Description

[Detailed description of the invention] This invention reduces the weight of the drive shaft 17 of the culm cutting device 3 by rationally transmitting the power of the threshing machine 1 to the culm cutting device 3 and the culm binding device 5. This aims to shorten the overall transmission path.

In conventional devices, as seen in Japanese Utility Model Application No. 52-128579 and Japanese Unexamined Patent Application Publication No. 52-30652, human power for the culm binding device 5 was performed from the side of the culm plant.

Here, in small machines, the base of the culm protrudes beyond the side wall, and in order to avoid this, the culm binding device 5 is installed.
The input shaft and the pulley at its tip protruded noticeably to the left from the side wall.

This was inconvenient because it hit uncut culms or caught objects during the harvesting and threshing process.

On the other hand, in this invention, the drive shaft 17 of the culm cutting device 3
was used to convert the output of the thresher 1 from the stock side of the culm to the tip side of the culm, and manually input it to the culm binding device 5 from the tip side of the culm.

Therefore, according to this invention, since the input to the culm binding device 5 is performed from the tip side of the culm, the input shaft and pulley do not protrude toward the root of the culm, that is, the uncut culm side of the machine. There is no possibility of scraping off uncultivated grains or causing an obstacle to transportation.

In addition, the frame of the binding device houses a transmission mechanism group that distributes and transmits power between the knot and the needle.
Since the information is input directly here, the transmission mechanism in the binding device becomes simple.

Next, a description will be given based on a drawing of a reaping and threshing machine with this invention. 1 is a threshing machine, and its foot chain 9 is mounted on a chassis having a traveling device 8 in a state along the machine traveling direction A. The culm outlet 2 has a foot chain 9.
is provided at the end of the transfer.

6 is an exhaust culm transfer device whose starting end faces the terminal end (culm opening 2) of the foot chain 9, and whose rear end faces the foot chain 9.
A transfer ceno 10 is wound and stretched so as to be inclined in plan view and extend rearward toward the tip side of the culm to be transferred.
It consists of clamping rods 11 and 12 that are forcibly pressed toward the top and bottom sides of this cheno 10 toward the chino 10.The transfer cheno IQ is configured to be capable of forward and reverse rotation, and the lower clamping rod 12 It is cut in the middle.

Reference numeral 3 designates a removal culm cutting device which is detachably installed in the machine frame at the rear end of the threshing machine 1 with the upper opening 13 facing the terminal end of the lower clamping rod 12 of the transfer cheno 10. It is horizontally suspended between both side walls 3a and 3b along the culm direction of the culm, and the gears 14 are connected to each other.
．． Drive shaft 16.1 mounted horizontally for counter-rotation via 15
7, a feed rotor 18 and a cutting blade 19 are disposed facing each other.

Power is transmitted to the culm cutting device 3 by winding and tensioning a belt 19 between an output pulley (not shown) provided on the output shaft of the threshing section and an input pulley 18a provided on the drive shaft 17. It is configured to be carried out from the stock side of the culm.

Reference numeral 5 denotes a discharge culm binding device, which is detachably installed on the rear machine frame of the discharge culm cutting device 30 in the direction of movement of the machine, with the binding passage 20 facing the terminal end of the clamping rod 11 on the upper side of the transfer chino 10. Transmission shafts 22 and 23 protrude vertically across the binding passage 20 from a binding frame 21 that houses a transmission mechanism, and are each fitted with a binding mechanism 4 such as a knot 24 and a needle 25.

In order to install the above-mentioned binding device 5 on the back side of the culm cutting device 3, the culm binding device 5 is attached to the surface of the side wall frame 3b of the culm tip side portion of the culm cutting device 3 at a position facing the foot chain 9. and the outer surface of the binding frame 21 are positioned substantially on the same line in plan view.

26 is a packer, 27 is a discharge rod, and 32 is a T-protrusion clutch.

Reference numeral 7 denotes a power transmission mechanism, which is interposed between the tip side wall frame 3b surface of the culm cutting device 3 and the outer surface of the binding frame 21, and is connected to a pulley 2 provided at the protruding end of the drive shaft 17.
8 and a pulley 30 provided on a drive shaft 29 that drives a transmission mechanism for operating the binding mechanism 4 built into the binding frame 21.
The rotational power from is transmitted to the binding frame 21 via the belt 31.
It is configured to transmit information to the internal transmission mechanism.

In the upper configuration, the work is started by driving the prime mover to rotate each rotating part of the machine body, but if we were to cut the culm now, if we rotate the transfer chino 10 in the forward direction (in the direction of the arrow), The threshed culm from the foot chain 9 passes through the culm discharge port 2 and is transferred to the lower side of the transfer chain 10 and the clamping rod 12.
The cutting blade 19 and the feed rotor 18 rotate in opposite directions to cut the cutting blade 19 into short pieces.

Next, when binding the waste culm in an uncut state, when the transfer cheno 10 is rotated in the opposite direction (in the direction of the arrow), the waste culm passes through the waste culm opening 2 and connects to the upper side of the transfer cinch and the clamping rod. 11,
It was grabbed and transported to the rear.

This culm transmits the rotational power of the rotating shaft 17 of the culm cutting device 3 to the bells 1 to 31. When the packer 26, which is operated by the transmission mechanism in the binding frame 1 and is operated via the transmission shafts 22 and 23, is drawn into the binding passage 20 and focused by a certain amount, T
The protrusion clutch 32 is engaged, the needle 25 and the knot 2
The focusing culm is bundled by the operation of 4, and then the discharge rod 2
7, it is ejected from the aircraft.

A belt 31 that transmits power to the culm binding device 5 is wound and stretched between the drive shaft 29 of the culm binding device 4 and the drive shaft 17 of the culm cutting device 3 located at the closest position. Since the tension of the belt 31 is always maintained at an appropriate level, the power can be reliably transmitted to the binding device 5 with an appropriate belt tension without causing the belt or the like to slip because the transmission distance is too long, unlike in the conventional case. The binding device 5 can be operated accurately without any bundling errors.

In addition, since the outer surface of the binding frame 21 and the side wall frame 3b of the culm cutting device 3 are positioned approximately on the same line in plan view, the center between the two pulleys 28, 30 when installing each pulley 28, 30 is The position can be easily aligned and the rotation of the belt 31 can be stabilized.

In short, this invention is constructed as described in the claims for utility model registration, so that the output of the threshing machine 1 on the stock side of the culm is connected to the drive shaft 1 of the culm cutting device 3.
7 to the tip side of the culm, and introduced into the culm binding device 5 from the tip side of the culm.

Therefore, in a device in which the exhaust culm cutting device 3 and the exhaust culm binding device 5 are arranged in front and behind each other, the special P
Since there is no TO axis, the transmission configuration can be simplified.
The overall configuration can be made smaller, and furthermore, unlike conventional methods, the input to the culm bundling device is not performed from the culm stock side, so this input device can be placed outside the culm stock side. It does not protrude to the side and pose an obstacle or danger, and it is rational because it is immediately input into the frame 21.
