[0035] In the related art, the screw conveyor is an automated device widely used in industrial production, mainly used for continuous conveying and control of materials, especially in the unloading operations of pulverized coal or cement clinker at ports. In actual applications, sometimes the material needs to be conveyed over a relatively long distance in the horizontal direction. For this reason, the existing screw conveyor uses a relatively long screw blade shaft to achieve long-distance conveying of materials. However, the excessive length of the screw blade shaft makes it difficult to ensure its coaxiality with the conveying pipe, and it is difficult to install. The end of the screw blade shaft is prone to scraping against the conveying pipe, resulting in jamming and even damage to the screw blade shaft. Therefore, manual maintenance is often required, which reduces the unloading efficiency.

[0036] For this reason, the present utility model provides a horizontal screw conveyor, which can improve the stability of equipment operation and the efficiency of material conveying.

[0037] Refer to Figures 1 to 5, in some embodiments of the present utility model, the horizontal screw conveyor is used to convey pulverized coal, cement clinker or other granular materials in the horizontal direction. Specifically, the horizontal screw conveyor includes a conveying component 200, a driving component 100 and an intermediate support bearing component 300. The conveying component 200 includes a conveying pipe 210 and a screw blade shaft 220. A spiral blade is arranged on the outer wall of the screw blade shaft 220. The screw blade shaft 220 is rotatably installed in the conveying pipe 210. A conveying cavity 211 is formed inside the conveying pipe 210. An inlet 212 and an outlet 213 are respectively opened at both ends of the conveying cavity 211. Among them, the inlet 212 is located on the upper side of one end of the conveying cavity 211, and the outlet 213 is located on the lower side of one end of the conveying cavity 211, so as to facilitate feeding and discharging. The driving component 100 includes a driving motor and a transmission member 110. The driving motor can drive the screw blade shaft 220 to rotate through the transmission member 110, so that the screw blade shaft 220 can drive the material to move in the conveying cavity 211. Both the conveying pipe 210 and the screw blade shaft 220 are provided with a plurality of them. The plurality of conveying pipes 210 are connected in sequence in the horizontal direction. An intermediate support bearing component 300 is installed between two adjacent conveying pipes 210. Both ends of the intermediate support bearing component 300 are respectively connected to the screw blade shafts 220 in the two conveying pipes 210. Therefore, linkage can be realized between the plurality of screw blade shafts 220, and the coaxiality of the screw blade shaft 220 and the conveying pipe 210 will be higher, and the installation is more convenient. When conveying materials, the materials enter the conveying cavity 211 from the inlet 212. The driving motor drives the first screw blade shaft 220 to rotate through the transmission member 110. The first screw blade shaft 220 drives the subsequent screw blade shafts 220 to rotate in sequence through the intermediate support bearing component 300, so as to drive the materials to move axially along the screw blade shaft 220 in the conveying cavity 211. When the materials move to the end of the conveying cavity 211, the materials can be discharged from the outlet 213, so as to realize the long-distance conveying of the materials in the horizontal direction.

[0038] Referring to Figure 1 , for the horizontal screw conveyor according to the embodiment of the present utility model, by providing a conveying component 200, a driving component 100 and an intermediate support bearing component 300, the conveying component 200 includes multiple sections of components, and each section of component includes a conveying pipe 210 and a screw blade shaft 220.

The screw blade shafts 220 in adjacent conveying pipes 210 are connected through the intermediate support bearing component 300, so as to realize the continuous conveying of materials between multiple conveying pipes 210. Therefore, it can avoid the problem that one end of the screw blade shaft 220 is easily scratched and stuck or even damaged by the conveying pipe 210 due to the use of a longer screw blade shaft 220 in the prior art. The horizontal screw conveyor of the present utility model can realize the long-distance conveying of materials, and at the same time can reduce the installation difficulty of the equipment and improve the operation stability of the equipment, thus being beneficial to improving the material conveying efficiency.

[0039] Reference Figure 3 Figure 3 , it can be understood that in some embodiments of the present utility model, the intermediate support bearing assembly 300 includes a bearing housing 310, a rotating shaft 330 and a bearing seat 320. Flange plates can be provided at both ends of the bearing housing 310, so that the bearing housing 310 can be bolted to the end of the adjacent conveying pipe 210 through the flange plates. Of course, a gasket can also be provided between the flange plate and the end of the conveying pipe 210, so as to avoid the leakage of material dust from the junction of the two to the outside. The bearing seat 320 is detachably installed in the bearing housing 310, the rotating shaft 330 is rotatably installed in the bearing seat 320, and both ends of the rotating shaft 330 are respectively connected to two adjacent screw blade shafts 220. Therefore, when one of the screw blade shafts 220 rotates, it can drive the other adjacent screw blade shaft 220 to rotate through the rotating shaft 330, thereby driving the material to move in the conveying pipe 210 and realizing the horizontal transportation of the material.

Specifically, the inner wall of the rotating cavity can be provided with a bearing bush, so as to reduce the rotation resistance of the rotating shaft 330. In addition, the size of the movable seat 321 can be designed to be much smaller than that of the fixed seat 322, so that a large gap can be formed above the movable seat 321, which is beneficial to the passage of materials.

[0041] Reference Figure 5 Figure 5 , it should be noted that in order to realize the connection between the rotating shaft 330 and the screw blade shaft 220, in some embodiments of the present utility model, the rotating shaft 330 is provided with a rotating part 331 and a connecting part 332.

Specifically, the support portion 323 is roughly semicircular, and its bottom can be supported by abutting against the inner wall of the bearing box 310. Of course, the support portion 323 can also be provided with a rib plate to improve its structural strength. Since a hollow position is formed between the support portion 323 and the bearing portion 324, the material can flow through the hollow position, thereby reducing the resistance of the material moving between the conveying pipes 210, which is conducive to improving the conveying efficiency of the material.

[0043] Reference Figure 3 It can be understood that in order to enable the intermediate support bearing assembly 300 to work stably for a long time, in some embodiments of the present invention, the intermediate support bearing assembly 300 also includes an oil pipe 340, and the oil pipe 340 is connected to the movable seat 321. By regularly delivering lubricating oil to the oil pipe 340, the rotation between the rotating shaft 330 and the bearing seat 320 is smoother, thereby reducing the wear caused by the rotation.

The tail support assembly 400 is connected to the end of the conveying assembly 200 away from the drive assembly 100. The tail support assembly 400 is provided with a bearing assembly and a rotatable support shaft 410. One end of the support shaft 410 is rotatably installed in the bearing assembly, and the other end of the support shaft 410 is fixedly connected to the screw blade shaft 220, so that the screw blade shaft 220 can be supported at both ends of the entire conveying assembly 200, which is beneficial to improving the rotation stability of the screw blade shaft 220 and the force uniformity of the conveying assembly 200.
