1. An automatic adjustable pot seedling feeding speed device, comprising:
- a conveyor unit comprising a transmission shaft, a conveyor belt, a tensioning shaft, and one or more bearings;
a pot seedlings shovel;
a seedling separation unit configured to separate and correct a feeding posture of a pot seedling;
a detection sensor configured to detect whether the pot seedling reaches a seedling separation position;
a controller;
side plates, wherein the side plates are folded trumpet shape so that an operator can place a number of pot seedlings on the conveyor belt of the conveyor unit at a time; and
support stands,wherein the tensioning shaft and the transmission shaft are configured to keep the conveyor belt in a tensioned work state.

15. A method for operating an automatic adjustable pot seedling feeding speed device, the method comprising:
-
placing, with a pot seedlings shovel of the automatic adjustable pot seedling feeding speed device, a pot seedling on a conveyor belt of a conveyor unit of the automatic adjustable pot seedling feeding speed device; providing, by a detection sensor of the automatic adjustable pot seedling feeding speed device, detection information to a controller of the automatic adjustable pot seedling feeding speed device; responsive to receiving the detection information, providing, by the controller, an instruction to operate a servo motor of the conveyor unit to move the pot seedling along the conveyor belt to a pre-feeding position, wherein the pre-feeding position is located in front of a seedling separation rod of a seedling separation unit of the automatic adjustable pot seedling feeding speed device; detecting, by the detection sensor, the pot seedling in the pre-feeding position; responsive to detecting the pot seedling in the pre-feeding position, providing, by the controller, an instruction to stop the servo motor; when a planter is in a seedling receiving position located under the seedling separation rod, retracting a brake cable of the seedling separation unit so that the seedling separation rod is ejected under the effect of a sleeve tube of the seedling separation unit and a guide post of the seedling separation unit; while the seedling separation rod is ejected, providing, by the controller, an instruction to operate the servo motor so that the pot seedling moves along the conveyor belt and drops in a seedling receiving barrel of the planter under the effect of gravity; while the pot seedling is dropped, correcting, by the seedling separation rod, a feeding posture of the pot seedling by blocking a stem of the pot seedling and leaves of the pot seedling; and after receiving the pot seedling in the seedling receiving barrel, releasing the brake cable so that the seedling separation rod is returned to an initial position in which the seedling separation rod to block additional pot seedlings on the conveyor belt from dropping into the seedling receiving barrel.
