Abstract
The utility model discloses a vertical motor-driven pump for a motor-driven sprayer, relating to a vertical pump. The utility model is provided with a connecting shell with elastic struts, and a motor and a water pump are connected together by the connecting shell. The motor is installed in the supporting hole of the connecting shell vertically downwards, and the water pump is inserted between the elastic struts. The supporting legs of a water pump cover is connected with the bottom legs of the elastic struts. The rotating shaft of the motor is inserted into a bushing which is install in the center of the outer shell of the water pump, and the pore diameter of a through-flow inlet on the lower part of the bushing is larger than the diameter of the bottom of an impeller. The utility model solves the problem that the existing sprayer adopts a horizontal type water pump which makes the motor and the water pump have easy damage, poor spraying performance and inconvenient operation. The utility model is suitable for various electric sprayers.
Description
The utility model relates to a kind of vertical pump, particularly sprays the motor-drive pump of the electrodynamic type sprayer of agricultural chemicals thing etc.
When existing electrodynamic type sprayer is worked, its motor and water pump are horizontal positioned, easily infiltrate agricultural chemicals in the motor, also easily solidify agricultural chemicals on the water pump, this not only causes the heavy corrosion wearing and tearing of motor and water pump, not quick detachable washing maintenance, liquid such as agricultural chemicals infiltrates by the side and produces over load during also because of operation, and it is very inconvenient to operate.
The purpose of this utility model is to address the above problem, provide be difficult in a kind of motor infiltrating agricultural chemicals, dismounting and easy to operate, load is little, the erect type motor-drive pump that jet performance is good.
Above-mentioned purpose is realized by following scheme:
With electronic device above water pump, utilize the coupling housing of a band elastic support that motor and water pump are joined together, motor vertically downward, the assembly department of its shell inserts and is fixedly linked in the seat hole on coupling housing top, its rotating shaft is inserted in the axle bush of installing in the pump shell central part stepped bore, and water pump places between elastic support, and its impeller is installed in the motor rotary shaft axle head, be equipped with inflow entrance and exhaust port on the pump shell, the leg of water pump cover is fixed on the footing of elastic support.
The pump shell central part has the stepped shaft endoporus that communicates with inflow entrance, and the endoporus epimere is provided with axle bush, is slightly larger than the impeller blade base diameter in the water inlet aperture of axle bush bottom.
Pump shell inflow entrance outer surface and pump shell junction point are provided with positioning boss, and the bi-side of this boss are close between adjacent two elastic supports.
Between the opening portion of water pump cover boss epimere and pump shell, be equipped with a seal ring.
Adopt said structure, the utlity model has following advantage: 1, because motor is fixed on the water pump top, things such as agricultural chemicals have not only been prevented to infiltrate in the motor, and prevented reduction machine proper property, and 2, medicine central part input above pump impeller, load is little during high speed rotating, thermal diffusivity is good, 3, be easy to dismounting maintenance, 4, motor and water pump life-span prolong, 5, the rubber-like support can absorb and reduce to shake.
Accompanying drawing 1 is an outline drawing of the present utility model;
Accompanying drawing 2 is pump shell and impeller worm's eye view;
Accompanying drawing 3 is exploded perspective views of the present utility model;
Accompanying drawing 4 is the utility model erection drawings;
Accompanying drawing 5 is that the utility model uses diagram.
Further specify embodiment in conjunction with the accompanying drawings:
Motor 2 vertically downward, its shell rear portion have vent hole 22,22 ', the assembly department of its shell is inserted in the seat hole 25 of coupling housing 4 top cylinder shape bearings 36, pass fixed hole 8,8 ' be screwed into screw 27,27 ' fix with coupling housing 4 with sunk screw 10.Water pump 3 inserts elastic support 5,5 ', 5 " between, and utilize its inflow entrance 12 outer surfaces and the set rectangular boss 11 of pump shell 3 ' junction point that its spacing system is changeed.Pump shell 3 ' have inflow entrance 12 and exhaust port 13, exhaust port 13 passes to water pump tap hole 38.The axis hole 9 of motor casing rotating shaft 2 ' pass coupling housing 4 inserts in the axle bush 15 of water pumps 3 ' central part, this axle bush 15 is installed in the axle bush hole 14 in shoulder hole 39,39 ' table top stage casing, shoulder hole bottom blasthole 37 communicates with inflow entrance 12, impeller 16 is with 17 location, hole, be fixed on motor shaft 2 ' axle head, the slightly larger in diameter of blasthole 37 is in impeller 16 base diameters, so that liquid such as agricultural chemicals can flow into impeller 16 central parts.Water pump cover 19 has leg 24,24 ', 24 "; on it porose 23; 23 '; 23 " with the elastic supports 5 of coupling housing 4,5 ', 5 " footing 6; 6 '; 6 " bolt hole 7,7 ', 7 " correspondence; the central part of water pump cover 19 is provided with ring trapezoid boss 28; 28 '; seal ring 18 is packed into last layer boss 28; and with its top insert pump shell 3 ' opening portion; and then with the bolt 20 and the hexagonal counterbore 26 of packing into, 26 ' in nut 21 with the leg 24 of water pump cover 19,24 ', 24 " with the footing 6 of elastic support; 6 '; 6 " be connected and fixed, dress up electrodynamic type sprayer erect type motor-drive pump at last.
The connecting relation of each parts when Fig. 5 has represented to use, complete machine is an electrodynamic type antomobile sprayer 30, motor-drive pump 1 is joined together through coupling housing 4 by motor 2 and water pump 3 to be formed, exhaust port 13 links to each other with injection pipe 33, regulate flow with control valve 35 during work, rechargable battery 31 is powered to motor, and the 32nd, circuit control panel, 34,34 ' be operating button.
The utility model is applicable to the various electrodynamic type sprayers of equipment.
