Description

Technical Field

[0001] The utility model relates to an agricultural machine, in particular to a hole-opening device composed of a rotating wheel and a hole-opening cone. Background Art

[0002] Chinese patent CN209283683U discloses a multifunctional hole digger for planting salvia miltiorrhiza, which has the following structural features: it includes a handrail, a ground wheel and a hole digging mechanism arranged on the ground wheel, a dial is arranged on one side of the ground wheel, an observation window for observing the dial is arranged on the handrail, and a first pointer is arranged on the observation window, and the indicating end of the first pointer points to the graduation line of the dial. When in use, the operator can hold the handrail and then push the handrail to realize the rolling of the ground wheel on the ground. During the rolling process of the ground wheel, when the hole digging mechanism contacts the ground, the hole digging mechanism can perform hole digging and realize the digging process. Since the structure is that the hole digging mechanism is arranged on the outer surface of the ground wheel, the distance between the acupoints is fixed. Since the ground wheel is light, it is not easy to crush the soil block when encountering harder soil or more severe soil compaction, so the operator needs to transfer the downward pressure to the ground wheel through the handrail, which has a large labor intensity and low work efficiency, thereby affecting the progress of the operation. Summary of the invention

[0003] The utility model aims to provide a hole opener which can adjust the distance between the acupoints according to the planting row spacing requirements, reduce labor intensity, improve work efficiency, and has low cost and is easy to carry.

[0004] To achieve the above-mentioned purpose, the utility model provides a hole opening device, including a rotating wheel and a hole opening cone, wherein a plurality of hole opening cones are evenly distributed on the outer surface of the rotating wheel, an elastic ring is arranged on the outer ring of the rotating wheel, a hole opening ring is installed outside the elastic ring, the hole opening ring is connected to the rotating wheel through the elastic ring, and the hole opening ring is also connected to the rotating wheel through at least two locking structures.

[0005] The hole-opening ring is composed of an outer ring and hole-opening cones, and a plurality of hole-opening cones with triangular radial cross sections are evenly distributed on the outer surface of the outer ring.

[0006] The hole opening cone is arranged in an isosceles triangle shape.

[0007] A disconnection point is arranged on the outer ring, and the disconnection point is connected by bolts.

[0008] The elastic ring is made of rubber.

[0009] The rotating wheel is composed of a wheel rim, spokes and a shaft sleeve, one end of a plurality of spokes is radially connected to the outer surface of the shaft sleeve, and one end of a plurality of spokes is radially connected to the inner surface of the wheel rim.

[0010] The spokes are made of steel pipes.

[0011] The locking structure is arranged in a U shape, and the U-shaped opening is connected by bolts.

[0012] After adopting this structure, since an elastic ring is arranged on the outer ring of the rotating wheel, a hole-opening ring is installed outside the elastic ring, the hole-opening ring is connected to the rotating wheel through the elastic ring, and the hole-opening ring is also connected to the rotating wheel through at least two locking structures. Thus, the distance between the acupoints can be adjusted according to the requirements of the planting row spacing, and the labor intensity can be reduced, the work efficiency can be improved, and the cost is low and it is easy to carry.
