Abstract
The invention relates to an agricultural labor-saving sieve. The agricultural labor-saving sieve comprises a sieve body, a sieve frame and a power system, wherein the sieve frame supports the sieve body; by using the power system, the sieve body can move back and forth on the sieve frame in a translational manner; the sieve frame is provided with two parallel guiding shafts; sliding sleeves which can be in sliding fit connection with the guiding shafts are arranged on two sides of the sieve body; the power system comprises a rotating shaft; the rotating shaft is supported on a mounting support via a bearing block; one end of the rotating shaft is connected with a rotating wheel; the rotating wheel is connected with the sieve body via a two-connecting-rod mechanism; a reset spring is connected between the rotating shaft and the mounting support; the middle of the rotating shaft is fixedly connected with a shaft sleeve; and the shaft sleeve is connected with a pedal device. According to the agricultural labor-saving sieve, the rotating wheel can be driven to rotate by using the pedal device, kinetic energy can be converted into energy for driving the sieve to move horizontally through the two-connecting-rod mechanism, and the sieve can move back and forth along a shaft of a track, so that sieving operation is realized. The agricultural labor-saving sieve is time-saving and labor-saving, and is high in controllability.
Description
Technical field
The present invention relates to farm equipment, relate in particular to a kind of agricultural laborsaving sifter.
Background technology
At present, the mechanization popularity rate of agricultural production is very high, but for mountain area and remote districts, many agricultural productions still depend on manual work.Screening is operated in agricultural production very important, and it is one important procedure to grain decontamination and sorting, but traditional method for sieving is with dustpan, impurity to be winnowed with a dustpan out, or manually screens out with sieve, wastes time and energy, and efficiency is low.
Summary of the invention
In order to address the above problem, the present invention proposes a kind of agricultural laborsaving sifter, this sifter 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.
This invention is achieved through the following technical solutions: a kind of agricultural laborsaving sifter, 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 of described rotating shaft connects runner, and described runner 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 runner are hinged.Be rotating shaft when static balance state, the end of runner is upward.
Described pedal is rotatably connected with connecting rod, pedal can be in the plane perpendicular to connecting rod 360 rotations, the convenient direction that regulates pedal, is convenient for people to two pin and replaces operations, lessens fatigue, and increases work efficiency.
Described screen frame (unit) bottom is provided with receiver, can splendid attire material under screening.
The invention has the beneficial effects as follows: a kind of agricultural laborsaving sifter, this sifter 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.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Accompanying drawing 1 is a kind of structural representation of agricultural laborsaving sifter.
In figure, 1. screen frame (unit), the 2. axis of guide, 3. sieve nest, 4. sliding sleeve, 5. two linkages, 6. runner, 7. mounting bracket, 8. rotating shaft, 9. bearing block, 10. axle sleeve, 11. pedals, 12. back-moving springs, 13. connecting rods.
The specific embodiment
In the accompanying drawings, a kind of agricultural laborsaving sifter, comprises sieve nest 3, supports the screen frame (unit) 1 of sieve nest 3, also comprises and can make sieve nest 3 on screen frame (unit) 1, make the dynamical system of reciprocal translational motion; Described screen frame (unit) 1 is provided with the parallel axis of guide of twice 2; The both sides of described sieve nest 3 be provided with can with the sliding sleeve 4 of the axis of guide 2 sliding connections; Described moving system comprises a rotating shaft 8, and described rotating shaft 8 is supported on a mounting bracket 7 by bearing block 9; One end of described rotating shaft 8 connects runner 6, and described runner 6 is connected with sieve nest 3 by two linkages 5; Between described rotating shaft 8 and mounting bracket 7, be connected back-moving spring 12; The middle part of described rotating shaft 8 is fixedly connected with an axle sleeve 10, on described axle sleeve 10, connects a foot pedal apparatus.
One end of described two linkages 5 is articulated with one end of sliding sleeve 4, and the other end and runner 6 are hinged.Be rotating shaft 8 when static balance state, the end of runner 6 is upward.
Described foot pedal apparatus comprises a connecting rod 13, and the top of described connecting rod 13 and axle sleeve 10 are hinged, bottom connecting pin pedal 11.
Described pedal 11 is rotatably connected with connecting rod 13, pedal 11 can be in the plane perpendicular to connecting rod 13 360 rotations, the convenient direction that regulates pedal 11, is convenient for people to two pin and replaces operations, lessens fatigue, and increases work efficiency.
Described screen frame (unit) 1 bottom is provided with receiver, can splendid attire material under screening.
During use, trample pedal downwards, rotating shaft 8 is rotated, thereby drive two linkages 5 to pull sieve nest 3 along the axis of guide 2 to a side translation, unclamp pedal 11, under the effect of back-moving spring 12, rotating shaft 8 revolutions, thereby make two linkage 5 homings, promote sieve nest 3 to opposite side translation, with this, move in circles and can realize screening operation.
