Technical Field
[0001] This utility model relates to the field of feeding scale technology, specifically to an anti-clogging assembled feeding scale. Background Technology
[0002] A feed scale is a weighing device used to measure and control the amount of material fed into the system. It is commonly used in industrial production. It uses load cells to measure the weight of the material flowing through or being loaded in real time, ensuring that the material is fed accurately according to the set weight or speed.
[0003] For example, Chinese patent CN209995130U discloses a feeding weighing device and a feeding weighing system. The feeding weighing device includes a feed hopper with a baffle device at the bottom. When the baffle device is fixed at a first position corresponding to the feed outlet of the hopper, it fully opens the feed outlet; when fixed at a second position corresponding to the feed outlet, it fully closes the feed outlet. A hanging scale is electrically connected to the baffle device and is used for quantitative control of the feed hopper. The baffle device moves between the first and second positions via the hanging scale. By setting a baffle device in the feed hopper and cooperating with the hanging scale for quantitative weighing control, livestock farmers can better control the feeding amount, ensure feeding effectiveness, improve livestock management, and significantly enhance the scientific and rational nature of livestock feeding. This is beneficial for accurately calculating the feed conversion ratio and controlling livestock costs.
[0004] In the operation of existing feeding scales, when the material distribution is uneven during the feeding process, the center of gravity of the material on the weighing platform will shift. This shift in the center of gravity will generate asymmetrical forces on the weighing sensor, thereby affecting the weighing accuracy and stability of the system. Utility Model Content
[0005] The purpose of this invention is to provide an anti-clogging assembled feeding scale to solve the problem in the background art where uneven material distribution during the feeding process causes the center of gravity of the material on the weighing platform to shift.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-clogging assembled feed scale, comprising a horizontally placed base, a weighing platform mounted on the top of the base, and a support plate mounted on the top of the weighing platform; The support plate is designed with an arched structure. Pressure sensors are fixedly connected to the weighing platform at the four corners of the bottom of the support plate. The top two sides of the support plate are provided with symmetrically distributed guide rails. A motion platform is slidably connected to the top of the support plate. The bottom two sides of the motion platform are fixedly connected to the guide rails. A threaded sleeve is fixedly connected to the middle of the bottom of the motion platform. A lead screw is rotatably connected to the middle of the top of the support plate through a bearing seat. The lead screw is driven by a motor and is threaded to the inside of the threaded sleeve. The pressure sensors and the motor that drives the lead screw to rotate are electrically connected.
[0007] Preferably, the top of the support plate is fixedly connected to a discharge pipe by a bracket, the discharge pipe is suspended in the middle of the top of the support plate, the top of the discharge pipe is provided with a feeding groove, and the inner side of the feeding groove is provided with symmetrically distributed sliding grooves.
[0008] Preferably, two transport screws are fixedly connected inside the discharge pipe, one end of each transport screw extends to the outside of the discharge pipe, and a gear is fixedly connected to the end of each transport screw extending to the outside of the discharge pipe.
[0009] Preferably, the two gears located at the end of the transport screw mesh with each other and are driven by a motor. The end of the discharge pipe away from the gears is an open structure forming a discharge port, and a protective sleeve is fixedly connected to its outer side.
[0010] Preferably, the top center of the motion table is provided with a guide groove, and the discharge pipe is slidably connected inside the guide groove.
[0011] Preferably, a feeding hopper is fixedly connected to the top of the guide groove, and a discharge port is provided in the middle of the bottom of the feeding hopper, with the discharge port aligned with the feeding groove.
[0012] Preferably, a stirring crank driven by a motor is rotatably connected inside the feeding hopper, and a cover strip is fixedly connected to both ends of the feeding hopper outlet, with the cover strip slidably connected inside the chute.
[0013] Compared with the prior art, the beneficial effects of this utility model are: This anti-clogging assembled feeder uses four pressure sensors symmetrically distributed at the four corners of an arched support plate to monitor the pressure difference between the two ends of the support plate in real time, directly capturing the material's center of gravity shift. The transmission between the lead screw and the threaded sleeve, in conjunction with the real-time response of the motor, drives the motion table to slide along the guide rail, dynamically correcting the position of the motion table to balance the load. The arched support plate concentrates the top load to the pressure sensors at the four corners, avoiding interference from the intermediate structure and improving detection sensitivity.
[0014] The symmetrically arranged conveyor screws inside the discharge pipe rotate synchronously through gear meshing, pushing the material in both directions to avoid one-sided accumulation. The cover strips on both sides of the discharge port of the feeding hopper slide and cooperate with the feed chute chute, always covering the feed chute opening when the moving table moves, maintaining the seal. The stirring crank in the feeding hopper rotates continuously to break up material clumps, preventing blockage from the source. The drive motor of the conveyor screw is linked with the pressure sensor signal, and automatically stops when the unloading reaches the set weight threshold. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1: Please refer to Figure 1 and Figure 2The present invention provides the following technical solution: a clog-resistant assembled feeding scale, comprising a horizontally placed base 1, a weighing platform 2 mounted on the top of the base 1, and a support plate 3 mounted on the top of the weighing platform 2; the support plate 3 is designed with an arched structure, and pressure sensors 4 are fixedly connected between the four corners of the bottom of the support plate 3 and the weighing platform 2; symmetrically distributed guide rails are provided on both sides of the top of the support plate 3; a moving platform 10 is slidably connected to the top of the support plate 3; the bottom sides of the moving platform 10 are fixedly connected to the guide rails; a threaded sleeve 11 is fixedly connected to the middle of the bottom of the moving platform 10; a lead screw 12 is rotatably connected to the middle of the top of the support plate 3 through a bearing seat; the lead screw 12 is driven by a motor, and the lead screw 12 is threadedly connected to the inside of the threaded sleeve 11; the pressure sensors 4 and the motor driving the lead screw 12 to rotate are electrically connected.
[0019] During the operation of the device, materials are added to the interior through the feeding hopper 14; after being guided into the system by the feeding hopper 14, the materials move along the transport path and are finally discharged from the discharge port inside the protective sleeve 9; the end outlets of the protective sleeve 9 and the discharge pipe 5 extend to the outside of the base 1, so that the materials can be smoothly transported to the external container; at the same time, the feeding hopper 14 can be connected to the external container to achieve continuous feeding; however, during the feeding process, the materials may be unevenly distributed inside the container, causing the center of gravity to shift; since all the materials and equipment weights carried on the top of the support plate 3 are transmitted to the weighing platform 2 through four pressure sensors 4, the pressure sensors 4 are fixedly connected between the four corners of the bottom of the support plate 3 and the weighing platform 2; when the center of gravity shifts, the uneven load on the top of the support plate 3 will cause the two sets of pressure sensors 4 located at both ends of the weighing platform 2 to bear different pressure values.
[0020] Pressure sensor 4 sends a signal to control the motor driving lead screw 12 to rotate by comparing the pressure difference at both ends in real time. The lead screw 12 is driven by the motor and rotatably connected to the top center of the support plate 3 through a bearing seat, and its threaded part is fitted into the threaded sleeve 11. When the motor drives the lead screw 12 to rotate, it causes the threaded sleeve 11 to slide on the outside, thereby pushing the motion table 10 to move along the guide rail at the top of the support plate 3. The motion table 10 is fixedly connected to the guide rail and the threaded sleeve 11, and its position change can adjust the overall center of gravity distribution at the top of the support plate 3. By moving the motion table 10 and optimizing its placement on the top of the weighing platform 2, the system gradually reduces the pressure difference at both ends of pressure sensor 4, keeping it within a predetermined range and preventing imbalance caused by center of gravity shift.
[0021] Example 2: Based on Example 1, please refer to... Figure 3 - Figure 6The following structure is also disclosed: a discharge pipe 5 is fixedly connected to the top of the support plate 3 via a bracket. The discharge pipe 5 is suspended in the middle of the top of the support plate 3. A feed groove 6 is provided at the top of the discharge pipe 5, and symmetrically distributed sliding grooves 7 are provided on the inner side of the feed groove 6. Two transport screws 8 are fixedly connected inside the discharge pipe 5. One end of the two transport screws 8 extends to the outside of the discharge pipe 5, and a gear is fixedly connected to the end of the two transport screws 8 extending to the outside of the discharge pipe 5. The two gears located at the ends of the transport screws 8 mesh with each other, and the gears are driven by a motor. 5. The end away from the gear is an open structure forming a discharge port, and a protective sleeve 9 is fixedly connected to its outer side; the top of the motion table 10 is provided with a guide groove 13 in the middle, and the discharge pipe 5 is slidably connected to the inside of the guide groove 13; the top of the guide groove 13 is fixedly connected with a feeding hopper 14, and the bottom of the feeding hopper 14 is provided with a discharge port in the middle, which is aligned with the feeding groove 6; the inside of the feeding hopper 14 is rotatably connected with a stirring crank 15 driven by a motor, and the two ends of the discharge port of the feeding hopper 14 are fixedly connected with a covering strip 16, which is slidably connected to the inside of the chute 7.
[0022] During the material discharge process, the material is first released from the discharge port at the bottom of the feeding hopper 14, and then enters the discharge pipe 5 through the feeding trough 6. The discharge pipe 5 is fixedly connected to the top of the support plate 3 by a bracket and is suspended in the middle position. There are two fixedly connected transport screws 8 inside. One end of the transport screw 8 extends to the outside of the discharge pipe 5, and the gears at its end mesh with each other and are driven to rotate by a motor. When the screw rotates, the material is pushed towards the open outlet at the far end of the discharge pipe 5 and is discharged from the protective sleeve 9 in the process. As the material is discharged, the weight of the material on the top of the support plate 3 gradually decreases. When the weight reduction reaches a preset threshold, the drive motor of the transport screw 8 stops running, so that the weight of the discharged material accurately matches the set value, thereby achieving accurate metering and feeding.
[0023] When the motion table 10 slides on top of the support plate 3, the guide groove 13 on its top drives the feeding hopper 14 to move outside the discharge pipe 5. The guide groove 13 is slidably connected to the discharge pipe 5, while the feeding hopper 14 is fixed to the top of the guide groove 13, and its discharge port is aligned with the feed trough 6. During the movement of the motion table 10, the cover strip 16 is fixedly connected to both ends of the discharge port of the feeding hopper 14 and is slidably embedded into the feed trough 6 through the slide groove 7. The cover strip 16 always covers the open part of the feed trough 6, maintaining the internal sealing of the discharge pipe 5 and preventing external interference with the flow of materials. The change in the position of the feeding hopper 14 will change the relative position of the discharge port on the top of the discharge pipe 5. The length of the conveying screw 8 is designed to cover the entire range of movement of the motion table 10 and the feeding hopper 14, so the conveying efficiency of the screw is not affected. When the material is discharged from the discharge port of the feeding hopper 14, the stirring crank 15 driven by the motor inside the feeding hopper 14 continuously rotates and stirs the material to prevent the material from clumping or blocking.
