[0027] like Figure 1-2 As shown, this embodiment provides a surface feeder track, including a tail drive device 1, a head drive device 2 and a feeding rotary device 3 used in combination, the feeding rotary device 3 includes a rotary chain 301, the tail drive device 1, the head drive device 2, and the rotary chain 301 constitute a set of rotary drive mechanisms for feeding, and the surface feeder track also includes a chain support frame 6 for supporting and guiding the rotary chain 301, the chain support frame 6 is in the shape of a long strip and is arranged on the inner side of the rotary chain 301, the chain support frame 6 lifts and guides the rotary chain 301 on the inner side of the rotary chain 301, the position of the tail drive device 1 is the feeding position of the track, and generally, the material is transported to one side of the tail drive device 1 by a material transport vehicle 100 and then unloaded onto the track;

[0028] like Figure 2-3 As shown, the end of the chain support frame 6 close to the tail drive device 1 is provided with a first threaded hole 601, a second threaded hole 602, a third threaded hole 603 and a fourth threaded hole 604 in a row, which are close to the tail drive device 1 in sequence, and the end of the chain support frame 6 is also installed with a movable support plate 7 by bolts, and the length directions of the two are consistent;

[0029] like Figure 4 As shown, the movable support plate 7 is provided with a first waist-shaped hole 701 and a second waist-shaped hole 702 which are sequentially close to the tail drive device 1 in a row along its length direction, the end of the first waist-shaped hole 701 away from the tail drive device 1 is a first end, and the other end is a second end, the distance between the first end and the second end is equal to the distance between the first threaded hole 601 and the second threaded hole 602, the end of the second waist-shaped hole 702 away from the tail drive device 1 is a third end, and the other end is a fourth end;

[0030] like Figure 5As shown, when the second end is aligned with the first threaded hole 601, the third end is aligned with the third threaded hole 603. At this time, two bolts can be prepared to be screwed into the first threaded hole 601 and the third threaded hole 603 respectively, and the movable support plate 7 is fixed to the chain support frame 6 with the help of the two bolts. At this time, the tendency of the movable support plate 7 to move to the left (i.e., away from the tail drive device 1) is limited by the bolt screwed into the first threaded hole 601, and the tendency of the movable support plate 7 to move to the right (i.e., close to the tail drive device 1) is limited by the bolt screwed into the third threaded hole 603. Therefore, under the joint action of the two bolts, in addition to being tightened and fixed by the bolts, the tendency of the movable support plate 7 to move horizontally is also firmly limited by the two bolts, and the positioning stability is extremely strong. At this time, the movable support plate 7 retracts to the maximum displacement. At this time, the distance between the movable support plate 7 and the tail drive device 1 is the largest, which is conducive to the disassembly, assembly, maintenance, lubrication and other operations of the tail drive device 1.

[0031] like Figure 6 As shown, when the first end head and the second end head are respectively aligned with the first threaded hole 601 and the second threaded hole 602, the third end head is aligned with the fourth threaded hole 604. At this time, two bolts can be prepared to be screwed into the second threaded hole 602 and the fourth threaded hole 604 respectively, and the movable support plate 7 is fixed to the chain support frame 6 with the help of these two bolts. At this time, the tendency of the movable support plate 7 to move to the left (i.e., away from the tail drive device 1) is limited by the bolt screwed into the second threaded hole 602, and the tendency of the movable support plate 7 to move to the right (i.e., close to the tail drive device 1) is limited by the bolt screwed into the fourth threaded hole 604. Similarly, the movable support plate 7 is firmly fixed on the chain support frame 6. At this time, the movable support plate 7 is extended to the maximum displacement. At this time, the distance between the movable support plate 7 and the tail drive device 1 is the smallest, which can maximize the response to the sinking of the slewing chain 301 and realize the lifting of the slewing chain 301.

[0032] Of course, the movable support plate 7 can be freely extended and retracted steplessly to accurately support the different sinking positions of the rotating chain 301. In this embodiment, the movable support plate 7 is detachably installed at the end of the chain support frame 6 by bolts, wherein a plurality of threaded holes are opened on the chain support frame 6, and a plurality of waist-shaped holes are opened on the movable support plate 7, and the waist-shaped holes correspond to the plurality of threaded holes. The position of the movable support plate 7 can be adjusted along the length direction and the bolts can be threaded through the waist-shaped holes and the threaded holes at the same time and tightened, so as to realize the free extension and retraction adjustment and positioning of the movable support plate 7 at the end of the chain support frame 6, so as to accurately cope with different degrees of sinking of the rotating chain 301.

[0033] In some embodiments, Figure 1 As shown, the surface feeder track includes a blocking mechanism 4, which is arranged around the feeding rotary device 3 to prevent material from leaking sideways.

[0034] In some embodiments, Figure 1 As shown, it includes a rainproof canopy 5, which covers the feeding end of the feeding rotary device 3. On the one hand, it can reduce unloading dust, and on the other hand, it can provide a shelter for operators.

[0035] In some embodiments, a groove is provided on one side of the movable support plate 7 close to the chain support frame 6 along its length direction. The cross-section of the movable support plate 7 is C-shaped, and the chain support frame 6 is embedded in the groove, so that the telescopic adjustment of the movable support plate 7 is smoother and the combination relationship between the movable support plate 7 and the chain support frame 6 is more stable and reliable.

[0036] In some embodiments, the second waist-shaped hole 702 is provided with a first threaded countersunk hole 703 and a second threaded countersunk hole 704 which are adjacent to the tail drive device 1 in sequence;

[0037] like Figure 5 As shown, when the second end is aligned with the first threaded hole 601, the second threaded hole 704 moves out of the range of the chain support frame 6 and is tangent to the end of the chain support frame 6. At this time, a bolt can be screwed into the second threaded hole 704. The bolt will pass through the second threaded hole 704 and fit tightly against the end of the chain support frame 6, thereby further limiting the end of the chain support frame 6.

[0038] like Figure 6 As shown, when the first end head and the second end head are aligned with the first threaded hole 601 and the second threaded hole 602 respectively, the first threaded counterbore 703 is also moved out of the range of the chain support frame 6 and is tangent to the end of the chain support frame 6. At this time, a bolt can be screwed into the first threaded counterbore 703. The bolt will pass through the first threaded counterbore 703 and fit tightly against the end of the chain support frame 6, thereby further limiting the end of the chain support frame 6.

[0039] In some embodiments, Figure 4 As shown, a chamfered portion 705 is provided at one end of the movable support plate 7 close to the tail drive device 1, and the chamfered portion 705 faces the slewing chain 301, so that the movable contact between the slewing chain 301 and the movable support plate 7 is smoother and more fluent, avoiding severe collision and hooking.

[0040] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
