Hand stubble-cleaning return-to-field operation machine

Abstract

The invention provides a hand stubble-cleaning return-to-field operation machine. The operation machine comprises a power walking main machine and a stubble-cleaning assembly, wherein a transmission case in the power walking main machine is arranged on the front part of a machine frame; an engine is arranged on the rear part of the machine frame relative to the transmission case; a walking wheel axle is arranged on the lower part of the machine frame and is in transmission connection with a first output shaft of the transmission case; a ridge guide wheel and a bracket of the ridge guide wheel are arranged at the front end of the machine frame; and the stubble-cleaning assembly is arranged on an installation base, in front of the walking wheel axle, of the machine frame, and a second speed transmission output shaft of the transmission case is in reduction transmission connection with a stubble-cleaning hob shaft arranged in front of the walking wheel axle. The hand stubble-cleaning return-to-field operation machine has the technical advantages of low energy consumption, labor conservation, capability of cleaning stubbles on sloping fields and high safety.

Description

technical field [0001] What the patent application of the present invention relates to is agricultural farmland stubble removal operation tool, what particularly relates to is small-sized walk-behind type stubble removal operation tool. Background technique [0002] The existing small-scale agricultural machinery for stubble removal operation on arable land consists of a power walking main engine and a stubble removal assembly. The engine of the power walking main engine is fixed at the front of the frame, the gearbox is fixed at the rear of the frame, and the stubble removal assembly is connected by the gearbox. It is arranged at the rear of the power walking main engine, and another deceleration output shaft of the gearbox drives the walking wheels; the power walking main engine is usually a walking tractor, as disclosed in Chinese patent: CN201120053153.4 "a kind of walking tractor supporting stubble machine". The main technical problems in the existing technology are: 1...

Problems solved by technology

[0004] The technical scheme of the hand-held stubble removal and field operation machine disclosed in the patent application of the present invention, the heavy engine is installed at the rear of the frame relative to the gearbox, and the front of the gearbox creates conditions for the forward installation of the stubble removal assembly. Its advantages mainly include: The center of gravity of the whole machine is stable, and the stubble hob rotating at high speed is compared with the rear low-speed road wheel. The difference in the reverse driving force between the two and the ground actually forms a working state in which the front stubble is driven and the rear road wheel is supported stably. The power consumption is greatly reduced. Compared with the existing technology, the power of the existing hand-held stubble removal agricultural machinery is 15-18 horsepower. The actual configuration power of this technical solution only needs 8-10 horsepower. , This hand-held stubble removal and field operation machine can be driven by itself to walk and stubble removal operations. The labor force of the operation is greatly reduced, and it is very labor-saving. The technical solution overcomes the side-slip phenomenon of the machine when operating on slopes, realizes the technical effect of stubble removal operations on slopes, and can stably perform stubble removal operations on slopes with slope angles not greater than 23°; another main technical advantage of this technical solution is high safety, stubble removal The assembly is far away from the handle position, thereby solving the technical problem of potential safety hazards in the existing stubble removal agricultural machinery
