Description

Technical Field

[0001] This utility model relates to the field of material screw conveying technology, specifically a variable diameter conveying system for a cement silo with a transmission reducer. Background Technology

[0002] As we all know, cement plays a vital role in modern construction engineering. It is not only the main binder of concrete, but also widely used in various structural and non-structural components due to its excellent mechanical properties and durability. In the use of cement, it is stored in cement silos and then discharged for use using a screw conveyor system. Screw conveyor systems generally use belt pulley drives, which are low in operating costs, but have disadvantages such as low thermal torque and unstable conveying. Screw conveyor systems are generally composed of horizontal and vertical screws with the same screw diameter. The vertical screw has a larger outer diameter, which reduces the centrifugal force of the material. This is because the larger outer diameter increases the contact area between the material and the pipe wall, dispersing the friction and thus weakening the conveying effect of cement. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a variable diameter conveying system for a cement silo with a transmission reducer. It uses a two-stage reduction gear set to drive the spiral blades to rotate, which transmits large torque and provides stable conveying. In addition, the small inner diameter of the vertical conveying pipe can better utilize centrifugal force, thus achieving a good conveying effect for cement or other materials. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a variable diameter conveying system for a cement silo with a transmission reducer, comprising a horizontal conveying pipe and a drive unit;

[0005] Horizontal conveyor pipe one: its left end is fixedly connected to horizontal conveyor pipe two. Horizontal conveyor pipe one and horizontal conveyor pipe two form an integral whole and are internally connected to a horizontal spiral conveyor plate. Horizontal conveyor pipe two is fixedly connected to a vertical conveyor pipe at its left end. Vertical spiral plate is internally connected to the vertical conveyor pipe. The inner diameter of the vertical conveyor pipe is smaller than the inner diameters of horizontal conveyor pipe one and horizontal conveyor pipe two.

[0006] Drive unit: Used to drive the rotation of the horizontal and vertical spiral conveyor blades. The motor uses a two-stage reduction gear set to drive the spiral blades to rotate, transmitting large torque and ensuring smooth conveying. In addition, the small inner diameter of the vertical conveying pipe can better utilize centrifugal force, thus achieving a good conveying effect for cement or other materials, greatly saving the cost of manual feeding. At the same time, the addition of a horizontal spiral and a vertical spiral, and the adjustable installation angle of the vertical spiral can change the discharge position, which can meet the feeding height of most mixers, improving work efficiency. It is simple to operate and convenient to use.

[0007] Furthermore, the drive unit includes a reduction housing, a motor, and a gear set. There are two reduction housings, which are respectively located at the right end of the horizontal conveying pipe and the upper end of the vertical conveying pipe. A motor is provided at the right end of the lower reduction housing and the upper end of the upper reduction housing. A gear set is provided inside each reduction housing. The horizontal spiral conveying plate, the vertical spiral plate, and the motor are all configured to cooperate with the gear set corresponding to the axial direction. The input end of the motor is electrically connected to the output end of an external control switch group, which can provide a smooth power output.

[0008] Furthermore, the gear set includes a drive shaft, an output shaft, gear one, gear two, gear three, and gear four. The output shafts are rotatably connected to the inside of the reduction housing. The lower output shaft is fixedly connected to the horizontal spiral conveyor plate, and the upper output shaft is fixedly connected to the vertical spiral plate. Gear one is provided on the outer arc surface of both output shafts. A drive shaft is rotatably connected to the inside of each reduction housing. Gear three and gear four are provided on both drive shafts. Gear four meshes with gear one inside the same reduction housing. Gear two is provided on the output shafts of both motors. Gear two meshes with gear three inside the same reduction housing. The gears are used for transmission, which transmits a large torque.

[0009] Furthermore, the number of teeth of gear two is less than the number of teeth of gear three, and the number of teeth of gear four is less than the number of teeth of gear one, which allows for two-stage speed reduction.

[0010] Furthermore, both the left end of the first horizontal conveying pipe and the right end of the second horizontal conveying pipe are provided with flanges, and the two flanges are fixedly connected by bolts, which facilitates the disassembly of the first horizontal conveying pipe and the second horizontal conveying pipe.

[0011] Furthermore, the vertical conveying pipe has a downwardly inclined discharge pipe at the upper end of the discharge port, and the horizontal conveying pipe has a connecting pipe at the right end of the outer arc surface of the horizontal conveying pipe to facilitate the flow of materials.

[0012] Furthermore, two support seats are provided on the outer arc surfaces of both the first and second horizontal conveying pipes to facilitate the fixing of the first and second horizontal conveying pipes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The variable diameter conveying system of the transmission reducer of this cement silo has the following advantages:

[0014] The motor uses a two-stage reduction gear set to drive the spiral blades to rotate, which transmits large torque and ensures smooth conveying. In addition, the small inner diameter of the vertical conveying pipe can better utilize centrifugal force, thus achieving a good conveying effect for cement or other materials and greatly saving the cost of manual feeding.

When the two motors 62 operate, their output shafts drive the second gear 634 to rotate, and the second gear 634 drives the meshing third gear 635. 5. Gear 3 635 drives gear 4 636, which is coaxially arranged, to rotate via transmission shaft 631. Gear 4 636 drives gear 1 633, which meshes with it, to rotate. Gear 1 633 drives output shaft 632 to rotate.
