Definitions
- the present invention relates to a device and a method for mechanical weed control.
- the invention relates to a device and a method for mechanical weed control of crop plants planted in series with woody soil shoots or trunks.
- the problem with all crop plants is that not only do the crops grow on the cultivation area, but also undesirable weed plants.
- the weed plants interfere with the cultivation of the crop plants.
- the weed plants have a negative effect on the desired harvest quantity and quality of the harvested fruits. For these reasons, the unwanted weed plants are usually removed.
- Soil cultivation tools are removed or pulled out of the ground.
- the crops are usually planted in rows for easy processing. With crops that have woody shoots or a stem, there is the problem that unwanted weed plants between the plant rows and individual Plants growing in a row of plants. These weed plants cannot, however, be removed with the conventional tillage implements known from agriculture, or can be removed only to a limited extent.
- Fingerhooks designed to tear out or damage the unwanted weed plants, which causes the weed plants to die.
- the pickaxe and roller hoe do not always reach the weed plants that are directly on the stem of the crop.
- the object is achieved by a device for mechanical
- Weed control comprising an agricultural vehicle with a predetermined direction of travel and two opposite longitudinal sides and one
- a tillage implement attached to the agricultural vehicle having at least one harrow with at least one tine comprising a tine arm, a tine tip and a tine base, the tine tip and the tine base being located at opposite ends of the tine arm, wherein the harrow is connected to a connecting element in the area of the tine base, the at least one tine of the harrow having a kink at a predetermined angle, at least the tine tip protruding beyond a longitudinal side of the agricultural vehicle and the tine arm being oriented at a predetermined angle with respect to the direction of travel is.
- the predefined and, in particular, adjustable angle is also referred to below
- the harrow can be attached to the front, back or side of the agricultural vehicle.
- the at least one tine usually protrudes completely beyond the long side of the agricultural vehicle. If the harrow is attached to the front or rear of the
- the at least one prong can partially or completely protrude beyond the long side of the agricultural vehicle.
- the at least one prong of the harrow can be brought up to the crop plant without hesitation in order to catch the weed plants, since the at least one prong, in contrast to a roller hoe, does not or does not seriously damage the stem of a crop plant, for example a vine or a fruit tree .
- the provision of a kink in the tine leads to improved protection of the crop plants, on the one hand, and on the other hand, the action of the harrow can be adapted to the external conditions due to the changeable predetermined angle of the kink.
- the kink in the tine can be provided in the tine tip, in the tine arm or between the tine tip and tine arm.
- Weed control is particularly effective when the tine arm points obliquely downward, the tine arm preferably being oriented rearward in the direction of travel, since the weed plants which have been torn out are then pulled away from the crop.
- the device is preferably designed to process crops in a row with a stem and a crown, the harrow being attached to the agricultural vehicle in such a way that the crop is processed by means of the harrow below the plant crown. In this way, the soil around the crop can be worked without the risk of damaging the crop.
- crown means the branches or shoots of a crop.
- the setting angle which the at least one prong has with respect to the horizontal is less than 45 °, preferably less than 30 °.
- a predetermined setting angle with respect to the horizontal has the advantage that the harrow in Near the vehicle can be guided at a distance from the ground, while the harrow can attack the ground in the area of the crop. This prevents
- Weed plants in the vicinity of the vehicle are torn out. This can be desirable for ecological reasons.
- these weed plants in the vicinity of the vehicle do not impair the effectiveness of the harrow.
- the angle should not be greater than 45 °, because a comparatively flat alignment of the tines is desired, particularly in the case of vines, since the harrow is then only guided below the shoots along the stem of the vine and thus does not damage the shoots of the vine.
- the vertical distance between the tine base and a bearing surface of the agricultural vehicle is approximately 20 cm to 70 cm, preferably 20 cm to 50 cm.
- the contact surface is understood here to mean the surface on the underside of the agricultural vehicle with which the agricultural vehicle, in particular with which the edges of the agricultural vehicle are on the ground, such as that
- This measure also contributes to the harrow being guided beneath the shoots of a plant by one
- Vehicle does not undesirably affect the weed plants during operation and is small enough to effectively remove the weed plants from the soil.
- an adjustment device is preferably provided.
- the adjusting device is designed to move the harrow in at least one spatial direction, preferably in three mutually perpendicular directions
- Adjustment device preferably has at least one lockable joint, in particular a toothed joint.
- the adjustment device is firmly connected to the connecting element of the harrow. This has the advantage that other tillage implements can be easily connected to the agricultural vehicle.
- the at least one prong is designed to be resilient in order to avoid any damage to the woody stems or soil shoots of the crop plants.
- the harrow has a spring element.
- the harrow comprises at least two tines arranged in parallel.
- the at least two tines arranged in parallel each have two opposite ends, the at least two tines arranged in parallel being connected to one another at one end. This can further improve weed control.
- the tillage device comprises a rotating tillage tool such as a roller hoe or a finger hoe.
- the use of the harrow in combination with a rotating tillage tool has proven to be particularly advantageous.
- the rotating tillage tool throws the soil up.
- the unwanted weed plants are torn out or damaged.
- the harrow is pulled in the direction of travel behind the tillage tool by the agricultural vehicle over the earth raised by the rotating tillage tool, which results in that of a rotating
- Soil cultivation tool is leveled thrown earth.
- the harrow ensures that those that have already been thrown or partially torn out
- the device for mechanical weed control is preferably used in plantings of crop plants which have a woody ground shoot or a woody trunk. So the device for mechanical weed control
- the present invention also relates to a method for mechanical weed control of crops in a row which have a woody soil shoot or a woody trunk, with a device according to the invention, the method being characterized by the following steps:
- the vehicle pulls the harrow and thus the tines across the ground.
- the harrow can be brought up to the stick or stem of the plant in order to also pull weeds that grow around the stem or stick out of the soil.
- the tine tip protrudes at least in sections laterally beyond the woody trunk or woody ground shoot of the crop plants in series, the length of the tine preferably being selected such that when aligning the at least one prong, about 5% to 30% of the length of the tine arm protrudes through the row of plants to be worked.
- plants that stand between the trunks or woody shoots of the crops in a row are also recorded.
- the at least one prong is guided at least in sections around the stem or woody soil shoot, so that the weed plants located in the immediate vicinity of the stem or woody soil shoot are removed.
- Soil cultivation tool is provided, which is arranged in front of the harrow in the direction of travel, the rotating tillage tool tearing open the soil around the woody trunk of the crop plants in row and / or damaging or at least partially tearing out the weed plants.
- the rotating tillage tool is guided at a safe distance from the stick or tree trunk to avoid damaging the crop itself.
- the harrow can then attack directly on the stick or on the tree trunk around the remaining weed plants to tear out.
- the harrow may level the earth raised by the rotating tillage tool.
