DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. The parts that are not described and disclosed in detail in the following embodiments of the present invention should be understood as existing technologies known or should be known to those skilled in the art, such as the structure, model and specific working principle of the transfer machine.

[0022] Example 1

[0023] An extension device for a transfer machine, such as Figure 1-4 As shown, it includes a plurality of chutes that can be spliced. The chute includes a rectangular conveying plate 1 and a support plate 2, and the conveying plate 1 is located above the support plate 2. The conveying plate 1 is provided with baffle plates 3 on both sides along its length direction. The baffle plates 3 and the conveying plate 1 form a channel 4 for raw coal to pass through. When the two chutes are spliced, if the splicing is uneven, it will affect the efficiency of the transfer machine in conveying raw coal and even damage the scraper of the transfer machine. Therefore, both ends of the baffle plate 3 are respectively provided with an insertion block 8 and an insertion strip 9. The insertion block 8 is provided with a slot 13 for the insertion strips 9 on other baffle plates 3 to enter. The insertion block 8 is also provided with a positioning screw 10 for controlling the height of the insertion strip 9 in the slot 13. The conveying plate 1 and the support plate 2 are connected by a connecting plate 5, and the conveying plate 1, the support plate 2 and the support plate 3 are connected by a connecting plate 5. The plate 2 and the connecting plate 5 enclose a space 6 for the scraper of the transfer machine to pass through. When the two chutes are spliced, the insert 9 on one baffle plate 3 is inserted into the slot 13 of the insert block 8 on the other baffle plate 3, and then the positioning screw 10 is turned to change the height of the insert 9 in the slot 13 by changing the height of the positioning screw 10 entering the slot 13 until the heights of the two chutes are flush. Then, in order to ensure the stability of the connection between the two chutes, two protrusions 12 are provided on the connecting plate 5, and the protrusions 12 on the connecting plates 5 of the two chutes can be connected by a fixing ring 11. There will be a certain gap between the two protrusions 12, or if they cannot be completely fitted with the fixing ring 11, a wedge block can be placed in the non-fitting place to clamp it. In order to realize the connection between the chute and the transfer machine, at least one fixed plate 7 is connected to the baffle plate 3 and the connecting plate 5 close to the transfer machine. The fixed plate 7 is used to connect with the transfer machine. The fixed plate 7 and the transfer machine are connected by multiple bolts. Multiple corresponding screw holes 701 are opened on the fixed plate 7. According to actual conditions, an appropriate number of chutes are spliced.
