Description

A soil loosening type crop weeding device

technical field

The invention relates to the field of weeding devices, in particular to a soil loosening type crop weeding device.

Background technique

During agricultural planting, the weeds in the farmland have great harm, affecting the quality and yield of crops. After weeding, it not only reduces the absorption of soil nutrients and water by weeds, but also changes the spatial structure of planting crops. There is more space for air to flow, which promotes photosynthesis; weeds remain in the soil after they have been cut off, and they can also increase the organic matter content of the soil after being decomposed.

The methods of weeding in farmland usually include manual weeding, mechanical weeding, chemical weeding and so on. Among them, manual weeding not only requires a lot of labor, but also is time-consuming and labor-intensive. Chemical weeding is relatively time-saving and labor-saving, but pesticides have toxic components, which can easily cause pesticide residues on crops or soil if not handled properly, which not only pollutes the environment, but also poses health hazards to consumers. Compared with the above two methods, mechanical weeding is not only efficient but also safer.

The existing crop weeding devices are divided into two types. One is to cut off the grass roots. This method is not thorough in weeding. Because the roots of the weeds are still in the soil below the surface, once they reach a suitable temperature, they will re-grow. Weeding work. The other is to dig out the grass roots, which requires weeding tools to be inserted under the surface. Although weeds can be removed, this method seriously damages the hierarchical structure of the soil, causing the soil to lose more water, and the weeding tools are prone to sticking or jamming when they are inserted into the surface. Unsmooth situation, poor work efficiency.

SUMMARY OF THE INVENTION

To solve the problem, the present invention provides one.

The technical scheme adopted by the present invention to solve the above-mentioned technical problems is: a soil loosening type crop weeding device, comprising a top mounting plate located on the bottom side of the weeding machine, the bottom surface of the top mounting plate is connected with a plurality of connecting rods, and the plurality of connecting rods The bottom ends are connected with the top surface of the bottom mounting plate, a gear box is arranged between the top mounting plate and the bottom mounting plate, a plurality of connecting rods are connected with the gear box and pass through the gear box, and a screw rod is passed through the gear box And a plurality of helical scarifiers, the plurality of helical scarifiers are evenly spaced along the circumference of the lead screw, a driving gear and a plurality of driven gears are arranged in the gear box, the driving gear is sleeved on the lead screw, and a plurality of slave gears are provided. The moving gears are respectively fitted on the multiple screw rippers, the driving gear and the multiple driven gears are meshed respectively, the bottom surface of the top mounting plate is installed with a motor, and the output shaft of the motor is connected with the top of the screw rod, so that the motor can drive the screw at the same time. The rod and multiple screw rippers rotate. The bottom end of the screw ripper penetrates the bottom mounting plate. When the multiple screw rippers rotate synchronously, they can cooperate with the soil under the bottom mounting plate to loosen the soil. The bottom end of the screw rod is installed There is a conical pressure bolt. The bottom side of the conical pressure bolt is provided with a clamping claw for clamping weeds. The clamping claw extends into the through groove of the bottom mounting plate and extends to the bottom of the bottom mounting plate. When the screw rotates, it can drive the cone. The shaped pressure bolt moves in the vertical direction, so that the conical pressure bolt can move downward from the top side position where the jaws are closed to the bottom side position where the jaws are open. The two springs bear against the two sides of the jaws respectively, and push the jaws by the elastic force of the springs, so that the jaws in the open state are returned to the closed state when the conical pressure pin moves from the bottom side position to the top side position.

Preferably, the bottom surface of the top mounting plate is connected with two connecting rods that are parallel to each other, and the two connecting rods are symmetrically arranged with respect to the screw rod.

According to the above-mentioned technical scheme, the beneficial effects of the present invention are:

The weeding device of the present invention is provided with a plurality of spiral rippers capable of loosening soil, and also has a clamping claw capable of gripping weeds. When working, the soil near the weeds will be loosened by the plurality of spiral rippers first. Then the weeds are taken out from the soil through the gripper, which can loosen the soil at the same time as weeding is achieved, without seriously damaging the soil structure, and can effectively avoid the jamming or unsmooth situation when the gripper extends into the soil, significantly Improve the efficiency of weeding. The device can be installed on an automated machine, and can accurately remove weeds through the visual positioning of the machine, which can effectively improve the efficiency of weeding.

Detailed ways

Referring to the accompanying drawings, the specific embodiments are as follows:

As shown in Fig. 1, a soil loosening type crop weeding device includes a top mounting plate 1 located on the bottom side of the weeding machine. The bottom surface of the top mounting plate 1 is connected with two connecting rods 2 that are parallel to each other. The bottom ends are all connected with the top surface of the bottom mounting plate 3, a gear box 5 is arranged between the top mounting plate 1 and the bottom mounting plate 3, the two connecting rods 2 are connected with the gear box 5 and pass through the gear box 5, and the gear box 5 A screw rod 7 and three helical scarifier knives 6 are threaded on the top, and the three helical scarifier knives 6 are evenly spaced along the circumference of the screw rod 7 .

As shown in FIG. 2 , the gear box 5 is provided with a driving gear 11 and three driven gears 12 , the driving gear 11 is sleeved on the lead screw 7 , and the three driven gears 12 are respectively sleeved on the three spiral rippers 6 On the top, the driving gear 11 and the three driven gears 12 are meshed respectively, the bottom surface of the top mounting plate 1 is mounted with a motor 4, and the output shaft of the motor 4 is connected with the top of the screw 7, so that the motor 4 drives the screw 7 and the three Each spiral ripper 6 rotates, and the bottom end of the spiral ripper 6 penetrates the bottom mounting plate 3 .

The bottom end of the screw rod 7 is installed with a conical pressure bolt 8, and the bottom side of the conical pressure bolt 8 is provided with a clamping claw 9 for clamping weeds, and the clamping claw 9 extends into the through groove of the bottom mounting plate 3 and extends to Below the bottom mounting plate 3, when the screw rod 7 rotates, it can drive the conical pressure bolt 8 to move in the vertical direction, so that the conical pressure bolt 8 can move downward from the top side position where the clamping jaws 9 are closed to when the clamping jaws 9 are opened. On the bottom side, two springs 10 are arranged in the through grooves of the bottom mounting plate 3. The two springs 10 respectively bear against both sides of the clamping jaws 9, and push the clamping jaws 9 through the elastic force of the springs 10, so that the conical pressure bolt 8 Returns the jaws 9 in the open state to the closed state when moving from the bottom side position to the top side position.

When working, the weeding device is first brought to the top of the weeds by the weeding machine, and then the motor is started.
