Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to an adjustable weeding device. Background Technology

[0002] Weeding refers to a method or behavior of removing or controlling weeds. As an important agricultural management practice, weeding has multiple functions. Weeding helps to increase crop yields. Weeds compete with crops for resources such as soil nutrients, water, and light, which restricts crop growth. By weeding, the competition between weeds and crops can be reduced, allowing crops to make better use of these resources.

[0003] Patent publication number CN214960905U discloses a weeding device with adjustable weeding depth, which includes a main body, a rotary tiller, a moving device, and an adjustment device. The rotary tiller is fixedly installed at the lower outer end of the main body, the moving device is fixedly installed at the lower left side of the main body, and a push handle is fixedly installed at the upper left side of the main body. The adjustment device is fixedly installed on the front and rear right sides of the main body. The adjustment device is fixedly connected to the main body and is used to adjust the height of the support frame.

[0004] To address the issue of not being able to adjust the weeding depth, existing technology involves rotating a knob to cause the connecting groove and rotating block to rotate and rise inside the installation groove. Then, the push handle is slowly released, and the height of the main device decreases under the pressure of the device's own weight. However, this method still results in the inability to adjust the spacing of the weeding blades, leading to a problem of not being able to adapt to different planting spacings. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable weeding device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An adjustable weeding device includes a handle, the surface of which is provided with a telescopic mechanism, and the telescopic mechanism is provided with an adjustment mechanism inside.

[0008] The adjustment mechanism includes a first slide rail, which is fixedly installed inside the telescopic mechanism. Two sets of the first slide rail are provided, symmetrically distributed inside the telescopic mechanism. A support frame is movably installed on the surface of the first slide rail, and a motor is fixedly installed on the surface of the support frame. A rotating shaft is fixedly installed at the output end of the motor, and a connecting groove is provided on the surface of the rotating shaft.

[0009] A further improvement of this utility model is that: a vertical rod is movably mounted on the surface of the rotating shaft, and multiple sets of the vertical rod are provided. The vertical rods are evenly distributed on the surface of the rotating shaft, and a cutter head is movably mounted on the surface of the vertical rod.

[0010] A further improvement of this utility model is that: the cutter head is movably mounted on the surface of the rotating shaft, a fixing rod is fixedly installed inside the cutter head, and the surface of the fixing rod is movably mounted on the surface of the connecting groove.

[0011] A further improvement of this utility model is that: a sliding rod is fixedly installed on the surface of the vertical rod, a limiting rod is movably installed on the surface of the vertical rod, and the limiting rod is fixedly installed on the surface of the support frame.

[0012] A further improvement of this utility model is that: an electric telescopic rod is fixedly installed at the bottom of the support frame, a fixed platform is fixedly installed at the telescopic end of the electric telescopic rod, a guide plate is fixedly installed on the surface of the fixed platform, and a sliding groove is provided on the surface of the guide plate, the sliding groove being adapted to the sliding rod.

[0013] A further improvement of the present invention is that the telescopic mechanism includes a housing, the housing is movably mounted on the surface of the handle, a servo motor is fixedly mounted on the surface of the housing, a bidirectional lead screw is fixedly mounted on the output end of the servo motor, and the bidirectional lead screw is movably mounted inside the housing.

[0014] A further improvement of this utility model is that: a slider is threadedly connected to the surface of the bidirectional lead screw, a second slide rail is movably mounted on the surface of the slider, the second slide rail is fixedly mounted inside the housing, a connecting rod is movably mounted on the surface of the slider, a connecting seat is fixedly mounted at one end of the connecting rod, and the connecting seat is fixedly mounted on the top of the support frame.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides an adjustable weeding device, which employs a motor, rotating shaft, cutter disc, vertical rod, sliding rod, limiting rod, guide plate, sliding groove, support frame, electric telescopic rod, first slide rail, fixed platform, fixed rod, and connecting groove. The motor drives the rotating shaft to rotate, and the cutter disc on the surface of the vertical rod passes through the connecting groove on the surface of the rotating shaft through the internal fixed rod, so that the cutter disc rotates with the rotating shaft. When it is necessary to adjust the spacing of the cutter discs, the electric telescopic rod on the surface of the support frame pulls the fixed platform, and the guide plate moves upward. At this time, the sliding rod slides on the surface of the sliding groove, causing multiple sets of vertical rods to slide on the surface of the limiting rod and retract inward, thereby driving the cutter disc to adjust the weeding spacing to adapt to different field needs and improve the adaptability of the device.

[0017] 2. This utility model provides an adjustable weeding device, which uses a housing, servo motor, bidirectional lead screw, slider, connecting rod, connecting seat, and second slide rail. The housing protects the adjustment mechanism. When the weeding depth needs to be adjusted, the servo motor drives the bidirectional lead screw to rotate, causing the slider on the surface of the bidirectional lead screw to move closer to the center along the second slide rail. The slider pushes the connecting seat on the surface of the connecting rod, causing the support frame to slide and move downward on the surface of the first slide rail, thus adjusting the depth of the cutter head into the ground. The tips of the bidirectional lead screw are all wedge-shaped threads with a 30-degree angle, thereby generating a self-locking capability. When the use is finished, the servo motor can also drive the slider to move outward, causing the support frame to rise and retract into the housing, preventing the cutter head from contacting foreign objects and damaging the blades, thus improving the adaptability of the device.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides an adjustable weeding device, including a handle 1. A telescopic mechanism 3 is provided on the surface of the handle 1. An adjustment mechanism 2 is provided inside the telescopic mechanism 3. The adjustment mechanism 2 includes a first slide rail 211, which is fixedly installed inside the telescopic mechanism 3. Two sets of the first slide rails 211 are symmetrically distributed inside the telescopic mechanism 3. A support frame 209 is movably mounted on the surface of the first slide rails 211. A motor 201 is fixedly mounted on the surface of the support frame 209. A rotating shaft 202 is fixedly mounted on the output end of the motor 201. A connecting groove 214 is provided on the surface of the rotating shaft 202. Vertical rods 204 are movably mounted on the surface of the rotating shaft 202. Multiple sets of vertical rods 204 are evenly distributed. A cutter head 203 is movably mounted on the surface of the rotating shaft 202 and the surface of the vertical rod 204. The cutter head 203 is movably mounted on the surface of the rotating shaft 202. A fixing rod 213 is fixedly mounted inside the cutter head 203. The surface of the fixing rod 213 is movably mounted on the surface of the connecting groove 214. A slide rod 205 is fixedly mounted on the surface of the vertical rod 204. A limit rod 206 is movably mounted on the surface of the vertical rod 204. The limit rod 206 is fixedly mounted on the surface of the support frame 209. An electric telescopic rod 210 is fixedly mounted at the bottom end of the support frame 209. A fixed platform 212 is fixedly mounted at the telescopic end of the electric telescopic rod 210. A guide plate 207 is fixedly mounted on the surface of the fixed platform 212. A sliding groove 208 is provided on the surface of the guide plate 207. The sliding groove 208 is adapted to the slide rod 205.

[0027] In this embodiment, the motor 201 drives the rotating shaft 202 to rotate. At this time, the cutter disc 203 on the surface of the vertical rod 204 passes through the connecting groove 214 on the surface of the rotating shaft 202 through the internal fixing rod 213, so that the cutter disc 203 rotates when the rotating shaft 202 rotates. When it is necessary to adjust the spacing of the cutter disc 203, the electric telescopic rod 210 on the surface of the support frame 209 pulls the fixing platform 212, and the guide plate 207 moves upward. At this time, the sliding rod 205 slides on the surface of the sliding groove 208, so that multiple sets of vertical rods 204 slide on the surface of the limiting rod 206 and retract inward, thereby driving the cutter disc 203 to adjust the weeding spacing to adapt to different field needs and improve the adaptability of the device.

[0028] Example 2

[0029] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the telescopic mechanism 3 includes a housing 301, which is movably mounted on the surface of the handle 1. A servo motor 302 is fixedly mounted on the surface of the housing 301. A bidirectional lead screw 303 is fixedly mounted on the output end of the servo motor 302. The bidirectional lead screw 303 is movably mounted inside the housing 301. A slider 304 is threadedly connected to the surface of the bidirectional lead screw 303. A second slide rail 307 is movably mounted on the surface of the slider 304. The second slide rail 307 is fixedly mounted inside the housing 301. A connecting rod 305 is movably mounted on the surface of the slider 304. A connecting seat 306 is fixedly mounted on one end of the connecting rod 305. The connecting seat 306 is fixedly mounted on the top of the support frame 209.

[0030] In this embodiment, the adjustment mechanism 2 is protected by the outer casing 301. When the weeding depth of the adjustment mechanism 2 needs to be adjusted, the servo motor 302 drives the bidirectional lead screw 303 to rotate, causing the slider 304 on the surface of the bidirectional lead screw 303 to move closer to the center along the second slide rail 307. The slider 304 pushes the connecting seat 306 on the surface of the connecting rod 305 to drive the support frame 209 to slide and move downward on the surface of the first slide rail 211, thereby adjusting the depth of the cutter head 203 into the ground. The tips of the bidirectional lead screw 303 are all wedge-shaped threads with a 30-degree angle, thereby generating a self-locking capability. When the use is finished, the servo motor 302 can also drive the slider 304 to move outward, causing the support frame 209 to be raised and retracted into the outer casing 301, preventing the cutter head 203 from contacting foreign objects and causing damage to the blades, thus improving the adaptability of the device.

[0031] The working principle of this adjustable weeding device will be explained in detail below.

[0032] like Figure 1-5As shown, the motor 201 drives the rotating shaft 202 to rotate. At this time, the cutter disc 203 on the surface of the vertical rod 204 passes through the connecting groove 214 on the surface of the rotating shaft 202 via the internal fixing rod 213, so that the cutter disc 203 rotates when the rotating shaft 202 rotates. When it is necessary to adjust the spacing of the cutter disc 203, the electric telescopic rod 210 on the surface of the support frame 209 pulls the fixing platform 212, and the guide plate 207 moves upward. At this time, the sliding rod 205 slides on the surface of the sliding groove 208, so that multiple sets of vertical rods 204 slide on the surface of the limiting rod 206 and retract inward, thereby driving the cutter disc 203 to adjust the weeding spacing to adapt to different field needs. At the same time, the outer shell 301 protects the adjustment mechanism 2. When the adjustment mechanism needs to be adjusted... When the weeding depth is 2, the servo motor 302 drives the bidirectional lead screw 303 to rotate, causing the slider 304 on the surface of the bidirectional lead screw 303 to move closer to the center along the second slide rail 307. The slider 304 pushes the connecting seat 306 on the surface of the connecting rod 305, causing the support frame 209 to slide on the surface of the first slide rail 211 and move downward, thereby adjusting the depth of the cutter head 203 into the ground. The tips of the bidirectional lead screw 303 are all wedge-shaped threads with a 30-degree angle, thus generating a self-locking ability. When the use is finished, the servo motor 302 can also drive the slider 304 to move outward, causing the support frame 209 to be raised and retracted into the outer shell 301, preventing the cutter head 203 from contacting foreign objects and causing damage to the blades, thus improving the adaptability of the device.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
