In the process, when the fruit generates larger impact displacement and the sliding rod slides to a certain position relative to the spring compression baffle, the limiting ring touches and compresses the spring, so that the impact displacement is restrained.
Thereafter, rotation of the slide cutter causes the cutter to intermittently pop up from the space between adjacent blade bars due to the elastic action, cutting off and removing the stem seedling entering between the seedling guiding roller and the slide cutter. Compared with the original pulling, the seedling removing efficiency is greatly improved, and the breakage rate is obviously reduced.

Detailed Description
Example 1
As shown in FIGS. 1 and 2, a frame 1 of the twin-roll rotary stem seedling cutting type seedling separating device of the embodiment is formed by fixedly connecting a lower two-side main board, two side boards 2-2 on the main board, two side supports 2-1 on the two side boards 2-2 and a spring compression baffle 2-11 between the upper parts of the two side supports 2-1. The frame 1 is provided with a conveying rod lifting chain 3 which surrounds the excavating conveying device, the high end of the conveying rod lifting chain 3 is provided with a motor to drive a rotatable seedling guide roller 3-1, and a seedling guide mechanism 2 is arranged above the seedling guide roller 3-1. The seedling guiding mechanism 2 comprises a group of backward declining springs 2-4 which are distributed at intervals and the inner ends of which are fixedly connected with the spring compression baffle plates 2-11, sliding rods 2-5 which form an axial moving pair with the through holes on the spring compression baffle plates 2-11 are respectively inserted into the springs 2-4, and positioning pin holes which are uniformly distributed at intervals are arranged at the extending sections of the sliding rods 2-5 and used for inserting positioning pins for blocking the limiting rings 2-6 with changeable fixed positions. The horizontal seedling guide rod rotating shafts 2-9 on the side plates 2-2 of the frame 1 below the outer ends of the springs 2-4 are hinged with a group of seedling guide rods 2-7 uniformly distributed at intervals through rotating sleeves 2-10, each seedling guide rod 2-7 consists of a straight section extending backwards and a backward declining section, the upper part of the declining section is fixedly provided with a gravity block 2-8, and the lower part of the declining section is in a circular arc shape matched with the outer circle of the seedling guide roller 3-1. The outer end of the sliding rod 2-5 is hinged with a lug on the straight section of the seedling guiding rod 2-7.
The seedling separating mechanism 4 is located under the seedling guiding roller 3-1, the specific structure of the seedling separating mechanism is shown in fig. 3, 4 and 5, a rotatable sliding cutting cylinder 4-3 which is close to the seedling guiding roller 3-1 is supported under the seedling guiding roller 3-1 through two end transmission cylinder shafts 4-4 which are supported on a bearing seat of the frame 1, and the sliding cutting cylinder 4-3 is composed of two end plates 4-9 and cutter blocking strips 4-5 which are uniformly distributed at circumferential intervals between the two end plates 4-9. The sliding cutting cylinder 4-3 is penetrated with a spring containing groove mounting plate 4-8 with two ends fixed on the vertical frame 4-1, four pit-shaped spring containing grooves 4-2 with top springs 4-6 are respectively fixed in interval holes of the spring containing groove mounting plate 4-8, and spring core shafts 4-11 with upward cutting edges and elastic extension up and down are respectively inserted into the strip-shaped cutters 4-7 and fixedly connected through the mounting plates 4-10 in the top springs 4-6. The section of the cutter blocking strip 4-5 is a right trapezoid with the lower bottom edge outside, and the bevel edge waist faces the rotating direction, and the right angle waist is positioned in the radial direction, so that the cutter blocking strip can be smoothly retracted and forcefully ejected.
As shown in figures 6, 7 and 8, when the fruit of the tuber crop with seedling is picked up and then conveyed to the seedling guiding roller along the conveying rod lifting chain to touch the seedling guiding rod, the fruit is firstly pressed by the seedling guiding rod under the action of the gravity block to be conveyed into the seedling guiding rod under constant pressure; once the follow-up fruits touch and push the front fruits, the seedling guide rod is lifted against the gravity holding force to make a larger space, so that the impact damage and the rolling off of the fruits from the seedling guide roller are avoided, and the fruits are ensured to smoothly enter the seedling guide roller. If the fruit is impacted accidentally and the sliding rod is displaced relatively to the spring relatively, the limiting ring will contact and compress the spring, so that the impact displacement is inhibited and the smoothness of seedling removing operation is ensured. Thereafter, as shown in fig. 9, 10 and 11, the rotation of the sliding cutting cylinder periodically ejects the cutters from the intervals of the adjacent cutter blocking strips due to the elastic action of the top spring, and cuts off and removes the stem seedlings entering between the seedling guiding roller and the sliding cutting cylinder, thereby remarkably improving the seedling removing rate, improving the seedling removing efficiency and obviously reducing the fruit breakage rate. Especially, the stem seedling cutting and removing mode is adopted, so that the stem seedling of the fruit with the seedling, which has larger toughness and thicker diameter, can be removed rapidly and effectively, and the method has ideal adaptability.
In addition to the embodiments described above, other embodiments of the invention are possible. All technical schemes formed by equivalent substitution or equivalent transformation fall within the protection scope of the invention.
