Problems solved by technology

However, since the power drive mechanism of the weeding parts on the power-driven weeder is all composed of a rigid mechanical transmission structure, the transmission structure is complex, there are many operational failures, cumbersome adjustments, heavy weight and high cost, especially on paddy field weeders. It is very difficult to configure the overall configuration of the power drive mechanism of the spring teeth for weeding between seedlings and complete weeding between seedlings, and cannot adapt to and meet the technical requirements for weeding between seedlings in paddy fields

Abstract

An inter-plant weeding spring-tooth flexible shaft driving mechanism of a paddy field weeding machine belongs to the agricultural machinery. A shaft seat and a sleeve are arranged on a machine frame assembly, a rotating shaft is mounted on the shaft seat, a drive sprocket is fixedly mounted in the middle part of the rotating shaft, the end at the outer side of the rotating shaft is connected and equipped with a ball joint coupling, a driving flexible shaft is inserted into the sleeve and both ends thereof are respectively connected with the ball joint coupling and an inter-plant weeding spring-tooth assembly, a power output shaft end of a gear transmission case is fixedly equipped with a drive chain wheel, and the chain is arranged on the drive chain wheel and the drive sprocket in a matching manner. The mechanism is newly and rationally designed, simply structured, and simply and conveniently adjusted, has high efficiency, few failures and wide applicability, and works stably. The invention can be used on a paddy field weeding machine and a dry field weeding machine.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an operating mechanism on a paddy field weeding machine tool. Background technique [0002] Weeding machinery is one of the important working tools in agricultural production water and dry field operations. At present, it is used on weeding machines, including intertillage weeding in upland fields and paddy field weeding machines. The weeding tooth assembly has two structures: follow-up type and power-driven type. Because the power-driven weeding operation tools have better operating performance and higher operating efficiency , has been widely applied. However, since the power drive mechanism of the weeding parts on the power-driven weeder is all composed of a rigid mechanical transmission structure, the transmission structure is complex, there are many operational failures, cumbersome adjustments, heavy weight and high cost, especially on paddy field weeders. It is very difficul...
