Walk-behind rotary tilling and harrowing machine for paddy field

Abstract

A walk-behind rotary tilling and harrowing machine for a paddy field relates to a machine used for rotary tilling and harrowing of a waterlogged paddy field, and mainly aims to solve the problem of dry soil tilling and harrowing of a conventional walk-behind rotary tiller for the paddy field. The walk-behind rotary tilling and harrowing machine comprises a frame, a gear shifting box, a diesel motor and a rotary tiller, wherein the gear shifting box is connected with the frame via a horizontal connection shaft; a hydraulic cylinder is located on a rotary tiller hanger on the frame; a rod of the hydraulic cylinder is connected with a U-shaped pull rod on the rotary tiller via a shaft; a hydraulic pump mounted on the frame is provided with an oil pipe connected with the hydraulic cylinder; a steering wheel, a driver seat, a walk-behind handle, steering handles, and gear shifting pull line control rods are arranged at the rear part of the frame; a control stick bracket is sleeved outside a gear shifting box gear shifting control stick; left-pulling and right-pulling gear shifting control sheets, as well as upper-pulling and lower-pulling gear shifting control sheets are arranged in the control stick bracket; and each gear shifting control sheet is provided with a gear shifting pull line connected with one steering handle and a spring connected with the control stick bracket. The walk-behind rotary tilling and harrowing machine has the advantage that rotary tilling and harrowing can be synchronously completed.

Description

Technical field: [0001] The invention relates to a device for raking the soaked paddy fields. Background technique: [0002] The existing paddy field walking rotary tiller can only plow (rotate) the land dryly, and then harrow the land after soaking in water. The two operations are labor-intensive and oily, and because the rotary tiller is installed on the walking wheels and steering of the walking tractor Between the wheels, the four corners of the paddy field cannot be raked, and manual raking is required, which is time-consuming and laborious. In addition, when the ridge is transferred from one rice pond to another, the rotary tiller cannot be lifted high enough to scrape the ridge; when it is turned dry, the rice stubble is broken up, and when the water comes in, it floats on the water surface, so as to prevent it from crushing the seedlings. It needs to be salvaged by hand. When it is turned over by drought, most of the grass seeds will not germinate and grow grass. Af...

[0002] The existing paddy field walking rotary tiller can only plow (rotate) the land dryly, and then harrow the land after soaking in water. The two operations are labor-intensive and oily, and because the rotary tiller is installed on the walking wheels and steering of the walking tractor Between the wheels, the four corners of the paddy field cannot be raked, and manual raking is required, which is time-consuming and laborious

In addition, when the ridge is transferred from one rice pond to another, the rotary tiller cannot be lifted high enough to scrape the ridge; when it is turned dry, the rice stubble is broken up, and when the water comes in, it floats on the water surface, so as to prevent it from crushing the seedlings. Manual salvage is required. During dry plowing, most of the grass seeds will not germinate and grow grass. After water comes in, germinate and grow grass will easily become wasteland.
