Abstract

The auger quick connector belongs to the technical field of agricultural machinery, and two shells are connected by screwing. The left shell has a left auger fixing cylinder. The left auger fixing cylinder is provided with a left auger screw rod and a left nut for pressing the inner end of the left auger. The left auger fixing cylinder is fixed with a left support shaft, and the left support shaft is supported on a left inner rib plate fixed in the left shell through a left bearing. The left support shaft is fixed with a left fixing disc on the right side. The right side structure is symmetrical and the same. The left fixing disc and the right fixing disc are connected through concave-convex clamping. The left fixing disc edge is provided with a protrusion, and the right fixing disc edge is provided with a groove.

The connector can stably connect two sections of augers through stable connecting pieces.

Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and specifically relates to a nylon hose auger quick connector. Background Technology

[0002] Grain suction machines are a new type of agricultural and industrial machinery that uses augers to transport granular materials. They are suitable for bulk conveying of various small granular materials such as grains and plastics. Utilizing a pipeline layout, materials can be conveyed horizontally, inclined, or vertically. Operation is simple and convenient, and a single machine can complete the conveying task independently. However, different working scenarios require augers of different lengths, necessitating the fixing of two auger sections together. Currently, the commonly used connection method is welding, which is prone to breakage during use. Utility Model Content

[0030] The auger quick connector includes a left housing 1 and a right housing 2.

[0031] Both the left shell 1 and the right shell 2 are cylindrical bodies with openings at both ends, and are arranged on the same axis relative to each other.

[0032] The right opening of the left housing 1 and the left opening of the right housing 2 are fixedly connected by threads.

[0033] The left housing 1 contains a cylindrical left auger fixing cylinder 4 arranged coaxially.

[0034] The left auger fixing cylinder 4 has four holes for the left auger screw 18 (U-shaped screw) to pass through, and two left nuts 5 are tightened at the end to press the inner end of the left auger 6.

[0035] The left auger fixing cylinder 4 contains a radially fixed left support plate 23, on which a left support shaft 9 is fixed. The left support shaft 9 is coaxially arranged with the left auger fixing cylinder 4.

[0036] The left support shaft 9 is supported by the left bearing 8 on the left inner stiffening plate 3 fixed inside the left housing 1.

[0037] A left fixed plate 10 is fixed to the right side of the left support shaft 9. The left fixed plate 10 is a disc.

[0038] The right housing 2 contains a cylindrical right auger fixing cylinder 17 arranged coaxially.

[0039] The right auger fixing cylinder 17 has four holes for the right auger screw (U-shaped screw) to pass through, and two right nuts are tightened at the end to press down the inner end of the right auger 22.

[0040] The right auger fixing cylinder 17 has a radially fixed right support plate inside its left side, and a right support shaft 7 is fixed on the right support plate. The right support shaft 7 is coaxially arranged with the right auger fixing cylinder 17.

[0041] The right support shaft 7 is supported by the right bearing on the right inner stiffening plate fixed inside the right housing 1.

[0042] A right fixed plate 12 is fixed to the left side of the right support shaft 7. The right fixed plate 12 is a disc.

[0043] Left fixed plate 10 and right fixed plate 12 are connected by a concave-convex locking mechanism.

[0044] In this embodiment, the left fixing plate 10 has multiple (three) protrusions 13 on its edge, and the circular right fixing plate 12 has multiple (three) grooves 14 on its edge.

[0045] The left inner stiffening plate 3 includes multiple left radial stiffening plates 11 and a left inner support tube 19.

[0046] The outer edge of the left radial stiffener 11 is fixed to the circumference of the right opening of the left housing 1. The inner edge of the left radial stiffener 11 is fixed with a variable diameter left inner support tube 19. The smaller diameter part on the left side of the left inner support tube 19 is used to support the left bearing 8, and the larger diameter part on the left side of the left inner support tube 19 is used to accommodate the left fixed plate 10.

[0047] The right side structure is symmetrical:

[0048] The right inner stiffener plate includes multiple right radial stiffener plates and a left inner support tube.

[0049] The outer edge of the right radial stiffener is fixed to the circumference of the left opening of the right shell 2. The inner edge of the right radial stiffener is fixed with a variable diameter right inner support tube. The smaller diameter part on the right side of the right inner support tube is used to support the right bearing, and the larger diameter part on the left side of the right inner support tube is used to accommodate the right fixed plate 12.

[0050] The outer edges of the left inner support tube 19, the right inner support tube, the left auger fixing cylinder 4, and the right auger fixing cylinder 17 have the same diameter, forming a complete cylinder, which can prevent the transported particles from entering the two fixing discs and the bearing positions on both sides.

[0051] The usable connection structure in this embodiment is:

[0052] The edge of the right housing 2 is hinged to multiple screws 15 via multiple shafts, and the edge of the left housing 1 has multiple screw grooves 16.

[0053] Rotate the screw 15 into the screw groove 16, and then lock it on the outside with the lock nut 24.

[0054] Alternatively, the openings on the edges of the left housing 1 and the right housing 2 can be directly fixed with screws and nuts.

[0055] Furthermore, the left shell 1 is a variable-diameter shell with a smaller diameter on the left and a larger diameter on the right.

[0056] The right shell 2 is a variable diameter shell with a smaller diameter on the right side and a larger diameter on the left side.

[0057] This variable diameter design facilitates the accommodation of two fixed discs and allows grain particles to pass through the middle area.

[0058] The left nylon hose 20 is fixed to the left opening of the left housing 1 by the left hose clamp 21.

[0059] The right nylon hose is fixed to the right opening of the right housing 2 by the right hose clamp.

[0060] The working principle is as follows:

[0061] The left auger screw 18 fixes the inner end of the left auger 6 to the left auger fixing cylinder 4 through the left nut 5.

[0062] The fixed structures on the right side are identical.

[0063] The left fixed plate 10 and the fixed plate 12 rotate and are locked in place by the protrusion 13 and the groove 14.

[0064] The left auger 6 drives the left auger fixing cylinder 4, the left support shaft 9, the protrusion 13 and the groove 14 to drive the right fixing plate 12, the right support shaft 23, the right auger fixing cylinder 17 and the right auger 22, thus firmly connecting the two augers together.
