Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mining equipment, and particularly relates to a mine machinery material uniformizing mechanism. BACKGROUND

[0002] The material uniformizing mechanism in mine machinery is a device specially designed to ensure that the material is evenly distributed during conveying or processing. It is usually installed at the front end or material inlet of mechanical equipment such as crushers, screening equipment or conveyor belts to ensure that the material flow entering the next process has stable and uniform characteristics. The material uniformizing mechanism is crucial to maintaining the efficient operation of the entire production system, as it helps to reduce machine wear, prevent overload and improve the quality consistency of the final product. By precisely controlling the flow and distribution of the material, the material uniformizing mechanism provides ideal working conditions for subsequent processing processes.

[0003] The utility model with publication number CN 216174180 U discloses a material uniformizing mechanism for mine machinery equipment, which aims to achieve the reciprocating motion of multiple material uniformizing plates through the coordinated work of the driving motor and the rotating shaft. The driving motor drives the rotating shaft to rotate, and the multiple material uniformizing plates installed on the rotating shaft move regularly forward and backward to ensure that the material is evenly distributed and improve production efficiency and quality. However, since the rotating shaft used in the material uniformizing mechanism is relatively long, the output shaft of the driving motor not only needs to bear a large torque but also is affected by a deflection torque during actual operation. This deflection torque is caused by the relatively long length of the rotating shaft and its asymmetric load. The deflection torque can cause the output shaft to bend and deform, further increasing the mechanical stress of the motor shaft and bearings. In this case of high torque plus deflection torque, the working conditions of the driving motor output shaft and its supporting bearings become more demanding. Working in such an environment for a long time can cause various problems, including but not limited to bearing damage, shaft bending or breaking, etc. Therefore, it is necessary to improve.

[0004] The technical problem to be solved by the utility model is to provide a mine machinery material uniformizing mechanism.

[0005] To solve the above technical problems, the technical scheme of the utility model is as follows:

[0006] The invention discloses a kind of mine machinery uniform mechanism, including base, box body with base hinged at right end, multiple uniform plates slidingly disposed on the box body, adjusting mechanism for adjusting the inclination angle of box body disposed on base, multiple guide plates disposed on the box body, and drive assembly for driving the reciprocating movement of uniform plate;The left end of the uniform plate is fixedly connected with a connecting plate, a drive plate is fixedly connected on the connecting plate, and the drive plate is provided with a U-shaped recess;Two sides of the drive plate are fixedly connected with mounting plate on the box body, the crankshaft is rotatably installed on the mounting plate, and the middle part of the crankshaft is embedded in the U-shaped recess;The drive assembly includes support plate fixedly connected to the box body, and speed reducer motor fixedly connected to the support plate;The output end of the speed reducer motor is coaxially fixedly connected with one end of the crankshaft.

[0008] Preferably, the upper end of the support frame is provided with a buffer layer.

[0009] Preferably, the crankshaft includes a middle section, end sections coaxially located at both ends of the middle section, and the end sections are not coaxial with the middle section;The diameter of the middle section is equal to the width of the U-shaped recess.

[0010] Preferably, the sliding arrangement of the uniform plate and the box body is that a guide rod with a guide groove is fixedly connected to the box body, a guide block is fixedly connected to the uniform plate, and the guide block is slidingly embedded in the guide groove.

[0011] Preferably, a fixed shaft is fixedly connected to the left end of the box body, a vertical rod is fixedly connected to the base, and the fixed shaft is rotatably installed on the vertical rod.

[0012] The above technical solution has the following advantages:

[0013] In the utility model, the output end of the speed reducer motor is significantly optimized, so that it mainly bears torque and hardly bears any deflection torque. The improvement in design effectively avoids the common problem in traditional design, i.e. additional mechanical stress and wear caused by deflection torque. By ensuring that the output end of the speed reducer motor only focuses on transmitting the torque required for rotary motion and does not have to cope with the deflection torque that may cause shaft bending or misalignment, the working burden of the speed reducer motor and its supporting bearings is greatly reduced. Therefore, the speed reducer motor can operate more stably and efficiently under the optimized design condition, and its service life is significantly prolonged. At the same time, due to the reduction of wear and potential failure caused by deflection torque, the maintenance requirement is also greatly reduced, thereby reducing the long-term operating cost. Such design not only improves the reliability of the system, but also brings lower maintenance cost and higher economic benefit to the user. BRIEF DESCRIPTION OF DRAWINGS

[0029] As a preferred technical solution of the present embodiment, the adjusting mechanism 4 comprises a hydraulic cylinder 14 fixedly connected to the base 1, a rail 15 fixedly connected to the base 1, and a supporting frame 16 slidingly installed on the rail 15; the hydraulic cylinder 14 has a piston rod 17, the upper end of the piston rod 17 abuts against the bottom of the box 2; the lower end of the supporting frame 16 is provided with a guide slot 18, the rail 15 penetrates through the guide slot 18, and the lower part of the supporting frame 16 is screwed with a locking bolt 19 penetrating into the guide slot 18.

[0030] When the angle of the box 2 needs to be adjusted, loosen the locking bolt 19, move the support frame 16 to the right, then drive the box 2 to rotate through the hydraulic cylinder 14 to realize angle adjustment, after the angle adjustment is completed, move the support frame 16 to make its upper end abut against the box 2, and then tighten the locking bolt 19. Obviously, other existing adjustment mechanisms can also be used.

[0031] As a further improved technical solution of the embodiment, the upper end of the support frame 16 is provided with a buffer layer (not shown in the figure), which provides reliability of support and avoids wear and noise caused by hard friction.

[0032] As a specific technical solution of the embodiment, the crankshaft 11 includes a middle section 20 and coaxial end sections 21 located at both ends of the middle section 20; the end sections 21 are different in axis from the middle section 20; the diameter of the middle section 20 is equal to the width of the U-shaped groove 8. The depth of the U-shaped groove 8 can meet the space requirement of the rotation of the crankshaft 11, and the crankshaft 11 can push the driving part 9 to move back and forth after rotation.
