Abstract
The utility model discloses a water pump of a pesticide sprayer, comprising a pump body, a drive shaft and a driven shaft which are parallel, are arranged in the pump, a drive wheel and a driven wheel are respectively sleeved on the drive shaft and the driven shaft, and a front cover of the pump body is arranged on the front end plane of the drive wheel and the driven wheel. The beneficial effects of the water pump of the utility model reside in that: the pump body structure is simplified, the front cover is directly arranged on the front end of the drive wheel and the driven wheel, and practical volume of the pump body is increased and stabilized, thereby raising and stabilizing an injection distance.
Description
Technical field
The utility model relates to a kind of water pump, especially the water pump of pesticide sprayer.
Background technique
at present, in the manufacturing industry of pesticide sprayer, especially the water pump of sprayer, usually require bulk range can reach 8 ~ 10 meters, to complete comparatively stable pesticide spraying task, and the key that determines this performance is that water pump is pump body structure, the water pump that uses traditionally adopts the pump housing of gear type, the oil sucting cavity space of rotarily driving by gear increases, agricultural chemicals in pesticide sprayer is entered in the pump housing, again the agricultural chemicals of between cog is squeezed out the pump housing and sprays insecticide, and in actual use, because the pump body spatial placement is not very reasonable, cause uptake unstable, thereby affect bulk range.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of water pump of pesticide sprayer, possesses the internal structure of comparatively simplifying, and improves the pump housing and absorbs stability.
The utility model is achieved through the following technical solutions.
A kind of water pump of pesticide sprayer comprises the pump housing, is provided with the driving shaft and the driven shaft that be arranged in parallel in the above-mentioned pump housing, is respectively installed with driving wheel and follower, and the protecgulum of the above-mentioned pump housing is arranged on the front-end face of principal and subordinate wheel.
Further, be provided with seal ring between above-mentioned driving wheel, follower front-end face and above-mentioned protecgulum.
The beneficial effects of the utility model are, have simplified pump body structure, protecgulum are set directly at the front end of principal and subordinate wheel, have increased and stablized the actual volume amount of the pump housing, thereby have improved and stablized the distance of spraying.
Description of drawings
Fig. 1 is the structural representation of the water pump of the utility model pesticide sprayer.
Embodiment
The below is described in further detail the utility model according to drawings and embodiments.
Fig. 1 is the structural representation of the water pump of the utility model pesticide sprayer, with reference to Fig. 1, the utility model, the water pump of pesticide sprayer, comprise the pump housing 10, the pump housing 10 front end and back end are respectively protecgulum 12 and bonnet 14, are provided with the driving shaft 160 and the driven shaft 180 that be arranged in parallel in the above-mentioned pump housing 10, be respectively installed with driving wheel 16 and follower 18, the protecgulum 12 of the above-mentioned pump housing 10 is arranged on the front-end face of principal and subordinate wheel 16.
Further, be provided with seal ring 100 between above-mentioned driving wheel 16, follower 18 front-end faces and above-mentioned protecgulum 12, the leakage that seal ring 100 can effectively prevent agricultural chemicals is set, improved the sealability of the pump housing 10.
The utility model, the water pump of pesticide sprayer has been simplified pump body structure, protecgulum is set directly at the front end of principal and subordinate wheel, has increased and stablized the actual volume amount of the pump housing, thereby has improved and stablized the distance of spraying.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this art can understand the utility model content and be implemented, and can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
