[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] The utility model provides Figure 1-Figure 5 The steel plate silo with cooling function shown in the figure includes a silo barrel 1, a support frame 5 is arranged at the bottom of the silo barrel 1, a main barrel cover 3 is arranged at the top of the silo barrel 1, a conveying pipe 6 is arranged in the middle of the silo barrel 1, a main rod 61 is arranged inside the conveying pipe 6, a main shaft 63 is arranged at the top of the main rod 61, a driving motor 8 is arranged at the top of the conveying pipe 6, the output shaft of the driving motor 8 is connected to the main shaft 63, a discharge pipe 7 is arranged on one side of the top of the conveying pipe 6, a spiral blade 62 is arranged on the outer wall of the main rod 61, and a protective plate 64 is arranged on the outer edge of the spiral blade 62; an exhaust assembly 9 is arranged on one side of the top of the main barrel cover 3, the exhaust assembly 9 includes an exhaust pipe 91, and the end of the exhaust pipe 91 is connected to the air guide pipe 93.
[0027] In this embodiment, specifically, the protective plate 64 is a soft structure, the inner edge of the protective plate 64 is in contact with the outer edge of the spiral blade 62, and the outer edge profile of the protective plate 64 is the same as the outer edge profile of the spiral blade 62; the protective plate 64 can be made of silicone-based rubber, which is a soft material with elasticity, and its specific structure has been disclosed in the prior art and will not be repeated here;
[0028] Specifically, the driving motor 8, the conveying pipe 6, the main rod 61, the spiral blade 62, and the main shaft 63 constitute a rice conveying mechanism, and the main shaft 63 is driven to rotate by the output shaft of the driving motor 8, and the main shaft 63 drives the main rod 61 and the spiral blade 62 to rotate. When the spiral blade 62 rotates, it stirs the rice in the silo 1 and conveys the rice upward. After the rice reaches the top of the conveying pipe 6, it is discharged from the discharge pipe 7. During the process of the spiral blade 62 driving the protective plate 64 to rotate, due to the elastic characteristics of the protective plate 64, the protective plate 64 will not cut the rice, which is beneficial to protecting the rice and avoiding the problem of rice being broken by cutting and squeezing.
[0029] like Figure 1-Figure 5 As shown, a filter element 92 is inserted into the exhaust pipe 91, and the inner walls of both ends of the air guide pipe 93 are provided with internal threads, and the air guide pipe 93 and the exhaust pipe 91 are screwed together by threads; it should be noted that an exhaust device can be connected to the end of the air guide pipe 93, and the exhaust device extracts the air in the silo 1 through the air guide pipe 93. In the process of stirring and transporting rice, the hot air in the silo 1 is extracted to the outside, which is conducive to the dissipation of heat and achieves the purpose of cooling;
[0030] Furthermore, under the filtering action of the filter element 92, the dust in the rice can be filtered out so that the external environment will not be polluted.
[0031] like Figure 1 and Figure 5 As shown, an air inlet pipe 11 is inserted into the interior of the silo 1 , the top end of the air inlet pipe 11 passes through the main tube cover 3 upward, and a threaded connecting pipe 10 is provided on one side of the top end of the air inlet pipe 11 .
[0032] In this embodiment, specifically, an external air duct is connected to the threaded pipe 10, and air is continuously input into the interior of the silo 1 through an external air supply device, so that the air inside the silo 1 is forced to circulate, which is conducive to the rapid dissipation of heat.
[0033] like Figure 1 and Figure 5As shown, an insert rod 12 is also inserted into the interior of the silo 1, and the top end of the insert rod 12 penetrates the main tube cover 3 upward, and the top end of the insert rod 12 is connected to a connecting block 121, and the end of the connecting block 121 is connected to a connecting plate 13, and a lifting cylinder 14 is provided at the bottom of one end of the connecting plate 13, and a fixing plate 15 is provided at the bottom of the lifting cylinder 14.
[0034] Specifically, the connecting plate 13 is driven up and down by the lifting cylinder 14, and the connecting plate 13 drives the connecting block 121 and the plug 12 to move up and down. The plug 12 moves up and down in the silo 1. When the silo 1 is filled with rice, the up and down movement of the plug 12 is conducive to loosening the rice inside the silo 1. Before transporting the rice, loosening the rice is conducive to the spiral blade 62 driving the protective plate 64 to stir the rice, avoiding the occurrence of stuck temperature, and making the initial operation of the drive motor 8 smoother.
[0035] like Figure 5 As shown, the bottom end of the silo 1 is a conical structure, and a positioning plate 16 is fixed inside the silo 1. A round tube is arranged in the middle of the positioning plate 16, and the delivery pipe 6 vertically passes through the round tube downward;
[0036] It should be noted that the conveying pipe 6 is vertically arranged inside the silo 1, and is also vertically conveyed during the process of conveying rice. The conveying pipe 6 is positioned and fixed by the positioning plate 16, which improves the stability of the conveying pipe 6, and a window can be opened on the side wall of the silo 1, and the window is used to convey rice into the interior of the silo 1.
[0037] like Figure 1 and Figure 5 As shown, a secondary cylinder 2 is further provided on one side of the silo 1, a secondary cylinder cover 4 is provided on the top of the secondary cylinder 2, an extended end of the discharge pipe 7 is connected to the secondary cylinder cover 4, a discharge hole (not shown in the figure) is provided on one side of the bottom end of the secondary cylinder 2, and a return hole 21 corresponding to the discharge hole is provided on one side of the bottom end of the silo 1;
[0038] Specifically, the rice passes through the discharge pipe 7 and enters the auxiliary cylinder cover 4, and then goes down into the auxiliary cylinder 2. The auxiliary cylinder 2 has a buffer space for storing the rice. When a part of the rice in the silo 1 is transported into the auxiliary cylinder 2, a certain space is vacated inside the silo 1. At this time, the rice in the auxiliary cylinder 2 passes through the discharge hole at the bottom under the action of its own gravity, and then enters the interior of the silo 1 through the return hole 21. The rice circulates inside the silo 1 and the auxiliary cylinder 2, which is beneficial to the air circulation inside the silo 1 and also beneficial to the diffusion of air between the rice, so as to achieve the purpose of cooling and heat dissipation.
[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
