Description

Electronic orchard shears

(1) technical field

The relevant a kind of electronic orchard shears of the utility model.

(2) background technology

Horticulture is in order to contributing to one's peace of mind of inner tranquility for the people of the grass planting of growing flowers once in a while, but then is the work of supporting one's family for the professional, and how can efficiently carry out work really is a considerable problem.

With regard to professional tool, pruning for the large tracts of land branch can the backpack grass mower be carried out, the flowers and trees of working with great care for the needs work of pruning also has specialty available with orchard shears, but need prune one by one for a large amount of branches the time, does not see that then proper implements can support utilization.

With the fruit tree pruning is example, general grape vine pruning work promptly must be relied on quite a large amount of artificial, can allow the staff save considerable strength though design perfect orchard shears, operate orchard shears for a long time and still can allow staff's palm feel more tired out.

If again with orange tree, the especially hard work of the pruning of annual spring end, because orange tree is only bloomed at old branch, the shoot of emerging then grows vertically upward, only can waste fertilizer yielding positive results then, so the person of planting will inevitably wipe out shoot in annual time spring Mo, but this wooden shoot must expend sizable strength when wiping out, in addition, shoot on the one tree may reach tens, the orangery that generally has economic scale often has hundreds of trees, and for the person of planting, its workload allows the people be difficult to load really.

(5) embodiment

See also shown in Figure 1, it is to be schematic appearance of the present utility model, the utlity model has the shell 10 of a rifle type, at shell 10 1 ends is shank part 12, end is main body section 14 in addition, extend power line 24 at shank part 12 ends, in main body section 14 front group one pivotable blade 34 is housed, concave position in shank part 12 and main body section 14 junctions is formed with and protects bow 16, be assembled with switch 40 protecting bow 16 inboards, and in protect bow 16 in addition shell 10 salient positions of side be formed with the pushing and pressing part 18 of concave arc shape.

Cooperation is referring to the structure configuration schematic diagram of Fig. 2, in shell 10 shank parts 12, be provided with motor chamber 120, main body section 14 inboards then are a Transmission Room 140, in motor chamber 120, be assembled with motor 20, in Transmission Room 140, be assembled with driving gear set 30, the power transmission shaft 22 of this motor 20 extends in the Transmission Room 140, and be provided with a bevel gear 220 in these power transmission shaft 22 ends and be meshed with driving gear set 30, this motor 20 drives driving gear set 30 rotations with power transmission via power transmission shaft 22 to Transmission Room 140, be provided with a rotating shaft 32 in driving gear set 30 by Transmission Room 140 front ends, blade 34 promptly is assembled on this rotating shaft 32, when motor 20 starts after power transmission shaft 22 and driving gear set 30 transmissions, can drive that blade 34 rotates and can be in order to pollard.

In figure, can see in addition at shell 10 and be assembled with a control power turn-on whether microswitch 42 corresponding to the inboard of switch 40 positions, in order to the startup of control motor 20 whether it can be, in addition microswitch 42 sides in switch 40 inboards are provided with a safety plate 44, and whether it can be by start in order to control switch 40.

In shown in Fig. 3,4 being driving gear set 30 configuration schematic diagram of the present utility model, wherein be meshed with the bevel gear 220 of power transmission shaft 22 ends to import power with a bevel gear at driving gear set 30 1 ends as can be seen, driving gear set 30 of the present utility model is by seven train of reduction gears that gear constituted of the A～G among Fig. 3 together with bevel gear 220 integral body, other end then can drive a rotating shaft 32 rotations at it, and the effect of slowing down with lifting torsion can be provided like this.

As shown in Figure 5, blade 34 peripheries of the utility model shell 10 front ends have sawtooth 340 as can be seen in this vertical view, its can sawing mode carry out the pruning of branch, shell 10 front ends in blade 34 1 sides are provided with a main catch 36, it is the sickle shaped of a curved arc, when the utility model is operated, its blade 34 is to rotate with clockwise direction in scheming, so the branch that can allow desire shear is located between blade 34 and the main catch 36, and can not allow branch break away from the shearing scope because of the rotation of blade 34; Shell 10 front ends at blade 34 opposite sides then are provided with a secondary catch 38, this pair catch 38 is the curved arc shape, and be provided with the guide groove 380 of an arc thereon, on this pair catch 38, be assembled with a protecting cover 39 that is the curved arc shape equally, this protecting cover 39 is inside and outside intussusception mode with secondary catch 38 and is provided with, on this protecting cover 39, be formed with the protrusion guide block 390 that matches with guide groove 380, and be formed with in protecting cover 39 leading edges and stir edge 392.

Cooperate shown in Fig. 6,7, the utility model can provide blade 34 appropriate covering by the setting of main catch 36, secondary catch 38 and protecting cover 39, and the shearing scope when limiting its operation is only in blade 34 front sides, and using provides the user preferable safety guarantee.When the utility model during in the user mode of Fig. 6, the guide block 390 of protecting cover 39 just is aligned with an end of guide groove 380; After the utility model usefulness finished, the user can stir protecting cover 39 by stirring edge 392 places, makes guide block 390 along guide groove 380 slippages, makes protecting cover 39 that blade 34 is covered covering wherein again, made the utility model safer when portable and collection.

In being the profile status schematic diagram of switch 40 of the present utility model when being pressed shown in Fig. 8, wherein can see the relative assembling position of this switch 40 and safety plate 44, be formed with a short slot 440 at safety plate 44 towards a side of opening 40, when this short slot 440 aligns switch 40, switch 40 can be pressed and start electronic orchard shears of the present utility model, when safety plate 44 is passed as shown in Figure 9, this short slot 440 promptly staggers mutually with switch 40, switch 40 can't be pressed, can provide the utility model safer operation guarantee like this.

The utility model provides a kind of electronic orchard shears with appropriate design, its power line can connect the accumulator (not shown) to be used, accumulator then can knapsack be born the user on one's body or hang between user's waist, after being exhausted the replaceable accumulator in back, battery power continues to use the utility model, carry out the pruning of branch with the utility model, even work also can not allow user tiger intramuscular ache all day, also can not cause the injury of muscle in long-time operation, its true tool convenience and practicality and be the design of an excellence.
