The accommodating unit 2 includes a bottom wall 21 and a surrounding wall 22 extending upward along the periphery of the bottom wall 21. The bottom wall 21 cooperates with the surrounding wall 22 to define a slag A suitable for accommodating the slag to be crushed. The groove 23 is accommodated. In general, in order to enable the storage unit 2 to be detachably engaged with the positioning portion 114 of the fixing portion 113, in this embodiment, the storage unit 2 further has an outwardly extending edge from the top edge of the surrounding wall 22. The card is wall 24. The positioning section 114 will abut against the clamping wall 24 to generate a positive force to cooperate with the surrounding wall 22 and the bottom wall 21. However, it is not limited to this structure, and it is still within the patent scope of the present invention as long as the storage unit 2 can be detachably engaged with the fixing portion 113.

It is to be noted that the effect of the accommodating unit 2 being detachably stuck to the fixing portion 113 is that the accommodating unit 2 can be replaced with the size or quantity of the slag accommodated, thereby improving the efficiency of the operation; If the storage unit 2 is worn out after a long period of use, it can be directly replaced, thereby improving the convenience of maintenance.

Referring to FIG. 2 and FIG. 3, the crushing unit 3 includes a power output member 31 extending downward from a bottom surface of the connecting portion 111, and a bottom end connected to the power output member 31 and powered by the power output member 31. The impact member 32 of the slag A is impacted. The impact member 32 is moved relative to the storage unit 2 between an impact position against the slag A as shown in FIG. 2 and a return position away from the bottom wall 21 as shown in FIG. In the impact position, the impact member 32 abuts against the slag A to generate an impact force to break the slag A. Specifically, the power output member 31 is a pneumatic cylinder or a hydraulic cylinder, but is not limited thereto. As long as the power can be output, the impact member 32 is driven relative to the storage unit 2 at the impact position and the return. Move between positions.

The impact member 32 has an impact portion 321 , a cover portion 322 extending outwardly along the top edge of the impact portion and covering the surrounding wall 22 of the storage unit 2 , and a cover portion 322 extending toward the power output member 31 . The association part 323.

Referring back to FIG. 1 , the control unit 4 can drive the power output member 31 to move the impact member 32 relative to the storage unit 2 to move back and forth between the impact position and the return position, and crush by reciprocating movement. The slag A.

The sensing unit 5 includes a position sensing member 51 for sensing the position of the impact member 32, a fixed sensing member 52 disposed at one end 1142 of the positioning portion 114 for sensing the positioning of the storage unit 2, And a door sensing member 53 disposed on the side of the housing 12 adjacent to the side opening 122 for sensing whether the cover door 123 closes the side opening 122 or not.

Referring back to Figures 2 and 3, it is considered that during the process of crushing the slag A, a huge sound may be generated, and the flying dust may cause hearing and damage to the operating personnel at the site. Therefore, when the impact member 32 is in the impact position relative to the storage unit 2, the cover portion 322 covers the storage unit 2, and the cover portion 323 stores a cover portion 322 for covering the storage unit 2 The elastic restoring power. In this way, when the impact portion 321 crushes the slag A downward, the flying dust is blocked by the covering portion 322, thereby achieving the effect of preventing dust from scattering.

In this embodiment, the cooperating portion 323 is preferably a spring 323' whose top end is fixed to the power output member 31. When the impact portion 321 crushes the slag A downward, the surrounding wall 22 of the receiving unit 2 Abutting against the covering portion 322, the upward abutting positive force compresses the spring 323', so that the spring 323' stores the elastic restoring force, so that the covering portion 322 more stably covers the receiving unit 2, thereby preventing The dust is scattered. However, it is not limited thereto, such as a device such as a pneumatic shock absorber, and the cover unit 322 may cover the storage unit 2, and the cover portion 323 stores the elasticity when the surrounding wall 22 abuts against the cover portion 322. The restoring force is further achieved to achieve the effect of preventing the dust from scattering by the covering portion 322.

Referring to FIG. 4 and FIG. 1 , since the housing 12 covers the storage unit 2 and the crushing unit 3, the noise reduction and dust blocking effect can also be achieved. In order to improve the convenience of replacing the storage unit 2 and cleaning the impact member 32, the housing 12 is provided with a side opening 122 that communicates with the accommodating space 121, and the side opening is openably closed by the cover door 123. 122, as long as the cover door 123 is opened, the user can conveniently take out the storage unit 2 from the side opening 122 and clean the impact member 32. At the same time, the powder scattered from the storage unit 2 can be collected through the dust collecting port 124, thereby achieving the effect of reducing noise and preventing dust from scattering.

Referring to FIG. 5, since the impact force of the impact member 32 is large, if the non-working state is performed during the process of replacing the storage unit 2, or during routine maintenance or the like, the control unit 4 is erroneously opened, and the impact member 32 is driven downward. In the case where the storage unit 2 is not present under the impact member 32, an accident may occur, and the impact member 32 may be directly damaged against the ground, which may cause the impact member 32 to collide with the operator. Therefore, as shown in FIG. 5, when the cover door 123 closes the side opening 122, the cover door 123 touches the door sensing member 53, and the fixing portion 115 is stuck at one end 1142 of the positioning segment 114. When the fixed sensing member 52 senses that the storage unit 2 is fixed to the fixing portion 113, that is, when the door sensing member 53 and the fixed sensing member 52 are both sensed, a common one is sent. The power is turned on to the control unit 4, and the control unit 4 must receive the start signal to activate and drive the power output member 31 to drive the impact member 32.

Referring to FIG. 6 and FIG. 1 and FIG. 3, when the slag A has been crushed, the impact member 32 is no longer abutted by the slag A, so the impact member 32 will continue to move toward the storage unit 2. The distance that the impact member 32 has moved when the slag A has been crushed will be greater than the distance that the impact member 32 has moved when the slag A has not been broken. By virtue of this characteristic, the position at which the impact member 32 has broken the slag A and moved to is set to a critical position as shown in FIG. 6, when the position sensing member 51 senses that the impact member 32 moves to the critical position. In position, the position sensing member 51 will send a closing signal to the control unit 4, causing the control unit 4 to drive the power output member 31 to move the impact member 32 to the return position as shown in FIG. With this design, when the slag A has been crushed, the control unit 4 will return the impact member 32 to the return position, and the user will no longer hear the impact sound, and the slag A can be judged to have been crushed. The work of replacing the storage unit 2 can be directly performed, and the process is intuitive and convenient.

On the other hand, the door sensing member 53 can also be regarded as another foolproof design. If the storage unit 2 is not fixed to the fixing portion 113 and the fixed sensing member 52 is damaged, the control unit 4 still receives the Starting the signal and driving the impact member 32 to move downward. When the impact member moves downward to the critical position, the position sensing member 51 still sends the closing signal to the control unit 4 to prevent the impact member 32 from continuing. A work safety problem that may occur when moving down.

After the functions of the above components are aggregated, the operation flow for crushing the slag A using the embodiment is integrated. First, the slag A is placed in the accommodating groove 23 of the accommodating unit 2, and after the storage unit 2 is locked in the fixing portion 113, the cover door 123 is closed to close the side opening 122. The fixed sensing member 52 and the door sensing component 53 confirms the induction, transmits the activation signal to the control unit 4, and the control unit 4 can be operated to drive the impact member 32 of the crushing unit 3 back and forth between the impact position and the recovery position. Moving to impact the slag A until the position sensing member 51 senses that the impact member 32 moves to the critical position, indicating that the slag A has been shredded, and the position sensing member 51 will transmit the closing signal to the control. The unit 4, the crushing unit 3 stops the crushing operation, and the user can reopen the outer cover door 123 and take out the storage unit 2 to perform subsequent processing.

In summary, the slag crusher of the present invention drives the impact unit 3 to crush the slag A accommodated in the storage unit 2, and is provided with the sensing unit 5, which will crush the slag. A's operation is automated and safety is improved, so the purpose of this new model can be achieved.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
