[0002] Sandstone is a common sedimentary rock composed of quartz particles and other minerals. In the field of architecture and construction, sandstone can be crushed to make concrete, mortar, roadbed materials, etc. By crushing sandstone into particles of appropriate size, ideal materials can be obtained for building structures and foundations. Sandstone crushing requires the use of a crusher to crush sandstone. A lot of dust will be generated during the crushing process of sandstone, resulting in large dust around the sandstone crusher, thus affecting the air environment around the workstation. Utility Model Content

[0003] The utility model provides a sandstone crushing device, which solves the above-mentioned technical problems.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A sandstone crushing device comprises a machine body, a crushing roller, a support plate and a storage bin, a support column is welded at the bottom of the machine body, a crushing roller is rotatably installed inside the machine body, a discharge port is opened at the bottom end of the machine body, a storage bin is installed at the top end of the machine body, a support plate is rotatably installed inside the storage bin through a rotating seat, a weighing plate is installed on the support plate, and a weight sensor is installed between the weighing plate and the support plate, and the weight sensor is connected with the control valve signal of a hydraulic cylinder, a slot is opened through the storage bin, the hydraulic cylinder is located on the outside of the storage bin, and the output end of the hydraulic cylinder passes through the slot and is connected and fixed to the support plate, and the two ends of the hydraulic cylinder are respectively connected and fixed to the support plate and the storage bin through a rotating seat.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, rotating shafts are provided at both ends of the crushing roller, and the crushing roller is rotatably installed in the machine body through the rotating shafts, and the rotating shafts penetrate the machine body and are drivingly connected to the output end of the motor.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] As the supporting point of the crushing roller, the rotating shaft can provide a stable rotation axis to ensure the smooth operation and crushing effect of the crushing roller. Since the crushing roller is installed in the machine body through the rotating shaft, it can be relatively easy to maintain and replace. When the crushing roller needs to be replaced, it is only necessary to disassemble the rotating shaft, which simplifies the maintenance process. Through the transmission connection between the rotating shaft and the motor, the power of the motor can be effectively transmitted to the crushing roller, which improves the energy transmission efficiency and reduces the waste of energy.

[0010] Furthermore, there are two crushing rollers in total, and the two crushing rollers are connected to the motor through gear meshing transmission or respectively.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The two crushing rollers work at the same time, which can improve the processing capacity and crushing efficiency of the crushed materials. The gears between the crushing rollers are meshed or connected to the motor separately, so that they can work together to crush the materials more efficiently. Since there are two crushing rollers crushing at the same time, the materials can be crushed more evenly, avoiding excessive concentration of a single crushing point, reducing the local wear of the materials, and improving the uniformity of the products. The two crushing rollers are driven by gear meshing or connected to the motor separately, which can maintain a relatively stable working state, reduce vibration and impact, and reduce the noise and failure rate of the machine. According to needs, different crushing effects and material particle size adjustments can be achieved by adjusting the gear transmission ratio or independently controlling the motor speed, which improves the adaptability and flexibility of the equipment.

[0013] Furthermore, the width of the support plate is half of the inner diameter of the storage bin, and the support plates are symmetrically distributed inside the storage bin.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] Setting the pallets to be symmetrically distributed can make the materials receive uniform force, avoiding the deviation of materials in the storage bin. In addition, the weighing plate and weight sensor can realize automatic metering of materials, improving the accuracy and efficiency of metering. Through the control valve signal connection of the hydraulic cylinder, automatic switch control can be realized, reducing the intervention of manual operation, reducing the difficulty and labor intensity of manual operation. Due to the realization of automatic metering and control, manual operation is reduced, production efficiency and production capacity are improved, and the accuracy and stability of production are also improved. The weight sensor can realize real-time monitoring and data collection of material weight and flow, which is convenient for subsequent data statistical analysis and quality control.

[0016] Furthermore, when the weight sensor between the weighing plate and the pallet detects that the weight of the raw materials piled above the weighing plate reaches the set value, the weight sensor controls the control valve of the hydraulic cylinder to activate the hydraulic cylinder to drive the pallet to flip open. When the raw materials above the pallet enter the machine body, the pallet is pushed closed by the hydraulic cylinder to prevent dust generated by crushing in the machine body from overflowing.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] Through the monitoring and control of the weight sensor, the entire operation process is automated, without the need for human intervention, reducing errors and uncertainties in human operation. The flipping, opening and closing action of the pallet can ensure that the material enters the machine body smoothly from the top of the pallet, and effectively prevents the dust generated during the crushing process from overflowing, ensuring the sealing and environmental hygiene inside the machine body. The automatic flipping and closing design makes the process of materials entering and leaving the machine body smoother and more efficient, improves production efficiency, and reduces production time and costs. And by preventing dust from overflowing, the spread and pollution of dust are reduced, and the cleanliness of the working environment and the health and safety of employees are improved. Effectively controlling the overflow of dust helps reduce wear and corrosion on equipment, extends the service life of equipment, and reduces the cost of maintenance and replacement of parts.

[0019] The beneficial effects of the utility model are:

[0020] The pallet in the storage bin is controlled by the hydraulic cylinder to automatically flip and close without manual intervention. The weight sensor is connected to the control valve signal of the hydraulic cylinder, and when the set value is reached, the hydraulic cylinder is automatically triggered to ensure the accurate flipping and closing of the pallet.

[0021] The equipment adopts the design of storage bin and pallet, which makes the overall structure compact and occupies less space, suitable for use in limited sites. The width of the pallet is half of the inner diameter of the storage bin. Through symmetrical distribution, the space of the storage bin is effectively utilized, and the loading efficiency is improved.

[0022] The crushing roller adopts a double-roller structure. The two crushing rollers are connected to the motor through gear meshing transmission or separately, and they cooperate with each other to crush the materials. The double-roller structure increases the crushing area, can crush sandstone more fully, and improves the crushing efficiency.

[0023] The weight sensor controls the action of the hydraulic cylinder to ensure that the pallet is turned over and closed at the right time, preventing dust from spilling during crushing and ensuring operational safety. The pallet is pushed and closed by the hydraulic cylinder, effectively preventing dust from spilling during crushing and reducing pollution to the surrounding environment.
