An air supply component and a grain raising device for rice planting and harvesting

Abstract

The invention discloses an air supply assembly, comprising a bottom plate and a partition plate, the partition plate is vertically fixed and installed above the bottom plate; and a motor, the motor is horizontally fixed on the upper part of the partition plate, and the output end of the motor is connected with a crankshaft; and a rotating shaft , the rotating shaft passes through the middle of the partition board and is rotatably connected with it, and a fan is fixed at one end of the rotating shaft; the grain raising device for rice planting and harvesting includes an air supply assembly and a storage barrel fixed on the bottom plate, as well as a conveying assembly and a screening assembly. , Vibration component; the fan in the air supply component is driven to rotate and supply air by the motor, and the conveying component transports the grains in the storage bucket upwards, and falls freely when transported to the top of the fan, and the falling grains pass through the fan. The heavy grains are separated from the light weight shriveled husks to achieve the separation effect; at the same time, the conveying component drives the vibration component to drive the screening component to screen the fallen grains, which can achieve the effect of removing shriveled husks and stones at the same time.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an air supply assembly and a grain raising device for rice planting and harvesting. Background technique [0002] Yanggu is a type of wind selection. The principle is to use the density difference between the grain and the chaff and impurities to separate or remove the chaff by wind or airflow. [0003] When the mass is a fixed value, the object with low density has a large volume, like a goose feather, the suspension time is long, the falling speed is small, and the distance blown away by the wind is farther. In contrast, objects with high density are small in size, fall quickly, and are blown away by the wind closer; thus achieving the effect of separation and sorting. [0004] At present, most of the existing grain raising devices can only supply air, which requires manual lifting of the grain, which is time-consuming and labor-intensive. [0005] The publication number...

Problems solved by technology

[0004] At present, most of the existing grain lifting devices can only supply air, and need to manually raise the grain, which is time-consuming and laborious

[0005] The publication number is CN110586479A, and the invention patent named "a high-efficiency grain sorting equipment" uses arc-shaped blocks, contact plates, connecting rods and mounting plates to periodically vibrate the mounting frame, thereby driving the vibration of the screen to achieve screening Purpose, its shortcomings are: 1. When the screen is blocked by larger wild fruits or stones and cannot be screened normally, the equipment cannot clean the screen alone; 2. The screen can only shake up and down and cannot reciprocate left and right; 3. 、When the grain is blown by winnowing and falls on the screen, there is no baffle around it, and it is easy to fall out of the screen and mix into the screened grain
