Description

Technical Field

[0001] The utility model belongs to the technical field of walkway boards and relates to a walkway board on the surface of a grain pile. Background Art

[0002] Grain reserves mainly include paddy rice, wheat, corn, soybeans, etc., which are mostly granular objects. In order to understand the pest damage, mildew, weather conditions, etc. in the granary at any time, the storage personnel often need to enter the warehouse for observation, sampling, etc. Since it is not easy to walk on granular objects, a walkway board needs to be laid on the surface of the grain pile.

[0003] For the existing walkway board, for example, a kind of grain surface walkway board is disclosed in the Chinese patent literature [Patent No.: 201520860591.X; Application Publication No.: CN205100055U], which includes a board body. A number of uniformly distributed air holes are provided on the board body, and board edges are provided around the lower part of the board body; a number of longitudinally distributed partitions and a number of transverse partitions perpendicular to the longitudinally distributed partitions are provided on the lower surface of the board body; the board edges, longitudinally distributed partitions and transverse partitions divide the space on the lower surface of the board body into a number of uniformly distributed anti-slip spaces; a barrier tube extends downward from the air hole, and the barrier tube is located in the anti-slip space; the inner diameter range of the barrier tube is 0.5 cm to 2 cm; the height of the barrier tube is equal to or greater than 0.5 cm.

[0004] For the grain surface walkway board with such a structure, a number of uniformly distributed air holes are provided on the board body, and the air holes play a role in ventilation to prevent the grain below the walkway board from getting moldy. However, for the grain surface walkway board with such a structure, after the operator walks on the walkway board and applies a certain pressure to the walkway board, there is a problem that the grain overflows from the air holes and enters above the walkway board. Moreover, the surface of the grain surface walkway board with such a structure is flat and smooth, which causes the problem that the operator steps on the grain during walking and there is a risk of falling, and there are certain potential safety hazards. Summary of the Invention

[0005] The purpose of the utility model is to provide a walkway board on the surface of a grain pile for the above problems existing in the prior art, and the technical problem to be solved is how to prevent the operator from falling when walking on the walkway board and improve safety.

[0006] The purpose of the utility model can be realized by the following technical solutions: A walkway board on the surface of a grain pile includes a board body, and a number of air holes are arranged at intervals in the board body. It is characterized in that a ring-shaped convex ring is provided at the circumferential edge at the top of each air hole, the convex ring protrudes from the upper surface of the board body, and the outer side wall of the convex ring is inclined obliquely outward and downward from the middle to the periphery.

[0007] The convex ring protrusions are arranged on the upper surface of the plate body, making the surface of the walkway plate uneven. When the operator walks on the walkway plate, the friction is increased, and the operator will not fall, improving safety. At the same time, even if grains enter above the plate body through the ventilation holes or the side of the walkway plate, due to the arrangement of the convex ring protrusions, the grains are still on the plate body and will not contact the soles of the operator's shoes, so there is no problem of the operator stepping on the grains and falling, improving safety. The outer side wall of the convex ring is inclined obliquely outward and downward from the middle to the periphery, playing a better role in unloading force, so that when the plate body at the ventilation hole bears the weight pressure of the operator, it is not easily damaged. The arrangement of the ventilation holes ensures that the grains under the walkway plate have sufficient ventilation area, the grains are not easily heated, and the grains will not mildew.

[0008] In the above-mentioned walkway plate on the surface of the grain pile, the top of the convex ring has a horizontal contact surface. The contact area between the convex ring and the sole of the operator's shoe is increased, the pressure borne by the convex ring is dispersed, the convex ring is not easily damaged, and at the same time, the operator walks steadily on the walkway plate.

[0009] In the above-mentioned walkway plate on the surface of the grain pile, the outer side wall of the convex ring is a convex arc surface or an inclined plane.

[0010] In the above-mentioned walkway plate on the surface of the grain pile, the lower surface of the plate body has a number of upwardly recessed receiving grooves, the receiving grooves are arranged at the circumferential edge of the ventilation holes, and the receiving grooves are arranged in one-to-one correspondence with the convex rings. The receiving grooves and the convex rings are formed together during processing, with one side being convex and the other side being concave. The design is reasonable and the processing is convenient. Moreover, the receiving grooves can allow the grains to be embedded, making the walkway plate better positioned on the grain surface and improving the stability of the walkway plate.

[0011] In the above-mentioned walkway plate on the surface of the grain pile, the circumferential edge of the ventilation hole extends downward to form a barrier tube, and the receiving groove is sleeved outside the top of the barrier tube. The arrangement of the barrier tube extends the length of the ventilation hole, making it difficult for the grains to enter the upper surface of the plate body through the ventilation hole. At the same time, the barrier tube can be embedded in the grains, making the walkway plate better positioned on the grain surface and improving the stability of the walkway plate.

[0012] In the above-mentioned walkway plate on the surface of the grain pile, the plate body, the convex ring and the barrier tube are integrally formed by injection molding. Integral forming by injection molding is convenient for processing.

[0013] In the above-mentioned walkway board on the surface of a grain pile, the upper surface of the board body further has a number of strip-shaped grooves recessed downward, and the strip-shaped grooves are located between two adjacent columns of the ventilation holes. The arrangement of the strip-shaped grooves makes the board body concave and convex, which can enhance the strength of the board body; the strip-shaped grooves can allow the grains that accidentally run onto the board body to be embedded, so that the operator's feet will not step on the grains, improving safety; at the same time, the strip-shaped grooves are recessed, so that the lower surface of the board body has a strip-shaped protrusion, making the walkway board better positioned on the grain surface and improving the stability of the walkway board.

[0014] In the above-mentioned walkway board on the surface of a grain pile, the cross-section of the strip-shaped groove is semicircular or U-shaped.

[0015] In the above-mentioned walkway board on the surface of a grain pile, the widths of all the strip-shaped grooves are the same or the width of the strip-shaped groove at one end of the board body is greater than the width of the strip-shaped groove at the other end of the board body.

[0016] In the above-mentioned walkway board on the surface of a grain pile, the strip-shaped grooves are arranged along the width direction of the board body, and all the strip-shaped grooves are parallel to each other.

[0017] Compared with the prior art, the walkway board on the surface of a grain pile provided by the present utility model has the following advantages:

[0018] 1. The upper surface of the board body of this walkway board is provided with a convex ring in a raised manner. The convex ring increases the friction force, and at the same time, enables the operator to walk on the walkway board without contacting the grains, preventing the operator from falling and improving safety.

[0019] 2. The board body of this walkway board is provided with strip-shaped grooves, which enhance the strength of the board body. At the same time, it enables the operator to walk on the walkway board without contacting the grains, preventing the operator from falling and improving safety. Description of the Drawings
