Description

[Detailed description of the invention] The present invention combines grain culms, specifically harvested grain culms using a binder, or harvested grain culms that have been harvested and threshed using a combine harvester, collects them in a predetermined amount, and then leaves them in the field. Regarding equipment.

Conventionally, this type of device for collecting and discharging bundled grain culms has a plurality of rods attached to the collecting culm shaft.
The rotation of this collecting culm axis caused the receiving rod to rotate diagonally, and the bundled grain culms on the receiving rod were discharged into the field. It is installed near the target field.

Therefore, if the length of the rod that rotates diagonally is made longer and the number of bundles of bundled grain culms is increased, the lower end of the rod will come into contact with the field surface or stump during rotation, causing breakage or bending.
This method was inefficient because it was limited by the length of the receiving rod, and by extension, the number of bundles of bundled grain culms.

The present invention was developed in response to these circumstances, and it solves the conventional problems with a simple configuration, and allows the collection culm axis to move upward when releasing the bundled grain culms. By rotating the holder provided in the holder, the length of the holder can be secured sufficiently,
At the same time, the aim is to increase the number of converging objects.

is provided. Reference numeral 23 denotes an ejection rotary arm having a refraction portion pivotally supported on the upper part of the case 12 and consisting of a horizontal rod portion 23a and an acute angle refraction rod portion 23b. is facing the side of the ratchet gear 13,
A pin 24 installed on the plate surface of the ratchet gear 13 is brought into contact with this bending rod portion 23b.

A shaft cylinder 25 is provided at the end of the horizontal rod part 23a of the discharge rotation arm 23 and is perpendicular to the horizontal rod part 23a. A plurality of bundled grain culm receiving rods 27 are rotatably inserted into the culm collection shaft 26 and are arranged at regular intervals, perpendicular to the axis of the culm collecting shaft 26 and always keeping parallel to the horizontal rod portion 23a. It is provided. One end of a short collecting shaft rotating arm 28 is fixed to the collecting shaft 26 diagonally downward on the outside of the main body A, and the other end of this collecting shaft rotating arm 28 and the case 12 are connected in a dogleg shape with a connecting rod 29.

30 is a stopper provided on the case 12, and the lower edge of the connecting rod 29 comes into contact with this stopper 30;
Due to the configuration of the collecting culm shaft rotating arm 28 connected to the end rod 29 in a dogleg shape, and the structure in which the end of the collecting culm shaft rotating arm 26 is fixed to the collecting culm shaft 26, the horizontal rod portion of the discharge rotating arm 23 is The rod 23a is held as shown in FIG.

In the figure, 31 indicates the horizontal rod portion 2 of the discharge rotation arm 23.
In order to urge the end 3a downward, in detail, the springs 32 and 33 act to press the connecting rod 29 against the stopper 30, and the springs 32 and 33 hold the bundled grain culm in the convergence device 4 and serve as guides when releasing it. Guide, 34,

0 and the sensing arm 18.

Next, to explain the action, the binder body A
The loose grain culm harvested and transported by the grain culm conveyor 2 is sequentially sent to the sensing door 9, and the needle 10 is actuated by the detection signal from the sensing door 9. The grain culms are bundled in a fixed amount and sent to the bundler 4 by the discharge arm 8.

When the needle 10 starts the tying operation, this movement causes the sensing arm 1 to move due to the action of the spring 20.
8 follows in the left direction in FIG. At this time, the feed pawl 22 of the rotating arm 17 is idle. Then, as the needle 10 returns to its old position after finishing the lacing, the sensing arm 18 and the rotating arm 17 resist the elasticity of the spring 20 and return to their original position. At this time,
The feed pawl 22 rotates the ratchet gear 13 clockwise by a predetermined angle. The ratchet gear 13 does not rotate in reverse due to the action of a reverse rotation prevention pawl 16.

When this operation is repeated several times, the pin 24 provided on the ratchet gear 13 pushes the bending rod portion 23b of the ejection rotation arm 23, and the ejection rotation arm 23 is shown by the imaginary line in FIG. position and move the culm collecting shaft 26 upward. With this displacement, the collecting rod rotation arm 28 and the connecting rod 29 become almost linear, and the receiving rod 27, which is attached to the collecting shaft 26 so as to form an acute angle with the collecting shaft rotating arm 28, Displaced diagonally as shown in the figure, and
There is a considerable distance between the lower end of this receiving rod 27 and the field.

Then, all the bundled grain culms on the receiving rod 27 are released,
At the same time, when the pin 24 of the ratchet gear 13 passes through the end of the bending rod portion 23b and the two become unrelated, the action of the spring 31 causes the discharge rotation arm 23, the collecting shaft 26,
The receiving rod 27, the collecting culm shaft rotating arm 28, and the connecting rod 29 return to the position shown by the solid line in FIG. 3, and assume the focusing posture again. In this embodiment, a binder has been described, but the present invention is not particularly limited to the embodiment as it can be used as it is for converging and discharging bundled culms of a combine harvester.

As described above, according to the present invention, when a set number of bundles of bundled grain culms are housed in the collecting device, the culm collecting shaft rotates while rising, and the receiving rod attached to the culm shaft rotates diagonally. The tied grain culms can be released into the field by moving. Furthermore, the support point of the rod by the collecting culm shaft is
Because the rod moves upwards when released, even if a longer rod is used than before, the end of the rod will not come into contact with the field or stump and be damaged during release. Due to this action, it is possible to increase the number of bundled grain culms and improve the efficiency of bundling and leaving, which has great practical effects.
