In order to realize the functions of each device, the structure of each device is described in detail below.
1. Discharging device
The blanking device comprises a first shell 11, a rotating plate 101 and a first driving mechanism for driving the rotating plate 101 and the first shell 11 to rotate relatively. The rotating plate 101 is provided with a rotating plate hole 1011, and the blanking device further comprises a scraping part for scraping soil on the rotating plate 101 into the rotating plate hole 1011, and the lower end part of the first shell 11 is a blanking end. The rotating plate hole 1011 may be a round hole or an elongated hole.
In this embodiment, the first drive mechanism includes a first motor 121, a drive wheel 122, a driven wheel 144, and a first shaft 145. The first rotating shaft 145 vertically passes through and is fixed at the middle part of the rotating plate 101, the first motor 121 is fixed at the outer edge of the first shell 11, the actuating end of the first motor 121 drives the driving wheel 122 to rotate, the driving wheel 122 drives the driven wheel 144 to rotate, and the driven wheel 144 is coaxially arranged at the upper end part of the first rotating shaft 145, so that the first rotating shaft 145 rotates around the central axis. In this embodiment, the driving wheel 122 drives the driven wheel 144 to rotate through the belt 123, and the driving wheel and the driven wheel 144 can be replaced by gears and driven through a chain.
The scraping part comprises a scraping plate 143, the lower bottom surface of the scraping plate 143 is in contact with the upper surface of the rotating plate 101, the distance from the outer circle of the first rotating shaft 145 to the outermost edge of the rotating plate 101 is equal to the length of the lower bottom plate of the scraping plate 143, and therefore all soil on the rotating plate 101 rotates along with the scraping plate 143, and the scraping plate 143 periodically scrapes the soil above the rotating plate 101 into the rotating plate holes 1011. Soil is abutted against one side of the scraping plate 143 when the rotating plate 101 rotates. The rotating plate 101 rotates, and when the lower end surface of the scraping plate 143 passes through the rotating plate hole 1011 for the first time, soil enters the rotating plate hole 1011, so that the first vertical deceleration falling of the soil is realized.
For uniform blanking, the blanking device further comprises a blanking plate 102, wherein the blanking plate 102 comprises a horizontal part 1022 and a hook part 1023, which are attached to the rotating plate 101. One end of the hook 1023 is connected to the outer edge of the horizontal part 1022, and the other end is hung on the upper end surface of the first housing 11. The first rotation shaft 145 passes through the middle of the blanking plate 102 and is fixedly connected through the second bearing 147. The horizontal part 1022 takes the central axis of the first rotating shaft 145 as the center of a circle, and a plurality of blanking holes 1021 are arranged in a circumferential array, and the distance from the blanking holes 1021 to the central axis of the first rotating shaft 145 is equal to the distance from the rotating plate hole 1011 to the central axis of the first rotating shaft 145. The number of the rotating plate holes 1011 is smaller than the number of the blanking holes 1021. In this embodiment, the number of the rotating plate holes 1011 is 1, and the number of the blanking holes 1021 is 6. When the rotating plate 101 rotates for a circle, the scraping plate 143 scrapes part of soil into the rotating plate hole 1011, then the rest of soil rotates along with the scraping plate 143, the soil scraped into the rotating plate hole 1011 rotates along with the rotating plate hole 1011 until the rotating plate hole 1011 sequentially coincides with the 6 blanking holes 1021 up and down, and when the rotating plate 101 is always in a rotating state, the first blanking hole 1021 and the rotating plate hole 1011 vertically coincide, the soil in the rotating plate hole 1011 cannot fall through the blanking holes 1021 once, the falling can be realized after passing through the plurality of blanking holes 1021, and the soil falls below the blanking plate 102 uniformly as much as possible, so that the falling amount of the soil in unit time is reduced. Preferably, the outer edges of the rotating plate 101 and the horizontal portion 1022 are provided with matched arch bridge structures, so that the scraping plate 143 is prevented from entering into a gap at the contact position of the horizontal portion 1022 and the outer edge of the rotating plate 101 during soil scraping, and the rotation of the rotating plate 101 relative to the blanking plate 102 is affected. The blanking plate 102 is divided into a horizontal portion 1022 and a hooking portion 1023, which facilitates the removal of the blanking plate 102 from the first housing 11, cleaning the cavity of the first housing 11 below the blanking plate 102. The cooperation of the blanking plate 102 and the rotating plate 101 realizes the second vertical deceleration falling of the soil.
The lower end of the first rotating shaft 145 is provided with a thread structure 1451, the thread structure 1451 passes through the blanking end of the first shell 11, the inner side surface of the blanking end is a smooth surface, and soil falling into a cavity below the blanking plate 102 enters a gap between the blanking end and the thread structure 1451 and is discharged along with rotation of the thread structure 1451. The structure ensures that the soil is continuously discharged with extremely small amount, and realizes the third vertical deceleration falling of the soil.
Each time the soil falls, the falling amount of the soil in unit time can be reduced, so that the falling amount of the soil from the blanking end is more accurate.
