Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment, specifically to a feeder hopper with good sealing performance. Background Technology

[0002] As a key piece of equipment for material conveying and processing in industrial production, the feeder's core function is to stably convey various materials such as lumps, granules, and powders to subsequent processing equipment (such as crushers, mixers, and reactors) at a preset rate. It is an important link between raw material storage and production processes.

[0003] Based on differences in conveying principles and structures, feeders can be divided into various types such as screw feeders, vibrating feeders, and belt feeders. However, regardless of the type, the feed hopper is an indispensable core component. As the first load-bearing and transitional structure for materials entering the feeder, the feed hopper directly affects the continuity and stability of material conveying and the cleanliness of the production environment.

[0004] Most traditional feed hoppers employ a semi-open structure, featuring only a simple opening, a single flip-up cover, or a seal relying solely on a single sealing ring or flat surface. During material feeding and conveying, especially when handling powdery or granular materials, the airflow generated by the material flow easily carries dust away from the feed inlet and connecting gaps. This not only leads to excessive dust concentrations in the workshop, endangering the health of operators, but also poses safety hazards such as dust explosions. Furthermore, it results in material waste and fails to meet environmental regulations for industrial production environments.

[0005] Therefore, it is necessary to invent a feeder hopper with good sealing performance to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a feeder hopper with good sealing performance. By setting a sealing sleeve and a plug-in joint structure at the contact point between the cover plate and the hopper, and using an isosceles trapezoidal shape to fit and fit, the gap between the two is tightly filled, forming the first line of sealing defense. At the same time, on the opposite sides of the two sets of cover plates, a sealing strip with a movable groove is snapped on by an installation part. The elastic deformation of the movable groove compensates for the small error when the cover plate is closed, sealing the cover plate joint and forming the second line of sealing defense. This can solve the problem of dust emission and workshop pollution caused by the simple sealing design of traditional feeder hoppers in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeder hopper with good sealing performance, comprising...

The sealing sleeve and the plug-in are plugged into each other. An installation component is horizontally fixedly connected to one side of the two sets of cover plates. A sealing strip is snapped into the outer side of the installation component through a slot. The upper part of the sealing strip has a movable groove.

[0010] Preferably, the limiting component includes a fixing plate, which is fixedly connected to the upper part of the cover plate. An operating component is slidably connected to the inner wall of the middle part of the fixing plate.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1 - Figure 3 The feeder hopper shown has good sealing performance, including a hopper 1 and a sealing component 3;

[0028] Hopper 1 is used to support the overall device, to hold and transport materials, and to provide an installation reference for components such as cover plate 2, sealing assembly 3, and limiting assembly 4. The inner wall is equipped with an auger conveyor rod, and the right side is equipped with a drive assembly to drive the auger conveyor rod to rotate. The left side is the discharge port. Two sets of cover plates 2 are rotatably connected to the upper part of hopper 1, covering the upper part of hopper 1. The upper part of cover plate 2 is fixedly connected with a handle, and the lower part of cover plate 2 is equipped with reinforcing ribs. The cover plate 2 adopts a two-set symmetrical design, which covers the upper part of hopper 1 through rotatable connection, forming a closed top cover of hopper 1, preventing dust from escaping during material transportation from the source. The upper handle is easy to open and close manually, and the lower reinforcing rib enhances the structural strength of cover plate 2 itself, avoiding deformation due to material impact or frequent use, and ensuring the long-term effective cooperation of sealing assembly 3. The upper part of cover plate 2 is equipped with limiting assembly 4.

[0029] like Figure 3 , Figure 4 and Figure 6 As shown, the sealing assembly 3 has a contact point between the cover plate 2 and the hopper 1. The sealing assembly 3 includes a sealing sleeve 31, which is fixedly connected to the lower inner wall of the cover plate 2 and forms an insertion fit with the upper plug-in part 32 of the hopper 1. It is a sealing barrier at the contact point between the cover plate 2 and the hopper 1. The upper inner wall of the hopper 1 is fixedly connected to the plug-in part 32, and the sealing sleeve 31 and the plug-in part 32 are inserted into each other. The cross-section of the plug-in part 32 is set as an isosceles trapezoid. A slot that matches the shape of the plug-in part 32 is opened in the lower middle part of the cross-section of the sealing sleeve 31. The isosceles trapezoidal cross-section design allows for automatic alignment during insertion, improves assembly accuracy, enhances sealing effect, and ensures that the airflow generated by the material flow will not escape from the joint between the two. The two sets of cover plates 2 are opposite to each other. One side is horizontally fixedly connected to an installation component 33, which is provided in multiple sets and spaced apart. It is composed of a cylinder and a long strip plate and serves as the installation carrier for the sealing strip 34. The sealing strip 34 is quickly snapped and fixed through the outer groove 35, which not only ensures that the sealing strip 34 is firmly installed, but also facilitates replacement and maintenance after wear. The outer side of the installation component 33 is snapped with the sealing strip 34 through the groove 35. The sealing strip 34 is used to seal the joint when the two sets of cover plates 2 are closed. The upper part of the sealing strip 34 has a movable groove 36, which serves as an elastic adjustment structure for the sealing strip 34. It compensates for the small error when the cover plate 2 is closed by its own deformation, so that the sealing strip 34 always fits tightly against the joint of the two sets of cover plates 2, thereby enhancing the adaptability and reliability of the seal.

[0030] like Figure 1 , Figure 3 and Figure 5As shown, the limiting component 4 includes a fixing plate 41, which is fixedly connected to the upper part of the cover plate 2, providing installation and sliding support for components such as the operating component 44 and the guide rod 42. The operating component 44, consisting of a handle and a long rod, is slidably connected to the inner wall of the middle part of the fixing plate 41. By pulling the handle, the limiting rod 43 is moved. The end of the operating component 44 away from the fixing plate 41 is fixedly connected to the limiting rod 43, which is used to lock the closed state of the cover plate 2. When the cover plate 2 is closed, the limiting rod 43 is inserted into the L-shaped limiting groove 46 and tightened to ensure the continuous effectiveness of the sealing structure. The limiting groove 46 is opened on the outer side of the hopper 1, which cooperates with the limiting rod 43 to lock the cover plate 2. The limiting rod 43 and the limiting groove 46 are inserted and cooperated.

[0031] like Figure 1 , Figure 3 and Figure 5 As shown, a guide rod 42 is fixedly connected to the upper part of the limiting rod 43. The guide rod 42 is slidably connected to the inner wall of the fixed plate 41, serving as a guide to ensure that the limiting rod 43 moves in a straight line during sliding. The limiting rod 43 and the fixed plate 41 are elastically connected by an elastic element 45, which is a spring, providing elastic preload to the limiting rod 43. When the limiting rod 43 is inserted into the limiting groove 46, the tension of the elastic element 45 keeps the limiting rod 43 tightly against the inner wall of the limiting groove 46, preventing loosening and enhancing the locking stability; at the same time, it provides reset assistance when the operating element 44 drives the limiting rod 43 to disengage. The limiting groove 46 is L-shaped, and the cross-section of the fixed plate 41 is L-shaped. The sealing sleeve 31 and the plug-in 32 are U-shaped.

[0032] The working principle of this utility model is as follows: First, add material into the hopper 1. After the material is added, close the two sets of cover plates 2. The sealing sleeve 31 at the bottom of the cover plate 2 is connected to the plug-in part 32 on the upper inner wall of the hopper 1. Since the cross section of the plug-in part 32 is an isosceles trapezoid and the sealing sleeve 31 is provided with a matching slot, the two are automatically guided and fitted when they are plugged in, tightly filling the gap between the cover plate 2 and the edge of the hopper 1, forming the first sealing defense line.

[0033] Meanwhile, the sealing strips 34 on opposite sides of the two sets of cover plates 2 are fixed by the slots 35 on the mounting parts 33. The movable grooves 36 on the upper part of the sealing strips 34 adapt to the closing of the cover plates 2, tightly fitting the joint of the two sets of cover plates 2, forming a second sealing line. The double sealing effectively prevents dust from escaping during material transportation.

[0034] During the closing process of cover plate 2, the operator pulls the operating component 44, which causes the limiting rod 43 and guide rod 42 to slide and compress the spring. After cover plate 2 is closed, the operator releases the operating component 44, and the elastic force of the elastic component 45 causes the limiting rod 43 to be locked in the transverse section of the limiting groove 46, thus firmly fixing cover plate 2.

[0035] When the feeder is working, the airflow generated by the material flowing in the hopper 1 is blocked by the double sealing structure, and dust cannot leak from the contact point between the cover plate 2 and the hopper 1 or from the seam between the cover plates 2, thus achieving efficient sealed operation of the feed hopper 1.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
