[0018] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0019] like Figures 1-6 As shown, a weeding device for scallion cultivation according to an embodiment of the present invention includes: The system includes a 1000-unit frame, a lifting assembly, a 3000-unit weeding assembly, a grass-turning assembly, a 5000-unit guide plate, a 6000-unit soil filter assembly, and a 7000-unit grass collection box. Multiple walking components 1500 are rotatably arranged at the bottom of the placement frame 1000. A placement box 1200 is provided at one end of the top of the placement frame 1000. The inner cavity of the placement box 1200 is divided into a control cavity 1220 and a turning cavity 1230 by a partition plate 1210. A feed inlet 1100 is provided on the placement frame 1000, and the feed inlet 1100 is connected to the turning cavity 1230. The lifting assembly includes a lifting drive, an auxiliary lifting component, and a lifting platform 2300. The lifting drive is located in the control cavity 1220. The lifting drive drives one end of the auxiliary lifting component to move, and the other end of the auxiliary lifting component is equipped with the lifting platform 2300. The weeding component 3000 is mounted on the lifting platform 2300; The grass-turning assembly is set inside the turning chamber 1230. The grass-turning assembly includes a grass-turning rod 4400. The grass-turning rod 4400 is rotatably set above the feed inlet 1100 through the bearing seat 4500. Multiple grass-turning plates 4410 are arranged circumferentially on the grass-turning rod 4400. Multiple guide plates 5000 are symmetrically arranged on both sides of the feed inlet 1100 at the bottom of the placement frame 1000, and the guide plate 5000 is located at one end of the feed inlet 1100 near the weeding component 3000. The soil filter assembly 6000 is disposed between two guide plates 5000 and is located at the other end of the feed inlet 1100. The soil filter assembly 6000 includes a soil shovel 6300, on which multiple soil filter openings 6310 are arranged. When the grass turning rod 4400 rotates, the grass turning plate 4410 rotates within the soil filter openings 6310. The grass collection box 7000 is located at the bottom of the other end of the placement frame 1000, and the grass collection box 7000 is close to the filter soil assembly 6000. The grass collection port is opened at the other end of the placement frame 1000, and the grass collection port is connected to the inner cavity of the grass collection box 7000. The grass collection port is close to the other end of the feed inlet 1100. When using the weeding device for scallion planting according to this invention, the user needs to determine the root depth of the weeds based on their type, and then control the lifting component to lower the weeding component 3000. During use, the weeding component 3000 is activated, and its weeding blade disc 3300 rotates. The user pushes the placement frame 1000 forward on the ridge. The rotation direction of the weeding blade disc 3300 is opposite to the forward direction of the placement frame 1000, causing the placement frame 1000 to weed the ridge during its movement. Soil at a certain depth is shoveled up, bringing out weeds along with it. At this point, the shoveled soil is in a state of separation from the weeds. The placement frame 1000 continues to move forward, and the guide plate 5000 gathers the soil. The soil shovel plate 6300 in the soil filter assembly 6000 shovels up and gathers the soil as the placement frame 1000 moves forward. The soil without weeds will fall back into the ridge through the soil filter port 6310, while the weeds, due to their length and branches, cannot fall through the soil filter port 6310 and will be temporarily left on the soil shovel plate 6300. When the weeding component 3000 is started, the grass-turning component starts simultaneously. The grass-turning component drives the grass-turning rod 4400 to rotate, and the grass-turning rod 4400 drives the grass-turning plate 4410 to rotate simultaneously. The direction of rotation of the grass-turning rod 4400 is the same as the direction of rotation of the weeding blade 3300. During the rotation of the grass-turning plate 4410, the grass-turning plate 4410 will rotate a certain distance within the soil filter port 6310. At this time, the grass-turning plate 4410 will drive the weeds on the soil scraper plate 6300 to move to the other end of the feed port 1100 and bring the weeds out of the feed port 1100, so that the weeds fall into the grass collection box 7000 connected to the grass collection port, thereby completing the weed collection work. During the rotation of the grass-turning plate 4410, the grass-turning plate 4410 further turns the soil on the soil scraper plate 6300, accelerates the separation of soil and weeds, and speeds up the weed collection time.

[0020] Furthermore, the walking component 1500 uses wheels to facilitate the movement of the placement frame 1000.

[0021] Furthermore, such as Figure 4 As shown, a sliding groove 1240 is provided on one side wall of the carriage 1200. The auxiliary lifting components include multiple lifting frames 2210 and a support plate 2220. The other end of the lifting frame 2210 passes through the sliding groove 1240 and extends into the control cavity 1220. One end of the multiple lifting frames 2210 is symmetrically arranged on the lifting platform 2300. The support plate 2220 is arranged at the other end of two lifting frames 2210. A lifting threaded hole is provided at the center of the support plate 2220.

[0022] Furthermore, such as Figure 4 and Figure 5As shown, the lifting drive includes a lifting motor 2110, a lead screw rotator 2120, and a lifting lead screw 2130. The lifting motor 2110 and the lead screw rotator 2120 are both located in the control cavity 1220. The output end of the lifting motor 2110 is connected to the input end of the lead screw rotator 2120. The lifting lead screw 2130 is located at the output end of the lead screw rotator 2120. The lifting lead screw 2130 is threadedly engaged with the lifting threaded hole of the bearing plate 2220.

[0023] The specific working principle of the lifting assembly: When the lifting motor 2110 starts, the output end of the lifting motor 2110 drives the input end of the lead screw 2120 to rotate, which in turn drives the lifting lead screw 2130 to rotate. Because the lifting threaded hole of the bearing plate 2220 is threadedly engaged with the lifting lead screw 2130, when the lifting lead screw 2130 rotates forward, the bearing plate 2220 moves upward. The bearing plate 2220 synchronously drives the lifting platform 2300 to rise through the lifting frame 2210. When the lifting lead screw 2130 rotates in reverse, the bearing plate 2220 moves downward, and the lifting platform 2300 descends synchronously. The lifting frame 2210 cooperates with the sliding groove 1240 to ensure the stability of the lifting frame 2210 during the upward and downward movement.

[0024] Preferably, such as Figure 3 , Figure 4 and Figure 5 As shown, the weeding device for scallion planting also includes a guide component 9400, which includes a guide rod 9420 and a guide block 9410. The guide blocks 9410 are symmetrically arranged on both sides of the support plate 2220. Guide holes 9411 are formed on the guide blocks 9410. One end of the guide rod 9420 passes through the guide hole 9411, and the other end of the guide rod 9420 is fixedly mounted at the bottom of the control cavity 1220. When the support plate 2220 rises and falls, the guide blocks 9410 on both sides of the support plate 2220 slide on the guide rod 9420, improving the stability of the support plate 2220 during its rising and falling motion.

[0025] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the weeding assembly 3000 includes a mounting frame 3100, a weeding motor 3200, a weeding disc 3300, and blades 3310. The lifting platform 2300 is provided with mounting frames 3100 on both sides. The weeding disc 3300 is rotatably connected to the mounting frame 3100. Multiple sets of blades 3310 are fixedly connected to the weeding disc 3300 in a circular array. The weeding motor 3200 is fixedly connected to the lifting platform 2300 and is poweredly connected to the weeding disc 3300.

[0026] Furthermore, such as Figure 3 and Figure 4As shown, the output end of the weeding motor 3200 is fixedly connected to the power output shaft 3500. The lifting platform 2300 is symmetrically arranged with first transmission components. The power output shaft 3500 drives the first power output shaft 3410 in the first transmission component through bevel gears. The two ends of the weeding blade disc 3300 are fixedly connected to the second power output shaft 3430. The second power output shaft 3430 is rotatably mounted on the mounting bracket 3100. The first power output shaft 3410 and the second power output shaft 3430 are connected through the chain transmission component 9200.

[0027] Preferably, such as Figure 3 and Figure 4 As shown, the first transmission component includes a first power output shaft 3410 and multiple rotating seats 3420. The first power output shaft 3410 is rotatably mounted on the multiple rotating seats 3420. One end of the first power output shaft 3410 is provided with a bevel gear, and the other end of the power output shaft is also provided with a bevel gear, so that the power output main shaft 3500 drives the first power output shaft 3410 through the bevel gear engagement. The other end of the first power output shaft 3410 is provided with a sprocket, and the second power output shaft 3430 is also provided with a sprocket, so that the sprocket on the first power output shaft 3410 drives the sprocket on the second power output shaft 3430 through a chain, ultimately driving the weeding blade disc 3300 to rotate.

[0028] Furthermore, such as Figure 3 As shown, the grass-turning assembly includes a grass-turning motor 4100, a first grass-turning output shaft 4200, and a second grass-turning output shaft 4300. The grass-turning motor 4100 is located inside the turning chamber 1230 on one side of the isolation plate 1210. The power output end of the grass-turning motor 4100 is fixedly connected to the first grass-turning output shaft 4200. The two ends of the grass-turning rod 4400 are fixedly connected to the second grass-turning output shaft 4300. The second grass-turning output shaft 4300 is rotatably mounted on the bearing seat 4500. The first grass-turning output shaft 4200 and the second grass-turning output shaft 4300 are connected by a chain drive component 9200. The working principle of the grass-turning assembly is as follows: the output end of the grass-turning motor 4100 drives the grass-turning first output shaft 4200 to rotate. The grass-turning first output shaft 4200 is equipped with a sprocket, and the grass-turning second output shaft 4300 at both ends of the grass-turning rod 4400 is also equipped with a sprocket. At this time, by setting a chain, the grass-turning first output shaft 4200 and the grass-turning second output shaft 4300 can achieve chain transmission, thereby driving the grass-turning rod 4400 to rotate.

[0029] Furthermore, such as Figure 4 As shown, the soil filter assembly 6000 includes a mounting plate 6100 and a soil scraper 6300. The mounting plate 6100 contacts the guide plate 5000, and the soil scraper 6300 is inclined between the two mounting plates 6100. The inclined soil scraper 6300 helps to scrape up the soil that has been gathered by the guide plate 5000.

[0030] Preferably, such as Figure 2 As shown, the guide plate 5000 and the mounting plate 6100 are both bolted to the bottom of the placement frame 1000, allowing users to install guide plates 5000, mounting plates 6100 and shovel plates 6300 at different heights according to the rooting depth of the weeds, which facilitates subsequent weeding work.

[0031] Further, as shown in the figure, the bottom of the inner cavity of the grass collection box 7000 is provided with multiple sieve holes 7100, the top of the grass collection box 7000 is provided with a splash guard 7200, the top of the splash guard 7200 is provided with a material intake port, and a box cover 7300 is rotatably provided on the material intake port. The other side of the placement box 1200 is provided with a material passage port 1250, and the turning chamber 1230 is connected to the inner cavity of the splash guard 7200 and the inner cavity of the grass collection box 7000 through the material passage port 1250. After the weeds are brought out of the shovel plate 6300 by the turning board 4410, they enter the collection port through the feed inlet 1250 and finally fall into the collection box 7000. The roots of the weeds usually have loose soil attached. When the weeds fall into the collection box 7000, the loose soil is loosened and detached from the roots of the weeds due to the collision. At this time, the bottom of the collection box 7000 is equipped with multiple sieve holes 7100. The soil falls into the surface of the ridge through the sieve holes 7100. At the same time, the diameter of the sieve holes 7100 is smaller than the size of the weeds, so the weeds will not fall through the sieve holes 7100. At the same time, a splash guard 7200 is set to prevent the soil from being thrown backward when the turning rod 4400 rotates. The user controls the movement of the placement frame 1000 using the handle 1300, and the box cover 7300 makes it easy for personnel to take out the weeds collected in the collection box 7000.

[0032] Preferably, the soil attached to the turning straw 4400 or the soil brought into the straw collection box 7000 by turning is discharged through the sieve hole 7100.

[0033] Furthermore, such as Figure 3 As shown, a battery pack 9300 is installed inside the control cavity 1220, and a handle 1300 is installed at the other end of the vehicle frame 1000. The handle 1300 is located on one side of the splash guard 7200, away from the vehicle frame 1200. The battery pack 9300 supplies power to the lifting motor 2110, the weeding motor 3200, and the weeding motor 4100, ensuring the normal operation of the lifting assembly, the weeding assembly 3000, and the weeding assembly.

[0034] Furthermore, such as Figure 3 , Figure 4 and Figure 5As shown, the weeding device for scallion planting also includes a limiting component 8000, which includes an electric push rod 8100, a push block 8200, and a sliding block 8300. A limiting groove 1400 is opened at the bottom of the placement frame 1000. The limiting groove 1400 is symmetrically arranged on both sides of the lifting motor 2110. The limiting groove 1400 is connected to the control cavity 1220. The push block 8200 and the sliding block 8300 both slide in the limiting groove 1400. The push block 8200 is fixed to the sliding block 8300 by bolts. The electric push rod 8100 is located at the bottom of the control cavity 1220. The output end of the electric push rod 8100 is connected to the push block 8200. As shown in the figure, when the push block 8200 is T-shaped, it will be stuck on the limit slide groove 1400 of the control cavity 1220. During installation, the push block 8200 needs to be installed first, and then the sliding block 8300 needs to be installed with bolts. Working principle of the limiting component: When this utility model is in a non-working state, the electric push rod 8100 is in the extended state, causing the push block 8200 to move towards the weeding component 3000, so that one end of the sliding block 8300 protrudes from the frame 1000. At this time, the lifting platform 2300 in the lifting component contacts one end of the sliding block 8300 and lifts the lifting platform 2300, thereby sharing the weight of the lifting platform 2300 and the weeding component 3000 and preventing the lifting platform 2300 and the weeding component 3000 from collapsing. All the weight is concentrated on the lifting screw 2130, thereby increasing the service life of the lifting screw 2130, avoiding frequent maintenance by personnel, and saving labor intensity. When this utility model is in working state, the lifting component is raised to the highest position, the electric push rod 8100 is controlled to retract, the push block 8200 moves closer to the electric push rod 8100, and one end of the sliding block 8300 will retract into the limiting slide groove 1400 where the frame 1000 is placed. After the sliding block 8300 is fully retracted, the lifting component is controlled to the set height.

[0035] Preferably, both the isolation plate 1210 and the vehicle box 1200 are provided with wiring holes, and the wires are electrically connected to the lifting motor 2110 and the weeding motor 3200 and the battery pack 9300 through the wiring holes.

[0036] Preferably, such as Figure 2 and Figure 4 As shown, the weeding device for scallion cultivation also includes soil dividers 9100, with multiple soil dividers 9100 arranged near the bottom of the grass collection box 7000 close to the soil scraper plate 6300. Soil falling from the soil scraper plate 6300 through the soil filter port 6310 will accumulate, and at this time, the multiple soil dividers 9100 will level the accumulated soil.
