[0016] Figure 2 is Figure 1 a side sectional view of the accommodating housing in

[0017] Figure 3 is Figure 1 a front sectional view of the accommodating housing in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be clearly and completely described below with reference to the drawings and embodiments:

[0019] As Figures 1 to 3As shown in the figure, a coal pusher for coal bunker discharging of the present utility model includes a receiving housing 1. A support portion 2 is movably arranged inside the receiving housing 1. The support portion 2 can be set as a plate-like structure, a rod-like structure or a structure combining a plate and a rod according to requirements. A plurality of pushing plates 3 are arranged at intervals along the height direction on both sides of the support portion 2. The pushing plates 3 on both sides of the support portion 2 are symmetrically arranged. Adjusting grooves 4 are formed on both sides of the receiving housing 1. One end of the pushing plate 3 away from the support portion 2 passes through the adjusting groove 4. The height of the adjusting groove 4 is the stroke for the up and down movement of the pushing plate 3. The top end of the support portion 2 movably passes through the top of the receiving housing 1 and is connected to a driving member. The driving member is used to control the up and down movement of the support portion 2. During operation, under the drive of the driving member, the support portion 2 drives the pushing plates 3 to move up and down, thereby increasing the disturbance of the coal material, preventing the coal material from accumulating and blocking in the coal bunker, and ensuring the smooth falling of the coal material. It only needs to control the driving member to be turned on regularly, without the need to stop the machine or manual intervention throughout the process. The operation and use are convenient, which can effectively improve the work efficiency and has strong practicability.

[0020] Further, in this embodiment, the driving member preferably adopts a hydraulic cylinder 5. A connecting plate 6 is arranged at the telescopic end of the hydraulic cylinder 5. The connecting plate 6 is connected to the top of the support portion 2. During installation, the hydraulic cylinder 5 is installed outside the coal bunker, and the receiving housing 1 is installed on the inner wall of the coal bunker. With the expansion and contraction of the hydraulic cylinder 5, the up and down movement of the pushing plate 3 is realized, thereby increasing the disturbance of the coal material and preventing the coal material from being blocked. Among them, the end of the pushing plate 3 located outside the receiving housing 1 is an arc-shaped structure extending towards the middle of the coal bunker. To increase the contact area between the pushing plate 3 and the coal material and increase the disturbance range of the coal material, further reducing the probability of coal bunker blockage. In addition, a plurality of disturbing rods 7 are arranged on the inner side wall of the pushing plate 3, which can further increase the disturbance range of the coal material. Among them, the disturbing rods 7 are preferably set as circular structures with tips to reduce the resistance when the pushing plate 3 moves up and down.

[0021] Further, on one side of the receiving housing 1 adjacent to the pushing plate 3, a hinged groove is formed in the vertical direction. A push rod 9 is hinged in the hinged groove. The push rod 9 is connected to the support portion 2 through a connecting member. During operation, as the support portion 2 moves up and down, the push rod 9 swings up and down along the hinge point. The push rod 9 can provide supplementation for the blind area that cannot be covered between the two pushing plates 3, further increasing the disturbance range of the coal material and ensuring the smooth falling of the coal material.

[0022] Among them, in this embodiment, the connecting member is a hinged rod 8. One end of the hinged rod 8 is hinged to the support portion 2, and the other end is hinged to the push rod 9. Among them, the push rod 9 is an L-shaped structure. In the initial state, the push rod 9 is in a state parallel to the support portion 2 to reduce the resistance of the coal material entering the coal bunker. Preferably, a groove 10 is arranged on the receiving housing 1. The groove 10 can receive and accommodate the push rod 9.

[0023] When the utility model is in use, first install the accommodating shell 1 on the inner wall of the coal bunker. One end of the supporting part 2 extends out from one side of the top of the coal bunker in a movable manner and is connected to the hydraulic cylinder 5 arranged on the outer wall of the coal bunker through the connecting plate 6. During operation, regularly start the hydraulic cylinder 5 to drive the supporting part 2 and the push plate 3 to move up and down. At this time, the push rod 9 will also swing synchronously along the hinge point, increasing the disturbance of the coal material in the coal bunker, making the coal material loose, avoiding the accumulation and blockage of the coal material in the coal bunker, and ensuring the smooth falling of the coal material. The structure is simple, the operation and use are convenient, and the practicability is strong. At the same time, in this application, the supporting part 2, the accommodating shell 1, the push plate 3 and the push rod 9 can all be processed and manufactured with steel materials that are easy to obtain, with low cost and easy maintenance.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
