Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides a spinach harvester. Figure 1-Figure 5As shown, the harvester comprises a body 1, wheels 12 fixedly arranged at the corners of the body 1, a notch 11 provided on the body 1, a handle 13 symmetrically fixedly arranged on one side of the body 1 corresponding to the notch 11, a collection box 2 for collecting spinach placed on the body 1 and located between two handles 13, a harvesting mechanism 3 for harvesting spinach arranged at a position corresponding to the notch 11 on the body 1, and a transport mechanism 4 arranged between the harvesting mechanism 3 and the collection box 2 for transporting the spinach on the harvesting mechanism 3 to the collection box 2; the harvesting mechanism 3 comprises a wheel 12 fixedly arranged at a position corresponding to the notch 11 on the body 1, ... wheel 12 fixedly arranged at a position corresponding to the notch 11 on the body 1, and a wheel 12 fixedly arranged at a position corresponding to the notch 11 on the body 1, and a wheel 12 fixedly arranged at a position corresponding to the notch 11 on the body 1, and a wheel 12 fixedly arranged at a position corresponding to the notch The first support frame 31 and the second support frame 32 are located at the positions on both sides of the corresponding slot 11 on the machine body 1, the first triangular retainer 33 and the second triangular retainer 34 are rotatably connected to the first support frame 31 and the second support frame 32 on the side close to each other, three blades 35 are fixedly arranged between the first triangular retainer 33 and the second triangular retainer 34 and distributed in a ring shape, and a driving component 36 is arranged on the machine body 1 and located on one side of the first support frame 31 for driving the first triangular retainer 33 to rotate so that the three blades 35 rotate in sequence and pass through the transport mechanism 4.

[0030] When in use, firstly, due to the design of the wheel 12, the staff can hold the handle 13 and push forward to push the entire machine body 1 to the field where spinach is to be harvested. Then, the driving component 36 is started to drive the first triangular holder 33 to rotate. Under the rotation of the first triangular holder 33, the three blades 35 connected between the first triangular holder 33 and the second triangular holder 34 can be evenly flipped. At this time, the staff holds the handle 13 and keeps pushing the machine body 1 forward. Therefore, when the machine body 1 moves forward, the spinach passing through the slot 11 can be harvested by the three rotating blades 35, and the harvested spinach will naturally remain on the blades 35. When each blade 35 passes through the transport mechanism 4 in turn, the spinach can fall from the blade 35 onto the transport mechanism 4. Afterwards, the harvested spinach can be automatically collected in the collection box 2 through the transmission of the transport mechanism 4. During the harvesting process, a new collection box 2 can be replaced for collection according to the collection situation of the collection box 2.

At this time, the output shaft of the motor 365 transmits the rotational power to the worm 362 through the connection of the coupling 364. When the worm 362 receives the power and starts to rotate, the worm gear 363 meshing with it also rotates. Since the worm gear 363 is fixedly mounted on the first triangular holder 33, the first triangular holder 33 and the blade 35 thereon can start to rotate. Then, the operator manually pushes the entire machine body 1 forward, and the rotating blade 35 can realize the automatic harvesting of spinach. After the harvesting is completed, the motor 365 can be paused.

[0032] Furthermore, the transport mechanism 4 includes a support plate 41 fixedly mounted on the body 1 and located between the first support frame 31 and one of the handles 13, a plurality of support shafts 42 fixedly connected to the support plate 41 on one side close to the second support frame 32, and a roller 43 rotatably connected to the support shaft 42; the plurality of support shafts 42 are distributed in an inclined linear array, and the lower inclined ends of the plurality of support shafts 42 are connected to the collection box 2; when the start motor 365 drives the three blades 35 to rotate to harvest spinach, the spinach cut by the blades 35 will remain on the corresponding blades 35, however, as the motor 365 continues to drive, each blade 35 for cutting spinach will rotate downward in turn and pass through the plurality of rollers 43, when the blades 35 pass through the plurality of rollers 43, the spinach remaining on the surface of the blades 35 can automatically fall on the plurality of rollers 43, and then, under the action of the inclined setting of the plurality of support plates 41 and the rollers 43, the spinach falling on the plurality of rollers 43 can naturally flow into the collection box 2 for collection under the rolling action of the rollers 43.

[0033] In order to ensure the rotation of the roller 43, the transport mechanism 4 also includes a rubber sleeve 44 sleeved on the end of the support shaft 42 close to the second support frame 32; the design of the rubber sleeve 44 can prevent the roller 43 from falling from the end of the support shaft 42 close to the second support frame 32 during rotation.

[0034] In addition, in order to ensure that the spinach on the blade 35 can be smoothly transferred to the roller 43, the blade 35 has a plurality of gaps 351 adapted to the plurality of rollers 43; due to the design of the gaps 351, when each blade 35 rotates to the roller 43, the blade 35 can smoothly pass through between the rollers 43, while allowing the spinach on each blade 35 to stay on the surface of the roller 43.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
