Description

Four-wheel machine travel plough

The utility model relates to a kind of agricultural machinery of four-wheel tractor traction, particularly is suitable for the plough of various tractor with small four wheels tractions.

Chinese patent (light reel number GB1508) on June 9th, 1999 was announced the ZL98202911.X patent, its structure comprises frame, preceding plough assembly, back plough assembly and land wheel, be connected with left side, right side and middle three connecting plates in the front lower place of crossbeam, in the horizontal, vertical hole of adjustable plate, a towing pin is housed respectively, three connecting plates are arranged above crossbeam, be articulated in two supporting legs of same lifting support respectively, in the end of left lifting support just cultivated lifter drawing bar is installed, the end of right lifting support is installed with ploughs pull bar partially.This utility model is used different lifting support and towing pin by conversion, can realize just ploughing and ploughing partially.As everyone knows, the tractor with small four wheels of the existing plurality of specifications of China, the power of the every kind of type especially span of two driving wheels is different, three of this utility model traction connecting plates and the position of lifting support connecting plate on crossbeam are fixed, 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, when using right lifting support to carry out inclined to one side farming industry, left lifting support will hinder the left driving wheel operate as normal.

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

For achieving the above object, the technical scheme that the utility model is taked is: middle part and rear portion at plow frame are respectively equipped with land wheel and ploughshare assembly, the front end of plow frame is a crossbeam, crossbeam is provided with two groups of totally four otic placodes, the suspension holdfast lower end connects with wherein one group of otic placode, strut one end and suspension holdfast are hinged, the other end is provided with two pin-and-holes, wherein one with the bearing pin pin joint that is located on the plow frame, also be provided with two blocks of fixed traction plates on the crossbeam, crossbeam also is provided with horizontal clamping plate up and down between two blocks of fixed traction plates, horizontal up and down clamping plate are provided with the pin-and-hole of arranging about a group, adjustable towing plate end is provided with axle sleeve and is connected in up and down in the pin-and-hole between horizontal clamping plate the pin-and-hole of arranging before and after fixed traction plate and adjustable towing plate respectively are provided with a group by pin.

By above scheme as seen, the utility model only is provided with one pair of suspension holdfast, and changing three otic placodes is four otic placodes, and it can be changed with connecting of two groups of otic placodes according to the operation needs and realize just ploughing or ploughing partially, not only solve the problem that hinders left driving wheel when ploughing partially, also made inclined to one side working width wide increasing; Left side fixed traction plate cooperates with adjustable towing plate, can realize just cultivated, right fixed traction plate cooperates with adjustable towing plate, can realize ploughing partially, since adjustable towing plate can with horizontal clamping plate on about one group arrange any pin joint of pin-and-hole, the lateral separation between the operation towing plate can be regulated, when plough is cooperated with the tractor with small four wheels of different driving wheel span, the soil that driving wheel rolled can both be ploughed; The pin-and-hole of arranging before and after all not having one group on each towing plate can obtain just ploughing or cultivated partially scheme of different working widths by the multiple combination of towing pin and the cooperation of different pin-and-holes.

Accompanying drawing 1 is the structural representation of the utility model embodiment;

Accompanying drawing 2 is structure charts of adjustable towing plate.

Now reaching accompanying drawing in conjunction with the embodiments is described further.The present embodiment scheme is referring to accompanying drawing 1, frame by about two longerons 1 and 14, a cant beam 15 and a crossbeam 10 combine, ground wheel assembly 13 is fixed on left longeron middle part, back plough assembly 16 is fixed on the rear end of left longeron, preceding plough assembly 12 is fixed on the rear end of right beam, cant beam is provided with pin 2, strut 4 one ends are fixed on the cant beam by pin 2, hole 3 is in order to regulate the length of strut, the strut other end and suspension holdfast 5 are hinged, be illustrated as the state of just ploughing, suspension holdfast 5 is fixed on the one group of otic placode 6 in crossbeam 10 left sides, the crossbeam two ends are fixed with left and right sides towing plate 7 and 11, have two holes that cooperate with towing pin on the every towing plate, the middle part of crossbeam is welded with joins the horizontal up and down clamping plate 8 that bore three groups of holes, adjustable towing plate 9 is by riser 9a, transverse slat 9b and a steel pipe (axle sleeve) 9c assembly welding form, as shown in Figure 2, have on the riser three only with lead the hole that pin cooperates, transverse slat end face S contacts with horizontal clamping plate groove bottom up and down and is used to prevent that adjustable towing plate from rotating around the steel pipe axis, latch passes train wheel bridge successively, steel pipe and lower plate can be fixed adjustable towing plate, can adjust the position of adjustable towing plate different pin-and-holes in horizontal clamping plate up and down for the tractor with small four wheels of different driving wheelspan, realize removing driving wheel and roll the cultivated partially of soil.

Claims (1)
