[0001] This utility model relates to the field of sampling equipment, and in particular to a soil nitrogen content detection and sampling device. Background Technology
[0002] Soil nitrogen content detection and sampling devices are important tools for assessing soil fertility. By detecting the nitrogen content in the soil, they provide key data that helps customers systematically assess soil conditions and optimize fertilization and agricultural management decisions.
[0003] During operation, the sample is at risk of being contaminated by external factors, which directly affects the accuracy of the test results. To ensure the reliability of the test data, we need to strictly keep the sampling equipment clean to avoid introducing contamination during the next sampling. However, most current cleaning methods require disassembling the structure of the device, which is cumbersome and time-consuming, greatly affecting work efficiency and convenience. Therefore, a soil nitrogen content detection sampling device is proposed. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a soil nitrogen content detection and sampling device. It features an internal channel extending into the soil sampling drill bit, allowing for easy connection of a water pipe to the top of the channel after each sampling. Multiple first and second guide channels are evenly distributed at the bottom of the internal channel, directing water flow to the gap between the sampling rod, the drill bit, and the bulldozer handle. External water pressure then thoroughly cleans the interior, improving cleaning efficiency and significantly reducing operational complexity.
[0005] To solve the above-mentioned technical problems, this utility model solves the problem that the soil nitrogen content detection sampling device needs to be disassembled every time it is cleaned, which greatly affects the work efficiency and convenience.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A soil nitrogen content detection and sampling device includes a soil sampling drill bit and a pusher handle mounted on a sampling rod. The pusher handle is connected to a handle and has an internal channel extending into the soil sampling drill bit at its connection point. Multiple first guide grooves and second guide grooves are evenly distributed around the outer circumference of the internal channel.
[0008] Preferably, the first guide channel is formed inside the bulldozer handle, and the second guide channel is formed inside the sampling rod.
[0009] Preferably, the first guide channel, the second guide channel, and the built-in channel can communicate with each other.
[0010] Preferably, one end of the outlet of the second guide channel is provided with a groove, which is opened on the inner wall of the soil sampling drill bit.
[0011] Preferably, the first and second guide channels are constructed with a slope, and the built-in channel has a top opening for connection and a bottom opening for opening.
[0012] Preferably, the opening at the top of the built-in channel is provided with an installation cylinder, and a sealing cap is threadedly connected to the installation cylinder.
[0013] Preferably, a sealing ring is provided at the bottom of the mounting cylinder opening.
[0014] Preferably, a limiting inner ring is connected to the inner wall of the mounting cylinder for limiting.
[0015] Preferably, the soil sampling drill bit is fitted with an outer cover, and the bottom of the outer cover is provided with a base plate with multiple support seats for support.
[0016] Preferably, the outer wall of the soil sampling drill bit is provided with an outer frame and one end of the outer cover cylinder is threaded into it, and the outer wall of the outer cover cylinder is connected with a limiting ring and contacts the bottom of the outer frame.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] The soil nitrogen content detection and sampling device provided in this application has an internal channel inside the bulldozer handle that extends into the soil sampling drill bit. This allows for easy connection of a water pipe to the top opening of the internal channel after each soil sampling. The lower part of the internal channel is evenly provided with multiple first and second guide channels, which can guide the water flow to the gap between the sampling rod, the soil sampling drill bit, and the bulldozer handle. The internal parts are thoroughly cleaned by external water pressure flushing. This method not only improves cleaning efficiency but also significantly reduces operational complexity.
[0019] This application provides an installation nozzle and a sealing cap. The installation nozzle is fixedly installed at the opening at the top of the built-in channel. When not in use, the sealing cap is rotatably connected to the inside of the installation nozzle via a thread to seal the opening of the built-in channel.
[0020] This application improves the sealing performance of the connection by setting a sealing ring and a limiting inner ring, which allows the sealing ring to be tightly pressed into the groove on the mounting cylinder when the sealing cover is connected. The limiting inner ring limits the sealing cover.
[0021] This application improves the cleaning effect on the inner wall of the soil sampling drill bit by setting an outer casing, a base plate, and a support seat to allow the water flow to stay for a period of time. The support seat is used to support the base plate. Attached Figure Description

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.
[0034] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example
[0035] Please see Figure 1 - Figure 7 A soil nitrogen content detection and sampling device includes a soil sampling drill bit 101 and a pusher handle 102 mounted on a sampling rod 1. The pusher handle 102 is connected to a handle 103 and has an internal channel 2 that extends into the soil sampling drill bit 101 at its connection point. Multiple first guide grooves 201 and second guide grooves 202 are evenly distributed around the outer ring of the internal channel 2.
[0036] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The soil nitrogen content detection sampling device of this application is mainly composed of a sampling rod 1, a soil sampling drill bit 101, a bulldozing handle 102, and a handle 103. In the application process, the soil sampling drill bit 101 is the sampling end. After each sampling, in order to facilitate cleaning, an internal channel 2 that can extend into the soil sampling drill bit 101 is directly opened inside the bulldozing handle 102. This allows for easy connection of a water pipe to the top opening of the internal channel 2 after each soil sampling. The lower part of the internal channel 2 is evenly provided with multiple first guide grooves 201 and second guide grooves 202, which are used to guide the water flow to the gap between the sampling rod 1, the soil sampling drill bit 101, and the bulldozing handle 102 during rinsing. The internal parts are thoroughly cleaned by external water pressure. This method not only improves the cleaning efficiency but also significantly reduces the complexity of operation. At the same time, it also ensures the accuracy of the subsequent test results.
[0037] It should also be noted that the corresponding connection between the first guide channel 201, the second guide channel 202 and the slot 203 allows water to flow through each other. At the same time, the first guide channel 201 and the second guide channel 202 both have a certain slope, so that when water flows through, it can be more easily guided into the gap between the sampling rod 1, the soil drilling bit 101 and the bulldozer handle 102, thereby improving the overall cleaning effect.
[0038] This application also includes a slot 203 and an opening 204. The frontal cross-section of the slot 203 is triangular, and its inner wall has a slope. Water flows through the second guide channel 202 and into the slot 203, then flows down to the inner wall of the soil sampling drill bit 101. The number of the first guide channel 201, the second guide channel 202, and the slot 203 are equal. The slots 203 are evenly distributed on the inner wall of the soil sampling drill bit 101. The first guide channel 201 penetrates the bulldozer handle 102, and the second guide channel 202 penetrates the sampling rod 1, so that one end of the second guide channel 202 corresponds to the first guide channel 201, and the other end is aligned with the slot 203. The opening 204 is located at the bottom of the built-in channel 2. The design of the opening 204 is to facilitate the guidance of water flow.
[0039] Please see Figure 4 , Figure 6 and Figure 7 This application also includes an installation port 501 and a sealing cover 5. The installation port 501 is fixedly installed at the opening at the top of the built-in channel 2. When not in use, the sealing cover 5 is rotatably connected to the inside of the installation port 501 to seal the opening of the built-in channel 2.
[0040] This application also includes a sealing ring 502 and a limiting inner ring 503. The sealing ring 502 is glued to the outer ring at the bottom of the sealing cover 5. When the sealing cover 5 is rotated and threaded into the mounting cylinder 501, the sealing ring 502 is pressed tightly into the groove on the mounting cylinder 501, thereby further improving the sealing performance of the connection. The limiting inner ring 503 is fixed to the inner wall of the mounting cylinder 501, thereby limiting the sealing cover 5 when it is rotated into the mounting cylinder 501.
[0041] This application also includes an outer cover cylinder 3, a base plate 301, and a support base 302. The outer cover cylinder 3 is fitted over the outside of the soil sampling drill bit 101, covering the drill bit 101. At the bottom opening of the outer cover cylinder 3, the base plate 301 is connected, preventing the water flowing into the inner wall of the drill bit 101 from flowing out through the side opening. Instead, the water flows out directly through the bottom of the outer cover cylinder 3 and out through the opening of the base plate 301 after rinsing, allowing the water to remain in place for a period of time. This further improves the cleaning effect on the inner wall of the drill bit 101. The support base 302 is evenly distributed at the bottom of the outer cover cylinder 3, supporting the base plate 301 while maintaining a gap between it and the ground, ensuring that wastewater can flow directly to the surrounding area.
[0042] This application also includes an outer frame 4 and a limiting ring 401. The outer frame 4 is fixedly installed on the outer wall of the soil sampling drill bit 101. When the outer cover 3 is fitted onto it and inserted into the outer frame 4, it rotates. The outer cover 3 is provided with a matching thread on the inner wall of the outer frame 4. Therefore, when the outer cover 3 is threaded to the inside of the outer frame 4, the outer cover 3 is fixed as a whole. At the same time, when the outer cover 3 is connected to the inside of the outer frame 4, the limiting ring 401 and the outer cover 3 are designed as an integral structure, so that its upper end face fits against the bottom of the outer frame 4 for limiting during installation.
[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
