[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1-5 A dual-gate coarse and fine feeding device includes a support box 1, a feeding trough 2, and a weighing scale 3. The feeding trough 2 is installed on one side of the top of the support box 1. The support box 1 can be installed at an angle toward the discharge pipe 215. The material is fed into the feeding trough 2 for conveying and feeding. The weighing scale 3 is installed on the other side of the top of the support box 1. The weighing scale 3 can accurately measure the weight of the material, so that the material can be accurately conveyed. The top of the support box 1 is provided with a feeding structure and a discharge structure.

[0024] Specifically, the feeding structure includes a drive motor 111, a screw rod 112, a screw rod 113, a connecting cylinder 114, a discharge box 115, and a controller 116. The controller 116 and the two sets of drive motors 111 are installed on the outside of the feed trough 2. One end of the screw rod 112 and the screw rod 113 are fixedly connected to the output end of the drive motor 111. The diameter of the screw rod 112 is smaller than the diameter of the screw rod 113. The two ends of the connecting cylinder 114 are fixedly connected to the feed trough 2 and the discharge box 115 by screws. The two sets of connecting cylinders 114 are located on the outside of the screw rod 112 and the screw rod 113, respectively.

[0025] Through the above technical solution, when the material is put into the feed trough 2, the drive motor 111 is started. The drive motor 111 can drive the screw rod 112 and the screw rod 113 to rotate. The screw rod 112 and the screw rod 113 convey the material through the connecting cylinder 114 and the discharge box 115. When the screw rod 113 rotates, it will convey a large amount of material. When the material is conveyed to a certain amount, the drive motor 111 drives the screw rod 112 to rotate. When the screw rod 112 rotates, it conveys a small amount of material. Thus, the double-gate feeding device can accurately convey the material without delaying the discharge time, thereby improving the conveying speed and accuracy of the double-gate feeding device.

[0026] Specifically, the discharge structure includes a storage box 211, a second drive motor 212, a connecting rod 213, a scraper 214, a discharge pipe 215, and an automatic valve 216. The storage box 211 is installed on the top of the weighing scale 3. The second drive motor 212 is installed in the middle of the top of the storage box 211. One end of the connecting rod 213 is fixedly connected to the output end of the second drive motor 212. One end of the scraper 214 is fixedly connected to the outer surface of the connecting rod 213 by screws. The other end of the scraper 214 is slidably connected to the inner side of the storage box 211. One end of the discharge pipe 215 is connected to the storage box 211. The automatic valve 216 is installed at the other end of the discharge pipe 215. The connecting rod 213 is connected to the storage box 211 through a bearing. The outer side of the scraper 214 is an arc-shaped surface. A square slot is opened at the top of the storage box 211 corresponding to the position of the discharge box 215.

[0027] Through the above technical solution, when the material is put into the storage bin 211, the weighing scale 3 can accurately measure the material inside the storage bin 211. When the weighing scale 3 weighs close to the preset quantitative amount, the weighing scale 3 starts the controller 116 through the circuit. The controller 116 shuts down the drive motor 111 connected to the second screw rod 113 and starts the drive motor 111 connected to the first screw rod 112. When the screw rod 112 rotates, it can slowly convey the material. After the material is conveyed to the predetermined amount, the second drive motor 212 is started. The second drive motor 212 drives the connecting rod 213 to rotate. When the connecting rod 213 rotates, it drives the scraper 214 to rotate. When the scraper 214 rotates, it can push the material into the discharge pipe 215. When the automatic valve 216 is started, the material can be discharged. The double gate feeding device can accurately feed the material quantitatively, thereby improving the feeding accuracy of the double gate feeding device.

[0028] When in use, the screw rod 113 rotates to convey a large amount of material. When the material is conveyed to a certain amount, the drive motor 111 drives the screw rod 112 to rotate. The screw rod 112 then conveys a small amount of material, thus enabling the double-gate feeding equipment to convey material accurately without delaying the discharge time, thereby improving the conveying speed and accuracy of the double-gate feeding equipment.
