[0002] A hopper is a large mechanical platform designed specifically for large construction sites, factories, and other locations requiring the unloading of large quantities of materials. Therefore, the structural components used on a hopper have high requirements for structural strength and flatness. Platform-type hoppers are often used in large construction sites and mines, resulting in a larger overall size and higher center of gravity for the platform. To ensure strength and flatness, a central structure must be used as a benchmark to guarantee the precision and strength of each component. However, existing platform structures suffer from poor structural strength, reliability, and stability. Utility Model Content

The two ends of the diagonal braces are respectively connected to two adjacent side beams on the outer frame.

[0008] Furthermore, the diagonal tie rod is provided at the connection between the connecting beam and the side beam.

[0009] Furthermore, the intermediate body also includes a grid-like reinforcing member on the intermediate frame. The reinforcing member is provided with multiple longitudinal beams and transverse beams for connecting the outer frame and the inner frame. The reinforcing member is provided with a diagonal beam for connecting the intermediate frame and the boss frame at the position corresponding to the diagonal tie rod. The length direction of the diagonal beam is perpendicular to the length direction of the diagonal tie rod.

[0010] Furthermore, the inner frame has a "well" shaped structure, the boss frame has a rectangular structure, and eight connecting beams are evenly distributed at the four corners of the boss frame.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] A boss structure for mounting and positioning a discharge hopper, such as Figures 1 to 3As shown, the system includes an outer frame and an inner frame. The outer frame is fitted over the outer frame, and the inner frame and outer frame are connected by an intermediate body. At least four uprights 1 for connecting the unloading hopper are evenly arranged around the outer frame. The inner frame includes a boss frame 7, the upper surface of which is higher than the upper surface of the outer frame. At least eight connecting beams 3 are evenly arranged around the boss frame 7, each connecting beam 3 being connected to the outer frame at one end and to the boss frame 7 at the other end. The intermediate body includes an intermediate frame 4 disposed between the outer frame and the inner frame, and the intermediate frame 4 is connected to the connecting beams 3.

[0027] For example, the outer frame, inner frame, and intermediate body can all be made of steel structural components to ensure the structural strength of this boss structure, and all components can be fixed together by welding to further improve the structural strength of the boss structure. By connecting the intermediate frame 4 to the connecting beam 3, a stable support structure can be formed between the outer frame and the inner frame, reducing the probability of deformation of the connecting beam 3 and improving the overall structural strength of this boss structure.

[0028] Preferably, the outer frame is rectangular, and four uprights 1 are provided at the four corners of the outer frame. For example, four uprights 1 at the four corners can meet the installation requirements of the subsequent unloading hopper, thereby achieving stable support for the unloading hopper. Furthermore, those skilled in the art can also select other shapes of outer frames and adjust the number of uprights 1 according to actual needs, which will not be elaborated here.

[0029] In practical applications, the support legs on the unloading hopper can be welded to the column 1, and support legs can also be welded and fixed below the column 1 to achieve stable support for the unloading hopper. Meanwhile, the unloading pipe in the middle of the hopper can pass through the boss frame 7 in the middle of the inner frame. The boss frame 7 effectively positions the unloading pipe and provides effective support for the lower end of the unloading hopper, which helps improve the stability and reliability of the unloading hopper during use.

[0030] Preferably, the intermediate frame 4 is provided with diagonal braces 8 at the four corners corresponding to the outer frame. The intermediate frame 4 is provided with mounting holes 14 for installing the diagonal braces 8. The two ends of the diagonal braces 8 are respectively connected to two adjacent side beams 2 on the outer frame. For example, both ends of the diagonal braces 8 can be welded and fixed to the side beams 2 of the outer frame, and the diagonal braces 8 can also be welded and fixed to the intermediate frame to improve structural strength. Those skilled in the art can also choose other methods to install the diagonal braces 8 according to actual needs to achieve a stable connection between the diagonal braces 8 and the side beams 2.

[0031] By installing diagonal bracing beams at the four corners of the outer frame, the tensioning effect of these beams effectively prevents deformation at the corners, thereby improving the overall structural strength of the outer frame. Combined with the intermediate body and inner frame as the central skeleton, the overall structural strength and stability of this boss structure are further enhanced.

[0032] In practical applications, the diagonal brace 8 is installed at the connection between the connecting beam 3 and the edge beam 2. For example, the diagonal brace 8 can also be welded and fixed at the connection between the connecting beam 3 and the edge beam 2, so that the diagonal brace can not only achieve tension and fixation of the external frame, but also improve the structural strength of the connection between the connecting beam 3 and the edge beam 2, and prevent the connecting beam 3 from deforming or breaking under stress.

[0033] Preferably, the intermediate body also includes a grid-like reinforcing member provided on the intermediate frame 4. The reinforcing member is provided with a plurality of longitudinal beams 6 and transverse beams 5 for connecting the outer frame and the inner frame. The reinforcing member is provided with a diagonal beam 9 for connecting the intermediate frame 4 and the boss frame 7 at the position corresponding to the diagonal tie rod 8. The length direction of the diagonal beam 9 is perpendicular to the length direction of the diagonal tie rod 8.

[0034] For example, the reinforcing member can be welded and fixed to the intermediate body, and is positioned above the intermediate body to improve the load-bearing stability of the inner frame for the unloading hopper. The crossbeams 5 and longitudinal beams 6 can also be welded and fixed to their respective components. Using a mesh-like reinforcing member not only helps reduce weight but also strengthens the stability of the connection between the intermediate frame 4 and the inner and outer frames. Furthermore, by incorporating inclined beams 9 on the reinforcing member, which can cooperate with inclined tie rods 8, the overall structural strength of the intermediate body is further ensured.

[0035] Preferably, the inner frame has a grid-like structure, the boss frame 7 is a rectangular structure, and eight connecting beams 3 are evenly distributed at the four corners of the boss frame 7. Compared with other structures, the grid-like inner frame effectively balances structural strength and mass, which helps to reduce the mass of this boss structure and improve its structural strength.

[0036] Preferably, the connecting beam 3 has a trapezoidal transition section 13 at one end facing the boss frame 7, and a connecting section 12 at the other end. For example, the transition section 13 can be welded to the boss frame 7, and the transition section 13 can be a right-angled trapezoid with its hypotenuse facing upwards, to achieve a smooth connection between the boss frame 7 and the connecting beam 3, ensuring the structural strength at the point where the boss frame 7 and the connecting beam 3 meet. Meanwhile, the connecting section 12 can be welded to the side beam 2 of the outer frame.

[0037] Preferably, a plurality of T-beams 11 are provided on the inner side of the boss frame 7. Each T-beam 11 is evenly arranged around the circumference of the boss frame 7, and each T-beam 11 is vertically mounted on the boss frame 7. The flanges of each T-beam 11 face the center of the boss frame 7, and the webs are all mounted on the boss frame 7. Exemplarily, the T-beams 11 are welded and fixed to the boss frame 7. By providing multiple T-beams 11, not only can the structural strength of the boss frame 7 be enhanced, but it can also provide good support for the unloading pipe on the unloading hopper.

[0038] Preferably, the column member 1 is provided with connectors 10 at positions corresponding to the upper and lower parts of the outer frame. One end of each connector 10 is connected to the column member 1, and the other end is connected to the side beam 2 of the outer frame. For example, the connector 10 can be an I-beam structure or a double-I-beam. The two flanges of the connector 10 are respectively positioned on the inner and outer sides of the side beam 2. One end of the connector 10 is welded and fixed to the side beam 2, and the other end is welded and fixed to the column member 1. By providing connectors 10, the structural strength at the connection between the column member 1 and the outer frame is improved.

[0039] This utility model provides a boss structure for installing and positioning a discharge hopper, which has the advantages of high structural strength, good stability and reliability. By adopting a structure combining an outer frame, an inner frame and an intermediate body, a sturdy and durable frame structure can be formed. The uprights on it can connect to the discharge hopper support legs and fixed support legs, and the boss body on the inner frame can form a raised flat platform, located at a higher position than the discharge point, so as to allow the material to flow naturally. This boss structure can play a good supporting role for the discharge hopper.
