[0001] The utility model relates to the technical field of fly ash weighing scales, in particular to a fly ash weighing scale which is convenient for unloading. Background Art

[0002] Fly ash is a lightweight, dry powder with excellent fluidity. Accurately measuring and controlling the amount of fly ash added has been a challenge for cement plants for many years.

[0003] The existing fly ash metering scales used in cement production are mostly noisy when in use, causing great noise pollution to the surrounding environment. The existing fly ash metering scales used in cement production are mostly welded together, which is not convenient for disassembly and maintenance, and is relatively troublesome to repair. The existing fly ash metering scales used in cement production are mostly unable to adjust the height of the support legs, and the parallelism is poor, which is easily affected by the terrain and causes the device to shake.

[0004] For example, a fly ash weighing scale for cement production disclosed in Chinese patent CN212513256U is provided. By arranging a first slot, a first block, a first fixing nut, a first sound insulation board, a honeycomb sound insulation board, a protective box, a second slot, a second block, a second fixing nut and a screw block, when in use, the parts cooperate and interact with each other, which is beneficial to reducing the noise generated when the device is in use, and reducing the noise pollution to the surrounding environment, facilitating the installation and disassembly of the device, and facilitating the repair and replacement of damaged parts. By arranging a first support rod, an adjusting nut, an adjusting hole, a second support rod and a suction cup, when in use, the parts cooperate and interact with each other, which is beneficial to adjusting the height of the support feet, which is beneficial to adjusting the levelness of the device, improving the stability of the device, and reducing the shaking of the device due to the influence of the terrain.

[0005] However, after the fly ash is weighed by the weighing scale, it is not convenient to take out the weighed fly ash, resulting in inconvenience in unloading the fly ash.

[0006] For this reason we urgently need to provide a kind of fly ash weighing scale that is convenient to unloading. Utility Model Content

[0007] The purpose of the utility model is to provide a fly ash weighing scale that is convenient for unloading, so as to solve the problem that after the weighing scale proposed in the above background technology weighs the fly ash, it is not convenient to take out the weighed fly ash, resulting in inconvenience in unloading the fly ash.

[0015] A further improvement is that the inner front end of the cylinder is provided with insertion holes at equal distances in the vertical direction, so that the second spring rebounds and pushes the insertion rod forward, causing the insertion rod to move to the insertion hole at the corresponding position of the inner front end of the cylinder, so that the overall length of the support rod and the cylinder can be adjusted to the required length and then re-fixed.

[0016] In summary, the present application discloses a fly ash weighing scale that is convenient for unloading.

[0017] According to the technical solution, after the fly ash is poured from the feed hopper into the transmission cylinder, the motor is started and its output shaft rotates to drive the auger located inside the transmission cylinder to rotate, so that the fly ash in the transmission cylinder is transmitted to the right and continuously falls into the weighing box at the right end until the weighing device weighs the fly ash in the weighing box to the required weight. The bending plate is then pulled up until the right end of the bending plate is no longer to the right of the closing plate, and the closing plate is pulled to the right to rotate the closing plate away from the metering box. The weighing box in the metering box is then taken out to complete the unloading of the fly ash.

[0018] Furthermore, after pushing the insertion rod to the inner side of the circular groove by pushing it backward, the support rod is then slid along the inner side of the cylinder until the overall length of the cylinder and the support rod is adjusted to the required length. The second spring rebounds and pushes the insertion rod forward, so that the insertion rod moves to the socket at the corresponding position at the front end of the cylinder. The overall length of the support rod and the cylinder can be adjusted to the required length and then re-fixed, so that the entire device can be placed on the ground with poor parallelism.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] Example 1:

[0028] A fly ash weighing scale for facilitating unloading comprises a workbench 1 and a connecting rod 2, wherein the connecting rod 2 is fixedly connected to the left and right ends of the upper side of the workbench 1, and the upper and lower ends of the workbench 1 are connected with a metering mechanism, which comprises a metering unit and an adjusting unit, wherein the metering unit is arranged at the upper end of the connecting rod 2, and the adjusting unit is arranged at the lower end of the workbench 1.

[0029] The metering unit includes a transmission cylinder 301, a feed hopper 302, a motor 303, an auger 304, a metering box 305, a sealing plate 306, a weighing device 307, a weighing box 308, a round rod 309, a round plate 310, a first spring 311, and a bent plate 312. The transmission cylinder 301 is fixedly connected to the upper end of the connecting rod 2 at the upper left end of the workbench 1. The feed hopper 302 is fixedly connected to the left side of the upper end of the transmission cylinder 301. The motor 303 is fixedly connected to the left middle position of the transmission cylinder 301. The auger 304 is fixedly connected to the right end of the output shaft of the motor 303. The inner side of the transmission cylinder 301 is slidably connected to the outer side of the auger 304. Therefore, when the motor 303 is started and its output shaft rotates, the auger 304 located inside the transmission cylinder 301 rotates, and the fly ash in the transmission cylinder 301 is transported.

[0030] The metering box 305 is fixedly connected to the upper end of the connecting rod 2 at the upper right end of the workbench 1. The sealing plate 306 is hinged to the right end of the metering box 305. The weighing device 307 is fixedly connected to the inner bottom end of the metering box 305. The weighing box 308 is placed on the upper end of the weighing device 307. The round rod 309 is fixedly connected to the middle position of the upper right end of the metering box 305. The circular plate 310 is fixedly connected to the upper end of the round rod 309. The first spring 311 is fixedly connected to the lower side of the circular plate 310. The bent plate 312 is fixedly connected to the lower end of the first spring 311. A limiting hole is defined at the middle position of the inner left end of the bent plate 312. The outer side of the round rod 309 is slidably connected to the inner side of the limiting hole. Therefore, when the first spring 311 is activated, it can drive the bent plate 312 to slide along the outer side of the round rod 309, thereby limiting the movement of the bent plate 312.

[0031] The inner right end of the bent plate 312 abuts against the right side of the upper end of the sealing plate 306, and the right end of the transmission cylinder 301 is fixedly connected to the left end of the sealing plate 306. Therefore, after the sealing plate 306 is rotated to the right side of the metering box 305, the first spring 311 rebounds and pushes the bent plate 312 downward, causing the right end of the bent plate 312 to move to the right of the upper end of the sealing plate 306, and the sealing plate 306 can be fixed to the right side of the metering box 305, thereby sealing the metering box 305.

[0032] Example 2:

[0033] Based on the first embodiment, the adjustment unit includes a cylinder 401, a support rod 402, a second spring 403, and an insertion rod 404. Cylinder 401 is fixedly connected to the four corners of the lower side of workbench 1. Support rod 402 is slidably connected to the inner side of cylinder 401. Second spring 403 is connected to the inner upper end of support rod 402, and insertion rod 404 is fixedly connected to the front end of second spring 403. A circular groove is formed at the front end of the inner upper end of support rod 402. The rear end of second spring 403 is fixedly connected to the inner rear end of the circular groove, and the outer side of insertion rod 404 is slidably connected to the inner side of the circular groove. Therefore, when second spring 403 is activated, it can drive insertion rod 404 to slide along the inner side of the circular groove, thereby limiting the movement of insertion rod 404.

[0034] Insertion holes are formed at equal intervals along the front end of the cylinder 401. After the support rod 402 is slid to the corresponding position inside the cylinder 401, the second spring 403 rebounds and pushes the insertion rod 404 forward, causing the insertion rod 404 to move into the insertion hole at the corresponding position inside the front end of the cylinder 401. This allows the overall length of the support rod 402 and cylinder 401 to be adjusted to the desired length and then re-secured.

[0035] Working principle: When in use, first pour the fly ash from the feed hopper 302 into the transmission cylinder 301, then start the motor 303 and its output shaft rotates to drive the auger 304 located on the inner side of the transmission cylinder 301 to rotate, and transmit the fly ash in the transmission cylinder 301 to the right, and continuously fall into the weighing box 308 at the right end, until the weighing device 307 weighs the fly ash in the weighing box 308 to the required weight, pull up the bending plate 312 until the right end of the bending plate 312 is no longer to the right of the sealing plate 306, pull the sealing plate 306 to the right to drive the sealing plate 306 to rotate away from the metering box 305, and then take out the weighing box 308 in the metering box 305 to use the fly ash therein.
