Detailed Description
In order to explain the technical content and the structural characteristics of the long and short teeth bionic cassava digger shovel in detail, the following description is further provided with the embodiment and the accompanying drawings.
As shown in fig. 1, 2, 3, the utility model relates to a bionical type cassava digger blade of length tooth, including supporting mount 1, support mount 1 bottom transversely is equipped with triangular prism supporting beam 101, and triangular prism supporting beam 101's cross section is triangle-shaped, alternately is equipped with on the triangular prism supporting beam 101 front end inclined plane and excavates long tooth 2 and the short tooth 3 that breaks ground, and the length of excavating long tooth 2 is greater than the length of the short tooth 3 that breaks ground. When hilling occurs above the shovel body, because the length of the digging long teeth 2 is greater than that of the soil breaking short teeth 3, gaps exist in the extending direction, the hilling above the shovel body can fall off conveniently, the hilling above the shovel body can be broken when the soil breaking short teeth 3 continue to move, meanwhile, the triangular angle of the cross section of the triangular prism supporting cross beam 101 is matched with the soil flowing direction, and the soil piled in the front direction can be thrown backwards conveniently.
The left side and the right side of the supporting and fixing frame 1 are provided with fixed vertical beams 102, the fixed vertical beams 102 are sequentially provided with lower end fixing holes 103 and upper end fixing holes 104 which penetrate through the fixed vertical beams 102 from bottom to top, and the fixing holes of different appearances are convenient for later-stage digging shovel installation.
Excavation long tooth 2 and broken soil short tooth 3 have the same camber on the forming relieved tooth extending direction vertical plane, excavation long tooth 2 and broken soil short tooth 3 have the camber on the forming relieved tooth extending direction vertical plane, be through confirming the camber of bionical simulation department to chinese countryside dog palm, excavation long tooth 2 and broken soil short tooth 3 have the same camber and can guarantee that excavation tooth 2 and broken soil tooth 3 atress are the same in advancing, prevent to cause equipment to warp because of the atress inequality.
Digging long teeth 2 and broken soil short teeth 3 have certain same radian on the horizontal plane of the extending direction of the shovel teeth, so that the shovel teeth are easy to enter the soil and even in stress, the distance between the shovel teeth is even, the soil block above the shovel body is convenient to fall off, and the load of the tractor is reduced.
