Description
Technical Field
[0001] This utility model belongs to the field of agricultural weeding technology, and in particular relates to an agricultural weeding device for agricultural facilities. Background Technology
[0002] With the continuous development of society, the level of agricultural production is also constantly improving. Among them, weeds are an important factor affecting land yield in agricultural production. Therefore, in the process of agricultural planting, it is necessary to use agricultural facilities and weeding devices to remove weeds in farmland to prevent weeds from affecting the production of crops.
[0003] However, existing agricultural weeding devices inevitably come into contact with hard materials such as stones when cutting weeds. If the blades cannot avoid these materials in time, the cutting blades or the machine may be damaged, increasing maintenance costs and potentially reducing the efficiency of crop management due to equipment failure. Utility Model Content
[0004] The purpose of this utility model is to provide an agricultural weeding device for agricultural facilities. By setting up a cutting mechanism, when it collides with obstacles such as stones and branches, the cutting blade can swing back to avoid them as the centrifugal force disappears or the reverse force is reversed, thus avoiding hard damage to the cutting blade or the machine. This solves the problem that existing agricultural weeding devices inevitably collide with hard materials such as stones when cutting weeds, and if the blade cannot avoid them in time, it is easy to cause hard damage to the cutting blade or the machine.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is an agricultural weeding device for agricultural facilities, including a movable plate, a cutting mechanism and an adjustment mechanism;
[0007] The cutting mechanism includes a cutting component and a driving component. The cutting component is disposed at the bottom of the moving plate, and the driving component is disposed at the top of the moving plate.
[0008] The cutting assembly includes a housing, with a plurality of connecting shafts fixedly connected to the inner wall of the housing, cutting blades rotatably connected to the outer walls of the plurality of connecting shafts, hinge blocks I rotatably connected to the bottom surfaces of the plurality of cutting blades, and a plurality of hinge blocks II rotatably connected to the inner wall of the fixing ring, with springs fixedly connected between the plurality of hinge blocks I and the plurality of hinge blocks II respectively.
[0009] The adjustment mechanism includes a connecting frame, the movable plate is slidably connected to the inner wall of the connecting frame, rollers are rotatably connected to the front and rear sides of the connecting frame, and handles are fixedly connected to the front and rear sides of the connecting frame.
[0010] Furthermore, the drive assembly includes a housing fixedly connected to the top surface of the movable plate, and a motor is fixedly connected to the inner wall of the housing.
[0011] Furthermore, the output end of the motor is fixedly connected to a rotating shaft via a coupling. The bottom end of the rotating shaft extends to the bottom of the moving plate. The rotating shaft is rotatably connected to the moving plate. Several protrusions are fixedly connected to the outer wall of the rotating shaft, and baffles are fixedly connected to the outer walls of the several protrusions.
[0012] Furthermore, the outer walls of several of the protrusions are slidably connected to the inner wall of the fixing ring, the top surface of the fixing ring is in contact with the bottom surface of the first baffle, the bottom end of the rotating shaft is fixedly connected to a connecting rod, and the outer wall of the connecting rod is fitted with a second baffle.
[0013] Furthermore, the bottom end of the rotating shaft is fixedly connected to several threaded rods, each of which passes through a baffle plate. Nuts are threadedly connected to the outer walls of the baffle plates, and each of the nuts is connected to the bottom surface of the baffle plate.
[0014] Furthermore, a threaded rod 2 is rotatably connected to the inner bottom wall of the connecting frame. The top end of the threaded rod 2 extends to the top of the connecting frame. The threaded rod 2 passes through the movable plate and is threadedly connected to the movable plate. Two sliding rods are fixedly connected to the inner wall of the connecting frame.

[0015] Furthermore, a knob is fixedly connected to the top end of the threaded rod two, and an arc-shaped baffle is fixedly connected to the bottom surface of the movable plate.
[0016] This utility model has the following beneficial effects:
[0017] 1. By incorporating a cutting mechanism, the cutting blade stretches the spring during its unfolding process, causing the spring to deform. When it collides with obstacles such as rocks or branches, the cutting blade can swing back to avoid them as the centrifugal force dissipates or the reverse force reverses, preventing hard damage to the cutting blade or the machine. This "flexible cutting" characteristic extends the blade's lifespan and reduces maintenance costs. It is especially suitable for weeding operations in complex terrains such as orchards and mountainous areas. At the same time, it avoids the cutting blade being exposed when not in use, significantly reducing the risk of accidental contact. It is particularly suitable for lawn mowing equipment used in public places or homes, improving operational safety.
[0018] 2. With an adjustable mechanism, the connecting frame can be pushed by hand, moving it to cut grass with the help of rollers. The angle of the fixed ring can be adjusted according to the actual situation, and the screw rod can be rotated by turning the knob, which in turn moves the moving plate up or down with the slide rod, adjusting the height of the cutting component. This greatly improves the practicality of the overall device and makes it simple and convenient to operate.

[0030] Please see Figure 1-6 As shown, this utility model is an agricultural weeding device for agricultural facilities, including a movable plate 1, a cutting mechanism 2, and an adjusting mechanism 3;
[0031] The cutting mechanism 2 includes a cutting component 21 and a driving component 22. The cutting component 21 is disposed at the bottom of the moving plate 1, and the driving component 22 is disposed at the top of the moving plate 1.
[0032] The cutting assembly 21 includes a housing 221. A plurality of connecting shafts 212 are fixedly connected to the inner wall of the housing 221. Cutting blades 213 are rotatably connected to the outer walls of each of the connecting shafts 212. Hinge blocks 214 are rotatably connected to the bottom surfaces of each of the cutting blades 213. A plurality of hinge blocks 215 are rotatably connected to the inner wall of the fixing ring 211. Springs 216 are fixedly connected between each of the hinge blocks 214 and hinge blocks 215. The driving assembly 22 includes the housing 221 fixedly connected to the top surface of the moving plate 1. The inner wall of the housing 221 is fixedly connected to... A motor 222 is connected, and the output end of the motor 222 is fixedly connected to a rotating shaft 223 via a coupling. The bottom end of the rotating shaft 223 extends to the bottom of the movable plate 1, and the rotating shaft 223 is rotatably connected to the movable plate 1. Several protrusions 224 are fixedly connected to the outer wall of the rotating shaft 223, and baffles 225 are fixedly connected to the outer wall of the protrusions 224. The outer wall of the protrusions 224 is slidably connected to the inner wall of the fixing ring 211, and the top surface of the fixing ring 211 contacts the bottom surface of the baffle 225. A connecting rod 226 is fixedly connected to the bottom end of the rotating shaft 223, and the outer wall of the connecting rod 226... A second baffle plate 228 is fitted onto the shaft 223. Several threaded rods 227 are fixedly connected to the bottom end of the shaft 223, all of which pass through the second baffle plate 228. Nuts 229 are threaded onto the outer walls of each baffle plate 228, and each nut 229 contacts the bottom surface of the baffle plate 228. A cutting mechanism 2 is provided, causing the cutting blade 213 on the connecting shaft 212 to expand outwards under centrifugal force, maintaining blade stability and cutting efficiency. At this time, multiple hinge blocks 214 and hinge blocks 215 cooperate with each other, allowing the cutting blade... During the unfolding process, the blade 213 stretches the spring 216, causing the spring 216 to deform. When it collides with obstacles such as rocks and branches, the cutting blade 213 can swing back to avoid them as the centrifugal force disappears or the reverse force is applied, thus avoiding hard damage to the cutting blade 213 or the machine. This "flexible cutting" characteristic extends the blade's life and reduces maintenance costs. It is especially suitable for weeding operations in complex terrains such as orchards and mountains. At the same time, it avoids the exposure of the cutting blade 213 when it is not in operation, significantly reducing the risk of accidental contact. It is especially suitable for lawn mowing equipment used in public places or homes, improving operational safety.
[0033] The adjusting mechanism 3 includes a connecting frame 31, a movable plate 1 slidably connected to the inner wall of the connecting frame 31, rollers 5 rotatably connected to the front and rear sides of the connecting frame 31, handles 4 fixedly connected to the front and rear sides of the connecting frame 31, a threaded rod 33 rotatably connected to the inner bottom wall of the connecting frame 31, the top end of the threaded rod 33 extending to the top of the connecting frame 31, the threaded rod 33 passing through the movable plate 1, and the threaded rod 33 threadedly connected to the movable plate 1, and two sliding rods 32 fixedly connected to the inner wall of the connecting frame 31. The moving plate 1 is slidably connected to two sliding rods 32. A knob 34 is fixedly connected to the top of the threaded rod 33. An arc-shaped baffle 35 is fixedly connected to the bottom surface of the moving plate 1. By setting an adjustment mechanism 3, the angle of the fixed ring 211 can be adjusted according to the actual situation. The knob 34 can be turned to drive the threaded rod 33 to rotate, which, together with the sliding rod 32, drives the moving plate 1 to rise or fall, thereby adjusting the height of the cutting component 21. This greatly improves the practicality of the overall device and makes it simple and convenient to operate.
[0034] A specific application of this embodiment is as follows: By setting up a cutting mechanism 2, when the drive motor 222 drives the rotating shaft 223 to rotate, the cutting assembly 21 rotates synchronously with the rotating shaft 223 under the cooperation of multiple protrusions 224. The fixing ring 211 drives multiple connecting shafts 212 to rotate, causing the cutting blade 213 on the connecting shaft 212 to spread outward under the action of centrifugal force, maintaining the stability of the blade and cutting efficiency. At this time, multiple hinge blocks 1 214 and hinge blocks 215 cooperate with each other, so that the cutting blade 213 stretches the spring 216 during the unfolding process, causing the spring 216 to deform. When colliding with obstacles such as stones and branches, the cutting blade 213 can be released with the disappearance of centrifugal force or the reverse force. The swing-back avoidance mechanism prevents hard damage to the cutting blade 213 or the machine. This "flexible cutting" feature extends the blade's life and reduces maintenance costs. It is especially suitable for weeding operations in complex terrains such as orchards and mountains. At the same time, it avoids the exposure of the cutting blade 213 when it is not in operation, which significantly reduces the risk of accidental contact. It is especially suitable for lawn mowing equipment used in public places or homes, improving operational safety. When disassembling and assembling the cutting component 21, multiple nuts 229 can be turned to fix the retaining ring 211 between the second baffle 228 and the first baffle 225. The retaining ring 211 is firmly locked with the connecting rod 226 and the threaded rod 227 to prevent it from loosening during the cutting process.
[0035] With the adjustment mechanism 3, during the use of this device, the handle 4 can be held by hand to push the connecting frame 31, which moves with the help of the rollers 5. The angle of the fixed ring 211 can be adjusted according to the actual situation. The knob 34 can be turned to drive the threaded rod 33 to rotate, which, together with the slide rod 32, drives the moving plate 1 to rise or fall, thereby adjusting the height of the cutting component 21. This greatly improves the practicality of the overall device and makes it simple and convenient to operate.
