Description

[Detailed description of the invention] The present invention allows the planting device to be detached from the main traveling machine via a drive elevating mechanism. In order to avoid inconveniences such as damage or deformation of the planting mechanism caused by the machine stopping in the mud and moving the aircraft in that state, the planting mechanism is moved to the ground levitation setting position based on the cutting operation. A fixed-position stopping clutch that can automatically stop is used to prevent seedlings from being damaged or deformed by biting into stones, etc., and when a load above a certain level is applied to the planting claws. Regarding a rice transplanter that is equipped with a safety clutch that automatically cuts off power transmission, its purpose is to automatically stop the operating part of the above-mentioned running machine at a set position, similar to the planting device. The aim is to provide something useful when applying it to other agricultural machinery such as a transplanter, in other words, when making the running machine of a rice transplanter, which was a dedicated machine, more versatile. .

First, an embodiment of the present invention will be explained based on the drawings.While the inclined seedling platform 7 is reciprocated in the direction of lateral force, the planter is circulated between the seedling take-out port and the mud surface leveled by the float 9. For planting with 8 groups of claws, the mechanism 4 is activated, and each time the seedling platform 7 is located at the end of its moving path, the placed seedlings are fed in a fixed amount to the seedling take-out port side. Accordingly, in the 5-row planting method, which is configured to take out the placed seedlings in unit quantities from the lower end side and plant them, the device 1 is detached from the traveling machine 2 via the drive lifting mechanism 3. It is possible to connect O
This, the transmission system to the planting device 1 is capable of automatically stopping the planting device 1 and the planting mechanism 4, that is, the group of claws 8 are at the ground floating position based on the cutting operation. A fixed position stop clutch 5 and a safety clutch 6, which operates to automatically cut off transmission when a load above a certain level is applied during activation, are interposed with the safety clutch 6 located on the upper side of the transmission. In this riding rice transplanter, both clutches 5.
6 is installed in the transmission system l on the side of the main vehicle 2 for traveling.

The transmission system for the planting device 1 is such that the output shaft 12 of the gear type three-speed transmission that is linked to the prime mover 10 and the intermediate shaft 13 are interlocked via the safety clutch 6. The shaft 13 and the output shaft 14 of this machine are interlocked via the fixed position stop clutch 5, and the output shaft 14 of this machine and the input shaft 15 of the planting device 1 are connected with a universal joint 16 at both ends thereof. .1
They are configured to be interlocked via a transmission shaft 17 having a diameter of 6.

The fixed position stop clutch 5 includes a spring 20 that operates and biases a movable clutch piece 18 attached to the output shaft 14 side of the machine to engage a fixed clutch piece 19 attached to the intermediate shaft 13 side, and 2 (An arm 23 is provided to operate the movable clutch piece 18 by operating a control lever 22 provided near the attached driver's seat 21, and the movable clutch piece 18 corresponds to the ground floating position of the pawl 8. The cam mechanism 24 allows the movable clutch piece 18 to disengage only when the movable clutch piece 18 is in the rotating position.
and the fixing part.

The safety clutch 6 is provided with a spring 11 that biases the movable clutch piece 26 on the speed change output shaft 12 side, among the clutch pieces 26 and 27 engaged and interlocked via a group of pawls 25, to move in the engagement interlocking direction. When a load on a fixed point is applied, the movable clutch piece 26 is caused to slip with respect to the fixed clutch piece 27 against the spring 11.

According to the rice transplanter having the above configuration, planting is carried out when a transplanter or the like is connected instead of the device 1, and the fixed position stop clutch 5 on the machine 2 side.
By operating the , the connected transplanter, etc. can be automatically stopped at a specific position, and if a load (overload) at a certain point is applied while the transplanter, etc. is connected, the safety clutch 6 on the machine 2 side By automatically cutting off the power transmission, it is possible to prevent damage to the connected transplanter or the like due to overload I during planting, in the same way as when the device 1 is connected.

In summary, according to the present invention, the rice transplanter described at the beginning is characterized in that the fixed position stop clutch 5 and the safety clutch 6 are interposed in the transmission system on the side of the main traveling machine 2. .

That is, a fixed position stop clutch 5 is equipped on the side of the main traveling machine 2, and the planting mechanism 4 is configured to automatically stop at a specific position above the ground that will not cause troubles such as damage or deformation during the cutting operation. By doing so, instead of using device 1 for planting,
Even when other attachments are connected to this machine 2, such as a transplanting device that requires or desires to stop at a specific position in the same way as the planting machine 1, it is possible to stop at a fixed position attached to this traveling machine 2. The clutch 5 can be used to automatically stop the attachment at a specific position according to its needs and desires.

Therefore, when trying to make the rice transplanter running machine more general-purpose, it is not necessary to provide a fixed position stop clutch for each attachment, and the attachments can be constructed easily and inexpensively, but it is possible to use connected attachments. It has now been possible to automatically stop the machine at a specified position and use it safely and under good working conditions.

Furthermore, the safety clutch 6 can also be used for general purpose use of the machine as in the case of the fixed position stop clutch described above, which is extremely useful from an economic standpoint.
