Description

Technical Field

[0001] This utility model belongs to the field of agricultural technology and relates to a corn seed storage device. Background Technology

[0002] As an important global food crop, feed ingredient, and industrial raw material, corn seeds need to be stored for a long time before sowing in agricultural production. During the seed storage process, corn seeds will continuously release heat and moisture due to respiration. If the storage device is poorly ventilated and the internal air cannot circulate effectively, heat and moisture will gradually accumulate. This will not only increase the temperature and humidity of the storage environment, creating extremely favorable conditions for the growth of mold, but also cause the seeds to become damp, further reducing seed vigor and germination rate.

[0003] A search revealed a Chinese patent publication number: CN210364879U, which discloses a corn seed storage device, comprising a cylinder with an open upper end and a cover plate at the upper end. A foot pad is fixedly installed at the bottom of the cylinder, and an electromagnet is fixedly installed at the bottom of the inner wall of the cylinder. An air bladder is glued to the upper end of the electromagnet, and the upper end of the air bladder is glued to a magnet block.

[0004] When using the above technology, the following technical problems were found in the existing technology:

[0005] This technical solution effectively solves the problem of poor ventilation and moisture-proof and mildew-proof performance of some existing storage devices. However, after corn seeds are piled up in the cylinder, the top and middle of the cylinder, which are close to the outside, are more likely to have air circulation and therefore will not mold. However, the seeds located at the bottom and center of the cylinder, where air circulation is poor, are more likely to mold. Therefore, the actual effect is not good. Utility Model Content

[0006] The technical problem this invention aims to solve is that, in some storage devices where air circulation is poor and the corn cannot be turned over, the corn piled in the center and at the bottom of the storage device is prone to mold growth due to its own heat generation and inability to dissipate.

[0007] This utility model discloses a corn seed storage device, comprising an outer shell, with evenly distributed ventilation openings on the outer wall of the outer shell, an inner shell fixedly connected to the bottom of the inner cavity of the outer shell, evenly distributed air inlet openings on the outer wall of the inner shell, a breathable mesh fixedly connected to the inner wall of the inner shell, an installation plate fixedly connected to the top of the inner shell, a flipping mechanism installed between the installation plate and the bottom of the inner cavity of the outer shell, an airflow mechanism provided between the outer shell and the inner shell, the airflow mechanism being fixedly connected to the flipping mechanism, a conical tube fixedly connected to the top of the outer shell, the conical tube communicating with the interior of the outer shell and the inner shell, evenly distributed support legs fixedly connected to the bottom of the outer shell, and a discharge mechanism provided at the bottom of the outer shell.

[0008] Preferably, the flipping mechanism includes a transmission rod, one end of which passes through a mounting plate and is movably connected to the mounting plate, and the other end of which passes through a housing and is movably connected to the housing. One end of the transmission rod is fixedly connected to an air circulation mechanism, and the other end is fixedly connected to a worm gear. A spiral blade is fixedly connected to the side wall of the transmission rod. Rectangular plates are symmetrically fixedly connected to the bottom of the housing. A worm is provided between the two rectangular plates. The worm meshes with the worm gear. Both ends of the worm pass through the rectangular plates and are movably connected to the rectangular plates. A rocker arm is fixedly connected to one end of the worm.

[0009] Preferably, the air circulation mechanism includes a rotating plate, which is arranged in a cross shape.

The fan blades are located between the outer shell and the inner shell. A conical plate is fixedly connected to the top of the rotating plate.

[0010] Preferably, the discharge mechanism includes a discharge opening located at the bottom of the outer shell near one side. A discharge pipe is fixedly connected to the bottom of the outer shell and communicates with the interior of the inner shell. A baffle is provided on one side of the discharge pipe, and the side of the baffle opposite to the worm gear passes through the discharge pipe and is movably connected to the discharge pipe.

[0011] Furthermore, the outer wall of the outer shell is slidably connected with movable rings near the top and bottom, and a number of evenly distributed sealing plates are fixedly connected between two movable rings, the sealing plates matching the vent openings.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1

[0030] like Figures 1-9 As shown, the device includes an outer shell 1, with evenly distributed ventilation openings 2 on the outer wall of the outer shell 1. An inner shell 3 is fixedly connected to the bottom of the inner cavity of the outer shell 1. An evenly distributed air inlet opening 4 is opened on the outer wall of the inner shell 3. A breathable mesh 5 is fixedly connected to the inner wall of the inner shell 3. An installation plate 8 is fixedly connected to the top of the inner shell 3. A flipping mechanism is installed between the installation plate 8 and the bottom of the inner cavity of the outer shell 1. An air flow mechanism is provided between the outer shell 1 and the inner shell 3. The air flow mechanism is fixedly connected to the flipping mechanism. A tapered tube 24 is fixedly connected to the top of the outer shell 1. The tapered tube 24 communicates with the interior of the outer shell 1 and the inner shell 3. Evenly distributed support legs 23 are fixedly connected to the bottom of the outer shell 1. A discharge mechanism is provided at the bottom of the outer shell 1.

[0031] In this technical solution, both the outer shell 1 and the inner shell 3 are made of stainless steel, which provides better support and is less prone to deformation. In addition, the metal material conducts heat quickly. The mesh on the breathable mesh 5 has small holes, which prevents corn seeds from passing through the mesh, thus achieving the functions of ventilation and interception.

[0032] like Figures 2-5 As shown, the flipping mechanism includes a transmission rod 6. One end of the transmission rod 6 passes through the mounting plate 8 and is movably connected to the mounting plate 8, and the other end passes through the outer shell 1 and is movably connected to the outer shell 1. One end of the transmission rod 6 is fixedly connected to the air circulation mechanism, and the other end is fixedly connected to a worm gear 11. A spiral blade 7 is fixedly connected to the side wall of the transmission rod 6. Rectangular plates 15 are symmetrically fixedly connected to the bottom of the outer shell 1. A worm gear 14 is arranged between the two rectangular plates 15. The worm gear 14 meshes with the worm gear 11. Both ends of the worm gear 14 pass through the rectangular plates 15 and are movably connected to the rectangular plates 15. A rocker arm 16 is fixedly connected to one end of the worm gear 14.

[0033] The turning mechanism can quickly turn the corn seeds located in the center of the inner shell 3 outwards, and at the same time, it will mix with the corn seeds near the outer edge. This makes heat dissipation more even and can effectively prevent the corn seeds in the middle from becoming moldy because the heat cannot be dissipated in time.

[0034] Example 2

[0035] like Figures 3-6 As shown, the air circulation mechanism includes a rotating plate 9, which is arranged in a cross shape. The bottom of the rotating plate 9 is fixedly connected to the top of the transmission rod 6. The bottom of the rotating plate 9 is fixedly connected to evenly distributed fan blades 12, which are located between the outer shell 1 and the inner shell 3. The top of the rotating plate 9 is fixedly connected to a conical plate 10.

[0036] The air circulation mechanism can accelerate the airflow between the outer shell 1 and the inner shell 3, thereby accelerating the airflow inside the inner shell 3. In addition, the tilt direction of the fan blade 12 can be adjusted during the manufacturing process, making it more flexible to use.

[0037] like Figure 2 and Figure 9 As shown, the discharge mechanism includes a discharge opening 17, which is located at the bottom of the outer shell 1 near one side. A discharge pipe 18 is fixedly connected to the bottom of the outer shell 1. The discharge pipe 18 is connected to the interior of the inner shell 3. A baffle 20 is provided on one side of the discharge pipe 18. The side of the baffle 20 opposite to the worm gear 11 passes through the discharge pipe 18 and is movably connected to the discharge pipe 18.

[0038] In this technical solution, both the discharge pipe 18 and the baffle 20 are made of stainless steel, which ensures that the baffle 20 will not be bent and is more stable in use. The baffle 20 is L-shaped and has a handle hole on one side, which makes it more convenient to pull out the baffle 20.

[0039] Among them, movable rings 21 are slidably connected to the outer wall of the outer shell 1 near the top and bottom, and several evenly distributed sealing plates 22 are fixedly connected between the two movable rings 21. The sealing plates 22 are matched with the ventilation openings 2. Multiple sealing plates 22 can be rotated by the movable rings 21. In humid weather or when ventilation is not required, the movable rings 21 can be rotated so that multiple sealing plates 22 cover the ventilation openings 2 on the outer shell 1, which can largely prevent humid air from entering the outer shell 1 and effectively protect the corn seeds.

[0040] In addition, a scraper 13 is fixedly connected to the side wall of the transmission rod 6 near the bottom. The scraper 13 can move the corn seeds at the bottom of the inner shell 3 because the spiral blade 7 cannot lift some of the bottom corn seeds upwards, so it is necessary to move them.

[0041] The tapered tube 24 is equipped with a sealing cover 25. A movable connecting plate 26 is fixedly connected to one side of the sealing cover 25. Fixed connecting plates 19 are movably connected to the front and rear side walls of the movable connecting plate 26 respectively. One side of the fixed connecting plate 19 is fixedly connected to the outer wall of the tapered tube 24. The sealing cover 25 can close the outer shell 1 when needed, so that humid air will not enter the outer shell 1. It can also be opened when necessary to accelerate air circulation, because the heat will dissipate upward. After opening, more heat will dissipate from the top of the outer shell 1.

[0042] Working Principle: When using this technical solution, first move the outer shell 1 to the desired location, open the sealing cap 25, and then pour the corn seeds to be stored into the conical tube 24 and into the inner shell 3. During storage, both the ventilation opening 2 and the inner shell 3 provide ventilation and heat dissipation for the seeds. However, the airflow to the corn seeds near the center of the inner shell 3 is poor. Therefore, it is necessary to swap the positions of the corn seeds near the center with the seeds on the periphery. First, rotate the worm gear 14 using the rocker arm 16. The worm gear 14 drives the worm wheel 11 and the transmission rod 6 to reverse direction. Then, the transmission rod 6 drives the spiral blades 7 to reverse direction. The reverse rotation of the spiral blades 7 lifts the corn seeds in the center upwards. Simultaneously, because the central corn seeds are lifted upwards, the seeds near the periphery flow towards the center due to pressure. This process is repeated to lift the central corn seeds... The seeds are evenly mixed with the surrounding corn seeds, which quickly cools down the heated seeds. Furthermore, rotating the transmission rod 6 also reverses the rotation of the rotating plate 9 and the fan blade 12. The rotation of the fan blade 12 accelerates airflow, further accelerating the cooling of the seeds. Continuing to rotate the worm gear 11 through the above operations effectively solves the problem of heat not dissipating from the corn seeds located in the center after heating. When it is necessary to release the corn seeds from the inner shell 3, the baffle 20 can be pulled out, and the corn seeds in the inner shell 3 will flow into the discharge pipe 18 through the discharge opening 17. If blockage occurs, the transmission rod 6 is rotated again through the above operations, causing the scraper 13 to rotate and clean the inlet of the discharge opening 17. This effectively solves the blockage problem.

[0043] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
