Description

The automatic regulating type mini-size tillage machine of a kind of tilling depth
Technical field
The utility model relates to a kind of mini-size tillage machine.
Background technology
China is a large agricultural country, and scale of agricultural operation is main with family, and hills and mountain area account for very large tracts of land, and the plot is little, and is uneven, the suitable large-scale agricultural machinery of a usefulness.In the case, promoting mini-size tillage machine is the important means that realizes the mechanization of farm work.
Mini-size tillage machine is a power with miniature gasoline engine or diesel engine, has characteristics such as light weight, volume be little, simple in structure, adaptable across the Plain, mountain area, nonirrigated farmland, hills, paddy field, orchard etc.But mini-size tillage machine in use, many problems also occurred: (1) work is not steady.Adaptability to soil during the mini-size tillage machine operation is relatively poor, and fuselage shaking is bigger.(2) tilling depth is unstable.During the mini-size tillage machine operation, field piece dipping and heaving out-of-flatness, especially field, mountain and hill area piece, along with the continuous variation of soil regime, the also continuous dipping and heaving of tilling depth adjusting rod causes tilling depth extremely unstable.
In use, in order to solve above-mentioned two problems, traditional mini-size tillage machine requires operating personnel to carry the pressure handrail constantly off, labor intensity of operating personnel is required high, if the long-time mini-size tillage machine that uses, the long bubble of palm, callous, the phenomenon of casting off a skin is very outstanding.And the present most of rural areas of China are: person between twenty and fifty go out to work, women, children, the stay-at-home rural area of old man.Tradition mini-size tillage machine " liberated ox, the people is dead tired " has to again simultaneously in the face of the present situation of a large amount of losses of labour, caused one of major reason of China's mini-size tillage machine in recent years " push away and wideless ".
The utility model content
The purpose of the utility model is to provide a kind of automatic regulating type mini-size tillage machine of tilling depth that can regulate tilling depth automatically.
To achieve these goals, adopt following technical scheme: the automatic regulating type mini-size tillage machine of a kind of tilling depth comprises support and the rotary blade that links to each other with support; It is characterized in that: said support is provided with the tilling depth adjusting device, and the tilling depth adjusting device comprises the installing plate that is connected on the support, is fixed with the feed screw nut on the installing plate; Screw mandrel passes the feed screw nut and is connected with adjusting rod, and screw mandrel links to each other with the output shaft of motor, and the shell of motor links to each other with guide rail on being fixed on installing plate; Mini-size tillage machine is provided with the tilling depth checkout gear; According to the output signal of tilling depth checkout gear, controller control motor positive and inverse drives the screw mandrel rotation; Make motor on guide rail, move, drive the motion of adjusting rod simultaneously.
Said tilling depth adjusting device is arranged at the place ahead or the rear of rotary blade.
Said adjusting rod is the helical form adjusting rod.
The utility model detects the direction of rotation drive screw mandrel motion that the rotary tillage degree of depth is controlled motor in real time through the tilling depth checkout gear; Thereby helical form tilling depth adjusting rod is moved up and down; Realize the automatic adjusting of tilling depth, increase work efficiency, alleviate labor intensity of operating personnel.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
Fig. 3 is an adjusting rod structural representation in the utility model;
Fig. 4 is the cutaway view of A-A among Fig. 1 and Fig. 2.
In the accompanying drawing: 1 is that handrail, 2 is that motor, 3 is that guide rail, 4 is that installing plate, 5 is that feed screw nut, 6 is that screw mandrel, 7 is that adjusting rod, 8 is that engine, 9 is that generator, 10 is that support, 11 is a rotary blade.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be further described.
Embodiment 1: extremely shown in Figure 3 like Fig. 1; The automatic regulating type mini-size tillage machine of a kind of tilling depth; Support 10 is provided with the tilling depth adjusting device, and the tilling depth adjusting device comprises the feed screw nut 5 and screw mandrel 6 who is fixed on the installing plate 4, and adjusting rod 7 is connected with screw mandrel 6; Screw mandrel 6 is connected with motor 2, and motor 2 is arranged on the guide rail 3 that is connected with installing plate 4.Mini-size tillage machine is provided with the tilling depth checkout gear, according to the output signal of tilling depth checkout gear, moves up and down and regulates thereby make screw mandrel 6 motions drive adjusting rod 7 then through controller control motor 2.The tilling depth checkout gear normally is arranged on the checkout gear that can detect the mini-size tillage machine tilth on the rotary blade coaxial direction,
The relative rotary ploughing cutter shaft of mini-size tillage machine center of gravity will be satisfied a little backward in the position of rotary ploughing cutter shaft; Be to move after the center of gravity, the tilling depth adjusting device is installed in the rear end of engine 8, under action of gravity; Adjusting rod 7 inserts soil, makes that the rotary blade 11 rotary tillage degree of depth are relevant with the insertion depth of adjusting rod 7.
During operation, in most of the cases operating personnel only need hold up handrail 1 and control throttle and turn to, and stablize tilling depth and are then accomplished by controller.When tilling depth is more shallow, 2 counter-rotatings of controller control motor, it is descending to make screw mandrel 6 motions drive adjusting rods 7, and under mini-size tillage machine gravity, the adjusting rod 7 dark soil of inserting increase car resistance, prolong rotary blade 11 and revolve and hit the soil time, increase the real-time rotary tillage degree of depth.On the contrary, when tilling depth was dark, controller control motor 2 was just changeing, and screw mandrel 6 was moved upward drive adjusting rod 7 up relatively, and car resistance reduces, and shortens to revolve the time of hitting, and reduces the rotary tillage degree of depth.
Embodiment 2: as shown in Figure 2, different with embodiment 1 is, the relative rotary ploughing cutter shaft of mini-size tillage machine center of gravity a little forward, i.e. center of gravity reach, simultaneously, the tilling depth adjusting device is installed in the front end of engine.
