Specific embodiment
Below in conjunction with the accompanying drawings, the present invention program is described in further details.
As shown in figure 1, be water suction filter apparatus configuration figure, by storage tank 1, filter 2, water pump 3 and water intaking branch road successively
Connection composition；Water intaking branch road all includes switch valve 4, pipeline 5, water inlet pipe 6 and water leg 7.Water intaking branch road can be multiple, according to reality
Border operation needs, and with the road of 1-3 water intaking in parallel, and can manually adjust the opening and closing of switch valve 4, and then adjust water intaking branch road on demand
Quantity.
As shown in Fig. 2 being the structural representation of water leg, water leg 7 includes screen pack 8, top board 9, backboard 10, base plate
11st, side plate 12 and tank locator 13, wherein the top board 9, base plate 11, side plate 12 are rectangle face, base plate 11 and backboard
10 are connected through the hinge, and base plate 11 is connected with side plate 12 by telescopic plastics fold cloth, when dead furrow bottom of trench not usually, base plate
11 can rotate upwardly and downwardly relative to backboard 10, to keep the stability of water suction work.Side plate 12 is fixedly connected with backboard 10, top board
9 are bolted to connection with side plate 12 and backboard 10, and screen pack 8 is bolted to connection with side plate 12；As shown in figure 3,
It is the structural representation of water leg screen pack 8, the screen pack 8 is inverted trapezoidal side, and the backboard 10 for being all inverted trapezoidal side
Corresponding, the top of the screen pack 8 is filter screen, and bottom is connected with water tightness closure, in order to stop impurities at bottom
Into the screen pack 8 on water leg 7 can carry out coarse filtration to the water for entering water leg 7；As shown in figure 4, being the grooved top plate 9 that catchments
Structural representation, the mounting hole with water inlet pipe 6 on the top board 9 of water leg 7, the installation of the pipeline 5 of water inlet pipe 6 from top board 9
Hole penetrates, and is fixedly connected by nut with top board 9.Water leg 7 also includes tank locator 13, and tank locator 13 includes bullet
Property support 14, damper 15, strain transducer A16 and strain transducer B17, elastic support 14 are fixed on the both sides side of water leg 7
Near the medium position of backboard 10, damper 15 is connected plate 12 with elastic support 14, strain transducer A16 and strain transducer
B17 is fixed on the junction of elastic support 14 and side plate 12, senses the deformation of elastic support and exports strain signal.
The width of the water leg 7 is 10~15cm, less than the half of paddy field dead furrow width；The height of water leg be 10~
15cm, less than the depth of paddy field dead furrow；The rear end level of base plate 11 of water leg 7, front end is inclined upwardly 5 °~10 °, to reduce suction
Silt mixed volume during water.The rear end level of base plate 11 of water leg 7, can store the water of more relative clean, to ensure to supply
Water is sufficient, though front end be inclined upwardly can make unit touched during advance dead furrow bottom will not also suck it is substantial amounts of
Soil and impurity, keep water quality cleaner.The base plate 11 of water leg 7 can be opened, and be convenient to clean impurity and maintained equipment.
2/3 of the width of the elastic support 14 less than paddy field dead furrow width.
Setting angle between the damper 15 and elastic support 14 is adjustable, can be according to paddy field dead furrow width adjustment two
Subtended angle between damper 15, makes the distance between two dampers 15 be approximately equal to the width of dead furrow, and two dampers 15
Touched with the both sides furrow bank of dead furrow respectively end.During unit advance, if being offset slightly from desired trajectory, cause damper
15 touching paddy field dead furrow both sides furrow banks, elastic support 14 can make water leg 7 be maintained at dead furrow middle position by elastic deformation,
Ensure that unit steadily advances and absorbs water.Strain transducer A16 and strain transducer B17 constitutes two arms of inductance bridge.Work as machine
When group deviation desired trajectory is larger, damper 15 is extruded to side dead furrow furrow bank, and the deflection of two-side elastic support is different, strain
Sensors A 16 is different with the strain that strain transducer B17 is sensed, electric bridge is unbalance.When bridge output signal is more than given threshold
When, control system receives bridge output signal and alarms, and points out driver adjustment unit direction of advance, readjusts water fetching device
Position, is returned in groove.
Described damper 15 is two rubber bars.
In rice terrace the dead furrow that 25cm-40cm is deep, 25cm-40cm is wide is excavated at interval of a certain distance.
It should be understood that above-mentioned example of applying is only illustrative of the invention and is not intended to limit the scope of the invention, the present invention is being read
Afterwards, modification of the those skilled in the art to the various equivalent form of values of the invention falls within the application appended claims and is limited
Scope.
