Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shell culm conveying device that is capable of accurately taking over shell culms in an apparatus in which two shell culm carriers are provided with their conveying directions being changed.

In a combine harvester, a plurality of shell culm carriers (a combination of a cheno and a pruning rail) are installed to lift the shell culm from the reaping section, supply it to the threshing section for threshing processing, and then transfer the culm to the cutting section. Or they are being transferred to the binding section.

During the period from reaping to threshing, the husk is subjected to various actions such as combing, gathering, reaping, lifting and conveying, adjusting the gripping length (handling depth), and changing direction. The culm must be transported without any bends or disturbances.

In addition, the direction in which the shell culm is supplied to the threshing section is determined by two methods: one is clamping it in the horizontal direction perpendicular to the direction of movement of the machine and the other is transporting it in the direction perpendicular to the direction of movement of the machine.
There are various cases.

In such a case, the culm changes its posture from a vertical state to a horizontal state, and its direction is also changed.

In order to change the posture and direction of the culm as described above, 1.
This is difficult to do with a book shell conveyor, and generally multiple books are used.

The present invention provides a device that can easily change the inheritance and posture of the shell culms when using the plurality of shell culm carriers.

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 is a perspective view of a combine harvester implementing the present invention.
A cutting blade 2 is provided at the bottom of the combing device 1, and a threshing section 3 is provided at the rear of the combing device 1. The stock carrier 5 is arranged so as to circulate in a planar manner up to the vicinity of the
A culm supply carrier 6 of the threshing section 3 is provided overlapping the longitudinal feed end 5a of the carrier.

Furthermore, a conveyor 7 for adjusting the handling depth is provided below the stock source conveyor 5.

In addition, 8 is a crawler, 9 is a power part, and 10 is an operation part.

Next, to explain the transportation state of the shell culm, the shell culm A is combed by the combing device 1, cut by the cutting blade 2, and transported to position B, then transported to position C, lifted up, and then moved to position E. The grains are lifted up, transferred to the shell culm supply carrier 6 at the bending part F, and supplied to the threshing section 3.

As can be seen from Figure 1, the tip of the ear is the culm supply port 4 of the threshing section 3.
It can be seen that the culm is located near one end and does not move much, and only the base of the stock moves significantly, while the culm changes its posture moment by moment.

Next, the structure of the main part of the present invention will be explained.

FIG. 2 is a plan view showing the shell culm conveying section of the combine, and FIG. 3 is a side view thereof.

As shown in FIG. 2, the stock carrier 5 has a horizontal feed surface 5C formed next to a vertical feed surface 5b, and the culm supply conveyor of the threshing section 3 is arranged so as to overlap in parallel with this cross feed surface 5C. 6 is provided.

In addition, the stock carrier 5 is provided so as to circulate in a plane, whereas the shell culm supply carrier 6 is provided so as to form a circumferential surface that is substantially perpendicular to this, and the shell culm is approximately The grain is fed to the threshing section 3 after changing its posture from standing upright to lying on its side.

A clamping rail 15 is provided on the stock carrier 5 and extends almost to the vicinity of the end of the vertical feed surface 5b, which is a lifting section, but does not extend to the bent portion following the horizontal feed surface 5C.

Another guide rod 16 extends from near the end of the clamping rail 15, but this guide rod 16 does not extend between the two upper and lower chain plates, but above the chain plate located on the upper surface.

(FIGS. 4 and 5) Therefore, from the bending part of the stock carrier 5 to the transverse feed surface 5C, the culm is transported so as to lie on the chain plate.

Further, a clamping rail 17 is extended parallel to the guide rod 16 so as to be positioned between the chain plates of the culm supply body 6.

FIG. 4 is a side view of the overlapping portion of the conveyor shown in FIG. 3, and FIG. 5 is a perspective view. Next, the conveying state of the culm will be explained with reference to these.

The culms that are conveyed along most of the vertical feeding surface 5b of the stock conveyor 5 are in states C and D as shown in FIG. The clamping is released, and then it is held down by the guide rod 16 and clamped on the chino board of the cross-feeding surface 5C, and at the same time, the stock base is lifted and inserted between the culm supply carrier 6 and the clamping rail 17. Ru.

The husk culm, which is held between the guide rod 16 and the cross-feeding surface 5C, swings its stock base as shown by the arrow X due to the relative movement caused by the movement of the traverse-feeding surface 5C, and the husk culm feed port 4 of the threshing section 3 swings as shown by the arrow X. The shell culm supply conveyance body 6 takes over the state parallel to the culm supply conveyance body 6.

The present invention is based on the stock transport body 5 which rotates in the plane direction as described above.
The clamping rail 15 is omitted in the middle, and another guide rod 16 is then placed on the upper side of the chain plate of the stock carrier 5, and further inside the conveyance path on the outer peripheral side of the chain plate. Since the culm is extended to the threshing section 3 from the stock carrier 5,
Since the shell culm supply conveyor 6 of the husks is carried over in a large circular arc at the stock base and conveyed parallel to the shell culm supply port 4 of the threshing section 3, one of the conveyors is arranged perpendicularly thereto. When the culm is transferred to another carrier, the joint is carried out extremely smoothly, and there is no breakage of the stem and no disturbance of the culm.

In particular, the present invention provides clamping rails on two sides, one in the normal position relative to the chain and the other on the side of the chain plate, and furthermore, the culm, which is clamped by the clamping rails in the normal position, is continuously provided on the side of the chain plate. Since the culm is held in place by the guide rod, the posture of the culm can be smoothly changed in the vertical plane and in the horizontal plane, that is, three-dimensionally.

The device of the present invention is characterized by extremely effective use of the clamping rail and guide rod, and as can be seen from the drawing, the number of parts is significantly reduced, which not only reduces manufacturing costs but also reduces the possibility of failure. It has the characteristics of not occurring often.
