Description

Technical Field

[0001] This utility model relates to the field of micro-tiller technology, and in particular to a grass-cutting device for micro-tillers. Background Technology

[0002] In traditional agricultural machinery, mini tillers can only be used for plowing, while mowing requires a mowing machine, which incurs higher purchase costs and labor costs. Moreover, the mowing devices commonly used in mini tillers on the market are complex in structure, cumbersome to operate, lack flexibility, and are inconvenient to disassemble or replace the mowing disc, making them increasingly unable to meet people's daily needs.

[0003] A search revealed that existing technology CN209787862U discloses a grass-cutting device for a micro-tiller. Addressing the problems of complex structure, cumbersome operation, poor flexibility, and inconvenience in disassembling or replacing the grass-cutting disc in existing micro-tiller grass-cutting devices, the following solution is proposed: It includes a micro-tiller base, with a servo motor and two vertical plates fixed to the bottom end of the base. The servo motor is located between the two vertical plates. Rollers are rotatably connected to one side of the bottom end of each of the two vertical plates via bearings. The output shaft of the servo motor is driven by a mounting block, with limit grooves on both sides of the mounting block. A grass-cutting disc is located below the micro-tiller base, with multiple blades fixed to its edge. This utility model has a reasonable design, compact structure, simple operation, and facilitates the disassembly or replacement of the grass-cutting disc. It improves the stability and flexibility of the grass-cutting disc, meeting the daily needs of users and is suitable for widespread application.

[0004] However, the above-mentioned device has the following problems when in use: it cannot adjust the position of the grass cutter according to the height of the grass, and its practicality is poor. Utility Model Content

[0005] The purpose of this invention is to provide a grass-cutting device for a micro-tiller, which solves the problem that existing grass-cutting devices cannot adjust their cutting position according to the height of the grass, resulting in poor practicality.

[0006] To achieve the above objectives, this utility model provides a grass-cutting device for a micro-tiller, including a frame, a movable component at the bottom of the frame, a pushing component at the rear, and an adjusting component; The adjustment assembly includes a mounting plate, a connecting rod, a sliding sleeve, a cutter shaft, an auxiliary gear, a main gear, a drive motor, a guide block, a guide rod, an adjusting screw, a nut, and a cutting component. The mounting plate is located below the frame. The connecting rod is mounted on the rear side of the mounting plate and slidably connected to the sliding sleeve. The sliding sleeve is fixed to the frame. The cutter shaft is rotatably mounted on the mounting plate, and the cutting component is located at its bottom. The auxiliary gear is fixed to the top of the cutter shaft. The drive motor is mounted on a detachable U-shaped frame of the mounting plate, and the main gear, which meshes with the auxiliary gear, is fixed to its output end. The guide block is fixed to the top of the frame and symmetrically arranged. The guide rod is integrally formed with the mounting plate and slidably engages with a linear bearing on the guide block. The adjusting screw is fixed to the top of the connecting rod and passes through the frame. Two nuts are mounted on the adjusting screw and abut against the frame.

[0007] The movable component includes a connecting frame and movable wheels. The connecting frame is installed at the bottom of the frame and is symmetrically arranged. The movable wheels are rotatably installed at the bottom of the connecting frame.

[0008] The pushing assembly includes a fixed frame and push rods. The fixed frame is installed on the rear side of the frame and is symmetrically arranged. The push rods are welded between the fixed frames.

[0009] The cutting component includes a cutter disc and blades. The cutter disc is integrally formed with the cutter shaft and is located at the bottom of the cutter shaft. A plurality of blades are integrally formed with the cutter disc and are arranged in a ring at uniform intervals.

[0010] The micro-tiller's grass-cutting device also includes a setting component, which includes a fixing base and a cable conduit. The fixing base is mounted on the mounting plate and is close to the drive motor. The cable conduit is welded to the fixing base, is L-shaped, and is vertically arranged.

[0011] This utility model discloses a grass-cutting device for a micro-tiller. By cooperating with a pushing component and a moving component to move the frame, the device can be moved. Then, the drive motor is controlled to rotate the main gear, which in turn drives the auxiliary gear to rotate, thus rotating the cutter shaft. Finally, after the cutting component rotates, grass cutting can be performed. When it is necessary to adjust the grass cutting position according to the grass height, the drive motor is stopped, and the vertical position of the connecting rod is adjusted by the nut, thereby adjusting the vertical position of the mounting plate and the height of the cutting component. This solves the problem that existing grass-cutting devices cannot adjust the grass cutting position according to the grass height, resulting in poor practicality. Attached Figure Description
