Abstract
Disclosed is a seat type single-belt variable-frequency speed regulation scale. Aiming to solve the technical problems of difficult leveling, low measuring accuracy and the short service life of a hanging type single-belt scale, the seat type single-belt variable-frequency speed regulation scale adopts the following technical scheme: the speed regulation scale comprises a conveying belt, a shaping hopper arranged above the conveying belt, a weighing mechanism and a drive mechanism. The key points of the speed regulation scale is in that the weighing mechanism comprises an underframe arranged below the conveying belt, the underframe is provided with supports equipped with rolling balls and a sensor, and the underframe and a groove-shaped frame on the conveying belt form the weighing structure by means of the supports and the sensor. The seat type single-belt variable-frequency speed regulation scale has the following technical effects: the seat type single-belt scale can perform leveling simply and conveniently and has high stability, the problem that support points are stressed uniformly so that a lateral twisting force is generated on the tension sensor and thus measuring accuracy is influenced is prevented, the measuring accuracy is improved, and the service life of the single-belt scale is prolonged.
Description
Technical field
The utility model belongs to batching metering technical field, relates to a kind of frequency control scale, is particularly widely used in a kind of seat formula single belt frequency control scale in the batching metering of building materials, chemical industry, metallurgy, coal, feed.
Background technology
Suspension type single-skin drum belt scale is widely used in industrial and mining enterprises being used for material to weigh, and realizes the gage work to batching.Suspension type single-skin drum belt scale utilizes lever principle to design, belt conveyor is take swivel bearing as fulcrum, utilize the stretching of pulling force sensor to measure the weight of material, but in long-term use procedure, it is found that this single-skin drum belt scale is not easy leveling, and because belt conveyor rotates around swivel bearing repeatedly, belt conveyor wearing and tearing are very fast, serviceable life is shorter, the friction force producing between belt conveyor and swivel bearing can affect the accuracy that single-skin drum belt scale is measured, and fulcrum is stressed not for the moment, pulling force sensor produces side direction torsion, also can affect the accuracy that single-skin drum belt scale is measured.
Summary of the invention
The purpose of this utility model is to be not easy leveling in order to solve suspension type single-skin drum belt scale, the accuracy of measuring is low, the technical matters that serviceable life is shorter, in order to address these problems, we have designed a kind of formula single belt frequency control scale, adopt the weighing mechanism of pellet type, good stability, simple and convenient when leveling, and avoid belt conveyor repeatedly to rotate caused wearing and tearing around swivel bearing, avoided, due to stressed the differing of fulcrum, pulling force sensor is produced to side direction torsion simultaneously, thereby affect the problem of accuracy of measurement, improve the accuracy of measuring, extend the serviceable life of single-skin drum belt scale.
The utility model for the concrete technical scheme that realizes goal of the invention and adopt is: a kind of seat formula single belt frequency control scale, comprise belt conveyor, be arranged on shaping hopper, weighing mechanism and the driving mechanism of belt conveyor top, key is: described weighing mechanism comprises the underframe that is arranged on belt conveyor below, underframe is provided with support and the sensor with spin, and underframe forms weighing structure by the grooved framework on support and sensor and belt conveyor.
The beneficial effects of the utility model are: underframe forms weighing structure by the grooved framework on support and sensor and belt conveyor, when on-the-spot use, can regulate the leveling of grooved framework carrying out height with the support that regulates screw thread according to actual conditions, make each fulcrum and each sensor stressed evenly, improve the accuracy of measuring, extended the serviceable life of single-skin drum belt scale.The material that falls at underframe is held middle or both sides setting
1~
2individual sensor, feed end both sides are provided with two supports, under the prerequisite that guarantees accuracy of measurement, have saved cost.Support coordinates the side direction torsion that belt conveyor is produced to become sensor power vertically downward with the rotation of base by footstock, realize the leveling of single-skin drum belt scale by the adjusting screw thread on base, and the leveling of single-skin drum belt scale is more prone to.The rubber sheet gasket arranging on footstock can reduce the degree of wear of footstock, makes leveling more accurate, has extended the serviceable life of support.
