Double-side output-type straw smashing returning machine capable of removing debris on earth surface

Abstract

The invention discloses a double-side output-type straw smashing returning machine capable of removing debris on the earth surface. The machine comprises a rack, a suspension rack, a transmission system, a straw smashing device, an auger conveying device, a limit roller and a discharging shell. An air plate is fixed between cutter bases of the straw smashing device; the direction of a left spiralblade of the auger conveying device is opposite to that of a right spiral blade of the auger conveying device; one or more rod-shaped or plate-shaped anti-blocking rods are fixed to the portions, corresponding to the two ends of an auger shaft of the discharging shell, of the auger conveying device; the discharging shell is located at the outer side of the rack. Compared with the prior art, the double-side output-type straw smashing returning machine has the advantages that when crop straw is smashed and returned to the field, stems and leaves which drop on the membrane can be effectively removed, the smashed straw is placed at the two sides of the membrane, and on the premise that it is guaranteed that the crop straw is returned to the field, a good operation condition can be created forresidual membrane recycle.

Description

technical field [0001] The invention relates to a straw crushing and returning machine used in conjunction with a tractor, in particular to a double-side output straw crushing and returning machine which can remove sundries on the ground, and belongs to the technical field of agricultural machinery. Background technique [0002] The crushing and returning of crop straws and the recycling of farmland residual film are two main tasks and problems faced by agricultural production at present and in the future. Compared with inland provinces and regions, due to its latitude and other reasons, Xinjiang has low temperature and short frost-free period. In order to increase temperature and moisture, suppress weeds, increase yield and improve quality, crops are generally planted with plastic film mulching technology. One year, it leads to the well-known white pollution problem. At present, the use of mechanical recovery of residual film is still a more realistic and economical method...

AI Technical Summary

Problems solved by technology

Most of the currently used straw crushing and returning machines do not have an auger conveying device. The crushed crop straw is directly sprinkled between the crop rows, or directly on the plastic film. When the residual film recovery machine is working, the residual film and The shredded straw will be put away together. Due to the limitation of the space of the film collecting box of the residual film recycling machine and the easy accumulation of the plastic film, the film collecting box will be full within a short distance (generally less than 500m)

At this time, it is necessary to stop and drive to the field. In this way, the straw cannot be fully returned to the field, and the efficiency of the residual film recycling machine will be affected.

However, the straw crushing and returning machine with the auger conveying device is mostly conveyed to one side, which is easy to cause congestion in the middle of the auger conveying device and at the discharge port, resulting in the broken straw falling between the crop rows, and also affecting the work. efficiency

Also due to the structure of the straw crushing device, the crushed straw cannot fully reach the auger conveying device, and will also be scattered among the crop rows in large quantities.
