Introduction:
The crushing bucket is usually installed on the excavator and uses the hydraulic power of the excavator. It is widely used in the crushing of various ores and bulk materials in mining and smelting, building materials, highways, railways, water conservancy and chemical industries.
The working principle:
The crushing method of the crushing bucket is a curved extrusion type. The hydraulic motor drives the eccentric spindle through the spline shaft, and the movable jaw moves up and down through the eccentric shaft. When the movable jaw rises, the angle between the top plate and the movable jaw becomes larger, and the feeding port The wedge-shaped space becomes larger, and the bulk material moves downward under the action of gravity. When the movable jaw plate approaches the fixed flange, the wedge-shaped space of the feeding port becomes smaller, and the material is squeezed, rubbed, and milled. At the same time, when the movable jaw goes down, the angle between the top plate and the movable jaw becomes smaller, and the movable jaw leaves the fixed jaw plate under the action of the pull rod and the spring. At this time, the crushed material is discharged from the lower opening of the crushing cavity. With the continuous rotation of the hydraulic motor, the jaws of the crushing bucket are periodically crushed and discharged.
The crushing bucket is driven by hydraulic pressure, and the motor is driven by high-pressure oil provided by the hydraulic excavator. The motor drives the eccentric spindle through the spline shaft, and the eccentric spindle drives the movable flange to crush the materials. The hydraulic control part adopts the motor function valve and the speed control valve. The motor function valve and the speed control valve are installed together through the hydraulic manifold. The function of the motor function valve: control the oil pressure entering the hydraulic motor within the required range, and balance the input pressure. The pressure of oil and return oil prevents the formation of cavities in the hydraulic motor and damages the hydraulic motor. The function of the speed control valve is to generate back pressure on the oil return circuit, and to control the speed of the hydraulic motor to keep stable when the load changes greatly.
Structural features：
The crushing bucket can crush the stones twice, and adjust the crushing and discharging size according to the required specifications. The high mobility has the characteristics of convenient movement. The hydraulic system of the excavator is used, and it does not need electricity, which is also convenient for construction in mountainous areas. Let's take a look at the structural characteristics of the excavator crushing bucket:
(1) It is directly driven by a hydraulic motor, no belt is needed, the transmission efficiency is higher, and the maintenance is simpler.
(2) The upper and lower jaw plates can be used interchangeably, and the front and rear of a single front plate can also be used interchangeably, which greatly prolongs the service life of the product.
(3) The crushing bucket is made of high-strength wear-resistant plates imported from Sweden as a whole, with high structural strength and low product weight.
(4) The core components hydraulic motor and eccentric shaft mechanism are imported with original packaging, and the quality is stable and reliable.
(5) The size of the discharge port can be easily adjusted from 15-120 mm.
Usage:
It can quickly crush quarry stones, prefabricated slabs and concrete steel beams, quickly separate concrete and steel bars, save time and effort, and save the utilization of resources and wastes. Recycled crushing bucket jaw crushing bucket corresponding to concrete and stone recycling of various excavator models (20-50 tons) can reduce the transportation of concrete blocks on the construction site and the transportation of crushed stones and other engineering costs. In addition, the product can also reduce traffic congestion caused by vehicle transportation, traffic accidents, reduce urban noise, road maintenance costs, and reduce carbon dioxide emissions, etc., and promote the direct recycling of concrete waste on site.
Tips:
The operation of the crushing bucket is simple, and the crushing work can be achieved only by controlling the excavator and the foot pedal, but often the operator may not wait for the crushing work before the crushing bucket is in normal operation. The correct way is to leave no load for 2-3 minutes before use, and confirm whether the machine is running normally before the crushing operation can be carried out normally.
The above is the introduction of the crushing bucket. Its performance is stable and its work efficiency is high.If you want to know more about the crusher bucket, please contact us sales@bucketmaster.com.cn!
