Problems solved by technology

[0003] The invention provides a foot-operated crank rocker sieve for sorting Panax notoginseng seeds, which is used to overcome the shortcomings in the sorting of Panax notoginseng seeds. Before sowing the Panax notoginseng seeds, it is necessary to select seeds with good quality. However, the traditional manual selection method is time-consuming and labor-intensive, which brings about the problem of high cost for Panax notoginseng planting

Embodiment 1

[0014] Embodiment 1: as Figure 1-2 As shown, a foot-operated crank-rocker sieve for sorting Panax notoginseng seeds includes a crank-rocker mechanism and a screening device, wherein the crank-rocker mechanism includes a base 1, a pedal 2, a frame 3, a rocker 4, Bracket 5, crank 6, crank fixing pin 7, fixing sleeve 8, the bracket 5 is fixed on the base 1, the frame 3 is fixed between the brackets 5 on both sides, one end of the pedal 2 is fixed on the bottom of the bracket 5, and the other end is fixed At the bottom of the frame 3, the pedal 2 is connected with the crank 6 through the rocker 4, and the crank 6 shakes with the swing of the rocker 4, and the crank 6 is fixed on the frame 3 and connected with the large pulley 9 through the fixed pin 7; the large belt The pulley 9 is connected with the small pulley 17 through the belt 12, and between the large pulley 9 and the small pulley 17 is a semi-cross transmission; the small pulley 17 is fixed on the lower end of the sieve ...

Embodiment 2

[0015] Embodiment 2: as image 3 As shown, the sieve shaft 14 is provided with three kinds of sieves with different apertures, wherein the flange on the first-level sieve 13 is fixed to the sieve shaft 14 by bolts, the flange on the second-level sieve 15 is fixed to the sieve shaft 14 by bolts, and the third-level sieve is fixed to the sieve shaft 14 by bolts. The flange on the sieve 16 is fixed on the sieve shaft 14 by bolts, and the small pulley 17 is connected with the sieve shaft 14 by a key, and the sieve shaft 14 is connected on the sieve support 19 by a thrust ball bearing 18 .

[0016] Such as Figure 4 As shown, the base 1 and the bracket 5 are connected together by bolts, the pedal 2 and the frame 3 are connected together by the shaft holes, the frame 3 and the bracket 5 are fixed together by the pin holes, the structures of the brackets 5 on both sides are consistent, and the opening The positions of the holes are consistent, and the interference fit with the frame...

Embodiment 3

[0017] Embodiment 3: Because the average particle diameter of Panax notoginseng seed is 5.62mm, the seed greater than 7.5mm basically does not have, and the Panax notoginseng seed particle diameter that is suitable for planter sowing is generally between 5-6.5mm, so the primary sieve 13. The aperture sizes of the secondary sieve 15 and the tertiary sieve 16 are set to 7.5mm, 6.5mm and 5mm respectively, the Panax notoginseng seeds smaller than 5mm will be missed from the tertiary sieve 16, and those larger than 6.5mm will be left in the primary sieve 13, and the impurity in the Panax notoginseng seed is generally the impurity that stem leaf etc. are bigger than seed size, also is stayed in the primary sieve 13, the Panax notoginseng seed that is suitable for sowing is all separated and stays in the secondary sieve 15 middle.

[0018] The crank rocker mechanism in this device is mainly to provide rotating power for the sieve, and it can be manually adjusted in real time. Stabli...

Abstract

The invention relates to a pedal type crank rocker sieve for separation of panax notoginseng seeds and belongs to the field of agricultural machinery. A pedal is pressed with feet to drive a rocker todo reciprocating swing motion, the rocker drives a crank to do revolving motion, a large belt wheel does revolving motion along with the crank, the large belt wheel drives a small belt wheel to rotate through a belt, thus the small belt wheel drives a sieve shaft to rotate, a first-level sieve, a second-level sieve and a third-level sieve rotate along with the sieve shaft, and the separation function for the panax notoginseng seeds is achieved through screening with the three levels of sieves of different mesh numbers. Semi-automation of seed separation is achieved, qualified panax notoginseng seeds can be screened out in a labor saving mode, the separation speed of the panax notoginseng seeds is increased greatly, and labor cost is lowered.

Description

technical field [0001] The invention relates to a foot-operated crank rocker sieve for sorting Panax notoginseng seeds, which belongs to the field of agricultural machinery. Background technique [0002] After the Panax notoginseng seeds are harvested, the quality of the seeds varies, and the seeds are mixed with many debris, broken shells and other debris. When the Panax notoginseng is sown, the quality of the Panax notoginseng seeds directly affects the yield of the Panax notoginseng, so the screening out High-quality Panax notoginseng seeds that meet the planting requirements are very important for Panax notoginseng planting. The traditional method of manually picking the Panax notoginseng seeds, picking out the good quality Panax notoginseng seeds, and removing the sundries mixed in the seeds is time-consuming and laborious. Make the cost of notoginseng planting higher. Contents of the invention [0003] The invention provides a foot-operated crank rocker sieve for s...
