Stubble cleaning subsoiling fertilizer applying plowing combined operation machine

Abstract

The invention discloses a stubble cleaning subsoiling fertilizer applying plowing combined operation machine. The machine comprises a rack, a central reversing reduction gear box is arranged on the rack, a stubble cleaning device is arranged in front of and below the rack, a rotary tillage device is arranged on the portion, located behind the stubble cleaning device, of the rack, a subsoiler is arranged on the portion, between the stubble cleaning device and the rotary tillage device, of the rack, a fertilizer applying mechanism is arranged above the rack, and a compressing depth limiting roller is hinged to the back portion of the rack; two level output shafts, namely, an output shaft and a lower output shaft are arranged on the central reversing reduction gear box, the upper output shaftis in linkage with the stubble cleaning device through a side transmission gear box, the lower output shaft is in linkage with the rotary tillage device, and the compressing depth limiting roller isin linkage with the fertilizer applying mechanism. The machine integrates operation processes of stubble cleaning, subsoiling, fertilizer applying, soil compression and the like and takes the operation processes as integrated functions, is high in production efficiency and applicable to carrying out multiple operations on soil keeping stubbles before sowing, and avoids that the machine enters a land for operations many times so as to make field soil compacted through a tractor.

Description

technical field [0001] The invention belongs to soil plowing machinery among agricultural machinery, and in particular relates to a stubble removing subsoiling and rotary tillage combined operation machine. Background technique [0002] Before spring or autumn sowing of crops, the soil needs to be treated, including stubble removal, soil loosening, fertilization, rotary tillage, suppression and other operations, and the operation time is tight, so as to achieve the effect of competing for farming time. At present, these agronomic requirements are completed by machines with a single function. For example, subsoiling operations are completed by subsoilers, rotary tillage is completed by rotary tillers, and stubble removal is completed by stubble removers. Disadvantages of low efficiency, labor and time-consuming. With the continuous increase of the number of high-power tractors, the development of high-efficiency compound implements capable of completing the above multiple fu...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a stubble removing subsoiling and rotary tillage combined operation machine for the shortcomings of the single function of the machine tool in the prior art. The machine tool of the invention is suitable for soil finishing before the crops are sown, and can complete the stubble crops at one time. Root stubble crushing, deep loosening, fertilization, rotary tillage, compaction and other operating procedures have the characteristics of competing for farming time and moisture conservation. It is an efficient and multi-functional compound machine tool
