Abstract
Description
Technical Field
[0001] The invention relates to the technical field of loading equipment, and in particular to a double-bin mobile quantitative loading system. Background Art
[0002] The existing process of loading bulk materials from silos is that the vehicle drives under the silo, and the operator controls the gate or feeder to load the vehicle. There are three main control methods for loading accuracy.
[0003] The first is to control the gate or feeder to load the vehicle based on the loading experience of the loaders. This method requires high experience and operational proficiency of the loaders, and has low loading accuracy. It often causes overloading or underloading beyond the allowed range of the vehicle, resulting in range loading or unloading, low loading efficiency, poor on-site environment, and high labor intensity.
[0004] The feeder installed at the bottom of the second silo has a continuous dynamic metering function, and dynamic metering loading is performed through the feeder. Although this metering loading method has achieved a certain metering loading effect, the conveying section of the dynamic metering weighing feeder is short and is greatly affected by the silo pressure and the tension of the conveyor belt. It has poor stability and accuracy, requires frequent calibration, and has poor actual use effect.
[0005] The third method is to install a truck scale at the vehicle loading point at the bottom of the silo, and use the truck scale to measure and control the truck loading amount. This method of using the truck scale to measure and control loading is costly, and the truck scale is located at the bottom of the car, which requires a relatively large foundation pit. When loading, some spilled materials enter the foundation space at the bottom of the truck scale and are difficult to clean. It is common for materials to get stuck between the truck scale and the foundation, causing large errors in the truck scale weighing, or water enters the foundation pit, causing damage to the truck scale.
[0006] The above-mentioned loading methods cannot meet the requirements of the existing loading system for automation and intelligence. Summary of the invention

[0009] The loading section guide rail and the unloading section guide rail are independently arranged or connected by a movable connection mechanism that enables the loading section guide rail and the unloading section guide rail to move in the up and down directions, so as to avoid interference with weighing.
[0010] The unloading section guide rail is provided with a weighing sensor, and the weighing sensor detects the load weight on the unloading section guide rail.
[0011] The first quantitative bin and the second quantitative bin are independently arranged or connected by a movable connection mechanism that allows the first quantitative bin and the second quantitative bin to move in the up and down directions, thereby avoiding mutual interference during weighing.
[0012] The movable connection mechanism includes a soft connection mechanism, a connecting rod connection mechanism, an elastic connection mechanism or a snap connection mechanism.
[0013] The moving support member includes a rolling support member or a sliding support member.
[0014] The feeding device comprises a feeding gate, and the feeding gate controls the loading into the first quantitative bin or the second quantitative bin.
[0015] The lower part of the first quantitative bin and the lower part of the second quantitative bin are both provided with discharge gates, and the discharge gates can unload the materials in the first quantitative bin or the second quantitative bin.
[0016] The discharge gate at the lower part of the first quantitative bin is arranged close to the second quantitative bin, and the discharge gate at the lower part of the second quantitative bin is arranged close to the first quantitative bin, so as to realize the centralized discharge.

Preferably, the joint width L between the loading section guide rail and the unloading section guide rail is 0.5mm~2mm, avoiding interference with weighing.
[0029] Alternatively, the loading section guide rail 4.1 and the unloading section guide rail 4.2 may be connected by a movable connection mechanism 10 that enables the loading section guide rail 4.1 and the unloading section guide rail 4.2 to move in the up and down directions, thereby avoiding interference with weighing.
[0030] The first quantitative bin 2 and the second quantitative bin 3 are connected by a movable connection mechanism 10 that enables the first quantitative bin 2 and the second quantitative bin 3 to move in the up and down directions to avoid mutual interference during weighing.
[0031] The movable connection mechanism 10 comprises a soft connection mechanism 10.1, a connecting rod connection mechanism 10.2, an elastic connection mechanism 10.3 or a snap connection mechanism 10.4.
[0032] The soft connection mechanism 10.1 comprises a rope connection 10.11 or a chain connection 10.12, and both ends of the rope or chain are respectively connected to two connected members.
[0033] The connecting rod connection mechanism 10.2 comprises a connecting rod 10.21, and both ends of the connecting rod 10.21 are movably connected to two connected members respectively.

[0036] The moving support member 9 is a rolling support member 9.1, and may also be a sliding support member.
[0037] The feeding device 1 comprises a feeding gate 1.1, which controls the loading into the first quantitative bin 2 or the second quantitative bin 3.
[0038] The lower part of the first quantitative bin 2 and the lower part of the second quantitative bin 3 are both provided with a discharge gate 11, and the discharge gate 11 can unload the materials in the first quantitative bin 2 or the second quantitative bin 3.
