Double-disk ditching machine
Technical field
The utility model relates to a kind of agricultural machinery, especially relates to a kind of for the degree of depth ditching machine before the fertilising of orchard.Belong to agricultural machinery technological field.
Background technology
Current local special fruit tree industry area increases considerably, the root system of fruit tree is more and more darker, the difficulty of fertilising and labour intensity increasing, applying fruit trees with fertilizer can not rest on the fertilising of shallow position, but need deep ditching, fertilizer is executed the root of tree, allow fruit tree root absorb object that enough nutrition just can reach good quality and high output; Therefore a kind of garden ditching machine that can meet fertilization depth is needed.
Summary of the invention
In order to solve the problem, it is simple that the utility model provides a kind of structure, double-disk ditching machine easy to use.
The utility model, for reaching above object, is achieved through the following technical solutions: the double-disk ditching machine provided is primarily of frame, disk, power transmission mechanism, furrow-opening cutter blade, cover composition.Complete machine is connected by frame, the leading portion of frame has suspension arrangement to be connected with tractor, active force output shaft is connected thus transferring power with the power take-off of tractor, and the dynamic transmission mechanism in rear end of frame, the power take-off of power take-off mechanism both sides is provided with disk.
Power transmission mechanism is made up of spur gear I, spur gear II, spur gear III, power take-off, tape spool symmetrical inclined gear I, helical gear I, helical gear II, power transmission shaft, tape spool symmetrical inclined gear II.
Described active force output shaft is provided with spur gear I, and spur gear I, spur gear II, spur gear III engage in vertical direction successively.Spur gear III and the tape spool symmetrical inclined gear I be arranged on power transmission shaft engages, by the transmission of power on active force output shaft to tape spool symmetrical inclined gear I.At the other end of power transmission shaft, the tape spool symmetrical inclined gear II with tape spool symmetrical inclined gear I symmetry is installed.Tape spool symmetrical inclined gear I and tape spool symmetrical inclined gear II respectively with helical gear I, helical gear II is meshing, and to reach helical gear I, the equidirectional rotation of helical gear II, makes the disk be arranged on helical gear by axle rotate to identical direction.
Described disk is provided with equally distributed multiple furrow-opening cutter blade, described furrow-opening cutter blade cross section is L shape.
Advantage of the present utility model: complete machine adopts the design of two-disc cutter roll structure, and structure is simple, with low cost, and under the environment of orchard, can ditch lower wide 300mm, upper wide 600mm, and the irrigation canals and ditches of depth adjustable 0-550mm, meet orchard and loosen the soil, trench digging, the demand of fertilising.
