Technical Field
[0001] The utility model relates to the technical field of broken rice screening, in particular to a broken rice screening device for rice production. Background Art
[0002] When rice is produced, some broken rice needs to be screened out to ensure that the packaged rice grains are plump and uniform. Therefore, a screening device is required to screen the rice. The current broken rice screening device for rice production still has the following problems when in use:
[0003] At present, most of the broken rice screening devices for rice production screen through a vibrating sieve mesh, which causes the qualified rice screened out to accumulate on the top surface of the sieve mesh. Therefore, it is necessary to regularly take out the qualified rice screened out, resulting in non - continuous screening. Moreover, some broken rice is easily blocked in the sieve holes, and the surface of the filter screen lacks vibration, making it difficult to effectively clean it. Summary of the Utility Model
[0004] The purpose of the utility model aims to solve at least one of the above - mentioned technical defects.
[0005] For this reason, an object of the utility model is to provide a broken rice screening device for rice production to solve the problems mentioned in the background art and overcome the deficiencies existing in the prior art.

One side of the rotating joint is fixedly connected with a rolling sieve cylinder. The rolling sieve cylinder is rotationally connected with the feed pipe through the rotating joint. The center of the top of the feed pipe is fixedly connected with a feeding pipe, and the feeding pipe is communicated with the inside of the feed pipe. The top of the rolling sieve cylinder penetrates through one side surface of the fixed box far away from the feed pipe and is rotationally connected with the fixed box. One side of the outer wall of the rolling sieve cylinder penetrating through the outer wall of the fixed box is fixedly connected with a driven gear. One side edge of the top surface of the fixed box near the driven gear is fixedly connected with a fixed inclined plate.

The inclined discharge plate is inclined towards the outlet side of the fixed box. The size of the inclined discharge plate is adapted to the size of the bottom of the inner wall of the fixed box.
[0010] The technical effect achieved by adopting the above solution is that: the inclined discharge plate can completely receive the fallen broken rice and guide the fallen broken rice to slide downwards.
[0011] Preferably, in any of the above solutions, the top of the feeding pipe penetrates through the top surface of the fixed box. A converging hopper is fixedly connected to the top end of the feeding pipe. The converging hopper is of a funnel-shaped structure.
[0012] The technical effect achieved by adopting the above solution is that: the funnel-shaped converging hopper is used to converge and add the added rice into the feeding pipe.
[0013] Preferably, in any of the above solutions, the inner diameter of the inner wall of the rolling sieve cylinder is adapted to the inner diameter of the inner wall of the feeding pipe. The length of the driving shaft is adapted to the sum of the lengths of the rolling sieve cylinder and the feeding pipe.
[0014] The technical effect achieved by adopting the above solution is that: the pushing spiral blades can smoothly push the rice on the inner wall of the feeding pipe into the rolling sieve cylinder, and at the same time, the distribution length of the driving shaft and the pushing spiral blades is matched to improve the stability of support.

[0016] 1. The rice screening device for rice production adds rice into the interior of the feed pipe through the feeding pipe, and then drives the driving shaft to rotate through the first reduction motor. Driven by a number of connecting rods, the pusher scroll blades rotate to push the added rice towards the rolling sieve cylinder. At the same time, the second reduction motor drives the driving gear to rotate, driving the driven gear to rotate, and driving the rolling sieve cylinder to roll, so that the rice pushed into the interior of the rolling sieve cylinder tumbles, screening out broken rice from the rice. Broken rice can be continuously screened out through tumbling, and at the same time, the rotating pusher scroll blades can push the qualified rice screened out towards the top outlet of the rolling sieve cylinder, thereby realizing continuous rice screening and improving production efficiency.
[0017] 2. The rice screening device for rice production enables a number of pushing and guiding inclined blocks to continuously guide and push open a number of knocking hammers through the rotation of the rolling sieve cylinder.
