Potato planter intelligent spacing adjustment planting unit

Abstract

The invention provides an intelligent plant spacing-adjusting seeding unit for a potato seeder. The intelligent plant spacing-adjusting seeding unit is characterized in that two ends of a driven shaft fixed with a driven roller are supported on a bracket I; two ends of a driving shaft fixed with a driving roller are located in slideways, and are supported on a bracket II through a tension device; a same conveyer belt fixed with a potato seed bowl on the outer surface is suspended on the driving roller and the driven roller; the upper ends and the lower ends of two sides of a protective cover are fixed on the bracket II and the bracket I on two sides respectively; two sides of a potato guide cylinder are located between the two sides of the protective cover; a gap adjusting device is arranged between the bottom surface of the protective cover and the potato guide cylinder; a conveyer is arranged on a rack and is supported on the ground through a land wheel; a hydraulic motor is arranged at the upper end of a bracket III; the lower end of the bracket III is fixed on the bracket I; an output shaft of the hydraulic motor is coaxially connected with the driving shaft; a controller is arranged on the rack; and a sensor I and a sensor II are arranged on the inner end surface of the land wheel and the end surface of the driving roller respectively. The intelligent plant spacing-adjusting seeding unit is rapid and accurate in plant spacing adjustment and wide in application range.

Description

technical field [0001] The invention provides an intelligent plant spacing adjustment sowing unit of a potato planter, which is mainly used in the potato planter. Background technique [0002] At present, most of the existing potato planting machines fix a simple seed potato bowl on the conveyor chain or conveyor belt. Due to its simple structure, the amplitude of the conveyor chain or conveyor belt cannot be adjusted, and the control of the number of potato seeds in the potato seed bowl is not enough. Precise, it is very easy to cause missed or repeated seeds, which will affect the later growth and development of potatoes. Therefore, Leling Tiancheng Engineering Machinery Co., Ltd. invented a "planting device for bowl and spoon seeding of root crops", authorized patent number: ZL2012200930666. However, it has been found through tests and practical applications that the plant spacing of the potato seeder involved in this patented technology is not easy to adjust, and it is ...
