Description

Self-priming, self-vibrating and self-sliding rice sieving machine

The utility model relates to a self-suction, self-vibration and self-sliding rice sieving machine, which belongs to agricultural product processing machinery.

At present, rice milling machines in rural areas only remove the hulled chaff during rice milling, but cannot remove stones, stalks, and broken rice mixed in the rice. The rice is subjected to mechanical friction during processing, and the temperature of the rice rises. If the temperature is not lowered in time, it cannot be loaded into the warehouse, otherwise the rice will deteriorate. In order to cool down, farmers stack the processed rice on the field or put it in bags and put it on the open field to cool down naturally. However, the crushed stones, grass, broken rice and part of the chaff in the rice must be blown by hand sieving or electric fans, which is laborious and laborious, and the accuracy of manual screening is not high.

The purpose of this utility model is to overcome the deficiencies in the prior art and provide a self-priming, self-vibrating and self-sliding rice sieving machine, which utilizes the principle of mechanical vibration and aerodynamics, and can be combined with rice milling while rice milling. A rice sieving machine that is screened and cooled by machine docking.

The above purpose is achieved in this way: the self-priming, self-vibrating and self-sliding rice sieving machine includes a hopper, a separation box, a hopper, a separation box, a sieve box and a powder collector, and the hopper and the separation box are connected by a feeding pipe. A downward-sloping separation baffle is welded at the entrance of the separation box. The gap of the separation baffle is located above the exit of the separation box. The outlet is hinged at one end to assemble a heavy center of gravity automatic valve. Connect to the fan shaft hole with an exhaust pipe. The taper mouth of the loading hopper is connected with the upper end of the separation box with bolts, and the feeding amount is controlled by a plugboard. The upper side of the separation box is welded with inclined deflectors. There are several rows of air holes on one side, and the corresponding sides are welded with inclined separation claws at equal intervals. The right side of the separation claw is the air inlet. The connection between the air inlet and the air pipe is controlled by an insert plate, and the downward vertical outlet end is hinged and one end is equipped with a heavy center of gravity automatic valve. Here is the outlet for straw and chaff shells, and the air inlet above it is welded. The baffle with a slope, the notch of the baffle is located above the discharge port, and the feeding pipe and air pipe are fixed with hoops and brackets. The powder collector and the fan are connected with the support by bolts, and the exhaust port of the fan is connected with the feed port of the powder collector. The sieve box composed of upper and lower sieve sheets is connected with the separation box, and the sieve box is fixed on the bracket with bolts. A groove is opened downward on the horizontal section of the upper sieve, the end of the groove is connected with the stone outlet on the sieve box, the lower end of the lower sieve is the outlet of polished rice, and the outlet of broken rice is located below the lower sieve. Bolts are used to connect the lower screen to the screen adjustment plate near the separation box. The installation angles of the upper and lower screens are α=38°, β=42°, and the mesh of the lower screen is finer than that of the upper screen. In order to increase the dust discharge capacity, another blower fan can be added, which can be connected with the air inlet on the separation box and replace the air duct with it.

This self-priming, self-vibrating and self-sliding rice sieving machine has a novel design and an ingenious concept. The upper hopper is connected to the outlet of the rice mill, and the fan switch is turned on, and the milled rice can be screened by the rice sieving machine. The outlet is connected to the pocket, and broken rice and stones flow out from the respective outlets. The broken rice can be used as raw material for brewing or feed, and the rice bran is collected by the powder collector. The polished rice particles separated by this machine are uniform and clean, which ensures the quality of rice and greatly reduces the labor intensity of farmers.
