Summary of the invention:

Task of the present utility model will provide a kind of labour intensity on the low side exactly, the point type chemical fertilizer fertilising instrument that back of the body case is arranged that efficiency is higher.

The purpose of this utility model be achieved in that a kind of point type chemical fertilizer fertilizer applicator that back of the body case arranged by intubate (1), pedal (2), blanking chamber (3), pull bar (4), keep off native bar (5), feed bar (8), back of the body case (9), proportional valve (11), back of the body case band (12), flexible pipe (13) is formed.It is characterized in that intubate (1) is connected with flexible pipe (13) by blanking chamber (3), flexible pipe (13) is connected with back of the body case (9); Intubate (1) with can be connected with its movable vertically retaining soil bar (5) again with its axial locking; Proportional valve (11) is connected with back of the body case (9), can regulate what control amount core (10) of each fertilizing amount and be connected with proportional valve (11).

Optimum implementation of the utility model is: intubate (1) upper end is connected with blanking chamber (3), and blanking chamber (3) upper end is connected with pull bar (4); Proportional valve (11) is a up-and-down motion type, it and up and down connection of lower end of carrying on the back case (9), and feed bar (8) is fixedlyed connected with proportional valve (11), the up and down connection of top of feed bar (8) and back of the body case (9).

The utility model has following advantage compared with the prior art:

1, because the utility model has adopted back of the body case (9), thereby saved the time of between the fertilising diverse location, moving portable vessel, and when in the soil, applying fertilizer, just go up drop-down one-time feeding bar (8), in vessel, adorn a chemical fertilizer than fertilizer applicator and also save time.Thereby what the utility model can be bigger than existing fertilizer applicator raises labour efficiency.

2, owing to the utility model intubate (1) can be connected with its movable vertically retaining soil bar (5) again with its axial locking; thereby earth can not enter intubate (1) when intubate (1) is inserted the soil; when the native bar of retaining (5) made progress movable disengaging intubate (1), granular chemical fertilizer can flow into the inner chamber of intubate (1) smoothly by blanking chamber (3).When intubate (1) was extracted from the soil, granular chemical fertilizer can and keep off the suitable depths that gently depressing of native bar (5) flows into the soil in deadweight, needn't push in the soil granular chemical fertilizer again, thereby reduce labor intensity, and has saved working time.
