Description
Technical field
The present invention relates to a kind of self-locking scale hooper mechanism, mainly for the occasion will sought quickness in large gravitational material and weighing speed.
Background technology
The scale hooper structure of prior art is simple, in the occasion will sought quickness for large gravitational material and weighing speed, in order to prevent bin gate softened, general is mostly prevent material from washing weighing sluice gate open by the structure of increase balancing weight, there is the situation of seepage, its complex structure, its scale hooper one-piece construction adds counterweight block structure, LOAD CELLS load capacity in weighing process can be caused large, weighing precision is low, and weigh the folding speed of sluice gate and the stability of overall weighing mechanism and be not easy to control, can request for utilization be met.
Summary of the invention
The object of the invention is the deficiency in order to make up prior art, providing a kind of self-locking scale hooper mechanism.
The present invention is achieved through the following technical solutions:
A kind of self-locking scale hooper mechanism, include bucket body, it is characterized in that: the both sides of described bucket body are respectively equipped with scale hooper support, the bearing of described scale hooper stent outer is provided with bearing sensor, described scale hooper support is rotatablely equipped with respectively L shape rotary arm, the bottom of described L shape rotary arm is fixedly connected with the sluice gate below it, described sluice gate coordinates with bucket body discharging opening, be connected with the end, upper end of the rotary arm below it in the middle part of described sluice gate lower surface, described rotary arm includes pull bar, one end of described pull bar is connected with the ear that is connected and fixed be provided with in the middle part of sluice gate lower surface, the other end is provided with cross bar, the two ends of described cross bar are respectively equipped with connecting lever, the middle part of described connecting lever is rotatably installed in the bottom of scale hooper support respectively, connecting link is provided with between the end, rear end of connecting lever, the middle part of described connecting link is connected with motor-driven motor pivot arm end, described motor pivot arm is arranged on the edge of the flap of motor output shaft end, the rearward end of described connecting lever is separately installed with extension spring, the upper end of described extension spring is arranged on the scale hooper support with its respective side respectively.
Principle of work is as follows: adopt scale hooper to close the door and rely on the automatic mode crossing dead point locking of the screen resilience of spring, avoid sluice gate when conventional scale hooper weighs large gravitational material easily softened, and cylinder form Kai Dou mechanism weighing unit has the phenomenon of impact, ensure that and weigh the folding speed of sluice gate and the stability of overall weighing mechanism, improve measuring accuracy.When adopting spring to drive scale hooper door to close, utilize pivot arm and is connected pivoted arm and completes self-locking, prevent material from washing weighing sluice gate open, seepage occurs, self-locking during by weighing sluice gate closedown, prevents weighing sluice gate from being strutted by material, for the weighing and bagging of material.
Advantage of the present invention is:
Reasonable in design of the present invention, adopts scale hooper to close the door and relies on the automatic mode crossing dead point locking of the screen resilience of spring, ensure that and weigh the folding speed of sluice gate and the stability of overall weighing mechanism, improve measuring accuracy, avoid the situation that seepage occurs simultaneously.

Embodiment
See accompanying drawing, a kind of self-locking scale hooper mechanism, include bucket body 1, the both sides of bucket body 1 are respectively equipped with scale hooper support 2, bearing outside scale hooper support 2 is provided with bearing sensor 3, scale hooper support 2 is rotatablely equipped with respectively L shape rotary arm 4, the bottom of L shape rotary arm 4 is fixedly connected with the sluice gate 5 below it, sluice gate 5 coordinates with the discharging opening of bucket body 1, be connected with the end, upper end of the rotary arm 6 below it in the middle part of sluice gate 5 lower surface, rotary arm 6 includes pull bar 7, one end of pull bar 7 is connected with the ear 8 that is connected and fixed be provided with in the middle part of sluice gate lower surface, the other end is provided with cross bar 9, the two ends of cross bar 9 are respectively equipped with connecting lever 10, the middle part of connecting lever 10 is rotatably installed in the bottom of scale hooper support 2 respectively, connecting link 11 is provided with between the end, rear end of connecting lever 10, motor pivot arm 13 end that middle part and the motor 12 of connecting link 11 drive is connected, motor pivot arm 13 is arranged on the edge of the flap of motor 12 output shaft end, the rearward end of connecting lever 10 is separately installed with extension spring 14, the upper end of extension spring 14 is arranged on the scale hooper support 2 with its respective side respectively.
Stage 1: when starting to weigh, rotary arm is in self-locking position, in bucket body, material gravity component is by the rotary arm point of rotation, the arm of force is zero, cannot strut sluice gate, and sensor detects scale hooper weight, when reaching order nominal magnitude, the connecting link of motor Received signal strength rotating down pressing scale hooper, destroys self-locking mechanism, realizes opening bucket.
In the stage 2: while motor pivot arm to lowest point continues to rotate up, rotary arm comes back to initial self-locking position under the acting force of extension spring, starts weighing next time.
