Detailed Description

A rice screening machine is shown in figure 1 and comprises a box body 1, wherein a feeding hole 2 is formed in the upper portion of the box body 1, a feeding pipeline 3 is communicated with the feeding hole 2, the upper end of a coarse screen 4 is hinged to the inner wall of the box body 1, the coarse screen 4 is obliquely arranged, an oblique fine screen 5 is arranged below the lower end of the coarse screen 4, the oblique direction of the fine screen 5 is opposite to that of the coarse screen 4, a first outlet 6, a second outlet 7 and a third outlet 8 are respectively formed in the box body 1, the first outlet 6 is located on the lower end side portion of the coarse screen 4, the second outlet 7 is located on the lower end side portion of the fine screen 5, the third outlet 8 is located at the bottom of the box body 1, a connecting plate 9 is arranged on the lower end side portion of the coarse screen 4, the connecting plate 9 extends out of the first outlet 6, a vertical electric push rod 10 is installed on the outer wall of the box body 1, the movable end of the electric push rod, slide rail 11 is located coarse screen 4's lower extreme top, and slidable mounting slider 12 on slide rail 11, the one end of articulated sieve 13 on the slider 12, and the other end of sieve 13 is articulated with coarse screen 4, and the width of sieve 13 is the same with 1 inner wall interval of box, and sieve 13 is the same with coarse screen 4's sieve mesh diameter, and coarse screen 4's sieve mesh diameter is greater than fine screen 5's sieve mesh diameter. This kind of structure can make the corn screening time, get into box 1 and fall on coarse screen 4 by charge-in pipeline 3, the corn accomplishes preliminary screening along coarse screen 4 gliding in-process, after the corn reachs coarse screen 4 bottom, by the interception of sieve 13, the corn is along coarse screen 4 gliding in-process, the expansion end that can control electric putter 10 is flexible repeatedly, thereby make connecting plate 9 and coarse screen 4 rise and fall repeatedly, make the corn on the coarse screen 4 accomplish vibrations screening, continue screening on fine screen 5 by the corn that falls on the coarse screen 4, accomplish further screening. After the rice screening in the box body 1 is completed, the electric push rod 10 can be closed, and then one end of the sieve plate 13 is opened, or the slide block 12 is separated from the slide rail 11, so that the sieve plate 13 is opened, and the left materials staying on the coarse screen 4 leave the box body 1, so that the next round of screening is performed. This kind of structure can control the screening of corn long and can make the vibrations screening of corn, makes the corn can be through abundant screening, improves the screening effect of corn.

The side wall of the box body 1 is provided with an L-shaped material guide hole 14, one end of the material guide hole 14 is communicated with the first outlet 6, the other end of the material guide hole 14 is communicated with the outside of the box body 1, the lower part of the coarse screen 4 is provided with a baffle 15, and the baffle 15 is positioned in the material guide hole 14. This arrangement enables the baffle 15 to block material from exiting the tank 1 through the first outlet 6 below the coarse screen 4 when the coarse screen 4 is raised. Because the rise and fall of the coarse screen 4 move along the arc direction, the baffle 15 has a certain radian along with the rise and fall of the coarse screen 4, and the width of the material guide hole 14 is larger than that of the baffle 15, so that the baffle 15 can be prevented from colliding with the box body 1 when rising and falling. The paddy falling into the guide holes 14 can be separated from the guide holes 14, so that blockage is avoided.

The feed inlets 2 and the feed pipes 3 are multiple, the upper parts of every two feed pipes 3 are communicated with the material distributing pipe 17, and the upper parts of the material distributing pipes 17 are communicated with the main pipeline 16. This kind of structure can make corn fall on coarse screen 4 by many places feed inlet 2 to make corn distribute evenly on coarse screen 4, improve the screening effect.

The feeding pipeline 3 and the material distributing pipe 17 are obliquely arranged, an oblique adjusting plate 18 is arranged at the upper part of the feeding pipeline 3 with the same inclination direction corresponding to the material distributing pipe 17, and the adjusting plate 18 is communicated with the upper part of the other feeding pipeline 3 and has the same inclination direction. This kind of structure can adjust the volume of the corn that gets into different feed tube 3, further makes the corn evenly drop on coarse screen 4.

Technical scheme of the utility model not be restricted to the utility model the within range of embodiment. The technical contents not described in detail in the present invention are all known techniques.
