Description

[Detailed description of the invention] Industrial application field The invention is designed to be mounted on the rear of a tractor.
This relates to an operation device for mounted type (tractor-mounted) agricultural machinery (for example, grass straw cutter, tree branch crusher, rice husk crusher, etc.) that transmits power from a PTO shaft.

Conventional technology The rotational speed of the rotary blades, etc. in the above agricultural machinery is as follows:
Appropriate adjustments must be made depending on the type, properties, and supply amount of materials to be processed. To do this, it is necessary to actually supply data to the agricultural machinery and observe its operation and processing status. Conventionally, in the case of a single stationary or self-propelled type equipped with an engine, adjustments were made using the accelerator lever on the material supply section or the handle, and in the case of a mounted type, adjustment was made by the tractor's operation. It was adjusted using the accelerator lever in the seat.

Problems to be Solved by the Invention When supplying materials to agricultural machinery and adjusting the rotation speed of rotary blades, etc. while monitoring the operational processing status, the conventional stationary type or self-propelled type mentioned above does not require a material supply section. Because the accelerator lever was located near the machine, the worker supplying materials could make adjustments on the spot, and there were almost no problems. However, with the conventional mount type mentioned above, the tractor's accelerator lever is located near the tractor's cockpit, away from the agricultural machinery's material supply section, so the operator can easily connect the agricultural machinery's material supply section to the tractor's cockpit. The adjustment had to be made by going back and forth between the two positions several times, which was very troublesome and had poor work efficiency. In addition, if a worker who is supplying materials to agricultural machinery gets his hand caught in the machinery, he cannot reach the accelerator lever of the tractor.
Unable to close the accelerator to make an emergency stop,
It was very dangerous.

The purpose of the present invention is to provide an operating device for a mounted agricultural machine that can solve such conventional problems and improve workability and ensure safety.

Means for Solving the Problems As a means for achieving the above object, the mounted agricultural machine operation device of the present invention is provided at the rear of the tractor A, as can be understood from FIG. 1 showing an embodiment thereof. In the mounted agricultural machine B, which is mounted on the agricultural machine B and transmits power from the PTO shaft 7, the tractor A is connected to the agricultural machine B at an appropriate position via an appropriate connecting device 19 such as an operating rope or a relay wire. It is characterized by being equipped with a control lever 17 that can remotely control the accelerator 2.

Operation When adjusting the rotational speed of the rotary blades, etc. of agricultural machine B, supply data to agricultural machine B and check its operating status, and then operate the operating lever 17 on the spot to adjust the operating rope. etc., to open and close (rotate) the accelerator 2 of the tractor A by pushing and pulling the connector 19 as appropriate. When the accelerator 2 of tractor A opens and closes, the PTO shaft 7 of tractor A rotates at high and low speeds, and the operation of agricultural machine B follows.

Furthermore, when the agricultural machine B is to be brought to an emergency stop, the operating lever 17 may be operated to fully close the accelerator 2 of the tractor A at the same time.

Example Embodiments of the present invention will be described with reference to the drawings.

A is a tractor, 1 is an engine, 2 is an accelerator, 3 is an accelerator pedal connected to the accelerator 2 via an accelerator rod 4, 5 is an accelerator lever, and 6 is for transmitting or blocking the rotation of the engine 1 to the PTO shaft 7 8 is a drive shaft connecting the PTO shaft 7 and the main shaft of the agricultural machine B; 9;
10 is a lower link and an upper link for mounting the agricultural machine B on the rear of the tractor A.

Agricultural machine B in this embodiment is a grass straw cutting machine. 11 is a main shaft, 12 is a rotating blade, 13 is a fixed blade, 14 is a feed roll, 15 is a material supply gutter,
16 is a material discharge gutter.

Reference numeral 17 denotes a control lever for remotely controlling the opening and closing of the accelerator 2 of the tractor A, which is installed near the material supply gutter 15 of the agricultural machine B with a removable mount 18 interposed therebetween, so that it can be swung freely (somewhat tightly). It is attached to the eyes). The mounting position of this operating lever 17 is
In addition to the above, it may be placed anywhere on the agricultural machine B as long as it is within easy reach of the place where the operator frequently works.

Reference numeral 19 denotes a connecting device for connecting the operating lever 17 and the accelerator 2 of the tractor A, and in this embodiment, an operating rope consisting of an inner wire 20 and an outer tube 21 is used. The connector 19 may be any other suitable link device. On one side of the agricultural machine B, the operating rope 19 serving as a coupling device has one end of the inner wire 20 attached to the middle part of the operating lever 17, and
One end of the outer tube 21 is fixed to the mounting base 18, and on the other side of the tractor A,
The other end of the inner wire 20 is removably attached to the accelerator rod 4 by the gripping pieces 22, 22,
The other end of the outer tube 21 is fixed to a bracket 23 which is detachably attached to the body of the tractor A.

In addition, in FIGS. 1 and 3, the gripping piece 2
The inner wire 20 stretched between the inner wire 2 and the bracket 23 is arranged so as not to interfere with the accelerator pedal 3. Also, bracket 23
The operating rope 19, which is suspended over the vehicle, is positioned so as not to interfere with the legs and feet of the worker who depresses the accelerator pedal 3.

Here, the operation of this mounted agricultural machine B will be explained.

First, the operator starts the engine 1 of the tractor A, transmits the rotation of the engine 1 to the PTO shaft 7 by operating the gear lever 6, and then transfers the rotation of the engine 1 to the PTO shaft 7.
The main shaft 11, the rotary blade 12, and the feed roll 14 of the agricultural machine B are rotated through. Then, the rotational speed of the rotary blade 12 of the agricultural machine B is appropriately increased by operating the accelerator lever 5 (stepwise operation).
(At this time, the accelerator pedal 3 is
In conjunction with this, the accelerator 2 is opened. Conversely, the accelerator lever 5 is not interlocked with the accelerator pedal 3. ) Next, the worker leaves the tractor A, goes to the agricultural machine B side, and transfers materials such as grass straw to the material supply gutter 15.
Try supplying it to Therefore, while checking the cutting condition of the material, the rotation condition of the rotary blade 12, the feeding condition of the feed roll 14, etc., the control lever 17 on the agricultural machine B is swung to control the accelerator 2 of the tractor A. Agricultural machinery B with remote control (stepless operation)
The rotational speed of the rotary blade 12 is optimally adjusted. 1st
In the figure, when the operating lever 17 is turned to the left and the inner wire 20 of the operating rope 19 is pulled, the accelerator 2 is opened and the rotational speed of the engine 1 is increased. Conversely, turn the operating lever 17 to the right and release the operating rope 19.
When the inner wire 20 is pressed, the accelerator 2 closes and the rotational speed of the engine 1 decreases. Adjustments are made so that when the operating lever 17 is turned to the far right to fully close the accelerator 2, the rotation of the engine 1 is stopped together with the cutting resistance of the agricultural machine B.

Note that when the tractor A is run after finishing work on the agricultural machine B, the operator rides on the tractor A and operates the gear lever 6 to cut off the rotation transmission to the PTO shaft 7 and connect the lower link 9 and the upper link 10.
The agricultural machine B may be lifted up by the operator and the agricultural machine B may be driven as it is while adjusting the traveling speed using the accelerator pedal 3. There is no need to remove the operating rope 19 from the tractor A and the agricultural machine B. When removing this, it is only necessary to remove the mounting base 18, the gripping pieces 22, 22, and the bracket 23.

Effects of the invention Since the present invention has the configuration as described above, it is possible to immediately adjust the rotation speed of the rotary blade 12 etc. on the spot while working near the agricultural machine B, which improves work efficiency. becomes extremely good.

In addition, while the rotation speed was previously adjusted in stages using the accelerator lever,
The device of the present invention allows the accelerator 2 to be finely adjusted steplessly, and has the synergistic effect of obtaining the optimum rotational speed depending on the type, properties, and supply amount of the material.

Furthermore, if a worker's hand is about to get caught in agricultural machine B, machine B can be immediately stopped on the spot, preventing accidents and ensuring safe work. can.
