Description

[Detailed Description of the Invention] The present invention relates to a stock head guidance device for a reaping machine.

Reapers equipped with a reaping device at the front of the machine and running wheels at the rear are prone to sinking of the machine and unstable running when harvesting soft paddy fields. It is often used with wheels attached, especially in the case of two-wheel, single-row type reapers, the cutting body of the reaping device is formed relatively narrowly to fit between the rows, so the outside of the wheels can be used to separate the left and right parts. It will protrude from the grass.

When reaping work is performed in such conditions, conventional narrow guides push the tips of adjacent uncut grain culms outward and separate them.
Since the stock base cannot be pushed outward at a position immediately in front of the wheels, the stock base is pushed forward and trampled by the protruding parts of the wheels as the aircraft moves forward. Therefore, in the next step, it becomes impossible to raise the grass using the tearing body or the pulling device, making it impossible to reap the grass.

The present invention was devised in view of these circumstances, and in particular, the reaping device and the running wheels are designed so that the stock base of the uncut grain culm is located laterally with respect to the direction of movement of the machine. A guide rod is provided along the guide rod for guiding in the direction, and the tip of the guide rod is fixed to the reaping frame, while the rear end is placed close to and inserted into the wheel recess formed on the side surface of the traveling wheel. Even if the type of reaper is such that the protruding part of the wheels wider than the cutting width forces the stump base of the uncut grain culm to be stepped on, the wheels can be used to push the uncut grain culm outside without knocking over the stump base. The present invention incorporates a stock head guidance device that guides the grain in the direction of the plant, and in the next step, the uncut grain culm can be reliably pulled up and harvested, and the guidance device will not be damaged even if a strong external force is applied to it. Moreover, the grain culms that have entered the inside of the guide rod are allowed to pass backwards without being shed, while still allowing smooth backward running.

Next, an embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a transmission case of a two-wheel, single-row type reaper, and wheels 2 are protruded and supported on both sides of the lower end of the transmission case. The body is supported by wheels 3, 3 attached to an axle 2. And mission case 1
An engine 5 is mounted on an engine frame 4 extending further rearward, and above the engine 5 a handle 6 whose base is fixed to the transmission case 1 extends rearward.

Reference numeral 7 denotes a reaping device provided at the front of the machine, and a reaping frame 8 provided at the lower part of the reaping device 7 is attached to a front frame 9 extending forward from the transmission case 1. Reference numeral 10 denotes a vertical transmission tube erected on one side of the rear part of the reaping frame 8. A lifting case 11 is attached to the upper end of the vertical transmission tube 10, which is inclined to be low in the front and high in the rear.
The middle part of 0 has a base on the upper side of the transmission case 1, and the inclined transmission cylinder 1 extends with a low front and rear posture.
It is connected to the tip of 2.

A binding and discharging device 13 is disposed on the opposite side of the lifting case 11 in the lateral direction, and weeding bodies 14 and 14' are provided in front of the lifting case 11 and in front of the binding and discharging device 13 side.
A grain culm passage is provided between the left and right dividing bodies 14 and 14'. Reference numeral 19 denotes a cutting blade provided below the center of the reaping frame 8 behind the grain culm passage.

The wheels 3, 3 are formed wide, and both outer widths 1 are wider than the width of the tips of the weeding bodies 14, 14'.
Therefore, the outer side of the wheel 3 protrudes laterally from the grass divider 14.

The structure of the grass divider 14 will be described with reference to FIG. 3. The grass divider 14 includes a grass divider plate 15 along the lower part of the pulling case 11, a sled part 16 attached to the reaping frame 8, and a tip of the sled part 16. The divider 17 connects to the sled portion 16 through a perforated plate 18 having multiple mounting holes in upper and lower stages.
The position of the divider 17 can be adjusted up and down by changing the position of the mounting hole. Therefore, when reaping in a field with soil cultivated at the base of the stock, if the divider 17 is used in a lowered position after selecting the mounting hole position, the divider 1
A gap is created between the sled part 16 and the ground behind the sled part 7, allowing soil to drain easily and preventing soil from adhering to the sled part 16.

Incidentally, the divider 17 itself may be provided with a plurality of upper and lower mounting holes, so that the divider 17 itself may be directly mounted to the tip of the sled portion 16 without intervening a perforated plate.

The operating parts such as the pulling case 11 and the cutting blade 19 provided in the reaping device 7 are configured so that power is transmitted from the transmission case 1 through a transmission mechanism installed in the inclined transmission tube 12, the vertical transmission tube 10, etc. It's summery. In addition, the oil pump 2 attached to the outside of the inclined conduction cylinder 12
0 is designed to lubricate the cutting blade 19, etc., and as shown in FIG. 4, the inclined conduction tube 12 has a sealed structure so as to double as an oil tank for lubrication, and 12a is an outer tube, 21 is a transmission shaft, 22 is an oil seal, 23 is a cap, and 24 is a suction pipe connected to the oil pump 20.
By reciprocating the handle 20a provided on the outer cylinder 1
The oil stored between the transmission shaft 2a and the transmission shaft 21 is supplied from the discharge pipe 25 to the lifting case 11, the cutting blade 19, etc., without providing a separate oil tank, and by using the oil pump 20 as the oil tank. Direct mounting allows for a simple and compact structure.

26 is a narrow guide, the tip of which is pivoted to the divider 17 on the side where the lifting case 11 is present, and consists of a rod extending rearward and upward along the side of the fuselage, and its terminal end is supported on the upper part of the vertical transmission cylinder 10. It has been done.

Reference numeral 27 denotes a guide rod provided for guiding the stock base of the uncut grain culm in the lateral and outward direction with respect to the direction of movement of the machine, and its tip is fixed with a bolt 28 on the side of the reaping frame 8 where the lifting case 11 is present. It extends rearward along the sides of the reaping frame 8 and the wheels 3. The rear end of the guide rod 27 is bent inward and inserted into a wheel recess 3a formed on the side surface of the wheel 3, and is brought close to the concave surface of the wheel recess 3a with an opening as shown in the second figure.

Next, the operation of the present invention will be explained.

Grain culm reaping work is carried out with the installed side of the guide rod 27 facing the uncut field, and the grain culm partitioned by the cutting body 14 is pulled up by the cutting blade 19 while receiving the pulling action of the claw of the pulling case 11. Cut and bundle release device 1
3 and are tied together and released to the mowed field.

At this time, the standing grain culms on the adjacent uncut land are pushed laterally by the guidance of the narrow guide 26 and the guide rod 27. At this time, the base of the stock may be trampled by the part of the wheel 3 that protrudes outward from the branching body 14, but since the base of the stock has been guided in the lateral direction of the aircraft by the guide rod 27 in advance, it may fall forward and be trampled. Since the plant is only trampled in a horizontally inclined state without being touched, the tips and stems of the stalks do not fall down significantly. Therefore, in the next step, this laterally inclined grain culm is combed up by the tip of the weeding body 14 and pulled up by the claws of the lifting case 11, so that it can be easily harvested.

Moreover, even if the erect grain culm happens to get inside the guide rod 27, it can pass through the gap with the wheel recess 3a provided at the rear end of the guide rod 27, so that the tip of the grain is blocked at the rear end. There will be no shedding or clogging. Also guide rod 27
When the guide rod 27 is subjected to lateral pressure due to excessive pressure from adjacent erect grain culms or unexpected external force, the end of the guide rod 27 comes into contact with and is supported by the concave surface of the wheel recess 3a, so that it will not be deformed or damaged. .

In addition, when traveling backwards adjacent to the erect grain culm, the terminal end of the guide rod 27 is bent and the wheel recess 3
Since it is inserted into the guide rod 27, the grain culm will not be caught at the end of the guide rod 27 and shedding will occur, and the grain culm can be smoothly removed laterally by the bent end of the guide rod 27.

In this way, the present invention installs a reaping device at the front of the machine.
Further, the reaper is equipped with a running wheel at the rear thereof, and at least the running wheel is laterally wider than the left and right branches of the reaping device, and the reaping device and the running wheel are provided with A guide rod is provided along which guides the stock base of the uncut grain culm in a direction transverse to the direction of movement of the machine, and the tip of the guide rod is fixed to the reaping frame, while the rear end is attached to the side surface of the traveling wheel. By placing the wheel in close proximity to the recess formed in the culm, even if the type of reaper is a type of reaper that has no choice but to step on the stock base of the uncut grain culm due to the protruding part of the wheel that is wider than the cutting width, Since the harvested grain culm is stepped on by the wheels with its stock base being guided laterally and outwardly by the guide rod, the grain culm does not fall forward but tilts laterally, and this lateral tilt is avoided in the next stroke. It is possible to reliably pull up and harvest grain culms in the form of a shape using the divider and pulling claw, and because the rear end of the guide rod is placed close to the wheel recess, even if a strong external force is applied to the guide rod, The rear end of the guide rod is supported by the boss of the wheel, so it will not be damaged.Furthermore, since the rear end of the guide rod faces the wheel recess with a gap, the guide rod will not be damaged during reaping. Even if grain culms get inside the wheel, they can be passed through from the rear end without being shed.Also, when the grain is traveling backwards, the rear end is inserted into the wheel recess, so it can be removed from the guide rod from here. This provides practical effects such as preventing grain culms from entering inward and allowing smooth back travel.
