Power-driven rake

Abstract

The invention discloses a power-driven rake, which comprises a gear box, a plurality of rake groups, a traction frame, a reduction gearbox, a soil compacting and leveling device and a wheel mark scarifier, a cross beam is fixedly connected with the gear box, the reduction gearbox is arranged at the top end of the gear box, the gear box comprises a plurality of groups of gears and rake tooth shafts which are arranged side by side and are meshed with each other, a rake tooth seat is arranged at the lower end of each rake tooth shaft, rake teeth are fixed on the rake tooth seat, the gears drive the rake tooth shafts, the rake tooth seats and the rake teeth to rotate, the wheel mark scarifier is arranged at the front end of the gear box, the soil compacting and leveling device is arranged at the rear end of the gear box, after rake teeth crush soil, concave parts of the soil are filled with front soil leveling bars, primary soil leveling is carried out, then compacting rollers are used for soil compaction and soil moisture conservation, finally, a rear soil leveling plate device is used for secondary leveling, the soil leveling effect is good after operation, and only one-time operation is needed.

Description

technical field [0001] The invention relates to a land preparation tool with a driven rotary working part, in particular to a power-driven rake. Background technique [0002] The power-driven harrow refers to the machine tool that uses the power output shaft of the tractor to drive the working parts through the universal joint transmission shaft and the transmission system to perform soil preparation operations in dry fields. The main working part is a row of rake tooth shafts, and the lower end of each rake tooth seat shaft is provided with a rake tooth seat, and the rake tooth seat is equipped with two rake teeth. When working, the rake tooth shaft is driven by the power output shaft through the transmission system. While rotating, it moves forward and hits the soil block to loosen the soil in the cultivated layer.

Problems solved by technology

[0003] The authorized announcement number is CN208783177U, and the prior art with the patent title of "subsoiling power-driven rake" discloses a subsoiling power-driven rake, which includes a traction frame installed on a gear box, and a gearbox is installed on the top of the gear box. The gear box is provided with a group of interconnected gears and the rake tooth shaft. The lower end of the rake tooth shaft is provided with a rake tooth seat. At least two rake teeth are installed on each rake tooth seat. The gears are connected with the output gear of the gearbox. ;When working, the gearbox is driven by the input shaft of the gearbox. The output gear of the gearbox in the gearbox rotates to drive the gear installed on the rake teeth seat to rotate, and the rotation of the gear drives the rake teeth to rotate at high speed; Earthenware, the rear end of the gear box is equipped with a pressure roller, but there is no leveling device, resulting in poor soil flatness after one operation, which cannot meet the needs of farmers.
