Abstract

The utility model discloses a rotavator which comprises rake cutter wheel frames, a power walking machine and a chain wheel mechanism, wherein the rake cutter wheel frames are arranged at both sides of a rake cutter wheel and are used for mounting the rake cutter wheel; the chain wheel mechanism is used for conveying power to the rake cutter wheel; the rake cutter wheel frames are movably articulated on a driving chain wheel shaft frame of the chain wheel mechanism; and a reinforcing plate is connected between the rake cutter wheel frames at both sides of the rake cutter wheel. Compared with the prior art, the utility model can solve the problem that the prior rotavator can only adjust the in-soil depth by stopping working in an operation process.

Description

Rotovator

Technical field

The utility model relates to the farm implements technical field, especially a kind of rotovator.

Background technology

Existing rotovator; it includes the power walking machine and is positioned at the support that rake break bar axle both sides are used to install the rake break bar; the rotovator of this structure; its rake break bar support is to be contained in regularly on the axle bracket of drive sprocket; and the drive sprocket axle bracket is to be fixedly attached on the frame of power walking machine; after rake break bar axle is loaded onto support; the touchdown point of three wheels of rake cutter and main frame is at grade basically; during farm work; the tail wheel frame is reduced; the complete machine layback drives the rake cutter and goes into ground; there is following problem in it in operation process: 1; the rake cutter is gone into the depth on ground and can only be regulated by regulating tail wheel frame height; and need shut down adjusting when regulating, and can not regulate on operation limit, limit, so inefficiency.2, it is limited to utilize the tail wheel frame to regulate the depth.Because the rake cutter spacing is between the driven wheel and tail wheel of power walking machine, when tail wheel being dropped to minimum the time, the rake cutter is gone under the also unfavorable situation of the degree of depth on ground, just can't regulate, and much users can only bleed off half to the gas of driven wheel after helpless.3, when the tail wheel frame descends, be positioned at the power walking machine driver's seat of tail wheel frame top and the distance of tail wheel and change thereupon, the driver is not easy to grasp the direction of tail wheel.4, when rotovator enters paddy-field-working, the driven wheel of power walking machine and tail wheel sink, and the rake cutter also can sink thereupon, and when falling into too deeply, the load of power walking machine is too big, and can cause can't operation.5, entering farm work, when soil property was harder, rake cutter self can not be from main regulation, thereby upsprings, and makes tail wheel unsettled, and the rake cutter becomes the driven wheel walking, damages easily.

Summary of the invention

Rotovator provided by the utility model can solve existing rotovator and must shut down the problem that could regulate the depth of burying in operation process.

In order to address the above problem, the scheme that the utility model adopts is: include to be positioned at and harrow the rake break bar support that the break bar both sides are used to install the rake break bar, power walking machine and the chain-wheel mechanism that is used for transmitting power to the rake break bar, described rake break bar support is to be hinged on versatilely on the drive sprocket bracing strut of described chain-wheel mechanism, is being connected with stiffener between the rake break bar support of rake break bar both sides.

In such scheme, on described power walking machine, can be provided with movable hinge, the rake cutter elevating lever of lever construction is installed on this hinge, being connected on the described stiffener of an end activity of this rake cutter elevating lever, the other end extends the driver's seat of main frame.

Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:

1, rake break bar support and the activity of drive sprocket bracing strut is hinged, and therefore, when rotovator entered farm work, rake break bar support can be according to the soft or hard degree of soil property, and around the weight that pin joint buries from main regulation, cutter is harrowed in protection.

2, at the rake cutter elevating lever that on the stiffener of rake break bar support, connects lever construction, therefore, the driver is in operation process, can be as required, directly control rake cutter elevating lever is regulated the height of harrowing knife rest on the seat, realize the purpose that operation limit, limit is regulated, thereby increase work efficiency and work quality.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the power transmission structure schematic diagram of harrowing among Fig. 1 between break bar and the walking machine.

Embodiment

Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:

Fig. 1, rotovator shown in Figure 2, it includes the power walking machine 8 of hand tractor structure, the power take-off of power walking machine 8 sends power to the drive sprocket axle that is contained on the drive sprocket bracing strut 2 by gear-box 3, the drive sprocket 9 that is contained in drive sprocket axle one end sends power the driven sprocket 11 of wheel shaft one end that is contained in rake break bar 4 to by chain 10, thereby drives 4 rotations of rake break bar.The two ends of rake break bar 4 are contained on the rake break bar support 1, and rake break bar support 1 is again to be hinged on versatilely on the drive sprocket bracing strut 2.Between the rake break bar support 1 at rake break bar 4 two ends, be connected with stiffener 7.On the frame of power walking machine 8, be provided with movable hinge 12, the rake cutter elevating lever 6 of lever construction is installed on hinge 12, one end of this root rake cutter elevating lever 6 is movable being connected on the stiffener 7, the other end extends the driver's seat 5 of power walking machine, also is provided with the positioner of rake cutter elevating lever 6 on the frame of power walking machine 8.The driver can be as required in operation process, and control rake cutter elevating lever 6 is regulated the height of rake break bar on driver's seat 5.

Claims

[claim 1] a kind of rotovator, include and be positioned at the rake break bar support that rake break bar both sides are used to install the rake break bar, power walking machine and the chain-wheel mechanism that is used for transmitting power to the rake break bar, it is characterized in that: described rake break bar support is to be hinged on versatilely on the drive sprocket bracing strut of described chain-wheel mechanism, is being connected with stiffener between the rake break bar support of rake break bar both sides.
