Embodiment Construction

[0013] The invention will be further described below in conjunction with the accompanying drawings and embodiments. A fitting curve type subsoiling shovel is composed of three parts: the connecting section (L) between the shovel handle and the frame, the working section (II) of the shovel handle, and the connecting section (R) between the shovel handle and the shovel tip. The connecting section (L) between the shovel handle and the frame has 6 pits (I) with a diameter of 12mm; the working section (OR, MN) of the shovel handle and the connecting section (L) of the shovel handle and the frame adopt a circular arc transition Connection, blade portion (OR, FG) quenching treatment, the main function of described fitting curve QR is to bear the upturning of plow bottom soil furrow, the main function of curve PQ is the fragmentation of soil furrow, and the effect of curve OP is to make soil furrow again Crush and reduce surface soil disturbance; the tangential transition connection b...

Abstract

The invention discloses a fitting curve type subsoiler handle, and belongs to the field of tillage of agricultural machinery. The invention aims at designing a fitting curve type subsoiler handle which can significantly reduced tillage resistance and surface layer soil disturbance quantity via simulated analysis and optimal design. The fitting curve type subsoiler handle is composed of a shovel handle and rack connection segment (L), a shovel handle working segment (II), and a shovel handle and shovel tip connection segment (R), and is characterized in that the OP, PQ and QR segments of a shovel handle blade curve are separately formed by the following three fitting curve equations: y=-0.3845x<4>-700.4x<3>-4.785*10<10>x<2>-1.453*10<8>x-1.654*10<10>; y=8.951*10<5>x<5>-0.02656x<4>+3.148x<3>-186.2x<2>+5496x-6.52*10<4>; y=1.702*10<7>x<7>+1.718*10<5>x<6>+7.024*10<5>x<5>+0.01474x<4>+0.1653x<3>+0.944x<2>+2.342x-442.6. An inner directrix (FG) of the shovel handle working segment and an outer directrix (MN) of the shovel handle working segment are accordant with the blade curve; and a height of the OR and MN is H0. A cutting blade angle (alpha), a penetrating angle (w) and blade lines (BC, CD) are selected, so that the tillage resistance and the surface layer soil disturbance quantity can be effectively reduced, and the requirement of protective tillage is met.

Description

Technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a fitting curve type subsoiling shovel. Background technique [0002] Subsoiling is one of the core technologies of conservation tillage. After subsoiling the soil, it can break the hard plow layer, improve water use efficiency, reduce soil erosion, enhance water and soil conservation capacity, improve the growth environment of crop roots, and benefit the growth and development of crop roots. , thus greatly increasing the yield of root crops. The subsoiling shovel is a key component of the subsoiling machine. When the existing subsoiling shovel is used for subsoiling operations, there are often problems such as excessive tillage resistance and excessive disturbance of the surface soil of the cultivated land after subsoiling. Therefore, through the reasonable design and optimization of the structure of the subsoiler shovel, it is of great significance t...
