Description

1236339 A7 B7 V. Description of the Invention (1) [Technical Field] The present invention relates to a person-mounted seedling planting machine, and in particular, relates to a clutch installation structure and a lubrication structure in a gearbox. [Background Art] In a passenger-type seedling planting machine of known technology, the clutch mechanism as a gearbox will use the power of the engine to shift speed and transmit the power to the front and rear wheels, which are connected to the output shaft of the engine and the speed change. Between the input shafts of the box, an external clutch forming a belt tension clutch is used to interpose, or the input shaft in the gearbox is used as a double structure, and an internal clutch is set in the middle of the transmission path for the engine Disconnection of power. In addition, the lubrication of the clutch mechanism provided inside the gearbox is performed by lubricating oil which is injected into the gearbox and circulates. However, the former external clutch mechanism is on the same side as the input side of the input shaft, so that the transmission member forming the pulley has a large space necessary for the constant rotation, which leads to the problem that the body is enlarged. In addition, the latter's internal clutch mechanism is difficult to attach and detach because it is fixed inside the gearbox, resulting in problems that the assemblability during manufacture and the maintainability during inspection are poor. In addition, the internal clutch mechanism is fixed inside the gearbox, so it is not easy to attach and detach, resulting in problems of poor assembly performance during manufacturing and poor maintainability during inspection. Furthermore, it is used in up and down intense field operations. At this time, the oil level of the internal clutch changes significantly, and the oil level will rise completely, which will cause burning problems. m.

As shown in FIG. 8, FIG. 13, and FIG. 18, an oil return pipe 1 5 5 of a control valve (not shown) is installed on the right side of the gearbox 6 at the center of the front and rear. The lubricating oil suction pipe 1 5 6 in the gearbox 6 is provided in the lower part of the gearbox 6 0 in the front part of the gearbox 6 and is connected to the obliquely rear of the main gearbox 61 in the gearbox 6 0. Tubular suction filter 1 5 7 side. As a result, in the area from the lower portion of the transmission 6 to the transmission chamber in the middle of the upper portion of the transmission 6, a groove capable of storing lubricating oil is formed. Further, the oil return pipe 15 5 and the suction pipe 1 5 6 hold the chain 80 in order to be arranged to oppose each other. The oil return pipe is returned to the high-temperature oil in the transmission 6 and is driven by the chain 80. It is stirred down to the back and the bottom, and exerts a sufficient cooling effect when the convection gearbox 6 is carried out. Therefore, the high-temperature lubricating oil is not immediately moved to the front suction pipe 156, which can make the oil temperature in the gearbox 6 approximately equal.

Invention Description (31) The transmission mechanism of the clutch mechanism can be changed to correspond, and the cost of parts can be reduced by sharing the clutch mechanism. In addition, the transmission shaft of the input shaft is formed by protruding at least one side of the transmission gear, and a protrusion of the transmission shaft is provided. The clutch mechanism is set to be freely detachable, and the support for supporting the transmission shaft is located inside the gearbox. Therefore, even if the clutch is removed, the input shaft system is often assembled in a fixed position and can be greatly Improve the rationality of the inspection when assembling the clutch mechanism. In addition, the abutment support used by the transmission shaft to support a transmission shaft adjacent to the transmission shaft on the downstream side overlaps at least a part of the outer diameter of the clutch of the clutch mechanism in a side view, and the abutment support system is provided in the gearbox. Internally, the distance between the transmission shaft and the shaft adjacent to the transmission shaft can be reduced, and the required gear diameter can be reduced, enabling miniaturization of the transmission front end. In addition, in the present invention, the power from the engine is input to the gearbox, and the gear is shifted in the gearbox and used to transmit power to the front- and rear-wheel-mounted person-planting seedling plant. The input is protruded from one side of the gearbox. The transmission shaft of the shaft is provided with the clutch mechanism on the protruding portion of the transmission shaft, because the clutch chamber for accommodating the clutch mechanism and the oil passage for communicating with the gearbox are provided on the wall surface of the gearbox with the clutch mechanism Therefore, compared with when the clutch mechanism is provided inside the gearbox, not only can it improve assembly during manufacture and maintainability during inspection, but it can also make the clutch chamber function as a reservoir for lubricating oil.
