The invention can hang the machine body on the rear side of a vehicle head through the hook and can be driven by the vehicle body to move forward.
Generally, crops are planted in a planting area on a land, and weeds are easily grown in non-planting areas on two sides of the land. Before weeding, the planting area and the non-planting area are judged, and then the positions of the weeding claws on the lifting rod are adjusted, so that the two weeding claws are respectively positioned at two sides of the planting area and are arranged corresponding to the non-planting area. Then the lifting mechanism drives the lifting rod to descend, so that the tip of the tooth part is contacted with the ground. And then the vehicle head driving mechanism drives the vehicle head to move, the tooth parts hook the weeds in the moving process, so that the weeds are pulled up, and the claw bodies are in a curved surface shape which is sunken backwards, so that the weeds are caught. As the weeds fall more and more through the opening from the upper portion of the claw body into the collection bag.
The side retaining claws are formed on two sides of the claw body of the weeding claw. When weeds are hooked up by the tooth parts, the side blocking claws form a holding form, and the weeds are prevented from leaking from two sides.
The interval between two adjacent tooth parts is not suitable to be too large, the weed can be leaked from the tooth parts if the interval is too large, and the tooth parts are not easy to hook the weed and pull the weed out if the interval is too small.
After the weeding work is finished, the lifting mechanism can drive the lifting rod to rise, so that the weeding claw is not contacted with the ground.
In order to prevent the body from mistakenly touching the human or animal in front of the body in the process of moving, the object on the front side of the body is detected, the infrared detector sends out a detection signal, the control mechanism and the main control computer react to the detection signal, and the moving mechanism is controlled to stop moving.
In order to observe the situation near the ground conveniently, an observation mirror is further arranged, the situation near the ground can be transmitted into the cab through the observation mirror, an operator can observe the situation near the ground in the cab, and further judgment is made, for example, weeding operation is performed on the ground once again, and the like.
Preferably, in the automatic weeding farmland equipment, the bag bottom of the collecting bag is connected with a hanging rope, and the hanging rope is hung on a hanging ring arranged on the lifting rod.
The bag bottom of the collecting bag is connected with a hanging rope 12, and the hanging rope 12 can be hung on a hanging ring 13 of the lifting rod, so that the bag bottom of the collecting bag is lifted, and the bag body of the collecting bag is prevented from being dragged on the ground in the advancing process of the device. When the device travels to the terminus, the lanyard can be unwound.
Preferably, in the automatic weeding farmland apparatus, a distance detector is arranged below the lifting rod, a standard distance value is preset in the memory, the standard distance value is the distance value from the lifting rod to the ground when the lifting rod descends to the lowest position, the distance detector detects the actual distance from the lifting rod to the ground in real time after the lifting mechanism drives the lifting rod to descend, the control mechanism compares the actual distance with the standard distance value, and returns a command of continuing to descend to the lifting mechanism when the actual distance value is greater than the standard distance value.
The distance from the lifting rod to the ground is detected in real time through the distance detector, so that whether the lifting rod is in place or not is detected conveniently. Since the tips of the teeth can only touch the ground to effectively weed, the tips must be detected in real time by the distance detector, and the occurrence of the influence on the weeding efficiency caused by the fact that the tips of the teeth cannot touch the ground is avoided.
Preferably, in the automatic weeding farmland equipment, the bottom of the machine body 1 is provided with a wheel body.
Preferably, in the automatic weeding farmland equipment, the interval between two adjacent tooth parts 6 is 1.5 cm.
The interval between two adjacent tooth parts is not suitable to be too large, the weed can be leaked from the tooth parts if the interval is too large, and the tooth parts are not easy to hook the weed and pull the weed out if the interval is too small.
Preferably, in the automatic weeding farm equipment, two sides of the opening 4 are aligned with two side teeth of the plurality of teeth 6. In this embodiment, weeds can more easily fall through the opening into the collection bag.
Preferably, in the automatic weeding farmland equipment, the tips of the teeth are connected with the cutting parts 10 which extend forwards and are transversely arranged, and the cutting parts of two adjacent teeth are not contacted with each other.
The front side of each tooth part is also connected with a cutting part, and the cutting parts can cut off the grass stems of weeds which are particularly difficult to pull out, so that the weeding efficiency is improved. However, in order not to interfere with the teeth catching the weeds, the cutting portions of two adjacent teeth cannot be connected to each other.
Preferably, in the automatic weeding farmland equipment, the weeding claw is fixed on the lifting rod through a detachable clamping and fixing part. After the weeding claw moves to a proper position, the weeding claw can be fixed by adopting a clamping and fixing component in the prior art.
