Description
Technical field
The present invention relates to agricultural machinery equipment technical field, specifically a kind of mini-size tillage machine crank-linkage type lifting device of agricultural machine.
Background technology
Mini-size tillage machine has structure simply, easy to operate advantage due to it, and at China's wide geographic area, particularly find broad application in southwest and some knobs.But because mini-size tillage machine volume structure is little, its space that can arrange is also less, causes a lot of common farm machinery not directly to be arranged on mini-size tillage machine, therefore, limit the scope of application of itself.More particularly have requirement miniature rotary cultivator to tilling depth, in order to meet its requirement to the rotary tillage degree of depth, many producers mini-size tillage machine do heavier, rely on the gravity of mini-size tillage machine self to meet the requirement of tilling depth; Now commercially directly two of mini-size tillage machine road wheels are directly removed in addition, walking axle fills the rotary tilling-type mini-size tillage machine of rotary tillage machine, although this way meets the requirement of tilling depth, when cultivating the two ends of ploughing, owing to there is no the support of road wheel, rotary tillage machine cannot promote, and needing people for lifting, wasting time and energy, and operation inconvenience, and this mini-size tillage machine can only configure a kind of single farm machinery, and function is comparatively single, can not meet the job requirements of agricultural diversification.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of novel mini-size tillage machine crank-linkage type lifting device of agricultural machine, realize the suspension arrangements of multiple different farm machinery on mini-size tillage machine, the free portable lifting of farm machinery and effective control of tilling depth, and then reduction labour intensity, improve farming efficiency.
The present invention is for solving the problems of the technologies described above, the technical scheme adopted is: a kind of mini-size tillage machine crank-linkage type lifting device of agricultural machine, comprise farm machinery, frame and the lift lever be arranged in frame, cranked rod and latch hook frame, one end of described farm machinery is hinged in frame, farm machinery are also provided with a connecting rod, described lift lever is all fixedly connected with a rotating shaft be arranged in frame with one end of cranked rod, the end of cranked rod is hinged with an intermediate bar, this intermediate bar is hinged with the connecting rod be arranged on farm machinery, farm machinery lifting can be driven by the interlock of cranked rod and intermediate bar when described lift lever rotates,
Described latch hook frame is provided with a spacing latch hook, cranked rod is provided with the fixed pin shaft that latch hook spacing with this matches, the top of described lift lever is provided with an operating handle, this operating handle is connected with spacing latch hook by a bracing wire, and can control locking or unclamping of spacing latch hook and fixed pin shaft by bracing wire.
The back-moving spring of position when being provided with in described latch hook frame for driving spacing latch hook to return to locking after operating handle unclamps.
Beneficial effect:
1, because crank-linkage type mechanism also exists dead-centre position in the process of motion, therefore this device is effectively controlled tilling depth by the assurance of dead-centre position, device itself controls tilling depth without the need to relying on the own wt increasing rotary tillage farm machinery, and tilling depth is adjustable, good practical effect.
2, the present invention expands the function of mini-size tillage machine, as long as farm machinery there are suitable suspension arrangement just can be used for mounting other farm machinery and the adjustment completing the lifting to farm machinery.
3, the toggle that the present invention adopts belongs to common mechanism, and its structure is simple, low cost of manufacture, without the need to adopting complicated technique in process.
4, this apparatus structure is simple, reasonable in design, easy to operate, and user advances at control mini-size tillage machine and while turning to, can handle the lifting of these farm machinery easily and unload, and contributes to reducing labour intensity, enhances productivity.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail:
A kind of mini-size tillage machine crank-linkage type lifting device of agricultural machine, comprise farm machinery 1, frame 9 and the lift lever 2 be arranged in frame 9, cranked rod 6 and latch hook frame 8, one end of described farm machinery 1 is hinged in frame 9, farm machinery 1 are also provided with a connecting rod 101, described lift lever 2 and cranked rod 6 are arranged in frame 9 by an axis of rotation, and the rotation of lift lever 2 can drive the cranked rod 6 coaxial with it to move up and down, the end of cranked rod 6 is hinged with an intermediate bar 5, this intermediate bar 5 is hinged with the connecting rod 101 be arranged on farm machinery 1, farm machinery 1 can be driven to be elevated by the interlock of cranked rod 6 and intermediate bar 5 when described lift lever 2 rotates, described latch hook frame 8 is provided with a spacing latch hook 7, cranked rod 6 is provided with the fixed pin shaft that latch hook 7 spacing with this matches, the top of described lift lever 2 is provided with an operating handle 3, this operating handle 3 is connected with spacing latch hook 7 by a bracing wire 4, and locking or unclamping of spacing latch hook 7 and fixed pin shaft can be controlled by bracing wire 4, and then realize the lifting of farm machinery 1 or unload.The back-moving spring 801 of position when being provided with in described latch hook frame 8 for driving spacing latch hook 7 to return to locking after operating handle 3 unclamps.
A kind of mini-size tillage machine crank-linkage type lifting device of agricultural machine designed by the present invention is in concrete use procedure: when farm machinery are in off working state, the configuration of its anatomical connectivity and layout are as shown in Figure 1, now operating personnel can rotate up and lift lift lever, and manipulation operation handle makes it drive limiting lock to be hooked in lock hook seat and to rotate up by bracing wire, when the cranked rod coaxial with lift lever drives farm machinery to rise to suitable position by intermediate bar, unclamp operation handle, limiting lock is rotated down under being hooked in the elastic force effect of back-moving spring, lock with the fixed pin shaft on cranked rod, thus control farm machinery, prevent farm machinery from falling, complete lifting.
When farm machinery are in running order, the configuration of its anatomical connectivity and layout are as shown in Figure 2, the tilling depth that device can control as required and other requirement, operating handle on manipulation lift lever, make it drive limiting lock to be hooked in lock hook seat by bracing wire to rotate up, now, spacing latch hook leaves fixed pin shaft, operating personnel slowly can be rotated down and put down lift lever, and then unload farm machinery.When needs control tilling depth, intermediate bar and cranked rod are on same straight line, i.e. cranked rod and intermediate bar conllinear, now drive line angle is zero, utilizes the dead-centre position of body of rod mechanism can play the object controlling tilling depth.
Mini-size tillage machine crank-linkage type lifting device of agricultural machine of the present invention, expands the function of mini-size tillage machine, as long as farm machinery there are suitable suspension arrangement just can be used for mounting other farm machinery and the adjustment completing the lifting to farm machinery.The toggle that it adopts belongs to conventional mechanism, and structure is simple, low cost of manufacture.Utilizing the dead-centre position of body of rod mechanism in motion process effectively to control tilling depth, controlling tilling depth without the need to increasing the own wt of rotovator, practical and convenient.
