Fertilization position and transport position changeover mechanism for paddy field fertilization device

Abstract

The invention discloses a fertilization position and transport position changeover mechanism for a paddy field fertilization device and belongs to agricultural machinery. An upper sleeve and a lower sleeve are respectively fixedly arranged on the upper part and the lower part of a guide sleeve; a telescopic pipe sleeved by a pressure spring is inserted into the lower sleeve; a positioning pin is inserted into a lower chute in the lower sleeve; the inner end of the positioning pin is connected with the telescopic pipe; a fertilization boot is assembled on the lower end part of the telescopic pipe; a rotary round tube with short and long boss teeth is inserted into the guide sleeve; a boss-type sleeve is inserted into the upper sleeve; an adjusting hand lever is inserted into an upper chute in the upper sleeve; the inner end of the adjusting hand lever is connected with the boss-type sleeve; a sleeve liner is fixedly arranged on the upper part of the upper sleeve. According to the mechanism, changeover and adjustment of the fertilization position and transport position of a single fertilization device is realized, the adaptive capacity of paddy field operating machines and tools assembled with the fertilization device on different fertilization operating requirements is improved, and the mechanism has the characteristics of novel and reasonable structural design, simplicity and convenience in adjustment and operation and reliability in application.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a position conversion mechanism of a fertilizing device equipped on a rice transplanting and fertilizing machine, a paddy field weeding and fertilizing machine, and a paddy field rotary tillage and soil preparation machine. Background technique [0002] At present, the paddy field fertilization operation is completed by fixing the paddy field fertilization device on various paddy field operation tools to form a composite operation tool, such as rice transplanting and fertilizing machine, paddy field weeding and fertilizing machine, paddy field rotary tillage and land preparation operation machinery, etc. The conversion of the two states of transportation and transportation needs to be realized by changing the height and position of various compound machines and tools, which cannot be controlled separately, especially when fertilization operations can be completed and realized indepen...
