When useless glass smashes to be useless glass particle through smashing the roller, useless glass particle drops to conveyer belt 21 from the discharge gate 13 that smashes storehouse 11 on, and then collects useless glass particle.
Specifically, referring to fig. 1 and 2, the discharge side of the conveyor belt 21 is provided with a collection box 3 for collecting the waste glass particles, and the top of the collection box 3 is open. The open end of the collection box 3 is rotatably provided with a scraper 4 for collecting waste glass particles adhering to the surface of the conveyor belt 21 on the side close to the crushing bin 11. The scraper 4 includes a guide plate 41 and a scraper 42 for scraping off waste glass particles adhering to the surface of the conveyor belt 21. The guide plate 41 includes a connection portion 411 and an inclined portion 412, and one side of the connection portion 411 is fixedly connected to the wiper blade 42, and the other side of the connection portion 411 is fixedly connected to the inclined portion 412. When the inclined portion 412 rotates, the inclined portion 412 drives the connecting portion 411 to rotate, the connecting portion 411 drives the scraper 42 to rotate, when the scraper 42 abuts against the surface of the conveyor belt 21, the scraper 42 scrapes off the waste glass particles attached to the surface of the conveyor belt 21 onto the connecting portion 411, then the waste glass particles slide from the connecting portion 411 to the inclined portion 412, and finally the waste glass particles are collected in the collection box 3 from the inclined portion 412.
Specifically, referring to fig. 1 and 2, a driving mechanism for driving the scraper 4 to rotate is arranged at one side of the open end of the collecting box 3 close to the crushing bin 11, and the driving mechanism comprises a rotating shaft 5 which is horizontally arranged and a locking component. One side that the open end of collecting box 3 is close to crushing storehouse 11 is fixed to be provided with two fixed ears 6, and two fixed ears 6 enclose and close the rotation space that forms rotation axis 5, and the one end of rotation axis 5 runs through the lateral wall of scraper blade 4 and welds with scraper blade 4 lateral wall for when rotation axis 5 rotated, scraper blade 4 rotated along with rotation axis 5 is synchronous. The other end of the rotating shaft 5 is a free end, and the free end of the rotating shaft 5 passes through one of the fixing lugs 6 and is rotatably connected with the fixing lug 6. The free end of rotation axis 5 is fixed with the pivoted piece that rotates of drive rotation axis 5, rotates the piece and is hand wheel 7, and hand wheel 7 is vertical setting, and hand wheel 7 and the coaxial fixed connection of free end of rotation axis 5. When the staff rotates the hand wheel 7, the hand wheel 7 drives the rotation shaft 5 to rotate, the rotation shaft 5 drives the scraping plate 4 to rotate, and then the scraping plate 42 abuts against the surface of the conveyor belt 21.
Specifically, referring to fig. 1 and 2, the locking assembly includes a ratchet 81 and a pawl 82, and the ratchet 81 is fixedly sleeved on one end of the rotating shaft 5 close to the hand wheel 7. One side of the collecting box 3 facing the crushing bin 11 is fixedly provided with a horizontally arranged supporting rod 8, a pawl 82 is correspondingly and rotatably arranged on the supporting rod 8, and the pawl 82 is meshed with the ratchet 81. When the worker rotates the hand wheel 7 forward, the hand wheel 7 drives the rotating shaft 5 to rotate forward, and the rotating shaft 5 drives the scraping plate 4 to swing along the direction close to the conveyor belt 21 until the scraping plate 42 abuts against the surface of the conveyor belt 21. Due to the unidirectional nature of the ratchet 81 and pawl 82 interaction, the operator releases the hand wheel 7 and under the weight of the squeegee 4, the pawl 82 engages the ratchet 81, at which time the squeegee 4 is fixed in the current position.
It is worth to be noted that, referring to fig. 2, the two limit blocks 9 are fixedly sleeved on the support rod 8, and the two limit blocks 9 are respectively fixedly sleeved on the left side and the right side of the pawl 82, which is beneficial to improving the stability of the rotation of the pawl 82.
The utility model provides a waste glass retrieves and uses reducing mechanism's theory of operation:
when the glass attached to the conveyor belt 21 needs to be cleaned, a worker firstly holds the hand wheel 7 and rotates the hand wheel 7 forwards. The hand wheel 7 drives the rotating shaft 5 to rotate positively, the rotating shaft 5 drives the scraper 4 to swing in the direction close to the conveyor belt 21, the ratchet 81 drives the pawl 82 to rotate on the bearing rod 8, when the scraper 4 drives the scraper 42 to rotate until the scraper 42 abuts against the lower surface of the conveyor belt 21, a worker loosens the hand wheel 7, due to the fact that the ratchet 81 and the pawl 82 have one-way property, under the action of gravity of the scraper 4, the pawl 82 is meshed with the ratchet 81, the scraper 4 is fixed at the current position, and the scraper 42 scrapes waste glass particles attached to the surface of the conveyor belt 21 onto the guide plate 41 and finally slides into the collection box 3.
It should be noted that when the conveyor belt needs to be repaired, the worker first disengages the pawl 82 from the ratchet 81, and the inclined portion 412 of the scraper 4 is supported on the support rod 8 by gravity, and the scraper 42 is disengaged from the surface of the conveyor belt 21.
As described above, the contact of the blade 42 against the surface of the conveyor belt 21 facilitates collection of the waste glass particles adhering to the conveyor belt 21.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
