Description

[Detailed description of the invention] This invention relates to an achievement reaper.

The achievement reaper consists of a plurality of single reel reapers connected to each other and pulled and driven together. The lotus growth state is an achieved state in which the cutting width is much wider than that possible with a single reaper in one run. Achievement mowers are typically used for mowing golf courses, but they can also be used for other purposes. Typically, the individual reaper reels are driven by wheels or hydraulic motors.

Reapers that are driven by electric motors are also known, but these are operated by a single main power source installed outside the machine, with the reaper being driven and the reaper installed at a specific location. Requires an electrical cord between mains sources;
For this reason, there is a problem in that the reaping range that can be covered by the reaper is naturally limited. There is also a direct current type that does not require an electrical cord to connect to the main power source outside the machine and is equipped with a battery instead, but in this case, it cannot be used continuously over a long period of time. In order to properly drive multiple reapers that are not suitable for use and are in a state of disrepair, it is necessary to install a battery with a considerably large storage capacity, which of course poses a disadvantage in terms of economic efficiency. It was extremely difficult to install it on top. Therefore, an object of the present invention is to be able to drive the reel of each individual reaper by an electric motor by using the power source of a towing vehicle that can be used continuously and stably over a long period of time, and to The object of the present invention is to provide a reaper that can effectively utilize its characteristics.

This invention includes a reaping wheel mounted between a pair of wheels,
A plurality of reel reapers each having an electric motor for driving the reaping IJ wheel; A frame that connects the plurality of reel reapers to each other and is connected to a towing vehicle; A frame connected to a driving means of the towing vehicle; However, it is characterized in that it is composed of an alternating current generator that receives power from the driving means; and a cable that supplies the electric power generated by the alternating current generator to the outside of the electric motor. Therefore, this invention in particular adopts a configuration in which the engine speed of the towing vehicle and the output voltage of the generator change simultaneously, and as the engine speed decreases, the running speed of the towing vehicle and the output voltage of the generator change. However, at the same time, the load applied to the reaper may be reduced correspondingly to the voltage drop required by the electric motor. Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Illustrated in accordance with an embodiment of the invention is a rapid reaper 1 of the type pulled by a tractor 2, the reaping wheels 3 of the individual reel reapers being driven by an electric motor 4. be done.

This electric motor 4 is separately provided for each IJ reaping machine. The drawing shows a reel reaper with a reaping wheel 3 mounted between a pair of wheels 8 and pulled by a jockey wheel 18. However, many other aspects can be explored. For example, a reel reaper can be mounted on a telescoping arm supported as part of the frame. The telescoping arm can be operated by a hydraulic ram connected to the tractor's hydraulic system, allowing the arm to be retracted to retract the reel reaper, which is useful for transporting the mower over the road to different cutting locations. be.
In such a case, the jockey wheel 18 is not necessary. It is preferable for the reaping wheel 3 to have drive connecting portions at both ends, since the motor 4 can be attached to either end. An alternating current generator 5 is integrated into the achievement reaper.

This generator is preferably driven by the engine of the tow vehicle by being connected to the power take-off 6 of the tow vehicle through a step-up transmission by a gearbox or pulley belt mechanism 13, or alternatively by direct connection to the crankshaft of the tow vehicle. Ru. The preferred alternator is 15
It is kilowatt, 3 phase, 200 volts, and uses a 3 phase electric motor. A range of 3/4 to 3 horsepower is preferred, although other alternators and motors may be used.

The alternating current generator only needs to be driven at the rotation speed specified by the manufacturer, and most alternating current generators have a rotation speed of about 150 pm. The alternator can be interposed between the tractor and the frame, either in a housing that is easy to connect to the three-point IJ linkage 7 normally used on tractors, or on the drawbar 9 of the reaper, or alternatively on the Hassei reel. It is installed on the frame that carries the reaper.

Note that the alternator and electric motor are preferably water resistant so that they are not adversely affected when used in bad weather. It is a good idea to provide legs on both sides of the alternator housing that can be moved up and down.

When lowered, that is, when the legs are extended, they serve as supporting legs for the housing when not connected to a tractor. When connecting to a tractor, it is only necessary to raise the reaper, that is, to retract the legs, and the towing vehicle can tow the reaper without any resistance from the legs. The supporting chest, ie, the legs, can be maintained in its raised and lowered position by means of its vertical column and a pin inserted through a hole formed in the cylinder in which the vertical column slides telescopically. Conte.

- A control box 10 is installed on the alternator, and a protective circuit breaker, 1, is integrated into this control box 10. Power from the alternator passes through the control box 10 and reaches the plug box 17. The plug box is mounted on the reaper drawbar, the tractor, the alternator housing, or the frame carrying the reel reaper, at the most convenient location depending on the type and number of reapers in the configuration. The control box 10 has one starter 12 for each electric motor 4. Preferably, the electrical wiring between the alternator plug box 17 and the control box 10 is permanently connected. Power is supplied to the electric motor 4 by a plug 15 inserted into a socket 16 of the control box 10 and by a cable 14 detachably connected to a plug box 17 . Inside the control box 10, there is also a forward/backward switch 19 that changes the rotation direction of the reaper, and a voltmeter 2 that displays the output voltage of the alternator 5.
0 is set. If necessary, a plug 21 for 110 volt electrical equipment may be provided. In another embodiment, the control box 10 can be mounted directly on the towbar 9, eliminating the need for a separate plug box.

The cable 14 may be permanently wired to the control box 10. One cable is a control. cable box 10 to the output of alternator 5, and other cables to a remote switch near the operator's seat. A meter 20 is also provided in the remote switch section. As mentioned above, this invention has a wide range of mowing width in one run when mowing grass on a golf course or other purposes, and the running range is not limited due to the electric cord, and there is no need to take the trouble of replacing or recharging it. It is possible to provide a constant power supply without having to install a battery, which makes it possible to provide an economical Hassei reaper that can be used stably over a long period of time and can be used for a wide range of reaping operations. It is something that

In addition, since we have adopted a configuration in which the output voltage of the towing vehicle's engine and generator change simultaneously, if the engine speed decreases, the traveling speed of the towing vehicle and the output voltage of the generator decrease, and at the same time, the electric motor demands The load applied to the reaping machine can be reduced in response to the voltage drop, and the electric motor does not burn out during use, ensuring good reaping work at all times.
