Detailed Implementation

[0018] This invention provides a vehicle-mounted yield measurement device that allows users to obtain the real-time weight of crops in the grain silo while harvesting, reducing errors from manual calculations. The device also uses satellite positioning to calculate the harvest area during harvesting, making the measurement method labor-saving and convenient.

[0019] like Figure 1 The vehicle-mounted yield measurement device shown includes a vehicle-mounted terminal, and a stress sensor, a reverse controller, a start / end button, a weighing button, a satellite positioning module, a moisture meter, and a cloud platform, all connected to the vehicle-mounted terminal. The stress sensor is connected to the vehicle-mounted terminal via a stress analysis module. The vehicle-mounted terminal indirectly obtains information about the harvester's ECU, empty bin sensor, and front and rear attitude sensors through the reverse controller, acquires the harvester's status information, and sends information to the reverse controller to control the harvester in reverse when weighing is required.

[0020] The system consists of several components. Stress sensors collect pressure signals from the grain silo and transmit them to a stress analysis module. This module amplifies and stabilizes the signal before transmitting it to the onboard terminal. The terminal then analyzes and calculates the data using data from the front and rear attitude sensors to obtain the weight data. During weighing, the onboard terminal uses a reverse controller to obtain signals from the empty silo sensor to determine the presence of grain, preventing misoperation and avoiding unnecessary weighing steps. During harvesting, the onboard terminal records location information and generates area data via a satellite positioning antenna, and collects grain moisture data using a moisture meter. Finally, all data is comprehensively analyzed and calculated to determine the yield per acre, which is displayed and stored on the onboard terminal and synchronized to a cloud platform for later retrieval and viewing by users.

[0021] like Figure 2-4 As shown, the stress sensor 1, the front and rear attitude sensors 2, and the stress analysis module 3 are mounted on the main frame. The front and rear attitude sensors 2 are fixed to the main frame with bolts, and the stress analysis module 3 is fixed to the stress analysis module bracket 31 with bolts. The stress analysis module bracket is fixed to the sheet metal of the frame by welding.

[0022] like Figure 5 As shown, the stress sensor 1 is adjusted at the angle using a conical spherical adjusting washer 12 and then bolted onto the stress sensor bracket 11. The stress sensor bracket 11 is welded onto the main frame. The stress sensor bracket is also equipped with a sensor pad 13 and a roller pad 14. The roller pad 14 is placed on the upper surface of the stress sensor 1 via the sensor pad 13 and is fixed by bolts.

[0023] like Figure 6 As shown, the empty silo sensor 4 is fixed to the bottom of the grain silo by bolts, and the main frame is equipped with a grain silo support 5.

[0024] like Figure 7 As shown, the grain silo support 5 is equipped with rollers 51, roller fixing plates 52 and 54. The rollers 51, roller fixing plates 52 and 54 are connected and installed on the grain silo support 5 by bolts and roller fixing shafts 53.

[0025] like Figure 8 and 9 As shown, the vehicle terminal 6 is bolted to the vehicle terminal bracket 61, and the vehicle terminal bracket 61 is bolted to the inner frame of the cab 7.

[0026] like Figure 10 As shown, the satellite positioning antenna 8 of the satellite positioning module is attached to the satellite positioning antenna bracket 81 with 3M double-sided adhesive, and the satellite positioning antenna bracket 81 is installed on the top of the cab with bolts.

[0027] The reverse controller is fixed to the interior of the driver's cab by bolts; In actual use, after clicking the start button, the harvesting operation can begin, and the location information will be recorded at the same time. When the grain bin is full or weighing is required, stop harvesting and click the weighing button. At this time, the on-board terminal will judge the status of the harvester and adjust its attitude (lifting the header off the ground, raising the grain discharge canister, and adjusting the chassis level). The terminal screen will display the current grain bin weight, the area worked, and the total harvested weight in real time.

[0028] When the grain bin is full or when it is necessary to measure the weight of the grain bin, click the weighing button on the terminal. The terminal will send a signal to the reverse controller to control the harvester to adjust its body posture. After the posture adjustment is completed, the terminal combines the weight data from the stress analysis module with the data from the front and rear posture sensors to calculate and display the calculated comprehensive data as the current weight of the grain bin on the screen and save the record.

[0029] If the user does not weigh the grain before unloading, the terminal will prompt the user to weigh it, and the user can choose whether to weigh it. If the weighing button is accidentally pressed when there are no crops in the grain warehouse, the system will determine it as an error and will not perform weighing. When the current field has been harvested, click the "End" button on the terminal. At this point, the terminal will integrate all operational data and satellite positioning information to generate an operational record for that field. This record includes information such as yield per acre, total harvest weight, field (operation) area, field shape, field location, and operation time. Simultaneously, this data will be synchronized to the cloud platform; users can view the information of the harvested fields through WeChat mini-programs and computers.

[0030] The technical advantage of this invention lies in improving the accuracy of weight data from multiple aspects, including structure, software, and hardware. Software optimization simplifies the use of the device, reduces the risk of misoperation, improves the system's operating efficiency, and enhances the user experience. Users can view field harvesting information via computers, mobile phones, and other devices, enabling remote monitoring and operation analysis. Through data sharing, the nation can monitor harvesting conditions in different seasons and regions across the country.

[0031] In addition to the structure described above, the present invention can replace stress sensors and attitude sensors, and the number of these sensors is not limited to one. Sensors of other shapes, accuracies, and materials can also be used as substitutes. The position of the sensors can also be adjusted according to the model. Stress sensor brackets, roller pads, sensor gaskets, grain bin brackets, roller fixing shafts, roller fixing plates, and rollers are not limited to sheet metal; they can also be made of other structural shapes such as round tubes and profiles. At the same time, stamping and welding methods can be used to improve the strength of the device. The stress analysis module, moisture module, satellite positioning antenna, and vehicle terminal are not limited to one.

[0032] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be included within the scope of protection of this utility model.
