The rotating rod guides the material placed on the feed roller into the crushing chamber for crushing;

[0025] S5. When the gear ring needs to be replaced, the gear ring is pushed to separate into the upper gear ring and the lower gear ring. As the upper gear ring and the lower gear ring move on the guide rail surface, the pins and slots no longer restrict the positions of the upper gear ring and the lower gear ring. The upper gear ring and the lower gear ring can be removed from the rotating rod, and the new upper gear ring and the lower gear ring can be reinstalled by reversing the operation.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The set closed door, motor bin and motor effectively avoid the problem of slow manual loading. The workers need to carry the materials to the feeding port on the top of the equipment to feed the materials. It is difficult to work effectively when crushing materials longer than the height of the equipment, and it consumes a lot of physical energy for the workers. After the closed door is opened by the rotating mechanism and removed from the inside of the chamber entrance, the motor inside the motor bin can be started, so that the motor drives the transmission belt to rotate through the transmission wheel, and the transmission belt drives the rotating rod to rotate. The rotating rod drives other rotating rods to rotate together through the transmission mechanisms on both sides.

[0028] 2. Through the provided adjusting slots, sliders and connecting shafts, the staff can pull the handle to open the closed door, so that the handle drives the rotating disk to move by rotating the crank, and the rotating disk drives the limit disk to move under the guidance of the limit rail.

[0041] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific examples, but the following examples are only preferred embodiments of the present invention, not all. Based on the examples in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention. The experimental methods in the following examples, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following examples, unless otherwise specified, can be obtained from commercial channels.

[0042] Example:

[0043] like Figure 1 - Figure 11 As shown, this embodiment proposes a crusher with a fast feeding mechanism, comprising a crusher body 1, a crushing chamber 2 and a chamber entrance 3. The crushing chamber 2 is provided on the crusher body 1, and the chamber entrance 3 is opened at the front end of the crushing chamber 2. The surface of the chamber entrance 3 is covered with a closed door 41, and the closed door 41 is provided with a feeding mechanism. After the closed door 41 is opened, the material enters the crushing chamber 2 through the feeding mechanism.

[0044] The closed door 41 is fixedly mounted with a rotating mechanism on both sides of the outer wall, and the rotating mechanism is connected to the front end surface of the outer wall of the crushing chamber 2. The closed door 41 is opened by the rotating mechanism and removed from the inside of the chamber entrance 3;

[0045] The feeding mechanism includes a motor compartment 42 provided inside a closed door 41, a motor 43 is fixedly mounted on the middle of the inner wall of the motor compartment 42, and a transmission wheel 44 is fixedly mounted on the output end of the motor 43;

[0046] A plurality of groups of rotatable rotating rods 46 are equidistantly arranged on both sides of the inner wall of the closed door 41 through bearings, and each group of rotating rods 46 is connected by a transmission mechanism. A transmission belt 45 is sleeved on the middle part of the rotating rod 46 closest to the motor 43, and the other end of the transmission belt 45 is sleeved on the surface of the transmission wheel 44. The motor 43 drives the transmission belt 45 through the transmission wheel 44 to pull the rotating rods 46 to rotate. The surface of each rotating rod 46 is sleeved with a feed roller 47;

[0047] When loading is required, the closed door 41 is opened by the rotating mechanism and removed from the chamber entrance 3, the closed door 41 is adjusted to a state where it is level with the ground, and then the motor 43 inside the motor compartment 42 is started, so that the motor 43 drives the transmission belt 45 to rotate through the transmission wheel 44, and the transmission belt 45 drives the rotating rod 46 to rotate, so that the rotating rod 46 drives other rotating rods 46 to rotate together through the transmission mechanisms on both sides, and the material to be crushed is placed on the surface of the feeding roller 47, and the rotating rod 46 introduces the material placed on the feeding roller 47 into the crushing chamber 2 by rotation. After the material is introduced, the closed door 41 is closed again to carry out crushing, which improves the convenience of the device when in use.

[0048] The transmission mechanism includes gear rings 48 mounted on both ends of the rotating rods 46. Each set of gear rings 48 on the same side is mounted with an internal gear belt 49. When the rotating rod 46 closest to the motor 43 drives the gear ring 48 to rotate, the internal gear belt 49 and other gear rings 48 can drive the other rotating rods 46 to rotate synchronously.

[0049] When the motor 43 is started, it can drive the transmission belt 45 to rotate through the transmission wheel 44, and the transmission belt 45 drives the rotating rod 46 to rotate, so that the rotating rod 46 drives the internal gear belt 49 to rotate through the gear rings 48 on both sides. The internal gear belt 49 can drive other rotating rods 46 to rotate together through other gear rings 48. The rotating rod 46 rotates to guide the material placed on the feed roller 47 into the crushing chamber 2 for crushing.

[0050] In order to allow for quick replacement of worn toothed rings 48 and inner gear belts 49 without removing the rotating rod 46, the toothed rings 48 can be separated from the middle into an upper toothed ring 51 and a lower toothed ring 52. A guide rail 53 is integrally formed on the outer wall of the rotating rod 46, and a groove 54 is formed on the inner surface of each of the upper and lower toothed rings 51, 52 to engage with the guide rail 53.

[0051] The guide rail 53 has a spring slot 55 formed inside, and latches 56 are provided at both ends of the spring slot 55. A first spring 57 is provided between the two sets of latches 56.

[0052] Slots 58 are formed on both sides of the inner wall of the slot 54, and the first springs 57 can be inserted into the slots 58. The outer ends of the latches 56 are each configured as arc-shaped, and the slots 58 are each configured as arc-shaped grooves that cooperate with the latches 56. Through this design, when the outer ends of the latches 56 are subjected to an external force with a specific arc angle, the latches 56 can be displaced and moved out of the slots 58, thereby achieving the purpose of removing the restriction of the latches 56 and the slots 58 on the position of the slot 54.

[0053] When the gear ring 48 needs to be replaced, the gear ring 48 is pushed to separate it into an upper gear ring 51 and a lower gear ring 52. As the upper gear ring 51 and the lower gear ring 52 move on the surface of the guide rail 53, the upper gear ring 51 and the lower gear ring 52 respectively drive the slot 58 to move through the card slot 54 and squeeze the latch 56. The latch 56 moves toward the inside of the spring slot 55 due to the squeezing of the slot 58 and squeezes the first spring 57. The latch 56 can be moved out from the inside of the slot 58. The latch 56 no longer cooperates with the slot 58 to limit the position of the upper gear ring 51 and the lower gear ring 52. The upper gear ring 51 and the lower gear ring 52 can be moved under the guidance of the guide rail 53 and removed from the rotating rod 46. The reverse operation can be performed to reinstall the new upper gear ring 51 and the lower gear ring 52.

[0054] The rotating mechanism includes an adjusting groove 61 provided on the outer wall of the crushing chamber 2 on both sides of the chamber inlet 3, and a groove is provided on the inner surface of the adjusting groove 61, in which a slider 62 is embedded, and the slider 62 can move and rotate in the groove. The inner surface of the slider 62 is connected to a connecting shaft 63, and two sets of connecting shafts 63 are respectively provided on the outer wall of the closed door 41. The position and rotation angle of the slider 62 are adjusted and fixed by a limit device.

[0055] When the closed door 41 needs to be opened, the closed door 41 needs to first drive the slider 62 to translate under the guidance of the adjustment groove 61 through the connecting shaft 63. After the closed door 41 moves out from the inside of the chamber entrance 3, the closed door 41 is rotated so that the closed door 41 drives the adjustment groove 61 to rotate and open under the restriction of the slider 62 through the connecting shaft 63. The closed door 41 stops rotating after it rotates to be level with the ground. The closed door 41 can carry the material to be crushed and wait for loading.

[0056] The limiting device includes an adjusting hole 71 on the outer surface of the adjusting slot 61, and the adjusting hole 71 is formed on the upper and lower sides; two sets of limiting rails 74 are integrally formed on the outer wall of the adjusting slot 61 on both sides;

[0057] The outer surface of the slider 62 is connected to a rotating disk 72, and the rotating disk 72 passes through the middle of the adjustment hole 71. The outer surface of the rotating disk 72 is sleeved with a limit disk 73, and the outer wall surface of the limit disk 73 is provided with two groups of through holes that engage with the limit rails 74.

[0058] A rotating crank 75 is fixedly mounted on the middle portion of the outer surface of the rotating disk 72, and a bolt groove 91 is formed on the outer wall surface of the rotating crank 75. A handle 76 is provided on the outer surface of the bolt groove 91, and a bolt 92 is connected to the inner end of the handle 76. A semicircular guide groove 94 is formed on the outer wall surface of the limiting disk 73, and the inner end of the bolt groove 91 is movably embedded in the guide groove 94. A threaded groove 95 is formed inside the guide groove 94, and the threaded groove 95 can be meshed with the bolt 92.

[0059] When the closed door 41 needs to be opened, the handle 76 is pulled, and the handle 76 pulls the slider 62 to move the connecting shaft 63 under the restriction of the adjustment groove 61, and the connecting shafts 63 on both sides drive the closed door 41 to move out from the inside of the chamber entrance 3;

[0060] Then, the handle 76 is rotated so that the handle 76 drives the bolt 92 to rotate within the limit of the bolt groove 91. The bolt 92 is rotated out of the threaded groove 95, so that the rotating disk 72 can rotate within the limiting disk 73. The handle 76 then drives the rotating disk 72 to rotate, so that the rotating disk 72 drives the connecting shaft 63 to rotate through the slider 62. The connecting shafts 63 on both sides drive the closed door 41 to rotate to a horizontal state. The bolt groove 91 and the guide groove 94 cooperate to limit the rotation angle of the rotating disk 72, thereby preventing the closed door 41 from rotating too much and tilting.

[0061] After the closed door 41 is rotated, the handle 76 is rotated again to drive the bolt 92 to be inserted into the thread groove 95 on the other side of the guide groove 94. The position of the rotating disk 72 is re-fixed, and the closed door 41 is adjusted and fixed.

[0062] In order to enable the rotating disk 72 to rotate inside the limiting disk 73, an annular limiting ring 81 is integrally formed on the inner wall surface of the limiting disk 73, and an annular limiting groove 82 is opened on the outer wall surface of the rotating disk 72. The limiting grooves 82 are all meshed with the limiting ring 81. A number of groups of rolling balls 83 are equidistantly embedded around the two side surfaces of the outer wall of the limiting ring 81, and the balls 83 are all in contact with the inner walls of the limiting grooves 82. Through this design, the rotating disk 72 can drive the limiting groove 82 to rotate under the restriction of the limiting ring 81, and drive the balls 83 to roll during the rotation process, thereby achieving the purpose of improving the stability and smoothness of the rotating disk 72 when rotating inside the limiting disk 73.

[0063] In order to enable the bolt 92 to automatically retract into the bolt groove 91 after being rotated out of the thread groove 95, a second spring 93 is wound around the surface of the bolt 92, one end of the second spring 93 is connected to the inner wall surface of the bolt groove 91, and the other end is attached to the outer wall surface of the bolt 92. Through this design, after the bolt 92 is rotated out of the thread groove 95, since the bolt 92 no longer applies pressure to the second spring 93, the second spring 93 can push the bolt 92 to return to its original position through the reaction force generated by elastic deformation recovery, and the bolt 92 can be retracted into the bolt groove 91, avoiding interference when the bolt groove 91 rotates inside the guide groove 94, and since the second spring 93 is not connected to the outer wall of the bolt 92, it will not affect the normal rotation of the bolt 92.

[0064] The specific steps for using a crusher with a quick loading mechanism are as follows:

[0065] S1. Pull the handle 76, so that the handle 76 drives the rotating disk 72 to move by rotating the crank 75, so that the rotating disk 72 drives the limiting disk 73 to move under the guidance of the limiting rail 74. At the same time, the rotating disk 72 drives the slider 62 to move inside the adjusting slot 61 under the guidance of the adjusting hole 71. The slider 62 drives the closing door 41 to move out of the chamber entrance 3 through the connecting shaft 63, and the closing door 41 is ready to rotate;

[0066] S2. Rotate the handle 76 so that the handle 76 drives the bolt 92 out of the thread groove 95. The restriction of the thread groove 95 and the bolt 92 on the rotating disk 72 is released. At the same time, the bolt 92 is pushed back into the bolt groove 91 by the elastic deformation recovery of the second spring 93.

[0067] S3. Rotate the handle 76 so that the handle 76 drives the bolt slot 91 to rotate within the limit of the guide slot 94 by rotating the crank 75. Rotate the crank 75 to rotate the rotating disk 72 so that the rotating disk 72 can drive the slider 62 to rotate within the adjustment slot 61 within the limit of the limit slot 82 and the limit ring 81. The slider 62 drives the closed door 41 to rotate and open through the connecting shaft 63. After the closed door 41 is opened, the handle 76 is rotated again to rotate the bolt 92 into another threaded slot 95. The threaded slot 95 cooperates with the bolt 92 to re-limit the position of the rotating disk 72. The closed door 41 cannot drive the slider 62 to continue to rotate within the adjustment slot 61.

[0068] S4. Start the motor 43, so that the motor 43 drives the transmission belt 45 to rotate through the transmission wheel 44, and the transmission belt 45 drives the rotating rod 46 to rotate, so that the rotating rod 46 drives the internal gear belt 49 to rotate through the gear rings 48 on both sides. The internal gear belt 49 can drive other rotating rods 46 to rotate together through other gear rings 48. The rotating rods 46 rotate to guide the material placed on the feed roller 47 into the crushing chamber 2 for crushing;

[0069] S5. When the gear ring 48 needs to be replaced, the gear ring 48 is pushed to separate it into the upper gear ring 51 and the lower gear ring 52. As the upper gear ring 51 and the lower gear ring 52 move on the surface of the guide rail 53, the pin 56 and the slot 58 no longer restrict the position of the upper gear ring 51 and the lower gear ring 52. The upper gear ring 51 and the lower gear ring 52 can be removed from the rotating rod 46. The reverse operation can be performed to reinstall the new upper gear ring 51 and the lower gear ring 52.
