Description

Technical Field

[0001] The present invention relates to the technical field of drying treatment, and particularly to a blowing type heating and sterilization mechanism for a grain storage device. Background Art

[0002] When storing grains using a grain storage device, in order to prevent the reproduction of microorganisms such as bacteria and molds attached to the grains during storage and extend the storage period of the grains, hot air generated by a hot air blower is usually used to blow and heat the grains to achieve the drying and sterilization treatment of the grains.

[0003] However, when using a hot air blower to heat and sterilize grains, since the hot air blower is mostly fixedly installed at a fixed position in the grain storage device, the generated hot air is difficult to be evenly distributed in the grain storage device, resulting in the grains near the hot air outlet having too high a temperature while the grains far from the hot air outlet having a relatively low temperature. This not only affects the heating and sterilization effect on the grains, but also extends the heating time of the hot air blower to achieve the expected sterilization effect, increasing energy consumption and storage costs while also affecting the heating and sterilization efficiency of the grains.

[0035] The specific usage method and function of this embodiment: When the present invention is in use, grains enter the upper end of the loading mechanism. After starting the hot air blower 2, the hot air blows and sterilizes the grains. During the process of drying and sterilizing the grains, the heating auxiliary pipe 201 is used in cooperation with the Venturi tube principle to improve the flow velocity of the hot air towards the grains; when starting the driving motor to rotate the driving support shaft 4, the first transmission gear 501 and the second transmission gear 504 push the transmission gear ring 503 and the positioning support cylinder 502 to rotate. During the rotation of the positioning support cylinder 502 and the driving support shaft 4, the first driving bevel gear 506 pushes the first driven bevel gear 507 and the pushing auxiliary shaft 5 to revolve around the driving support shaft 4 and turn up and down at the same time. The material pushing grid 508 realizes the pushing and mixing of the grains and turns up and down, and orderly and evenly pushes and turns over the grains at the upper end of the loading mechanism to the vicinity of the heating auxiliary pipe 201, so that the grains at each position at the upper end of the loading mechanism can be effectively and evenly heated.

[0036] Embodiment 2: On the basis of Embodiment 1, as Figures 7-9 shown: Among them, discharge guide grooves 301 are evenly arranged on the inner side of the load-bearing branch plates 3. The discharge guide grooves 301 are in a fan-shaped groove structure, and the positions between the upper and lower adjacent discharge guide grooves 301 are staggered; the two upper load-bearing branch plates 3 are fixedly connected to the inner wall of the device main body 1; the two lower load-bearing branch plates 3 are rotatably arranged with the device main body 1.

[0039] Among them, the material guiding control mechanism further includes: a second driving bevel gear 602 and a second driven bevel gear 603. The second driving bevel gear 602 is coaxially and fixedly connected to the inner end face of the driving auxiliary shaft 6; there are two second driven bevel gears 603, and the two second driven bevel gears 603 are respectively coaxially and fixedly connected to the inner end faces of the two transmission auxiliary shafts 601, and the second driving bevel gear 602 meshes with the second driven bevel gear 603.

During the rotation of the transmission auxiliary shaft 601, the driving gear 604 pushes the driving gear ring 605 and the lower bearing support plate 3 to rotate. When the positions of the upper and lower discharge guide grooves 301 are aligned, the grain at the upper end of the bearing mechanism slides down through the discharge guide groove 301 to the upper end of the separation mechanism. When the grain slides to the upper end of the separation mechanism and the driving motor continues to rotate, the discharge guide groove 301 of the bearing mechanism is in a closed state, while the discharge guide groove 301 of the separation mechanism is in an open state. The grain at the upper end of the separation mechanism then slides into the interior of the device main body 1. When the lower bearing support plate 3 rotates, it pushes the discharge support 304 to rotate synchronously.
