Abstract
The utility model discloses a spiral electronic scale which comprises a shell body connected to a supporting frame, wherein a spiral shaft driven by a power device is arranged in the shell body, and spiral blades are arranged on the spiral shaft. The bottom of the front end of the supporting frame is provided with a lever supporting frame, and the upper portion of the rear end of the shell body is provided with a weighing sensor hook. The front end of the shell body is provided with a feeding funnel with an upward opening, the lower portion of the rear end of the shell body is provided with a discharging pipe, and a distributor capable of distributing materials is arranged on the feeding funnel. Through the arrangement of the distributor at a spiral feeding inlet, the defect of uneven material distribution is overcome, impact on the spiral shaft when the materials fall down is reduced, measuring accuracy of the spiral electronic scale is guaranteed, and feeding amount is effectively controlled.
Description
Technical field
The utility model relates to a kind of spiral electronic scales.
Background technology
There is the inhomogeneous shortcoming of blanking in existing spiral electronic scales inlet point place, and the impulsive force to screw shaft when material falls is big influential to the precision of spiral electronic scales, thereby causes the weighing of spiral electronic scales inaccurate, and then can not accurately control inlet amount.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of spiral electronic scales to the impulsive force of screw shaft when reducing material and falling.
For solving the problems of the technologies described above, the utility model comprises the housing that is connected on the bracing frame, be provided with the screw shaft that is driven by engine installation in the housing, helicallobe is installed on the screw shaft, the front bottom end of support frame as described above is equipped with the lever bracing frame, the upper rear end of housing is provided with the LOAD CELLS hook, and the front end of housing is equipped with opening loading hopper, rear end lower up and is provided with discharge nozzle, and it is characterized in that being equipped with on the described loading hopper can be with the tripper of material diversion.
Described tripper is fixed on the inwall of loading hopper along the axial setting of screw shaft and its both ends.。
Described tripper has the dip plane of extending to both sides from its middle part and dip plane and screw shaft and be arranged in parallel.
The width of described tripper and the diameter of screw shaft adapt.
Described lever bracing frame comprises that base and symmetry are connected ear seat on the base, and being rotationally connected by pivot shaft on the ear seat is useful on the bearing of carrying bracing frame.
The two ends of described screw shaft are being respectively equipped with for the packing seal with the screw shaft radial seal with the housing junction.
Described engine installation is buncher.
After adopting said structure, at the LOAD CELLS hook LOAD CELLS is installed, during spiral electronic scales convey materials, LOAD CELLS converts the weight of material on the weighing section to voltage signal and sends into the signal transmitting device, the signal transmitting device carries out becoming digital signal after the preliminary calculation process to signal, communication interface by standard sends controlled adjuster to, controlled adjuster is handled and is shown, draw the current flow that passes through the material of spiral electronic scales, the controlled adjuster outgoing current gives variable-frequency governor with the adjusting motor speed, thereby reaches the purpose of dosing.The utility model has improved the inhomogeneous shortcoming of blanking by at the screw feed en-trance place tripper being set, and to the impulsive force of screw shaft, has guaranteed the survey precision of spiral electronic scales, thereby has effectively controlled inlet amount when having reduced the material whereabouts.This spiral electronic scales is rational in infrastructure, stable and reliable operation, and good airproof performance does not have the transport efficiency of leakage height, and is easy to maintenance.
