Description

[Detailed description of the invention] [Industrial application field] The present invention is an ejector that discharges bundles of culms bound together by knocks attached to combine harvesters, harvesters, etc. into the field in a predetermined posture. This invention relates to a culm bundle release device.

[Prior art]

The tips of the threshed culm bundles discharged from the knock are held in the discharge position of the knock, which is attached to the threshing culm discharge position of a combine harvester, etc. and is configured to bundle the threshed culms into a predetermined size. Equipped with a culm release device that transports the culm bundle with the base side hanging down and releases it from the conveying end, and allows the culm bundle to stand upright in the field to promote drying of the culm bundle in the sun. A device has been proposed by the applicant and others.

In this discharged culm bundle release device, since the base side of the discharged culm bundle suspended by the discharge device is left in a free state,
Shaking due to the vibrations of combine harvesters, knots, and other machines,
There was a problem in that the posture when released was inconsistent and it was not possible to reliably stand it in the field.

[Problems to be solved by the invention] Therefore, the present invention discharges the waste culm bundles transferred by the above-mentioned waste culm bundle discharging device in such a way that it does not shake due to vibration of the machine, etc., and releases the waste culm bundles to the field. It is an object of the present invention to provide a culm bundle discharge device that can be reliably erected.

[Means of trying to solve the problem]

For this purpose, the present invention clamps the tip side of the discharged culm bundle discharged from the knock at the discharge position of the knock, hangs the base bundle in a free state, and diagonally backwards toward the terminal end. 5. Provide a discharge device for discharging culm bundles for upward transport.5. Below the transfer path of the discharged culm bundle, the culm bundle is transferred in an almost upright position by the discharged culm bundle, and the culm side is controlled to be in an almost upright position by holding down the base side of the discharged culm bundle, and the discharged culm bundle is controlled to be in an almost upright position. This apparatus is characterized by being provided with a posture control body that transports the discharged culm bundle at a transport speed that is approximately equal to the transport speed of the bundle discharge device.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, reference numeral 1 is a well-known knock attached to the threshing culm discharge device of a combine harvester, and the knock 1 is placed at the culm bundle discharge position by clamping the tips of the culm bundles and freeing the stock side. A well-known tip conveying mechanism 2 is provided which suspends the tip (in an upright position), conveys it obliquely upward on the rear side of the fuselage, and discharges it.

As shown in FIG. 2, this tip conveyance mechanism 2 consists of an endless conveyance belt 2a and a clamping rod 2b provided opposite the conveyance surface of the conveyance belt 2a, and the conveyance belt 2a constantly rotates. Rotating power is received from the knocker shaft 3 of the knock 1 via the chain transmission system 4, and the knock 1 rotates in a predetermined direction.

In addition, on the lower side of the tip transport mechanism 2, the stock side of the discarded culm bundle, which is transferred with the stock side hanging down in an almost upright state, is clamped (locked) by the top transport mechanism 2. ) and transported at a transport speed approximately equal to the transport speed of the tip transport mechanism 2,
A plant base conveyance mechanism 5 is provided which controls the conveyance posture of the discharged culm bundle by transporting the discharged culm bundle while maintaining it in a substantially upright state.

The stock base conveyance mechanism 5 includes an endless wide conveyance belt 5a, which faces the conveyance surface of the conveyance belt 5a, has one end fixed to the knock 1, and extends the other end along the conveyance belt 5a. The conveying belt 5a receives rotational power from the transmission system of the conveying belt 2a, and rotates in a predetermined direction.
- The culm bundles are moved in the same direction at approximately the same speed (see Figure 2). are tied closer to the tip side than the usual binding position (mostly on the plant side) and are discharged.

The tip of the culm bundle discharged from the knock 1 is fed to the starting end of the tip conveying mechanism 2, as shown in FIG. As shown in FIG. 1C, the stock side is allowed to hang down in an almost upright position.

The starting end of the stock head transport mechanism 5 faces the position where the stock head side is hanging down, and the discarded culm bundle is transferred between the ear tip and the stock head by the head transport mechanism 2 and the stock head. It is held between the transport mechanism 5,
The discharged culm bundle is conveyed to the rear side of the machine body while being held in an almost upright state, and is released from the conveyance ends of both conveyance mechanisms 2' and 5, and falls onto the field, where it is erected.

During the conveyance process of the discarded culm bundle, for example, even if the combine tilts to the left or right, or even if vibrations from the combine harvester or the knock 1 are transmitted to the discarded culm bundle, the discarded culm bundle will not move between the tip conveying mechanism 2 and the stock. Since it is held and transported by the base transport mechanism 5, it is not affected by it and does not sway.

Further, as is clear from the drawing, the tip transport mechanism 2 is sequentially raised obliquely upward, and along with this raising operation, the stock base clamping position of the stock base transport mechanism 5 is also sequentially raised, and the discarded culm bundle is removed during the transport process. The tip of the stock base never comes into contact with the field.

Further, the discharge timing of the discharged culm bundles of the ear tip conveyance mechanism 2 and the stock base conveyance mechanism 5 is set so that the ear tip conveyance mechanism 2 is slightly slower.

The bundle of culms erected in the field is tied at the tip side, and the plant base side is spread out, so it is stably maintained in an almost upright position, and the plant base side, which has a high moisture content, has good ventilation. This promotes natural drying due to sunlight, wind, etc.

[Effect of idea]

As explained above, according to the discharging culm bundle discharging device of the present invention, the tip side is held by the discharging culm bundle discharging device, the plant base side is suspended in a free state (in an upright state), and the plant is tilted backward and diagonally upward. For this purpose, we installed a posture control body that holds down the base side of the discharged culm bundle to be conveyed so that the discharged culm bundle is in an almost upright position. The discarded culm bundles can be transported while being held in an almost upright position, and even if the machine body tilts or vibrates, the discarded culm bundles can be transported backwards and upwards without being shaken by tilting or vibrations of the machine and are released. The stem side of the plant is transferred without touching the ground and released into the field in an almost upright position, so that it can be reliably placed in the field, and the subsequent natural drying of the shed culm bundle is promoted.
