  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. 1 and 2 are schematic views of the main part of the combine. FIG. 1 is a left side view and FIG. 2 is a rear view. That is, a large Glen tank 3 that is long in the traveling direction of the airframe is mounted on the right side of the combiner body 1 on the airframe frame 2, and the grains in the Glen tank 3 are located on the lower rear side of the Glen tank 3. There is a power transmission device 6 that connects the lower part of a sturdy vertical spiral cylinder 5 that constitutes a part of the discharge auger 4 that discharges the gas to the outside of the machine. The power of the direction is linked.

  Then, below the power transmission device 6, a later-described discharge motor device 7 for driving the discharge auger 4 is mounted. Furthermore, a pair of left and right traveling devices 8 and 8 made of crawlers are provided below the body frame 2.

  Reference numeral 9 in FIG. 1 is a support rod for supporting the upper side of the Glen tank 3 to the vertical spiral cylinder 5 when the Glen tank 3 is opened or closed to perform maintenance or the like on the back side of the Glen tank 3. The Glen tank 3 is pivotably mounted on the vertical spiral cylinder 5 together with the lower power transmission device 6 so that the Glen tank 3 can be opened and closed outside the combine machine body 1 around the vertical spiral cylinder 5.

  Further, the lower side 3A portion of the Glen tank 3 has a funnel shape from both sides as it goes downward as apparent from the rear view of FIG. 2, and the grains stored in the Glen tank 3 Are always gradually filled from the lower side 3A portion, collected by the lateral spiral 11 described later provided on the bottom 3B of the lower side 3A portion at the end of the power transmission device 6 and conveyed by the power transmission device 6 The direction is changed to the vertical direction and then sent.

  Next, FIG. 3 is a side sectional view of the periphery of the power transmission device 6. The lateral spiral 11 has a plurality of spiral blades 12 around a rotating lateral spiral shaft 11A. The grains in the grain tank 3 are conveyed to the power transmission device 6 side by the rotating spiral blades 12.

  The end of the horizontal spiral shaft 11A is provided with a take-off blade 13, and the grains accumulated in the end storage portion T of the horizontal helix 11 are picked up and transferred in the direction of the arrow in the figure. .

  On the other hand, in the inside of the vertical spiral cylinder 5, there is a long vertical spiral 14 on the upper side, which is configured to have a plurality of spiral blades 15 around the vertical spiral shaft 14A. The grains are taken up from the horizontal spiral 11 by the rotation of the vertical spiral shaft 14A, and are lifted and conveyed upward in the vertical direction.

  Then, the rotational power to the vertical helical shaft 14A is taken out from the lower discharge motor device 7 as will be described later, and the intermediate joint shaft supported by the pair of upper and lower bearings 17 and 17 through the connecting portion 16. 18 and further via an intermediate joint shaft 19 thereabove.

  Here, the lower end portion of the vertical spiral cylinder 5 is mounted on the fuselage frame 2, and the vertical spiral cylinder 5 mounting portion of the fuselage frame 2 is connected to the power drive source of the connecting portion 16 located inside. A support boss 20 is provided in advance so that the centering of the shaft can be accurately performed during the connection.

  That is, the outer diameter of the support boss 20 is a size that matches the inner diameter of the lower end of the vertical spiral cylinder 5, while the upper end of the transmission case 21 that transmits the power of the discharge motor device 7, which will be described later. The outer diameter of a certain spigot protrusion boss portion 21 </ b> A has a size that matches the inner diameter of the support boss 20. The positioning with the boss portion 21A is facilitated, and the fitting between the discharge motor device 7 as a power drive source and the lower end portion of the vertical spiral cylinder 5 is made smooth.

  Further, the rotational power to the lateral spiral shaft 11A is caused by meshing between the bevel gear 22 fitted in the intermediate portion of the upper intermediate joint shaft 19 and the bevel gear 23 fitted in the end portion of the lateral spiral shaft 11A. Contrary to the case where the power transmission to the shaft 11A is a normal device, the input portion is configured on the terminal side.

  Next, the structure of the discharge motor device 7 serving as a power drive source (drive device) for the discharge auger 4 will be described with reference to the overall perspective view of FIG. 4 and the entire longitudinal sectional view of FIG. The power generated by injecting and discharging from the pipes 25 and 25 into the discharge motor 26 rotates the output shaft 27 (see FIG. 5) arranged so as to be aligned with the vertical spiral 14 downward, thereby rotating the plane. Is transmitted to the driven gear 29 engaged with the drive gear 28 from the transmission device 31, that is, the drive gear 28 fitted to the output shaft 27, and the transmission shaft fitted upward to the driven gear 29. 30 is transmitted to the connecting portion 16 below the vertical spiral 14.

  And the transmission case 21 which accommodates the said output shaft 27, the transmission shaft 30, and both the gears 28 and 29 is formed combining the upper and lower cases, and as shown in FIG. Mounting bolts 34... To the body frame 2 are attached via the materials 32... And washers 33..., And an oil inlet 35 into the transmission case 21 is provided on the right side of the drawing. It has been.

  Then, according to the present invention, the discharge motor device 7 is inserted from below the machine body frame 2 as shown in FIGS. 1 to 3 and assembled as shown in the rear perspective view of the main part of FIG. That is, the combiner body 1 is attached to the body frame 2 via the elastic bodies 32 so that the vibration of the combiner body 1 is not directly transmitted to the discharge motor device 7, and the washer or the elastic body 33 is inserted from a plurality of upper positions. The mounting bolts 34... Are inserted and the peripheral surface portion of the transmission case 21 is tightened and attached, and the power is transmitted to both the vertical and horizontal spirals 14 and 11 for conveying the grains. However, the portion of the discharge motor 26 that protrudes larger than the transmission case 21 is attached to the longitudinal spiral 14 so as to be located inside the machine frame 2, so that the lateral spiral 11 to the longitudinal spiral 14. The existing parts such as the cleaning window 36 (see FIG. 6) of the takeover portion can be used without change.

  Further, since the transmission case 21 is inserted from the lower side of the machine body frame 2, only this portion is maintained when maintaining the output shaft 27, the transmission shaft 30, the both gears 28, 29, etc., inside these. The length of the detachable operation alone is sufficient, and the maintainability is improved.

  In the present embodiment, the discharge motor 26 is described as hydraulic. However, the discharge motor 26 may be an electric motor, and the horizontal transmission device 31 of the discharge motor device 7 is engaged with the drive gear 28 and the driven gear. 29 may be replaced with a chain or a belt.

  Next, the operation of the present invention will be described. The power from the discharge motor 26 passes through the output shaft 27, both gears 28 and 29, and the transmission shaft 30 through the connecting portion 16 and the upper and lower intermediate joint shafts 18 and 19. Is transmitted to the vertical spiral 14, while the bevel gear 22 provided in the middle of the upper intermediate joint shaft 19 is transmitted to the bevel gear 23 at the end of the horizontal spiral 11, and the stored grains in the glen tank 3 are transferred to the bottom portion. The horizontal spiral 11 provided in 3B is transported to the storage section T on the power transmission device 6 side, and the grains in the storage section T are transferred from the horizontal transport to the vertical transport by the rotation of the harvesting blades 13, so that the vertical spiral 14 is transported upward.

  When maintenance of the back surface of the grain tank 3 is necessary, although not shown, the locking member between the front side of the grain tank 3 and the fuselage frame 2 is released, and the grain tank 3 is moved vertically to the rear. Using the spiral cylinder 5 as a fulcrum, the inner part where the Glen tank 3 is located is opened by rotating outward, and the opening position of the Glen tank 3 is fixed with a locking member (not shown), and then the required work is performed. Once the operation is completed, the Glen tank 3 may be returned to its original position and locked.

  Therefore, according to the present invention, the discharge auger 4 is driven by interlocking the power from the discharge motor 26 with the longitudinal spiral 14, so that when the glen tank 3 is opened and closed, every time as in the conventional device, transmission is performed. Therefore, it is not necessary to perform troublesome work such as detaching the belt (or chain) for each operation, and the Glen tank 3 can be easily rotated to improve workability.

  Further, since the discharge motor 26 is mounted upward and the power is transmitted from the output shaft 27 to the lower side of the vertical spiral 14 via the transmission device 31 disposed in the horizontal direction, the discharge motor 26 and the transmission device 31 are transmitted. However, it does not protrude greatly below the fuselage frame 2 and does not interfere with the traveling of the combine.

  Furthermore, since the discharge motor 26 is located inside the body frame 2, the existing parts such as the cleaning window 36 of the takeover portion from the horizontal helix 11 to the vertical helix 14 can be used as they are without any change.

It is a left view which shows the schematic of the main part of a combine. It is a rear view same as the above. It is a sectional side view of a connection part periphery. It is a whole perspective view of a discharge motor device. It is a whole longitudinal cross-sectional view same as the above. It is a rear surface perspective view of a main part of a combine.
