Abstract
The invention relates to a hydraulic oil pump for a walking rice transplanter, which is mounted a rice transplanting mechanism and comprises a hydraulic oil pump housing, wherein a hydraulic intermediate plate is arranged on the hydraulic oil pump housing; a hydraulic side plate is arranged on the hydraulic intermediate plate; the hydraulic oil pump housing is internally provided with a first gear and a second gear; the first gear is engaged with the second gear; a first gear shaft of the first gear is located on the hydraulic oil pump housing and a gear hole of the hydraulic intermediate plate; one end of a second gear shaft of the second gear is located on the hydraulic oil pump housing and the other end thereof penetrates through the hydraulic intermediate plate, and is located on the hydraulic side plate; a connector extends out; a connecting shaft is arranged on the hydraulic oil pump housing; three top oil holes are inwards formed at the top end of the hydraulic intermediate plate; and a side oil hole communicated with the three top oil holes at the top end is formed on the side of the hydraulic intermediate plate. With the adoption of the structure, lubricating oil can be added to the gears in the hydraulic oil pump conveniently due to the oil holes, the wear-proof property of the hydraulic oil pump is better, the service life of the hydraulic oil pump is prolonged, and the hydraulic oil pump is more convenient to use.
Description
Technical field
The present invention relates to the hand-held transplanter in the farm machinery industry, especially relate to a kind of hand-held transplanter hydraulic-pressure pump.
Background technique
At present, in the farm machinery industry, it is the most extensive that hand-held transplanter uses, owing to be in field work, in rice transplanting, be easy to contact water and machine is easy to rub, because hydraulic-pressure pump will connect rice transplanting mechanism, can be easy to backwater rust corrosion and friction terribly, so just need to adopt the material of abrasion-proof corrosion-proof to make, yet present this cost of material is too high, is not suitable for using; And the lubricant oil on the internal gear is inconvenient to add, and is inconvenient to produce, and reduced manufacturing efficiency.
Summary of the invention
Technical problem to be solved by this invention provides a kind of hand-held transplanter hydraulic-pressure pump that is difficult for friction and convenient interpolation lubricant oil that is not easy to corrode.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hand-held transplanter hydraulic-pressure pump, be installed on the rice transplanting mechanism, comprise the hydraulic-pressure pump housing, be provided with the hydraulic pressure intermediate plate at the hydraulic-pressure pump housing, be provided with the hydraulic pressure side plate at the hydraulic pressure intermediate plate, be provided with the first gear and the second gear in the described hydraulic-pressure pump housing, the first gear and the engagement of the second gear; The first gear shaft of the first gear is positioned on the gear hole of hydraulic-pressure pump housing and hydraulic pressure intermediate plate; The second gear shaft one end of the second gear is positioned on the hydraulic-pressure pump housing, and the other end runs through the hydraulic pressure intermediate plate and is positioned on the hydraulic pressure side plate and stretches out connecting head; Be provided with coupling shaft at the hydraulic-pressure pump housing; Hydraulic pressure intermediate plate top inwardly offers three top oilholes, and is provided with three top oilholes that the side oilhole is communicated with the top at side opening.
Further concrete, the tooth on described the first gear is positioned at the middle part of the first gear shaft; Tooth on the second gear is positioned at 2/3 place of the second gear shaft and cooperates with tooth on the first gear.
Further concrete, described hydraulic pressure intermediate plate and hydraulic pressure side plate adopt the material of aluminium, silica and magnesium to mix and make.
The invention has the beneficial effects as follows: adopted after the said structure, adopted oilhole conveniently to add lubricant oil to the gear in the hydraulic-pressure pump, and its wear-resisting property has been better, has increased its working life, more convenient to use.
