Description

The soil harvesting and tillage machine

The utility model relates to small-sized arable land, scarification equipment.

The small-sized harvesting and tillage machine of prior art mainly is to be dynamic power machine with hand tractor or little four-wheel, trailer plough, rake, facility such as sower carry out operation, and the mechanical weak point of above-mentioned form is that machine needs tractor road when entering the field, otherwise, can't enter the field, farm work that also just it doesn't matter.

For addressing the above problem, Chinese patent 921082983 discloses a kind of mini-size tillage machine, and it is by ploughing zinc, power set, operating mechanism, running gear, primary structures such as frame formation.Main feature is to adopt the mono-track walking, adopts triangular structure on machine is arranged, can improve trafficability characteristic on the trail, mountain area, walk on the ridge.The weak point that exists is because of having adopted the mono-track walking, and vibratility is very big when operation, and general personnel can only work 10-20 minute, again can't operate, and labour intensity is too big; Another weak point is to regulate the ploughshare embedded depth at any time, when the soil not at ordinary times, it is shallow deeply suddenly that the ploughshare embedded depth is neglected, ploughshare passes through on the ground sometimes.The above-mentioned weak point that produces because of reasons in structure, to making in investment-saving such as Sichuan more than 100,000,000 yuan, the research of tens of families, the technology of assigning also can't come into operation so far, cause heavy losses.

Of the present utility model is at above-mentioned weak point, provides vibratility little, can adjust the ploughshare embedded depth at any time according to state of ground, the small-sized soil harvesting and tillage machine of smooth running.

The utility model is that the utilization activity connects the reduction shaking force and keeps the Power Drive Unit normal pressure, utilize lever principle, improve yarage, concrete technical scheme is with Power Drive Unit and control frame is movable connects, and control frame connects with the ploughshare activity, connect by activity, reduced triangular influencing each other, the control frame front end is the force with the ploughshare, and the rear end is the force with the handle, the moment of rear end is greater than front end, thereby improved yarage; For keeping the machine balance, be provided with bascule in the control frame both sides, road wheel is provided with the pointed cone tooth.

The drawing explanation.

Fig. 2 is Figure 1A-A profile;

Fig. 3 is Figure 1B-B profile;

Fig. 4 is Fig. 1 C-C profile;

Fig. 5 is Fig. 1 D-D view;

Fig. 6 is the adjuster schematic diagram of regulating about ploughshare.(Fig. 2 to Fig. 6 has amplification than the ratio of Fig. 1)

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment).

With reference to shown in Figure 1, the power driving device comprises diesel engine 1, belt 2, speed change clutch 3, road wheel 14, frame 11; Diesel engine 1 is given speed change clutch 3 through belt 2 with transmission of power, behind clutch speed-changing, passes in road wheel 14 by belt 23, thereby drives the entire machine walking.Diesel engine 1, speed change clutch 3 is contained in frame 11 back upper places, also can be contained in road wheel 14 front upper places, because of being small-sized machine, guaranteeing operating flexibility and not increasing under the prerequisite of vibrations, should increase the normal pressure to road wheel 14 as far as possible.

With reference to Fig. 1, shown in Figure 2, ploughshare 17 is located at the machine front end, and a rotating shaft 18 is arranged on the ploughshare 17, control frame 7 front ends have an axis hole and rotating shaft 18 to match, and rotating shaft 18 is contained in the axis hole, but rotating shaft 18 left-right rotation, but thereby make ploughshare 17 with rotating shaft 18 left-right rotation, control frame 7 and 17 movable connections of ploughshare.Frame 11 and control frame 16 movable connections of 7 usefulness hinges, when control frame 7 when hinge 16 rotates, drive ploughshare 17 and also rotate around hinge 16, thus adjustment ploughshare 17 embedded depths.With the movable frames 11 that connect of hinge 16, can make the shaking force that transmits by frame 11 alleviate vibrations to control frame 7 and ploughshare 17.Connector is except that hinge 16, and also available multi-directional ball connects, cross axle connection etc.Control frame 7 can be arranged on machine top or both sides behind machine, also can change control frame 7 into tower structure.

With reference to Fig. 1, shown in Figure 3, road wheel 14 is located between the frame 11, road wheel 14 is made of two wheels, hand hay cutter is close together in the two-wheeled, the edge of relaxing outward is provided with the gear teeth, is sharp cone distal, with the adhesive force of increase with the soil, be provided with belt grooves in the middle of the road wheel 14, match with belt 23, belt 23 is given road wheel 14 with transmission of power, and road wheel 14 drives the machines operation of advancing, frame 11 and road wheel 14 usefulness central shafts 15 connect, central shaft 15 both sides are provided with screw thread, are used to connect other facility, as rotovator, rake, sower.With key fixed center axis 15 and road wheel 14, control frame 7 is process in the middle of road wheel 14.

With reference to Fig. 1, shown in Figure 4, on control frame 7, be provided with support plate 13, support plate 13 is provided with 4 locating holes 12, is provided with a locating hole on frame 11, when frame 11 when hole on the support plate 13 overlaps, insert lock shaft 19, just that frame 11 is highly fixing.Lock shaft 19 is in independent walking, and rake uses during rotary tillage, need not when plowing.

With reference to Fig. 1, shown in Figure 5, be provided with bascule in control frame 7 both sides, bascule is made of balance plate 10 and adjuster 9, balance plate 10 and 9 movable connections of adjuster, adjuster 9 usefulness crossbeams 20 are fixed on the control frame 7, and adjuster 9 is by cross coupling spindle, control lever, locating slot, joystick constitutes, and when pulling control lever handle up or down the time, balance plate 10 moves with control lever, raise or reduction, balance plate 10 can be fixed at various height.When plough during the level land, two balance plates, 10 height should be basic identical (one side or not plough low slightly), when the plough hillside fields, should two balance plates 10 be transferred to different height with the slope change in hillside fields.Be provided with handle 6 in the rear end of control frame 7, when plowing, raise or force down handle 6, just can adjust ploughshare 17 embedded depths.

With reference to Fig. 1, shown in Figure 6, be used to regulate the adjuster 8 of ploughshare about 17, front end links to each other with ploughshare 17, and the casing 21 of adjuster 8 is fixed on the control frame 7, and adjuster 8 is by adjusting rod, casing 21, spring constitutes, and spring is contained in the casing 21, and an end touches mutually with casing 21, the other end touches mutually with adjusting rod, and adjusting rod may be stuck on the casing 21.When adjusting ploughshare 17 left and right sides angles, push away adjusting rod forward, ploughshare 17 pulls back to the right, and ploughshare 17 is left.
