Description

Technical Field

[0001] The utility model relates to the technical field of soil determination, and more particularly to a novel soil determination instrument. Background Art

[0002] In the field of soil testing technology, accurate and efficient acquisition of soil physical and chemical property data is crucial for agricultural management, environmental monitoring, geological exploration, and other fields. Traditional soil testers rely on operators to directly insert probes into the soil to measure key parameters such as moisture, salinity, pH, and nutrient content. This method is relatively simple and quick to operate when the soil texture is relatively loose and easily penetrated, and can meet basic soil testing needs.

[0003] However, in actual applications, especially in field working environments, soil conditions are often complex and changeable. Faced with hard soil, such as soil hardening caused by long-term drought without rain, or soil layers rich in gravel, clay, etc. that are difficult to penetrate, operators need to exert great physical force to push the probe into the soil. This not only greatly increases labor intensity and reduces work efficiency, but also easily causes varying degrees of damage to the probe, such as bending and breaking, increasing maintenance costs and measurement uncertainty. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a new soil measuring instrument. Compared with traditional soil measuring instruments, it realizes the automation of soil measurement, reduces the labor intensity of operators, and adopts a design of pre-drilling a hole in the drill rod and then safely inserting the probe, which effectively solves the problem of easy damage to the probe when operating in hard soil.

[0018] The present invention will be described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1 A new type of soil measuring instrument includes a bracket 1, a fixed plate 2 is fixed on the bracket 1, and a rotating frame 3 is rotatably connected to the fixed plate 2. A motor is fixed on the bracket 1, and the output shaft of the motor is transmission-connected to the rotation center of the rotating frame 3. Two sliding blocks 4 are fixed in an annular distribution on the rotating frame 3, and an arc-shaped groove 5 for sliding the sliding blocks 4 is provided on the fixed plate 2. Through holes are provided in the two sliding blocks 4, and a fixed rod 6 is slidably passed through the through holes. A fixed block 7 is fixed on the top of the two fixed rods 6, and a return spring 8 is fixedly abutted against the fixed block 7 and the sliding block 4. A cylinder is fixed on the top of the bracket 1, and a push block 9 is fixed on the telescopic end of the cylinder. The push block 9 is located above the rotation track of the fixed block 7, and a drill rod 10 and a probe 11 are fixedly installed on the bottom of the two fixed rods 6.

[0020] It can be understood that both the motor and the cylinder are powered by batteries, which are fixedly mounted on the bracket 1.

[0021] The cross section of the sliding block 4 is I-shaped, and a number of balls (not shown in the figure) are rotatably installed on the side of the sliding block 4 close to the fixed plate 2. A groove 12 for the balls to roll is provided on the fixed plate 2. The design of the sliding block 4 increases the contact area with the fixed plate 2 and improves the sliding stability. At the same time, the introduction of the balls reduces the friction resistance between the sliding block 4 and the fixed plate 2, making the sliding smoother.

[0022] A connecting rod 13 is fixed between the two sliding blocks 4. The connecting rod 13 further ensures the synchronization of the two sliding blocks 4 during the rotation process, thereby improving the stability and reliability of the equipment.

[0023] The fixing rod 6 and the through hole are in corresponding square structures, which can prevent the fixing rod 6 from rotating in the through hole, thereby ensuring the stability of the drill rod 10 and the probe 11 during operation.

[0024] A reducer 14 is fixedly provided on the output shaft of the motor. The output shaft of the reducer 14 is fixedly connected to the rotating frame 3, which can better control the rotation speed of the rotating frame 3 and avoid shaking caused by excessive rotation.

[0025] The bracket 1 includes two bottom plates, both of which are provided with positioning holes, and positioning rods 15 are inserted into the positioning holes. The bracket 1 as a whole can be quickly positioned by burying the positioning rods 15 downwards into the soil.

[0026] Working principle: When in use, the bracket 1 is placed as a whole on the soil to be measured, and the motor drives the rotating frame 3 to rotate. The two sliding blocks 4 distributed in an annular manner on the rotating frame 3 slide in the arc groove 5 on the fixed plate 2, and the fixed rod 6 passing through the through hole of the sliding block 4 moves accordingly. When the rotating frame 3 is rotated to the appropriate position, the fixed block 7 on the fixed rod 6 with the drill rod 10 is located below the push block 9. The cylinder extends and presses down the fixed block 7 and the fixed rod 6 through the push block 9. At this time, the reset spring 8 is stretched and in a stretched state. The fixed rod 6 moves downward to drive the drill rod 10 to drill into the soil, and then the cylinder retracts. The fixed rod 6 and the drill rod 10 move up and back to their positions under the elastic recovery action of the spring, and then the motor drives the rotating frame 3 to rotate again, so that the fixed rod 6 with the probe 11 moves to the bottom of the push block 9, and the cylinder extends and presses down the fixed rod 6 again, and the fixed rod 6 drives the probe 11 to be inserted into the drilled soil hole for measurement. Compared with the traditional soil measuring instrument, the automation of soil measurement is realized, the labor intensity of the operator is reduced, and the design of pre-drilling the drill rod 10 and then safely inserting the probe 11 effectively solves the problem of easy damage to the probe 11 when operating in hard soil.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
