Abstract
The invention discloses a harvesting-machine lifting device of a walking-type harvester. The harvesting-machine lifting device is characterized in that a rack cavity is arranged in a shell, a rack is slidably arranged in the rack cavity, and the connecting end of the rack extends out of the shell; a gear cavity is arranged in the shell and is communicated with the rack cavity, a gear meshed with a rack is arranged in the gear cavity, the axis of the gear is perpendicular to the rack, and a turning handle extending out of the shell is coaxially fixed on the gear; the shell is further internally provided with a pressure plate pressing the gear on the rack, a sealing cover is arranged on the shell, and a pressure spring is arranged between the sealing cover and the pressure plate. The harvesting-machine lifting device is fixed on a frame, the gear is rotated through the turning handle, and the gear is enabled to rotate axially; due to the fact that the gear is meshed with the rack, the rack is driven to move by rotating of the gear; the end of the rack extends out of the shell to form the connecting end, a harvesting machine can be pushed to move vertically by moving of the rack, and the lifting function of the harvesting machine is realized.
Description
Technical field
The present invention relates to a kind of mechanical lifting gear, be specifically related to a kind of harvester elevator of walking type reaping machine.
Background technology
Grain header is the machinery of integration harvesting crops.Walking type reaping machine is generally provided with dynamical system, can realize from walking.Artificial hand steered operation is adopted, the adjustment of travel direction during use.Walking type reaping machine disposablely can complete harvesting, threshing operation.The reaping apparatus of walking type reaping machine is the vitals of whole body, serves the effect of harvesting and preliminary threshing.Regulate because reaping apparatus needs to carry out height according to the growing height of crops.Regulative mode conventional at present adopts stay cord to carry out lift to regulate.For this regulative mode, stay cord is outside exposed on the one hand, in use weares and teares comparatively large, easily causes potential safety hazard when Long-Time Service is not changed in time.On the other hand, the hardness of stay cord is lower, can not be used as support component, therefore when harvester is subject to active force upwards, easily beat, the efficiency of impact harvesting.
Summary of the invention
The object of the present invention is to provide a kind of harvester elevator of walking type reaping machine, effectively can be elevated harvester, and the position that can limit harvester supports, prevent harvester generation bob in use.
For achieving the above object, technical scheme of the present invention is: the harvester elevator of walking type reaping machine, comprises housing, is provided with a rack chamber in described housing, and sliding in described rack chamber is provided with a tooth bar, and the link of described tooth bar stretches out outside housing; Be provided with a gear cavity in described housing, described gear cavity is communicated with rack chamber, and be provided with one and tooth bar meshed gears in described gear cavity, the axis of described gear is vertical with tooth bar, described gear is coaxially fixed with the turning handle stretching out housing; Also be provided with a pressing plate be pressed on by gear on tooth bar in described housing, described housing is provided with seal cover, is provided with stage clip between described seal cover and pressing plate.
When adopting technique scheme, the present invention is fixed in frame, by turning handle transmitting gear, makes gear around its axial rotation.Due to wheel and rack engagement, under the rotation of gear, carry-over bar is with to move.End due to tooth bar is stretched out housing and is formed link, can promote moving up and down of harvester, achieve the elevating function of harvester by the mobile of tooth bar.Moreover because the kind of drive reliability of rack-and-pinion is higher, the possibility broken down is less, safe and reliable.After the lifting completing harvester, by the locking device of peripheral hardware, rack position can be fixed, make harvester can in working order time be in fixing state, upper and lower play when being placed on harvesting, the effect of impact harvesting.
Further, link and the housing junction of described tooth bar are provided with dust cap, are provided with oil sealing between described dust cap and rack chamber.This setting can effectively play dust-proof effect, and can prevent leakage of oil, and forms good lubrication.
Further, described seal cover has been threaded an adjusting bolt, and the end of described adjusting bolt contacts with pressing plate.This setting can change pressure to stage clip by the position of adjusting bolt, thus the impaction state of adjustment gear.
Further, described gear cavity is vertical with rack chamber.This setting at utmost can utilize space, and reliability when improving gear and tooth bar use.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the harvester elevator embodiment of walking type reaping machine of the present invention.
Embodiment
As shown in Figure 1, the harvester elevator of walking type reaping machine of the present invention, comprises housing 1, and be provided with a rack chamber in housing 1, gear cavity is vertical with rack chamber.This setting at utmost can utilize space, and improves reliability when gear 3 and tooth bar 2 use.Slide in rack chamber and be provided with a tooth bar 2, the link of tooth bar 2 stretches out outside housing 1; Link and housing 1 junction of tooth bar 2 are provided with dust cap 21, are provided with oil sealing between dust cap 21 and tooth bar 2 chamber.This setting can effectively play dust-proof effect, and can prevent leakage of oil, and forms good lubrication.Be provided with a gear cavity in housing 1, gear cavity is communicated with tooth bar 2 chamber, and be provided with one and tooth bar 2 meshed gears 3 in gear cavity, the axis of gear 3 is vertical with tooth bar 2, gear 3 is coaxially fixed with the turning handle stretching out housing 1; Also be provided with a pressing plate 4 be pressed on by gear 3 on tooth bar 2 in housing 1, housing 1 is provided with seal cover 5, is provided with stage clip 6 between seal cover 5 and pressing plate 4.Seal cover 5 has been threaded an adjusting bolt 51, and the end of adjusting bolt 51 contacts with pressing plate 4.This setting can change pressure to stage clip 6 by the position of adjusting bolt 51, thus the impaction state of adjustment gear 3.
The present invention is fixed in frame, by turning handle transmitting gear 3, makes gear 3 around its axial rotation.Because gear 3 engages with tooth bar 2, under the rotation of gear 3, carry-over bar 2 is with to move.End due to tooth bar 2 is stretched out housing 1 and is formed link, can promote moving up and down of harvester, achieve the elevating function of harvester by the mobile of tooth bar 2.Moreover because the kind of drive reliability of gear 3 tooth bar 2 is higher, the possibility broken down is less, safe and reliable.After the lifting completing harvester, by the locking device of peripheral hardware, tooth bar 2 position can be fixed, make harvester can in working order time be in fixing state, upper and lower play when being placed on harvesting, the effect of impact harvesting.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
