Description
Technical field
The present invention relates to horticultural machinery field, is specifically a kind of pruning machine.
Background technology
The cutter head of pruning machine is connected with electromotor by reduction box, shearing function is realized by electromotor band dynamic cutter head, cutter head is primarily of fixed blade, knife section forms, the driving to knife section is realized by cam mechanism between the output shaft of gearbox and knife section, knife section swings and has matched to the shearing of branch with fixed blade, but the pruning machine of prior art is also in following defect: first, in shear history, the cutting edge of blade especially knife section can wear and tear generation burr, knife section must be dismantled with fixed blade and be separated, then respectively knife section and fixed blade are whetted a knife, it just can be made to keep sharp, after sharpening, again knife section and fixed blade are assembled again, it is installed, the process of dismounting is cumbersome, waste time and energy, secondly, eccentric amplitude of fluctuation is less, therefore, so just cause the cutting stroke of blade less, shearing force is also just limited, not ideal enough, sometimes the shearing to some large branches cannot even be completed.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of and knife section just can be kept sharp and the pruning machine being conducive to improving knife section shearing force without the need to knife section and fixed blade being dismantled to be separated.
Technical solution of the present invention is, a kind of pruning machine with following structure is provided, it comprises support, support is provided with drive motors, reduction box, fixed blade and knife section, drive motors and reduction box assembly and connection, knife section coordinates with fixed blade is hinged, and knife section is affixed near the sword face of knife section near the sword face of fixed blade and fixed blade, this pruning machine also comprises fork and connector, the output shaft of fork and reduction box is connected and fixed, front end and the fork of connector are hinged, and rear end is flexibly connected with knife section; Fixed blade is provided with at least one first cutting edge groove near the sword face of knife section; The afterbody of described knife section is provided with projection, and the rear end of described connector is provided with jack, and the projection activity cooperation on described knife section is inserted in the jack of connector end; The side relative with support, the rear end of described connector is also provided with the slide block of evagination, and described support is provided with guide groove, and described skid is engaged in guide groove.
After adopting above structure, pruning machine of the present invention compared with prior art, has the following advantages:
Original cam structure is replaced with swing rod structure, fork is easy to manufacture than cam, the wabbler mechanism that fork and connector are formed makes blade have larger cutting stroke, so just significantly can improve the shearing force of blade, better to the shear effect of branch, and be provided with at least one first cutting edge groove near the sword face of knife section due to fixed blade, like this, just special cutting edge of whetting a knife together is formed in the upper edge of the first cutting edge groove, if knife section wearing and tearing create burr, in the process of knife section swing shearing, when knife section upwards resets, the burr of knife section will enter in the first cutting edge groove, along with knife section continues to move upward, burr on knife section cutting edge can be rubbed off by the special cutting edge of sharpening that the first cutting edge groove top edge is formed, therefore in beta pruning process, the knife section of wearing and tearing can by fixed blade automatic grinding, remain sharp, without the need to knife section and fixed blade are dismantled be separated after whet a knife again, convenient and strength-saving, the shearing force of knife section can be improved like this, solve again the wear problem of knife section.Because connector is in the course of the work the inclination that certain angle can occur when driving knife section to move back and forth, so, the inserting mode with better activity space is adopted between knife section and connector, the driving to knife section can be met, the needs of connector and knife section action separately can be met again.According to the rotary motion trace of knife section, slide block is limited in chute the stability being conducive to being connected between connector with knife section, is also conducive to whole drives structure stability operationally.
As improvement, fixed blade front portion is provided with a breach, and the first cutting edge groove is near the lower limb of breach, and like this, the first cutting edge groove is in this position, best to the sharpening effect of knife section.
As improving again, knife section is provided with at least one second cutting edge groove near the sword face of fixed blade, like this, special cutting edge of whetting a knife together is formed in the upper edge of the second cutting edge groove, like this, during the beta pruning of cutter head portion, the athletic meeting of knife section makes the burr of fixed blade wearing and tearing generation enter the second cutting edge groove of knife section, and rubbed off by the special cutting edge of sharpening that the second cutting edge groove top edge is formed, therefore in beta pruning process, the fixed blade of wearing and tearing can passive blade automatic grinding, avoid burr, remain sharp, without the need to knife section and fixed blade are dismantled be separated after whet a knife again, convenient and strength-saving.
