Description

a shelling machine

technical field

The utility model relates to an oatmeal production equipment, in particular to an oat shelling machine.

Background technique

With the improvement of people's living standards, higher and higher requirements are put forward for healthy food. Oatmeal is rich in high food-friendly fiber and is gradually accepted and favored by domestic people. However, the production equipment of domestic oatmeal is quite Fewer and immature, so more and more attention is paid to high-quality, high-efficiency oat processing equipment.

In the current oat processing technology, the shelling of oats mainly relies on rolling and shelling, but this method makes the shelling efficiency low, the shelling is not clean, and the material breakage rate is high. The existing oat shelling equipment is difficult to control the rolling gap due to the uneven particle size of the material. If it is too large, it will not be cleaned, and if it is too small, the material will be crushed, resulting in difficulty in subsequent sorting and screening.

Looking for a sheller with reasonable structure, good shelling effect, and reduced material fragmentation has always been one of the contents of the applicant's research.

Utility model content

The purpose of the utility model is to provide a shelling machine with reasonable structure, good shelling effect and low material damage rate aiming at the deficiencies in the prior art.

For realizing above-mentioned object, the technical scheme that the utility model adopts is:

A shelling machine, comprising a barrel body, a centrifugal disc arranged on the upper part of the barrel body, the axis of the centrifugal disc is fixedly connected with a rotating shaft connected with a power device, and the rotating shaft is axially connected with the barrel body, and the centrifugal disc includes The feeding port is set at the center of the shaft, and a channel leading to the outer peripheral surface of the centrifugal disc is arranged around the feeding port, and an impact ring fixedly connected with the barrel is arranged on the outer side of the centrifugal disc peripheral surface, and the outlet of the channel is opposite to Wear the shock ring. Oats enter the inner side of the centrifugal disc from the feed port, and the centrifugal disc rotates under the drive of the rotating shaft. Under the action of centrifugal force, the oats slide from the channel to the outer side of the centrifugal disc, and the oats fly out from the outlet at high speed and hit the impact ring, and the oats on the outer side of the oats are The shell is crushed, and the oats are dehulled.

The inner wall of the impact ring is a conical surface, and the diameter of the conical surface is small at the top and large at the bottom. The gap between the impact ring and the centrifugal disc is small at the top and large at the bottom, which is convenient for the oats to fall and prevents the oats and the casing from flying upwards.

The centrifugal disc includes a feeding port arranged on the upper side, a cylindrical material storage cavity is coaxially arranged between the upper surface and the lower surface of the centrifugal disc, and radial passages are arranged around the material storage cavity. The material storage chamber is used for temporarily storing oats, and the oats have enough space for centrifugal distribution, so that the roots of the oats impact outwards on the impact ring.

The bottom of the centrifugal disc is connected to the rotating shaft through a mounting seat, the mounting seat includes a shaft sleeve arranged at the bottom of the centrifugal disc and fixedly connected to the rotating shaft, a pressure plate is arranged inside the centrifugal disc, and the pressure plate is connected to the rotating shaft through bolts.

The center of the pressure plate is high and the periphery is low. The centrifugal force at the center of the centrifugal disc is zero, and the middle height of the pressure plate avoids physical accumulation at the center of the centrifugal disc, so that the material has centrifugal force and flies out.

The pressure plate is conical, with the apex pointing up.

An upper and lower support is installed in the bucket body, a bearing seat is installed on the support, and the rotating shaft is pivotally connected with the bearing seat.

A storage hopper connected with the barrel body is arranged on the lower side of the impact ring, the top of the storage hopper is connected with the inner wall of the barrel, and a discharge port is arranged at the bottom of the storage hopper.

A top cover is arranged on the top of the bucket body, and a feed pipe is arranged at the center of the top cover, and the feed pipe is inserted into the feed inlet.

Compared with the prior art, the utility model has the following advantages:

Using the impact principle, the channel accelerates the oats in a direction, and hits the surrounding impact ring at a high speed. Due to the characteristics of the material itself, the oats will hit the impact ring with their roots, and then the shell of the oats will break and fall off. The inner core does not directly hit the impact ring, which reduces the chance of oats being broken. The mechanism of the device is reasonable, the shelling effect is good, and the shelling efficiency is high.
