Description

Improved Machine both for mowing and raking

Technical field

The utility model belongs to the improvement of the Machine both for mowing and raking tool that gathers in herbage, particularly improved Machine both for mowing and raking.

Background technology

The Machine both for mowing and raking of present general harvesting herbage is that Machine both for mowing and raking and tractor adopt rearmounted half suspension arrangement, and the latch that passes through the towing plate lower carriage connects, this machinery has only a support wheel, the load of machinery is born by towing plate lower carriage and support wheel, discontinuity, the support of Machine both for mowing and raking is fragile; The hoisting depth of existing Machine both for mowing and raking assembly utilizes the rearmounted suspension hydraulic hoisting mechanism of tractor to realize, adjust the height of complete machine by the hydraulic pressure system according to the situation of the face of land and herbage, but the height of adjusting is limited, and when running into superelevation, Cardan shaft damages easily; Machine both for mowing and raking mechanism adopts air pressure control, needs source of the gas independently is set, and makes entire mechanism complicated.In addition, the buck rake speed of swaying is very fast, less stable; Hug the unreasonable structure of careless elastic claw and pressure pole, influenced the quality of service life and work, serviceability is poor, and operating efficiency is lower.

The utility model content

The purpose of this utility model is to provide a kind of improved Machine both for mowing and raking, and is not only simple and reasonable, and serviceability is good, and the operating efficiency height, and cost is low, long service life.

The purpose of this utility model is achieved in that a kind of improved Machine both for mowing and raking, an end that comprises support assembly and the universal drive shaft of installing on frame is connected with tractor output shaft, the other end moves back and forth by the cutter of belt transmission cutter, the rearmounted towing plate of tractor is connected with frame by Connection Block, the wheel of two symmetries is installed in the bottom of frame, hinged oil cylinder on frame, its other end is by the Connection Block of the articulated cutter of jockey, articulated sport on the cantilever of frame rear portion symmetry, be articulated on the frame by hook in reverse affixed depression bar end on the sport, articulated pressure joint frame on the frame of sport bottom, the upper end of two gag lever posts vertically is fixed in respectively on the frame symmetry cantilever, its lower end has block, and gag lever post matches with the sliding sleeve that is fixed in pressure joint frame both sides respectively.

Because frame of the present utility model directly is connected by the rearmounted towing plate of Connection Block and tractor, do not adopt the rearmounted suspension arrangement of former Machine both for mowing and raking and tractor to be connected, two wheels are installed on the frame, frame is stressed evenly, it is not fragile to connect support, has increased service life.The utility model is by the Connection Block of the articulated cutter of hydraulic jack, adopt the height of hydraulic control cutter, the operator can use the height of hydraulic control cutter easily according to the situation of the face of land and herbage, and cutter height overhead can be adjusted easily.

Because the hydraulic oil control oil cylinder that adopts the oil pump of tractor itself to supply with does not need independently oil supply system, simple in structure, maneuvering performance is reliable and stable.Because sport is hinged on the cantilever of frame rear portion symmetry, controls sport by manual depression bar, when sport was not worked, the hook that only needs the depression bar on the sport is pressed down the depression bar end was articulated on the frame, and sport is upwards lifted.When the needs sport is worked, the hook of depression bar end and the link of frame are broken away from, sport is descended, can hug grass work.The sliding sleeve of hinged pressure joint frame both sides matches with the vertical gag lever post that the end has block on the sport lower framework.

Uneven or when barrier is arranged when ground, press the other end of joint frame to rotate around pin joint, can not make and press the joint frame uneven or have barrier to damage because of ground.When work, press the other end of joint frame to fluctuate according to the quantity that reclaims herbage thereupon, actual scope of floating is controlled by gag lever post.The utility model is simple and reasonable, and serviceability is good, and flexible operation uses reliably, and manufacturing cost is lower, operating efficiency height, long service life.
