Description

Technical Field

[0001] The utility model relates to the field of crusher equipment, in particular to a pad structure for adjusting the distance between rollers of a high-calcium stone three-eight-block crusher. Background Art

[0002] High-calcium stone is also called limestone. Its main component is calcium carbonate. Limestone is a raw material used in large quantities in building materials and industry. Limestone can also be directly processed into stone and burned into quicklime. Limestone is also the main raw material for producing glass. The materials for making glass are limestone, quartz sand, soda ash, etc. These materials are melted at high temperatures to produce glass; in industrial production, limestone is also a solvent and vein-removing stone for iron smelting. Quicklime is used here. Quicklime can be used as a slag-making material to filter out harmful impurities such as sulfur and phosphorus. High-calcium stone 38 pieces refer to pieces with a size of 3-8cm. In the production process of high-calcium stone, in order to obtain pieces with a size of 3-8cm, it is usually necessary to adjust the distance between the rollers of the crusher to adapt to the production of high-calcium stone products of different sizes. The rotating slider of the current crusher's movable shaft is fixed to the crusher body by bolts inserted into the waist-shaped hole. The length of the waist-shaped hole is the adjustable distance of the movable shaft. During the use of the crusher, the movable shaft is easily moved sideways due to the extrusion force, resulting in errors, and the fixation is not firm enough. In the adjustment process, it is necessary to first loosen the fixing bolts of the rotating slider, and then adjust the position of the rotating slider and the fixing bolts in the waist-shaped hole to change the crushing roller spacing, and then tighten the bolts again to complete the adjustment, which is cumbersome.

[0026] See also Figure 1-Figure 6 As shown, the utility model provides a pad structure for adjusting the roller spacing of a high-calcium stone three-eight-block crusher, comprising a base 1 and two sets of top frames 2, the two sets of top frames 2 are longitudinally arranged on the top side of the base 1, the two sets of top frames 2 cooperate with the base 1 to form two horizontally extending tracks, a movable shaft 4 is longitudinally penetrated in the middle of the track, both ends of the movable shaft 4 are rotatably matched with sliders 7 that slide and match the track laterally, and a pad frame 8 supporting the slider 7 is arranged on the outside of the base 1;

[0027] Two groups of rotating ears 102 are arranged on both sides of the pad frame 8 on the top side of the base 1. The pad frame 8 is a C-shaped frame with two groups of sliders 7 distributed at both ends and extending horizontally. Vertical plates 801 supporting the sliders 7 are fixed at both ends of the pad frame 8. A laterally extending transmission cylinder 802 is threadedly engaged in the middle part of the pad frame 8. The transmission cylinder 802 and the rotating ear 102 are rotationally engaged through a thrust bearing to ensure that the lateral position of the transmission cylinder 802 in the middle part of the rotating ear 102 will not be offset.

[0029] A guide rod 702 is fixed on the side of the slider 7 close to the vertical plate 801, which runs through the vertical plate 801 horizontally. The guide rod 702 is in clearance with the vertical plate 801. An end block is fixed on the outer end of the guide rod 702 to prevent the vertical plate 801 from detaching from the guide rod 702. A compression spring 703 is sleeved on the outer side of the guide rod 702, with the two ends respectively pressing against the vertical plate 801 and the slider 7. The guide rod 702 is used in conjunction with the compression spring 703 as a connecting mechanism between the vertical plate 801 and the slider 7 to achieve floating support of the pad frame 8 on the slider 7, ensuring that the movable shaft 4 can move laterally under the support of the slider 7 when receiving the crushing extrusion force, so as to avoid damage caused by the fixed position of the movable shaft 4, and the slider 7 can be supported to reset by the compression spring 703, thereby ensuring the stability of crushing;

[0030] The operating assembly 9 includes a synchronization rod 901 that penetrates the transmission cylinder 802 and is adapted to the shape of the synchronization groove 802a, ensuring that the synchronization rod 901 can drive the transmission cylinder 802 to rotate.
