Description

Portable leaf shearing machine

Technical field

The utility model relates to a kind of device that leaf-cutting is carried out in seedling dish or afforestation, particularly a kind of portable leaf shearing machine of being used for.

Background technology

It is one of modernized agrotechnique of large-scale promotion use that the botanical seedling culturing dish is grown seedlings, in order to cultivate the evenly healthy and strong neat seedling strain of high-quality, avoid seedling strain growth rate too fast, form clubfoot seedling and high pin seedling, need strain prune seedling, a common nursery stage need be pruned repeatedly, currently used trim mode is with manually pursuing dish, by strain, by the leaf pruning, so there are following problems: (1) is because the interior seedling strain density of seedling-cultivating tray is bigger, easily cause the damage of adjacent seedling strain by strain by the leaf pruning, and easily cause the intrusion of disease; (2) strain of seedling-cultivating tray seedling must break away from the nutrition liquid pool in repeatedly pruning, and this nascent root system to the seedling strain has adverse effect, and prune broken leaf down throw to around or scatter on the seedbed, be difficult for removing fully, destroyed the growing environment of seedling strain; (3) to different growing stage, different robustness, the seedling strain of differing heights is pruned, and its yardstick is difficult to grasp or grasps yardstick and differ, and easily causes the seedling strain growth conditions after the pruning to differ, and influences the whole uniformity of seedling strain robustness; (4) artificial operating efficiency of pruning is extremely low.

In order to overcome the drawback of artificial pruning, Kunming, Yunnan Province Zhang Shumao proposed a kind of " tobacco seedling dish leaves shearing machine ", patent No. 99230914.X on February 1st, 1999.It is by frame, and portable tray rack and the rotational shear cutter be located on the frame constitute.By artificial or conveyer belt seedling-cultivating tray is transplanted on during leaf-cutting and carries out leaf-cutting under the rotational shear cutter.But still to be broken away from the nutrition liquid pool by the seedling-cultivating tray pruned, the nascent root system of seedling strain is caused adverse effect.

The technology that is close with the utility model also has: the china national practical new-type patent " gardening trimmer " that Zhejiang Huafeng Electric Tool Co., Ltd. was applied on February 2nd, 2004, the patent No. is 200420003681.9, this patent is that motor passes through the rotation of driving-belt impeller, so blade and cutterhead are done relative motion, form shear action, end of the branch branches and leaves by the cutterhead mouth are rotated the blade excision, under the drive of impeller, broken branches and leaves are thrown out of the discharging opening of cutter head cover, enter in collecting box and the collecting bag.This device drive mechanism complexity, the high speed rotating of impeller contacts with broken branches and leaves generation secondary, consumes a large amount of electric energy, and the blast that the impeller rotation is produced is blown into collecting box and collecting bag, make the collecting bag bulging become the afterbody of big hanging, be not suitable for cut operation is carried out in the seedling strain at the trimmer collecting box.

The utility model content

Technical problem to be solved in the utility model is, overcome weak point of the prior art, provide a kind of simple in structure, the power supply DC-AC two-use, rapidly and efficiently energy-conservation, the direct portable leaf shearing machine that seedling-cultivating tray seedling strain in the botanical seedling culturing pond is carried out leaf-cutting, the broken leaf of collection.

The technical scheme that the utility model is dealt with problems is achieved in that a kind of portable leaf shearing machine, and it mainly is made up of casing, electromotor and blade impeller; It can be the hollow socket join structure of head and collecting hood from the medium position split that casing is one; The close hold spacing bag is installed in the collecting hood, and the cover end and cover body are opened air-vent; Handle is arranged on the head, switch is housed on the handle, electromotor is fixed on the interior support of head, also can be located on the shell of head.Electromotor connects dc source by the switch on the handle; The cutter head mouth down of head, the blade impeller is positioned at the cutter head mouth, and equal with the cutter head mouth; Motor main shaft passes support and is connected with the blade impeller.

For the sake of security, the cutter head mouth of above-mentioned head is provided with safety guard.

Dc source in the said structure can be an accumulator, also can be that alternating current passes through rectification circuit and produces.

Further, above-mentioned electromotor directly adopts alternating current generator, and electromotor directly connects AC power by the switch on the handle.

Compared with prior art, the utility model does not have complicated transmission mechanism, and is simple in structure, and it is lightly convenient to use.The local work that does not particularly have AC power in the open air, the utility model use accumulator also can use.The utility model makes the rotation of blade impeller under driven by motor, realize quick rotary-cut.Blade impeller rotation simultaneously produces centrifugal action to air, the broken leaf under the rotary-cut is sucked in the interior close hold spacing bag of collecting hood, thereby avoid broken leaf to fall into the Miao Zhushang of seedling-cultivating tray, keeps its good growing environment.Simultaneously broken leaf contactor blade impeller has repeatedly not been saved electric energy.Because the distance of the utility model head cutter head mouth and seedling strain can be adjusted arbitrarily with the operative employee, makes the sheared length adjustment of seedling strain quite convenient; Moreover the portable leaf shearing machine of hand-held blade impeller high speed rotating, above the cultivation dish, evenly advance, shearing manipulation can continuously be carried out, greatly improved operating efficiency, and to seedling strain is wounded by stabbing for a short time, do not destroy its growth and development environment, guarantee that rice shoot is whole healthy and strong.
