[0002] There will be food waste in communities, hotels, commercial complexes, restaurants and other places. After the implementation of garbage classification, food waste is generally poured into special food waste bins, and then the food waste bins are centrally processed. In particular, the amount of food waste generated by restaurants and communities is large. During the initial processing, it is poured into the food waste bin and cannot be further processed, resulting in a large amount of space being occupied in the food waste bin. In the later processing, there are food residues, water and oil solutions in the food waste bin, resulting in a lot of extra manpower and material resources during the transportation process.

[0003] In the prior art, kitchen waste is collected and processed in a centralized manner. However, during the processing, since the kitchen waste is not processed in a centralized and quantitative manner, the amount of kitchen waste processed cannot be rationally controlled. During processing, the weight of the kitchen waste is sometimes large and sometimes small. As a result, during the processing, the kitchen waste equipment may be overloaded or idle, resulting in excessive equipment loss and waste of electricity. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1

[0026] The present invention provides a weighing device for real-time detection of food waste collection system, see Figure 1-Figure 3 , including a workbench 100, on which a kitchen waste temporary storage box 200 is arranged, and a kitchen waste inlet 210 is formed above the kitchen waste temporary storage box 200; a detection mechanism 300 for real-time detection of the weight of the kitchen waste in the kitchen waste temporary storage box 200 and a weighing mechanism 400 for weighing are arranged on the workbench 100; a kitchen waste discharge port 220 is opened at the bottom of the kitchen waste temporary storage box 200, and a control mechanism 500 for closing or opening the kitchen waste discharge port 220 is arranged on the kitchen waste temporary storage box 200. During operation, the food waste discharge port 220 is closed through the control mechanism 500. When the food waste is put into the food waste temporary storage box 200, the food waste entering the food waste temporary storage box 200 is weighed in real time through the set detection mechanism 300 and the weighing mechanism 400. When the weight reaches the set weight, the food waste discharge port 220 is opened through the control mechanism 500, and the food waste is discharged from the food waste discharge port 220 to the next processing equipment for centralized processing.

[0027] An equipment installation cavity 110 is formed in the middle of the workbench 100, and the kitchen waste temporary storage box 200 is located in the equipment installation cavity 110. A plurality of guide posts 120 are arranged at intervals in the vertical direction on the workbench 100 and in the equipment installation cavity 110. The guide posts 120 are located on the circumferential side of the kitchen waste temporary storage box 200. A positioning ring 230 is fixed on the outer side of the kitchen waste temporary storage box 200. The positioning ring 230 is provided with a sliding hole, and the guide posts 120 pass through the sliding hole. Through this arrangement, the kitchen waste temporary storage box 200 is in an active state in the vertical direction. Through the set guide posts 120, the kitchen waste temporary storage box 200 can be limited and weighed conveniently.

[0028] The detection mechanism 300 includes a first limiting ring 310 and a second limiting ring 320 which are arranged in the equipment installation cavity 110. The first limiting ring 310 and the second limiting ring 320 are both located on the outside of all guide columns 120 and on the lower side of the positioning ring 230. The inner diameters of the first limiting ring 310 and the second limiting ring 320 are smaller than the outer diameter of the positioning ring 230.

[0029] The second limit ring 320 is located at the lower side of the first limit ring 310, and a compression spring 330 is fixedly connected between the first limit ring 310 and the second limit ring 320; the inner wall of the equipment installation cavity 110 is provided with a detection groove 130 in the vertical direction, and the two ends of the detection groove 130 are closed in the length direction, and multiple detection grooves 130 are arranged at intervals along the circumferential direction. A pressure sensor 340 is fixedly installed at the bottom of the detection groove 130; the circumferential sides of the first limit ring 310 and the second limit ring are spaced apart to set limit blocks 350, and the limit blocks 350 are embedded in the detection groove 130. Among them, the limit blocks 350 are detachably connected to the first limit ring 310 and the second limit ring 320, and can be specifically fixedly connected by bolts.

[0030] Under the action of the compression spring 330, the first limit ring 310 has upward elastic potential energy, and the upper end of the detection slot 130 is a closed end, which can limit the limit block 350. The upper end of the detection slot 130 is the maximum height of the first limit ring 310 to lift the kitchen waste temporary storage box 200. When the garbage is put into the kitchen waste temporary storage box 200, when the weight of the internal kitchen waste increases, the pressure value received by the pressure sensor 340 gradually increases. The weight of the kitchen waste in the kitchen waste temporary storage box 200 is judged by the pressure value detected by the pressure sensor 340 at this position.

[0031] When the first limit ring 310 abuts against the positioning ring 230, the pressure sensor 340 obtains the gravity value of the kitchen waste temporary storage box 200. When the gravity value detected by the pressure sensor 340 reaches the preset value, the load-bearing mechanism abuts against the positioning ring 230, and the first limit ring 310 is separated from the positioning ring 230. Through this setting, the weighing mechanism 400 can be prevented from continuously weighing. At the same time, the two can be coordinated for calibration to achieve accurate processing of kitchen waste.

[0032] The weighing mechanism 400 includes a weighing scale 410 fixed to the bottom of the equipment installation cavity 110, a support plate 420 is fixed on the upper side of the weighing scale, a first electric push rod 430 is fixedly installed on the upper side of the support plate 420, the first electric push rod 430 is located between adjacent guide columns 120, a positioning sleeve 440 is integrally formed on the lower side of the positioning ring 230, and the piston end of the first electric push rod 430 is slidably connected in the positioning sleeve 440. When the gravity value detected by the pressure sensor 340 reaches the preset value, when the first electric push rod 430 is extended, the piston end can abut against the bottom end of the positioning sleeve 440, and control the positioning ring 230 to disengage from the first limit ring 310. Specifically, the first electric push rod 430 controls the positioning ring 230 to move upward until the positioning ring 230 is disengaged from the first limit ring 310.

[0033] A funnel-shaped internal discharge hopper 221 is formed on the inner side of the bottom of the kitchen waste temporary storage box 200, a kitchen waste temporary storage cavity is formed above the internal discharge hopper 221, and an equipment installation cavity 110 is formed between the internal discharge hopper 221 and the kitchen waste discharge port 220 for installing the control mechanism 500.

[0034] The control mechanism 500 includes a guide rail 510 fixed to the outer side of the internal discharge hopper 221, and two groups of guide rails 510 are arranged in parallel on both sides of the internal discharge hopper 221; a baffle 520 is slidably arranged between the two groups of slide rails, and a second electric push rod 530 is arranged on the upper side of the guide rail 510 to drive the baffle 520 to slide to open or close the internal discharge hopper 221.

[0035] Better yet, a rubber layer is provided on one side of the baffle 520 close to the internal discharge hopper 221, and the rubber layer abuts against the internal discharge hopper 221. When the internal discharge hopper 221 is closed, the internal discharge hopper 221 can be closed to avoid water leakage and the like.

[0036] A discharge pipe is installed on the outside of the kitchen waste discharge port, through which the kitchen waste is transported to the next output device for centralized processing.

[0037] The kitchen waste inlet 210 is funnel-shaped, the upper end area of ​​the kitchen waste inlet 210 is larger, and the lower end area of ​​the kitchen waste inlet 210 is smaller.
