Abstract
Description
Technical Field
[0001] This utility model belongs to the field of quartz sand production technology, specifically a crocodile crushing device for quartz sand production. Background Technology
[0002] Quartz sand production uses natural quartz as raw material. Through core processes such as crushing, screening, sand making, and purification, it ultimately produces quartz sand with uniform particle size and meeting purity standards. It is widely used in glass manufacturing, photovoltaic silicon wafers, building materials, and other fields. Among these processes, the crushing stage requires crushing large pieces of quartz (with diameters reaching tens of centimeters) to a particle size suitable for subsequent processing (usually 5-20mm). Jaw crushers, due to their stable structure and high compressive strength, have become the core equipment in the crushing stage of quartz sand production. They crush materials through the periodic squeezing and shearing action of movable jaw plates and fixed jaw plates, efficiently completing coarse or medium crushing operations for quartz.
[0003] The existing jaw crusher for quartz sand production still has the following shortcomings: When using the existing jaw crusher for quartz sand production, quartz stones of various sizes are usually directly added to the crushing chamber, which may cause large pieces of quartz stones to get stuck in the crushing chamber, causing "lockdown" and forcing the production line to stop for cleaning, which seriously affects production efficiency. At the same time, large pieces of quartz stones will aggravate the local impact and wear of the moving jaw plate and the fixed jaw plate, shortening their service life. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a crocodile crushing device for quartz sand production, which solves the problems existing in the crocodile crushing devices for quartz sand production.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a jaw crusher for quartz sand production, comprising a crusher body, a guide hopper at the top of the crusher body, two pairs of connecting columns fixedly connected to the bottom of the guide hopper, each connecting column being fixedly connected to the crusher body at its bottom, two pairs of support rods fixedly connected to the top of the guide hopper, a guide rod fixedly connected between each pair of support rods, a slider slidably connected to the guide rod, a barrier fixedly connected between a pair of sliders, a screen frame at the bottom of the barrier, a discharge grid plate at the bottom of the screen frame, a pair of first connecting blocks fixedly connected to one side of the barrier, a transmission rod fixedly connected between the pair of first connecting blocks, a pair of second connecting blocks rotatably connected to the transmission rod, one side of each pair of second connecting blocks being fixedly connected to the screen frame, adjusting components on both sides of the barrier, a base fixedly connected to one side of the guide hopper, and a driving component on the top of the base.
[0006] As a further embodiment of this utility model: the adjustment component includes a first connecting shaft, which is fixedly connected to the corresponding side of the enclosure. A rotating seat is rotatably connected to the first connecting shaft. A hydraulic cylinder is fixedly connected to the bottom of the rotating seat. A spherical bearing is fixedly connected to the output end of the hydraulic cylinder. A second connecting shaft is rotatably connected to the spherical bearing. One end of the second connecting shaft is fixedly connected to the screen frame.
[0007] As a further embodiment of this utility model: the drive assembly includes a mounting plate, which is fixedly connected to the top of the base. A servo motor is fixedly connected to one side of the mounting plate. The output end of the servo motor passes through the mounting plate and is rotatably connected to it. A rotating rod is coaxially fixedly connected to the output end of the servo motor. A connecting pin is fixedly connected to one side of the rotating rod. A connecting rod is rotatably connected to the connecting pin. One end of the connecting rod is rotatably connected to the transmission rod.
[0008] As a further embodiment of this utility model: a diagonal brace is fixedly connected to one side of the support rod, and one end of the diagonal brace is fixedly connected to the guide hopper.
[0009] As a further embodiment of this utility model, a baffle is fixedly connected to the bottom of the enclosure.
[0010] As a further embodiment of this utility model, a guide plate is fixedly connected to one side of the screen frame.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model includes a guide hopper, support rods, guide rods, sliders, a baffle, a screen frame, a discharge grid plate, a first connecting block, a transmission rod, a second connecting block, an adjustment component, and a drive component. Initially, the screen frame and the baffle are parallel. The drive component drives the baffle to move via the transmission rod and the first connecting block. The baffle reciprocates along the guide rod between a pair of support rods via the slider. The screen frame moves with the baffle, and the quartz falls onto the discharge grid plate inside the screen frame for screening. Quartz of suitable particle size falls into the crushing chamber of the crusher body through the guide hopper, avoiding "stalling" and shutdown caused by large pieces of quartz stuck in the chamber. At the same time, it avoids the rigid impact and excessive wear of large pieces of quartz on the moving jaw plate and the fixed jaw plate, reducing the replacement frequency of vulnerable parts such as jaw plates. A small amount of large pieces of quartz remain on the discharge grid plate. The adjustment component can drive the screen frame to rotate and tilt at a certain angle around the transmission rod via the second connecting block, which facilitates the quick discharge of the stuck large pieces of quartz.

Specifically, initially, the screen frame 8 and the enclosure 7 are kept parallel. The drive component drives the enclosure 7 to move through the transmission rod 11 and the first connecting block 10. The enclosure 7 moves back and forth along the guide rod 5 between a pair of support rods 4 via the slider 6. The screen frame 8 moves together with the enclosure 7. Quartz stones fall onto the discharge grid plate 9 inside the screen frame 8 for screening. Quartz stones of suitable size fall into the crushing chamber of the crusher body 1 through the guide hopper 2, avoiding "stalling" and shutdown caused by large pieces of quartz stones stuck in the chamber. At the same time, it avoids the rigid impact and excessive wear of large pieces of quartz stones on the movable jaw plate and fixed jaw plate, reducing the replacement frequency of vulnerable parts such as jaw plates. A small number of large pieces of quartz stones remain on the discharge grid plate 9. The adjustment component can drive the screen frame 8 to rotate and tilt at a certain angle around the transmission rod 11 via the second connecting block 12, which facilitates the quick discharge of the stuck large pieces of quartz stones. The adjustment assembly includes a first connecting shaft 14, which is fixedly connected to the corresponding side of the enclosure 7.
