Description
Technical field
The utility model relates to a kind of hand-held head of plastering.
Background technology
In the building trade, smearing in the mortar operation of indoor and outdoor wall, all be manually to use hawk, trowel to cooperate mortar is spread upon on the wall all the time, and then it is mortar is smooth floating with trowel, this method labor strength is big, complex procedures, production efficiency are low, the problem that also exists mortar to land, mortar loss is more, and the flatness of metope and smoothness are not easy control.
Application number is that 92240317.1 Chinese utility model patent manual discloses a kind of troweling machine, the head of plastering of this troweling machine is made up of motor, handle, sebific duct, the inside and outside sheet of plastering of vane type that the space separates is fixedly connected on the output shaft of motor, there is the center cavity that holds mortar at the center of the inside and outside sheet of plastering, the inside and outside sheet of plastering is covered with guard shield, the useful control button of controlling motor on the handle.During work; hold handle body of wall is applied strength, start button, motor-driven is connected in the inside and outside sheet rotation of plastering on the output shaft; being spread upon on the wall by the mortar that discharging opening enters center cavity that passes through in the sebific duct, guard shield has certain appearance ash and protective effect.But this troweling machine is because the structure of the inside and outside guard shield of plastering sheet and being spaced apart with the inside and outside sheet of plastering that has adopted that the space separates, and the inside and outside sheet of plastering also separates with the center cavity that holds ash, this all can't be avoided the problem that mortar lands in the work, also waste a large amount of mortar.And this troweling machine has strengthened the weight of the head of plastering because motor is arranged on the head of plastering of troweling machine, has so just additionally strengthened working strength of workers, has reduced operating efficiency.
The utility model content
The purpose of this utility model provides a kind of hand-held head of plastering, so that solve the problem that the existing head of plastering has a large amount of mortar to land at work.
The technical solution of the utility model is: a kind of hand-held head of plastering, comprise handle with mortar passage and the plastering plate that is rotatably installed on the handle, this plastering plate comprises the sheet of plastering, the described sheet of plastering is the disc sheet of plastering, be integrally formed with a re-entrant cavity that is used to hold ash in the disc sheet centre of plastering, there is a through hole at the center at the bottom of the chamber of this re-entrant cavity, and described mortar passage is communicated with re-entrant cavity by this through hole, and re-entrant cavity is provided with the slice mounting structure of plastering at the bottom of the chamber.
Have tubular installation shaft on the described handle, the tubular cavity in this installation shaft is the mortar passage; Described handle is provided with the gear drive that is used to drive the plastering plate rotation, the power input shaft of this gear drive rotates and is assemblied on the handle, power input shaft is provided with the flexible axle syndeton, the power output gear turning set of gear drive is contained in the leading section of installation shaft, and described plastering plate is fixed on the power output gear with one heart by the slice mounting structure of plastering.
The power output gear of described gear drive is an inner gear structure, power output gear and the driving gear engagement fit that is installed on the power input shaft.
The front port of described installation shaft is positioned at the plastering plate re-entrant cavity.
Described re-entrant cavity is rounded, and the sheet upper edge re-entrant cavity of plastering circumferentially has the bulk cargo groove uniformly at intervals, and each bulk cargo groove all is connected with re-entrant cavity.
Described bulk cargo groove is radially to be laid.
The described slice mounting structure of plastering is uniformly at intervals in the installing hole of described through hole periphery.
During use, with plastering plate towards wall, holding handle exerts pressure, after the energising work, mortar at first enters in the re-entrant cavity of plastering plate in the mortar passage, then along with the rotation of plastering plate, mortar is spread upon on the wall under at centrifugal force with by the effect of plastering plate applied pressure equably.The plastering plate of head has adopted the disc sheet of plastering owing to originally plaster, and the re-entrant cavity that holds ash is wholely set on plastering plate, plaster between sheet and the re-entrant cavity without any the gap, so when work, plastering plate, re-entrant cavity and between the walls have just constituted an enclosure space that holds mortar, in the process of plastering, mortar all is in the space of a relative closure all the time, mortar spreads upon on the wall once going out the re-entrant cavity sheet of being plastered, thereby significantly reduced the amount of dropping of mortar in the process of plastering, saved construction cost.
The utility model is provided with the gear drive that is used to drive the plastering plate rotation on handle, so just the plastering plate motor can be taken away other placement from the head of plastering, and during work, connects gear drive by flexible axle and gets final product.This structure is compared with in the prior art motor being set directly on the head of plastering, and has reduced the weight of the head of plastering, and makes a this light practicality of plastering.Gear drive adopts the internal tooth engaged transmission of driving gear and power output gear, and this mechanism structure is simple, and is safe and reliable, and working environment also greatly improves.
In the utility model, after setting up the bulk cargo groove on the plastering plate, mortar in the re-entrant cavity directly can be directed into the part that enforcement is plastered on the plastering plate, be convenient to hold the diffusion of mortar in the grey cavity on the one hand, the efficient of improved ash discharge, plastering, to hold ash on the other hand and smear organically merging, further reduce the amount of dropping of mortar.
