Abstract

The invention discloses a round arc shrub trimmer. A gasoline engine (1) as power device is arranged at the lower part of the shrub trimmer, a conveyor belt (2) of a transmission device, a two-layer two-section gear (3) and an idle gear (4) are arranged in the middle of the gasoline engine (1), and a fixed round arc machete (5) and a movable round arc machete (6) of a working device are arranged at the upper part of the trimmer; when high-layer high-section gear teeth (17) are engaged with gear teeth (16), the movable round arc machete (6) moves downwards clockwise; when low-layer low-section gear teeth (18) are engaged with the idle gear (4), and the idle gear (4) is engaged with the gear teeth (16), the movable round arc machete (6) moves upwards anticlockwise. The round arc shrub trimmer is driven by the gasoline engine (1), the movable round arc machete (6) does the reciprocating motion around the fixed round arc machete (5) up and down to trim branches and leaves twice by once reciprocating motion, therefore the trimming of the branches and leaves of a spherical shrub can be completed by continuous circulating, to achieve an aim of trimming the branches and leaves of the spherical shrub efficiently and standardly.

Description

Circular arc topiaries machine

Technical field

The present invention relates to landscaping equipment, or be called the clipping device in gardens, the clipping device of especially spherical bush branch and leaf---i.e. circular arc topiaries machine.

Background technology

The equipment that current landscaping device uses is exactly generally large long pruning peace face mower, the plane that large long pruning peace face mower is mainly used in vegetation is pruned, sphere for spherical shrub is pruned, mainly worker employed in a plant nursery prunes by technical ability by rule of thumb, one is inefficiency, and two is prune less attractive lack of standardization.

Summary of the invention

Instant invention overcomes original device inefficiency and prune inaesthetic drawback, providing a kind of circular arc topiaries machine, its structure is simple, being easy to operation, with low cost, easy to maintenance, and also operating efficiency is high, prune the advantages such as specification is attractive in appearance.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:

Circular arc topiaries machine: form primarily of gasoline engine 1, driving-belt 2, two-layer two sections of gears 3, sloth wheel gear 4, fixing circular arc tulwar 5, movable circular arc tulwar 6, casing 7, case lid 8, handle 9, control panel 10, lower brake block 11, upper brake block 12, braces 13, alignment pin 14, chute 15, the gear teeth 16, the high floor height section gear teeth 17, low layer low section of gear teeth 18;

Gasoline engine 1 is fixed on casing 7; Two-layer two sections of gears 3 are fixedly connected with axle, and its axle activity is placed on casing, and axle can rotate on casing; Sloth wheel gear 4 is flexibly connected with axle, and its axle is fixed on casing, and sloth wheel gear 4 can sway; Fixing circular arc tulwar 5 is fixedly connected with casing 7; The activity of movable circular arc tulwar 6 is placed on fixing circular arc tulwar 5, can move up and down under the control of control panel 10 and alignment pin 14 around fixing circular arc tulwar 5;

It is characterized in that: one is two-layer two sections of gears 3 have the high floor height section gear teeth 17 and low layer low section of gear teeth 18; Two is that fixing circular arc tulwar 5 is fixedly connected with alignment pin 14, lower brake block 11, upper brake block 12; Movable circular arc tulwar (6) there are chute (15), the gear teeth (16).

The invention has the beneficial effects as follows: because the present invention devises a kind of circular arc topiaries machine, it is under the drive of electromotor and gear mechanism, movable circular arc tulwar 6 pumping around fixing circular arc tulwar 5 can be made, thus reach object that is efficient and specification topiary branches and leaves.

Fig. 3 is that Fig. 1 fixes the A of circular arc tulwar 5 to cutaway view, and being not containing the cutaway view of movable circular arc tulwar 6, is the view comprising gasoline engine 1, driving-belt 2, two-layer two sections of gears 3, sloth wheel gear 4, casing 7, case lid 8 and braces 13.

Embodiment

First according to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, manufacturing plurality of specifications such as sphere diameter is as required the fixing circular arc tulwar 5 of 0.5 meter, 1.0 meters, 1.5 meters and 2.0 meters etc. and movable circular arc tulwar 6, and the effective length of fixing circular arc tulwar 5 and movable circular arc tulwar 6 equals 1/4th of ball girth; Again according to the size of fixing circular arc tulwar 5, movable circular arc tulwar 6, be made into corresponding casing 7 and case lid 8; And gasoline engine 1, driving-belt 2 and other parts (standard component) carry out the selection of corresponding size and specification in market; Then, shown in Fig. 5 and Fig. 6, process two-layer two sections of gears 3, sloth wheel gear 4 and other parts.

Successively movable circular arc tulwar 6 is installed on fixing circular arc tulwar 5, notes chute 15 activity on movable circular arc tulwar 6 to be installed on alignment pin 14, control panel 10 is installed on alignment pin 14, casing 7 is connected with fixing circular arc tulwar 5; Gasoline engine 1, two-layer two sections of gears 3, sloth wheel gear 4 and attached parts thereof are installed on casing, driving-belt 2 are actively set on corresponding belt pulley; Finally, case lid 8 is installed on casing 7, handle 9 and braces 13 are connected on case lid 8.

The problem that should be noted that, one is that fixing circular arc tulwar 5 wants the same with the shape of movable circular arc tulwar 6 cutter tooth and the tooth pitch of cutter tooth, and the total length of the gear teeth 16 tooth pitch is equal with the tooth pitch of cutter tooth simultaneously; Two is that the basic parameter (modulus, the number of teeth, pressure angle etc.) of the gear teeth 16 is the same with the basic parameter of two-layer two sections of gear 3 gear teeth; Three is that lower brake block 11 will ensure that the gear teeth 16 engage with sloth wheel gear 4; Four is that upper brake block 12 will ensure that the high floor height section gear teeth 17 engage with the gear teeth 16.

Its course of work is: first gasoline engine drives two-layer two sections of gears 3 to rotate counterclockwise by driving-belt and corresponding belt pulley, the high floor height section gear teeth 17 will engage with the gear teeth 16 on movable circular arc tulwar 6, movable circular arc tulwar 6 is moved downward clockwise, but is no more than lower brake block 11; The branches and leaves entered like this between fixing circular arc tulwar 5 and movable circular arc tulwar 6 edge of a knife will be cut off, and sloth wheel gear 4 just idle running;

When two-layer two sections of gears 3 are rotated further, low layer low section of gear teeth 18 engage with sloth wheel gear 4, and sloth wheel gear 4 engages with the gear teeth 16 on movable circular arc tulwar 6, movable circular arc tulwar 6 is moved upward counterclockwise, but is no more than brake block 12; Thus make circular arc topiaries machine once move back and forth twice trimming leaf, going round and beginning again so constantly circulation will complete whole prunings of spherical bush branch and leaf, by topiaries globulate or the first half of shrub to be trimmed to semi-spherical shape (Lower Half feasible planes trimmer is trimmed to cylindrical).

A kind of circular arc topiaries machine provided by the invention, one is that structure is simple, easy to implement, with low cost, easy to maintenance, two is that easy to operate operating efficiency is high, need not prune by technical ability by rule of thumb, three is that to prune specification attractive in appearance, as long as i.e. worker employed in a plant nursery's hand-held circular arc topiaries machine, take a round by topiaries globulate, or the first half of shrub can be trimmed to semi-spherical shape round shrub.
