Description

Technical Field

[0001] The utility model relates to the technical field of soil mercury detection, in particular to an automatic material spreading device for batch mercury detection of soil samples. Background Art

[0002] The determination of mercury content in soil samples is often achieved through a mercury analyzer. Existing mercury analyzers support batch testing of multiple groups of samples, which can meet the comparison or statistical tests of multiple control groups. The sample boat that comes with the equipment is usually used as a carrier for the sample. A certain amount of weighed sample must be spread flat on the bottom of the sample boat before subsequent measurement tests can be carried out. In order to ensure that the sample paving meets the test requirements, it is usually completed manually and then placed in the corresponding slot of the mercury analyzer. During this process, the sample boat with the paving needs to be transferred. Bumps are inevitable during the process, which can easily lead to rework of the paving, thereby affecting the efficiency of batch mercury measurement. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides an automatic spreading device for batch mercury measurement of soil samples, which can automatically spread materials relative to a mercury meter and meet the spreading requirements of the measurement, thereby improving the test efficiency of batch mercury measurement.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides an automatic spreading device for batch mercury measurement of soil samples, including a spreading mechanism, which moves close to a carrier, and the carrier is rotatably arranged to align the sample boat thereon with the spreading mechanism; a plurality of the sample boats are arranged around the carrier shaft, and the sample boat grooves are radially arranged along the shaft, and the spreading end of the spreading mechanism is slidably matched with the sample containing groove of the sample boat; a weighing module is provided at the spreading end of the spreading mechanism.

[0005] Furthermore, the material spreading mechanism is provided with a sample container, the discharge end of the sample container is connected to the weighing container of the weighing module through a regulating valve, a pressure sensing module is provided at the bottom of the weighing container, and the signal output end of the pressure sensing module is electrically connected to the regulating valve through a control module.

[0006] Furthermore, the weighing container is flipped and arranged at the bottom side of the discharge end of the sample container.

[0007] Furthermore, the end surface of the weighing container is tilted, and the upper edge of the end surface is turned over to approach the sample boat.

[0008] Furthermore, the port width of the weighing container is adapted to the sample containing groove width of the sample boat.

[0009] Furthermore, the port of the weighing container is arranged to be raised or lowered relative to the bottom of the sample containing tank.

[0010] Furthermore, a vibration module is correspondingly arranged on the bottom surface of the sample boat.

[0011] Beneficial effect: The utility model is an automatic spreading device for batch mercury measurement of soil samples. Based on the original rotating platform of the mercury analyzer, a spreading mechanism adapted thereto is newly added.

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Attached Figure 1 The utility model is a schematic structural diagram of an embodiment. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] As attached Figure 1 The automatic spreading device for batch mercury measurement of soil samples comprises a spreading mechanism 1, wherein the spreading mechanism 1 moves close to a carrier 2, and the carrier 2 is rotatably arranged to align a sample boat 3 thereon with the spreading mechanism 1; a plurality of the sample boats 3 are arranged around the rotating shaft of the carrier 2, and the grooves of the sample boats 3 are radially arranged along the rotating shaft, and the spreading end of the spreading mechanism 1 is slidably matched with the sample receiving groove of the sample boat 3; a weighing module 4 is arranged at the spreading end of the spreading mechanism 1.

[0015] This solution can be applied to batch automatic mercury analyzers. The original rotating platform of the mercury analyzer is used as a carrier, and a new spreading mechanism is added to directly spread the multiple sample boats on the carrier in sequence. Through the sliding cooperation between the spreading end and the sample boat sample tank, an appropriate amount of sample is spread flat on the bottom of the sample tank to avoid the impact of sample accumulation on the mercury measurement test. The weighing module can select the appropriate sample weighing amount according to the sample concentration, so as to meet the spreading requirements of batch mercury measurement, and there is no need to transfer the sample boat after spreading. After the spreading is completed, the test phase can be directly entered, which can avoid sample loss or damage caused by accidental collision during the transfer process. There is no need to re-spread the sample to supplement the control group blank, which can effectively improve the test efficiency of batch mercury measurement.

[0016] The material spreading mechanism 1 is provided with a sample container 11, the discharge end of the sample container 11 is connected to the weighing container 41 of the weighing module 4 through a regulating valve 12, a pressure sensing module 42 is provided at the bottom of the weighing container 41, and the signal output end of the pressure sensing module 42 is electrically connected to the regulating valve 12 through a control module.

[0017] There may be multiple sample containers, and corresponding weighing containers. If multiple control group tests are conducted on the same sample in the same batch, a single sample container and a weighing container can be used to complete the laying. If multiple samples are tested at the same time, different soil samples are loaded in different sample containers, and the weighing containers are used in a corresponding manner to avoid cross contamination between different samples, thereby avoiding affecting the test results.

[0018] The weighing container needs to be set as a straight cylindrical structure so that the weight of the sample falling into it acts on the pressure sensor at the bottom, thereby ensuring the accuracy of the weighing amount.

[0019] Preferably, the weighing container 41 is flipped and arranged at the bottom side of the discharge end of the sample container 11. The port surface of the weighing container 41 is tilted, and the upper edge of the weighing container 41 is flipped and close to the sample boat 3. The port width of the weighing container 41 is adapted to the sample slot width of the sample boat 3.

[0020] Embodiment: The weighing container can be a square-mouthed sample tube with a single-end opening. After a certain amount of sample is weighed in the tube, the tube body is flipped so that its port faces the groove surface at one end of the sample containing groove. The tube body port can be first flipped so that it fits with the groove end surface. At this time, the tube body is inclined, and the sample in the tube is gathered at the port. Then the tube body is driven to slide along the groove and flipped at the same time so that the tube body port faces downward. As the tube body slides relative to the sample containing groove, a sample layer with a relatively uniform thickness is formed on the bottom surface of the groove, and almost no accumulation is formed.

[0021] Preferably, the port of the weighing container 41 is arranged to be raised and lowered relative to the bottom of the sample container 41. The discharge amount of the weighing container during the movement can be adjusted by the lifting and lowering adjustment, thereby controlling the thickness of the sample layer formed by flattening.

[0022] Preferably, a vibration module 5 is correspondingly arranged on the bottom surface of the sample boat 3. After the material is laid, the flatness of the sample layer can be further improved by slightly and evenly vibrating the bottom surface of the sample boat without additional manual leveling, which is beneficial to improving the overall efficiency of the test.

[0023] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
