[0027] Specifically, the implementation process of compressing and relaxing the nutrient pots is as follows: when placing the nutrient pots and compressing the nutrient pots by the planting cup machine, the transmission chain 202 is driven by the motor to transmit the power, and the engagement of the locking teeth arranged on the telescopic mechanism 2 with the transmission chain 202 causes the telescopic mechanism 2 to move left and right on the frame 1. When the telescopic mechanism 2 moves from right to left, since the double-sided teeth 101 are arranged on the frame 1, the teeth at the lower end of the double-sided teeth 101 engage with the third rotating gear 451 of the left gear set 401, driving the third rotating gear 451 to rotate clockwise, thereby driving the third gear set 441 to rotate counterclockwise, causing the second gear set 431 to rotate clockwise, and causing the first gear set 401 to rotate counterclockwise. 421 rotates counterclockwise, driving the first sliding rack 411 to slide horizontally to the right. Since the structure of the right gear set 402 is the same as that of the left gear set 401 and they are symmetrically arranged on both sides of the telescopic mechanism 2, the right gear set 402 slides horizontally to the left. In addition, the teeth on the outer side of the double-sided teeth 101 mesh with the driving gear 501 for transmission. The driving gear 501 rotates clockwise on the horizontal plane when viewed from above and drives the bevel gear 502 to rotate clockwise, thereby driving the rotating gear 503 and the sprocket 504 to rotate outward, so as to stretch the chain 6 toward the outside of the frame, so that the spring compression assembly 10 completes the compression molding process of the nutrient pot. When the telescopic box assembly moves to the leftmost side, the first cup-setting cam 303 Under the action of the bearing seat, it rotates counterclockwise to push the first opening and closing plate (not shown in the attached figure) at the lower end of the spring compression assembly 10 upward. A cylinder 102 is installed on the frame. The cylinder 102 is placed at the lower end of the rocker arm 304 to lift one end of the rocker arm 304. In addition, a torsion spring (not shown in the attached figure) for resetting the rocker arm is also installed on the rocker arm 304. At the same time, under the action of the cylinder 102 and the second cup-setting gear 321, one end of the rocker arm 304 is separated from the cylinder 102, and the cup-setting cam 305 rotates to push the second opening and closing plate at the lower end of the spring compression assembly 10 upward. At this time, the nutrient pot in the spring compression assembly 10 is placed on the first opening and closing plate and the second opening and closing plate, and the soil filling of the nutrient pot is completed. , wherein the cylinder is placed on one side of the rocker arm 304 and enables the rocker arm 304 to rotate; when the telescopic mechanism 2 moves from left to right, since the double-sided teeth 101 are provided on the frame 1, the teeth at the lower end of the double-sided teeth 101 mesh with the third rotating gear 451 of the left gear set 401, driving the third rotating gear 451 to rotate counterclockwise, thereby driving the third gear set 441 to rotate clockwise, causing the second gear set 431 to rotate counterclockwise, and causing the first gear set 421 to rotate clockwise, driving the first sliding rack 411 to slide horizontally to the left side, and since the structure of the right gear set 402 is the same as that of the left gear set 401 and is symmetrically arranged on both sides of the telescopic mechanism 2, the right gear set 402 slides horizontally to the right side;In addition, the teeth on the outward side of the double-sided teeth 101 mesh with the driving gear 501 for transmission, and the driving gear 501 rotates counterclockwise on the horizontal plane when viewed from above and drives the bevel gear 502 to rotate counterclockwise, thereby driving the rotating gear 503 and the sprocket 504 to rotate inward, realizing the relaxation of the chain 6 toward the inside of the frame, so that the spring compression assembly 10 completes the relaxation process of the nutrient bowl. When the telescopic box assembly moves to the rightmost side, the first cup-setting cam 303 disengages from the bearing seat and rotates clockwise, and the upper end of the first cup-setting cam 303 disengages from the first opening and closing plate, and the first opening and closing plate at the lower end of the spring compression assembly 10 opens downward. At the same time, under the action of the external cylinder, one end of the rocker arm 304 rotates to rotate the cup-setting cam 305 so that the second opening and closing plate at the lower end of the spring compression assembly 10 opens downward, and at this time, the nutrient bowl in the spring compression assembly 10 falls off downward from the spring compression assembly 10 to complete the separation and cup setting. ;

[0028] The telescopic cup planting device of the cup planting machine of this embodiment is provided with a telescopic mechanism and a cup placing mechanism.
