[0002] A soil hardness tester is an instrument specifically used to measure soil hardness. It is usually small, highly accurate, and easy to operate, and is designed to be portable for use in field soil surveys. Existing small and medium-sized soil hardness testers require operators to use the device to manually press the soil to be tested when sampling and testing the soil. This method of operation requires operators to spend a lot of effort to press the device when testing harder soil. If human power cannot press through the hard soil on the surface, the hardness of the lower soil cannot be tested, resulting in a limited detection range for the entire device. Therefore, it is of great significance to expand the detection range of the soil hardness tester. Utility Model Content
[0003] In order to overcome the shortcoming that the detection range of the soil hardness detector for environmental detection is limited, the purpose of the utility model is to provide a soil hardness detector for environmental detection that can expand the detection range.

The detection component includes a servo motor, a screw rod, a limit rod, a movable block and a detection rod. A servo motor is installed on the left side of the bracket, and the left side of the bracket is rotatably connected to the screw rod. The upper end of the screw rod is connected to the output shaft of the servo motor through a coupling, and the lower end of the screw rod is rotatably connected to the bracket. A limit rod is provided on the right side of the bracket, and the two ends of the limit rod are respectively fixedly connected to the bracket.

The front and rear sides of the bottom of the bracket are fixedly connected to the limiting plate by bolts, the front and rear sides of the bottom of the bracket are rotatably connected with a rotating shaft, and the rotating shaft is located below the limiting plate. The rotating shafts on the front and rear sides are fixedly connected with fixed plates, and torsion springs are provided at both ends of the rotating shaft, one end of the torsion spring is fixedly connected to the fixed plate, and the other end of the torsion spring is fixedly connected to the bracket.

It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning.

[0018] Example 1
[0019] A soil hardness tester for environmental testing, such as Figure 1-3 As shown, it includes a bracket 1, a control panel 2 and a detection component. The bracket 1 is U-shaped, and the control panel 2 is fixedly connected to the upper part of the bracket 1. The bracket 1 is provided with a detection component for expanding the detection range of the detection rod 7. The detection component includes a servo motor 3, a screw rod 4, a limit rod 5, a movable block 6 and a detection rod 7. The servo motor 3 is installed on the left side of the bracket 1. The left side of the bracket 1 is rotatably connected with the screw rod 4. The upper end of the screw rod 4 is connected to the output shaft of the servo motor 3 through a coupling, and the lower end of the screw rod 4 is rotatably connected to the bracket 1. A limit rod 5 is provided on the right side of the bracket 1, and the two ends of the limit rod 5 are respectively fixedly connected to the bracket 1. A movable block 6 is provided between the screw rod 4 and the limit rod 5. The right side of the movable block 6 is slidably connected to the limit rod 5. The left side of the movable block 6 is threadedly matched with the screw rod 4, and the middle part of the movable block 6 is fixedly connected with the detection rod 7.
[0020] The staff first places the device on the surface of the soil to be tested, operates the control panel 2 to test the hardness of the soil, then starts the servo motor 3, and the output shaft of the servo motor 3 starts to rotate counterclockwise. At this time, the screw rod 4 connected to the output shaft of the servo motor 3 rotates with the servo motor 3, and the screw rod 4 and the movable block 6 are threaded. At this time, the screw rod 4 drives the movable block 6 to move downward. During the descent of the movable block 6, the limit rod 5 located on the right side of the bracket 1 limits the movable block 6. At this time, the detection rod 7 fixed on the movable block 6 follows the movable block 6 to descend, and the detection rod 7 detects the hardness of the soil during the descent. At this time, if the surface layer of the soil to be tested is harder, the operator does not need to manually insert the detection rod 7 into the harder soil, which reduces the difficulty of soil hardness detection for the staff and expands the detection range of the soil hardness detector. After completing the detection, the operator starts the servo motor 3 again. At this time, the servo motor 3 rotates clockwise, and the output shaft of the servo motor 3 drives the screw rod 4 to rotate clockwise. The screw rod 4 drives the movable block 6 to move upward. At the same time, the detection rod 7 fixedly connected to the movable block 6 rises with the movable block 6. After the detection rod 7 rises to the initial position, the servo motor 3 is turned off. At this time, the soil hardness detection of the area is completed.
[0021] It also includes a supporting assembly, which includes a limiting plate 8, a rotating shaft 9, a torsion spring 10 and a fixed plate 11. The front and rear sides of the bottom of the bracket 1 are fixedly connected to the limiting plate 8 by bolts. The front and rear sides of the bottom of the bracket 1 are rotatably connected with a rotating shaft 9, and the rotating shaft 9 is located below the limiting plate 8. The rotating shafts 9 on the front and rear sides are fixedly connected with fixed plates 11. Torsion springs 10 are provided at both ends of the rotating shaft 9. One end of the torsion spring 10 is fixedly connected to the fixed plate 11, and the other end of the torsion spring 10 is fixedly connected to the bracket 1.
[0022] When the soil detector completes the detection, the operator can open the fixed plates 11 on the left and right sides of the bracket 1 and place the device flat on the ground. The limit plates 8 fixed on the left and right sides of the lower part of the bracket 1 can limit the opening angle of the fixed plates 11 to prevent the fixed plates 11 from opening at too large an angle and affecting the stability of the entire device. During the horizontal opening of the fixed plates 11, the fixed plates 11 drive the rotating shaft 9 to rotate. At this time, the torsion spring 10 is compressed. When the device is placed flat on the ground, the weight of the entire device can overcome the rebound force of the torsion spring 10, ensuring that the fixed plates 11 will not be retracted due to the action of the torsion spring 10, thereby achieving the effect of being stably placed when the device is not needed, thereby improving the convenience of placing the device. When the device needs to be used, the device can be directly picked up. At this time, the torsion spring 10 is relaxed and the fixed plates 11 are retracted.
[0023] The bracket 1 further comprises a handle 12 , which is fixedly connected to the top of the bracket 1 , and an anti-slip pad 13 is fixedly connected to the handle 12 .
[0024] When the staff needs to carry the device, a handle 12 is provided on the top of the bracket 1 to increase the portability of the device. In order to prevent the device from slipping out of the hand due to insufficient friction during the process of carrying, an anti-slip pad 13 is added to the handle 12 to increase the anti-slip effect during the process of carrying the device.
[0025] The bracket 1 further includes two protective plates 14 , which are respectively fixedly connected to the front side and the rear side of the bracket 1 .
[0026] The device is generally used outdoors, and the detection rod 7 is a vulnerable part in the entire device. In order to increase the protection of the detection rod 7, protective plates 14 are added to the front and rear sides of the bracket 1 to protect the detection rod 7 and increase the service life of the device.
[0027] The device further comprises a scale observation window 15 , which is located on the rear protection plate 14 .
[0028] In order to better observe the state of the detection rod 7 during use, a scale observation window 15 is added to the protective plate 14, so that the operator can observe the detection rod 7 in time during the use of the device, thereby increasing the controllability of the entire device.
[0029] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
