Shaft drive weeding and scarifying machine

Abstract

Disclosed is a shaft-driven weeding ripper. A centrifugal clutch is mounted at the front end of a power device on a frame, an output shaft of the centrifugal clutch is connected with an input shaft of a gearbox, a variable-speed gear is mounted in the gearbox, a fixing rod is mounted at the front end of the gearbox, a long shaft is sleeved in the fixing rod, the rear end of the long shaft is connected with an output shaft of the gearbox, a bevel gear is mounted at the front end of the long shaft, a front fork is fixedly mounted at the front end of the fixing rod, bearings are mounted at two ends of the front fork, two ends of a rotating shaft are mounted on the bearings, a fluted disc is fixedly mounted in the middle of the rotating shaft and engaged with the bevel gear, a plurality of cutter heads are mounted on two sides of the fluted disc on the rotating shaft, bent weeding cutters are mounted on the cutter heads, a push rod is mounted on the upper portion of the frame, a controller for the power device is mounted on a handle at the tip of the push rod, an adjusting rod is mounted below the gearbox, and wheels are mounted below the adjusting rod. The bevel gear and the fluted disc are used for driving the rotating shaft, and the weeding cutters on the rotating shaft loosen topsoil and cut off weeds together with roots when rotating. The shaft-driven weeding ripper has the advantages of exquisite structure, light weight, small size and operational flexibility.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a shaft-driven weeding and loosening machine, which is especially suitable for weeding and loosening of mountain coffee plantations. Background technique [0002] In the prior art, what is close to the technology of the present invention is a small rotary tiller driven by the tractor head and composed of a rotary tiller, a walking mechanism and a direction control mechanism. Its volume, weight and output power are relatively large, and it is suitable for Plow and weed the open fields after the crops have been harvested. For some special orchards, such as: coffee plantations, mountain orchards, etc., the terrain is undulating, the branches of the fruit trees are low, and the branches will bear fruit. The existing small rotary tillers cannot perform weeding and loosening in these special orchards. For soil work, there are problems such as difficulty in driving in and t...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, it is difficult to weed and loosen the soil in special mountain orchards such as coffee plantations, and the existing small-scale rotary tillers cannot work in it. The artificial weeding method requires many personnel, high labor intensity, and low work efficiency. For the problem of poor economic benefits, the present invention provides a shaft drive weeding and scarifying machine. A power device is installed on the frame, and a centrifugal clutch is installed at the front end of the power device. The output shaft of the centrifugal clutch is connected with the input shaft of the gearbox, and the gearbox There is a speed change gear installed inside, a fixed rod is installed at the front end of the gearbox, the long shaft is sleeved in the fixed rod, the long shaft is connected to the output shaft of the rear gearbox, a bevel gear is installed at the front end, a front fork is fixedly installed at the front end of the fixed rod, and the two ends of the front fork Bearings are installed, the two ends of the rotating shaft are installed on the bearings, the middle of the rotating shaft is fixedly equipped with a toothed disc, and the toothed disc meshes with the bevel gear. Multiple cutter heads are installed on the rotating shafts on both sides of the toothed disc, and curved weeding knives are installed on the cutter head. A push rod is installed above the frame, a controller of the power unit is installed on the handle at the end of the push rod, an adjusting rod is installed under the gearbox, and a wheel is installed under the adjusting rod
