Because the collection loading platform has certain contained angle with ground, when receiving the pressure of first row bale, the dolly can slide backward under the effect of gravity, and displacement distance is the distance of one bundle bale, then the second row bale upset through the upset platform, reaches collection loading platform, and the dolly moves the distance of one bundle bale backward again, repeats above-mentioned step, will collect loading platform 5 to fill up the bale. The vertical baffle straw bale limiting device 6 plays a role in limiting and arranging, so that each row of straw bales orderly enter the collecting and carrying platform 5 of the pickup machine, and the straw bales on the collecting and carrying platform 5 are orderly collected, so that secondary stacking is realized.

5) The grass pressing fork 7 is fixedly connected with left and right gate posts in the collecting and carrying platform guard rail 52 through a pin shaft, the grass pressing rod is adjustable, the length of the pressing rod can be adjusted according to the height of the grass bundle, when the grass bundle is turned to the collecting and carrying platform 5 from the turning platform 4, the pressing rod can be pressed above the grass bundle, the grass bundle can be pressed, and the grass bundle can be prevented from falling off in the running process.

6) After the grass collection and carrying platform 5 is full, the tractor drives the chassis 1 to run to a specified place, the collection and carrying oil cylinder 54 drives the bottom platform 51 to turn over, and the push rod mechanism withdraws the grass bundles from the collection and carrying platform, so that the purpose of unloading is achieved.
