The invention discloses agricultural straw treatment equipment, which comprises a shell, a base, a water box and a material inlet hopper, wherein the top portion of a crushing chamber is communicatedto the material inlet hopper, two sets of mutually-cooperating crushing cutter blades are installed in the crushing chamber, a stirring blade is fixed on a stirring shaft, the right end of an inclination plate is communicated to a sand-stone discharge pipe, the right side wall of a flotation chamber is provided with a material outlet, the material outlet is communicated to a fermenting chamber, aheating device is installed on the bottom portion of the fermenting chamber, the right side of a filtering screen is communicated to the water box, a water pump is communicated in the water box, the other end of the water pump is communicated to the flotation chamber, and the top portion of the shell is provided with a solar photovoltaic panel and a storage battery. According to the present invention, by arranging the water pump, the internal water is recycled; the straw is separated from the sand grain so as to ensure the fertilizer quality and conveniently achieve the fermenting treatment ofthe straw; with the heating device, the internal temperature of the fermenting chamber is constant so as to improve the production efficiency of the fertilizer; and the solar photovoltaic panel usessolar power to generate electricity so as to supplement part of the electric energy, such that the energy consumption is reduced, and the agricultural production cost is saved.
