Description

Technical Field

[0001] The utility model belongs to the technical field of bridge-type grab bucket ship unloaders, and more specifically relates to a material receiving device for facilitating material receiving by a bridge-type grab bucket ship unloader. Background Art

[0002] A bridge-type grab ship unloader is a type of bridge crane that uses a mobile trolley to drive a grab bucket to grab materials from the ship's hold and unload them into an onboard hopper. It is an intermittent (or periodic) bulk material unloading machine and is primarily composed of a metal structure, mechanisms, and an electrical control system. The metal structure primarily includes the main beam, gantry, and tie rods, while the mechanisms primarily include the lifting mechanism / opening and closing mechanism, trolley running mechanism, carriage travel mechanism, and boom pitch mechanism. The bridge-type grab ship unloader can run on rails, with the clearance under the gantry high enough for transport vehicles to pass. After grabbing cargo from the ship, the grab bucket unloads the cargo into a conical hopper, which then delivers it to the belt conveyor on the dock through the hopper outlet and then to the storage yard.

[0003] Most of the existing material receiving devices are of this type of conical hopper. Although it can cooperate with ship unloaders and belt conveyors to unload materials, the discharge port position of the conical hopper is fixed to facilitate accurate delivery of materials onto the belt conveyor. As the number of ship unloaders put into operation increases, the conical hopper needs to control its discharge speed to cooperate with the belt conveyor for transport and unloading, so as to avoid the weight of materials discharged by multiple conical hoppers onto the belt being too high, affecting the normal operation of the belt conveyor. However, controlling the discharge speed of the conical hopper will also directly affect the feeding speed of the grab bucket into the conical hopper.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a material receiving device is provided to facilitate the receiving of materials by a bridge grab ship unloader, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a material receiving device for facilitating material receiving by a bridge-type grab ship unloader, so as to solve the above problems.

[0006] The purpose and function of the material receiving device of the utility model, which is convenient for receiving materials by a bridge-type grab ship unloader, are achieved by the following specific technical means:

[0007] A material receiving device for facilitating material receiving by a bridge-type grab ship unloader comprises a conical hopper, a material discharge direction conversion assembly being mounted on the outer wall surface of a discharge end of the conical hopper, two groups of buffer assemblies being symmetrically arranged on the bottom surface of the material discharge direction conversion assembly, a flow guide assembly being mounted between the two groups of buffer assemblies, and a dustproof drive mechanism being mounted on the material discharge direction conversion assembly;

[0008] The material feeding direction conversion component includes a circular block, a conical mounting opening is provided in the middle of the circular block, an annular limiting groove is provided on the top and bottom surfaces of the circular block, a gear ring groove is provided in the middle of the outer wall of the circular block, and a gear ring is fixedly installed in the gear ring groove.

[0009] Furthermore, the blanking direction conversion component also includes an arc-shaped clamping block symmetrically installed on the side wall of the circular block, and an arc-shaped limit block matching the annular limit groove is fixedly installed symmetrically on the rear end of the arc-shaped clamping block.

[0010] Furthermore, each group of the buffer components includes two telescopic rod sleeves fixedly mounted on the bottom surface of the arc-shaped block, a sliding rod is slidably provided in the middle of the telescopic rod sleeve, and a spring is sleeved on the outer wall surface of the sliding rod located in the inner cavity of the telescopic rod sleeve.

[0011] Furthermore, the guide assembly includes a guide trough plate, and mounting blocks are symmetrically fixedly installed in the middle of the left and right side walls of the guide trough plate, and the mounting blocks are fixedly connected to the bottom surface of the lower end of the sliding rod on the same side.

[0012] Furthermore, the bottom surface of the left end of the guide trough plate is higher than the bottom surface of the right end.

[0013] Furthermore, the dustproof drive mechanism includes two arc-shaped dustproof blocks symmetrically installed on the outer wall of the circular block in the front and rear directions. The outer walls at both ends of the arc-shaped dustproof block are respectively fixedly installed on the outer end side walls of the arc-shaped block on the same side, and a gear dust cover is fixedly installed on the outer wall of the front arc-shaped dustproof block, and a gear is rotatably installed in the middle of the gear dust cover.

[0014] Furthermore, a motor is fixedly mounted on the gear dust cover, a rotating end of the motor is fixedly connected to the middle of the top surface of the gear, and the gear is meshed with the ring gear.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The utility model drives the material unloading direction conversion assembly to rotate through the dustproof driving mechanism on the material unloading direction conversion assembly, thereby rotating the buffer assembly installed at the lower end of the material unloading direction conversion assembly and the guide assembly between the two groups of buffer assemblies, thereby making the angle between the guide end of the guide trough plate and the conveying direction of the belt conveyor form 90 degrees. At this time, the material can be transported by a transport vehicle or a new belt conveyor can be set up, avoiding the simultaneous operation of multiple ship unloaders, which would affect the normal operation of the belt conveyor due to the excessive weight of the material on the belt.

[0017] 2. The utility model transports materials in the above-mentioned manner, so there is no need to control the unloading speed of the conical hopper, thereby avoiding affecting the feeding speed of the grab bucket into the conical hopper, thereby improving the working efficiency of the ship unloader and improving the adaptability of the conical hopper.
