Background technology
At present, the middle-size and small-size rear ditching machine of sold on the market less than 40 horsepowers, divide two large classes, i.e. dynamic output spindle-type and unpowered output spindle-type, for the rear ditching machine of dynamic output spindle-type, the general earth separation plate that assembles before furrower disc prevents ditched both sides from piling up earth, but due to the easy for installation of consideration and the problem not affecting furrower disc work, earth separation plate generally cannot be pressed close to furrower disc, when earth is dug by furrower disc, part soil can just be scattered in ditched both sides or ditch before contact earth separation plate, the quality of impact trench digging; Blade position simultaneously on existing furrower disc is fixed, and the width of ditching also is fixed thereupon, is unfavorable for the width controlling trench digging; And existing ditching machine is connected mainly through three-point suspension-type with tractor, after connecting, wicking height mainly relies on hydraulic system to drive torque arm effect, and the depth of decline and ditch equally also depends on hydraulic system action, when needs regulate ditching depth, operate very inconvenient.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide a kind of features simple structure, point native better effects if, and trench digging width-adjustable, ditching depth regulates towed rear ditching machine more easily.
The utility model design adopts following scheme for this reason:
Four-wheel tractor ground towed rear ditching machine, comprise frame, one end of described frame is connected with four-wheel tractor, the other end of frame is fixed with speed and direction changing gear-box, the power input shaft of described speed and direction changing gear-box is connected with the power take-off of four-wheel tractor by the band power transmission shaft of universal joint, change gear box Power output axle head be connected with furrower disc, several furrow-opening cutter blades are evenly distributed with along described furrower disc circumferencial direction, frame on front side of described furrower disc is fixed with the earth separation plate that size and furrower disc match, described earth separation plate cross section is V-shaped and have radian to furrower disc curving, frame below described earth separation plate and between furrower disc is also provided with and leads soil box, described soil box of leading is obliquely installed, lead soil box upper end point to earth separation plate bottom and with earth separation plate near, lead the sensing ground, lower end of soil box and adjacent with furrow-opening cutter blade.
Further, side adjacent with furrower disc in described frame is also provided with depth adjusting plate, one end of described depth adjusting plate is flexibly connected with frame by hinge, the middle part of depth adjusting plate is fixed with adjusting bolt, and described adjusting bolt is connected with the limiting plate detachable be connected in frame by nut.
Further, described furrower disc is also provided with at least two group width adjustment cuttves, described width adjustment cutter comprises and being fixed on side by side on furrower disc and contrary two the cutter grooves of opening direction, all be inserted with the bending blade of L-type in cutter groove described arbitrarily, described bending blade tightens in the cutter groove of correspondence by least two screws.
Further, one end of described frame is connected with four-wheel tractor is four-point suspended by two hinge axis and two hangers.
The beneficial effects of the utility model are:
The utility model is set up and is led soil box structure between furrower disc and earth separation plate, adds the contact frequency digging earth and earth separation plate, in the both sides preventing earth to be scattering into trench digging in the process of digging or ditch, ensure that trench digging Quality advance trench digging efficiency; Design depth adjusting plate simultaneously, depth adjusting plate is supported on ground when furrower disc works, one end is connected by hinge can rotates freely with frame, middle part secured adjusted bolt, regulate upper-lower height by nut and then regulate the contact degree of depth of furrow-opening cutter blade and soil, and frame and tractor are connected by four-point suspended, during rise and fall, then only need Manual descending lifting handle can not need to regulate the depth with oil pressure, operate and more easyly also save the energy; Furrower disc in the utility model is also provided with width adjustment cutter, two groups of width adjustment cutter often group by two relatively slidably L-type blades form, regulate distance between two L-type blades by unclamping or compressing corresponding screw, and then width of ditching can be controlled easily.
In sum, the utility model, structure is simple, with low cost, easy accessibility, trench digging quality and efficiency higher, be applicable to the four-wheel tractor of the different types of machines of less than 60 horsepowers dynamic output shafts or exterior dynamic output shaft, suit large area to popularize use.
