Abstract

An agricultural caterpillar-type ditching machine comprises a caterpillar-type tractor and a ditching device mounted at the back of the tractor, wherein a reducer has three output shafts, a left output shaft and a right output shaft are meshed with a left caterpillar drive gear and a right caterpillar drive gear through gears, the third extended output shaft of the reducer is meshed with a driven belt pulley in the middle of a square spindle on the ditching device through a driving pulley at a shaft end, the square spindle is mounted at the lower end of a supporting rod at the lower part of a rack through a bearing pedestal, the front end of the rack is connected with the rear of the tractor through pin holes, and 2-3 openers are mounted on the square spindle; a diesel enables cutter heads to rotate through the square spindle, arc-shaped coulters cut earth forward, rear ditch cleaning moldboards lift earth to two sides of each ditch, 2-3 ditches can be opened simultaneously, and intervals between the ditches and the depths of the ditches can be adjusted. The agricultural caterpillar-type ditching machine is high in working efficiency and is suitable for soil conditions in the Dongting Lake District and the Poyang Lake District.

Description

Agricultural crawler type ditching machine

Technical field

The utility model relates to farm machinery, i.e. a kind of agricultural crawler type ditching machine.

Background technology

Lake Dongting area and Poyang Lake District, farmland underground water level is higher, the draining of often need to ditching, mostly use now wheel tractor traction ditching device to ditch, employing wheel tractor is used as power, it has individual shortcoming, be exactly that wheel is easily absorbed in mud and skids, cause wheel tractor tractive force deficiency, if the wheel tractor that adapted is excessive, cause again waste, in ditching device, useful fan-shaped blade rotation, excavate many ditches simultaneously, in CN202697165U patent, this device is only applicable to northern sandy soil ground, to southern red soil, by blade, rotation is dug motionless, for stronger soil, have the rotation of plow-shape blade is installed on cutterhead, a ditch of excavation, in CN203057819U patent, if used in lake region, once only dig Yi Tiaogou, this unit efficiency is too low, the ditching machine that develops a kind of applicable lake region hydrogeologic condition is lake region peasant hope for many years.

Summary of the invention

Easily be absorbed in mud for fear of wheeled ditcher, and the inefficient shortcoming of plough formula ditching machine, the utility model proposes a kind of new design of agricultural crawler type ditching machine.

This agricultural crawler type ditching machine, comprise caterpillar tractor and be arranged on tractor ditching device below, on the chassis of tractor, diesel engine is installed, diesel engine passes through belt, belt pulley is connected with reductor, it is characterized in that, reductor has three output shafts, left output shaft, right output shaft is by gear and left track drive gear, right-hand track chiain driven wheel is meshed, the 3rd output shaft stretching out of reductor, negative pulley wheel by the square main shaft middle part on drive pulley and the ditching device of axle head is meshed, square main shaft is arranged on the lower end of the support bar of the bottom of frame by bearing block, the front end of frame is connected with tractor rear portion by pin-and-hole, depth adjustment bar is arranged at the bottom at two ends, frame left and right, there is support skid the lower end of depth adjustment bar, two ploughs are installed on square main shaft.

Plough comprises a cutterhead, there is a square hole matching with square main shaft at cutterhead center, cutterhead is arranged on square main shaft, cutterhead both sides are fixed the position, left and right of cutterhead by the pin-and-hole on square main shaft, the outer of cutterhead is provided with several curved blades uniformly, the ditch cleaning moldboard that arc is installed at the rear portion of cutterhead, the upper end of ditch cleaning moldboard is fixed on support bar.

When work, diesel engine drives tractor to move ahead by left and right crawler driving whell on the one hand, diesel engine makes cutterhead rotation by square main shaft simultaneously, curved blades is cut the earth forward, and ditch cleaning moldboard below lifts soil on the both sides of ditch, can open 2-3 bar ditch simultaneously, the spacing of ditch can regulate by the pin-and-hole of cutterhead both sides, the degree of depth of ditch can regulate by the depth adjustment bar of bottom, square main shaft two ends, and the utility model operating efficiency is high, is applicable to the soil condition of Lake Dongting area and Poyang Lake District.
