[Industrial applications]

 According to the present invention, the seedling transporting section and the planting section are independently configured, and the position of feeding the seedlings from this transporting section and the position of the planting claw of the planting section arranged below this transporting section The present invention relates to a transplanter provided with a positioning stay for accurately matching the above.

[0002]

[Prior art]

 The transplanter mainly used for transplanting long-stem plant seedlings such as “grass grass” to the field arranges tapes on both sides of the base of the seedlings arranged in a thin plate, and spirals this tape portion with a thread. It is used as a band-shaped seedling that is wound into a shape. This belt-shaped seedling is conveyed while holding both sides of the root of the plant with belts in the conveyor and supporting the stem from the lower side. It is cut into pieces and sandwiched by the planting claws that are planted in the planting section, and the root of the plant is inserted into the field and transplanted. For this planting, generally, a single machine is used to plant a plurality of lines of planting at once, and it is known, for example, from Japanese Patent Laid-Open Nos. 3-69034 and 3-180340. In addition, this type of transplanter usually stores a band-shaped seedling in a seedling box in the form of a zigzag, mounts it on the transplanter, conveys it from one end with a conveyor belt, and attaches it to the planting section. It is configured to receive seedlings within the range of nail planting movement.

[0003]

[Problems to be Solved by the Invention]

 A transport unit that continuously transports the band-shaped seedlings from the seedling box to immediately before the planting unit in a predetermined form, and a planting unit that receives the seeds divided into a predetermined number at the lower end of the transport unit and plants them on the rice field. Have independent functions, these devices are manufactured and assembled separately, and when they are mounted on the transplanter, the positions of the two are adjusted. Therefore, it was difficult to adjust the control size of the assembly between the transfer section and the transplanting section, and the planting accuracy of seedlings was likely to be hindered.

Specifically, the front end portion of the planter case is extended laterally of the drive case that receives the power of the traveling machine body, and is fixed to the horizontal frame fixed to the frame of the end portion transfer section. . Therefore, this planter case is cantilevered with respect to the horizontal frame, and it is difficult to keep the position of the planter case accurately with respect to the transport section. When the bolts became loose, it became difficult to maintain the correct distance between the transport section and the planting section.

In addition, in order to prevent damage to the link mechanism and misalignment during transportation, it is necessary to lower the planting part, but the case of the planting part may move due to vibration of the car, etc. There was a problem that the claws and the like would come into contact with the main frame of the transfer section, etc., and it was not possible to accurately transfer seedlings and plant them on the rice field. The present invention has been made to solve the above-mentioned problems, and facilitates the positioning of the seedling feeding position of the transport section and the seedling receiving position of the planting section, and the subsequent misalignment. It is an object of the present invention to provide a transplanter with a stay for preventing the same.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the transplanter of the present invention comprises a transport section for transporting banded seedlings and a transplantation section for transplanting this seedling as independent devices, which are connected by a positioning stay to form a strip shape. It is designed to determine the sending position of seedlings and the receiving position of planting claws.

The positioning stay connects between the frame of the transport unit and the middle part or rear part of the planter case of the planting part, and the front part of the planter case is laterally extended from the drive case and connected. The rear parts of the horizontal cases are supported by the positioning stays, respectively, and the planter case is not supported in a cantilevered manner, and the planter case can be accurately held between the transfer section and the planting section. it can.

[0008]

[Work]

 By connecting the transfer section and the planting section that is provided subsequently with a stay, there is no misalignment between the transfer section and the planting section during transportation or running of the transplanter. Even if a force is applied, this force is transmitted through the positioning stay and is evenly divided, so that the positional deviation is prevented.
