Abstract

theThe invention provides a mechanism for combining hole pricking work as well as ejecting and applying work of solid fertilizers, and belongs to agricultural machines. a left half housing and a right half housing are fixed, a hole pricking piston chamber and a fertilizer feeding chamber which are communicated are formed in the left half housing and a right half housing, and a hole pricking piston is assembled in the hole pricking piston chamber; an external spline sleeve is fixed on the left half housing, and a spline spindle is installed in a trepanning of the external spline sleeve by a needle bearing; a rocking arm is fixed on one end of the spline spindle, and the outer end and the inner end of a connecting rod are respectively connected to the rocking arm and the hole pricking piston in hinged connection; a sun gear, an intermediate gear and a planetary gear are installed in a gear box; the planetary gear is fixed to the external spline sleeve, and the other end of the spline spindle is inserted and fixed in a spline bore on the gear box. Planetary gears are used for driving the integrated mechanism for linking hole pricking as well as ejecting and applying work of solid fertilizers in order to complete synchronous and continuous operations of hole pricking and hole fertilization of solid fertilizers; the mechanism has the characteristics of novel, reasonable and compact structure, high working efficiency, good working quality, low usage failure, and low injury rate of seedlings.

Description

technical field

[0001] The invention belongs to agricultural machinery, and mainly relates to a solid chemical fertilizer injection operation mechanism. Background technique

[0002] Since the hole application method of solid chemical fertilizer has the characteristics of improving the utilization rate of chemical fertilizer, reducing the loss of chemical fertilizer, and reducing the cost of fertilization, this method has been popularized and used in the intertillage topdressing operation of corn seedlings. However, the existing solid fertilizer hole application mechanism has the problems of complex structure, large overall size, poor fertilization accuracy, and high seedling injury rate. Therefore, the development of a new structure of solid chemical fertilizer hole application mechanism is an urgent need for current agricultural production operations. . Contents of the invention

[0003] The purpose of the present invention is to solve the problems existing in the above...
