Description

The hand machine tracting side hanging plow

The utility model relates to a kind of agricultural machinery of hand tractor traction, particularly is suitable for the plough of various hand tractor tractions.

Chinese patent (light reel number GB1516) on November 17th, 1999 was announced the ZL98222166.5 patent, its structure comprises two plow beams and is hinged on the hanger bracket and the plough Connection Block of plow beam front and back end, the hook type plow frame is hinged on the plow frame Connection Block, its lower end is fixed with sleeve pipe, be contained in the front end fixed installation plough shovel of the rotating shaft in the sleeve pipe, the rear end is hinged with the angular adjustment handle, plough mouldboard is movably arranged on the plow frame bottom by hinge, its lower end contacts with the plough shovel is movable, also is separately installed with cultivated partially adjusting device and depth adjustment in plow beam front portion and plow frame top.Plough adjusting device partially by being welded on fan-shaped fluted disc on the hanger bracket, being fixed on the adjusting rod bearing on the plow beam and the adjusting rod that is hinged on the bearing constitutes, this utility model, can realize just ploughing and cultivated partially in the different teeth of fluted disc position by the conversion adjusting rod.As everyone knows, the hand tractor of the existing plurality of specifications of China, the power of the every kind of type especially span of two driving wheels is different, the fluted disc of this utility model is fixing nonadjustable, thereby only be fit to the tractor of a certain specific standard, during with the tractor of other driving wheel span diverse, because its fixing restriction of the value of ploughing partially can't be carried out farming to the soil that driving wheel rolled; Secondly, the fault that adjusting rod is jumped out from the fluted disc tooth easily takes place.

The purpose of this utility model is that a kind of can ploughing partially with walking tractor matching use, the realization of various driving wheel distances of design measured adjustable trailer plough.

For achieving the above object, the technical scheme that the utility model is taked is: adopt two parallel plow beams with before, rear connecting frame is hinged to a quadric chain, preceding link front end is fixed with traction tube and left and right sides jackscrew, the rear connecting frame rear end is fixed with two straps, the plough assembly is housed on the strap, the rear connecting frame upper surface is fixed with a circular arc adjustable plate, there is a locating hole in the adjustable plate center of circle, be on the arc in the center of circle one group of fine setting hole and one group of adjustment hole to be arranged with the locating hole, left side plow beam is provided with an otic placode, otic placode is hinged with adjusting pin middle part, and regulating pin top is handle, and the bottom is the pin head that cooperates with adjustment hole.

By above scheme as seen, when the utility model adopts locating hole and a fine setting hole secured adjusted plate, the hand tractor that can adapt to a kind of driving wheel distance, when adopting locating hole and another fine setting hole secured adjusted plate, the hand tractor that then can adapt to another driving wheel distance, that is to say, hand tractor for a certain specific model, can use locating hole and a certain fine setting hole to fix adjustable plate, can make according to the needs of just ploughing or ploughing partially then and regulate a certain adjustment hole of pin insertion, just can guarantee to realize to have ploughed when ploughing partially the soil that driving wheel rolled.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the adjustable plate structure chart.

Now reaching accompanying drawing in conjunction with the embodiments is described further.The present embodiment scheme is referring to Fig. 1, left and right two plow beams 7,8 and front and back link 4,5 pin joints constitute a quadric chain, before be rotary with on the link 4 about two jackscrews 2,1 and be welded with a traction tube 3, two clamping plate 17 of rear connecting frame 5 welding, plough bow 19 middle parts are hinged in the clamping plate 17 by bolt 18, plough bow 19 upper ends connect with the depth adjusting device that seat board 15, screw mandrel 14 and handle 16 constitute, and ploughshare 20, plough point 21, side plate 22 and supporting plate 23 are equipped with in plough bow 19 lower ends.Referring to Fig. 2, adjustable plate 11 is an arc plate, and fixing hole 26 is located at the center of circle, and it is being on the circular arc in the center of circle with fixing hole 26 that three fine setting holes 24 and six adjustment holes 25 are opened.Two pins 12 on the rear connecting frame 5,13 pass fixing hole 26 and the fine setting hole 24 on the adjustable plate 11, with adjustable plate 11, rear connecting frame 5 and two plow beams 7,8 connect, the otic placode 9 that is fixed on the left plow beam 7 is hinged with adjusting pin 10, mention adjusting pin 10 and make plow beam 7,8 around pin 12, during 13 rotations, each adjustment hole 25 all can arrive regulates pin 10 pin head belows, inserting adjusting down at a certain adjustment hole 25 sold 10 o'clock, left and right sides plow beam 7,8, front and back plow frame 4,5 quadric chains that constitute are by locked, if what this moment, pin 13 was worn is another fine setting hole 24, the angle of quadric chain deflection is obviously different, can adapt to the hand tractor of different driving wheelspan.
