[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-4 A soil hardness detector shown includes a hardness detector body 1 and an equipment bracket 4, a detection assembly 2 arranged outside the equipment bracket 4, and a scraper rod assembly 3 outside the equipment bracket 4;

[0026] The detection assembly 2 includes a tripod 21 arranged at both ends of the equipment support 4, a descending block 22 arranged at one side of the equipment support 4, and a descending screw rod 23 arranged at one side of the equipment support 4;

[0027] A track mounting block 24 is fixed to one side of the equipment bracket 4, two sets of sliding rods 25 are fixed to the surface of the track mounting block 24, the descending block 22 is slidably connected to the outer surface of the sliding rod 25, and the hardness tester body 1 is fixed to one side of the descending block 22;

[0028] Bearing rods 26 are fixed at both ends of the bottom of the equipment bracket 4, one end of the tripod 21 is rotatably connected to the outer surface of the bearing rod 26 through a bearing member, a spring is arranged between the tripod 21 and the bearing rod 26, and blocks 27 are fixed at both ends of the equipment bracket 4, and a trigger switch is fixed at the bottom of a group of blocks 27.

[0029] In this implementation scheme: the operator only needs to lower the device, and after the device completes the fixed state, the device controls the hardness tester body to descend to complete the soil hardness test, and the test result is more accurate.

[0030] A screw bearing seat 28 is fixed on the surface of the track mounting block 24, and the descending screw 23 is rotatably connected to the central axis of the screw bearing seat 28. A threaded groove matching the descending screw 23 is opened on the surface of the descending block 22, and the descending screw 23 is threadedly connected to the threaded groove of the descending block 22. A descending motor 29 is fixed on the top of the track mounting block 24, and the output end of the descending motor 29 is connected to one end of the descending screw 23.

[0031] The descending motor 29 drives the descending screw rod 23 to rotate along the track of the screw rod bearing seat 28, and the descending block 22 threadedly connected with the descending screw rod 23 descends along the track of the sliding rod 25. An elliptical block 201 is fixed to the other end of the tripod 21. The elliptical block 201 is used to facilitate contact with uneven ground.

[0032] A display screen operation panel 202 is fixed to one side of the equipment bracket 4.

[0033] The trigger position of the descending motor 29 is the position of the trigger switch, and the stop position of the descending motor 29 is until the weight inside the hardness tester body moves to the limit position, until the weight of the hardness tester body moves to the trigger block position, at which time the descending motor 29 will also stop moving, the weight rebounds, and the hardness tester records the rebound value and feeds the recorded value back to the display operation panel 202. In this scheme, it is the stop position of the descending motor 29 of the weight-type hardness tester. If it is a sensor-type tester, the descending motor 29 moves into the soil, and the sensor tester can continuously detect the force fed back by the soil and record the entire process.

[0034] A vertical pole 203 is fixed on the top of the equipment support 4, and handles 204 are fixed on both sides of the outer surface of the vertical pole 203. The handles 204 are used for operators to operate the device.

[0035] Sliding blocks 31 are fixed on both sides of the top of the track mounting block 24. The inner wall of the sliding block 31 is slidably connected with a sliding rod 32. The two sets of sliding rods 32 are axially symmetrically arranged. An arc block 33 is fixed at one end of the sliding rod 32, and a brush is fixed on the inner wall of the arc block 33.

[0036] When the device is not in daily use, the firing pin position can be cleaned.

[0037] The inner wall of one group of sliding blocks 31 is rotatably connected to a gear 34, the inner wall of one group of sliding rods 32 is fixed with a first rack 35, the first rack 35 is meshingly connected to the gear 34, the outer side of another group of sliding rods 32 is fixed with an extension rod 36, the inner wall of the extension rod 36 is fixed with a second rack 37, the second rack 37 is meshingly connected to the gear 34.

[0038] By pushing one group of slide rods 32, one group of slide rods 32 drives the gear 34 to rotate through the extension rod 36, and the other group of slide rods 32 also rotates inward through the second rack 37, so that the two groups of brushes are close to each other. By turning on the cleaning mode, the lowering motor 29 drives the hardness tester body to reciprocate, so that the brush cleans the striker of the tester body.

[0039] When the soil hardness needs to be tested, the operator holds the handle 204 to place the equipment bracket 4 at the required testing position. The two sets of tripods 21 are initially tilted. When the operator presses down, the elliptical block 201 contacts the soil, and the two sets of tripods 21 rotate along the trajectory of the bearing rod 26 until the tripod 21 contacts the stopper 27. A trigger switch is provided below the stopper 27 to trigger the driving of the descending motor 29. The descending motor 29 drives the descending screw rod 23 to rotate along the trajectory of the screw rod bearing seat 28. The descending block 22 threadedly connected to the descending screw rod 23 descends along the trajectory of the sliding rod 25 until the striker of the hardness tester body contacts the soil until the inside of the hardness tester body The weight moves to the extreme position until the weight of the hardness tester body moves to the trigger block position. At this time, the descending motor 29 will also stop moving, and the weight rebounds. The hardness tester will record the rebound value and feed the recorded value back to the display operation panel 202. During daily non-use, by pushing one group of slide bars 32, one group of slide bars 32 drives the gear 34 to rotate through the extension rod 36, and the other group of slide bars 32 will also rotate inward through the second rack 37, so that the two groups of brushes are close to each other. By turning on the cleaning mode, the descending motor 29 drives the hardness tester body to reciprocate, so that the brush cleans the striker of the tester body.

[0040] In summary, through the setting of the detection component 2, the operator only needs to lower the device, and after the device completes the fixed state, the device controls the hardness tester body to descend to complete the soil hardness test, and the test result is more accurate. Through the setting of the scraper rod component 3, the device can clean the impact pin position when it is not in daily use.
