Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a straw scraping device in a combine knotter that binds straw discharged from a self-throwing threshing device.

[0002]

[Prior Art]

 Conventionally, a straw transfer device was installed above the threshing device of a self-removing combine, and the straw discharged from the culm was conveyed diagonally toward the ear side and discharged from the end. There is already known a combine knotter in which a pair of left and right star wheels are scraped into a binding device at the rear by a scraping device such as a star wheel.

[0003]

[Problems to be solved by the device]

 The known self-removing combine combines the treatment depth before threshing treatment, so the tip position of the straw discharged from the culm outlet is almost constant, but the plant origin position differs significantly depending on the culm length. In the long culm, the plant origin protrudes sideways from the straw transporter, and the culm diameter is larger than the spike side and a large amount of straw debris is attached to it. Despite the transfer delay while being conveyed, the straw scraping device had the start point at the part corresponding to the end of the straw transfer device, so the stocker side did not transfer after transfer. As it was left, it was scraped into the bundling part of the bundling device, which disturbed the battering posture of the straw and entangled, resulting in bundling and ejection errors. Also, if a root aligning plate is provided on the root side of the focusing part, it will be focused in a bent posture due to the transfer of the root, so when the root end plate is hit, the straw culm will bend. I couldn't get enough roots.

[0004]

[Means for Solving the Problems]

 According to the present invention, a binding device is attached to the rear part of the threshing device mounted on the machine base having a traveling device, and the straw discharged from the straw transfer device of the threshing device is bound to the front part of the binding device. A scraping device for scraping toward the device, wherein the scraping device is composed of a stock-source scraping body facing the left and right sides of the rear end of the straw-conveying device and an ear-side scraping body.

【Example】

 An embodiment of the present invention will be described in more detail with respect to the combine knotter shown in the drawings. 1 is a threshing device mounted on a machine base having a traveling device, and a conventional threshing device is omitted from the drawings. There is a pretreatment device consisting of a reaping device similar to that used and a culm conveying device that adjusts the cutting depth to the culm and supplies it to the threshing device 1. On the dust sorting chamber, there is provided a straw conveying device 2 which is inclined so that the rear part thereof is displaced toward the ear side in a plan view, and the bundling device 3 includes a lower knotter case 5, a packer 6, a needle 7 and The door 8 is mounted, and a knotting part composed of a building, a holder, and a knotting guide 11 and a discharge arm 12 are installed above the bundling part 10.

The knotting portion and the discharging arm 12 are driven via the binding shaft in the cylindrical frame 4b extending toward the portion.

Then, above the scraping path formed on the guide plate 9 in front of the bundling device 3 and on both sides of the end of the straw conveying device 2, side surfaces with respect to the straw conveying device 2 are formed. A straw scraping device 20 composed of a short spike-side scraping body 18 whose front end portion is shallowly superposed and a long stock yuan scraping body 19 superposing more than that is installed, and these scraping bodies 18 are provided. , 19 chain cases have a pair of front and rear sprockets that are pivotally supported, and the tines 18a, ..., 19a, ... pivotally attached to a chain stretched over them are guide rails installed along the inside of the lower part. As a result, the straw is scraped while standing up and protruding downward at the front end traveling portion and shifting to the rear side, and the ear side scraping body 18 is screwed to the bracket 21 integrated with the upper frame rod 15 and does not move laterally. As described above, the stock scraper 19 can be laterally moved to the upper frame rod 15. Since it is attached to the attachment member 22 having a U-shaped cross section and fitted to the knotter case 5, the movement can be adjusted integrally with the binding device 3.

The support device for the root aligning plate 25 facing the root side of the bundling unit 10 of the bundling device 3 includes a U-shaped mounting metal 26 fitted and fixed to the upper tubular frame 4 b, and the mounting metal 26. A support plate 27 having its rear end screwed to extend forward, and a triangular link plate 30 in which one corner is pivotally supported by fulcrum shafts 28, 28 at both front and rear ends of the support plate 27. , 31 and a link 32 connecting the front corners thereof, and the front end of the link 32 is pivotally attached to the rear corner of the front link plate 30 and the rear part is connected to the rear part of the rear link plate 31.

The root aligning plate 25 is fixed to a downward bent portion of the rear portion of the support link 33. , The rod 34 connected to the rear link plate 31 has a spline shaft (or a hexagonal shaft). Since the bevel gear case 35a mounted laterally on 35 is connected to the crank arm 37 driven by the output shaft of the bevel gear case 35a, the root aligning plate 25 maintains the front-back posture and the rear portion of the guide plate 9 on the root side. The roots are aligned by reciprocating in the culm direction of the straw that is converged in a posture of partially penetrating into the lower portion 9a formed in.

Next, the transmission device will be described. The side frame 14 on the right side also serves as a transmission case, and the sprocket 38 mounted on the input shaft 38a supported on the lower part of the side frame 14 is provided between the threshing device 1 and the binding device 3. Driven through a chain by a sprocket 40 attached to the shaft of a cutter 39 interposed between the two, the left side of the input shaft 38a is formed into a tubular shape having an inner peripheral spline, and a bundling input shaft 41 composed of a spline shaft can be transmitted. The transmission shaft 42 is slidably fitted in the state and is supported on the upper portion of the side frame 14 and is driven by the input shaft 38a through the sprocket and the chain.

The shaft 43 connects the stock root scraping body 19 and the bevel gear case 35a to the sprockets 46 and 47 in the chain case 45. And the chain 48 and the spline shaft 35. Further, since the screw shaft 50a driven by the electric motor 50 attached to the side frame 13 on the stocker side is screwed into the screw body fixed in the transmission case 45, the electric motor 50 is not directly connected. When it is rotated in the reverse direction, the stock scraping body 19, the binding device 3, the root aligning plate 25 and the like reciprocate laterally.

Further, a pair of left and right stock origin sensors 51 and 52 connected to a control circuit of the electric motor 50 are provided outside the front portion of the support plate 27, and the stock origin end portion of straw is both sensors. When it deviates from 51, 52, it is detected that it is a short culm, and the detection signal causes the electric motor 50 to rotate in the forward direction to move the stock scraping body 19 and the root aligning device to the ear side, and the stock end part When entering between the sensors 51 and 52, the electric motor 50 stops, and when both stock yuan sensors 51 and 52 detect the stock yuan, the electric motor 50 enters the stock stock end between the stock yuan sensors 51 and 52. Until the root aligning plate is moved to the root side until the root aligning plate and the like are moved to the stock root side, the stock root scraping body 19 scrapes the appropriate position of the discharged straw, and the root aligning plate 25 is scratched. Oscillate back and forth at the desired position with respect to the base end of Make accurate root alignment.

In the combine knotter described above, the straw that has been threshed by the threshing device 1 after being adjusted in handling depth and discharged from the culm outlet is conveyed by the straw conveying device 2 and from the rear end thereof.

When this is done, the door 8 senses and operates, so that the one-rotation clutch is engaged and the needle 7 and the knot are actuated to make a knot, and the discharge arm 12 discharges the bundle while pulling out the knot.

When the straw is short culm, the electric motor 50 is activated to move the binding device 3 and the stock scraper 19 to the ear side, so that the stock scraper 19 moves the stock side. When the straw is stopped and the straw is long culm, when the electric motor 50 is rotated in the reverse direction, the binding device 3 and the stock scraping body 19 move to the stock stock side. At that time, since the ear-side scraping body 18 does not move and is always at the ear-side scraping proper position, even if the posture of the straw discharged from the straw-conveying device 2 is disturbed, the ear-side scraping member 18 is surely engaged. When stopped and swept, the stock scraping body 19 rapidly overlaps the stock carrier side when the tines 19a ... After removing the transfer delay by scraping into the rear part, the rear part cooperates with the straw-conveying device 2 in the rear part, and in the latter half of the scraping process of the scraping device and in the process of being scraped into the focusing part by the packer 6. When the root aligning plate 25 hits the root end and aligns the roots, the straw is collected in a state where there is no delay in transferring the roots, so that the root aligning plate can be reciprocally moved to align the roots neatly.

 Since the treatment depth of the known self-removing combine is adjusted before threshing treatment, the tip position of the straw discharged from the outlet is almost constant, but the origin of the strain differs significantly depending on the rod length. In Nagarod, the root of the plant greatly protrudes laterally from the straw-transporting device, the culm diameter is larger than that of the ear side, and a large amount of straw debris is attached to the straw-bearing device. Despite the transfer delay during transport, the straw scraping device had the start of scraping at the part corresponding to the end of the straw transport device, so the stocker side did not transfer. It was scraped into the bundling part of the bundling device as it was, and as a result, the focusing posture of straw was disturbed and entanglement occurred, resulting in bundling errors and ejection errors. Also, if a root aligning plate is provided on the root side of the focusing part, it will be converged in a bent posture due to the transfer of the root, so when the root end is hit by the root aligning plate, the straw culm will bend. I couldn't get enough roots.
