【Example】

An embodiment of the present invention will be explained in more detail about the combine knotter shown in the drawings. 1 is a threshing device mounted on a machine base with a traveling device, and after the culm A waste straw conveying device 2 is installed above the waste sorting room in the section to pinch and convey waste straw, and a bundling device 3 is installed. Similar to the conventional one, the lower knotter case 5 has a packer 6, needle 7, and door. 8 is installed, and a building, a holder, and a nodule guide 11 are installed above the focusing section 10. It is constructed by constructing a knot and a discharge arm 12. A mounting frame 17 for attaching the bundle device 3 to a cutter 39 (described later) is attached to left and right side frames 13, 1. 4 and upper and lower frame rods 15, 16 that connect them, the binding device 3 consists of frame rods 1 5 and 16 so that it can be moved laterally, and the cylinder frame extends from the knotter case to the stock side. The timing shaft installed in chain case 4a extends from the chain case 4a and its upper part to the node. The knot part and the discharge arm 12 are driven through the binding shaft in the cylinder frame 4b extending toward the Ru.

[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 socket 21 to prevent it from moving laterally. The upper part of 4a is fitted into the upper frame rod 15 from behind and the front part is connected with a pin. It is fixed to a mounting frame 22 with a U-shaped cross section that allows for more horizontal movement, and is mounted under the knotter case 5. The mounting member 23, which has a U-shaped cross section and is fixed to the Since they are fitted together so that they can be moved laterally, the stock head scraper 19 and the binding device 3 can be moved as a unit. can be adjusted dynamically.

[0007] The scraping claws 19a of the stock scraping body 19 pivot on the chain at a constant pitch. The front end of the chain protrudes from the guide rail inside the chain case. Shifting backward, the base at position A (close to the front end of the puckering trajectory a of the packer 6) It is interlocked with packer 6 and needle 7 at the timing when it leaves the guide rail. Therefore, the raking claws 19a and 19a fall down because their progress is obstructed by the straw that has been raked in. ・The chain and the binding device 3 are connected to a scraper that stands close to the binding device. The claw 19a enters the needle that has entered the convergence part 10 to hook the string when the one-turn clutch is engaged. The claws 19a are spaced apart from each other by approximately 1/2 of the pitch b of the claws 19a. As shown in FIG. 3, there are short claws between the claws 19a By attaching the claw 9b, it is possible to prevent a delay in rake-in, especially a delay in rake-in of the stock. At the same time, the pressure applied to the back of Needle 7 when it is in operation is further reduced. can be reduced.

[0008] 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 that extends forward with the support plate 27 attached, and a plate-shaped support plate 27 that Triangular link plates 30 and 31 whose respective corners are pivoted by fulcrum shafts 28 and 28 , a link 32 connecting their front corners, and a link plate 3 whose front end is forward. A connecting rod 33a is pivotally connected to the rear corner of 0 and the rear part is closer to the rear of the link plate 31. The support link 33 is connected to the support link 32 and is parallel to the link 32. The alignment plate 25 is fixed to the downwardly bent portion of the rear part of the support link 33. The rod 34 connected to the rear link plate 31 has a spline shaft (or It is driven by the output shaft of a bevel gear case 35a that is mounted on the hexagonal shaft 35 so as to be able to move laterally. Since it is interlocked and connected to the crank arm 37 that is moved, the root alignment plate 25 can be moved forward and backward. While maintaining the facing position, enter 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.

[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 has an inner peripheral spline. The bundling input shaft 41, which is formed into a cylindrical shape and consists of a spline shaft, is in a state in which transmission is possible. The input terminal is slidably fitted to the side frame 14, and is supported on the upper part of the side frame 14. The transmission shaft 42 driven by the shaft 38a via the sprocket and chain is as described above. Since it is inserted into the chain case of the ear-side scraping body 18, it protrudes upright at the front end. Drives a chain with tines that moves rearward on the lower side and then collapses from the rear. Then, the shaft 43 is connected to the binding input shaft 41 that protrudes from the knotter case 5 toward the stock side. , this shaft 43 connects the stock head scraping body 19 and the bevel gear case 35a with a chain. Sprockets 46, 47, chain 48 and spline shaft inside case 45 35. In addition, an electric motor 5 attached to the side frame 13 on the stock side The screw shaft 50a driven by Therefore, when the electric motor 50 is rotated forward and backward, the stock head scraper 19, The binding device 3, the root alignment plate 25, etc. reciprocate in the lateral direction.

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 onto the guide plate 9, and it is passed through the panicle side raking body 18 and stock head raking body 19. The scraping claws 19a... are scraped toward the convergence part of the rear binding device 3, and the scraping claws 1 9a is after plowing to a position approximately equal to the front end of the plowing locus of packer 6 in side view. The packer 6 scrapes it into the convergence part in synchronization with the scraping claw 19a, and collects it by a predetermined amount. When the focus is focused, the door 8 is sensed and activated, so the one-turn clutch engages and the needle 7 and The knot section operates and knots, and the release arm 12 discharges the bundle while removing the knot, but the front When the needle 7 enters the nodal part via the B position of the convergence part 10 for stringing, The claw 19a is spaced apart from the needle 7 by approximately 1/2 of its pitch as shown in the figure. The distance between the needle 7 and the claw 19a is larger than that of the conventional method. The pressure on the needle 7 and the scraping pawl 19a decreases, and the force in the transmission mechanism decreases. It is possible to prevent the shearing pin from breaking or becoming clogged with straw.

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 scraping end position of the scraping claw 19a of the scraping device is It is possible to carry out reliable raking and delivery by bringing the raking machine closer to the raking start position of the packer 6. However, when the needle 7 advances to the convergence part 10 to operate the string, the scraping claw 19a is separated from the needle 7 by approximately 1/2 of the installation pitch of the scraping claw 19a, and passes through the straw. There is no compression at the same time, which may cause clogging of the culm, or sharpeners in the transmission mechanism. It is possible to prevent the tube from breaking or breaking.
