Straw decomposing agent spreading device

Abstract

The invention provides a straw decomposition agent broadcasting device which comprises a material tank (1) and a discharge structure (2). A discharge through groove (4) is formed in the bottom of the material tank (1), the section of the discharge through groove (4) is in the shape of an elongated rectangle, a flow regulating structure (3) is rotatably arranged in the discharge through groove (4) and comprises flow regulating plates (3.1), circular barriers (3.2) and flow regulating buttons (3.3), the section of each flow regulating plate (3.1) is in the shape of a circular arc, the circular barriers (3.2) are connected with two ends of each flow regulating plate (3.1) and are limited at the discharge through groove (4), the circular arcs of the section surfaces of the flow regulating plates (3.1) are smaller than or equal to 90 degrees, the chord lengths of the circular arcs of the section surfaces of the flow regulating plates (3.1) are larger than the width of the section surface of the discharge through groove (4), the discharge structure (2) is a fan-shaped groove with a narrow upper portion and a wide lower portion, a plurality of fan blades (8) which are equidistantly distributed are arranged inside the fan-shaped groove, and the discharge through groove (4) is detachably connected with the discharge structure (2). The straw decomposition agent broadcasting device has the advantages of simple structure, convenience in use, low maintaining and running costs and particular applicability to broadcasting powdery straw decomposition agents.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a straw decomposing agent spreading device. Background technique [0002] Straw decomposing agent can quickly decompose and degrade organic waste such as straw into nitrogen, phosphorus, potassium and other nutrients needed for crop growth, and promote the decomposition of straw, increase the content of organic matter in the soil, and at the same time produce a large number of beneficial microorganisms, stimulate crop growth, and improve agricultural products quality. At present, accelerating the promotion and application of straw decomposing agents and the implementation of quick straw rot returning to the field are not only powerful measures to increase soil organic matter and improve soil fertility, but also an effective way to reduce the amount of chemical fertilizers, realize straw burning, and reduce environmental pollution. [0003] Most of th...

Problems solved by technology

However, this type of device is applied in a horizontal direction, and it is very easy to cause dust when the powdery fast rot agent is applied.

Generally speaking, the structure of the device is relatively complicated, and limited by the power supply conditions, it is more suitable for spreading granular straw decomposing agents, but not suitable for spreading powdered straw decomposing agents.
