Description

[Detailed description of the invention] [Industrial field of application] This invention provides a culm collecting section at the rear of a tying machine connected to a combine harvester, and collects a suitable number of bundled culms so that their tip sides lean against each other. This relates to a discarded culm processing device that enables discharge into the field in an upright position, that is, in a conical shape with the root of the plant facing downward and the upper tip side close to each other.

[Conventional technology]

Conventional bundling devices attached to bundling machines are generally of the so-called weight balance type, which opens the bottom plate and discharges the culm bundles to the outside of the machine when a certain weight of waste culms has been collected.

[Problem that the invention attempts to solve]

Since the above-mentioned device operates based only on weight, the number of emitted bundles often differs due to factors such as changes in the length of the culm or the volume of the bundled culm, resulting in the inconvenience that it is not constant. Furthermore, the released culm bundle is usually in a state of lying on its side, and it is difficult to realize a mechanism to make it into an upright position, so it has not been put into practical use at present.

The present invention provides a waste culm processing device devised in view of the above, and is capable of always discharging a predetermined number of waste culms without being affected by the size or weight of the bundle. The purpose of this invention is to obtain a release mechanism that can be freely set in advance and that allows the grain culms to stand up in a conical shape with their ear tips leaning against each other in the field.

[Means for solving problems]

In order to achieve the above object, a knot part and a bundle release arm are provided at the corresponding part of the root side of the grain culm, and a door, a patcher, and a needle are installed across the binding passage, and a counting device is provided to count the number of times the door is opened and closed. a count value selector device, an opening/closing mechanism that activates a focusing plate of the culm in accordance with the output of the selector device, and a reset mechanism that responds when the focusing plate returns;
Provided at the tip side corresponding part of the focusing plate,
and a claw arm frame body that performs a gripping function for pinching the tips of a plurality of grain culm bundles and a raising and lowering operation, an opening/closing mechanism for the claw arm frame body, and an energized member for performing a return operation when the claw arm frame is raised and lowered. The present invention constitutes a culm processing device for a combine harvester characterized by comprising an elastic member.

[Effect]

According to this invention, the grain culms bound by the binding device of the combine harvester are transferred to the collecting plate by opening the door when being transferred to the exit side of the combine harvester.
A counting device, a selector device for the counted value, an opening/closing mechanism, and a reset mechanism enable a predetermined number of grain bundles to be released by opening the convergence plate, and after discharge, the condensation plate can be returned to its original position. In addition, when releasing the grain culm bundles, a predetermined number of grain culms are transferred to the collection receiving plate by the claw arm holder, the opening/closing mechanism of the claw arm holder, and the elastic member that returns the claw arm holder. In order to clamp the tip side of the bundle and release the grain culm bundle, which becomes drooping except for the tip side, into the field by opening the collection receiving plate, the claw arm clamping body is rotated to hold the tip side. If the release is released, the grain culm bundles will stand in the field in an upright state with the root side spreading out and the ear sides leaning against each other. The above claw arm frame is
It will be returned to its original state by the elastic member.

As a result of the above, grain bundles are released from the combine into the field in predetermined numbers, but at that time, they stand in an upright position with the root side facing down and the upper ears leaning against each other. .

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing the entire combine harvester including the binding device. In front of the machine stand 1, a known reaping section consisting of a grain culm combing body 2, a weed splitting body 3, and a cutting blade 4 is constructed. The grains are transported to the threshing device 7 by the transporters 5 and 6 and threshed. It should be noted that the mechanisms related to the above-mentioned reaping section, conveyance body, threshing device, etc. are well known, and detailed explanations thereof will be omitted. Next, a culm chain 8 for transferring the removed culms is provided behind the threshing device, and the transferred culms are bound by a binding device 9. FIG. 2 shows an enlarged view of the main parts of the binding device.
The threshed grain culms conveyed by the culm discharge chain 8 are received through a bundling passage 10 and subjected to bundling processing.
In the part corresponding to the root side of the grain culm of the bundling device 9, there is provided a knot part consisting of a string holder 11 and a knotter bill 12, and a bundle release arm 13 at the top with a bundling passage 10 in between, and a door 14, a packer 15, and a needle 16 are provided. When a moderate pressure is applied to the door 14 by the exhaust culm, a power clutch (not shown) is activated.
is inserted, and the needle 16 is rotated. Reference numeral 20 designates a string hole bored at the tip of the needle 16.

Further, as shown in FIG. 3, the door 14 performs an opening/closing operation in the direction of arrow A with respect to the rotation center 14', and the sensor rod 22 is activated by the operation of the auxiliary rod 21 in response to the opening/closing operation. It swings as shown by arrow B to connect and disconnect the door sensor 23.

FIG. 4 shows an example of a counting device for counting the number of openings and closings of the door sensor 23 and a selector device for the counted value, and shows an example of a combination of a self-propelled return type stepping relay and a rotary selector. 2
4 is a power source, 25 is a main switch, 26 is a reset switch, 27 is a rotary selector, 28 is a solenoid for opening and closing the focusing plate, 29 is a solenoid for holding the tip of the culm, and 30 is a stepping relay.

The above configuration has a circuit function that activates the solenoids 28 and 29 when the input from the door sensor 23 matches the count value set in the rotary selector 27, and the set value of the rotary selector 27 can be changed arbitrarily. be.

Below the binding device 9 shown in FIG.
is rotatably mounted on a fulcrum 33, and one end of an electromagnetic rod 34 led out from the solenoid 28 is attached. A hook 36 that engages with a hook 35 provided at the tip of the lever arm 32 is attached to a fulcrum 37, and the fulcrum 37 further holds one end of a focusing plate 38. The other end of the focusing plate 38 is fitably held at the lower end of the outer casing 39. Furthermore, a reset sensor 4 is located halfway through the hook 36.
0 is equipped and set to operate when the hook 36 returns. In addition, 41 is a spring for returning the hook 31.

FIG. 5 is a front view illustrating the opening and closing operation of the claw arm frame 42 of the culm, FIG. 6 is a plan view of the same, and FIG. 7 is a side view of the same. A claw arm frame 42 is fixed to an arm 44 that is rotatable about a support shaft 43, and a solenoid 2 that pulls a wire 45.
The opening/closing drive is performed by the operation of 9. 46 is an arm return spring, and 47 is a claw return spring.

The present invention is mainly based on the above-mentioned configuration,
Now, the grain culm threshed by the threshing device 7 shown in FIG. , after cutting with the knife, the door 1 is released by the throwing action of the bundle releasing arm 13 which rotates later than the knot.
Released via 4. The opening and closing operations of the door 14 are sensed by the door sensor 23 and counted by the counting device as described above. now,
When the rotary selector 27 is set to "3" as shown in the fourth figure, the stepping relay 30 that responds to the opening/closing operation of the door sensor 23 sequentially moves its contacts until the door 14 is "opened" for the third time.
When the state is indicated, conduction is established to the selector side and the solenoids 28 and 29 are driven. In other words, the electromagnetic rod 34 moves in the direction of arrow C, and the lever arm 32 shown in FIG.
The hook 3 is engaged with the hook 35 by the tilting of the hook 3.
6 leaves. At the same time, the electromagnetic rod 4 of the solenoid 29
8 moves in the direction of arrow D and pulls the wire 45, and the claw arm frame 42 enters the "closed" state shown by the imaginary line in FIG. 5, and clamps the tip side of the culm.
This state is shown in FIG. 8, and as is clear from the figure, the focusing plate 38 that opens and closes is formed only on the root side of the culm, and the focusing plate 38, which opens and closes, is formed only on the root side of the culm. The two are separated by forming a rotating claw arm frame, which facilitates the falling operation of the culm.

When the focusing plate 38 opens due to the detachment of the hook 36, the culm, whose tip is still being held, responds to the movement of the arm 44, which rotates about the support shaft 43, due to the weight of the ejected culm. It falls and comes to a stop in a direction perpendicular to the ground. Next, when the focusing plate 38 is returned to its original state by the return spring 41, the hook 36 abuts against the reset sensor 40, and the counting device is reset.
When the solenoids 28 and 29 stop operating, the claw arm frame 42 is returned to the "open" state by the claw return spring 47, and the claw arm frame 42 is returned to the upright state by the action of the arm return spring 46. I will make you return. By repeating the above steps and sequentially tying and releasing the ejected culms, the ejected culms do not come apart even if the tip side is not tied with a string, for example, three bundles of tips can be formed as shown in the figure. They can maintain a standing posture in which they lean on each other.

The present invention relates to a waste culm processing device for a combine harvester having the above-described configuration and operation mode.If the rotary selector 27 is installed near the driver's seat of the combine harvester, the number of bundles released from the bundled culm during operation can be reduced. can be changed arbitrarily. Normally, in order to dry the culms in the sun, it is appropriate to drop and release three bundles at a time in an upright manner as shown in this example, and it is possible to easily maintain the upright state. Of course, more bundles may be made and dropped. In the above process, by adjusting the driving timing of the solenoids 28 and 29, a time lag may be created between the two so that the operation can be made smoother, if necessary. This allows for a wide variety of
Alternatively, it can be easily adapted to grains with different culm lengths.

[Effect of idea]

By applying this invention, changes in the length of the culm,
A constant number of ejected culms are always obtained without being affected by weight, and the culms stand up leaning against each other in the field, resulting in great advantages such as increased drying efficiency and subsequent processing efficiency. It has great practical effects.
