Background
The power rake is an implement for carrying out dry farmland soil breaking and soil preparing operation by utilizing a power output shaft of a tractor and driving a working part through a universal joint transmission shaft and a transmission system. Currently common power rakes can be generally divided into reciprocating power rakes, horizontal rotary power rakes and vertical rotary power rakes. The horizontal rotary power rake is widely applied to northern areas at present by combining the soil characteristics of China; compared with the traditional furrow plough, the power harrow has more thorough soil crushing effect; compared with the traditional rotary cultivator, the power rake has the advantages of deeper cultivated land depth and difficult hardening of soil.
The existing horizontal rotary power rake mainly comprises an upper shell and a lower shell of a gear box body, wherein mounting shaft holes of gear shafts are turned on the upper shell and the lower shell, a driving gear, a driven gear and corresponding gear shafts are mounted in the lower shell, then the upper shell and the lower shell are assembled, the mounting shaft holes of the lower shell of the upper shell are coaxially arranged, finally lubricating oil is injected into the gear box body, and friction loss among all meshing gears is reduced. Each gear shaft is connected with a vertical shaft rotor, and each rotor is provided with two vertical harrow blades (spike teeth). During operation, the rotor is driven by the power output shaft through the driving gear and the driven gear to transmit power, and the rotor rotates and advances to strike soil blocks so as to loosen and crush plough layer soil. The rotors of the power harrow are in a shape of a gate, and the gate-shaped planes of two adjacent rotors are mutually perpendicular, so that the working areas of any rotors are overlapped in a staggered way, and no harrow leakage area exists.
Aiming at the conventional horizontal rotary power rake, the inventor finds that the conventional horizontal rotary power rake drives a rotor and a rake blade to rotate by mutually meshing a plurality of gears, and the rake blade receives larger resistance in the soil loosening process, so that the larger resistance needs to be overcome between the gears for transmitting power, the stress between tooth surfaces of adjacent gears is increased, the friction between the mutually meshing gears and the friction between the gears and a gear shaft are further increased, the temperature of lubricating oil in a gear box body is increased, the conventional power rake lacks a heat dissipation device, heat cannot be dissipated in time, the viscosity of the lubricating oil is diluted due to the increase of the temperature of the lubricating oil, so that the lubricating oil is difficult to form an oil film on the tooth surfaces of the mutually meshing gears, the tooth surfaces of the mutually meshing gears collide with each other, the tooth beating phenomenon occurs, and finally each gear in the gear box body for driving the rake is worn, and the service life of the power rake is shortened.
