Straw pulverizing and scattering machine with uniform feeding device

Abstract

The invention discloses a straw pulverizing and scattering machine with a uniform feeding device, and belongs to the field of agricultural equipment. The straw pulverizing and scattering machine comprises the uniform feeding device, a pulverizing roller device, a flow guiding and scattering device, a transmission device, a fixed cutter device and a machine shell. The uniform feeding device is arranged below a straw outlet in the tail of a combined harvester, and the pulverizing roller device is arranged on the lower edge of the tail of the combined harvester. A uniform feeding roller in the uniform feeding device can accelerate straw, borne by a straw receiving plate, at a straw outlet, and the problem of straw blockage is solved. The accelerated straw is evenly fed into the whole pulverizing work width of the pulverizing scattering machine under the flow guiding action of flow guiding plates different in angle. Due to the special shape design of a flail knife, the pulverizing roller device can generate strong wind power during high-speed rotation cutting of the straw, the straw discharging speed is increased, and the straw scattering width and the scattering uniformity are improved; the angle of the fixed cutter device is adjustable, accordingly, the most beneficial cutting angle of the straw is reached, the pulverizing effect is improved, and power consumption is reduced.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a straw crushing and spreading machine with a uniform feeding device. Background technique [0002] When rice is harvested, a large amount of straw will be produced. Mechanized straw crushing and returning to the field is currently the main way to deal with straw. Compared with straw incineration, straw returning to the field not only reduces air pollution, but also effectively improves the soil structure, increases soil organic matter, and fertilizes the soil. Soil fertility; nowadays, the technology of the straw returning throwing machine with the rear suspension of the grain harvester has been widely promoted and used. However, the straw throwing and returning machine assembled with the current harvester generally has the problems of easy blockage, poor uniformity of straw feeding, and uneven throwing after crushing. These problems have not yet been solved by correspondin...

Soil fertility; nowadays, the technology of the straw returning throwing machine with the rear suspension of the grain harvester has been widely promoted and used. However, the straw throwing and returning machine assembled with the current harvester generally has the problems of easy blockage, poor straw feeding uniformity, and uneven throwing after crushing. There is no corresponding technology to solve these problems
