Description

Technical Field

[0001] This utility model relates to the field of grain warehouse automation technology, specifically a laser radar integrated machine. Background Technology

[0002] Leveling grain in grain storage management is a crucial step in ensuring grain quality. Currently, grain leveling in my country's grain warehouses is generally done manually, which not only leads to high labor intensity and low efficiency but also faces numerous challenges such as harsh working environments and labor shortages. With rapid changes in socio-economic life, an aging population, and a decrease in the number of people willing to perform the demanding and harsh work of leveling and cleaning, a labor shortage may be imminent. To overcome the limitations of traditional manual operations, domestic and international research institutions have been dedicated to developing automated leveling robots in recent years, aiming to achieve intelligent grain leveling operations. Therefore, promoting automated grain leveling technologies has significant practical implications.

[0003] To identify the grain surface condition, laser scanning equipment is used in the grain depot to perform a high-precision point cloud scan of the grain surface in the flat warehouse without blind spots. By fusing the models, a complete 3D point cloud model of the grain warehouse and the grain surface can be obtained. The obtained model is then used to perform grain surface segmentation calculations, which can automatically calculate the grain surface height difference and the storage height. At the same time, the obtained grain surface information can also be used to guide the control of robots for leveling operations.

[0004] However, current grain storage perception mapping technology has many shortcomings, such as the inability to construct the environment of the entire grain surface; the large amount of dust inside the storage area seriously affects the mapping results, resulting in insufficient mapping efficiency and accuracy. Utility Model Content

[0005] The purpose of this invention is to solve the problems of poor dustproof effect, incomplete mapping and low efficiency in the existing technology, and to propose an integrated laser radar machine.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A lidar integrated device includes an upper housing and a lower housing. The upper housing is fixedly mounted on top of the lower housing. A first heat dissipation fin is fixed to the outer surface of the upper housing. A groove is formed on one side of both the upper and lower housings, and a first sealing ring is engaged in the groove. A fixing bracket is fixed to one side of the upper housing. A control board is provided on one side of the fixing bracket, and a communication module is fixed on the control board. A switch is provided on one side of the fixing bracket. A lidar adapter board is fixed on one side of the fixing bracket. A voltage regulator is fixed on one side of the fixing bracket. A second fixing bracket is fixed to the inner side of the lower housing. A lidar module is fixed to one side of the second fixing bracket. A camera module is fixed to one side of the second fixing bracket. A second groove is formed on one side of the lower housing, and a second sealing ring is engaged in the inner side of the groove. A second heat dissipation fin is fixed to the outer side of the lower housing.

[0008] Preferably, a slot is fixed on one side of the upper housing, a boss is fixed on one side of the slot, a fixing plate is engaged on the outer side of the slot, and a fixing hole is provided on one side of the fixing plate, with the fixing hole and the boss being positioned correspondingly.

[0009] Preferably, a mounting groove is formed on one side surface of the fixed bracket, the control board is fixedly installed in the mounting groove, and a cavity is formed on one side of the fixed bracket, the switch is fixedly installed in the cavity.

[0010] Preferably, both the lidar module and the camera module are provided in two sets, with the camera module disposed inside the second groove and the second sealing ring disposed between the camera module and the second groove.

[0011] Preferably, a mounting base is fixed to the inner side of the lower housing, and the second fixing bracket is fixedly installed on one side surface of the mounting base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The inclusion of first and second sealing rings enhances the overall sealing effect, effectively preventing dust from entering the equipment and protecting precision components such as the lidar and cameras. This extends the equipment's lifespan and reduces maintenance costs. Multiple heat dissipation fins effectively dissipate heat generated during operation, ensuring the equipment operates within a suitable temperature range, improving stability and reliability, and preventing performance degradation or damage due to overheating. Two lidar units and two camera modules scan and photograph the grain surface from different angles, providing more comprehensive data compared to traditional single-device systems. This more accurately reflects the actual condition of the grain surface, improving the precision and reliability of grain surface measurements. The communication module and switch on the main control board enable data interaction and collaborative work between multiple lidar units. Through multi-machine fusion scanning of the grain surface, a rapid and comprehensive 3D model of the grain surface can be established, significantly improving the efficiency and accuracy of grain surface monitoring in the grain depot. This provides strong support for inventory counting, grain storage status analysis, and other management tasks. A voltage stabilizer ensures stable voltage operation for all components, preventing voltage fluctuations from affecting equipment performance and improving the equipment's adaptability to the complex electrical environment of the grain depot.
