The utility model is achieved through the following technical solutions:
Environment protection dust suction eraser, comprise front deck and rear deck, described front deck front end is provided with arranges net, described front deck and rear deck separate by dividing plate, described rear deck rear portion is provided with sucker, between described front deck and rear deck, be provided with wind wheel apparatus, described wind wheel apparatus comprises fan, described fan is placed in the hole on dividing plate, described fan is fixed on blower tray by fan spindle, described fan spindle front end fixed cover is connected to columniform gear, described gear one side is provided with the screw rod be meshed with gear, described screw front end is fixed with the screw rod chain wheel, described screw rod chain wheel front end is provided with the power transmission shaft chain wheel fastened with it, described power transmission shaft chain wheel is fixed on power transmission shaft one end, described power transmission shaft other end fixed cover is connected to rubber wheel, described spiro rod rear end connecting screw rod axle, described screw shaft is provided with the ring-shaped step of a protrusion, between the ring-shaped step of described spiro rod rear end and screw shaft, be provided with spring, in the rotating hole be arranged on support of described screw shaft.
Described front deck is pre-large post-small train of dress formula front deck.
Described rear deck rear portion is provided with close net.
Described rear deck one side is provided with rear hatchcover.
Described wind wheel apparatus is 2, and described 2 wind wheel apparatus symmetries are arranged side by side.
Described rear deck rear portion is provided with two close nets, corresponding with the position of two fans of described wind wheel apparatus respectively.
The utility model has the following advantages compared to existing technology:
The environment protection dust suction eraser that the utility model provides, its unique wind wheel apparatus adopts frictional resistance to make the rubber wheel rotation come drive fan to rotate as power and produces negative pressure, thereby utilize supplemental air flow to carry dust secretly and realize dust-absorbing function, without any electric power, drive, battery pollution and noise pollution have been reduced, energy-conserving and environment-protective.The close net that its rear deck rear portion arranges has played the effect of emptying vapour lock dust, and the dust centralized collection, to rear deck, is run up to a certain amount of the time to the rear hatchcover of opening on rear deck it is poured out, non-secondary pollution, easy for operation.Adopt two desk fans, its power is stronger, and pick-up performance is more obvious.Simultaneously, the rear deck rear portion is provided with sucker, and the used time can not inhaled blackboard eraser can not fall down on blackboard, convenient and practical.In addition, its front deck is the train of dress formula, has prevented that dust from missing between blackboard and blackboard eraser, has improved the service efficiency of blackboard eraser.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is wind wheel apparatus structural representation of the present utility model.
The specific embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Referring to Fig. 1 and Fig. 2, the environment protection dust suction eraser that the utility model provides, comprise front deck 1 and rear deck 2, front deck 1 and rear deck 2 separate by dividing plate 3, front deck 1 is pre-large post-small train of dress formula, front deck 1 front end is provided with larger the arranging net of hole (scheming not shown), during use, arranges net and directly with blackboard, contacts and wipe dust.Rear deck 2 rear portions are provided with sucker (scheming not shown), and rear deck 2 rear portions are provided with close net 21 to play the effect of emptying vapour lock dust, and rear deck 2 one sides are provided with openable rear hatchcover 22.Between front deck 1 and rear deck 2, be provided with wind wheel apparatus, wind wheel apparatus comprises fan 31, fan 31 is placed in the hole on dividing plate 3, fan 31 is fixed on blower tray 312 by fan spindle 32, fan spindle 32 front end fixed covers are connected to columniform gear 33, gear 33 1 sides are provided with the screw rod 34 be meshed with gear 33, screw rod 34 front ends are fixed with screw rod chain wheel 35, screw rod chain wheel 35 front ends are provided with the power transmission shaft chain wheel 36 fastened with it, power transmission shaft chain wheel 36 is fixed on power transmission shaft 37 1 ends, power transmission shaft 37 other end fixed covers are connected to rubber wheel 38, screw rod 34 rear end connecting screw rod axles 39, screw shaft 39 is provided with the ring-shaped step 391 of a protrusion, between the ring-shaped step 391 of screw rod 39 rear ends and screw shaft 39, be provided with spring 310, in the rotating hole be arranged on support 311 of screw shaft 39.When rubber wheel 38 rotated toward the direction, screw rod chain wheel 35 can engage with power transmission shaft chain wheel 36, thereby now screw rod 39 can be driven in rotation 31 rotations of drive fan; When rubber wheel 38 opposite spin, screw rod chain wheel 35 just can not engage with power transmission shaft chain wheel 36, is in released state, and now screw rod 39 can not be driven in rotation, and fan 31 just can not rotate yet.Above-mentioned wind wheel apparatus is two, is arranged side by side along dividing plate length direction symmetry, and rear deck 2 rear portions are provided with two close nets 21, corresponding with the position of two fans 31 respectively.
During use, when blackboard eraser moves to a direction, due to the effect of frictional resistance being arranged between rubber wheel 38 and blackboard, make rubber wheel 38 start rotation and produce power, rubber wheel 38 drive power transmission shafts 37 and on power transmission shaft chain wheel 36 rotating Vortexes, screw rod chain wheel 35 presses to power transmission shaft chain wheel 36 and engages with power transmission shaft chain wheel 36 under the effect of the spring 310 of screw rod 39 rear ends, make power transmission shaft chain wheel 36 drive screw rod chain wheel 35 and screw rod 39 synchronous rotaries, screw rod 39 drives and 33 rotations of its meshed gears again, thereby drives fan 31 rotations.Make the interior formation air-flow of front deck 1 and rear deck 2, front deck 1 is because the effect of air-flow forms low pressure, therefore the dust that is in front deck 1 can be blown to rear deck 2 from front deck 1 by external pressure, the air-flow of process rear deck 2 is directly from draining the close net 21 of rear deck 2, and dust can be blocked in rear deck 2, when dust runs up to a certain amount of the time, open rear hatchcover 22 it is poured out and gets final product.When blackboard eraser moves to opposite direction, due to screw rod chain wheel 35 can and power transmission shaft chain wheel 36 can not block and, be in released state, so fan 31 can drivenly not counter-rotate, thereby avoided fan 31 reverse rotations that dust is flow backwards.Blackboard eraser is to constantly alternating movement of both direction, screw rod chain wheel 35 also can with the continuous clutch of power transmission shaft chain wheel 36, thereby guaranteed that fan 31 rotates the effect that plays dedusting to a direction.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
