Description

A kind of building grass machine of beating

Technical field

The utility model relates to the grass harvester tool, is that a kind of peace is hung on the double Rake of hugging grass of beating the grass of tractor with small four wheels rear portion specifically.

Background technology

There are two kinds of mowers that hang on the tractor rear portion all not have the wheel that travels at present, so the trailing wheel of tractor also must rise and fall when landform rises and falls, at this moment it is indefinite that the tool section part that hangs on the mower of tractor back and mowing also and then rises and falls, can occur tractor that tool section does not also come and that mowing is is just risen and fallen like this and take up, so the mowing rate is not high.This in addition suspension mower is single mower, and the grass that knocks down also need be pulled buck rake in addition and be hugged grass, and the cost that has so promptly increased the equipment of beating the grass is inconvenient to again use.These two kinds of mowers are to do power by the power transmission shaft that tractor rear axle portion stretches out backward to drive at present in addition, and the back axle of some tractor does not have power transmission shaft, therefore just can't use this mower.

Summary of the invention

The purpose of this utility model provides a kind of can beating the grass, and hugs grass again simultaneously, need not to hang in addition rake, and the cuttting cleaning rate height, the Rake that all tractor with small four wheels all can be supporting.

Rake of the present utility model comprises frame, the back shaft on the tractor rear axle, and rake is used for the clutch of lifting rake, the axle bed of peace axle, cutter head, tool section, compositions such as power take-off.

It is characterized in that: machine adds by bolt pacifies intrinsic support arm, also porose on the support arm, and this borehole jack is on the fulcrum on the tractor rear axle, on frame, be equipped with the axle that travels, be equipped with the wheel that travels on the axle, the frame back rest is provided with supporting seat, on supporting seat, be equipped with buck rake, be provided with the clutch of control rake lifting at the axle head of the axle that travels, on clutch, be provided with the pull bar of pulling rake, on clutch, also be provided with trip(ping) lever, on tractor, be provided with manual type and control thick stick, and control thick stick and be connected with trip(ping) lever;

Feature of the present utility model also is, also is equipped with cutter head, tool section, the mower that crank, connecting rod etc. the confession beat the grass on frame simultaneously; On frame, be equipped with two axle beds, an axle bed is positioned on frame top, another axle bed is positioned on the frame below it, and it is axially identical, the power take-off that stretches out later from tractor is connected so that universal joint is coaxial with the axle head on the frame top axle bed, and this other end is equipped with belt pulley, also is equipped with belt pulley at the axle head of axle bed down, and should rotate with the belt pulley coupling on the frame top axle bed by wheel, the other end of following seat axle is equipped with the connecting rod of crank and driving knife bar work.

Described Rake is characterized in that: the control rake is driven the trip(ping) lever that falls, and fixes seat and controls on the sole that thick stick can be arranged on tractor, establishes a pedal controlling the thick stick end.

The utility model has following beneficial effect compared with prior art:

1, because on frame, is equipped with machineries such as buck rake and mower simultaneously, so have a tractor serves several purposes, advantage that equipment cost is low.

2, because being housed, the frame of buck rake and mower adopted anterior suspension rear portion to prop up the structure on ground, be exactly that the frame leading edge is pacified on two fulcrums that are hung on the tractor rear axle by bearing, the rear portion frame is equipped with a wheel that travels on ground, be flattened on when landform rises and falls that tool section that ground moves forward can be sensitive along with fluctuating, so the cuttting cleaning rate height.

3, the operation power because of mower tool section on this machine does not adopt the power take-off on the tractor rear axle to drive, and the power that adopts engine directly to export backward through power transmission shaft, so but the equal this Rake of adapted of all four-wheel tractors.

4, because this advantage of a tractor serves several purposes arranged, the tractor that also has unpowered output shaft on the back axle also can this advantage of adapted, uses flexibly and benefit such as convenient so have.
