Abstract

The utility model provides an agricultural tillage machine which mainly comprises a machine frame, a diesel engine arranged on the machine frame, a speed reducer, a walking wheel train and a plough body. The agricultural tillage machine is characterized in that the plough body is composed of a fixed type plough wall and a movable type plough share. The diesel engine drives a vibrator through a belt transmission mechanism, the vibrator transmits exciting force to the movable type plough share through a vibrating arm and the plough share can generate strong impact force to be cut into the soil. The diesel engine drives a gear disc type walking wheel simultaneously through an automatic speed regulating device, a speed reducing device, a belt and a chain transmission mechanism to generate the adhesive traction force so as to make a machine body and the plough body forwards moved and the soil which is cut by the plough share immediately enters the plough wall and is broken and rotated. The agricultural tillage machine has the advantages of simple structure, light weight, sufficient utilization of motive power and high tillage efficiency and is suitable for the plowing of various dry lands.

Description

Osccilant share formula mini-size tillage machine

The utility model relates to a kind of agricultural machinery, particularly a kind of small-sized ploughing machine of the usefulness of ploughing.

Existing a kind of miniature ploughing machine mainly is made of frame, rack-mounted diesel engine, speed changer, walking train and transmission mechanism thereof and the fixed plough body that is arranged on the frame front end.Utilize diesel engine the power drive ploughing machine the walking train and drive the shear strength incision soil that plough body (being made of parts such as ploughshare and mouldboards) overcomes soil, realize ploughing to soil.The shortcoming of this equipment is that requirement road wheel cording is equipped with the bigger tractive force that adheres to, and often causes the deadweight of equipment excessive, handles and carrying is very difficult, power consumption is big, ploughing capacity is not high.

The purpose of this utility model is that existing mini-size tillage machine is improved, and provides a kind of from heavy and light, power consumption is little, ploughing capacity is high osccilant share formula mini-size tillage machine.

The formation of osccilant share formula mini-size tillage machine of the present utility model comprises frame, rack-mounted diesel engine, decelerator, front and back walking train and its transmission mechanism and is arranged on the plough body of frame front end.Described plough body is made of a fixed mouldboard and an oscillatory type ploughshare.The oscillatory type ploughshare connects a vibrator by a shaker arm, is provided with a stage clip between shaker arm and frame sliding sleeve, and vibrator joins by a belt gear and diesel engine.

The course of work of this vibration ploughshare mini-size tillage machine is as follows: the power part from diesel engine drives the fuselage walking by the decelerator ground-engaging wheel, a part passes to vibrator, make vibrator produce dither, the exciting force that vibrator produces passes to movable ploughshare, make the ploughshare unidirectional powerful impulsive force of generation and cut soil, the soil that is cut by ploughshare enters mouldboard again and is broken, overturns, realize to soil dig, hack plough purpose.

The utility model puts on movable ploughshare with power by the exciting force that vibrator produces, and has improved the shearing function of ploughshare for soil greatly, makes power be able to fully, effectively utilize.After soil is cut by ploughshare, enter in time that mouldboard is reversed, fragmentation, and in this case, for car resistance and little.So, can reduce to plough the requirement of adhering to tractive force for the walking train, that is: the effective weight that can reduce fuselage.Help frequent carrying between the fritter field and operation, use.

The utility model is described in further detail below in conjunction with drawings and Examples.

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

Fig. 2 overlooks the shape structural representation

Fig. 3 is the structural representation of vibrator

Shown in Fig. 1～3, diesel engine 17, decelerator 13, front walking wheel 4, rear walking wheel 9 are installed on the frame 10, are provided with two

belt pulleys

14 and 15 on the output shaft of diesel engine, drive train transmission mechanism and vibrating mechanism respectively.Wherein, belt pulley 14 is selected stepless speed regulation formula belt pulley for use, joins by the power shaft belt pulley 12 of belt 30 with decelerator 13, and when the train running resistance was big, the working diameter of belt pulley 14 was dwindled automatically and slowed down; Otherwise working diameter increases and speedup automatically, realizes automatic speed regulation.The output shaft of decelerator is provided with a minor sprocket 11, drives the hinge wheel above the wheel shaft that is installed on rear walking wheel 9 by chain 31, thereby realizes travelling of road wheel.The wheel disc periphery of rear walking wheel 9 can be provided with some tooth plates 33, make it in the process of walking that tooth plate is absorbed in the soil, increasing the coefficient of friction between wheel disc and the last earth, thereby make gear mechanism under the driving of diesel engine, produce the bigger tractive force that adheres to, be beneficial to that fuselage is stable to move ahead.

Plough body is made up of the movable ploughshare two parts that are fixed on the fixed mouldboard on the frame 10 and be fixed on the shaker arm 20.Shaker arm is installed in the frame sliding sleeve 3, and hinged with vibrator 5 usefulness pins 28.Stage clip 21 is socketed on the shaker arm 20, and the front end apical grafting is on the boss 38 of shaker arm, and the rear end apical grafting is on frame sliding sleeve 3.The other end of vibrator can be connected with frame by an outer support bar 27 that is with stage clip 26.Referring to Fig. 3: the formation of vibrator comprises that mainly two vertically arranged axles of symmetries are parts, respectively carries 24,35, one gears 23,36 of an eccentric hammer.Wherein driving shaft 37 1 ends are installed belt pulley 6.The power of diesel engine is then by passing to driving shaft 37 by belt pulley 15,7,6 transmission mechanisms of being formed, and by gear drive two eccentric hammer rotated in opposite directions.In vertical direction, because the quality of two eccentric hammer and rotating speed equate that the moment of inertia of Chan Shenging equates respectively, what produced just in time cancels out each other with joint efforts, does not produce the vibration of vertical direction; In the horizontal direction and with the vertical symmetrical line is the boundary, when two eccentric hammer turn to the left side or the right simultaneously, then makes vibrator produce the vibration of horizontal direction.Thereby make movable ploughshare produce the vibration of horizontal direction by shaker arm.Because the effect of stage clip 21, when direction of vibration was the right, stage clip was compressed, and buffering is also stored the kinetic energy that produces owing to direction of vibration; When direction of vibration was the left side (direction of ploughshare incision soil), vibrator drive shaker arm and ploughshare were to left movement, and simultaneously, stage clip unclamps and discharge kinetic energy.Thus, the exciting force that vibrator produces almost all passes to ploughshare, produces strong wallop, makes ploughshare incision soil, makes soil enter the mouldboard part.Under the driving of rear walking wheel 9, mouldboard carries out constantly broken and upset with soil, thereby finishes ploughing soil.Operation handrail 29 is installed on frame.

At the frame front end, the connecting rod 16 that installation can be done to move both vertically, the semiaxis of connecting rod lower end is installed front walking wheel 4, the operating mechanism that adjusting is made up of lever 19 and operation pull bar 18, can make the ploughshare on the frame is fulcrum with the rear walking wheel bottom, do swinging up and down of vertical direction with respect to front walking wheel, regulate the tilling depth thickness of ploughshare incision soil thus.
