Embodiment Construction

[0013] The following describes in detail the creative implementation of the present invention with reference to the drawings. A combined mechanism for piercing and injecting solid chemical fertilizers. The left half shell 8 is fastened and fixed to the right half shell 1, and the hole piercing piston cavity is formed in the left half shell 8 and the right half shell 1 14 and the fertilizer delivery cavity 13, the lower part of the fertilizer delivery cavity 13 is in communication with the lower side of the hole pricking piston cavity 14, and the hole puckering piston 2 is mounted in the hole pricking piston cavity 14 so as to move up and down and axially. The opposite side walls of the half-shell 8 and the right half-shell 1 are respectively provided with up and down piston anti-rotation chute gaps 17; the left half-shell 8 is fixedly mounted with an external spline sleeve 7, and the needle bearing 6 The spline mandrel 5 is rotatably installed in the sleeve hole of the outer sp...

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] Because the solid-state fertilizer hole application method has the characteristics of improving fertilizer utilization, reducing fertilizer loss, and reducing fertilizer costs, this method has been popularized in the field of corn seedling and topdressing operations. However, the existing solid fertilizer hole application mechanism has the problems of complex structure, large overall size, poor fertilization accuracy, and high seedling damage rate. Therefore, the development of a new structure of solid fertilizer hole application mechanism is an urgent need for current agricultural production operations. . Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art and combine the actual needs of agricultural production operations to...
