Model utility content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is the light high pressure water pump providing plant protection unmanned plane sprinkling system, can export higher outlet pressure on the basis that volume is little.
The purpose of this utility model realizes by the following technical solutions:
The light high pressure water pump of plant protection unmanned plane sprinkling system, casing, sleeve, motor, piston shaft, eccentric wheel, bearing and pumping cylinder, pumping cylinder butts up against casing side, piston shaft activity cross-under is in casing and stretch into pumping cylinder, the axle body of this piston shaft is provided with flat position, this flat position is fixed in the outer ring of bearing, and the inner ring of bearing is fixed in eccentric periphery, and this eccentric center fixed cover is loaded on the lower end output shaft of motor; Electric machine built-in is in sleeve, and sleeve is fixed on casing top, and bottom half is fixed with damping screw removably.
Preferably, the top of described motor is fixed with fixed tray, and this fixed tray is covered with fan housing, and fan housing is built-in with radiation fan, and this radiation fan fixed cover is loaded on the upper end output shaft of motor.
Preferably, the outboard end capping of described pumping cylinder has pump cover, and the casing side capping relative with piston shaft has capping.
Preferably, the side of described casing has filler opening, and this filler opening is bolted with nut.
Preferably, described motor is brushless electric machine.
Compared to existing technology, the beneficial effects of the utility model are:
The utility model is rotated by driven by motor eccentric wheel, and then with the eccentric bearing that is rotatably assorted to make piston shaft reciprocating in casing, High voltage output is produced to extrude after the liquid such as spraying agent, seed, pulvis enter pumping cylinder, because its eccentric rotation conversion ratio is high, therefore its elevated pressures achieved on small volume basis exports, to reduce the load of unmanned plane, extend cruising time of flying, and be easy to carry.
Accompanying drawing explanation
Fig. 1 is the structural representation of the light high pressure water pump of the utility model plant protection unmanned plane sprinkling system;
Fig. 2 is the structural representation after Fig. 1 removes sleeve and casing;
Fig. 3 is the eccentric structural representation of the utility model.
In figure: 10, casing; 101, capping; 102, filler opening; 103, nut; 104, damping screw; 20, sleeve; 30, motor; 40, piston shaft; 401, flat position; 50, eccentric wheel; 60, bearing; 70, pumping cylinder; 701, pump cover; 80, fixed tray; 801, fan housing; 802, radiation fan.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
The light high pressure water pump of plant protection unmanned plane sprinkling system as shown in Figures 1 to 3, casing 10, sleeve 20, motor 30, piston shaft 40, eccentric wheel 50, bearing 60 and pumping cylinder 70, pumping cylinder 70 butts up against casing 10 side, piston shaft 40 activity cross-under is in casing 10 and stretch into pumping cylinder 70, the axle body of this piston shaft 40 is provided with flat position 401, this flat position 401 is fixed in the outer ring of bearing 60, the inner ring of bearing 60 is fixed in the periphery of eccentric wheel 50, and the center fixed cover of this eccentric wheel 50 is loaded on the lower end output shaft of motor 30; Motor 30 is built in sleeve 20, and sleeve 20 is fixed on casing 10 top, is fixed with damping screw 104 removably bottom casing 10.
Movable eccentric wheel 50 is with to rotate by motor 30, and then with the bearing 60 that is rotatably assorted of eccentric wheel 50 to make piston shaft 40 reciprocating in casing 10, High voltage output is produced to extrude after the liquid such as spraying agent, seed, pulvis enter pumping cylinder 70, because the rotation conversion ratio of its eccentric wheel 50 is high, therefore its elevated pressures achieved on small volume basis exports, to reduce the load of unmanned plane, extend cruising time of flying, and be easy to carry.Particularly, band movable eccentric wheel 50 rotates by the rotating power that motor 30 lower end output shaft exports, the rotation of eccentric wheel 50 will be with dynamic bearing 60 inner ring to rotate, because bearing 60 outer ring is limited in flat position 401, and piston shaft 40 is limited in casing 10 and makes sliding action, therefore the rotational action of eccentric wheel 50 will be converted into the action that reciprocatingly slides of piston shaft 40, liquid in pumping cylinder 70 is extruded to make piston shaft 40, circulation produces extruding force and forms higher outlet pressure, this pressure reaches as high as 8Mpa, and normal operating pressure is 4Mpa ~ 5Mpa.Damping screw 104 adopts rubber shock-absorbing screw, and this damping screw 104 is for installing this water pump.
Motor 30 preferably uses brushless electric machine, then its rotating speed of available signal telecontrol, controls flow and pressure size to reach.
Work for keeping more permanent motor 30, prevent motor 30 from crossing cause thermal damage, the top of motor 30 is fixed with fixed tray 80, this fixed tray 80 is covered with fan housing 801, fan housing 801 is built-in with radiation fan 802, this radiation fan 802 fixed cover is loaded on the upper end output shaft of motor 30, and fan housing 802 can stop foreign matter interference radiation fan 802 and motor 30 simultaneously.
For strengthening the sealability of casing 10, the outboard end capping of described pumping cylinder 70 has pump cover 701, and pump cover 701 one end seals, and the other end has intake-outlet; The casing 10 side capping relative with piston shaft 40 has capping 101, and this enters in casing 10 for preventing foreign matter.For vibrations when alleviating this pump working are on the impact of unmanned plane, adopt rubber shock-absorbing screw 104 to be flexible coupling during installation, reduce the impact of vibrations on unmanned plane.In addition, also can set up the air locking of O RunddichtringO, oil sealing at the connection part of each element, to keep the high sealing state of casing 10, be beneficial to export high-pressure.
For lubricating each element in casing 10, the side of described casing 10 has filler opening 102, and this filler opening 102 is bolted with nut 103.
To one skilled in the art, according to technological scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
