Abstract
A driving structure for a gear pump of a walking motor-driven rice transplanter belongs to agricultural machinery and is characterized in that bearing seats are assembled on a gear pump housing; two bearings are arranged in the bearing seats; a power input shaft is inserted in two bearing bores in a matching way; one end of the power input shaft is in claw coupling with one end of a main gear shaft; and a drive pulley is fixedly arranged at the end of the power input shaft arranged at the outer side of the bearing seat. The driving structure has the advantages of simple structure, reasonable power transfer and stressing, good lubricating condition, long service life of parts, few operation breakdowns and reliable use.
Description
Technical field
The utility model belongs to farm machinery, relates generally to the Working mechanism on the hand steered motor-driven transplanting equipment.
Background technique
At present, the gear pump that is installed on the hand-held automotive transplanter all is that power input shaft and main gear shaft are the structure of one, and promptly diaxon is a stiff shaft, and directly installs to cooperate between gear pump case and the major and minor gear shaft and contact, do not establish oil leab again, the pocketed oil district occurs.In actual production is used, because the suffered lateral force of drive pulley acts directly on the main gear shaft, the existence in pocketed oil district in addition, gear pump major and minor gear shaft clamping stagnation, aggravation wearing and tearing and gear pump body often occur and sweeps technical faults such as thorax, reduce the utilization efficiency and the working life of facility, increased operating cost.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at above-mentioned prior art, design provides a kind of hand-held automotive transplanter gear pump driven structure, and the transmission, the elimination pocketed oil district that reach lateral force when overcoming the operation of gear pump driven belt pulley produce, improve lubricating condition, alleviate parts wear, prolong the gear pump purpose in working life.
Basic design of the present utility model is, a kind of hand-held automotive transplanter gear pump driven structure comprises gear pump case and equipped main gear shaft, pinion axle, equipped bearing support on the outside end face of gear pump case, two Bearing Installation are in bearing support inside, the power input shaft inserting is in two brearing bores, the inner end portion of power input shaft is connected with the tooth embedding of main gear shaft outer end, installs drive pulley on the end outside power input shaft is positioned at bearing support.Be provided with oil leab on gear pump case, be provided with lubricant reservoir between main gear shaft and pinion axle outer end and gear pump case internal face, the two ends of oil leab are communicated with lubricant reservoir and fuel tank respectively.Equipped wear-resistant sleeve between main gear shaft, pinion axle and gear pump case.
The utility model adopts main gear shaft and power input shaft to divide body structure, configuration is installed wear-resistant sleeve and is set up oil leab, eliminate the technological deficiency that the conventional tooth wheel pump exists, have simple in structure, transmission is stressed rationally, lubricate, parts long service life, characteristics that fault is few.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the utility model is described in detail.A kind of hand-held automotive transplanter gear pump driven structure comprises gear pump case 5 and equipped main gear shaft 2, pinion axle 3, equipped bearing support 9 on gear pump case 5 outside end faces, two bearings 11 are installed in bearing support 9 inside, power input shaft 8 insertings are in two bearing 11 endoporus, the inner end portion of power input shaft 8 is connected with main gear shaft 2 outer end tooth embeddings, is positioned at power input shaft 8 on the end in bearing support 9 outsides to install drive pulley 7.Be provided with oil leab 10 on gear pump case 5, be provided with lubricant reservoir 6 between main gear shaft 2 and pinion axle 3 outer ends and gear pump case 5 internal faces, the two ends of oil leab 10 are communicated with lubricant reservoir 6 and fuel tank 1 respectively.Equipped wear-resistant sleeve 4 between main gear shaft 2, pinion axle 3 and gear pump case 5.
During operation, gear pump case 5 is installed on the fuel tank 1, the drive pulley 7 of rotation is given main gear shaft 2 with rotating power through power input shaft 8 transmissions, and drives pinion axle 3 rotation relatively, finishes the gear pump operation.Two bearings 11 have been eliminated the transmission of drive pulley 7 lateral forces, and oil leab 10 has guaranteed the lubricated needs of major and minor gear shaft 2,3, have avoided the formation in pocketed oil district, have improved lubricating condition, the installation of wear-resistant sleeve 4, the working life of having improved gear pump.
