Description

Technical Field

[0001] The present invention relates to the technical field of soil testing, in particular to a soil compaction testing device for soybean planting agriculture. Background Art

[0002] Soil compaction refers to the soil's ability to resist external forces such as compaction and fragmentation, and is one aspect of soil properties. Other physical properties of soil include texture, structure, and porosity, which affect soil firmness, plasticity, permeability, drainage, water storage capacity, and root penetration. Soil compaction is composed of soil resistance to shear, compression, and friction, and is a key indicator of soil strength. Agricultural soil sampling is a crucial task in agricultural science. Its purpose is to better and more accurately measure soil compaction, infiltration rate, temperature, humidity, electrical conductivity, and other relevant parameters, thereby further understanding soil properties and improving the farmland soil environment. Soil compaction, a key indicator in modern agricultural production, is frequently measured during crop cultivation. It is well known that compacted soil can prevent water infiltration, reduce fertilizer utilization, and affect plant root growth, leading to reduced crop yields. Therefore, understanding soil compaction is particularly important.

[0003] Currently, when testing soil compaction in soybean cultivation, the test equipment is subject to the reverse force of the soil when encountering hard soil, which can easily cause it to tilt and deflect, affecting the normal soil testing process and resulting in inaccurate soil compaction tests. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A soil compaction testing device for soybean planting agriculture, comprising:

[0006] A frame, and a wheel mounted on the bottom of the frame, a toggle piece fixedly connected to the side of the wheel surface, and a pre-treatment mechanism mounted on the side inside the frame;

[0007] A testing mechanism, the testing mechanism is used to detect the compactness of agricultural soil for soybean planting, and the testing mechanism is installed at the rear position inside the frame;

[0008] The testing mechanism includes a three-claw bracket and a circular cylinder. The three-claw bracket is fixedly installed on the side of the top of the frame. The circular cylinder is fixedly connected to the center of the three-claw bracket. A circular hole is opened at the bottom of the outer circular surface of the circular cylinder. A connecting pressure rod is slidably installed in the middle of the inner part of the circular cylinder. A test cone is installed at the bottom end of the connecting pressure rod. A puncture rod is hinged on the outer circular surface of the connecting pressure rod near the circular hole. An electric telescopic rod is fixedly connected to the inner wall of the circular cylinder near the top. A guide sleeve is fixedly connected to the middle of the inner cavity of the circular cylinder. The connecting pressure rod passes through the center of the guide sleeve, and the telescopic end of the electric telescopic rod is contracted to apply a downward pulling force to the connecting pressure rod through the telescopic end of the electric telescopic rod, and under the support and guidance of the circular cylinder, the connecting pressure rod is moved downward, so that the test cone can be driven downward by the connecting pressure rod, and the tip of the test cone is facing downward, so that the tip of the test cone contacts with the soybean planting agricultural soil. Under the continuous pressure of the connecting pressure rod, the tip of the test cone is inserted into the soil, so that the compaction of the soybean planting agricultural soil can be tested.

[0009] Preferably, the central axis in the middle of the connecting pressure rod coincides with the central axis in the middle of the circular cylinder, the telescopic end of the electric telescopic rod is fixedly connected to the outer circular surface of the connecting pressure rod, there are two electric telescopic rods, and the two electric telescopic rods are symmetrically installed along the connecting pressure rod.

[0010] As the connecting pressure rod moves downward, the guide sleeve can guide the connecting pressure rod, and the puncture rod will be pushed downward by the connecting pressure rod, so that the puncture rod passes through the center of the circular hole and moves downward. The tip of the puncture rod is inserted into the soil, and the connecting pressure rod can be supported by the puncture rod. The four puncture rods are evenly distributed on the outer circular surface of the connecting pressure rod, which can increase the support points and make the connecting pressure rod less likely to bend and deform. Therefore, when the test cone is tested on soil with higher hardness, the test cone will not be skewed or offset, and the soil can be tested accurately.

[0011] Preferably, the tip of the test cone and the tip of the puncture rod are both facing downward, and the puncture rod passes through the center of the circular hole. There are four puncture rods, and the four puncture rods are evenly distributed on the outer cylindrical surface of the connecting pressure rod, and contact the soil surface through the surface of the disc. As the frame moves as a whole, the disc drives the elastic strip to roll. When the elastic strip contacts the stone, the elastic strip and the stone squeeze each other, and through the elastic force of the elastic strip itself, the stone squeezes two adjacent elastic strips apart, so that the stone enters the woven cage formed by the elastic strip, and the stone can be collected, thereby reducing the impact of the stone on the test cone detection.

[0012] Preferably, the pretreatment mechanism includes a linear drive, the bottom of which is fixedly mounted to the side of the inside of the frame by screws, the output end of the linear drive is fixedly mounted with a connecting slider, the surface of the connecting slider and the side away from the linear drive is fixedly connected with a right-angle connecting rod, the middle of the surface of the right-angle connecting rod is fixedly connected with a reset spring, and the bottom end of the right-angle connecting rod is installed with a debris removal component.

[0013] Preferably, the linear drive is installed vertically, there are two linear drives, and the two linear drives are installed symmetrically along the central axis in the middle of the frame, and the reset spring is arc-shaped.

[0014] Preferably, the debris removing component includes a slide rail, the interior of the slide rail is slidably installed with the bottom end of the right-angle connecting rod, and a roller is slidably installed on the end of the slide rail surface, and the bottom of the slide rail is fixedly connected to a cross beam, and the bottom of the cross beam is fixedly connected to an arc-shaped elastic claw, and both ends of the bottom of the beam are slidably installed with a disc through a bent plate, and the edge of the disc surface is fixedly connected with an elastic strip, and the output end of the linear drive drives the connecting slider to move, and under the connection of the right-angle connecting rod, the right-angle connecting rod is passively driven to move downward as a whole, and the bottom end of the arc-shaped elastic claw contacts the soil surface, and the rolling of the wheel is used to drive the frame as a whole to move, and the movement of the arc-shaped elastic claw can be used to scrape the stones, weeds and dead leaves on the soil surface, so that the stones, weeds and dead leaves are separated from the soil, and the debris is pre-processed.

[0015] The spiral shape of the elastic strip facilitates the contact between the elastic strip and the uneven surface, helps the elastic strip and the disc to roll, and makes the elastic strip always in a rolling state. The spiral elastic strip pushes the stone. The elastic strip with a spiral structure can generate a lateral suction force on the stone through the inclination angle of the spiral pattern, thereby reducing the situation where the stone slips at the edge of the elastic strip and is missed.

[0016] Preferably, the arc-shaped elastic claws are evenly distributed at the bottom of the crossbeam, the elastic strips are spiral-shaped, and the elastic strips are evenly distributed at the edge of the disc surface. The roller is toggled by the toggle piece, so that the slide rail drives the arc-shaped elastic claws and the elastic strips to move away from the toggle piece, and the reset spring is elastically deformed by the pressure.

[0017] As the wheel drives the toggle plate to rotate continuously, the toggle plate is separated from the roller, the toggle force applied to the roller disappears, and under the elastic force of the reset spring, the slide rail drives the arc-shaped elastic claw and the elastic strip to move in the opposite direction for reset. In this way, the arc-shaped elastic claw and the elastic strip move back and forth, and debris can be cleaned multiple times without residue.

[0018] Preferably, a heating mechanism is installed in the middle of the interior of the frame, and the heating mechanism includes a heater and an annular shell. The heater is fixedly installed in the middle of the top of the frame, and the annular shell is fixedly installed at the bottom of the inner cavity of the frame, and the circular cylinder passes through the center of the annular shell, and the top of the annular shell is fixedly connected to the outer circular surface of the circular cylinder. A suction fan is fixedly installed on the side of the surface of the heater, and a bent air pipe is installed between the surface of the heater and the edge of the top of the annular shell. An exhaust pipe is fixedly connected to the bottom of the annular shell, and a guide plate is fixedly connected to the middle of the exhaust pipe. The circular cylinder passes through the center of the annular shell, so that the annular shell supports the bottom of the surface of the circular cylinder, so that the circular cylinder as a whole is more stable and less likely to tilt.

[0019] Preferably, the center of the annular shell coincides with the central axis of the middle of the circular cylinder, there are two bent air pipes, and the two bent air pipes are symmetrically installed along the heater, the air inlet of the suction fan is connected to the heater, and the air outlet of the suction fan, the circular cylinder and the annular shell are connected, the heater is used to heat the air, and the hot air heated by the heater is sucked out by the suction fan, and under the transportation of the bent air pipe, the hot air enters the interior of the annular shell, and under the action of gas pressure, the hot air enters the interior of the exhaust pipe and is discharged downward to heat and dry the soil, and dry the moist soil so as to perform a compaction test on the dried soil.

[0020] Preferably, the exhaust pipes are evenly distributed at the bottom of the annular shell, and the guide vanes are spiral-shaped. As the hot air is discharged from the inside of the exhaust pipe, the spiral guide vanes are used to discharge the swirling hot air outward. The eddy current field formed by the rotation can make the hot air contact the soil at multiple angles, thereby increasing the collision frequency and contact time between the hot air and soil particles, improving the heat transfer efficiency, and effectively drying the soil.

[0021] The present invention provides a soil compaction testing device for soybean planting. It has the following beneficial effects:

[0022] 1. The soil compaction testing equipment for soybean planting agriculture applies a downward pulling force to the connecting pressure rod through the telescopic end of the electric telescopic rod, so that the connecting pressure rod moves downward, and the test cone is driven downward by the connecting pressure rod. The tip of the test cone is pointed downward, so that the tip of the test cone contacts the soybean planting agricultural soil. Under the continuous pressure of the connecting pressure rod, the tip of the test cone is inserted into the soil, so that the soil compaction of soybean planting agriculture can be tested.

[0023] 2. The soil compaction testing equipment for soybean planting agriculture uses a guide sleeve to guide the connecting pressure rod, and the puncture rod will be pushed downward by the connecting pressure rod. The tip of the puncture rod is inserted into the soil, and the connecting pressure rod can be supported by the puncture rod. The four puncture rods are evenly distributed on the outer circular surface of the connecting pressure rod, which can increase the support points and make the connecting pressure rod less likely to bend and deform. Therefore, when the test cone is tested on soil with higher hardness, the test cone will not be skewed or offset, and the soil can be tested accurately.

[0024] 3. The soil compaction testing equipment for soybean planting agriculture uses the output end of the linear drive to drive the connecting slider to move, and under the connection of the right-angle connecting rod, the right-angle connecting rod is passively driven to move downward as a whole, and the bottom end of the arc-shaped elastic claw contacts the soil surface. The rolling of the wheel is used to drive the entire frame to move, and the movement of the arc-shaped elastic claw can be used to scrape stones, weeds and dead leaves on the soil surface, so that the stones, weeds and dead leaves are separated from the soil, and the debris is pre-processed.

[0025] 4. This soil compaction testing equipment for soybean planting agriculture, as the frame moves as a whole, causes the disc to drive the elastic strip to roll. When the elastic strip contacts the stone, the elastic strip and the stone squeeze each other, and through the elastic force of the elastic strip itself, the stone pushes two adjacent elastic strips apart, allowing the stone to enter the woven cage formed by the elastic strip, so that the stone can be collected, thereby reducing the impact of the stone on the test cone detection.

[0026] 5. The soil compaction testing equipment for soybean planting uses a spiral elastic strip to facilitate the contact between the elastic strip and the uneven surface, which helps the elastic strip and the disc to roll, so that the elastic strip is always in a rolling state, and the spiral elastic strip pushes the stones. The elastic strip with a spiral structure can generate lateral suction force on the stones through the inclination angle of the spiral texture, reducing the situation where the stones slip at the edge of the elastic strip and are missed.

[0027] 6. The soil compaction testing equipment for soybean planting agriculture uses a toggle plate to toggle the roller, so that the slide rail drives the arc-shaped elastic claw and the elastic strip to move away from the toggle plate. As the toggle force on the roller disappears, and under the elastic force of the reset spring, the slide rail drives the arc-shaped elastic claw and the elastic strip to move in the opposite direction for reset. In this way, the reciprocating movement of the arc-shaped elastic claw and the elastic strip can clean up debris multiple times, and it is not easy to leave residue.

[0028] 7. The soil compaction testing equipment for soybean planting agriculture uses a circular cylinder to pass through the center of the annular shell, so that the annular shell supports the bottom of the circular cylinder surface, thereby making the circular cylinder as a whole more stable and less likely to tilt.

[0029] 8. This soil compaction testing equipment for soybean planting agriculture, when encountering moist soil, uses a heater to heat the air, and uses a suction fan to suck out the hot air heated by the heater. The hot air is transported by the bent air pipe and enters the interior of the annular shell. Under the action of gas pressure, the hot air enters the interior of the exhaust pipe and is discharged downward to heat and dry the soil, and dry the moist soil so that the compaction of the dried soil can be tested.

[0030] 9. This soil compaction testing equipment for soybean planting agriculture, as the hot air is discharged from the inside of the exhaust pipe, uses the spiral diversion of the guide plate to discharge the swirling hot air outward. The eddy current field formed by the rotation can make the hot air contact with the soil at multiple angles, increasing the collision frequency and contact time between the hot air and soil particles, improving the heat transfer efficiency, and effectively drying the soil.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0045] A soil compaction testing device for soybean planting agriculture, comprising:

[0046] A frame 1, and a wheel 2 mounted at the bottom of the frame 1, a toggle plate 3 fixedly connected to the side of the surface of the wheel 2, and a pre-treatment mechanism 4 installed on the side of the interior of the frame 1;

[0047] A testing mechanism 5 is used to detect the compactness of the soil in soybean planting agriculture. The testing mechanism 5 is installed at the rear position inside the frame 1;

[0048] Among them, the testing mechanism 5 includes a three-claw bracket 51 and a circular cylinder 52. The three-claw bracket 51 is fixedly installed on the side of the top of the frame 1, and the circular cylinder 52 is fixedly connected to the center of the three-claw bracket 51. A circular hole 53 is opened at the bottom of the outer circular surface of the circular cylinder 52. A connecting pressure rod 54 is slidably installed in the middle of the inner part of the circular cylinder 52. A test cone 55 is installed at the bottom end of the connecting pressure rod 54. A puncture rod 56 is hinged on the outer circular surface of the connecting pressure rod 54 and near the circular hole 53. An electric telescopic rod 57 is fixedly connected to the inner wall of the circular cylinder 52 and near the top. A guide sleeve 58 is fixedly connected to the middle of the inner cavity of the circular cylinder 52. Passing through the center of the guide sleeve 58, the staff turns on the electric telescopic rod 57 to work, and uses the contraction of the telescopic end of the electric telescopic rod 57 to apply a downward pulling force to the connecting pressure rod 54 through the telescopic end of the electric telescopic rod 57. Under the support and guidance of the circular cylinder 52, the connecting pressure rod 54 is moved downward, so that the test cone 55 can be driven downward by the connecting pressure rod 54, and combined with the tip of the test cone 55 facing downward, the tip of the test cone 55 is brought into contact with the soybean planting agricultural soil. Under the continuous pressure of the connecting pressure rod 54, the tip of the test cone 55 is inserted into the soil to test the soil compaction.

[0049] The central axis of the middle of the connecting pressure rod 54 coincides with the central axis of the middle of the circular cylinder 52, and the telescopic end of the electric telescopic rod 57 is fixedly connected to the outer cylindrical surface of the connecting pressure rod 54. There are two electric telescopic rods 57, and the two electric telescopic rods 57 are symmetrically installed along the connecting pressure rod 54. As the connecting pressure rod 54 moves downward and passes through the center of the guide sleeve 58 in combination with the connecting pressure rod 54, the guide sleeve 58 can guide the connecting pressure rod 54, and the puncture rod 56 will be pushed downward by the connecting pressure rod 54, so that the puncture rod 56 passes through the center of the circular hole 53 and moves downward. The tip of the puncture rod 56 is inserted into the soil, and the connecting pressure rod 54 can be supported by the puncture rod 56. The four puncture rods 56 are evenly distributed on the outer cylindrical surface of the connecting pressure rod 54, which can increase the support points, making the connecting pressure rod 54 not easy to bend and deform, so that when the test cone 55 is tested on soil with higher hardness, the test cone 55 will not be skewed or offset, and the soil can be accurately tested.

[0050] The tip of the test cone 55 and the tip of the puncture rod 56 are both facing downwards. The puncture rod 56 passes through the center of the circular hole 53. There are four puncture rods 56, and the four puncture rods 56 are evenly distributed on the outer circumferential surface of the connecting pressure rod 54.

[0051] The second embodiment, based on the first embodiment, see Figures 1 to 8 As shown:

[0052] The pretreatment mechanism 4 includes a linear drive 41, the bottom of which is fixedly installed on the side of the inside of the frame 1 by screws, and a connecting slider 42 is fixedly installed on the output end of the linear drive 41. A right-angle connecting rod 43 is fixedly connected to the surface of the connecting slider 42 and the side away from the linear drive 41. A reset spring 44 is fixedly connected to the middle of the surface of the right-angle connecting rod 43, and a debris removal component 45 is installed on the bottom end of the right-angle connecting rod 43.

[0053] The linear drive 41 is installed vertically. There are two linear drives 41 , and the two linear drives 41 are installed symmetrically along the central axis in the middle of the frame 1 . The reset spring 44 is arc-shaped.

[0054] The debris removal component 45 includes a slide rail 451, the interior of the slide rail 451 is slidably installed with the bottom end of the right-angle connecting rod 43, and a roller 452 is routably installed on the end of the surface of the slide rail 451. The bottom of the slide rail 451 is fixedly connected to a crossbeam 453, and the bottom of the crossbeam 453 is fixedly connected to an arc-shaped elastic claw 454. Both ends of the bottom of the crossbeam 453 are routably installed with a disc 455 through a bent plate, and the edge of the surface of the disc 455 is fixedly connected to an elastic strip 456. The staff starts the linear drive 41 to work, and uses the output end of the linear drive 41 to drive the connecting slider 42 to move, and under the connection of the right-angle connecting rod 43, the right-angle connecting rod 43 is passively driven to move downward as a whole, and the bottom end of the arc-shaped elastic claw 454 contacts the soil surface, and the rolling of the wheel 2 is used to drive the frame 1 to move as a whole, so that the movement of the arc-shaped elastic claw 454 can be used to scrape stones, weeds and dead leaves on the soil surface.

[0055] The arc-shaped elastic claws 454 are evenly distributed at the bottom of the crossbeam 453, and the elastic strips 456 are spiral-shaped. The elastic strips 456 are evenly distributed at the edge of the surface of the disc 455. The surface of the disc 455 contacts the soil surface. As the frame 1 moves as a whole, the disc 455 drives the elastic strips 456 to roll. When the elastic strips 456 contact the stones, the elastic strips 456 and the stones squeeze each other, and through the elastic force of the elastic strips 456 themselves, the stones squeeze two adjacent elastic strips 456 apart, so that the stones enter the woven cage formed by the elastic strips 456 and are collected.

[0056] As the wheel 2 rolls, the wheel 2 drives the toggle piece 3 to rotate in a circle, and the toggle piece 3 contacts the roller 452, so that the roller 452 is subjected to the toggle force of the toggle piece 3, and under the support of the right-angle connecting rod 43, the slide rail 451 drives the arc-shaped elastic claw 454 and the elastic strip 456 to move in the direction away from the toggle piece 3, and the reset spring piece 44 is elastically deformed by the pressure. As the wheel 2 drives the toggle piece 3 to continue to rotate, the toggle piece 3 is separated from the roller 452, and the toggle force applied to the roller 452 disappears. Under the elastic force of the reset spring piece 44, the slide rail 451 drives the arc-shaped elastic claw 454 and the elastic strip 456 to move in the opposite direction for reset. In this way, the arc-shaped elastic claw 454 and the elastic strip 456 move back and forth, and debris can be cleaned multiple times.

[0057] The third embodiment, based on the first and second embodiments, see Figures 1 to 11 As shown:

[0058] A heating mechanism 6 is installed in the middle of the interior of the frame 1. The heating mechanism 6 includes a heater 61 and an annular shell 62. The heater 61 is fixedly installed in the middle of the top of the frame 1, and the annular shell 62 is fixedly installed at the bottom of the inner cavity of the frame 1. The circular cylinder 52 passes through the center of the annular shell 62, and the top of the annular shell 62 is fixedly connected to the outer circular surface of the circular cylinder 52. A suction fan 63 is fixedly installed on the side of the surface of the heater 61, and a bent air pipe 64 is installed between the surface of the heater 61 and the edge of the top of the annular shell 62. An exhaust pipe 65 is fixedly connected to the bottom of the annular shell 62, and a guide plate 66 is fixedly connected to the middle of the exhaust pipe 65. The circular cylinder 52 passes through the center of the annular shell 62, so that the annular shell 62 supports the bottom of the surface of the circular cylinder 52, and the circular cylinder 52 is more stable as a whole.

[0059] The center of the annular shell 62 coincides with the central axis of the middle of the circular cylinder 52. There are two bent air pipes 64, and the two bent air pipes 64 are symmetrically installed along the heater 61. The air inlet of the suction fan 63 is connected to the heater 61, and the air outlet of the suction fan 63, the circular cylinder 52 and the annular shell 62 are connected. When encountering moist soil, the staff turns on the heater 61 to work, uses the heater 61 to heat the air, and sucks out the hot air heated by the heater 61 through the suction fan 63. Under the transportation of the bent air pipe 64, the hot air enters the interior of the annular shell 62. Under the action of gas pressure, the hot air enters the interior of the exhaust pipe 65 and is discharged downward to heat and dry the soil, thereby drying the moist soil.

[0060] The exhaust pipes 65 are evenly distributed at the bottom of the annular shell 62, and the guide vanes 66 are spiral-shaped.

[0061] When in use, in the initial state, the entire impurity removal component 45 is lifted by the output end of the linear drive 41, and the entire frame 1 is moved to a designated position in the agricultural soybean planting area through the rolling of the wheels 2;

[0062] At this time, the staff starts the linear drive 41 to work, and uses the output end of the linear drive 41 to drive the connecting slider 42 to move. Under the connection of the right-angle connecting rod 43, the right-angle connecting rod 43 is passively driven to move downward as a whole. The bottom end of the arc-shaped elastic claw 454 contacts the soil surface, and the frame 1 is driven to move as a whole by the rolling of the wheel 2. The movement of the arc-shaped elastic claw 454 can be used to scrape stones, weeds and dead leaves on the soil surface.

[0063] The surface of the disc 455 contacts the soil surface. As the vehicle frame 1 moves as a whole, the disc 455 drives the elastic strips 456 to roll. When the elastic strips 456 contact the stones, the elastic strips 456 and the stones squeeze each other. Due to the elastic force of the elastic strips 456 themselves, the stones push two adjacent elastic strips 456 apart, allowing the stones to enter the woven cage formed by the elastic strips 456 and collect the stones.

[0064] At the same time, as the wheel 2 rolls, the wheel 2 drives the toggle piece 3 to rotate in a circle, and the toggle piece 3 contacts the roller 452, so that the roller 452 is subjected to the toggle force of the toggle piece 3, and under the support of the right-angle connecting rod 43, the slide rail 451 drives the arc-shaped elastic claw 454 and the elastic strip 456 to move in the direction away from the toggle piece 3, and the reset spring piece 44 is elastically deformed by the pressure. As the wheel 2 drives the toggle piece 3 to continue to rotate, the toggle piece 3 is separated from the roller 452, and the toggle force on the roller 452 disappears. Under the elastic action of the reset spring piece 44, the slide rail 451 drives the arc-shaped elastic claw 454 and the elastic strip 456 to move in the opposite direction to reset. In this way, the arc-shaped elastic claw 454 and the elastic strip 456 move back and forth, and debris can be cleaned multiple times;

[0065] The circular cylinder 52 is passed through the center of the annular shell 62 so that the annular shell 62 supports the bottom of the surface of the circular cylinder 52, and the circular cylinder 52 as a whole is more stable. The staff turns on the electric telescopic rod 57 to work, and uses the contraction of the telescopic end of the electric telescopic rod 57 to apply a downward pulling force to the connecting pressure rod 54 through the telescopic end of the electric telescopic rod 57. Under the support and guidance of the circular cylinder 52, the connecting pressure rod 54 is moved downward, and the test cone 55 is driven downward by the connecting pressure rod 54. In combination with the tip of the test cone 55 facing downward, the tip of the test cone 55 is brought into contact with the soybean planting agricultural soil. Under the continuous pressure of the connecting pressure rod 54, the tip of the test cone 55 is inserted into the soil to test the soil compaction.

[0066] As the connecting pressure rod 54 moves downward and passes through the center of the guide sleeve 58 in combination with the connecting pressure rod 54, the guide sleeve 58 can guide the connecting pressure rod 54, and the puncture rod 56 will be pushed downward by the connecting pressure rod 54, so that the puncture rod 56 passes through the center of the circular hole 53 and moves downward. The tip of the puncture rod 56 is inserted into the soil, and the connecting pressure rod 54 can be supported by the puncture rod 56. The four puncture rods 56 are evenly distributed on the outer circular surface of the connecting pressure rod 54, which can increase the support points and make the connecting pressure rod 54 less likely to bend and deform. Therefore, when the test cone 55 is used for soil with higher hardness, the test cone 55 will not be skewed or offset, and the soil can be accurately tested.

[0067] Moreover, when encountering moist soil, the staff turns on the heater 61 to work, uses the heater 61 to heat the air, and sucks out the hot air heated by the heater 61 through the suction fan 63. The hot air is transported by the bent air pipe 64 and enters the interior of the annular shell 62. Under the action of gas pressure, the hot air enters the interior of the exhaust pipe 65 and is discharged downward to heat and dry the soil, and dry the moist soil so that the soil can be tested for compactness later.
