DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a roof structure for improving the comfort of a rider of a riding rice transplanter.

[0002]

2. Description of the Related Art Conventionally, the use of a riding type rice planter capable of traveling in a field such as a deep rice field or a wet rice field has made it relatively easy to plant seedlings over a wide rice field. In such a conventional rice planting machine, generally, a spare seedling tray for loading spare seedlings on the left and right sides of the bonnet is provided so that seedlings can be loaded as much as possible, and the driver sets the seedlings in the planting section. When the seedlings are planted and lost, the operator stands on one of the left and right sides of the driver's seat and performs the work of replenishing the seedlings from the spare seedling tray to the planting section.

[0003]

Generally, during the rice planting season, the temperature is relatively low, but the sunlight is very strong. If the weather is good, the driver who is exposed to direct sunlight will be significantly fatigued. On the other hand, when it is raining, there is a strong demand to avoid rain and wind while driving.

On the other hand, it is conceivable to provide a roof for protecting the driver from sunlight and rain and wind. However, in this case, although the livability in the driver's seat is improved, the roof may hinder the driver's work in the operation of replenishing the spare seedlings performed in the limited space on the left and right of the driver's seat as described above. There is.

[0005] The present invention has been made in view of such a point, and an object thereof is to provide a riding type rice transplanter,
An object of the present invention is to provide a roof that sufficiently covers the top of the driver's seat to improve livability and that does not hinder work on the vehicle body such as replenishment of spare seedlings.

[0006]

In order to achieve the above-mentioned object, according to the solution of the present invention, the riding type rice planting machine does not hinder the replenishing operation of the open state and the spare seedling for protecting the driver during operation. An open / close roof member that can be switched to one of the closed states is provided.

Specifically, according to the first aspect of the present invention, pillars are erected on a vehicle body of a riding type rice transplanter so as to extend vertically in front and rear sides of a driver's seat, respectively.
An opening / closing roof member is provided at least above the driver's seat between the front and rear pillars, and the opening / closing roof member has a configuration in which a dimension in a vehicle width direction in a closed state is shorter than that in an open state.

[0008] According to this configuration, by opening the openable roof member provided above the driver's seat, the driver sitting on the driver's seat and driving the riding rice transplanter can be operated by the driver.
It is protected from midday direct sunlight and rain and wind, which improves comfort and reduces fatigue. In addition, when work such as replenishment of spare seedlings is performed on the vehicle body, the open / close roof member is switched to a closed state in which the size in the vehicle width direction is shorter than the open state, so that the open / close roof member is used for a driver's work. Disturbance is suppressed. In other words, both improvement of the livability and securing of good workability are achieved.

According to a second aspect of the present invention, in the first aspect of the present invention, a center frame is provided extending in the front-rear direction of the vehicle body and connecting the upper ends of the front and rear pillars. An open state consisting of a pair of left and right openable roof members, rotatably supported by the center frame about a support shaft extending in the front-rear direction of the vehicle body, and an open state extending along a substantially horizontal plane, and a state in which a front end portion is positioned above. With this configuration, it can be opened and closed between closed states along a substantially vertical plane.

In this configuration, a pair of left and right opening and closing roof members are rotatably connected to and supported by the center frame about a support shaft in the longitudinal direction of the vehicle body. In a closed state, the vehicle is closed along a substantially vertical plane, and becomes extremely short in the vehicle width direction. That is, the openable and closable roof member can be easily opened and closed with a simple configuration, and the driver can be sufficiently protected in the open state, but does not hinder the work in the closed state.

According to the third aspect of the present invention, only one pillar on the rear side of the driver's seat in the second aspect is provided substantially at the center in the vehicle width direction. Thus, when the driver performs work such as replenishment of spare seedlings on the vehicle body, it is possible to reduce that the rear pillar hinders the work.

According to the fourth aspect of the present invention, there is provided the second or third aspect.
The driving seat according to the invention described above is urged by an urging means to an empty position higher than the boarding position, and is configured to move to the empty position when the driver separates, and the driver seat is moved to the boarding position. The driving seat and the pair of opening and closing roof members are connected such that the opening and closing roof member is opened when the driver seat is positioned, and the opening and closing roof member is closed when the driver seat is positioned at the empty position. A connecting member is provided.

[0013] With this, when the driver is sitting on the driver's seat and driving the rice transplanter, the driver's seat is positioned at the boarding position and the opening / closing roof member is opened, while the driver is in the open position. When the driver's seat leaves the driver's seat, the driver's seat is urged upward by the urging means and moves to the empty position, whereby the opening / closing roof member rotates and is closed. That is, since the opening / closing roof member is opened / closed in accordance with the operation of the driver, convenience is improved.

According to a fifth aspect of the present invention, in the fourth aspect of the present invention, a lock mechanism is provided for holding the driver's seat at the riding position against the urging force of the urging means.

[0015] Thus, even when the driver is not seated, the openable roof member can be maintained in the open state extending substantially horizontally by holding the driver's seat at the boarding position. That is, since the opening / closing roof member can be prevented from protruding above the center frame, the rice transplanter can be stored in a garage having a low ceiling.

According to a sixth aspect of the present invention, a minute movement is not transmitted to the connecting member according to the fourth aspect of the present invention so that the minute movement of the driver seat at the boarding position to the empty position is not transmitted to the opening / closing roof member side. Means were provided. Thus, for example, even if the driver's seat at the boarding position vibrates up and down during traveling of the rice transplanter, the vibration is absorbed by the small movement non-transmission means and is not transmitted to the open / close roof member side. The members do not flutter.

[0017] The small movement non-transmission means includes:
For example, when a wire or a chain is used as the connecting member, the wire or the chain may be configured to allow a predetermined amount of play in a state where the driver's seat is positioned at the boarding position, and a rod is used as the connecting member. In this case, the rod may be configured to be able to expand and contract by a predetermined amount.

According to the seventh aspect of the present invention, the connecting member according to any one of the fourth, fifth and sixth aspects is a wire for connecting the driver's seat and the pair of opening and closing roof members. Thus, the wire as the connecting member can be easily attached, so that the degree of freedom in the layout of the driver's seat and the opening / closing roof member is improved.

According to the invention described in claim 8, the pillar on the rear side of the driver's seat in any one of claims 4 to 7 includes:
A hole penetrating from the upper end to the lower end is formed,
The connecting member was inserted through the hole. Thereby, the connecting member is compactly stored in the pillar, and the appearance is improved.

According to a ninth aspect of the present invention, the pair of opening and closing roof members of the connecting member according to any one of the fourth to eighth aspects has a pair of lower ends rotatably connected to the driver's seat side. A link member is provided, and one of the pair of link members has an upper end rotatably connected to one of the pair of openable / closable roof members, and the other link member has an upper end connected to the other. It is configured to be rotatably connected to the opening / closing roof member. Thus, the pair of opening and closing roof members are respectively opened and closed in synchronization with each other by receiving the force from the connecting member.

According to the tenth aspect, the fourth to ninth aspects are provided.
The pair of left and right opening and closing roof members in the invention according to any one of the above, is rotatably connected to and supported by the center frame by rotating hinges respectively rotating around the support shaft,
At the ends of the pair of openable roof members on the center frame side, left and right brackets that are rotatably connected to upper ends of connection members are provided alternately in front and rear, respectively, and the pair of openable roof members is provided. When in the open state, the connection position of the right bracket with the connection member is located on the left side of the left and right center positions of the center frame, while the connection position of the left bracket with the connection member is The configuration is such that the center frame is positioned on the right side of the left and right center positions.

According to this configuration, when the openable roof member is in the open state, the point of application (connection position) of the force from the connecting member to each of the left and right brackets is a support serving as the rotation center of each of the brackets. Since it is arranged so as to be far from the shaft, a sufficiently large moment can be applied to each bracket around the support shaft by the force from the connecting member. Therefore, the force required when rotating the opening / closing roof member can be reduced.
