[0030] The upper end of the extension frame 2 is hinged to one end of the adjusting rod 5.

[0031] It should be noted that the adjusting lever 5 is existing technology and is commonly used for connecting agricultural machinery and tractors.

[0032] The fixed ear 3 is hinged to one end of the traction arm 6.

[0033] Working principle: Before use, the equipment is connected and fixed to an external traction machine, such as a tractor, by means of the traction arm 6 hinged to the fixed ear 3 and the adjusting rod 5 hinged to the extension frame 2, thus completing the connection of the equipment. According to the weeding depth requirements between alfalfa rows, the weeding component 4 is adjusted. The specific operation is as follows: First, pull the locking plate 4022 of the locking part 402 away from the limiting sleeve 401, so that the end of the locking plate 4022 is disengaged from the groove 4031 on the surface of the connecting arm 403. At this time, the spring 4025 on the fixing rod 4023 is compressed. After moving the connecting arm 403 up and down to the appropriate height, the locking plate 4022 is released. The spring 4025 returns to its original position, causing the locking plate 4022 to return to its original position. Its end is re-engaged into the corresponding groove 4031, thereby fixing the connecting arm 403. Then, the adjustable actuating element 408 is operated as follows: loosen the screw 4083 on the side wall of the sleeve 4081, move the actuating plate 4082 to a suitable height on the connecting arm 403, and then tighten the screw 4083 to press it against the surface of the connecting arm 403, thus completing the positioning of the actuating plate 4082. During operation, the external traction machinery drives the entire equipment to move, and the shovel 407 cuts into the soil, severing the roots of weeds. At the same time, the soil scooped up by the shovel 407 will roll over and fall to the rear, breaking up the compacted layer, realizing simultaneous cultivation and weeding without manual operation, thus improving work efficiency.

[0034] Secondly, when the equipment is working, the two ends of the deflector plate 4082 will push away the alfalfa heads located on both sides of the row in advance in front of the blade 407, so as to prevent the alfalfa heads from getting tangled on the connecting arm 403 and breaking off when the equipment moves forward.
