Agricultural product screening machine

Abstract

The invention relates to an agricultural product screening machine for screening agricultural products according to the size and more detailedly relates to a following agricultural product screening machine. According to the agricultural product screening machine, eight screening rollers are arranged on the upper face of a screening machine body for screening roller arrangement, four screening passages are formed between the screening rollers accordingly, and the rollers making contact with the screening passages are mounted in the mode that the rollers rotate form the bottom to the upper portion, so that damage caused due to frictional resistance of screened bodies passing through the screening passages and the screening rollers is minimized; and separation prevention pieces formed by brushes are arranged on the sides of the screening passages, connecting pieces assembled in an X shape are connected with supporting pieces used for supporting shaft seals of the screening rollers so as to enable left screw nuts and right screw nuts on the two sides to move inwards and outwards so that the distances of the screening passages can be simultaneously adjusted, the distances of the screening passages are precisely and rapidly adjusted accordingly, the agricultural products passing through the screening passages are prevented from breaking away from the screening passages, and thus efficient and safe screening is achieved.

Description

technical field [0001] The present invention relates to an agricultural product screening machine for screening agricultural products by size, and relates in more detail to the following: 8 screening rollers are arranged on the upper surface of the screening machine body to configure screening rollers, thereby forming 4 screening passages between the screening rollers, and from The rollers in contact with the screening channel are installed in a manner of rotating from the bottom to the upper part, so as to minimize the damage of the screened objects passing through the screening channel due to the friction resistance with the screening rollers, and the anti-separation formed by brushes is set on the side of the screening channel. parts, and connect the support piece used to support the shaft seal of the screening roller with the connecting piece assembled in the shape of "X", to install the left screw nut and the right screw nut at the ends of both sides, and make the left scr...

Problems solved by technology

[0002] In the previous agricultural product screening machine, multiple rows of screening rollers are installed on the machine body, so that the screening roller support shaft seal is supported by the shaft handle of the mobile platform, and the screw rod is combined with the screw rod in the threaded hole formed on the mobile platform to make the mobile The platform moves to adjust the distance between the rollers (Korea Utility Model Registration Notice No. 20-0162604), or nuts are respectively attached to the bearing seats attached to the end of the shaft seal of the screening roller, and the thread is combined with the adjusting screw to rotate the adjusting screw, thereby Adjusting the interval between the rollers makes the structure complicated, and the screening operation takes a long time, which is not only troublesome but also inefficient, and due to the friction between the agricultural products passing through the screening channel and the screening rollers, the surface is often damaged. When passing through the screening channel, it often occurs Phenomenon that breaks out of the channel due to friction with the screening roller, causing inconvenience that someone needs to be caught by the side
