Description

Technical Field

[0001] This utility model relates to the field of material guide groove sealing box technology, and in particular to an electric flip-type tail sealing box. Background Technology

[0002] Belt conveyors are a common material conveying equipment, widely used in industries such as metallurgy, coal, transportation, power, building materials, chemicals, light industry, grain, and machinery. In power companies, they are important transportation equipment for transporting coal. As an important component of the conveying system, the guide trough is generally installed at the receiving point of the belt conveyor to prevent material spillage and suppress dust.

[0003] During operation, material spillage may occur. Usually, after spillage, employees are sent to shovel the material onto the conveyor belt. However, the feed chute is often tightly sealed, making it difficult to find a good place to shovel the material. Therefore, a sealing plate can be installed at the feed port of the sealed box to facilitate the refeeding of materials. For example, the prior art Chinese patent announcement number "CN210635277U" discloses a passable tail sealing box, including a sealed box body, an inner sealing curtain, an electric push rod, and a tail plate. The outlet end of the sealed box body is provided with an inner sealing curtain. The rod of the electric push rod is fixed to the top of the sealed box body. The push rod end of the electric push rod is hinged to the middle of the outer wall of the tail plate. The outer wall of the tail plate is hinged to the top of the sealed box body, and the inner wall of the tail plate is fastened to the inlet end of the sealed box body.

[0004] In actual operation, the tailplate and the shaft end of the electric push rod are fixedly connected by a fixing lug. Considering that the tailplate itself may be damaged after long-term use, and that the tailplate sealing surface is equipped with a sealing gasket, it is not convenient to disassemble and assemble, which may affect the efficiency of assembly and maintenance. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the inconvenience of disassembling and assembling the tail plate, which easily affects the efficiency of assembly and maintenance, and to propose an electric flip-type tail sealing box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an electric flap-type tail sealing box, including a sealing box and a flap installed at the loading port of the sealing box. The sealing box is fixedly connected to the receiving end of the guide chute. The flap is covered at the loading port of the sealing box by a drive assembly. The drive assembly includes a connecting arm, and the connecting arm and the flap are detachably connected by a fixing assembly.

[0008] Furthermore, the drive assembly also includes a motor, the motor is fixedly connected to the side of the sealing box, a shaft is fixedly connected to the shaft end of the motor, the shaft is rotatably connected to the top of the sealing box through a connecting seat, and at least one connecting arm is fixedly connected to the periphery of the shaft.

[0009] Furthermore, the fixing component includes a connecting rod with a T-shaped cross-section. The rod-shaped portion is slidably connected to the flap via a compression spring. The two ends of the compression spring abut against the inner side of the flap and the annular protrusion of the connecting rod, respectively.

[0010] Furthermore, the connecting rod has a stop portion on the periphery of one end near the annular protrusion, and a cavity is provided inside. The cavity passes through the connecting rod and the two sides of the stop portion to form corresponding deformation grooves. The stop portion can stop on the outer side of the flap through the deformation grooves.

[0011] Furthermore, the free end of the connecting arm connects to the side to form a limiting groove, and the end of the limiting groove has a relief portion, and the stop portion can be accommodated in the relief portion;

[0012] The rod-shaped portion of the connecting rod is slidably connected within the limiting groove, and a fixing member is also fixedly connected to the end of the rod-shaped portion of the connecting rod.

[0013] Furthermore, the bottom of the two arms of the fixing member are fixedly connected to the limiting protrusions, and the limiting protrusions are movably inserted into the limiting holes at the ends of the connecting arms;

[0014] The end of the limiting protrusion has an arc-shaped structure and slides against the end of the connecting arm.

[0015] The present invention proposes an electric flip-type tail sealing box, which has the following advantages: In this invention, the flip-type valve can be electrically controlled to flip by a drive component, and the overflow material can be easily re-discharged by opening and closing the loading port of the sealing box, thereby speeding up the overflow handling efficiency. In addition, the flip-type valve and the drive component are detachably connected by a fixing component, which on the one hand improves the assembly efficiency of the flip-type valve and facilitates subsequent maintenance, and on the other hand, the fixing component can prevent the fixing part from resetting by pulling the connecting rod to drive the stop part to stop on the surface of the flip-type valve. This allows the disassembly and assembly of the flip-type valve to be carried out by one person independently. The structure is simple and practical. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 An electric flip-type tail sealing box includes a sealing box 1 and a flip plate 2 installed at the feeding port of the sealing box 1. The sealing box 1 is fixedly connected to the receiving end of the guide trough. The flip plate 2 is covered at the feeding port of the sealing box 1 by a drive assembly 3. The drive assembly 3 includes a connecting arm 31. The connecting arm 31 and the flip plate 2 are detachably connected by a fixing assembly 4.

[0024] In some embodiments, the connection method and specific structure between the material guide trough and the sealing box 1 can refer to the dust suppression material guide trough device in the prior art. At least one set of dust suppression curtains can be set inside the sealing box 1. When the flap 2 is opened to deliver overflow material, the dust suppression curtains work together to use the airflow generated when the material falls to suppress the dust in the material guide trough and reduce leakage.

[0025] Furthermore, the drive assembly 3 also includes a motor 32, which is fixedly connected to the side of the sealing box 1. A shaft 33 is fixedly connected to the shaft end of the motor 32. The shaft 33 is rotatably connected to the top of the sealing box 1 through a connecting seat, and at least one connecting arm 31 is fixedly connected to the periphery of the shaft 33.

[0026] It should be added that a sealing gasket can be installed between the tail plate 2 and the loading port of the sealing box 1 to improve the sealing performance. The motor 32 is connected to the control unit, and the control unit realizes the electric control of the flip plate 2 to flip.

[0027] Specifically, after receiving the instruction, the control unit, in conjunction with sensors (such as encoders), checks whether the motor shaft end is in position, then calculates and adjusts the signal sent to the driver, which provides a suitable current to precisely control the movement of the motor and drive the flap to flip. This technique is existing technology and will not be elaborated upon.

[0028] Furthermore, the fixing component 4 includes a connecting rod 41 with a T-shaped cross-section. The rod-shaped part is slidably connected to the flap 2 via a compression spring 42. The two ends of the compression spring 42 abut against the inner side of the flap 2 and the annular protrusion of the connecting rod 41, respectively.

[0029] More specifically, the connecting rod 41 has a stop portion 43 on the periphery of one end near the annular protrusion, and a cavity is provided inside. The cavity passes through the connecting rod 41 and the two sides of the stop portion 43 to form corresponding deformation grooves 44. The stop portion 43 can stop on the outer side of the flap 2 through the deformation grooves 44.

[0030] In general, the free end of the connecting arm 31 forms a limiting groove 45 on the side, and the end of the limiting groove 45 has a relief portion 46, and the stop portion 43 can be accommodated in the relief portion 46.

[0031] The rod-shaped portion of the connecting rod 41 is slidably connected within the limiting groove 45, and a fixing member 47 is fixedly connected to the end of the rod-shaped portion of the connecting rod 41.

[0032] Finally, the bottom of the two arms of the fixing member 47 is fixedly connected to the limiting protrusion 48, and the limiting protrusion 48 is movably inserted into the limiting hole 49 at the end of the connecting arm 31.

[0033] The end of the limiting protrusion 48 has an arc-shaped structure and slides against the end of the connecting arm 31.

[0034] In this embodiment, as Figure 3 , 5 As shown, under normal circumstances, the flap 2 and the connecting arm 31 are connected by a movable plug-in connection. In actual operation, the connecting arm 31 is slidably connected to the rod-shaped part of the connecting rod 41 through the limiting groove 45. At the same time, the end of the connecting arm 31 slides against the limiting protrusion 48. The limiting protrusion 48 moves upward under force, causing the compression spring 42 to be compressed.

[0035] When the limiting protrusion 48 is inserted into the limiting hole 49, the compression spring 42 drives the connecting rod 41 to reset. The limiting protrusion 48, together with the limiting groove 45, can connect and fix the flap 2 and the connecting arm 31.

[0036] Similarly, after the lifting and fixing component 47 drives the limiting protrusion 48 to disengage from the limiting hole 49, the flip plate 2 can be separated.

[0037] It is worth mentioning that, under normal circumstances, when the limiting protrusion 48 disengages from the limiting hole 49 when the fixing member 47 is pulled up, the stop part 43 abuts against the inner side of the flip plate 2. In order to prevent one fixing member 47 from resetting and affecting the unlocking of the remaining fixing members 47, the fixing member 47 can be pulled up again to drive it to continue to move upward.

[0038] The stop part 43 deforms and makes room against the flap 2 under the action of the deformation groove 44. When the stop part 43 stops against the outer side of the flap 2, the fixing part 47 can be prevented from resetting. At this time, the stop part 43 is in the relief part 46 to prevent jamming.

[0039] Working method: The flap 2 and the connecting arm 31 are connected by a movable plug-in connection. The connecting arm 31 is slidably connected to the rod-shaped part of the connecting rod 41 through the limiting groove 45. At the same time, the end of the connecting arm 31 slides against the limiting protrusion 48. When the limiting protrusion 48 is inserted into the limiting hole 49, the compression spring 42 drives the connecting rod 41 to reset. The limiting protrusion 48 and the limiting groove 45 can connect and fix the flap 2 and the connecting arm 31.

[0040] Similarly, after the lifting and fixing component 47 drives the limiting protrusion 48 to disengage from the limiting hole 49, the flip plate 2 can be separated.

[0041] The stop part 43 deforms and makes room against the flap 2 under the action of the deformation groove 44. When the stop part 43 stops against the outer side of the flap 2, the fixing part 47 can be prevented from resetting.

[0042] Finally, the control unit sends an electrical signal to the motor 32, which drives the shaft 33 to cooperate with the connecting arm 31 to drive the flap 2 to open and close.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
