Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 5, the present embodiment provides a hopper connecting structure, which can be used in various types of apparatuses requiring a hopper, such as weighing machines, sieving machines, hopper feeding devices, etc., and includes a hopper 10 and a supporting plate 20, both of which are made of stainless steel plates through processes of punching, bending, etc.

The hopper 10 includes a hopper body 11 and a baffle 12 integrally connected to an upper end of the hopper body 11, but the baffle 12 may not be provided. The hopper 10 is expanded to form a strip of plate, preferably stainless steel plate, i.e. the hopper 10 is expanded to form a flat stainless steel plate. The strip-shaped plate comprises at least three side wall units which are connected in sequence and used for forming the side wall of the hopper 10, and in the embodiment, four side wall units are taken as an example for explanation. The side wall units comprise square plates 13 and isosceles trapezoid plates 14, wherein the lower bottom edges of the isosceles trapezoid plates 14 (namely, the side faces corresponding to the lower bottom edges of the isosceles trapezoids) are integrally connected with one long edges of the corresponding square plates 13 (namely, the side faces corresponding to the long edges of the rectangles), the lower bottom edges of the isosceles trapezoid plates 14 are identical to the long edges of the corresponding square plates 13 in length, and the short edges of the two adjacent side wall units on one opposite side of each square plate 13 (namely, the side faces corresponding to the short edges of the rectangles) are integrally connected. In addition, the two waists of the isosceles trapezoidal plates 14 on at least one side wall unit are integrally connected with convex buckles 15, and the convex buckles 15 are positioned on the plane where the corresponding isosceles trapezoidal plates 14 are positioned, so that a strip-shaped plate can be formed in a stamping and cutting mode.

The end parts of the head end and the tail end of the strip-shaped plate are completely welded together, and two adjacent side wall units are bent in opposite directions to enable two adjacent square plates 13 to be perpendicular to each other, meanwhile, the corresponding waists of the isosceles trapezoid plates 14 of the two adjacent side wall units are welded together to form a hopper 10 (see fig. 4), wherein each isosceles trapezoid plate 14 jointly surrounds to form a hopper body 11, each square plate 13 jointly surrounds to form a baffle body 12, the outline shapes of the cross sections of the positions of the hopper body 11 from top to bottom are the same, the outline shape of the cross section of the hopper body 11 is a regular polygon, the side walls of the hopper body 11 corresponding to the sides of the regular polygon are isosceles trapezoid plane plates (namely the isosceles trapezoid plates 14), and the outer side wall of the hopper body 11 formed after the strip-shaped plate is bent and welded is integrally connected with a convex buckle 15, of course, the convex buckle 15 can also be fixedly connected to the side wall of the hopper body, in this embodiment, the side surfaces of at least one of the flat panels corresponding to the two sides of the isosceles trapezoid are respectively provided with a convex buckle 15. The area of the profile surface of the cross section of each position of the hopper body 11 from top to bottom is gradually reduced, and the profile shape of the cross section of the surrounding baffle body 12 is the same as that of the cross section of the uppermost end of the hopper body. Preferably, in order to facilitate the bending between two adjacent side wall units, the position of the strip-shaped plate in the two adjacent side wall unit brackets is provided with a notch 16, and the notch 16 is located on one side of the strip-shaped plate away from the isosceles trapezoid plate 14.

The upper side of the male buckle 15 is provided with a clamping surface 17 which is vertically arranged with the corresponding outer side wall of the hopper body 11, and since the outer side walls of the body 11 are obliquely arranged relative to the horizontal plane, the clamping surface 17 is also necessarily obliquely arranged relative to the horizontal plane.

The supporting plate 20 is provided with a mounting hole 21 for inserting the hopper body 11, namely the supporting plate 20 is provided with a mounting hole 21 for inserting the hopper 10, the cross section of the mounting hole 21 is identical to the cross section of the hopper body 11 in contour shape, and the side wall of the mounting hole 21 is fixedly connected or integrally connected with a clamping plate 22 matched with the convex buckle 15, when in use, one end of the clamping plate 22 which is not connected with the mounting hole 21 is arranged downwards and propped against the convex buckle 15, and the clamping surface 17 is arranged obliquely relative to the horizontal plane and can play a certain guiding role, so that the hopper 10 is clamped more and more tightly with the supporting plate 20 under the action of gravity or vibration (see fig. 5).

Preferably, in this embodiment, the clamping plate 21 and the support plate 20 are stainless steel flat plates integrally connected to each other, a counter bore (not shown) is formed in the lower side surface of the support plate 20 by stamping, a boss (not shown) is naturally formed in the upper side surface of the support plate 20 at a position corresponding to the counter bore, the mounting hole 21 is formed in the boss by punching, and the cross-sectional shape of the boss is the same as the cross-sectional shape of the mounting hole. This not only helps to strengthen the support plate 20, but also helps to improve the adhesion between the sidewall of the mounting hole 21 and the hopper 10, thereby providing a dust-proof effect. It should be noted that, when the mounting hole 21 is punched, the clamping plate 21 located in the mounting hole 21 is formed at the same time, and then the clamping plate is folded along the connecting position between the clamping plate 21 and the side wall of the mounting hole 21, so that the end of the clamping plate 22 not connected with the mounting hole 21 is arranged downward, and thus the connecting position between the clamping plate 22 and the mounting hole 21 has certain elasticity, which is convenient for the clamping plate 22 to abut against the side wall of the hopper 10. In addition, the periphery of the support plate 20 is bent downward to form a guard edge 23, and the guard edge 23 can also function as a reinforcing rib.

The present invention has been described in detail with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments, and those skilled in the art can make various modifications to the present invention according to the prior art, and these all belong to the protection scope of the present invention.
