Description

Technical Field

[0001] The invention relates to the technical field of loading equipment, and in particular to a 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

[0007] The present invention aims to provide a quantitative loading system in view of the problem that the prior art cannot realize reliable and accurate metering loading.

[0008] The technical solution of the present invention is: a quantitative loading system, including a feeding device, a quantitative bin, a weighing sensor and a weighing controller, the feeding device is installed at the bin mouth at the bottom of the bin, the quantitative bin is arranged at the lower part of the feeding device, the quantitative bin and the foundation are connected through the weighing sensor, the weight of the quantitative bin is measured by the weighing sensor, the weighing sensor is electrically connected to the weighing controller, the feeding device includes a feeding gate, the feeding gate controls the feeding into the quantitative bin, and the lower end of the quantitative bin is provided with a discharge gate, and the discharge gate can discharge the material in the quantitative bin when it is opened.

[0009] The feeding device is provided with a distributor, and the quantitative bin is arranged below the distributor. The quantitative bin comprises a first quantitative bin and a second quantitative bin which are independently arranged. The first quantitative bin and the second quantitative bin are connected to the base through weighing sensors respectively. The weighing sensors measure the weight of the first quantitative bin and the second quantitative bin respectively. The distributor can feed the first quantitative bin and the second quantitative bin respectively. The two quantitative bins load and unload quantitatively in a cycle in turn, and the efficiency is high.

[0010] The material distributor comprises a first material distributor chute and a second material distributor chute. The first material distributor chute is provided with a first feeding gate, and the second material distributor chute is provided with a second feeding gate. The first material distributor gate and the second material distributor gate can respectively control feeding into the first quantitative bin and the second quantitative bin.

[0011] It also includes a quantitative bin moving mechanism, which includes a mobile bracket and a driving device, which are connected to the mobile bracket. The quantitative bin includes a first quantitative bin and a second quantitative bin which are independently arranged. The first quantitative bin and the second quantitative bin are respectively arranged on the mobile bracket through weighing sensors. The driving device can drive the mobile bracket and the first quantitative bin and the second quantitative bin installed on the mobile bracket to move. The use of the quantitative bin moving mechanism can reduce the height of the feeding device, increase the volume of the quantitative bin, and reduce the requirements for the installation space.

[0012] The quantitative bin moving mechanism also includes a guide track coupled to the moving bracket, and the moving bracket moves along the guide track.

[0013] The driving device includes a hydraulic cylinder driving device, a pneumatic cylinder driving device, an electric cylinder driving device, a winch driving device, a gear rack driving device or a screw driving device.

[0014] A first discharge gate is provided at the lower part of the first quantitative bin, and a second discharge gate is provided at the lower part of the second quantitative bin. The first discharge gate is arranged close to the second quantitative bin, and the second discharge gate is arranged close to the first quantitative bin, so as to realize concentrated discharge.

[0015] In order to prevent the dust generated when the feeding device feeds the quantitative bin from spreading outward, a sealing member is provided between the feeding device and the quantitative bin, and the sealing member is a flexible sealing member or a mutually coupled sealing assembly.

[0016] The flexible sealing element comprises rubber, polyurethane, canvas, felt or brush.

[0017] The mutually coupled sealing components include mutually coupled bosses and grooves or airtight sealing curtains.

[0018] The airtight sealing curtain comprises an annular air groove and an injection assembly. The annular air groove is arranged at the lower part of the feeding device, and the injection assembly is arranged in the annular air groove. A sealing plate is arranged at the upper part of the quantitative bin opposite to the opening of the annular air groove. A ventilation gap is left between the side wall of the annular air groove and the sealing plate. The ventilation gap is 5mm to 50mm, and the preferred ventilation gap is 10mm to 30mm. The gas ejected by the injection assembly overflows outward from the ventilation gap, and a pressure difference is formed inside and outside the annular air groove. The high air pressure in the annular air groove prevents the dust in the quantitative bin from diffusing outward.

[0019] It also includes a dust suppression device, which is arranged at the lower part of the feeding device and / or at the lower part of the quantitative bin discharge gate to suppress dust generated when the feeding device feeds the quantitative bin or when the quantitative bin discharges the material.

[0023] The first quantitative bin and the second quantitative bin which are independently arranged are quantitatively weighed and loaded in a cycle, so the continuity is good and the loading efficiency is high.

[0024] The double quantitative bin structure with the quantitative bin moving mechanism reduces the height of the feeding device, increases the volume of the quantitative bin, and reduces the requirement for installation space.
