Description

[Detailed description of the invention] Conventionally, the horizontal conveying belt of the reaping and tying machine was stretched in a posture that was tilted significantly backwards in the front and back direction as shown in Fig. 5, so straw waste was likely to accumulate in the horizontal conveying section, The horizontal conveyance belt may sink below the guide plate c, resulting in poor conveyance.In order to prevent this, a receiving plate b is attached to the frame body a via the mounting plate d, as shown in Fig. 6. As a result, the number of parts and assembly man-hours increased, resulting in higher costs.

Furthermore, a mounting means for mounting the guide plate d separately from the receiving plate b and the mounting plate d is also required, which reduces assembly accuracy in relation to the receiving plate b, the mounting plate d, and the guide plate d. did.

The present invention solves the above-mentioned drawbacks in a reaping and tying machine which is provided with a rearwardly inclined guide plate and a lateral conveying belt at the rear of the grain culm pulling body, and a tying device is provided at the end of the lateral conveying belt.
A substantially horizontal frame is provided at the bottom of the horizontal conveyance belt, and a transmission wheel, on which a horizontal conveyance belt with lugs is stretched at both ends of the frame, is pivotally supported by a substantially vertical shaft. A substantially vertical guide surface that slides against the inner circumferential surface of the horizontal conveyance belt and causes the lug to protrude from the guide plate is provided near the front between the upper left and right transmission wheels, and a mounting surface of the guide plate that is tilted backward. The problem was solved by installing a mounting seat upright.

The embodiment shown in the drawings will be explained below.1
is a grain culm pulling body attached to the front part of a machine body 3 having wheels 2, 2, a cutting blade 4 is provided at the rear part thereof, and a handle 5 and an engine 6 are arranged at the rear part of the machine body 3. ing.

Immediately after the cutting blade 4, a conveying chain (not shown) for transversely transporting the stock head is provided, and a binding device 7 is provided at a portion facing the terminal end of the conveying chain.

A pair of upper and lower ear side transverse conveyor belts 8 and 9 disposed above the rear part of the conveyor chain are the third to
As shown in FIG. 4, V-pulleys 14 and 15 are supported by substantially perpendicular shafts 12 and 13 on both sides of frames 10 and 11, which are substantially horizontal plates whose front portions are bent diagonally downward. The upper frame 10
On the upper front surface of the lateral conveyor belt 8, there is a substantially vertical guide surface 16a that presses against the inner circumferential surface of the horizontal conveyor belt 8 and causes the lugs 8' to protrude outward from the guide plate 17, and a rearwardly inclined guide surface 16a that supports the guide plate 17. Mounting seat 1 consisting of mounting surface 16b
6 are welded together, and the guide plates 17 include a panicle side guide plate 17a, a middle guide plate 17b, and a stock side guide plate 17c.
The lower part of the ear side guide plate 17a has a screw hole 1 provided in the mounting surface 16b of the mounting seat 16.
8, 18, and the upper part of the middle guide plate 17b is inserted into the screw holes 19, 19 provided in the bent part of the upper frame 10.
The lower part is screwed into the mounting surface 16b of the mounting seat 16, and the upper part of the stock side guide plate 17c is screwed into the screw hole 2 of the lower frame 11.
It is screwed to 0.20.

In the above-mentioned device, the grain culm raised by the grain culm pulling bodies 1, 1 is cut by the cutting blade 4 and the grain culm is cut by the guide plate 17.
The stalks fall upward, and the stalks are transported horizontally by the stalk conveyor chain and the ears by the lugs 8' of the horizontal conveyor belts 8, 9. When the stalks are fed into the bundling device 7, they are tied to the bunker. 21 scrapes and converges the grains, and when a predetermined amount of convergence is achieved, the needles 22 and the knotting section 23 are activated, and the bound grain culms are discharged laterally by the discharging arm 24.

In the horizontal conveyance process, the horizontal conveyance belts 8 and 9 are pushed forward by the guide surfaces 16a and 16a of the pair of left and right mounting seats 16 and 16 between the V pulleys 14 and 15, so that the lugs 8'... The grain culms are securely locked and transported, and the lower edges of the ear-side guide plate 17a and the middle guide plate 17b are close to the upper surfaces of the horizontal conveyor belts 8 and 9, and the upper surfaces of the horizontal conveyor belts 8 and 9 are Since it is approximately horizontal, even if there are some gaps, it is unlikely that straw debris will enter the interior. In addition, 25 in the drawing is a shaft 12 that drives the horizontal conveyance chains 8 and 9.
It is a cylindrical frame with an interior.

The present invention provides a reaping and tying machine in which a rearwardly inclined guide plate and a lateral conveying belt are provided at the rear of the grain culm pulling body, and a binding device is provided at the end of the lateral conveying belt, as described above. A substantially horizontal frame is provided at the bottom, and a transmission wheel, on which a horizontal conveyor belt with lugs is stretched at both ends of the frame, is pivotally supported by a substantially vertical shaft. A mounting seat is erected near the front between the wheels and has a substantially vertical guide surface that slides against the inner circumferential surface of the lateral conveyance belt and causes the lug to protrude from the guide plate, and a rearwardly inclined mounting surface of the guide plate. As a result, the lower edge of the guide plate on the panicle side can be brought close to the upper side of the horizontal conveyance belt, and the gap therebetween is horizontal, making it possible to prevent straw etc. from entering the horizontal conveyance zone. A single mounting seat serves both to support the installation of the guide plate and to regulate the extrusion of the horizontal conveyor belt, eliminating the need to provide a guide plate to prevent the horizontal conveyor belt from sinking in as in the past, and reducing the number of parts and assembly man-hours. This can reduce costs and improve assembly accuracy.
