Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a dust-proof drop hopper which is easy to process and prevents leakage. Background Art

[0002] In the process of sand and gravel stacking, sand and gravel are generally transported to the stockpile yard by conveyor belts. If they fall directly from a high place, a lot of dust will be generated. Therefore, our company has developed a dust-proof dropping equipment. Sand and gravel fall from a retractable pipe with a dropping hopper at the bottom. The dropping hopper covers the sand and gravel piled at the bottom, so that dust can be prevented from leaking during the dropping process. As the sand and gravel accumulate, the dropping hopper is gradually lifted and the pipe is retracted upward to keep the dropping hopper covering the sand and gravel pile at all times.

[0003] When sand and gravel are piled up, they are cone-shaped. In theory, the hopper should be truncated. However, the truncated cone needs to be cut into sectors by a large steel plate and then processed by a plate rolling machine. Not only is the cost high, but the process is also complicated.

[0004] Our company initially used multiple steel plates welded into a prism shape. Although the process was simplified and the cost was reduced, the contour of the bottom was not circular, and the corners were not well sealed with the sand and gravel pile, so dust could easily leak from here. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a dust-proof material hopper which is easy to process and prevents leakage, so as to solve the technical problems in the background technology.

[0006] The technical solution of the utility model is:

[0007] A dust-proof hopper which is easy to process and prevents leakage comprises a cover body, which is in the shape of a prism and is assembled and welded by a plurality of skirt plates; a top plate with a regular polygonal outer periphery is welded on the top of the cover body, and a circular feeding hole is provided in the center of the top plate; guide plates are welded on the bottom of the skirt plates of the prism, and the guide plates form a guide cover, which is in the shape of an inverted prism, and arcuate edges are cut at the bottom of the guide plates, and the vertical projection of the arcuate edges at the bottom of the guide cover after being connected is circular.

[0008] Furthermore, the number of skirt plates and guide plates are 8 to 10.

[0009] Furthermore, the inclination angle between the guide plate and the horizontal plane is 40°-50°.

[0010] The utility model is beneficial in that:

[0011] The utility model processes the cover body into a prism shape, so that multiple horizontal skirt plates can be used for welding. Compared with the truncated cone-shaped cover body, a plate rolling machine is not required, and a flat plate can be cut. The process is simpler and the cost is lower. However, the bottom corners of the prism-shaped cover body are not well sealed with the bottom sand and gravel, and dust will leak out from here. Therefore, the utility model uses a guide plate to form a guide cover, and an arc edge is cut at the bottom of the guide plate. After the arc edges are connected, the vertical projection at the bottom of the guide cover is a circle, so that the bottom can form a good seal with the truncated cone-shaped sand and gravel at the bottom to prevent dust from leaking out.

[0017] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] like Figure 1-4 As shown:

[0019] A dust-proof hopper which is easy to process and prevents leakage, comprises a cover body 2, the cover body 2 is in the shape of a prism, and is assembled and welded by a plurality of skirt plates 21; a top plate 1 with a regular polygonal outer periphery is welded on the top of the cover body 2, and a circular feeding hole 11 is provided in the center of the top plate 1; guide plates 31 are welded on the bottom of the skirt plates 21 of the prism, and the guide plates 31 form a guide cover 3, which is in the shape of an inverted prism, and an arcuate edge 311 is cut out at the bottom of the guide plate 31, and the vertical projection of the arcuate edge 311 at the bottom of the guide cover 3 after being connected is circular.

[0020] The utility model processes the cover body 2 into a prism shape, so that multiple horizontal skirt plates 21 can be used for welding. Compared with the truncated cone-shaped cover body 2, a plate rolling machine is not required, and a flat plate can be cut, so the process is simpler and the cost is lower. However, the bottom corners of the prism-shaped cover body 2 are not well sealed with the bottom sand and gravel, and dust will leak out from here. Therefore, the utility model uses a guide plate 31 to form a guide cover 3, and cuts an arc edge 311 at the bottom of the guide plate 31. After the arc edge 311 is connected, the vertical projection at the bottom of the guide cover 3 is a circle, so that the bottom can form a good seal with the truncated cone-shaped sand and gravel at the bottom to prevent dust from leaking out.

[0021] As an optimized solution, the number of skirt plates 21 and guide plates 31 are 8-10, which can take into account both the processing cost and the uniformity of the sand and gravel bulk materials. The inclination angle between the guide plates 31 and the horizontal plane is 40°-50°, which can minimize the width of the guide plates 31 and avoid material obstruction.

[0022] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
