Description

Technical Field

[0001] This utility model relates to the field of feeder technology, and in particular to a feeder for limestone crushing and feeding. Background Technology

[0002] A feeder is a device used to transport limestone raw materials during limestone crushing. When using a feeder, the limestone raw materials are manually placed on the top of the conveyor belt. The first motor drives the rotating roller to rotate, so that the limestone can be transported to the top of the crusher through the conveyor belt, thus facilitating the crushing of the limestone.

[0003] The inventors discovered in their daily work that the feeder still has at least the following problems: When using the feeder, the limestone raw material is placed manually on the top of the conveyor belt, and the rotating roller is driven by the first motor to rotate. In this way, the limestone can be transported away from the top of the crusher by the conveyor belt, which facilitates the crushing of the limestone. However, in actual use, when the conveyor belt is tilted at a certain angle, the conveyor belt that is manually placed on the conveyor belt may fall off the conveyor belt, and it is necessary to repeatedly place it on the conveyor belt manually, which affects the conveying efficiency to a certain extent. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a limestone crushing and feeding machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feeder for limestone crushing and feeding, comprising a support frame, a first motor fixedly connected to one side of the support frame, a rotating roller fixedly connected to the output end of the first motor, a conveyor belt sleeved on the surface of the rotating roller, a limiting device provided at the top of the support frame, and a lifting device provided at the bottom of the support frame. The limiting device comprises a conical sleeve, the conical sleeve being disposed at the top of the support frame, a rotating rod rotatably inserted into the inner wall of the conical sleeve, a rotating plate fixedly connected to the surface of the rotating rod, and a baffle fixedly connected to the end of the conical sleeve away from the rotating rod.

[0006] The effect achieved by the above components is as follows: when using the limiting device, the conical sleeve is set on the top of the support frame, and the raw material is manually placed inside the conical sleeve. When the raw material moves away from the conveyor belt, the rotating plate is squeezed and rotated on the surface of the rotating rod, so that the rotating plate is blocked by the baffle, thus preventing the raw material from moving away from the surface of the conveyor belt.

[0007] Preferably, a first spring is sleeved on the surface of the rotating rod, one end of the first spring is fixedly connected to one side of the rotating plate, and the end of the first spring near the rotating rod is fixedly connected to one side of the inner wall of the conical sleeve.

[0008] The effect achieved by the above components is that, through the torque force of the first spring, the rotating plate can be returned to its original position without being squeezed.

[0009] Preferably, the top of the support frame is uniformly provided with rectangular grooves, and a first rectangular plate is slidably connected inside the rectangular grooves. The top of the first rectangular plate is fixedly connected to the bottom of the conical sleeve. Limiting plates are fixedly connected to both sides of the conical sleeve. A fixing frame is slidably fitted on the inner wall of the limiting plate. One side of the fixing frame is fixedly connected to one side of the support frame. A groove is provided on one side of the limiting plate.

[0010] The effect achieved by the above components is to slide the first rectangular plate into the inside of the rectangular groove, and then slide the limiting plate into the inside of the fixed frame, so that the conical sleeve can be set on the top of the support frame.

[0011] Preferably, a support plate is fixedly connected to the side of the fixed frame away from the support frame, a first damping rod is fixedly connected to one side of the support plate, a locking strip is fixedly connected to the end of the first damping rod away from the support plate, the locking strip is slidably connected to the inner wall of the groove, a second spring is sleeved on the surface of the first damping rod, one end of the second spring is fixedly connected to one side of the support plate, and the end of the second spring near the first damping rod is fixedly connected to one side of the locking strip.

[0012] The effect achieved by the above components is that the second spring presses the locking strip away from the support plate, causing the locking strip to slide into the inside of the groove, which makes it easier to restrict the limiting plate inside the fixed frame.

[0013] Preferably, the lifting device includes a base plate, a round rod is fixedly connected to one side of the base plate, the round rod is rotatably inserted into the inner wall of the bottom of the support frame, a second motor is fixedly connected to one side of the base plate, and a threaded rod is fixedly connected to the output end of the second motor.

[0014] The effect achieved by the above components is that when the lifting device is used, the round rod can drive the support frame to rotate on the top of the base plate, so that one end of the support frame is raised, and the raw materials can be transported to the high-level processing device.

[0015] Preferably, the support frame has sliding grooves on both sides, and a sliding block is slidably connected to the inner wall of the sliding groove. A second rectangular plate is rotatably inserted into the end of the sliding block away from the sliding groove, and the threaded rod is threaded through and inserted into one side of the second rectangular plate.

[0016] The effect achieved by the above components is as follows: starting the second motor drives the threaded rod to rotate, causing the sliding block to slide on the inner wall of the groove. This can effectively control the rotation of the support frame on one side of the base plate via the round rod.

[0017] Preferably, a connecting cylinder is fixedly connected to one side of the base plate, a sliding rod is slidably connected to the inner wall of the connecting cylinder, the top of the sliding rod is fixedly connected to one side of another second rectangular plate, a connecting ring is fixedly connected to the top of the connecting cylinder, a bolt is threaded through one side of the connecting ring, a circular plate is rotatably sleeved on one end of the bolt, and rubber blocks are uniformly fixedly connected to the end of the circular plate away from the bolt.

[0018] The effect achieved by the above components is as follows: when the support frame rotates, the sliding rod is driven to slide on the inner wall of the connecting cylinder. When the sliding rod slides to the appropriate position, the bolt is manually controlled to rotate, so that the rubber block is squeezed and deformed, thereby effectively restricting the sliding rod inside the connecting cylinder, which can effectively support the support frame.

[0019] Preferably, a second damping rod is fixedly connected to the top of the inner wall of the connecting cylinder, the top of the second damping rod is fixedly connected to the bottom of the sliding rod, a third spring is sleeved on the surface of the second damping rod, the bottom of the third spring is fixedly connected to the bottom of the inner wall of the connecting cylinder, and the end of the third spring near the second damping rod is fixedly connected to the bottom of the sliding rod.

[0020] The effect achieved by the above components is that the sliding rod is pressed away from the inner wall of the connecting cylinder by the second damping rod, which makes it easier to slide the control sliding rod away from the connecting cylinder.

[0021] In this invention, by setting a limiting device, when using the limiting device, the conical sleeve is set on the top of the support frame, and the raw material is manually placed inside the conical sleeve. When the raw material moves away from the conveyor belt, the rotating plate is squeezed and rotates on the surface of the rotating rod, so that the rotating plate is blocked by the baffle, thus preventing the raw material from moving away from the surface of the conveyor belt.

[0027] Example 1, as Figure 1-4 As shown, a limestone crushing and feeding machine has a first motor 2 fixedly connected to one side of a support frame 1. A rotating roller 3 is fixedly connected to the output end of the first motor 2. A conveyor belt 4 is fitted on the surface of the rotating roller 3. A limit device 5 is provided at the top of the support frame 1, and a lifting device 6 is provided at the bottom of the support frame 1. When using the feeder, the limestone raw material is placed manually on the top of the conveyor belt 4. The rotating roller 3 is driven to rotate by the first motor 2. In this way, the limestone can be transported away from the top of the crusher by the conveyor belt 4, which facilitates the crushing of the limestone.

[0028] Reference Figure 2 and Figure 3The limiting device 5 includes a conical sleeve 501, which is disposed on the top of the support frame 1. A rotating rod 502 is rotatably inserted into the inner wall of the conical sleeve 501. A rotating plate 503 is fixedly connected to the surface of the rotating rod 502. A baffle 504 is fixedly connected to the end of the conical sleeve 501 away from the rotating rod 502. When using the limiting device 5, the conical sleeve 501 is disposed on the top of the support frame 1, and the raw material is manually placed inside the conical sleeve 501. When the raw material moves away from the conveyor belt 4, the rotating plate 503 is squeezed and rotated on the surface of the rotating rod 502, causing the rotating plate 503 to be squeezed by the baffle 504. The material is blocked to prevent it from moving away from the surface of the conveyor belt 4. A first spring 505 is fitted on the surface of the rotating rod 502. One end of the first spring 505 is fixedly connected to one side of the rotating plate 503, and the end of the first spring 505 near the rotating rod 502 is fixedly connected to one side of the inner wall of the conical sleeve 501. Through the torque force of the first spring 505, the rotating plate 503 can be returned to its original position without being squeezed. Rectangular grooves 506 are evenly opened on the top of the support frame 1. A first rectangular plate 507 is slidably connected inside the rectangular grooves 506. The top of the first rectangular plate 507 is connected to the bottom of the conical sleeve 501. The tapered sleeve 501 is fixedly connected to both sides of a limiting plate 509. A fixing frame 508 is slidably fitted onto the inner wall of the limiting plate 509. One side of the fixing frame 508 is fixedly connected to one side of the support frame 1. A groove 510 is provided on one side of the limiting plate 509. The first rectangular plate 507 is slid into the rectangular groove 506, and then the limiting plate 509 is slid into the fixing frame 508. This allows the tapered sleeve 501 to be placed on top of the support frame 1. A support plate 511 is fixedly connected to the side of the fixing frame 508 away from the support frame 1. A first damping rod 512 is fixedly connected to one side of the support plate 511. A damping rod 512 is fixedly connected to a locking strip 514 at one end away from the support plate 511. The locking strip 514 is slidably connected to the inner wall of the groove 510. A second spring 513 is sleeved on the surface of the first damping rod 512. One end of the second spring 513 is fixedly connected to one side of the support plate 511, and the end of the second spring 513 near the first damping rod 512 is fixedly connected to one side of the locking strip 514. The locking strip 514 is pressed away from the support plate 511 by the second spring 513, so that the locking strip 514 slides into the inside of the groove 510. This makes it easier to restrict the limiting plate 509 inside the fixed frame 508.

[0029] Reference Figure 4The lifting device 6 includes a base plate 601. A round rod 602 is fixedly connected to one side of the base plate 601. The round rod 602 is rotatably inserted into the inner wall of the bottom of the support frame 1. A second motor 603 is fixedly connected to one side of the base plate 601. A threaded rod 607 is fixedly connected to the output end of the second motor 603. When using the lifting device 6, the round rod 602 can drive the support frame 1 to rotate on the top of the base plate 601, thereby raising one end of the support frame 1 and conveying the raw materials into the high-level processing device. Slide grooves 604 are provided on both sides of the support frame 1, and sliding blocks 605 are slidably connected to the inner wall of the slide grooves 604. A second rectangular plate 606 is rotatably inserted into the end of the sliding block 605 away from the slide groove 604. A threaded rod 607 is threaded through and inserted into one side of the second rectangular plate 606. When the second motor 603 is started, the threaded rod 607 is rotated, causing the sliding block 605 to slide on the inner wall of the slide groove 604. This allows for good control of the support frame 1 rotating on one side of the base plate 601 via the round rod 602. A connecting cylinder 608 is fixedly connected to one side of the base plate 601, and a sliding rod 609 is slidably connected to the inner wall of the connecting cylinder 608. The top of the sliding rod 609 is fixedly connected to one side of the other second rectangular plate 606. Next, a connecting ring 612 is fixedly connected to the top of the connecting cylinder 608. A bolt 613 is threaded through one side of the connecting ring 612. A circular plate 614 is rotatably fitted onto one end of the bolt 613. Rubber blocks 615 are evenly fixedly connected to the end of the circular plate 614 away from the bolt 613. When the support frame 1 rotates, the sliding rod 609 is driven to slide on the inner wall of the connecting cylinder 608. When the sliding rod 609 slides to a suitable position, the bolt 613 is manually rotated, causing the rubber blocks 615 to be squeezed and deformed, thereby effectively confining the sliding rod 609 inside the connecting cylinder 608. This effectively... The support frame 1 supports the top of the inner wall of the connecting cylinder 608, and the top of the second damping rod 610 is fixedly connected to the bottom of the sliding rod 609. A third spring 611 is sleeved on the surface of the second damping rod 610, and the bottom of the third spring 611 is fixedly connected to the bottom of the inner wall of the connecting cylinder 608. The end of the third spring 611 near the second damping rod 610 is fixedly connected to the bottom of the sliding rod 609. The sliding rod 609 is pressed away from the inner wall of the connecting cylinder 608 by the second damping rod 610, which makes it easy to slide the control sliding rod 609 away from the connecting cylinder 608.

[0030] Working principle: When using the feeder, the limestone raw material is manually placed on the top of the conveyor belt 4. The first motor 2 drives the rotating roller 3 to rotate, thus transporting the limestone away from the top of the crusher via the conveyor belt 4, facilitating limestone crushing. When using the limiting device 5, the first rectangular plate 507 slides into the inside of the rectangular groove 506, and the limiting plate 509 slides into the inside of the fixed frame 508. The second spring 513 presses the locking strip 514 away from the support plate 511, causing the locking strip 514 to slide into the inside of the groove 510. This helps to confine the limiting plate 509 inside the fixed frame 508, allowing the conical sleeve 501 to be set on the top of the support frame 1. When the raw material moves away from the conveyor belt 4, the rotating plate 503 is pressed against the surface of the rotating rod 502 and rotates, causing the rotating plate 503 to be blocked by the baffle 504. This prevents the raw material from moving away from the surface of the conveyor belt 4. The torque force of the first spring 505 is used to achieve this. The rotating plate 503 returns to its original position when not being squeezed. When using the lifting device 6, the second motor 603 is started, which drives the threaded rod 607 to rotate, causing the sliding block 605 to slide on the inner wall of the groove 604. This effectively controls the rotation of the support frame 1 on one side of the base plate 601 via the round rod 602, raising one end of the support frame 1. When the support frame 1 rotates, the sliding rod 609 is driven to slide on the inner wall of the connecting cylinder 608. The second damping rod 610 presses the sliding rod 609 away from the inner wall of the connecting cylinder 608, making it easier to control the sliding rod 609 to slide away from the connecting cylinder 608. When the sliding rod 609 slides to the appropriate position, the manual control bolt 613 is rotated, causing the rubber block 615 to be squeezed and deformed, thus effectively confining the sliding rod 609 inside the connecting cylinder 608. This effectively supports the support frame 1, allowing the raw materials to be transported to the high-level processing device.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
