DETAILED DESCRIPTION
[0012] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0013] Embodiment: A stone material feeding device, such as Figure 1-Figure 2 As shown, it includes a lower hopper 1, which is tapered and wide at the front and narrow at the back, and the front end is higher than the rear end. A support plate 2 is provided on each of the left and right sides of the rear end of the lower hopper 1. A water spray head 3 is provided at the upper ends of the two support plates 2. A holder 4 is provided on the front surface of the upper ends of the two support plates 2. A cross bar 5 is arranged between the two holders 4. A plurality of shock-absorbing rubber rings 6 are sleeved on the cross bar 5 between the two holders 4. The lower ends of the plurality of shock-absorbing rubber rings 6 are against the surface of the lower hopper 1. Two damping rubber rings 6 are provided at the center of the lower hopper 1. A mounting hole 7 is provided on the lower surface of the lower hopper 1 corresponding to the mounting hole 7. A group of shaft groups 8 are provided. The shaft group 8 includes a roller shaft 9. The roller shaft 9 is placed in the mounting hole 7. A conveyor belt 10 is connected between the two roller shafts 9. A driven pulley 11 is fixedly connected to the end of the front roller shaft 9. A driving motor 12 is provided on the lower surface of the lower hopper 1. A driving pulley 13 is provided on the driving shaft of the driving motor 12.
