[0030] Furthermore, a gravel collecting device 12 is provided below the left side of the support plate 5, and the gravel collecting device 12 includes a gravel collecting vehicle 13 and a collecting baffle 14. The gravel collecting vehicle 13 is detachably connected to the support plate 5, and the upper end of the collecting baffle 14 is fixedly connected to the lower end of the support plate 5. The gravel collected by the collecting iron net 7 is transported to the top of the gravel collecting vehicle 13 by the transport rod 8 and then put into the gravel collecting vehicle 13, which is convenient for subsequent processing and continued use. The collecting baffle 14 is used to position the collecting iron net 7 to ensure that the collecting iron net 7 can be moved to the top of the gravel collecting vehicle 13.

[0033] Example 2

[0034] See attached Figure 1-7 The difference between this embodiment and embodiment 1 is that a counterweight block 27 is fixedly connected to the right side of the collecting iron net 7. By setting the counterweight block 27, when there is no stone inside the collecting iron net 7, the left side of the collecting iron net 7 can naturally rotate upward to ensure that after the stone collecting vehicle 13 completes the collection, the spring block 20 is connected to the L-shaped slot 26.

[0035] Furthermore, the collecting iron net 7 is configured as a hollow inverted quadrangular pyramid structure, and an iron net opening 28 is provided at the upper left end of the hollow inverted quadrangular pyramid structure. The iron net opening 28 ensures that when the collecting iron net 7 moves to the left, the trapezoidal plate 17 can pass through the iron net opening 28 to push the left side of the collecting iron net 7 to rotate downward, and at the same time ensures that when the gravel collecting vehicle 13 collects gravel, the gravel can flow out from the left side of the collecting iron net 7 to prevent the gravel from falling outside the gravel collecting vehicle 13.

[0036] Furthermore, a rectangular opening 29 is provided in the middle of the right side of the support plate 5, and the rectangular opening 29 extends the transport track 9 at the lower end of the support plate 5, which can reduce the leverage force of the stones in the collecting iron net 7 received by the transport rod 8 to prevent equipment damage. The stones pass through the rectangular opening 29 and fall into the collecting iron net 7, preventing the stones from falling on the support plate 5.
