Description
Technical field
The present invention relates to agricultural machinery equipment technical field, a kind of tiller crank-linkage type lifting device of agricultural machine.
Background technology
Tiller has simple in construction, easy to operate advantage due to it, and at China's wide geographic area, find broad application in particularly southwest and some knobs.But owing to tiller volume structure is little, its space that can arrange is the least, causes a lot of common farm machinery can not be directly arranged on tiller, therefore, limit the range of itself.More particularly tilling depth is required miniature rotary cultivator, in order to meet its requirement to the rotary tillage degree of depth, many producers tiller do heavier, rely on the gravity of tiller self to meet the requirement of tilling depth；Also have currently on the market and directly the two of tiller road wheels are directly removed, walking axle fills the rotary tilling-type tiller of rotary tillage machine, although this way meets the requirement of tilling depth, but when cultivating the two ends ploughed, owing to there is no the support of road wheel, rotary tillage machine cannot promote, and needs artificially to lift, wastes time and energy, and operation inconvenience, and this tiller can only configure a kind of single agricultural machinery and implement, and function is the most single, it is impossible to meets 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 tiller crank-linkage type lifting device of agricultural machine, realize the multiple different suspension arrangements of agricultural machinery and implement on tiller, the free portable of agricultural machinery and implement promotes and effective control of tilling depth, and then reduction labor intensity, improve farming efficiency.
The present invention solves above-mentioned technical problem, be the technical scheme is that a kind of tiller crank-linkage type lifting device of agricultural machine, including agricultural machinery and implement, frame and the lift lever being arranged in frame, toggle-action lever and latch hook frame, one end of described agricultural machinery and implement is hinged in frame, a connecting rod it is additionally provided with on agricultural machinery and implement, one end of described lift lever and toggle-action lever is all fixing with a rotating shaft being arranged in frame to be connected, the end of toggle-action lever is hinged with an intermediate bar, this intermediate bar is hinged with the connecting rod being arranged on agricultural machinery and implement, agricultural machinery and implement can be driven to lift by the linkage of toggle-action lever and intermediate bar when described lift lever rotates；
A spacing latch hook it is provided with on described latch hook frame, toggle-action lever is provided with the fixed pin shaft matched with this spacing latch hook, 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.
It is provided with after unclamping at operating handle in described latch hook frame and drives spacing latch hook to recover to the back-moving spring of position during locking.
Beneficial effect:
1, during motion, there is dead-centre position due to crank-linkage type mechanism, therefore tilling depth is effectively controlled by this device by the assurance of dead-centre position, device itself is without relying on the own wt increasing rotary tillage agricultural machinery and implement to control tilling depth, and tilling depth is adjustable, good practical effect.
2, the present invention expands the function of tiller, as long as there being suitable suspension arrangement just to can be used to mount other agricultural machinery and implement and the regulation completing the lifting to agricultural machinery and implement on agricultural machinery and implement.
3, the toggle that the present invention uses belongs to common mechanism, its simple in construction, low cost of manufacture, without using complicated technique in the course of processing.
4, this apparatus structure is simple, reasonable in design, easy to operate, and user, while controlling tiller advance and turning to, can handle the lifting of these agricultural machinery and implement easily and drop, and contributes to reducing labor intensity, improves production efficiency.

Detailed description of the invention
The present invention will be further described in detail with specific embodiment below in conjunction with the accompanying drawings:
A kind of tiller crank-linkage type lifting device of agricultural machine, including agricultural machinery and implement 1, frame 9 and the lift lever 2 being arranged in frame 9, toggle-action lever 6 and latch hook frame 8, one end of described agricultural machinery and implement 1 is hinged in frame 9, a connecting rod 101 it is additionally provided with on agricultural machinery and implement 1, described lift lever 2 and toggle-action lever 6 are arranged in frame 9 by an axis of rotation, and the rotation of lift lever 2 can drive the toggle-action lever 6 being coaxial therewith to move up and down, the end of toggle-action lever 6 is hinged with an intermediate bar 5, this intermediate bar 5 is hinged with the connecting rod 101 being arranged on agricultural machinery and implement 1, agricultural machinery and implement 1 can be driven to lift by the linkage of toggle-action lever 6 and intermediate bar 5 when described lift lever 2 rotates；A spacing latch hook 7 it is provided with on described latch hook frame 8, toggle-action lever 6 is provided with the fixed pin shaft matched with this spacing latch hook 7, 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 can control locking or unclamping of spacing latch hook 7 and fixed pin shaft by bracing wire 4, and then realization to the lifting of agricultural machinery and implement 1 or drops.It is provided with after unclamping at operating handle 3 in described latch hook frame 8 and drives spacing latch hook 7 to recover to the back-moving spring 801 of position during locking.
A kind of tiller crank-linkage type lifting device of agricultural machine designed by the present invention is during specifically used: when agricultural machinery and implement are in off working state, its structure connects configuration with layout as shown in Figure 1, now operator can rotate up and lift lift lever, and manipulation operation handle is passed to bracing wire and drives limiting lock to rotate up in being hooked in lock hook seat, when the toggle-action lever coaxial with lift lever drives agricultural machinery and implement to rise to suitable position by intermediate bar, unclamp operating handle, limiting lock is hooked under the elastic force effect of back-moving spring and is rotated down, lock with the fixed pin shaft on toggle-action lever, thus control agricultural machinery and implement, prevent agricultural machinery and implement from falling, complete to promote.
When agricultural machinery and implement are in running order, its structure connects configuration with layout as shown in Figure 2, the tilling depth that device can control as required and other requirement, operating handle on manipulation lift lever, being passed to bracing wire drives limiting lock to rotate up in being hooked in lock hook seat, and now, spacing latch hook leaves fixed pin shaft, operator can slowly be rotated down and put down lift lever, and then drop agricultural machinery and implement.When needs control tilling depth, intermediate bar and toggle-action lever are on same straight line, i.e. toggle-action lever and intermediate bar conllinear, now drive line angle is zero, utilizes the dead-centre position of body of rod mechanism can play the purpose controlling tilling depth.
The tiller of present invention crank-linkage type lifting device of agricultural machine, expands the function of tiller, as long as there being suitable suspension arrangement just to can be used to mount other agricultural machinery and implement and the regulation completing the lifting to agricultural machinery and implement on agricultural machinery and implement.The toggle that it uses belongs to conventional mechanism, simple in construction, low cost of manufacture.Utilize body of rod mechanism dead-centre position in motor process that tilling depth is effectively controlled, it is not necessary to increase the own wt of rotary cultivator and control tilling depth, practical and convenient.
