Description

Technical Field

[0001] This utility model relates to the field of land development technology, and in particular to a weeding device for land development. Background Technology

[0002] In the process of land development, weed control is a fundamental and important task. Whether it is the reclamation of agricultural land, the preliminary treatment of construction land, or the land preparation for landscaping, it is necessary to efficiently remove surface weeds and their roots to prevent weeds from competing with crops for nutrients, affecting construction progress, or damaging the landscape effect.

[0003] Traditional manual weeding is inefficient and labor-intensive, while some mechanical weeding equipment suffers from limited functionality and poor adaptability, making it difficult to meet the diverse needs of different land development scenarios. Therefore, designing a device that can flexibly handle different weed types and soil conditions, and possesses efficient weeding capabilities, has become an urgent need.

[0004] This weeding equipment for land development was developed against this background. It aims to improve weeding efficiency and reduce labor costs in the land development process through innovative structural design, and to provide reliable technical support for land development work. Utility Model Content

[0005] The purpose of this utility model is to provide a weeding device for land development, which solves the problem mentioned in the background art that when no one is home, sunlight enters through doors and windows, causing the indoor temperature to be too high, resulting in a poor experience for users after returning home.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a weeding device for land development, comprising a housing, four wheels rotatably connected to both sides of the housing, a frame fixedly installed inside the housing, a first blade fixedly installed at the bottom of the frame, a retaining strip fixedly installed on the upper surface of the first blade, a second blade movably engaged inside the retaining strip, a weeding component installed above the second blade, ventilation windows provided on both sides of the housing near the wheels, a handrail fixedly installed on the side of the housing away from the ventilation windows, and an oil tank cap threadedly connected to the upper surface of the housing.

[0007] The weeding component includes a partition, which is fixedly installed inside the box. A gasoline engine is fixedly installed on the partition near the handrail. A flywheel is rotatably connected to one side of the gasoline engine. A pull rope is sleeved on the outside of the flywheel. A handle is movably installed on the side of the box near the handrail. The handle is connected to the pull rope. A fuel tank is fixedly installed on the upper surface of the gasoline engine. The upper surface of the fuel tank is threadedly connected to the fuel tank cap.

[0008] The partition plate is rotatably connected to a turntable on the side away from the gasoline engine. The turntable is fixedly connected to the output end of the gasoline engine. A convex shaft is fixedly installed on the side of the turntable away from the partition plate. The convex shaft is eccentrically positioned. A swing rod is slidably connected to the outside of the convex shaft. The swing rod is rotatably connected to the partition plate. A gear is fixedly installed at the bottom end of the swing rod.

[0009] Two fixing blocks are fixedly installed on the side of the partition near the turntable. A toothed slide rod is slidably connected inside the fixing block, and the toothed slide rod is meshed with a gear.

[0010] The toothed slide rod has two swing arms fixedly installed at both ends, and two follower rods are fixedly installed on the lower surface of the swing arms. The upper surface of the frame has a groove, and the groove is slidably connected to the follower rod.

[0011] A connecting block is fixedly installed at the bottom end of the follower rod, and the connecting block is fixedly connected to the second cutter.

[0012] This utility model discloses a weeding device for land development. One blade is fixed to the bottom of the frame, providing basic weeding functionality, while another blade is movably connected to the first blade via a locking strip. This design allows users to quickly replace the second blade according to different soil conditions and weed types. For example, it can be replaced with a deep-till blade to handle stubborn root weeds, or a flat-cutting blade to deal with common surface weeds, greatly improving the device's adaptability to complex weeding scenarios during land development. Simultaneously, the modular blade design reduces maintenance costs. When the blades wear out, only the corresponding blade needs to be replaced, without replacing the entire blade assembly, improving the device's efficiency. The weeding component employs a sophisticated mechanical transmission structure. After the gasoline engine starts, it drives the turntable to rotate. The eccentrically positioned cam shaft drives the swing rod to reciprocate, which, through the meshing of gears and a toothed slide rod, converts the rotational motion into the linear reciprocating motion of the slide rod, ultimately causing the second blade to swing up and down or vibrate. Compared to traditional single-rotation weeding methods, this vibration-based weeding method more effectively cuts weed roots, improving the thoroughness of weed removal. In addition, the components of the transmission system work closely together and the power transmission is stable, which can ensure that the equipment maintains high efficiency in weeding even after long-term operation.
