Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for concentrating bound grain culms in a binder.

[Conventional technology and its issues]

Bundled grain culms are bundled and the bundled grain culms are left in the field all at once, reducing the labor involved in post-harvest processing.
A binder designed to improve workability has already been proposed, but this type of device, like the conventional dropper device, when a bundled grain pressure greater than the set weight is applied to the discharge rod, Since the system utilizes the elasticity of elastic members such as springs to release the ejection rod and leave the group of bundled grain culms in the field, the weight of the grain culms themselves and changes in the length of the grain culms There is a problem in that the number of bundled grain culm bundles that are collected in the collection device varies depending on the size of the grain, the size of the weight depending on whether it contains moisture or not, and the impact force applied to the binder body during operation. .

As a means to solve these problems, a stem culm processing device equipped with a binding device has been proposed, for example, as disclosed in Japanese Patent Application Laid-Open No. 56-39714. This device can solve the problems of the prior art by counting and concentrating the bundled grain culms and releasing them for each set number of bundles, but it does not require a mechanism for changing the number of bundled grain culms or a mechanism for changing the number of bundles. The culm counting mechanism is complicated, and there are some inconveniences such as the mechanical unreasonableness of the device when used under adverse conditions.

The purpose of the present invention has been made in response to these circumstances, and it uses a simple configuration and rational means to eliminate the problems of the prior art, and to eliminate the action of releasing bundled grain culms by opening and closing the release rod. It is an object of the present invention to provide a binder which uses a setting signal for the number of convergent bundles and which can accurately discharge the number of bundles without variation in the number of bundles to be emitted using a simple structure.

〔Example〕

To explain the embodiment of the present invention with reference to the drawings, A
is a binder body, and the binder body A includes a grain culm raising device 1, a grain culm conveyor 2, a grain culm binding device 3,
It is composed of a bundled grain culm concentrator 4, a driving engine 5, a driving wheel 6, an operating handle 7, a discharge arm 8, and the like.

In the present invention, in the binder body A configured as described above, a bundled grain culm carrier 9 is successively provided at the end of the conveyance line of the grain culm carrier 2,
This bundled grain culm conveyor 9 is made to face the arc-shaped guide rod 10 provided on the binder main body A, and the bundled grain culm concentrating device Let yourself be guided by 4.

As is clear from FIG. 3, the bound grain culm conveyor 9 is composed of an endless belt 11 with protrusions, and this endless belt 11 is connected to a pulley 12 fixed to the terminal shaft of the grain culm conveyor 2, and a binder. It is flexibly suspended between a pulley 13 that is pivotally supported by the main body A. Reference numeral 14 denotes a housing provided on the upper part of the bundled grain culm transporter 9, and the housing 14 has a housing projecting forward above the bundled grain culm transporter 9 and across the bundled grain culm transport line. A midway portion of the sensing lever 15 is fixed by a shaft 16.
This sensing lever 15 is rotated in contact with the bundled grain culm passing while being supported between the bundled grain culm conveyor 9 and the guide rod 10, and the inner end of the sensing lever 15 and the above-mentioned A spring 16a is elastically provided between the sensing lever 14 and the housing 14 to bias the protruding end of the sensing lever 15 to the left in FIG. Reference numeral 17 in the figure is a power adjustment screw for adjusting the amount of rotational biasing of the sensing lever 15.

The rotation stroke of the sensing lever 15 is adjusted by the adjustment screw 17 to adjust the number of bundles of bundled grain culms to pass through, as will be described later. 18
is freely supported on the shaft 16, and
A ratchet wheel is provided above the sensing lever 15, and a feed pawl 20 whose back side is pressed by a spring 19 on the sensing lever 15 is removably engaged with the ratchet wheel 18. A back side of the ratchet wheel 18 is similarly pressed by a spring 21, and a reversal prevention pawl 22, which is pivotally supported on the housing 14, is engaged in a detachable manner.

Reference numeral 23 denotes an interlocking arm whose middle part is pivotally supported by the housing 14, one end facing the periphery of the ratchet wheel 18, and a hook 24 formed on the rear edge of the other end. A pin 25 implanted on the periphery of the ratchet wheel 18 comes into contact with the front edge of one end of the ratchet wheel 18, so that it can be rotated. Then, the end of the interlocking arm 23 on the side of the ratchet wheel 18 is
A spiral spring 26 for biasing forward (upward in the paper) connects the interlocking arm 23 and the housing 14.
A bullet is placed between them.

Further, reference numeral 27 denotes a discharge rod shaft which is vertically supported by the housing 14 near the other end of the interlocking arm 23 and provided behind the conveyance surface of the bundled grain culm conveyor 9. The shaft 27 has a lower end inclined in the advancing direction of the binder main body A and an upper end inclined in the opposite direction. And this ejection rod shaft 27
More specifically, a stopper 2 is attached to the upper part of the housing 14 and is detachably connected to a hook portion 24 formed on the rear side of the outer end of the interlocking arm 23.
Furthermore, the bases of a plurality of discharge rods 29 are fixed at appropriate intervals in the vertical direction of the discharge rod shaft 27 exposed downward from the housing 14. , a side guide 30 of the bundled grain culm that extends to the side of the binder main body A and has the tip of the discharge rod 29 provided in the convergence device 4;
It intersects with the rear end of the grain culm in a plane to prevent the bundled grain culm from being released inadvertently.

Further, as is clear from FIG. 3, the ejection rod 29 has an axis such that the outer end of the ejection rod 29 is slightly inclined rearward with respect to the axis perpendicular to the traveling direction of the binder body A when viewed from a plane. 27, the bundled grain culm released laterally from the bundled grain culm conveyor 9 is guided outward along this slope, and the subsequent bundled grain culm can be introduced smoothly. .

Further, as is clear from FIGS. 1, 2, and 3, the height of the discharge rod shaft 27 is at least between the step between the end of the conveyance surface of the bundled grain culm conveyor 9 and the base of the discharge rod 29.
A guiding plate 31 is provided which is approximately at the same height as the culm and is inclined backward toward the outside. so that the tip part is smoothly supported by leaning against the discharge rod 29 via the guide plate 31, and by utilizing the planar step difference between the conveying surface of the bundled grain culm conveyor 9 and the mounting position of the discharge rod 29, This allows the tied grain culms to be stored effectively.

As is clear from the figure, the discharge rod 29 is formed of a band plate made of an elastic material, and the plate surface is
The ejection rod axis 27 is perpendicular to the axis of the ejection rod axis 27.
The bundled grain culm is supported by the thick plate surface of the discharge rod 29. The reason for this is that when the ejection rod shaft 27 rotates during ejection, and the ejection rod 29 moves to the position of the imaginary line as shown in FIG. may move diagonally downward, and the tip of the lowest discharge rod 29 may come close to the field. Therefore, even if this discharge rod 29 comes into contact with the field or a stump, the virtual As shown by the line,
The discharge rod 29 bends upward or downward to relax and absorb the shock, thereby preventing bending damage to the discharge rod 29 and eliminating the possibility of the unattended bundled grain culm being carried away.

In this embodiment, all the ejection rods are formed of strips made of elastic material, but the lower ejection rods are made of elastic material, and the upper ejection rods are made of non-elastic round plates. It may also be formed with a stick or the like. In the figure, numeral 33 is a return spring for the release rod 29.

[Explanation of action]

Next, to explain the focusing and releasing action, the loose grain culm cut and conveyed by the binder main body A is moved between the grain culm conveying body 2 and the guide rod 10.
The grains are bundled by the action of the grain culm binding device 3, which is known in the art. As is clear from Fig. 3, the bundled grain culm bound in this way
The grain culms are conveyed rightward in the figure by the grain culm conveyor 9 which is subsequently suspended horizontally from the grain culm conveyor 2 of the main body, but on the way, the bundled grain culms move the sensing lever 15 due to the elasticity of the spring 16a. When the sensing lever 15 is pushed and rotated by a certain angle against the pressure and passes, the sensing lever 15 returns to its original state by the action of the spring 16.

Due to the fixed angle rotation return action of the sensing lever 15, the ratchet wheel 1 is moved by the action of the feed pawl 20.
8 is rotated by a certain angle, and the bundled grain culms that have passed are collected and supported between the discharge rod 29 and the root support 32 via the guide plate 31. By repeating this operation several times, a predetermined number of bundled grain culms are collected in the collection device 4, and the pin 25 installed in the ratchet wheel 18 is moved to the interlocking arm 2.
3 is pushed and rotated toward the rear (downward in the paper of the third drawing) to release the engagement between the hook 24 provided at the other end of the interlocking arm 23 and the stopper 28, and the pressure is applied to the discharge rod 29. Due to the load pressure of the bundled grain culms,
The release rod 29 rotates backward about the release rod shaft 27 against the elasticity of the return spring 33, and the bundled grain culm group is
They are forced to leave the roots in the field first. When this leaving is completed, the ejection rod 29 immediately returns to its old state due to the action of the return spring 33, and the tip of the stopper 28 engages with the hook portion 24 of the interlocking arm 23 again.
Adopt a supporting posture of the bound grain culm. Such operations are repeated.

[Effect of idea]

As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) Like a device that releases the ejecting rod by the weight of a group of bundled grain culms, the movement of the bundled grain culms, vibration of the binder body due to irregularities in the field, and changes in weight due to the properties of grain culms, length, etc. It goes without saying that the number of bundles less than or greater than the set weight will not be released, the set number of bundles will be reliably released and collected, and the post-processing process will be smoother. (b) A sensing lever that rotates and returns to the set angle by the bundled grain culms being conveyed, a ratchet wheel that rotates in one direction at the set angle by rotation of this sensing lever, and a pin installed in this ratchet wheel. The number of focused bundles is determined by the 360° concomitant rotation of the sensor lever, and the amount of rotation of the sensing lever, that is, the number of focused bundles can be arbitrarily increased or decreased by adjusting the protrusion and retraction of the adjustment screw that the sensing lever touches. Since the structure is simple, there is no error in operation even under adverse conditions in the field.

(c) Since the interlocking arm interlocked with the pin installed in the ratchet wheel releases the binding grain culm restraint of the discharge rod, it is possible to accurately collect and release the set number of bundles, and It is possible to improve the culm transportation, focusing, and release efficiency.
