Abstract
The invention relates to the technical field of knocking hammers, in particular to a pneumatic knocking hammer. The pneumatic knocking hammer comprises a magnetic piston, a base plate, a knocking plate, a spring and a three-way valve. The magnetic piston, the spring and the base plate are arranged in the pneumatic knocking hammer, the magnetic piston is arranged below the base plate, the magnetic piston is connected with the spring, the base plate is connected with the three-way valve, the knocking plate is arranged at the bottom of the pneumatic knocking hammer, and an air hole is arranged at one end of the pneumatic knocking hammer above the knocking plate. The pneumatic knocking hammer is simple in whole structure and convenient to use, the knocking plate in the whole structure is thickened, equipment is protected, damage to the equipment is reduced, and work efficiency is improved.
Description
Technical field
The present invention relates to a kind of hammer that knocks, relate in particular to a kind of pneumatic hammer that knocks.
Background technology
The pneumatic hammer that knocks is to be power through compressed air, and abrupt release promotes inner tup and hits the bottom, and powerful impulse force is passed to the hopper wall, and the arch bridge that breaks up material effectively and constituted makes buildup loosening, reaches and unloads ash purpose smoothly.Traditional knocking is to use hopper wall vibrator, and the arch bridge that the vibration of utilization high-frequency often can not make material form is damaged, and be on the contrary that the material vibration is more closely knit, do not reach and unload ash purpose smoothly.Vibration intensity and frequency can not be regulated simultaneously, and high-frequency vibration is very serious for the ash bucket destructiveness, and it is strong to cause grey headwall to shake, and snaps.
Summary of the invention
The technical problem that the present invention will solve is: traditional knocking is to use hopper wall vibrator, and the arch bridge that the vibration of utilization high-frequency often can not make material form is damaged, and be on the contrary that the material vibration is more closely knit, do not reach and unload ash purpose smoothly.Vibration intensity and frequency can not be regulated simultaneously, and high-frequency vibration is very serious for the ash bucket destructiveness, and it is strong to cause grey headwall to shake, and snaps, and a kind of pneumatic hammer that knocks is provided.
In order to overcome the defective that exists in the background technology; The technical solution adopted for the present invention to solve the technical problems is: this pneumatic hammer that knocks comprises that magnetic piston, substrate, tapping board, spring and triple valve, said magnetic piston, spring and substrate place pneumatic knocking in the hammer, and substrate has magnetic piston; Magnetic piston connects spring; Substrate connects triple valve, and the pneumatic hammer bottom of knocking is provided with tapping board, and the top that a pneumatic end that knocks hammer is positioned at tapping board is provided with pore.
According to another embodiment of the invention, comprise further in the said magnetic piston being provided with magnet that both sides are provided with piston ring and O type ring in the magnetic piston.
The invention has the beneficial effects as follows: this pneumatic tapping board thickening of knocking in the hammer overall structure, protected equipment like this, reduce destruction to equipment, improved operating efficiency, and following advantage is arranged: 1, magnetic impact is big, and the powder that falls is effective; 2, knocking blanking time can adjust; 3, simple in structure, convenient disassembly; 4, reliable in quality, fault reduces; 5, low, the good energy-conserving effect of operating cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention;
Wherein: 1, magnetic piston, 2, substrate, 3, tapping board, 4, spring, 5, triple valve, 6, pore.
The specific embodiment
Fig. 1 is a structural representation of the present invention; Comprise magnetic piston 1, substrate 2, tapping board 3, spring 4, triple valve 5 and pore 6 among the figure, said magnetic piston 1, spring 4 and substrate 2 place pneumatic knocking in the hammer, and substrate 2 has magnetic piston 1; Magnetic piston 1 connects spring 4; Substrate 2 connects triple valve 5, and the pneumatic hammer bottom of knocking is provided with tapping board 3, and the top that a pneumatic end that knocks hammer is positioned at tapping board 3 is provided with pore 6.
Be provided with magnet 7 in the said magnetic piston 1, both sides are provided with piston ring 8 and O type ring 9 in the magnetic piston 1.
Do not feed under the compressed-air actuated state at the pneumatic hammer that knocks, magnetic piston 1 is close on the substrate 2 by strong magnetic force; When connecting triple valve 5, compressed air flows into pneumatic knocking in the hammer body, pneumatic increased pressure of knocking in the hammer body; When greater than magnetic force, make magnetic piston 1 break away from substrate 2 at a high speed, because the reaction force of strong magnetic force produces very strong counteragent, the magnetic piston 1 bump pedestal that falls at a high speed; Its impulsive force is passed to feed bin, and strong wallop has played the effect that falls to adhering to powder of sweeping, during the triple valve outage; The pneumatic compressed air that knocks in the hammer body is got rid of through triple valve; So slowly rise again near substrate 2 by return spring 4 magnetic piston 1, connect airtight on substrate 2 through magnetic force, return to original state.Like this, an impact stroke is just accomplished.Through regulating the time relay in the electric control box, can reduce or strengthen and knock blanking time and knock the time.
This pneumatic hammer overall structure of knocking is simple, easy to use, and equipment has been protected in the tapping board thickening in the overall structure like this, reduces the destruction to equipment, has improved operating efficiency.
