Description

Technical Field

[0001] The utility model relates to the technical field of limestone, in particular to a limestone abrasive device with an anti-blocking function. Background Technique

[0002] In the limestone processing industry, the abrasive device is an indispensable and important piece of equipment, which is used to grind the original limestone blocks into powders or fine grains that meet certain particle size requirements for subsequent processes. However, some significant problems have emerged in the long-term use of traditional limestone abrasive devices, especially the blockage phenomenon that is prone to occur at the discharge hole position.

[0003] Specifically, when the limestone blocks are ground into powders in the abrasive device, these powders often stick together due to electrostatic action, humidity changes or frictional force between particles, forming larger particle clusters. When these particle clusters pass through the discharge hole, they are easily stuck in the hole due to their excessive size, causing blockage.

[0004] The blockage problem not only affects the normal operation of the abrasive device, but also brings many inconveniences to the subsequent production process. Blockage will cause the working efficiency of the abrasive device to be greatly reduced, because the operator needs to frequently stop the machine to take out the grinding head and then clean the blockage, which not only consumes a lot of time, but also increases the equipment maintenance cost. Content of the Utility Model

[0005] The purpose of the utility model is to provide a limestone abrasive device with an anti-blocking function, which solves the problems that the blockage problem in the prior art not only affects the normal operation of the abrasive device, but also brings many inconveniences to the subsequent production process.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A limestone abrasive device with an anti-blocking function includes an abrasive cylinder, a collection box and a top cover;

[0008] A discharge hole is opened at the center of the bottom of the abrasive cylinder, and an arc-shaped groove connected to the discharge hole and shaped like a semicircle is opened at the bottom of the inner cavity of the abrasive cylinder. The top edge of the collection box is detachably connected to the bottom of the abrasive cylinder;

[0009] The top cover is connected to the top of the abrasive cylinder. A handle is arranged on the top of the top cover. A round rod with one end passing through the top cover through a sliding sleeve is connected to the center of the bottom of the handle. The bottom end of the round rod is connected to a grinding head through a driving component. The size of the grinding head is adapted to the size of the arc-shaped groove, and a plugging rod adapted to the discharge hole is fixedly connected to the center of the bottom of the grinding head. The edge of the driving component is connected to the bottom of the inner cavity of the abrasive cylinder through a plurality of elastic guiding components.

[0010] Preferably, the length of the plugging rod is greater than the height of the grinding head, and an anti-slip pad is connected to the outer ring of the grip.

[0011] Preferably, a connecting edge ring fixedly connected to the top edge of the collection box and bolted to the bottom of the collection box is provided.

[0012] Preferably, the driving assembly includes a top plate connected to the bottom end of the round rod and a mounting plate arranged at the bottom of the top plate. The top plate is connected to the mounting plate through a plurality of fixing rods. A driving motor is mounted on the top of the mounting plate, and the output shaft of the driving motor passes through the mounting plate through a bushing and is connected to the top of the grinding head.

[0013] Preferably, a plurality of side rods are connected to the outer ring of the mounting plate. A sliding hole is provided on one side of the top of each side rod, and a guide rod connected to the bottom of the inner cavity of the abrasive cylinder is slidably connected inside the sliding hole. The bottom of each side rod is elastically connected to the bottom of the inner cavity of the abrasive cylinder through an elastic member.

[0014] Preferably, the elastic member is a compression spring. One end of the compression spring is elastically connected to the bottom of the side rod, and the other end is elastically connected to the bottom of the inner cavity of the abrasive cylinder.

[0015] The utility model at least has the following beneficial effects:

[0016] Through the settings of the grinding head, the discharge hole and the plugging rod, it is convenient to realize that by opening the top cover and driving the round rod and the grinding head to rise by grasping the grip, a certain distance can be formed between the grinding head and the arc-shaped groove, which is convenient to put the limestone raw material into the inside of the arc-shaped groove. At this time, the plugging rod is still inside the discharge hole, and the limestone is inside the arc-shaped groove but will not fall into the collection box through the discharge hole. Then, the driving assembly drives the grinding head to rotate, and then the elastic guiding assembly drives the grinding head to move up and down inside the arc-shaped groove, so as to fully grind the limestone raw material. After grinding, pull up the grinding head forcefully, so that the plugging rod leaves the inside of the discharge hole, and the ground limestone raw material can fall into the collection box for collection. When the discharge hole is blocked, the plugging rod can be directly inserted into the discharge hole for quick dredging. The structure is reasonable, which is convenient to quickly dredge the discharge hole, thus avoiding blockage, ensuring the smoothness of discharging, and improving the grinding efficiency.
