As depicted in figs. 1 and 2, the overall construction of quartering hammer is formed by outer housing 1 and the mutually socket of inner housing 2, Ke Yitong It crosses and inner housing 2 is entrenched in outer housing 1, then motor 4 is fixedly mounted on outer housing 1, and the output end of motor 4 is stretched It is fixed in inner housing 2 to be rotatablely equipped with cam rotation mechanism 3, the both ends difference of cam rotation mechanism 3 into inside inner housing 2 It is rotatably installed on the side wall of inner housing 2, drives cam rotation mechanism 3 to be rotated by motor 4, in cam rotation mechanism 3 End be hinged with driving member 5, thus driving member 5 is done moves up and down, and by pick rod 6 be mounted on driving member 5 lower section, The pick rod 6 of underface is formed when driving member 5 does movement up and down and is tapped, pick rod 6 is forced to do high frequency under percussion effect The vibration of rate and object is tapped, the recoil strength generated after percussion can force pick rod 6 to pop up, and push driving member at this time 5, so that the anti-cam 31 that pushes away of driving member 5 is carried out next step rotation, this makes it possible to well dissolve recoil strength and absorb into dynamic Can, it is energy saving to have the function that.

As shown in Figure 3 and Figure 6, the present invention in cam rotation mechanism 3 be by cam 31, cam matrix on be arranged it is convex It plays 32 to be made, one end of cam 31 is connected on the side wall of inner housing 2, and the other end is fixedly connected with bevel gear 32, bevel gear 32 On the side wall of inner housing 2, the output end of motor 4 puts in inner housing 2 and is engaged with bevel gear 32, in this way the biography in motor 4 Under action is used, bevel gear 32 rotates, and bevel gear 32 is rotated in the high-speed drive lower band moving cam 31 of motor 4, is mounted on connecting rod 33 The driving member 5 of end is just tapped the upper underdrive for doing high frequency by the protrusion 32 of cam 31, and protrusion 32 is at least provided with two certainly It is a, it two protrusions 32 and is evenly distributed on the side wall of matrix, naturally it is also possible to be provided with multiple, while protrusion 32 is integrally formed In on matrix, such internal structure is stablized, and is less likely to occur to be broken when tapping driving member 5, at the same time not by cam 31 Ovalisation either other shapes are set, but cam 31 is arranged to cylindrical matrix and is on the side wall of matrix It is integrally formed protrusion 32, in rotation, raised 32 are capable of sudden being formed to driving member 5 hits such cam 31, so as to Enough driving member 5 is driven to vibrate, and after the completion of vibration, protrusion 32 is detached from rapidly driving member 5, at this time driving member 5 and pick rod 6 By object recoil strength when, driving member 5 counter in time can push away cam 31, make cam 31 enter next round rotation strike step Suddenly.

Simultaneously as shown in Figure 2 and Figure 7, it is also equipped with locating part 7 on inner housing 2, shows locating part 7 by left and right two in figure Part forms, and two locating parts 7 in left and right are stitched together, and centre is formed with open slot 71, and the upper part of open slot 71 is for pick rod 6 Upper end stretch out, the lower part of open slot 71 is stretched out for the lower end of pick rod 6, and pick rod 6 is also formed with around its peripheral wall Step cutting pattern 61, as shown in figure 9, step cutting pattern 61 is stuck in open slot 71, the upper and lower end face of step cutting pattern 61 is limited at this time In open slot 71, when pick rod 6 does vibration, upper and lower end face of the step cutting pattern 61 constantly with open slot 71 contradicts, because One is formed for step cutting pattern 61 and pick rod 6, internal structure is stablized, it is not easy to it is broken during vibration, and with Contact area is big during the upper and lower end face of open slot 71 contradicts, uniform force.

Certainly, also it is installed with guide sleeve 8 in the lower end of outer housing 1, the structure of guide sleeve 8 is as shown in figure 8, i.e. guide sleeve 8 The end and outer housing 1 for being supported on outer housing 1 push against, while limit hole 81 is offered in guide sleeve 8, the size of limit hole 81 and pick The diameter of pricker 6 is identical, i.e., pick rod 6 can be stretched out from limit hole 81 just, to prevent the rolling in 6 occurred level direction of pick rod It is dynamic, while antifriction metal (AFM) alloy is also welded on the inner wall of limit hole 81, when pick rod 6 moves up and down with 81 wall of limit hole On alloy rub, the wearability of alloy is it is possible to prevente effectively from the aperture of limit hole 81 becomes larger.

When mounted, can be as shown in Figures 3 and 5, motor 4 is fixedly mounted on cover board 11, the lid of cover board 11 is closed in shell The upper end of body 1, motor 4 is located inside outer housing 1 at this time, because quartering hammer at work, needs the vibration of high frequency, and at this time Motor 4 is arranged on outer housing 1, and on inner housing 2, inner housing 2 can opposite shell body 1 for the main part for generating vibration It vibrates, but not outer housing 1 is driven to vibrate, therefore when motor 4 is on outer housing 1 is just not easy to damage because of vibration Bad, at the same time, motor 4 is located inside outer housing 1, it is possible to prevente effectively from the environment that extraneous dust or wind rain shines is dry It disturbs, and the noise that motor 4 generates can be also isolated.

It is slow by being arranged between outer housing 1 and inner housing 2 in order to further decrease the vibration of element inside inner housing 2 Elastic component 9 is rushed, as shown in figure 4, can be compressed spring, rubber air spring can also be used, pass through subtracting for snubber elastomeric part 9 Shake acts on, and reduces inner housing 2 and the Oscillation Amplitude of its internal element, ensures that reduction damages consumption in the operating condition, to Improve vibration efficiency.

In actual mechanical process, while finding when cam 31 to be mounted on inner housing 2, the friction with inner housing 2 Resistance is larger, and when being mounted between inner housing 2 and cam 31 using ball bearing, rotating speed can obtain certain raising, but Or the requirement of high frequency can not be met well, unless using special bearing, but the cost is relatively high, therefore using several A small bearing 10 all takes out the inside retainer of small bearing 10 to substitute big ball bearing, and then increases Ball number increases the bearing capacity of bearing 10, this makes it possible to make the rotating speed of cam reach 3000 ~ 5000 rpms, in this way High-frequency vibration under, the higher material of toughness can also be smashed by easy.

Simultaneously in order to further prevent quartering hammer effected by environmental factors at work, inner housing 2 is arranged to Hermetically sealed shape, and lubricating oil is filled in inner housing 2, only there are the through-holes stretched into up to output end for horse 4, and motor 4 is stretched Also be sealed closing after entering through-hole, in this way setting be quartering hammer at work, be easy extraneous dust and be shattered Particulate matter enters in inner housing 2 and causes to damage to the drive mechanism in inner housing 2, simultaneously as the mechanism in inner housing 2 turns Speed is very fast, it is therefore desirable to which injection lubricating oil is lubricated in inner housing 2, carries out forming cooling to transmission while lubrication Effect ensures that quartering hammer can be worked for a long time, and can prevent extraneous dust impurity from entering in inner housing 2 It is destroyed, this makes it possible to ensure effectively using for a long time for quartering hammer.

And when being installed to the quartering hammer on shatter machine, while the operating system of shatter machine carries out accurately quartering hammer Manipulation, it will be able to easily efficiently adapt to quartering hammer progress vibration and work, the quartering hammer is efficient at work, generates Amplitude it is small, low noise will not feel that seismaesthesia is strong positioned at indoor operating personnel are operated, and noise is big, can be effectively increased this The practicability of shatter machine.
