Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a clamping and conveying device for supplying grain bundles to a threshing feed chain with a receiving port located on the outer side of the machine body, and This invention relates to a harvester in which a grain supply stand for a chain can be freely switched to an upright storage position along a wall of a threshing device having a grain supply port.

[Conventional technology]

The above-mentioned harvester can maintain this posture without having to strictly adjust the posture of the supplied grain culm relative to the threshing device so that the grain culm can be smoothly fed into the handling room as in the case of directly feeding the grain culm to the threshing device. Adjustments are made using the clamping and conveying device, which allows grain culms to be supplied quickly, and when one person is threshing grain culms that have been hung to dry on rice racks in places where the machine cannot approach, such as on banks near the field, it is possible to quickly supply grain culms from the rice racks. The grain culm is configured so that the grain culm can be quickly and easily fed from the place where the rice rack is installed without having to carry the removed grain culm and walk from the rice rack to the threshing device to feed it to the threshing device,
Furthermore, the structure is such that grain culms that cannot be fed by the clamping and conveying device due to breakage of binding strings, etc., are directly fed to the threshing feed chain using a feeding stand. However, in the past, the grain culm conveyance guide rail constituting the clamping conveyance device was extended from the threshing device or the traveling machine body, or from the support frame of the endless rotary chain for grain culm conveyance constituting the clamping conveyance device. It was attached to a special support frame.

[Problem that the invention attempts to solve]

Conventional harvesters have been provided with a dedicated support frame for the conveyance guide frame, which has been disadvantageous both in terms of structure and cost in terms of the structure of the clamping and conveying device.

An object of the present invention is to enable a gripping and conveying device to be constructed with a simple structure and at low cost.

[Means for solving problems]

The feature of the present invention is that in the above-mentioned harvester, the clamping and conveying device comprises:
When a member supporting the grain culm conveying guide rail in a biased state approaching the grain culm conveying endless rotary chain is placed on the grain culm supply stand in the upright storage position, the guide rail is in the chain acting position. The functions and effects are as follows.

[Effect]

The conveyance guide rail can be attached to the frame supporting the support member by effectively utilizing the grain supply stand.

[Effect of idea]

Therefore, the clamping and conveying device can be constructed without requiring a special support frame for the guide rail support member, and the operation can be advantageously performed as described above, which is advantageous both in terms of structure and cost.

〔Example〕

As shown in FIGS. 3 and 4, a threshing device 4 is mounted behind the driving section 3 of the self-propelled aircraft, which has a crawler traveling device 1, a control section 2, etc. arranged at the rear end of the aircraft. A harvester is constructed by providing a bagging unit 6 for grains from the delivery tube 5 of the device 4 behind the driving unit 3 and supplying the grains by the conveying device 7 of the threshing device 4. There is.

The grain culm conveying device 7 includes a terminal side clamping and conveying device portion 7a disposed above the grain culm guide bottom plate 8 relative to the grain culm supply port 4a of the threshing device 4 along the longitudinal direction of the machine, and this terminal side conveying device portion. It consists of a starting end side clamping and conveying device part 7b extending from the starting end of the self-propelled machine to the lateral outside of the self-propelled machine, and the grain culm bundle is placed in an inverted position with the ear side facing down at the receiving port 7c located on the lateral outward side of the self-propelled machine. In addition, the grain culm bundles are fed to the threshing feed fan 9 while being changed to a sideways posture as they are transported.

That is, as shown in FIG.
An endless chain 10 in which a group of protrusions having a plurality of projections a are arranged at set intervals in the chain longitudinal direction is attached to a frame 11 in a state in which it is interlocked with the terminal end side conveyor section 7a so as to be driven by the transmission from now on. A conveyance guide rail 12 is rotatably mounted and is opposed to the conveyance path side of the chain 10.
is attached to the frame 11 via the frame 13 and the U-shaped support arm 14 in a state where it is biased toward the chain 10, and the supplied grain culm bundle is transferred to the chain 1.
0 and the guide rail 12 so that the tip side hangs down, and the grain is conveyed to the terminal side conveyor section 7a at a pitch determined by the arrangement interval of the protrusion group, which is set so as not to cause an abnormal increase in the threshing load. It's like this.

As shown in FIGS. 3 and 4, the terminal end conveying device portion 7a is constructed by attaching an endless chain 15 having grain culm locking protrusions 15a continuously in the longitudinal direction of the chain. 16, and the chain 15
Conveyance guide rail 17 facing the conveyance path side of
is attached to the support member 18 in a state where it is biased toward the chain 15, and the stock side of the grain culm bundle from the starting end side conveyor section 7b is connected to the chain 15 and the guide rail 17.
The head side is pulled up and placed on the opposite side of the guide bottom plate 8 from the threshing feed chain 9, and the stock side is further placed on the threshing feed chain 9 while remaining in this placed state. Grain culms inherited in an inverted position from the starting end side conveying device section 7b are transferred by clamping them to above the starting end of the grain culm and dropping them onto the grain culm guide supply rod 19 for the threshing feed chain 9 as shown in FIG. The posture of the bundle is changed to lie sideways and the bundle is fed to the threshing feed chain 9.

As shown in FIGS. 1 and 2, one end of a support rod 21 is pivotally connected to a grain culm supply stand 20 for the threshing feed chain 9, and the other end of the support rod 21 is pivotally connected to the other end of the connecting cylinder. 22, the grain culm supply stand 20 is connected to a support frame 23 extending from the threshing device 4 so as to be vertically slidable.
As shown in the figure, the threshing feed chain 9 extends approximately horizontally from the starting end to the outside of the threshing device 4, and the mounting cylinder portion 2 of the grain culm supply stand 20
A U-shaped locking tool 24 configured to be removably inserted and mounted across the guide bottom plate 8 and the guide bottom plate 8.
As shown in FIG. and the guide bottom plate 8 so that it can be removably attached and switched to a fixed storage position. In other words,
By setting the grain culm supply table 20 in the operating position and sliding the grain culm on the table to the side of the grain culm supply port 4a, it is also possible to manually feed the grain culm directly to the threshing feed chain 9. .

As shown in FIGS. 1 and 2, the member 18 supporting the conveyance guide rail 17 of the terminal end side conveyance device portion 7b, and the guide supply rod 1
9 is arranged so that when the grain culm supply stand 20 is in the upright and retracted position, the guide rail 17 is in the operating position with respect to the chain 15, and the guide supply rod 19 is in the operating position with respect to the threshing feed chain 9. A grain culm supply stand 20 is attached in this state, and the grain culm supply stand 20 also serves as the mounting frame for the support member 18 and the guide feed rod 19.

Incidentally, the bent portion 20b of the grain culm supply stand 20 shown in FIGS. 1 to 4 is such that the insertion length of the grain culm into the handling chamber is a predetermined length when the grain culm is fed using the grain culm supply stand 20. This is to align the tip so that the The bent portion 20b is formed in a shape that guides the grain culm from the starting end transporting device portion 7b to smoothly move to the terminating end transporting device portion 7a when the grain culm supply table 20 is in the stored state. be.
