Description

TECHNICAL FIELD

[0001] The application relates to the technical field of rice processing, in particular to a husking device for rice processing. BACKGROUND

[0002] Rice processing refers to the process of removing the hull and skin of paddy and finally producing good-quality rice. The paddy is husked by a husking machine to produce brown rice, and the brown rice is peeled by a rice mill to produce milled rice. According to a search, a paddy husking device for rice processing is disclosed in a patent document with the authorization announcement No. CN214210618U, which comprises a husking mechanism main body, a separation mechanism main body and a screening mechanism main body. The husking mechanism main body is fixedly connected with the separation mechanism main body below, and the separation mechanism main body is fixedly connected with the screening mechanism main body below. When the paddy is poured into the husking mechanism from the feeding port, the paddy is squeezed and torn by the rubber rollers moving at different speeds in opposite directions, so as to achieve the purpose of husking. When the husked paddy passes through the discharge port one, the paddy hulls with lighter quality are blown to the hull discharge port under the action of the air blower, and the milled rice with heavier quality passes through the discharge port two. The milled rice passes through the discharge port two and enters the screening mechanism. The broken rice falls from the screen through the vibration device installed below the screen slot. The rice meeting the screen requirements will roll to the rice discharge port due to the slight inclination of the screen. The screening mechanism separates the qualified rice from the broken rice.

[0003] The above scheme has at least the following disadvantages in actual use: when the paddy is poured into the husking mechanism main body from the feeding port for husking processing, there is a lack of screening and filtering function for large-particle impurities such as gravel mixed in the paddy. These large-particle impurities such as gravel directly enter the husking mechanism main body along with the paddy, which can easily damage the rubber rollers and other parts inside the husking mechanism main body, reducing the quality of rice husking processing.

[0004] Therefore, we propose a husking device for rice processing to solve the above problems. Invention content

[0027] The arc-shaped screen 3 is arranged in the feeding cover 2, and is used for screening and filtering the rice entering the feeding cover 2, so that large-particle impurities such as gravel mixed in the rice are screened and separated, and the large-particle impurities are prevented from entering the rice huller main body 1. The screen holes of the arc-shaped screen 3 are slightly larger than the particle size of the rice particles. The two side outer walls of the arc-shaped screen 3 are both fixedly provided with a supporting slide plate 21.

An L-shaped support 4 is fixedly arranged on the left outer wall of the rice huller main body 1. The L-shaped support 4 is provided with a feeding mechanism for uniformly and quantitatively feeding the rice into the feeding cover 2. The feeding mechanism comprises a feeding cylinder 5, a feeding hopper 6, a discharging pipe 7, a spiral feeding shaft 8 and a feeding motor 9. The feeding cylinder 5 is fixedly arranged on the L-shaped support 4 and located above the feeding cover 2. The feeding hopper 6 is fixedly and communicatively arranged at the top left side of the feeding cylinder 5. The discharging pipe 7 is fixedly and communicatively arranged at the bottom right side of the feeding cylinder 5. The bottom end of the discharging pipe 7 is extended into the feeding cover 2.
