INTRA-PLOT SEED PRINTER SELF-CHECKING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/134198
Kind Code:
A1
Abstract:
An intra-plot seed printer self-checking system, which relates to the technical field of seeding, and is used for detecting the flatness of soil. The system comprises: a rack, wherein supporting legs are arranged at the bottom part of the rack, and rollers are arranged at the bottom part of the supporting legs; and a detection unit, which comprises a guide pipe and infrared emitters that are fixed to the two adjacent side walls of the rack, and water and floating balls that are arranged in the guide pipe, the guide pipe being a "]"-shaped structure that has upward-facing opening. When the rack is in a horizontal state, the floating balls are arranged in vertical parts at two ends of the guide pipe under the buoyant action of the water; infrared receivers are arranged at two ends of the side walls of the rack on which the infrared emitters are mounted; the two infrared receivers and the infrared emitters are located on the same straight line; and a shading belt that blocks the linear propagation of infrared rays is arranged in the middle of the floating balls. According to the present invention, the inclination state of the rack may be detected, and seeding precision is thus guaranteed.
