Description

Road fence flower and tree trimmer

The invention relates to a flower and tree trimmer, belonging to the field of gardening machinery.

In the prior art, machines for trimming flowers and trees generally have no travelling mechanism. When such a trimmer is used to trim flowers and trees, an operator is required to carry the trimmer on his or her shoulder and perform work with the trimmer. At the same time, the trimmer has no mechanism or function for adjusting and changing the trimming height and angle. The hedgerow flowers and trees are mostly densely planted in the bush species, and the distribution distance is long. The hedge trimmer in the prior art is used for trimming hedge flowers and trees, and has low working efficiency and high labor intensity.

The invention aims to provide a flower and tree trimmer which is provided with a traveling mechanism, can trim flowers and trees during traveling and can adjust the trimming height and angle through the mechanism. This pruning machine can accomplish in proper order and prune hedgerow flowers and trees top and both sides, improves the mechanized level of flowers and trees pruning.

The utility model discloses a realize above-mentioned function like this:

the trimmer is provided with a walking mechanism, can be self-propelled, and can also be arranged on various existing walking power machines for use. The power of the trimmer is provided by the walking power machine, and the power system is shared with the walking power machine, or an independent power device can be arranged. The frame of the trimmer can be driven by a hydraulic mechanism or other power mechanisms to lift along the vertical direction and stretch along the horizontal direction; the cutter arranged on the frame also goes up and down and stretches out and draws back along with the cutter. The cutter is hinged with the horizontal telescopic rack, and has an angle adjusting and positioning mechanism, so that the cutting angle can be adjusted at will within a certain range. The devices for driving the cutter to lift, stretch and adjust the angle can be independent mutually, and can also be a comprehensive device with the same function. The cutter has moving blade and fixed blade, which have corresponding toothed edges and toothed antiskid teeth, and under the drive of the driving mechanism, the moving blade reciprocates closely to the fixed blade to cut the branches and leaves of flowers and trees. One or more groups of driving wheels are arranged between the driving wheel and the driven wheel, and the driving wheels are provided with fixed shaft driving wheels arranged on the frame and movable shaft driving wheels arranged on the hinge shafts of the plane connecting rod mechanisms. When the frame and the cutter thereof are lifted and stretched, the position of the movable shaft driving wheel on the hinge shaft of the plane connecting rod mechanism is changed, and the change of the driving distance is compensated. The rotation of the driving wheel transmitted by the driving wheel is realized by a crankshaft connecting rod mechanism or other transmission mechanisms. Which is converted into reciprocating motion of the movable blade relative to the fixed blade. Therefore, various functions of the flower and tree pruning machine are realized.

The embodiment of the utility model is as follows:

the attached figure is a schematic view of a flower and tree trimmer mounted on a small tractor.

The transmission shaft of the tractor drives the driving wheel (1); the driving wheel [1] drives a moving shaft driving wheel [3] and a moving shaft driving wheel [4] which are arranged on a hinge shaft of the plane connecting rod mechanism [5] through a chain [2], and drives driving wheels [7] and [8] through a chain [6], wherein the driving wheels [7] and [8] are a group of fixed shaft driving wheels which are arranged on a rack [22 ]; the transmission wheel [8] drives the transmission wheels [11] and [12] of the moving shaft through a chain [10], and the transmission wheels [11] and [12] are arranged on a hinge shaft of the plane connecting rod mechanism [13 ]; the two groups of plane link mechanisms [5] and [13] are hinged with each wheel; the driving wheel (12) drives the driven wheel (15) through a chain (14); the driven wheel (15) drives a crankshaft connecting rod mechanism consisting of a crankshaft (16) and a connecting rod (17); the connecting rod [17] pushes and pulls the movable blade [18] of the cutter to reciprocate along the fixed blade [19 ]; the cutter fixed blade [19] is hinged with the horizontal telescopic frame [21] through a crankshaft [16 ]; the cutter angle adjusting device [20] is positioned at the hinge joint; the frame [22] is connected with a lifting device [23] and is lifted under the operation of the lifting device; the telescopic device [9] controls the horizontal telescopic rack [21] to stretch; the movable blade (18) and the fixed blade (19) of the cutter are provided with corresponding toothed knife edges, and the knife edge part is provided with sawtooth-shaped anti-skid teeth; when the trimmer moves forward, the branches and leaves of the flowers and the trees enter the toothed knife edges, the movable blade [18] reciprocates and cuts the branches and leaves of the flowers and the trees with the fixed blade [19 ]. When the hedge flowers and trees are trimmed, the top of the flowers and trees can be trimmed by the cutter in a horizontal state; the cutter is in an upward and downward vertical state, and can respectively trim two sides of flowers and trees. By adjusting the angle of the cutter, the flowers and the trees can be trimmed into shapes with any angles. Compared with the prior art, the utility model realizes the mechanization of flower and tree pruning; the hedge trimmer is particularly remarkable in hedge trimming effect, and can greatly improve the working efficiency and reduce the labor intensity.
