Description

Technical Field

[0001] The utility model relates to the technical field of food sample pressing detection, in particular to a labor-saving food sample pressing device. Background Art

[0002] According to the relevant technical requirements of the "Gamma Energy Spectrum Analysis Method for Radionuclides in Environmental and Biological Samples" (GB / T 16145-2022), the collected samples must be processed by physical methods to make samples with the same or similar geometry and density as the standard source. In this process, the dry sample needs to be placed in a 2L Marin cup. The traditional method requires staff to press the steel plate by hand to slowly compact the sample. Due to limited human strength, it is impossible to make the density of the sample to be tested close to that of the standard source. This traditional method is not only time-consuming and labor-intensive, but also fails to press the sample to be tested evenly, and may also lead to inaccurate measurements. The labor-saving food sample pressing device applied for this time uses the principle of leverage to compact the sample while saving effort, thereby improving the accuracy and stability of the measurement.

The lower end of the driving assembly 104 is detachably connected to a pressing plate 106. The pressing plate 106 is provided in a variety of sizes. When in use, first put the food into the Marin cup, and then place the Marin cup on the support table 100, with the cup mouth of the Marin cup facing the pressing plate 106, and then flip the handle 105 downward. The handle 105 transmits torque to the driving assembly 104, and the driving assembly 104 drives the pressing plate 106 to move downward, and the pressing plate 106 presses and compacts the food in the Marin cup.

[0025] In one embodiment, the driving assembly 104 includes a driving block 200, a sliding rod 201, a driving gear 202, a connecting bearing 203, and a limit plate 204. One end of the support plate 103 is fixedly connected to the driving block 200. A sliding slot hole is passed through the driving block 200, and the sliding rod 201 is slidably connected in the sliding slot hole. The upper end of the sliding rod 201 is fixedly connected to the limit plate 204 after passing through the sliding slot hole. The lower end of the sliding rod 201 is fixedly connected to the clamping plate 106 by a bolt. The connection between the driving block 200 and the support plate 103 is fixedly connected with two groups of connecting bearings 203 respectively. The driving block 200 and the support plate 103 between the connecting bearings 203 are rotatably connected. There is a driving gear 202, and the rotating shaft of the driving gear 202 is fixedly connected in the connecting bearing 203. One end of the rotating shaft of the driving gear 202 passes through the connecting bearing 203 and is fixedly connected to the handle 105. A plurality of tooth grooves 205 are provided on the sliding rod 201 on one side of the driving gear 202. The driving gear 202 is meshed and connected with the tooth grooves 205 on one side of the sliding rod 201. When in use, the handle 105 is flipped downward, and the handle 105 drives the driving gear 202 to rotate. The driving gear 202 drives the sliding rod 201 to move downward through the tooth grooves 205, and the sliding rod 201 drives the pressing plate 106 to move, thereby realizing the pressing operation of the pressing plate 106 on the food.

When the sliding rod 201 moves downward, the spring 302 is stretched. After the food is compacted, the handle 105 is flipped upward. At this time, the spring 302 applies an upward pulling force to the sliding rod 201, thereby facilitating the sliding rod 201 to return to its initial position upward. At the same time, when there is no operation, the sliding rod 300 is prevented from moving downward under the action of gravity.

[0028] In one embodiment, in order to meet the requirements of pressing samples of Marin cups of different sizes, two sizes of pressing plates are designed, and the diameters of the two pressing plates are 160 mm and 120 mm respectively.

[0029] The working principle of the present invention is as follows: First, the appropriate compression plate 106 is selected according to the size of the Marlin cup. The Marlin cup containing the food sample is placed on the support 100. The handle 105 is pulled downward. The compression plate 106 moves downward under the action of the lever principle, evenly compacting the food sample. This ensures that the density of the sample to be tested is close to or consistent with that of the standard sample, thereby improving the accuracy and reliability of the results of radionuclide gamma spectrum analysis.
