Abstract
The invention discloses a power drive structure for a harvesting platform of a backpack corn harvester. The power drive structure belongs to agricultural machinery. A stalk smashing moving cutter drive shaft, a stem pulling and ear picking roll power drive shaft, a fruit cluster conveying auger and conveying chain harrow power drive shaft and a power input shaft are arranged at the left side part, the front side part, the right side part and the back side part of a reversing speed change gear main box respectively; a slave jaw is fixedly mounted on the power input shaft; a driving jaw is rotatablely matched with the power input shaft in a sleeving manner; the slave jaw is connected and matched with the driving jaw in a clamping manner; a pressure spring, a stop sheet and a pressure adjustment nut are assembled and mounted on the power input shaft in sequence and positioned in a center hole of the driving jaw; a connecting plate is fixedly mounted on the back end face of the driving jaw by fastening screws; and a universal joint transmission shaft is fixedly mounted on the connecting plate. The power drive structure is novel and reasonable in structural design, simple and compact in structure, reliable in transmission, good in safety and low in failure rate, and damages of spare parts of a machine tool can be avoided and eliminated effectively.
Description
Technical field
The invention belongs to agricultural machinery, relates generally to a kind of Backpack-type maize harvester header power drive structure of using with four-wheel tractor.
Background technology
Because the defective in the existing Backpack-type maize harvester master-plan, the motion-promotion force that stalk disintegrating moving knife on its facility, stem pulling snapping bar and fruit ear are carried screw feeder and carried chain harrow is respectively by three independent gear-box transmission driving power separately that arrange, and complex structure, manufacturing cost height, weight are greatly to be badly in need of solving the ground technical problem.Simultaneously, in the power drive system of existing facility, Overload Protection mechanism is not installed, when working load exceeds the security intensity that the facility design can bear; facility very easily occur damage fault, even cause personal injury, maintenance cost increases; operating efficiency reduces, poor stability.
Summary of the invention
The purpose of the invention is exactly the problem that exists for above-mentioned prior art; design provides a kind of Backpack-type maize harvester header power drive structure of new construction; by adopting a commutation change-speed gearing header tank to bear stalk disintegrating moving knife, stem pulling snapping bar and fruit ear conveying screw feeder and the technical scheme that one of conveying chain harrow drives three power drive transmission and equipped castellated overload protection arrangement, reach the purpose of simplifying implement structure, raising security performance, the operation fault that reduces, reduction maintenance cost.
The purpose of the invention is achieved in that stalk disintegrating moving knife driving shaft, stem pulling snapping bar Power Available Shaft, fruit ear conveying screw feeder and carrier chain raking power driving shaft and power input shaft is set respectively on left side, front side, right side and the rear side position of commutation change-speed gearing header tank; Be fixedly mounted with from dynamic interlocking teeth at power input shaft, active jaw overlaps rotationally and fits on the power input shaft, described active jaw with cooperate from the dynamic interlocking teeth clamping, on power input shaft, be positioned at active jaw centre bore from front to back successively equipped compression spring, catch and look nut, the front and rear end of described compression spring contacts cooperation with active jaw respectively with catch; By trip bolt connecting plate is packed on the active jaw rear end face, is fixedly mounted with Cardan shaft at connecting plate, so far consist of Backpack-type maize harvester header power drive structure.·
The invention is rationally novel in design, and is simple and compact for structure, lightweight, reliable transmission, and safety is good, and the damage of facility parts can effectively be avoided and eliminate to failure rate is low.
Description of drawings
Accompanying drawing is Backpack-type maize harvester header power drive structure collectivity structural representation.
Piece number explanation among the figure:
1, commutation change-speed gearing header tank, 2, stem pulling snapping bar Power Available Shaft, 3, fruit ear carry screw feeder and carrier chain raking power driving shaft, 4, stalk disintegrating moving knife driving shaft, 5, from dynamic interlocking teeth, 6, power input shaft, 7, active jaw, 8, compression spring, 9, catch, 10, look nut, 11, trip bolt, 12, connecting plate, 13, Cardan shaft.
Embodiment
Below in conjunction with accompanying drawing the invention embodiment is described in detail.A kind of Backpack-type maize harvester header power drive structure arranges respectively stalk disintegrating moving knife driving shaft 4, stem pulling snapping bar Power Available Shaft 2, fruit ear conveying screw feeder and carrier chain raking power driving shaft 3 and power input shaft 6 on left side, front side, right side and the rear side position of commutation change-speed gearing header tank 1; Be fixedly mounted with from dynamic interlocking teeth 5 at power input shaft 6, active jaw 7 overlaps rotationally and fits on the power input shaft 6, described active jaw 7 with cooperate from dynamic interlocking teeth 5 clampings, on power input shaft 6, be positioned at active jaw 7 centre bores from front to back successively equipped compression spring 8, catch 9 and look nut 10, the front and rear end of described compression spring 8 contacts cooperation with active jaw 7 with catch 9 respectively; By trip bolt 11 connecting plate 12 is packed on active jaw 7 rear end faces, is fixedly mounted with Cardan shaft 13 at connecting plate 12.
During operation, the main transmission of Backpack-type maize harvester drives Cardan shaft 13 rotations, through connecting plate 12, trip bolt 11, active jaw 7, drive power input shafts 6 from dynamic interlocking teeth 5 and rotate, the stem pulling snapping bar Power Available Shaft 2, the fruit ear that drive respectively behind commutation change-speed gearing header tank 1 in the ceding of Taiwan are carried screw feeder and carrier chain raking power driving shaft 3 and 4 rotations of stalk disintegrating moving knife driving shaft, finish the transmission of power operation of driving for a case three.When the header total load surpasses the facility security intensity, power input shaft 6 and stop operating from dynamic interlocking teeth 5, this moment is under the dental inlay from dynamic interlocking teeth 5 promotes, active jaw 7 moves axially, compression pressure spring 8, lead, broken away from the clampings cooperation by dynamic interlocking teeth 7,5, active jaw 7 is avoided ceding of Taiwan operation damage of components in power input shaft 6 idle running.Behind the excess load Failure elimination, main, by dynamic interlocking teeth 7,5 under compression spring 8 effects, automatically recover clamping and cooperate, carry out normal operation.
