Description

Technical Field

[0001] The utility model belongs to the technical field of underground mining, and in particular relates to a flow guide device for a transfer machine. Background Art

[0002] The transfer machine is suitable for mechanized tunneling operations in mines. As a supporting equipment for the working face scraper, one end is connected to the scraper and the other end is connected to a belt conveyor or a mine car. It is a relay transfer equipment that can ensure the continuity of transportation and transfer, shorten auxiliary working hours, and improve work efficiency. The steeply inclined thin coal seam coal mining working face has a large working face angle and a high unloading drop between the transfer machine and the scraper. When the working face scraper is unloading, the coal gangue rolls down quickly and is difficult to control, which easily causes material accumulation at the transfer machine. Therefore, when the coal flow is broken by the crusher, due to the small cross-section at the crusher hammer head, the crushing of coal blocks will increase the running resistance of the transfer machine, which is easy to cause damage to the chain of the transfer machine or burn out the motor. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a flow guide device for a transfer machine, which can make the accumulated coal flow pass through the crusher more evenly and reduce the running resistance of the coal flow at the crusher.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A guide device for a transfer machine includes a connecting plate and a guide plate vertically installed on the connecting plate, wherein the connecting plate is installed on the upper side of a middle groove of the transfer machine, the guide plate is connected to the lower side of the connecting plate and extends into the middle groove, and a gap exists between the lower edge of the guide plate and the bottom of the middle groove.

[0006] Furthermore, the guide plate is a bent plate with left and right sides bent toward the downstream of the coal flow direction.

[0007] Furthermore, a plurality of guide plates are provided, and the lateral lengths and vertical lengths of the plurality of guide plates are inconsistent.

[0008] Furthermore, a plurality of guide plates are arranged in sequence along the coal flow direction.

[0009] Furthermore, the transverse lengths of the plurality of guide plates gradually increase along the coal flow direction.

[0010] Furthermore, the vertical lengths of the plurality of guide plates gradually decrease along the coal flow direction.

[0011] Furthermore, reinforcing ribs are welded on the back side of the guide plate.

[0012] Furthermore, the connecting plate and the guide plate are welded as one body.

[0013] Furthermore, both sides of the connecting plate are detachably mounted on the upper ends of the coal walls on both sides of the middle groove through connecting pieces.

[0014] Furthermore, an adjusting gasket is detachably installed between the connecting plate and the coal wall.

[0015] After adopting the above technical solution, the beneficial effects of the utility model are:

[0016] Since the guide device for the transfer machine of the utility model includes a connecting plate and a guide plate vertically installed on the connecting plate, the connecting plate is installed on the upper side of the middle groove of the transfer machine, the guide plate is connected to the lower side of the connecting plate and extends into the middle groove, and there is a gap between the lower edge of the guide plate and the bottom of the middle groove. When the accumulated coal blocks pass through, the guide plate pushes the coal flow more evenly and then passes through the crusher, avoiding excessive resistance when the coal flow passes through the crusher, causing overload of the transfer machine, and reducing the occurrence of malfunctions.

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

[0021] like Figure 1 As shown, a guide device for a transfer machine includes a connecting plate 11 and a guide plate 12 vertically mounted on the connecting plate 11. The connecting plate 11 is mounted on the upper side of the middle groove 2 of the transfer machine, and the guide plate 12 is connected to the lower side of the connecting plate 11 and extends into the middle groove 2. There is a gap between the lower edge of the guide plate 12 and the bottom of the middle groove 2. When the accumulated coal blocks pass through, the guide plate 12 pushes the coal flow more evenly and then passes through the crusher. The height of the coal blocks piled up at the gap is significantly reduced, thereby avoiding the situation where the coal flow is too large when passing through the crusher, causing the transfer machine to be overloaded, and reducing the occurrence of failures.

[0022] like Figure 2As shown, the guide plate 12 is a bent plate that is bent on both sides toward the downstream of the coal flow direction. The coal blocks are accumulated in the middle position of the middle groove 2. The coal flow passing through the guide plate 12 will spread to both sides, which is convenient for lowering the height of the accumulation position and reducing the force on the end face of the guide plate 12.

[0023] like Figure 1 and Figure 2 As shown in the figure, a plurality of guide plates 12 are provided, and the transverse lengths and vertical lengths of the plurality of guide plates 12 are inconsistent, so as to facilitate spreading the coal flow on both sides of the guide plates 12. Specifically, the plurality of guide plates 12 are arranged in sequence along the direction of the coal flow, wherein the transverse lengths of the plurality of guide plates 12 gradually increase along the direction of the coal flow, and the vertical lengths of the plurality of guide plates 12 gradually decrease along the direction of the coal flow, so that the coal flow can be spread more evenly after multiple guides. The coal flow direction is specifically shown by the arrow in the figure.

[0024] like Figure 2 As shown, a reinforcing rib 13 is welded on the back of the guide plate 12 to enhance the strength of the guide plate 12 and prevent the guide plate 12 from being excessively bent, thereby affecting the guide effect.

[0025] like Figure 1 As shown, the connecting plate 11 and the guide plate 12 are welded as one. The two sides of the connecting plate 11 are detachably mounted on the upper ends of the coal walls 3 on both sides of the middle trough 2 through connecting pieces, and an adjusting gasket 14 is detachably mounted between the connecting plate 11 and the coal wall 3. By adjusting the specifications and quantity of the installed adjusting gaskets 14, the height of the gap between the guide plate 12 and the bottom of the middle trough 2 can be adjusted so that the height of the coal block accumulation meets the needs of the crusher.

[0026] The utility model provides a guide device for a transfer machine by setting a connecting plate on the upper side of the middle groove of the transfer machine, and the lower side of the connecting plate is connected to a guide plate extending into the middle groove, and a gap is provided between the lower edge of the guide plate and the bottom of the middle groove. When the accumulated coal blocks pass through, the guide plate pushes the coal flow more evenly and then passes through the crusher, thereby avoiding excessive resistance when the coal flow passes through the crusher, causing overload of the transfer machine, and reducing the occurrence of malfunctions.
