[0015] (1) By fixing the side plates longitudinally at the front end of the shaft sleeve, when holding the handrail and pushing the cart with tires to move, the motor is started first, and then the screw in the moving chamber is rotated. Under the restriction of the moving chamber, the shaft sleeves on both sides can be forced to slide horizontally towards each other, and the distance between the two side plates can be adjusted according to the area of the alfalfa to be harvested, so that the upper feeding structure and the lower blade are forced to gather the alfalfa and cut it at the same time, and then gather and bundle it with the help of symmetrically connected clamping blocks, which can be adjusted according to the harvesting range;
[0016] (2) By placing blocks horizontally in the inner cavity, the blocks are accumulated in the storage tank before entering the tube body and fall down with gravity. After falling into the inner cavity, when the cylinder is opened, the piston rod with the push block is gradually pushed toward the notch. When the alfalfa is close to being gathered and cut, it is locked and fixed on both sides of the block. At this time, the latch is also embedded in the corresponding slot, which is convenient for bundling and can be used multiple times after unloading. After the bundling is completed, the replacement block will also enter the notch, which is convenient for next use;
[0017] (3) By installing slide rails longitudinally on both sides of the center of the front end of the cart, the balance rod with a threaded groove is vertically lifted above the rotating screw under the restriction of the slide rails on both sides, so that the sleeve block sleeved on the outside of the slide rail is also vertically lifted under the action of the connecting rod. The rubber patches set on both sides of the slide rail can also prevent the sleeve block from falling. The cutting and bundling height of the device is changed according to the height of the rhizomes to be cut, thereby avoiding cutting of alfalfa flowers and fruits and ensuring the integrity of the plants.
