Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a 1 dustproof construction of electric hammer for electric power construction, including electric hammer 1, be provided with drill bit 2 on the electric hammer 1, and be provided with the fixing base 3 that is used for fixed drill bit 2 on the electric hammer 1, be close to 2 departments of drill bit on the electric hammer 1 and be provided with handle 4, be provided with dust cover 5 on the electric hammer 1, dust cover 5 lateral wall includes telescopic organ cover section 52. One end of the dust cover 5, which is far away from the electric hammer 1, is provided with a flexible rubber pad 53. Referring to fig. 3, a first through hole 51 for the drill bit 2 to pass through is formed in the bottom wall of the dust cover 5, a protective sleeve 6 penetrates through the first through hole 51, and a bearing 61 is arranged between the protective sleeve 6 and the through hole. The sheath is provided with protection casing 62 towards 3 direction integratively of fixing base, and protection casing 62 cover is established outside fixing base 3, and the protection casing 62 inner wall is provided with slipmat 63. The dust cover 5 is fixedly provided with a connecting rod 7 through a bolt, the free end of the connecting rod 7 is provided with a fixing ring 71, and the fixing ring 71 is sleeved on the handle 4. The dust cover 5 is arranged to prevent the dust generated by punching the electric hammer 1 and scattered massive building materials from falling down to cause dust raising or smashing constructors, and the dust generated by punching can be accumulated in the dust cover 5 and can be poured out of the dust cover 5 when reaching a certain amount. Meanwhile, the first 51 through holes are provided with the protective sleeves 6, the dust cover 5 and the drill bit 2 can be isolated by the protective sleeves 6, the dust cover 5 and the drill bit 2 are isolated, the situation that the dust cover 5 is damaged by contact with the dust cover 5 when the drill bit 2 rotates at a high speed is prevented, and the situation that the dust cover 5 rotates along with the drill bit 2 after contacting with the drill bit 2 to cause dust to be blown out is prevented. The setting of bearing 61 provides the support for between dust cover 5 and the protective sheath 6 on the one hand, and on the other hand has reduced the frictional force between dust cover 5 and the protective sheath 6, has prevented that the damage that hesitation long-time friction leads to between protective sheath 6 and the dust cover 5 from taking place. The setting of protection casing 62 can assist protective sheath 6 to fix protective sheath 6 on fixing base 3, make protective sheath 6 and protection casing 62 can follow fixing base 3 and rotate, avoided 2 flying speed of drill bit to rotate the condition emergence that protective sheath 6 led to the fact the injury suddenly among the in-process, on the other hand prevents that fixing base 3 from driving 2 pivoted in-process of drill bit to cause the injury to dust cover 5, can fix dust cover 5 on fixing base 3 simultaneously, played preliminary fixed effect. The provision of the anti-slip pad 63 can increase the frictional force between the protection shield 62 and the fixing base 3, thereby preventing the protection shield 62 from being detached from the fixing base 3. The arrangement of the connecting rod 7 and the fixing ring 71 can further fix the dust cover 5 on the electric hammer 1, and the fixing ring 71 can be hooped on the handle 4 and connected with the dust cover 5 through the connecting rod 7, so that the dust cover 5 is fixed on the electric hammer 1 at a fixed position, and the situation that the dust cover 5 is separated from the fixed position due to the vibration of the electric hammer 1 in the punching process is prevented.

Referring to fig. 2 and 3, the bottom wall of the dust cover 5 is obliquely arranged, a material discharging gate 66 is arranged at the lowest end of the bottom wall corresponding to the side wall of the dust cover 5, a sliding groove is formed in the side wall of the dust cover 5, the material discharging gate 66 is inserted into the sliding groove, the material discharging gate 66 can slide in the sliding groove, a convex block used for shifting the material discharging gate 66 is arranged on the material discharging gate 66, the dust can be concentrated at the lower end of the bottom wall of the obliquely arranged bottom wall of the dust cover 5, when the material discharging gate 66 is opened, the dust can be discharged from the material discharging gate 66, and the frequent operation that the dust cover 5 is inverted by workers is avoided.

Referring to fig. 3, in order to prevent dust from entering the bearing 61 or the gap between the protective sleeve 6 and the dust cover 5, a shielding cover 64 is fixedly provided on the bottom wall of the dust cover 5 at a position corresponding to the protective sleeve 6, and a second through hole 65 for the drill 2 to pass through is provided in the shielding cover 64. The provision of the shield cover 64 prevents dust from entering the gap between the protective cover 6 and the dust cover 5 to interfere with the rotation of the protective cover 6 and to damage the bearing 61 by entering the bearing 61.

The implementation principle of the embodiment is as follows: when using electric hammer 1 to carry out ascending operation of punching, pass through-hole one 51 and through-hole two 65 with drill bit 2, make the complete lock of protection casing 62 on fixing base 3, slipmat 63 hugs closely with fixing base 3, adjust the length of organ cover section 52 according to the on-the-spot condition simultaneously, make flexible rubber pad 53 and wall complete butt, later fix connecting rod 7 one end on dust cover 5, solid fixed ring 71 cover is established on handle 4, and pass through bolt fixed connection with connecting rod 7 free end and solid fixed ring 71, both can start electric hammer 1 and punch. When the raise dust that produces punches piles up to the certain degree in dust cover 5, stir the lug, make row bin gate 66 remove along the spout, the dust cover 5 diapire that slopes can be followed to accumulational raise dust in the dust cover 5 is poured out from arranging bin gate 66.
