Detailed Description

In order to make the technical means, creation features, achievement purposes and actions of the present invention clearer and easier to understand, the following technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 4, the embodiment of the present invention provides an anti-clogging rice screening device, which comprises a body 1, a feeding assembly, a first screen plate 3 and a second screen plate 4; the first sieve plate 3 and the second sieve plate 4 are sequentially arranged in the body 1 in an inclined manner from top to bottom, and vibration assemblies are further arranged on the first sieve plate 3 and the second sieve plate 4; the feeding assembly comprises a feeding box 2, a round table 21, a rotating ring 24 and a plurality of rotating blocks 25, a feeding port is arranged above the feeding box 2, a cylinder fixedly connected with the top wall of the feeding box 2 is arranged at the center of the round table 21, a baffle ring 22 is fixedly arranged between the round table 21 and the feeding box 2, a feeding port 23 is arranged on the baffle ring 22, the rotating ring 24 is sleeved on the cylinder and can rotate along the axis of the round table 21, and the rotating blocks 25 are arranged at the lower part of the rotating ring 24 along the radial direction of the round table 21.

A first waste outlet 11 is formed in one end, located at the lower end of the first sieve plate 3, of the body 1, a discharge port 12 is formed in one end, located at the lower end of the second sieve plate 4, of the body 1, sieve holes of the first sieve plate 3 are larger than sieve holes of the second sieve plate 4, impurities, larger than full grains of rice, cannot pass through the sieve holes of the first sieve plate 3 when passing through the first sieve plate 3, and therefore large impurities are discharged through the first waste outlet 11, sieve holes of the second sieve plate 4 are smaller than the full grains of rice, when the rice falls onto the second sieve plate 4 from the first sieve plate 3, high-quality rice can be screened by the second sieve plate 4 and then collected through the discharge port 12, and other fine impurities fall to the bottom of the body 1 through the sieve holes of the second sieve plate 4; the first sieve plate 3 and the second sieve plate 4 are also provided with vibrating components, and the first sieve plate 3 and the second sieve plate 4 are vibrated by the vibrating components, so that rice on the first sieve plate 3 and the second sieve plate 4 is better screened, and the screening efficiency is improved; the feeding component is used for uniformly feeding; a motor is provided to control the rotation of the rotating ring 24; the feeding box 2 is provided with a feeding hole which is not arranged above the feeding hole 23, so that the rice is prevented from directly falling from the feeding hole and entering the body 1 through the feeding hole 23; when rice falls onto the circular truncated cone 21 from the feeding hole, the rice falls between the two adjacent rotating blocks 25 and is blocked by the baffle ring 22 and cannot fall into the body 1 downwards, the rice rotates to the position provided with the feeding hole 23 along with the rotation of the rotating ring 24, and the rice enters the body 1 through the feeding hole 23, so that uniform feeding is realized; in order to enable the rice to fall into the body 1 completely, the upper surface of the circular table 21 is inclined towards the edge along the radial direction, and has a certain inclination, so that the rice automatically falls into the feeding port 23.

Realize carrying out even pay-off to the rice through the pay-off subassembly and filter in body 1, it is too much to have avoided disposable pay-off, lead to first sieve 3, second sieve 4 can not carry out abundant screening to the rice, impurity can not in time be filtered and come out, the card is at first sieve 3, in the sieve mesh of second sieve 4, make first sieve 3, second sieve 4 blocks up, and simultaneously, the vibration subassembly has also been set up, to first sieve 3, second sieve 4 vibrates, sieve mesh on having avoided first sieve 3 and the second sieve 4 is stopped up, the emergence of jam has further been reduced, and simultaneously, also make the efficiency of screening obtain improving.

As shown in fig. 1 and 4, the vibrating assembly includes a vibrator 51, two movable slots 52 and two compression springs 53, the two movable slots 52 are respectively disposed on two sides of the first screen plate 3, two ends of each compression spring 53 are respectively fixed to a side wall of each movable slot 52 and the first screen plate 3, and the vibrator 51 is disposed on an end of the first screen plate 3. When the vibrator 51 vibrates, the compression spring 53 drives the first sieve plate 3 to rock up and down, so that rice on the first sieve plate 3 can be screened better. The same applies to the vibrating assembly on the second screening deck 4.

As shown in fig. 1 and 4, a blower 6 is disposed on one side of the main body 1, the blower 6 is disposed on the higher side of the first screen plate 3, and a vent hole 13 for communicating the blower 6 with the inside of the main body 1 is further disposed on the side wall of the main body 1. Air-blower 6 inhales with external wind, on the compression blows first sieve 3 in the body 1 through ventilation hole 13 again, can blow out or be collected the big impurity of selecting through first waste material export 11, avoids piling up too much big impurity on first sieve 3 and plugs up the sieve mesh of first sieve 3 to also can blow away or be collected the dust that produces in the screening process through first waste material export 11.

As shown in fig. 1, the direction of inclination of the first screening deck 3 is opposite to the direction of inclination of the second screening deck 4. When the rice on the first sieve plate 3 falls from the lower end of the first sieve plate 3 to the higher end of the second sieve plate 4, the rice rolls from the higher end of the second sieve plate 4 to the lower end, thereby further improving the efficiency of screening.

As shown in fig. 1, a collecting plate 7 is further obliquely arranged at the bottom in the body 1, and a second waste outlet 14 is arranged at the lower end of the collecting plate 7 on the body 1. By providing the inclined collecting plate 7, broken rice, small impurities falling from the second screen deck 4 are discharged or collected through the second reject outlet 14.

As shown in fig. 1, the bottom of the body 1 is further provided with a self-locking universal wheel 8. Through setting up from locking-type universal wheel 8, can conveniently remove body 1 to any place and carry out work.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
