[0002] A grain pre-drying silo, often referred to as a "grain pretreatment silo" or "pre-cleaning tower," is a device used for preliminary cleaning and temporary storage of grain before it enters the drying system. It is mainly constructed of sturdy steel plates. The primary purpose of this facility is to ensure that impurities are removed from the grain before drying, improve drying efficiency, and protect the drying equipment from damage.
[0003] The pre-drying silo has a high internal structure, and all the grain is piled up inside. This causes excessive pressure on the bottom outlet valve, which can deform after long-term use, reducing its lifespan and affecting the smoothness of its opening and closing. Therefore, a pre-drying silo for grain storage is needed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a grain storage pre-drying silo to solve the problems mentioned in the background art, such as the silo body being too high and all the grain being piled up inside, resulting in excessive pressure on the bottom grain outlet valve, and after long-term use, the valve will deform, its lifespan will be reduced, and the smoothness of the valve opening and closing will be affected.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a grain storage and drying pre-drying silo, comprising:
[0007] A pre-drying chamber, comprising a chamber body and a ventilation pipe, wherein the ventilation pipe is welded to the top of the chamber body;
[0008] The damage prevention component includes a semi-circular baffle, a connecting frame, a first telescopic rod, a second telescopic rod, a servo motor, a rotating rod, and a stirring rod. The semi-circular baffle is hinged to the inner side wall of the chamber at its arc end. The connecting frame is fixed to the middle of the lower surface of the semi-circular baffle and the inner side wall of the chamber, respectively. The first telescopic rod is rotatably connected between the two connecting frames. The fixed end of the second telescopic rod passes through and is fixed to the side wall of the chamber, while its movable end is movably connected inside the chamber. The servo motor is fixed to the movable end of the second telescopic rod, the rotating rod is fixed to the output end of the servo motor, and the stirring rod is fixed to the rotating rod and is evenly distributed.
[0009] Furthermore, there are four semicircular baffles in total, with two baffles combined to form a complete circle, and each semicircular baffle corresponds to a set of servo motors below it.
[0010] Furthermore, the pre-drying chamber also includes a support frame and a first rain cover. The support frame is fixed to the lower section of the chamber body, and the first rain cover is movably connected to the top of the ventilation pipe.
[0011] Furthermore, it also includes a ventilation assembly, which includes a fixed plate and a third telescopic rod. The fixed plate is welded to the upper section of the ventilation pipe, the lower end of the third telescopic rod is fixed to the middle of the upper part of the fixed plate, and the lower end of the first rain cover is fixed to the top of the third telescopic rod.
[0012] Furthermore, the ventilation assembly also includes a support rod, a second rain cover, a first through hole, and a second through hole. The lower end of the support rod is fixed to the upper end of the outer ring of the first rain cover, the second rain cover is fixed to the top of the support rod, the first through hole is opened in the middle of the top of the first rain cover, and the second through hole is opened in the outer ring of the second rain cover.
[0013] Furthermore, the first through hole is higher than the second through hole, and when the third telescopic rod is retracted to the bottom, the lower edge of the first rain cover is lower than the top of the ventilation pipe.
[0014] Compared with existing technologies, the advantages of this utility model are:
[0015] I. This utility model, through the setting of anti-damage components, transports grain from the top of the silo into the silo body. After a portion accumulates at the bottom, the first telescopic rod is activated, extending and rotating around the connecting frame, causing the semi-circular baffle to rotate upwards. The two semi-circular baffles then merge, continuing to transport grain into the silo body. When both layers of semi-circular baffles are closed, the grain transport ends. The second telescopic rod then extends, driving the servo motor to move, causing the rotating rod and stirring rod to move to the middle of the silo body. The servo motor then starts, driving the rotating rod to rotate, which in turn drives the stirring rod to rotate, stirring the grain. This setting allows for segmented stacking of grain inside the silo body, reducing the pressure on the bottom valve.
[0016] II. In this utility model, through the ventilation component, when it rains or snows, the third telescopic rod above the fixed plate is activated, the second telescopic rod retracts, and the first rain cover moves downward, which in turn moves the second rain cover on the support rod downward. The first rain cover completely covers the top of the ventilation pipe inside. Rainwater and wind enter between the second rain cover and the first rain cover through the second through hole. Wind enters the compartment through the first through hole, and rainwater slides down the inclined surface at the top of the first rain cover. This design can prevent rainwater from entering the compartment and at the same time ensure ventilation inside the compartment to a certain extent. Attached Figure Description

[0031] The damage prevention component includes a semi-circular baffle 20, a connecting frame 21, a first telescopic rod 22, a second telescopic rod 23, a servo motor 24, a rotating rod 25, and a stirring rod 26. The semi-circular baffle 20 is hinged to the inner wall of the chamber 10 at the center of its arc end. The connecting frame 21 is fixed to the center of the lower surface of the semi-circular baffle 20 and the inner wall of the chamber 10, respectively. The first telescopic rod 22 is rotatably connected between the two connecting frames 21. The fixed end of the second telescopic rod 23 passes through and is fixed to the side wall of the chamber 10, while the movable end is movably connected inside the chamber 10. The servo motor 24 is fixed to the movable end of the second telescopic rod 23. The rotating rod 25 is fixed to the output end of the servo motor 24. The stirring rod 26 is fixed to the rotating rod 25 and is evenly distributed.
[0032] There are four semicircular baffles 20 in total. Every two baffles are combined into a complete circle, and each semicircular baffle 20 corresponds to a set of servo motors 24 below it.
[0033] The semi-circular baffle 20 provides support, the connecting frame 21 provides connection, the first telescopic rod 22 and the second telescopic rod 23 can change position, the servo motor 24 provides power, the rotating rod 25 is used to transmit power, and the stirring rod 26 can convert power.
[0034] Working principle:
[0035] Grain is conveyed from the top of the silo 10 into the silo 10. After a portion accumulates at the bottom, the first telescopic rod 22 is activated. The first telescopic rod 22 extends and rotates around the connecting frame 21, causing the semi-circular baffle 20 to rotate upward. The two semi-circular baffles 20 merge together, and grain continues to be conveyed into the silo 10. When both layers of semi-circular baffles 20 are closed, the grain conveying ends. The second telescopic rod 23 is activated and extends, driving the servo motor 24 to move, causing the rotating rod 25 and the stirring rod 26 to move to the middle of the silo 10. The servo motor 24 is activated, driving the rotating rod 25 to rotate, which in turn drives the stirring rod 26 to rotate, and the stirring rod 26 stirs the grain.
[0036] This step allows for segmented stacking of grain inside the storage compartment 10, reducing the pressure on the lowest valve.
[0037] Please see Figure 3-4 This embodiment, based on the above embodiments, further includes:
[0038] The ventilation assembly includes a fixed plate 30 and a third telescopic rod 31. The fixed plate 30 is welded to the upper section of the ventilation pipe 12, and the lower end of the third telescopic rod 31 is fixed to the middle of the upper end of the fixed plate 30. The lower end of the first rain cover 13 is fixed to the top of the third telescopic rod 31.
[0039] The ventilation assembly also includes a support rod 32, a second rain cover 33, a first through hole 34 and a second through hole 35. The lower end of the support rod 32 is fixed to the upper end of the outer ring of the first rain cover 13, the second rain cover 33 is fixed to the top of the support rod 32, the first through hole 34 is opened in the middle of the top of the first rain cover 13, and the second through hole 35 is opened in the outer ring of the second rain cover 33.
[0040] The first through hole 34 is higher than the second through hole 35. When the third telescopic rod 31 is retracted to the bottom, the lower edge of the first rain cover 13 is lower than the top of the ventilation pipe 12.
[0041] The fixed plate 30 provides support, the third telescopic rod 31 allows for positional changes, the support rod 32 provides support, the second rain cover 33 provides protection, and the first through hole 34 and the second through hole 35 facilitate ventilation.
[0042] Working principle:
[0043] When it rains or snows, the third telescopic rod 31 above the fixed plate 30 is activated, the second telescopic rod 23 retracts, and the first rain cover 13 moves downward, which in turn moves the second rain cover 33 on the support rod 32 downward. The first rain cover 13 completely covers the top of the ventilation pipe 12 inside. Rainwater and wind enter between the second rain cover 33 and the first rain cover 13 through the second through hole 35. Wind enters the compartment 10 through the first through hole 34, and rainwater slides down from the inclined surface of the top of the first rain cover 13.
[0044] This step prevents rainwater from entering the chamber 10 while ensuring ventilation inside the chamber 10 to a certain extent.
