Soil-crushing rotary tiller for deep plowing of rice field

Abstract

The invention discloses a soil-crushing rotary tiller for deep plowing of a rice field. The soil-crushing rotary tiller comprises a frame, wherein the upper surface of the frame is in fit connection with a first transfer case; the front side of the first transfer case is in fit connection with a first transmission shaft; the rear side of the first transfer case is successively provided with two second transmission shafts and a second transfer case; two sides of the second transfer case are respectively in fit connection with a third transfer case through a third transmission shaft; the lower side of each third transfer case is in fit connection with a driving rotating shaft; a group of driven rotating shafts is arranged between two driving rotating shafts; the driven rotating shafts are infit connection with the frame; a group of transmission belts is in fit connection with two driving rotating shafts; each transmission belt correspondingly matches with a driving rotating shaft and adriven rotating shaft; a group of cutters is fixedly arranged on each transmission belt; the front end of the frame is in fit connection with a group of depth-keeping wheels; a group of plows is arranged between the depth-keeping wheels and the driven rotating shafts; and the plows are in fit connection with the frame. The soil-crushing rotary tiller provided by the invention has the advantages ofreliable structure, good soil plowing effect, and capability of realizing highly-efficient and rapid leveling of a land.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a rotary tiller for deeply plowing rice fields. Background technique [0002] Existing rotary cultivators are mainly driven soil cultivating machines with rotating cutter teeth as working parts, also known as rotary cultivators, which have a strong ability to break soil and can be used for cultivation of shrub land, swamp land and grassy wasteland. But the existing rotary tiller has the following disadvantages: the existing rotary tiller is not suitable for paddy fields, and it is easy to form missing tillage under the transmission box. For the land with better integrity such as weed coverage, the existing rotary tiller The mechanical plowing depth is shallow, and the crushing effect is poor, and the overall energy consumption is relatively large, so it is difficult to achieve the expected plowing effect of the paddy field. Contents of the invention [0003] The...
