Abstract

A caterpillar tractor with a suspended farm tool frame comprises a power walking part and the suspended farm tool frame. The power walking part and the suspended farm tool frame are connected in a front-and-back mode. The upper portion of the suspended farm tool frame is provided with a farm tool gearbox. An upper supporting rod is mounted on the upper portion of the farm tool gearbox through a pin hole. The other end of the upper supporting rod is connected with a machine frame through a pin hole. A hydraulic oil cylinder is mounted in the middle of the upper supporting rod through a pin hole. The other end of the hydraulic oil cylinder is connected with the machine frame through a pin hole. A left lower supporting rod and a right lower supporting rod are mounted on the lower portion of a gearbox II through pin holes. The other end of each lower supporting rod is connected with a farm tool cover through a pin hole. Farm tool mounting plates are arranged at two ends of the farm tool cover. By means of stretching or shortening the hydraulic oil cylinder, the upper supporting rod can be pulled to rise or drop, and the lower supporting rods and the suspended farm tool frame can be made to rise or drop, so that the depth of cultivation through a farm tool is adjusted. In addition, various farm tools such as a cattail roll, a rake and a rotary tillage roll can be mounted in the suspended farm tool frame, the whole caterpillar tractor is dragged by a caterpillar track, and therefore the caterpillar tractor walks stably and is suitable for all kinds of landforms.

Description

A kind of crawler tractor that hangs the farm implements frame that has

Technical field

The utility model relates to farm machinery, i.e. a kind of crawler tractor that hangs the farm implements frame that has.

Background technology

Present farm machinery is wheeled driving mostly, and just walking is unstable to run into irregular landform; Even overturn and to cause the accident, the farm machinery of wheeled driving jolts terribly, and operating personnel are very arduous, on the other hand, the kind of farm implements is a lot, and the peasant wishes the multiple farm implements of a kind of farm machinery energy traction, is pretty troublesome things but change farm implements at farm machinery at present.

Summary of the invention

Unstable and the pretty troublesome shortcoming of replacing farm implements for the farm machinery walking that overcomes wheeled driving the utility model proposes a kind of crawler tractor that hangs the farm implements frame that has.

This crawler tractor that hangs the farm implements frame that has, comprise the power running gear and hang the farm implements frame, link to each other before and after them, it is characterized in that, the power running gear comprises creeper undercarriage, diesel engine is fixedly arranged on the creeper undercarriage upper stand, diesel engine links to each other with hydraulic power system by belt, diesel engine also links to each other by the power shaft of belt with gearbox one, the output shaft of gearbox one links to each other by the driving wheel of belt and creeper undercarriage, and diesel engine also links to each other by the power shaft of belt with gearbox two, and the diesel engine upper fixed has operating personnel's seat, seat the place ahead is equipped with operating grip, and the seat rear is equipped with protective cover; Hang the farm implements frame and comprise that is gone up a power transmission shaft, the output shaft of last power transmission shaft one end and gearbox two links to each other, the other end cross section of last power transmission shaft is square, be inserted in the top square hole of length adjuster, in the square hole of the bottom of length adjuster, be inserted with lower drive shaft, the other end of lower drive shaft links to each other with the farm implements gearbox, and the output shaft that the farm implements gearbox is logical is crossed belt and linked to each other with the farm implements axle; Farm implements gearbox top is equipped with upper support bar by pin-and-hole, and the other end of upper support bar links to each other with frame by pin-and-hole, and the upper support bar middle part is equipped with hydraulic jack by pin-and-hole, and the other end of hydraulic jack links to each other with frame by pin-and-hole; Two lower support bars about the bottom of gearbox two is equipped with by pin-and-hole, the other end of lower support bar links to each other with the farm implements cover by pin-and-hole, there is the farm implements installing plate at farm implements cover two ends, the farm implements installing hole is arranged on the farm implements installing plate, farm implements are two-part, two sections both sides that are installed in the farm implements gearbox respectively, farm implements one end is inserted on the farm implements axle, and the other end is inserted in the farm implements installing hole.

By elongating or shortening of hydraulic jack, can spur and lift on the upper support bar or descend, and make and lift on lower support bar and the farm implements frame or descend, thus the depth of regulating the farm implements farming; In the farm implements frame, various farm implements can be installed in addition, as Pu roll, rake, rotary tillage roll etc., changes also very convenient; Whole agricultural machinery is dragged by crawler belt, smooth running, and center of gravity is low, and handling safety can adapt to various landform.
