Abstract

The invention discloses a rock removing device for rice. The rock removing device for the rice is composed of a suction fan, a feeding pipe, a machine case, a material returning port, a material box and a discharging port. An inclined screen is arranged in the machine case. The material returning port is formed in the low end of the screen. The material box is arranged below the material returning port. The discharging port is formed in portion below the left side of the machine case. The suction fan is fixed to the upper portion of the machine case. The inlet portion of the suction fan is connected with a separating box which is connected with the feeding pipe. The lower end of the feeding pipe extends into the material box. A vibration screen is obliquely arranged on the machine case and located below the separating box. A high-frequency vibrator is installed on the lower portion of the high end of the screen. A material sliding board is obliquely arranged on the inner wall of the machine case and located below the screen. The low end of the material sliding board is connected with the discharging port. The rock removing device for the rice is simple in structure, rocks in the rice can be removed, and the problems that the rice is accumulated and can not be screened smoothly, so that discharged materials are blocked are solved through the vibration screen and the high-frequency vibrator installed below of the screen.

Description

A device for removing stones from rice

technical field

The invention relates to a grain processing device, in particular to a paddy stone removing device.

Background technique

The stone remover is an important processing equipment used in the grain processing industry. Its function is to remove stones and other sundries from the rice. The removal rate will directly affect the quality of the deep processing of the rice in the later stage. The existing de-stoner machine has better stone-removing effect, but it is prone to the problem of paddy accumulation on the sieve, which cannot be screened smoothly, resulting in the discharge blockage.

Contents of the invention

In order to overcome the above-mentioned defective of the prior art, the object of the present invention is to provide a kind of paddy destoner device.

The present invention is achieved by taking the following technical solutions:

A paddy stone removing device, which is composed of a suction fan, a feeding pipe, a casing, a material return port, a material box, and a discharge port. An inclined sieve is arranged inside the casing, and a material return port is provided at the lower end of the sieve. There is a material box under the mouth, a discharge port is set under the left side of the chassis, and a suction fan is fixed on the upper part of the chassis; the inlet of the suction fan is connected to the separation box; the separation box is connected to the feeding pipe, and the lower end of the feeding pipe extends into the material box The vibrating screen is installed obliquely on the chassis and below the separation box; a high-frequency vibrator is installed under the high end of the sieve; the sliding material plate is obliquely arranged on the inner wall of the chassis and located under the sieve, and the low end of the sliding material plate is connected to the discharge port.

The lower end of the material box is arranged in a funnel shape.

In summary, the present invention has the following beneficial effects: the present invention has a simple structure, and can remove stones from rice, and through a vibrating screen and a high-frequency vibrator under the screen, it solves the problem of paddy accumulation, which cannot be screened smoothly, resulting in material blockage The problem.
