Description

Technical Field

[0001] The present invention relates to the technical field of crushing devices, and in particular to an adjusting mechanism and a crushing device. Background Art

[0002] A rotary vertical shaft ore crusher contains a rotor equipped with hammers. Driven by a motor, the rotor rotates, driving the hammers to rotate and crush incoming ore. However, due to the hardness of the ore, the hammers wear significantly during use. This wear requires constant adjustment of the hammers' position outside the rotor to compensate for the wear.

[0003] In the existing technology, worn hammer heads need to be adjusted manually after the machine is shut down. On the one hand, there are a large number of hammer heads in the crusher, and manual adjustment takes a long time. On the other hand, the weight of a single hammer head is between 50-200kg, and manual adjustment requires a large workload to move and adjust the hammer head. According to on-site adjustment data, 2-3 hours of shutdown are required every day to adjust the hammer head, which seriously affects production efficiency. In addition, manual adjustment is not accurate enough, resulting in inconsistent hammer head positions after adjustment, which affects the uniformity of the crushed ore particle size during subsequent use.

[0048] like Figure 1-6 As shown, the present invention proposes an adjustment mechanism, comprising:

[0049] The housing 101 is arranged in the rotor 102 during the use phase. In addition, in the present invention, a plurality of bosses 900 are provided at the bottom of the housing 101, and a plurality of slots corresponding to the bosses are provided in the mounting groove on the rotor 102. After the housing 101 is installed, the housing 101 is limited by the cooperation of the bosses 900 and the slots; thereby improving the stability of the housing 101 after installation. The number of bosses 900 and the slots depends on the actual situation. In the present invention, two bosses 900 and two slots are preferably provided. In addition, a top pressing structure 200 is provided on the housing 101. When the hammer head 103 is installed, it contacts the top pressing structure 200. The top pressing structure 200 can limit the hammer head 103 to prevent the hammer head 103 from being displaced during the use phase.

[0050] The adjustment structure 300 is arranged in the housing 101, and one end passes through the top pressure structure 200 and is placed outside the housing 101; the limiting body 400 is arranged on the adjustment structure 300, and moves linearly in the housing 101 under the drive of the adjustment structure 300; during the use of the hammer head 103, as the hammer head 103 wears out, it is necessary to adjust the length of the hammer head 103 extending outside the rotor 102; specifically, by operating the adjustment structure 300, the adjustment structure 300 drives the limiting body 400 to push the hammer head 103 to move linearly, so that the hammer head 103 extends outside the rotor 102 and continues to be used; after the hammer head 103 is worn, the hammer head 103 is adjusted again by operating the adjustment structure 300 until the remaining length of the hammer head 103 is no longer sufficient for further adjustment, and the hammer head 103 is replaced;

[0051] The limiting structure 500 is arranged in the shell 101, and one end passes through the top pressure structure 200 and is placed outside the shell 101; in the supported state, the limiting body 400 is placed on the limiting structure 500, and in the disassembled state, the limiting body 400 is supported by the adjustment structure 300; when the limiting body 400 is moved by the adjustment structure 300, the limiting body 400 is placed on the limiting structure 500 and supported by the limiting structure 500, and at the same time, when the limiting body 400 is adjusted by the adjustment structure 300, the limiting body 400 slides on the limiting structure 500 and is disassembled. The hammer head 103 is pushed to move by the limiting body 400; when the position of the hammer head 103 meets the use requirements, the limiting structure 500 needs to be operated to move the top pressure structure 200 toward the hammer head 103, so that the top pressure structure 200 is tightly attached to the hammer head 103, and the hammer head 103 is limited by the top pressure structure 200; when the hammer head 103 is adjusted again, the limiting structure 500 is first operated to separate the top pressure structure 200 from the hammer head 103, and then the adjustment structure 300 is adjusted to make the limiting body 400 continue to push the hammer head 103 to move until the hammer head 103 meets the use requirements.

[0052] The technical solution of the present invention is to drive the limiting body 400 to move linearly through the adjustment structure 300 provided in the housing 101, and to limit the hammer head 103 after the limiting body 400 contacts the hammer head 103; and when the hammer head 103 is worn and cannot be used anymore, the position of the limiting body 400 in the housing 101 is changed by operating the adjustment structure 300, and the hammer head 103 is pushed by the limiting body 400 to move, so that the hammer head 103 extends out of the rotor 102 and is ready for subsequent use; at the same time, after the limiting body 400 is adjusted, the limiting body 400 is limited by the limiting structure 500 , ensuring that the adjusted hammer head 103 is in a stable state, avoiding separation from the rotor 102 during use; compared with the prior art, the technical solution of the present invention does not require the hammer head to be disassembled or moved, and the hammer head 103 can be adjusted steplessly through the adjustment structure. The adjustment speed of the hammer head 103 can be improved by cooperating with the adjustment structure 300, the limiting body 400 and the limiting structure 500, thereby reducing the overall downtime and improving production efficiency; in addition, by operating the adjustment structure 300 to change the position of the hammer head 103, the adjustment is more accurate, ensuring the uniformity of the position of the hammer head 103 after adjustment.

[0053] like Figure 3As shown, the adjustment structure 300 includes a first adjustment body 301 and an adjustment block 302. The first adjustment body 301 is arranged in the shell 101, and one end passes through the top pressure structure 200 and is placed outside the shell 101; the adjustment block 302 is sleeved on the first adjustment body 301; and moves linearly under the drive of the first adjustment body 301; the adjustment block 302 is arranged inside the limiting body 400; in the present invention, the first adjustment body 301 is preferably a screw, and the adjustment block 302 is inserted into the first adjustment body 301 and is threadedly connected to the first adjustment body 301; then, when the first adjustment body 301 is operated, the adjustment block 302 is driven to move by the threaded connection, and during the movement, the limiting body 400 is driven to move at the same time by the adjustment block 302; as shown Figure 6 As shown, the limiting body 400 is a hollow structure, so the adjustment block 302 can be set inside the limiting body 400. At the same time, with the cooperation of the limiting body 400, it can be ensured that the adjustment block 302 will not rotate simultaneously with the first adjustment body 301.

[0054] In addition, a first through hole is provided on the top-pressing structure 200, and one end of the first adjusting body 301 passes through the first through hole and is then placed outside the housing 101; thus, when adjusting the first adjusting body 301, the portion of the first adjusting body 301 outside the housing 101 is directly operated, thereby driving the limiting body 400 to move; in the present invention, the cross-section of the portion of the first adjusting body 301 outside the housing 101 is preferably hexagonal, so that during subsequent adjustments, the adjustment can be performed after connecting with the portion of the first adjusting body 301 outside the housing 101 using a hexagonal tool;

[0055] In addition, during the use phase, the first adjusting body 301 needs to be rotated. Therefore, it is necessary to ensure that the other end of the first adjusting body 301 is movably connected to the housing 101. Figure 3 As shown, in the present invention, a first rotating groove 601 is provided at one end of the shell 101, and one end of the first adjusting body 301 is arranged in the first rotating groove 601 through the first rotating body 701; in this way, the first adjusting body 301 is movably connected to the first rotating groove 601 through the first rotating body 701, and during the adjustment stage, the first rotating body 701 is placed between the first adjusting body 301 and the first rotating groove 601 for support and rotation, thereby ensuring that the first adjusting body 301 can rotate stably during the adjustment stage; in addition, considering the strength of the first rotating body 701, the preferred first rotating body 701 is a steel ball, and a quenched steel ball.

[0056] During the use stage, in order to ensure the stability between the first adjusting body 301 and the first rotating groove 601, preferably, a limiting groove is provided on the top pressure structure 200, the other end of the first adjusting body 301 is passed through the limiting groove, and an elastic body 303 is provided between the first adjusting body 301 and the limiting groove; when the first adjusting body 301 is installed, the elastic body 303 is in a compressed state and continuously applies pressure to the first adjusting body 301, so that the first adjusting body 301 always moves toward the position of the first rotating groove 601, thereby improving the stability of the connection between the first adjusting body 301 and the first rotating groove 601.

[0057] like Figure 3 、 4 As shown in FIG6 , the limiting structure 500 includes a second adjusting body 501, a first cushion block 502 and a second cushion block 503. The second adjusting body 501 is arranged in the shell 101, and one end thereof passes through the top pressure structure 200 and is placed outside the shell 101. Specifically, a second through hole is provided on the top pressure structure 200, and one end of the second adjusting body 501 passes through the second through hole and is placed outside the shell 101; the first cushion block 502 and the second cushion block 503 are relatively arranged on the second adjusting body 501; in the supporting state, the limiting body 400 is arranged on the first cushion block 502 or the second cushion block 503; in the present invention, the width of the second cushion block 503 is smaller than that of the first cushion block 503. The width of the cushion block 502 is small, and when in motion, the second cushion block 503 is inserted into the inside of the first cushion block 502, which can reasonably utilize the internal space of the shell 101 without affecting the movement of the first cushion block 502 and the second cushion block 503 between each other; and a center block is provided inside the first cushion block 502. When the limiting body 400 is at the farthest position in the shell 101 (the position farthest from the top pressure structure 200), the adjustment block 302 is placed on the center block, and the limiting body 400 is placed on both sides of the center block and the first cushion block 502 at the same time; this increases the contact area of the first cushion block 502 with the limiting body 400, thereby improving the stability of the limiting body 400;

[0058] In addition, the second adjusting body 501 is preferably a screw, and a first thread segment and a second thread segment are provided on the screw, and the thread directions of the first thread segment and the second thread segment are opposite; the first cushion block 502 is provided in the first thread segment, and the second cushion block 503 is provided in the second thread segment; when the second adjusting body 501 is operated, the first cushion block 502 and the second cushion block 503 can be moved closer or farther away from each other; and then the limiting body 400 is adjusted to support the limiting body 400 after the limiting body 400 is adjusted; as the limiting body 400 gradually moves toward the position where the top pressure structure 200 is located, When the hammer head 103 is inoperable, the first cushion block 502 and the second cushion block 503 are moved to support the limiting body 400. When the first cushion block 502 and the second cushion block 503 are moved to support the limiting body 400, the first cushion block 502 and the second cushion block 503 are moved to support the limiting body 400. The position of the limiting body 400 can be adjusted, and the hammer head 103 that cannot be used can be disassembled. The hammer head 103 is no longer restricted by the limiting body 400 and can be easily disassembled.

[0059] like Figure 3 As shown, a movable space is provided in the limiting body 400. When the limiting body 400 is supported by the first cushion block 502 or the second cushion block 503, a certain gap exists between the top of the movable space and the adjustment block 302. When the first cushion block 502 and the second cushion block 503 are no longer supporting the limiting body 400, the gap between the limiting body 400 and the adjustment block 302 can be adjusted. When the hammer head 103 is removed, the limiting body 400 no longer restricts the hammer head 103, and the hammer head 103 can be easily removed and replaced with a new hammer head 103.

[0060] like Figure 6 As shown, when the first pad 502 and the second pad 503 no longer support the limiting body 400, the disassembly of the hammer head 103 is completed, and when the new hammer head 103 is installed, the limiting body 400 is required to limit the new hammer head 103 again; therefore, it is necessary to operate the second adjusting body 501 in the opposite direction to make the first pad 502 and the second pad 503 move away from each other, and in the process of the movement of the second pad 503, the limiting body 400 is gradually raised and placed on the second pad 503 through the inclined surface 531 set at one end of the second pad 503 away from the first pad 502, and the first adjusting body 301 is operated to adjust the limiting body 400 to cooperate with the newly installed hammer head 103.

[0061] like Figure 3As shown, a second rotating groove 602 is provided at one end of the shell 101, and one end of the second adjusting body 501 is arranged in the second rotating groove 602 through the second rotating body 702; in this way, the second adjusting body 501 is movably connected to the second rotating groove 602 through the second rotating body 702, and in the adjustment stage, the second rotating body 702 is placed between the second adjusting body 501 and the second rotating groove 602 for support and rotation, thereby ensuring that the second adjusting body 501 can rotate stably in the adjustment stage; in addition, considering the strength of the second rotating body 702, the preferred second rotating body 702 is a steel ball, and a quenched steel ball.

[0062] like Figure 4-6 As shown, a slide 801 is provided on the first pad 502; a sliding hole corresponding to the slide 801 is provided on the shell 101, and a limiting slider 802 is provided in the sliding hole, and one end of the limiting slider 802 passes through the sliding hole and is placed in the slide 801; the position of the slide 801 is limited by the cooperation of the sliding hole and the limiting slider 802, and when the first pad 502 is adjusted, the stability of the first pad 502 during movement can be ensured; in the present invention, it is preferred that slides 801 are provided on both sides of the first pad 502, sliding holes are provided on both sides of the shell 101, and limiting sliders 802 are provided in the sliding holes; the stability of the first pad 502 during movement is further improved by the cooperation of the limiting sliders 802 on both sides of the shell 101; the preferred limiting slider 802 is a bolt, and is threadedly connected to the sliding hole.

[0063] like Figure 6 As shown, a caliper slider 201 is provided at one end of the top pressing structure 200, and the caliper slider 201 is adapted to one end of the top pressing structure 200; in the supporting state, the caliper slider 201 is in contact with the hammer head 103; when the hammer head 103 is installed, the caliper slider 201 is in contact with the hammer head 103, and the friction between the caliper slider 201 and the hammer head 103 is increased, and the limit body 400 is used to double-limit the hammer head 103, further reducing the possibility of the hammer head 103 being detached; and a number of friction grooves are provided on the contact surface between the caliper slider 201 and the hammer head 103, which further increases the friction between the caliper slider 201 and the hammer head 103; in addition, vertical grooves are relatively provided on the housing 101, and the bolts are connected to the caliper slider 201 after passing through the vertical grooves, and under the push of the top pressing structure 200, the caliper slider 201 is moved in the vertical groove by the bolts;

[0064] At the same time, the top pressure structure 200 is divided into a fixed part and a movable part, one end of the first adjusting body 301 is passed through the movable part, and one end of the second adjusting body 501 is passed through the fixed part; the movable part is clamped on the fixed part, and the movable part can change its position on the fixed part; the joint surface between the caliper slider 201 and the movable part is an inclined surface 531; and then when the first adjusting body 301 is operated, the movable block slides on the fixed block and generates displacement; and in the process of the movable block generating displacement, the caliper slider 201 will be moved close to or away from the hammer head 103, and then when installing or removing the hammer head 103, it can control whether the caliper slider 201 is in contact with the hammer head 103.

[0065] like Figure 7-9 As shown, the present invention also proposes a crushing device, including a cavity, a motor, a plurality of rotors 102 and a plurality of hammer heads 103; one end of the output shaft of the motor passes through the cavity and is placed in the cavity; the plurality of rotors 102 are sleeved on the output shaft of the motor; the plurality of hammer heads 103 are movably arranged on the plurality of rotors 102; and also includes a plurality of adjustment mechanisms; the housing 101 is passed through the mounting groove on the rotor 102, and the limit body 400 is engaged with the hammer head 103.

[0066] A plurality of rotors 102 are provided in the cavity. The rotors 102 have the same structure but differ in size. The rotors 102 are all connected to the output shaft of the motor. Driven by the motor, the rotors 102 rotate simultaneously and crush the ore entering the cavity. In the present invention, only one of the rotors 102 is described to save space.

[0067] Several mounting slots are provided in the rotor 102, and several hammer heads 103 and several adjustment mechanisms are respectively placed in the mounting slots, wherein the hammer head 103 is provided with a snap-fitting slot 1000, the structure of which is adapted to the limiting body 400; in addition, a first operating hole and a second operating hole are adjacently provided on the rotor 102, and the first operating hole and the second operating hole are connected to the mounting slots; in the installed state, the first operating hole and the second operating hole correspond to the first adjustment body 301 and the second adjustment body 501, respectively; in this way, an external tool can be passed through the first operating hole or the second operating hole to connect with the first adjustment body 301 or the second adjustment body 501, and operate the first adjustment body 301 or the second adjustment body 501; at the same time, when in use, the adjustment mechanism is placed inside and can be protected by the outer shell of the rotor 102 to avoid damage caused by contact between the adjustment mechanism and the ore;

[0068] like Figure 9As shown, a first inclined surface and a second inclined surface are provided on the limiting body 400, and the second inclined surface is in the direction in which the hammer head 103 extends when it is adjusted; when the hammer head 103 needs to be adjusted, the hammer head 103 is pushed to move by the second inclined surface under the drive of the first adjusting body 301; and when the hammer head 103 needs to be disassembled, the first adjusting body 301 is operated in reverse, and the limiting body 400 can be separated from the clamping groove 1000 after the transition through the first inclined surface.

[0069] like Figure 8 As shown, the number of mounting slots, hammer heads 103 and adjustment mechanisms provided on the rotor 102 are the same, and the structures are the same. To save space, only one of the mounting slots, hammer heads 103 and adjustment mechanisms is described in the present invention, and the others are not described. In addition, when making adjustments, an electric screwdriver or other tool capable of installing a hexagonal head is connected to the first adjustment body 301 or the second adjustment body 501 respectively and the operation is performed. At the same time, the adjustment distance of the hammer head 103 is determined according to the number of revolutions or time of the electric screwdriver.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
