Description

Technical Field

[0001] The utility model relates to the technical field of granaries, and more specifically, to a multifunctional crushing reduction central pressure reducing pipe. Background Art

[0002] The granary pressure reducing pipe, also known as the vent pipe or pressure reducing vent pipe, is an important device installed inside the granary. It is mainly used to adjust the air pressure and humidity to ensure the safe storage of grain.

[0003] 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 differently by friction, airflow buoyancy, etc. during movement, resulting in automatic grading of the grain pile entering the warehouse. 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 problems such as grain mildew and insects.

[0004] After searching, the Chinese patent with application number CN202120983747.9 discloses a ventilation and decompression central tube based on a shallow circular silo. The grain falls onto the first anti-crushing cone cap, and then slides to the bottom of the silo through multiple second anti-crushing cone caps, thereby buffering the impact and preventing the grain from colliding and breaking. At the same time, it prevents the automatic grading of the grain pile in the silo. At the same time, the main body of the central tube cooperates with the through holes on it to assist in the air supply to achieve air supply and heat dissipation from the central area of ​​the silo, thereby improving the ventilation effect.

[0005] When the above-mentioned ventilation and decompression center pipe based on the shallow circular silo is actually used, the general decompression pipe has poor flexibility in regulating the grain flow, which will cause uneven distribution of grain in the silo, resulting in grain piling up too high and too quickly, increasing the pressure on the silo roof and silo walls, thereby affecting the stability of grain storage. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a multifunctional crushing reduction central pressure reducing pipe to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A multifunctional crushing reduction center pressure reducing pipe comprises a pressure reducing pipe body installed inside a grain storage bin, and is characterized in that: a control box is installed on the upper surface of the pressure reducing pipe body, and a control assembly is installed inside the control box; the control assembly comprises a motor, and a first gear is installed at the output end of the motor, a toothed disc is engaged on one side of the first gear, a plurality of second gears are engaged on the inner side of the toothed disc, support rods are installed on the inner sides of the second gears, the interior of the second gears is rotatably connected to the outer side of the support rods, a rack is engaged on one side of the second gears, and an adjustment plate is fixedly connected to one end of the rack, and a plurality of slide grooves are provided on the inner side of the pressure reducing pipe body.

[0009] By adopting the above technical solution: the first gear is engaged to drive the toothed disc to rotate, so that the toothed disc can engage to drive multiple second gears to rotate, so as to drive the rack to move, so that the rack can drive the adjustment plate to slide inside the slide groove, and by adjusting the gap between the multiple adjustment plates, the grain discharge flow rate can be adjusted and controlled.

[0010] As a further description of the above technical solution: a plurality of support columns are fixedly connected to the outside of the pressure reducing tube body, a plurality of discharge ports are opened on the surface of the pressure reducing tube body, and a plurality of first buffer plates and second buffer plates are installed on the inside of the pressure reducing tube body.

[0011] By adopting the above technical solution: using multiple first buffer plates and second buffer plates evenly distributed inside the pressure reducing pipe body, the falling speed of the grain can be buffered and the breakage rate of the falling grain can be reduced.

[0012] As a further description of the above technical solution: the top of the pressure reducing tube body is connected to a discharge barrel, one side of the discharge barrel is connected to a central fan, one end of the central fan is connected to an air supply pipe, the other side of the discharge barrel is connected to a circulating fan, and one end of the circulating fan is connected to an exhaust pipe.

[0013] By adopting the above technical solution: air is supplied to the interior of the pressure reducing pipe body through the air supply pipe, and then the air inside the pressure reducing pipe body is discharged through the exhaust pipe, so that the air inside the grain storage bin can be kept circulating.

[0014] As a further description of the above technical solution: the outer side of the discharge barrel is connected to multiple diversion pipes, the inner sides of the multiple diversion pipes are connected to the first chute pipe and the second chute pipe, and the inner sides of the multiple first chute pipes and the second chute pipes are provided with multiple discharge ports.

[0015] By adopting the above technical solution: the grain inside the pressure reducing tube body can be diverted to multiple diversion tubes through the discharge barrel, and the grain can be evenly dispersed into the grain storage bin through multiple first chute tubes and second chute tubes.

[0016] Technical effects and advantages of this utility model:

[0017] 1. Compared with the existing technology, the control component is provided. The gear disc is rotated to engage with multiple second gears, which are then engaged with the rack to drive the adjustment plate to move. The gaps between the multiple adjustment plates are used to control the grain, ensuring that the grain enters the silo at an appropriate speed. This avoids the increase in pressure and breakage rate caused by excessive grain accumulation. At the same time, it can shorten the grain entry time and improve storage efficiency.

[0018] 2. By setting a discharge barrel, a diversion pipe, a first chute tube, a second chute tube and a discharge port, compared with the existing technology, the grain can be transported to multiple first chute tubes and second chute tubes through the discharge barrel, and then the grain can be discharged at the same time through multiple discharge ports, which can disperse the force of the grain when it flows out, reduce the collision and friction between the grain particles, and at the same time reduce the difficulty of closing the grain storage bin.
