DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example: Reference Figure 1-8 The pit spiral feeding device shown includes a silo 1 and a conveying pipe 2. The silo 1 is a conical structure. The conveying pipe 2 is connected to the silo 1 and is connected to a conveying motor through a synchronous belt and a synchronous wheel at the bottom end of the conveying pipe 2. The conveying motor controls the auger to rotate in the conveying pipe 2, and the material put into the silo 1 enters from the feed port on the conveying pipe 2, and is conveyed to the outlet at the top of the conveying pipe 2 by the auger for discharge.

[0029] As an implementation method in this embodiment, a connecting seat 24, a fixing seat 22, and a stabilizing seat 21 are provided on the outer wall of the conveying pipe 2 from top to bottom, and the limiting seats 23 are symmetrically arranged on both sides of the fixing seat 22 with the fixing seat 22 as the center line;

[0030] The connecting shaft 10 is rotatably connected to the connecting seat 24. In order to enable the connecting shaft 10 to rotate, the top of the connecting shaft 10 passes through synchronous wheels provided at its end and the end of the auger. The two sets of synchronous wheels are connected by a synchronous belt, thereby transmitting the power generated by the conveying motor to the connecting shaft 10 (a dust cover is provided here to protect the synchronous belt);

[0031] A reciprocating rod 9 is rotatably connected to the fixed seat 22. The top of the reciprocating rod 9 is coaxially connected to the connecting shaft 10. A bidirectional spiral groove is provided on the outer wall of the reciprocating rod 9. The bidirectional spiral groove is adapted to the adjusting member 8. Under the limit of the connector 5 (the connector 5 is limited by the limit seat 23 for the movement trajectory), the adjusting member 8 can reciprocate on the bidirectional spiral groove.

[0032] The bottom end of the connector 5 is detachably connected to the pull rod 4 sliding on the stable seat 21, so that when the connector 5 moves, the pull rod 4 can be controlled to slide on the stable seat 21, so that the material cover 3 connected to the bottom end of the pull rod 4 can frequently open and close the feed port on the feed pipe 2, thereby destroying the balance of the material.

[0033] As an implementation method in this embodiment, the connector 5: a slide groove 61 is provided on the outer wall of the reciprocating member 6, and the limit seat 23 is an L-shaped structure, and its horizontal section is adapted to the slide groove 61, and in order to further limit the state of the reciprocating member 6, the horizontal section of the limit seat 23 is a rectangular structure, and a through hole 62 is provided on the top of the reciprocating member 6. The adjusting member 8 rotatably connected in the through hole 62 cooperates with the reciprocating rod 9 to make the reciprocating member 6 slide on the limit seat 23; in order to facilitate quick disassembly and assembly with the pull rod 4, a hook 7 is hinged at the bottom end of the reciprocating member 6, and the hook 7 is adapted to the pull rod 4. When in use, the hook on the hook 7 is placed on the vertical section of the pull rod 4 to achieve the connection between the two.

[0034] As an implementation method in this embodiment, the adjusting member 8: the connecting rod 82 is rotatably connected to the through hole 62, and the steering head 81 is rotatably connected to the bottom end of the connecting rod 82, and the steering head 81 is slidably connected to the bidirectional spiral groove. Therefore, when the reciprocating rod 9 rotates, the steering head 81 slides in the bidirectional spiral groove, driving the reciprocating member 6 to perform reciprocating motion.

[0035] As an implementation method in this embodiment, the T-shaped connector at the bottom end of the pull rod 4 is matched with the connecting groove 31 on the material cover 3 to achieve quick installation between the pull rod 4 and the material cover 3.

[0036] The working principle of this utility model is as follows: the conveying motor drives the auger in the conveying pipe 2 to rotate under the action of the synchronous wheel and the synchronous belt, and then transmits the power of the auger to the connecting shaft 10 through the synchronous belt and the synchronous wheel at the top, and makes the connecting shaft 10 rotate on the connecting seat 24. The rotating connecting shaft 10 drives the reciprocating rod 9 coaxially connected with it to rotate on the two sets of fixed seats 22; the rotating reciprocating rod 9 cooperates with the steering head 81 through the bidirectional spiral groove provided on the outer wall, so that the steering head 81 reciprocates on the reciprocating rod 9, so the steering head 81 drives the reciprocating rod 9 through the connecting rod 82. The reciprocating member 6 moves. In order to stabilize the movement trajectory of the reciprocating member 6, an L-shaped limit seat 23 is provided on the outer side of the fixed seat 22. The horizontal section of the limit seat 23 cooperates with the slide groove 61 on the reciprocating member 6, so that the reciprocating member 6 slides on the limit seat 23; the sliding reciprocating member 6 is connected to the pull rod 4 through the hook 7 hinged at the bottom end, thereby driving the pull rod 4 to slide on the stabilizing seat 21, and the pull rod 4 drives the material cover 3 to move, so that the feed port on the feeding pipe 2 is switched between an open and a closed state. The moving material cover 3 destroys the balance of the material in the silo 1 to avoid arching.
