Abstract
The utility model relates to an agricultural implement which is a star gear spray pump which is characterized in that a rotor star gear is composed of a passive star gear which is made into an inner pentagon cavity body and an active star gear which is made into an outer quadrangle gear. A pump shaft and a shaft core of the active star gear are in an identical shaft core. A shaft core of the passive star gear and the shaft core of the active star gear are deviated. Water sucked by a suction chamber is delivered into a spray head along a discharge cavity under the pressure of the active star gear and the passive star gear and is sprayed out in a fog shape. The utility model has the advantages of simple manufacturing technique, low cost, simple operation, high work efficiency and high safety.
Description
The utility model relates to the supporting agricultural machinery and implement of farm tractor, based on machinery-a kind of star spraying gear pump of the prevention and control of plant diseases, pest control.
Spray affair device of the prior art has manually, the back carried sprayer, all makes to annotate plug pump principle, and its main deficiency is shower nozzle of a sprayer, manual lever, and very heavy, efficient is low, and labor intensity is big, causes deinsectization, weed eradication people to poison easily.
The purpose of this utility model is to solve deficiency in the above-mentioned prior art, and a kind of star spraying gear pump is provided, and with the supporting use of farm tractor, removes the hardship that the peasant carries sprayer on the body, raise the efficiency 20 surplus times, be particularly conducive to operation in flakes.
The purpose of this utility model reaches in the following manner, as shown in the figure, a kind of star spraying gear pump, by the pump housing 5, pump shaft 3, rotor star gear 4, inhale chamber 1, row chamber 6 compositions such as grade, it is characterized in that rotor star gear 4 is pentagon cavitys in being by passive star gear 4-1, initiatively star gear 4-2 is outer tetragonal gear composition, passive star gear 4-1 interior angle is tangent with the exterior angle of active star gear 4-2, it is equal and opposite in direction, pump shaft 3 is with initiatively star gear axis 20 is on same axle center, and passive star gear axis 19 departs from mutually with active star gear axis 20.
A kind of star spraying gear pump is characterized in that pump shaft 3 and the axle center 20 of star gear 4-2 initiatively are to be fixedly connected, and inhales chamber 1 and passes the pump housing 5 in a tubular form and communicate with rotor star gear 4, arranges chamber 6 and passes the pump housing 5 from rotor star gear 4 in a tubular form and connect with shower nozzle.
A kind of star spraying gear pump is characterized in that pump seat frame 18 is fixed on the tractor, and one in tractor links by vee belt and vee-pulley 13.
The utility model has following advantage compared to existing technology:
1. the supporting use of this atomizing pump and farm tractor can be installed a plurality of shower nozzles on the pump, alleviates peasant's labor intensity, increases work efficiency surplus in the of 20 times.
2. in flakes on the prevention and control of plant diseases, pest control on ground, this atomizing pump can all be finished the operation of spray medicine, good bug eliminating effect at short notice.
3. this atomizing pump manufacturing process is simple, and cost is low, and is simple to operate, safe and reliable.
The explanation of accompanying drawing drawing:
Fig. 1 is a star spraying gear pump assembling section.
Fig. 2 is a star spraying gear pump schematic diagram.
Among the above figure: 1-inhales initiatively star gear axis of chamber, 2-pump cover, 3-pump shaft, 4-rotor star gear, the 5-pump housing, 6-row chamber, sieve's 7-bolt, 8-pin, 9-mechanical seal, 10-transmission shaft, 11-bearing, 12-gland and sieve bolt, 13-vee-pulley, 14-key, sieve's 15-bolt, 16-ring washer, 17-oil sealing, 18-pump seat frame, the passive star gear axis of 19-, 20-, and the passive star gear of 4-1,4-2 be the star gear initiatively.
The utility model is described in further detail below in conjunction with accompanying drawing: this atomizing pump mainly is divided into two-part, first portion is a mist pump part, adopt the gear pump principle, it is to adopt the fine finishing of wear-resisting anti-rotten steel material to form that rotor 4 is arranged in the pump housing 5, tightly cooperate with the pump housing, initiatively star gear 4-2 rotation and drive passive star gear 4-1, when rotor 4 high speed rotating, suck liquid through rotating compressed liquid by inhaling chamber 1 with 4-2 and 4-1 between cog, liquid is sent into shower nozzle by row chamber 6, each tooth cavity is all finished same movement process successively, and pump just can continuous draining like this, and the work of spraying is finished in the atomization of liquid.Second portion is a drive part, it is made up of parts such as pump seat frame 18, mechanical seal 9, transmission shaft 10, bearing 11, vee-pulleys 13, it mainly acts on is that pump is installed on the farm tractor, by the transmission of speedup vee-pulley, farm tractor power is passed to atomizing pump, reach the running purpose, wherein mechanical seal is reliably tight, prevent drainage, avoid liquid waste, this pump is because by the belt wheel speedup, thereby available minimum throttle obtains higher atomisation pressure, the atomization of liquid is good, reaches fuel-economizing, economizes the purpose of liquid, synergy.
