A connecting hole is provided at the small end thereof, and is fixedly connected to the large gear 42 through the connecting hole, so that it rotates with the large gear 42. The two eccentric wheels 44 are respectively arranged in the sliding grooves 312 of the two cutting blades 31. The small gear 43 is driven to rotate by the first motor 5, and the small gear 43 drives the large gear 42 The eccentric wheel 44 rotates and drives the eccentric wheel 44 to rotate. The eccentric wheel 44 rotates in the sliding groove 312, driving the two cutting blades 31 to reciprocate. The guide groove 311 cooperates with the bolt 34 to control the sliding direction of the cutting blade 31, so as to achieve cutting. A plurality of blade teeth 313 are arranged on both sides of the two cutting blades 31. The plurality of blade teeth 313 on both sides of one cutting blade 31 are staggered with the plurality of blade teeth 313 on both sides of the other cutting blade 31.

[0042] The eccentric wheel 44 cooperates with the sliding groove 312: when the eccentric wheel 44 is upward, the blade is centered and does not move. When the eccentric wheel 44 rotates 90 degrees and turns left, the blade moves forward 16 mm. When the eccentric wheel 44 rotates 180 degrees and turns downward, the blade moves back and is centered. When the eccentric wheel 44 rotates 270 degrees and turns right, the blade moves backward 16 mm. In this way, the eccentric wheel 44 rotates and the blade reciprocates back and forth.

The conveyor belt 61 is provided with a plurality of baffles 611 to prevent vegetables from sliding off. The driven roller 63 is close to the reciprocating cutter. It is arranged next to the cutting knife 3 and has a horizontal height not much different from that of the reciprocating cutting knife 3, so that the stems and leaves after cutting can fall onto the transmission belt. The active roller 62 is arranged close to the placement rack 11 and is higher than the placement rack 11, so that the stems and leaves on the conveyor belt 61 can fall into the collection frame on the placement rack 11.

The inner width of the conveyor belt 61 is 400mm, and the outer part includes an aluminum alloy profile with a width of about 500mm. The conveyor belt 61 is 1 meter long. There are many materials to choose from for the conveyor belt 61. Ordinary PVC belts are made of PVC polyvinyl chloride and industrial polyester cloth. They are wear-resistant, heat-resistant, and oil-resistant, and are not easy to deform. Lawn-pattern anti-slip belts can also be used, and the spacing between the baffle bars is 250mm.

[0046] As a further development of the present embodiment, the power supply 7 is connected to the first motor 5 and the second motor 66 through a switch, and the first motor 5 and the second motor 66 are rotated simultaneously through a switch, and the first motor 5 and the second motor 66 are both DC motors, so that the power supply 7 is uniformly powered by lithium batteries, so that the transmission belt and the cutting blade 31 move simultaneously, and the second motor 66 is controlled by a speed regulator control module, which can enable the second motor 66 to have forward, stop, and reverse switches, and the speed can be adjusted to high speed, low speed, and medium speed.

[0047] The working principle of this embodiment is as follows: a collection frame is placed on the placement rack 11, the switch is turned on, and the first motor 5 and the second motor 66 are started at the same time. The first motor 5 drives the small gear 43 to rotate, and the small gear 43 drives the large gear 42 to rotate. The eccentric wheel 44 rotates with the rotation of the large gear 42, and the eccentric wheel 44 drives the cutting blade 31 to reciprocate to achieve a cutting effect. The second motor 66 drives the driven gear 621 to rotate through the chain 65, and the driven gear 621 drives the active roller 62 to rotate, thereby driving the conveyor belt 61 to transmit. At this time, the handle 12 is pushed forward, and the vegetables will fall on the conveyor belt 61 after being cut. The vegetables are transported by the conveyor belt 61 and fall into the collection frame.
