Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a reaping and tying machine with a collection device on which a bunch of stems and culms that have been cut and tied can be placed.

[Conventional technology]

As this type of reaping and binding machine with a collection device, as disclosed in Japanese Patent Application Laid-open No. 124527/1983,
At the front of the fuselage, there is a pulling device that causes the planted stem culm,
A reaping device that reaps the raised stem culms and a binding device that ties the cut stem culms in a vertical position are installed, and behind these devices, a bundle of stem culms is lifted in a sideways position and placed in a horizontal position in a collection section located below the rear. A device is known that is equipped with a lifting and conveying device for discharging.

[Problem that the invention seeks to solve]

By the way, in the above-mentioned reaping and tying machine with a collection device, the stem culm bundle released from the tying device is lifted by the lifting and conveying device and immediately discharged to the collection section. There were cases where the stem and culm bundles were not aligned and were prone to collapse, reducing the load capacity.

An object of the present invention is to enable a specified amount of stem and culm bundles to be stacked on the collection unit in an orderly manner by enabling the lifted and transported stem and culm bundles to be discharged to the collection unit in a stable posture.

[Means for solving problems]

The characteristic configuration of the present invention includes a pulling device for causing planted stem culms in the front part of the machine body, a reaping device for reaping the raised stem culms, a binding device for binding the cut stem culms, and a tied device. In a reaping and tying machine equipped with a collection device that is equipped with a lifting and conveying device that lifts the stem culm bundle in a sideways posture and discharges it to a collecting section located below the rear, the stalk culm bundle immediately after being released from the lifting and conveying device is once placed in a sideways posture. A receiving mechanism is provided that receives and supports the stem culm bundle and then drops and releases it toward the collection section, and this receiving mechanism includes a backward cantilever-shaped receiving tool that widely receives and places the stem culm bundle in the culm length direction; It consists of a fixed guide that broadly locks the stem culm bundle placed on this holding device from the rear upper side in the culm length direction, and the holding device is placed in a stem culm bundle holding action posture that is inclined slightly backward and downward. The mechanism is configured to be able to freely switch between the discharge position and the discharge position that swings greatly.The functions and effects are as follows.

[Effect]

According to the above configuration, the stem culm bundle lifted by the lifting and conveying device is once received in a horizontal position on the receiving device, but at this time, since the receiving device is tilted slightly backward, the stem culm bundle is under its own weight. It slides down toward the rear free end of the catch and is supported by a fixed guide that locks from above. For this reason, the stem culm bundle assumes a fixed sideways posture by being placed and supported by the receiver and fixed guide that act broadly in the culm direction. Thereafter, as the receiving tool swings downward to open, the stem culm bundle falls onto the collecting section in a predetermined sideways posture.

〔Effect of the invention〕

Therefore, according to the present invention, after the stem culm bundle is lifted by the lifting and conveying device until it is released to the collecting section, the holding device and the fixed guide provide a posture correcting action to the stem culm bundle, so that the stem culm bundle has a desired sideways posture. After stabilizing,
It has become possible to discharge the stem and culm bundles onto the collecting section and stack them up in an orderly manner, and as a result, it has become possible to fully utilize the top of the collecting section and to load and collect a large amount of stem and culm bundles in a good manner.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in Figures 1 and 2, a reaping pre-processing unit A of the same type as a combine harvester is installed at the front of a traveling machine based on a combine harvester, and a binding device B is installed at the rear of the unit. And control section 1
A lifting and conveying device C is mounted on the left side, and a collecting section D is mounted behind it to constitute a reaping and tying machine with a collecting device.

The reaping pre-processing section A includes a raising device 2 for raising a planted grain culm, which is a type of stalk culm, a pair of puckers 3, 3 for raking the raised grain culm to the center;
A reaping device 4 that reaps the raked grain culms, and
It is composed of a vertical conveyance device 5, etc., which conveys the harvested grain culms backward and upward while gradually turning them sideways. The vertical conveyance device 5 consists of an ear-end locking conveyance device 5A that locks and conveys the tips of grain culms, and a stalk-clamping conveyance device 5B that conveys grain culms while clamping them. The culm is conveyed upward while lying on its side, and its stem head is sent to belts 6, 6 with protrusions for lifting the stem head arranged at the left end of the machine body. A stock removal rod 7 is provided extending from the machine body to the starting end of the protruding belts 6, 6 for smooth stock feeding.

As shown in FIGS. 3 and 4, the protruding belts 6, 6 are arranged side by side in pairs on the left and right, and direct the base of the sent stem culm Sa to the lower route. While holding it, transport it backwards and upwards. At the end of the conveyance path of the protruded belts 6, 6 and before the grass collection space of the binding device B, in other words, near the end of the action of the tip trajectory of the packer arm 8 of the binding device B, there is a stock of grain culm Sa. A cutting device 9 is provided for trimming the base ends. This cutting device 9 has a fifth
As shown in the figure, a long hole 10a is formed in a long piece of an L-shaped link 10 that is rotatable around an axis _P1 ,
The pin 1 at the tip of the crank arm 11 is inserted into the elongated hole 10a.
1a, and insert the engaging portion 1 at the tip of the short piece.
0b is cut out, and the pin 12a of the movable blade 12 is engaged with the engaging portion 10b. According to this structure, when the crank arm 11 rotates, the link 10 swings in conjunction with the rotation, and the movable blade 12 engaged with the short piece slides relative to the fixed blade 13 to perform a cutting action.

A binding device B is disposed behind the ends of the belts 6, 6 with projections, and the grain culms Sa that have been sent in a sideways posture are scooped in by the packer arm 8, converged and tied at the same time, and the grain culms are bundled. S is discharged rearward using the discharge door 14. Incidentally, the end portions of the protruded belts 6, 6 and the tip locus of the packer arm 8 partially overlap in side view so that the grain culm can be transferred smoothly. The discharge door 1
4 is a blade-like member that rotates around the left and right horizontal axis _P2 , and its operating portion is connected to the lifting and conveying device C.
It faces the grain culm supply port 15. This discharge door 14 is designed to be driven to rotate at all times during the operation of the bundling device B, but immediately after the grain culm bundle S is discharged, it is temporarily stopped in front of the grain culm supply port 15 and the supply port 15 is opened. Clogged and fed grain culm bundle S
The delivery to the lifting and conveying device C can be carried out reliably. In other words, since the lifting and conveying device C is of a clamping conveyance type and is oriented upward, if the supplied grain culm bundle S hits an undesired place and bounces back, or if the grain is not penetrated properly, the delivery will be delayed. There is a risk that it will fail and fall down from the grain culm supply port 15. Therefore, after the grain culm bundle is released, the discharge door 14 closes the grain culm supply port 15 for a certain period of time to help ensure that the grain culm bundle S is held.

As already shown in FIG. 3, the lifting and conveying device C is provided with a chain case 16 that is high upwardly and slightly tilted backwards, and has a drive sprocket 17 at the lower end and a drive sprocket 17 at the upper end that are pivotally supported within the chain case 16. A chain 19 with protrusions is wound around the driven sprocket 18, and the chain case 1
A clamping rail 20 is provided along a chain 19 with protrusions exposed from 6 to the front side.
Further, the shaft 21 of the driven sprocket 18 is extended outside the chain case 16, and a rotary tool 22 for raising and discharging grain culms is attached to the end on the ear tip side.
A large-diameter rotating shaft 23 that is driven to rotate integrally with the shaft 21 is fitted on the stock side. Further, at the rear of the upper end of the lifting and conveying device C, in other words, at the rear of the terminal end, there is provided a receiving section E that once receives the grain culm bundle S discharged from the device C in a sideways posture and then releases it all at once to the collection section D. There is.

Therefore, the grain culm bundle S supplied to the grain culm supply port 15
is conveyed upward and rearward in a sideways posture while being held by the chain 19 with protrusions and the holding rail 20, and when it reaches the end, it climbs over the rotary tool 22 and the rotating shaft 23 and falls once onto the receiving mechanism E, where it falls sideways. After assuming the posture, it falls and is released into the collection section D below.
In addition, when the grain culm bundle S reaches the terminal end of the lifting and conveying device C, the rotary tool 22 scrapes up the drooping tips of the grain culm bundle S, adjusts the release posture of the grain culm bundle S, and allows the grain culm bundle S to fall into the receiving part E. This is to prevent the sideways posture of the grain culm bundle S from being disturbed. In addition, when the grain culm bundle S falls to the receiving mechanism E, if several grain culms separated from the grain culm bundle S remain on the conveyance path and are caught in the following grain culm bundle, the grain culm bundle When S is dropped and released from the receiving mechanism E, this causes a large disturbance in the release posture.
Therefore, by providing the rotating shaft 23 on the stock side,
When the grain culm bundle S falls and is released into the receiving mechanism E, the grain culms that are separated are caught on the rotating shaft 23, and the rotational force of the rotating shaft 23 and the weight and elasticity of the grain culm bundle S are transmitted through friction. The restoring force pulls it upward to assist in getting out of the conveyance path and prevent it from getting caught in the following grain culm bundle S.

The receiving mechanism E includes a rearward-facing cantilever-shaped receiving member 24 that is vertically swingable around a horizontal axis _P3 at the rear end of the lifting and conveying device C, and a backward-facing piece that bypasses the upper part of the lifting and conveying device C. A holding-like fixed guide 33 is provided. Then, the receiving tool 24
is made of a wide board in the direction of the culm of the stem culm bundle, and is swingable to switch between a slightly downwardly slanted stem culm bundle receiving position and a downwardly swinging discharge position. Further, the fixed guide 33 is a stem culm bundle S.
Two rods are provided on the left and right so that they act widely on the plant base side and the ear tip side, and the rear ends of each extend close to the rear end of the receiving tool 24 in the stem culm receiving position, and the upper end of the receiving tool 24 is The stem and culm bundle S, which is released and slipped backward, is locked from behind by a fixed guide 33 and stably held in a predetermined sideways posture.

Further, the receiving device 24 is configured to automatically switch between the stem culm bundle receiving posture and the releasing posture, and the structure thereof will be described below. That is, an L-shaped link 25 is rotatably attached to the side wall of the lifting and conveying device C, a rod 26 is pivotally connected to the tip of one piece, and a pin 25a is formed at the tip of the other piece to receive the link. It is brought into contact with the tip of an arc-shaped link 27 that swings integrally with the stop 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 able to swing up and down, and its tip protrudes onto the conveyance path of the lifting and conveying device C, and the lower end of the rod 26 is pivotally supported. As a result, the L-shaped link 25 rotates in conjunction with the upward swinging of the contact link 28, and the abutment between the contact pin 25a and the arc-shaped link 27 is released, that is, the lock of the catch 24 is released. It is about to be lifted. In short, in a state where the grain bundle S is received on the receiving tool 24, when the following grain culm bundle S contacts the contact link 28 on the lifting and conveying path and swings upward, the receiving tool 24 The lock is released and the grain bundle S on top of it slides down from the receiver 24 under its own weight (see Figure 6). Incidentally, after the grain culm bundle S is dropped and released, the L-shaped link 25 and the contact link 28 are returned to the initial state by the spring 29, and
The catch 24 is also returned to its horizontal position by the spring 30 and returns to its original locked state.

The recovery section D has an axis at the rear end so that the loaded grain culm bundles S in a sideways posture can be lowered to the ground all at once.
It is configured so that it can be dumped around _P4 . 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 S can smoothly slide down to the ground.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
