[0002] Soil composition testing is an important project in environmental monitoring. The collected soil samples need to go through the steps of drying, grinding, sieving, mixing and bottling in order to prepare for various tests. In the prior art, before grinding the soil samples, it is usually necessary to manually dry the soil samples by airing or baking them, and then collect the dried soil samples and put them into the grinding equipment for grinding. The automation level is low and it takes a lot of time.

[0003] To this end, in the related art, a Chinese patent with publication number CN217819587U proposes a soil sample processing device for environmental testing. After placing the soil sample in the grinding disc, the drying time is set by the electronic control unit. The electric heating wire heats the grinding disc according to the set time to dry the soil sample. After the specified time is reached, the lifting rod rises so that the grinding unit contacts the bottom surface of the grinding disc. Then the motor drives the grinding unit to grind the soil sample in the grinding disc. After the grinding is completed, the lifting rod is lowered, and the staff can remove the grinding disc to collect the ground soil sample. The processing device can automatically dry and grind the soil sample, with a high degree of automation, reducing the time cost of soil sample processing.

[0004] However, in this soil sample processing device for environmental testing, the drying and grinding of the soil sample need to be performed separately and individually, which still prolongs the processing time of the soil sample to a certain extent. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0020] The present application embodiment discloses a soil sample processing device for environmental management. Figure 1 The soil sample processing device for environmental treatment includes a processing box 10, a heating base 20, a support table 40 and a vibration assembly 30. The processing box 10 is fixed above the heating base 20, and the crushed soil sample in the processing box 10 is dried by heat exchange between the bottom of the processing box 10 and the heating base 20. The vibration assembly 30 is installed above the support table 40, and the vibration assembly 30 moves through the outer wall of the processing box 10, so that it is used to cooperate with the processing box 10 to crush the placed soil sample.

[0021] See also Figure 2 The processing box 10 may include a box body 11, a central axis 12, a pressing plate 13, a sieve plate 14, two springs 15, a placement area 16 and a collection area 17. The pressing plate 13 and the sieve plate 14 are both slidably arranged in the inner cavity of the box body 11, and the opposite sides of the pressing plate 13 and the sieve plate 14 are connected to the top inner wall and the bottom inner wall of the box body 11 by a spring 15, so that when the pressing plate 13 and the sieve plate 14 are close to each other, the spring 15 can be stretched to deform, and the soil sample can be squeezed to break it; when the pressing plate 13 and the sieve plate 14 move in opposite directions, the spring 15 can be reset, and during the reset process of the spring 15, the pressing plate 13 and the sieve plate 14 produce multiple shaking actions. The central axis 12 passes through the center of the pressing plate 13 and the sieve plate 14, and the two ends are fixedly connected to the top inner wall and the bottom inner wall of the box body 11 respectively. Two springs 15 are sleeved on the outside of the central axis 12, so that the central axis 12 limits and guides the deformation of the spring 15 and the movement of the pressing plate 13 and the sieve plate 14. A plurality of evenly distributed circular holes are formed on the sieve plate 14 and penetrate the sieve plate 14, so that the soil particles after extrusion and crushing can pass through the circular holes and fall to the inner bottom of the box body 11 for drying; a plurality of evenly distributed conical protrusions are formed on the lower surface of the pressing plate 13, so that the soil sample can be better crushed during the extrusion process and the soil sample can be reduced from adhering to the bottom of the pressing plate 13. The placement area 16 and the collection area 17 are both formed on the outer wall of the box body 11, and the placement area 16 is located between the pressing plate 13 and the sieve plate 14, and the collection area 17 is located between the sieve plate 14 and the bottom inner wall of the box body 11, so that the user can put in or take out the soil sample from the placement area 16 and the collection area 17 respectively. The placement area 16 and the collection area 17 are both hinged with a cover plate that can block the placement area 16 or the collection area 17. During the sample processing process, the cover plate can be used to cover the placement area 16 and the collection area 17 to prevent soil particles from being thrown out of the processing box 10. The bottom of the box body 11 is set as a heat-conducting metal plate, and the bottom of the box body 11 is in contact with the top of the support table 40. The support table 40 is installed with an electric heating wire inside, and the top of the support table 40 is set as a heat-conducting metal plate, so that the two groups can conduct the heat generated when the electric heating wire is activated, and dry the soil particles contained in the bottom of the box body, and the aforementioned crushing and drying process of the soil sample can be carried out simultaneously. The side of the box body 11 facing the vibration component 30 is also formed with a positioning groove 18 that cooperates with the vibration component 30.

[0022] See also Figure 3The vibration assembly 30 includes a hydraulic cylinder 31, a pusher 32, two sets of parallel connecting rods 33, two movable parts 34 and two pressing parts 35. The hydraulic cylinder 31 is mounted and fixed on the top of the support platform 40, and the output end of the hydraulic cylinder 31 is fixedly connected to the middle of the pusher 32, so that it can drive the pusher 32 to move toward or away from the box body 11. The top and bottom of the pusher 32 are rotatably connected to the two sets of parallel connecting rods 33 respectively, and each set of parallel connecting rods 33 is rotatably connected to a movable part 34 on one side away from the pusher 32. The pressing part 35 is formed on the side of the movable part 34 facing the processing box 10, and the pressing part 35 moves through the positioning groove 18. The parallel connecting rod 33 includes at least two connecting rods, and one end of the at least two connecting rods close to the pushing body 32 is rotatably connected to the pushing body 32, and one end close to the movable part 34 is rotatably connected to the movable part 34. The at least two connecting rods are parallel to each other, so that the deflection of the parallel connecting rod 33 can drive the movable part 34 and the pressing part 35 to move in translation under the limiting guide of the positioning groove 18. The two pressing parts 35 are respectively located above the pressing plate 13 and below the sieve plate 14, so that when the pushing body 32 moves away from the box body 11, the deflection of the parallel connecting rod 33 can be used to drive the two pressing parts 35 to move toward each other, so that the pressing plate 13 and the sieve plate 14 are pushed close to and squeeze the soil sample; when the pushing body 32 moves close to the box body 11, the deflection of the parallel connecting rod 33 can be used to drive the two pressing parts 35 to move away from each other, so that the pressing plate 13 and the sieve plate 14 move away from each other under the reset deformation of the spring 15, and generate shaking during the reset process of the spring 15.

[0023] In this embodiment, the width of the positioning groove 18 is equal to the width of the two pressing parts 35, so that the positioning groove 18 can limit the movement of the two pressing parts 35 along the width direction of the positioning groove 18, and the two pressing parts 35 can only move along the height direction of the positioning groove 18.

[0024] The system of the present invention may further include a control system for controlling the operation of the hydraulic cylinder and the electric heating wire to automatically crush and dry the soil sample. It should be understood that the control system has no particular limitation and can be implemented by the control technology under the prior art, which will not be described in detail here.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
