Description
Technical Field
[0001] The utility model relates to the field of high-calcium stone crushing equipment, and particularly relates to a three-eight block double-toothed roll crusher for high-calcium stones. Background Technique
[0002] High-calcium stones are widely used in building materials and industry. High-calcium stones can be processed into stones and burned into quicklime. Quicklime becomes slaked lime when it absorbs moisture or is added with water. Slaked lime can be called calcium hydroxide. Slaked lime is widely used in the construction industry after being prepared into lime slurry, lime paste, etc. In the primary processing of high-calcium stones, it is first necessary to break them from a large block structure into small pieces suitable for subsequent processing. The three-eight blocks of high-calcium stones refer to fragments with a length dimension of 3-8 cm. In the production process of high-calcium stones, to obtain fragments with a size of 3-8 cm, it is usually necessary to adjust the distance between the two toothed rolls. At present, when the double-toothed roll crusher is in use, the positions of the two groups of toothed rolls are in a fixed state. During the crushing process, the crushing rolls are easily stuck due to the too large volume of the material, and the impact pressure on the rotating position of the toothed rolls is relatively large, which easily causes the shaft rods of the toothed rolls to bend and deform, and is not conducive to the long-term use of the crusher. Content of the Utility Model
[0003] The purpose of the utility model is to provide a three-eight block double-toothed roll crusher for high-calcium stones to solve the above problems. The movable toothed roll is set as a floating structure, and the two side buffer frames are used as elastic support structures, which can conveniently adjust the distance between the two groups of toothed rolls to adapt to the crushing requirements of high-calcium stones of different sizes; at the same time, the movable toothed roll can move horizontally to avoid the drawback that the position of the toothed roll of the current crusher is fixed and is easily bent by impact, improve the structural safety of the crusher in use, and is conducive to realizing long-term use, as described in detail below.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A three-eight block double-toothed roll crusher for high-calcium stones provided by the utility model includes a frame and an upper pressure seat. The upper pressure seat is fixed to the top side of the frame. A toothed roll guard is arranged inside the frame. A fixed toothed roll and a movable toothed roll are arranged inside the toothed roll guard. A first driving part is arranged in front of the frame, and a universal coupling for drivingly connecting the movable toothed roll is arranged at the output end of the first driving part. A buffer frame is arranged on the top of the frame near one side of the movable toothed roll;
[0006] A longitudinally extending movable shaft is coaxially fixed in the middle of the movable toothed roll. Movable seats are rotatably fitted on the outer sides of both ends of the movable shaft. The movable seats are horizontally slidably arranged between the frame and the upper pressure seat. A fixed shaft longitudinally passing through the toothed roll guard is coaxially fixed in the middle of the fixed toothed roll. Fixed seats fixed to the top side of the frame are rotatably arranged at both ends of the fixed shaft. A second driving part for driving the fixed shaft to rotate is arranged in front of the frame.
[0007] When using the above-mentioned high-calcium stone three-eight block double-toothed roll crusher, the material to be crushed is fed into the inner sides of the fixed toothed roll and the movable toothed roll through the feed inlet of the toothed roll guard. The first driving part drives the movable shaft and the movable toothed roll to rotate through a universal coupling. At the same time, the second driving part directly drives the fixed shaft and the fixed toothed roll to rotate. By using the reverse rotation of the fixed toothed roll and the movable toothed roll, the material is squeezed and crushed downward. At the same time, two sets of buffer frames respectively support two sets of movable seats at both ends of the movable roll to ensure that the movable toothed roll can translate horizontally, realizing the change of the distance between the movable toothed roll and the fixed toothed roll. Thus, during the material crushing process, the movable toothed roll is kept in a horizontal movable state, and the movable seat and the movable toothed roll are positioned by springs to be able to improve the deformation problem caused by the long-term impact on the shaft rod. When it is necessary to adjust the distance between the two toothed rolls according to the crushing particle size of different materials, the main oil cylinder drives the buffer plate to move horizontally, changing the pushing position of the buffer plate on the spring and the movable seat, and then realizing the process of adjusting the distance between the movable toothed roll and the fixed toothed roll.
[0008] Preferably, a middle support for separating the fixed toothed roll and the movable toothed roll is fixed in the middle of the top side of the frame, and a secondary oil cylinder with a telescopic end facing the side of the movable seat is fixed in the middle of the middle support.
[0009] Preferably, a tail seat for supporting the upper pressing seat is fixed on the top side of the frame, and the top side of the tail seat is fixedly connected to the bottom side of the upper pressing seat by bolts.
[0010] Preferably, a feed inlet penetrates vertically through the top side of the toothed roll guard, and a discharge outlet is communicated corresponding to the feed inlet at the bottom side of the toothed roll guard. A receiving hole for the movable shaft to pass through and move horizontally is longitudinally communicated in the middle of the toothed roll guard, and the receiving hole is of a waist-shaped hole structure extending horizontally.
[0011] Preferably, the buffer frame includes an oil cylinder seat fixed between the frame and the upper pressing seat. A main oil cylinder extending horizontally is fixed in the middle of the oil cylinder seat, and a buffer plate is fixed to the outer telescopic end of the main oil cylinder.
[0012] Preferably, two groups of horizontally extending limit columns are arranged vertically on the side of the movable seat close to the buffer plate. A horizontally extending spring is fixed to the outside of the buffer plate, and the outer end of the spring is sleeved outside the limit column and abuts against the movable seat.
[0013] Preferably, cross couplings are arranged at both ends of the universal coupling, and the universal coupling realizes the transmission connection between the first driving part and the movable toothed roll through two groups of cross couplings.
[0014] The beneficial effects are as follows: By setting the movable tooth roller as a floating structure and using the two-side buffer frames as elastic support structures, the present utility model can conveniently adjust the distance between the two groups of tooth rollers to adapt to the crushing requirements of high-calcium stones of different sizes.
[0015] At the same time, the movable tooth roller can move horizontally to avoid the drawback that the position of the tooth roller of the current crusher is fixed and is easily impacted and bent, improve the structural safety of the crusher in use, and is conducive to long-term use.

All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope protected by the present utility model.
[0026] Refer to Figures 1-6 As shown, the present utility model provides a high-calcium stone three-eight block double-tooth roll crusher, which includes a frame 1 and an upper pressure seat 2. The upper pressure seat 2 is fixed to the top side of the frame 1. A tooth roll guard 3 is arranged inside the frame 1.

A universal coupling 7 for drivingly connecting the movable tooth roll 5 is arranged at the output end of the first driving part 6. A buffer frame 8 is arranged on the top side of the frame 1 near the movable tooth roll 5. The buffer frame 8 is used to support the movable tooth roll 5, so as to adjust the lateral position of the movable tooth roll 5 to adapt to the crushing of materials with different crushing particle size requirements.
[0027] A longitudinally extending movable shaft 501 is coaxially fixed in the middle of the movable tooth roll 5. Movable seats 502 are rotatably fitted on the outer sides of both ends of the movable shaft 501. The movable seats 502 are slidably arranged transversely between the frame 1 and the upper pressure seat 2. A fixed shaft 401 longitudinally passing through the tooth roll guard 3 is coaxially fixed in the middle of the fixed tooth roll 4. Fixed seats 402 fixed to the top side of the frame 1 are rotatably arranged at both ends of the fixed shaft 401. The fixed seats 402 are used to position the fixed shaft 401 and support the rotation of the fixed shaft 401 and the fixed tooth roll 4. A second driving part 9 for driving the fixed shaft 401 to rotate is arranged in front of the frame 1.
[0028] As an optional implementation manner, a middle support 101 for separating the fixed tooth roll 4 and the movable tooth roll 5 is fixed to the middle of the top side of the frame 1. A sub-cylinder 102 with a telescopic end facing the side of the movable seat 502 is fixed to the middle of the middle support 101. The sub-cylinder 102 is used to extend out of the middle support 101 to limit the lateral sliding distance of the movable seat 502, that is, to limit the distance between the fixed tooth roll 4 and the movable tooth roll 5.
[0029] A tail seat 103 for supporting the upper pressure seat 2 is fixed to the top side of the frame 1. The top side of the tail seat 103 is fixedly connected to the bottom side of the upper pressure seat 2 by bolts. A feed inlet 301 penetrates vertically through the top side of the tooth roll guard 3. A discharge outlet corresponding to the feed inlet 301 penetrates through the bottom side of the tooth roll guard 3. The crushed material is discharged downward along the discharge outlet. A receiving hole 302 for accommodating the movable shaft 501 to pass through and move transversely is longitudinally penetrated through the middle of the tooth roll guard 3. The receiving hole 302 is a waist-shaped hole structure extending transversely, ensuring that the receiving hole 302 can accommodate the movable tooth roll 5 and the transverse movement of the movable shaft 501, and meeting the distance adjustment requirements between the movable tooth roll 5 and the fixed tooth roll 4.
[0030] The buffer frame 8 includes an oil cylinder seat 801 fixed between the frame 1 and the upper pressure seat 2. A horizontally extending main oil cylinder 802 is fixed in the middle of the oil cylinder seat 801. A buffer plate 803 is fixed to the telescopic end outside the main oil cylinder 802. Two groups of horizontally extending limit columns 503 are arranged vertically on the side of the movable seat 502 close to the buffer plate 803.

The outer end of the spring 804 is sleeved outside the limit column 503 and abuts against the movable seat 502, so as to support the buffer plate 803 to move horizontally through the main oil cylinder 802, and then use the spring 804 outside the buffer plate 803 to push the movable seat 502 to move horizontally, realizing the adjustment of the installation position of the movable tooth roller 5, so as to adapt to the crushing needs of materials with different particle sizes;
[0031] Cross couplings 701 are provided at both ends of the universal coupling 7. The universal coupling 7 realizes the transmission connection between the first driving part 6 and the movable tooth roller 5 through the two groups of cross couplings 701, ensuring the transmission connection state between the first driving part 6 and the movable shaft 501 when the movable tooth roller 5 moves horizontally to different positions.
[0032] With the above structure, during use, the material to be crushed is put into the inner sides of the fixed tooth roller 4 and the movable tooth roller 5 through the feed port 301 of the tooth roller guard 3. The first driving part 6 drives the movable shaft 501 and the movable tooth roller 5 to rotate through the universal coupling 7. At the same time, the second driving part 9 directly drives the fixed shaft 401 and the fixed tooth roller 4 to rotate, and uses the reverse rotation of the fixed tooth roller 4 and the movable tooth roller 5 to squeeze and crush the material downward. At the same time, the two buffer frames 8 respectively support the two movable seats 502 at both ends of the movable roller, ensuring that the movable tooth roller 5 can move horizontally, realizing the change of the distance between the movable tooth roller 5 and the fixed tooth roller 4, so as to keep the movable tooth roller 5 in a horizontal moving state during the material crushing process, and realizing positioning by supporting the movable seat 502 and the movable tooth roller 5 through the spring 804, so as to improve the deformation problem caused by the long-term impact on the shaft rod; when it is necessary to adjust the distance between the two tooth rollers according to the crushing particle size of different materials, the main oil cylinder 802 drives the buffer plate 803 to move horizontally, changing the pushing position of the buffer plate 803 on the spring 804 and the movable seat 502, and then realizing the process of adjusting the distance between the movable tooth roller 5 and the fixed tooth roller 4;
[0033] By setting the movable tooth roller 5 as a floating structure and using the two buffer frames 8 as elastic support structures, it is convenient to adjust the distance between the two tooth rollers to adapt to the crushing requirements of different sizes of high-calcium stones;
[0034] At the same time, the movable tooth roller 5 can move horizontally to avoid the current drawback that the position of the tooth roller of the crusher is fixed and is prone to be impacted and bent, improving the use safety of the crusher structure and being beneficial to long-term use.
