[0003] Mobile crushing equipment includes a traveling device and a crushing device. Existing mobile crushing and screening equipment typically uses a diesel engine as its power source, with a hydraulic system driving a hydraulic motor to power the wheel-side reducer, thus enabling the mobile crushing and screening equipment to move. Simultaneously, the diesel engine also needs to provide power to the crushing device to ensure the overall operation of the mobile crushing and screening equipment.

[0004] Because diesel engines are used as the power source, they exacerbate environmental and noise pollution during operation, while also increasing production costs. Due to the harsh working environment of mobile crushing and screening equipment, hydraulic systems frequently experience malfunctions such as oil circuit contamination, oil circuit blockage, and valve damage. Troubleshooting and resolving these malfunctions on-site is difficult, increasing maintenance cycles and costs, and also leading to production losses.

[0005] Therefore, there is an urgent need for a mobile crushing and screening device to solve the above problems. Utility Model Content

[0048] like Figure 1 As shown, this embodiment provides a crushing and screening equipment for crushing, screening, and removing iron from mining sand and gravel aggregates, construction waste, etc. The crushing and screening equipment includes a main body 10, which includes a crushing device 12 and / or a screening device. The crushing device 12 is used to crush the materials into blocks, granules, or powder. The screening device is used to separate mixtures of different particle sizes into different grades, ensuring that each grade of material meets the requirements for subsequent processing or use. Screening can remove excessively large or small particles from the material, ensuring the uniformity of product particle size and quality stability.

[0049] Furthermore, the main body of the equipment also includes a vehicle body 13 and a traveling device 11. The crushing device 12 is mounted on the vehicle body 13, the screening device is mounted on the vehicle body, and the traveling device 11 is mounted on the vehicle body 13 and can drive the vehicle body 13 and the crushing device 12 on it to move, so that the crushing device 12 and the screening device can be quickly moved to different work locations according to the operation requirements, without being restricted by the site, thus improving production efficiency.

[0050] In this embodiment, the main body 10 is an integrated crushing and screening machine, meaning that the main body 10 includes a crushing device 12 and a screening device, thus enabling the main body 10 to both crush and screen materials. In other embodiments, the main body 10 includes the crushing device 12, meaning that the main body 10 can only crush materials. In another optional embodiment, the main body 10 includes a screening device, meaning that the main body 10 can only screen materials.

[0051] Existing mobile crushing and screening equipment typically uses a diesel engine as its power source, with a hydraulic system driving a hydraulic motor to power the wheel-side reducer and thus the traveling mechanism. Simultaneously, the diesel engine must also provide power to the crushing unit to ensure the overall operation of the mobile crushing and screening equipment. However, using a diesel engine as the power source exacerbates environmental and noise pollution during operation, while also increasing production costs. Due to the harsh working environment of mobile crushing and screening equipment, hydraulic systems frequently experience malfunctions such as oil circuit contamination, blockages, and valve damage. Troubleshooting and resolving these issues on-site is difficult, increasing maintenance cycles and costs, and ultimately leading to production losses.

[0052] To solve the above problems, such as Figure 1 and Figure 2 As shown, the mobile crushing and screening equipment 100 provided in this embodiment also includes a battery system 20 and / or a terminal block 30. The battery system 20 includes an energy storage battery 21 and a charging interface 22. The energy storage battery 21 is configured to supply power to the main body 10 of the equipment. The charging interface 22 is provided on the main body 10 of the equipment and is connected to the energy storage battery 21. The charging pile can charge the energy storage battery 21 through the charging interface 22. The main body 10 of the equipment and the energy storage battery 21 are electrically connected to the terminal block 30, and the terminal block 30 can be connected to the power grid.

[0053] The mobile crushing and screening equipment 100 provided in this embodiment supplies power to the main body 10 via an energy storage battery 21. The main body 10 utilizes the electrical energy provided by the energy storage battery 21 to complete preset actions, offering advantages such as simple structure, reduced emissions, and low noise. Furthermore, the energy storage battery 21 has a simple structure and low maintenance costs, reducing equipment maintenance and usage costs. By providing a charging interface 22, a charging pile can charge the energy storage battery 21, enabling multiple charge-discharge cycles and reducing usage costs. By providing a terminal block 30 and electrically connecting the main body 10 and the energy storage battery 21 to the terminal block 30, the terminal block 30 can be used to charge the energy storage battery 21 and also to provide power to the main body 10. When the energy storage battery 21 is depleted, the main body 10 can still use the electrical energy connected to the power grid via the terminal block 30 for power. This diversified power source can adapt to various usage scenarios.

[0054] Optionally, the charging station can be a DC charging station or an AC charging station to improve the convenience of charging the energy storage battery 21 and to flexibly choose the charging method.

[0055] Optionally, the power grid is 380V AC mains power to provide strong power to the main body of the equipment 10, thereby improving crushing efficiency and production capacity.

[0056] When the AC charging pile or terminal 30 is used to charge the energy storage battery 21, the AC charging pile or terminal 30 charges the energy storage battery 21 through the charging control system 40. The charging control system 40 performs AC / DC conversion on the AC power and then charges the energy storage battery 21 to ensure the stability and reliability of the charging.

[0057] Optionally, the energy storage battery 21 includes at least one battery module and a battery management system. The battery module is used to supply power to the main body of the device 10. The battery management system is electrically connected to the battery module. Through the battery management system, the remaining power, temperature, output voltage and other technical parameters of the battery module can be monitored in real time, and the technical parameters can be output and displayed for staff to view. It can also provide safety protection for the battery module to prevent overcharging, over-discharging, short circuit and other situations, thereby improving the safety performance of the battery module.

[0058] Optionally, the battery module includes multiple battery cells, which are connected in a mixed-connection configuration to improve the capacity and voltage of the battery module. This mixed-connection configuration involves both series and parallel connections among the multiple battery cells.

[0059] Specifically, the battery cell is a lithium battery, which has advantages such as light weight, high energy density, and fast charging speed. Optionally, the battery cell can be a lithium cobalt oxide battery, a lithium manganese oxide battery, a lithium iron phosphate battery, or a ternary lithium battery.

[0060] Optionally, the terminal block 30 is connected to the power grid via a cable of a certain length, which can increase the range of motion of the mobile crushing and screening equipment 100 so as to complete the operation tasks in more areas under limited power conditions.

[0061] Optionally, the cable length is L, where 10m ≤ L ≤ 100m. This size limitation satisfies the movement requirements of the mobile crushing and screening equipment 100 within a certain area without causing tangling or other problems due to excessive cable length. For example, the cable length L can be 10m, 20m, 30m, 40m, 50m, 60m, 70m, 80m, 90m, or 100m. In other embodiments, the cable length is not limited to these values, and operators can choose an appropriate length based on actual needs.

[0062] In this embodiment, the walking device 11 includes a motor and a track walking mechanism. The track walking mechanism includes a drive wheel 111, a guide wheel 113, and a track 112. The motor is mounted on the vehicle body 13. The energy storage battery 21 and the terminal block 30 are respectively connected to the motor. The drive wheel 111 is rotatably connected to the vehicle body 13. The outer circumference of the drive wheel 111 has an external gear. The drive wheel 111 and the guide wheel 113 together tension the track 112. The external gear meshes with the track 112. During operation, the energy storage battery 21 or the terminal block 30 is connected to the power grid to supply power to the motor. The motor drives the drive wheel 111 to rotate, which in turn drives the track 112 to move, so that the vehicle body 13 moves.

[0063] Optionally, the tracked walking mechanism also includes multiple support rollers 114, which are rotatably connected to the vehicle body 13. The multiple support rollers 114 are spaced apart between the drive wheel 111 and the guide wheel 113 to bear the weight of the vehicle body 13 and distribute the pressure of the vehicle body 13 on the ground.

[0064] In other embodiments, the walking device 11 includes a motor and a tire walking mechanism. The tire walking mechanism includes at least three tires, which are spaced apart on the periphery of the bottom of the vehicle body 13. The tires are rotatably connected to the vehicle body 13. During operation, the energy storage battery 21 or the terminal 30 is connected to the power grid to supply power to the motor. The motor drives the tires to rotate synchronously so that the vehicle body 13 can move.

[0065] Optionally, the mobile crushing and screening equipment 100 also includes a hydraulic actuator, which includes a hydraulic cylinder, an energy storage battery 21 and a terminal block 30 which are electrically connected to the hydraulic cylinder, the hydraulic cylinder is rotatably connected to the vehicle body 13, and the hydraulic cylinder is rotatably connected to the crushing device 12 and the screening device. During operation, the energy storage battery 21 or the terminal block 30 is connected to the power grid to supply power to the hydraulic cylinder, and the hydraulic cylinder extends and retracts to fold the crushing device 12 or the screening device onto the vehicle body 13, thereby reducing the overall size of the mobile crushing and screening equipment 100 and facilitating transportation.

[0066] The hydraulic actuator also includes a hydraulic motor, which is connected to the crushing device and the screening device respectively. The energy storage battery 21 or terminal 30 is connected to the power grid to power the hydraulic motor. The hydraulic motor efficiently converts electrical energy into mechanical energy to provide power for the crushing operation of the crushing device 12 and the screening operation of the screening device.
