[0028] The following is a brief introduction to the specific structure of each institution:

[0029] See also Figure 2 and Figure 3 The lifting crawler 2 includes a motor 18, a crawler 19 and a crawler track 110. Two groups of pulleys are horizontally arranged on the side of the crawler 19 facing the crawler track 110. One group is close to the upper part, called the first group of pulleys 12, and the other group is close to the lower part, called the second group of pulleys 14. The first group of pulleys 12 is arranged in the first slideway, and the second group of pulleys 14 is arranged in the second slideway. The top of the first slideway is arranged to deviate from the crawler track 110 in an arc turn. The top of the first slideway is a blind end, which deviates toward the bottom of the crawler track 110. The blind end is called a limit groove 13. A reversing wheel 16 is arranged on the top of the second slideway. The crawling bucket 19 is symmetrically provided with hanging ears 15 on both horizontal sides, and the hanging ears 15 are tied or welded with cables 11. The cables 11 pass through the reversing wheel 16 and are connected to the reel 17 arranged below the crawling road 110. The cables 11 are wound on the reel 17, and the reel 17 is connected to the motor 18 for driving. The motor 18 drives the reel 17 to rotate and rewind. The first group of pulleys 12 is provided with two pulleys, which are arranged on the left and right outer sides of the crawling bucket 19, and the second group of pulleys 14 is provided with two pulleys, which are arranged near the bottom of the crawling bucket 19 on both sides. The motor 18 is a forward and reverse motor 18. When the crawling bucket 19 is placed horizontally, the top surface is fully open, and there is a horizontal section from the side close to the crawling road 110 to the opposite side, and then there is a transition section that tilts downward, and finally a horizontal section. The length of the side of the crawling bucket 19 close to the crawling road 110 is longer than the height of the opposite side, and the opposite side is arranged vertically. The utility model adopts an inclined lifting crawler bucket 2, which provides installation space for the motor 18 on the one hand, and facilitates the crawler bucket 19 to connect with the hopper of the hydraulic reciprocating feeder 1 for material dumping.

[0030] The working process of the lifting crawler 2 is as follows: when loading, the crawler 19 is located at Figure 2 At position A, the crawler 19 is open upwards, and the hydraulic reciprocating feeder 1 is located Figure 2 At position A', the hydraulic reciprocating feeder 1 dumps the material toward the crawler bucket 19. When the material is loaded, the hydraulic reciprocating feeder 1 moves from Figure 2 The position of A' in the middle is returned to the position of B'. The crawler 19 is moved from Figure 2 The first group of pulleys 12 is stuck in the limit groove 13 and no longer moves, while the second group of pulleys 14 continues to move upward under the pulling of the cable 11, until the cable 11 pulls the crawling bucket 19 to the top of the crawling path 110, and the crawling bucket 19 flips over. Figure 2At position B, all the materials in the bucket 19 are dumped out. At this time, the bucket 19 is stuck and the rope cannot be pulled. The motor 18 cannot be rotated. The stroke of the forward and reverse motor 18 is set, or a sensor is set to switch the forward and reverse motor 18. At this time, the forward and reverse motor 18 stops and the dwell time of the forward and reverse motor 18 is set. This dwell time is enough for the materials in the bucket 19 to be dumped. Then the motor 18 is reversed and the bucket 19 descends to its original position. Since the bucket 19 is usually made of steel and has a large size and a weight of more than 50 kilograms, and the crawling walkway 110 has a large inclination angle, it will automatically descend to its original position under the action of gravity after the rope is loosened. When the bucket 19 reaches Figure 2 After reaching position A, the motor 18 is stopped through stroke control or sensor recognition is set at A, and the hydraulic reciprocating feeder 1 recharges the crawler bucket 19, sets the dwelling time of the crawler bucket 19 at A, and works in a cycle in sequence.

[0031] The hydraulic reciprocating feeder 1 is provided with two hydraulic rods, one end of each of which is fixed to both sides of the lifting crawler bucket 2, and the other end is fixed to the outer side of the upper edge of the hopper of the hydraulic reciprocating feeder 1. When the hopper of the hydraulic reciprocating feeder 1 is tilted toward the lifting crawler bucket 2 to pour materials, the lower inner wall and the bottom inner wall in the hopper of the hydraulic reciprocating feeder 1 are both facing downward.

[0032] It also includes a hopper supporting mechanism of the hydraulic reciprocating feeder 1. When the hydraulic reciprocating feeder 1 is waiting for loading, the hopper opening of the hydraulic reciprocating feeder 1 faces upward, and the hopper of the hydraulic reciprocating feeder 1 is placed in the hopper supporting mechanism of the hydraulic reciprocating feeder 1. Edges are provided on both sides of the hopper of the hydraulic reciprocating feeder 1, and the edges can be just pressed on the hopper supporting mechanism of the hydraulic reciprocating feeder 1. A base of the same shape for supporting the hopper of the hydraulic reciprocating feeder 1 is also provided at the bottom of the hopper supporting mechanism of the hydraulic reciprocating feeder 1, which plays a role in fixing the position of the hopper of the hydraulic reciprocating feeder 1 during the loading process, and will not pull the hydraulic rod, thereby improving the safety and service life of the hydraulic reciprocating feeder 1.

[0033] A plurality of legs 7 are provided below each mechanism of the utility model for support and fixation as required.

[0034] The term “connection” as used in this application may mean a direct connection between components or an indirect connection between components via other components.
