Description
Technical Field
The invention relates to a working cart, in particular to a working cart with a built-in dust collection system.
Background
In cutting (cutting), grinding (polishing), polishing (polishing) and other operations of materials such as woodworking, sheet metal, stone countertops, building decoration, glass fiber and the like, tool machines such as cutting tools (cutting tools), grinding machines (grinders), polishing machines (polishers) and the like are often used. For example, when the grinding operation is performed by using a grinding machine, the grinding machine is firstly used from a rotary grinding machine (Rotation grinding machine) with the coarsest grinding particle size, then an eccentric grinding machine (Orbital grinding machine) with the medium grinding is used, and finally a random motion eccentric grinding machine (Random Orbital Sander) with the finest grinding particle size is used, and the thickness of grinding consumables is also from #24, #60, #100, to #1000, #2000, #5000, which are coarsest. In order to respond to different materials of different objects to be polished, the materials used for polishing consumables are different. In this way, the operator is equipped with a plurality of tools and various consumables in the Working area, and a Working cart (Working Trolley) for placing the tools and consumables is a necessary device. Further, when the processing operation is performed, a large amount of dust is raised in the air, so that the health of operators is endangered, and therefore, the existing working trolley is provided with a dust collector and the like, so that the operators can increase the convenience of the work during the processing operation, and can maintain the health of the operators at the same time.
The existing working trolleys can be roughly divided into the following categories according to the structural configuration mode, wherein wheels are directly arranged at the bottom of the dust collector, the dust collector is placed on the working trolleys, and the internal system of the dust collector is directly combined with the working trolleys. First, a working cart of the type in which wheels are directly attached to the bottom of the cleaner is described, such as Mobile Dust Extractor CTL E AC CLEANTEX, mobile VacuumCleaner CTM E and WCR 1000WORK CENTRE from FESTOOL, dust extract 1025L PC 230V from MIRKA and MOBILE 35260 EN from RUPES, which provide the technical teaching of the removability of the cleaner, but which require the removal of the power cord, compressed air tube, dust tube, housing and cleaner one by one to replace the Dust collection tub, so that the cleaner can be opened to replace the Dust collection tub. Furthermore, this type of work trolley is not provided with a work platform, which is inconvenient for the operator to place the machine tool during the work.
On the other hand, the type in which the vacuum cleaner is directly placed on the work cart is shown in Trolley for dust extractor of chinese patent No. CN207786208U, MIRKA, MULTIPURPOSE TROLLEY FOR PROFESSIONAL VACUUN CLEANERS of RUPES, and the like. In view of the foregoing, it has been found that this type of work cart is of the type in which the vacuum cleaner is additionally placed on the work cart, with the vacuum system obviously not being integrated with the work cart. Because the dust collector and the working trolley are respectively provided with the shell and other structures, when the dust collector is taken into the working trolley, only the shell of the working trolley can play a role in protecting the internal device, and the shell of the dust collector cannot function, so that the shell of the dust collector is similar to a dummy shell, and the cost of the working trolley is increased. In addition, when the dust collection barrel is replaced, the dust collection barrel can be taken out only by detaching the dust collector from the working cart and then sequentially detaching the structure on the dust collector, so that the dust collection barrel is inconvenient for operators to replace.

Referring to fig. 1 to 5, the present invention provides a working cart 100 with a dust collection system, wherein the working cart 100 comprises a dust collection system 10 and a cart body 20, and the dust collection system 10 comprises a cyclone dust separating device 11, an air suction motor 12, an air pipe 13 and a dust storage barrel 14. Specifically, the cyclone dust separating apparatus 11 is connected to the suction motor 12 through the air pipe 13, the cyclone dust separating apparatus 11 has an air inlet 111 connected to the outside, and the cyclone dust separating apparatus 11 is acted by the suction motor 12 when the suction motor 12 is started, so that the air inlet 111 sucks a dust airflow to be filtered 70, and the dust airflow to be filtered 70 is introduced into the dust collecting system 10 for dust separation. In addition, the suction motor 12 used in the present invention is a motor that can be used in a dry and wet environment, so the dust airflow 70 to be filtered extracted by the cyclone dust separating apparatus 11 can be a humid air or an air containing less moisture (commonly called dry air). In one embodiment, the air suction motor 12 includes an electric motor 121 and a wind barrel 122 connected to the electric motor 121, and when the electric motor 121 is started, air is sucked into the wind barrel 122 by a wind inlet side 123, so that the air is converted into a high pressure air flow 74 by the wind barrel 122, and then the high pressure air flow 74 is discharged toward the direction facing the electric motor 121 and simultaneously dissipates heat of the electric motor 121. In addition, the suction motor 12 is stably assembled on the cart body 20, the suction motor 12 includes at least one auxiliary support bar 124 connected to the air tub 122, and each auxiliary support bar 124 is located outside the suction motor 12, thereby fixing the suction motor 12 on the cart body 20. On the other hand, the air pipe 13 has an air inlet end 131 connected to the cyclonic dust separation device 11 and an air outlet end 132 connected to the air inlet side 123 of the suction motor 12, and the air inlet end 131 receives the air flow exhausted from the cyclonic dust separation device 11 and enables the air flow in the air pipe 13 to flow from the air outlet end 132 toward the air inlet side 123 of the suction motor 12, which will be described in detail later. In addition, the dust storage barrel 14 is disposed below the cyclone dust separating apparatus 11, and the dust storage barrel 14 is configured to receive a dust 80 filtered by the cyclone dust separating apparatus 11 from the dust airflow 70 to be filtered.
On the other hand, the cart body 20 of the present invention is provided for the dust collection system 10 to be disposed therein, and the cart body 20 has a frame 21, an assembling space 22 defined by the frame 21, and a carrier plate 23 disposed in the assembling space 22 and connected to the frame 21. The frame 21 includes a plurality of wheels 211 respectively disposed at the bottom and a cart handle 212. The support plate 23 is horizontally disposed in the assembly space 22, so that the support plate 23 divides the assembly space 22 into a top area 221 and a bottom area 222, the top area 221 is provided for the cyclone dust separating device 11 and the suction motor 12 to be disposed thereon, the bottom area 222 is provided for the dust storage barrel 14, and the height of the top area 221 and the height of the bottom area 222 can be adjusted according to the size of the internal device. Further, the carrier plate 23 has a through hole 231, wherein the through hole 231 is disposed corresponding to a dust outlet 112 of the cyclone dust separating device 11 on a side facing the top region 221, and the through hole 231 is disposed corresponding to an opening 141 of the dust storage barrel 14 on a side facing the bottom region 222, i.e. the through hole 231 is used for communicating the cyclone dust separating device 11 with the dust storage barrel 14.
Next, referring back to fig. 3 to 5, an embodiment of the working cart 100 will now be described. It is first assumed that the work cart 100 of the present invention does not initially begin the machining operation, i.e., the suction motor 12 does not begin to operate. When the suction motor 12 is controlled to start operating, the suction motor 12 draws the dust-to-be-filtered air flow 70 containing the dust 80 to the outside through the cyclone dust separating apparatus 11. After the dust airflow 70 to be filtered enters the cyclone dust separating device 11 through the air inlet 111, the dust airflow 70 to be filtered forms a descending cyclone 71 along the inner wall of the cyclone dust separating device 11, and because the pipe diameter of the cyclone dust separating device 11 is gradually reduced, the rotation speed of the descending cyclone 71 is gradually increased in the descending process, and the dust 80 is centrifugally moved to the outer edge of the descending cyclone 71, and then the dust 80 is moved along the inner wall of the cyclone dust separating device 11 along the descending cyclone 71 towards the direction facing the dust storage barrel 14 through the through holes 231. Then, when the descending cyclone 71 is moved to the position in the dust storage barrel 14, the rotational speed of the descending cyclone 71 is reduced due to the pipe diameter of the dust storage barrel 14 being larger than that of the cyclone dust separating apparatus 11, and the dust 80 is centrifugally deposited in the dust storage barrel 14, and the descending cyclone 71 is converted into an ascending cyclone 72 by the air suction motor 12. The rising cyclone 72 is then displaced towards the suction motor 12 to become a relatively clean dust separated air flow 73, and the dust separated air flow 73 enters the air tub 122 of the suction motor 12 along the air pipe 13, and the dust separated air flow 73 is pressurized by the air tub 122 to be converted into the high pressure air flow 74. The high-pressure air flow 74 is guided by the air tub 122, so that the high-pressure air flow 74 flows towards the direction facing the electric motor 121, the high-pressure air flow 74 is discharged out of the air tub 122 to be converted into a heat dissipation air flow 75, and the heat dissipation air flow 75 dissipates heat of the electric motor 121 while discharging the air suction motor 12.
Therefore, compared with the prior art, the invention breaks through the nest socket of the old working cart, namely the dust collection system 10 is directly combined with the cart body 20, so that the dust collection system 10 has a simpler structure. In addition, the dust storage barrel 14 of the present invention has the characteristic of being detachable independently, so that the operator does not need to detach other components when replacing the dust storage barrel 14, thereby facilitating the replacement of the operator. In addition, the working cart 100 of the present invention is implemented with a hand machine tool 200, and the hand machine tool 200 may be an electric hand machine tool (not shown) or a pneumatic hand machine tool (not shown).

On the other hand, in one embodiment, the dust collection system 10 includes a high efficiency air particulate filter (HEPA) 15 disposed between the cyclonic dust separation device 11 and the suction motor 12, the high efficiency air particulate filter 15 is in communication with the channel 133 and is located in front of the suction motor 12, the high efficiency air particulate filter 15 receives the dust separated air flow 73 from the cyclonic dust separation device 11, and intercepts the fine dust 80 contained in the dust separated air flow 73, so that the dust separated air flow 73 passing through the high efficiency air particulate filter 15 can be cleaner. In one embodiment, the high-efficiency air microparticle filter 15 has a filtration efficiency of 90% or more. Further, the dust collection system 10 may further comprise an air duct 16 connecting the high efficiency air particulate filter 15 and the cyclonic dust separation apparatus 11.
