Description

Technical Field

[0001] The present application relates to the technical field of drying bins, and in particular to a drying bin for agricultural products. Background Art

[0002] Agricultural products refer to primary products from planting, forestry, animal husbandry and fishery, that is, plants, animals, microorganisms and their products obtained in agricultural activities, such as rice, sorghum, peanuts, corn, wheat and local specialties of various regions. Among them, rice usually contains high moisture after harvesting, so it is necessary to dry the wet rice (the raw material of rice) to reduce the moisture content to a suitable level, so as to ensure the quality and storage stability of rice.

[0003] Chinese patent authorization announcement number: CN220852856U discloses an internal circulation grain drying bin. This solution designs the drying tubes as a serpentine structure and the number is four, so that the drying tubes can be evenly distributed in the drying cylinder, and the hot air is diverted to the four groups of drying tubes through the guide plate. On the one hand, the temperature on the surface of the drying tubes can heat the grain, and the contact area between the drying tubes and the grain is large. On the other hand, the hot air can be evenly applied to the gaps between the grains through the air guide holes, thereby effectively improving the drying effect and drying efficiency of the device and saving the energy consumption of the device.

[0004] In the above scheme, the high-temperature gas enters the interlayer between the drying bin and the drying cylinder through the guide hole and is reabsorbed by the hot air blower through the circulation pipe, so that the heat energy is recycled. However, the hot air after drying contains a high humidity. When it is repeatedly recycled, the humidity will gradually accumulate. The air with high humidity cannot effectively take away the moisture in the grain. In addition, the air with high humidity will increase the load of the hot air blower, reduce its working efficiency, and affect the performance of the entire drying system, thereby resulting in a decrease in the drying effect.

[0005] Therefore, it is necessary to provide a drying bin for agricultural products to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Utility Model Content

[0011] Furthermore, the turntable is located between the upper mounting plate and the lower mounting plate, and the turntable is rotatably connected to the upper mounting plate and the lower mounting plate.

[0012] Furthermore, a motor is installed at the bottom of the lower mounting plate, and an output end of the motor passes through the lower mounting plate and is connected to the rotating plate.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] like Figure 1-5 As shown, the present application provides a drying bin for agricultural products, comprising: a drying bin body 1 and a drying mechanism 4, an inner cylinder 7 is installed inside the drying bin body 1, the inner cylinder 7 is fixed to the inner wall of the drying bin body 1 by welding, a plurality of air holes are opened on the outer wall of the inner cylinder 7, and an interlayer cavity is formed between the inner cylinder 7 and the drying bin body 1, a feeding pipe 3 connected with the inner cylinder 7 is installed at the bottom of the drying bin body 1, the feeding pipe 3 is fixed to the bottom of the drying bin body 1 by welding, and a valve is installed on the feeding pipe 3 for controlling the opening and closing of the feeding pipe 3, and a hot air blower 2 is installed on the side wall of the drying bin body 1, the hot air blower 2 is fixed to the outer wall of the drying bin body 1 by bolts, an air inlet pipe 9 connected with the inner cylinder 7 is installed at the air outlet of the hot air blower 2, and a connecting pipe 6 is installed at the air inlet of the air inlet pipe 9, an air outlet pipe 5 connected with the interlayer cavity is installed on the outer wall of the drying bin body 1, the drying mechanism 4 comprises an upper mounting plate 41, a lower mounting plate 42 and a rotating plate 43, The upper mounting plate 41 and the lower mounting plate 42 are both mounted to the side wall of the drying bin body 1, and are both fixed to the outer wall of the drying bin body 1 by welding. The upper mounting plate 41 is connected to the air outlet pipe 5, and the lower mounting plate 42 is connected to the connecting pipe 6. The upper mounting plate 41 can be fixedly connected to the air outlet pipe 5 by bolts, and the lower mounting plate 42 can be fixedly connected to the connecting pipe 6 by bolts. The air outlet pipe 5 is provided with a first through hole connected to the upper mounting plate 41, and the connecting pipe 6 is provided with a second through hole connected to the lower mounting plate 42, so that the dried gas can be smoothly discharged into the connecting pipe 6 through the air outlet pipe 5. A plurality of drying holes 48 are provided on the turntable 43, and a breathable plate 47 is installed inside the drying hole 48. The breathable plate 47 is fixed to the inner wall of the drying hole 48 by welding to provide support for the water-absorbing sponge 413, and a water-absorbing sponge 413 is installed on the top of the breathable plate 47.

[0032] In this embodiment, the present solution is a device for drying and dehumidifying agricultural products, preferably, for drying harvested rice to reduce the moisture content to a suitable level, thereby ensuring the quality and storage stability of the rice;

[0033] Specifically, the harvested rice is poured from the top of the drying bin 1 into the inner cylinder 7 through an external universal hoist, and the hot air blower 2 is controlled to work, and the generated hot air enters the inner cylinder 7 through the air inlet pipe 9 to heat and dry the rice in the inner cylinder 7. The dried gas enters the interlayer cavity through the air vents and is absorbed by the hot air blower 2 through the air outlet pipe 5 and the connecting pipe 6, so that the heat energy can be recycled. After the drying is completed, the dried rice can be discharged through the discharge pipe 3 by opening the valve outside the discharge pipe 3;

[0034] Among them, by arranging a drying mechanism 4 between the air outlet pipe 5 and the connecting pipe 6, since the hot air after drying contains a high humidity, the humid gas enters the drying hole 48 in the turntable 43 through the air outlet pipe 5, and the water-absorbing sponge 413 inside the drying hole 48 can absorb the water molecules in the gas, thereby achieving gas drying, improving the drying efficiency, and reducing the workload of the hot air blower 2. The dried gas is absorbed by the hot air blower 2 through the connecting pipe 6 for recycling.

[0035] It should be noted that the drying bin also includes a sealing cover detachably mounted on the top of the drying bin body 1. When drying is performed, the sealing cover is fixed to the top of the drying bin to ensure the drying effect.

[0036] like Figure 2 As shown, a guide plate 10 is installed at the bottom of the inner side of the drying bin body 1, and the guide plate 10 is fixed to the bottom of the inner cavity of the drying bin body 1 by welding. The air inlet pipe 9 is connected with the guide plate 10, and a plurality of drying pipes 8 connected with the guide plate 10 are installed on the top of the guide plate 10. The drying pipes 8 are also fixedly connected with the guide plate 10 by welding. The guide plate 10 is arranged in a ring shape and does not block the feeding work of the rice. The outer wall of the drying pipe 8 is provided with a plurality of air outlet holes.

[0037] In this embodiment, the hot air generated by the hot air blower 2 can enter the guide plate 10 through the air inlet pipe 9 for diversion, so that it enters multiple drying tubes 8. On the one hand, the temperature on the surface of the drying tubes 8 can heat the rice, and on the other hand, the hot air can be evenly applied to the gaps between the rice through the air outlet, thereby effectively improving the drying effect and drying efficiency.

[0038] like Figure 2 As shown, a plurality of drying tubes 8 are arranged in a spiral shape inside the inner cylinder 7 .

[0039] In this embodiment, by arranging the drying tube 8 in a spiral shape, the contact area between the drying tube 8 and the rice in the inner cylinder 7 can be increased, thereby improving the drying effect.

[0040] like Figure 3-5 As shown, the turntable 43 is located between the upper mounting plate 41 and the lower mounting plate 42, and the turntable 43 is rotatably connected to the upper mounting plate 41 and the lower mounting plate 42. A motor 45 is installed at the bottom of the lower mounting plate 42, and the motor 45 is fixed to the bottom of the lower mounting plate 42 by bolts. The output end of the motor 45 passes through the lower mounting plate 42 and is connected to the turntable 43. The output end of the motor 45 is fixedly connected to the turntable 43, so that the turntable 43 is driven to rotate by the motor 45. A rotating shaft 49 is rotatably connected inside the plurality of drying holes 48. One end of the rotating shaft 49 passes through the turntable 43 and is installed with a gear 411. The gear 411 is fixedly sleeved on the outer wall of the rotating shaft 49. An incomplete gear ring 44 meshing with the gear 411 is installed on the outer wall of the lower mounting plate 42 through a bracket, and both ends of the bracket are welded. The incomplete gear ring 44 is a 1 / 4 gear ring structure, and the inner walls of the multiple drying holes 48 are slidably connected with the extrusion disk 412. The multiple extrusion disks 412 are provided with a plurality of evenly distributed reserved holes to ensure that the gas can smoothly pass through the drying holes 48. The extrusion disk 412 abuts against the water-absorbing sponge 413. A pair of cams 410 are installed on the outer wall of the rotating shaft 49. The cam 410 is fixedly sleeved on the outer wall of the rotating shaft 49, and the cam 410 abuts against the top of the extrusion disk 412. A drainage hole 46 is provided on the lower mounting plate 42. The position of the drainage hole 46 corresponds to the position of the incomplete gear ring 44, that is, the moisture generated by the compression of the water-absorbing sponge 413 by the cam 410 can be smoothly discharged through the drainage hole 46.

[0041] In this embodiment, since the water-absorbing sponge 413 has a porous structure, it will be in a saturated state after absorbing moisture for a long time, which will lead to a decrease in the moisture absorption capacity. The turntable 43 can be controlled to rotate by starting the motor 45, so that the multiple drying holes 48 are coaxially arranged with the air outlet pipe 5 and the connecting pipe 6 in sequence. When the turntable 43 rotates, the multiple gears 411 can mesh with the incomplete gear ring 44 in sequence, thereby forcing the rotating shaft 49 and the cam 410 of the outer wall to rotate, thereby repeatedly squeezing the water-absorbing sponge 413. Since the water-absorbing sponge 413 has a certain elastic force, as the rotating shaft 49 rotates, the water-absorbing sponge 413 can be repeatedly compressed, thereby discharging the adsorbed water and discharging it through the drainage hole 46, thereby restoring the drying performance of the water-absorbing sponge 413 and ensuring that it continuously and effectively absorbs moisture.

[0042] It should be noted that during the rotation of the turntable 43, when the drying holes 48 opened on the turntable 43 are misaligned with the air outlet pipe 5 and the connecting pipe 6, the air outlet pipe 5 and the connecting pipe 6 are closed by using the unopened part of the turntable 43, so that the transportation of hot air can be temporarily interrupted, thereby extending the residence time of the hot air in the inner drum 7 and further improving the drying efficiency.

[0043] It is worth noting that before the gear 411 meshes with the incomplete gear ring 44, the cam 410 does not compress the water-absorbing sponge 413, and after the gear 411 meshes with the incomplete gear ring 44, the cam 410 also does not compress the water-absorbing sponge 413, that is, the cam 410 will compress the water-absorbing sponge 413 only when the gear 411 is meshing with the incomplete gear ring 44.

[0044] In addition, the water-absorbing sponge 413 will release moisture only when the cam 411 is squeezed during operation. The incomplete gear ring 44 corresponds to the position of the drainage hole 46. Only when the gear 411 coaxial with the cam 410 engages with the incomplete gear ring 44, the water-absorbing sponge 413 will be squeezed, and the squeezing action of the water-absorbing sponge 413 is performed above the drainage hole 46, thereby ensuring that the moisture released by the squeezing action of the water-absorbing sponge 413 can fall into the drainage hole 46 for discharge. On the contrary, when the position of the water-absorbing sponge 413 covers and completely overlaps with the connecting tube 6, the gear 411 coaxial with the cam 410 will not engage with the incomplete gear ring 44, the water-absorbing sponge 413 will not be squeezed, and therefore the moisture will not be discharged through the connecting tube 6.

[0045] Working principle:

[0046] The harvested rice is poured from the top of the drying bin 1 into the inner cylinder 7 through an external universal hoist, and the hot air blower 2 is controlled to work, and the generated hot air enters the inner cylinder 7 through the air inlet pipe 9 to heat and dry the rice in the inner cylinder 7. The dried gas enters the interlayer cavity through the air vents and is absorbed by the hot air blower 2 through the air outlet pipe 5 and the connecting pipe 6, so that the heat energy can be recycled. After the drying is completed, the dried rice can be discharged through the discharge pipe 3 by opening the valve outside the discharge pipe 3. A drying mechanism 4 is provided between the air outlet pipe 5 and the connecting pipe 6. Since the hot air after drying contains a high humidity, the humid gas enters the drying hole 48 in the turntable 43 through the air outlet pipe 5, and the water-absorbing sponge 413 inside the drying hole 48 can absorb the water molecules in the gas, thereby achieving gas drying. Drying improves drying efficiency and reduces the workload of the hot air blower 2. The dried gas is absorbed by the hot air blower 2 through the connecting pipe 6 for recycling. The turntable 43 can be controlled to rotate by starting the motor 45, so that the multiple drying holes 48 are coaxially arranged with the air outlet pipe 5 and the connecting pipe 6 in sequence. When the turntable 43 rotates, the multiple gears 411 can mesh with the incomplete gear ring 44 in sequence, thereby forcing the rotating shaft 49 and the cam 410 of the outer wall to rotate, thereby repeatedly squeezing the water-absorbing sponge 413. Since the water-absorbing sponge 413 has a certain elastic force, as the rotating shaft 49 rotates, the water-absorbing sponge 413 can be repeatedly compressed, thereby discharging the adsorbed water and discharging it through the drainage hole 46, thereby restoring the drying performance of the water-absorbing sponge 413 and ensuring that it continuously and effectively absorbs moisture.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
