Description
Technical Field
[0001] The utility model relates to the technical field of elevators, in particular to a feed inlet of a bucket elevator. Background Art
[0002] Bucket elevators are divided into three types: ring chain, plate chain and belt. Among them, the plate chain elevator uses the form of chain transmission, which has higher transmission stability and impact resistance than elevators using other transmission forms. Therefore, it is widely used in the building materials production industry for material transportation in scenarios where the incoming materials are unstable and have impacts. Most of the materials in this scenario are a mixture of materials in various forms such as lump materials, granular materials, and powder materials, and have strong abrasiveness. If the feed inlet of the plate chain elevator is not specially treated, it is very easy to be worn through by the materials, resulting in dust emission at the site and transportation failures.
[0003] To solve the above problems, some bucket elevators use wear-resistant materials added to the inner wall of the feed inlet. However, the price of wear-resistant materials is often relatively high, and over time, the wear-resistant materials will still be worn through; during the operation of the equipment, it is also impossible to timely check the wear condition of the inner wall of the feed inlet. If not replaced in time, the above problems will still occur. Therefore, this method has relatively high manufacturing and maintenance costs. In this regard, currently, most of the feed inlets of plate chain elevators are configured with a right-angle inlet connected to the tail of the machine. An inclined plate is provided at the bottom on the side of the feed inlet far from the tail of the machine, and a grille is provided on the horizontal plane of the bottom wall of the feed inlet, so that there is a layer of accumulated material at the bottom of the feed inlet, forming a form of material grinding material, so as to achieve the effect of preventing the inner wall of the feed inlet from being worn through by the material. However, for this form of feed inlet, when the material enters the tail of the machine from the feed inlet, the horizontal velocity component is very small, so that the horizontal included angle of the vast majority of the materials entering the tail of the machine is too large, and most of the materials directly fall to the bottom of the tail of the machine without entering the hopper, resulting in material accumulation at the tail of the machine, increasing the excavation power consumption of the hopper, and easily causing equipment failures.

These embodiments are implemented on the premise of the technical solution of the present utility model, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present utility model is not limited to the following embodiments.
[0021] Refer to Figures 1 to 5The present embodiment discloses a feed port of a bucket elevator, wherein the feed port 1 is arranged on one side of the tail 2 of the bucket elevator, the top of the feed port 1 is open to form a feed end, the end of the feed port 1 facing the tail 2 is the rear end, the end away from the tail 2 is the front end, the rear end of the feed port 1 is open to form a discharge end, the front end of the feed port 1 is closed by the front end side plate 3, the bottom end of the feed port 1 is closed by the feed port bottom plate 4, the front end side plate 3 and the feed port bottom plate 4 are transitionally connected by an inclined plate 5, wherein the front end side plate 3, the inclined plate 5 and the feed port bottom plate 4 can be integrally formed, and are formed by bending a whole piece of complete plate. An adjusting plate 6 is rotatably connected to the inner side of the inclined plate 5, and the bottom end of the adjusting plate 6 is rotatably connected to the feed port 1 by a hinge shaft 7 extending left and right, and the left and right ends of the hinge shaft 7 are respectively extended outward from the left and right ends of the feed port 1 to form threaded ends, and the hinge shaft 7 and the feed port 1 are locked by screwing nuts 8 on the left and right threaded ends of the hinge shaft 7. An adjusting plate grille 9 is provided on the side of the adjusting plate 6 facing the tail 2, and a bottom plate grille 10 is provided on the top surface of the feed port bottom plate 4. The adjusting plate 6 is driven to rotate around the axis of the hinge shaft 7 by adjusting the driving structure, thereby realizing the adjustment of the inclination angle of the adjusting plate 6 relative to the horizontal plane.
[0022] Among them, the adjustment driving structure includes a push rod 11, and slide rails 12 are respectively provided at the left and right ends of the adjustment plate 6 on the side facing away from the tail 2. A strip slide groove 13 is opened on the slide rail 12. The left and right ends of the push rod 11 are cross-arranged in the strip slide grooves 13 of the two slide rails 12, and the push rod 11 can slide in the strip slide grooves 13 of the slide rails 12. A push rod handle 14 perpendicular to the push rod 11 is provided in the middle section of the push rod 11. The push rod handle 14 extends horizontally in the front and rear directions. The front end of the push rod handle 14 passes outward from the inclined plate 5 and is locked relative to the position of the inclined plate 5 through a locking structure. By pushing and pulling the push rod handle 14 forward and backward, the adjustment plate 6 is driven to rotate around the axis of the hinge shaft 7.
[0023] The locking structure includes a push rod fixing seat 15, which is fixed on the outer side of the inclined plate 5 and extends vertically downward. The push rod fixing seat 15 is provided with a through hole for the push rod handle 14 to pass through. The front section of the push rod handle 14 is a threaded section. Two locking nuts 8 are threadedly sleeved on the threaded section of the push rod handle 14. The two locking nuts 8 are respectively located at the front and rear sides of the push rod fixing seat 15. A limiting cylinder 16 is also fixed on the outer side of the inclined plate 5. The push rod handle 14 passes through the inside of the limiting cylinder 16. Among the two locking nuts 8, the locking nut 8 located at the rear side of the push rod fixing seat 15 is a rear locking nut 17, and the other locking nut 8 is a front locking nut 18. The rear locking nut 17 is located between the push rod fixing seat 15 and the limiting cylinder 16, and the front and rear positions of the rear locking nut 17 are limited by the push rod fixing seat 15 and the limiting cylinder 16, so that the rear locking nut 17 can only rotate but cannot move forward and backward.
[0024] The rear inspection door 19 is detachably connected to the front end side plate 3. The rear inspection door 19 can be designed in a structure that can be opened and closed. An inspection opening is provided on the front end side plate 3, and a door frame is provided on the front end side plate 3 around the inspection opening. The rear inspection door 19 and the door frame can be detachably connected by means of screw connection. When the process changes and the inclination angle of the adjusting plate 6 needs to be adjusted, the rear inspection door 19 can be opened to clean the materials accumulated in the gap between the front side of the adjusting plate 6 and the inclined plate 5, so as to readjust the angle of the adjusting plate 6.
[0025] During operation, the materials fall into the feed inlet 1 from the feed end of the feed inlet 1. Since the adjusting plate grille 9 is provided on the adjusting plate 6 and the bottom plate grille 10 is provided on the bottom plate of the feed inlet 4, combined with the viscosity and adsorption force of the materials themselves, the materials that fall first will accumulate on it, forming a material accumulation layer, so that the subsequent incoming materials impact and abrade the previously formed material accumulation layer, rather than abrading the inner wall of the feed inlet 1, thus protecting the feed inlet 1. The height of the material accumulation layer and the inclination angle of the surface of the material accumulation layer will vary depending on the inclination angle of the adjusting plate 6. When the material accumulation layer is formed at the bottom of the feed inlet 1, the materials that fall later will first fall onto the material accumulation layer and then fall into the hopper 20 inside the tail 2 through the discharge end of the feed inlet 1. When the height of the material accumulation layer and the inclination angle of the surface of the material accumulation layer reach appropriate values, more materials can fall into the hopper 20 inside the tail 2 from the discharge end of the feed inlet 1. Therefore, by changing the inclination angle of the adjusting plate 6, the shape of the material accumulation layer at the bottom of the feed inlet 1 can be adjusted, so that more materials can fall into the hopper 20 inside the tail 2 from the discharge end of the feed inlet 1, thereby reducing the accumulation of materials inside the tail 2.
[0026] When it is necessary to adjust the tilt angle of the adjusting plate 6, first open the inspection door 19 at the tail of the machine, and clean the materials accumulated in the gap between the front side of the adjusting plate and the tilting plate 5 to facilitate the smooth rotation of the adjusting plate 6 subsequently. Then loosen the nuts 8 at both the left and right ends of the hinge shaft 7 to unlock the hinge shaft 7. After that, loosen and remove the front locking nut 18 on the push rod handle 14, and use a wrench to rotate the rear locking nut 17, thereby driving the push rod handle 14 to move in the front-rear direction. The push rod handle 14 pulls the push rod 11 to move back and forth together. The push rod 11 drives the two slide rails 12 to act, thereby driving the adjusting plate 6 to rotate around the axis line of the hinge shaft 7, realizing the adjustment of the tilt angle of the adjusting plate 6. When the appropriate tilt angle is adjusted, then screw on the front locking nut 18 on the push rod handle 14 and make the front locking nut 18 closely adhere to the push rod fixing seat 15, then the front-rear position of the push rod handle 14 can be locked. After that, tighten the nuts 8 at both the left and right ends of the hinge shaft 7 to lock the hinge shaft 7, further locking the position of the adjusting plate 6. After the tilt angle of the adjusting plate 6 is adjusted and fixed at a certain angle, when adding materials subsequently, the space between the front side of the adjusting plate 6 and the tilting plate 5 will be filled with accumulated materials, thus forming a support buffer for the adjusting plate 6, which is beneficial to resisting the impact of the incoming materials and reducing the damage to the equipment.
[0027] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
