[0002] In people's daily life, the main component of limestone is calcium carbonate. In modern industry, limestone is the main raw material for manufacturing lime, cement, and calcium carbide; in the metallurgical industry, limestone is an indispensable flux limestone, and limestone is widely used in industries such as water ash, smelting, cement, chemical industry, power plant desulfurization, and papermaking. Moreover, with the development of science and technology, it can also replace plastics to make pipes and packaging materials. As a new type of environmental protection raw material, the market demand for limestone is increasing year by year.

[0003] The existing jaw crusher device for limestone raw materials mainly has the problem of not being able to perform secondary processing and crushing on limestone raw materials during use. Therefore, when the limestone is crushed by the jaw crusher, if smaller-sized limestone raw materials are required, other methods have to be used for processing, which is time-consuming and laborious, and increases the additional costs of the enterprise.

[0012] 1. For the jaw crusher for limestone raw material pretreatment, through the combined use of the second motor and the rolling rod, the second motor is controlled to work by the controller. The power output shaft of the second motor drives the rolling rod to rotate on the inner wall of the storage cylinder, so as to perform secondary rolling operation on the crushed limestone raw materials falling into the storage cylinder, making the volume of the limestone raw materials more crushed and smaller, and further reducing the volume diameter of the limestone raw materials to obtain smaller-sized limestone raw materials.

[0013] 2. For the jaw crusher for limestone raw material pretreatment, through the combined use of the T-shaped slider and the T-shaped sliding groove, when it is not necessary to perform secondary rolling operation on the limestone raw materials, only by sliding connection of the T-shaped slider and the T-shaped sliding groove, pull the storage cylinder outwards. The T-shaped slider slides outwards on the inner wall of the T-shaped sliding groove, and then the storage cylinder can be removed. At this time, the crushed limestone raw materials can directly fall. Secondly, by using a layer of anti-slip pads laid at the bottom of the support legs, when the device is operating, the sliding phenomenon of the device can be avoided, improving the stability of the device.

[0021] In a preferred implementation manner, the rolling rod 19 is located inside the storage cylinder 17 and is rotatably connected to the inner wall of the storage cylinder 17. By using the setting of the rolling rod 19, the crushed limestone raw materials can be further rolled, so as to meet the requirements for finer limestone raw materials.

[0022] In a preferred implementation manner, support legs 20 are fixedly installed at the bottom of the underframe 2, and the number of the support legs 20 is four. A layer of anti-slip pads is laid at the bottom of the support legs 20. By setting the support legs 20, the device can operate stably, and the anti-slip pads can improve the anti-slip performance of the device.

[0023] In a preferred embodiment, a circular groove penetrates through the bottom of the storage cylinder 17, and the power output shaft of the second motor 18 is rotatably connected to the inner wall of the circular groove. By providing the circular groove, the power output shaft of the second motor 18 can smoothly drive the rolling rod 19 to perform a secondary rolling operation on the crushed limestone raw material falling into the storage cylinder 17.

[0024] In a preferred embodiment, a controller is provided on the outer side of the wall plate 1. Both the first motor 5 and the second motor 18 are electrically connected to the controller.

[0026] Working principle: When the device needs to be used, first, the limestone raw material can be poured into the crushing chamber between the fixed jaw plate 10 and the moving jaw plate 12. Subsequently, the controller is used to control the first motor 5 to work, so that the power output shaft of the first motor 5 drives the belt main body 6 to rotate. Through the transmission connection between the belt main body 6 and the belt pulley 7, the belt pulley 7 is driven together. By the rotation of the belt pulley 7, the eccentric shaft 8 rotates, and then the moving jaw plate 12 moves, so as to perform a crushing operation on the limestone raw material located in the crushing chamber. Subsequently, the crushed limestone raw material falls into the inner wall of the storage cylinder 17. At this time, the controller can be used to control the second motor 18 to work. The power output shaft of the second motor 18 drives the rolling rod 19 to rotate on the inner wall of the storage cylinder 17, so as to perform a secondary rolling operation on the crushed limestone raw material falling into the storage cylinder 17, making the volume of the limestone raw material more crushed and smaller. When the secondary rolling operation on the limestone raw material is not required, only by the sliding connection between the T-shaped slider 16 and the T-shaped sliding groove 21, the storage cylinder 17 is pulled outwards. By the T-shaped slider 16 sliding outwards on the inner wall of the T-shaped sliding groove 21, the storage cylinder 17 can be removed, and at this time, the crushed limestone raw material can directly fall.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
