Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically to a high-precision feed scale stabilization structure. Background Technology

[0002] Feed is a general term for the food of all animals raised by humans. During feed production, raw materials are often pre-processed directly. After the raw materials are ground to a suitable fineness, they are weighed through the weighing hopper in the batching structure. Then, the various raw materials are directly fed into the mixing device in the appropriate proportions and mixed. After that, they are pelleted to become feed.

[0003] The prior art discloses a feed production ingredient structure (publication number: CN219150024U), which includes a weighing hopper, a fixed frame fixedly connected to the outside of the weighing hopper, a weighing sensor tightly attached to the bottom of the fixed frame, a support frame fixedly connected to the bottom of the weighing sensor, a feeding valve fixedly connected to the bottom of the weighing hopper, a feeding hopper provided inside the weighing hopper, a feeding ring fixedly connected to the upper outside of the feeding hopper, and a rubber sleeve tightly attached to the lower outside of the feeding hopper;

[0004] However, the above-mentioned technical solutions and existing technologies still have the following drawbacks: During use, the device supports the weighing hopper by tightly fitting the bottom of the fixed frame on the outside of the weighing hopper with the weighing sensor fixed on the support frame, and uses the weighing sensor to weigh and dispense feed; the weighing sensor needs to be regularly maintained and calibrated to ensure the measurement accuracy and stability of the sensor. However, during the maintenance of the weighing sensor, the weighing hopper needs to be removed from the support frame, which causes inconvenience during the maintenance of the weighing sensor and affects work efficiency.

[0005] Therefore, we propose a high-precision feed scale stabilization structure. Utility Model Content

[0006] The purpose of this invention is to provide a stable structure for a high-precision feed scale to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-precision feed scale stabilization structure, comprising a support plate, a bracket fixedly installed at the bottom of the support plate, a weighing sensor fixedly installed at the top of the support plate, a drive motor fixedly installed at the top of the support plate, a bidirectional lead screw rotatably connected to the top of the support plate on both sides of the weighing sensor, a connecting plate detachably installed at the top of the weighing sensor, a weighing hopper fixedly installed through the middle of the connecting plate, the output end of the drive motor fixedly installed to one end of the bidirectional lead screw, a moving block threadedly connected to the bidirectional lead screw, a support rod rotatably connected to the top of the moving block, and a lifting plate located below the connecting plate rotatably connected to the top of the support rod.

[0008] Optionally, two bidirectional lead screws are arranged in parallel, and the output end of the drive motor is fixedly installed to one end of one bidirectional lead screw.

[0009] Optionally, a first synchronous pulley is fixedly installed at one end of one of the bidirectional lead screws, and a second synchronous pulley is fixedly installed at one end of the other bidirectional lead screw. The first synchronous pulley is connected to the second synchronous pulley via a synchronous belt.

[0010] Optionally, the two moving blocks are symmetrically arranged at both ends of a bidirectional lead screw, and the support rod and the lifting plate are located directly above the bidirectional lead screw. When the lifting plate is at its lowest position, it is lower than the lowest end of the weighing sensor's stroke.

[0011] Optionally, a guide rail located directly below the bidirectional lead screw is fixedly installed on the top of the support plate, the bottom of the moving block is slidably connected to the guide rail, and a guide rod is fixedly installed on the top of the support plate, the guide rod being slidably connected to the connecting plate through a linear bearing.

[0012] Optionally, the support plate has an inner cavity in the middle, the diameter of which is larger than the diameter of the weighing hopper, and the weighing sensors are evenly arranged around the inner cavity.

[0013] Optionally, the four brackets are fixedly installed at the four corners of the bottom of the support plate, and the height of the brackets is greater than the height of the weighing hopper.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This high-precision feed scale features a stable structure with a bidirectional lead screw. When the weighing hopper needs to be lifted for maintenance of the weighing sensor, the drive motor rotates one bidirectional lead screw, which in turn rotates the other bidirectional lead screw via the first and second synchronous pulleys. This causes two moving blocks to move along the guide rail towards the center, which in turn lifts the support plate, the connecting plate, and the weighing hopper. This allows the connecting plate to separate from the weighing sensor, enabling the vertical lifting and lowering of the weighing hopper. This facilitates the lifting of the weighing hopper while ensuring its stability, and allows for regular inspection and maintenance of the weighing sensor, ensuring accurate and stable weighing measurements.

[0020] 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.

[0021] Please see Figures 1 to 3This utility model provides a high-precision feed scale stabilization structure, including a support plate 1, a bracket 2 fixedly installed at the bottom of the support plate 1, a weighing sensor 4 fixedly installed at the top of the support plate 1, a drive motor 8 fixedly installed at the top of the support plate 1, a bidirectional lead screw 7 rotatably connected to the top of the support plate 1 on both sides of the weighing sensor 4, a connecting plate 5 detachably installed at the top of the weighing sensor 4, a weighing hopper 6 fixedly installed through the middle of the connecting plate 5, the output end of the drive motor 8 fixedly installed to one end of the bidirectional lead screw 7, a moving block 9 threadedly connected to the bidirectional lead screw 7, a support rod 10 rotatably connected to the top of the moving block 9, and a lifting plate 11 located below the connecting plate 5 rotatably connected to the top of the support rod 10. By setting up the bidirectional lead screw 7, the weighing hopper 6 needs to be lifted to inspect the weighing sensor 4. During the inspection, the drive motor 8 drives one bidirectional lead screw 7 to rotate, and at the same time, the first synchronous wheel 12 and the second synchronous wheel 13 drive the other bidirectional lead screw 7 to rotate synchronously. This causes the two moving blocks 9 to move towards the center along the guide rail 15, which in turn causes the support rod 10 to lift the support plate 1, thereby lifting the connecting plate 5 and the weighing hopper 6. This separates the connecting plate 5 from the weighing sensor 4, realizing the vertical lifting and lowering function of the weighing hopper 6. This facilitates the lifting of the weighing hopper 6 and ensures its stability, and facilitates the regular inspection and maintenance of the weighing sensor 4, ensuring its accurate and stable weighing measurement and normal operation.

[0022] Two bidirectional lead screws 7 are arranged in parallel, and the output end of the drive motor 8 is fixedly installed at one end of one bidirectional lead screw 7.

[0023] One end of a double-acting lead screw 7 is fixedly mounted with a first synchronous pulley 12, and the other end of a double-acting lead screw 7 is fixedly mounted with a second synchronous pulley 13. The first synchronous pulley 12 is connected to the second synchronous pulley 13 via a synchronous belt 14.

[0024] Two movable blocks 9 are symmetrically arranged at both ends of a bidirectional lead screw 7. The support rod 10 and the lifting plate 11 are located directly above the bidirectional lead screw 7. When the lifting plate 11 is at its lowest position, it is lower than the lowest end of the stroke of the load cell 4.

[0025] A guide rail 15 located directly below the bidirectional lead screw 7 is fixedly installed on the top of the support plate 1. The bottom of the moving block 9 is slidably connected to the guide rail 15. A guide rod 16 is fixedly installed on the top of the support plate 1. The guide rod 16 is slidably connected to the connecting plate 5 through a linear bearing.

[0026] The support plate 1 has an inner cavity 3 in the middle. The diameter of the inner cavity 3 is larger than the diameter of the weighing hopper 6. The weighing sensors 4 are evenly arranged around the inner cavity 3.

[0027] The four brackets 2 are fixedly installed at the four corners of the bottom of the support plate 1, and the height of the brackets 2 is greater than the height of the weighing hopper 6.

[0028] Working principle:

[0029] The weighing hopper 6 needs to be lifted to inspect the weighing sensor 4. During the inspection, the drive motor 8 drives one bidirectional lead screw 7 to rotate, and simultaneously drives another bidirectional lead screw 7 to rotate synchronously through the first synchronous wheel 12 and the second synchronous wheel 13. This causes the two moving blocks 9 to move towards the center along the guide rail 15, which in turn causes the support rod 10 to lift the support plate 1, thereby lifting the connecting plate 5 and the weighing hopper 6. This separates the connecting plate 5 from the weighing sensor 4, realizing the vertical lifting and lowering function of the weighing hopper 6. This facilitates the lifting of the weighing hopper 6 and ensures its stability, and also facilitates the regular inspection and maintenance of the weighing sensor 4, ensuring its accurate and stable weighing measurement and normal operation.
