Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The main rake tensioning apparatus of the utility model gate-type scraper, structure is as shown in Figure 1, include an adjusting screw rod 6, tune
The both ends of section screw rod 6 are socketed with axle sleeve 5, and tensioning wheel 8, the contact position of tensioning wheel 8 and axle sleeve 5 are socketed on two axle sleeves 5
It is provided with spacer ring 7, spacer ring 7 is fixedly attached to 5 surface of axle sleeve, and 7 surface of spacer ring is provided with boss, and boss is stuck in described
The inner surface of bearing up pulley 8 is socketed with sliding block 9,10 and of antiskid, shock-absorbing rubber ring on the adjusting screw rod 6 in two tensioning wheels, 8 outside successively
Location nut 2, adjusting screw rod 6 are provided at both ends with lubricating structure.
Lubricating structure includes the lubricating cup 1 for being fixed on 6 both ends section of adjusting screw rod, and lubricating cup 1 is connected with oil by lubrication channel 4
Pipe 3, the nozzle of oil pipe 3 are located at the junction of spacer ring 7 and axle sleeve 5.
Lubrication channel 4 is placed in the inside of adjusting screw rod 6.
Sliding block 9 is socketed in by slide block set on adjusting screw rod 6.
The width of axle sleeve 5 is more than the width of the tensioning wheel 8.
Oil pipe 3 is rubber hose.
The main rake tensioning apparatus of the utility model gate-type scraper, when use, as shown in Fig. 2, by adjusting screw rod 6
Both ends are fixed in the rack 13 of main target arm frame body 14 so that antiskid, shock-absorbing rubber ring 10 is contacted with rack, prevents adjusting screw rod 6
It is in direct contact, causes to wear during use and damages with rack, adjusting screw rod 6 is fixed on rack with location nut 2
On 13, then the rake chain 11 for harrowing 12 both sides of plate is sleeved on tensioning wheel 8, to which rake chain 11 is opened into and be fixed, prevents from harrowing
