Abstract
The utility model relates to a built-in downward cutting mechanism of a combined harvester of rice and wheat, comprising a downward cutting bar, a left support arm, a right support arm, a rotation shaft, a crank arm, a lower crank arm seat, an upper crank arm seat, a chassis frame, a left caterpillar and a right caterpillar. The left support arm and the right support arm are mounted not over the middle between both ends of the left and the right caterpillars. When the downward cutting mechanism of the harvester cuts stubble, the stubble falls over the front ends of the left and the right caterpillars, and is pressed at the bottoms of the caterpillars without being locked on the support arms and the crank arm because the support arms and the crank arm are concealed between the left and the right caterpillars, and the downward cutting bar can not collect grass. The built-in downward cutting mechanism is simple in structure and reliable in performance.
Description
Technical field
The utility model relates to the crops rice/wheat combine, further is meant the built-in cutter knife mechanism down that is contained in rice/wheat combine.
Background technology
Upper cutter knife on the existing full feeding rice wheat combine cuts off the back threshing with crops such as the rice wheat point of raising, the following cutter that is contained in the upper cutter knife back lower place cuts surplus standing grain stubble level land with upper cutter knife and cuts off, satisfy and plough the requirement of planting again again, but the cutter supporting arm exposes to the top and the front end of crawler belt under in the prior art, supporting arm and connecting lever have the careless phenomenon of extension, following knife strap has long-pending careless phenomenon, and long-pending grass pushes over the crops of not cutting off in the place ahead and causes the loss of standing grain fringe.
The utility model content
The technical problems to be solved in the utility model is, defective at the prior art existence, a kind of built-in cutter knife mechanism down of rice/wheat combine is proposed, it can make the standing grain stubble that cutter cuts off under the grain header be unlikely to hang on supporting arm and the connecting lever, there is not long-pending careless phenomenon on the following knife strap yet, the standing grain stubble that cuts off can lodge and be pressed in the crawler belt bottom at left and right sides crawler belt front end, drains smoothly, in order to harvesting.
The technical solution of the utility model is that the built-in cutter knife mechanism down of described rice/wheat combine comprises knife bar, left side supporting arm, right supporting arm, rotating shaft, connecting lever, following connecting lever seat, last connecting lever seat, chassis main frame, left and right sides crawler belt is formed, it is characterized in that, described left supporting arm, right supporting arm, last connecting lever seat, following connecting lever seat are installed in the centre of the rear and front end that does not exceed left crawler belt, right-hand track chiain.
Below the utility model made further specify.
Referring to Fig. 1 to Fig. 4, the built-in cutter knife mechanism down of described rice/wheat combine, comprise knife bar 1, left side supporting arm 2, right supporting arm 3, rotating shaft 4, connecting lever 5, following connecting lever seat 6, last connecting lever seat 7, chassis main frame 8, left and right sides crawler belt 15,16 form, it is characterized in that, left side supporting arm 2, fixedly connected with rotating shaft 4 two ends respectively in the upper end of right supporting arm 3, left side supporting arm 2, the lower end of right supporting arm 3 is fixedly connected with left transverse arm 12 respectively, right transverse arm 13, described left transverse arm 12, the front end of right transverse arm 13 is fixedlyed connected with knife bar, when knife bar 1 during to the lower position, left and right sides supporting arm 2,3 become 90 ° with the horizontal plane of chassis main frame 8, described rotating shaft 4 is movably arranged on the chassis main frame 8, vertical with frame longeron 9, described left supporting arm 2 and right supporting arm 3 are installed in and do not exceed left and right sides crawler belt 15, the centre of 16 rear and front ends, Top Crossbeam 14 is equipped with on the top of left side supporting arm 2 (or right supporting arm 3), described connecting lever seat 6 down, last connecting lever seat 7 is installed in respectively on left transverse arm 12 and the Top Crossbeam 14 up or down, and its position does not exceed left and right sides crawler belt 15,16, connecting lever 5 is installed in down connecting lever seat 6, between the last connecting lever seat 7, described connecting lever 5 is made reciprocating swing by interlinked mechanism 10, and connecting lever 5 is connected with blade 11 on being placed in knife bar 1, and blade 11 is reciprocating, cut off the standing grain stubble, drain smoothly.
Design principle of the present utility model is, referring to Fig. 1,2,3, when cutter under the grain header cuts off the standing grain stubble, because supporting arm and connecting lever are built between the crawler belt of the left and right sides, the standing grain stubble that cuts off can lodge and be pressed in the crawler belt bottom at left and right sides crawler belt front end, can not hang on supporting arm and the connecting lever, long-pending careless phenomenon can not appear in knife bar yet.
As known from the above, the utility model is a kind of built-in cutter knife mechanism down of rice/wheat combine, make the standing grain stubble lodging crawler belt front end that is cut off be pressed in the crawler belt bottom and drain smoothly, and simple in structure, dependable performance.
