Planting machine with fertilization function

Abstract

The invention discloses a planting machine with a fertilization function. The planting machine comprises a machine frame, walking wheels, a fertilization device, a seeding device and a driving device,wherein the fertilization device comprises a fertilizer box, a plurality of fertilizer boxes in interval arrangement, a plurality of fertilizer pipes and a plurality of hollow fertilization furrow openers; the bottom of the fertilizer box is provided with a discharging opening. The fertilization device also comprises a fertilizer quantity regulating mechanism; the fertilizer quantity regulating mechanism comprises a fertilizer discharging shaft sequentially penetrating through the fertilizer boxes and a regulating element used for driving the fertilizer discharging shaft to move along the self axial direction; a work part used for opening or sealing the discharging opening is arranged on the fertilizer discharging shaft; the work part comprises a plurality of rings of grooves in differentdepth; the grooves are axially arranged along the axial direction of the fertilizer discharging shaft; in the plurality of grooves, except the groove with the smallest depth, the bottoms of the restgrooves are provided with a plurality of bulges at intervals; chain wheels are arranged at two ends of the fertilizer discharging shaft; the chain wheels are connected with an output shaft of the driving device through chains. The planting machine has the advantages that the discharging opening cannot be easily blocked by the fertilizers; the fertilizer flow can be regulated.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a planter with the function of fertilizing. Background technique [0002] With the popularization and application of agricultural technology, the level of agricultural science and technology has been continuously improved, which has greatly improved agricultural production efficiency, resource utilization rate and product added value. As an efficient agricultural machine, the planter has been rapidly developed and widely used. [0003] Although most of the existing planters already have the function of fertilizing, it is difficult to adjust the amount of fertilizing flow according to the needs of users, and the use is very limited. In addition, we know that in the process of crop growth, in order to make it more productive, it is necessary to apply a variety of different fertilizers according to the actual situation, such as nitrogen fertilizer, phosphorus fertilizer, potas...
