Description

Technical Field

[0001] The utility model belongs to the technical field of grain surface walkway boards and relates to grain surface walkway boards. 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, meteorological conditions, etc. in the granary at any time, the storage personnel often need to enter the granary to observe, take samples, etc. Since it is not easy to walk on granular objects, it is necessary to lay walkway boards on the grain surface.

[0003] For the existing walkway boards, for example, a kind of grain surface walkway board is disclosed in the Chinese patent literature [Patent No.: 201520860591.X; Publication No.: CN205100055U], which includes a board body. A number of uniformly distributed ventilation holes are provided on the board body, and board edges are provided around the lower part of the board body; a number of longitudinally arranged partitions and a number of transversely arranged partitions perpendicular to the longitudinally arranged partitions are uniformly distributed on the lower surface of the board body; the board edges, the longitudinally arranged partitions and the transversely arranged 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 ventilation 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 ventilation holes are provided on the board body, and the ventilation holes play a role in ventilation to prevent the grain below the walkway board from getting moldy. However, for the ventilation holes with such a structure, the aperture of the ventilation holes is relatively large, and the ventilation holes are arranged in the vertical direction. After the operator walks through the walkway board, pressure is applied to the walkway board, and there is a problem that the grain overflows from the ventilation holes and enters above the walkway board. There is a 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 grain surface walkway board aiming at the above problems existing in the prior art, and the technical problem to be solved is how to make the grain surface walkway board have good ventilation effect while preventing the grain from overflowing.

[0006] The purpose of the utility model can be realized by the following technical solutions: A grain surface walkway board, including a board body, characterized in that a number of columns of ventilation structures are arranged at intervals in the board body, and each column of the ventilation structures has a number of convex parts protruding upward and concave parts recessed downward, the convex parts and the concave parts are arranged adjacent to each other at intervals, and the side edges of the convex parts are staggered with the side edges of the concave parts to form ventilation holes.

[0007] This grain surface walkway board has ventilation holes between each protruding part and each recessed part. The large number of ventilation holes makes the ventilation effect of the grain surface walkway board good. Moreover, the side edges of the protruding part and the recessed part are staggeredly arranged to form ventilation holes. The ventilation holes are located on the side, and it is not easy for grains to overflow through the ventilation holes. Even if they do overflow, the overflowed grains are located in the recessed part. Since the protruding part protrudes upward and the recessed part recesses downward, that is, the protruding part is located above the recessed part, the soles of the operator's shoes step on the protruding part and will not step on the grains, avoiding the risk of falling and improving safety.

[0008] In the above-mentioned grain surface walkway board, the protruding part is higher than the upper surface of the board body, and the recessed part is lower than the upper surface of the board body. This kind of structure ensures the formation of ventilation holes, and at the same time enables the protruding part to better contact the soles of the operator's shoes, enables the recessed part to better press the grains, ensures the stability of the grain surface walkway board, and improves safety.

[0009] In the above-mentioned grain surface walkway board, the middle of the protruding part is flat, and both ends of the protruding part are inclined downward obliquely from the inside to the outside. The middle of the protruding part is flat and occupies a relatively long length, providing sufficient contact area with the soles of the operator's shoes, ensuring the strength of the grain surface walkway board, and making the operator walk smoothly on the grain surface walkway board.

[0010] In the above-mentioned grain surface walkway board, the connection parts at both ends of the protruding part are in arc transition. This makes the connection part transition smoothly, improves the strength of the protruding part, and thus improves the strength of the grain surface walkway board.

[0011] In the above-mentioned grain surface walkway board, the middle of the recessed part is flat, and both ends of the recessed part are inclined upward obliquely from the inside to the outside. The middle of the recessed part is flat and occupies a relatively long length, providing sufficient contact area with the grains, and making the grain surface walkway board placed stably.

[0012] In the above-mentioned grain surface walkway board, the connection parts at both ends of the recessed part are in arc transition. This makes the connection part transition smoothly, improves the strength of the recessed part, and thus improves the strength of the grain surface walkway board.

[0013] In the above-mentioned grain surface walkway board, the protruding part and the recessed part have the same length, and the width of the protruding part is greater than the width of the recessed part. This kind of structure can increase the contact area between the grain surface walkway board and the soles of the operator's shoes while increasing the number of ventilation holes, ensuring the strength of the grain surface walkway board and making the ventilation effect of the grain surface walkway board good.

[0014] In the above-mentioned grain surface walkway board, the width of the protruding part is 1.5 - 3 times the width of the recessed part. This kind of structure can increase the number of ventilation holes and make the ventilation effect of the grain surface walkway board good.

[0015] In the above-mentioned grain surface walkway board, the distance between two adjacent rows of ventilation structures is less than the length of the protruding part. This structure can increase the number of ventilation structures and the number of ventilation holes, making the ventilation effect of the grain surface walkway board good.

[0016] In the above-mentioned grain surface walkway board, a reinforcing rib is connected between the side of the protruding part and the side of the recessed part. The ventilation holes are strip-shaped, and the reinforcing rib is located in the middle of the ventilation holes. The setting of the reinforcing rib improves the strength, so that the protruding part and the recessed part will not be bent when stepped on by the operator.

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

[0018] 1. There is a ventilation hole between each protruding part and each recessed part of this grain surface walkway board. The number of ventilation holes is large, making the ventilation effect of the grain surface walkway board good. Moreover, the width of the protruding part is greater than the width of the recessed part, further increasing the number of ventilation holes and making the ventilation effect of the grain surface walkway board good.

[0019] 2. The ventilation holes of this grain surface walkway board are located on the side. It is not easy for grains to overflow through the ventilation holes. Even if they overflow, the overflowed grains are located in the recessed part, avoiding the operator's soles stepping on the grains and the risk of falling, and improving safety.
