Description

Plumb-bob Material Level Meter

The utility model relates to a kind of device that is used for measuring the material level of powdery, graininess and lump material feed bin, relates to a kind of Plumb-bob Material Level Meter specifically, belongs to the bin-level surveying instrument.

At present; along with development and national economy; greatly enriching of material; feed bin is also more and more; the device or the instrument that are used to measure bin-level are also more and more exquisite; precision; accuracy requirement is more and more higher; existingly be used for measuring powdery; the weight dropper charge level indicator of graininess and blocks of solid material bin-level, its ultimate principle all are to drive weight decline measuring distance with wire rope, and weight returns after running into charge level weightlessness; but all being wire rope, the structure of general weight dropper charge level indicator at random twists on the very thin dish; above being entangled in mutually layer by layer, whether weight can't judge to the top, motionless and generate heat to the commentaries on classics of top motor until weight; monitoring the intensification signal just shuts down; this irregular winding method, consequently having caused wire rope is not that to fail to lay down be exactly can not draw up, and often causes and buries hammer; fall hammer; can't normally use; especially in high pressure dust storehouse, a large amount of dust suck in the instrument, easily cause the damage of level-sensing device; need often to repair, safeguard very difficulty.

The purpose of this utility model provides a kind of rational in infrastructure, can make the wire rope proper alignment, the Plumb-bob Material Level Meter of monitoring bin-level that can be effectively correct, and the phenomenon to stop burying hammer, to fall hammer overcomes the deficiencies in the prior art.

The purpose of this utility model is to realize like this, it mainly by: to top switch (1), tongue tube (2), magnet steel (3), spool gear axle (4), casing (5), pinion wheel (6), gear wheel (7), lead screw shaft (8), worm gear (9), shaft coupling (10), motor (11), worm screw (12), wire rope (14), reel (15), cover (16), weight parts such as (25) are formed, it is characterized in that: lead screw shaft (8) is installed in the casing (5), lead screw shaft (8) is provided with screw (13) and reel (15) is installed, wire rope (14) one ends are connected with reel (15) left end, the other end is around the home on reel (15), through upper block (19), elastic wheel (30), behind the lower tumbler (21), be connected with weight (25) by lead ring (24); Worm screw (12) is connected with motor (11) by shaft coupling (10), gearing mesh on spool gear axle (4) and reel (15) left end, the left end head of spool gear axle (4) is equipped with magnet steel (3), spool gear axle (4) right-hand member is by pinion wheel (6) and gear wheel (7) engagement, worm gear (9) is installed on the worm screw (12), worm gear (9) and lead screw shaft (8) engagement, lead screw shaft (8) and gear wheel (7) engagement, be installed on the casing (5) to top switch (1), and it is mutually close with reel (15) left end, tongue tube (2) is installed on the casing (5), and close with magnet steel (3); Its feature also is also to be equipped with in the casing (5) swing arm (17), switch (18), upper block (19), stage clip (20), lower tumbler (21) on earth, and funnel (22) is installed in the bottom of casing (5); Its feature is that also base (29) is connected with cover (16), in the cover (16) casing (5) is installed, cast iron bracket (23) upper end is connected with base (29), cast iron bracket (23) lower end is connected with bearing (27), bearing (27) is connected with feed bin (26), and gland bonnet (28) is installed in the lower end of cast iron bracket (23).

Compared with prior art it is rational in infrastructure for the utility model, can effectively react the upper-lower position of weight in feed bin, measurement is accurate, precision is high, can prevent that the high pressure dust from sucking, the phenomenon of can effectively stop to bury hammer, falling hammer also can guarantee the measurement of carrying out bin-level reliably and with long-term under the situation of environment very severe.
