[0035] See also Figure 1-Figure 6 An ecotoxicology test device includes a mounting frame 1, an outer rotating shaft 7 and a heating device 9. The outer end of the mounting frame 1 is fixedly connected to two symmetrically arranged supporting frames 2, a drying component 6 is arranged between the two supporting frames 2, a top bracket 3 is fixedly connected to the top of the mounting frame 1, a driving component 4 is arranged at the top of the top bracket 3, and two symmetrically distributed rotating components 5 are arranged at the bottom of the top bracket 3. The drying component 6 includes a rotating drum 61, an auger blade 64 is fixedly connected to the inside of the rotating drum 61, the auger blade 64 is fixedly connected to the outer end of the outer rotating shaft 7, the outer rotating shaft 7 passes through the rotating drum 61, and the outer rotating shaft 7 is fixedly connected to the rotating drum 61.

[0036] A feed port 63 is disposed at the outer end of the rotating drum 61 , and a discharge port is disposed on a side of the rotating drum 61 away from the feed port 63 . A plurality of movable doors 62 are rotatably connected to the outer end of the rotating drum 61 .

[0037] An inner rotating shaft 8 is arranged inside the outer rotating shaft 7. The inner rotating shaft 8 is rotatably connected to the inner wall of the outer rotating shaft 7. The heating device 9 is installed inside the inner rotating shaft 8. Both ends of the inner rotating shaft 8 are fixedly connected to the two support frames 2 respectively.

[0038] Ecotoxicology experiments are used to evaluate the impact of chemicals or other pollutants on organisms in an ecosystem. Therefore, in ecotoxicology experiments, it is often necessary to analyze and study the soil. Freshly collected soil is usually humid and contains a lot of water. Therefore, it is impossible to conduct direct experimental analysis. The device in this scheme is mainly used to quickly dry the soil, thereby improving the efficiency of the experiment. A top bracket 3 is fixed on the top of the mounting frame 1. The mounting frame 1 and the top bracket 3 form an overall frame. Support frames 2 are respectively fixed on both sides of the outer ends of the support frame 2. The two support frames 2 are symmetrically arranged. The support frame 2 is mainly used to install and fix the heating device 9. A driving component 4 is installed on the top of the top bracket 3. The driving component 4 is a power source and is mainly used to drive the drying component 6 to rotate. Two rotating components 5 are arranged below the top bracket 3. The rotating component 5 is mainly used to support the drying component 6 for rotation.

[0039] The outer rotating shaft 7 in the above-mentioned is the middle area that passes through the drum 61 and the auger blade 64, and is fixedly connected to the auger blade 64 and the drum 61. By connecting the outer rotating shaft 7 with the driving component 4, the drying component 6 can be driven to rotate. An inner rotating shaft 8 is arranged inside the outer rotating shaft 7, and the inner rotating shaft 8 is rotatably connected to the outer rotating shaft 7. The two ends of the inner rotating shaft 8 are respectively fixedly connected to the two supporting frames 2. The inner rotating shaft 8 is fixed to the mounting frame 1 through the supporting frame 2, so that the outer rotating shaft 7 can drive the drying component 6 to rotate around the outer periphery of the inner rotating shaft 8. At the same time, the inner rotating shaft A heating device 9 is provided inside the shaft 8 for heating. The heating device 9 is mainly composed of a resistance wire, an insulating layer, a shell and a connecting wire. The resistance wire is the core part of the heating rod and is usually made of a high-resistivity metal such as a nickel-chromium alloy or a chromium-aluminum alloy. When current passes through the resistance wire, the resistance wire will generate heat to heat up the heating rod. The insulating layer is usually wrapped around the resistance wire to isolate the resistance wire from the external environment. The shell is usually made of metal or high-temperature resistant material to support and protect the resistance wire and the insulating layer. The connecting wire connects the heating rod to a power source to transfer current for heating.

[0040] A plurality of movable doors 62 are provided at the outer end of the drum 61. When the soil is dried in the drum 61, it is inevitable that the soil will adhere to the inner wall of the drum 61 and the auger blades 64. At this time, it is necessary to flush the inside with water to prevent the soil in samples of different experimental batches from mixing together and affecting the accuracy of the experiment. Therefore, by providing a plurality of movable doors 62, it is convenient for water to flow out when flushing the inside. At the same time, drying takes a certain amount of time. Therefore, it is necessary to install removable covers at the feed port 63 and the discharge port at both ends of the drum 61.

[0041] By placing fresh soil containing moisture into the drum 61 and then starting the drive motor 42, the drive pulley 47 is indirectly driven to drive the drum 61 to rotate. Since a heating device 9 for heating the inside of the drum 61 is installed in the inner shaft 8 inside the outer shaft 7, and the soil is driven to roll and move continuously by the auger blades 64 inside the drum 61, the soil can be dried quickly, which can shorten the preparation time of the experiment, speed up the progress of the experiment and the acquisition of results, thereby improving the efficiency and productivity of the experiment.

[0042] Optionally, in some embodiments, see Figure 1-Figure 3 The driving assembly 4 includes a fixing frame 41, the bottom end of the fixing frame 41 is fixedly mounted on the top end of the top bracket 3, the top end of the fixing frame 41 is fixedly connected to a driving motor 42, and the output end of the driving motor 42 is keyed to a driving pulley 43.

[0043] The driving assembly 4 also includes a passive pulley 44 , which is rotatably connected to the top of the fixing frame 41 , and a belt 1 45 is sleeved on the outer end of the passive pulley 44 , and the passive pulley 44 is transmission-connected to the active pulley 43 via the belt 1 45 .

[0044] The driving assembly 4 also includes a transmission pulley 47 , which is fixedly connected to the outer end of the outer rotating shaft 7 , and a second belt 46 is sleeved on the outer end of the transmission pulley 47 , and the transmission pulley 47 is transmission-connected to the driven pulley 44 via the second belt 46 .

[0045] The driving assembly 4 in this scheme is mainly used to drive the drying assembly 6. The fixing frame 41 is fixed on the top of the top bracket 3. The top of the fixing frame 41 is fixedly installed with a driving motor 42. The output end of the driving motor 42 is fixed with a driving pulley 43. The passive pulley 44 is installed on the top of the fixing frame 41 through a rotating shaft, and then connected to the driving pulley 43 through a belt 1 45. A driving pulley 47 is fixed on the outer end of the outer rotating shaft 7. The driving pulley 47 is connected to the passive pulley 44 through a belt 2 46. Therefore, when the driving motor 42 is started, the driving pulley 43 can drive the passive pulley 44 through the belt 1 45. The pulley 44 rotates, and the passive pulley 44 drives the transmission pulley 47 to rotate through the belt 2 46. At this time, the transmission pulley 47 will drive the outer shaft 7 to rotate, and the outer shaft 7 is fixedly connected to the rotating drum 61 and the auger blades 64, so it can drive the rotating drum 61 and the auger blades 64 to rotate. The soil inside the rotating drum 61 is constantly rolled and stirred by the rotation of the rotating drum 61 and the auger blades 64. It is worth mentioning that the driving motor 42 needs to rotate forward and reverse regularly to make the soil move continuously at both ends inside the rotating drum 61, and then the interior is heated by the heating device 9, which can accelerate the evaporation of soil moisture and speed up the drying time.

[0046] Optionally, in some embodiments, see Figure 4 The rotating assembly 5 includes a rotating ring 52 and two rotating wheels 51. The rotating ring 52 is fixedly installed on the outer periphery of the rotating drum 61. The two rotating wheels 51 are rotatably connected to the bottom end of the top bracket 3. An annular groove 53 adapted to the rotating wheel 51 is opened at the outer end of the rotating ring 52, and the outer end of the rotating wheel 51 abuts against the inner wall of the annular groove 53.

[0047] The rotating component 5 in this scheme is mainly used to support the drying component 6 for rotation. Two pairs of rotating wheels 51 are rotatably installed at the bottom of the top bracket 3, and two rotating rings 52 are fixed at both ends of the rotating drum 61. The rotating drum 61 can be supported by the annular groove 53 provided on the rotating ring 52 abutting against the rotating wheel 51. When the rotating drum 61 rotates, the annular groove 53 on the rotating ring 52 abuts against the rotating wheel 51, which not only supports it, but also can clamp the rotating drum 61 through the rotating wheel 51 because the annular groove 53 is concave inward, so as to prevent it from displacement, thereby improving the stability of the rotating drum 61 during rotation.

[0048] Working principle: When using the device, firstly, the soil needs to be put into the inside of the drum 61 through the feed port 63, and then the driving motor 42 and the heating device 9 are started, the active pulley 43 drives the passive pulley 44 to rotate through the belt 1 45, and the passive pulley 44 drives the transmission pulley 47 to rotate through the belt 2 46. At this time, the transmission pulley 47 will drive the outer shaft 7 to rotate, and the outer shaft 7 can drive the drum 61 and the auger blade 64 to rotate, and the soil inside the drum 61 is constantly rolled and stirred by the rotation of the drum 61 and the auger blade 64. At this time, the annular groove 53 on the rotating ring 52 abuts against the rotating wheel 51, which can not only form a support for it, but also because the annular groove 53 is concave inwardly, the drum 61 can be stuck by the rotating wheel 51 to prevent it from displacement, thereby improving the stability of the drum 61 during rotation. The inner shaft 8 inside the outer shaft 7 is equipped with a heating device 9 that can heat the inside of the drum 61, so that the soil can be dried quickly, which can shorten the preparation time for the experiment.
