In front of the chassis 51, a driving part B is formed on the right side in the traveling direction. In this driving part B, a steering panel 56 for projecting a steering lever 57 and a shift lever 58 is disposed at the foremost part. A seat 59 is disposed behind the seat 59, and a reaping clutch lever 60 and a threshing clutch lever 61 are disposed on the left side of the seat 59.
[0008]
A cutting portion A is formed on the left front side of the chassis 51, that is, on the front left side of the operation unit B.
This embodiment is a two-row cutting, and a pair of left and right pulling devices 23L and 23R that project forward the weed plates 22L, 22M, and 22R are arranged at the forefront of the cutting part A, and at the rear of the lower end thereof The cutting blade 24 and the starwheels 25L and 25R for picking the cereal are disposed, and the upper conveying device 30 and the vertical conveying device 31 are disposed behind them.
The cereal is raised upright by the pulling device 23, the root portion is scraped into the cutting part A by the star wheel 25, cut by the cutting blade 24, and the ear side is the upper conveying device 30. The stocker side is held and transported by the vertical transport device 31 and is inherited by the feed chain 49 of the threshing section C.
[0009]
As shown in FIG. 3, the transport device 31 has a U-shaped flange 34 disposed on the upper side from the right side of the upper transport device 30, and extends from the upper portion of the upper transport device 30 to the base of the U-shaped flange 34 in FIGS. 1 to 3. The upper cover 38 shown in the figure is covered, and the upper end of the pinch guide mounting plate 40 extending to the side of the lower vertical conveying device 31 passes through the left side of the upper conveying device 30 at the left end of the U-shaped rod 34. The part 34a is fixed using bolts and nuts.
The vertical conveyance pinch guide 37 is fixed to the lower end of the pinch guide mounting plate 40 with bolts and nuts, and the upper transfer guide 36 is also fixed to the approximate center of the pinch guide mounting plate 40 with bolts and nuts. ing.
[0010]
The pinch guide mounting plate 40 of the present invention is made of a rectangular steel plate and has rigidity, and is provided with a fitting insertion hole for inserting and attaching the tip of the U-shaped rod 34 at the top. 4, from the center to the lower part, as shown in FIG. 4, a "U" -shaped slit 40a is provided in the center of the pinch guide mounting plate 40 so that the lower part is opened to form two pieces. The upper conveyance guide 36 is attached to the central piece 40b surrounded by 40a, and the vertical conveyance pinch guide 37 is attached to the tip side piece 40c of the other piece of the pinch guide mounting plate 40. It is fixed using a nut.
[0011]
Further, the pinch guide mounting plate 40 can also be configured as shown in FIG. 5, and is provided with a slit 40a 'cut out in an inverted L shape from the center to the lower portion, and the center of the pinch guide mounting plate 40'. An upper conveyance guide 36 is attached to the lower end of the side piece 40b ', and a vertical conveyance pinch guide 37 is attached to the other tip side piece 40c'.
[0012]
Further, the pinch guide mounting plate 40 can also be configured as shown in FIG. 6, and a mounting portion 40e of the upper conveyance guide 36 is provided at the center of the pinch guide mounting plate 40 ", and the tip side piece 40c. When the attachment portion for attaching the vertical conveying pinching guide 37 is formed, the constricted portion 40d is formed between the attachment portion 40e and the tip side piece 40c ", and a force is applied to the tip side piece 40c" The distal end side piece 40c "is configured to bend larger than the attachment portion 40e.
[0013]
With this configuration, the front end side piece 40c (40c ′, 40c ″) to which the vertical conveyance pinch guide 37 is fixed is provided on the central side that serves as an attachment portion of the upper conveyance guide 36 by the slit 40a or the constricted portion 40d. The pieces 40b (40b 'and 40e) can be bent separately.
Therefore, when transporting a large amount of cereals, the tip side piece 40c (40c ', 40c ") bends larger than the central side piece 40b (40b', 40e), which is the mounting portion, and holds the cereals, respectively. It remains and can be held evenly regardless of the amount of grain.
[0014]
Further, when a large number of cereals are conveyed by the vertical conveying device 31, the vertical conveying pinch guide 37 is greatly lifted and the pinch guide mounting plate 40 is warped, and the upper conveying guide 36 is used for vertical conveying. The pinch guide 37 is attached to another attachment piece (40b), so it can be bent with a small bend, and can hold and transport the culm with an appropriate holding force.
[0015]
【The invention's effect】
The present invention has the following effects by being configured as described above.
First, in the case where many grains are conveyed by the vertical conveying device, the vertical conveying pinch guide is greatly lifted and the pinch guide mounting plate is warped, but the pinch guide mounting plate 40 is By comprising the rectangular steel plate, the cereal can be held and transported with an appropriate holding force even when warped up.
Secondly, it becomes possible to bend the upper conveying device and the vertical conveying device separately, and when the amount of cereals transported is large, both the upper conveying guide and the vertical conveying nip guide depend on the amount of cereals. When transferring backward, the tip part is less likely to come off the tine of the upper transfer device, or the conveyance posture is less likely to be lost. Can be transported.
