Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a mowing and tying machine with a collecting device capable of placing a fixed amount of mowing and bundling culm bundles.

[Conventional technology]

Japanese Patent Laid-Open No. 51-124 discloses a cutting and binding machine with a collecting device of this type.
As disclosed in Japanese Laid-Open Patent Publication No. 527, in the front of the fuselage, a raising device that causes planted grain culms, a reaping device that mows the grain culms that have been caused, and a binding device that binds the mowed grain culms in a vertical posture. In addition to the above, it is known that a lifting / conveying device for raising the grain culm bundle in a horizontal position and lifting the grain culm in a horizontal position and discharging it in a horizontal position is provided behind them.

[Problems to be solved by the invention]

By the way, since the above-mentioned harvesting and binding machine with a collecting device binds the harvested grain culms in a vertical posture, the heavy tips are on top and unstable, and binding disorder is likely to occur. Moreover, it is necessary to change the vertical posture to the horizontal posture when lifting the grain culm bundle discharged from the bundling device and sending it to the transport device, but it is difficult to bend because the grain culm is a bundle and the posture is changed. It is difficult for the grain to be picked up, and therefore the transport posture and the discharge posture are easily disturbed after changing the posture, and the grain culm bundles placed on the collection section are easily misaligned and the loadable capacity decreases. There was a risk of causing the situation.

Further, in the conventional one, when the posture of the grain culm bundle after bundling is changed sideways, the root side of the grain culm bundle is raised so that the tip side is located outside. There is a possibility that the part may come into contact with planted culms, etc. on the uncut side,
Therefore, there is a risk of shedding.

The present invention has been made in view of the above circumstances, and when binding the harvested grain culms, it suppresses the disorder of the grain culm bundles, and makes it possible to properly align the transporting posture and the discharging posture so that the grain culms are To make it possible to stack the bundle in a stable state on the collection unit and to sufficiently load it to the specified amount. Also, when binding and transporting the bundle, there is a problem that the tip part of the grain stem contacts the uncut grain stem etc. (EN) Provided is a cutting and binding machine with a recovery device that can be suppressed.

[Means for solving problems]

In order to achieve the above-mentioned object, the harvesting and binding machine with a collecting device according to the present invention has a raising device for causing planted grain culms in the front part of the machine body, a reaping device for reaping the raised grain culms, and the reaped The grain culm is provided with a vertical transport device that raises and conveys the grain culvert in a horizontal position so that the strainer is located on the outer side of the machine. A binding device that binds the root side of the grain culm in a posture, and a lifting conveyance that lifts the bundle of grain culms in a state of lying down while holding the middle part of the grain and releases it to the collecting section at the lower rear. A device is provided as a characteristic configuration.

The operation and effect of this characteristic configuration are as follows.

[Action]

In other words, the culms that have been cut and plucked are placed sideways by the vertical transport device so that the root of the stock is located on the outer side of the fuselage, so that the tips are not located on the outer border of the fuselage. While being lifted and conveyed as described above, it is fed to the bundling device in a horizontally lying posture toward the rear of the vertical conveyance device. Then, the planter side of the sent grain culm in the sideways posture is bundled, and the bundled grain culm bundle is held in the sideways posture and lifted in the state of holding the middle part of the stem and released to the collecting section at the lower rear. It goes.

In short, before the grain culms are bundled and become difficult to bend, the vertical transport device conveys the grain culms to a horizontal position with the tip part smoothly and smoothly so that the tip portion is not located outside, and then the plant side is placed. It will unite.

[Effect of device]

As a result, by putting the grain culm whose tip side is heavy in the grain sideways to the posture, it is possible to bind the grain culm's stock in a stable state, and when the culm is laid down, the stock wa By changing the posture so that the tip is not located outside the side of the machine body, it is possible to avoid the problem that the tip part comes into contact with the uncut grain culm, etc. The occurrence of is suppressed. Then, since the grain culm bundle in the sideways posture released from the bundling device can be sent to the lifting and conveying device as it is without changing the posture, the grain culm bundle is lifted and conveyed in a state in which the disturbance of the posture is suppressed, and to the collecting unit in that posture. By discharging, the grain stack can be fully loaded up to the specified amount in the transporting posture and the placing posture in the collecting unit. Further, since the lifting / conveying device lifts and conveys while holding the middle part of the grain of the grain culm, it has an advantage that the structure is simple and compact as compared with the case where the lifting and conveying devices are arranged side by side. is there.

In addition, since the grain culms are lifted by the vertical conveying device and then bound, the binding position is at the upper side, so that there is an advantage that the binding device can be provided at the upper side to simplify the vicinity of the ground. That is, when the binding device is close to the ground, the machine body tends to be laterally bulky in order to secure the installation space, and therefore the bulky part comes into contact with the planted culm when working in the middle of the field. It is desirable to make the aircraft near the ground as compact as possible. The present invention fully meets this need.

〔Example〕

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

As shown in FIG. 1 and FIG. 2, a cutting pretreatment unit (A) of the same type as the combine is attached to the front of the combine-based traveling machine body, and a binding device (B) is provided at the rear of the combine. Further, a lifting and conveying device (C) is mounted on the rear side of the control section (1) and on the left side of the control section (1), and a collecting section (D) is mounted on the rear side of the lifting and conveying apparatus to form a harvesting and binding machine with a collecting device.

The pre-cutting processing section (A) is a raising device (2) that causes planted grain culms, a pair of packers (3) and (3) that scrapes the culmed grain culms to the center, and the raked grain culms. It is composed of a mowing device (4) and a vertical conveying device (5) which gradually lays down the mowed grain culverts to a rearward and upward direction, and the like. The vertical transfer device (5) is
Ear tip locking / conveying device that locks and conveys the tips of grain culms (5
A) and a stock holding device (5B) for holding and holding the stock while holding the grain culm in a vertical position as shown in FIGS. 1 to 4, The stock of the culm is located on the outer side of the machine and is conveyed to the upper side in a sideways posture. The stock is raised to the belt with protrusions (6) and (6) for lifting the stock located at the left end of the machine. send. A stock withdrawal rod (7) for smoothing the feeding of the stock is provided from the machine body to the start end sides of the belts (6) and (6) with protrusions.

As shown in FIG. 3 and FIG. 4, the belts (6) and (6) with protrusions are arranged side by side in a pair, and the plant origin of the grain culm sent to the lower side is placed on the lower side. Hold it along the route and transport it backward and upward. This belt with protrusions (6),
At the end of the transport path of (6) and before the grass collecting space of the binding device (B), in other words, in the vicinity of the action end portion of the tip locus of the packer arm (8) of the binding device (B), the grain culm is provided. A cutting device (9) for cutting and aligning the root ends of the plants is provided. As shown in FIG. 5, this cutting device (9) forms a long hole (10a) in a long piece portion of an L-shaped link (10) which is rotatable around a shaft core (P ₁ ). Crank arm (1
1) Insert the pin (11a) at the tip, cut out the engaging part (10b) at the tip of the short piece, and engage the pin (12a) of the movable blade (12) with the engaging part (10b). Configured. According to this structure, when the crank arm (11) rotates, the link (10) swings in conjunction with it, and the movable blade (12) engaged with the short piece slides on the fixed blade (13). The cutting action works.

A bundling device (B) is arranged behind the ends of the belts (6) with protrusions (6), and at the same time, the fed grain culms in a sideways posture are scraped by the packer arm (8) to be bundled. The roots of the stock are bound together, and the grain culm bundle is discharged rearward using the discharge door (14). The belt with protrusions (6),
(6) and the trailing end of the stock carrier holding and conveying device (5B) and the trail of the tip of the packer arm (8) are partially wrapped in a side view so that the grains can be delivered and received smoothly. The discharge door (14) is a blade-like member that rotates around the left and right horizontal axis (P ₂ ), and its working portion faces the grain culm supply port (15) of the lifting and conveying device (C). There is. The discharge door (14) is constantly driven to rotate during operation of the binding device (B), but immediately after the discharge of the grain culm bundle, the discharge door (14) is temporarily stopped before the grain culm supply port (15). The supply port (1
5) is closed so that the supplied grain culm bundle can be reliably delivered to the lifting and conveying device (C). In other words, since the lifting / conveying device (C) is a holding and conveying system and is directed upward, if the supplied grain culm bounces off at an involuntary place, or if it does not bite well, it is delivered. There is a risk of failure and falling down from the grain culm supply port (15). Therefore, after the grain bunches are discharged, the discharge door (14) closes the grain culm supply port (15) for a certain period of time to help the grain bunches be securely held.

The lifting / conveying device (C) is provided with a chain case (16) in a posture in which the chain case (16) is high upward and slightly inclined rearward as already shown in FIG. A chain (19) with a protrusion is wound around the drive sprocket (17) and the driven sprocket (18) at the upper end, and the chain (19) with a protrusion is exposed from the chain case (16) to the front side. It is configured with a holding rail (20). Further, the shaft (21) of the driven sprocket (18) is extended to the outside of the chain case (16), and a rotary tool (22) for scraping and raising the grain culm is attached to the tip end side of the chain case (16). A large-diameter rotary shaft (23), which is driven to rotate integrally with the shaft (21), is fitted in the shaft. Further, at the rear of the upper end of the lifting and conveying device (C), in other words, at the rear of the end, the grain culm bundle discharged from the device (C) is laid down sideways and temporarily received, and then discharged to the collecting part (D) at once. A stop (E) is provided.

Therefore, the grain culm bundle supplied to the grain culm supply port (15) is
As shown in FIG. 4 to FIG. 4, the lower the carrier is, the more the root of the grain culm is located laterally outside of the machine body and the upper part of the machine is conveyed upward, and the chain with protrusions (19) and the holding rail ( While being held by 20), it is conveyed to the upper rear in a sideways posture, and when it reaches the end thereof, it crosses over the rotating tool (22) and the rotary shaft (23) and once falls to the receiving portion (E) to become a sideways posture. After that, it is dropped and discharged to the collecting section (D) below.
In addition, the rotating tool (22) scrapes the ears that droop when the grain culm bundle reaches the end of the lifting and conveying device (C), and adjusts the release posture of the grain culm bundle to the receiving portion (E). This is to prevent the falling posture of the grain culm from falling sideways. Also, when several grain culms separated from the grain culm bundle remain in the transport path when the grain culm bundle falls to the receiving part (E) and is caught in the succeeding grain culm bundle, the grain culm bundle is received. Stop (E)
It may cause a large disturbance in the release posture when the product is released from the ground. Therefore, by installing the rotary shaft (23) on the stock side,
The grain culm scattered when the grain culm bundle falls and is discharged to the receiving part (E) is hooked on the rotating shaft (23), and the rotational force of the rotating shaft (23) transmitted through friction and the weight of the grain culm bundle. Also, the elastic restoring force assists in pulling upward by pulling it out of the conveying path, and prevents it from being caught in the succeeding grain culm bundle.

The receiving portion (E) is provided with a receiving plate (24) at the rear end of the lifting and conveying device (C) so that the receiving plate (24) can be vertically swung around the horizontal axis of the horizontal axis, and the receiving plate (24) is placed in a horizontal posture. A state in which the grain culm bundles that are locked and dropped from the lifting and conveying device (C) can be received, and a state in which the locks are released to allow the receiving plate (24) to swing up and down, in other words, a grain culm bundle. Weighing plate (2
4) oscillates downward and automatically switches to a state in which a drop of grain culms can be discharged. More specifically, the L-shaped link (25) is rotatably pivotally attached to the side wall of the lifting and conveying device (C), and the rod (26) is pivotally connected to the tip of one of the pieces and hits the tip of the other piece. The pin (25a) is formed and is brought into contact with the tip end portion of the arcuate link (27) that swings integrally with the receiving plate (24). Further, a contact link (28) is pivotally attached to a side wall located below the L-shaped link (25) so as to be capable of swinging up and down, and a tip of the contact link (28) is lifted to be projected onto a transport path of a transport device (C) and the rod is The lower end of (26) is pivotally connected, whereby the L-shaped link (25) rotates in conjunction with the swinging of the contact link (28) upwards, and the hit pin (25a) and the arc-shaped link ( The contact of 27) is released, that is, the catch plate (24)
Is unlocked. In short, in the state in which the grain culm bundle is received on the receiving plate (24), the succeeding grain culm bundle is brought into contact with the contact link (2
When it comes into contact with 8) and swings upward, the lock of the catch plate (24) is released, and the grain culm bundles above it slide off from the catch plate (24) by its own weight (see FIG. 6).

After the drop of the grain culm is released, the L-shaped link (25) and the contact link (28) are returned to the initial state by the spring (29), and the receiving plate (24) is also moved by the spring (30). It is returned to the horizontal position and returns to the original locked state.

The collecting section (D) is configured to be capable of dumping around the rear end axis (P ₃ ) so that the stacked grain culm bundles in the lying-down posture can be collectively lowered onto the ground. Moreover, when the collecting part (D) dumps, the rear side plate (31) falls down and becomes flush with the bottom plate (32), so that the grain culm bundle can be smoothly slid to the ground.
