Abstract

The invention discloses a lifting interlocking device, and relates to the technical field of tillage machinery. The problem that when a walking tractor is at work and needs to be turned around, it takes a handler a large amount of physical strength to hold a handle and make the tractor walk is solved. According to the technical scheme, the lifting interlocking device comprises a connecting rod support, a connecting rod, a limiting plate, an upper hook, a connecting rod rear support, a return baffle, a shifting fork spanner, a rear seat, a rear wheel assembly, a rear seat and rear wheel connecting plate, pedals, a reset spring, a lower hook, a limiting column, a compression roller support and the like. The lifting interlocking device saves the strength for the handler particularly when the walking tractor is adopted for tillage.

Description

Lifting interlock

One, technical fields

The present invention is applied to primary tillage equipment technical field, more particularly to when using tilling land by hand tractor, can make operator more It is laborsaving.

Two, technical backgrounds

China's per capita area of cultivated farmland deficiency world average level 40%, has a large population and a few land, and soil pressure is very huge.China will In the year two thousand twenty Realization a Fairly Well-off Society in a all-around Way, grain must ensure self-sufficiency, and farmland issue is to be related to whole national society surely The root problem of fixed and sustainable development.But arable land security and quality safety are reduced year by year, arable land is the essence of land resource China, and during land farming, because China's topography and geomorphology complexity is various, have a big chunk soil, on large-scale agricultural machinery Do not go, hand tractor farming can only be used, people's is physical limited, work is run out of space for one day, and the health to people is caused very Major injury.Regarding to the issue above, a kind of lifting interlock is invented necessary to solve the above problems.

The three, content of the invention

The present invention in order to solve, hand tractor operationally, turn u-turn when.Operator is needed to go to drag with very great The problem that firmly handlebar is walked.So adopt the technical scheme that, including connecting rod rack, connecting rod, limiting plate, upper hook, after connecting rod Support, return baffle plate, shift fork spanner, back seat, rear wheel assembly, back seat and trailing wheel connecting plate, pedal, back-moving spring, lower draw-bar, Limited post, pressing roller holder etc. are constituted.

Four, are illustrated

The present invention is described in further detail below in conjunction with the accompanying drawings：

Fig. 1 are present invention structural representations in working order.

Fig. 2 are present invention structural representations in a non-operative state, including walking and turn u-turn when state.

In figure；1. ploughshare mounting bracket, 2. connecting rod rack, 3. limiting plate, 4, connecting rod, 5. oblique support arm, 6. on link up with, 7. connect Bar after-poppet, 8. return baffle plate, 9. shift fork spanner, 10. back seat bearing chamber, 11. nylon sleeves, 12. pressing roller holders, 13. back seats, 14. spring arm-ties, 15. back-moving springs, 16. back seats and trailing wheel connecting plate, 17. return levers, 18. back seat vertical shafts, 19. land wheels, 20. wheel forks, 21. pedals, 22. lower draw-bars, 23. limited posts.

Five, specific embodiments

Referring to the drawings 1,2, ploughshare mounting bracket (1) is firmly welded with connecting rod rack (2), with connecting rod (4) limiting plate (3) axle Formula flexible connection, oblique support arm (5) is firmly welded with connecting rod rack (2), and upper hook (6) is movable with connecting rod after-poppet (7) internal-axis type Link, connecting rod after-poppet (7) is flexibly connected with connecting rod rack (2) by connecting rod (4) shaft type, return baffle plate (8) and pedal (21) it is flexibly connected with connecting rod after-poppet (7) shaft type installed in limiting plate (3) upper shift fork spanner (9) with bolt, back seat vertical shaft axle Room (10) is held by connecting plate and back seat, trailing wheel connecting plate is tightened together with bolt.Pressing roller holder (12) and back seat, trailing wheel connect Fishplate bar (16) is fastened with bolt.Back seat (13) is fastened by support and connecting plate (16) with bolt, and spring arm-tie (14) uses bolt Fastened with back seat rack.Back seat is firmly welded with trailing wheel connecting plate (16) and connecting rod after-poppet, and return lever (17) stands with back seat Axle (18) is fastened with screw, and wheel fork (20) is welded with back seat vertical shaft (18).Limited post (23) is firmly welded with wheel fork, Lower draw-bar (22) is flexibly connected with connecting rod after-poppet (7) internal-axis type.

Referring to the drawings described in 1. it, upper hook (6) is engaged with connecting rod rack upper end, is now working condition, when pushing away forward Hook is disengaged with connecting rod rack on during dynamic shift fork spanner (9), pedal (21) connecting rod rack (2) lifting is pressed downward, when lifting is arrived During top dead centre, lower draw-bar (22) hangs up automatically with connecting rod rack (2) lower end, as shown in accompanying drawing 2..

Referring to the drawings described in 2 it, connecting rod rack (2) rises to top dead centre, and limiting plate (3) drives pedal (21) return gear Plate (8) is bottomed out, and is disengaged with limited post (23), and land wheel (19) is free to rotate with wheel fork.

Claims

1. a kind of to lift interlock, it is by connecting rod rack (2), limiting plate (3), connecting rod (4), upper hook (6), connecting rod after-poppet (7), return baffle plate (8) shift fork spanner (9), back seat (13), spring arm-tie (14), back-moving spring (15), back seat is connected with trailing wheel Plate (16), return pin thick stick (17), back seat vertical shaft (18), land wheel (19), wheel fork (20), pedal (21), lower draw-bar (22), limit Position post (23) is constituted.Characterized in that, when moving shift fork spanner (9) forward, upper hook (6) disengages with connecting rod rack (2), uses pin Stepping on pedal (21) connecting rod rack (2) downwards can rise, and when being raised to top dead centre, lower draw-bar (22) is with connecting rod rack (2) lower end certainly Dynamic to hang up, limiting plate (3) is disengaged with limited post (23), and land wheel (19) can freely be turned round by vertical shaft (18).Shift fork is moved backward Spanner (9), lower draw-bar (22) is disengaged with connecting rod rack (2), and connecting rod rack (2) declines, and upper hook (6) is with connecting rod rack upper end certainly Dynamic to hang up, limiting plate (3) outer rim drives pedal (21) return baffle plate (8) to rise, to top dead centre.
