange is connected with flange (8) on the meter (6).Meter (6) below has four hooks (10) to be connected with weighing hopper (9), and there is a Dump gate (11) this weighing hopper (9) below.The outward appearance of meter (6) is a square seal box, the mark post case (13) of dress metering mark post (601) in one end of seal box protrudes one, mark post case (13) has one can prevent that dust from entering the hermatic door of meter inside (14), and sealing door (14) is by the surface of two hinges (12) peace table in mark post case (13).Open hermatic door (14) and can determine the size of metering at mark post (601).

One fulcrum (602) is arranged in the mark post case, mark post (601) is installed on fulcrum (602) and goes up and can rotate around (602), one counterbalance weight (603) and suspension hook (606) are arranged on the mark post on the fulcrum left side, and above-mentioned suspension hook (606) links to each other with long pass guide rod (611) is terminal.A contact switch (615) that is connected with drive motor (15) is equipped be carved with weight scale on the mark post on fulcrum the right, and in vernier (604) and (605) that a definite metering size is respectively arranged up and down of mark post, the low order end of mark post.Suspension hook (606) hooks a long pass guide rod (611) and leads (611) by long pass and fuses with the conduction mechanism of weighing.Above-mentioned conduction mechanism comprises as shown in Figure 3 and Figure 4, four jiaos a knife rest (609) is arranged respectively at meter (6) inner bottom part, there is a blade (610) to be set up on the support (608) on the knife rest (609), also be provided with a hook (10) on above-mentioned four knife rests (609) and hang the weighing hopper (9) that has Dump gate (11), each is connected corresponding two knife rests (609) with (614) by a connecting rod (607), wherein (607) are connected with long pass guide rod (611), another root connecting rod (614) is connected with short pass guide rod (612), and between long pass guide rod (611) and the short pass guide rod (612) with two short connecting rods (613) link together (Fig. 4).Therefore the weight of weighing hopper (9) can be through hook (10) four knife rests (609), and connecting rod (607) and (614) and short pass guide rod (612) and long pass guide rod (611) reach the hook (606) of mark post (601), reach the purpose of weighing.

At first open hermatic door (14) in use, determining with two verniers that alleged weight is closed then seals up a door, start motor (15), make the running of Arch-Breaking Device (4) and spiral conveyer (2), the material in the storage storehouse discharge funnel (1) constantly enters weighing hopper (9) by the outlet (5) of spiral conveyer (2).Weight in the weighing hopper (9) is passed to the hook (606) on metering mark post (601) left side through conduction mechanism, reach institute when weighing to weight, metering mark post (601) rotates counterclockwise up to contact switch (615) and contacts, motor (15) quits work, discharging stops, the weight of meter bucket (9) interior material is determined alleged weight just, opens the discharging thing door (11) of weighing hopper then, and discharging also continues automatic gauge discharging next time.Above-mentioned discharge gate (11) can be various traditional plate-turning doors, and various gate.

The scheme system that the design proposes comprises brokenly complete outfits such as arch, conveying, automatic gauge, discharging, but also can use separately, for example in this complete equipment, save spiral conveyer, directly material is imported weighing hopper (9) by discharge funnel (1), at this moment the necessary material that guarantees that discharge funnel unloaded is even and logistics capacity is less, otherwise can influence measuring accuracy even damage meter.The selected arch breaking apparatus of the design is the percussion arch-breaking device, uses other arch broken equipment but also do not get rid of, oscillatory type Arch-Breaking Device etc. for example, but can increase propulsion system like this, expense increases.

The design's broken arch discharger self-measuring device is reasonable in design, and cost is lower, and is easy to use, can be used in the discharging metering engineering of various loose unpacked materials.The design's precision can reach 1.0-0.5% according to the requirement of material.
