Description

一种清扫车进气机构及其清扫车An air intake mechanism for a sweeper and its sweeper

技术领域technical field

本实用新型涉及垃圾清扫技术领域,特别涉及一种清扫车进气机构及其清扫车。The utility model relates to the technical field of garbage cleaning, in particular to an air intake mechanism of a sweeper and a sweeper thereof.

背景技术Background technique

清扫车风道的主要工作对象主要是气固混合物,气体是空气,固体是暴露在街道中的垃圾颗粒物。在风道入口处的挡板容易将颗粒物等垃圾阻隔在外,使固体颗粒物处于滞止状态,不能被有效地吸入并清理。这种情况十分影响清扫车工作的真实效率。The main working object of the air duct of the sweeper is mainly the gas-solid mixture, the gas is the air, and the solid is the garbage particles exposed in the street. The baffle at the entrance of the air duct is easy to block the garbage such as particles, so that the solid particles are in a stagnant state and cannot be effectively inhaled and cleaned. This situation greatly affects the true efficiency of the sweeper's work.

此外,清扫车的风机除了要克服垃圾的自身重力做功之外,还要克服整个流道的风阻进行做功。现在市场上许多清扫车的风机的输出功主要用于克服后者的阻力,消耗了大量的非必需功,整机效率十分低下。垃圾在风道入口处只受到吸盘一个方向的吸力,垃圾中的固体颗粒物难以被吸盘吸收。In addition, the blower of the sweeper needs to overcome the wind resistance of the entire flow channel in addition to overcoming the gravity of the garbage to do work. At present, the output work of the fans of many sweepers on the market is mainly used to overcome the resistance of the latter, which consumes a lot of unnecessary work, and the efficiency of the whole machine is very low. The garbage is only sucked in one direction by the suction cup at the entrance of the air duct, and the solid particles in the garbage are difficult to be absorbed by the suction cup.

On the basis of sucking the gas-solid mixture by the suction cup, the vortex generator further reduces the wind resistance of the air duct, so as to absorb more gas-solid mixture.

请参阅图3,本实施例中所述槽孔211为长方体孔。由于长方体孔成方形结构,在挡板上制造正方体孔更为方便。Referring to FIG. 3 , the slot hole 211 in this embodiment is a rectangular parallelepiped hole. Since the cuboid holes have a square structure, it is more convenient to manufacture the cuboid holes on the baffle.

优选的,所述槽孔211的数量为2个以上,所述槽孔211均匀排布在所述挡板21上。槽孔的数量直接影响到空气的流通,槽孔数量越多,空气流通面积的增大,系统的风阻明显降低,减小了清扫车副发动机的能耗。在本实施例中,槽孔的数量为11个,均匀地排布在挡板上,一方面槽孔的数量足够多,空气流通面积足够大,能有效地较小清扫车发动机的能耗;另一方面槽孔的数量为11个更方便加工。Preferably, the number of the slot holes 211 is two or more, and the slot holes 211 are evenly arranged on the baffle plate 21 . The number of slots directly affects the air circulation. The more the number of slots, the larger the air circulation area, the significantly lower the wind resistance of the system, and the lower the energy consumption of the auxiliary engine of the sweeper. In this embodiment, the number of slot holes is 11, which are evenly arranged on the baffle plate. On the one hand, the number of slot holes is large enough, and the air circulation area is large enough, which can effectively reduce the energy consumption of the sweeper engine; On the other hand, the number of slot holes is 11 more convenient for processing.

优选的,相邻两槽孔的距离(b)为25mm-40mm。相邻两槽孔的距离不宜太密,从而影响槽孔的制造。相邻两槽孔的距离(b)为25mm-40mm能更方便在挡板上制造槽孔。Preferably, the distance (b) between two adjacent slot holes is 25mm-40mm. The distance between two adjacent slot holes should not be too dense, thus affecting the manufacture of the slot holes. The distance (b) between the two adjacent slot holes is 25mm-40mm, which can make it more convenient to manufacture the slot holes on the baffle plate.

优选的,所述槽孔211到所述挡板21侧边的距离(a)为30mm-55mm。清扫垃圾时,槽孔的排布直接影响到空气流通的效果。设置槽孔到挡板侧边的距离(a)为30mm-55mm,能更好地达到空气流通的效果,从而降低清扫车发动机的耗损。Preferably, the distance (a) from the slot hole 211 to the side edge of the baffle 21 is 30mm-55mm. When cleaning garbage, the arrangement of slot holes directly affects the effect of air circulation. Setting the distance (a) from the slot to the side of the baffle is 30mm-55mm, which can better achieve the effect of air circulation, thereby reducing the consumption of the sweeper engine.

本实施例中,发明人还提供了一种清扫车,包括清扫车进气机构和车辆底盘,所述清扫车进气机构设置在所述车辆底盘上。在清扫车清扫垃圾时,由于清扫车底盘设置的清洗车进气机构将清扫车内部的空气抽取排出清扫车外,导致清洗车内外气压失衡。为了保持内外气压的平衡,清扫车进气机构的吸盘运作,吸取地上的垃圾,将垃圾吸入清扫车内,从而实现垃圾的清扫。In this embodiment, the inventor also provides a sweeper, including a sweeper air intake mechanism and a vehicle chassis, and the sweeper air intake mechanism is provided on the vehicle chassis. When the sweeper sweeps garbage, the air pressure inside and outside the sweeper is unbalanced because the sweeper air intake mechanism set on the sweeper chassis draws the air inside the sweeper out of the sweeper. In order to maintain the balance of internal and external air pressure, the suction cup of the air intake mechanism of the sweeper operates to absorb the garbage on the ground and suck the garbage into the sweeper, so as to realize the cleaning of the garbage.

区别于现有技术,上述技术方案通过在所述挡板上设置有槽孔,所述离心风机用于为所述吸盘提供吸力;此时,在风道管路入口处产生的局部的涡,从而降低颗粒物的起跳速度,有利于固体颗粒物被吸收。同时,由于设置槽孔使得整体流通面积的增大,系统的风阻明显降低,减小了清扫车副发动机的能耗,达到了节能减排的目的。Different from the prior art, the above technical solution is provided with slots on the baffle, and the centrifugal fan is used to provide suction for the suction cup; at this time, the local vortex generated at the inlet of the air duct pipeline, Thereby, the take-off speed of the particles is reduced, which is conducive to the absorption of solid particles. At the same time, due to the increase of the overall flow area due to the slotted holes, the wind resistance of the system is significantly reduced, the energy consumption of the auxiliary engine of the sweeper is reduced, and the purpose of energy saving and emission reduction is achieved.
