Description

Technical Field

[0001] This utility model relates to the field of stem and leaf crushing technology, and in particular to a device for crushing and returning the stems and leaves of ginseng to the field. Background Technology

[0002] As a specialty crop with both medicinal and edible value, ginseng is usually grown using a raised bed cultivation method. In actual planting, the height of the raised bed will vary dynamically depending on factors such as the planting area and growth cycle. Furthermore, the stems and leaves of ginseng are fleshy and have high water content. After harvesting, the stems, leaves, and root stubble remaining on the surface of the raised bed and in the shallow soil layer need to be crushed and returned to the field to achieve nutrient recycling. This is a key step in ensuring soil fertility for ginseng cultivation. A search revealed a Chinese patent with publication number CN205408577U, which provides a crop root, stem, and leaf pulverizer and returning machine. Primarily designed for flat or conventional ridge crops, it is equipped with a root removal device, a stubble-collecting device, and a stem and leaf pulverizer, enabling the cutting, collection, and pulverization of corn stalks. However, during use, it was found that the operating height of the root removal and stem and leaf pulverizer components is relatively fixed, making it difficult to adapt to the varying ridge heights of ginseng fields. This easily leads to problems such as missed cutting of stems and leaves at higher ridges and excessive cutting of root stubble at lower ridges, damaging the soil structure. It is difficult to ensure comprehensive pulverization and returning of ginseng stems and leaves to the field, and it can also adversely affect the soil environment for subsequent ginseng planting, thus hindering the effective use of ginseng stem and leaf pulverization for returning to the field. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a device for crushing and returning the stems and leaves of ginseng to the field, which improves the comprehensiveness of crushing and returning to the field, provides a foundation for subsequent nutrient recycling, and meets the crushing and returning needs of ginseng planting plots.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for crushing and returning ginseng stems and leaves to the field, comprising a shell, a stubble-cutting assembly provided at one end of the shell, the stubble-cutting assembly comprising a rotating shaft, two fixed blocks fixedly connected to both ends of the rotating shaft, multiple adjusting blocks inserted into the fixed blocks, a stubble-cutting blade installed at the outer end of the adjusting blocks, multiple electric push rods installed on the fixed blocks, piston rods on the electric push rods fixedly connected to the outer end of the adjusting blocks, and two anti-tangling nets provided on the outer side of the rotating shaft, the anti-tangling nets being fixedly connected to the fixed blocks; A limiting groove is provided at one end of the housing. The outer peripheral wall of the rotating shaft is slidably connected to the groove wall of the limiting groove. Two movable blocks are rotatably connected to both ends of the rotating shaft. The inner wall of the movable block is slidably connected to the outer wall of the housing. A first servo motor is installed on one of the movable blocks. The piston rod of the first servo motor is coaxially connected to the rotating shaft.

[0005] Preferably, two cylinders are fixedly connected to the outer wall of the housing, the bottom surface of the piston rod of the cylinder is fixedly connected to the top surface of the movable block, and the plurality of adjusting blocks are slidably connected to the fixed block respectively.

[0006] Through the above technical solution, the piston rod of the cylinder extends and retracts, causing the movable block to slide along the outer wall of the housing. The sliding fit of the limiting groove enables the adjustment of the overall working height of the rotating shaft and the cutting blade.

[0007] Preferably, a splash guard is fixedly connected to one end of the adjusting block near the cutting blade, and the splash guard is slidably connected to the fixed block.

[0008] Through the above technical solution, the splash guard slides synchronously with the adjusting block, reducing the impact of debris on the electric push rod during the cutting process.

[0010] Preferably, a second servo motor is installed on the outer wall of the protective cover, and the output shaft of the second servo motor is coaxially connected to the feeding roller, with a gap between the feeding roller and the cutting blade.

[0011] Through the above technical solution, the output shaft of the second servo motor drives the feeding roller to rotate. The feeding roller, through the gap between itself and the cutting blade, feeds the red ginseng stems and leaves on the surface of the ridge and the surrounding area toward the cutting blade, reducing the scattering and missed cutting of stems and leaves.

[0018] Through the above technical solution, the chopped stems and leaves are guided into the crushing component inside the shell by the first and second guide blocks. The bottom surface of the second guide block is inclined, which reduces the adhesion and residue of debris on the bottom surface of the second guide block.

[0019] The beneficial effects of this utility model are as follows: The output shaft of the first servo motor drives the coaxially connected rotating shaft to rotate, and the fixed blocks at both ends of the rotating shaft rotate synchronously, thereby driving the adjustment block inserted on the fixed block and the stubble cutter installed on the outer end to rotate, forming a cutting action to cut the stubble; By controlling the movable block on the outer wall of the shell to slide along the outer wall of the shell, and in conjunction with the sliding cooperation between the outer peripheral wall of the rotating shaft and the upper limit groove of the shell, the overall working height of the rotating shaft and the stubble cutter can be adjusted, making it easy to adjust to a suitable stubble retention and crushing height; The piston rod of the electric push rod extends and retracts, pushing the adjustment block to slide along the fixed block, thereby adjusting the extension length of the stubble cutter to adapt to different ridge heights for cutting the stems and leaves of ginseng; The stubble cutter can easily cover the stems, leaves, and root stubble on the surface of the ridge and the shallow soil layer, improving the comprehensiveness of crushing and returning to the field, providing a foundation for subsequent nutrient recycling, and meeting the crushing and returning to the field requirements of ginseng planting plots.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figures 1-5 As shown, this embodiment provides a device for crushing and returning ginseng stems and leaves to the field, including a shell 100. One end of the shell 100 is provided with a stubble-cutting assembly 200. The stubble-cutting assembly 200 includes a rotating shaft 201. Two fixing blocks 202 are fixedly connected to both ends of the rotating shaft 201. Multiple adjusting blocks 203 are inserted into the fixing blocks 202. A stubble-cutting blade 204 is installed on the outer end of the adjusting blocks 203. Multiple electric push rods 205 are installed on the fixing blocks 202. The piston rods on the electric push rods 205 are fixedly connected to the outer end of the adjusting blocks 203. Two anti-tangling nets 206 are provided on the outer side of the rotating shaft 201. The anti-tangling nets 206 are fixedly connected to the fixing blocks 202. A limiting groove 207 is provided at one end of the housing 100. The outer peripheral wall of the rotating shaft 201 is slidably connected to the groove wall of the limiting groove 207. Two movable blocks 208 are rotatably connected to both ends of the rotating shaft 201. The inner wall of the movable block 208 is slidably connected to the outer wall of the housing 100. A first servo motor 209 is installed on one of the movable blocks 208. The piston rod of the first servo motor 209 is coaxially connected to the rotating shaft 201.

[0024] Two cylinders 210 are fixedly connected to the outer wall of the housing 100. The bottom surface of the piston rod of the cylinder 210 is fixedly connected to the top surface of the movable block 208. Multiple adjusting blocks 203 are slidably connected to the fixed block 202 respectively. The piston rod of the cylinder 210 extends and retracts, causing the movable block 208 to slide along the outer wall of the housing 100. The sliding engagement of the limiting groove 207 realizes the adjustment of the overall working height of the rotating shaft 201 and the cutting blade 204.

[0025] An anti-splash shell 211 is fixedly connected to one end of the adjusting block 203 near the cutting blade 204. The anti-splash shell 211 is slidably connected to the fixed block 202. The anti-splash shell 211 slides synchronously with the adjusting block 203, reducing the impact of debris on the electric push rod 205 during the cutting process.

[0026] Multiple electric drive wheels 101 are installed on the lower outer wall of the housing 100. A protective cover 102 is fixedly connected to the upper side of one side of the housing 100. A feeding roller 103 is provided inside the protective cover 102. The two ends of the feeding roller 103 are rotatably connected to the protective cover 102. A second servo motor 104 is installed on the outer wall of the protective cover 102. The output shaft of the second servo motor 104 is coaxially connected to the feeding roller 103. A gap is left between the feeding roller 103 and the stubble cutter 204. The output shaft of the second servo motor 104 drives the feeding roller 103 to rotate. The feeding roller 103, through the gap between itself and the stubble cutter 204, feeds the red ginseng stems and leaves on the surface of the ridge and the surrounding area toward the stubble cutter 204, reducing the scattering and missed cutting of stems and leaves.

[0027] A crushing assembly 300 is provided at one end of the housing 100 away from the rotating shaft 201. The crushing assembly 300 includes two crushing rollers 301. The outer peripheral walls at both ends of the central shaft of the crushing rollers 301 are rotatably connected to the housing 100. The crushing rollers 301 are inclined. The central shaft of the crushing rollers 301 is not perpendicular to the housing 100, which makes the crushing of the red ginseng stems and leaves by the rotating crushing rollers 301 more fine. At the same time, it reduces the straight passage of stems and leaves through the crushing gap, reduces long strips of residue, and makes the crushed particles more uniform, which meets the requirements of returning the red ginseng stems and leaves to the field after rapid decomposition.

[0028] One end of the central shaft of the crushing roller 301 extends through the housing 100 to the outside. A gear 302 is sleeved on the central shaft of the crushing roller 301 extending to the outside. The two gears 302 mesh with each other. A sealing box 303 is fixedly connected to the outer wall of the housing 100. The two gears 302 are located inside the sealing box 303. A third servo motor 304 is installed on the outer wall of the sealing box 303. The output shaft of the third servo motor 304 is coaxially connected to the central shaft of one of the crushing rollers 301. The output shaft of the third servo motor 304 drives the coaxially connected crushing roller 301 to rotate. The gear 302 on the central shaft of the crushing roller 301 meshes with the gear 302 of the other crushing roller 301, thereby driving the two crushing rollers 301 to rotate synchronously in opposite directions to crush the introduced stems and leaves.

[0029] The housing 100 is fixedly connected with a first guide block 400 and a second guide block 500. There is a gap between the first guide block 400 and the cutting blade 204. The first guide block 400 is adapted to one of the crushing rollers 301. After being cut, the stems and leaves enter the crushing component 300 inside the housing 100 through the guiding action of the first guide block 400 and the second guide block 500. The bottom surface of the second guide block 500 is inclined, which reduces the adhesion and residue of debris on the bottom surface of the second guide block 500.

[0030] Working principle: The output shaft of the first servo motor 209 drives the coaxially connected rotating shaft 201 to rotate. The fixed blocks 202 at both ends of the rotating shaft 201 rotate synchronously, thereby driving the adjustment block 203 inserted on the fixed block 202 and the shaving blade 204 installed on the outer end to rotate, forming a cutting action to cut stubble; by controlling the movable block 208 on the outer wall of the housing 100 to slide along the outer wall of the housing 100, and cooperating with the sliding fit between the outer peripheral wall of the rotating shaft 201 and the upper limit groove 207 of the housing 100, the overall working height of the rotating shaft 201 and the shaving blade 204 can be adjusted to a suitable stubble retention and crushing height; The piston rod of the electric actuator 205 extends and retracts, pushing the adjusting block 203 to slide along the fixed block 202, thereby adjusting the extension length of the stubble cutter 204 to adapt to different ridge heights and cut the stems and leaves of the ginseng. The stubble cutter 204 can easily cover the stems, leaves, and root stubble on the ridge surface and in the shallow soil layer, improving the comprehensiveness of crushing and returning to the field, providing a foundation for subsequent nutrient recycling, and meeting the crushing and returning to the field requirements of ginseng planting plots. The anti-tangling net 206 moves synchronously with the fixing block 202, reducing the tangling of stems and leaves on the fixing block 202 during the cutting process, making it easier for the cutting blade 204 to cut the tangled stems and leaves, reducing the work jam caused by tangling, and improving the cutting efficiency and continuity. The piston rod of cylinder 210 extends and retracts, causing the movable block 208 to slide along the outer wall of housing 100. The sliding engagement of the limiting groove 207 enables the adjustment of the overall working height of the rotating shaft 201 and the stubble cutter 204. The electric drive wheel 101 drives the entire device to move along the ridge, coordinating with the progress of the work process. The output shaft of the second servo motor 104 drives the feeding roller 103 to rotate. The feeding roller 103, through the gap between itself and the cutting blade 204, feeds the red ginseng stems and leaves on the surface and surrounding area of ​​the ridge towards the cutting blade 204, reducing the scattering and missed cutting of stems and leaves. The splash guard 211 slides synchronously with the adjusting block 203, reducing the impact of debris on the electric push rod 205 during the cutting process. After being chopped, the stems and leaves are guided by the first guide block 400 and the second guide block 500 into the crushing assembly 300 inside the housing 100. The bottom surface of the second guide block 500 is inclined, which reduces the adhesion and residue of debris on the bottom surface of the second guide block 500. The output shaft of the third servo motor 304 drives the crushing roller 301 connected to it to rotate. The gear 302 on the central shaft of the crushing roller 301 meshes with the gear 302 of the other crushing roller 301, thereby driving the two crushing rollers 301 to rotate synchronously in opposite directions to crush the introduced stems and leaves. The sealing box 303 protects the two gears 302. The central axis of the crushing roller 301 is not perpendicular to the housing 100, which makes the crushing of the red ginseng stems and leaves by the rotating crushing roller 301 more fine. At the same time, it reduces the straight passage of stems and leaves through the crushing gap, reduces long strips of residue, and makes the crushed particles more uniform, thus meeting the requirements of returning the red ginseng stems and leaves to the field after rapid decomposition.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
