Strip seedbed preparation device

Abstract

The invention discloses a strip seedbed preparation device. The strip seedbed preparation device comprises a frame, a three-point hitch, a stubble blade shaft and a rotary blade shaft which are installed at the bottom of the frame, a plurality of stubble blade sets installed on the stubble blade shaft, and rotary blade combinations installed on the rotary blade shaft. One end of the stubble blade shaft is connected with a stubble blade shaft drive gear box. One end of the rotary blade shaft is connected with a rotary blade shaft drive gear box. A central gear box is connected with the stubble blade shaft drive gear box and the rotary blade shaft drive gear box. An alternative arrangement mode of stubble strip blade sets and seedbed strip blade sets is adopted, compared with a blade arrangement mode of all rotary blades, power consumption of the machine is reduced, all the blades are arranged according to a multi-section spiral arrangement mode to prevent soil from being delivered to sides, soil turnover is reduced, and the strip seedbed preparation device has effects of soil conservation, water retention and fertilizer conservation. According to a rear supporting plate at the rear end at the bottom of the frame, the soil at the seedbed strips is prevented from moving to stubble cleaning strips, thereby facilitating growth of the seeds.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a belt-shaped seed bed preparation device. Background technique [0002] Tilling machinery is a key link in agricultural production, and its plowing quality directly affects the growth quality of crops. Existing plowing and soil preparation machines include horizontal rotary tillers, vertical rotary tillers, share plows and disc plows, etc.; traditional rotary tillers are mainly in the full-rotation mode, which disrupts the fertility of the soil from bottom to top. Gradient changes the original good soil structure, and the ability of crop root stubble to fix soil decreases, resulting in soil compaction, decreased drought and waterlogging tolerance, reduced organic matter content, and deterioration of soil conditions; Working conditions, the soil fragmentation rate is low after vertical rotary tillers, conventional plows and disc plows are operated, w...
