Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for bucket wheel excavators, and in particular to an anti-collision material guiding device for bucket wheel excavators. Background Technology

[0002] The bucket wheel primarily lifts coal ore into the slewing support structure, which then transports the coal ore to the discharge point. Therefore, a guide plate is installed between the bucket wheel and the slewing support structure. The guide plate's function is to prevent the material from flying out of the bucket wheel after detaching from it. Consequently, the guide plate is subjected to repeated impacts from coal blocks, causing severe deformation or even cracking of the arc-shaped guide plate, which seriously affects the safety of the bucket wheel's operation and the stability of the equipment.

[0003] Publication number CN214568396U discloses an anti-collision material guiding device for a bucket wheel excavator, including a support plate, a motor, a connector, a rotating shaft, a hopper, and a bracket. The motor is mounted on the upper surface of the support plate; the connector is connected to the motor; the connector is connected to the rotating shaft; the outer wall of the hopper is fixedly connected to the rotating shaft; and the bracket is mounted on the outer wall of the hopper. This invention sets the guide plate in the form of a hopper. During material feeding, the motor drives the hopper to rotate clockwise or counterclockwise. When material (coal lumps) enters the hopper, the rotation of the hopper reduces the impact force of the coal lumps on the inner wall of the hopper, preventing the hopper structure from being deformed or cracked by repeated impacts from coal lumps, thus protecting the safety of the bucket wheel excavator's operation and the stability of the equipment.

[0004] While the above-mentioned solution can reduce the impact force of coal on the inner wall of the bucket wheel, the rotation process of the bucket wheel requires gear transmission components, which are complex in structure and difficult to maintain. In addition, the fixed position of the bucket wheel on the drive component restricts the space of other components and makes maintenance difficult. Therefore, we propose an anti-collision guiding device for bucket wheel excavators. Utility Model Content

[0005] The main purpose of this utility model is to provide a bucket wheel excavator anti-collision material guiding device. By setting an adjustment unit and a positioning unit, it solves the problems that the rotation process of the bucket requires gear transmission components, which are complex in structure and troublesome to maintain. In addition, the fixed position of the bucket on the drive component leads to limited space for other components and difficult maintenance.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a bucket wheel excavator anti-collision guiding device, including a carrier plate and a hopper and guiding components located above the carrier plate, and further including: an adjustment unit and a positioning unit disposed between the carrier plate and the hopper;

[0007] The adjustment unit includes a servo motor, a support cylinder, a leveling plate, and a connecting column. The servo motor is embedded in the center of the top surface of the carrier plate. The support cylinder is fixedly installed at the output end of the servo motor, and the top surface of the support cylinder has a cross-shaped connecting groove. The leveling plate is fixedly installed at the center of the bottom slope of the hopper, and the bottom surface of the leveling plate is parallel to the top surface of the carrier plate. One end of the connecting column is connected to the center of the bottom surface of the leveling plate, and the other end of the connecting column extends movably into the connecting groove, and the end face of the connecting column is cross-shaped.

[0008] The positioning unit includes a transverse sleeve, a support plate, and a positioning screw. The transverse sleeve is fixedly disposed on the outer circumferential surface of the middle end of the support cylinder. The support plate is fixedly disposed on the bottom surface of one side of the leveling plate. The positioning screw is threaded onto the bottom surface of one side of the support plate and extends movably into the transverse sleeve. There are two transverse sleeves in total, which are symmetrically distributed on the outer circumferential surface of the support cylinder. The support plate and the positioning screw are configured in a one-to-one correspondence with the transverse sleeves.

[0009] Preferably, the servo motor, the supporting cylinder, and the connecting column are all located on the same vertical central axis.

[0010] Preferably, the support plate and the transverse sleeve are arranged perpendicular to each other.

[0011] Preferably, the positioning screw and the assembly post are arranged perpendicular to each other.

[0012] Preferably, the guiding assembly includes brackets and rollers. Two brackets are symmetrically fixed on the top surface of the carrier plate, and two rollers are respectively fixed on the top of the two brackets. The bottom surface of the hopper has two arc-shaped grooves whose positions and sizes match the positions and sizes of the two rollers.

[0014] Preferably, a fixed support is fixedly provided at the corner of the bottom surface of the carrier plate, and the fixed support is provided with mounting holes.

[0015] Compared with the prior art, the present invention provides an anti-collision material guiding device for bucket wheel excavators, which has the following advantages:

[0016] 1. In this utility model, by setting an adjustment unit, before the hopper receives auxiliary support from the guiding component above the carrier plate, the assembly column fixed at the center of the bottom slope of the hopper by the finding plate can be inserted into the support cylinder installed on the output end of the servo motor. The cross-shaped assembly groove opened on the top surface of the support cylinder can cooperate with the support cylinder and the cross-shaped assembly column on the end face to maintain a uniform placement angle. The operation of the servo motor can drive the assembly column to rotate in a certain range of forward and reverse directions through the support cylinder. The hopper rotates accordingly to reduce the impact force of the coal block. The equipment rotates with the hopper, which is simple and flexible in structure and easy to disassemble and maintain.

[0017] 2. In this utility model, by setting a positioning unit, after the assembly column is assembled into the support cylinder, the support plate on the bottom surface of the flat plate can reach the outer side of the end of the transverse sleeve. After rotating the positioning screw so that its thread is assembled into the side of the bottom end of the support plate, the positioning screw fixed to the support plate can be inserted into the transverse sleeve. The hopper is further locked and supported on the assembly column. After removing the positioning screw, the hopper can be removed from the support cylinder. The equipment limits the hopper stably and flexibly. Attached Figure Description
