The southern hilly areas, which are mainly vegetable-growing, are facing the current situation of "no machine available" for the planting and harvesting of many types of vegetables. Although the degree of mechanization of agricultural harvesting in my country is increasing year by year, the overall mechanization level is still far behind that of developed countries, especially in transplanting and harvesting, which are still semi-automated and require manual collaboration to complete;

A motor is installed below the rear end of the sprocket wheel (232) for driving the sprocket wheel (232). 2) driving the toothed cutting blade (233) and the clamping conveyor belt (242) to rotate through the transmission (234), so that one motor drives the toothed cutting blade (233) and the clamping conveyor belt (242) to rotate, and the two motors in one channel rotate in opposite directions, so that the toothed cutting blade (233) and the clamping conveyor belt (242) rotate inwardly, and the leafy vegetables are harvested and transported. The front end of each channel carrier (231) is provided with two plow points (235), which are used to cooperate with the vehicle body (1) to move forward, so as to shovel up the leafy vegetables and expose the root system for easy cutting; Two conveying channel devices (24) are respectively installed above the channel carrier (231), and clamping conveyor belts (242) are arranged on both sides of the two harvesting channels (241). The two conveyor belts clamp the leafy vegetables by friction and rotate synchronously in opposite directions to convey the leafy vegetables to the baffle conveyor belt (21); A rubber roller device (25) is installed on the front side of the conveying channel device (24) and above the toothed cutting blade (233), and mainly comprises: two rubber rollers (251), four sliders (252), four slide bars (253), two fixed bars (254), four fixed slideways (255), four screw springs (256), eight fixing members (257), four slideway fixing plates (258), and two connecting plates (259). The two fixed slideways (255) are connected by the fixing bars (254) and the connecting plates (259), and the slide bars (253) are arranged inside the fixed slideways (255). A screw spring (256) is sleeved on the slide bar (253), and the slider (252) cooperates with the slide bar (253) to ensure that the slider (252) can slide along the slideway (2551) inside the fixed slideway (255). A rubber roller (251) is connected between the two sliders (252), and the rubber roller (251) can rotate between the two sliders (252). A small motor is installed inside the slider (252) to drive the rubber roller (251) to complete the inner rotation, so that the leafy vegetables are harvested by the rubber roller device (25) in cooperation with the toothed cutting blade (233) and rolled into the conveying channel device (24).

4. The detachable harvester and transplanter as claimed in claim 1, characterized in that: The recovery device (4) mainly comprises: a front lifting baffle (411), a rear lifting baffle (412), a conveyor belt fixing frame (413), a 90° turning conveyor belt (42), a transverse conveyor belt (41), a recovery basket (43) and a motor; the transverse conveyor belt (41) is installed at the front end of the working platform (33) and the rear end of the baffle type conveyor belt (21); the front lifting baffle (411) and the rear lifting baffle (412) are installed at the front and rear sides of the transverse conveyor belt (41), and baffle racks (416) are provided on both sides of the front lifting baffle (411) and the rear lifting baffle (412); the baffle racks (416) are meshed with the gears (414) in the conveyor belt fixing frame (413); the gears (414) are installed on the gear fixing member (415); the motor is installed at the transverse conveyor belt (41) and the rear lifting baffle (412) is installed at the rear end of the baffle type conveyor belt (21); The lower end of the belt (41) is used to drive the gear (414) to rotate, and the lifting and lowering of the front lifting baffle (411) and the rear lifting baffle (412) are controlled by the motor; when transplanting, the front lifting baffle (411) is raised, the rear lifting baffle (412) is lowered, and the recovery device (4) is used to recover the seedling tray (32); when harvesting, the front lifting baffle (411) is lowered, the rear lifting baffle (412) is raised, and the recovery device (4) is used to transport the harvested leafy vegetables; a 90° steering conveyor belt (42) is installed at the end of the transverse conveyor belt (41) to realize the steering transportation of the seedling tray (32) and the leafy vegetables; on the right side of the vehicle body (1), below the 90° steering conveyor belt (42), a recovery basket (43) is installed to store the seedling tray (32) and the leafy vegetables.
