Description

Technical Field

[0001] This utility model relates to the field of thermal insulation mortar production technology, specifically to a raw material conveying device for thermal insulation mortar production. Background Technology

[0002] The main raw materials of thermal insulation mortar include mortar sand, polymer powder, insulation agent, and additives. Mortar sand is the basic aggregate of thermal insulation mortar, polymer powder is the binder of thermal insulation mortar, insulation agent is the additive that gives thermal insulation mortar good thermal insulation performance, and additives are used to increase the plasticity and stability of mortar. These raw materials need to be mixed in a certain proportion to form thermal insulation mortar. After the raw materials for thermal insulation mortar production are produced, they need to be transported in reverse to the transfer vehicle by conveying equipment.

[0003] In the prior art, patent CN201820126758.3 discloses a raw material lifting device for thermal insulation mortar production, including a base plate and a support block. A rectangular frame is fixedly connected to one side of the top of the base plate. A first motor is fixedly connected to the bottom of the inner wall of the rectangular frame through a connecting block. A first pulley is sleeved on the outer surface of one end of the output shaft of the first motor. A first support frame is fixedly connected to the top of the inner wall of the rectangular frame. A movable shaft is rotatably connected to one side of the first support frame through a bearing. One end of the movable shaft passes through the first support frame and extends to the other side of the first support frame.

[0004] The above-mentioned conveying device for raw materials used in the production of thermal insulation mortar has some problems in actual operation. After the raw materials for the production of thermal insulation mortar are poured into the elevator, some stubborn polymer powder cannot be effectively dispersed, which affects the smoothness of the conveying of the raw materials for the production of thermal insulation mortar. Therefore, we propose a conveying device for raw materials used in the production of thermal insulation mortar. Utility Model Content

[0023] Please see Figure 1-3 This embodiment provides a technical solution: a raw material conveying device for thermal insulation mortar production, including a mixing and feeding mechanism 3 and a driving mechanism 5;

[0024] Bottom auger 1: A feeding box 2 is fixedly connected to the upper right feed inlet. A feeding hopper 7 is provided at the right end of the feeding box 2. An inclined support 8 is fixedly connected to the outer surface of the bottom auger 1.

The top mounting frame 32 is fixedly connected to the upper side of the feeding box 2. The central support cylinder 31 is fixedly connected to the middle of the upper side wall of the feeding box 2. The conveying drive rod 34 is rotatably connected inside the central support cylinder 31. The upper end of the conveying drive rod 34 is fixedly connected to the reciprocating screw 33.

The three distributing insert cylinders 39 each have a side stirring rod 38 movably fitted inside. The upper ends of the three side stirring rods 38 are rotatably connected to the side wall of a reciprocating moving frame 37. The stirring and feeding mechanism 3 also includes a conveying spiral blade 35, which is fixedly connected to the lower side of the outer arc surface of the conveying drive rod 34. The lower ends of the outer arc surfaces of the three side stirring rods 38 are also fixedly connected to the conveying spiral blades 35. The volume of the middle conveying spiral blade 35 is larger than that of the three side conveying spiral blades 35. The upper end of the top mounting frame 32 is fixedly connected to the conveying motor 4. The output shaft of the conveying motor 4 is fixedly connected to the upper end of the reciprocating lead screw 33. The input end of the conveying motor 4 is electrically connected to the output end of the controller 9. The lower surface of the reciprocating moving frame 37 is fixedly... The feed hopper 2 is fixedly connected to three evenly distributed telescopic rods 6, the telescopic ends of which are all fixedly connected to the upper surface of the feed hopper 2. At this time, the controller 9 can be adjusted to operate the conveyor motor 4, causing the output shaft of the conveyor motor 4 to rotate, which in turn drives the reciprocating screw 33 and the conveyor drive rod 34 to rotate, thereby driving the central conveyor spiral blade 35 to rotate. During the rotation of the reciprocating screw 33, the threaded cylinder 36 reciprocates up and down, which in turn drives the reciprocating moving frame 37 to reciprocate up and down, thereby driving the three side conveyor spiral blades 35 to move up and down inside the feed hopper 2. At this time, the controller 9 can be adjusted to operate the bottom auger 1, allowing the raw materials for the production of thermal insulation mortar to be continuously and quantitatively fed through the feed hopper 7. The raw materials for thermal insulation mortar production are fed into the feeding box 2. At this time, the raw materials for thermal insulation mortar production are gathered in the feeding box 2 and continuously rotated by the conveying spiral blades 35, which transport the raw materials for thermal insulation mortar production to the bottom auger 1. At this time, the bottom auger 1 will continue to transport the raw materials for thermal insulation mortar production. Due to the different characteristics of the raw materials for thermal insulation mortar production, some stubborn polymer powder blocks for thermal insulation mortar production will be broken down into smaller fragments. At this time, the three side conveying spiral blades 35 will rotate themselves during the up-and-down reciprocating movement, which will turn these smaller polymer fragments up and down and further crush them. Then, they will be transported by the central conveying spiral blades 35 to the bottom auger 1 to continue the operation of transporting the raw materials for thermal insulation mortar production.

The drive mechanism 5 also includes a drive motor 51, a multi-groove pulley 52, a transmission wheel 53 and a transmission belt 54.

The input end of the drive motor 51 is electrically connected to the output end of the controller 9. When the raw material conveying device for thermal insulation mortar production is needed, the controller 9 can be adjusted to drive the drive motor 51 to run. The output shaft of the drive motor 51 rotates and drives the multi-groove pulley 52 to rotate, which in turn drives the three transmission wheels 53 to rotate through the transmission belt 54, which in turn drives the three side mixing rods 38 to rotate, which in turn drives the three side conveying spiral blades 35 to rotate.

[0027] The working principle of the raw material conveying device for thermal insulation mortar production provided by this utility model is as follows: When the raw material conveying device for thermal insulation mortar production is needed, the controller 9 can be adjusted to drive the motor 51 to operate. The output shaft of the drive motor 51 rotates, driving the multi-groove pulley 52 to rotate, which in turn drives the three transmission wheels 53 to rotate through the transmission belt 54, thereby driving the three side stirring rods 38 to rotate, and in turn driving the three side conveying spiral blades 35 to rotate. At this time, the controller 9 can be adjusted to drive the conveying motor 4 to operate. The output shaft of the conveying motor 4 rotates, thereby driving the reciprocating screw 33 and the conveying drive rod 34 to rotate, which in turn drives the central conveying spiral blade 35 to rotate. During the rotation of the reciprocating screw 33, the threaded cylinder 36 is driven to move up and down reciprocally, which in turn drives the reciprocating moving frame 37 to move up and down reciprocally, thereby driving the three side conveying spiral blades 35 to move in the feeding box 2. The internal mechanism moves up and down in a reciprocating motion. At this time, the controller 9 can be adjusted, and the bottom auger 1 will operate. The raw materials for thermal insulation mortar production can be continuously and quantitatively poured into the feeding box 2 through the feeding hopper 7. The raw materials for thermal insulation mortar production gather in the feeding box 2 and are then continuously transported to the interior of the bottom auger 1 by the continuous rotation of the conveying screw 35. The bottom auger 1 will continuously transport the raw materials for thermal insulation mortar production. Due to the different characteristics of the raw materials for thermal insulation mortar production, some stubborn polymer powder blocks will be broken down into smaller fragments. At this time, the three side conveying screws 35 will rotate themselves during the up and down reciprocating motion, which will turn these smaller polymer fragments up and down and further crush them. Then, they will be transported to the interior of the bottom auger 1 by the central conveying screw 35, and the thermal insulation mortar production raw material transportation operation will continue.

[0028] It is worth noting that the core chip of the controller 9 disclosed in the above embodiments is a PLC microcontroller, specifically the STM32.
