Abstract
The utility model relates to a pedal type labor-saving sieving device which comprises a sieve, a sieve frame for supporting the sieve and a dynamical system for causing the sieve to have a reciprocating translational motion on the sieve frame, wherein two parallel guide shafts are arranged on the sieve frame; slide sleeves in siding fit connection with the guide shafts are arranged on the two sides of the sieve; the dynamical system comprises a rotating shaft; the rotating shaft is supported on a mounting bracket by a bearing base; a crank is connected with one end of the rotating shaft; the crank is connected with the sieve through a two-connecting-rod mechanism; a reset spring is connected between the rotating shaft and the mounting bracket; a shaft sleeve is fixedly connected with the middle part of the rotating shaft; and a pedal device is connected with the shaft sleeve. The pedal type labor-saving sieving device can drive a rotating wheel to rotate through the pedal device, can convert kinetic energy into horizontal moving energy through the two-connecting-rod mechanism, can cause the sieve to move back and forth along the rail shaft, can realize sieving operation, is time-saving and labor-saving, and has excellent controllability.
Description
Technical field
The utility model relates to use for laboratory screening plant, relates in particular to a kind of foot-operated laborsaving screening plant.
Background technology
In experiment, often adopt screen cloth screening sand, traditional screening plant is simple in structure, needs people's manual operations, consumption power is time-consuming, although and electric sieve extension set is laborsaving saves time, but in the more or less situation of husky amount, be difficult to control, and power consumption is large.
Utility model content
In order to address the above problem, the utility model proposes a kind of foot-operated laborsaving screening plant, this device can drive runner to rotate by foot pedal apparatus, and the energy that kinetic transformation is become to move horizontally by two linkages, sieve can be moved around along axis of an orbit, realize screening operation, time saving and energy saving, controllability is good.
The utility model is achieved through the following technical solutions: a kind of foot-operated laborsaving screening plant, comprise sieve nest, and support the screen frame (unit) of sieve nest, also comprise the dynamical system that can make sieve nest do reciprocal translational motion on screen frame (unit); Described screen frame (unit) is provided with the parallel axis of guide of twice; The both sides of described sieve nest be provided with can with the sliding sleeve of axis of guide sliding connection; Described moving system comprises a rotating shaft, described rotating shaft by bearing block support on a mounting bracket; One end connecting crank of described rotating shaft, described crank is connected with sieve nest by two linkages; Between described rotating shaft and mounting bracket, be connected back-moving spring; The middle part of described rotating shaft is fixedly connected with an axle sleeve, connects a foot pedal apparatus on described axle sleeve.
One end of described two linkages is articulated with one end of sliding sleeve, and the other end and crank are hinged.Be rotating shaft when static balance state, the end of crank is upward.
Described foot pedal apparatus comprises a connecting rod, and top and the axle sleeve of described connecting rod are hinged, bottom connecting pin pedal.
Described screen frame (unit) bottom is provided with receiver, can splendid attire material under screening.
The beneficial effects of the utility model are: a kind of foot-operated laborsaving screening plant, this device can drive runner to rotate by foot pedal apparatus, and the energy that kinetic transformation is become to move horizontally by two linkages, sieve can be moved around along axis of an orbit, realize screening operation, time saving and energy saving, controllability is good.
