Further, the side hole corresponds to the compression air cavity, and is communicated with the compression air cavity when the dust filtering device moves upwards and reaches the travel limit.
The application has the following beneficial effects.
1. Because the connecting rod surface is located the position between the stopping board and has been cup jointed dust filter device connecting spring's one end and dust filter device through shaft hole complex mode activity mode fixed connection for the telescopic machine can drive dust filter device whole and remove at telescopic in-process, when dust filter device moves down to the baffle and inserts the choke groove of left gas pocket bottom, after the gas that has dust waste material got into the device from the intake pipe this moment, can't pass through left gas pocket from the below of mounting panel, thereby make the gas that has dust waste material can only pass through the filter effect of filter bag from the top of mounting panel after, enter into the below of mounting panel, when dust filter device upwards moves to the choke groove of baffle inserted left gas pocket top, through the same principle, the gas that has dust waste material can only pass through the filter effect of filter bag from the bottom of mounting panel after, this kind of method can make full use of the front and the back of filter bag, and in traditional equipment because dust gas always gets into the opposite side from one side of filter bag, lead to the filter wearing and tearing appear in one side in the long-time use course, and the filter bag condition appears in the other side state, if the filter bag to filter bag's the cost is greatly improved, the cost is greatly utilized to the filter bag that has been used to the filter bag to the problem that the filter bag has been greatly improved to the cost, the cost is greatly improved to the filter bag has been used to the cost.
2. Because the dust-containing gas can pass through the mounting plate in two ways, when the dust-containing gas passes through the filter bag from the top of the mounting plate and reaches the lower part of the mounting plate, under the action of the air flow at two sides of the mounting plate, the filter bag is enabled to be subjected to downward action and be unfolded downwards, thereby the air flow is convenient for the air flow to pass through, the whole dust filtering device is driven to move along with the operation of the telescopic machine, at the moment, the dust-containing gas passes through the filter bag from the bottom of the mounting plate and reaches the upper part of the mounting plate, the air flow directions at two sides are changed, thereby the filter bag is enabled to be subjected to upward acting force and be unfolded upwards, the filter bag is enabled to deform, the dust attached to the inner wall falls off, the inner side becomes the outer side after the filter bag is unfolded upwards, the falling dust falls to the top of the mounting plate, at the moment, the compressed air generator connected with the compressed air cavity can generate high-pressure air, the dust at the top of the mounting plate is blown into the dust discharging tube and is recovered by the dust recovering device, after the air flow direction is changed, the filter bag is unfolded downwards again, the inner side and the dust falls off from the surface of the filter bag and falls into the inside of the dust falling hopper again, thereby the dust discharging door is avoided, the mounting bracket, the filter bag is enabled to be prevented from being mounted, and the filter bag is also enabled to be deformed, and the dust is not required to be mounted at the top of each air generator.
3. When the dust that gathers on the filter bag surface is too much, can produce the effect that obstructs the air current and pass through, result in it to receive the produced effort of air current to increase, because the one end of connecting spring and the mode fixed connection of dust filter device through the joint, when result in the effect to increase, the deformation degree of connecting spring on atress one side increases, make the mounting panel constantly be close to the contact inductor, until the contact takes place, the output through the contact inductor is connected with the input of telescopic machanism through signal connection's mode after the contact, the contact inductor passes through the transmitter transmission radio signal when contact inductor and dust filter device contacts and is accepted by the telescopic machanism receiving end and stop, thereby make the telescopic machanism drive connecting rod reverse motion, drive the whole synchronous motion of dust filter device simultaneously, thereby change the air current direction of mounting panel both sides, the effect of one side clearance dust has been improved the device, simultaneously, the user can be according to specific demand, thereby change the interval between contact inductor and the mounting panel through rotating adjusting screw, thereby realize the trigger threshold value of regulation, the practicality of the device has been improved.
4. The stiffness coefficient of the connecting spring below the dust filtering device is larger than that of the connecting spring above the dust filtering device, so that the gravity of the dust filtering device can be balanced through the self elasticity of the connecting spring, the problem that the mounting plate is easy to contact with the contact sensor below and difficult to contact with the contact sensor above due to the gravity of the dust filtering device, the air flow direction is actually poor in switching, the filtering efficiency is reduced, and the stability of the dust filtering device in the use process is improved.
5. The suction hole I above the travel plate blocking plug is communicated with the suction hole I below through the suction hole II, the suction hole I below the travel plate blocking plug is communicated with the suction hole I below the suction hole II, so that when air flows from the upper side of the mounting plate to the lower side of the mounting plate, the dust filtering device is located at a position close to the lower side, the suction hole II is communicated with the suction hole I below, at the moment, the air filtered below the mounting plate is pumped out by suction generated by operation of the negative pressure machine, the air pressure difference of two sides of the mounting plate is enhanced, the air flow speed is increased, the filtering effect is further improved, and meanwhile, when the air flows from the lower side of the mounting plate to the upper side of the mounting plate, the air filtered above the mounting plate is pumped out by the suction generated by operation of the negative pressure machine, so that the effect of improving the filtering efficiency is achieved, and the practicability of the device is improved.
