Description
Technical Field
The invention belongs to the technical field of negative pressure lifting, and particularly relates to a high-efficiency strong-suction negative pressure lifting device.
Background
At present, the suction sweeping machines at home and abroad are mainly divided into two main types of mechanical sweeping and suction sweeping.
In the running process of the high-speed sweeper, the large sweeping disc and the small sweeping disc sweep garbage in the sweeping range into the sweeper, the rubber strip is arranged at the bottom of the middle baffle, and the rubber strip is in contact with the ground, so that the garbage swept by the large sweeping disc and the small sweeping disc is prevented from flying out of the sweeping range of the sweeper from the opposite side due to inertia. Along with the advancing of sweeping the floor car, after sweep the roller after with rubbish contact, sweep the roller after the high-speed rotation of roller and upwards throw the rubbish and send on the conveyer belt, the bottom baffle then is between conveyer belt and sweep the roller after, lets the material carry to the conveyer belt smoothly, and the conveyer belt carries the material to the dustbin again, accomplishes the cleaning work.
On the basis of the original structure, the sweeping roller capable of automatically adjusting the height of the rear sweeping roller according to the road surface condition is arranged, the working principle is that a lifting hydraulic cylinder is arranged between a frame and a positioning rod, the included angle between the positioning rod and the frame is controlled, an adjusting spring is arranged between a movable rod and a spring frame, when the road surface is uneven, the rear sweeping roller moves upwards to drive the movable rod to rotate around a hinge shaft between the movable rod and the positioning rod, but the position of the positioning rod is controlled by the hydraulic cylinder, so that the included angle between the positioning rod and the frame is unchanged, the spring is compressed after being stressed, elasticity is generated, the pressure born by the sweeping roller when being contacted with the ground is ensured to be maintained in a certain range, and the height of the sweeping roller is adjusted according to the height of the road surface.
The movable rod can rotate around the hinge shaft between the movable rod and the positioning rod, but the limiting clamping plate stretches into the inner side of the movable rod, so that the movable rod cannot move downwards, and therefore the movable rod and the rear sweeping roller arranged on the movable rod can only rotate upwards around the hinge shaft between the movable rod and the positioning rod.
The problems with mechanical cleaning devices are mainly:
(1) the rolling brush is easy to break down, and when an elongated object or a flexible object is cleaned, garbage is easy to wind on the rolling brush;
(2) the small particle garbage cannot be cleaned, the contact area between the small particle garbage and the rolling brush is small, and the small particle garbage is not easy to be thrown by the rolling brush during working, so that the problem that the small particle garbage cannot be thrown into the conveyor belt easily occurs;
(3) the dust is larger, secondary pollution exists, and the dust is easily influenced by factors such as external air flow and the like in the cleaning process, so that dust emission is generated, and secondary pollution is caused; the maintenance and maintenance difficulty of the back sweeping roller is high, and the service life of the back sweeping roller is not long.
The suction sweeping type road sweeper mainly forms negative pressure in the suction sweeping device through a negative pressure fan, so that garbage is sucked into the dustbin. When the vacuum cleaner works, the large sweeping disc and the small sweeping disc sweep garbage in a working area to the bottom of the vehicle, the middle baffle is arranged in the middle of the vehicle, the garbage is prevented from flying out from the other side after passing through the bottom of the vehicle, and along with the advancing of the vehicle, the garbage enters the suction sweeping port of the suction sweeping device and is sucked into the garbage collection box under the negative pressure condition generated by the negative pressure fan, so that the suction sweeping work is completed.
The suction-sweeping type cleaning device has the following main problems:
(1) the negative pressure fan of the suction sweeping type cleaning device has high cost and power consumption, and the auxiliary engine is required to be installed, so that the production cost and the use cost are high.
(2) The large garbage or the slender garbage is difficult to clean, the large garbage can be sucked up by the aid of higher negative pressure, and if the power of the fan is low, the problem of incapacity of sucking up is easy to occur. For long-strip-shaped garbage, the cross section of the air duct of the suction sweeping type cleaning device is mainly circular, so that the long-strip-shaped garbage cannot smoothly enter from the suction inlet, the problem that materials stay at the suction inlet is easily caused, and the subsequent suction sweeping work is influenced.
(3) When the airflow channel is blocked, the airflow channel cannot be automatically treated, and when the airflow channel is blocked, the problem of blocking is solved by adopting manpower after stopping, so that the working efficiency and the safety are reduced.
(4) In rainy and snowy weather, the suction sweeping type cleaning device can suck more rain and snow, so that dumping of garbage is affected, the total weight of materials is increased, and power consumption is increased.
Whether it is a mechanical cleaning device or a suction cleaning device, the following problems exist:
(1) when the device works, two devices cannot select proper working parameters to clean according to the types and the amounts of garbage existing on the road surface, and in order to ensure the working quality, the cleaning operation needs to be completed with larger power, but the road surface without garbage can cause larger resource waste and increase the operation cost.
(2) In special weather and external environments such as rain, snow, sand and dust, low temperature, etc., the characteristics of the road surface, the garbage and the cleaning device are changed, and proper working parameters are required to be selected according to the external environment conditions, but the existing device has no working modes under different external environment conditions, so that the cleaning quality under the special conditions is reduced.

The ability of the second telescoping rod 46 to impart a return to the side plates 44, after the barrier no longer compresses the return spring 48, the tension spring ensures that the second telescoping rod 46 always contacts the alignment slot 50 until the two side plates 44 are fully retracted and proximate the slide bar 49; the slide rod 49 has a limited sliding range and does not disengage from the slide groove 40.
The working principle of the invention is as follows:
in the initial state, the return spring 48 is in a compressed state, the extension spring is in an extended state, and the control spring 41 is in a natural state; the link 42 and the slide bar 49 are partially retracted within the working space 32;
the invention is matched with a road suction sweeper, the road suction sweeper is provided with a dustbin, and when the dustbin cover of the dustbin is closed, only one inlet is communicated with the connecting pipeline 13 and matched with the impurity outlet 21; the invention combines the traditional mechanical cleaning device with the suction cleaning device, and the suction cleaning device is used for treating the garbage with light mass and small volume and cleaning the garbage with large mass and large volume;
the road suction sweeper advances, a motor (not shown) for controlling the turbine in the volute 11 to rotate is started, one side of the dustbin is closed, negative pressure is formed on one side of the connecting pipeline 13, the lifting pipeline 20 and the rotating shaft 26, a soft blocking curtain is arranged on one side of the ground pasting frame 16, which faces the advance of the road suction sweeper, garbage is allowed to pass through, and after the garbage enters the ground pasting frame 16, the garbage tends to be lifted; the light garbage can be directly sucked up, such as paper scraps, leaves and the like;
when the driving motor is started to drive the conveying belt 29 to rotate and the garbage in the ground pasting frame 16 contacts the rotating conveying belt 29, the garbage can move along with the lifting plate 22 on the conveying belt 29 to be lifted, the conveying belt 29 rotates anticlockwise under the view of fig. 4, and the garbage is lifted from the right side of the conveying belt 29; the heavy garbage in the state can be lifted, such as branches, small broken stones and the like;
in the above process, the moving motor is started in a matched manner to drive the rotating shaft 26 to rotate, the rear sweeping roller 25 rotates along with the rotating shaft 26, and the rotating shaft 26 rotates clockwise to lift the garbage on the left side of the rotating shaft under the view of fig. 4, so that the garbage is easier to contact the conveying belt 29; thereby reduce turbo fan's consumption, turbo fan need not very high power and can realize promoting and collecting rubbish, and when rubbish was promoted to the spiral case 11 under, rubbish fell into the dustbin from miscellaneous mouthful 21, and the dustbin is not the structure of cavitation nothing, is equipped with a plurality of guide boards in the dustbin, can prevent that the rubbish that falls into the dustbin from being sucked away.
In addition, the control hub in the road suction sweeper can detect the running state of the conveyor belt 29 (a motor rotation speed sensor and conventional technical means), when the running state deviation of the conveyor belt 29 is too large (the condition that the conveyor belt 29 is not completely blocked and cannot rotate, if the conveyor belt 29 is completely blocked, the condition that the conveyor belt 29 is completely blocked is required to stop working for maintenance, and the condition that the conveyor belt 29 is difficult to happen is that garbage which can enter the floor frame 16 is firstly judged subjectively by the naked eyes of a driver, then a baffle in front of the rotating shaft 26 carries out objective screening, and at the moment, the garbage which can enter the lifting pipeline 20 does not have large garbage with too-discrete spectrum); at this time, there is a possibility that the negative pressure air duct (the inner space of the lifting pipe 20) is blocked, and the barrier removal cylinder 31 is started regardless of whether the actual situation is blocked; the obstacle clearing cylinder 31 is specifically a hydraulic cylinder, and a conventional driving device comprises a cylinder barrel and a piston rod, after the obstacle clearing cylinder 31 is started, the piston rod extends out relative to the cylinder barrel, the piston rod drives the bearing rod 45, the sliding rod 49, the side plate 44 and the obstacle clearing head 27 to extend out together and penetrate through the sealing plate 28, after the obstacle clearing head 27 contacts with the blockage, the blockage is pushed to change the original blockage state, so that the length direction (the approximate direction (such as the direction that the blockage is pushed to be in a straight state by the obstacle clearing head 27 after the branches vertically entering the lifting pipeline 20 are blocked) is forced to be parallel to the axis of the bearing rod 45 (the blockage is generally irregular, the contact point between the obstacle clearing head 27 and the blockage is small, and the obstacle clearing head 27 cannot push the blockage to be straight under the trend that the conveying belt 29 continuously rotates); thereby solving the problem of blockage;
if the blockage is serious, the object cannot be pushed after the obstacle clearance head 27 contacts the blocked object, the obstacle clearance cylinder 31 is continuously started after the obstacle clearance head 27 contacts the blocked object, the piston rod of the obstacle clearance cylinder 31 continues to extend, the obstacle clearance head 27 cannot move at the moment, but the bearing rod 45 can move, the reset spring 48 is compressed, the sliding rod 49 and the bearing rod 45 slide relatively, in the process, the alignment groove 50 at the end part of the bearing rod 45 is propped against the second telescopic rod 46, the second telescopic rod 46 is forced to move and stretch, the stretching spring in the second telescopic rod 46 is further stretched, the two side plates 44 are gradually stretched under the action of the connecting rod 42, and the two side plates 44 still move along with the bearing rod 45 in the process that the two side plates 44 are gradually stretched; referring to fig. 9 and 10, the state of the two side plates 44 changes, and at this time, the two side plates 44 scatter the plugs (for example, in rainy weather, the leaves that are clustered on the surface of the conveyor belt 29 can be smoothly lifted after being scattered by the two side plates 44);
in addition, when the blockage occurs, if the obstacle clearance head 27 abuts against the lifting plate 22 when the obstacle clearance head 27 pushes the blockage in advance, the obstacle clearance head 27 cannot move continuously, and the two side plates 44 are opened; the lifting plate 22 is made of hard rubber, and is allowed to bend along the lifting direction of garbage, when the two side plates 44 are unfolded (two sides of the lifting plate 22 which are respectively abutted by the barrier removing heads 27), after one lifting plate 22 which is abutted by the barrier removing heads 27 contacts with one side plate 44 at the lower side after the lifting plate moves, the lifting plate is forced to bend, so that the lifting plate smoothly passes through the bearing rod 45, and then under the action of the reset spring 48 and the extension spring, the two side plates 44 are reset, and the states of the sliding rod 49 and the bearing rod 45 are reset; at this point the head 27 can then be extended normally to contact the obstruction.
It should be noted that, when the plurality of obstacle clearing cylinders 31 are operated simultaneously, they do not interfere with each other, and even if the blockage is pushed to the leftmost side of the conveyor belt 29, the negative pressure lifting operation of the present invention is not affected as long as the conveyor belt 29 does not stop rotating, but only the power consumption of the turbo fan needs to be increased, and when the blockage is resolved, the power consumption of the turbo fan can be reduced immediately.
The principle of operation of the placement box 18: the lifting cylinder 35 can adjust the overall height of the back-sweeping roller 25, when the working environment is changed, in order to adapt to the gradient of a road, the height of the back-sweeping roller 25 is adjusted to a proper position, the first telescopic rod 37 can adjust the height of the back-sweeping roller 25 to be passively adjusted, and when the road jolts, the back-sweeping roller 25 can be always in good contact with the ground through the first telescopic rod 37, so that small garbage is prevented from being missed; in addition, the installation position of the volute 11 is not limited to the top of the connecting pipeline 13, and can be preferably the side surface of the connecting pipeline 13, so that the situation that garbage blocks the filter plate 12 can be effectively reduced.
