通过产生的强大的吸力,通过钢丝软管集中起来以供检验查看。 In the grain honing machine prototype system, it can often be seen that fixed or mobile honing machine racks have hoof-like probes connected with steel wire hoses, and the end is a high-pressure suction fan connected to provide high pressure. Multi-purpose double impeller 5.5kw or double impeller 7.5kw fan. The powerful suction generated by the 7.5kw grain concrete fan is collected through the steel wire hose for inspection and inspection.
Many of the fixed-type concrete prototype systems are specially designed and manufactured for the on-board grain packing and uncovered bulk grain transportation vehicles. This equipment adopts full hydraulic action, the main boom moves up and down along the Z axis, the jib expands and contracts along the X axis, the sample lever moves up and down along the Z axis, and the jib rotates in the form of gears, which can automatically sample within ± 90 °. The high-pressure blower conveying system has good performance and convenient adjustment and maintenance. It is a necessary equipment for on-board grain sampling inspection.
Principle of high pressure blower conveying grain
The main components of the entire system are:
1. Lifting range of main boom (along Z axis) 4000-5100mm
2. Telescopic range of jib (along X axis) 2900-4800mm
3. The lifting range of the sample rod (along the Z axis) 900-5000mm (
4.Rotation angle ± 90 °
5.Rotary motor 380V 0.75Kw
6.Hydraulic device 380V 4.0Kw
7.High pressure suction fan 380V 7.5Kw
8.Remote control 5 # battery-2 sections
Structural principle of fixed concrete prototype
The fixed type prototype machine is mainly composed of mechanical device, hydraulic system, electrical device and high-pressure suction fan sampler.
Principle of high pressure blower conveying grain
1. The mechanical part mainly includes the main boom lifting, the jib telescoping and the sampling rod lifting. The main arm is usually made of 300 × 300 × 5, 250 × 250 × 5 type tubes. The jib is made of 300 × 250 × 5, 250 × 150 × 5 type tubes. The metal parts are flat, and the assembly operation is smooth without blocking.
2.Hydraulic devices, the main boom lifting, the jib telescoping, and the hoisting rod lifting and lowering all adopt hydraulic devices, the structure is stable and safe. A limit position limit switch is installed at the limit point to ensure the normal and safe operation of the equipment. The hydraulic pump is directly installed in the mailbox. The power unit is installed at the bottom of the main boom, and a rain cover is installed on the power unit, which effectively ensures that the equipment operates in various environments.
3. The electric device is the hub that controls the operation of the whole machine. The electric device has an indoor control cabinet, which is convenient for operators to perform samples in different positions.
4. The sample sampler adopts the principle of negative pressure grain suction, and consists of a sample sample rod, a 7.5kw high pressure fan and a grain storage. Before inserting the sample rod into the material, be sure to turn on the fan. The grain reaches the grain storage device through the suction tube. The sample is taken out from the grain receiving bucket for analysis, thereby completing the entire sample sample operation.
