Abstract

PURPOSE:To distribute a large amount of stored lubricating oil to every part, by storing lubricating oil in a planting mission case, planting case and planting arm, constructing oil feeding paths connected to the planting mission case, planting case and planting arm. CONSTITUTION:A liquid lubricating oil is stored in a planting mission case 1, a planting arm 3 and every part is sufficiently lubricated by grooves 16a, notched parts 9a, 10a, 20, oiling hole 21,etc. By the rotating action of the planting case 2, the lubricating oil in the planting mission 1 is accelerated to flow through grooves 7a of a driving shaft 7 into the planting case 2 and the lubricating oil in the planting case 2 is promoted to flow through the grooves 13a of a cam axis 13 into the planting arm 3.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lubrication structure for a rice transplanter that plants one row using two sets of planting arms.

In recent years, there has been an increasing demand for faster planting in order to improve the efficiency of the entire rice transplanter operation, and the following structures are available to embody this higher speed. In other words, a planting case is rotatably supported around the horizontal axis of a fixed planting mission case, and a pair of planting arms are pivotally supported at both ends of the planting case, so that one row can be produced by rotating the planting case. Some plants are configured so that two sets of planting arms are used to perform the planting process, which makes it possible to increase the planting speed to nearly twice that of conventional methods.

In the high-speed rice transplanter mentioned above, it is conceivable to apply grease to each part as a lubricant, similar to the conventional machine that plants a single row with the IMi's planting arm, but in this rice transplanter, the planting case is rotatably supported on the planting mission case, both planting arms are rotatably supported on the planting case, and the posture of both planting arms is determined within the planting case. Since the structure is more complex than conventional machines due to the built-in gear mechanism, if you just apply grease, the grease will run out and some parts will become insufficiently lubricated after a relatively short period of time. There is a risk that it will come.

The feature of the present invention lies in the following configuration. In other words, a planting case is provided which is rotated around the horizontal axis of the planting mission case, and a pair of planting arms equipped with a seedling pusher and a planting claw are pivotally supported at both ends of the planting case. As the planting case rotates, both planting arms alternately take out seedlings from the seedling outlet of the seedling stand and plant them in the field, and the planting mission case, the planting case, and the planting arm Liquid lubricating oil is stored inside and an oil passage is formed to communicate the planting transmission case, the planting case, and the planting arm, and its functions and effects are as follows.

As mentioned above, by storing liquid lubricating oil in the planting mission case, planting case, and planting arm instead of paste-like grease, the pivot support of the planting case relative to the fixed planting mission case, and the planting The liquid lubricant will now be distributed to the shaft support of the attachment arm relative to the planting case, the sliding part of the seedling extruder on the planting arm, and the gear mechanism inside the planting case, preventing insufficient lubrication. It will disappear.

Furthermore, since the planting case is driven to rotate around the horizontal axis, centrifugal force acts on the lubricating oil inside the planting case. As a result, even if the lubricant in the planting arm or the planting case is about to run low due to a lubricant leak, the lubricating oil is sucked into the planting case from the planting transmission case through the oil passage, and the lubricating oil is sucked into the planting case from the planting case. Since the lubricant is supplied to the attachment arm, there is no possibility of insufficient lubrication at various parts within the planting case and especially at the sliding parts of the seedling pusher, which are susceptible to wear.

As described above, by effectively utilizing the rotating structure of a high-speed rice transplanter equipped with a 2&Il planting arm in a rotating planting case, a large amount of stored liquid lubricating oil can be distributed to each part. Wear and seizure caused by insufficient lubrication can now be prevented for a long period of time. In particular, in the present invention, since the large-sized planting transmission case with a large volume is also used as a lubricating oil reservoir, there is an advantage that the opening for injecting lubricating oil and removing air associated with this can be set at any location that is easy to handle.
