[Industrial applications]

 The present invention is a ridge forming machine which is mounted on the rear side of a rotary tiller to make a flat ridge, characterized in that both shoulders of the ridge are made to form a continuous bank higher than the inside of the ridge. It is about machines.

[0002]

[Prior art]

 When the ridges are erected in the house to make ridges with almost flat ridges, and chrysanthemums and carnations are transplanted and a large amount of water is sprinkled, the ridge shoulders collapse and the water flows down from the ridge shoulders to the groove bottom. Therefore, more water than necessary will be used.Besides, the water flowing out to the bottom of the groove will make it difficult to walk due to the muddy bottom of the groove.Therefore, in order to prevent the water sprinkled in the groove from flowing down, It took a lot of time and labor to make a bank on the shoulder.

[Function of the device]

 In the ridge molding machine of the present invention, the ridge upper surface leveling portion is fixed at a required position by straddling the ridge side surface forming portions which are arranged facing each other, and the ridge upper surface leveling plate of the ridge upper surface leveling portion is fixed. Are arranged horizontally to the right and slightly upward, and the ridge upper surface leveling plate has the steps of the steps formed by its both ends inside the ridge side surface forming section, and the steps have steps. Since it is formed at a position higher than the ridge upper surface leveling plate connected to the inside of the ridge, a step is formed when the ridge is formed by the ridge forming machine while cultivating with the rotary tiller. The soil rises high in the space, and the soil is pressed into the shape of the space formed by the stepped portion, and a trowel can be made to make continuous banks on the ridge shoulders on both sides of the ridge.

[Effect of device]

 As described above, in the ridge forming machine according to the present invention, the ridge upper surface equalizing portion is placed and fixed on the upper end of the ridge side surface forming plate, and the inside of the ridge side surface forming portion is higher in the ridge upper surface equalizing portion. Since there is a stepped portion so that the soil can be heaped up, the ridge molding machine progresses to form the ridge and at the same time make a firm bank on the ridge shoulder. Since the raised soil is pressed and solidified at the step, even if a large amount of water is sprinkled, the bank on the ridge shoulder is not easily broken down, and it is effective in saving water and preventing the mud from the groove.
