Abstract

The utility model relates to a watch type measuring device for balk cargoes, which belongs to the field of bulk storehouse of slim materials. In the design, a frame (5) with a discharge door (6) is arranged under the discharge hopper (4) of a bulk material storage storehouse; the frame (5) is suspended on a lever (2) through a connecting rod (7); one end of the lever (2) and a weighing hopper (1) are fixedly connected into a whole; the other end of the lever (2) is connected with the surface of a contact rod (14) of a press spring weight watch (3). At the time of weighing, the material enters the weighing hopper (1) through a discharging door (16), causing the lever (2) to rotate around a shaft hinge (8). Thus the indicating needle of the weight watch (3) can be promoted to rotate to achieve the purpose of correct measuring.

Description

Watch type measuring apparatus for balk cargo

The utility model belongs to very thin material bulk warehouse field.

Measurement problem when cement and the discharging of other gossamer material storehouse in bulk is one of key of current development engineering in bulk.The more employing lever of China is weighed at present, promptly on weighing bucket, utilize lever principle to determine one quantitatively, reach this when a certain amount of in the weight of scale hooper then, lever one distal process so rises, this moment, the workman lost no time to close Dump gate, but because the flow that falls in the discharge funnel by storehouse in bulk is very big, often produced than mistake when the unexpected rise of lever is closed again, cause metering inaccurate, waste material.Also favourablely in addition claim that with electronic platform scale though can increase the accuracy of metering to a certain extent, its cost is more expensive, and easily polluted maintenance difficult under working environment in bulk by tiny dust.The utility model proposes and a kind ofly still utilize lever principle but can avoid above-mentioned shortcoming, and low cost, metering outfit easy to maintenance.

The utility model is to establish a framework that Dump gate is housed in the discharge funnel bottom of storage bin, and on framework the lifting lever, lever one end is connected with scale hooper, a compressed spring type weight table is established in other end top, therefore along with the material in the scale hooper increases, shown reading also progressively increases on the weight table, is convenient to the workman and operates and in time close the door and reach the accurate purpose of metering.

Details are as follows in conjunction with the accompanying drawings for the design:

Fig. 1 is a tabular form weigher synoptic diagram;

Fig. 2 is the A-A section of Fig. 1.

As shown in Figure 1, at the bottom of the discharge funnel (4) of a loose unpacked material storage bin welding square framework (5), framework (5) end opening with discharge funnel (4) suitable for reading is connected, and the end opening standard of framework (5) faces toward the suitable for reading of scale hooper (1).A Dump gate of being made by steel plate (6) is housed in the middle of the upper and lower opening, and Dump gate (6) can be the traditional pumping board formula or the structure of turnover plate type, and what the design proposed is a kind of revolving structure.As depicted in figs. 1 and 2, Dump gate (6) is a garden shape steel plate, the one end is connected with framework (5) with pivot pin (11), steel bar of other end welding stretches out the handgrip (12) of framework outer rim as Dump gate (6), pull palm (12) can make Dump gate (6) around pivot pin (11) thus rotation reaches the purpose of opening or closing discharge funnel (4) end opening.

As shown in Figure 1, at each affixed connecting rod (7) of the both sides of framework (5) (Fig. 1 is that side view can only be seen a side), the lower end of connecting rod (7) is lifting lever (2) and scale hooper (1) with axle hinge (8), the welding of the outer wall of one end of lever (2) and scale hooper (1) makes that both are affixed to be integral.The other end of lever (2) freely stretches out the scale hooper outer rim, because lever (2) and scale hooper (1) are affixed in aggregates and can cut with scissors (8) around axle and rotate, has formed the basic structure that a kind of lever is weighed in fact.At the free end of lever (2) balancing weight (10) that energy moves along lever is installed again, then can utilize the diverse location of balancing weight (10) on lever to make the scale hooper (1) of end dress material and lever (2) keep horizontality, that is to say in the moment on the both sides of axle hinge (8) equal.A stage clip weight of appropriate device table (3) is in the end of lever above on this level height, (the big I of stage clip weight table according to weigh select for use), the upright position of weight table (3) must make contact lever (14) most advanced and sophisticated of weight table (3) contact (or keep several millimeters space) just with the surface of lever (2), with the accuracy of assurance weighing.In addition, also be provided with tradition in the scale hooper bottom and use the manually-operated Dump gate (9) that has handle (13).

When using the design's weigher at first self-balanced upper rotary (10) make lever be in equilibrium state, so make the material in the storage bin discharge funnel (4) enter scale hooper (1) with opening Dump gate (6), this moment, effect lever (2) the drive scale hooper (1) owing to gravity rotated counterclockwise, the tail end of lever (2) upwards rises the contact lever (14) that makes table (3) and upwards compresses the pointer rotation that drives simultaneously in the weight table (3), along with material constantly flows into scale hooper, pointer also is rotated further, when pointer fast during near the weight scale that requires, operating personnel should turn down Dump gate (6) gradually, when pointer arrives desired scale, close Dump gate (6) fully, guaranteed the accuracy of weighing like this.

Claims

1, a kind of by scale hooper (1), the loose unpacked material tabular form weigher that lever (2) weight table (3) is formed, feature of the present utility model is a quadra of end opening stationary installation (5) of the discharge funnel (4) of storage bin, be provided with one in the framework (5) and unload door (6), each affixed connecting rod (7) of the both sides of framework, the lower end of connecting rod (7) is provided with the scale hooper (1) of Dump gate (9) with axle hinge (8) connection lever (2) and bottom, the fixing welding of the outer wall of above-mentioned lever (2) one ends and scale hooper (1), the other end freely stretches out the outer rim of scale hooper, and a balancing weight (10) that can move along lever is set thereon, and a compressed spring type weight table (3) is set and becomes the loose unpacked material tabular form weigher that a lever is weighed in the terminal top position of lever (2).

2, by the described weigher of claim 1, it is characterized by Dump gate (6) and be the garden shape iron plate that to rotate around pivot pin (11), pivot pin (11) is fixed in iron plate on the framework (5), and the other end of iron plate is equipped with the handgrip (12) that stretches out framework (5) outer rim.
