Detailed Description

As shown in fig. 1-3, a tool bit of mountain soil loosening weeder, including blade disc 1 and the knife rest 2 of linkage assembly, blade disc 1 is equipped with two, and blade disc 1 divides in the relative both sides face department of knife rest 2, and the design of double-blade disc 1 is favorable to improving stability in use and high efficiency. The end face, back to the tool rest 2, of one side of the cutter head 1 is provided with a plurality of outer cutter assemblies, one side, facing the tool rest 2, of the cutter head 1 is provided with a plurality of inner cutter assemblies, and each of the outer cutter assemblies and the inner cutter assemblies comprises a vertical blade 3 and an inclined blade 4. The outer vertical blade 3 is used as a mowing blade, the inclined blade 4 is used as a loosening blade, and the loosening blade can prevent hard objects such as stones from damaging the mowing blade, such as a blade edge of the mowing blade. The vertical blade 3 of the inner blade assembly also serves as a mowing blade, and the inclined blade 4 serves as a ripping blade. And here to protect the fence. The plurality of groups of knife elements are arranged to ensure the use effect of weeding. A mowing knife 16 is further arranged between the cutterheads 1 to prevent grass or grass roots and other objects from being wound on the main shaft.

The vertical blades 3 and the inclined blades 4 are arranged at the outer edge of the cutter head 1, the vertical blades 3 are perpendicular to the radial direction of the cutter head 1, the inclined blades 4 form included angles with the radial direction of the cutter head 1, and the inclined blades 4 cover the vertical blades 3 locally on the radial direction of the cutter head 1. The provision of a peripheral edge prescription facilitates the processing and use, while the slight inclination of the inclined blades 4 facilitates the partial covering of the vertical blades 3, with a protective and stop function in the event of impact with large stones.

Be equipped with consecutive fixed disk 5 and ring flange 6 between blade disc 1 and the knife rest 2, fixed disk 5 is round platform shape structure, still be equipped with flange 7 on the fixed disk 5, be connected fixedly between blade disc 1 and the flange 7, between fixed disk 5 and the ring flange 6, be equipped with the projection 8 of connecting knife rest 2 on the ring flange 6. The structure of the connecting shaft can be shortened, the connecting structure at the connecting part is reinforced, and the disassembly and the assembly are convenient. Flange connection is favorable to strengthening to connect fixedly, compares traditional structure more firm, and under the comparison only need local dismantlement change spare part can.

The contour line of the inclined blade 4 is formed by connecting a plurality of arc edges, and the outer contour of the inclined blade 4 is bent and protruded towards one side of the vertical blade 3. The oblique blades 4 are in irregular geometric shapes, are more sensitive than regular shapes, and have higher probability of first contacting hard objects such as stones and the like.

The cutter head is characterized in that a mounting hole 9 is formed in the center of the cutter head 1, a plurality of first connecting holes 10 are formed in the outer edge of the mounting hole 9 of the cutter head 1 along the circumference, and second connecting holes 11 corresponding to the first connecting holes 10 are formed in the flange 7 of the fixed disc 5. The end face of one side of the fixed disc 5, corresponding to the mounting hole 9, is provided with a groove 12, and the bottom of the groove 12 is provided with a fixing hole 13 for connecting the flange 6. The junction has the hidden nature, is difficult for receiving external environment influence and not hard up, makes things convenient for the dismouting operation again. This is one particular embodiment and is not intended to be exhaustive or limiting.

The cutter rest 2 is provided with a baffle 14, the baffle 14 is of an arc surface structure bending towards one side of the cutter 1, and the baffle 14 is provided with a plurality of reinforcing ribs 15 on the inner side surface. The protection to personnel is enhanced by the baffle plate 14, and the structural strength can be improved by arranging the reinforcing rib 15 without needing excessive thickness to increase the weight and the use cost.
