[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a soil total nitrogen detection kit, including a hollow box 1 and a connecting belt 12, a driving motor 20 is fixedly connected to the middle of the inner top wall of the hollow box 1, and a driving pulley 19 is fixedly connected to the output end of the driving motor 20, and a driven pulley 14 is rotatably connected to the left side of the inner top wall of the hollow box 1, and the driving pulley 19 is connected to the driven pulley 14 through the connecting belt 12. The bottom of the driven pulley 14 is fixedly connected to the driving bevel gear 16, and the inner wall of the hollow box 1 is rotatably connected to the left side of the inner top wall. A driven bevel gear 15 is connected to the hollow box 1, and the driven bevel gear 15 is meshed with the driving bevel gear 16. A rubber hammer 18 is fixedly connected to the right side of the driven bevel gear 15. A leak box 13 is installed in the middle and upper part of the rear side of the inner wall of the hollow box 1. A grinding mechanism 2 is installed on the inner side of the hollow box 1. The grinding mechanism 2 is used to grind the soil; a feed port 9 is opened on the right side of the top wall of the hollow box 1, and the outer wall of the hollow box 1 is smooth all around; a rotating shaft 5 is rotatably connected to the right side of the top of the feed port 9, and a rotating plate 6 is fixedly connected to the middle of the rotating shaft 5;
[0031] Specifically, when conducting soil total nitrogen detection, the operator turns the rotating plate 6 to open the feed port 9, so that the soil sample can smoothly enter the leakage box 13; the leakage box 13 is designed to have excellent sealing and sufficient capacity to ensure that the soil sample will not be contaminated or lost during storage; then the drive motor 20 is started; driven by the drive motor 20, the driving pulley 19 starts to rotate; through the close connection of the connecting belt 12, the driven pulley 14 and the driving pulley 19 achieve synchronous rotation; this belt transmission method is not only stable and reliable, but also can effectively reduce energy loss; as the driven pulley 14 rotates, the main pulley connected to it The driven bevel gear 16 also starts to rotate; the driven bevel gear 15 and the active bevel gear 16 are precisely meshed to achieve force transmission and motion conversion; this bevel gear transmission method has the advantages of stable transmission ratio and large load-bearing capacity. Under the transmission of the bevel gear, the driven bevel gear 15 drives the rubber hammer 18 to rotate synchronously; the rotation of the rubber hammer 18 produces a strong collision with the leakage box 13, causing the soil sample in the leakage box 13 to shake violently; this shaking not only makes the soil loose, which is convenient for subsequent digestion and detection, but also can effectively destroy the aggregate structure in the soil, thereby improving the accuracy of the detection results. The model of the drive motor 20 is PMDC Motor.
[0032] Reference Figure 1 , Figure 2 and Figure 3The grinding mechanism 2 includes a grinding disc 203, the top of which is fixedly connected to the bottom of the driving pulley 19, a receiving drawer 206 is fixedly connected to the middle of the rear side of the inner wall of the hollow box 1, a feeding drawer 205 is fixedly connected to the middle and lower part of the rear side of the inner wall of the hollow box 1, a fixed disc 204 is fixedly connected to the inner rear side of the hollow box 1, and a heating wire 202 is installed on the inner side of the leakage box 13; a storage box 11 is slidably connected to the right side of the inner side of the hollow box 1, and a handle 10 is fixedly connected to the right side of the storage box 11; air bags 17 are installed at both ends of the rubber hammer 18, and a fan 201 is installed on the top of the rear side of the inner wall of the hollow box 1;
[0033] Specifically, at the beginning of the test, the staff will inject an appropriate amount of copper sulfate solution into the storage box 11; then, by operating the handle 10, the storage box 11 is pushed into the designated position of the hollow box 1; once the storage box 11 is in place, the rubber hammer 18 begins to accurately knock on the leakage box 13; this knocking is not a simple physical vibration, but is carefully calculated and adjusted to produce sufficient collision and friction between soil particles; at the same time, the heating wire 202 and the fan 201 are started synchronously; the fan 201 rotates at a high speed, driving the air flow, and transferring heat evenly to the soil; this blowing of hot air not only helps to dry the soil quickly, but also prevents the soil particles from sticking together due to moisture during the grinding process; as the knocking and heating proceed, the dry soil particles gradually fall off the leakage box 13 and fall into the receiving drawer 206; the design of the receiving drawer 206 is very clever, it has A certain inclination angle allows the soil particles to slide smoothly into the middle gap of the grinding disc 203; at this time, the active pulley 19 starts to rotate, driving the grinding disc 203 to rotate at high speed; the close fit and mutual friction between the grinding disc 203 and the fixed disc 204 allow the soil particles to be fully ground; this grinding process not only makes the soil particles finer, but also can further remove impurities and moisture therein; the ground soil powder eventually falls on the feed bin 205 and slides into the storage box 11 again; copper sulfate reacts chemically with the soil powder to release nitrogen; by measuring the nitrogen content, the total nitrogen content in the soil can be accurately calculated; the design of this soil total nitrogen detection device fully considers the influence of soil moisture on the detection results; through steps such as heating and grinding, moisture and impurities in the soil are effectively removed, thereby improving the accuracy of the detection.
[0034] Reference Figure 1 , shoulder straps 3 are installed at the left and right ends of the front side of the hollow box 1, and an adjusting knob 4 is installed at the end of the shoulder strap 3; the top front side of the hollow box 1 is connected to an exhaust pipe 8, and a valve 7 is installed on the outside of the exhaust pipe 8;
[0035] Specifically, the tightness of the shoulder strap 3 can be adjusted by adjusting the knob 4 , and at the same time, the hollow box 1 can be carried on the shoulder by the shoulder strap 3 to move, and the valve 7 can be opened to discharge excess heat through the exhaust pipe 8 .
[0036] Working principle: When testing total nitrogen in soil, turn the rotating plate 6 to leak out the feed port 9, put the soil into the leakage box 13 for storage, turn on the driving motor 20 to drive the active pulley 19 to rotate, the rotation of the active pulley 19 is linked to the driven pulley 14 through the connecting belt 12 to rotate synchronously, the rotation of the driven pulley 14 also rotates the active bevel gear 16, the rotation of the active bevel gear 16 is meshed with the driven bevel gear 15, thereby driving the driven bevel gear 15 and the rubber hammer 18 to rotate synchronously, the rotation of the rubber hammer 18 collides with the leakage box 13, causing the soil in the leakage box 13 to shake, thereby making it loose;
[0037] And when detecting the total nitrogen in the soil, copper sulfate is injected into the storage box 11 and pushed into the hollow box 1 through the handle 10. When the rubber hammer 18 knocks the leakage box 13, the heating wire 202 and the fan 201 are turned on simultaneously. The fan 201 drives the air to blow toward the soil, and at the same time brings heat to the soil to dry it. The soil is made to collide with each other through the knocking vibration, so that the dry particles fall from the leakage box 13 into the receiving bin 206, and slide through the receiving bin 206 to the middle gap of the grinding disc 203. The rotation of the synchronous driving pulley 19 causes the grinding disc 203 to rotate, and the rotation of the grinding disc 203 rubs against the fixed disc 204, so that the soil particles between them are ground, and finally the soil powder falls on the feeding bin 205, slides into the storage box 11 to react with copper sulfate.
