Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a soil dilution device for soil detection. Background Art

[0002] Soil is one of the important natural resources on the earth's surface and is of great significance to agricultural production, ecological environment, water resources management, etc. However, due to the influence of human activities, fertilizer application, industrial emissions and other factors, soil pollution and degradation problems are becoming increasingly serious, posing a serious threat to human health and the ecosystem. Therefore, it is crucial to test and monitor the soil and timely understand the quality status of the soil in order to take effective protection and restoration measures. The soil dilution device for soil testing is a device used to mix and dilute soil samples with water or other solutions, so that harmful substances or nutrients in the soil are dissolved in the solution, and then the components in the solution are analyzed and tested by measuring instruments to understand the nature and quality of the soil.

[0003] After searching, Chinese patent number CN201821386142.6 discloses a soil dilution device for soil testing, including an operating platform, on which a small electronic scale, a support frame and paper are arranged, and the support frame and paper can be assembled to form a soil weighing and holding device for holding soil; it also includes a turntable driven by a motor, and a soil dilution cup is supported by a support rod near the edge of the turntable, and a plurality of free stirring balls are arranged in the soil dilution cup. The motor can drive the turntable and drive the soil dilution cup to rotate so that the plurality of free stirring balls roll and stir.

[0004] The beneficial effects of the above device are: simple and convenient operation, and the soil can be diluted more thoroughly and efficiently.

[0005] Although the existing soil dilution device can break the soil into smaller particles and improve the dissolution efficiency between the soil and the dilution solution, the existing dilution device directly mixes the soil to be diluted and the dilution solution before working. Even after the soil is broken, when the volume of the soil to be diluted is too large, it is impossible to ensure sufficient mixing between the soil and the dilution solution, resulting in low soil dilution efficiency. To this end, we propose a soil dilution device for soil testing. Utility Model Content

DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A soil dilution device for soil testing, wherein a mounting plate 2 is fixedly connected to the inner wall of an outer container 1, a crushing barrel 3 is hingedly mounted on the surface of the mounting plate 2, the outer container 1, the mounting plate 2, and the crushing barrel 3 are arranged in concentric circles, and a dilution bin 4 is arranged inside the outer container 1 below the crushing barrel 3. When the device needs to dilute the soil, soil blocks are added to the crushing barrel 3, and a crushing mechanism is installed inside the crushing barrel 3, and the soil blocks are further crushed by the crushing mechanism, so that the soil blocks are broken into fine particles, which is convenient for mixing the soil blocks and the dilution solution.

[0025] The lower end surface of the crushing barrel 3 is fixedly connected with a discharge port 8, and a filter screen 9 is installed inside the discharge port 8. The crushed soil particles are further filtered through the filter screen 9, so that the fine soil particles enter the dilution bin 4 through the discharge port 8, thereby realizing the subsequent soil dilution operation. The lower end surface of the outer container 1 is fixedly connected with a motor 5, and a connecting shaft 6 is inserted inside the outer container 1. The output shaft of the motor 5 is connected to the connecting shaft 6 by transmission. The connecting shaft 6 is inserted inside the dilution bin 4, and the upper end of the connecting shaft 6 passes through the inside of the crushing barrel 3. The crushing mechanism includes a crushing roller 7 connected to the surface of the connecting shaft 6. When the soil blocks are put into the crushing barrel 3, the motor 5 is turned on to drive the connecting shaft 6 to rotate, and the crushing roller 7 is further driven by the connecting shaft 6 to rotate to hit and crush the protrusions inside the crushing barrel 3, so that the soil blocks are turned into fine particles.

[0026] A liquid injection mechanism is installed on one side surface of the outer container 1, and the liquid injection mechanism includes a liquid injection tube 21 connected to the surface of the outer container 1, one end of the liquid injection tube 21 is connected to the inside of the dilution bin 4, and the other end of the liquid injection tube 21 is connected to a liquid storage tube 22, and the liquid storage tube 22 is used to store the diluted solution. The liquid injection mechanism also includes a mounting seat 16 connected to the surface of the outer container 1, and a driven pulley 17 is hingedly installed on the surface of the mounting seat 16, and a threaded rod 20 is inserted inside the driven pulley 17, and the threaded rod 20 and the driven pulley 17 are connected by threads. The lower end surface of the threaded rod 20 is fixedly connected to a piston 23, and the piston 23 is adapted to be inserted inside the liquid storage tube 22. The upper end of the connecting shaft 6 passes through the top of the crushing barrel 3 and is fixedly connected to a driving pulley 18, and the driven pulley 17 and the driving pulley 18 are connected by a connecting belt 19. After the motor 5 is further turned on, the crushing mechanism and the injection mechanism are driven to operate synchronously, so that after the crushing roller 7 crushes the soil blocks and filters them into the dilution bin 4 through the filter screen 9, the injection mechanism simultaneously injects the dilution solution inside the storage tube 22 into the dilution bin 4 through the injection tube 21, so that the dilution solution can be mixed with the soil particles to achieve soil dilution.

[0027] When the connecting shaft 6 rotates, the driving pulley 18 is driven to rotate, and the driving pulley 18 drives the driven pulley 17 to rotate through the connecting belt 19. During the rotation process, the driven pulley 17 engages with the threaded rod 20 to rotate, further causing the threaded rod 20 to slide linearly inside the driven pulley 17, and the threaded rod 20 pushes the piston 23 to slide linearly inside the liquid storage tube 22, so that the piston 23 squeezes the dilution solution inside the liquid storage tube 22 during the downward sliding process inside the liquid storage tube 22, and further causes the dilution solution inside the liquid storage tube 22 to be ejected through the one-way valve at the front end opening of the injection tube 21, thereby realizing the injection of the dilution solution into the dilution chamber 4.

[0028] The dilution bin 4 is provided with a stirring mechanism, which includes a stirring roller 11 connected to the surface of the connecting shaft 6, and the stirring roller 11 is installed inside the dilution bin 4. After the soil particles crushed and filtered inside the crushing barrel 3 enter the dilution bin 4, when the soil particles and the dilution solution are mixed, the mixture can be stirred by the stirring roller 11, so as to further achieve full dilution of the soil and improve the dilution efficiency of the soil.

[0029] The lower end surface of the crushing barrel 3 is equipped with a driving mechanism, which is used to drive the crushing barrel 3 to rotate on the surface of the mounting plate 2, so that the discharge port 8 and the through hole 10 can be periodically aligned. The driving mechanism includes an inner gear ring 13 connected to the lower end surface of the crushing barrel 3, a control gear 12 is fixedly connected to the surface of the connecting shaft 6, and a connecting rod 14 is fixedly connected to the inner wall of the outer container 1. A connecting gear 15 is hingedly installed on the surface of the connecting rod 14. The connecting gear 15 is located between the control gear 12 and the inner gear ring 13, and the connecting gear 15 is meshed and connected with the control gear 12 and the inner gear ring 13 at the same time. When the connecting shaft 6 is turned on, the control gear 12 is driven to rotate, so that the control gear 12 meshes with the connecting gear 15 to rotate, and the inner gear ring 13 is meshed through the connecting gear 15 to rotate. Further, in the process of driving the crushing roller 7 to rotate, the connecting shaft 6 synchronously drives the crushing barrel 3 to rotate, so that the soil blocks inside the crushing barrel 3 can fully contact with the crushing roller 7 under the action of the centrifugal force formed by the rotation of the crushing barrel 3, and the crushing effect of the crushing roller 7 on the soil blocks is further improved. The inner wall of the lower end of the crushing barrel 3 is set to be conical, so that during the rotation of the crushing barrel 3, the soil particles inside the crushing barrel 3 slide outward and flow to the side of the discharge port 8 through the inner wall of the lower end of the crushing barrel 3.

[0030] At the same time, the surface of the mounting plate 2 is provided with through holes 10. When the crushing barrel 3 is rotating, the discharge port 8 will periodically align with the through hole 10, further making the filter screen 9 filter the soil particles. Only when the discharge port 8 and the through hole 10 coincide and align, the soil particles in the crushing barrel 3 will fall into the dilution bin 4 through the through hole 10, further making the soil particles input in batches, avoiding the one-time input of a large amount of soil particles, resulting in an inappropriate ratio of soil particles and dilution solution, resulting in poor soil dilution effect. The through holes 10 are arranged in a plurality of groups with equal distances and circumferential distribution. By setting the number of through holes 10, the efficiency of the crushing barrel 3 in inputting the crushed soil particles can be increased, and the dilution efficiency of the device on the soil can be further increased.

[0031] The surface of the connecting shaft 6 is fixedly connected with a scraper 24, which is inserted into the inside of the dilution chamber 4. The scraper 24 is set in an "L" shape and abuts against the inner wall of the outer container 1. When the connecting shaft 6 rotates, the scraper 24 is driven to rotate against the inside of the outer container 1, and the soil adhered to the inner wall of the outer container 1 is further scraped off, thereby cleaning the inner wall of the outer container 1 and improving the mixing effect of the soil and the dilution solution.
