The protrusions on both sides of the ladle are usually set for hoisting, and the supporting grooves 5 are set to ensure the stability of the ladle when it falls.

[0029] Reference Figure 1 and Figure 2 , sleeves 6 are extended downward at the ends of the two support plates 4, and the four sleeves 6 correspond to the four angle areas of the weighing platform 2 respectively. Guide rods 7 corresponding to the sleeves 6 are vertically fixed on the four angle areas of the upper surface of the weighing platform 2. The upper end of each guide rod 7 extends into the corresponding lumen of the sleeve 6, and the diameter of the lumen of the sleeve 6 is just consistent with the diameter of the guide rod 7 to ensure that the sleeve 6 can stably move along the axial direction of the guide rod 7, that is, move up and down; a convex column 8 is extended radially outward at the lower end of the sleeve 6, and a groove 9 is provided on the upper surface of the weighing platform 2 adjacent to the guide rod 7, so that the number of grooves 9 is consistent with the number of guide rods 7, and four are provided, and the extension direction of the groove 9 is consistent with the left and right direction of the weighing platform 2.

[0030] Reference Figure 1 , Figure 2 and Figure 3A telescopic buffer arm is provided between the lower end of the sleeve 6 and the adjacent groove 9, one end of the telescopic buffer arm is hinged to the lower end of the sleeve 6, and the other end of the telescopic buffer arm obliquely extends into the corresponding groove 9 and is hinged thereto, so that the sleeve 6 squeezes the telescopic buffer arm during the downward sliding of the guide rod 7; specifically, the telescopic buffer arm includes: a first U-shaped plate 10, a second U-shaped plate 11, a first pressing plate 12 and a second pressing plate 13, the U-shaped opening of the first U-shaped plate 10 faces the lower end of the adjacent sleeve 6, and the side plate of the first U-shaped plate 10 is rotated to sleeve the sleeve The first U-shaped plate 10 is hinged to the lower end of the sleeve 6, and the U-shaped opening of the second U-shaped plate 11 faces the adjacent groove 9, and the second U-shaped plate 11 is hinged inside the groove 9; the first pressing plate 12 and the second pressing plate 13 are located between the first U-shaped plate 10 and the second U-shaped plate 11, and the first pressing plate 12 is adjacent to the second U-shaped plate 11, and the second pressing plate 13 is adjacent to the first U-shaped plate 10, and the first U-shaped plate 10 and the first pressing plate 12 are connected by a pair of first connecting columns 14, and the first The connecting column 14 passes through the second pressure plate 13, and the second U-shaped plate 11 is connected to the second pressure plate 13 through a pair of second connecting columns 15. The second connecting column 15 passes through the first pressure plate 12, wherein the first connecting column 14 and the second connecting column 15 are diagonally arranged and staggered to avoid mutual interference during movement. The first connecting column 14 and the second connecting column 15 are correspondingly sleeved with a first compression spring 16 and a second compression spring 17 on the outside. The first compression spring 16 is located between the first U-shaped plate 10 and the second pressure plate 13, and the second compression spring 17 is located between the second U shaped plate 11 and the first pressure plate 12; based on this, when the support plate 4 is subjected to force, the sleeve 6 will slide downward along the guide rod 7 to squeeze the first U-shaped plate 10, and then the first pressure plate 12 connected to the first U-shaped plate 10 will squeeze the second compression spring 17 located between the second U-shaped plate 11 and the first pressure plate 12, and at the same time, the second pressure plate 13 connected to the second U-shaped plate 11 will squeeze the first compression spring 16 located between the first U-shaped plate 10 and the second pressure plate 13, thereby unloading the force on the sleeve 6, and then buffering the force exerted on the support plate 4.

[0031] In this embodiment, the width of the groove 9 is adapted to the width of the second U-shaped plate 11, so that the two side plates of the second U-shaped plate 11 are in close contact with the inner walls of the groove 9 on both sides, thereby enhancing the resistance strength of the second U-shaped plate 11 to the stress on the front and rear sides; with the support of the telescopic buffer arm, the lateral stress transmitted to the guide rod 7 through the sleeve 6 will be greatly reduced, thereby ensuring the firmness of the connection between the guide rod 7 and the weighing platform 2, thereby ensuring the stability of the support system of the device.

[0032] During actual use, the lifting equipment is used to gradually lower the supporting grooves 5 on the two support plates 4 corresponding to the protrusions on both sides of the ladle, so that the protrusions on both sides of the ladle fall into the corresponding supporting grooves 5 first. At this time, there is still a certain distance between the bottom of the ladle and the top surface of the weighing platform 2. The ladle is continued to be lowered, and the lower end of the sleeve 6 will squeeze the telescopic buffer arm. The telescopic buffer arm is used to slow down the impact force exerted by the ladle on the sleeve 6, and the gravitational potential energy of the ladle is reduced, thereby ensuring that the weighing platform 2 will not be overloaded after the ladle is placed on the weighing platform 2. Finally, the lifting equipment is removed, and the weight value of the ladle can be checked in real time according to the gravity sensor.

[0033] The ladle weighing device provided in this embodiment can cushion the ladle that is about to fall onto the weighing platform 2, so as to reduce the impact of the ladle on the weighing platform 2, thereby achieving the purpose of unloading the ladle and avoiding the problem of damage to the weighing platform 2 due to excessive load.

[0034] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
