Straw burning and fertility improving machine

Abstract

The invention discloses a straw burning and fertility improving machine, and relates to an agricultural machine. The straw burning and fertility improving machine comprises a walking system and a tilling system which move forwards together; the tilling system comprises a rack, a break shovel installed at the foremost end of the rack, a rotary tilling device and a ridging device, wherein the rotary tilling device and the ridging device are sequentially installed behind the break shovel; a straw burning device is further installed on the rack and comprises a burning chamber, a material inlet hopper, a feeding device and a smoke exhaust pipe; the burning chamber is provided with an air inlet and a feed opening, and multiple ash leakage holes are formed in the bottom of the burning chamber; the material inlet hopper and the feed opening are in butt joint, and the smoke exhaust pipe is communicated with the burning chamber; the break shovel is of a hollow structure and is provided with multiple smoke outlet holes, and the smoke exhaust pipe is communicated with the break shovel. According to the straw burning and fertility improving machine, straw burning can be achieved when tilling is conducted, and straw ash can be evenly scattered in soil; meanwhile, heat obtained during straw burning can be used for conducting sterilization and deinsectization on the soil, so that the use value of straw is improved, and the soil fertility loss is reduced.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a straw burning machine for fertilizing. Background technique [0002] At present, the utilization of straw has received widespread attention, especially the effect of straw on soil fertility is remarkable, and it has been a joint research project in the world. Most agriculturally developed countries in the world attach great importance to the combination of land use and nutrition and the development of ecological agriculture. Most agriculturally developed countries adopt the technology of straw returning to the field, and straw returning to the field is very common in the United States. However, due to technical limitations, most areas in my country currently burn straw directly, and then let the ashes scatter in the soil for use as inorganic fertilizers. However, because the straw piles are burned in the same place, they cannot be evenly dispersed in the soil, It is of little signific...

Problems solved by technology

However, due to technical limitations, most areas in my country currently burn straw directly, and then let the ashes scatter in the soil for use as inorganic fertilizers. However, because the straw piles are burned in the same place, they cannot be evenly dispersed in the soil, Little significance; after straw burning, a large amount of ashes and smoke drift into the air, thus causing pollution; and because of a large amount of heat loss during straw burning, it is also extremely wasteful
