Disclosed is a DC tree branch cutter which comprises a shell, a battery pack installed in the shell, a motor, a transmission gear case and a cutting sawblade installed at the front end of the transmission gear case. The motor is connected with the battery pack through a switch; the sawblade is connected with a motor bevel gear on a motor output shaft of the transmission gear case; the transmission gear case comprises a gear case body, and a two-stage gear cluster and a three-stage gear cluster which are installed in the gear case body; a bevel gear of the two-stage gear cluster is meshed with the motor bevel gear; an upper-layer straight gear of the two-stage gear cluster is meshed with a straight gear of the three-stage gear cluster; and an upper-layer sawing gear of the three-stage gear cluster is meshed with the saw teeth of the cutting sawblade. The upper-layer sawing gear of the three-stage gear is directly meshed with the saw teeth of the cutting sawblade, so the scraps in the saw teeth of the cutting sawblade can be removed and the cutting force of the cutting sawblade can be improved. The DC tree branch cutter is simple in structure and convenient to operate and has big cutting diameter.
Description
Technical field
The utility model relates to the special-purpose cutting tool of a kind of gardening, specifically is meant a kind of direct current branch cutting machine that is used to cut branch stem, leaf.
Background technology
In horticulture-working, traditional-handwork pollard labour intensity is big, inefficiency, and particularly for the trees grafting, manual beta pruning has hinders in trees, thereby influences the survival rate of grafting, is therefore replaced by electronic pruning gradually.Present electric trimmer generally adopts reciprocating saw to prune, and it comprises casing and tooth case, is arranged on the drive motors in the casing, loads onto beat bevel wheel transmission saw blade seat by third-level planetary gear reduction output shaft, cuts thereby the drive reciprocating saw carries out sawing.This structure is because sawing speed is slow, and half is arranged is non-cutting stroke, and consumption power is brought the inconvenience of work greatly.Patent Office of the People's Republic of China's on August 6th, 2003, disclosed Granted publication number was " the electronic orchard shears " of " CN2563916Y ", it comprises shell and is installed on shell interior motor and driving gear set, the shell front end is provided with blade, motor through power transmission shaft with power transmission to driving gear set, thereby driven gear rotates, and then drives blade rotation in order to pollard.But understand residual chip between the sawtooth of this orchard shears blade when cutting, thereby can reduce the cutting force of orchard shears.
The utility model content
The purpose of this utility model is at the defective of above-mentioned prior art and deficiency, for horticulture-working provides a kind of chip removal ability good, and the trees cutting machine that cutting force is big.
The technical measures taked of the utility model are for achieving the above object: this direct current branch cutting machine comprises housing, be installed on the battery pack in the housing, motor, drive gear box and the cutting saw blade that is installed on the drive gear box front end, described motor links to each other with battery pack by switch, described saw blade links to each other with motor bevel gear on the motor output shaft by drive gear box, described drive gear box comprises the tooth casing and is installed on tooth casing interior secondary gear group and tertiary gear group, the bevel gear of described secondary gear group and the engagement of motor bevel gear, the upper strata spur gear of secondary gear group and the engagement of the spur gear of tertiary gear group, the upper strata serrated wheel of described tertiary gear group and the engagement of cutting saw blade.
Described housing is provided with the button that links to each other with switch, in the button bottom anti-self-locking device is installed.
Described anti-self-locking device comprises block, the compression spring of block side and the anti-self-lock switch that links to each other with block that can offset bottom button.
Described drive gear box also comprises the dust excluding plate that is covered on the tooth casing.
Described housing rear side is equipped with the charging jack that links to each other with battery pack.
The utility model adopts the upper strata serrated wheel of tertiary gear and cutting saw blade directly to mesh, can remove the chip in the cutting saw blade sawtooth, can improve the cutting force of cutting saw blade again, have advantage simple in structure, easy to operate, that cutting diameter is big, can be widely used in horticulture-working.Thereby in the button bottom anti-self-locking device being installed can avoid because of being not intended to touch the accident that button causes.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a drive gear box interior schematic diagram.
Fig. 3 is the drive gear box structural representation that is coated with dust excluding plate.
Embodiment
As shown in Figure 1 and Figure 2, the utility model direct current branch cutting machine comprises housing 3, is installed on battery pack 2, motor 18, drive gear box in the housing 3 and the cutting saw blade 13 that is installed on the drive gear box front end, and described cutting saw blade 13 is matched in clearance with the saw blade axis 20 that is fixed on the housing.Described drive gear box comprises tooth casing 11 and is installed on secondary gear group 10 and tertiary gear group 12 in the tooth casing 11, and secondary gear group 10 and tertiary gear group 12 be respectively by being fixed in the tooth casing 11 pivot pin, and is intermittently with pivot pin and cooperates.The bevel gear 9 of described secondary gear group 10 and 17 engagements of motor bevel gear, the upper strata spur gear 16 of secondary gear group 10 and 15 engagements of the spur gear of tertiary gear group 12, the upper strata serrated wheel 14 of described tertiary gear group 12 and the engagement of cutting saw blade 13.As shown in Figure 3,, can above tooth casing 11, cover dust excluding plate 19, thereby improve the service life of drive gear box in order not allow chip enter drive gear box.Described housing 3 rear sides are equipped with the charging jack 1 that links to each other with battery pack 2, and directly external power supply does not need often to change battery to battery pack 2 chargings.Described motor 18 links to each other with battery pack 2 by switch 4, and described housing 3 is provided with the button 5 that links to each other with switch 4, uses for convenience, and this button 5 is loaded on the hole of shaking hands of housing 3.Described button 5 bottoms are equipped with anti-self-locking device, and this anti-self-locking device comprises block 6, the compression spring 8 of block 6 sides and the anti-self-lock switch 7 that links to each other with block 6 that can offset with button 5 bottoms.When block 6 and button 5 bottoms offseted, button 5 can't be pressed; After opening anti-self-lock switch 7, block 6 can be shifted out button 5 bottoms, thereby the use of recovery button 5, close anti-self-lock switch 7 after since the compression spring 8 restoring force can make block 6 get back to button 5 bottoms.
As shown in Figure 3,, can above tooth casing 11, install dust excluding plate 19, to improve the service life of drive gear box in order not allow chip enter drive gear box.
During use, lay anti-self-lock switch 7, push button 5 then, motor 18 energising rotations, bevel gear 9 by motor bevel gear 17 and secondary gear group 10, drive upper strata spur gear 16 and the spur gear 15 of the tertiary gear group 12 that is engaged with, thereby upper strata serrated wheel 14 is rotated synchronously, drive cutting saw blade 13 fast rotational that are engaged with, branch is cut.Because the serrated wheel 14 of tertiary gear group 12 and cutting saw blade 13 directly mesh, can remove the chip in cutting saw blade 13 sawtooth, can improve the cutting force of cutting saw blade again, the machinable maximum gauge is the branch of Φ 33.Should close anti-self-lock switch 7 after finishing using at once.Thereby can avoid because of being not intended to touch the accident that button 5 causes.
