Description

Rotary Weeding Cultivator
Product Application
The product is a rotary weeding cultivator for garden work
The weeding cultivator is mounted on a special device. The weeding depth can be controlled with a lever. The cultivator has cutter teeth fixed to a shaft A driving mechanism makes the cultivator rotate.
Well-known technique
For weeding flower beds and garden paths there are many well-known tools such as different types of weeding hoes and motor-driven rotary cultivators.
The problem of traditional tools
It requires bodily strength to use the traditional weeding hoes and the motor-driven cultivator is too violent for use in flower gardens.
The product in question will solve many problems. It is easy to handle and it does not damage the plants.
The new technique
The weeding cultivator consists of hooks the number of which can be varied as required. The hooks are placed on a shaft with spacers. Everything is held together with a clasp nut. The weeding cultivator with shaft is mounted in a housing containing a shaft for trailing wheels providing transmission from driving mechanism to cultivator. A lever mounted in the housing ensures easy handling and operation.
The technical solution
A weeding cultivator based on the above technique makes weeding efficient and easy without damaging the plants.
The product in different versions are described and illustrated in the following.
List oif figures
Figure 1 Principle sketch of weeding cultivator
Figure 2. Major versions of weeding hoe
Figure 3 Double-shafted weeding cultivator
Figure 4 Complete tool with weeding cutters Figure 1 shows the weeding cultivator (1) mounted on a bent tube (2).
The weeding cultivator (1) consists of a variable number of weeding hooks (3) Spacers ensure that the hooks are positioned properly on the shaft (4). Everything is held together with a nut (6).
Rotation in both directions is induced by means of a driving shaft (7) and a shaft (4) connected in a bent tube (2) with suitable conical gear wheels.
The number of weeding hooks (3) applied can be varied from 1 and upward. The hooks are mounted with spacers (5) the number of which can be varned according to the weeding work in question. The optimal self-cleaning function will depend on the number of weeding hooks and spacers applied.
Figure 2 shows the weeding hoe (3). The weeding hoe (3) can be made of metallic material of different cross sections, for example round spring steel. The weeding hook has an eye (8) that matches to the shaft (4). The weeding hoe can be fitted with a shaft (9) that can be straight or bent (10) in distance a from eye 8 under an angle V, that can be varied to both sides as required. Angle V can have all sizes from o - 360° . The hook can also have a bending W (ιό) in distance b from eye 8 under angle W. It can vary between o - 360° The optimal self-cleaning function will depend on angles V and W.
Figure 1 shows the weeding cultivator (1) with bent tube (2) and with the shaft to one of the sides. Figure 3 shows another version with a shaft to both sides. To make this posible shaft 5 has been extended accordingly.
The bent tube (2) is a cylinder (17) that with a shaft (13) forms a T Transmission is induced through the shaft from motor (11) to shaft (5). The transmission can be a shaft and gear- wheel connections or a V- belt drive.
In a special version the cylinder (17) is replaced by an electric motor with shaft connection in both ends.
Weeding cultivator and bent tube can be combined to a complete weeding machine.
Figure 4 shows a sketch of the complete weeding machine.
