[0002] The soil insect quantity detection equipment is a portable detection tool for quickly measuring the density of insect organisms in soil. Through technologies such as optical recognition, conductivity sensing, or vibration detection, this device can complete the detection within 5 - 10 minutes in the field and directly display or transmit the insect quantity data. Compared with traditional laboratory detection methods, it has the characteristics of low cost, simple operation, and strong immediacy, and can be widely applied in fields such as agricultural planting, ecological research, and soil health assessment, helping users quickly master the soil biological activity status and providing a scientific basis for precise farming and ecological protection.

[0003] The existing soil insect number detection equipment has a relatively auxiliary structure. Usually, a box is carried, and inside the box, there are a sampling cylinder, a collection cylinder, an insect counter, etc. Although the device is relatively complete and has high detection accuracy, it is large in volume and inconvenient to carry. At the same time, the use cost is high, and the later maintenance cost is high, making it not suitable for large-scale use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a portable detection device for measuring the number of insects in soil.

[0005] The technical solution adopted to solve the above technical problem is: A portable detection device for measuring the number of insects in soil, including a sampling cylinder, and an installation cylinder is provided at the top of the sampling cylinder, and a power supply component is installed inside the installation cylinder;

[0006] The bottom of the power supply component is installed with a heating component, a threaded sleeve is provided between the sampling cylinder and the installation cylinder, and a collection cylinder is provided at the bottom of the sampling cylinder;

[0007] A partition component is installed inside the collection cylinder, a threaded cover is provided at the bottom of the collection cylinder, and a sampling ring knife is provided inside the threaded cover.

[0008] Further, the inner wall bottom end of the sampling cylinder is provided with a first internal thread, the outer wall top end of the sampling cylinder is provided with a first external thread, both sides of the top of the sampling cylinder are provided with first through holes, the center of the top of the sampling cylinder is provided with a second through hole, both sides of the two first through holes are provided with limiting grooves, the outer wall front end of the sampling cylinder is provided with scales, the threaded cover matches the first external thread, and the first internal thread can be threadedly connected with the collection cylinder.

[0009] Through the above technical solution, assembly is achieved. The first external thread is threadedly connected to the threaded sleeve, realizing the assembly of the sampling cylinder and the mounting cylinder. When collecting soil with the sampling cylinder, the threaded cap is removed from the bottom of the collecting cylinder and threadedly connected to the first external thread, thereby blocking the two first through holes and the second through hole, preventing soil from flowing out of the two first through holes and the second through hole when the sampling cylinder is placed upside down after collecting the soil. At the same time, the sampling ring cutter is removed from the bottom of the collecting cylinder and threadedly connected to the first internal thread, thereby installing the sampling ring cutter at the bottom of the sampling cylinder. The staff can rotate the sampling cylinder to drive the sampling ring cutter to rotate, realizing the excavation of the ground soil. The staff can observe the scale to collect soil at different depths, which is convenient for soil collection.

[0010] Further, a top cover is fixedly connected to the top of the mounting cylinder. Two third through holes are opened on both sides of the bottom of the mounting cylinder, and a fourth through hole is opened at the center of the bottom of the mounting cylinder. The outer wall bottom end of the mounting cylinder is threadedly connected to the second external thread.

[0011] Through the above technical solution, when removing the mounting cylinder, directly rotate the threaded sleeve to separate the threaded sleeve from the first external thread, realizing the separation of the sampling cylinder and the mounting cylinder. After collecting the soil, when installing the mounting cylinder, rotate the threaded sleeve so that the threaded sleeve can be threadedly connected to both the first external thread and the second external thread, thus realizing the assembly of the sampling cylinder and the mounting cylinder.

[0012] Further, in the combined state, the threaded sleeve is threadedly connected to the first external thread and the second external thread.

[0013] Through the above technical solution, it is convenient to disassemble and assemble the sampling cylinder and the mounting cylinder, and the operation is simple.

[0014] Further, the power supply assembly includes a battery pack fixedly installed on the inner surface of the bottom of the mounting cylinder. Power connection seats are fixedly connected to both sides of the bottom of the battery pack, and a lamp holder is fixedly connected to the center of the bottom of the battery pack. A switch button and a display screen are respectively installed on the front end of the outer wall of the mounting cylinder. In the combined state, the lamp holder passes through the fourth through hole and the first through hole.

[0015] Through the above technical solution, when the staff detects the number of insects in the collected soil, turn on the switch button, the battery pack powers the lamp holder, and the lamp holder lights up. According to the light avoidance property, the insects in the soil in the sampling cylinder drill downward, which is convenient for insect detection. At the same time, the display screen shows the battery power, which is convenient for use.

[0016] Further, the heating assembly includes springs fixedly connected to both sides of the bottom of the battery pack. The bottom ends of the two springs are fixedly connected with first limiting plates. The bottoms of the two first limiting plates are fixedly connected with limiting sleeves. The bottoms of the two limiting sleeves are fixedly connected with second limiting plates. Two limiting bars are fixedly connected between the two first limiting plates and the corresponding second limiting plates. A set of limiting rods are fixedly connected to the bottoms of the two second limiting plates. The bottom ends of the two sets of limiting rods are fixedly connected with conical heads. Heating rods are fixedly installed on the tops of the two conical heads. Electric connectors are fixedly connected to the tops of the two heating rods.

[0017] Through the above technical solution, after the soil is collected, the two heating rods need to be inserted into the soil. At this time, it is convenient to insert through the conical heads. After inserting to a certain depth, the conical heads push the heating rods under force, so that the heating rods push the electric connectors, making the electric connectors inserted into the power connection sockets, enabling the heating rods to be powered on, realizing heating of the soil, and the worms drill downward according to the heat avoidance property, which is convenient for measuring worms.

[0018] Further, the two springs are respectively located in the corresponding third through holes. The two first limiting plates are respectively located at the tops of the corresponding first through holes. The multiple limiting bars are respectively slidably connected with the corresponding limiting grooves. The tops of the two heating rods respectively penetrate through the corresponding limiting sleeves and are fixedly connected with the corresponding first limiting plates.

[0019] Through the above technical solution, during the upward pushing process of the heating rods, the second limiting plates, the limiting sleeves and the corresponding limiting bars are driven to move. The limiting sleeves and the corresponding limiting bars provide their stability. When the second limiting plates are close to the bottoms of the corresponding limiting grooves, at this time the electric connectors are just inserted into the power connection sockets. When the entire installation cylinder is removed, at this time the two heating rods are taken out of the soil, and the springs are reset by elastic force, pushing the first limiting plates, driving the electric connectors to separate from the power connection sockets, and at this time the heating rods are not powered on, providing its service life.

[0020] Further, the inner wall bottom end of the collection cylinder is provided with a second internal thread, and the inner wall top end of the collection cylinder is provided with a third internal thread.

[0021] Through the above technical solution, the collection cylinder is threadedly connected with the separation assembly through the third internal thread to achieve assembly. Ethanol is provided at the bottom end inside the collection cylinder, which can kill the worms that fall from the separation assembly. Later, the separation assembly is disassembled and the worms are poured out for convenient counting.

[0022] Further, the separation component includes a funnel disposed at the center inside the collection cylinder. A discharge pipe is fixedly connected to the center of the bottom of the funnel. The outer wall top of the funnel is provided with a third external thread. A gauze is fixedly installed at the center of the funnel. A wire mesh is fixedly installed near the top of the gauze at the center of the funnel. In the combined state, the third external thread is threadedly connected to the bottom end of the third internal thread, and the third external thread is threadedly connected to the top end of the first internal thread.

[0023] Through the above technical solution, the funnel is threadedly connected to the collection cylinder through the third external thread to achieve assembly with the collection cylinder, and at the same time is threadedly connected to the first internal thread to achieve assembly with the sampling cylinder. When measuring the worms, the worms in the sampling cylinder drill through the wire mesh and the gauze under the action of light and high temperature, and fall into the collection cylinder through the funnel and the discharge pipe to achieve measurement. At the same time, the wire mesh and the gauze are used to support the soil to prevent the soil from falling into the collection cylinder through the funnel, playing an isolation role.

[0024] Further, the outer wall top of the sampling core cutter is provided with a fourth external thread, and the outer wall bottom of the sampling core cutter is provided with a fifth external thread. In the combined state, the fourth external thread is threadedly connected to the second internal thread, the fifth external thread is threadedly connected to the threaded cap, and the fourth external thread matches the first internal thread.

[0025] Through the above technical solution, when collecting soil, the sampling core cutter is installed at the bottom of the sampling cylinder, so that the fourth external thread is threadedly connected to the first internal thread, which is not only convenient for collecting soil, but also prevents the soil from penetrating into the first internal thread. Since the sampling cylinder needs to be assembled with the collection cylinder after each soil collection, the first internal thread is protected, and the sealing performance of the assembly of the sampling cylinder and the collection cylinder is improved. When the sampling core cutter is not in use, the sampling core cutter is directly installed at the bottom of the collection cylinder, so that the fourth external thread is threadedly connected to the second internal thread, and at the same time the threaded cap is threadedly connected to the fifth external thread, preventing the sampling core cutter from being exposed outside and affecting the handling. At the same time, the threaded cap has a supporting effect and can be placed flat on the table, making the overall convenience high.

[0026] The beneficial effects of the present invention are as follows: (1) By designing the sampling cylinder, the sampling core cutter and the threaded cap, when the sampling cylinder collects soil, the sampling core cutter can be directly installed at the bottom of the sampling cylinder, and the threaded cap is installed at the top of the sampling cylinder, which is not only convenient for soil collection, but also prevents the soil from penetrating into the upper thread of the sampling cylinder, protects the internal thread of the sampling cylinder, improves the sealing performance of the assembly of the sampling cylinder and the collection cylinder, and the whole device is convenient to assemble and has strong practicability; (2) By designing the installation cylinder, the power supply component and the heating component, it is convenient to drive the worms, so that the worms quickly drill into the collection cylinder, which is convenient for counting them; (3) By designing the collection cylinder and the separation component, the soil is supported by the wire mesh and the gauze to prevent the soil from falling into the collection cylinder, which is convenient for collecting the worms. At the same time, the collection cylinder can be conveniently disassembled and assembled with the sampling cylinder, and the convenience is high. Brief Description of the Drawings

The first external thread 12 is threadedly connected to the threaded sleeve 5 to achieve the assembly of the sampling cylinder 1 and the mounting cylinder 2. When the sampling cylinder 1 collects soil, the threaded cap 9 is removed from the bottom of the collection cylinder 6 and threadedly connected to the first external thread 12, so as to block the two first through holes 13 and the second through hole 14, preventing the soil from flowing out of the two first through holes 13 and the second through hole 14 when the sampling cylinder 1 is placed upside down after collecting the soil. At the same time, the sampling ring cutter 8 is removed from the bottom of the collection cylinder 6 and threadedly connected into the first internal thread 11, so as to install the sampling ring cutter 8 at the bottom of the sampling cylinder 1. The staff can rotate the sampling cylinder 1 to drive the sampling ring cutter 8 to rotate to achieve the excavation of the ground soil. The staff can observe the scale 16 to collect soil at different depths, which is convenient for soil collection.

[0043] As Figures 1 - 6As shown in the figure, an installation cylinder 2 is provided at the top of the sampling cylinder 1. A top cover 21 is fixedly connected to the top of the installation cylinder 2. Two third through holes 22 are opened on both sides of the bottom of the installation cylinder 2, and a fourth through hole 23 is opened at the center of the bottom of the installation cylinder 2. An external second thread 24 is threadedly connected to the bottom end of the outer wall of the installation cylinder 2. When removing the installation cylinder 2, directly rotate the threaded sleeve 5 so that the threaded sleeve 5 is separated from the external first thread 12, realizing the separation of the sampling cylinder 1 and the installation cylinder 2. After collecting the soil, when installing the installation cylinder 2, rotate the threaded sleeve 5 so that the threaded sleeve 5 can be threadedly connected to both the external first thread 12 and the external second thread 24, thus realizing the assembly of the sampling cylinder 1 and the installation cylinder 2. In the combined state, the threaded sleeve 5 is threadedly connected to the external first thread 12 and the external second thread 24, facilitating the disassembly and assembly of the sampling cylinder 1 and the installation cylinder 2, and the operation is simple.

[0044] As Figures 1 - 13 shown, a power supply assembly 3 is installed in the installation cylinder 2. The power supply assembly 3 includes a battery pack 301 fixedly installed on the inner surface of the bottom of the installation cylinder 2. Power connection seats 302 are fixedly connected to both sides of the bottom of the battery pack 301, and a lamp holder 303 is fixedly connected to the center of the bottom of the battery pack 301. A switch button 304 and a display screen 305 are respectively installed on the front end of the outer wall of the installation cylinder 2. In the combined state, the lamp holder 303 passes through the fourth through hole 23 and the first through hole 13. When the staff detects the number of insects in the collected soil, turn on the switch button 304, the battery pack 301 powers the lamp holder 303, and the lamp holder 303 lights up. According to the light avoidance property, the insects in the soil in the sampling cylinder 1 drill downward, facilitating insect measurement. At the same time, the display screen 305 has a power display, which is convenient for use.

[0045] As Figures 1 - 13As shown, a heating component 4 is installed at the bottom of the power supply component 3. The heating component 4 includes springs 401 fixedly connected to both sides of the bottom of the battery pack 301. The bottom ends of the two springs 401 are fixedly connected with first limit plates 402. The bottoms of the two first limit plates 402 are fixedly connected with limit sleeves 403. The bottoms of the two limit sleeves 403 are fixedly connected with second limit plates 404. Two limit bars 405 are fixedly connected between the two first limit plates 402 and the corresponding second limit plates 404. A group of limit rods 406 are fixedly connected to the bottoms of the two second limit plates 404. The bottom ends of the two groups of limit rods 406 are fixedly connected with conical heads 407. Heating rods 408 are fixedly installed on the tops of the two conical heads 407. The tops of the two heating rods 408 are fixedly connected with power connection heads 409. After collecting the soil, it is necessary to insert the two heating rods 408 into the soil. At this time, it is convenient to insert through the conical heads 407. After inserting to a certain depth, the conical heads 407 push the heating rods 408, causing the heating rods 408 to push the power connection heads 409, so that the power connection heads 409 are inserted into the power connection sockets 302, making the heating rods 408 energized to heat the soil. The insects drill downward according to their heat avoidance property, which is convenient for measuring insects. The two springs 401 are respectively located in the corresponding third through holes 22. The two first limit plates 402 are respectively located at the tops of the corresponding first through holes 13. The multiple limit bars 405 are respectively slidably connected with the corresponding limit grooves 15. The tops of the two heating rods 408 respectively penetrate through the corresponding limit sleeves 403 and are fixedly connected with the corresponding first limit plates 402. During the upward pushing process of the heating rods 408, the second limit plates 404, the limit sleeves 403 and the corresponding limit bars 405 are driven to move. The limit sleeves 403 and the corresponding limit bars 405 provide their stability. When the second limit plates 404 are in close contact with the bottoms of the corresponding limit grooves 15, at this time the power connection heads 409 are just inserted into the power connection sockets 302. When the entire installation cylinder 2 is removed, at this time the two heating rods 408 are taken out of the soil. The springs 401 are reset by their elastic force, pushing the first limit plates 402 and driving the power connection heads 409 to separate from the power connection sockets 302. At this time, the heating rods 408 are not energized, extending their service life.

[0046] As Figures 1 - 10 shown, a threaded sleeve 5 is provided between the sampling cylinder 1 and the installation cylinder 2. A collection cylinder 6 is provided at the bottom of the sampling cylinder 1. A second internal thread 61 is provided at the bottom end of the inner wall of the collection cylinder 6. A third internal thread 62 is provided at the top end of the inner wall of the collection cylinder 6. The collection cylinder 6 is threadedly connected with the separation component 7 through the third internal thread 62 to achieve assembly. Ethanol is provided at the bottom end inside the collection cylinder 6, which can kill the insects that fall from the separation component 7. Later, the separation component 7 is disassembled and the insects are poured out for convenient counting.

[0047] As Figures 1 - 10As shown in the figure, a separating component 7 is installed in the collecting cylinder 6. The separating component 7 includes a funnel 701 disposed at the center inside the collecting cylinder 6. A blanking pipe 702 is fixedly connected to the center of the bottom of the funnel 701. A third external thread 703 is provided at the top end of the outer wall of the funnel 701. A gauze 704 is fixedly installed at the center of the funnel 701. A wire mesh 705 is fixedly installed near the top of the gauze 704 at the center of the funnel 701. In the combined state, the third external thread 703 is threadedly connected to the bottom end of the third internal thread 62, and the third external thread 703 is threadedly connected to the top end of the first internal thread 11. The funnel 701 is threadedly connected to the collecting cylinder 6 through the third external thread 703 to achieve assembly with the collecting cylinder 6, and at the same time is threadedly connected to the first internal thread 11 to achieve assembly with the sampling cylinder 1. When measuring insects, the insects in the sampling cylinder 1 drill through the wire mesh 705 and the gauze 704 under the action of light and high temperature, and fall into the collecting cylinder 6 through the funnel 701 and the blanking pipe 702 to achieve measurement. At the same time, the wire mesh 705 and the gauze 704 are used to support the soil to prevent the soil from falling into the collecting cylinder 6 through the funnel 701, playing an isolation role.

[0048] As Figures 1 - 12 shown, a threaded cover 9 is provided at the bottom of the collecting cylinder 6. A sampling core cutter 8 is provided inside the threaded cover 9. A fourth external thread 81 is provided at the top end of the outer wall of the sampling core cutter 8. A fifth external thread 82 is provided at the bottom end of the outer wall of the sampling core cutter 8. In the combined state, the fourth external thread 81 is threadedly connected to the second internal thread 61, and the fifth external thread 82 is threadedly connected to the threaded cover 9. The fourth external thread 81 matches the first internal thread 11. When collecting soil, the sampling core cutter 8 is installed at the bottom of the sampling cylinder 1 so that the fourth external thread 81 is threadedly connected to the first internal thread 11, which is not only convenient for collecting soil, but also prevents the soil from penetrating into the first internal thread 11. Since the sampling cylinder 1 and the collecting cylinder 6 need to be assembled after each soil collection, the first internal thread 11 is protected, and the sealing performance of the assembly of the sampling cylinder 1 and the collecting cylinder 6 is improved. When the sampling core cutter 8 is not in use, the sampling core cutter 8 is directly installed at the bottom of the collecting cylinder 6 so that the fourth external thread 81 is threadedly connected to the second internal thread 61, and at the same time the threaded cover 9 is threadedly connected to the fifth external thread 82, preventing the sampling core cutter 8 from being exposed outside and affecting taking. At the same time, the threaded cover 9 has a supporting effect and can be placed flat on the desktop, making the overall convenience high.

[0049] The working principle of this embodiment is as follows. When collecting soil, the staff first rotates the threaded sleeve 5 to separate the threaded sleeve 5 from the first external thread 12, removes the installation cylinder 2 from the sampling cylinder 1, then rotates the collection cylinder 6 to remove it from the sampling cylinder 1. At this time, the sampling cylinder 1 is single-piece. Rotate the threaded cap 9 to remove it from the bottom of the collection cylinder 6, and then rotate the sampling core cutter 8 to remove it from the bottom of the collection cylinder 6. The threaded cap 9 is removed from the bottom of the collection cylinder 6. At this time, thread the threaded cap 9 onto the first external thread 12 to block the two first through holes 13 and the second through hole 14. At the same time, thread the sampling core cutter 8 into the first internal thread 11 to install the sampling core cutter 8 at the bottom of the sampling cylinder 1. The staff can rotate the sampling cylinder 1 to drive the sampling core cutter 8 to rotate and observe the scale 16 to collect soil at different depths;

[0050] After taking the soil, invert the entire sampling cylinder 1. Due to the sealing of the threaded cap 9, the soil will not flow out through the two first through holes 13 and the second through hole 14. Rotate the sampling core cutter 8 to remove it from the sampling cylinder 1, and then thread the collection cylinder 6 and the funnel 701 onto the first internal thread 11 through the third external thread 703 to assemble the collection cylinder 6, the funnel 701 and the sampling cylinder 1. At this time, place the sampling cylinder 1 upright, and the staff then inserts the two heating rods 408 and the lamp holder 303 into the sampling cylinder 1. At this time, turn on the switch button 304, and the battery pack 301 powers the lamp holder 303, and the lamp holder 303 lights up. According to the light avoidance property, the insects in the soil in the sampling cylinder 1 drill downward. At the same time, after the conical head 407 on the heating rod 408 is inserted into the soil to a certain depth, the conical head 407 forces the heating rod 408, causing the heating rod 408 to push the electrical head 409, so that the electrical head 409 is inserted into the power connection socket 302, making the heating rod 408 energized to heat the soil. The insects drill downward according to the heat avoidance property. The insects drill through the wire mesh 705 and the gauze 704 and fall into the collection cylinder 6 through the funnel 701 and the feed pipe 702. Ethanol is provided at the bottom end inside the collection cylinder 6 to kill the fallen insects;

[0051] Finally, first remove the collection cylinder 6 and the funnel 701 from the sampling cylinder 1, then remove the funnel 701, pour out the insects in the collection cylinder 6 to count them. After measuring the insects, install the installation cylinder 2 and the power supply assembly 3 on the top of the sampling cylinder 1, install the collection cylinder 6 and the partition assembly 7 on the bottom of the sampling cylinder 1, install the sampling core cutter 8 on the bottom of the collection cylinder 6, and install the threaded cap 9 on the bottom of the sampling core cutter 8.

[0052] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
