Description

Technical Field

[0001] The invention relates to the technical field of sampling and detection, in particular to an electric portable beet juice sampling device. Background Art

[0002] The sugar content of sugar beets is an important indicator for measuring the quality of sugar beets. The determination of the sugar content of sugar beet tubers is an important task for raw material staff of sugar companies. Every year during the sugar beet harvest season, a large number of sugar beet root samples need to be determined at different raw material bases to provide important reference data for sugar companies' sugar beet production and the rational planting of sugar beets in the coming year. At the same time, sugar beet researchers also need to determine the sugar content of a large number of sugar beet tubers during the sugar beet harvest season every year to provide data support for scientific research work such as the screening of new sugar beet varieties, the rational application of fertilizers, the effective prevention and control of pests and diseases, and other sugar beet planting management.

[0003] When conventionally measuring the sugar content of beetroots, a sampler is first inserted into the beetroot to separate a sample from the beetroot, and then the juice is squeezed. After the beet juice is squeezed out, it is dripped onto a pliometer for sugar content measurement.

[0004] Chinese patent publication number: CN212059425U discloses a beetroot sampling and juice pressing device, which includes a sampling tube with openings at both ends; a juice pressing rod is movably inserted into one end of the sampling tube, a raw juice outlet is opened on the side wall of the sampling tube adjacent to the other end, and a sample blocking plate is vertically inserted into the sampling tube between the other end of the sampling tube and the raw juice outlet.

[0005] Although the above-mentioned prior art has the function of automatically squeezing juice after sampling, its sampling end is open. When used, it is inserted into the beetroot to separate a whole piece for squeezing juice. Therefore, the sampling will sample the epidermis at the same time. The epidermis of the beetroot contains components different from the interior, including but not limited to fiber, pigment, wax, etc. These components may be mixed into the juice during the squeezing process, affecting the direct determination of the sugar content. Moreover, the epidermis may also be contaminated by microorganisms. These microorganisms may produce metabolites during the squeezing process, further interfering with the determination results of the sugar content. Impurities on the epidermis, such as soil, sand, residual pesticides, etc., if not effectively removed, will also be mixed into the juice. These impurities may not only affect the accuracy of the sugar content determination, but also may have adverse effects on subsequent processing and use. In addition, the existing sampling device squeezes the juice of a whole piece of sample when sampling. Squeezing the juice of the whole piece is not only laborious, but also has a small surface area, which is not conducive to the juice being fully squeezed out, and the juice yield is poor.

[0006] Therefore, it is necessary to propose an electric portable beet juice sampling device to solve the above problems. Summary of the invention

At this time, the adjusting shaft 26 is driven to rotate in the opposite direction, and then the adjusting shaft 26 drives the sampling blade 10 to reset and hide in the first through groove 29. Then, as the driving rod 13 continues to be pushed, the second driving block 36 enters the second straight groove 33, and the sampling blade 10 remains stationary. The upper end of the traction groove 34 on the guide column 14 will contact the limit block 35, and then the guide column 14 pushes the connecting rod 23 downward through the traction groove 34, and the connecting rod 23 pushes the extrusion block 25 downward, and the extrusion block 25 pushes the cut sample to the extrusion groove 46 for squeezing juice, and the juice enters the collecting tank 45 for storage through the leakage hole 47.Then remove the positioning frame 6, pull the lower end of the sampling inner cylinder 4 out of the beet root, then remove the sampling cone 5, and remove the cone 48 from the transition part 44, drip the juice onto the plummeter for sugar content determination, and clean the squeeze groove 46;,

[0058] Finally, when resetting, the driving source 12 is controlled to retract, the driving rod 13 and the sampling inner cylinder 4 are reset, and when the locking groove 28 reaches the second through groove 37, one end of the locking tongue 38 will automatically insert into the locking groove 28 for locking due to the reset of the second spring 43, and the extrusion block 25 will be driven by the guide column 14 through the traction groove 34 to reset to the second convex ring 24. The sampling cone 5 can be installed for subsequent use. The device is electrically controlled, and a reciprocating stroke of the driving source 12 can realize the steps of piercing, rotating slicing, and squeezing juice in one step. It is convenient and quick to use, and the efficiency is improved.
