Description

[Detailed Description of the Invention] The present invention is configured such that the vertical conveyance ch 7 that inherits and supplies the culm from the reaping section to the threshing section is configured to change the inclination and adjust the length of the culm by operating a control lever. This invention relates to improvement of the shell culm conveyance and supply section.

In the above-mentioned shell culm conveying and supplying section, when the vertical conveyance chain 7 is adjusted to change the inclination, the relative position of the conveying end part is changed in the inward/outward direction with respect to the foot chain starting end, and the holding position of the delivery shell culm is changed. Since it is advantageous to maintain good transfer performance, this type of structure has been common in the past.

However, with this configuration, when the grain culm to be fed is a very long culm or a long culm, when the vertical conveyance che 7 is adjusted to change the inclination so that the grain culm is fed to the threshing section at an appropriate feeding depth, The transfer terminal side of the vertical transfer chain 7 extends outward from the outside of the foot chain, that is, from the outside of the machine.
Hook the uncut long culms that are planted adjacent to the machine (the uncut culms are also planted with long plants because the husk feeding the threshing section must be adjusted to a longer culm). It has the disadvantage of causing problems such as shedding of grains and disturbing the planting posture.

The present invention has been implemented in view of the actual situation of the conventional device as described above, and has a structure in which the transfer end side of the vertical conveyance chain 7 can be changed in relative position in the inside and outside directions with respect to the start end of the foot chain, and the length can be adjusted. However, even if the shell culm is extremely long, the amount of outward protrusion of the vertical conveyance check 7 can be kept relatively small and adjustments can be made for the extremely long culm, and the above-mentioned problems will not occur. It is provided in this way.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the combine harvester. Above the waist crawler 2 running body 7 are a handling trunk 8, a supply port 9, a foot chain 3, and a culm 1.
0. Threshing section 2 with straw removal cheno 11 etc. in the same manner as the conventional structure
is mounted, but the starting end 3a of the foot chain 3 is configured to protrude forward from the starting end of the lower culm 10.

A reaping section C is installed in the front of the machine body in front of the threshing section 2, and the reaping section C has a grass dividing plate 12, a pulling body 13,
The cutting blade 14 and the lower conveyor 15 are equipped in the same manner as in the conventional structure, and the lower conveyor 15 inherits the culm side of the culm 1 from the vertical position and raises it to a horizontal position while moving the foot from the terminal end 4a. A vertical conveyance check 74 is obliquely installed at the starting end 3a of the chain 3, and a clamping rod 16 is attached to the check 74.
Configure by setting them in parallel.

In addition, a transmission case 17 connected to the vicinity of the terminal end 4a of the vertical conveyance check 74 supports the vertical conveyance check 74 and the clamping rod 16, and enables drive transmission to the transmission case 17.
7 and a lower gear case 1B are interlocked and connected by a transmission pipe 19, and a transmission case 17 is rotatably constructed around a fulcrum C to the end of a fixed power transmission case 20 that transmits power to each part of the reaping section C. Then, the vertical conveyance check 74 and the clamping rod 1
6 can be rotated around the fulcrum O, and when the inclination is changed while rotating according to the length of the culm, the terminal end 4a of the vertical conveying chain 74 extending below the starting end 3a of the foot chain 3 is connected to the supply shell culm 1. The structure is configured such that the terminal moves near and far from the starting end 3a along the longitudinal direction, but when the terminal end 4a moves away from the starting end 3a due to rotation around the fulcrum O, the terminal end 4a falls downward. Become.

Reference numeral 5 designates an operating lever, and the base of the operating lever 5, which is long and bent, is provided so as to be rotatable about a fixed support shaft 21, and a support guide 22 fixed to the body has a guide groove 23 through which the operating lever 5 is inserted. At the same time, a plurality of stepped engagement grooves 23' are formed along the guide groove 23 to connect the middle part of the operating lever 5 and the lower part of the vertical conveyance check 74 to the connecting rod 24.
When the operating lever 5 is moved along the guide groove 23, the vertical conveyance check 74 and the pinning rod 16 are rotated about the fulcrum O by the interlocking connection of the connecting rod 24, and the inclination can be changed.

Further, a support rod 26 is slidably inserted into the guide 25 rotatably attached to the body, one end of the support rod 26 is connected to the middle part of the operating lever 5, and the other end of the support rod 26 is connected to the middle part of the operating lever 5. A support 6 is installed in series to support the culm body of the husk 1 from below and guide it to the threshing section 2 side. While maintaining the attitude of approaching the part 3a downward, when adjusting the long culm, it can move outward and protrude upward relative to the vertical conveying chain terminal end part 4a, which extends outward and downward from the lower part of the foot chain starting end part 3a. Configure it as follows.

Therefore, during combine harvesting work, the culm 1 cut by the cutting blade 14 is conveyed by the lower conveyor 15 while holding the culm base side, and when it is transferred to the vertical conveyance chair 74 and the clamping rod 16, the third As shown in the figure, the culm side is raised from the vertical state to the horizontal state, and the culm side is transferred from the terminal end 4a of the vertical conveyance chain 74 to the start end 3a of the foot chain 3, and the head side is fed to the supply port 9. The grains are fed and supplied to the threshing section 2.

In this case, the support body 6 approaching the terminal end 4a of the vertical conveyance check 74 supports and guides the culm body of the culm 1 from below, while making the culm 1 horizontal and performing feeding guidance. .

Incidentally, depending on the length of the culm 1 or the short culm, it is possible to feed the husk to the threshing section 2 at the same depth, but in that case, while rotating the operating lever 5 around the support shaft 21, 22, the vertical conveyance check 74 rotates around the fulcrum O and changes its inclination, and at the same time, the terminal end 4a of the vertical conveyance check 74 moves as shown in FIGS. 6 to 8. As the culm becomes longer, the culm side is moved further away from the end 3a so that the same handling depth can be supplied.

In that case, the support body 6 that moves following the movement of the terminal end 4a supports the culm from below and guides the culm so as to keep it stretched so that it does not accumulate downward, and feeds it into the foot chain 3. As shown in FIG.
The support body 6 approaching the culm can be guided and fed to the starting end 3a while sufficiently lifting the culm to stretch the culm.

In this way, the present invention raises the culm 1 from an upright state to a horizontal state, and moves the vertical conveyance check 74 to the starting end 3a of the foot chain 3 of the threshing section 2 from the terminal end 4a to the culm base side by operating the operating lever 5. In the culm conveying and supplying section of the combine, which is configured to be able to rotate around the fulcrum O and change the inclination for adjusting the length of the culm, the terminal end 4 of the vertical conveying check 74
A support 6, which is located closer to the tip of the culm and can support and guide the culm from below, is placed from the terminal end 4a of the vertical conveyance check 74 toward the tip of the culm from below. A support 6 that can support and guide is provided, and while maintaining a posture close to the foot chain starting end 3a, the support 6 extends outward and downward from the bottom of the foot chain starting end 3a during long culm adjustment. Since the vertical conveying chain 74 is configured to be movable and operable in conjunction with the operation of the operating lever 5 so as to move outwardly and upwardly protrude with respect to the end portion of the vertical conveying chain that moves, the vertical conveying chain 74
The culm body of the shell culm 1 which is transferred and supplied from the terminal end 4a to the starting end 3a of the foot chain 3 can be supported from below, and the transfer can be guided well while keeping the tension so that it does not sag. Since it rotates around the fulcrum O, the culm is lifted up by the support 6 even if it moves downward without moving away from the terminal end 4a of the vertical conveyance chain 74 in the horizontal direction. Supports that can reliably support and guide, that is, even if the conveying shell culm is a long culm and adjustments are made to correspond to the long culm, the support moves outwardly and upwardly as the vertical conveying check 7 moves. Due to the presence of the body 6, the stock base of the culm, which increases the outward protrusion, is curved in an arcuate shape and the actual protrusion dimension is reduced. Therefore, the vertical conveyance device can be moved for a long time without protruding outward extremely. While the culm is being adjusted, the culm is reliably delivered by being pushed toward the starting end of the foot chain by the support 6, resulting in good adjustment without causing damage to the adjacent uncut culm. Can be supplied.
