Technical Field

[0001] The invention relates to the technical field of micro-tillage machines, in particular to a garden micro-tillage machine with anti-clogging and soil discharge function. Background Art

[0002] The garden tiller is a small agricultural machine, mainly used for basic farming operations such as tilling land, loosening soil, and weeding. It can also be equipped with different accessories to complete tasks such as sowing, fertilizing, and ditching. It is lightweight and flexible and suitable for farming in a smaller space. When the garden tiller is in use, weeds, roots and other obstacles in the soil may be entangled in the working parts, making it impossible to quickly discharge the soil after it is turned up, causing blockage, thereby affecting work efficiency and machine performance.

[0003] Existing garden micro-tillage machines usually have a spiral soil discharger at the rear to push the tilled soil to one or both sides to prevent the soil from piling up under the machine. However, this requires an additional drive structure, which is not energy-efficient. At the same time, if there is accumulated dead grass on the soil surface, it will affect the tillage effect. Summary of the invention

[0006] Preferably, an anti-collision rod is fixed to the front end of the mounting frame by bolts, and a limiting side plate is symmetrically fixed to the lower rear end of the mounting frame by bolts.

[0007] Preferably, an arc-shaped limiting groove is formed on the limiting side plate, and the arc-shaped structure of the arc-shaped limiting groove takes the driving shaft of the driving mechanism as the center point, and the end of the rotating component extends into the arc-shaped limiting groove.

[0008] Preferably, a connecting piece is fixed to the lower end of the connecting frame by welding, and a front end supporting wheel is fixed to the bottom of the connecting piece by a rotating rod.

[0009] Preferably, moving wheels are symmetrically provided on both sides of the rear of the mounting frame, and the spacing between the moving wheels is greater than the size of the rotating component.

At the same time, when the main transmission mechanism 502 is adjusted in angle, the height of the rotating part 8 can be controlled, thereby controlling the depth of plowing. A connecting frame 205 is connected to the front end below the mounting frame 2, and a connecting piece 202 is fixed to the lower end of the connecting frame 205 by welding, and a front end support wheel 4 is fixed to the bottom of the connecting piece 202 by a rotating rod.

The connecting frame 205 and the weeding scraper 7 are rotatably connected. The pneumatic support rod 3 of this structure can be self-expanding and used in conjunction with the spring 301, so that the pneumatic support rod 3 can support the connecting frame 205 and the weeding scraper 7 to ensure that the weeding rake 702 at the bottom of the weeding scraper 7 is always supported on the soil to clean up the dead grass and other impurities on the surface and avoid affecting the tillage effect of the tillage tool 801. The weeding scraper 7 is a folding plate structure, and a connecting shaft 701 passes through the upper end of the weeding scraper 7 and the connecting frame 205, and a weeding rake 702 is arranged under the weeding scraper 7. A rotating part 8 and a double-headed spiral device 10 parallel to each other are arranged under the mounting frame 2, and moving wheels 11 are symmetrically arranged on both sides of the rear of the mounting frame 2, and the spacing between the moving wheels 11 is larger than the rotating part 8, this structure makes the main body 1 of the garden micro-tillage machine move stably through the cooperation of the moving wheel 11 and the front-end supporting wheel 4, and the moving wheel 11 is not affected by the rotating part 8, and the main transmission mechanism 502 is installed between the middle part of the rotating part 8 and the driving mechanism 501, and the rotating part 8 and the two ends of the double-headed spiral device 10 are jointly provided with a positioning seat 9, and the rotating part 8 is evenly plugged and fixed with a tillage tool 801, and the top cover of the tillage tool 801 is provided with a soil-proof baffle 12.
