Miniature self-propelled ridger

Abstract

The invention relates to a miniature self-propelled ridger, belonging to the technical field of agricultural machinery. The ridger is composed of a power chassis, a ridge forming component and a ridge pressing component, wherein the power chassis is mainly composed of a frame with a traveling wheel and a traveling gear box; the ridge forming component is mainly composed of a support, a rotary cultivation gear box, a chain wheel box and rotary cultivation knife rollers; the power input shaft of the rotary cultivation gear box is in driving connection with the power output shaft of the traveling gear box; each rotary cultivation knife roller is composed of left and right symmetrical two segments respectively installed on horizontal power output shafts at two sides of the rotary cultivation gear box; the ridge forming component comprises two augers respectively installed on the horizontal power output shafts at two sides of the rotary cultivation gear box and located inside the two rotary cultivation knife rollers; and the maximum outside diameter of each auger is smaller than the enveloping outside diameter of the rotary cultivation knife rollers. The miniature self-propelled ridger provided by the invention can not damage sown seeds when used for ridge forming for planting potato and other crops, and is lower in power consumption during operation.

Description

technical field [0001] The invention relates to a soil ridging machine tool, in particular to a miniature self-propelled ridging machine with supporting power less than 7.5kW, belonging to the technical field of agricultural machinery. Background technique [0002] As far as the applicant knows, potatoes, sweet potatoes and tobacco leaves are the main dryland crops planted in the vast southwestern hilly and mountainous areas of China. The cultivation of these crops requires the soil to be arranged into ridges. Ridgers in the prior art are usually matched with small or medium-sized tractors with a power of more than 7.5kW. Although the ridging quality is good and the efficiency is high, the unit is large and heavy and has poor maneuverability. Used in fields or terraced fields. And the ridger that the existing technology is matched with the miniature power chassis of the pastoral management machine with power less than 7.5kW, although maneuverability is good, can work in sma...

AI Technical Summary

Problems solved by technology

[0003] One is to first plant potatoes or sweet potatoes into the ditch according to the agronomic requirements, and then use the ridging machine to gather the soil on both sides of the ditch to the middle to form a ridge on the ditch. The tiller will cut the seeds

[0004] The second is that due to the limitation of supporting power, the maximum ridge width of the current machine tool is about 0.7m, which cannot meet the requirement of about 1m ridge width for tobacco leaf planting.

[0005] The 3rd, the adhesive force of traveling wheel and ground is not enough when existing equipment operation, especially when walking on the loose soil surface of cultivated land, use existing rubber wheel and can produce serious skid phenomenon, and replace existing narrow iron wheel There will be a phenomenon of planing holes in situ, causing the machine tools to fail to work

[0006] To sum up, the existing miniature self-propelled ridgers with supporting power below 7.5kW cannot meet the ridging requirements for planting crops such as potatoes, sweet potatoes and tobacco leaves in small fields or terraces in hilly and mountainous areas.
