[0025] EMBODIMENT

[0026] REFERENCE Figures 1-4 For the embodiment of the present application, the embodiment provides a multi-point sampling device for environmental detection, comprising,

[0027] The material taking assembly 100 comprises a fixed plate 101, a material guide cover 102 rotatably installed in the middle of the fixed plate 101, a main shaft 103 movably inserted in the center of the material guide cover 102, and a spiral drill bit 104 fixedly connected to the end of the main shaft 103, wherein the spiral drill bit 104 is rotatably connected to the inner side of the end of the material guide cover 102.

[0028] The storage assembly 200 comprises a discharging pipe 201 sealingly installed on the side wall of the end of the material guide cover 102, a connecting seat 202 fixedly installed on the lower end of the discharging pipe 201, a storage barrel 203 movably inserted on the lower end side wall of the connecting seat 202, and a sieve plate 204 rotatably installed on the middle side wall of the connecting seat 202, wherein the sieve plate 204 is sealingly inserted on the upper end of the storage barrel 203, and the side wall of the sieve plate 204 is provided with a sieve hole structure matched with the storage barrel 203.

[0029] The fixed plate 101 is a basic fixed component of the material taking assembly, the material guide cover 102 is used for guiding the collected sample material to smoothly enter the subsequent material storage assembly, and can also protect the internal material taking structure to a certain extent, the main shaft 103 rotates under the driving of the driving component, and then drives the spiral drill bit 104 to rotate, realizing the collection of the environmental sample, the function of the discharging pipe 201 is to stably and leaklessly convey the sample material collected in the material guide cover 102 to the connecting seat 202 and the material storage barrel 203 below, ensuring the integrity and purity of the sample material in the transmission process. Through the rotation of the sieve plate 204 and the screening effect of the sieve hole, impurities and large particle substances in the sample material can be separated, and only the sample material meeting the requirements can enter the material storage barrel 203, ensuring the purity of the sample.

[0030] Specifically, the material storage assembly 200 further comprises an adjusting motor 205 fixedly installed on the side wall of the connecting seat 202, and the output end of the adjusting motor 205 is fixedly connected to the center of the sieve plate 204.

[0031] The adjusting motor 205 can drive the sieve plate 204 to rotate, and the sieve plate 204 can be flexibly adjusted to an appropriate sieve hole position to adapt to the screening requirements of different environmental samples.

[0032] Further, the material storage assembly 200 further comprises a vibration motor 206 fixedly connected to the side wall of the connecting seat 202, and the vibration motor 206 is installed outside the sieve plate 204.

[0033] When the vibration motor 206 works, high-frequency vibration is generated to prevent the sample material from being blocked at the sieve hole, improve the screening efficiency, and ensure that the sample material can smoothly pass through the sieve plate 204 and enter the material storage barrel 203.

[0034] Further, the material taking assembly 100 further comprises a driving motor 105 fixedly connected to the end portion of the main shaft 103, and a limiting plate 106 fixedly connected to the side wall of the end portion of the driving motor 105, and the side wall of the limiting plate 106 is provided with a hand slot structure.

[0035] The driving motor 105 drives the main shaft 103 and the spiral drill bit 104 to rotate at high speed to complete the collection of the environmental sample, and the limiting plate 106 facilitates the hand operation of the operator. At the same time, the limiting plate 106 can also protect the driving motor 105 to a certain extent, preventing the motor from being damaged due to collision or other reasons during operation.

[0036] Preferably, the material taking assembly 100 further comprises a spring 107 sleeved in the middle of the main shaft 103, and the spring 107 is in elastic contact with the end portion side wall of the material guide cover 102 and the limiting plate 106 respectively.

[0037] The spring 107 can play a buffering role in the sampling process, and when the auger bit 104 encounters a large resistance, the spring 107 can absorb part of the impact force through compression deformation, protect the internal structure of the device from being damaged, and also make the sampling process more stable.

[0038] It should be pointed out that the material taking assembly 100 further comprises a guide rod 108 fixedly connected to the side wall of the end portion of the guide cover 102, and the end portion of the guide rod 108 is inserted into the middle of the through hole in the side wall of the limiting plate 106.

[0039] The cooperation of the guide rod 108 and the limiting plate 106 provides a guiding effect for the movement of the driving motor 105, the main shaft 103 and other components, ensures that these components can move in the predetermined direction, avoids deviation or shaking, and guarantees the accuracy of the sampling work.

[0040] Preferably, the material taking assembly 100 further comprises an anchor rod 109 threadedly connected to the side wall of the fixed plate 101, and the end portion of the anchor rod 109 is in a pointed structure.

[0041] The anchor rod 109 is screwed into the ground or other fixed plane, further enhancing the fixing stability of the fixed plate 101, preventing displacement of the device during sampling, and affecting the sampling effect.

[0042] In use, when environmental detection sampling is performed, the operator first stably fixes the device at the sampling position through the anchor rod 109 on the fixed plate 101. Then, the driving motor 105 is started, the driving motor 105 drives the main shaft 103 to rotate, and then the auger bit 104 starts to rotate. The auger bit 104 cuts and excavates the sample material in the environment during rotation, and pushes it along the spiral blade into the guide cover 102. If the auger bit 104 encounters a large resistance during sampling, the spring 107 will be compressed and deformed, playing a buffering role and protecting the internal structure of the device. At the same time, the guide rod 108 and the limiting plate 106 cooperate with each other to ensure the stable movement direction of the main shaft 103 and related components under the action of the spring 107. The operator can adjust and operate the device through the hand position recess structure on the limiting plate 106, to ensure the smooth progress of the sampling work.

[0043] The collected sample material enters the connecting seat 202 from the guide cover 102 through the discharging pipe 201. At this time, the adjusting motor 205 drives the sieve plate 204 to rotate, and the sample material is screened on the sieve plate 204. The sample material meeting the size requirements of the sieve hole falls into the storage barrel 203 through the sieve hole, while the impurities and large particles remain on the sieve plate 204. At the same time, the vibration motor 206 works, and the vibration generated is transmitted to the sieve plate 204, preventing the sample material from being blocked at the sieve hole and improving the screening efficiency. When the sample material in the storage barrel 203 reaches a certain amount, it can be taken off from the connecting seat 202, and a new storage barrel 203 is replaced to continue the sampling work.

[0044] In summary, the spiral drill bit 104 rotates at high speed under the drive of the driving motor 105, which can quickly and effectively cut and excavate the environmental sample material, greatly improving the sampling efficiency and meeting the requirements of high efficiency of multi-point sampling for environmental detection. The buffering effect of the spring 107 and the guiding effect of the guide rod 108 and the limiting plate 106 enable the device to maintain a stable working state even when encountering a large resistance during sampling, avoiding equipment damage or sampling deviation caused by excessive resistance, and ensuring the stability and accuracy of the sampling work. The hand slot structure on the limiting plate 106 facilitates the operator to hold and operate the device, and the design of the anchor rod 109 enables the device to be quickly and stably fixed at the sampling position before sampling, improving the convenience of operation.

[0045] By adjusting the rotation of the sieve plate 204 by the adjusting motor 205, the screening efficiency and accuracy can be flexibly adjusted according to the characteristics of different environmental samples, ensuring that only the sample material meeting the requirements enters the storage barrel 203, improving the purity of the sample, and providing a reliable data basis for subsequent environmental detection and analysis. The vibration generated by the vibration motor 206 can effectively prevent the sample material from being blocked at the sieve hole, ensuring the continuity and efficiency of the screening work, avoiding sampling interruption and sample loss caused by blockage. The design of the storage barrel 203 being movably inserted into the lower end side wall of the connecting seat 202 enables the storage barrel to be conveniently and quickly replaced after being filled with sample material, improving the overall efficiency of the sampling work.
