Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a multifunctional automatic penetrometer for soil detection. Background Technique

[0002] A soil penetrometer is a device for measuring soil permeability or soil water conductivity. It is widely used in the fields of agriculture and environmental science to evaluate the water flow characteristics of soil. By using a soil penetrometer, we can determine the infiltration rate and absorption capacity of soil for water, which is of great significance for aspects such as agricultural irrigation and soil protection.

[0003] According to a disclosed multifunctional automatic penetrometer for soil detection (publication number: CN 106404630 B), it includes an injection system, a model system, and a data acquisition and processing system; the injection system includes a liquid storage container, a pressure regulating valve, a control valve, and a pressure relief valve; a partition plug is arranged in the middle of the liquid storage container to divide the liquid storage container into a gas chamber and a liquid chamber, and an air inlet is arranged on the gas chamber; a liquid outlet is arranged on the liquid chamber, and a permeation liquid for the soil sample in the model system is placed in the liquid chamber. The liquid outlet of the liquid chamber is connected to the soil sample holder of the model system through a liquid pipe; the pressure regulating valve is connected to a gas source, and the gas source is divided into three output routes after passing through the pressure regulating valve; the first output route of the gas source is connected to the air inlet on the cylinder of the model system. In the above application, a multifunctional automatic penetrometer for soil detection, temperature sensors, pressure sensors and other devices are used to detect the soil. However, when it is necessary to move to different areas for detection, it may be necessary to disassemble and then reinstall, which is very inconvenient. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a multifunctional automatic penetrometer for soil detection, which solves the problems raised in the above background technique. To achieve the above purposes, the utility model is realized through the following technical solutions: A multifunctional automatic penetrometer for soil detection, including a penetrometer body, a support frame is fixedly connected to the side of the penetrometer body, a base is fixedly connected to the bottom end of the support frame, a moving push handle mechanism is slidably connected inside the base, and universal wheels are fixedly connected to the bottom end of the base; the moving push handle mechanism includes a push handle, a support rod is fixedly connected to the side of the push handle, a bolt is threadedly connected to the side of the support rod, a connecting plate is threadedly connected to the side of the bolt, a slider is fixedly connected to the side of the connecting plate, a first chute is opened inside the base, a first spring is fixedly connected inside the slider, a limiting rod is fixedly connected to the side of the first spring, a card slot is opened inside the base, a push rod is slidably connected inside the card slot, a second spring is fixedly connected to the side of the push rod, a connecting rod is fixedly connected to the side of the push rod, a second chute is opened inside the base, and a push block is fixedly connected to the side of the connecting rod.

[0005] Preferably, a limiting stop rod is slidably connected inside the base. The bottom end of the limiting stop rod is fixedly connected with a brake plate. The top end of the brake plate is fixedly connected with a third spring. The bottom end of the brake plate is fixedly connected with a rubber pad.

[0006] Preferably, a protective frame is hinged to the top end of the base. A support column is fixedly connected to the side surface of the protective frame. A support pad is fixedly connected to the side surface of the support column. A handle is fixedly connected to the side surface of the protective frame. A buckle is fixedly connected to the top end of the protective frame.

[0007] Preferably, the slider is slidably connected to the inside of the first chute, and the other connecting rod is slidably connected to the inside of the second chute. One side of the second spring is fixedly connected to the side surface of the slider, and the other side is fixedly connected to the inner side surface of the card slot.

[0008] Preferably, the part of the limiting stop rod inside the first chute has an inclined surface structure. When the slider contacts it, it will limit its downward movement, and finally make the rubber pad contact the ground.

[0009] Preferably, there are two groups of the protective frame assemblies, which are distributed on both sides of the top end of the base with the midline of the base as the axis of symmetry. The outer surface of the support pad is made of rubber material, which can provide a large frictional resistance after contacting the ground, making the device more stable during operation.

[0010] The utility model provides a multifunctional automatic penetrometer for soil detection, which has the following beneficial effects:

[0011] (1) In this application, by pulling the push handle, the support rod is driven to slide out of the first chute. When the slider reaches the farthest end, at this time, the limiting rod is affected by the elastic force of the first spring and enters the card slot, thereby completing the fixation of the slider. Subsequently, the support rod is adjusted to an appropriate angle, and by rotating the bolt clockwise, the support rod is clamped by the connecting plates on both sides to complete the fixation. Then, by pushing the push handle, the detector body is pushed to the location to be detected under the action of the universal wheels. In this way, it is not necessary to disassemble the penetrometer body to move it to the location to be detected, which is very convenient.

[0012] (2) In this application, during the sliding process of the slider in the first chute, the top end of the limiting stop rod is squeezed, causing it to move downward, thereby driving the brake plate and the rubber pad at its bottom end to contact the ground. Through the high friction of the rubber pad, the device can be more stable when it needs to work.

[0013] (3) In this application, the protective frames on both sides are rotated 90 degrees by pulling the handle, so that the support pads contact the ground. Due to the high friction between the rubber pads at the bottom of the support pads and the ground, a better stabilizing effect can be achieved when the device is working. During the process of moving the device, the protective frames can play a better protective role. Description of the Drawings

Detailed Embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Embodiment 1

[0023] Please refer to Figures 1-6 , a multifunctional automatic penetrometer for soil detection, including a penetrometer body 1, a support frame 2 is fixedly connected to the side of the penetrometer body 1, a base 3 is fixedly connected to the bottom end of the support frame 2, a moving push handle mechanism 4 is slidably connected inside the base 3, and a universal wheel 5 is fixedly connected to the bottom end of the base 3;

[0024] The mobile push handle mechanism 4 includes a push handle 41. A support rod 42 is fixedly connected to the side of the push handle 41. A bolt 43 is threadedly connected to the side of the support rod 42. A connecting plate 44 is threadedly connected to the side of the bolt 43. A slider 45 is fixedly connected to the side of the connecting plate 44. A first chute 46 is formed in the base 3. A first spring 47 is fixedly connected inside the slider 45. A limiting rod 48 is fixedly connected to the side of the first spring 47. A clamping groove 49 is formed in the base 3. A push rod 410 is slidably connected inside the clamping groove 49. A second spring 411 is fixedly connected to the side of the push rod 410. One side of the second spring 411 is fixedly connected to the side of the push rod 410, and the other side is fixedly connected to the inner side of the wall of the clamping groove 49. A connecting rod 412 is fixedly connected to the side of the push rod 410. The slider 45 is slidably connected to it inside the first chute 46. The connecting rod 412 is slidably connected to it inside a second chute 413. A second chute 413 is formed in the base 3. A push block 414 is fixedly connected to the side of the connecting rod 412. In this application, by pulling the push handle 41, the support rod 42 is pulled out of the first chute 46. When the slider 45 reaches the farthest end, at this time, the limiting rod 48 enters the clamping groove 49 under the elastic force of the first spring 47, thereby completing the fixation of the slider 45. Subsequently, the support rod 42 is adjusted to an appropriate angle. By clockwise rotating the bolt 43, the support rod 42 is clamped and fixed by the connecting plates 44 on both sides. Then, by pushing the push handle 41, under the action of the universal wheels 5, the detector body 1 is pushed to the location to be detected. In this way, it is not necessary to disassemble the penetrometer body 1, and it can be moved to the location to be detected, which is very convenient.

[0025] When this embodiment is in use, when it is necessary to change the location after the detection in this area is completed, at this time, pull the push handle 41. By pulling the push handle 41, the support rod 42 is pulled, so that the support rod 42 drives the slider 45 to slide in the first chute 46 in the direction of the push handle 41 through the connecting plate 44. As the slider 45 slides, when it reaches the farthest end, at this time, the limiting rod 48 reaches the position of the clamping groove 49. At this time, under the elastic force of the first spring 47 in the slider 45, the limiting rod 48 is pushed into the clamping groove 49 and stops moving under the action of the limiting disk at the bottom end of the limiting rod 48. At this time, the limiting rod 48 enters the clamping groove 49 to complete the fixation. At one end of the slider 45 close to the connecting plate 44, at this time, by pulling the push handle 41, the support rod 42 is adjusted to an appropriate angle. At this time, turn the bolt 43 clockwise so that the support rod 42 is fixed in the two connecting plates 44. At this time, by pushing the push handle 41 and under the action of the universal wheels 5, the base 3 drives the penetrometer body 1 fixed to the side of the support frame 2 to be moved to the location to be detected. At this time, turn the bolt 43 counterclockwise to release the fixed state of the support rod 42 and make it rotate to a horizontal state. At this time, push the push block 414 in the direction of the connecting plate 44. At this time, the push block 414 drives the connecting rod 412 to slide in the second chute 413. At the other end of the connecting rod 412, it drives the push rod 410 to move in the clamping groove 49 in the direction of the limiting rod 48 and stretch the second spring 411. Finally, the limiting rod 48 is pushed into the slider 45 to compress the first spring 47. At this time, push the support rod 42 to push the slider 45 to the farthest end of the first chute 46. Subsequently, the push block 414 and the push rod 410 are reset by the resilience of the second spring 411.

[0026] Embodiment 2

[0027] Please refer to Figure 2 , a stabilizing mechanism is added on the basis of Embodiment 1. The stabilizing mechanism includes a limiting stop rod 6. The limiting stop rod 6 is slidably connected to the base 3. A brake plate 8 is fixedly connected to the bottom end of the limiting stop rod 6. A third spring 7 is fixedly connected to the top end of the brake plate 8. One side of the third spring 7 is fixedly connected to the top end of the brake plate 8, and the other end is fixedly connected to the bottom end of the base 3. A rubber pad 9 is fixedly connected to the bottom end of the brake plate 8. The part of the limiting stop rod 6 in the first chute 46 is a bevel structure. When the slider 45 contacts it, its downward movement will be restricted, and finally the rubber pad 9 contacts the ground. In this application, during the sliding process of the slider 45 in the first chute 46, the top end of the limiting stop rod 6 is squeezed, so that it moves downward, thereby driving the brake plate 8 and the rubber pad 9 at its bottom end to contact the ground. Through the high friction of the rubber pad 9, the device can be more stable when it needs to work.

[0028] When in use, based on the first embodiment, the slider 45 is pushed and moves in the slide groove 46 in the direction away from the push handle 41. As the slider 45 moves, it will contact the part of the limit stop rod 6 in the slide groove 46. Because the part of the limit stop rod 6 in the slide groove 46 is a sloped design, when the slider 45 contacts it and moves, it will cause the limit stop rod 6 to move downward. As the limit stop rod 6 moves downward, it will drive the brake plate 8 to move downward. At the same time, as the brake plate 8 moves downward, the spring three 7 will be stretched. When the brake plate 8 reaches the bottom, the rubber pad 9 at its bottom is in contact with the ground. The friction between the rubber pad 9 and the ground can make the device more stable. Later, when the support rod 42 is pulled out of the slide groove 46, it is affected by the elastic force of the spring three 7, so that the brake plate 8 is reset, thereby pushing the device to move.

[0029] Embodiment 3

[0030] See also Figure 1 , a protective mechanism is added on the basis of the first embodiment, and the protective mechanism includes a protective frame 10, which is hinged to the top of the base 3. There are two groups of components such as the protective frame 10, which are distributed on both sides of the top of the base 3 with the midline of the base 3 as the symmetry axis. The side of the protective frame 10 is fixedly connected with a support column 11, and the side of the support column 11 is fixedly connected with a support pad 12. The outer surface of the support pad 12 is made of rubber material, which can provide greater friction resistance after contacting the ground, so that the device can be more stable when working. The side of the protective frame 10 is fixedly connected with a handle 13, and the top of the protective frame 10 is fixedly connected with a buckle 14. The present application pulls the protective frames 10 on both sides to rotate ninety degrees through the handle 13, so that the support pad 12 contacts the ground. The high friction between the rubber pad 9 at the bottom of the support pad 12 and the ground can play a better stabilizing role when the device is working, and in the process of moving the device, the protective frame 10 can play a better protective role.

[0031] During use, based on the first embodiment, when the device is moved to the location that needs to be inspected, the buckle 14 is pressed to release the fixed state, and then the handles 13 on both sides are pulled to rotate the protection frame 10. When the protection frame 10 is rotated ninety degrees, the support column 11 on its side drives the support pad 12 to contact the ground. The bottom end of the support pad 12 is made of high-friction rubber material, which can provide strong friction resistance, so that the device can be more stable when working. When it is necessary to move, the protection frames 10 on both sides are rotated and merged, and then fixed by the buckle 14 at the top, so that the device can be better protected during the movement.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
