The utility model discloses a kind of drying device for wheat processing, it is related to the technical field of wheat processing drying, including base, the base top center is fixed with support pile, the support pile both sides are equipped with two load-bearing frames distributed in up and down, load-bearing frame inside is movably equipped with drying frame, same side two load-bearing frame between the same adjustment component is equipped with, for adjusting the distance between two drying frames, the adjustment component includes two L type limit rods, two L type limit rods are respectively arranged in bottom load-bearing frame front and back two sides, the front and back two sides of bottom load-bearing frame are all provided with sliding slot. The utility model moves by lifting and pulling top load-bearing frame and drives drying frame to move together, so that telescopic rod is stretched to support it, to realize the relative displacement between two load-bearing frames, it is convenient to adjust the distance between relative drying frame, avoid shading sunlight and ventilation effect, realize sufficient drying, improve drying effect and convenience.

The utility model relates to a ventilation pipeline and a ventilation assembly, comprising a ventilation pipe, at least one end of which forms an inclined port; the sealing cover is arranged at the inclined port of the ventilation pipe; the sealing cover is tightly attached to the inclined end opening of the ventilation pipe based on gravity. Due to the structure that the sealing cover is tightly attached to the inclined end opening of the ventilation pipe based on gravity, the ventilation pipe can be accurately opened according to the specific conditions of different areas in the farm, such as density distribution, temperature difference and humidity change of animals. The problem that in the prior art, due to the fact that all ventilation pipes are opened, ventilation of partial areas is excessive or insufficient is solved, the ideal ventilation effect is achieved, and more suitable environmental conditions are provided for a farm.

This invention discloses a composting method and intelligent composting system based on garden waste. The composting method based on garden waste provides a homogeneous and optimized material basis for efficient fermentation through intelligent pretreatment and dynamic formulation of raw materials. During fermentation, a three-dimensional sensor network is deployed and a synchronized digital twin model is constructed. The model is used to predict the future evolution of internal temperature, oxygen, and microbial activity within the compost pile. The degree of composting is intelligently determined by a multi-source information fusion model. The matured material undergoes multi-stage screening to produce a series of products, and a unique traceability code links the entire process to a digital archive, achieving quality traceability. This invention also provides an integrated system for implementing this method. This invention achieves predictive intelligent control and clean production in the composting process, significantly improving processing efficiency, product quality, and resource utilization, while effectively controlling operating costs and environmental pollution.

The utility model discloses a grain sliding pipe in a silo, which is adjustable in grain falling position and height and has a silo flattening effect, and relates to the technical field of grain storage. The grain sliding pipe in the silo comprises a main grain sliding pipe embedded in the upper conical cage section of the multi-channel ventilation column and a plurality of branch grain sliding pipes obliquely inserted and fixed to the upper end of the main grain sliding pipe in the circumferential direction, and the branch grain sliding pipes are automatically opened and closed through valves. By means of the multi-opening grain falling device, multi-opening grain falling can be carried out in the grain warehousing process, the falling position and height can be adjusted and controlled at any time, and the current situations of accumulation, grading, crushing and the like in the grain warehousing process are greatly improved. Due to the fact that multi-opening grain falling has the bin flattening function, the manual bin flattening workload can be greatly reduced, a large amount of manpower and material resource consumption is reduced, the warehousing cost is reduced, the grain feeding continuity is guaranteed, and the grain warehousing efficiency is greatly improved; meanwhile, along with the improvement of the current situations of grain accumulation, grading, crushing and the like, adverse effects on later-stage grain ventilation and fumigation can be avoided, and the stability of grain storage quality is ensured.

This utility model discloses a gravel material moisture content evaporation test chamber, including an outer chamber and an inner chamber disposed within the outer chamber. Both the outer and inner chambers are open-top, lidless boxes. The side and bottom plates of the outer chamber are not perforated, while the side and bottom plates of the inner chamber are evenly provided with multiple evaporation holes. Gaps are formed between the side and side plates of the outer and inner chambers, and between the bottom plates of the outer and inner chambers, to create an interstitial space. The thickness of the gap is not less than the maximum particle size of the gravel material. This utility model facilitates the evaporation of moisture content from the gravel material by evenly providing multiple evaporation holes on the side and bottom plates of the inner chamber. The absence of perforations on the side and bottom plates of the outer chamber prevents the simulated environment of the gravel material inside the inner chamber from being directly exposed to the atmosphere. The interstitial space between the outer and inner chambers allows for the filling of gravel material into the interstitial space during the test, thus synchronizing the evaporation state of the gravel material in the inner chamber with that of the actual gravel material across its entire cross-section.
