For the sake of convenience, in the present invention, only the application of the low-loss stem-harvesting device for flue-cured tobacco in the field of agricultural machinery technology is used as an example for explanation. The principle of applying the low-loss stem-harvesting device for flue-cured tobacco to other types of equipment is essentially the same as the principle of applying it to the field of agricultural machinery technology, and will not be described in detail here.

[0032] See also Figures 1 to 5 , Figure 1 This is a structural schematic diagram of a low-loss stem-harvesting device for flue-cured tobacco in an embodiment of the present invention. The low-loss stem-harvesting device for flue-cured tobacco includes a mobile trolley 1, a collecting box 2, a material guiding assembly 3 and a cutting assembly 4. The collecting box 2 is connected to the mobile trolley 1, and the top of the collecting box 2 is open. The material guiding assembly 3 includes two material guiding shells 31. The two material guiding shells 31 are parallel to each other and spaced apart, and are both connected to the mobile trolley 1. The two material guiding shells 31 together form a material guiding gap 32 for guiding materials. One end of the material guiding gap 32 protrudes from the mobile trolley 1, and the other end extends in a direction close to the collecting box 2. The cutting assembly 4 is connected to the mobile trolley 1 and is arranged on the extension path of the material guiding gap 32 for cutting materials.

[0033] In this device, a collecting box 2 is provided on the mobile trolley 1, and two material guide shells 31 are provided on the mobile trolley 1 at intervals from the collecting box. One end of the material guide shell 31 protrudes from the front end of the mobile trolley 1, and the other end is extended in the direction close to the collecting box 2. A material guide gap 32 is formed between the two material guide shells 31, which is used to guide the material into the material guide gap 32. A cutting component 4 is also provided on the extension path of the material guide gap 32, which is used to cut off the material entering the material guide gap 32 and drop it into the collecting box 2 to be collected.

[0034] Compared with the prior art, a material guide shell 31 and a collection box 2 are provided on the mobile trolley 1, and a cutting assembly 4 is also provided on the extension path of the material guide gap 32, so that the material can be guided into the material guide gap 32 as the trolley moves. The material entering the material guide gap 32 can be automatically cut or chopped by the cutting assembly 4 after moving relative to the mobile trolley 1, and thus collected by the collection box 2. The operation is convenient, and can solve the problem in the prior art that it is inconvenient to operate because it is necessary to control the movement of the harvesting device during use and also to pull the push-pull rod of the scissor assembly at intervals to drive the knife body to cut the tobacco leaves with stems to complete the harvesting.

[0035] In this embodiment, the movable vehicle 1 includes a bracket 11 , two movable wheels 12 , two handrails 13 , and two linear drive units 14 .

[0036] Among them, the bracket 11 is connected to the collection box 2 and has a connecting gap connected to the material guide gap 32. The two moving wheels 12 are respectively arranged on both sides of the bracket 11 and are rotatably connected to the bracket 11. The two handrails 13 are parallel to each other and arranged at intervals, and are both connected to the collection box 2.

[0037] The moving wheel 12 is connected to the collecting box 2 through the bracket 11. At the same time, the bracket 11 is used to support and connect to the material guide shell 31 and the cutting assembly 4, playing a supporting and connecting role.

[0038] Furthermore, a material guiding channel communicating with the material guiding gap 32 is provided in the middle of the bracket 11 , so that the mobile vehicle 1 can smoothly pass over the harvested material.

[0039] In one embodiment, Figure 1 、 Figure 2 As shown, the linear drive part 14 has a fixed end and a telescopic end. The fixed ends of the two linear drive parts 14 are respectively connected to the moving wheel 12, and the telescopic ends are both connected to the bracket 11. The telescopic parts of the two linear drive parts 14 can be synchronously extended or shortened relative to their fixed ends, so as to drive the bracket 11 to rise and fall relative to the moving wheel 12.

[0040] The two linear drive parts 14 can move synchronously, so that the support 11 can be raised or lowered relative to the moving wheel 12, thereby being applicable to the harvesting of plants at different heights.

[0041] Furthermore, the linear drive unit 14 here is a common and easily purchased device on the market, which belongs to a conventional setting well known to those skilled in the art and will not be described in detail.

[0042] Furthermore, the mobile vehicle 1 can be driven by manpower, or by a diesel engine or an electric motor, which will not be described in detail here.

[0043] In one embodiment, Figure 4 As shown, one side of the collecting box 2 is connected to the material guiding gap 32, and a plurality of slag leakage holes are opened at the bottom of the collecting box 2.

[0044] The side of the collecting box 2 close to the harvesting component is connected to the material guide gap 32, so that the cut or chopped materials can be automatically poured into the collecting box 2 and collected together due to inertia as the mobile cart 1 moves forward. In order to improve the harvesting efficiency, the cut or chopped materials can also be pushed into the collecting box 2 and collected together with manual assistance. I will not go into details here.

[0045] Furthermore, a plurality of slag discharge holes are provided at the bottom of the collecting box 2 , which can discharge the broken branches, rotten leaves or soil etc. in the collection process out of the collecting box 2 , thereby reducing the weight of the materials in the collecting box 2 .

[0046] In this embodiment, the material guiding shell 31 has a first segment and a second segment. The second segment is arranged farther away from the collection box 2 than the first segment and protrudes from the front end of the support 11. The two first segments are parallel to each other and arranged at intervals, and are both connected to the support 11. A material guiding gap 32 is formed between the two first segments. The two second segments are respectively connected to the two first segments and form a flared opening, and the size of the opening gradually decreases in the direction close to the collection box 2.

[0047] The front end of the material guiding shell 31 forms a flared opening, which can effectively guide the material into the material guiding gap 32 and improve the success rate of the cutting device automatically cutting or chopping the material.

[0048] Specifically, the cross-section of the material guiding shell 31 is in a "C" shape.

[0049] In one of the embodiments, please refer to Figure 2 、 Figure 3 , the material guiding component 3 further includes a plurality of clamping parts 33 and two circulating conveyor belts 34. The plurality of clamping parts 33 are evenly distributed on the opposite sides of the two material guiding shells 31. The circulating conveyor belts 34 are arranged corresponding to the material guiding shells 31 one by one. The circulating conveyor belts 34 are built in the material guiding shells 31 and arranged along the surface of the material guiding shells 31. The plurality of clamping parts 33 are arranged on the surface of the circulating conveyor belts 34 for circulatingly conveying the material along the surface of the material guiding shells 31, and the two opposite clamping parts 33 cooperate with each other to clamp the material.

[0050] The plurality of clamping parts 33 are arranged on the surface of the circulating conveyor belts 34, so that the clamping parts 33 can circulate along the surface of the material guiding shells 31, thereby forming clamping on the material, enabling the material to better enter the material guiding gap 32 and be cut or chopped by the cutting component 4, and improving the harvesting efficiency.

[0051] In one of the embodiments, please refer to Figure 3 , the clamping part 33 includes a connecting block 331 and two clamping blocks 332. The plurality of connecting blocks 331 are arranged at intervals and are all connected to the belt of the circulating conveyor belt 34. The two clamping blocks 332 are arranged at intervals and are both connected to the connecting block 331. A first clamping half groove is formed by surrounding between the two clamping blocks 332 and the connecting block 331. The two opposite first clamping half grooves surround to form a clamping groove for clamping the material.

[0052] The two opposite clamping parts 33 are respectively arranged on the belts of the two opposite circulating conveyor belts 34. As the circulating conveyor belts 34 run, the two clamping parts 33 can move synchronously and use the first clamping half grooves formed on the two clamping parts 33 to clamp the material.

[0053] Furthermore, the material in the clamping groove can enter the material guide gap 32 at an accelerated speed along with the movement of the circulating conveyor belt 34 and come into contact with the cutting assembly 4, thereby increasing the success rate of harvesting or chopping, thereby improving the efficiency of automatic harvesting.

[0054] Furthermore, the circulating conveyor belt 34 here is a belt conveyor device that is common and easy to purchase on the market. It is a conventional setting well known to those skilled in the art and will not be described in detail.

[0055] In this embodiment, Figure 1 、 Figure 5 As shown, the cutting assembly 4 includes a rotating shaft 41 , a first cutting blade 42 and a driving motor 43 , a connecting plate 44 , and a second cutting blade 45 .

[0056] Among them, the rotating shaft 41 is arranged in a direction perpendicular to the material guide shell 31 and rotates inside the material guide gap 32. The first cutting knife 42 is fixedly sleeved on the rotating shaft 41. The fixed end of the driving motor 43 is connected to the bracket 11 and the output shaft is connected to the rotating shaft 41, which is used to drive the first cutting knife 42 to rotate around the axis of the rotating shaft 41 and cut the material in the material guide gap 32.

[0057] The rotation axis 41 of the rotation axis 41 is perpendicular to the material guiding gap 32 , so that the material is cut into pieces after being conveyed.

[0058] Furthermore, the first cutting blade 42 and the second cutting blade 45 here are both common and easy-to-purchase equipment on the market, and the drive motor 43 is a common and easy-to-purchase drive device on the market. The first cutting blade 42, the second cutting blade 45 and the drive motor 43 here are all conventional settings known to those skilled in the art and will not be described in detail.

[0059] In one embodiment, as shown in the figure, the connecting plate 44 spans the communication gap and is connected to the bracket 11. The connecting plate 44 is provided with a rotation hole, and the rotation shaft 41 is rotatably connected to the rotation hole.

[0060] The connecting plate 44 is used to realize the rotation connection between the rotating shaft 41 and the bracket 11 .

[0061] In one implementation, Figure 5 As shown, the second cutting blade 45 is spaced apart from the first cutting blade and is fixedly sleeved on the rotating shaft 41 , and the second cutting blade 45 is arranged below the bottom plane of the bracket 11 .

[0062] The second cutting blade 45 is spaced apart from the first cutting blade so that the material is cut into three sections when it contacts the first cutting blade and the second cutting blade 45. The second cutting blade 45 is set below the bottom plane of the bracket 11, which can prevent the cut material from being higher than the bracket 11 and blocking the normal travel of the mobile cart 1.

[0063] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0064] A collection box 2 is provided on the mobile trolley 1, and two material guide shells 31 are provided on the mobile trolley 1 at intervals from the collection box. One end of the material guide shell 31 protrudes from the front end of the mobile trolley 1, and the other end extends in a direction close to the collection box 2. A material guide gap 32 is formed between the two material guide shells 31 for guiding materials into the material guide gap 32. A cutting assembly 4 is also provided on the extension path of the material guide gap 32 for cutting the materials entering the material guide gap 32 and dropping them into the collection box 2 for collection. Compared with the prior art, by providing the material guide shell 31 and the collection box 2 on the mobile trolley 1, and further providing the cutting assembly 4 on the extension path of the material guide gap 32, the materials can be guided into the material guide gap 32 as the trolley moves. The materials entering the material guide gap 32 can be automatically cut or chopped by the cutting assembly 4 after moving relative to the mobile trolley 1, and thus collected by the collection box 2, which is convenient to operate.

[0065] The specific working process of the present invention is that the user first moves or pushes the mobile cart 1 to the field where tobacco leaves are planted, and then moves the two mobile wheels 12 of the mobile cart 1 along the planting direction of tobacco leaves. As the two guide shells 31 continuously guide the material into the guide gap 32, the two relative clamping parts 33 realize the clamping of the material, and accelerate the material to the first cutting blade and the second cutting blade 45 under the action of the circulating conveyor belt 34. Finally, the driving motor 43 drives the first cutting blade and the second cutting blade 45 to rotate to harvest or cut the material. The cut material is poured into the collection box 2 by gravity and collected centrally.

[0066] Furthermore, the user continuously pushes the mobile cart 1 to move along the planting direction of tobacco leaves, and can complete the harvesting of flue-cured tobacco with stems, which is convenient for the user to operate, effectively improves the harvesting efficiency, and reduces the intensity of manual labor.

[0067] Through the above structure, this device can solve the problem in the prior art that it is inconvenient to operate because it is necessary to control the movement of the harvesting device and at the same time pull the push-pull rod of the scissor assembly at intervals to drive the knife body to cut the tobacco leaves with stems to complete the harvest.

[0068] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
