Description

Technical Field

[0001] This utility model relates to the field of feed batching scale technology, specifically to an anti-eccentric loading mechanism for the weighing platform of a feed batching scale. Background Technology

[0002] In the feed production process, feed batching scales are crucial equipment, as their weighing accuracy directly affects feed quality. The weighing platform is one of the key components of a feed batching scale; however, in actual use, the distribution of materials on the weighing platform is often uneven, easily leading to unbalanced loading.

[0003] Currently, the existing anti-eccentric loading measures of feed batching scales have limited effectiveness and cannot adapt well to changes in the characteristics of different materials and production environments. Eccentric loading not only causes uneven force on the weighing sensors, resulting in large errors in the weighing results and affecting the accuracy of feed formulation, but also accelerates the damage of the weighing sensors in the long term, shortens their service life, increases equipment maintenance costs and downtime, and greatly reduces production efficiency. Utility Model Content

[0006] The weighing mechanism includes four support columns fixedly installed at the bottom of the weighing platform, and a weighing sensor is fixedly installed at the bottom of each of the four support columns. The weighing sensor is fixedly installed inside the support frame and is electrically connected to an external weighing display controller to measure the weight of the material at the top of the weighing platform.

[0012] Mounting plates are fixedly installed around the bottom of the weighing platform. A transition spherical surface is fixedly installed at the bottom of the mounting plate, and the transition spherical surface and the transition spherical bowl groove are slidably connected.

[0013] Preferably, a second spring is fixedly installed on the top of the second fixing seat, and the top end of the second spring is fixedly connected to the bottom of the column to drive the transition ball bowl groove to always fit against the transition ball surface.

[0014] Preferably, a buffer component is fixedly installed on the top of the support frame, and the top of the buffer component is provided with a plurality of buffer protrusions, the top of the buffer protrusions being in contact with the bottom of the weighing platform.

[0025] 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.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a weighing platform anti-eccentricity mechanism for a feed batching scale, including a support frame 1 and a weighing platform 2 installed on its top, and a weighing mechanism 3 for weighing feed batching is installed between the support frame 1 and the weighing platform 2.

[0027] The weighing mechanism 3 includes four support columns 31 fixedly installed at the bottom of the weighing platform 2, and a weighing sensor 32 is fixedly installed at the bottom of each of the four support columns 31. The weighing sensor 32 is fixedly installed inside the support frame 1 and is electrically connected to an external weighing display controller to measure the weight of the material at the top of the weighing platform 2.

[0028] Anti-eccentric load components 33 are installed around the bottom of the weighing platform 2 to make timely adjustments when the material is unbalanced.

[0029] Auxiliary components 34 are installed on all four sides inside the support frame 1 to further reduce the occurrence rate of off-center load.

[0030] Reference Figure 2 as well as Figure 3As shown, the anti-eccentric load assembly 33 includes four guide rods 331 fixedly installed around the inside of the support frame 1. A first fixed seat 332 is fixedly installed around the bottom of the weighing platform 2. Sliding sleeves 333 are slidably installed on the surface of each of the four guide rods 331. A first spring 334 is fixedly installed on the top of the sliding sleeve 333. The top of the first spring 334 is fixedly connected to the bottom of the first fixed seat 332.

[0031] In this embodiment, when the weighing platform 2 is unbalanced, the elastic cooperation between the sliding sleeve 333 and the first spring 334 is used to lift the unbalanced side of the weighing platform 2. This not only balances the unbalanced load on the weighing platform 2 in a timely manner, keeping the weighing platform 2 horizontal, but also greatly improves the weighing accuracy.

[0032] Reference Figure 2 as well as Figure 4 As shown, the auxiliary component 34 includes four second fixed seats 341 fixedly installed around the inside of the support frame 1. A column 342 is provided on the top of the second fixed seat 341, and a transition ball groove 343 is opened on the top of the column 342. Mounting plates 344 are fixedly installed around the bottom of the weighing platform 2. A transition ball surface 345 is fixedly installed on the bottom of the mounting plate 344. The transition ball surface 345 and the transition ball groove 343 are slidably connected. A second spring 346 is fixedly installed on the top of the second fixed seat 341. The top of the second spring 346 is fixedly connected to the bottom of the column 342 to drive the transition ball groove 343 to always be in contact with the transition ball surface 345.

[0033] In this embodiment, when the weighing platform 2 is unbalanced, the transition spherical surface 345 on one side of the bottom of the weighing platform 2 is lowered and cooperates with the transition spherical bowl groove 343 to make a certain range of adaptive adjustment to the weighing platform 2, thereby further maintaining the levelness of the weighing platform 2, reducing the impact of unbalanced load on the weighing sensor 32, and improving the weighing accuracy.

[0034] Reference Figure 1 As shown, a buffer 4 is fixedly installed on the top of the support frame 1. Several buffer protrusions 5 are provided on the top of the buffer 4. The top of the buffer protrusions 5 is in contact with the bottom of the weighing platform 2. There are multiple buffer protrusions 5, and the multiple buffer protrusions 5 are arranged at equal intervals on the top of the buffer 4. The buffer 4 and the buffer protrusions 5 are both made of rubber components to increase the buffering effect and friction.

[0035] In this embodiment, the buffer 4 and the buffer protrusion 5 can buffer the impact force generated by the off-center load, reduce the damage to the weighing sensor 32, extend the service life of the weighing sensor 32, and reduce the maintenance cost of the equipment.

[0036] Working principle: When feed ingredients are placed on top of the weighing platform 2, if there is an off-center load, the weighing platform 2 will tilt. At this time, the first spring 334 and sliding sleeve 333 on the tilted side will be stretched, while the first spring 334 and sliding sleeve 333 on the other side will be compressed, causing the sliding sleeve 333 to slide on the surface of the guide rod 331. The elastic action of the first spring 334 is used to balance the off-center load of the weighing platform 2, so that the weighing platform 2 is kept as horizontal as possible. At the same time, the buffer 4 can further buffer the impact force generated by the off-center load, reducing the influence on the weighing sensor 32.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
