Abstract

PURPOSE:To improve the strength and endurance of a straw carrying device by slidably support a continuous lever for constituting a straw carrying device in the threshing frame. CONSTITUTION:A straw which is subjected to threshing treatment and received from the end part of a holding and carrying device 12 to a straw carrying device 11 is carried in the final end part direction held between a guide lever 10 and a straw chain 8. Then the straw is fed from the final end part of a straw carrying device to a straw treating working machine 15. In this case, the straw carrying device 11 is moved and controlled in the direction of the arrow A or reverse direction thereof in order to satisfactorily feed straw to the straw treating machine 15 independently from the length of straw. In this case, since a coupling lever 6 is laterally moved while sliding the upside of threshing frame, even the heavy straw carrying device 11 is not hung below. Then the straw carrying device 11 can be safely controlled without contact, since lower face of the intermediate part of a holder has hollow shape even when the upper side is swelled because of a discharge dust fan 16 internally provided in the machine body 3.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a straw conveying device in a threshing machine.

[Prior art]

In order to change the straw discharge position of the conventional straw conveying device of this type of threshing machine, the terminal end of the straw conveying device can be moved to the left or right (
There was one that was configured to change its position in the culm direction).

[Problem to be solved by the invention]

In the above-mentioned conventional type, in order to make the structure movable and adjustable in the culm direction, the overall structure was required to be lightweight, which inevitably led to insufficient strength and durability.

In addition, when the straw removal conveying device is used for a long period of time while performing the movement wI section, there is a drawback that the portion far from the rotational fulcrum deforms downward due to its weight.

In contrast, the present invention attempts to solve the problems of the conventional type by allowing the connecting rods forming the framework of the straw removal conveying device to be freely slidably supported by the threshing frame.

[Means to solve the problem]

This invention aims to solve the above-mentioned problems.

The following technical measures will be taken. In other words, one end is connected to the handling room 1.
A threshing frame 4, which is fixed to the outlet side plate 2 of the machine and whose other end is attached to the rear of the machine body 3, is installed above the straw conveyance passage 5, and the straw conveyance passage 5 has a chenorail 7 provided on one side of the connecting rod 6. A straw removal conveyor 11 is provided, which is composed of a straw removal cheno 8 guided and supported by a guide rod 10 supported by a holder 9 attached to the other side of the connecting rod 6. The straw discharging conveyor 11 is provided with an adjustment device for selecting the straw discharging position. 14 is a straw conveying device in a threshing machine, in which the connecting rod 6 is movably supported while sliding on the threshing frame 4.

[Action/Effect]

The waste straw that has been threshed and passed from the terminal end of the clamping conveyance device 12 to the waste straw transfer device 11 is conveyed toward the terminal end while being held between the guide rod 10 and the straw waste cheno 8. The waste straw is then supplied to the straw processing machine 15 from the terminal end of the waste straw transport device.In this case, the waste straw transport device 11 supplies the waste straw to the straw processing machine 15 regardless of the length of the straw. For proper feeding, adjust the movement in the direction of arrow A in FIG. 2 or in the opposite direction.

That is, the straw transporting device 11 operates the adjusting device 14 to adjust its movement using the vertical shaft 13 as a fulcrum in the direction of arrow A when the straw is long, and in the opposite direction of arrow A when the straw is short.

In this case, since the connecting rod 6 moves from side to side while sliding on the threshing frame 4, even the heavy straw removal conveying device 11 does not sag downward.

As shown in the embodiment shown in FIG. 3, the straw removal conveying device 11 has a concave lower surface in the middle portion of the holder 9 even though the upper side is bulged due to the dust removal fan 16 built into the machine body 3. Because of this, adjustments can be made safely without contact.

As described above, this invention has a configuration in which the straw removal conveying device is supported by the threshing frame via the connecting rod and can slide from side to side. can also be adjusted reliably.

Moreover, since the straw removal conveying device can move from side to side while being supported by the threshing frame as a whole, it has the feature that there is almost no risk of it sagging downward or being deformed.

〔Example〕

The threshing frame 4 has one end attached to the outlet side plate 2 of the handling chamber 1, the other end attached to the rear part of the machine body 3, and passes above the straw conveyance passage 5 to ensure the strength of the machine body.

The straw removal conveyance device 11 is composed of a straw removal chenograph 8 and a guide rod 10, and is located in the above-mentioned straw removal conveyance path 5, with its starting end facing the pinching transfer device 12, and its terminal end facing the straw processing work machine. 15
It is composed with a focus on

The specific structure of this straw removal conveying device 11 is such that a holder 9 with a concave lower surface is attached to one side of a connecting rod 6, and a chenorail 7 is attached to the other side.

Reference numeral 16 denotes a dust removal fan, which is installed below the holder 9 described above.

A guide rod 10 is attached to the holder 9 under tension with a spring, and is attached to the chenor rail 7 so as to be able to guide the straw discharging chenor 8.

Note that 17 indicates a straw removal belt, which is attached to the connecting rod 6 on the tip side of the straw removal from the straw removal cheno 8.

The connecting rod 6 is slidably supported above the threshing frame 4.

The straw removal conveying device 11 has a configuration in which rotational power is transmitted by a gear box 18 connected to its starting end, and can be rotated via a vertical shaft 13 of the gear box 18.

The adjustment device 14 includes a rotary arm 20 . connected to a motor 19 .
Lot 21, swinging rod 22. It is composed of a continuous rod 23 and is connected to the straw removal conveying device 11.

In addition, the straw processing work machine 15 is a straw cutting device in the case of the embodiment.

When working with the above structure, the straw removal conveying device 11 is adjusted in movement in order to reliably supply the straw to the cutting device regardless of its length.

That is, when the straw transporting device 11 drives the motor 19, the rotating arm 20, the rod 21, the swinging rod 22, and the connecting rod 23 are activated.
Can be adjusted via.

In this case, when the straw transporting device 11 is adjusted to move in the direction of arrow A, the motor 19 is rotated in the forward direction, and when it is moved in the opposite direction of arrow A, the motor 19 is linearly moved in the reverse direction. Rotate using the fulcrum as a fulcrum.

During such adjustment, the connecting rod 6 is always supported on the threshing frame 4 and can slide.
