Description

Technical Field

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

[0002] Weeders are primarily used to remove weeds between crop rows and plants, reducing their competition for water, nutrients, and light. Their core working components are typically rotating blades, hoe teeth, or weeding shovels, and they are either tractor-tethered or self-powered. During operation, the blades rotate at high speed or the hoe teeth precisely penetrate the soil, cutting the weeds at the root or uprooting them and burying them. This mechanical weeding method efficiently replaces heavy manual labor, significantly saving labor costs and time, and avoiding the problem of chemical herbicide residues. Timely and effective mechanical weeding helps protect soil moisture, improves field ventilation and light penetration, directly promotes healthy crop growth, and ultimately increases yield and quality. Therefore, weeders are an indispensable tool for achieving efficient and sustainable production in modern agriculture.

[0003] There may be large areas of weeds between the rows. Although these weeds are not directly attached to the crops, they may steal nutrients from the crop roots. Currently, some self-propelled weeding equipment often has inconvenient blade raising and lowering, and there may be weeds entangled in the ground or small stones that may damage the blades, so its practicality needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide an agricultural weeding machine with adjustable height to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-height agricultural weeding machine, including a mobile platform and a cutting platform disposed on one side of the mobile platform, wherein a lifting auxiliary mechanism and a weed cutting mechanism are disposed on one side of the mobile platform, and the weed cutting mechanism is disposed below the lifting auxiliary mechanism;

[0006] The lifting auxiliary mechanism includes multiple hydraulic cylinders, which are respectively fixedly connected to both sides of the moving platform. Each hydraulic cylinder has a piston plate that is sealed and slidably connected inside. Each piston plate has a bracket fixedly connected to its upper surface.

A sliding rod is fixedly connected to the upper surface of the cutting platform and is slidably connected inside the moving platform.

[0007] Preferably, each of the hydraulic cylinders is internally connected to a hydraulic control port.

[0008] Preferably, the support has an approximately U-shaped cross-section.

[0010] Preferably, the grass-cutting mechanism includes a support sleeve, which is fixedly connected to the upper surface of the cutting table. A mounting box is fixedly connected to one side of the support sleeve, and a cutting motor is fixedly connected inside the mounting box. Multiple turntables are rotatably connected inside the support sleeve. The output end of the cutting motor is fixedly connected to one of the turntables. A drive belt is fixedly connected between the turntables. A wheel is fixedly connected to the side of the turntable away from the cutting motor. An eccentric bushing is rotatably connected to one side of the wheel. A traction seat is rotatably connected to one end of the eccentric bushing.

A lifting auxiliary mechanism 3 and a weed cutting mechanism 4 are provided on one side of the mobile platform 1, and the weed cutting mechanism 4 is located below the lifting auxiliary mechanism 3.

[0026] This mechanism is used to adjust the height of the mower blade and assist in weeding. It reduces the probability of damage to the mower blade and improves the flexibility of the device. The lifting auxiliary mechanism 3 includes multiple hydraulic cylinders 301, which are fixedly connected to both sides of the moving platform 1. Each hydraulic cylinder 301 has a piston plate 302 that is sealed and slidably connected inside. Each piston plate 302 has a bracket 303 that is fixedly connected to the upper surface of the piston plate 302. Multiple brackets 303 are fixedly connected to the cutting table 2. Each bracket 303 has a support 304 that is fixedly connected to one side. Each support 304 has a housing 305 that is fixedly connected to one side. A pulverizing motor 306 is fixedly connected inside the housing 305. A rotating rod 307 is fixedly connected to the output end of the pulverizing motor 306. Multiple angular blades 308 are fixedly connected to the outer wall of the rotating rod 307. Each angular blade 308 has a hammer head 309 fixedly connected to its end. The angular blades 308 are evenly distributed on the outside of the rotating rod 307. A sliding rod 310 is fixedly connected to the upper surface of the cutting table 2 and is slidably connected inside the moving platform 1.

[0027] Furthermore, hydraulic cylinders 301 are all equipped with hydraulic control ports.

[0028] Furthermore, the support 303 has an approximately U-shaped cross-section.

[0029] Furthermore, the support 304 and the upper surface of the cutting table 2 are set at an acute angle. Example

[0030] This device is used to cut weeds and is more efficient than disc-shaped weed cutters. Please refer to [link / reference]. Figure 1-5 Furthermore, in conjunction with Embodiment 1, the grass-cutting mechanism 4 includes a support sleeve 401, which is fixedly connected to the upper surface of the cutting table 2. A mounting box 402 is fixedly connected to one side of the support sleeve 401. A cutting motor 403 is fixedly connected inside the mounting box 402. Multiple turntables 404 are rotatably connected inside the support sleeve 401. The output end of the cutting motor 403 is fixedly connected to one of the turntables 404. A drive belt 405 is fixedly connected between the turntables 404. A wheel 406 is fixedly connected to one side of a turntable 404 away from the cutting motor 403. An eccentric bushing 407 is rotatably connected to one side of the wheel 406. A traction seat 408 is rotatably connected to one end of the eccentric bushing 407. A fixed blade 409 is fixedly connected to the lower surface of the cutting table 2. A slide table 410 is fixedly connected to the upper surface of the cutting table 2. The traction seat 408 and the slide blade 411 are both slidably connected inside the slide table 410. The traction seat 408 is rotatably connected to one end of the slide blade 411.

[0031] Furthermore, the drive belt 405 has a toothed structure inside that meshes with the turntable 404.

[0032] Furthermore, the eccentric bushing 407 is located on the outside of the rotor 406.

[0033] In actual operation, when this device is used, the user transports it to the area to be weeded. The user then adjusts the hydraulic pressure inside the hydraulic cylinder 301 to raise or lower the cutting platform 2. The user can lower the cutter to a suitable area and start the pulverizing motor 306 and the cutting motor 403. When the pulverizing motor 306 outputs power, it drives the rotating rod 307 to rotate. The rotating rod 307 drives multiple angled blades 308 and hammers 309 to rotate at high speed. After the angled blades 308 come into contact with the tangled weeds, they will cut the tangled weeds through their inertia, reducing the risk of weed entanglement. Simultaneously, the hammers 308... When the 09 is close to the ground, it can strike the stones to break them or send them out of the weeding area, thereby reducing the risk of damage to the sliding blade 411. During the output of the cutting motor 403, the cutting motor 403 drives the turntable 404 to make the rotating wheel 406 rotate at high speed. The rotating wheel 406 drives the eccentric bushing 407 to reciprocate, thereby causing the sliding blade 411 to slide back and forth inside the slide table 410. After the sliding blade 411 and the slide table 410 are misaligned, the weeds are cut, so that the weeds can quickly fall down where the sliding blade 411 passes, thus ensuring the cutting efficiency of the device.
