Description

Technical Field

[0001] The utility model relates to the technical field of grain sampling, in particular to a deep-layer grain sampling device. Background Art

[0002] Sampling is an important process to ensure fair grain trade, storage, processing and production, and is of great significance to ensuring grain quality.

[0003] At present, grain sampling machines require manual labor to insert the sampling tube into the grain, which has low work efficiency. At the same time, the sampling tube usually needs to be lengthened, which is inconvenient to carry.

[0004] For example, a deep grain sampling device for a grain vertical silo disclosed in Chinese patent CN216746902U can store tubes that need to be lengthened in the sampling tube by using a sampling main unit, a hose, a sampling tube, a fixing mechanism, and a fixing frame. At the same time, the fixing mechanism can save a certain amount of manpower and improve work efficiency when sampling. A second gear is installed at the output end of the third motor, and the second motor drives the second gear to rotate. The rotation of the second gear drives the first gear to rotate, thereby driving the spiral column to rotate downward. The spiral blades will enable the spiral column to enter the deep layer of the grain faster, and then the sampling tube is inserted from the center of the spiral column into the granary. The sampling tube can be inserted into the deep layer of the grain with less manpower, which greatly saves manpower.

[0005] However, the device cannot adjust the distance between the first support plate and the second support plate during use, resulting in the inability to sample granaries of different sizes, and its use is limited.

[0006] For this reason, we urgently need to provide a kind of grain deep sampling device. Utility Model Content

When the telescopic member is extended or retracted, the bobbin can be driven to be inserted into or pulled out of the grain.

The upper end of the movable plate is provided with an internal thread, and the movable plate is threadedly connected to the outer surface of the connecting rod. By rotating the connecting rod and the left and right movable plates, the two movable plates are moved in opposite directions, thereby adjusting the distance between the left and right brackets, and sampling of granaries of different sizes can be achieved.

[0014] Preferably, a limiting groove having the same width as the movable plate is provided on the upper surface of the connecting plate, and the limiting groove serves to limit the movement of the movable plate, so that the movable plate moves linearly along the limiting groove.

[0028] The adjusting unit is arranged on the left side of the sampling main body 1 , and the clamping unit is arranged on the left side of the sampling main body 1 .

[0029] The adjusting unit includes a connecting plate 601, a telescopic member 602, a connecting block 603, a connecting rod 604 and a movable plate 605. The connecting plate 601 is arranged on the left side of the sampling host 1. A limiting groove equal to the width of the movable plate 605 is provided on the upper surface of the connecting plate 601. The limiting groove limits the movement of the movable plate 605 so that the movable plate 605 moves linearly along the limiting groove.
