Abstract
The utility model discloses a fruit tree clipping machine, including action bars, slitting saw and be used for driving the motor of slitting saw, the motor is in order can the dismantlement mode connecting in the upper end of action bars, and the pivot of slitting saw links to each other with the output shaft of motor, include still that one connects the machine box on the motor, the output shaft is placed in quick -witted box, and the pivot is stretched into the machine box and is equipped with the first shaft shoulder, changes the first ring flange of the tip of the axis fixedly connected with, and swing joint has second ring flange and spring holder on the output shaft, and the terminal surface of first ring flange and second ring flange is laminated, and is equipped with the ball grooves that the steel ball was installed in corresponding being used for between the both ends face of laminating each other, is equipped with the spring between second ring flange and the spring holder, is equipped with the second shaft shoulder on the output shaft, the utility model discloses a fruit tree clipping machine can increase to the certain degree after being connected of disconnection output shaft and pivot at the torsion of motor output shaft, prevents that the motor from damaging, guarantees to prune going on smoothly of operation, the improvement operating efficiency.
Description
Technical field
The utility model relates to a kind of clipping device, particularly a kind of fruit tree trimmer.
Background technology
In planting fruit trees, need to carry out cut operation to fruit tree essentially; Existing fruit tree trimmer generally comprises action bars, cast-cutting saw and for driving the motor of cast-cutting saw, motor is connected to the upper end of action bars, the rotating shaft of cast-cutting saw is connected with the output shaft of motor, and during use, driven by motor cast-cutting saw rotates, thus prunes fruit tree; But in pruning process, if fruit tree forms excessive resistance to cast-cutting saw, cast-cutting saw will be caused to move, now the output shaft torsion of motor constantly increases, and may cause motor damage, carrying out smoothly of operation is pruned in impact, reduces operating efficiency.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of fruit tree trimmer, and it can increase at the torsion of motor output shaft the connection to a certain degree disconnecting output shaft and rotating shaft afterwards, prevents motor damage, ensure to prune carrying out smoothly of operation, improve operating efficiency.
Fruit tree trimmer of the present utility model, comprise action bars, cast-cutting saw and for driving the motor of cast-cutting saw, described motor is removably connected to the upper end of action bars, and the rotating shaft of described cast-cutting saw is connected with the output shaft of motor, also comprise one and be connected to machine box on motor, described output shaft is placed in machine box, described rotating shaft is stretched into machine box and is provided with for coordinating first shaft shoulder of locating with machine box, the described the tip of the axis that turns is fixedly connected with the first flange, described output shaft is connected with the second flange and spring base, the end face of described first flange and the second flange is fitted, and between both ends of the surface bonded to each other, be provided with the corresponding ball recess for installing steel ball, spring is provided with between described second flange and spring base, described output shaft is provided with for forming the second spacing shaft shoulder to spring base.
The beneficial effects of the utility model: fruit tree trimmer of the present utility model, when fruit tree forms excessive resistance to cast-cutting saw, the second flange on output shaft moves backward, Compress Spring, makes the end face between the first flange with the second flange separate, and the connection of output shaft and rotating shaft disconnects, the rotation of motor cannot be passed to rotating shaft, thus prevent motor damage, ensure to prune carrying out smoothly of operation, improve operating efficiency.
As further improvement, described spring base is connected by screw thread pair with output shaft; The endoporus of spring base is provided with internal thread, and output shaft is provided with external screw thread, makes spring base by spiral way along the axially-movable of output shaft and location, to adjust the pretightning force of spring, thus completes the control to output shaft torsion under different situations; This structure is simple, easy to use, is easy to regulate.
As further improvement, described first flange and the second flange are evenly distributed with 3-9 ball recess; The quantity of steel ball has the quantity of ball recess consistent; Ball recess is uniformly distributed circumferentially, and ensures stressed even.
As further improvement, the shell of described machine box and motor is one-body molded; Like this, be conducive to improving structural strength, be convenient to production and processing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, in the preferred embodiment, fruit tree trimmer comprises action bars 1, cast-cutting saw 2 and for driving the motor 3 of cast-cutting saw 2, and described motor 3 is removably connected to the upper end of action bars 1, and the rotating shaft 21 of described cast-cutting saw 2 is connected with the output shaft 31 of motor 3, also comprise one and be connected to machine box 4 on motor 3, described output shaft 31 is placed in machine box 4, described rotating shaft 21 is stretched into machine box 4 and is provided with for coordinating first shaft shoulder of locating with machine box 4, the end of described rotating shaft 21 is fixedly connected with the first flange 51, described output shaft 31 is connected with the second flange 52 and spring base 6, the end face of described first flange 51 and the second flange 52 is fitted, and between both ends of the surface bonded to each other, be provided with the corresponding ball recess (not shown) for installing steel ball 8, spring 7 is provided with between described second flange 52 and spring base 6, described output shaft 31 is provided with for forming the second spacing shaft shoulder to spring base 6, described spring base 6 is connected by screw thread pair with output shaft 31, described first flange 51 and the second flange 52 are evenly distributed with 3-9 ball recess, are preferably 6, described machine box 4 is one-body molded with the shell of motor 3.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
