[0029] In the application, the number of support plates 10 is two, two parallel and rotatable rotating rollers (not shown in the figure) are arranged between the two support plates 10, and the two rotating rollers are sleeved with a conveying belt 12, one end of one of the rotating rollers is driven to rotate intermittently under the drive of the driving assembly 20, and when it rotates intermittently, the other rotating roller is driven to rotate intermittently by the conveying belt 12, at this time the conveying belt 12 is intermittently conveyed; the cutting assembly 30 is arranged above the conveying belt 12, when the conveying belt 12 conveys the material to the lower side of the cutting assembly 30, the cutting assembly 30 cuts the material; the spraying assembly 40 is arranged at the cutting assembly 30, when the cutting assembly 30 cuts the material, the cutting assembly 30 drives the spraying assembly 40 to spray the cutting position through the triggering assembly 50, after cutting is completed, the cutting assembly 30 drives the spraying assembly 40 to stop spraying through the triggering assembly 50; the shaking box 60 is arranged on one side of the conveying belt 12, the cut material is transferred from the inlet 61 of the shaking box 60 to the inside of the shaking box 60 through the transfer assembly 13, and the shaking box 60 is used for shaking off impurities on the cut material.

[0030] The material to be cut is placed stably on the conveying belt 12, the driving assembly 20 is started, and the driving assembly 20 drives one of the rotating rollers to rotate intermittently, since the two rotating rollers are connected by the conveying belt 12, the rotating roller drives the other rotating roller to rotate synchronously intermittently through the friction of the conveying belt 12, thereby realizing the intermittent rotation of the conveying belt 12, and the conveying belt 12 conveys the material by a preset distance forward every time the intermittent rotation is completed.

[0031] When the material reaches the cutting assembly 30, the cutting assembly 30 is started to cut the material by a preset depth, at the same time, the triggering assembly 50 is triggered to send a start signal to the spraying assembly 40, the spraying assembly 40 is immediately started to accurately spray the cooling liquid to the cutting position through the spraying head 42 of a preset angle, after cutting is completed, the cutting assembly 30 is reset to send a stop signal to the spraying assembly 40 through the triggering assembly 50, the spraying assembly 40 is immediately stopped to spray, and the cutting assembly 30 is reset, the conveying belt 12 continues to convey intermittently, the cut material is transferred to the inlet 61 of the shaking box 60 through the transfer assembly 13, after the material enters the inside of the shaking box 60 through the inlet 61, the shaking box 60 is started to vibrate to shake off the impurities such as cutting debris, residual spraying liquid drops and the like attached to the surface of the material, the shaken-off impurities are discharged through the bottom discharge port of the shaking box 60, and the purified material is left in the shaking box 60 for subsequent discharge.

[0032] Specifically, the visual, infrared, radar and spectrum sensors are used for quality inspection of the scrap steel raw material, and these instruments are installed at the inlet 61 of the shaking box 60, and when the scrap steel and iron fall, these instruments can be used for quality inspection of the scrap steel and iron. The visual, infrared, radar and spectrum sensors are prior art, which will not be described here.

[0033] Integrating the four core functions of conveying, cutting, spraying and shaking, the device forms a coherent processing flow, reduces manual intervention, improves the degree of automation, reduces labor costs and processing efficiency.

[0034] Specifically, the transfer assembly 13 is a prior art and is not described in detail.

[0035] As an embodiment, according to the description attached Figure 2 It can be seen that the driving assembly 20 comprises a ratchet wheel 21 fixed on a fixed shaft 111 at the end of the rotating roller; a swing rod 22 is arranged on one side of the support plate 10, the upper end of which is hinged to the support plate 10, and the hinge is coaxial with the fixed shaft 111; a pawl 23 is slidably arranged in the guide rail (not marked in the figure) on the swing rod 22 and is located below the ratchet wheel 21, the upper end of the pawl 23 is matched with the ratchet wheel 21; the first connecting rod 24 is hinged at the upper end to the lower end of the pawl 23; the second connecting rod 25 is hinged at the lower end to the lower end of the swing rod 22, and two blocking columns 221 are arranged on the swing rod 22 on both sides of the second connecting rod 25; a rotating wheel 26 is driven to rotate by a first motor 262, and an eccentric fixed column 261 is arranged on the rotating wheel 26; the third connecting rod 27 is connected at the first end to the rotating shaft of the fixed column 261, and the connecting column (not shown in the figure) at the second end is connected to the rotating shaft of the lower end of the first connecting rod 24 and the upper end of the second connecting rod 25, respectively.

[0036] Start the first motor 262 to drive the rotating wheel 26 to rotate at a constant speed. Since the fixed column 261 is eccentrically arranged on the rotating wheel 26, when the rotating wheel 26 rotates, it will drive the third connecting rod 27 to reciprocating swing (one end does circular motion with the fixed column 261, and the other end pulls the connecting column to drive the connecting rod group linkage). When the rotating wheel 26 drives the fixed column 261 to move towards the swing rod 22, the third connecting rod 27 pulls the connecting column, thereby driving the second connecting rod 25 to rotate around the lower end hinge point of the swing rod 22, and pushing the first connecting rod 24 to move upwards. The first connecting rod 24 lifts the pawl 23 upwards, so that it slides upwards in the guide rail of the swing rod 22 and is fully engaged with the ratchet wheel 21. At this time, the second connecting rod 25 gradually approaches the blocking column 221 on one side during the swing process. When the second connecting rod 25 contacts the blocking column 221, the swing rod 22 rotates synchronously around the upper end hinge point under the push of the second connecting rod 25, the swing rod 22 drives the pawl 23 to push the ratchet wheel 21 to rotate, thereby driving the rotating roller (the fixed shaft 111 is fixedly connected with the ratchet wheel 21) to rotate by a certain angle. When the rotating wheel 26 continues to rotate, the fixed column 261 moves away from the swing rod 22, the third connecting rod 27 pulls the connecting column to move reversely, the second connecting rod 25 contacts the blocking column 221 on the other side, and the first connecting rod 24 pulls the pawl 23 downwards, so that it slides downwards in the guide rail and is disengaged from the ratchet wheel 21. At this time, the swing rod 22 is reversely reset under the drive of the third connecting rod 27, but the pawl 23 is disengaged from the ratchet wheel 21 and does not drive the ratchet wheel 21 to reverse, so the rotating roller stops rotating.

[0037] As an example, according to the description attached Figure 2 to the attached drawings Figure 3 It can be seen that the cutting assembly 30 comprises a first support 31 arranged above the conveying belt 12, a cutting plate 32 arranged in the first support 31 on one side of the conveying belt 12, a knife seat 33 arranged on the first support 31 above the cutting plate 32 and driven to rise and fall by a first hydraulic cylinder 34, a cutting knife 331 arranged below the knife seat 33, a pressing plate 35 rotatably arranged in the middle of the support plate 10, a first protrusion 263 arranged on the outer circumferential surface of the rotating wheel 26, the first protrusion 263 being in contact with or separated from the upper surface of the first end of the pressing plate 35, a counterweight 351 fixedly arranged on the lower surface of the second end of the pressing plate 35, a first button 36 fixedly arranged on the support plate 10 above the second end of the pressing plate 35, the second end of the pressing plate 35 pressing or separating from the first button 36, and the first button 36 being electrically connected with the first hydraulic cylinder 34.

[0038] The rotating wheel 26 continuously rotates, the first protrusion 263 presses the first end of the pressing plate 35, the pressing plate 35 rotates around the middle hinge point (the first end sinks, the second end gradually presses the first button 36 upwards), after the first button 36 is triggered, the first hydraulic cylinder 34 sends a start signal to the first hydraulic cylinder 34, the first hydraulic cylinder 34 drives the knife seat 33 to quickly descend, drives the cutting knife 331 to move towards the cutting plate 32, and accurately cuts the material below (the cutting knife 331 and the cutting plate 32 cooperate to complete the cutting action), when the rotating wheel 26 rotates to the first protrusion 263 separates from the first end of the pressing plate 35, the pressing plate 35 reversely rotates and resets under the gravity of the second end counterweight 351, the second end of the pressing plate 35 presses the first button 36 once, and the first hydraulic cylinder 34 will run once.

[0039] The cutting assembly 30 is linked with the pressing plate 35 and the first button 36 through the first protrusion 263 on the rotating wheel 26, realizes the automatic triggering of cutting when the conveying belt 12 is paused, does not need to additionally set an independent control module, simplifies the control logic, and ensures the accurate synchronization of the conveying and cutting actions.
