Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain processing technology, and in particular to a grain processing fine screening and filtration device. Background Technology
[0002] The term "grains" has a broad scope, including rice, wheat, millet, soybeans, and other miscellaneous grains. Grains, including rice, wheat, millet, soybeans, etc., are mainly plant seeds and fruits, and are the traditional staple food of many Asian people. Grains do not only refer to the seeds of grass plants. More precisely, in my country, they can be roughly divided into two categories: ① Cereals: including rice (indica rice, japonica rice, glutinous rice), wheat (wheat, barley, oats, rye), corn, sorghum, millet, foxtail millet, yellow millet, buckwheat, etc.; ② Legumes: including soybeans, broad beans, peas, mung beans, red beans, kidney beans, etc.
[0003] In grain screening machines, only stones can be removed, but excess husks cannot be eliminated, thus reducing the quality of grain screening. Therefore, a grain processing and screening device is proposed to address this problem. Utility Model Content
[0004] The purpose of this application is to provide a grain processing and screening device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this application provides the following technical solution: a grain processing and screening device, comprising a housing, a drive motor fixedly connected to the top of the housing, a rotating rod passing through the interior of the housing driven by the output end of the drive motor, a lever fixedly connected to both sides of the rotating rod, a partition plate rotatably connected to the rotating rod, both sides of the partition plate being fixedly connected to both sides of the inner wall of the housing, a turntable located below the partition plate fixedly connected to the bottom end of the rotating rod, a pressure rod fixedly connected to one side of the turntable, a filter screen located below the partition plate at the bottom end of the pressure rod, a bracket rotatably connected to both sides of the filter screen via a rotating shaft, the bottom end of each bracket being fixedly connected to the bottom of the inner cavity of the housing, one end of the filter screen contacting a top plate, a movable rod fixedly connected to the bottom of the top plate, a bottom plate fixedly connected to the bottom end of the movable rod, a return spring fixedly connected to the bottom of the bottom plate, an installation cylinder fixedly connected to the bottom end of the return spring, and the bottom end of the installation cylinder being fixedly connected to the bottom of the inner cavity of the housing.
[0006] Preferably, both sides of the base plate are slidably connected to the inner wall of the mounting cylinder, and the outer side of the movable rod is slidably connected to the inner wall of the upper port of the mounting cylinder.
[0007] Preferably, the top of the partition is provided with a first screen located on one side of the actuating plate and fixedly connected thereto. The top of the first screen is fixedly connected to the top of the inner cavity of the box. The first screen is placed at an angle. A discharge port is provided on one side of the first screen. The discharge port is located on one side of the box.
[0008] Preferably, a fan is fixedly installed on one side of the housing, and a second screen is fixedly connected to the housing on one side of the fan.
[0009] Preferably, each of the actuating plates is provided with a discharge port below it, and each discharge port is located at the top of the partition.
[0010] Preferably, the top of the box is provided with a feed inlet located on one side and fixedly connected thereto, the side of the box is provided with a discharge outlet, and the bottom of the box is provided with several machine legs.
[0011] Preferably, the filter screens are all placed at an angle, and a stone discharge port is provided below the filter screens.
[0012] In summary, the technical effects and advantages of this utility model are as follows: In this invention, a drive motor drives a rotating rod, which in turn rotates a paddle plate to stir the grains. A fan on one side of the rotating rod blows the grains being stirred, directing the husks towards the first screen. The husks are then discharged from the first screen and the discharge port under the force of the fan. A partition plate is rotatably connected to the rotating rod, and a discharge port is located at the top of the partition plate. The grains that have finished screening are discharged from the discharge port and fall onto the top of the filter screen. At this moment, a turntable fixedly connected to the bottom of the rotating rod drives a pressure rod to rotate. The pressure rod can press the filter screen during rotation. Both sides of the filter screen are rotatably connected via rotating shafts. The device is equipped with supports, each with its bottom fixedly connected to the bottom of the inner cavity of the housing. The filter screen presses down on the top plate, which pushes the movable rod. The movable rod then compresses the return spring on the bottom plate. When the pressure rod rotates to the point where it no longer presses the filter screen, the return spring pushes the bottom plate, which in turn pushes the movable rod. The movable rod then pushes the top plate, causing the filter screen to swing and remove stones from the grain. The filtered grain slides off the top of the filter screen for easy collection. This device not only removes stones but also filters out useless husks, improving the efficiency of the device and effectively improving the quality of grain production. The stone discharge port facilitates the discharge of stones. Attached Figure Description
