The content of the invention

In view of the above-mentioned problems of the prior art, the purpose of this utility model is to provide one kind in not damage to crops and ring Can be realized on the premise of border can improve the hand-held shovel straw articles of weeding ratio from root weeding.

To achieve the above object, the technical solution adopted in the utility model is：A kind of hand-held shovels straw articles, including stroller, The stroller rear portion is provided with handle, and accommodating cavity is provided with the middle part of stroller, is provided with and stretches along its length in the accommodating cavity Contracting arm, the front portion that the telescopic arm stretches out accommodating cavity is bent downwardly, and telescopic arm front end is provided with shovel head；Accommodating cavity upper surface Motor is installed, the output shaft of the motor is extended vertically into accommodating cavity, and output shaft front end is provided with bent axle, in the bent axle Between be hinged with one end of a connecting rod, the other end of connecting rod is hinged on the rear end of telescopic arm.

Preferably, in order that device overall operation is smooth, the crankshaft two end is sat by bearing and is located in accommodating cavity.

Preferably, in order that integral arrangement is compacter, the accommodating cavity is square.

Further, shoveled out in order to facilitate the quick of grass roots, the shovel head front end has the radian being upturned.

It is big that the utility model shovels native depth, it is possible to achieve grass is shoveled from root, so as to reduce the frequency of regular weeding；Utilize It power shovel grass, need not manually exert a force, substantially increase the efficiency of weeding；Weeding process will not cause to damage to crop, also not Harm can be produced to human body and natural environment, there is wide market promotion prospect.

Fig. 2 is that the utility model houses inside cavity structural representation；

In figure, 10. strollers, 11. handles, 12. accommodating cavitys, 21. motors, 21a. output shafts, 22. bent axles, 22a. bearings, 23. connecting rod, 24. telescopic arms, 25. shovel heads.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

As illustrated, a kind of hand-held shovel straw articles, including stroller 10, the rear portion of stroller 10 are provided with handle 11, and stroller 10 middle parts are provided with accommodating cavity 12, are provided with telescopic arm 24 along its length in the accommodating cavity 12, the telescopic arm 24 stretches out The front portion of accommodating cavity 12 is bent downwardly, and the front end of telescopic arm 24 is provided with shovel head 25, the front end ground proximity of shovel head 25；It is accommodating The upper surface of cavity 12 is provided with motor 21, and the output shaft 21a of the motor 21 is extended vertically into accommodating cavity 12, and output shaft 21a front ends are provided with bent axle 22, and among the bent axle 22 and one end of a connecting rod 23 is hinged, and the other end of connecting rod 23 is hinged on flexible The rear end of arm 24.

In use, both hands hold handle 11, stroller 10 is pushed into need the region for shoveling grass；Open the switch drive of motor 21 The output shaft 21a rotations of motor 21, output shaft 21a rotating bands dynamic crankshaft 22 rotates, because one end of connecting rod 23 is hinged on bent axle Among 22, bent axle 22 can pull one end of connecting rod 23 when rotating, bring it about swing, the other end of connecting rod 23 can drive telescopic arm 24 and length direction of the shovel head 25 along accommodating cavity 12 make front and rear stretching motion；Now both hands lift handle 11 slightly upwards The accommodating rear portion of cavity 12 is lifted, can tilt down the front end of telescopic arm 24, stretches out accommodating cavity 12 plus telescopic arm 24 Front portion is bent downwardly so that shovel head 25 and ground have certain angle in itself, the stretching of telescopic arm 24 can drive shovel head 25 to Grass roots bottom shovel soil, grass roots portion is separated with soil layer；When telescopic arm 24 is fully retracted, device is moved forward to next shovel soil Position repeats same step.After grass roots separates with soil layer, it is exposed to the sun under the sun, or weeds is entered using instruments such as rakes Row collects cleaning.It can march forward or draw back when shoveling careless using the present apparatus, the shovel for then completing entire area is careless, clear Science and engineering is made.The wheel of stroller 10 of the present apparatus can use artificial promotion, and the existing power part driving such as motor can also be used, This is not restricted.

Preferably, in order that device overall operation is smooth, the both ends of bent axle 22 are sat by bearing 22a and are located at accommodating cavity In 12.

Preferably, in order that integral arrangement is compacter, the accommodating cavity 12 is square.

Further, shoveled out in order to facilitate the quick of grass roots, the front end of shovel head 25 has the radian being upturned.It is flexible Arm 24 stretch out when can drive shovel head 25 to grass roots bottom shovel soil, grass roots portion is separated with soil layer, now shovel head 25 due to The radian of upper tilting, can be taken advantage of a situation when promoting stroller 10, which will shovel the grass roots opened, releases forward, eliminates subsequently by grass roots from soil In the step of clearing.
