The surface of the assembling plate 3 is fixedly provided with a push-pull mechanism 7, and the push-pull mechanism 7 is movably connected with the box body 5.
The push-pull mechanism 7 comprises a motor 701, a shell of the motor 701 and the assembly plate 3 are fixedly arranged, a crankshaft of the motor 701 is fixedly connected with a rotary disc 702, a pin 703 is inserted into the surface of the rotary disc 702, the pin 703 is arranged at an eccentric position of the top surface of the rotary disc 702, the pin 703 and the top surface of the rotary disc 702 are vertically arranged, a transmission arm 704 is movably sleeved on the surface of the pin 703, a connecting shaft 705 is inserted into the front end of the transmission arm 704, and the connecting shaft 705 is movably connected with the back of the box body 5. The turntable 702, together with the pin 703, the connecting shaft 705, the driving arm 704, the cartridge 5, and the guide rail 4, forms a crank link structure, and when the turntable 702 rotates, the driving arm 704 is pulled and drives the cartridge 5 to perform a reciprocating linear motion in a forward-backward direction along the guide rail 4.
The top of the guide rail 4 is provided with a guide mechanism 8, and the bottom of the guide mechanism 8 and the top surface of the sieve plate 6 are arranged in a sliding fit manner. Through setting up guiding mechanism 8, to reciprocal action of straight line around cooperation box body 5 and sieve 6, make the cereal on sieve 6 surface produce the removal action along outer eight characters guide board 804 and interior eight characters guide board 805 side surface, increased cereal about sieve 6 surface to the removal stroke, the tiling and the expansion of the cereal of being convenient for, the make full use of in sieve 6 hole of being convenient for promotes screening operating efficiency.
The guide mechanism 8 comprises a bridge-shaped frame 801, and the left side and the right side of the bridge-shaped frame 801 are fixedly connected with the guide rail 4.
The bottom surface of the middle part of the bridge-shaped frame 801 is in threaded connection with a connecting screw rod 802, the bottom of the connecting screw rod 802 is fixedly connected with a connecting rod 803, the connecting rod 803 is in an I-shaped structure, an outer splayed guide plate 804 is fixedly arranged at the front part of the connecting rod 803, and an inner splayed guide plate 805 is fixedly arranged at the rear part of the connecting rod 803.
The bottom surfaces of the outer splayed guide plate 804 and the inner splayed guide plate 805 are connected with the top surface of the sieve plate 6 in a sliding fit manner.
The opening size of the back side of the outer splayed guide plate 804 is smaller than the opening size of the front side of the inner splayed guide plate 805. When the grains move backward along the sieve plate 6, the grains can gather toward the middle along the front of the inner splayed guide plate 805, and the front of the gathered grains opens toward the back of the outer splayed guide plate 804.
The middle part of the front side of the outer splayed guide plate 804 is a discharge gap, an entrance gap is formed between the left side and the right side of the rear part of the outer splayed guide plate 804 and the front side of the inner splayed guide plate 805 respectively, and the opening size of the back side of the inner splayed guide plate 805 is smaller than that of the back side of the outer splayed guide plate 804. The middle of the back side of the inner splayed guide plate 805 is a stacking gap. Through setting up guiding mechanism 8, utilize outer eight characters guide board 804 and the forward-backward setting of interior eight characters guide board 805, 6 front portions of sieve put in behind the cereal, under dragging of driving arm 704, sieve 6 is forward, backward be a cycle forward again, make cereal can be at first concentrated to the middle part along the front of interior eight characters guide board 805, then concentrate to the middle part along the back of outer eight characters guide board 804, make the bran that can't pass through at last and large granule can concentrate at 6 central line positions of sieve, avoid large granule materials such as bran to spread on 6 surfaces of sieve, hinder to disturb the fine material and pass through sieve 6, the collection operation of large granule material and impurity of also being convenient for.
This practical theory of operation: this rice chaff device for agricultural grain processing when sieve 6 extends forward, drops into cereal to sieve 6 front portion, and cereal follows sieve 6 backshifts for cereal pastes the front that leans on inside and outside splayed guide board 804 and the front that interior splayed guide board 805 and moves, makes cereal have the central line position of sieve 6 to move separately left and right side. Drag the application of force around following the sieve 6, the actual movement track of cereal for sieve 6 has increased cereal at the removal stroke on 6 surfaces of sieve for the oblique motion of the slope of the right side left by the middle part for cereal for the contact chance of cereal and sieve mesh becomes many, and the fine material falls to 1 inboards of the casing of bucket form through 6 holes of sieve more easily, realizes the ejection of compact action of whereabouts.
Due to the forward movement of the sieve plate 6, the grains move backwards relative to the guide mechanism 8, pass through the inlet gap and gather in the stacking gap after passing through the front surface of the inner splayed guide plate 805.
Afterwards, the sieve plate 6 moves backwards along the guide rail 4 under the pulling of the transmission arm 704, at the moment, grains move forwards relative to the guide mechanism 8 along the sieve plate 6, the materials in the stacking gap abut against the back of the outward splayed guide plate 804 and gradually gather together towards the central line position of the sieve plate 6, in the moving process of the grains relative to the sieve plate 6, fine materials fall through the pores of the sieve plate 6, large-particle materials such as bran and the like which do not pass through the sieve plate 6 and impurities are gradually gathered together at the discharge gap position of the central line of the sieve plate 6 by the outward splayed guide plate 804 and the inward splayed guide plate 805, and the collection operation of the impurities is facilitated.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
