Vine Removal Device {The vien eliminator}

The present invention relates to a vine removal apparatus, and more particularly, to a vine removal apparatus used for removing vines for harvesting vegetable gardens or sweet potatoes before harvesting for the next farming.

In general, the process of cultivating the harvested vegetable garden, such as watermelon and melon, for the next farming, or before collecting the sweet potato, the root organism, requires the removal of vines distributed over the entire area of the field.

The stems of these vines extend over a large area along the surface of the stratum, irrespective of the ridges and valleys of the field, and are entangled with other neighboring stems.

If plowing is carried out by using a plane or a tractor without removing such vines, problems such as tangling of the vines with the machine are intensified, which makes it difficult to work and also causes the machine to malfunction. Occurs.

For this reason, the conventional process for removing vines consists of repeating the work of dividing the vines by workers in some area units. Also, the vine piles piled up in the field through the above process of the field are burned for use as compost, and the ashes obtained therefrom are scattered, or the vine piles are collected for livestock feed such as cattle or sheep. Was utilized.

The vine removal process described above not only requires a lot of labor, but also requires a lot of work time and ancillary post-treatment.

In an effort to solve such a problem, in the "cultivator attached sweet potato harvesting device" of the Republic of Korea Patent No. 652515, as shown in Figure 1, the technology of the sweet potato stem processing unit as a means for removing the vines of sweet potatoes before harvesting I introduced it.

However, the sweet potato stem processing unit of the above patent has the following problems in the vine removal process.

First, the vines generally start at the center of the patter and extend into the valley between the patter and the patter and other neighboring patters, while the sweet potato stem processing unit of the patent claims the removal of the vines from the center of the patter on both edges. Because it is limited to the area, there is a problem in that the vines of the area between the toad and the toad cannot be removed.

This requires further removal of the vines by the worker before plowing for subsequent farming, as it remains entangled with the soil dug during subsequent sweet potato harvesting.

Second, in general, the shape of the ridge is different in height, width, and distance between the ridge and the ridge, and the shape of the ridge may be changed more deeply due to precipitation, or the ridge may be crushed to fill the valley. The sweet potato stem processing unit of the patent does not correspond to the height and width of the patter, and if the patter is low, the vines remain.If the patter is relatively high and the rotary shaft is rotated while the tiller is stopped, the cutter will dig the patter. In addition, it can cause problems of damaging sweet potatoes close to the top of the toads.

Third, in the case of the sweet potato stem processing unit of the patent, there is a problem that can cause damage and breakage of the cutter and the support bracket to dig the upper part of the toad due to the difficulty in adjusting the height in response to the shape of the toad.

Fourth, the cutter of the sweet potato stem processing unit of the above patent has a problem in that it is inevitable to replace frequently as a consumable cost and manpower consumption and hassle.

From the above problem, I have filed a "vine removal device" of the Republic of Korea Patent Application No. 10-2008-0076350, the present invention is to secure the fourth problem of the prior art by reducing the consumption of the cutter to extend the life. .

The present invention is a cultivation device of the cultivation device of "cultivated sweet potato attached to the cultivator of the Korean Patent No. 652515" and the patent application No. 10-2008-0076350 of the above-mentioned problems of the prior art, the cutter is in contact with the upper surface of the ground or ridge It is to provide a vine removal apparatus to remove the vines more effectively while preventing.

A characteristic configuration of the present invention for achieving the above object is a main body that is selectively mounted on the hitch of the tiller; A height adjusting part installed at a link member hinged to a predetermined portion of the main body to adjust a rotation angle of the link member; A rotating shaft configured to rotate to the link member in a rod shape, to receive a rotational force through a connection with the PTO shaft of the tiller, and to connect a plurality of cutters to the hinges along a side circumference; And a rake installed at the main body or the hitch of the cultivator spaced apart from the radius of rotation of the cutter to lift the vines from the upper surface of the ground or ridge as the cultivator progresses.

In addition, the rake portion is supported to be supported by the support block and the support block is installed on the main body or the cultivator hitch is installed to be able to move up and down, the lower end protrudes downward to correspond to the upper surface of the ground and the ridge to the front Rakes with curved shaped portions; And receiving the support of the support block is preferably configured to include an adjusting portion for adjusting the height of the rake.

And, it is effective to further provide a leveler for providing a reference to the lower portion of the rake so that the lowered position of the rake at a certain height with respect to the upper surface of the ground or ridge.

According to the above-described configuration of the present invention, the height adjusting portion causes the cutter to rotate at a sufficiently spaced position not to contact the ground or the upper surface of the toad edge, and the rake moves the vine from the ground between the ground and the upper surface of the toad. By raising the cutter to be within the radius of the cutter, the rake of the cultivator is reduced instead of the wear and damage of the cutter, thereby extending the life of many cutters and reducing the cost and hassle of replacing them. There is an advantage to reducing.
