Among them, a debris removal port corresponding to the position of the coarse filter plate 3 is opened on the right side of the screening box 2, and a sealing block 20 adapted to the debris removal port is fixedly installed on the right side of the screening box 2, and the internal movably connected to the sealing block 20 is a fastening bolt threadedly connected to the screening box 2, which is convenient for opening the sealing block 20 and using the debris removal port to remove large particles of impurities on the coarse filter plate 3. The inner bottom wall of the screening box 2 is fixedly connected to a vibration motor 6, and the output end of the vibration motor 6 is fixedly connected to a movable block 7, and the top of the movable block 7 is rotatably connected to a fine filter plate 9.

Among them, the bottom of the fine filter plate 9 is fixedly connected with a rotating shaft 8, and a rotating hole slidably adapted to the rotating shaft 8 is opened inside the movable block 7, so that the fine filter plate 9 and the movable block 7 can be conveniently connected by passing the rotating shaft 8 through the rotating hole. The inner bottom wall of the screening box 2 is an inclined surface inclined to the right, and a slag discharge port corresponding to the position of the inclined surface is opened on the right side of the screening box 2, so that the fine impurities falling into the inner bottom wall of the screening box 2 can move toward the slag discharge port conveniently.

In this embodiment, the feeding and screening mechanism also includes an electric push rod 10 hinged on the right side of the movable block 7 and hinged to the fine filter plate 9. A conveying cylinder 11 is fixedly connected to the top of the base 1. A material guide pipe 12 is fixedly connected to the side of the conveying cylinder 11 opposite to the screening box 2. A material guide port corresponding to the position of the material guide pipe 12 is opened on the left side of the screening box 2, so that when the electric push rod 10 drives the fine filter plate 9 to rotate, the rice can enter the material guide pipe 12 through the material guide port.

Among them, a conveying motor 13 is fixedly connected to the inside of the conveying cylinder 11, and a auger shaft 14 is fixedly connected to the output end of the conveying motor 13. The conveying cylinder 11 is arranged tilted toward the upper left, and a support rod fixedly connected to the conveying cylinder 11 is fixedly connected to the top of the base 1, so as to facilitate the upward conveying of rice from the bottom of the screening box 2. A feeding pipe 15 is fixedly connected to the bottom of the conveying cylinder 11.

It should be noted that the feeding device for rice storage that can screen out impurities in rice can, through the feeding and screening mechanism, make the eccentric wheel 5 vibrate the coarse filter plate 3 under the drive of the shaking motor 4, thereby screening the rice entering the screening box 2 to remove large particles of impurities in the rice material. After that, the fine filter plate 9 can be vibrated by the driving action of the vibration motor 6, so that broken rice and other fine impurities in the rice material can move downward and separate from the rice, thereby realizing the screening and selection of rice, so that the high-quality rice flowing down can be transported and fed by the conveying cylinder 11.

Embodiment 2: The rejection auxiliary component includes a blower 16 fixedly connected to the left side of the screening box 2, and a chip collecting pipe 17 corresponding to the position of the blower 16 is fixedly connected to the right side of the screening box 2. The right inner wall of the screening box 2 is fixedly connected with a first baffle 18 and a second baffle 19.

It should be noted that the rice storage feeding device, which can screen out impurities in rice, can use the driving action of the blower 16 to generate an air duct between the coarse filter plate 3 and the fine filter plate 9 through the setting of the removal auxiliary component. When the vibration motor 6 vibrates the rice, the empty rice grains and rice leaf debris in the rice material will be stirred up, so that the airflow in the air duct will blow them into the chip collecting pipe 17.

The working principle of the above embodiment is:

The rice storage feeding device capable of screening out impurities in rice can add rice materials from the feed hopper into the screening box 2 when in use, and use the shaking motor 4 to drive the eccentric wheel 5 to rotate, so that the eccentric wheel 5 drives the coarse filter plate 3 to move up and down, so that the coarse filter plate 3 produces a vibration effect, so as to perform the first screening on the rice entering the screening box 2, and remove the large particles of impurities in the rice. In the process of the rice falling, it needs to pass through the air duct generated by the operation of the blower 16, so that the rightward airflow removes the empty rice and rice leaf debris in the falling rice, and cooperates with the vibration motor 4 to drive the eccentric wheel 5 to rotate, so that the eccentric wheel 5 drives the coarse filter plate 3 to move up and down, so that the coarse filter plate 3 produces a vibration effect, so as to facilitate the first screening of the rice entering the screening box 2, and remove the large particles of impurities in the rice. In the process of the rice falling, it needs to pass through the air duct generated by the operation of the blower 16, so that the rightward airflow removes the empty rice and rice leaf debris in the falling rice. The driving action of the machine 6 can realize the vibration of the fine filter plate 9, so that the broken rice and other fine impurities in the rice grain material move downward and separate from the rice, and in the process, the empty rice grains and rice leaf debris remaining in the rice grain material are aroused, so that they come into contact with the air duct again, further improving the impurity removal effect. After the rice screening is completed, the electric push rod 10 can push the fine filter plate 9 to rotate counterclockwise, so that the fine rice on the fine filter plate 9 enters the conveying cylinder 11 through the guide pipe 12, and with the rotation of the auger shaft 14, the rice is transported upward, so that it is discharged from the feeding pipe 15 to realize the feeding operation.
