The specific implementation mode is as follows:

the present invention will be further described with reference to the following specific embodiments and accompanying drawings.

Example 1:

as shown in fig. 1-4, an excavator counterweight includes a counterweight body 1, a groove 8 and more than one counterweight plate 2 are arranged on the counterweight body 1, the counterweight plate 2 is assembled in the groove 8 at the lower part of the counterweight body 1 through a fastener, a mounting hole is arranged on the counterweight plate 2, and the mounting hole is a stepped hole 9; the counterweight plate 2 is provided with 3-9 blocks in total.

Four step holes 9 are arranged on each balance weight plate 2, all the balance weight plates 2 are overlapped together and fixed on the balance weight body 1 through the double-end stud 5, and a group of gaskets 6 and nuts 7 are arranged in the step holes 9 on each layer of the balance weight plates 2.

The upper layer of the counterweight plate 2 is fixed through each group of gaskets 6 and nuts 7 arranged on the stud 5, the counterweight plate 2 at the lowest layer is directly fixed through the four groups of gaskets 6 and nuts 7, the installation in the stepped hole 9 is not needed, and the diameter of the larger hole of the stepped hole 9 is larger than the diameters of the gaskets 6 and the nuts 7.

The weight plates 2 are steel plates, preferably six weight plates, each weight plate is 176kg, when the weight of the weight plate needs to be reduced, one or more groups of gaskets 6 and nuts 7 are detached, and when the weight of the weight plate needs to be increased, each group of weight plates 2, gaskets 6 and nuts 7 are assembled.

Example 2:

as shown in fig. 5-6, an excavator counterweight includes a counterweight body 1, the counterweight body 1 is provided with a groove 8 and more than one counterweight plate 2, the counterweight plate 2 is assembled in the groove 8 at the lower part of the counterweight body 1 through a fastener, the counterweight plate 2 is provided with a mounting hole, and the mounting hole is a large hole 10 and a bolt hole 11.

The weight plate 2 is equipped with 9 ~ 15, divide into odd number board and even number board with all weight plate 2, be the odd number board if the bottom, the second layer from the beginning is the even number board, the third layer from the beginning is the odd number board, so on, set up two macropores 10 and two bolt holes 11 on every weight plate 2's diagonal angle, two macropores 10 and two bolt holes 11 become the rectangle and arrange, and the diameter of every macropore 10 is greater than the size of the head of bolt I3 and bolt II 4, odd number board and even number board use in turn and the macropore 10 on the odd number board and the bolt hole 11 concentric cooperation installation on the even number board, all weight plate 2 are fixed on the weight body 1 through bolt I3 and bolt II 4 after overlapping again. The bolts II 4 are arranged in the bolt holes 11, namely the bolts II 4 are arranged on the odd-numbered plate at the bottommost layer through two bolts II 4, and the bolts I3 penetrate through the large holes 10 on the odd-numbered plate at the bottommost layer and are directly arranged on the even-numbered plate at the penultimate layer.

The weight plates 2 are made of steel plates, preferably ten weight plates, each weight plate is 86kg, when the weight of the weight plate needs to be reduced, two bolts II 4 are detached, at the moment, the bolts I3 are not moved, the first weight plate 2 (namely the odd number plate at the bottommost layer) can be detached, and other weight plates 2 are still fastened by the bolts I3; when the second counterweight plate 2 (namely the even plate at the penultimate layer) is dismounted, the bolt II 4 is screwed again, namely the bolt II passes through the large hole 10 on the even plate at the penultimate layer and is directly arranged on the odd plate at the penultimate layer, and then the bolt I3 is dismounted, namely the second counterweight plate 2 (namely the even plate at the penultimate layer) is dismounted; the eleven counterweight plates 2 can be completely detached or completely attached by the circulation. Further, when the number of all the weight plates 2 is left by two thirds, the bolts i 3 and ii 4 need to be replaced with bolts shortened by one third, and similarly, when the number of all the weight plates 2 is left by one third, the bolts i 3 and ii 4 need to be replaced with bolts shortened by two thirds.
