Abstract
The utility model provides a concrete mixing device with a precise measurement ,comprising a mixing tank on which is provided with a sandstone measuring hopper, a water measuring hopper, and a cement measuring hopper respectively, wherein the sandstone measuring hopper is arranged with a feeding hopper which is further provided with a drive controlling the two openness (large and small) of the hopper gate; the water measuring hopper is connected with two sets of low-lift water pumps through a pipeline and located under the outlet of a spiral conveyor which is in a linkage with a frequency-changing electric machine. The utility model enjoys advantages of an accurate measurement of raw materials and therefore may be applied to concrete processing.
Description
Technical field
The utility model relates to a kind of construction machine, refers in particular to a kind of concrete central mix plant with accurate measurement of the concrete batch plant that is used for the concrete stirring.
Background technology
At present, in the measuring raw materials device of traditional concrete batch plant, the metering system of its sand, building stones all adopts a metering sluice gate, open sluice gate by unidirectional cylinder and carry out the blanking metering, for improving equipment yield, the aperture of metering sluice gate is bigger, and is very big to the impulse force of weighing hopper, had a strong impact on measuring accuracy (fines measurement deviation such as sand is 3～8%, and the rubble measurement deviation is 2～6%); The higher suction pump pumping of lift is all adopted in its water supply, thus also very big to the impulse force of water weighing hopper, had a strong impact on measuring accuracy (measuring accuracy of water is 2～3%).And a rotating speed is all adopted in the metering of cement, flyash, and cause because of motor stops the cement of carrying in the needed time more, cause the cement-weighting deviation very big.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of a kind of concrete central mix plant with accurate measurement of easy to use, accurate measurement is provided.
The purpose of this utility model is achieved in that a kind of concrete central mix plant with accurate measurement, comprise a mixing bowl, on a mixing bowl, be provided with sandstone weighing hopper, water weighing hopper and cement-weighting bucket, be provided with loading hopper on the sandstone weighing hopper, wherein: described loading hopper is provided with the drive unit of large and small two apertures of control sluice gate; The water weighing hopper is communicated with two low lift suction pumps by pipeline; The cement-weighting bucket is positioned at the delivery outlet bottom of screw conveyer, screw conveyer and variable-frequency motor interlock.
Drive unit described in the concrete central mix plant of above-mentioned band accurate measurement is two-way cylinder.
Drive unit described in the concrete central mix plant of above-mentioned band accurate measurement is unidirectional cylinder and forms near switch combination.
After the utility model adopts said structure, compared with prior art have following advantage:
(1) realizes two apertures of reinforced sluice gate by two-way cylinder or near switch and unidirectional cylinder, realize thick, the smart secondary measurement of sand, building stones by the aperture size; Thick metering can improve equipment yield, and smart metering has improved the measuring accuracy of raw material.
(2) suction pump of low lift is adopted in the supply of water, has significantly reduced the impulse force of water to weighing hopper, has improved measuring accuracy.
(3) can make screw conveyer produce two rotating speeds by variable-frequency motor, realize thick, the thin secondary measurement of the charging of cement, improve measuring accuracy.
(4) measuring accuracy that can improve raw material reaches 1%.
