Description

[Detailed description of the invention] The present invention relates to a device for bundling harvested grain culms and empty grain culms after reaping and threshing into a fixed amount and tying them with strings. In order to prevent the grain from returning when the grain culm is fed in, a spring-biased shutter is installed in the grain culm passage in front of the door of the convergence section to resist the pressing force from the front of the grain culm flow. The shutter is provided so that it can be tilted and rotated only in the rear direction, and the shutter can be installed in a position adjustable in the front and rear directions of the grain culm passage, so that it can correspond to the size of the bundle in the convergence section. , this will be explained based on an example in which this is applied to a combine harvester.
1 shows a conventionally known self-propelled, self-removal type combine main body, and inside a cover case 2 provided at the rear thereof, there are provided an inclined guide deck plate 4, an empty grain culm chain 3 connected to a feed chain (not shown) of the combine, and an inclined guide deck plate 4.
A conventional method in which empty grain culms that are sent along the top of the guide deck plate 4 and 5 in a direction substantially perpendicular to the culm body are collected in appropriate amounts and then tied together so that they protrude rearward along the top of the guide deck plates 4 and 5. A binding device 6 is provided.

This binding device 6 includes a transmission case 7 with an L-shaped side surface, a bearing case 8 protruding from the upper side of the transmission case 7, and a knot shaft 9 pivotally supported within the bearing case 8.
a knot 10 attached to the tip of the transmission case 7;
It consists of an input shaft 11 supported parallel to the nodal shaft 9 at the lower side of the nozzle, a clutch shaft 12, and a converging portion 14 attached to the tip of the door shaft 13.
is equipped with a building 15 and a holder 16 driven by a nodal shaft 9, and the bearing case 8 has two release arms 17, 18, 1 at appropriate intervals in the axial direction.
9 is connected via a link 21, and the distal end of a crank 22 fitted on the end of the nodule shaft 9 is pivotally connected to the bracket 20, so that rotation of the nodule shaft 9 causes each ejection arm 1 to be
The tips of 7, 18, and 19 are configured to swing in the direction of the arrow along a locus shown by a two-dot chain line 23 in FIG.

The focusing section 14 includes a packer 24 and a needle 2.
5 and a door 26, and the input shaft 11 is constantly driven to rotate by power transmission from the power source of the combine harvester. The packer 24 has a base end connected to the transmission case 7 via a curved link 27, and a crank 28 fitted to the tip of the input shaft 11.
The tip of the needle 25 is pivoted so that the rotation of the input shaft 11 causes the tip of the needle 24 to swing in the direction of the arrow along the locus shown by the two-dot chain line 29 in FIG. Its proximal end is rotatably supported on the door shaft 13, and the distal end of a crank 30 fitted on the distal end of the clutch shaft 12 is pivotally connected, so that the rotation of the clutch shaft 12 causes the needle 2 to
5 moves upward toward the bill 15 at the knot 10, and binds both ends of a string (not shown) passed through the needle 25 with the bill 15, and The door 26 is fitted onto the door shaft 13 so as to protrude upward from between the guide deck plates 4 and 5.

A gear 32 that meshes with a gear 31 fitted on the input shaft 11 is rotatably fitted onto the clutch shaft 12 in the transmission case 7, and the clutch 3
3, the clutch 33 and the door shaft 13 are related to each other via a clutch interlocking mechanism 34, and when the door 26 attached to the door shaft 13 rotates rearward, the clutch 33 is moved by the action of the clutch interlocking mechanism 34. When the clutch shaft 13 engages with the idler gear 32, the clutch shaft 13 starts to rotate, and when the clutch shaft 13 rotates once, the clutch 33 and the idler gear 32 are connected by the clutch interlocking mechanism 34.
The rotation of the clutch shaft 12 is stopped when the clutch shaft 12 is automatically disengaged from the clutch shaft 1.
The chain 38 is transmitted from the sprocket 35 fitted on the clutch shaft 2 to the sprocket 37 of the intermediate shaft 36, and the chain 41 is transmitted from the sprocket 39 of the intermediate shaft 36 to the sprocket 40 on the connecting shaft 9, so that the clutch shaft 12 rotates once. At the same time, the knot shaft 9 rotates once and stops.

and 42 is a shutter that projects upward from the side or slot 43 of the guide deck plate 4 or 5 at an appropriate position in front of the door 26 of the focusing section 14;
A bracket 45 having a downward U-shaped cross section or the like and which rotatably supports the base end of the shutter 42 on a shaft 44 is fixed to the lower surface of the guide deck plate 4 or 5 with a screw 46, and one end of a torsion spring 47 loosely fitted onto the shaft 44. The shutter 42 is latched to the shutter 42 and the other end is latched to the bracket 45 to urge the shutter 42 into an upright position. Further, by attaching a locking pin 48 which can change the locking position of the other end of the torsion spring 47 to the side surface of the bracket 45, the spring biasing force applied to the shutter 42 can be freely adjusted. Then, the shutter 4 is moved against the force of the spring 47.
2 tips fall toward the rear along the grain culm flow direction (arrow A), and the height between the top surface of the guide deck plate 5 and the tip of the shutter 42 decreases toward the front side of the door 26. Configure.

Further, the mounting position of the bracket 45 of the shutter 42 is configured so that it can be changed as needed inside the front end trajectory 23 of the pack car 24 with respect to the front and back direction of the guide deck plate 5.

With this configuration, the empty grain culm sent from the empty grain culm chain 3 to both guide deck plates 4 and 5 is scraped by the rear surface of the packer 24 due to the swinging movement of the locus 29 of the packer 24 caused by the rotation of the input shaft 11. ,
The empty grain culm comes into contact with the front surface of the shutter 42, presses it backwards, and knocks down the shutter 42 against the force of the spring 47 (see the two-dot chain line in Figure 4), and when the empty grain culm climbs over the shutter 42, the shutter is released. 42 is torsion spring 4
While standing up due to the force 7, the empty grain culm that has climbed over is obstructed by the rear surface of the shutter 42 and no longer returns and is sequentially focused on the front surface of the door 26. By repeating this process, the amount of convergence on the front surface of the door 26 increases. , when the predetermined amount is reached, the packer 24 rotates the door 26 backward through the focusing empty grain culm.
As the door shaft 13 to which the door 26 is attached rotates, the clutch 33 and the idler gear 32 are engaged by the clutch interlocking mechanism 34, and the clutch shaft 12 begins to rotate, while the door 26 further rotates backward. It will be pulled in from the deck plates 4 and 5. This clutch shaft 1
2, the knot shaft 9 also begins to rotate, and the needle 25 is rotated by the clutch shaft 12, causing the needle 25 to move toward the building 15.
After passing the string through the focused empty grain culm by moving upward toward the building 15,
The two ends of the string are tied together and tied, and during this binding, the release arms 17, 18, 19 move backward along the trajectory 23, and when the binding is completed, they move forward, thereby making the binding possible. The grain culms are released backward along both deck plates 4 and 5.

It goes without saying that a plurality of the shutters 42 may be provided at appropriate intervals in a direction substantially perpendicular to the flow of grain culms.

As described above, in the present invention, in a bundling device that includes a guide deck plate that feeds the grain culm in a direction substantially perpendicular to the culm body, a door, and a packer that feeds the grain culm to the door, the guide deck plate In this case, a shutter was provided to protrude upward from the door at a suitable distance from the door toward the grain culm entrance, and the shutter was provided so as to be rotatable only in the direction of the door, and the shutter was biased into an upright state by a spring. If the grain culm overcomes the shutter that falls down against the pressure and the pressing force no longer acts on the front surface of the shutter, the shutter automatically stands up and can reliably prevent the grain culm that has climbed over from falling back. can be performed on both soft and hard objects. Since the shutter is provided so that its position can be adjusted forward and backward in the grain culm feeding direction, depending on the size of the grain convergence in front of the door, if you want to increase the size of the bundle, you can position the shutter at a forward position far away from the front of the door. It does not get in the way when converging, and on the other hand, when the bundle can be made smaller, the shutter can be positioned closer to the front of the door. If the spring force is adjustable, even if the grain culm is soft and weak, it will be possible to get over it without bending it with the shutter.
