The motor shaft 130 is installed in the support structure. The motor shaft 130 may be installed in the main frame 110 as shown in FIG. 1, and may be installed in the support frame 111 or the reinforcing frame. Although not shown in detail, the electric shaft 130 may be rotatably supported by one or more bearings coupled to the support structure.

The elevating motor 133 is also installed in a supporting structure such as the main frame 110. A transmission means such as a sprocket 134 and a chain 135 is installed between the shaft of the elevation motor 133 and the electric shaft 130 And the electric motor shaft 130 is rotated by the elevating motor 133. [

Fig. 5 is a view for explaining the operation of the agricultural high-side working machine shown in Fig. 5, the agricultural high-altitude working machine 100 according to the embodiment of the present invention having the above-described configuration is operated as follows.

Referring to Fig. 5, the agricultural high-speed work machine 100 is disposed close to the fruit water 10. If the fruit number (10) is higher than the height of the worker when pruning the fruit number (10), bagging the fruit (11), harvesting the fruit (11) ) Can be used.

The operator first mounts the work platform 140 and drives the drive motor 121 using a control panel (not shown) as described above so that the number of fruits to be aged 10 to the appropriate position. Next, the control panel is operated to stop the traveling motor 121 so that the agricultural high-altitude working machine 100 stops at an appropriate position to perform the agricultural operation with respect to the fruit water 10.

After the position of the high altitude working machine 100 for agricultural use is selected, the workbench 140 is raised by operating the control panel, so that the operator can perform the agriculture work from the lower side to the upper side of the fruit water 10. The lifting and lowering of the workbench 140 can be realized as shown by solid lines and dotted lines in Fig.

At this time, among the control panels not shown, a switch for raising and lowering the workbench 140 may be installed on the bottom surface of the workbench 140, and a foot switch that can be operated by stepping on the foot may be used.

This is to allow the battery held by the operator in the hand during the agricultural work for the fruit number 10 to raise and lower the work table 140 to an appropriate height without laying down work tools such as a wrist or a bag. So as to obtain the effect that the efficiency of the agricultural work is increased by minimizing the time during which the agriculture work is stopped for raising and lowering.

For reference, although not shown, a safety fence for preventing an operator from falling to the ground 1 may be installed on the work table 140. The safety fence may be provided at the edge of the support portion 141 and the rotation portion 147 of the work table 140, which will be described below.

In addition, when a malfunction occurs in the control panel, the control circuit, the elevation motor 133, etc., or the battery is discharged while the agricultural elevator work machine 100 is performing the agricultural operation, the elevated work table 140 It may not be lowered.

At this time, an escape tool (not shown) may be further provided so that the worker on the workbench 140 can safely descend to the ground 1. The escape tool may be a ladder or an upper end connected to the upper frame 113 and a ladder connected to the main frame 110 at the lower end.

The battery housing 150 connected to the work table 140 is also lifted and lowered by the lifting wire 136 when the work table 140 is lifted and lowered in the course of performing the agricultural work using the agricultural high work machine 100.

This will be described with reference to FIG. 2 and FIG.

Fig. 4 is a schematic diagram for explaining the elevating portion of the elevating machine for agricultural use shown in Fig. Will be described with reference to Figs. 2 and 4. Fig.

Referring first to FIG. 2, the work table 140 and the battery housing 150 are raised and lowered in mutually opposite directions. That is, when the work table 140 is lowered as indicated by a solid line in the drawing, the battery housing 150 is raised and the battery housing 150 is lowered when the work table 140 is lifted as indicated by a dotted line.

This is because the work table 140 and the battery housing 150 are connected as described above, and this connection relationship is shown in FIG. 4 and will be described in detail with reference to FIG.

On the other hand, as shown in FIG. 2, as the workbench 140 is elevated, the horizontal position of the workbench 140 is moved to the middle portion of the support structure. Therefore, as the workbench 140 is elevated, the eccentricity applied to the workbench 140 becomes smaller, so that the stability of the elevator workbench 100 is improved.

4, the work platform 140 slidably connected to the slant frame 112 and the lift pulleys 131 are connected by a lift wire 136, and the lift pulleys 131 are connected to the electric shafts 130 To the battery pulley 132. The battery pack 132 and the battery housing 150 are connected by a battery wire 137.

The battery housing 150 is lifted and lowered along the guide rails 114 when the work table 140 is lifted and lowered along the inclined frame 112 by the rotation of the lifting motor 133. [ At this time, the load WC applied to the work table 140 is transmitted to the battery housing 150 by the shaft 130, the battery wire 137, or the like in the form of a tension T acting on the lifting wire 136 . Conversely, the load WB of the battery housing 150 is also transferred to the work table 140.

Therefore, the load WC of the work table 140 and the load WB of the battery housing 150 are partially canceled by the lift motor 133. In order to rotate the motor shaft 130 according to the degree of offset, The effect of reducing the power can be obtained.

The load WC of the work table 140 corresponds to the weight of the work table 140 itself by the operator or various tools And the weight of the load.

On the other hand, when the tension T applied by the lifting wire 136 at the portion where the lifting wire 136 and the work table 140 are connected by the load WC is separated into the vertical component TV and the horizontal component TH , The load WC applied to the work table 140 is equal to the vertical component force TV.

If the angle formed between the lifting wire 136 and the work table 140 and the lift wire 136 with the imaginary horizontal surface is? 1, the vertical force TV is obtained by multiplying the tension T by sin (? 1) ≪ / RTI >

The work table 140 is lifted and lowered when the tension T and the load of the battery housing WB are balanced when the inertia of the work table 140 and the battery housing 150 and the frictional force generated between various components are neglected The power required for the lifting motor 133 to rotate the electric motor shaft 130 can be minimized.

Assuming that these forces are in equilibrium, the load WC applied to the workbench 140 is in equilibrium with the product of the load of the battery housing WB times sin (? 1) As described above, in order to improve the stability of the agricultural high-altemaking machine 100 as the workbench 140 is elevated, it is larger than 0 degrees and smaller than 90 degrees. When the workbench 140 has a range of 40 to 60 degrees, .

Therefore, a proportional relationship is established between the load WC of the work table 140 and the load of the battery housing WB.

However, the load WC of the workbench 140 varies depending on the number of workers on board and the body weight. Therefore, in order to minimize the power consumed by the lifting motor 133, the load WB of the battery housing 150 must be variable according to the load WC of the work table 140.

To this end, the battery housing 150 may be additionally provided with a weight fixing means 151, and one or more weight adjusting weights 152 may be detachably coupled to the weight fixing means 151. For example, as shown in the drawing, a pin-shaped weight fixing means 151 is provided, and a weight Wb 152 of the battery housing 150 is adjusted by coupling a weight adjusting weight 152 having a through- .

As described above, when the power consumed by the lifting motor 133 is minimized, the consumption of the battery is minimized, so that the time for operating the traveling motor 121 by one charge is increased. Therefore, the agricultural high-altitude working machine 100 can be operated for a longer time during the agricultural work and the time for stopping the work for charging the battery can be saved, so that the efficiency of the agricultural work can be increased.

In the embodiments of the present invention, it is assumed that the traveling motor 121 and the elevating motor 133 use the electric power of the battery. However, even if the traveling motor 121 and the elevating motor 133 are replaced with an engine or the like using fuel, And the efficiency of the agricultural work is increased.

Although not shown, a weight sensing means for sensing a load WC applied to the workbench 140 may be installed on the workbench 140 or the oblique frame 112 so that the load WC varies for the reasons described above. The weight WB of the battery housing 150 can be more easily adjusted by using the weight adjusting weight 152. In this case,

Figs. 6 and 7 are views for explaining the operation of the work bench of the agricultural elevating machine shown in Fig. 1. Fig.

6, there is shown a state in which the agricultural high-altitude working machine 100 is positioned on the paper surface 2 inclined to the other side by? 2. When the agricultural work is performed in the inclined ground 2, since the bottom surface of the work table 140 is also inclined, the efficiency of the agricultural work may be decreased or the risk of the worker falling from the work table 140 may be increased.

In order to prevent this, the work table 140 connects the support portion 141 connected to the inclined frame 112 and the swivel portion 147 with the hinge 146 so that the swivel portion 147 is supported by the support portion 141 As shown in Fig.

At this time, if the turning portion 147 is rotated by the same angle as the inclination angle 2 of the inclined paper 2 with respect to the supporting portion 141, the worker on the work table 140 can easily The agriculture work can be performed.

A fixing bar 142 is formed to protrude from the support portion 141 so that the rotation portion 147 can be fixed to the end portion of the rotation portion 147, The securing means 148 may be releasably coupled to the securing bar 142.

Referring to Fig. 7, there is shown a state in which the agricultural high-altitude working machine 100 is positioned on the ground 3 which is inclined to one side by? 3.

In this case, after the length of the fastening means 148 coupled between the end of the rotary part 147 and the fastening bar 142 is shorter than that shown in FIG. 6, the fastening means 148 is again fastened to the fastening bar 142 And the turning portion 147 is pivoted by the same angle as the inclination angle 3 of the ground surface 3 inclined with respect to the support portion 141, the worker on the work table 140 can be rotated on the turning portion 147 The agriculture work can be performed easily.

Figs. 8 and 9 show a perspective view of an agricultural elevating machine according to another embodiment of the present invention, Fig. 10 shows a front view of the agricultural elevating machine shown in Figs. 8 and 9, And a plan view of the agricultural elevating machine shown in Fig. 9 are shown.

8 to 11, the construction of an elevator for agricultural use according to another embodiment of the present invention will be described.

Referring to FIGS. 8 to 11, the agricultural elevator 200 according to another embodiment of the present invention includes a supporting structure, a traveling part, a work table 240, and a lift part.

The support structure includes a main frame 210, a support frame 211, an inclined frame 212, an upper frame 213, and a guide rail 214. A rack 217 is formed in the inclined frame 212 along the longitudinal direction as shown in the figure.

The traveling part includes a traveling wheel 220, a traveling motor 221 and a front wheel 225. Since the traveling part is the same as the traveling part of the agricultural high-performance working machine 100 according to the embodiment of the present invention, The explanation goes with the previous explanation.

The work table 240 includes a support portion 241, a fixing bar 242, support rollers 243 and 244, a hinge 246, a turning portion 247, and a fixing means 248.

The elevating portion includes a battery pulley 216, a motor shaft 230, a pinion 231, a lifting motor 233, a battery wire 237, and a battery housing 260.

Therefore, when the motor shaft 230 is rotated by the operation of the elevating motor 233, the pinion 231 is moved along the rack 217, so that the work table 240, to which the electric shaft 230 is coupled, And is lifted along the inclined frame 212 as shown in Fig.

At this time, the battery housing 260 is connected by the battery wire 237, as in the embodiment of the present invention described above, so that the load of the work table 240 and the housing of the battery housing 260 are canceled .

However, unlike the embodiment 100 of the present invention, the agricultural elevating machine 200 according to another embodiment of the present invention includes a lifting sheave 115 and a lifting wire 136 The power of the elevating motor 233 is directly applied to the inclined frame 212 via the electric motor shaft 230 and the pinion 231 without using the electric motor 230. [

Therefore, the agricultural elevating machine 200 according to the other embodiment of the present invention can reduce the frictional force between the elevating sheave 115 and the elevating wire 136 and the frictional force between the electric shaft 130 and the bearing during the lifting and lowering of the work table 240. [ There is no loss of the power transmission process due to frictional force or the like. Therefore, the power required by the elevating motor 233 can be further reduced.

In addition, the configuration of the agricultural high-speed work machine 200 according to another embodiment of the present invention is the same as or similar to that of the embodiment 100 of the present invention, and thus redundant description is omitted.
