Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a scanning mechanism of a sampling machine. Background Art

[0002] The sampling machine is a device used to sample grain in a grain depot. It usually includes a frame, a connecting seat, a boom and a sampling rod. The frame generally includes a number of vertically arranged support beams and a crossbeam arranged transversely and fixed to the top of each support beam. The sliding seat cooperates with the rack on the crossbeam through a gear and can slide on the crossbeam under the action of a drive motor. The sampling rod is connected to the boom, which is hinged to the sliding seat and drives the sampling rod upward or downward under the drive of another drive motor to achieve sampling.

[0003] However, in actual work, especially when sampling grain trucks, according to national standards, sampling needs to be carried out within a certain area in the truck bed, and the sampling points are also different for grain trucks of different sizes. Therefore, in order to ensure that the sampling meets the national standards, different parking reminder lines are generally set on the ground by spraying or painting in the prior art. Before sampling, grain trucks of different sizes are parked at the parking reminder lines that meet the requirements, so as to ensure that the sampling range in the truck bed is determined.

[0004] However, this method is also somewhat irrational. Specifically, when the grain truck is parking, the driver has a blind spot and cannot park in place at the corresponding parking prompt line in one go. The parking position needs to be repeatedly adjusted, which makes the operation very inconvenient. Summary of the invention

[0005] The utility model aims at solving the above problems in the prior art and proposes a scanning mechanism of a sampling machine. The technical problem to be solved by the utility model is: how to quickly determine the sampling area.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a scanning mechanism of a sampling machine, the sampling machine includes a sampling arm, one end of the sampling arm is connected to a vertically arranged sampling rod, and is characterized in that the scanning mechanism includes a scanner, the scanner has two, the two scanners are fixed to one end of the sampling arm connected to the sampling rod, the two scanners are radially arranged along the sampling rod, and the center lines of the two scanners are perpendicular to each other.

[0007] Compared with the prior art, the scanning mechanism of the sampling machine has the advantage that before sampling the grain truck, the driver parks the vehicle at a designated location, which is usually one side of the sampling machine. At this time, the scanner on the sampling boom is running. It is worth mentioning that the scanner disclosed in this case is a prior art, such as a wide-angle laser scanner or a wide-angle infrared scanner in the prior art. The two scanners are arranged along the radial direction of the sampling rod, so that the detection end of each scanner is arranged downward. Since the center lines of the two are arranged vertically, one of the scanners can measure the length of the grain truck bucket. One scanner performs a quick scan, while the other scans the width of the grain truck bed. At the same time, the two scanners transmit the detected data back to the terminal computer through wired or wireless transmission. The terminal computer calculates and reasonably plans the sampling area based on the current national standard. Finally, the sampling boom controls the lifting of the sampling rod to complete the sampling work. Through the above methods, the driver does not need to repeatedly adjust the parking position. The scanner can quickly measure the size of the truck bed and quickly determine the sampling area on the premise of ensuring that the sampling meets the standards, which is conducive to the efficient sampling work.

[0008] In the scanning mechanism of the above-mentioned sampling machine, the scanning mechanism also includes a mounting plate that is L-shaped and connected to the sampling boom, one end of the mounting plate is a fixed section, and the other end is a mounting section. The two scanners are respectively located on both sides of the mounting section, one of the scanners is screwed to the outer wall of the mounting section by bolts, and the other scanner is screwed to the sampling boom by fasteners and presses the fixed section onto the sampling boom. Specifically, the installation of the two scanners is achieved by relying on the mounting plate, and the two scanners are respectively assembled on the fixed section and the mounting section of the mounting plate by cooperating with bolts. While ensuring that the center lines between the two scanners are perpendicular, the fasteners that fix one of the scanners to the fixed end can be connected to the sampling boom, so that the mounting plate is also directly clamped on the side wall of the sampling boom while ensuring that the scanner is installed, ensuring that the assembly is more labor-saving.

[0009] In the scanning mechanism of the above-mentioned sampling machine, the sampling boom includes a long strip-shaped main body and a U-shaped connecting frame, the connecting frame is vertically arranged and the middle part is hinged to one end of the main body through a hinge shaft, and the fixed section is pressed against the side wall of the connecting frame by one of the scanners. Through the arrangement of the connecting frame, it is ensured that the sampling rod has sufficient adjustment freedom and that the sampling rod can always be oriented vertically downward. At the same time, the two scanners are positioned on the side wall of the connecting frame through the fixed section of the mounting frame and arranged along the radial direction of the sampling rod, that is, the orientation of the two scanners can be quickly corrected by the orientation of the sampling rod, ensuring the rapid measurement of the length and width of the truck bucket.

[0010] In the scanning mechanism of the above-mentioned sampling machine, the mounting section is folded up to form a connecting portion, and the scanning mechanism also includes an outer cover, which is screwed to the connecting portion through a fastener and covers the top and circumference of each scanner. Through this arrangement, the top and circumference of each scanner are fully covered to prevent it from being directly exposed to the outside, reduce the influence of external factors on its work, and ensure sufficient protection for each scanner.

[0011] In the scanning mechanism of the above-mentioned sampling machine, a clearance hole is opened at the lower end of the connecting frame, and the sampling rod is inserted into the clearance hole and is clamped with the inner wall of the clearance hole, so as to ensure that the sampling rod is easy to install and firmly connected.

[0012] Compared with the existing technology, the scanning mechanism of this sampling machine has the following advantages:

[0013] The scanning mechanism of the sampling machine is achieved by installing two scanners radially arranged along the sampling machine on the sampling boom, and the center lines of the two scanners are arranged vertically. Before the sampling work is carried out, the driver stops the vehicle and measures the length of the truck bed with one of the scanners and the width of the truck bed with the other scanner. The summarized data is then transmitted back to the terminal computer and the size of the truck bed is calculated, thereby scientifically and rationally determining the sampling area.
