Chain-transmission weeding scarifier

Abstract

Disclosed is a chain-transmission weeding scarifier. A rear chain wheel is installed on a clutch which is installed at one end of a power device, a fixing frame with a cavity is mounted at the front end of a rack, the rear chain wheel is sleeved in the cavity of the rear end of the fixing frame, a front fork is arranged at the front end of the fixing frame, a rotary shaft is mounted in bearings at two ends of the front fork, a front chain wheel is mounted in the middle of the rotary shaft, the front end of the fixing frame is sleeved on the front chain wheel, and a chain is sleeved on the front chain wheel and the rear chain wheel. A plurality of cutter discs are fixed on the rotary shaft on two sides of the front chain wheel, and bent weeding cutters and winding grass cut-off cutters are mounted on the cutter discs. A push handle is mounted at the rear end of a rack and a controller of the power device is mounted on a handle shank of the push handle. An adjusting bar is installed below the rack, and wheels are mounted on the adjusting bar. During usage, an operator holds the handle shank and a handle by hands, weeding cutters below the rack are attached to the ground and can be pushed into lower portions of low fruit tree branches for weeding and soil scarifying conveniently. The chain-transmission weeding scarifier is ingenious in structure, low in weight, small in size and wide in applicable range.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a chain drive 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 tu...

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 chain drive weeding and scarifying machine. A power device is installed horizontally in the middle of the frame, and a centrifugal clutch is installed at one end of the output shaft of the power device. The transmission gear is installed in the box, the rear sprocket is installed on the output shaft of the gearbox, and a fixed frame with a cavity is installed at the front end of the frame. The rear spr
