Abstract
an airflow jet type rice seedling planting system drawn by a tractor has a row of downward vertical airflow nozzles which can regularly eject airflow pulses to vertically jet the rice seedlings in seedling cultivating tray placed on seedling tray moving mechanism into paddy field surface soil one by one. The pulsating airflow, the seedling tray moving mode and the tractor progressive speed are linked so as to attain the seedling field with plant spacing and row spacing incompliance with the requirement.
Description
The invention provides a kind of airflow spray type rice seedlings transplanting system, the alternative artificial at present and mechanical rice seedling throwing operation of this system.The rice transplanting operation is that one-tenth is thrown to rice shoot in the air, utilize gravity and act on rice shoot and the different air drag of rice shoot root clod, makes the rice shoot root vertically insert paddy field earth and finishes the rice transplanting operation.The transplanting depth of rice transplanting operation, especially the rice shoot distribution consistency degree all very easily is subjected to nature (as natural wind) and human factor (as rice transplanting height, angle, the confession seedling uniformity) influence, the invention provides a kind of airflow spray type rice seedlings transplanting system for overcoming these unfavorable factors, this system (constitute sketch and see accompanying drawing) mainly is made up of following several parts.
1, air compression induction system (accompanying drawing does not draw).
2, row air-flow nozzle (1) vertically downward, air-flow nozzle (1) has valve and is connected with blowpipe (2).
3, seedling dish (7) is a plate like structure, the many holes (13) that distributing on the plate face, and hole (13) is arranged in length and breadth by certain interval, each hole (13) [is last with rice shoot (9) direction of growth] wide at the top and narrow at the bottom, hole (13) bottom surface is penetrating.
4, seedling dish travel mechanism (accompanying drawing does not draw).
5, rice shoot guide pipe (6) is the pipe of one section vertical ground, and its upper end is to positive airflow nozzle (1).
6, the interlock controlling organization (accompanying drawing does not draw) of air-flow nozzle (1), seedling dish travel mechanism and hauling machine.
Airflow spray type rice seedlings transplanting system operation principle accompanying drawings is as follows:
When hauling machine (as tractor) is born or is drawn this rice seedlings transplanting system walk operation on the paddy field, close after between valve open Shun of air-flow nozzle (1), air-flow nozzle (1) sprays one air pulse, impact cave rice shoot (9) the root clod (8) in the compressing below seedling dish (7), make clod (8) obtain acceleration, hightail seedling dish (7) hole (13), clod (8) is inconjunction with rice shoot (9) and passes hole (13) bottom surface together, again by rice shoot guide pipe (6) then rice shoot (9) root clod (8) vertically penetrate and insert paddy field table soil (3), promptly finish the rice transplanting operation of this subpulse.Because the perpendicular air-flow nozzle (1) of a row and tractor direction of advance [shown in accompanying drawing (10) arrow] is worked simultaneously, every ejection pulsatile once air-flow can be inserted row's rice shoot (9), and the interval of adjacent two air-flow nozzles (1) is exactly the spacing in the rows (5) after the rice transplanting.The effect of rice shoot guide pipe (6) is to guarantee that rice shoot (9) is vertically down slotting and make full use of the air pulse energy.Along with tractor advances by [shown in the direction of advance accompanying drawing (10)], whenever move a setpoint distance [being rice shoot (9) line-spacing (4)] by link gear, open air-flow nozzle (1) once more, air pulse is inserted next row's rice shoot (9) again.Between twice air pulse, seedling dish travel mechanism seedling dish (7) can be turned left or turned right or backward [in the accompanying drawing shown in (14) and (11) arrow] move an acupuncture point, and air-flow nozzle (1) and rice shoot guide pipe (6) do not move relative to tractor, so just guarantee all to have shortly before each air pulse sprays cave rice shoot to be inserted (9) to move to air-flow nozzle (1) below.Seedling dish travel mechanism makes seedling dish (7) pulsation line by line scan by the cave, promptly form " bow " font (12) move mode, this move mode can have been inserted none omission of each cave rice shoot (9) of seedling dish (7), discharges empty seedling dish (7) while seedling dish to be inserted (7) is added in the rice transplanting on one side of this move mode.
Airflow spray type rice seedlings transplanting system of the present invention is because there is adjustable stable power (air pulse), configure air-flow nozzle (1) interval and air pulse interval accurately, can guarantee that rice shoot (9) insertion depth is adjustable, spacing in the rows (5) line-spacing (4) is accurate, and it is less influenced by nature and human factor.
Claims (5)
1, a kind of airflow spray type rice seedlings transplanting system, this system is mainly compressed air-flow nozzle (1), seedling dish travel mechanism, seedling dish (7), the rice shoot guide pipe (6) of induction system, band valve by air, and the controlling organization composition of air-flow nozzle (1), seedling dish travel mechanism and hauling machine interlock, it is characterized in that:
With the air-flow nozzle (1) of valve, what air-flow nozzle (1) sprayed is air pulse vertically downward for a, a row.
Hole (13) on b, seedling dish (7) plane is arranged at regular intervals in length and breadth, and each hole (13) is wide at the top and narrow at the bottom, and hole (13) bottom surface is penetrating.
C, rice shoot guide pipe (6) are one section and face air-flow nozzle (1) pipe vertically downward.
D, seedling dish (7) are that pulsation is pursued the cave, lined by line scan by seedling dish travel mechanism move mode, promptly form " bow " font (12).
2, it is characterized in that according to the described system of claim 1: with the air-flow nozzle (1) of valve, what air-flow nozzle (1) sprayed is air pulse to a row vertically downward.
3, seedling dish according to claim 1 (7) is characterized in that: hole (13) bottom surface is penetrating.
4, it is characterized in that according to the described system of claim 1: rice shoot guide pipe (6) is one section pipe vertically downward that faces air-flow nozzle (1).
5, it is characterized in that according to the described system of claim 1: seedling dish (7) is that pulsation is pursued the cave, lined by line scan by seedling dish travel mechanism move mode, promptly forms " bow " font (12).
