[0075] The above technical solution is explained as follows: when the collection frame 30 is fully retracted onto the first support seat 301, the first motor 205 drives the sprocket 201 to rotate, and the sprocket 201 drives the chain 202 to transmit, so that the first support seat 301 drives the collection frame 30 to approach the top of the first side plate 20. The second motor 401 drives the steel ball screw 402 to work, and the ball nut 404 drives the first side plate 20 and the collecting frame 30 to move upward. At the same time, the first laser ranging sensor 4012 detects the distance between the ball nut 404 and the top of the stand 40, so that the rising distance of the collecting frame 30 can also be determined. After rising to a suitable distance, the hydraulic cylinder 304 is started to push the collecting frame 30 to slide toward the feeding direction of the outer shell 60 again, and the card slot 306 will also be connected to the push rod 108, so that the push rod 108 pulls the pull rope 407, and the pull rope 407 drives the winding disk 406 to rotate, and the winding disk 406 drives the articulated frame and the stand 40 to rotate outward, so that the collecting frame 30 is in a tilted state, so that all the ore on the collecting frame 30 falls into the outer shell 60 for re-crushing, refer to the attached Fig.16 The status shown in .

[0076] In order for those skilled in the art to fully understand the technical solution, the method of using this embodiment is as follows:

[0077] The pulley 6014 is connected to an external driving device, such as a driving motor, a diesel engine, etc., through the transmission of a belt. The pulley 6014 drives the rotating rod 6013 to rotate. The rotating rod 6013 drives the rotating sleeve 609 to rotate through the cooperation of the bevel gear 6015 and the bevel gear 6015. The rotating sleeve 609 drives the eccentric shaft 608 to rotate. The eccentric shaft 608 drives the moving cone liner 606 to rotate under the fixed cone liner 604. The ore is then transported into the housing 60 and enters between the fixed cone liner 604 and the moving cone liner 606 for crushing. The crushed ore falls.

[0078] The crushed ore falls into the screening box 50, and is screened out through the gaps between the partition bars 501 and collected;

[0079] The situation for the screening box 50 is as follows:

[0080] 1. When iron protection is required, the cylinder 602 needs to be started to drive the fixed cone liner 604 to move upward, so that there is a large gap between it and the fixed cone liner 604, so that the iron blocks and a large amount of uncrushed ore fall into the screening box 50, and then the iron blocks are taken out;

[0081] Second, if a large amount of incompletely crushed ore is collected in the screening box 50, it will accumulate in the screening box 50;

[0082] The above two situations will cause the weight of the screening box 50 to increase, thereby causing the screening box 50 to move downward. At this time, the second laser distance sensor 504 is used to detect the distance, and the detected distance is the distance between the second side plate 503 and the fixed plate 103. If the distance reaches the limit, which is the distance after the first electromagnet 104 contacts the fixed plate 103, the control module energizes the first electromagnet 104 to absorb and fix the fixed plate 103, thereby fixing the position of the screening box 50.

[0083] Subsequently, the hydraulic cylinder 304 is started to push the collecting frame 30 forward until one end of the collecting frame 30 contacts the synchronous plate 5019. After the synchronous plate 5019 is contacted by the collecting frame 30, it slides backward until the engaging protrusion 5018 is disengaged from the positioning groove 5022, so that the ore in the screening box 50 presses the screening plate 502 to rotate downward, and the bottom center of the screening box 50 is opened, and the ore falls into the collecting frame 30. After it falls completely, there is no ore on the screening plate 502, so that under the torsion of the torsion spring 5011, the rotating shaft 5010 drives the rotating arm 5026 to rotate upward and reset, so that the screening plate 502 is blocked at the bottom of the screening box 50 again.

[0084] Next, the hydraulic cylinder 304 is controlled to drive the collecting frame 30 to retract, and the collecting frame 30 no longer conflicts with the synchronous plate 5019. Under the elastic force of the third spring 5016, the limit plate 5017 drives the clamping protrusion 5018 to clamp in the positioning groove 5022 again, and the first electromagnet 104 is powered off, and no longer adsorbed with the second side plate 503. Then, the elastic force of the second spring 507 is used to push the screening box 50 to move upward and reset.

[0085] When the collecting frame 30 is completely retracted onto the first support seat 301, the first motor 205 is started to drive the sprocket 201 to rotate, and the sprocket 201 drives the chain 202 to transmit, so that the first support seat 301 drives the collecting frame 30 to approach the top of the first side plate 20;

[0086] Next, the second motor 401 is started to drive the steel ball screw 402 to work, and the steel ball screw 402 drives the ball nut 404 to work, and the ball nut 404 drives the first side plate 20 and the collection frame 30 to move upward. At the same time, the first laser ranging sensor 4012 detects the distance between the ball nut 404 and the top of the stand 40, so as to determine the rising distance of the collection frame 30. After it rises to a suitable distance;

[0087] The hydraulic cylinder 304 is started to push the collecting frame 30 to slide in the feeding direction of the shell 60 again, and the card slot 306 is also connected to the push rod 108, so that the push rod 108 pulls the pull rope 407, and the pull rope 407 drives the winding disk 406 to rotate, and the winding disk 406 drives the articulated frame and the stand 40 to rotate outward, so that the collecting frame 30 is in a tilted state, so that all the ore on the collecting frame 30 falls into the shell 60 for re-crushing, refer to the attached Fig.16 As shown in the figure, due to the arrangement of the pull rope 407 and the push rod 108, even if the stand 40 and the collection frame 30 are in a tilted state, it will not affect the pulling of the pull rope 407.

[0088] Embodiment 2

[0089] This embodiment is different from the first embodiment in that, in this embodiment, a second electromagnet 5020 is fixedly connected to the outside of the synchronization plate 5019, a mounting plate 5023 is fixedly connected to the outside of the fixed block 5012, a third laser ranging sensor 5024 is fixedly connected to the mounting plate 5023, a measuring plate 2025 is fixedly connected to the outside of the rotating arm 5026, and the third laser ranging sensor 5024 is electrically coupled to the control module.

[0090] The technical solution of this embodiment is explained as follows:

[0091] In the initial state, the third laser distance sensor 5024 detects the distance A between the mounting plate 5023 and the measuring plate 2025. When the collecting frame 30 contacts the synchronous plate 5019, the second electromagnet 5020 is energized and adsorbed to the collecting frame 30. As the collecting frame 30 pushes, the synchronous plate 5019 is pushed to move. When the screening plate 502 rotates downward, the rotating arm 5026 drives the measuring plate 2025 to move upward, thereby escaping from the measurement of the third laser distance sensor 5024. At this time, the third laser distance sensor 5024 measures The distance is greater than A, and when the ore falls into the collecting frame 30, there is no ore on the screening plate 502, so that under the torque of the torsion spring 5011, the rotating shaft 5010 drives the rotating arm 5026 to rotate upward and reset, so that the screening plate 502 is blocked at the bottom of the screening box 50 again. At this time, the third laser ranging sensor 5024 detects the distance A between the mounting plate 5023 and the measuring plate 2025 again, and the control module cuts off the power to the second electromagnet 5020, so that it is no longer adsorbed with the collecting frame 30, and controls the hydraulic cylinder 304 to retract the collecting frame 30.
