Abstract
The invention provides a rotary tiller which comprises an agricultural transportation truck and a rotary tillage part hung on the tail portion of the transportation truck. The rotary tillage part comprises a rotary blade shaft arranged on a cantilever in a sleeved mode. A rotary blade is arranged on the rotary blade shaft. The rotary blade shaft and the rotary blade form an integrated die. The agricultural transportation truck comprises a rack. A steering wheel is arranged on the head portion of the rack. An engine, a hydraulic pump and an arc-shaped soil covering plate are fixed on the rack. An oil cylinder is connected to the hydraulic pump. The oil cylinder is hinged to the rotary tillage part. A hole through which the rotary blade shaft and the rotary blade can penetrate through is formed in the middle of the arc-shaped soil covering plate. A cab is arranged between the engine and the steering wheel. The rotary tiller has the advantages that the tillage depth is increased through increasing the radius of the rotary blade shaft, falling points of tillage soil are controlled through the arc-shaped soil covering plate, and the transmission structure used for enabling the rotary tillage part to be lifted up and fall down is changed into hydraulic transmission, so that the service life of the rotary tiller is increased, and personal safety can be well ensured.
Description
Technical field
The invention belongs to field of agricultural machinery, especially relates to a kind of by agricultural transportation vehicle and the supporting rotovator forming of rotary ploughing part.
Background technology
In existing technology, the operation principle of most of rotovators is to be rotated by belt driven gear case by the engine on agricultural transporting machine, gear-box rotates by chain-driving rotary ploughing cutter shaft again, thereby drives the rotary blade on rotary ploughing cutter shaft to carry out rotary tillage process to soil.Yet because rotovator volume is larger, rotary blade is less and be not with trailing bar, exists rotovator structure heaviness loose, the cultivated soil after the more shallow and rotary tillage of the rotary tillage degree of depth is complete is without technical problems such as fixing drop points.
Summary of the invention
The problem that the invention will solve is to provide a kind of rotovator, is especially applicable to the rotary tillage degree of depth and the crowd of having certain requirements that levels land.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of rotovator, comprise agricultural transportation vehicle and the rotary ploughing part that hangs on transport vehicle afterbody, rotary ploughing part comprises the rotary ploughing cutter shaft being enclosed within on cantilever, on rotary ploughing cutter shaft, have rotary blade, and rotary ploughing cutter shaft and rotary blade are integrated mould; Agricultural transportation vehicle comprises that head is with the frame of steering wheel, is fixed with engine and an arc trailing bar in frame, and there is an energy centre of arc trailing bar by the hole of rotary ploughing cutter shaft and rotary blade, between engine and steering wheel, is fixed with driver's seat.By strengthening rotary ploughing cutter shaft radius, increase tilling depth, by arc trailing bar, control and plough native drop point.
Rotovator also comprises the hydraulic pump being fixed in frame, is connected with oil cylinder on hydraulic pump, and the other end of oil cylinder and the cantilever of rotary ploughing part are hinged.While carrying out rotary tillage process, control hydraulic pump oil cylinder is regained by the switch on hydraulic pump, at this moment rotovator parts decline and carry out rotary tillage process; After rotary tillage process completes, hydraulic pump control oil cylinder stretches out, and promotes rotary ploughing part and rises, and prevents the concavo-convex part friction in rotary ploughing part and ground.
Advantage and good effect that the invention has are: owing to adopting technique scheme, rotovator is operated convenient; And the cultivated soil original position that all falls back again, has improved production efficiency, and rotary ploughing part is lifted to the drive mechanism falling become hydraulic drive, increased the service life of rotovator, can ensure personal safety well simultaneously.

Embodiment
As shown in Figure 1-2, a kind of rotovator, comprise agricultural transportation vehicle and the rotary ploughing part that hangs on transport vehicle afterbody, rotary ploughing part comprises the rotary ploughing cutter shaft 2 being enclosed within on cantilever 1, agricultural transportation vehicle comprises that head is with the frame 4 of steering wheel 3, in frame 4, be fixed with engine 5 and an arc trailing bar 7, the centre of arc trailing bar 7 has one can, by the hole 21 of rotary ploughing cutter shaft 2 and rotary blade 20, between engine 5 and steering wheel 3, be fixed with driver's seat 9.Rotovator also comprises the hydraulic pump 6 being fixed in frame 4, is connected with oil cylinder 8 on hydraulic pump 6, and the other end of oil cylinder 8 and the cantilever of rotary ploughing part 1 are hinged.
In the invention, the operation principle of rotovator and the operation principle of existing rotovator are consistent, in rotary tillage process, the soil cutting by rotary blade 20, and by soil block throwing backward, just in time clash into mutually with arc trailing bar 7, the further fragmentation of soil block is fallen earthward, played the effect that increases hack and level land.
Above the invention embodiment is had been described in detail, but described content is only the preferred embodiment of the invention, can not be considered to for limiting the practical range of the invention.All equalization variations of doing according to the invention application range and improvement etc., within all should still belonging to the patent covering scope of the invention.
