Abstract
The present invention discloses a water spray device of preventing the mud blockage for nozzles of a road sweeper, which comprises an annular spray pipe, a water pipe joint and a maintenance device for a spray pipe. The present invention is characterized in that more than two spray holes are arranged along the inner annular wall of the annular spray pipe; the maintenance device for a spray pipe is arranged in the position on the outer annular wall of the annular spray pipe, and the position faces upwards and corresponds to each spray hole; the water-pipe joint is arranged in the annular spray pipe. Compared with the nozzle of the current moisture-sweeping type road sweeper, the water spray device provided with two fan-shaped nozzles can better prevent the blockage of the nozzles by the mud, reduce failures and improves the operation speed and the labor intensity of operators of the road sweeper under the condition of corresponding water spray amount.
Description
Technical field
The invention belongs to the burnisher technical field, be specifically related to a kind of wet earth block prevent water spraying device of road sweeper suction nozzle of sweeping on the type road sweeper that is applied to.
Background technology
Having in the employed urban road road-sweeper of China at present is to inhale to sweep the wet type road-sweeper of sweeping of combination greatly, and this sweeping machine has that cleaning speed is fast, environment pollution is little, the cleaning efficiency advantages of higher.
Cause secondary pollution for fear of stirring up a cloud of dust, this sweeping machine is generally respectively being swept on the dish, all is being provided with water injector in the suction nozzle.The water injector of suction nozzle inside generally all is two fan nozzles, the spraying of this nozzle is fan-shaped distribution, big with the active area of upstream airflow, the penetration capacity of water smoke is relatively poor, water smoke leaves behind the spray orifice soon by the high velocity air band downstream, most of water concentrates near the aspiration channel wall, can't arrive the runner centre, caused near the dust of runner wall to become mud very soon with viscosity, the clod movement velocity is very high under the effect of air-flow, in case suction nozzle runner internal ring wall is gone up in collision, will be attached on tightly on the wall, clod is cumulative, the aspiration channel runner is blocked fully, cause sweeping machine not work, and this mud is because very closely knitly glutinous, be difficult in air-suction duct, clear, brought very big inconvenience for the sweeping machine operating personnel.
The city of China is in the construction period at present, and the dust in a lot of highway sections is more, and this has caused certain limitation for the use that the sweeping machine of fan nozzle is installed in the present suction nozzle.
Summary of the invention
Technical problem to be solved by this invention is the above-mentioned defective that exists at prior art, and a kind of wet type earth block prevent water spraying device of road sweeper suction nozzle of sweeping that can prevent effectively that earth from stopping up, fault is few, be convenient to safeguard is provided.
The technical scheme that solution the technology of the present invention problem is adopted is: a kind of earth block prevent water spraying device of road sweeper suction nozzle, comprise toroidal nozzle, water pipe head and spray orifice attending device, it is characterized in that offering spray orifice more than two along the toroidal nozzle internal ring wall, the water of described spray orifice ejection is column, the jet pipe attending device is arranged at the toroidal nozzle external annulus corresponding with each spray orifice position up, and described water pipe head is arranged on the toroidal nozzle.
The described spray orifice that is opened in the toroidal nozzle internal ring wall is 6, and described jet pipe attending device also is 6.
Described earth block prevent water spraying device of road sweeper suction nozzle is installed in suction nozzle suction inlet and aspiration channel transition position.
The beneficial effect that the present invention produced is: this device is installed in wet sweeping on the type road sweeper suction nozzle, water after boosting from water pump enters toroidal nozzle by joint, water enters the suction nozzle inner flow passage by the spray orifice on the toroidal nozzle, it is wetter to make suction nozzle runner inside contain the air-flow centre of a large amount of dust, reaches the purpose of eliminating airborne dust; And the part of pressing close to runner inner wall is dry, because dry dust stickiness is very little, the fault that earth stops up suction nozzle aspiration channel runner can not occur.The wet at present type suction nozzle of sweeping car of sweeping of this device is installed two fan nozzles under the suitable situation of injection flow rate, can prevent better that suction nozzle from being stopped up by earth, reduces fault, improves operating speed and sweeping machine labor intensity of operating personnel.

The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the present invention includes spray orifice attending device 1, toroidal nozzle 2 and water pipe head 3 and spray orifice 6, along toroidal nozzle 2 internal ring walls towards upper/lower positions, evenly offer the spray orifice 6 more than two, spray orifice attending device 1 is arranged at toroidal nozzle 2 external annulus corresponding with each spray orifice 6 position up, water pipe head 3 is arranged on the toroidal nozzle 2, and the spray orifice that is opened in toroidal nozzle 2 internal ring walls is 6.
As shown in Figure 3, Figure 4, whole device is installed in the intermediate location of suction inlet 5 and aspiration channel 4, water from water pump enters toroidal nozzle 2 through water pipe head 3, spray into suction nozzle runner central part through the spray orifice 6 on the toroidal nozzle 2 then, when air-flow entered the intermediate location of aspiration channel 4 from suction inlet 5, the water column interaction with spray orifice 6 ejections formed water smoke at the runner central part, enter aspiration channel 4 then, enter garbage collection box at last.
The water of toroidal nozzle 2 ejections is column, the water smoke of this column has stronger air-flow penetration capacity, circumferentially several water column that distributes is met to air-flow, arrive the runner centre, under the aerodynamic force effect of air-flow, water column is crashed to pieces into tiny water droplet, makes the dust in runner centre become clod, remains dry dust and use up wall part around the runner.In the runner downstream, even because the turbulent flow panting action, clod can bump to the aspiration channel inwall, but because clod will pass near the dried dust district of wall, dried dust can be rolled in around the clod, reduces the viscosity of clod, make clod not glue the aspiration channel inwall, reach the fault that overcomes the obstruction of aspiration channel runner.If contain impurity such as anvil cinder in the water spray orifice is stopped up, the plug that can back out on the spray orifice attending device 1 is cleared up.
