Description

Light rice transplanter

The utility model belongs to agricultural machinery, and it is the manual rice transplanter that is applicable to the small size rice field.

Before the utility model is made, two kinds of dynamic rice transplanter of rice transplanter that China uses and manual rice transplanters, the former one-time investment is big, is applicable to industrial sprout cultivation dish seedling, and the large tracts of land sowing is not suitable for the current only peasant family of China and uses on than small size.In recent years, several manual rice transplanters of rural area use, structure is relatively heavier, labour intensity is big, it is inconvenient to use, rice transplanting efficient is low, perhaps owing to numerous and diverse, the easy break-down of structure, can not be durable.

The purpose of this utility model provides a kind of light, durable, manual rice transplanter that efficient is high.

The purpose of this utility model realizes with following scheme: it comprises parts such as seedling case, rice transplanter, seedling box mover, frame, hull bottom.Main points are: its rice transplanter is by adjustable shelf and be enclosed within the limiting plate on the adjustable shelf cross bar and be fixed on lubricated the pushing away of sealing on the adjustable shelf that seedling pawl and seedling pin form, and control stick is installed on the adjustable shelf; Pull bar is installed in the middle of the hull bottom, utilizes the spring card on the pull bar to cooperate control seedling needle movement track with the adjustable shelf cross bar, regulates the seedling taking amount with sliding eccentric bushing of joining on the rotating horizontal pole; Seedling box mover adopts helical axis and slide block mechanism, relies on ratchet, ratchet transmission, relies on slide block to drive the seedling case rectilinear motion that is contained on the slip pipe.In addition, in order to use various forms of rice shoot sheets, this machine seedling case is all-in-one-piece, is divided into four parts with dividing plate, and dividing plate can cut the rice shoot sheet; In order to spur light and to gain in strength, the guide plate on the hull bottom is a waveform, and in order to adapt to people's operation of different heights, control stick and pull bar all are adjustable-lengths.

The utility model has the advantages that: owing to adopt the card on simple adjustable shelf cross bar and the pull bar to cooperate, the slideway mechanism and the linkage that have replaced the available man-power rice transplanter to use significantly reduce the part number, so weight saving, reliable operation; Because full machine friction position is few, push away seedling pawl and helical axis, the slide block structure place has all adopted the seal lubrication structure, can operate briskly, part is not easy to wear, needn't often keep in repair and change part, and the precision height; Since simple and reasonable, rice transplanting efficient height, and seedling-damaging ratio is low; Owing to be provided with eccentric bushing, depth adjuster and pull bar, control stick adjusting device, and these adjusting devices are all extremely simple, make the peasant can regulate the length of seedling taking amount, transplanting depth and action bars at an easy rate on demand.
