Description

Technical Field

[0001] This utility model relates to the field of batching equipment technology, specifically to a high-efficiency mixing device for batching scales. Background Technology

[0002] A batching scale is a weighing instrument used to measure the proportions of several substances in a weighed product. It has a wide range of applications, suitable for measuring both multiple materials and a single material. In the production and processing of compound fertilizers, to ensure fertilizer quality, the raw materials and additives need to be precisely proportioned before mixing, thus requiring the use of a batching scale.

[0003] A search revealed patent application CN201621439855.5, which discloses a batching device for an electronic batching scale, particularly relating to the field of feed production and processing technology. This batching device for an electronic batching scale includes: a feed hopper, a weight sensor, a support, a discharge plate I, a discharge storage hopper, a discharge trolley, a slide rail, and a discharge plate II. The feed hopper is fixed to the support, and a weight sensor is installed between the feed hopper and the support. The discharge plate I is located at the bottom of the feed hopper, and a discharge storage hopper is located below the discharge plate I. The discharge plate II is located at the bottom of the discharge storage hopper. The discharge trolley is mounted on the slide rail, and both ends of the slide rail are connected to the support. The batching device for an electronic batching scale provided by this utility model features accurate batching and a simple structure.

[0004] However, this patent has its shortcomings. The unloading hopper in the batching device of this electronic batching scale lacks a quantitative conveying component. When too much raw material is fed into the unloading hopper at once, it can easily cause blockage and affect the normal feeding operation. At the same time, this patent does not have a mixing mechanism. After each batching is completed, the staff still needs to pour the batched raw materials and additives from the unloading trolley into other mixing equipment for stirring and mixing. The operation steps are relatively cumbersome and can easily affect the processing efficiency.

[0005] To address this, we propose a high-efficiency mixing device for batching scales. Utility Model Content

Slide plates 6 are fixedly installed at both ends of the batching hopper 2. The two slide plates 6 are slidably connected to the corresponding mounting brackets 3, and pressure rods 7 are fixedly installed at the bottom of the two slide plates 6. Gravity sensors 8 are fixedly installed at the bottom of the mixing tank 1, which is located at the top of the two mounting brackets 3. The bottom ends of the two pressure rods 7 abut against the top ends of the corresponding gravity sensors 8. A transmission rod 22 is rotatably connected to the bottom of the batching hopper 2. 22 is fixedly fitted with a conveying impeller 5 on the outside. The mixing tank 1 is arranged from top to bottom with a mixing tank 11 and a drive tank 12. The drive tank 12 is rotatably connected with a drive gear 20. Multiple driven gears 19 are meshed on the outside of the drive gear 20. The top of each of the multiple driven gears 19 is fixedly mounted with a sub-shaft 15. The top of the drive gear 20 is fixedly mounted with a main shaft 16. The tops of the main shaft 16 and the multiple sub-shafts 15 extend into the mixing tank 11. Multiple first stirring blades 17 are fixedly mounted on the outside of the main shaft 16. Multiple second stirring blades 18 are fixedly mounted on the outside of each sub-shaft 15.

[0023] A motor 14 is fixedly installed at the front end of the mixing hopper 2. The output end of the motor 14 is fixedly installed on the transmission rod 22. The rotation of the transmission rod 22 driven by the motor 14 is beneficial to the use of this equipment. Multiple first stirring blades 17 and second stirring blades 18 are arranged alternately. This design is beneficial to the use of this equipment. A connecting pipe 10 is fixedly installed at the bottom end of the mixing hopper 2. A guide pipe 9 is fixedly installed at the top of the mixing tank 1 directly below the mixing hopper 2. The connecting pipe 10 is slidably connected in the guide pipe 9. This design is beneficial to the use of this equipment. A discharge pipe 13 is fixedly installed on the left side of the mixing tank 1, corresponding to the mixing tank 11. A solenoid valve is fixedly installed in the discharge pipe 13. The mixed raw materials are easily discharged through the discharge pipe 13. A PLC controller 4 is fixedly installed at the front end of the mixing tank 1. The PLC controller 4 is equipped with a display screen. The PLC controller 4 is used to control the operation of this equipment. A motor 21 is fixedly installed at the bottom end of the mixing tank 1.

[0024] Working Principle: During use, the required proportions of raw materials or additives are poured into the mixing hopper 2. The weight of the raw materials or additives causes the two sliding plates 6 and pressure rod 7 to press down. The gravity sensor 8 detects the weight of the raw materials or additives based on the pressure of the pressure rod 7 and transmits the data to the display screen on the PLC controller 4. When the required proportions are reached, the operator stops feeding and opens the discharge switch. At this time, the motor 14 drives the transmission rod 22 and the conveyor impeller 5 to rotate, causing the raw materials or additives to enter the mixing tank 1 in batches. Using the above principle, the raw materials and additives are precisely proportioned. When the mixing switch is turned on, the motor 21 drives the drive gear 20, driven gear 19, main shaft 16, sub-shaft 15, first stirring blade 17, and second stirring blade 18 to rotate, thus creating different directions of stirring for the raw materials and additives in the mixing tank 11. This type of batching scale high-efficiency mixing device is easy to use. Through the above components, the raw materials and additives can be quickly and accurately proportioned and transported to the mixing tank 1 in batches, avoiding blockage in the guide pipe 9. At the same time, it can directly and quickly stir and mix the raw materials and additives after proportioning, reducing the number of operation steps for workers and further improving processing efficiency.
