Automatic excrement drying machine

Abstract

The automatic excrement drying machine comprises a drying barrel and a hot air supply device connected to the front portion of the drying barrel, a feeding port is formed in the front portion of the drying barrel, a discharging port and an exhaust port are formed in the rear portion of the drying barrel, and a drying shaft driven by a power device is rotationally connected into the drying barrel. An inner ventilation cavity which extends in the axial direction and supplies hot air to the drying shaft through a hot air supply device is formed in the drying shaft, a plurality of drying discs which communicate with the inner ventilation cavity and are arranged at intervals in the axial direction of the drying shaft are connected to the drying shaft, and each drying disc is provided with an exhaust cavity communicating with the inner ventilation cavity. The drying disc is provided with at least one air outlet capable of exhausting hot air into the drying barrel, the drying disc and/or the drying shaft, and the drying barrel is connected with an operation sweeping device capable of sweeping the inner cavity wall of the drying barrel and driving excrement to move backwards at the same time. The drying device has the advantages of being good in drying effect, high in drying efficiency and capable of avoiding adhesion and blockage and effectively protecting the environment.

Description

technical field [0001] The invention belongs to the field of excrement drying in animal husbandry, and particularly relates to an automatic excrement dryer. Background technique [0002] With the development of the economy, livestock are mostly raised on a large scale. When livestock are raised on a large scale, the livestock produces a large amount of manure, which needs to be cleaned up in time, otherwise it will affect the living environment of the livestock and affect the growth of the livestock. In addition, after timely cleaning and collection of these livestock manures, timely and effective treatment is required, otherwise environmental health will be affected. Especially with the great development of the cattle industry (such as cow dung produced in the dairy industry), a large amount of cow dung cannot be processed in time, which will cause environmental pollution. [0003] The existing main treatment methods of livestock manure include drying method and biologica...

Problems solved by technology

The disadvantage of the structure of the above dryer is that, since livestock manure generally has high viscosity, the manure is easy to adhere to the conveyor belt or the drum during the drying process, and the manure is i
