[0068] Please refer to Figures 1 to 7 , a new type of leek harvesting device, comprising:

[0069] A frame 1, with a plurality of wheels provided at its bottom,

[0070] A gathering mechanism 2, which includes two conical barrels 21 arranged at intervals. The conical bottoms of the conical barrels 21 face backward and are rotatably connected to the front of the frame 1. The surfaces of the conical barrels 21 are provided with spiral blades. The two conical barrels 21 rotate to receive the leeks to be harvested into the gaps between the spiral blades and gradually gather them together;

[0071] A cutting mechanism 3, which is arranged behind the gathering mechanism 2 and connected to the frame 1. The cutting mechanism 3 includes a cutting knife assembly and a tool rest traveling wheel 31. The tool rest traveling wheel 31 is used to travel on the ground, and the cutting knife assembly is higher than the bottom of the tool rest traveling wheel 31;

[0072] The first transmission mechanism 4 is inclinedly arranged on the frame 1. The first transmission mechanism 4 includes two sets of conveyor components arranged in parallel. Each conveyor component includes a plurality of first conveyor units 41, a plurality of second conveyor units 42, and a conveyor belt 43 tensioned between the two. Each of the first conveyor units 41 is coaxially arranged, and each of the second conveyor units 42 is coaxially arranged. The first transmission mechanism 4 can convert the cut leeks from an upright state to a toppled state and convey them upward and backward.

[0073] The ash spreading mechanism 5 includes a feeding port 51, an ash spreading pipe 52, and a screw conveyor 53. The ash spreading pipe 52 is connected to the bottom of the frame 1 and is located behind the cutting mechanism 3. The feeding port 51 is connected to one side of the ash spreading pipe 52. A plurality of ash outlets 521 are arranged along the length direction of the ash spreading pipe 52. The screw conveyor 53 is arranged in the ash spreading pipe 52 to convey the ash material in the feeding port 51 to each of the ash outlets 521.

[0074] And the packing mechanism 6 is arranged behind the first transmission mechanism 4 and is connected to the frame 1. The packing mechanism 6 is used for packing the cut leeks.

[0075] The new type of leek harvesting device travels on the ground through wheels, and completes the gathering, cutting, transmission, and packing of leeks within the device as the device advances.

[0076] The two conical barrels 21 inside the gathering mechanism 2 rotate towards each other, enabling the unfolded leeks to be gathered together for subsequent operations. There is a certain gap between the conical bottoms of the conical barrels 21 to prevent the leeks from being crushed by the two conical barrels 21. The leaves of the leeks are concentrated along the spiral grooves of their spiral blades and are conveyed backward as the vehicle moves forward. The roots of the gathered leeks are cut by the cutting mechanism 3. The cut leek leaves are clamped by two sets of conveying components of the first conveying mechanism 4 and conveyed backward and upward, and are changed from the upright state to the inclined state during the conveying process to facilitate subsequent packaging and transportation. The conveyor belts 43 tension and convey the first conveying unit 41 and the second conveying unit 42 in one-to-one correspondence. The number of conveyor belts 43 corresponds to the number of the first conveying unit 41 and the second conveying unit 42. The purpose of setting multiple first conveying units 41, multiple second conveying units 42, and the conveyor belts 43 tensioned between them is to widen the clamping surface for the leeks, flatten the leeks between the two sets of conveying components, and prevent their leaves from spreading outside the two sets of conveying components and being damaged. An outer casing is covered outside the first conveying mechanism 4. The feeding port 51 can be connected to one side of the casing. A certain amount of plant ash material is stored in the feeding port 51. As the vehicle moves forward, the screw conveyor 53 is started to evenly convey the plant ash in the feeding port 51 to each ash outlet 521. The ash outlets 521 are arranged facing the ground. Multiple rows of ash outlets 521 are provided on the ash spreading pipe 52, and multiple ash outlets 521 are evenly arranged in each row, so that the plant ash can be evenly spread on the ground of the cut leeks.

[0077] The new type of leek harvesting device gathers the leeks through two conical barrels 21 arranged at intervals and then cuts them, which is convenient for subsequent conveying and packing. During the conveying process, multiple sets of conveyor belts 43 are used for clamping and conveying to protect the leek leaves from being worn. And the ash spreading mechanism 5 spreads ash on the cut leeks, playing roles of nutrient supply, disinfection, and reducing the risks of leek head rot and mildew. The new type of leek harvesting device can perform the function of spreading plant ash for moisture and fertilizer preservation while being able to meet the requirements of harvesting leeks on the ground and packing them, improving production efficiency, ensuring the quality of leeks, and facilitating the growers to store and sell leeks.

[0078] In some embodiments, the cutting mechanism 3 includes a tool holder 32, a first tool body 33, a second tool body 34, a cam 35, and a cutting power member. The tool holder 32 is connected to the frame 1. The cutting power member is disposed on the tool holder 32 and is in transmission connection with the cam 35. A connecting ring is provided at the end of the first tool body 33, and the connecting ring is sleeved outside the cam 35. The cam 35 eccentrically rotates driven by the cutting power member and drives the first tool body 33 to move relative to the second tool body 34 to cut leeks. The first tool body 33 is attached above the second tool body 34, and a plurality of cutting edges are provided on both the first tool body 33 and the second tool body 34. The cam 35 reciprocally drives the first tool body 33 with the cutting power member, so that the leeks located between the first tool body 33 and the second tool body 34 are cut off.

[0079] In some embodiments, the cutting mechanism 3 is movably connected to the frame 1 through a connecting rod 37, and the cutting mechanism 3 walks on the ground through the tool rest traveling wheels 31 under its own weight. When the vehicle passes over uneven ground, the tool rest traveling wheels 31 travel on the ground, and the height of the cutting mechanism 3 is adjusted along with the undulation of the ground. The distance between the bottom of the tool rest traveling wheels 31 and the first tool body 33 is 20 cm.

[0080] In some embodiments, a plurality of the first conveying units 41 are disposed on a longitudinal axis 44, and the longitudinal axis 44 is rotatably connected to the frame 1; a plurality of the second conveying units 42 are disposed on a transverse axis 45, and the transverse axis 45 is rotatably connected to the frame 1. Both the first conveying unit 41 and the second conveying unit 42 are belt pulleys, and a sponge layer is further provided on one side of the conveyor belt 43 facing the outside of the belt pulley. The sponge layer can effectively protect the leeks from being squeezed.

[0081] In some embodiments, a plurality of the first conveying units 41 are arranged at intervals, and a plurality of the second conveying units 42 are arranged at intervals. That is, there is a certain interval between the conveyor belts 43 tensioned on the first conveying units 41 and the second conveying units 42, which can not only meet the clamping and conveying of the leaf parts of long strip-shaped leeks, but also reduce the contact area between the conveyor belts 43 and the leaf parts of the leeks, avoiding extrusion and damage.

[0082] In some embodiments, the novel leek harvesting device further includes a second transmission mechanism 7. The second transmission mechanism 7 is disposed between the first transmission mechanism 4 and the packing mechanism 6. The second transmission mechanism 7 is horizontally arranged and is used to convey the leeks on the first transmission mechanism 4 to the packing mechanism 6. The second transmission mechanism 7 can work intermittently. When the packing is in progress, the conveyance of leeks to it is stopped, and when the packing work is completed, the leeks are conveyed to it again.

[0083] In some embodiments, the packing mechanism 6 includes a receiving power member 61, a crank connecting rod 62, a receiving frame 63 and a stop block 64. The receiving power member 61 and the receiving frame 63 are connected to the frame 1. The opening of the receiving frame 63 faces the first transmission mechanism 4. The stop block 64 is movably connected to the opening of the receiving frame 63. One end of the crank connecting rod 62 is connected to the receiving power member 61 for transmission, and the other end of the crank connecting rod 62 is connected to the stop block 64. The stop block 64 connects the receiving frame 63 and the first transmission mechanism 4 / second transmission mechanism 7. As the stop block 64 rotates towards the opening of the receiving frame 63, the leeks entering the receiving frame 63 can be further regularized, facilitating bundling.

[0084] In some embodiments, the packing mechanism 6 further includes a packing power member 65, a rocker arm 66, a bundling tape 67 and a packing cutter. The packing power member 65 is connected to the frame 1. The rocker arm 66 is in transmission connection with the packing power member 65. The bundling tape 67 is sleeved on the rocker arm 66. The packing cutter is located on one side of the receiving frame 63 and is used to cut the bundled bundling tape 67. The bundling tape 67 can be made of adhesive tape. After the rocker arm 66 swings, the bundling tape 67 is wound around the roots of the leeks and cut by the packing cutter to complete the packing work.

[0085] In some embodiments, the two conveying components are synchronously driven. This protects the leeks from rubbing against the surface of the conveyor belt 43 in the first transmission mechanism 4.

[0086] In some embodiments, the two conical barrels 21 rotate in opposite directions. This facilitates the gathering of the scattered leaf parts of the leeks.

[0087] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of the present application, the patent protection scope of the present application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the essential concept of the present application, using the content recorded in the text and drawings of the specification of the present application, as well as any technical solutions directly or indirectly implementing the above embodiments in other related technical fields, are included in the patent protection scope of the present application.
