BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a schematic structural diagram of a flow guiding device of a transfer machine according to an embodiment of the present invention.

[0018] Reference numerals:

[0019] The first guard plate 1, the main baffle plate 11, the connecting plate 111, the swing baffle plate 12, the second guard plate 2, the guide groove 3, the transfer machine guard plate 4, the guide rod 5, the limit block 51, and the elastic member 6. DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] like Figure 1 As shown, the transfer machine guide device of the embodiment of the present invention includes a transfer machine guard plate 4 and a guide groove 3.

[0022] Specifically, the transfer machine guard plate 4 has a transfer channel, which is connected to the discharge port of the transfer machine. The guide groove 3 includes a first guard plate 1 and a second guard plate 2 which are arranged at intervals and constitute the guide channel. The guide channel is connected to the transfer channel. The first guard plate 1 and / or the second guard plate 2 include a main baffle 11 and a swing baffle 12. The main baffle 11 is fixedly connected to the transfer machine guard plate 4, and the swing baffle 12 is rotatably connected to the main baffle 11 and is located on the side of the main baffle 11 away from the transfer machine guard plate 4.

[0023] like Figure 1As shown, the main baffle 11 is arranged next to the discharge port of the transfer channel, and the tail end is connected to the swing baffle 12. During the coal block conveying process, the coal blocks conveyed out of the transfer channel first pass through the main baffle 11 and then pass through the swing baffle 12. As the coal blocks are conveyed, coal blocks are more likely to accumulate at the tail end of the guide channel. If there are large-volume coal blocks that are difficult to pass through, the swing baffle 12 corresponding to the tail end of the guide channel can be flipped outward under the pressure of the large-volume coal blocks, thereby expanding the diameter of the tail end of the guide channel, so that the large-volume coal blocks can flow smoothly, avoiding block jamming, and improving the operating efficiency of the coal mine excavation and transportation system.

[0024] The transfer machine guide device of the embodiment of the present invention has a transfer machine guard plate 4 with a transfer channel, which is connected to the discharge port of the transfer machine. The guide trough 3 includes a first guard plate 1 and a second guard plate 2 which are arranged at intervals and constitute the guide channel. The guide channel is connected to the transfer channel. The first guard plate 1 and / or the second guard plate 2 include a main baffle 11 and a swing baffle 12. The main baffle 11 is fixedly connected to the transfer machine guard plate 4, and the swing baffle 12 is rotatably connected to the main baffle 11 and is located on the side of the main baffle 11 away from the transfer machine guard plate 4. Therefore, when there are large-volume coal blocks or coal blocks are accumulated at the tail end of the flow channel, the swing baffle 12 can be flipped outward to increase the tail end diameter of the guide trough 3 to allow coal blocks to pass smoothly, avoid block jamming, and improve the operating efficiency of the coal mine excavation and transportation system.

[0025] In addition, in order to improve the convenience of transportation, the conventional guide chute 3 usually increases the size of the inlet end to facilitate the reception of coal blocks discharged from the crusher, and the rear end size of the guide chute 3 will gradually decrease to facilitate transportation. Under this conventional design, large coal blocks usually will not have a blocking problem at the front end of the guide chute 3, and as the guide chute 3 becomes smaller, the large coal blocks may not be discharged from the tail end. The present application sets the swing baffle 12 at the tail end according to actual needs, which can solve this problem, and only minor changes are made to the guide chute 3.

[0026] Furthermore, the guide device of the transfer machine further includes a reset member, one end of which is connected to the main baffle 11, and the other end is connected to the swing baffle 12, and the reset member has a force to drive the swing baffle 12 to reset. Therefore, when a large-volume coal block passes through, the reset member can drive the swing baffle 12 to reset, thereby allowing the guide trough 3 to maintain a normal guide function and shape in a normal state (when no large-volume coal blocks pass through).

[0027] Specifically, Figure 1As shown, the reset member includes a guide rod 5 and an elastic member 6. The guide rod 5 extends along the length direction of the guide channel. A stop block 51 is provided on the guide rod 5. A connecting plate 111 is provided on the main baffle 11. One end of the guide rod 5 can movably pass through the connecting plate 111, and the other end is connected to the swing baffle 12. The elastic member 6 is arranged between the connecting plate 111 and the stop block 51. Therefore, when the swing baffle 12 is turned outward, the swing baffle 12 can push the guide rod 5 backward, and the stop block 51 moves accordingly and cooperates with the connecting plate 111 to compress the elastic member 6. After the large-volume coal block passes, the elastic member 6 rebounds and pushes the guide rod 5 to reset, and the guide rod 5 pushes the swing baffle 12 to rotate inward to the initial position.

[0028] Furthermore, a fixing block connected to the guide rod 5 is provided on the swing baffle 12, the fixing block has a fixing point connected to the guide rod 5, and a guide hole for the guide rod 5 to pass through is provided on the connecting plate 111. When the swing baffle 12 does not deflect, there is an angle between the connecting line between the guide hole and the fixing point and the swing baffle 12. In other words, the moving path of the guide rod 5 is inclined, and the backward thrust of the swing baffle 12 when rotating is also inclined, so that the force of the swing baffle 12 pushing the guide rod 5 backward is consistent with the moving track direction of the guide rod 5, which can avoid jamming and ensure the smoothness of opening and resetting of the swing baffle 12.

[0029] Furthermore, when the swing baffle 12 does not deflect, the angle between the extension direction of the swing baffle 12 and the extension direction of the guide rod 5 is equal to the angle between the extension direction of the main baffle 11 and the extension direction of the guide rod 5. Therefore, in the reset state, after the guide rod 5 pushes the swing baffle 12 to the end of the rotation, the swing baffle 12 and the main baffle 11 are just smoothly connected, and there is no angle or bend at the connection, which is conducive to the transportation of coal blocks.

[0030] In some embodiments, the elastic member 6 is a return spring, and the return spring is sleeved on the guide rod 5. On the one hand, the spring itself has stable performance and can be used for a long time. On the other hand, sleeved on the guide rod 5, the spring can avoid deviation during repeated expansion and contraction of the spring, thereby ensuring the stability of the reciprocating motion of the guide rod 5.

[0031] Furthermore, a limiting protrusion is provided at the end of the guide rod 5 passing through the connecting plate 111. It can be understood that the setting of the limiting protrusion can play an anti-slip effect.

[0032] In some embodiments, the dimension of the guide groove 3 in the spacing direction between the first guard plate 1 and the second guard plate 2 gradually decreases in the direction away from the transfer channel. In other words, the front opening of the guide groove 3 is larger, and the rear opening is smaller. The larger opening is convenient for receiving coal blocks, and the subsequent gradually smaller design facilitates the gathering and transportation of coal blocks.

[0033] In some embodiments, the main baffle 11 and the swing baffle 12 are connected by hinges, which have great connection reliability and rotation range. Optionally, other connecting members other than hinges can be used between the main baffle 11 and the swing baffle 12, which will not be repeated here.
