Description

Technical Field

[0001] This utility model relates to a soil drying box, and more particularly to a soil drying box with intelligent temperature control function applied in the field of drying equipment. Background Technology

[0002] Soil drying is an indispensable pretreatment step in soil analysis, environmental monitoring, and agricultural research. In soil sample processing in laboratories and research institutions, soil drying, as a key pretreatment step, plays a crucial role in the accuracy of subsequent experimental analysis results due to its efficiency and quality.

[0003] Chinese patent CN212902360U discloses a soil drying device, including a drying box. A control box is bolted to one outer wall of the drying box, and rollers are bolted to both outer walls of the drying box. Ventilation windows are provided on both outer walls of the drying box. A rectangular opening is provided on the top outer wall of the drying box, and a cover plate is movably connected to the inner wall of the rectangular opening. A discharge port is provided on the outer wall of the drying box away from the control box. The drying box is driven to shake by the cooperation of an electric telescopic rod and a spring rod, which facilitates the uniform drying of the soil inside the drying box. The discharge of the drying box is easily adjusted by a crank arm, which solves the problem of inconvenient discharge in existing drying equipment.

[0004] In terms of drying efficiency, the heating and ventilation systems of traditional equipment have obvious defects. The heating elements are usually poorly arranged, resulting in uneven temperature distribution in the drying chamber and local overheating or undercooling areas. Soil samples are heated unevenly in these areas, the drying time is prolonged, and the overall efficiency is low. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that, in terms of drying efficiency, the heating and ventilation system design of traditional equipment has obvious defects. The heating elements are usually not arranged reasonably, resulting in uneven temperature distribution in the drying chamber, with local overheating or undercooling areas. Soil samples are heated unevenly in these areas, the drying time is prolonged, and the overall efficiency is low.

[0006] To address the aforementioned problems, this utility model provides a soil drying box with intelligent temperature control, comprising a drying device body, multiple individual drying compartments at the front end of the drying device body, sealed cabinet doors hinged to the front ends of the individual drying compartments, drying air outlets fixedly connected to the rear inner walls of the individual drying compartments, dust-absorbing perforated strips on the upper side of the rear inner walls of the individual drying compartments, soil storage cups placed on the lower inner walls of the individual drying compartments, an electric push rod fixedly connected to the upper inner walls of the individual drying compartments, an inner vertical rod fixedly connected to the output end of the electric push rod, multiple spring connectors fixedly connected to the outer end of the inner vertical rod, the multiple spring connectors being arranged in a ring at equal intervals, an outer claw bar fixedly connected to the end of the spring connectors away from the inner vertical rod, the outer claw bar being rotatably connected to the output end of the electric push rod, a horizontal plate fixedly connected to the rear inner walls of the individual drying compartments, a vibrator fixedly connected to the end of the horizontal plate near the electric push rod, and an annular locking outer plate fixedly connected to the output end of the vibrator.

[0007] In the aforementioned soil drying chamber with intelligent temperature control, this solution involves filling the soil sample to be dried into a soil storage cup and placing it on the storage base groove in a separate drying compartment. During drying, an electric push rod drives the inner vertical rod to move a special forked, roughened-surface outer claw bar up and down in the soil sample, breaking down the aggregated structure and increasing the contact area between the soil and hot air to help improve drying efficiency.

[0008] As a further improvement of this application, a suction pump is connected to the outside of the dust-absorbing perforated strip, and the dust-absorbing perforated strip is located directly above the drying air outlet.

[0009] As a further improvement of this application, a silicone inner scraper blade is fixedly connected to the inner side wall of the annular locking outer plate, and an electric push rod passes through the inner and outer holes of the annular locking outer plate.

[0010] As a further improvement of this application, the lower inner wall of the drying compartment is provided with a storage base groove, and a contact sensor is fixedly connected to the lower inner wall of the storage base groove.

[0011] As another improvement of this application, the inner end of the storage base groove is provided with an anti-slip and stable base plate, which is located directly above the contact sensor.

[0012] As a further improvement to this application, the inner end of the soil container is filled with several sample soils, and the right end of the drying device body is fixedly connected to a smart controller panel.

[0013] As a further improvement to this application, the smart controller panel is electrically connected to the suction pump, vibrator, and contact sensor via wires and an electric push rod.

[0014] In summary, this method involves filling the soil sample to be dried into a soil storage cup and placing it on the base plate groove within a separate drying compartment. The non-slip, stable base plate ensures stable placement. After the sealed cabinet door is closed, a contact sensor detects the sample and sends a signal to the smart controller panel. The controller then activates the corresponding compartment's drying air outlet according to a preset program to deliver hot air and begin drying. During drying, an electric push rod drives the inner vertical rod, which in turn moves a specially forked, roughened-surface outer claw bar up and down within the soil sample, breaking down the aggregated structure and increasing the contact area between the soil and the hot air to improve drying efficiency. Once drying is complete, the electric push rod... As the rod retracts and the external claw bar passes through the annular engagement hole in the outer plate, the silicone scraper blades clean up any residue. Simultaneously, the vibrator starts to shake off the residue, and dust is drawn in by the dust-absorbing perforated strip to keep the compartment clean. This equipment has an intelligent temperature control function. For example, the intelligent controller panel can activate only the drying air outlet of the sample compartment based on the contact sensor signal to achieve intelligent and energy-saving operation. The drying compartment is independently designed and can process multiple samples simultaneously and intelligently control the working status of each compartment. The overall operation is simple, energy-efficient, and highly intelligent, making it suitable for soil sample processing in laboratories, research institutions, and other places.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figure 1-6 This invention illustrates a soil drying box with intelligent temperature control, comprising a drying device body 1, multiple individual drying compartments 2 at the front end of the drying device body 1, sealed cabinet doors 3 hinged to the front ends of the individual drying compartments 2, drying air outlets 5 fixedly connected to the rear inner wall of the individual drying compartments 2, dust-absorbing perforated strips 4 provided on the upper side of the rear inner wall of the individual drying compartments 2, soil storage cups 14 placed on the lower inner wall of the individual drying compartments 2, and an electric push rod 10 fixedly connected to the upper inner wall of the individual drying compartments 2. The output end of the electric push rod 10... An inner vertical rod 11 is fixedly connected. Multiple spring connectors 12 are fixedly connected to the outer end of the inner vertical rod 11. The multiple spring connectors 12 are arranged in a ring at equal intervals. An outer claw bar 13 is fixedly connected to the end of the spring connector 12 away from the inner vertical rod 11. The outer claw bar 13 is rotatably connected to the output end of the electric push rod 10. A horizontal plate 6 is fixedly connected to the rear inner wall of the drying compartment 2. A vibrator 7 is fixedly connected to the end of the horizontal plate 6 near the electric push rod 10. An annular locking outer plate 8 is fixedly connected to the output end of the vibrator 7.

[0027] Figure 1-6 The suction strip 4 is shown to be connected to a suction pump. The suction strip 4 is located directly above the drying air outlet 5. The inner wall of the annular locking outer plate 8 is fixedly connected to a silicone inner scraper blade 9. The electric push rod 10 passes through the hole in the annular locking outer plate 8. The inner end of the soil cup 14 is filled with several sample soils. The right end of the drying device body 1 is fixedly connected to a smart controller panel 18.

[0028] Figure 1-6The method involves filling the soil sample to be dried into the soil container 14 and placing it on the bottom plate groove 15 within the drying compartment 2. The anti-slip and stable bottom plate 16 ensures the soil container 14 remains stable during the drying process. After the sealed cabinet door 3 is closed, the contact sensor 17 senses the placement of the soil container 14 and sends a signal to the intelligent control panel 18. The intelligent control panel 18 then activates the corresponding drying air outlet 5 in the drying compartment 2 according to a preset program, supplying hot air into the compartment and initiating the drying operation. During the drying process, the electric push rod 10 drives the inner vertical rod 11 downwards, causing multiple external claw bars 13 to unfold and extend into the soil container 14. The external claw bars 13 push up and down within the soil sample. These external claw bars 13 have a special forked structure and their surfaces are roughened to increase friction with the soil. Driven by the electric push rod 10, the external claw bars 13 reciprocate up and down within the soil sample. This movement effectively breaks down the soil sample. The aggregated structure inside the soil sample makes the soil particles looser, thus significantly increasing the contact area between the soil and hot air, accelerating the heat exchange process between the hot air and the soil, and greatly improving the drying efficiency. After drying, the electric push rod 10 retracts, driving the external claw bar 13 out of the soil container 14. During the retraction process, the external claw bar 13 passes through the central hole of the annular locking outer plate 8, and the silicone inner scraper blade 9 scrapes the external claw bar 13 to clean the residual dry soil layer. At the same time as the electric push rod 10 retracts, the vibrator 7 starts, generating vibration force to further shake off the dry soil layer on the external claw bar 13. The shaken-off dust is sucked out by the dust-absorbing perforated strip 4 to ensure the cleanliness of the drying compartment 2. The combined use of the external claw bar 13 and the vibrator 7 further improves the drying efficiency and cleaning effect, ensuring the drying quality of the soil sample. The overall equipment has the advantages of simple operation, energy efficiency, high intelligence, and is suitable for soil sample processing in laboratories, research institutions and other places.

[0029] Second implementation method:

[0030] Figure 1 , Figure 3 , Figure 7This invention discloses a soil drying chamber with intelligent temperature control. The lower inner wall of the drying compartment 2 is provided with a storage base groove 15, and a contact sensor 17 is fixedly connected to the lower inner wall of the storage base groove 15. An anti-slip and stable base plate 16 is provided at the inner end of the storage base groove 15, located directly above the contact sensor 17. The intelligent controller panel 18 is electrically connected to the suction pump, vibrator 7, and contact sensor 17 via wires and an electric push rod 10. When only some drying compartments 2 need to be activated, the intelligent controller panel 18, based on the signal from the contact sensor 17, only activates the corresponding drying air outlet 5, while other compartments remain closed, thus achieving intelligent and energy-saving operation of the equipment. This solution, through reasonable structural design and intelligent control system, achieves efficient drying and cleaning of soil samples. The independent design of the drying compartments 2 allows the equipment to process multiple samples simultaneously, and the working status of each compartment can be intelligently controlled according to actual needs.

[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
