Description

Technical Field

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

[0002] In the process of agricultural production, the quality of soil is crucial. Fertilizers are often added to supplement nutrients, and soil fertilizer detection is the key technology for controlling the amount of fertilizer added. In the prior art, a soil fertilizer detector is usually used to detect the soil, and the content of specific components in the soil is determined by measuring the absorbance of light of the soil solution.

[0003] Good soil quality determines vigorous crop growth. However, excessive or insufficient nutrients will lead to poor crop growth. At present, there is widespread blind fertilization in the planting industry in China. Before fertilization, farmers do not know how much fertilizer the soil actually needs as a supplement at all. The direct consequence is that crops cannot grow well to the maximum extent. Therefore, so-called detectors have emerged on the market.

[0004] The general detection process is to place a colorimetric cuvette containing a soil sample into a colorimetric cell, irradiate the colorimetric cuvette with a light source, and the light is received by a photoelectric sensor after passing through the colorimetric cell, and the light absorbance of the soil is judged, and then the soil fertilizer concentration is measured. Application No.: CN202122020322.0 discloses a soil fertilizer detection device that can synchronously place multiple colorimetric cuvettes for detection, and has a simple structure and is convenient for installation, which has the effect of improving its use convenience.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , where Figure 1 FIG. 1 is a schematic structural diagram of a preferred embodiment of a soil fertilizer detection device provided by the utility model; Figure 2 is Figure 1Schematic enlarged view of the structure of area A shown; Figure 3 is Figure 1 Schematic diagram of the structure of the sleeve sectional view shown; Figure 4 is Figure 3 Schematic enlarged view of the structure of area B shown; Figure 5 is Figure 1 Schematic diagram of the overall structure of the device shown, a soil fertilizer detection device, including: a crusher 1, a quantitative component 2 is arranged at the bottom of the crusher 1, and a sampling component 3 is arranged at the bottom of the quantitative component 2;

[0025] The quantitative component 2 includes a box body 21 arranged at the discharge port at the bottom of the crusher 1, an electric control valve 22 is arranged at the top of the box body 21, a measuring plate 23 is rotatably arranged on the left side of the inner wall of the box body 21, a slot 24 is arranged inside the box body 21, and a measuring block 25 is slidably arranged on the right side at the bottom of the measuring plate 23 inside the slot 24, and a trigger button 26 is arranged on the left side of the inner wall of the box body 21 and below the measuring plate 23;

[0026] A scraping plate is also arranged inside the crusher 1 for scraping the surface of the roller; in order to save the preparation time of soil test samples, the soil clods are put into the crusher 1 to break them up, which improves and facilitates the subsequent mixing with the nitrogen, phosphorus and potassium combined leaching agent. After the crushing is completed, the soil falls to the bottom of the crusher 1, passes through the electric control valve 22 and falls above the measuring plate 23. When the weight of the soil reaches the limit supported by the measuring block 25, the measuring block 25 moves to the right and the measuring plate 23 rotates to make the soil fall and start the trigger button 26, and the trigger button 26 closes the electric control valve 22.

[0027] The sampling component 3 includes a sleeve 31 arranged on the left side of the box body 21, a sampling tube 32 is connected to the right end of the sleeve 31 and inside the box body 21, the right end of the sampling tube 32 is connected to the inside of the box body 21, a fixing plate 33 is vertically arranged inside the sampling tube 32, two sliding rods 34 are horizontally arranged on the right side of the fixing plate 33, and a first rubber plug 35 is slidably arranged on the circumferential side of the two sliding rods 34 along their length directions, and the right end of the first rubber plug 35 abuts against the connection between the sampling tube 32 and the inside of the box body 21.

[0028] A filter screen is also arranged at the connection between the sampling tube 32 and the inside of the box body 21 for filtering impurities in the detection liquid so as not to affect the detection accuracy; by pulling out the piston rod 37 outwards, the air pressure inside the sleeve 31 is reduced, and then the first spring 36 is retracted under the action of the external air pressure, and then the first rubber plug 35 moves leftward on the two sliding rods 34, and at this time the mixed soil test liquid flows into the sampling tube 32 and the inside of the sleeve 31 to complete the sampling.

[0029] On the right side of the measuring block 25 and inside the slotted groove 24, a tension spring 27 is provided. A threaded push plate 28 is rotatably provided at the right end of the tension spring 27. The circumferential side of the threaded push plate 28 is threadedly connected to the inside of the slotted groove 24.

[0030] By rotating the threaded push plate 28, its left end moves leftward inside the slotted groove 24, thereby pushing the tension spring 27 to deform and squeeze to the left. As a result, a greater weight is required when the measuring block 25 moves to the right, thus adjusting the amount of soil component falling into the leaching agent.

[0031] Inside the first rubber plug 35, a first spring 36 is provided. The left end of the first spring 36 is fixedly connected to the right side of the fixing plate 33. A piston rod 37 is slidably provided left and right inside the sleeve 31.

[0032] The sampling assembly 3 further includes a sample outlet pipe 38 provided on the right side of the bottom of the sleeve 31. At the bottom of the inner wall of the sample outlet pipe 38, two limiting slide rods 39 are provided on the left and right. A second rubber plug 4 is slidably provided up and down along the height direction of the circumferential sides of the two limiting slide rods 39. At the bottom of the inner wall of the sample outlet pipe 38 and inside the second rubber plug 4, a second spring 5 is provided. The top of the second rubber plug 4 abuts against the connection between the sample outlet pipe 38 and the sleeve 31.

[0033] After the piston rod 37 pulls the soil sample solution into the inside of the sleeve 31, the piston rod 37 is pushed to squeeze the soil sample solution. Under the action of pressure, the first rubber plug 35 will firmly adhere to the connection. At this time, the soil sample solution squeezes the second rubber plug 4 and presses it down. When its height is lower than the left outlet, the soil leaching agent is discharged. The tester directly collects it into a colorimetric dish and puts the colorimetric dish into a relevant detection device to complete the soil fertilizer detection.

[0034] The quantitative assembly 2 further includes a rocking rod 29 rotatably provided horizontally at the top right of the box body 21. The left end of the rocking rod 29 penetrates the right side of the box body 21 and extends into its interior. A rope storage disc 6 is provided at the left end of the rocking rod 29. The rope inside the rope storage disc 6 is fixedly connected to the top right of the measuring plate 23.

[0035] After the detection is completed, by rotating the rocking rod 29 to drive the rope storage disc 6 to rotate, the measuring plate 23 is pulled to rotate upward for resetting.

[0036] A stirring frame 7 is rotatably provided horizontally at the bottom of the inner wall of the box body 21. A drive motor 8 for driving the stirring frame 7 to rotate is provided on the right side of the box body 21. The bottom of the box body 21 is communicated with a discharge valve.

[0037] Through the setting of the stirring frame 7, the soil powder and the nitrogen, phosphorus and potassium combined leaching agent can be fully mixed, improving the detection accuracy. Through the setting of the discharge valve, when the test is completed, the discharge valve is opened to discharge the waste liquid inside.

[0038] The working principle of a soil fertilizer detection device provided by the present utility model is as follows:

[0039] The first step: When in use, the soil block to be detected is put into the pulverizer 1 to break it up, making it easier to mix with the nitrogen, phosphorus and potassium combined leaching agent subsequently. After being broken up, the soil falls to the bottom of the pulverizer 1, passes through the electric control valve 22 and falls above the metering plate 23. When the weight of the soil reaches the limit supported by the metering block 25, the metering block 25 moves to the right and the metering plate 23 rotates, causing the soil to fall and triggering the trigger button 26. The trigger button 26 closes the electric control valve 22.

[0040] The second step: The rotation of the output end of the driving motor 8 drives the rotation of the stirring frame 7, thereby fully mixing the soil powder and the nitrogen, phosphorus and potassium combined leaching agent to improve the detection accuracy. When the stirring time reaches the requirement, by pulling out the piston rod 37 outwards, the air pressure inside the sleeve 31 is reduced, and then under the action of the external air pressure, the first spring 36 retracts, causing the first rubber plug 35 to move leftward on the two sliding rods 34. At this time, the mixed soil test solution flows into the sampling tube 32 and the inside of the sleeve 31, and then the piston rod 37 is pushed to squeeze the soil test solution. Under the action of the pressure, the first rubber plug 35 will firmly adhere to the connection point. At this time, the soil test solution squeezes the second rubber plug 4 and presses it down. When its height is lower than the left outlet, the soil leaching agent is discharged, and the tester directly collects it into a colorimetric dish and puts the colorimetric dish into the relevant detection device to complete the soil fertilizer detection.

[0041] Compared with the related technology, a soil fertilizer detection device provided by the present utility model has the following beneficial effects:

[0042] Through the setting of the pulverizer 1, the time for grinding the soil into powder is saved. Through the setting of the quantitative component 2, the control of the soil dosage during each detection is saved. Moreover, through the setting of the stirring frame 7 and the sampling component 3, the test solution to be detected can be quickly taken out. The structure is simple and practical. The tester only needs to put the soil into the pulverizer 1 and use a colorimetric dish to collect the test solution after the device finishes processing. The device greatly saves the preparatory work in the soil fertilizer detection steps, improves the overall detection speed, and has a good use effect.

[0043] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
