Technical Field

The invention relates to the field of garden machinery manufacturing, in particular to a harvesting device of a brush cutter.

Background

The brush cutter, also called as a backpack mower, can be carried on the back and carried by hands, and is mainly used for sweeping edges of large-area lawns or trimming hay shrubs. The multifunctional forest cutting machine is used as one of forest farming machines, and is used for cutting off shrubs and weeds, pruning, cutting small-diameter trees, cutting bamboos and the like in forest land cleaning, young forest tending, secondary forest reconstruction, forest tending and felling and the like. The brush cutter is provided with some replaceable additional devices or equipment, and can also be used for harvesting crops such as rice and wheat, and the like, and the operations of pumping water, drilling holes, spraying pesticides and the like.

The existing brush cutter technical research is mature day by day, like the brush cutter used for harvesting crops, the design always needs to consider the arrangement condition of the harvested crops and the grass winding problem of a cutter head, so that the grain collecting function and the grass winding prevention function of the brush cutter need to be designed, the superiority of the two functional designs determines the product performance of the brush cutter, and the service life of the brush cutter is influenced.

Disclosure of Invention

The invention aims to provide a harvesting device of a brush cutter, which is provided with a grain collecting device of the brush cutter and a grass winding prevention device, so that the brush cutter can well place crops during working, and the grass winding problem of a cutter head is solved through the control of grass winding prevention, so that the brush cutter does not need to be stopped frequently during working, the working efficiency is improved, and the service life is prolonged.

The utility model provides a brush cutter reaping apparatus, its includes grass collecting device, action bars, blade disc, transmission, screw, and transmission passes through the transmission shaft and is connected with the blade disc drive to place in the blade disc top, its characterized in that: the grain collecting device is vertically arranged above the cutter head and comprises a support and a bottom plate, two fastening screws are arranged on the bottom plate and used for fixedly mounting the grain collecting device on the cutter head, and a grass winding prevention device is sleeved on the outer side of a transmission shaft connected with the cutter head.

As a preferred example, the anti-winding device is a hollow shaft device with a circle of eccentric blades, the rotation direction of the blades biased to the cutterhead is opposite, and the grass-cutting device cuts weeds wound between the cutterheads when the brush cutter works.

As a preferable example, the grass winding prevention device is fixedly welded on the cutter head, the inner diameter of the shaft hole of the grass winding prevention device is larger than or equal to the outer diameter of the transmission shaft, and the transmission shaft passes through the shaft hole of the grass winding prevention device during installation.

As a preferred example, the height of the grass winding prevention device is about 5 mm-1 cm, so that the grass winding amount of the cutter head can be maximally reduced, and meanwhile, weeds wound on the grass winding prevention device can be removed.

Compared with the brush cutter technology, the invention has the beneficial effects that: the grass collecting device and the grass winding prevention device of the brush cutter are simple in structure and low in cost, crops can be well placed when the brush cutter works, the grass winding problem of the cutter head is solved, the brush cutter does not need to be stopped frequently to clean when working, the working efficiency is improved, and the service life is prolonged.
