When a balance weight is needed, the operator holds the balance weight with the left hand and uses a balance hammer to strike.

[0033] As Figure 3As shown, the material rack 22 includes a pair of bottom plates 221, a first side plate 222, a second side plate 223, a top plate 224, a first frame 225, a second frame 226, and four rollers 227; the four rollers 227 are respectively connected to the bottom of a pair of bottom plates 221; the first side plate 222 and the second side plate 223 are respectively vertically arranged on a bottom plate 221, the top plate 224 is arranged on the tops of the first side plate 222 and the second side plate 223 and is connected to the first side plate 222 and the second side plate 223; the first frame 225 and the second frame 226 are arranged between the first side plate 222 and the second side plate 223, and the first frame 225 is at a position close to a pair of bottom plates 221, and the second frame 226 is arranged on the lower surface of the top plate 224; both the first frame 225 and the second frame 226 are formed by connecting two horizontal longitudinal beams and two cross beams.

[0034] In this embodiment, the first frame 225 and the second frame 226 are made of 45mm square steel. The two horizontal longitudinal beams and two cross beams of the first frame 225 and the second frame 226 are formed by welding or fixed by connectors. The width of the second side plate 223 is greater than the width of the first side plate 222.

[0035] As Figure 4 shown, the material layer assembly 23 includes a motor 231, a gear 232, a rack 233, a material layer 234, a mounting plate 235, a first linear guide rail 236, a second linear guide rail 237, a third linear guide rail 238, and a mounting seat 239; the first linear guide rail 236 is arranged on the first side plate 222, and the second linear guide rail 237 and the third linear guide rail 238 are arranged on the second side plate 223 at intervals; one end of the material layer 234 is connected to the slider of the first linear guide rail 236, and the other end of the material layer 234 is connected to the sliders of the second linear guide rail 237 and the third linear guide rail 238; one end of the mounting plate 235 is fixed to the bottom plate 221, the other end of the mounting plate 235 is fixed to the top plate 224, and one side of the mounting plate 235 protrudes from the first side plate 222; the rack 232 is fixed on the mounting plate 235 along the height direction of the material rack 22, the motor 231 is connected to the material layer 234 through the mounting seat 235, the gear 232 is sleeved on the output shaft of the motor 231, and the gear 231 meshes with the rack 232 to drive the material layer 23 to move up and down along the rack 232.

[0036] Further, the material layer assembly 23 is provided with three layers, and four material boxes 24 are provided on each material layer 23, and the four material boxes 24 respectively contain different types of balance blocks. The types of balance blocks are distinguished according to the weight of the balance blocks. In this embodiment, there are 12 types of balance blocks, which are 50g, 75g, 100g, 125g, 150g, 175g, 200g, 225g, 250g, 275g, 300g, and 350g respectively.

[0037] There is a certain distance between the first frame 225 and the adjacent material layer assembly 23. The first frame 225 plays a supporting role. When the types of balance weights increase, the first frame 225 is also used to hold the material box 24.

[0038] The distance between two adjacent material layer assemblies 23 of each layer of material layer assemblies 23 can be automatically adjusted by the motor 231 according to the height of the material box 24.

[0039] In other embodiments, a position sensor is further provided on the outer side surface of the first side plate 222 for detecting the position of the material layer assembly 23.

[0040] As Figure 5 shown, the track assembly 1 includes a base plate 11, four parallel straight rods 12 arranged on the base plate 11, and an anti - tipping frame 13. Two of the four parallel straight rods 12 form a group, constituting two independent roller paths 14; two of the four rollers 227 are set in a group and arranged in the two roller paths 14; the anti - tipping frame 13 includes two U - shaped protective frames for preventing the material truck 2 from tipping over during operation. One of the two roller paths 14 is arranged between the two U - shaped protective frames.

[0041] In this embodiment, the material of the straight rod 12 is a square tube with a wall thickness of 5 mm, and the four parallel straight rods 12 are arranged on the 5 - mm - thick base plate 11. To ensure the smooth operation of the material truck 2, unilateral anti - tipping restriction is also carried out, that is, one of the two independent roller paths 14, which is closer to the operator, is placed between the two U - shaped protective frames to prevent the material truck 2 from tipping over towards the operator during operation. The U - shaped protective frame is welded by square tubes with a wall thickness of 5 mm.

[0042] The working process of the balance weight feeding device is described in combination with the attached drawings. When the operator needs to operate on the balance weight, when the operator steps on the pressure switch and presses the start button, the driving mechanism 21 extends to drive the material truck 2 to move along the track assembly 1 towards the operator. When the material truck 2 moves into place, the operator takes the balance weight that needs to be operated, and the driving mechanism 21 retracts to drive the material truck 2 to move along the track assembly 1 back to the original position. When it is necessary to change the types of balance weights in one or several of the material boxes 24, the distance between two adjacent material layers is adjusted by the motor 231.
