The weighing leather is provided with a weighing sensor. The rough weighing belt mainly has the function of conveying materials to the fine weighing belt, the quantity of the materials is roughly calculated in the conveying process, and the weighing process is dynamic. Weighing of precision belts requires static weighing for accuracy. When the rough-weighing belt conveys materials, the fine-weighing belt performs proportional reciprocating motion to enable the materials to be evenly spread on the belt, when the materials conveyed by the rough-weighing belt approach the amount required by a plan, the materials are stopped from being conveyed, the fine-weighing belt also stops moving, and at the moment, the material number on the fine-weighing belt can be accurately measured.

Example six:
the present embodiment is a method for loading bulk materials into a site by using the loading system of the above embodiment, and the method includes the following steps (see fig. 6 in the flowchart):
the upper computer is a general management device such as a sales server of a goods yard and the like which is specially used for production sales management, and is usually a sales server or a workstation of the goods yard. The sales management servers acquire the quantity or variety information of the loaded materials through communication with users, and send the information to the dispatching command device. The variety of the goods refers to the properties of the materials, such as sand with different sizes of particles, stones with various grades, coal with different sizes of particles and the like. A general goods yard can stack a plurality of kinds of materials in different areas, and in the process of selling, the goods of a plurality of kinds of different particles need to be mixed together and sold as a kind of goods designated by a user, so that the processes of accurately weighing and mixing the materials of the plurality of kinds need to be carried out. For example: coal with three kinds of particles, namely large, medium and small, is stored in a goods yard, and is required to be mixed according to the proportion of 1: 2: 3, and a loading plan is formulated according to the requirement of a client and the quantity and tonnage of loaded vehicles, so that the loading process is optimized. Therefore, it is important to acquire the number and variety of loaded goods.
the method comprises the steps that firstly, the stacking field state sensors scan the existing material pairs in the field, due to the fact that the stacking field state sensors are arranged, scanning can be conducted from different positions, the accurate positions and the shapes of all material piles in the stacking field (goods field) can be obtained, the quantity of materials can be accurately calculated according to the shapes of the material piles, meanwhile, the calculated quantity of all the material piles is verified according to the records of goods arrival and goods delivery of the material field, meanwhile, the goods of which particles are in all the material piles are obtained, and the goods serve as the basis for starting a new round of material loading process. If there is a loading operation in the current cargo yard, it is also necessary to predict the loading operation being performed, and subtract a predetermined amount.
In this embodiment, the "new round of loading process" may be that there is no loading operation in the goods yard at the beginning, or may be that other loading operations are being performed in the goods yard, where the "new round of loading process" refers to a loading operation performed on an item requested by a certain user among a plurality of loading processes.
And 3, analyzing the state of the loading machine: obtaining the accurate position of each loading machine at the initial loading according to the accumulation field state sensor and the running track of each loading machine;
the individual loading machines are moved during the loading process, so that when starting a new loading process again, the current position of the individual loading machine should be known. There are many ways to obtain the current position of these loading machines, such as satellite positioning, historical recording, or on-site monitoring and analysis, i.e. analysis by means of the records of the yard status sensors located on site. Since there may be a plurality of loading machines and loading vehicles operating at the loading site, the operating and stopping positions of various vehicles and machines in the cross-over work may affect other equipment operating simultaneously, and thus traffic safety is very important. In order to ensure the driving safety of the goods yard, the combination of satellite positioning, historical recording, field monitoring and other modes can be adopted to monitor the position change of various devices in the goods yard in real time, so as to ensure that various vehicles do not conflict.
And 4, analyzing the state of the loaded vehicle: obtaining the accurate position of each loading vehicle at the initial loading according to the accumulation field state sensor and the running track of each loading vehicle;
since the loading vehicles are foreign vehicles, the routes of the vehicles must be strictly defined in the cargo area, and even so, the positions and the routes of the loading vehicles must be closely monitored, so that when a new round of loading process is started, the positions and the routes of the loading vehicles in the current cargo area must be checked to avoid collision.
since there may be multiple loading tasks in progress in the yard, there are multiple loading machines and loading vehicles running in the yard, and how to avoid collisions of individual vehicles and to complete each loading job in order requires precise scheduling. For example, if only one material is needed for one loading function, only one material taking weighing loader and one platform wagon sweeper can be dispatched, but if the material of various particles is needed, several material taking weighing loaders and one material preparing machine, one platform wagon sweeper and the like which are matched with each other can be needed.
And step 6, executing loading operation: the command scheduling device commands the loading machine and the loading vehicle to execute loading operation according to the loading plan until the loading is finished; the loading process comprises the following steps: get material weighing loader and go to required material heap and acquire the material and weigh the back output to following the complex proportioning machine, during the material output to the loading vehicle of following of proportioning machine after mixing, the loading vehicle is gone to the position of setting for and is carried out the flatcar by the flatcar scavenging machine, wipe the angle and clean.
In the process of loading, the dispatching and commanding device sends operation instructions to corresponding loading machines through a wireless communication network, each loading machine is commanded to operate in place, and meanwhile, a loading vehicle is commanded to operate in a matching manner through a communication or text or image display system, and the process needs careful planning and accurate execution to avoid errors or accidents.
7. The method according to claim 6, wherein said loading of step 6 comprises the sub-steps of:
this substep is main obtains the material of appropriate quantity, the material that will pass through the accurate weighing, for this embodiment has adopted the mode of two steps to walk, and first step is carried while weighing through thick title material, and the accurate belt then back-and-forth movement, and the material is even to be spread out on the belt as far as, this is because, under the condition that highly receives the restriction, it is unrealistic to set up higher surge bin, consequently uses the even material of spreading out of belt feeder then can obtain accurate weighing effect through a plurality of weighing sensor that set up under the belt.
the mixing process starts when the first material enters the roller, and the materials are uniformly mixed in the rolling process because the helical blades in the roller can roll the materials continuously.
The scraper plate reciprocates for several times to scrape materials, the roller with the soft hair rotates, and the scattered materials on the four edges of the carriage are swept into the carriage. The floating process is as follows: the materials at the four corners of the carriage are stirred by utilizing the rotary trowelling device, so that the materials reach the top ends of the four corners, and the function of corner plastering is achieved.
Finally, it should be noted that the above is only for illustrating the technical solution of the present invention and not for limiting, although the present invention is described in detail with reference to the preferred arrangement, it should be understood by those of ordinary skill in the art that the technical solution of the present invention (such as the form of the loading device, various control processes, the sequence of steps, etc.) can be modified or equivalently replaced without departing from the spirit and scope of the technical solution of the present invention.
