The present invention relates to a rice transplanter, and more particularly, to a rice seedling shelf mounting device of the rice transplanter to be able to quickly and conveniently install a spare woolen shelf for storing the hair to be supplied to the planting device for planting in the rice paddy.

The rice transplanter is a farming machine used to transplant seedlings, which are grown in the moss, into rice paddies. According to the control method, it is divided into walking and riding. Recently, the rice transplanter is more preferred than walking because of the decline and aging of the agricultural population and the inefficient workability of the walking rice transplanter. Hereinafter, a general configuration of a rice transplanter will be described using a rice transplanter as an example.

Passenger rice transplanters are composed of a vehicle, a planting device which is installed so as to be able to ascend and descends on the rear of the vehicle, and a seedling planting seedling in the paddy field, and a spare mother shelf for storing and storing the seedlings to be supplied to the planting device.

The vehicle includes a main frame that forms the basic frame of the chassis and a body cover that covers the main frame. The body cover is provided with a bonnet at the front and a driver's seat at the rear of the bonnet. In addition, a main step is formed in front of the driver's seat, and sub steps are formed in left and right sides of the bonnet, respectively. The main frame is provided with sub step stays supporting the sub steps on the left and right sides thereof, respectively. Each sub step stay consists of two sets.

The spare bristle shelf consists of a pair of struts and a plurality of trays which are installed in multiple stages on the pair of struts and which have a spare brim placed thereon, which are provided with two bolts and by means of bolts and L-shaped brackets. A pair of struts are respectively mounted on a set of sub-step stays, each positioned on both sides of the bonnet. At this time, the lower end is fixed to the vertical plate of the bracket, and the bracket is fastened with the sub-step stay with the bolt while the horizontal plate is in contact with the upper surface of the sub-step stay.

According to the installation method of the preliminary mother shelf, the preliminary mother shelf is separated from the main frame by loosening the bolts and releasing the fastening of the bracket and the substep stay. In addition, the installation is completed by placing the bracket's horizontal plate against the top of the sub-stay and tightening the bolts.

Specific configuration of a passenger rice transplanter as described above can be found in the specification and drawings of Korean Patent Laid-Open Publication No. 10-2006-0123787.

However, the rice transplanter with the configuration described above requires considerable time and labor to install or detach the spare parent shelf in the vehicle, since the bolts must be tightened or loosened to engage or release the bracket and substep stay. In order to tighten or loosen the wrench, a tool such as a spanner (spanner) is used, so there is a hassle to carry this tool at all times.

Furthermore, when joining the substep stay with the bracket, one person must hold the prop or other part of the spare shelf with one hand, and the bolt must be tightened with the other hand while the bracket is correctly positioned on the upper side of the substep stay. It was not easy to work, so two or more people had to be mobilized.

On the other hand, the installation of the spare mother shelf may be implemented by fastening the horizontal plate of the bracket so as to contact the lower surface of the sub-step stay, as described above. This type of installation prevents unnecessary movement of the bracket located on the underside of the sub-step stay by both side plates of the sub-step stay (the sub-step stay is formed in a substantially 'П' shape) when the bracket and the sub-step stay are fastened. Can be reduced.

The present invention having the configuration as described has the following advantages.

<1> Mounting rods arranged in the up-down direction and rod inserting portions having engaging holes are alternatively provided at the lower end portion of the strut and the sub-step stay tip portion (or mounting stay), respectively, so that the mounting rods are inserted into the engaging holes. When combined with the rod insert, the prop is mounted in the sub-step stay, allowing quick and convenient installation or removal of spare parent shelves.

<2> When the mounting rod is provided in the sub step stay (or mounting stay), the mounting rod is installed to be able to change the height of the upper end such that the mounting rod is installed to be rotated at an angle toward the leading end of the sub step stay. If the post is lowered and the prop is mounted on the sub-step stay, the height of the spare busbar to be lifted for this purpose is lowered (compared to when the mounting rod is up), thereby reducing the force required to install the spare parent rack.

Since it includes a fastening means for fastening the combined mounting rod and the rod insert, it is possible to prevent the unintentional separation of the installed spare parent shelf.

Since the inlet of the coupling hole is formed to be extended, the mounting rod can be easily fitted in the coupling hole.

Since the cutout is formed on the wall of the coupling hole, for example, when the bolt and the nut are used as the fastening means, the inner circumference of the coupling hole is reduced by the fastening means, so that the coupling force of the mounting rod and the rod insertion portion can be improved. In other words, the mounting rod can be prevented from being touched, such as moving in the engaging hole.
