Description

Technical Field

[0001] This utility model provides a mortar storage bin anti-clogging device, belonging to the field of mortar storage technology. Background Technology

[0002] Mortar is a binding material used in bricklaying. It is made by mixing sand and binders (cement, lime paste, clay, etc.) with water in a certain proportion. It is also called mortar or cement paste. Common types of mortar include cement mortar, mixed mortar (or cement-lime mortar), lime mortar, and clay mortar. Currently, mortar storage silos are usually set up on construction sites to store large quantities of mortar for workers to use.

[0003] Existing mortar storage silos can basically meet normal usage needs. A screw conveyor is usually installed at the bottom discharge port of the mortar storage silo to directly transport mortar. It generally includes an outer shell, a screw conveyor auger that rotates inside the outer shell, and a motor for driving the screw conveyor auger. A gate valve is installed at the discharge port at one end of the bottom of the screw conveyor shell to control the opening and closing of the discharge port. When unloading is required, the motor is started to drive the screw conveyor auger to rotate. The mortar in the storage silo enters the outer shell through the discharge port. The rotation of the screw conveyor auger inside the conveying shell can continuously transport the mortar towards the discharge port, and finally the mortar inside the outer shell is discharged from the discharge port.

[0004] Based on the above research and existing technology, although direct conveying of mortar via a screw conveyor is convenient and relatively effective in preventing mortar blockage during unloading, the mortar in the storage silo still tends to accumulate at the bottom due to the limited size of the discharge port, leading to blockage. Therefore, the anti-blocking effect during unloading is still insufficient. Accordingly, this invention provides a mortar storage silo anti-blocking device. Utility Model Content

[0005] The technical problem solved by this utility model is that the discharge port size is limited, and the mortar is directly transported by the screw conveyor. The mortar in the lower part of the storage bin is still easy to accumulate, causing the mortar entering the discharge port to block. The anti-blocking effect during unloading is still not good enough.

[0006] To solve the technical problem, the present invention provides the following technical solution: a mortar storage bin anti-clogging device, comprising a storage bin, a discharge port at the bottom of the storage bin, an anti-clogging discharge component at the bottom of the discharge port, the anti-clogging discharge component comprising a vertical inclined pipe, a conveying shell at the bottom port of the vertical inclined pipe, a spiral conveying auger inside the conveying shell, a rotating rod inside the vertical inclined pipe, spiral blades placed in the discharge port and the vertical inclined pipe on the rod, scrapers symmetrically arranged on both sides of the top of the rotating rod that contact the inner bottom wall of the storage bin, a plurality of blades on the top of the scrapers, and a driving part on the conveying shell for driving the rotating rod and the spiral conveying auger to rotate.

[0007] Furthermore, both ends of the spiral conveyor are rotatably connected to the two inner side walls of the material conveying shell via bearings.

[0008] Furthermore, the bottom of the side wall of the vertical inclined pipe is provided with a support pipe that passes through the rotating rod, and the support pipe is provided with a bearing 2 that is rotatably connected to the rotating rod.

[0009] Furthermore, the drive unit includes a transmission box fixedly mounted on one side wall of the conveying housing. One end of the screw conveyor is inserted into the transmission box and is provided with a main bevel gear. The lower end of the rotating rod is rotatably connected to the top of the transmission box, and the bottom of the rotating rod is inserted into the transmission box. The bottom of the rotating rod is provided with a driven bevel gear that meshes with the main bevel gear.

[0010] Furthermore, the drive unit also includes a motor fixedly mounted on the outer wall of the transmission box, the output end of which is inserted into the transmission box and fixedly connected to the rod end of the screw conveyor inserted into the transmission box.

[0011] Furthermore, the top port of the vertical inclined pipe is fixedly connected to the bottom of the discharge port by bolts, the top of the conveying shell is provided with an inlet at the end near the storage bin, the bottom port of the vertical inclined pipe is fixedly connected to the top of the inlet by bolts, and the top of the conveying shell is provided with a discharge port at the end away from the storage bin.

[0012] The beneficial effects of this utility model are:

[0013] The anti-clogging discharge component, driven by the drive unit, enables the screw conveyor and rotating rod to rotate. The rotating rod drives the spiral blades and scraper to rotate. The rotation of the spiral blades effectively prevents mortar from clogging the discharge port and the vertical and inclined pipes. The scraper rotating around the rotating rod cleans the mortar on the bottom wall of the storage bin, resulting in cleaner unloading. At the same time, the rotation of the scraper drives several blades to rotate around the rotating rod, which agitates the mortar in the lower part of the storage bin, keeping it in a flowing state and effectively preventing mortar sedimentation. The rotation of the screw conveyor inside the conveying shell continuously transports the mortar towards the discharge port, ultimately allowing the mortar inside the conveying shell to be discharged from the discharge port, resulting in better anti-clogging effect during unloading.

[0025] The principle of this utility model

[0026] When unloading mortar from storage chamber 1, the mortar in storage chamber 1 is conveyed to the conveying shell 5 through discharge port 2 and vertical inclined pipe 4 via anti-clogging discharge component 3. Under the action of drive unit 10, motor 17 is started to rotate screw conveyor 6 and rotating rod 7. The rotation of rotating rod 7 drives the spiral blade 8 and scraper 9 to rotate. The rotation of spiral blade 8 can effectively prevent mortar from clogging in discharge port 2 and vertical inclined pipe 4. The rotation of scraper 9 around rotating rod 7 can clean the mortar on the inner bottom wall of storage chamber 1, making unloading cleaner. At the same time, the rotation of scraper 9 drives several blades 20 to rotate around rotating rod 7, which can stir the mortar in the lower part of storage chamber 1 to keep it in a flowing state, effectively preventing mortar sedimentation. The rotation of screw conveyor 6 in conveying shell 5 can continuously convey mortar towards discharge port 19, and finally the mortar in conveying shell 5 is discharged from discharge port 19, resulting in better anti-clogging effect during unloading.
