[0040] The present application will be described in further detail below through specific embodiments and in conjunction with the drawings.

[0041] Reference is made to Figure 1 , Figure 2 , Figure 3 andFigure 4 As shown in the figure, the oilfield belt conveyor direct drive motor provided in the embodiment comprises a motor base 100, a motor shell 200, an inner stator 300, an outer rotor 400 and a centering seat 500. The motor shell 200 is arranged on the motor base 100, and the motor base 100 is provided with a mounting hole. The centering seat 500 is detachably arranged at the mounting hole, and the centering seat 500 is provided with a sealing seat 510 for mounting a belt conveyor rotating shaft 600. The centering seat 500 is provided with a positioning ring 520 which can be matched with the oilfield belt conveyor. The inner stator 300 is arranged on the motor base 100, and the motor base 100 is provided with a rotor mounting seat 700. The outer rotor 400 is arranged on the rotor mounting seat 700, and the belt conveyor rotating shaft 600 is inserted into the rotor mounting seat 700.

[0042] Specifically, during the installation of the oilfield belt conveyor direct drive motor, the worker inserts the belt conveyor rotating shaft 600 into the inside of the motor base 100 and the motor shell 200 from the sealing seat 510. The belt conveyor rotating shaft 600 can be inserted into the rotor mounting seat 700. During this process, the centering seat 500 arranged on the motor base 100 can be docked with the positioning structure of the oilfield belt conveyor, thereby completing the centering work of the belt conveyor rotating shaft 600 without the need for centering debugging. Then, the rotation of the outer rotor 400 can drive the belt conveyor rotating shaft 600 to rotate. In addition, the oilfield belt conveyor direct drive motor is directly installed on the oilfield belt conveyor without other transmission structures, which is convenient for the worker to install.

[0043] Among them, the centering seat 500 can be matched with the centering structure of the oilfield belt conveyor, so that the sealing seat 510 arranged in the centering seat 500 is centered with the belt conveyor rotating shaft 600. The inner stator 300 and the outer rotor 400 are both based on the mounting hole of the mounting centering seat 500, so that the axis of the rotor mounting seat 700 connected with the outer rotor 400 coincides with the axis of the belt conveyor rotating shaft 600.

[0044] Among them, the motor base 100 is provided with the motor shell 200, and the motor shell 200 adopts an integrated electromagnetic sound insulation cover. Through such a design, the high-frequency electromagnetic noise radiated by the motor through the shell can be reduced to the greatest extent.

[0045] In addition, the oilfield belt conveyor direct drive motor provided in the embodiment adopts the outer rotor 400 structure, which can improve the peak torque of the motor.

[0046] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, in the optional solution of the embodiment, a stator mounting seat 110 is fixedly arranged on the motor base 100, and the inner stator 300 is arranged on the stator mounting seat 110.

[0047] The stator mounting base 110 is provided with multiple heat dissipation channels 111, and the extension direction of the heat dissipation channels 111 is consistent with the axial direction of the belt conveyor shaft 600.

[0048] Multiple heat dissipation channels 111 are evenly distributed along the circumference of the stator mounting base 110.

[0049] The heat dissipation channel 111 has a waist-shaped groove in cross-section.

[0050] Specifically, when the heat dissipation fan plate 720 on the rotor connecting plate 710 rotates, it can promote airflow, and the air flowing through the heat dissipation channel 111 can cool the inner stator 300.

[0051] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in an optional embodiment, the rotor mounting base 700 has a rotor connecting plate 710, and the outer rotor 400 is mounted on the edge of the rotor connecting plate 710.

[0052] The stator mounting base 110 is detachably provided with a positioning connector 112, and the stator mounting base 110 is connected to the rotor connecting plate 710 through the positioning connector 112; the positioning connector 112 is removed after the belt conveyor shaft 600 is connected to the rotor mounting base 700.

[0053] Specifically, the outer rotor 400 is connected to the rotor mounting base 700 via the rotor connecting plate 710. When the direct drive motor for the oilfield conveyor provided in this embodiment is not installed on the oilfield conveyor, the stator mounting base 110 is connected to the rotor connecting plate 710 via the positioning connector 112, thereby ensuring the stability of the outer rotor 400 and the rotor mounting base 700. When the direct drive motor for the oilfield conveyor provided in this embodiment is installed on the oilfield conveyor, the operator removes the positioning connector 112, thereby enabling the outer rotor 400 to drive the rotor connecting plate 710 and the rotor mounting base 700 to rotate.

[0054] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in an optional embodiment, a heat dissipation plate 720 is provided on the rotor connecting plate 710, and the heat dissipation plate 720 can rotate synchronously with the rotor connecting plate 710.

[0055] Specifically, when the outer rotor 400 rotates, it can drive the rotor connecting plate 710 to rotate. The rotation of the rotor connecting plate 710 can drive the heat dissipation plate 720 to rotate. The rotation of the heat dissipation plate 720 can dissipate heat and cool the inner stator 300 and the outer rotor 400.

[0056] The embodiment provides an oilfield belt conveyor, comprising an oilfield belt conveyor direct drive motor.

[0057] Specifically, the oilfield belt conveyor provided by the embodiment has the advantages of the oilfield belt conveyor direct drive motor compared with the prior art, and details are not repeated here.

[0058] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the present application embodiment.
