Embodiment 2

[0018] Embodiment 2: as figure 2 As shown, the frame 3 includes a horizontal support frame and a vertical support perpendicular to it. The horizontal support frame is fixed between the support I1 and the support II6 and ensures that the support I1 and the support II6 are parallel to facilitate the normal movement of the crank rocker mechanism. The vertical bracket is a hollow block in the middle. One end of the bottom of the vertical bracket is hinged to the pedal 4, and the other end is fixed on the bracket I2. The lower end of the rocker 7 is connected to the pedal 4 through a ball hinge, and the upper hole of the rocker 7 passes through The bearing is installed on the crank 8 to ensure that the rocker 7 swings with the rotation of the crank 8. The two ends of the crank 8 are fixed on the vertical support. One end of the crank 8 is connected with the large pulley 22 through the fixed pin 9, and then drives the large belt. wheel 22 turns;

Abstract

The invention relates to a foot crank-rocker air screen for sorting radix notoginseng seeds and belongs to the field of agricultural machinery. The foot crank-rocker air screen comprises a crank-rocker mechanism and an air screen device, wherein the crank-rocker mechanism is used for providing power to the air screen device, a rocker is driven by treading a pedal by a worker to swing and also drives a crank to perform circumferential movement so as to drive a large belt wheel to rotate, the large belt wheel drives a small belt wheel to rotate through a belt, and finally, a wind blade rotates as a certain speed to form a stable air flow; the radix notoginseng seeds to be screened are fed through a feeding hole, and under the effect of the air flow to impurities and the seeds, due to different densities, the radix notoginseng seeds flow out from unloading holes on the two sides of a shell, and the impurities are blown out through an impurity outlet, so that screening of the radix notoginseng seeds is realized, the seed sorting speed is increased, and the radix notoginseng sowing efficiency is improved.

Description

technical field [0001] The invention relates to a foot-operated crank rocker air screen used for sorting Panax notoginseng seeds, belonging to the field of agricultural machinery. Background technique [0002] After the Panax notoginseng seeds are harvested, the quality of the seeds varies. At the same time, the seeds are mixed with many light debris such as broken shells and low-quality seeds. It will affect the sowing effect of the seeder and the yield of Panax notoginseng, so it is very important to select high-quality and pure Panax notoginseng seeds that meet the planting requirements for the planting of Panax notoginseng. The traditional method of picking Panax notoginseng seeds by hand, picking out good quality Panax notoginseng seeds, and removing the sundries mixed in the seeds at the same time is time-consuming and laborious, and the traditional electric grain air screen cannot meet the needs of field work. need. Contents of the invention [0003] The invention...
