[0002] Screw conveyors are commonly used material conveying equipment in the preparation of dry-mixed mortar.

[0003] Traditional screw conveyors typically employ a one-piece casing structure, which presents inconveniences in installation, maintenance, and replacement of the screw blades. Furthermore, if the one-piece screw pusher plate experiences localized damage after prolonged use, the entire conveyor often needs to be replaced, increasing operating costs. Therefore, it is necessary to improve existing screw conveyors used for dry-mixed mortar preparation.

[0004] Traditional screw conveyors typically use an integral shell structure, which makes maintenance inconvenient; if the integral screw pusher plate is partially damaged after long-term use, it often needs to be replaced entirely, increasing the cost of use. Utility Model Content

Figure 1-2 As shown, the device includes a fixed outer shell 1 and a drive shaft 2. The drive shaft 2 is inserted into the inner side of the fixed outer shell 1. The fixed outer shell 1 includes a lower groove shell 11, a first upper cover shell 12, and a second upper cover shell 13. A positioning kit 111 is connected to the inner side of the lower groove shell 11. The first upper cover shell 12 is located at the top of the lower groove shell 11. The second upper cover shell 13 is located at the top of the lower groove shell 11. The first upper cover shell 12 and the second upper cover shell 13 are located on both sides of the positioning kit 111. The drive shaft 2 is inserted into the inner side of the positioning kit 111. A spiral blade 23 is provided on the outer side of the drive shaft 2. Multiple sets of spiral blades 23 are provided and can be combined to form a complete spiral pusher plate.

[0030] The device adopts a split-type fixed outer shell design, including a lower groove shell 11, a first upper cover shell 12, and a second upper cover shell 13, which are connected by fixing strips 14 and reinforcing bolts 141, facilitating installation and disassembly and aiding in equipment maintenance and repair. Multiple sets of spiral vanes 23 are provided and can be combined to form a complete spiral pusher plate. When some spiral vanes 23 are damaged, only the damaged parts need to be replaced, eliminating the need for overall replacement and reducing operating costs. A notch 24 is provided between the spiral vanes 23 in the middle of the drive shaft 2 for fitting the positioning kit 111, improving the stability of the drive shaft 2 and reducing vibration and noise during conveying.

[0031] According to the appendix Figure 1-2 As shown, further, a side wing strip 112 is connected to the outer side of the lower trough shell 11, and a discharge port 113 is connected to the bottom of the lower trough shell 11.

[0032] According to the appendix Figure 1-2 As shown, the top of the first upper cover 12 is connected to a feed inlet 121, and the outer side of the first upper cover 12 is connected to a first docking wing 122 corresponding to the side wing 112.

[0033] According to the appendix Figure 1-2 As shown, the outer side of the second upper cover shell 13 is connected to a second docking wing 131 corresponding to the side wing 112.

[0034] According to the appendix Figure 1-2 As shown, the fixed outer shell 1 is further provided with a fixing strip 14, which is snapped onto the outside of the side wing strip 112 and the first docking wing strip 122 and the second docking wing strip 131. A reinforcing bolt 141 is inserted into the fixing strip 14, and the reinforcing bolt 141 passes through the side wing strip 112, the first docking wing strip 122 and the second docking wing strip 131.

[0035] According to the appendix Figure 1-2 As shown, it is particularly important to note that a positioning sleeve 15 is connected to the bottom of the lower casing 11, a motor 151 is inserted into the inner side of the positioning sleeve 15, a transmission wheel 152 is sleeved on the outer side of the output end of the motor 151, and a transmission belt 153 is sleeved on the outer side of the transmission wheel 152.

A sleeve notch 24 is provided between the spiral blades 23 in the middle of the drive shaft 2 for sleeve positioning kit 111.

[0037] Working principle: During operation, material enters the screw conveyor through the feed inlet 121. The motor 151 starts, driving the transmission wheel 152 to rotate. This, in turn, causes the transmission shaft 2 to rotate via the transmission belt 153 and the linkage wheel 21. The spiral blades 23 on the outer side of the transmission shaft 2 rotate accordingly, pushing the material from the feed inlet 121 to the discharge outlet 113, where it is finally discharged. When maintenance or replacement of the spiral blades 23 is required, simply remove the reinforcing bolts 141 and the fixing clips 14, and remove the first upper cover 12 and the second upper cover 13 to operate the spiral blades 23.
