Abstract
The utility model belongs to the field of garden machinery and particularly relates to a bush cutting head of an engine and an electric garden tool, namely a bush cutter. The bush cutting head comprises an input shaft, a primary driving gear, a primary driven gear, a primary connecting gear, a secondary large gear and a secondary small gear, wherein the input shaft is used for driving the primary driving gear and transferring to the primary driven gear, the primary driven gear is used for driving the primary connecting gear through a spline, the primary connecting gear is meshed with the secondary large gear, and the transmission is transferred from the secondary large gear to the secondary small gear. The bush cutting head is characterized in that the secondary small gear is used for driving a large gear of an output shaft and a small gear of the output shaft, the large gear of the output shaft is used for driving the output shaft, the spline is arranged on the output shaft, and a lower blade seat equipped with a lower blade is driven; and the small gear of the output shaft is used for driving a tertiary large gear, the tertiary large gear is fixed on the output shaft through a bearing, and the tertiary large gear is used for driving an upper blade seat equipped with an upper blade through the spline. The bush cutting head disclosed by the utility model has the advantages of low rotational speed, good safety and convenience in maintenance; and the working efficiency can be greatly improved because the double blades are adopted.
Description
Technical field
The utility model belongs to the graden machine class, specifically is a kind of engine, electronic garden instrument brush saw brush head.
Background technology
In recent years, because the raising of people's living standard makes people's home environment obtain bigger improvement, the development of engine, electronic garden instrument has reduced human labour intensity greatly, has improved production efficiency.The brush head is the output of engine, electronic gardens brush saw, plays crucial effects for the efficient that improves mowing, brush.Common brush head adopts single blade, is applicable to the shrub that branch is tiny, for thick any the shrub of branch, just feels unable to do what one wishes.For the branch on family, the public place greenbelt, if remove unnecessary branch from root, common brush saw and other gardens kind tool all can't be accomplished.Simultaneously because the rotating speed of flail of common brush saw is high, can reach 9000r/min, if when running into big hard thing, machine can produce bounce-back, and human body is produced injury; If when running into small stone, can throw small stone away, others or self are damaged.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, provides that a kind of more reasonable structure, efficient are higher, the more engine of function, electronic garden instrument brush saw brush head.
The technical scheme of the utility model is following:
A kind of engine, electronic garden instrument brush saw brush head comprise power shaft, one-level driving gear, one-level driven gear, one-level connection gear, secondary gear wheel, secondary pinion, and power shaft drives the one-level driving gear; Pass to the one-level driven gear; The one-level driven gear drives the one-level connection gear through spline, and one-level connection gear and the engagement of secondary gear wheel pass to the secondary pinion by the secondary gear wheel; It is characterized in that: the secondary pinion drives output shaft gear wheel and output shaft pinion; The output shaft gear wheel drives output shaft, and spline is arranged on the output shaft, drives the bottom knife seat that bottom knife is housed; The output shaft pinion drives three grades of gear wheels, and three grades of gear wheels pass through bearing fixing on output shaft, and three grades of gear wheels drive through spline and are equipped with on the upper slitter bar of cutter.Because one-level gear drive that cutter is many, so the switched in opposite of cutter and bottom knife, thereby make the brush head can cut shrub, branch etc. smoothly.
The utility model rotating speed is low, less than 600r/min, can not produce bounce-back when running into hard thing, also can not throw small stone away, thereby improve its safety greatly; Owing to adopted double blade, improved operating efficiency greatly; The utility model is rational in infrastructure, and production technology is simple, and is easy to maintenance, except the brush effect, can also play effects such as pruning and deburring, is a wide multi-purpose machine, is fit to family's greening and outdoor greening.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
As shown in Figure 1, a kind of engine, electronic garden instrument brush head comprise power shaft 1, one-level driving gear 2, one-level driven gear 3, one-level connection gear 4, secondary gear wheel 5, secondary pinion 6; Power shaft 1 drives one-level driving gear 2, passes to one-level driven gear 3, and one-level driven gear 3 drives one-level connection gear 4 through spline; One-level connection gear 4 and 5 engagements of secondary gear wheel; Pass to secondary pinion 6 by secondary gear wheel 5, secondary pinion 6 drives output shaft gear wheel 7 and output shaft pinion (omitting among the figure), and output shaft gear wheel 7 drives output shaft 9; On the output shaft 9 spline is arranged, drive the bottom knife seat 11 that bottom knife 10 is housed; The output shaft pinion drives 12, three grades of gear wheels 12 of three grades of gear wheels and is fixed on the output shaft 9 through bearing 13, and three grades of gear wheels 12 drive through spline and are equipped with on the upper slitter bar 15 of cutter 14.
Spline on the utility model output shaft 9 drives bottom knife seat 11 and rotates, and bottom knife 10 usefulness hexagon socket countersunk flat cap head screws are locked on the bottom knife seat 11, rotates thereby drive bottom knife 10; Three grades of gear wheels 12 drive adapter sleeve 16 through spline; Adapter sleeve 16 usefulness screw threads are screwed on the upper slitter bar 15; Utilize spacer pin 17 to block adapter sleeve 16; Make it rotation that can not random device and rotate relative to upper slitter bar 15, cutter 14 is locked on the upper slitter bar 15 through hexagon socket countersunk flat cap head screw, rotates thereby drive cutter 14.Since cutter more than 14 the one-level gear drive, so switched in opposite of cutter 14 and bottom knife 10, thus make the brush head can cut shrub, branch etc. smoothly.
This brush is easy to maintenance, if blade abrasion is serious, needs to repair or change; Only need hex head screw 18 be turned on, take off bottom knife fixed cover 8, take away the bottom knife assembly; Just can twist the screw that is locked on cutter and the bottom knife, thereby blade repairs or replaces; If instrument need add lubricant after using a period of time, only need hexagon socket cap head screw be turned on, add lubricant and get final product.
The utility model is used for engine, electronic garden instrument brush saw.
Claims (3)
