Description

Technical Field

[0001] The present invention relates to the field of walkway boards on the grain surface, and more specifically, to a walkway board with anti-corrosion, anti-moth, anti-mildew, and anti-toxic functions for the grain surface. Background Art

[0002] The walkway board on the grain surface is a device applied to grain storage facilities, mainly used to provide a walking and operating platform inside the grain storage warehouse. In modern large granaries, in order to facilitate the daily inspection, maintenance, and operation of the staff, walkway boards are usually laid on the surface of the grain pile. These walkway boards not only need to provide a stable and safe walking platform, but also need to have good ventilation performance to ensure the dryness and cleanliness of the grain storage environment, prevent the growth of mold, the reproduction of pests, and the accumulation of harmful gases.

[0003] The most common and commonly used types of walkway boards are the groove ventilation type, the flat-bottom simple type, and the flexible splicing type. For the groove ventilation type of walkway board, this design often has a groove structure at its bottom, and these grooves are designed to promote air circulation, reduce the humidity inside the grain pile, and maintain suitable storage conditions.

[0004] However, in actual applications, especially in a high-density grain storage environment, when people walk on the walkway board, due to the action of the human body weight, the walkway board will move downward and be in close contact with the grain surface. In this case, the grain particles are easy to enter the inside of the groove, resulting in the difficulty for the walkway board to return to its original position, and it is unable to effectively maintain an appropriate gap with the grain surface. As a result, the space originally used for air circulation is blocked, leading to a significant reduction in ventilation efficiency. This will make it difficult for the moisture inside the grain pile to be discharged, increasing the risk of mold growth, and further affecting the quality and safety of the grain. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a walkway board with anti-corrosion, anti-moth, anti-mildew, and anti-toxic functions for the grain surface, which can facilitate the reset of the stepped-on walkway board, so that there is a good ventilation effect between the grain and the walkway board, and it can avoid the situation that the traditional walkway board cannot return to its original position after being stepped on, resulting in a significant reduction in ventilation efficiency, and can effectively improve the quality and safety of the grain.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A walkway board with anti-corrosion, anti-moth, anti-mildew, and anti-toxic functions for the grain surface, including a walkway frame, a bottom plate is slidably installed in the inner cavity of the walkway frame, and coatings are provided on the surfaces of the walkway frame and the bottom plate;

[0008] It further includes:

[0009] Reset component, the reset component includes a reset spring and an elastic airbag uniformly and fixedly installed between the bottom plate and the inner cavity of the aisle frame. Through holes are uniformly formed in the bottom plate. Above each group of through holes, there is a fixing rod adapted to it. Each fixing rod is provided with an air blowing hole inside. The air outlet ends of each group of elastic airbags are arranged at the side wall and the bottom. The air outlet ends on the side walls of each group of elastic airbags are fixedly installed with connecting pipes. The other end of each group of connecting pipes penetrates through the adjacent fixing rod and is communicated with the air blowing hole. Ventilation openings 1 are uniformly formed at the top of the aisle frame, and ventilation openings 2 are uniformly formed on the side walls of the aisle frame. A anti-blocking component is arranged below the fixing rod.

[0010] Further, the anti-blocking component includes filter blocks uniformly arranged below the fixing rod. The filter blocks are adapted to the inner cavity of the air blowing hole. Insertion plates are uniformly and fixedly installed at the bottom of the bottom plate. The bottom of each group of filter blocks is fixedly installed with an L-shaped rod. The other end of each group of L-shaped rods is fixedly installed with one side of the adjacent insertion plate. A conical frame is arranged on the outer side of the bottom of each group of fixing rods. Each group of conical frames is fixedly installed with the top of the bottom plate.

[0011] Further, an air storage cavity is formed in each group of insertion plates. Air outlet holes communicated with the adjacent air storage cavity are uniformly formed on the side walls of each group of insertion plates. Exhaust channels are uniformly formed in the bottom plate. The air inlet ends of each group of elastic airbags are arranged on their side walls and are communicated with the inner cavity of the aisle frame. The top ends of each group of exhaust channels are fixedly installed with the bottom air outlet ends of the adjacent elastic airbags. The bottom ends of each group of exhaust channels are communicated with the inner cavity of the adjacent air storage cavity.

[0012] Further, a cross plate is fixedly installed on one side wall of each group of conical frames. A T-shaped block is slidably installed on each cross plate. Grooves adapted to the T-shaped blocks are formed on the top of the bottom plate. Each group of T-shaped blocks is in contact with the bottom wall of the inner cavity of the adjacent groove. A telescopic spring is fixedly installed between each group of T-shaped blocks and the adjacent cross plate.

[0013] Further, an installation block is arranged directly above each group of cross plates. Each group of installation blocks is fixedly installed with the adjacent fixing rod. Magnet blocks are fixedly installed between each group of installation blocks and the top ends of the adjacent T-shaped blocks.

[0014] Further, cavities are formed in the two side walls of the aisle frame. U-shaped rods are in contact with the bottom walls of the inner cavities of the two groups of cavities. The other ends of the two groups of U-shaped rods are fixedly installed with the top of the bottom plate.

[0015] Further, chutes adapted to the U-shaped rods are formed on the inner walls on both sides of the aisle frame, and each set of the return springs is in a compressed state in the initial state.

[0016] Further, clamping members are uniformly and fixedly installed on one side wall of the aisle frame, and clamping openings adapted to the clamping members are formed on the other side wall of the aisle frame.

[0017] Further, sealing rings are fixedly installed in the inner cavities of each set of through openings, and the bottom ends of each set of plug boards are pointed.

[0018] Further, each set of telescopic springs is in a compressed state in the initial state, and the magnetic attraction force of the two magnet blocks is greater than the elastic force of the telescopic springs.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) When the user moves out of the top of the aisle frame, the return spring will push the aisle frame upward to the initial position. At the same time, under the action of the elastic airbag, the air inlet end of the elastic airbag will suck the outside air into the inner cavity of the aisle frame through the first ventilation opening and the second ventilation opening, so as to realize rapid ventilation of the inner cavity of the aisle frame. At the same time, when the elastic airbag returns to the initial state, it will also apply an upward thrust to the aisle frame, which can help the aisle frame return to its original position, play a certain role in assisting reset, reduce the dependence on the return spring, thereby effectively improving the reset effect, and maintaining a good ventilation space for the grain surface, avoiding the situation that the traditional aisle board is difficult to reset, resulting in the blockage of the space originally used for air circulation and a significant reduction in ventilation efficiency, and effectively improving the quality and safety of the grain.

[0021] (2) When the user steps on the aisle frame and moves it downward, the aisle frame will squeeze the elastic airbag when moving downward. When the aisle frame moves downward, it will also drive the fixed rod to move downward synchronously. The fixed rod will enter the through opening and squeeze the surplus grain in the through opening downward. The elastic airbag will blow air into the connecting pipe when being squeezed. The gas in the connecting pipe will be discharged into the air blowing holes. The gas will blow downward along the L-shaped rod after passing through the filter block in the air blowing holes. Finally, the gas will be discharged into the grain, playing a role in blowing air into the grain, which can enhance the air flow inside the grain pile, help reduce the local humidity, reduce the possibility of mold growth, and also help regulate the temperature of the grain pile, and improve the environment of the grain surface to a certain extent.

[0022] (3) When the gas in the elastic airbag is squeezed, it will be discharged into the air blowing hole through the connecting pipe. At the same time, the gas will also be discharged into the storage cavity through the exhaust channel. The gas will finally be discharged through the air outlet hole into the grain, which can realize the supply of gas to the inside of the grain again. The gas flow can slightly disturb the surface of the grain pile, prevent the grain particles from caking due to long-term static state, maintain the good fluidity of the grain, and at the same time help to break the living environment of pests and reduce their breeding opportunities in the grain pile. If some volatile organic compounds or other harmful gases are generated in the grain pile, it can also help to discharge these gases in time and improve the air quality of the storage environment.

Detailed Embodiment

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 7 , a grain surface anti-corrosion, anti-moth, anti-mildew and anti-toxic walkway board, which includes a walkway frame 1. A bottom plate 3 is slidably installed in the inner cavity of the walkway frame 1. Coating layers 2 are provided on the surfaces of both the walkway frame 1 and the bottom plate 3;

[0034] It further includes:

[0035] A reset assembly, which includes a reset spring 4 and an elastic airbag 6 uniformly and fixedly installed between the bottom plate 3 and the inner cavity of the walkway frame 1. Through holes 5 are uniformly opened on the bottom plate 3. Fixing rods 7 adapted to the through holes 5 are provided above each group of through holes 5. Air blowing holes 27 are opened in each group of fixing rods 7. The air outlet ends of each group of elastic airbags 6 are arranged at the side walls and the bottom. The air outlet ends on the side walls of the elastic airbags 6 are fixedly installed with connecting pipes 8. The other ends of each group of connecting pipes 8 penetrate through the adjacent fixing rods 7 and are communicated with the air blowing holes 27. Ventilation openings one 21 are uniformly opened at the top of the walkway frame 1. Ventilation openings two 22 are uniformly opened on the side walls of the walkway frame 1. A blockage prevention assembly is provided below the fixing rods 7.

[0036] The blockage prevention assembly includes filter blocks 11 uniformly arranged below the fixing rods 7. The filter blocks 11 are adapted to the inner cavities of the air blowing holes 27. Insertion plates 9 are uniformly and fixedly installed at the bottom of the bottom plate 3. L-shaped rods 10 are fixedly installed at the bottoms of each group of filter blocks 11. The other ends of each group of L-shaped rods 10 are fixedly installed with one side of the adjacent insertion plates 9. Conical frames 12 are arranged on the outer sides of the bottoms of each group of fixing rods 7. Each group of conical frames 12 is fixedly installed on the top of the bottom plate 3.

[0037] When in use, first place this device on the surface of the grain. The bottoms of the groups of inserting plates 9 will contact the surface of the grain. At this time, there will be a spacing between the bottom plate 3 and the surface of the grain. Then press the walkway frame 1 downward. Under the elastic force of the reset spring 4 and the elastic airbag 6, it will push the bottom plate 3 to drive the groups of inserting plates 9 to move downward on the surface of the grain, and the groups of inserting plates 9 can be inserted into the grain. After the groups of inserting plates 9 are completely inserted into the grain, the bottom of the bottom plate 3 will contact the surface of the grain. Through the setting of the groups of inserting plates 9, the contact area with the grain can be increased, and the bottom plate 3 and the walkway frame 1 can be fixed more firmly on the grain surface, reducing the sliding or displacement phenomena caused by personnel walking or external disturbances, and effectively improving its use stability. Since both the walkway frame 1 and the bottom plate 3 are made of stainless steel, they have extremely high corrosion resistance and strength, are not easily eroded by pests or microorganisms, and have good moisture resistance performance, which helps to prevent mold growth. Moreover, they are food-grade safety materials and will not release harmful substances. Since the coating 2 is made of an epoxy resin coating containing antibacterial components, it has excellent adhesion, wear resistance and chemical resistance, provides a strong barrier protection, avoids corrosion and pests, inhibits mold growth, and is usually non-toxic, and can achieve the functions of anti-corrosion, anti-moth, anti-mold and anti-toxic;

[0038] The elastic airbag 6 does not contact the front and rear side walls of the inner cavity of the walkway frame 1, and there is a gap. In the initial state, there is a distance between the bottom plate 3 and the inner cavity of the walkway frame 1. The cooperation of the first ventilation opening 21 and the second ventilation opening 22 is used for air circulation, and ventilation of the inner cavity of the walkway frame 1 can be achieved. Then, through each group of through openings 5, the grains at the bottom of the bottom plate 3 are connected, which can ensure good ventilation performance. When the user steps on the top of the walkway frame 1, since the contact area between the bottom of the bottom plate 3 and the grain surface is large, and the contact area between the bottom of the walkway frame 1 and the grain surface is small, at this time, under the action of the user's own gravity, the walkway frame 1 will be pressed to move downward outside the bottom plate 3 and move into the grains. When the walkway frame 1 moves downward, it will squeeze the return spring 4 and the elastic airbag 6. When the walkway frame 1 moves downward, it will also drive the fixing rod 7 to move downward synchronously. During the downward movement of the fixing rod 7, the air blowing hole 27 will first be inserted outside the filter block 11. When the fixing rod 7 continues to move downward, it will enter the through opening 5. When the bottom plate 3 is installed on the surface of the grains, due to the setting of the through opening 5, part of the grains will enter the through opening 5. When the fixing rod 7 moves downward in the through opening 5, the remaining grains in the through opening 5 will be squeezed downward. At the same time, when the walkway frame 1 moves downward and squeezes the elastic airbag 6, the gas in the elastic airbag 6 will be squeezed and discharged into the connecting pipe 8. The gas in the connecting pipe 8 will be discharged into the air blowing hole 27. The gas in the air blowing hole 27 will pass through the filter block 11 and blow downward along the L-shaped rod 10. Finally, the gas will be discharged into the grains, playing a role in blowing air into the grains, which can enhance the air flow inside the grain pile, help reduce the local humidity, reduce the possibility of mold growth, and at the same time help regulate the temperature of the grain pile, and to a certain extent, improve the environment of the grain surface;

[0039] When the user moves away from the top of the walkway frame 1, there is no longer pressure exerted on the top of the walkway frame 1. Under the action of the return spring 4, the return spring 4 returns to its initial state and pushes the walkway frame 1 to move upward on the outer wall of the bottom plate 3 to the initial position. At the same time, under the action of the elastic airbag 6, the intake end of the elastic airbag 6 absorbs external gas through the first vent 21 and the second vent 22 into the inner cavity of the walkway frame 1, which can achieve rapid ventilation of the inner cavity of the walkway frame 1. At the same time, when the elastic airbag 6 returns to its initial state, it will also exert an upward thrust on the walkway frame 1, which can help the walkway frame 1 return to its original position, playing a certain role in assisting the reset, reducing the dependence on the return spring 4, thereby effectively improving the reset effect and maintaining a good ventilation space for the grain surface, avoiding the situation where the traditional walkway board is difficult to reset, resulting in the blockage of the space originally used for air circulation and a significant reduction in ventilation efficiency, and effectively improving the quality and safety of the grain; when the walkway frame 1 drives the fixed rod 7 to move upward, the fixed rod 7 slides upward on the outer wall of the filter block 11 through the air blowing hole 27. Through the filter block 11, the remaining grains in the air blowing hole 27 can be scraped off, playing a role in cleaning, preventing the air blowing hole 27 from being blocked. At the same time, through the setting of the filter block 11 itself, it is convenient for the gas in the air blowing hole 27 to be discharged downward through the filter block 11.

[0040] As Figure 3 and Figure 5 shown, an air storage cavity 26 is provided in each group of insertion plates 9, and air outlet holes 14 communicating with the adjacent air storage cavities 26 are uniformly provided on the side walls of each group of insertion plates 9. An exhaust passage 13 is uniformly provided in the bottom plate 3. The intake ends of each group of elastic airbags 6 are arranged on their side walls and are communicated with the inner cavity of the walkway frame 1. The top ends of each group of exhaust passages 13 are fixedly installed with the bottom air outlet ends of the adjacent elastic airbags 6, and the bottom ends of each group of exhaust passages 13 are communicated with the inner cavities of the adjacent air storage cavities 26.

[0041] The aperture of each air outlet hole 14 is smaller than the size of the grain to prevent the grain from entering the insertion plate 9 through the air outlet hole 14. When the user steps on the walkway frame 1 and moves it downward, the elastic airbag 6 will be squeezed. While the gas in the elastic airbag 6 is squeezed and discharged into the air blowing hole 27 through the connecting pipe 8, the gas will also be discharged into the air storage cavity 26 through the exhaust passage 13. The gas will finally be discharged through the air outlet hole 14 in the air storage cavity 26 and into the grain, which can realize secondary air supply to the inside of the grain. The gas flow can slightly disturb the surface of the grain pile, prevent the grain particles from caking due to long-term static state, maintain the good fluidity of the grain, and at the same time help to break the living environment of pests and reduce their reproduction opportunities in the grain pile. If some volatile organic compounds or other harmful gases are generated in the grain pile, it can also help to discharge these gases in time and improve the air quality of the storage environment.

[0042] As Figure 5As shown, a cross plate 15 is fixedly installed on one side wall of each group of conical frames 12. A T-shaped block 16 is slidably installed on each cross plate 15. Grooves 17 adapted to the T-shaped blocks 16 are formed in the top of the bottom plate 3. Each T-shaped block 16 is in contact with the inner cavity bottom wall of the adjacent groove 17. A telescopic spring 18 is fixedly installed between each T-shaped block 16 and the adjacent cross plate 15.

[0043] An installation block 19 is arranged directly above each cross plate 15. Each installation block 19 is fixedly installed with the adjacent fixed rod 7. Magnet blocks 20 are fixedly installed between the top of each installation block 19 and the adjacent T-shaped block 16.

[0044] When the user steps on the walkway frame 1 and moves it downward, the walkway frame 1 drives the installation block 19 to move downward synchronously through the fixed rod 7. When the bottom of the installation block 19 touches the top of the conical frame 12, at this time, the walkway frame 1 cannot continue to move downward, playing a limiting role, which can protect the self-elastic force of the return spring 4 and the elastic airbag 6, prevent the situation that they are compressed to the maximum extent and cause elastic damage, and can effectively improve the elastic effect of the return spring 4 and the elastic airbag 6. When the installation block 19 contacts the conical frame 12, the two magnet blocks 20 in the vertical direction will contact and magnetically attract each other. When the user moves away from the top of the walkway frame 1, under the action of the return spring 4 and the elastic airbag 6, the walkway frame 1 is pushed upward to the initial position, which can realize that the fixed rod 7 drives the installation block 19 to move upward. The installation block 19 will pull the T-shaped block 16 upward and compress the telescopic spring 18 through the two magnet blocks 20 magnetically attracted to each other. When the telescopic spring 18 is compressed to the maximum extent, when the installation block 19 continues to move upward, the two magnet blocks 20 will separate. At this time, under the action of the telescopic spring 18, the telescopic spring 18 returns to the initial state and pushes the T-shaped block 16 downward to the initial position, which can realize that the telescopic spring 18 pushes the T-shaped block 16 to impact the inner cavity of the groove 17. Through the arrangement of multiple groups of T-shaped blocks 16, vibration can be generated on the bottom plate 3. Because the contact area between the bottom plate 3 and the grain surface is large, the vibration can slightly disturb the surface of the grain pile, help to loosen the grain particles, prevent caking phenomenon, and can also help to break the static air layer inside the grain pile, promote the circulation of air in the grain pile, help to discharge moisture, and reduce the risk of mold growth.

[0045] As Figure 5 shown, cavities 23 are formed in the inner walls on both sides of the walkway frame 1. The inner cavity bottom walls of the two cavities 23 are in contact with U-shaped rods 24. The other ends of the two U-shaped rods 24 are fixedly installed on the top of the bottom plate 3.

[0046] Chutes 25 adapted to the U-shaped rods 24 are formed in the inner walls on both sides of the walkway frame 1. In the initial state, each return spring 4 is in a compressed state.

[0047] When the user steps on the aisle frame 1 and moves it downward, the downward movement of the aisle frame 1 on the outer wall of the bottom plate 3 will squeeze the return spring 4 and the elastic airbag 6. At the same time, the inner cavity bottom wall of the cavity 23 will move away from the bottom end of the U-shaped rod 24. When the user removes their foot from the top of the aisle frame 1, under the action of the return spring 4 and the elastic airbag 6, the aisle frame 1 is pushed upward to its initial position. It can be realized that when the aisle frame 1 moves to the initial state, the inner cavity bottom wall of the cavity 23 will impact on the bottom end of the U-shaped rod 24, which can generate vibration for the aisle frame 1, further realizing the vibration effect, and realizing the effect of disturbing the grain pile and promoting air flow again. At the same time, in a grain environment with relatively high viscosity, the grains adhering to the outer wall of the aisle frame 1 can be shaken off to avoid residue.

[0048] As Figure 1 and Figure 5 shown, clamping members 29 are uniformly and fixedly installed on one side wall of the aisle frame 1, and bayonet openings 30 adapted to the clamping members 29 are formed on the other side wall of the aisle frame 1.

[0049] Sealing rings 28 are fixedly installed in the inner cavities of each group of through openings 5, and the bottom ends of each group of insertion plates 9 are provided with pointed shapes.

[0050] In the initial state, each group of telescopic springs 18 is in a compressed state, and the magnetic attraction force of the two magnet blocks 20 is greater than the elastic force of the telescopic springs 18.

[0051] When multiple groups of aisle frames 1 need to be spliced and installed, only need to correspondingly insert the clamping member 29 on one group of aisle frames 1 into the bayonet opening 30 on another group of aisle frames 1, and then push the clamping member 29 forward to be stuck on the side wall inside the bayonet opening 30 to achieve rapid splicing and installation. Due to the pointed settings of the bottom ends of the insertion plates 9, it is convenient to insert the insertion plates 9 into the grains to install the bottom plate 3. Through the setting of the sealing rings 28, the sealing performance can be improved when the fixing rods 7 enter the through openings 5, preventing gas from flowing from the through openings 5 into the aisle frames 1.

[0052] Working principle: First, insert each group of inserting plates 9 into the grain. Press the aisle frame 1 to move downward so that the bottom plate 3 contacts the surface of the grain, and the installation can be achieved. Ventilation between the bottom plate 3 and the inner cavity of the aisle frame 1 is realized through the setting of the first ventilation opening 21 and the second ventilation opening 22. Then, ventilation effect on the grain is achieved through each group of through openings 5. When the user steps on the top of the aisle frame 1, the aisle frame 1 will be pressed to move downward and squeeze the return spring 4 and the elastic airbag 6. The fixed rod 7 will move downward with the aisle frame 1 to squeeze the remaining grain in the through opening 5 to the lower side of the through opening 5. When the elastic airbag 6 is squeezed, its air outlet ends will blow air into the connecting pipe 8 and the exhaust passage 13 respectively. The gas in the connecting pipe 8 will be blown downward into the grain through the air blowing holes 27. The gas in the exhaust passage 13 will enter the air storage cavity 26 and be discharged into the interior of the grain through the air outlet holes 14, realizing the function of blowing air into the grain. When the aisle frame 1 moves downward, the inner cavity bottom wall of the cavity 23 will move away from the bottom of the U-shaped rod 24. When the fixed rod 7 moves downward and the mounting block 19 contacts the top of the conical frame 12, the two magnet blocks 20 will be magnetically attracted to each other. When the user moves away from the top of the aisle frame 1, under the action of the elastic airbag 6 and the return spring 4, the aisle frame 1 will be pushed upward to the initial position, realizing the effect of automatic reset. The inner cavity bottom wall of the cavity 23 can impact on the bottom of the U-shaped rod 24 to generate vibration. At the same time, when the aisle frame 1 moves upward, the two magnet blocks 20 being magnetically attracted to each other will pull the T-shaped block 16 upward to squeeze the telescopic spring 18. When the two magnet blocks 20 are separated, the telescopic spring 18 will push the T-shaped block 16 downward to impact the inner cavity of the groove 17 to generate vibration on the bottom plate 3, which can disturb the grain pile and promote air flow. When the aisle frame 1 drives the fixed rod 7 to move upward and reset, the filter block 11 can be used to clear the blockage in the air blowing holes 27. Through the cooperation of the clamping part 29 and the clamping opening 30, multiple groups of aisle frames 1 can be spliced.

[0053] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitution or change, and should be covered by the protection scope of the present invention.
