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, weeds in farmland are very harmful, 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 planted crops, making crops There is more space to flow air, which promotes photosynthesis; weeds stay in the soil after they die, and can also increase the organic matter content of the soil after being decomposed.

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

There are two types of existing crop weeding devices. One is to cut off the grass roots. This method is not thorough in weeding. Since the roots of the weeds are still in the soil below the surface, they will grow again once they reach a suitable temperature. Weeding operations. The other is to dig out the grass roots. It is necessary to insert the weeding tool under the ground 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 tool is prone to getting stuck or stuck when inserted into the ground surface. If it is not smooth, the work efficiency is poor.

Contents of the invention

To solve the problem, the present invention provides a kind of.

The technical solution 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, a plurality of connecting rods connected to the bottom surface of the top mounting plate, and a plurality of connecting rods The bottom ends of each are connected to the top surface of the bottom mounting plate, and a gear box is arranged between the top mounting plate and the bottom mounting plate. A plurality of connecting rods are connected to the gear box and run through the gear box, and a screw rod is pierced on the gear box. and a plurality of spiral loosening knives, the plurality of spiral loosening knives are evenly spaced along the circumference of the screw rod, a driving gear and a plurality of driven gears are arranged in the gear box, the driving gear is sleeved on the screw rod, and a plurality of slaves The driving gears are respectively set on multiple screw loosening knives, the driving gears and multiple driven gears are meshed respectively, the motor is installed on the bottom surface of the top mounting plate, and the output shaft of the motor is connected with the top of the screw rod so that the motor drives the wire at the same time. The rod and multiple spiral loosening knives rotate, and the bottom end of the spiral loosening knife penetrates the bottom mounting plate. When multiple spiral loosening knives rotate synchronously, they can cooperate to loosen the soil under the bottom mounting plate. The bottom end of the screw rod is installed There is a conical pressure plug, and the bottom side of the conical pressure plug is provided with jaws for clamping weeds. The jaws extend into the through groove of the bottom mounting plate and extend to the bottom of the bottom mounting plate. When the screw rod rotates, it can drive the cone The conical 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 opened. Two springs are arranged in the through groove of the bottom mounting plate. Two springs withstand both sides of the jaws respectively, and the jaws are pushed by the elastic force of the springs, so that the jaws in the open state return to the closed state when the conical pressure plug moves from the bottom side position to the top side position.

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

According to above-mentioned technical scheme, the beneficial effect of the present invention is:

The weeding device of the present invention not only has a plurality of spiral loosening knives capable of loosening the soil, but also has jaws capable of clamping weeds. When working, the soil near the weeds will be loosened first through a plurality of spiral loosening knives. Then the weeds are taken out from the soil through the claws, which can loosen the soil while weeding, without seriously damaging the soil structure, and can effectively avoid the jamming or unsmooth situation when the claws extend into the soil, significantly Improve the efficiency of weeding. The device can be installed on an automatic machine, and the precise removal of weeds can be realized through the visual positioning of the machine, which can effectively improve the weeding efficiency.

Detailed ways

Referring to the accompanying drawings, the specific implementation is as follows:

As shown in Figure 1, a kind of soil-loosening type crop weeding device comprises a top mounting plate 1 positioned at the bottom side of the weeding machine, and the bottom surface of the top mounting plate 1 is connected with two connecting rods 2 parallel to each other. The bottom ends are connected to 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, and the two connecting rods 2 are connected to the gear box 5 and run through the gear box 5, the gear box 5 A threaded mandrel 7 and three spiral loosening knives 6 are arranged on the top, and the three spiral loosening knives 6 are evenly spaced along the circumference of the threaded mandrel 7 .

As shown in Figure 2, a driving gear 11 and three driven gears 12 are arranged in the gear box 5, the driving gear 11 is set on the screw mandrel 7, and the three driven gears 12 are respectively set on the three screw loosening knives 6 Above, the driving gear 11 and the three driven gears 12 mesh respectively, and the motor 4 is installed on the bottom surface of the top mounting plate 1, and the output shaft of the motor 4 is connected with the top of the screw rod 7, so that the motor 4 drives the screw rod 7 and the three driven gears at the same time. A spiral soil loosening knife 6 rotates, and the bottom of the spiral soil loosening knife 6 runs through the bottom mounting plate 3, and three spiral loosening soil knives 6 can cooperate to loosen the soil below the bottom mounting plate 3 when three spiral soil loosening knives 6 rotate synchronously.

The bottom end of the screw mandrel 7 is equipped with a conical pressure bolt 8, and the bottom side of the conical pressure bolt 8 is provided with a jaw 9 for clamping weeds, and the jaw 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 jaws 9 are closed to the position where the jaws 9 are opened.
