Description

[Detailed description of the invention] The present invention is typified by a waste straw binding device installed in a combine harvester, and more specifically, it is pressure-sensitive activated when the amount of materials to be bundled in the focusing and binding space reaches a set amount. The present invention relates to an agricultural tying device that is provided with a sensing door and a clutch mechanism that interlocks a transmission mechanism for a string supply needle, a knot bill, and a string holder with a drive shaft based on the pressure-sensitive operation of the sensing door.

In conventional agricultural binding devices of this type, the string supply needle, knot bill, and string holder are configured to operate in conjunction with the drive shaft via a clutch mechanism. The needle, bill, and holder cannot be operated unless the drive shaft is rotated, so by operating the needle and string holder, the winding string can be fed along a predetermined path to the needle. When initially setting the string to hold the end of the string in the string holder, for safety reasons, with the engine stopped, that is, the drive shaft stopped, manually operate the sensing door to engage and operate the clutch mechanism, and then, when working alone, Start the engine by tying the end of the cord passed through the needle to the fixed part, or if two people are working, one person should hold the end of the cord in his hand while the other person starts the engine. When the engine starts, the needle and string holder operate and the end of the string is held in the string holder.For safety reasons, stop the engine and cut off the excess string end protruding from the string holder. A number of steps were required.

Therefore, when using conventional agricultural tying devices, two workers are required to initially set the string, or the worker must move back and forth between the tying device position and the engine starting position. like,
The drawback was that the initial setting of the string was difficult.

The purpose of the present invention is to overcome these conventional drawbacks.

The characteristic structure of the agricultural binding device according to the present invention, which was taken to achieve the above object, is that an operating section is provided on the lower side of the transmission of the clutch mechanism, which allows the transmission mechanism to be operated by manual operation from outside the binding device. At the point.

The operation of the present invention having such a characteristic configuration is as follows.

Without operating the drive shaft, that is, the engine, the needle, bill, and holder can be operated artificially by operating the operating section while the clutch is engaged and operated by operating the sensing door.

Since the operating section is provided on the lower side of the clutch mechanism's transmission, there is no unnecessary manual operation until the clutch mechanism is activated, unlike when it is installed on the upper side of the clutch mechanism's transmission. The transmission mechanism can now be operated.

Therefore, according to the present invention, when initially setting the string, it is only necessary to operate the sensing door and the operating section at the binding device position, so that the string can be easily, quickly, and safely operated by one person. This has the effect of increasing the versatility of the device by making it possible to initially set items such as radish, and to manually bind items other than the objects to be bound, such as radishes, simply and easily.

Hereinafter, embodiments of the configuration of the present invention will be described based on the drawings.

This is a waste straw binding device that is detachable from the rear part of the threshing device 1 in a combine harvester, and is a collecting and binding space 3 to which waste straw in a sideways posture is supplied from the threshing device 1 via the chain 2.
A constantly operating type scraper that scrapes waste straw 4
When the amount of waste straw in the space 3 reaches a set amount, the sensing door 5 swings pressure-sensitively against the biasing force of the spring, and also swings to open the exit of the space 3 when the bundled straw is released. and a binding mechanism that ties and releases the focused straw.

The binding mechanism is of a known structure comprising a string supply needle 6, a knot bill 7 and a string holder 8.

Between the input shaft 10 of the transmission mechanism 9 to the needle 6, bill 7, and holder 8 and the drive shaft 11 driven by the engine, the input A clutch mechanism 12 of a known structure is interposed for interlocking the input shaft 10 with the drive shaft 11 in a state in which the shaft 10 is unlocked and the input shaft 10 is pushed back by the drive shaft 11.
That is, the input shaft 10 becomes rotatable when the clutch mechanism 12 is engaged through the sensing door 5 when the drive shaft 11 is stopped.

Thus, an operating section 13 is provided which allows the transmission mechanism 9 to be actuated by an external manual operation.

The operation section 13 has an operation shaft 15 interlocked with the drive shaft 11 via a pair of bevel gears 14, 14, and a rotary operation handle 16 that can be attached to the different diameter end of the operation shaft 15 in a non-rotating state. established and configured.

17 connects the rotary operating handle 16 to the operating shaft 15
18 is a winding string, and 19 and 20 are a string brake and a slack-removal rod provided in the string supply path from the winding string 18 to the needle 6.

According to the configuration of the above embodiment, even if the drive shaft 11 is not actuated, the sensing door 5 can be artificially pressure-sensitively swung and the rotary operation handle 16 can be operated with the clutch mechanism 12 unlocked. Binding can be performed by operating the transmission mechanism 9, that is, the needle 6, bill 7, and holder 8. Therefore, by adopting this manual tying method when initially setting the string, the tying can be done without starting the engine.
The strings can be set by one person at the binding device position, and can be tied even when the binding device is removed from the threshing device 1.

As shown by the imaginary line in FIG. 3, the operating section 13 may be configured by providing a rotary operating handle 16 that is detachably attached to the end of the drive shaft 11.
