本发明属于破碎机技术领域，具体涉及一种精确调整破碎机排料口的方法。The invention belongs to the technical field of crushers, and in particular relates to a method for accurately adjusting the discharge port of a crusher.
背景技术Background technique
破碎机被广泛应用于矿山、建筑、水泥、铁路、垃圾处理等行业。破碎机排料口的精度不仅对于产品的质量、产量有很大的影响，而且对破碎机的可靠性和寿命影响极大。破碎机在工作过程中，由于矿料成分的变化和排料口的磨损，排料口的大小是经常变化的，因此需要经常调整排料口的大小。Crusher is widely used in mining, construction, cement, railway, garbage disposal and other industries. The accuracy of the crusher's discharge port not only has a great impact on the quality and output of the product, but also has a great impact on the reliability and life of the crusher. During the working process of the crusher, due to the change of mineral composition and the wear of the discharge port, the size of the discharge port changes frequently, so it is necessary to adjust the size of the discharge port frequently.
当前，大部分破碎机的排料口依靠人工调整定期测量和调整；工作中排料口变动依靠弹簧机构完成过载排料和复位。部分厂家开发设计基于液压系统的排料口自动电控系统，其液压管路的控制多用开关阀，在动态调节过程中，常常出现排料口过大或过小现象，严重时，系统出现震荡现象，排料口不停的调节。严重影响产品的质量和产量。部分厂家采用节流阀减少进油和排油流量，满足精度调节要求，防止排料口震荡的现象，但又延长调整时间，产品的不合格率增加，降低了设备的产量。综上，现有的调节方法，都没能很好的解决实现快速调节和高精度控制的问题。在中国专利CN207680772U、CN108150465A和CN107597408A中对反击式破碎机和圆锥破碎机排料口自动调节的机械结构、控制机构和控制策略都给出解决方法，但仍旧没有解决排料口快速调节和高精度调节的问题。At present, the discharge port of most crushers relies on manual adjustment to measure and adjust regularly; the change of the discharge port during work relies on the spring mechanism to complete the overload discharge and reset. Some manufacturers develop and design the automatic electric control system for the discharge port based on the hydraulic system, and the control of the hydraulic pipeline is multi-purpose switch valve. During the dynamic adjustment process, the discharge port is often too large or too small. Phenomenon, the discharge port is constantly adjusted. Seriously affect the quality and yield of the product. Some manufacturers use throttle valves to reduce the flow of oil in and out, to meet the requirements of precision adjustment and prevent the phenomenon of vibration of the discharge port, but prolong the adjustment time, increase the failure rate of products, and reduce the output of the equipment. To sum up, none of the existing adjustment methods can well solve the problem of realizing rapid adjustment and high-precision control. In Chinese patents CN207680772U, CN108150465A and CN107597408A, solutions are given for the mechanical structure, control mechanism and control strategy of the automatic adjustment of the discharge port of the impact crusher and cone crusher, but there is still no solution to the rapid adjustment and high precision of the discharge port. adjustment problem.
发明内容SUMMARY OF THE INVENTION

Movement, adjust the relative position between the movable part of the discharge port and the static part of the discharge port, so as to adjust the size of the discharge port; the hydraulic system is provided with an electromagnetic proportional valve to control the movement speed of the hydraulic cylinder; the hydraulic system has the ability to detect the discharge The displacement sensor of the relative position of the port is installed in the hydraulic cylinder; in order to protect the crusher and the hydraulic system of the crusher, a pressure sensor is installed at the oil inlet of the hydraulic cylinder to detect the pressure of the oil inlet; electromagnetic proportional valve, displacement sensor and The pressure sensors are all signal-connected to the electronic control system; the electronic control system includes an intelligent controller;
对破碎机排料口的控制方法如下：The control method of the crusher discharge port is as follows:
不带载调节方式为：启动电控系统，电控系统输出最大控制信号，电磁比例阀开到最大流量，液压油缸以最大速度运动；电控系统接收位移传感器传输的数值，并将该数值与电控系统设定的减速位置数值相比较，当位移传感器输出的数值大于或等于电控系统的设定的减速位置数值时，电控系统逐步减小输出控制信号直至设定进给信号，电磁比例阀开度减小到设定开度，液压油缸在设定的低速下带动排料口可动部分慢慢上升；当电控系统检测到位移传感器传输过来的数值与设定的排料口位置一致时，电控系统停止对电磁比例阀供电，排料口可动部分到达设定的位置；The adjustment method without load is: start the electronic control system, the electronic control system outputs the maximum control signal, the electromagnetic proportional valve opens to the maximum flow, and the hydraulic cylinder moves at the maximum speed; the electronic control system receives the value transmitted by the displacement sensor, and compares the value with the value. Compared with the deceleration position value set by the electronic control system, when the output value of the displacement sensor is greater than or equal to the deceleration position value set by the electronic control system, the electronic control system gradually reduces the output control signal until the feed signal is set. The opening of the proportional valve is reduced to the set opening, and the hydraulic cylinder drives the movable part of the discharge port to rise slowly at the set low speed; when the electronic control system detects the value transmitted by the displacement sensor and the set discharge port When the positions are consistent, the electronic control system stops powering the electromagnetic proportional valve, and the movable part of the discharge port reaches the set position;
带载调节方式为：破碎机在工作过程中，当电控系统检测到压力传感器输出值快速增大时，电控系统控制液压油缸快速回缩，排料口快速增大，释放出难以破碎的物料；然后电控系统依据位移传感器的输出信号，判断排料口可动部分的位置，给定电磁比例阀的开度：电控系统接收位移传感器传输的数值，并将该数值与电控系统设定的减速位置数值相比较，当位移传感器输出的数值小于设定的减速位置数值时，电磁比例阀开度最大，液压油缸快速运动；当位移传感器输出的数值大于或等于电控系统的设定的减速位置数值时，电控系统逐步减小输出控制信号直至设定进给信号，电磁比例阀开度减小到设定开度，液压油缸在设定的低速下带动排料口可动部分慢慢上升；当电控系统检测到位移传感器传输过来的数值与设定的排料口位置一致时，电控系统停止对电磁比例阀供电，排料口到达设定排料口位置。The load adjustment method is: during the working process of the crusher, when the electronic control system detects that the output value of the pressure sensor increases rapidly, the electronic control system controls the hydraulic cylinder to retract rapidly, the discharge port increases rapidly, and releases the hard-to-break material. Then the electronic control system judges the position of the movable part of the discharge port according to the output signal of the displacement sensor, and gives the opening of the electromagnetic proportional valve: the electronic control system receives the value transmitted by the displacement sensor, and compares the value with the electronic control system Compared with the set deceleration position value, when the output value of the displacement sensor is less than the set value of the deceleration position, the opening of the electromagnetic proportional valve is the largest, and the hydraulic cylinder moves rapidly; when the output value of the displacement sensor is greater than or equal to the setting of the electronic control system. When the value of the deceleration position is set, the electronic control system gradually reduces the output control signal until the feed signal is set, the opening of the electromagnetic proportional valve is reduced to the set opening, and the hydraulic cylinder drives the discharge port to move at the set low speed. The part rises slowly; when the electronic control system detects that the value transmitted by the displacement sensor is consistent with the set discharge port position, the electronic control system stops power supply to the electromagnetic proportional valve, and the discharge port reaches the set discharge port position.
进一步地，所述电磁比例阀的控制信号采用连续变化的模拟信号控制或者离散的电信号控制。Further, the control signal of the electromagnetic proportional valve is controlled by a continuously changing analog signal or a discrete electrical signal.

If the electronic control system receives the travel limit switch, the power of the crushing motor reaches the set When the value and pressure sensor reach any trigger signal in the set value, the hydraulic cylinder stops moving forward and waits for manual or automatic zero-point confirmation.
进一步地，液压系统的供油管路和回油管路设有所述电磁比例阀。Further, the oil supply pipeline and the oil return pipeline of the hydraulic system are provided with the electromagnetic proportional valve.
