Description

Technical Field

[0001] This utility model relates to the technical field of fumigation devices, specifically a low-temperature grain depot circulating fumigation device. Background Technology

[0002] Grain fumigation is a specialized process that uses chemical agents such as aluminum phosphide to produce highly toxic phosphine gas, thereby killing pests in stored grains. Low-temperature grain fumigation equipment is crucial for ensuring the safe storage of grain in a low-temperature environment. During grain storage, pest and microbial infestation is one of the main reasons for the decline in grain quality and quantity. Low-temperature grain depots inhibit the growth and reproduction of pests and microorganisms by controlling temperature, but low temperature alone cannot completely eliminate their threat. Therefore, circulating fumigation technology has emerged. This technology introduces fumigation gas into the grain depot, utilizing the diffusion and penetration of the gas to kill pests and microorganisms in the grain.

[0003] Existing fumigation equipment often lacks effective turning of the grain during the fumigation process, making it difficult for the fumigation gas to penetrate deep into the grain pile. This is especially true for grains with thicker and denser piles, where the fumigation effect is greatly reduced. This also results in uneven gas distribution in the fumigation equipment, leading to significant differences in the fumigation effect on grains in different areas of the grain depot. In some areas, the gas concentration may be insufficient to effectively kill pests and microorganisms, which not only affects the overall fumigation effect but also prolongs the fumigation time, resulting in low efficiency. Utility Model Content

[0004] This invention provides a low-temperature grain depot circulating fumigation device. Gas is transmitted through a transmission pipe, then through a connecting pipe, and finally through a nozzle into the grain depot body. The gas is then evenly distributed within the grain depot body through a protective net. Simultaneously, a fixed motor drives a rotating synchronous wheel, which, through a synchronous belt, drives a connecting rod. The connecting rod, in turn, drives a fixed synchronous wheel, which, through the synchronous belt, drives a rotating pipe and stirring blades, thus agitating the grain. Combined with the even distribution of gas within the grain depot body through the protective net, this allows for uniform fumigation of the grain, improving both the fumigation effect and efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature grain depot circulating fumigation device, comprising: a grain depot body; a support plate fixedly connected to the inner wall of the grain depot body; and a fumigation mechanism, the fumigation mechanism comprising a transmission component, six sets of stirring components, two sets of transmission components, and a power component, each set of stirring components being disposed on the support plate, the transmission component being disposed on the grain depot body and the stirring component, each set of transmission components being disposed on the stirring component, and the power component being disposed on the transmission component.

[0006] Furthermore, each set of stirring components includes a rotating tube, multiple protective nets, and multiple stirring blades. One end of the rotating tube rotates through the bottom of the support plate. Both sides of each protective net are fixedly embedded in the outer surface of the rotating tube. One end of each stirring blade is fixedly connected to one side of the outer surface of the rotating tube.

[0007] Furthermore, the transmission component includes a fumigation machine body, a transmission pipe, six connecting pipes, and multiple nozzles. The fumigation machine body is fixedly connected to the top of the grain depot body. One end of the transmission pipe is fixedly connected to the fumigation machine body. One end of each connecting pipe is fixedly connected to the transmission pipe, and one end of each connecting pipe passes through the top of the rotating pipe. The top of the rotating pipe is rotatably fitted onto the outer surface of the connecting pipe. One end of each of the multiple nozzles is fixedly connected to the outer surface of the connecting pipe.

[0008] Furthermore, each set of transmission components includes three transmission synchronous pulleys, two fixed synchronous pulleys, and two connecting rods. Each transmission synchronous pulley is fixedly sleeved on the outer surface of the rotating tube. Both ends of each connecting rod are rotatably connected between the grain depot body and the support plate. Each fixed synchronous pulley is fixedly sleeved on the outer surface of the connecting rod, and each fixed synchronous pulley is mutually transmitted with the three transmission synchronous pulleys through a synchronous belt.

[0009] Furthermore, the power component includes two mounting synchronous pulleys, a fixed motor, and a rotating synchronous pulley. Each mounting synchronous pulley is fixedly sleeved on the outer surface of the connecting rod. The fixed motor is fixedly connected to the lower inner wall of the support plate. The rotating synchronous pulley is fixedly sleeved on the output end of the fixed motor, and the rotating synchronous pulley and the two mounting synchronous pulleys are mutually driven by a synchronous belt.

[0010] This utility model provides a low-temperature grain depot circulating fumigation device. It has the following beneficial effects: The low-temperature grain depot circulating fumigation device transmits gas through a transmission pipe via the fumigation machine body, then through a connecting pipe, and finally through a nozzle into the grain depot body. The gas is then evenly distributed within the grain depot body through a protective net. Simultaneously, a fixed motor drives a rotating synchronous wheel to rotate. Through the transmission of a synchronous belt, the mounting synchronous wheel drives the connecting rod to rotate, which in turn drives the fixed synchronous wheel to rotate. Through the transmission of the synchronous belt, the transmission synchronous wheel drives the rotating pipe and stirring blades to rotate, thus agitating the grain. Combined with the even distribution of gas within the grain depot body through the protective net, this allows for uniform fumigation of the grain within the grain depot body, improving the fumigation effect and efficiency.
