Description

Technical Field

[0001] The utility model relates to the technical field of port grain silos, and particularly relates to a port grain silo with a wear-resistant funnel. Background Technique

[0002] A grain silo is a facility for storing grains. It is usually made of metal or concrete and has a cylindrical or conical structure. The design of the grain silo aims to protect grains from moisture, pests and other external factors. The main advantages of the grain silo include: 1. Protecting the quality of grains: The grain silo provides a dry, ventilated and sealed environment, which helps to prevent grains from getting damp, mildewing and being damaged by pests; 2. Saving space: Since the grain silo is a vertical structure, it can save ground space and allows for better utilization of the storage site, etc.

[0003] In the Chinese utility model patent with the publication number of CN221190029U, a grain silo with a wear-resistant funnel is disclosed, which includes a silo body made of concrete. An outlet pipe is fixedly connected below the silo body, and a valve is installed on the outlet pipe. A plurality of support columns are poured at the lower surface of the silo body. Two symmetrically arranged clamping grooves are opened at the upper end of the silo body, and a connecting rod is slidably connected in the clamping grooves; in this utility model, after hanging the lifting end of the crane on the second lifting ear and then lifting the disassembly sealing cover upwards, and then taking out the connecting rod and the steel funnel below it from the silo body through the first lifting ear, and then the crane places a new steel funnel in the silo body, so as to achieve the effect of convenient replacement of the steel funnel, that is, it can provide sufficient wear-resistant protection for the lower part inside the silo body and is also convenient for replacement.

[0004] In view of the above related technologies, the inventor believes that there are the following defects: Since grain silos are often huge and too high, it is often inconvenient to use this device for wear-resistant liners, and it is also inconvenient to replace the bottom iron funnel. Sometimes collisions will occur due to the excessive height. For this reason, we propose a port grain silo with a wear-resistant funnel. Content of the Utility Model

The mating port 17 can be in mating connection with the limit port 16 on the silo main body 2, which can play a limiting role and also ensure the convenient taking of the lining plate 5 inside the rotary funnel silo shell 1, indirectly improving the replacement efficiency.

[0029] Furthermore, two connection holes 13 for mating connection with the connection holes 21 are opened on the rectangular groove 12 at the position where the first support column 4 corresponds to the connection with the rotary funnel silo shell 1. Connection holes are opened on the fixed bottom plate 14 at the end of the first support column 4 away from the silo main body 2 in an axially symmetric distribution. Two convex blocks 11 for mating connection with the sealing cover 3 are provided at the end of the first support column 4 corresponding to the silo main body 2. The fixed bottom plate 14 is perpendicular to the vertical main body of the first support column 4, and the fixed bottom plate 14 is longer and cooperates with the connection holes opened thereon, which can be firmly connected to the ground to ensure the stability of the port grain silo with a wear-resistant funnel.

[0030] Furthermore, at the position where the second support column 7 correspondingly connects to the rotary funnel silo shell 1, an axial center column 9 is provided which is in mating connection with the rotation hole 19. At one end of the second support column 7 away from the silo main body 2, connection holes which are axially symmetrically distributed are provided on the fixed bottom plate 10.

[0031] Furthermore, the iron funnel 6 is integrally a conical funnel shape. At one end of the iron funnel 6 corresponding to the connection with the lining plate 5, a mating edge 23 is provided. Inside the iron funnel 6, three second lifting lugs 24 which are axially symmetrically distributed are provided. At one end of the iron funnel 6 away from the mating edge 23, a grain outlet 25 which is in mating connection with the bottom cone angle of the rotary funnel silo shell 1 is provided. The second lifting lugs 24 facilitate the connection with external equipment and the hoisting for replacement, improving the replacement efficiency. The edge 23 facilitates the quick connection between the iron funnel 6 and the lining plate 5.

[0032] Furthermore, the lining plate 5 is integrally an annular bowl shape with openings at both ends. The external dimensions of the lining plate 5 are the same as the internal dimensions of the rotary funnel silo shell 1. The large opening end of the lining plate 5 is an inclined edge, and at the large opening end of the lining plate 5, three first lifting lugs 22 which are axially symmetrically distributed are provided. At one end of the lining plate 5 corresponding to the connection with the iron funnel 6, an annular boss which is in mating connection with the mating edge 23 is provided.

[0033] Working principle: Install the port grain silo with wear-resistant funnel correctly according to the schematic diagram, that is, fix the positions of the welding combination of the silo main body 2, the first support column 4, etc. through the fixed bottom plate 10 and the fixed bottom plate 14. Then connect the rotary funnel silo shell 1 to the axial center column 9 of the second support column 7 through the rotation hole 19, and place the lining plate 5 and the iron funnel 6 inside the rotary funnel silo shell 1. And the lining plate 5 and the iron funnel 6 are in surface contact connection, and are in surface contact connection with the shape-adapting surface inside the rotary funnel silo shell 1. And the grain outlet 25 of the iron funnel 6 passes through the funnel bottom of the rotary funnel silo shell 1 and is connected to an external valve or a transportation device. When storing grain is needed, rotate the second connection block 20 of the rotary funnel silo shell 1 to be in mating with the rectangular groove 12 of the first support column 4, and select a suitable bolt to fixedly connect the rotary funnel silo shell 1 and the first support column 4. With the mating port 17 of the rotary funnel silo shell 1 and the limit port 16 of the silo main body 2, the connection between the two is made closer. Since the transfer cycle of the port grain silo is short, the internal wear is relatively frequent and needs to be replaced frequently. Therefore, only by simply rotating the rotary funnel silo shell 1, the lining plate 5 or the iron funnel 6 can be taken out for replacement through external equipment cooperating with the first lifting lugs 22 and the second lifting lugs 24, improving the replacement speed and the working efficiency.

[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
