Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grain equipment, in particular to a grain storage box. Background Art
[0002] Grain storage boxes are equipment used to store grain for a long time. Grains such as rice, corn, and wheat, as strategic materials, require grain stations to store a certain amount to prevent food shortages and supply and demand problems caused by natural disasters. The primary condition for storing grains is a dry environment to prevent the grains from sprouting or mildew.
[0003] Most of the existing grain storage equipment in grain stations is ground equipment, which is a large box structure. The box is sealed to prevent the entry of water vapor, etc., and the ground equipment will take up a large ground space, which is a great waste of space for large storage of grain. The silos for storing grain are now basically made of stainless steel or aluminum alloy to prevent water vapor from entering the interior of the silo, so it is completely possible to arrange the silo in an underground excavation style, and apply anti-rust liquid or coating on the surface of the silo to effectively prevent the soil from corroding the side walls of the silo. Although the buried silo can greatly save ground space, it is a problem to take out the grain, especially the old grain, which needs to be used first to ensure the quality, and the new grain can replace the old grain to ensure the freshness and taste of the grain.
[0004] Therefore, the utility model prepares an underground grain storage box, which can be installed in an underground excavation style and is equipped with a spiral grain taking device, so that the grain at the bottom can be taken preferentially, thereby solving the grain taking problem. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] A grain storage box, comprising a cylindrical silo, the silo is installed underground, the top is level with the ground, the bottom of the silo is a conical structure, a discharge pipe is installed at the axis of the silo, the upper end of the discharge pipe is higher than the top of the silo and has an extension section, and the lower end of the discharge pipe extends to the bottom of the silo and retains a certain distance;
[0008] A screw feeder is installed inside the discharge pipe, and the screw feeder is driven by a top motor to extract the grains in the bin.
[0009] Furthermore, the screw feeder includes a spiral blade and a central rotating shaft, the upper and lower parts of the spiral feeder are extended beyond the outlet of the discharge pipe, the output end of the motor acts on the rotating shaft and drives the spiral feeder to rotate. The outer side of the spiral blade has a groove body, and the groove body is equipped with sealing cotton for contacting the inner wall of the discharge pipe.
[0010] Furthermore, a feeding port is provided on the upper side of the bin body and is equipped with a feeding funnel.
[0011] Furthermore, a guide groove is installed above the warehouse body, the upper end of the discharge pipe passes through the guide groove and extends to the top of the guide groove, and the guide groove is installed obliquely.
[0012] The utility model has the following beneficial effects: the silo of the utility model is installed underground, and aluminum alloy is used as the material to prevent the corrosion of the silo by soil and moisture, saving ground space; the interior is a closed space to isolate water vapor and prevent moisture from occurring during grain storage; when taking the internal grain, a spiral feeder and a discharge pipe are used together; the discharge pipe is installed vertically, and the spacing between the bottom pipe opening and the bottom of the silo is used for the grain to gather at this position, and then the spiral feeder is rotated and drawn out, so that the discharge position of the silo is located at the bottom; the bottom is generally old grain, which can be taken first, thereby ensuring the seasonal renewal of the grain in the silo and maintaining its freshness.

[0015] Figure 2 : Schematic diagram of the guide groove position structure of the utility model.
[0016] In the accompanying drawings, the components represented by the various reference numerals are listed as follows: bin body 1 , discharge pipe 2 , screw feeder 3 , motor 21 , spiral blade 31 , rotating shaft 32 , sealing cotton 33 , feeding funnel 11 , guide groove 22 . DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] like Figure 1As shown: A grain storage box includes a cylindrical silo 1, which is in a sealed state and has a shell structure. It is made of aluminum alloy, and the outer wall is coated with anti-corrosion liquid. The silo 1 is installed underground, which greatly saves ground space. The top is level with the ground, and the bottom of the silo 1 is a conical structure. A discharge pipe 2 is installed at the axis position of the silo 1. The upper end of the discharge pipe 2 is higher than the top of the silo 1 and has an extension section. The lower end of the discharge pipe 2 extends to the bottom of the silo 1 and retains a certain distance; the distance is 50-100cm.
[0019] A screw feeder 3 is installed inside the discharge pipe 2 , and the screw feeder 3 is driven by a top motor 21 to extract the grains in the bin body 1 .
[0020] The silo body of the utility model is installed underground, and aluminum alloy is used as the material to prevent the corrosion of the silo body by soil and moisture, thus saving ground space. The interior is a closed space, which isolates water vapor and prevents the grains from getting damp during storage. When taking the internal grains, a spiral feeder and a discharge pipe are used together. The discharge pipe is installed vertically, and the distance between the bottom pipe opening and the bottom of the silo body is used for the grains to gather at this position, and then the spiral feeder is rotated and drawn out, so that the discharge position of the silo body is located at the bottom. The bottom is generally old grain, which can be taken first, thereby ensuring the seasonal renewal of the grains in the silo body and maintaining freshness.
[0021] like Figure 2 As shown: the screw feeder 3 includes a spiral blade 31 and a central shaft 32. The upper and lower parts of the screw feeder 3 are extended beyond the pipe mouth of the discharge pipe 2. The output end of the motor 21 acts on the shaft 32 and drives the screw feeder 3 to rotate.
[0022] The outer side of the spiral blade 31 has a groove body, in which a sealing cotton 33 is installed for contacting the inner wall of the discharge pipe 2. It is used to improve the sealing performance between the spiral blade and the inner wall of the discharge pipe, prevent the side leakage, and prevent the side grains from being squeezed by the spiral blade.
[0023] like Figure 1 As shown: a feeding port is provided on the upper side of the silo 1, and a feeding funnel 11 is provided. The feeding funnel has an inclined portion, which is used to feed the silo. When the truck delivers the grain, it can directly tip the bucket to dump the grain, avoiding the conveying method of the conveyor belt. A guide groove 22 is installed above the silo 1, and the upper end of the discharge pipe 2 passes through the guide groove 22 and extends to the upper side of the guide groove 22. The guide groove 22 is installed at an angle. The guide groove is composed of a bottom plate and a side wall guide wall, which is used to gather the grains transported up and guide them to a designated position.
[0024] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
