[0010] Preferably, a material guide plate is fixedly provided on the inner wall of the moving box, and the material guide plate is rotatably sleeved with the output shaft of the motor. A plurality of discharge pipes are fixedly sleeved on the side wall of the moving box, and a plurality of material collection boxes are provided on the side wall of the moving box. The other end of each of the discharge pipes passes through the corresponding material collection box and is fixedly connected to the corresponding material collection box.

[0011] Preferably, a limiting plate is arranged inside each limiting groove, and the other end of each limiting rod is fixedly connected to the corresponding limiting plate.

[0012] Preferably, a telescopic rod is fixedly provided on the top of the bottom plate, and the other end of the telescopic rod is fixedly connected to the moving box.

[0013] Preferably, a mounting plate is fixedly provided on the side wall of each aggregate box, and each mounting plate is threadedly connected to the side wall of the moving box by means of bolts.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The utility model provides a sealing plate, which is a square-shaped plate. The sealing plate is movably plugged into the inside of the plug-in slot, the electric push rod and the motor are started and one end of the drill rod is brought close to the top plate. The sealing plate sticks to the top plate before the drill rod. When the electric push rod continues to operate, the sealing plate moves inside the plug-in slot through an elastic mechanism, so that the sealing plate can continuously seal the drilling process of the drill rod to prevent dust from falling during the drilling process, thereby providing a certain degree of protection for the user.

[0016] 2. The utility model sets up an elastic mechanism, which includes multiple springs and multiple limit rods. When the electric push rod pushes the moving box to move upward, the sealing plate is preferentially pressed against the top plate. When the electric push rod drives the moving box to continue to rise, the multiple springs are compressed synchronously, thereby ensuring that the sealing plate can move smoothly inside the plug-in slot and can also ensure that the sealing plate is always in contact with the top plate during the drilling process.

[0017] 3. In the utility model, by setting the guide plate and multiple discharge pipes, the dust and sand particles dropped from the drilling holes can be smoothly moved to the inside of the multiple discharge pipes through the guide plate, and the sand particles can be smoothly transported to the inside of the multiple collection boxes through the multiple discharge pipes, so that the dust and sand particles can be collected.
