Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific examples, which should not be construed as limiting the invention.

Example 1

As shown in fig. 1-4, a grain screening machine comprises a bottom plate 1, two square upright posts 12 are fixedly connected to the upper side of the bottom plate 1, two upright posts 12 are rotatably connected to rotating rods 2, a rectangular screening box 3 is fixedly connected between the two rotating rods 2, a flow guide opening 33 is arranged on the upper side of the screening box 3, and grains can be conveniently guided into the screening box 3 through the flow guide opening 33. All be equipped with the spout between 3 inner wall both sides of screening case, the first screening board 31 of sliding connection between two spouts, fixed connection second screening board 32 between 3 inner walls of screening case, second screening board 32 pastes at first screening board 31 upside, all is equipped with the same screening hole 4 in multirow aperture on first screening board 31 and the

second screening board

32, and 1 upside of bottom plate is equipped with into

magazine

8, and 8 upsides in feeding magazine are equipped with the opening. The feed box 8 is located directly below the screening box 3, and grains screened from the screening box 3 can enter the feed box 8 from the opening. When the screening holes 4 on the first screening plate 31 and the second screening plate 32 are completely overlapped, the grain size screened is the largest; the grain size of the screened grains is gradually reduced as the screening holes 4 on the first screening plate 31 and the second screening plate 32 are gradually staggered; when the screening holes 4 of the first and

second screening plates

31, 32 are completely staggered, the underside of the screening box 3 is in a closed state and screening cannot be performed. One side of the first screening plate 31 is fixedly connected with a pull rod 322, and the pull rod 322 is provided with an adjusting device 5 for adjusting the grain size range screened by the first screening plate 31 and the second screening plate 32. Adjusting device 5 includes connecting rod 51, and connecting rod 51 fixed connection is in pull rod 322 downside, and connecting rod 51 lower extreme fixed connection is dull and stereotyped 52, is equipped with the guiding hole on the dull and stereotyped 52, sliding connection dead lever 53 in the guiding hole, and dead lever 53 lower extreme fixed connection baffle 54 cup joints first spring 55 on the dead lever 53, and first spring 55 fixed connection is between baffle 54 and dull and stereotyped 52. In the free state, the first spring 55 pulls the shutter 54 so that the fixing lever 53 moves upward. The adjusting plate 56 is fixedly connected to the lower side of the screening box 3, a plurality of adjusting holes 57 are formed in the lower side of the adjusting plate 56, the adjusting holes 57 in the adjusting plate 56 correspond to the overlapping ranges of the screening holes 4 in the first screening plate 31 and the second screening plate 32 respectively, and the adjusting holes 57 are arranged corresponding to the fixing rods 53. After the fixing rod 53 is pulled downwards, the pulling rod 322 is pulled to make the first sieving plate 31 move in the chute, so that the fixing rod 53 on the flat plate 52 is displaced. By inserting the fixing rods 53 into the different adjustment holes 57, the degree of coincidence of the screening holes 4 of the first and

second screening plates

31 and 32 can be adjusted, thereby adjusting the particle size of the screened grain particles.

One side of the upright 12 is provided with a power device 6 for controlling the sieving box 3 to horizontally shake. Power device 6 includes backup pad 61, backup pad 61 fixed connection in pole setting 12 one side, backup pad 61 one side fixed connection motor 62, and the motor 62 main shaft passes backup pad 61 fixed connection cam 63, and dwang 2 passes pole setting 12 one end fixed connection push pedal 64, and cam 63 and push pedal 64 butt set up cup joint second spring 65 on the dwang 2, and second spring 65 fixed connection is between push pedal 64 and pole setting 12. In the free state, the second spring 65 is not stressed. The other rotating rod 2 penetrates through one end of the upright 12 and is fixedly connected with a limit plate 66. Starter motor 62 drives cam 63 and rotates, and cam 63 rotates the in-process, and cam 63's convex surface can constantly take place the contact with push pedal 64 for push pedal 64 promotes dwang 2 and slides in pole setting 12, thereby drives screening case 3 along dwang 2 direction reciprocating motion between two risers 12, and then makes the grain granule in the screening case 3 be difficult for piling up at the incasement, improves the screening speed to grain granule. The stop plate 66 prevents the swivelling levers 2 from slipping out of the uprights 12. Equal fixed connection push rod 7 in relative one side of two pole settings 12, every push rod 7 all passes screening case 3 and stretches into the incasement, and the equal fixed connection rubber slab 71 of one end that every push rod 7 stretched into the incasement, the relative both sides of screening case 3 inner wall all are equipped with rotation groove 312, all rotate through pivot 311 in every rotation groove 312 and connect swing board 72, all are equipped with the torsional spring on every pivot 311. In the free state, the torsion spring is not stressed, and both the swing plates 72 are arranged obliquely downward. Each push rod 7 is provided in correspondence with the swing plate 72. In the process that the screening box 3 moves between the two vertical plates 12 in a reciprocating mode, the rubber plate 71 on the push rod 7 is constantly in contact with the adjacent oscillating plate 72, so that the oscillating plate 72 oscillates upwards, grain particles in the screening box 3 are thrown back and forth by the oscillating plate 72, the grain particles are distributed in the screening box 3 more uniformly, and the screening speed of the grain particles is further improved; when the push rod 7 is far away from the swinging plate, the swinging plate can restore the original position under the action of the torsion spring. The rubber plate 71 plays a role of buffering and damping between the push rod 7 and the swing plate 72, and prevents the push rod 7 and the swing plate 72 from directly contacting to damage both sides.

During the use, with cereal from the leading-in screening case 3 of guiding opening 33 in, adjust first screening board 31 and second screening board 32 screening cereal particle size through adjusting device 5, then under power device 6's cooperation for cereal granule sieves in the feed box 8 of below from the screening case 3.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
