Description

Technical Field

[0001] The utility model belongs to the technical field of coal feeders, and specifically refers to a coal spill prevention device for coal feeders. Background Art

[0002] A coal feeder is a mechanical device used to quantitatively supply fuel to equipment such as boilers and coal mills. The size of the discharge port of the coal feeder is fixed. Usually, when coal leaves the outlet of the coal feeder, due to the lack of effective blocking and guiding measures, it is prone to the phenomenon of throwing and scattering, entering the interlayer of the conveyor belt, resulting in damage to equipment components and waste of coal materials, increasing production costs. Content of the Utility Model

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a coal spill prevention device for coal feeders, effectively solving the problem of easy throwing and scattering of coal materials at the discharge port.

A driven plate is slidably arranged at the bottom of the machine shell. The coal bunker is arranged at the top of the machine shell. The discharge port is arranged on the side of the machine shell. Vertical grooves are arranged on the side walls on both sides of the discharge port. A support shaft is rotatably arranged in the grooves. The top end of the support shaft extends out of the top wall of the machine shell. A baffle is fixedly sleeved on the support shaft close to the bottom wall of the discharge port. The bottom wall of the baffle is in close contact with the top wall of the driven plate, blocking the coal materials discharged from the discharge port and avoiding the phenomenon of throwing and scattering.

[0005] Preferably, a worm gear is fixed at the top end of the support shaft. An external connecting top plate is fixed on the outer side wall of the top of the machine shell. A bidirectional worm is rotatably arranged on the external connecting top plate. The bidirectional worm is meshed with the worm gear. A rotating block is fixed at one end of the bidirectional worm. Rotating the rotating block drives the bidirectional worm to rotate. The bidirectional worm drives the worm gear to rotate. The worm gear drives the support shaft and the baffle to rotate, and the baffle blocks the coal materials at the discharge port.

[0006] Preferably, the sleeved part of the baffle and the support shaft is of an arc-shaped structure. A top pressing and limiting plate with a circular arc cross-section is arranged on the inner wall of the groove. The baffle rotates closely against the top pressing and limiting plate, preventing coal materials from entering the gap between the groove and the baffle and affecting normal use.

[0007] Preferably, a driving motor is arranged on the outer side wall at the top of the discharge port. The output end of the driving motor is fixedly connected with a fixed shaft. The end of the fixed shaft away from the driving motor is rotatably arranged on the inner side wall of the discharge port. A connecting frame is fixed on the fixed shaft. An outlet adjusting plate is fixedly connected to the connecting frame. The driving motor drives the fixed shaft and the connecting frame to rotate, and then drives the outlet adjusting plate to rotate, thereby adjusting the size of the discharge port to ensure that the coal materials can be evenly and stably output.

[0008] Preferably, support outer plates are fixed on the outer side walls at both ends of the display stand. A second motor is provided on the support outer plate. A support shaft is fixed on the output end of the second motor. One end of the support shaft away from the second motor is rotatably arranged on the support outer plate. One side of the bottom of the protective cover is fixedly sleeved on the support shaft.

[0009] Preferably, a sloping plate is provided below the coal bunker inside the casing to play a guiding role.

[0010] Preferably, a crank and connecting rod mechanism is fixedly connected to one end of the driven plate.

[0011] The beneficial effects achieved by the present utility model adopting the above structure are as follows:

[0012] 1. By arranging baffles on both sides of the discharge port to block the coal material, it can prevent the coal material from splashing out of control when leaving the discharge port, enabling more coal to be accurately conveyed to the predetermined position, thereby improving the utilization rate of the coal material and reducing the production cost; avoiding the accumulation of scattered coal material around the equipment, reducing the risk of safety accidents such as equipment failures and slips caused by the accumulation of coal material, and contributing to improving the production efficiency.

[0013] 2. By rotating the rotating block to drive the double-headed worm and the worm gear to rotate, the angle of the baffle can be flexibly adjusted, more precisely controlling the flow direction and speed of the coal material, thereby minimizing the phenomenon of coal scattering; adjusting the angle of the baffle can control the distribution of the coal material, making the coal material fall on the conveyor belt more evenly, improving the working efficiency and stability.

A support shaft 6 is rotatably arranged in the embedded grooves 5. The top end of the support shaft 6 extends out of the top wall of the machine shell 1. A baffle plate 7 is fixedly sleeved on the support shaft 6 close to the bottom wall of the discharge port 3. The bottom wall of the baffle plate 7 is in close contact with the top wall of the driven plate 4 to block the coal material discharged at the discharge port 3 and avoid spillage.

[0024] As Figure 2As shown in the figure, a worm gear 11 is fixed to the top end of the support shaft 6. An external connection top plate 13 is fixed to the outer side wall of the top of the machine housing 1. A bidirectional worm 10 is rotatably provided on the external connection top plate 13.

Rotating the rotating block 12 drives the bidirectional worm 10 to rotate. The bidirectional worm 10 drives the worm gear 11 to rotate. The worm gear 11 drives the support shaft 6 and the baffle 7 to rotate. The baffle 7 blocks the coal material at the discharge port 3.

[0025] As Figure 4 shown, the socket joint of the baffle 7 and the support shaft 6 is of an arc-shaped structure. A top-tightening limiting plate 17 with an arc-shaped cross-section is provided on the inner wall of the embedding groove 5.
