Description

Technical Field

[0001] The utility model relates to the technical field of granaries, in particular to a spliced ​​shallow round silo central pressure reducing pipe. Background Art

[0002] The central pressure reducing pipe of the shallow circular silo, with its unique design, plays a role in reducing pressure and buffering when grain falls from the top of the silo to the bottom, thereby preventing the grain from being broken due to high-speed impact. At the same time, it also has a ventilation function, which can assist in ventilation and heat dissipation in the central area of ​​the silo, improve ventilation effect, reduce the temperature difference between the inside and outside of the grain pile, and prevent grain from becoming moldy and infested with insects. The application of the central pressure reducing pipe of the shallow circular silo significantly reduces the grain breakage rate when entering the warehouse and reduces the impact of automatic grading on the quality of stored grain. At the same time, by improving the ventilation effect, the temperature difference between the inside and outside of the grain pile is reduced, effectively preventing the occurrence of problems such as grain mold and infestation of insects.

[0003] After searching, the Chinese patent application number CN214628250U discloses a ventilation and decompression center tube based on a shallow circular silo. Due to the differences in physical properties such as grain shape, particle size, surface state, density, and some impurities mixed in wheat, the grains are affected by different friction forces, airflow buoyancy, etc. during movement, which causes the automatic grading of the grain pile entering the silo. Impurities and broken grains are concentrated in the central area, resulting in a small porosity in the central area. During the ventilation and temperature equalization (cooling) process, the temperature around the grain pile drops quickly, while the center cools down slowly, resulting in prolonged ventilation time and increased ventilation energy consumption. The key is that there is a significant temperature difference between the inside and outside of the grain pile, which can easily cause condensation in the grain pile, and then cause problems such as mold and insects in the grain. Therefore, when the grain is entered, the grain falls on the first anti-breakage cone cap, and then slides to the bottom of the silo through multiple second anti-breakage cone caps, achieving buffering and preventing the grain from colliding and breaking, while preventing the automatic grading of the grain pile in the silo. At the same time, the central tube body and the through holes on it can assist in air supply to achieve air supply and heat dissipation from the central area of ​​the silo, thereby improving the ventilation effect.

[0004] During use, the above-mentioned central pressure-reducing pipe helps to cushion the falling grain and improves the ventilation effect. However, when installing the existing central pressure-reducing pipe, the pressure-reducing pipe is usually divided into different small sections for easy transportation. The pressure-reducing pipe is installed on site. When installing and splicing the pressure-reducing pipes at both ends, it is usually necessary to screw multiple bolts to fix the central pressure-reducing pipe, which is time-consuming and labor-intensive, reduces the installation efficiency, and also reduces the disassembly efficiency when the pressure-reducing pipe is damaged for repair and replacement.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] As attached Figure 1-5 As shown, the utility model provides an embodiment: a spliced ​​shallow silo central decompression pipe, comprising a central decompression pipe body 1, characterized in that one end of the central decompression pipe body 1 is fixedly connected to a splicing assembly;

[0033] The splicing assembly includes a splicing ring 2, which is fixedly connected to one end of the central decompression tube body 1, and a plurality of card slots 3 are opened on both sides of the splicing ring 2. The other end of the central decompression tube body 1 is fixedly connected to a splicing sleeve 4, and both sides of the splicing sleeve 4 are provided with mounting grooves 5. Both sides of the mounting groove 5 are provided with slide grooves 6. Both sides of the splicing sleeve 4 are provided with multiple through grooves 7. The internal rotation of the mounting groove 5 is connected with a two-way screw rod 8, and both ends of the two-way screw rod 8 are threadedly connected to a moving block 9. One side of the moving block 9 is fixedly connected to two plug rods 10, and both sides of the moving block 9 are fixedly connected to a slider 11. The slider 11 is slidably connected to the inside of the slide groove 6. The two-way screw rod 8 is fixedly connected to the knob 12 through the shaft rod. The card slot 3 is convenient for engaging with one end of the plug rod 10, and the moving block 9 is convenient for driving the movement of the two plug rods 10. The through groove 7 is used for the penetration of the plug rod 10. When the slider 11 slides in the inside of the slide groove 6, it is convenient to limit the moving slider 11.

[0034] As attached Figure 2 As shown, both sides of the central decompression pipe body 1 are provided with support assemblies, and the support assemblies include a reinforcing rod 13, the reinforcing rod 13 is hinged on both sides of the central decompression pipe body 1, and a plurality of first threaded holes 14 are opened on one side of the reinforcing rod 13, and a support rod 15 is slidably connected to the outside of the reinforcing rod 13, and a first bolt 16 is passed through one end of the support rod 15, and an adjustment block 17 is hinged to the other end of the support rod 15, and a second bolt 18 is passed through one side of the adjustment block 17. Both sides of the splicing sleeve 4 are fixedly connected with a support box 19, and a plurality of first threaded holes 14 are opened on one side of the support box 19. Two threaded holes 20, a reinforcing rod 21 is fixedly connected to the lower surface of the support box 19, one end of the two reinforcing rods 21 is fixedly connected to both sides of the central pressure reducing tube body 1, and the support rod 15 slides on the outside of the reinforcing rod 13, which is convenient for the installation of the adjustment block 17 and the contraction of the reinforcing rod 13.

[0035] Working principle: After transporting the central pressure reducing pipe body 1 of different sections to the site where splicing is required, the splicing ring 2 in the pipe body at one end is slidably inserted into the interior of the splicing sleeve 4, and then the knob 12 is turned. The knob 12 drives the bidirectional screw rod 8 to rotate through the shaft. When the bidirectional screw rod 8 rotates, under the action of the thread, the moving blocks 9 on both sides are driven to approach each other, so that the moving block 9 drives the slider 11 to slide inside the slide groove 6, thereby facilitating the movement of the slider 11. When the moving block 9 moves, it drives the two plug rods 10 on both sides to approach each other, so that the plug rod 10 passes through the through-slot 7 and is inserted into the interior of the card slot 3, thereby facilitating the splicing of the two sections of the pipe body and reducing the use of bolts.

[0036] After the splicing is completed, rotate the reinforcing rod 13, tighten the first bolt 16, and screw the first bolt 16 out of the corresponding first threaded hole 14 to facilitate releasing the limit of the support rod 15, and then slide the adjusting block 17 into the interior of the support box 19, and then slide the adjusting block 17 to the required position, so that the support rod 15 slides outside the reinforcing rod 13, and then screw the second bolt 18 through the adjusting block 17 and threadedly connect it with the second threaded hole 20, so as to facilitate the fixation of the adjusting block 17, and then screw the first bolt 16 into the interior of the corresponding first threaded hole 14 to facilitate fixing the position of the support rod 15, thereby strengthening the supporting effect on the spliced ​​pipe body.
