Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, and in particular to low-cost waste metering equipment. Background Technology

[0002] Waste disposal refers to the process of removing, rendering harmless, and rationally utilizing solid waste. Its core objectives are to achieve harmlessness, resource recovery, and waste reduction. Measuring equipment is used to accurately measure the quantity and weight of waste and help managers accurately grasp the actual situation of waste disposal.

[0003] In the waste management process, accurate measurement of waste weight is of great significance for waste management cost accounting, waste management volume statistics, and waste management planning. Traditional waste metering equipment lacks convenient auxiliary structures, is prone to spillage during waste disposal, and has an unfriendly operating interface, making it difficult to quickly and accurately control the equipment and meet the needs of efficient metering. Therefore, we propose a low-cost waste metering device to solve the above problems. Utility Model Content

[0025] Please see Figure 1-5In this utility model, a low-cost waste metering device includes a support platform 1, a display device 3 installed at the top of the support platform 1, a weighing component 2 installed on the upper surface of the support platform 1, a bottom protective frame 4 installed on the upper surface of the weighing component 2, a sliding cavity 5 opened inside the bottom protective frame 4, a movable protective frame 6 slidably connected inside the sliding cavity 5, a square box 8 fixedly connected to the outer surface of the support platform 1, a motor 9 fixedly connected to the inner bottom wall of the square box 8, a lead screw 10 fixedly connected to the output end of the motor 9, a threaded ring 11 threadedly connected to the outer surface of the lead screw 10, and two transmission square plates 12 fixedly connected to the outer surface of the threaded ring 11. Each transmission square plate 12 has one The weighing component 2 penetrates the square box 8 and is fixedly connected to the upper surface of the moving guard frame 6. The weighing component 2 realizes the measurement of garbage weight, and the display device 3 displays the data in real time. The display device 3 has a built-in data processing module and adopts a simple circuit design based on a single-chip microcomputer. The single-chip microcomputer is a low-priced and stable model on the market, such as the STC89C52 single-chip microcomputer. It also has an external low-cost digital tube display screen. The digital tube has the advantages of clear display, low price and simple driving circuit. The motor 9, lead screw 10, screw ring 11 and transmission square plate 12 form a lifting mechanism, which drives the moving guard frame 6 to adjust the protection height to meet the weighing and protection needs of garbage of different heights.

[0026] A square plate 17 is fixedly connected to the inner wall of the square box 8. Two long sliding columns 13 are fixedly connected to the upper surface of the square plate 17. Each long sliding column 13 is slidably connected to the transmission square plate 12. The long sliding column 13 and the transmission square plate 12 are slidably connected to provide guidance and support for the movement of the transmission square plate 12, ensuring that the moving guard frame 6 runs smoothly during the lifting process, avoiding tilting and jamming, and ensuring stable and reliable protection function. Two square openings 14 are opened on the outer surface of the square box 8, and the square openings 14 are slidably connected to the transmission square plate 12. Each square opening 14 is equipped with a telescopic cloth 15. The square openings 14 provide a moving channel for the transmission square plate 12. The telescopic cloth 15 covers the square openings 14, which can not only ensure the free sliding of the transmission square plate 12, but also prevent dust and debris from entering the interior of the square box 8, protecting the transmission components such as the motor 9 and the lead screw 10, and extending the service life of the equipment. Multiple support feet 18 are fixedly connected to the bottom surface of the support platform 1. The support feet 18 increase the contact area between the equipment and the ground and improve the stability of the equipment.

[0027] Two side handles 7 are fixedly connected to the outer surface of the support platform 1. The side handles 7 provide leverage points for the equipment, facilitating the handling and movement of equipment by staff. The weighing assembly 2 includes multiple weighing sensors 201 fixedly connected to the upper surface of the support platform 1. The tops of the multiple weighing sensors 201 are all fixedly connected to a weighing pan 202. The upper surface of the weighing pan 202 is fixedly connected to the bottom surface of the bottom protective frame 4. The multiple weighing sensors 201 jointly support the weighing pan 202, distributing pressure and improving the accuracy and stability of weighing. The weighing pan 202 provides a platform for placing waste and is fixedly connected to the bottom protective frame 4, forming a regular weighing space for convenient waste weighing. Furthermore, during weighing, the bottom protective frame... The frame 4 will move slightly downwards, and it is slidably connected to the moving guard frame 6 through the sliding cavity 5. Therefore, it will not affect normal weighing or its normal up-and-down movement. The weighing sensor 201 is a low-cost resistance strain gauge weighing sensor 201. This sensor has the advantages of simple structure, low price and stable performance, and can meet the weighing accuracy requirements of small-scale waste disposal scenarios. The back of the square box 8 is fixedly installed with an operation button 16. The operation button 16 is electrically connected to the motor 9 through a wire. The operator can control the start, stop and direction of the motor 9 through the operation button 16, and thus control the lifting and lowering of the moving guard frame 6. The operation is simple and intuitive.

[0028] The working principle of this utility model is as follows:

[0029] When using this device, place the garbage on the weighing pan 202. If the garbage is piled up high, press the operation button 16 to start the motor 9. The motor 9 drives the lead screw 10 to rotate, which in turn drives the screw ring 11 and the transmission square plate 12 to rise under the action of the screw thread. The transmission square plate 12 causes the moving guard frame 6 to rise in the sliding cavity 5 to surround the garbage and prevent it from tipping over. The weighing sensor 201 quickly senses the weight and transmits the weight data to the display device 3 for display. The whole process is convenient to operate, accurate in measurement, and meets the weighing and protection needs of garbage of different heights.
