Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a riding-type rice transplanter comprising a seedling planting device attached to the rear of a traveling machine on which an operator rides.

[Conventional technology]

In the conventional riding rice transplanter in which the seedling transplanting device is attached to the rear of the traveling machine on which the operator rides, as disclosed in Japanese Utility Model Publication No. 52-55825, for example, the traveling machine is An engine stand protrudes forward from the front of the engine, and an engine is mounted on the top of the engine stand, while a handle for controlling the traveling aircraft is generally provided at the rear of the engine, and the fuel for the engine is The tank is
It was attached to the engine itself.

[Problem that the invention attempts to solve]

However, in this way, the engine's fuel tank,
If it is installed on the engine itself, the heat of the engine will be directly transmitted to the fuel tank and the fuel will become hot, so there is not only a great risk of fire, but also the vibrations of the engine will be transmitted to the fuel tank, causing damage to the welded parts in the fuel tank. may be damaged and cause fuel leakage,
Alternatively, there was a problem in that fuel leakage occurred due to the fluctuation of the fuel.

The present invention aims to solve this problem without impairing the maintainability of the engine.

That is, the present invention solves the above-mentioned problem by attaching the fuel tank for the engine to a stand installed on the engine stand so as to straddle the engine mounted on the stand. It reinforces the control handle of the aircraft and supports the bonnet that covers the engine.

[Means to solve the problem]

For this reason, the present invention has an engine stand on which an engine is mounted protrudes forward from the front of a traveling body equipped with a seedling planting device at the rear, and a steering column having a control handle at the upper end is erected at the rear of the engine. , and a riding rice transplanter in which a bonnet covering the engine and its fuel tank is provided on the engine stand so as to be openable and closable; The formed bracket is disposed, and a strut member extending downward from the front ends of both the left and right horizontal bars of the bracket is fixed to the engine stand at a portion forward of the engine, while a portion between the rear ends of both horizontal bars is fixed to the engine stand. The fuel tank is placed on the upper surface of both the left and right horizontal rods in the bracket, and the bonnet is connected to the bracket. It is designed to be removably locked.

[Effect]

In this way, by attaching the fuel tank of the engine to the engine stand using a bracket, it is possible to avoid direct transmission of heat and vibration from the engine to the fuel tank. By connecting the end to the steering column of the control handle,
This bracket and steering column as a whole form a gate-shaped structure when viewed from the side of the traveling aircraft, and the rigidity of each of them is mutually improved.
Furthermore, since the bonnet that covers the entire engine and fuel tank is engaged with the portal-shaped bracket as described above, the support of the bonnet is also strengthened.

Moreover, the bracket that supports the fuel tank is formed in a U-shape in the longitudinal direction of the traveling aircraft when viewed from above, and the strut members extending downward from the front ends of both left and right horizontal rods are positioned in front of the engine. By connecting a horizontal rod that is fixed to the engine stand at a portion and connects the rear ends of both horizontal rods at a portion rearward of the engine to the steering column of the control handle, the bracket can support the engine. Since the bracket is straddled, it is possible to avoid the bracket from getting in the way during maintenance such as inspection and repair of the engine, and engine replacement.

[Effect of idea]

Therefore, according to the present invention, under conditions that do not impair the maintainability of the engine, malfunctions due to the transfer of heat and vibration from the engine to the fuel tank, such as fire occurrence, damage to the fuel tank, and leakage from the fuel tank, can be prevented. It is possible to reliably reduce the occurrence of fuel leakage, the rigidity of the support structure of the fuel tank and the control handle can be mutually improved, and the weight can be reduced, and the support of the bonnet is strong, and the bonnet is This has the effect of preventing an increase in noise due to vibration.
