Problems solved by technology
At present, there are two conventional layouts of truck scales: above-ground and underground. When the truck scale adopts the conventional above-ground layout, the ramps on both sides have a large slope, which causes safety hazards when some agricultural transport vehicles (such as tractors) pass through, and the straw is easy to pass. Scattering; when the conventional underground layout is adopted, the drainage point of the foundation pit of the truck scale is relatively deep, and it is difficult to discharge the accumulated water, and it is difficult to clean up the straw and sundries falling in the foundation pit
[0003] Combining the above unfavorable factors, the following common problems have appeared in the straw transportation and weighing process of the current biomass power plant: 1. The over-limit straw loaded by agricultural transport vehicles is easy to collide with the weighbridge room and the access control system; 2. When the above-ground layout is adopted, due to the steep slopes on both sides of the truck scale, the agricultural transport vehicles loaded beyond the limit cannot safely pass through the truck scale metering system in the factory area, and the straw is easy to fall; 3. When the underground layout is adopted, straw and debris It is difficult to clean up the objects falling in the foundation pit of the truck scale, and the debris entering the inside of the scale will easily affect the measurement accuracy of the truck scale. The drainage point of the underground foundation pit is deep, and the accumulated water is difficult to discharge

Embodiment Construction
[0011] The design method of the straw weighing semi-underground truck scale in the biomass power plant of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0012] The implementation of the semi-underground truck scale design method for straw weighing in the biomass power plant of the present invention is shown in the accompanying drawings
[0013] The design method of the present invention is: arrange the box-shaped foundation of the truck scale 2 in the foundation pit, the top surface of the box-shaped foundation is 200mm higher than the ground, and the upper surface of the scale body of the truck scale 2 is at the same level as the top surface of the box-shaped foundation; The front and rear ends of the truck scale 2 in the forward direction of the vehicle are provided with ramps 3, the ramp 3 is connected to the box foundation, and the slope of the ramp 3 is less than or equal to 4%. In the conventional ground la...

The invention relates to a design method of a straw transportation weighing semi-underground truck scale in a biomass power plant. The method comprises the following steps: a box-shaped base of the truck scale is arranged in a ground pit, a top surface of the box-shaped base is 200 mm higher than the ground, and a scale body upper surface of the truck scale and the top surface of the box-shaped base are on a same horizontal plane; front and back ends of the truck scale along a forward direction of a vehicle is provided with a ramp with a gradient less than or equal to 4%, a distance between atruck scale house and a gate control system and the truck scale is larger than or equal to the scale body width of the truck scale, box-shaped base inner walls at left and right sides of the truck scale are symmetrically provided with manholes, and an inner bottom of the box-shaped base is provided with a scupper. The design method has the following advantages: 1. a pass requirement of an agricultural transport vehicle with overrun loading of straw in the biomass power plant is satisfied, and collision between the overloading straw and the truck scale house and the gate control system is avoided; 2. scattered straw and foreign materials which fall into the ground pit of the truck scale are easy to clean; 3. drainage of the ground pit of the truck scale is smooth.
Description
technical field [0001] The invention relates to a design method of a semi-underground truck scale for straw transportation and weighing in a biomass power plant, which belongs to the category of measuring equipment. Background technique [0002] With the continuous construction of biomass power generation projects, some problems have been exposed in straw transportation in biomass power plants. For example, there are many agricultural vehicles in straw transportation, and the vehicle conditions are uneven; some transportation vehicles are loaded with super high and super wide transportation; straw transportation Strict binding measures were not taken. At present, there are two conventional layouts of truck scales: above-ground and underground. When the truck scale adopts the conventional above-ground layout, the ramps on both sides have a large slope, which causes safety hazards when some agricultural transport vehicles (such as tractors) pass through, and the straw is easy ...
