A timing shaft installed in the cylinder frame 4 that extends to the chain case 4a and the The knot and the discharge arc are connected to each other through a binding shaft in the cylinder frame 4b that extends from the tube toward the knot. drive the system 12.

[0006] Also, above the scraping path formed on the guide plate 9 in front of the binding device 3 and On both sides of the terminal end of the straw removal conveyance device 2, the front end is shallowly overlapped with respect to the straw removal conveyance device 2. The straw consists of a panicle side scraping body 18 that polymerizes, and a stock head scraping body 19 that polymerizes to a larger extent. A raking device 20 is installed, and the ear side raking body 18 is a brush integrated with the upper frame rod 15. It is screwed onto the chain ket 21 to prevent it from moving laterally, and the stock head raking body 19 and chain ke The upper part of the base 4a is fitted into the upper frame rod 15 from behind and the front part is connected with a pin. The knotter case is fixed to the mounting member 22 which has a U-shaped cross section and is movable laterally. A plurality of rolling wheels are attached to the lower frame rod 16 by attaching the mounting member 23 having a U-shaped cross section fixed to the lower part of the Since it is fitted so that it can be moved laterally through Lateral movement can be adjusted.

[0007] A support device for the root alignment plate 25 facing the stock base side of the converging unit 10 of the binding device 3 is provided in an upper direction. A U-shaped fitting 26 is fitted and fixed to the cylinder frame 4b, and the rear end is screwed into the fitting 26. A plate-shaped support plate 27 extends forward, and a support plate 27 has a support plate 27 at both front and rear ends thereof. triangular link plates 30, 31 whose one corner is pivoted by fulcrum shafts 28, 28; The front corners are connected to form a link 32, and the front end is the front link plate 30. It is pivoted at the rear corner and the rear part is connected to the rear part of the rear link plate 31 via a connecting rod 33a. The support link 33 is connected to the link 32 and is parallel to the link 32. , the alignment plate 25 is fixed to the downwardly bent portion at the rear of the support link 33. The rod 34 connected to the rear link plate 31 has a spline shaft (or hexagonal It is driven by the output shaft of a bevel gear case 35a mounted on the shaft 35 so as to be able to move laterally. Since it is interlocked and connected to the crank arm 37, the root alignment plate 25 is While maintaining the force, it partially penetrates into the low part 9a formed at the rear of the stock base side of the guide plate 9. In this state, the collected straw is reciprocated in the direction of the culm to align the roots.

[0008] As shown in FIG. 1, the guide plate 9 has a packer 6 and a needle 7. Almost the entire surface of the panicle side of the gap and the outer side of the part corresponding to the root alignment plate 25 on the plant base side. The area corresponding to the operating range of the root alignment plate 25 is located at the lower part 9a as shown in FIG. The root alignment plate 25 has a shape in which its lower edge approaches the upper surface of the lower part 9a. It is suspended so that it can reciprocate in the horizontal direction.

[0009] Next, to explain the transmission device, the right side frame 14 also serves as a transmission case. The sprocket 38 attached to the input shaft 38a supported at the bottom of the A sprocket attached to the shaft of a cutter 39 interposed between the device 1 and the binding device 3 40 via a chain, and the left side of the input shaft 38a is spliced on the inner circumference. The binding input shaft 41 is formed into a cylindrical shape with a spline shaft and is capable of transmitting power. The side frame 14 is supported on the upper part of the side frame 14. The transmission shaft 42 is driven by the input shaft 38a via a sprocket and a chain. Since it is inserted into the chain case of the ear side scraper 18 mentioned above, there is a raised protrusion at the front end. The chain has tines that are pulled out, moved backwards on the lower side, and then laid down from the rear. The shaft 43 is connected to the bundling input shaft 41 which is driven and protrudes from the knotter case 5 toward the stock base. This shaft 43 connects the stock head scraper 19 and the bevel gear case 35a. Sprockets 46, 47 and chain 48 in the chain case 45 and splices It is driven via the engine shaft 35. Additionally, an electric motor is installed at the bottom of the side frame 13 on the stock side. A screw shaft 50a driven by the motor 50 is mounted on the stock side of the lower mounting member 23. Since it is screwed into a nut 23a fixed to the end, the electric motor 50 can be rotated forward or reverse. When rotated, the stock head raking body 19, binding device 3, root alignment plate 25, etc. reciprocate in the horizontal direction. move.

0010 Further, the front outer side of the support plate 27 is connected to the control circuit of the electric motor 50. A pair of left and right stock head sensors 51 and 52 are provided, and the end of the straw stock is connected to both sensors. If it comes off the sensors 51 and 52, it will be detected that it is a short culm, and this detection signal will cause the electric The motor 50 rotates forward to move the stock head raking body 19 and root alignment device toward the panicle side, and remove the stock. When the base end enters between both sensors 51 and 52, the electric motor 50 stops and both sensors 51 and 52 When both the stock sensor 51 and 52 detect the stock stock, the electric motor 50 moves to the end of the stock. Rotate in the opposite direction until it enters between both stock base sensors 51 and 52, and move the root alignment board etc. to the stock base side. As a result, the stock raking body 19 rakes the discharged waste straw at an appropriate position, The root alignment board 25 is reciprocated and oscillated at a desired position relative to the stock end of the straw being scraped. Perform accurate root alignment.

[0011] In the above-mentioned combine harvester, the threshing device 1 performs threshing after the handling depth is adjusted. The waste straw that has been processed and discharged from the culm is transported by the waste straw conveying device 2. It is discharged from the rear end, and is carried out by the tines of the panicle side raking body 18 and stock head raking body 19. It is raked toward the convergence part of the rear binding device 3, and during this time, the root alignment plate 25 is not converged. The stem of the waste straw is struck in a reciprocating motion to align the roots, but at this time, the waste straw is -6 and the needle 7 are supported by the guide plate 9, and the stock side is separated from the guide plate 9. The root alignment plate 25 is in a raised state, protruding above the lower part 9a of the It floats up or becomes flexible and hangs due to lodging grain culms, etc., and only the base end of the plant is in the low part. By tapping the end of the plant that is in light contact, it will ensure that all the straw in the lower layer is thoroughly rooted. Then, the packer 6 scrapes into the convergence part, and when the predetermined amount of convergence is achieved, the door 8 senses Since it is activated, the one-turn clutch engages and the needle 7 and the knotting section operate to knot the knot. , the discharge arm 12 discharges the bundle while cutting the knots.

0012 In addition, when the waste straw is a short culm, the electric motor 50 is started to connect the bundling device 3 and the stock. By moving the original raking body 19 etc. to the panicle side, the stock base raking body 19 can scrape the stock base side. If the straw is a long culm, the electric motor 50 is rotated in the opposite direction. Then, the binding device 3 and stock head scraper 19 move toward the stock head side. At that time, rake in the ear side Since the body 18 does not move and is always at the appropriate position for raking the ear side, the straw removal conveying device 2 Even if the straw discharged from the straw is in an irregular position, it will surely catch the ear side and rake it in, allowing it to be scraped at the base of the stock. The inserting body 19 scrapes in the largely protruding stock end side.

[0013]

[Effect of the idea]

Since the present invention is constructed as described above, the root leveling plate 25 When leveling the roots with Even if the grain becomes bent or becomes flexible and droops due to a lodging grain culm, etc. The base end of the stock will be in a state where it is lightly touching the low part 9a, and the base end of the stock will be placed in the root alignment plate. 25, we were able to ensure that the stocks were aligned without any omissions, and as a result, the stock prices were well aligned. It can be tied into bundles, and it also prevents tying errors caused by irregular culm posture and tangles. It is possible to prevent discharge errors caused by
