[0060] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.
[0061] like Figure 1 to Figure 8 As shown, a hydraulic cone crusher in this embodiment includes a casing 1; the casing 1 is covered and arranged on the upper frame assembly, so as to separate the outside world from the space inside the casing 1, and on the one hand increase the aesthetic feeling of the appearance On the other hand, it reduces the erosion of impurities and improves the service life.
[0062] The upper frame assembly is movable on the casing 1; the upper frame assembly swings under the drive of the hydraulic drive assembly, so as to move relative to the lower frame assembly to crush materials.
[0063] The lower frame assembly is located in the casing 1 and is movably connected to the upper frame assembly; the lower frame assembly is movably connected to the upper frame assembly, so that the upper frame assembly drives the lower frame assembly to swing, The relative movement of the two can increase the crushing force, thereby improving the quality and efficiency of crushed materials.
[0064] The hydraulic drive assembly is connected to the upper frame assembly to drive the upper frame assembly to swing; the hydraulic drive assembly provides a power source for the work of the hydraulic cone crusher, effectively ensuring the crushing work.
[0065] The control system 11 is electrically connected to the hydraulic drive assembly; remotely controls the work of the crusher, monitors and corrects the accumulated eccentricity of the upper frame assembly during use, reduces loss, improves service life, and Adjust the size of the crushing force to adapt to different crushing needs.
[0066] Combining with the structure of this hydraulic cone crusher, the process of crushing materials will be described, in which, a crushing chamber for crushing materials is formed between the upper frame assembly and the lower frame assembly, and the swinging action of the upper frame assembly is used to The material is transferred to the lower frame assembly, so that the lower frame assembly is forced to swing.
[0067] The material enters the hydraulic cone crusher from the upper frame assembly, that is, enters the crushing cavity, and the hydraulic drive assembly drives the upper frame assembly to swing, thereby changing the inner diameter of the crushing cavity, thereby crushing the material. Under the action, the material is crushed and the size of the material is reduced. In addition, the crushing force acts on the lower frame assembly through the transmission of materials. Since the lower frame assembly is movably connected to the upper frame assembly, the lower frame assembly is forced to swing. At the moment of crushing materials, the upper frame assembly The resulting movement is opposite to the movement of the lower frame assembly, thereby increasing the absolute value of the crushing force and helping to improve the quality and effect of crushing.
[0068] The control system 11 monitors the swing of the upper frame assembly, thereby adjusting the power output by the hydraulic drive assembly, thereby adjusting the swing of the upper frame assembly, that is, adjusting the size of the crushing force.
[0069] The hydraulic cone crusher drives the lower frame assembly to swing by the upper frame assembly. During the crushing process, the upper frame assembly and the lower frame assembly form opposite movements, thereby increasing the absolute value of the crushing force. , helps to improve the quality and effect of crushing.
[0070] Maximum realization of lamination crushing; non-directional crushing track makes it easier to find the defect of the material during the crushing process, and use the defect as the crushing port for crushing, so that the least crushing energy can be used to achieve greater crushing ratio.
[0071] Compared with the existing cone crusher, it has the characteristics of larger crushing ratio, energy saving, and can start with load. For example, in the above building material crushing system, it can be changed to a jaw crusher—this hydraulic cone crusher can be crushed in two stages. Realize the original three-stage or four-stage broken effect.
[0072] In the mining industry, the finer the material, the higher the separation efficiency. Its production system is divided into crushing section, grinding section and sorting section. Grinding provides raw materials for sorting, and crushing provides raw materials for grinding. However, in the grinding section, the efficiency of grinding is relatively low, and it is necessary to provide higher power, larger equipment, more infrastructure and personnel to grind out materials that meet the sorting requirements. The concept of "more crushing and less grinding" was put forward under this condition. If the material is crushed as small as possible in the crushing section, it is possible to reduce more investment in the grinding section. The use of this hydraulic cone crusher can maximize the realization of "more crushing and less grinding", thereby saving energy and reducing crushing costs.
[0073] It is easy to understand that this hydraulic cone crusher is explained by taking the mining industry as an example, but the scope of application is not limited to the mining industry, and it can also be used for material crushing operations in building materials, cement or other suitable industries. any restrictions.

[0077] At least two exciters 23 are fixed on the upper frame 21 and are evenly distributed on the outer periphery of the wall 22 of the socket with the wall 22 of the socket as the center. The vibrator 23 acts as a vibrating machine to make the upper frame 21 and the wall 22 connected to the upper frame 21 vibrate, thereby changing the inner diameter of the crushing cavity and realizing the crushing of materials.
[0078] Optionally, according to the size of the upper frame 21, the crushing requirements, the type of the vibrator 23 and other conditions, the number of the vibrator 23 is reasonably selected, and will not be repeated here.
[0079] Now, in combination with the structure of the upper frame assembly, the work of the upper frame assembly in the crushing process is described, wherein, driven by the hydraulic drive assembly, the exciter 23 generates an exciting force, so that the upper frame 21 and the rolling mill The mortar wall 22 vibrates, and the distance between the inner wall surface of the rolling mortar wall 22 and the lower frame assembly changes, that is, the inner diameter of the crushing chamber changes, and the rolling mortar wall 22 exerts a crushing force on the material, so that the rolling mortar wall 22 and the lower frame assembly The frame assembly cooperates to squeeze and crush the material.
[0080] In a possible design, the upper frame 21 includes frame bodies divided into several layers and several connecting rods connecting adjacent frame bodies, wherein, the lower side of the bottom frame body is provided with a mounting plate 5, and the frame body The body is connected to the mounting plate 5 through the elastic member 6; to supplement the structure of the upper frame 21, in view of the height of the rolling wall 22 and the lower frame assembly, the frame body needs to be provided with multiple layers. The mounting plate 5 is used to fix the hydraulic cone crusher at the working position or connect it to other equipment. At the same time, in order to prevent the vibration of the hydraulic cone crusher from affecting the stability of the connection during crushing, a set is provided between the mounting plate 5 and the frame. The elastic member 6 absorbs shock and vibration, thereby reducing the vibration of the mounting plate 5 .

[0084] Correspondingly, the casing 1 is covered and arranged on the adjacent frame body. As for the casing 1, the casing 1 is composed of several casing plates, and the casing plates cover the adjacent frames. For example, the gap between the upper and lower frame bodies is covered by vertically arranged casing plates, and the uppermost frame body The end face is covered with shell plates arranged horizontally, which will not be described in detail here.
[0085] In the specific embodiment provided by the present invention, as an option, the hydraulic drive assembly includes: at least two motors 41 ; the motors 41 provide power to drive the hydraulic pump 42 to work.
[0086] At least two hydraulic pumps 42 are connected to the output end of the motor 41 to drive the hydraulic medium to move; the hydraulic pumps 42 drive the hydraulic medium to move to the hydraulic motor 43 , that is, to transmit force to the hydraulic motor 43 .
[0087] At least two hydraulic motors 43 are connected to the vibration exciter 23 through the coupling 12; the hydraulic motors 43 apply force to the vibration exciter 23 to make the upper frame assembly swing. The coupling 12 plays the role of overload protection and ensures the connection between the hydraulic motor 43 and the vibrator 23 .
[0088] Optionally, any suitable model can be selected for the shaft coupling 12, which is not limited in the present invention.
[0089] Wherein, the motor 41 , the hydraulic pump 42 , the hydraulic motor 43 and the vibration exciter 23 are provided in one-to-one correspondence. It is easy to understand that the respective models of the motor 41 , the hydraulic pump 42 and the hydraulic motor 43 are determined according to actual working conditions, and will not be repeated here.
[0090] The operation of the hydraulic drive assembly will be described, that is, the motor 41 drives the hydraulic pump 42 so that the hydraulic medium enters the hydraulic motor 43 , so that the hydraulic motor 43 and the vibrator 23 work.

[0093] At this time, for the force applied by a single vibrator 23, the direction of the force changes after the vibrator 23 turns, so that the magnitude and direction of the crushing force change, that is, the crushing effect of the crushing force does not meet expectations, that is, the material The particle size after being crushed by this hydraulic cone crusher does not meet the requirements.
[0094] In this regard, it is improved by setting the control system 11, that is, the angular displacement sensor 13 detects the eccentric angle of the exciter 23 and transmits it to the control terminal, and the control terminal will compare the eccentric angle with the preset angle to obtain the angle difference , when the angle difference is within the set range, that is, the rotation angle of the vibrator 23 is within an acceptable range, there is no need to adjust the position of the vibrator 23 . On the contrary, when the angle difference exceeds the set range, the position of the vibrator 23 needs to be adjusted.
[0095] Specifically, the process of adjusting the position of the vibrator 23 is as follows. The control terminal sends instructions to the hydraulic pump 42 to change the outflow of the hydraulic medium of the hydraulic pump 42, so that the hydraulic motor 43 drives the vibrator 23 to rotate, thereby adjusting the exciter. The angle of the vibrator 23 is within the set range. At the same time, the angular displacement sensor 13 transmits the eccentric angle of the exciter 23 to the control terminal for feedback control.
