Technical field
The utility model is related to the weighing structures that a kind of ball-grinding machine grabs ball device.
Background technology
Ball mill equipment is current most extensive grinding mixing machinery, is widely used in ore dressing, building materials, electric power, cement and change
The industries such as work.Grinding process occupies important function in entire production technology, and output investment ratio is great, and energy consumption proportion is high, to product matter
Amount influences very big.The work of ball mill is to realize ball milling function by filling steel ball, and the quality of grinding efficiency is by the steel in mill
Ball is realized.After ball mill starts ore grinding work, the steel ball in mill will be worn, and total ball amount is reduced, in order to keep best
Ball amount and proportioning, it is necessary to continuous to supplement steel ball to maintain.Major part ball mill in China's is all artificial ball adding, ball adding side at present
Method is varied.The shortcomings that artificial ball adding one, is that ball adding amount is inaccurate, second is that ball adding is not in due course, while with the enlargement of ball mill
Development needs the amount for adding steel ball being also continuously increased, and frequency is also being accelerated, and manually ball adding is difficult to meet the need of ore grinding merely
It wants.
Ball mill needs timing, quantitative, in proportion the steel ball for supplementing various specifications when carrying out grinding operation, so that
Filling rate and the sphere diameter ratio of grinding machine are maintained in the range of requirement, to ensure the efficient operation of ball mill.For this purpose, developing
Often there is steel ball card, stifled and phenomena such as burn motor in a variety of intelligent ball adding devices, but practical application effect is all undesirable,
And it is difficult to realize add loading in mixture for various specifications steel ball.
Invention content
In order to solve deficiency in the prior art, the purpose of this utility model is to provide a kind of simple in structure, users
Just, accurate ball-grinding machine of weighing grabs the weighing structure of ball device.
To achieve the above object, the utility model uses following technical scheme：
A kind of ball-grinding machine grabs the weighing structure of ball device, including support arm, ball device, support arm is taken to be fixed on rack
On, the top of the support arm is equipped with pulley, and one end connection at the top for taking ball device and lifting rope, the middle part of lifting rope bypasses
It pulley and is supported on pulley, the other end of the lifting rope is connect with rack, and the support arm includes the first noumenon and second
Body, the bottom of the first noumenon are connect with the top of the second ontology, and pulley is arranged in the top of the first noumenon, the bottom of the second ontology
It is connect with rack, the junction of the first noumenon and the second ontology is equipped with weigh sensor block, the one end for sensor block of weighing and first
Body connects, and the other end for sensor block of weighing is connect with the second ontology.
The lifting rope is steel wire rope.
Pull pressure sensor is equipped in the sensor block of weighing, pull pressure sensor is connect with weighing circuit plate, the title
It is equipped with sensor signal conversion circuit and digital signal processing algorithm circuit in weight circuit board.
The first noumenon includes an interconnecting piece and the support portion that is obliquely installed.
Second ontology is obliquely installed second including an interconnecting piece, the first support portion and second the first support portion of support portion
Support portion is vertically arranged, and the inclined direction of the first support portion is identical as the inclined direction of the first noumenon support portion.
The utility model uses above technical scheme, the midfoot support of steel wire rope on pulley, take the gravity of ball device with
The force action of steel wire rope other end pulling force measures crawl steel on support arm by the sensor block of weighing being arranged on support arm
The weight of ball posts resistance strain plate in pull pressure sensor, then is equipped with bridge-type measuring circuit, is converted to electric signal output,
Simple in structure, measurement efficiency is high, takes ball device itself to have certain weight, that is, has given one pre- gravimetric value of sensor block of weighing,
So that steel ball to be measured is in the interlude of sensor block range of weighing, it is best using sensor center linear degree in the sensor block
It measures, eliminates null offset and stress is wriggled, improve the weighing precision for block of weighing.
Description of the drawings
The utility model is described in further details below in conjunction with the drawings and specific embodiments：
Fig. 1 is the schematic diagram for the weighing structure that a kind of ball-grinding machine of the utility model grabs ball device.
Specific implementation mode
As shown in Fig. 1, the utility model includes support arm 1, takes ball device 2, and support arm 1 is fixed on the rack, described
The top of support arm 1 is equipped with pulley 4, and the top for taking ball device 2 is connect with one end of lifting rope 3, and the middle part of lifting rope 3 is around cunning
Wheel 4 and is supported on pulley 4, and the other end of the lifting rope 3 is connect with rack, and the support arm 1 includes the first noumenon 11 and the
Two ontologies 12, the bottom of the first noumenon 11 are connect with the top of the second ontology 12, and pulley 4 is arranged at the top of the first noumenon 11,
The bottom of second ontology 12 is connect with rack, and the junction of the first noumenon 11 and the second ontology 12 is equipped with sensor block 5 of weighing, and weighs
One end of sensor block 5 is connect with the first noumenon 11, and the other end for sensor block 5 of weighing is connect with the second ontology 12.The lifting rope 3 is
Steel wire rope.Pull pressure sensor is equipped in the sensor block 5 of weighing, pull pressure sensor is connect with weighing circuit plate, the title
