DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chain lever for a mobile agricultural machine.

An object of the present invention is to provide a mobile agricultural machine in which the steering handle can be adjusted up and down, by configuring the chain lever to be able to move up and down in accordance with the up and down adjustment of the steering handle, so that the steering wheel can be constantly operated. To provide a chain lever for a mobile agricultural machine with good operability, which can maintain the relative position of a steering handle and a chain lever at a predetermined position.

In order to achieve the above object, the present invention provides a chain guide 3 integrally with a steering handle 1 which is configured to be vertically adjustable.
A chain lever 7 is provided to protrude from a guide groove 5 provided on the same side as the steering handle 1, and the chain lever 7 is vertically movably connected to a chain rod 13 extending vertically in front of the guide groove 5. This is what I did.

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

1 and 2 are a partially omitted overall side view and an overall plan view of the reaping gear, which is composed of a traveling section 15 and a reaping binding section 17.

The running section 15 is configured as follows. In other words, 19 is a prime mover, and an engine frame 23 extends rearward from the transmission case 21.
mounted on top. The mission case 21
A lower hitch 27 having an engaging portion 25 is protruded from the lower front surface of the holder. Further, a support bracket 29 is provided above the mission case 21, and an upper engagement member 31 is horizontally suspended from the front portion of the support bracket 29. A transmission case 33 houses a power transmission device (not shown) such as a belt transmission mechanism for transmitting the power of the prime mover 19 to the transmission case 21. A pair of left and right wheels 35 are mounted on a pair of left and right axles 37 provided at the end of a power transmission device (not shown) such as a gear transmission mechanism installed in the transmission case 21. 39 is the third handle frame
As shown in the figure, it is attached via a shaft 41 to a support bracket 29 provided above the mission case 21 so as to be movable up and down. The steering handle 1 extends rearward to the handle frame 39, and a chain guide 3 for guiding the chain lever 7 is integrally provided. A positioning hole 43 for fixing the handle frame 39 is bored in the support bracket 29.
In addition, the handle frame 39 has a plurality of pin holes 45, 45, . It is perforated. Then, move the steering handle 1 up and down to move the handle frame 39 up and down, make any pin hole 45 correspond to the positioning hole 43, and insert the fixing pin 47 into the pin hole 45 and the positioning hole 43. Thus, the handle frame 39 is fixed to the support bracket 29, and the height position of the steering handle 1 is adjusted. As shown in FIG. 4, the chain lever 7 is provided with a grip portion at the rear end thereof protruding from a guide groove 5 formed in the chain guide 3 toward the same rear side as the steering handle 1. Further, a connecting member 9 formed in a bifurcated shape is provided at the tip of the chain lever 7, as shown in FIGS. , the upper end of the chain rod 13 on the front side of the chain guide 3 in which the guide groove 5 is formed is connected to the chain lever 7.
is configured to be movable up and down using the connector 11 as a fulcrum. The chain rod 13 is rotatably supported by a mission case 21, and its lower end is connected to a chain mechanism (not shown) built into the mission case 21.

A reaping output box 49 rotatably supports a reaping output shaft 51 that is interlocked with a transmission device (not shown) such as a bevel gear.

The reaping binding section 17 is configured as follows. That is, 53 is a reaping frame, and a binding frame 55 is connected to the right side (upper side in FIG. 2) of the reaping frame 53, and a weeding rod support member 57 is connected to the left side (lower side in FIG. 2). are doing. In addition, a lower engaging member 59 is provided at the lower part of the back surface of the reaping frame 53 to detachably engage with the engaging part 25 of the lower hitch 27 provided on the side of the traveling part 15, and at the upper part, A hook 61 is provided to detachably engage the upper engagement member 31 on the side. Reference numeral 63 denotes a reaping input box provided in front of the reaping frame 53, which rotatably supports a reaping input shaft 65 which is interlocked and connected to a transmission device (not shown) such as a bevel gear. The reaping input shaft 65 is operatively connected to the reaping output shaft 51 of the reaping output box 49 of the traveling section 15 via a connecting member 67.

69 is a plurality of weeding devices, each of which has a weeding body 7;
1 and a weeding rod 73, which is provided to protrude from the above and is used to divide and guide the planted stem and culm. Reference numerals 75a and 75b denote a pair of left and right pulling devices, which are arranged in a backward-sloping manner behind the weed cutting body 71, and are used to pull up the planted stem culms that have been separated by the weed cutting device 69. Reference numeral 77 denotes a reaping device, which is provided at the rear lower part of the pulling devices 75a, 75b, and cuts the stem culm pulled up by the pulling devices 75a, 75b from its root portion. 7
Denoted at 9a and 79b are a pair of left and right star foils, which scrape the base of the reaped stem culm that has been reaped by the reaping device 77. Reference numerals 81a and 81b denote a pair of upper and lower transverse feed devices, which are provided at the rear upper part of the reaping device 77 and convey the reaped stem culm cut by the reaping device 77 to one side of the machine body.
Reference numeral 83 denotes a binding device, which connects the horizontal feeding devices 81a and 81.
lateral feed devices 81a, 81b
The stem culms transported by the culms are collected and tied, and then released into the field.

In the above configuration, in order to adjust the vertical height position of the steering handle 1, after removing the fixing pin 47 inserted through the pin hole 45 and the positioning hole 43, the steering handle 1 is attached to the handle frame with the shaft 41 as a fulcrum. 3
9, rotate the fixing pin 47 upward or downward through the handle frame 39, align any pin hole 45 of the handle frame 39 with the positioning hole 43 of the support bracket 29, and insert the fixing pin 47 through the pin hole 45 and the positioning hole 43 again. and support the handle frame 39 with the bracket 2
9, the steering handle 1 can be fixed at any height position.

As the steering handle 1 moves up and down, the chain guide 3 moves up and down as a unit, and the chain guide 3 pushes the chain lever 7 upward or downward. It moves up and down using the connecting tool 11 as a fulcrum to follow the up and down movement of the steering handle 1. Therefore, even when the height position of the steering handle 1 is adjusted up or down, the relative position between the steering handle 1 and the chain lever 7 does not change and always maintains a predetermined relative position, which improves operability. This means that you can get a good chain lever.

The present invention provides a steering handle configured to be vertically adjustable, with a chain guide integrally provided, and a chain lever protruding from a guide groove provided in the chain guide to the same side as the steering handle,
The chain lever is connected to the chain rod extending vertically in front of the guide groove so as to be movable up and down, so when the steering handle is adjusted up and down, the chain lever moves up and down with respect to the chain rod via the guide groove. can be done. Therefore, the trouble of having to adjust the position of the chain lever in conjunction with adjusting the position of the steering handle is eliminated, and the relative position of the steering handle and chain lever can always be maintained at a predetermined position simply by adjusting the steering handle. The chain rod can be operated from that position, greatly improving operability.

Note that this invention is not limited to the above-mentioned embodiments, and the invention can be implemented in modes other than the above-mentioned embodiments.

Further, although reference numerals are written in the claims section for convenience of symmetry with the drawings, the numerals do not limit the technical scope of the present invention.
