[0002] Top hammer hydraulic drill is a kind of drilling equipment commonly used in geological exploration, mining and foundation engineering. It uses a hydraulic system to drive the top hammer to impact and propel the drill bit to complete the drilling operation.

[0003] For example, the utility model with application number CN202122714988.6 discloses a drilling rig propulsion beam assembly that is convenient for manual disassembly and assembly of drill rods. The utility model inserts drill rod 2 into clamp arm 2, and the clamping cylinder pulls clamp arm 1 to clamp drill rod 2, and then the lifting hydraulic motor drives the sliding mechanism through the transmission chain to move the slewing head up and down, and pulls the slewing head under the action of the lifting cylinder to rotate drill rod 1, and then drill rod 1 contacts drill rod 2, and the rotary hydraulic motor drives drill rod 1 to rotate, so that drill rod 1 and drill rod 2 are fixed. However, in the actual use of this type of propulsion structure, since the transmission chain is exposed to the outside, it is easy to adhere to dust, which aggravates the wear of the transmission chain.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a propulsion structure of a top hammer hydraulic drill is provided. Utility Model Content

[0008] Furthermore, the driving assembly includes a hydraulic motor and a driving sprocket. The hydraulic motor is fixed to the lower end of one side of the protective shell, and one end of the hydraulic motor is connected to the driving sprocket.

[0009] Furthermore, the driving assembly also includes a chain and a slide seat, the chain is sleeved on the outer side of the driving sprocket, and the slide seat is fixed to the end of the chain.

[0010] Furthermore, the fixing plate is fixedly connected to the protective shell, and the opening width of the protective shell is substantially equal to the width of the sliding seat.

[0011] Furthermore, the driving assembly also includes a guide rod and a driven sprocket, one end of the slide seat is slidably connected to the guide rod, and the guide rod is fixedly connected to the protective shell, and the upper end of the protective shell is rotatably connected to the driven sprocket.

[0014] The utility model provides a propulsion structure of a top hammer hydraulic drill, which has the following beneficial effects:

[0015] 1. The utility model can use the blocking cloth to cover the opening of the protective shell through the setting of the protective component to prevent dust from entering the protective shell and contaminating the chain. At the same time, the hydraulic motor will pull the chain through the active sprocket, so that when the slide moves on the guide rod, the protective box will move synchronously. At this time, the spring will rotate the reel under the limit of the connecting plate, automatically reeling in the loose blocking cloth, and the blocking cloth at the other end will be stretched. Therefore, during the movement of the slide, the protective shell can also be covered. At the same time, the magnetic strip can also absorb the iron protective shell, thereby improving the fit between the blocking cloth and the protective shell, and further improving the dustproof performance of the propulsion structure;

[0016] 2. Through the provision of the impurity removal component, the utility model enables the fan to deliver the airflow into the shunt pipe and spray it toward the chain from the nozzle, thereby utilizing a relatively high air pressure to blow off the dust impurities on the chain. At the same time, the fan forms a negative pressure inside the filter box through the connecting pipe, and can perform air suction, so that the blown-off dust can be trapped in the filter screen inside the filter box, which is beneficial to extending the service life of the propulsion structure.
