Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, and in particular to a novel screw conveyor. Background Technology

[0002] A screw conveyor, also known as an auger conveyor, is a continuous conveying device that uses rotating helical blades to push bulk materials forward along a fixed shell, thereby achieving horizontal, inclined, or even vertical material conveying.

[0003] However, existing screw conveyors have problems with the inlet sealing during feeding, which causes dust to overflow from the inlet, polluting the environment and affecting the health of operators.

[0004] To address these issues, we have developed a novel screw conveyor. Utility Model Content

[0005] This invention provides a novel screw conveyor that solves the problems mentioned in the background section.

[0006] This utility model provides a novel screw conveyor, including a screw conveyor body and a feed inlet. A sealing assembly is installed at the top of the feed inlet, and the sealing assembly includes a first sealing cover and a second sealing cover inserted into the top of the feed inlet.

[0007] Preferably, the outer side of the screw conveyor body is threaded with a fixed seat, and the surface of the screw conveyor body is provided with a first insertion port.

[0008] Preferably, the surface of the first sealing cover is threadedly connected to a base, and a limiting piece is welded to the surface of the base.

[0009] Preferably, a locking rod is sleeved on the inner side of the base, and a U-shaped rod is welded to the surface of the locking rod.

[0010] Preferably, the bottom ends of the first sealing cover and the second sealing cover are both fixedly connected to a first insert block, the surface of the first sealing cover is provided with a second insertion port, and the surface of the second sealing cover is fixedly connected to a second insert block.

[0011] Preferably, the feed inlet is located at the top of the screw conveyor body, and the discharge outlet is located on one side of the screw conveyor body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When installing the sealing assembly, firstly, insert the first insert block at the lower end of the first sealing cover into the corresponding first insert at the upper end of the feed inlet to achieve initial positioning. Next, insert the first insert block at the bottom of the second sealing cover into the first insert, and simultaneously insert the second insert block on one side into the second insert, so that the first and second sealing covers are aligned and initially fixed above the feed inlet. Then, the operator moves the U-shaped rod to disengage it from the limiting plate, releasing the temporary limiting state. Immediately afterwards, push the locking rod downward to insert it into the fixing seat, thereby firmly locking the first and second sealing covers onto the feed inlet, forming a sealed dustproof cavity. This method effectively prevents dust from overflowing from the feed inlet during material conveying, improving the sealing performance of the equipment and the safety of the working environment.

[0016] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] See Figure 1-4A novel screw conveyor includes a screw conveyor body 1 and a feed inlet 2. A sealing component 3 is installed at the top of the feed inlet 2. The sealing component 3 includes a first sealing cover 301 and a second sealing cover 302 inserted into the top of the feed inlet 2. The first sealing cover 301 and the second sealing cover 302 cooperate to form a closed space to prevent dust from overflowing.

[0018] Furthermore, a fixed seat 303 is threadedly connected to the outer side of the screw conveyor body 1, and a first insertion port 304 is provided on the surface of the screw conveyor body 1. The first insertion port 304 is used in conjunction with the first insertion block 309.

[0019] Furthermore, the surface of the first sealing cover 301 is threadedly connected to the base 305, and the surface of the base 305 is welded with a limiting piece 306. The surface of the second sealing cover 302 is also threadedly connected to the base 305, the limiting piece 306, the locking rod 307, and the U-shaped rod 308.

[0020] Furthermore, a locking rod 307 is sleeved on the inner side of the base 305, and a U-shaped rod 308 is welded to the surface of the locking rod 307. The locking rod 307 is inserted into the fixing seat 303, thereby connecting the first sealing cover 301 and the second sealing cover 302 to the feed port 2.

[0021] Furthermore, the bottom ends of the first sealing cover 301 and the second sealing cover 302 are both fixedly connected to the first insert block 309. The surface of the first sealing cover 301 is provided with a second insertion port 310, and the surface of the second sealing cover 302 is fixedly connected to the second insert block 311. The second insert block 311 is inserted into the second insertion port 310, thereby connecting the first sealing cover 301 and the second sealing cover 302.

[0022] Furthermore, the feed inlet 2 is located at the top of the screw conveyor body 1, and the discharge outlet 4 is provided on one side of the screw conveyor body 1, through which the material leaves the screw conveyor.

[0023] As can be seen from the above technical solution, when installing the sealing assembly 3, firstly, the first insert 309 at the lower end of the first sealing cover 301 is inserted into the corresponding first insert 304 at the upper end of the feed inlet 2 to achieve initial positioning. Next, the first insert 309 at the bottom of the second sealing cover 302 is also inserted into the first insert 304, while simultaneously embedding the second insert 311 on one side into the second insert 310, so that the first sealing cover 301 and the second sealing cover 302 are aligned and initially fixed above the feed inlet 2. Then, the operation... The operator moves the U-shaped rod 308 to disengage it from the limiting plate 306, releasing the temporary limiting state. Then, the operator pushes the locking rod 307 downward, inserting it into the fixed seat 303. This securely locks the first sealing cover 301 and the second sealing cover 302 onto the feed inlet 2, forming a sealed dustproof cavity. This effectively prevents dust from overflowing from the feed inlet during material conveying, improving the equipment's sealing performance and the safety of the working environment. This completes the use of a new type of screw conveyor.
