Description

Technical Field

[0001] This utility model relates to the field of agricultural implements technology, and in particular to a novel soil sampling device. Background Technology

[0002] In modern agriculture and forestry production, it is frequently necessary to sample and test the planting soil to check various indicators such as soil moisture content, pH, and EC value. With increasing soil salinization and more frequent and diverse pollution, the requirements for soil sampling in plant cultivation are becoming increasingly stringent. However, the commonly used soil auger is similar to a Luoyang shovel, requiring considerable force to drive it into the soil. Even with two strong individuals, at least five sampling points are needed per area, and this number increases exponentially in larger planting areas. This makes sampling laborious and time-consuming. Furthermore, after meeting the sampling standards, the compacted soil sample must be painstakingly removed from the sampling hole and poured into a sealed plastic bag for measurement, which is both time-consuming and laborious.

[0003] Therefore, to address the above shortcomings, a new type of soil sampling device is needed. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] A new type of soil sampling device, combined with Figure 3 , Figure 4 The device includes a motor 1, a drive assembly 2, a hammer 3, a punch rod 4, a soil drill 5, and a main housing 6. The motor 1 is fixed inside the main housing 6. The drive assembly 2 is mounted on the main housing 6 and its input end is rotatably connected to the motor 1. The output end of the drive assembly 2 is slidably connected to the bottom of the main housing 6. The hammer 3 is slidably connected to the bottom of the drive assembly 2 and is clearance-fitted with the drive assembly 2. One end of the punch rod 4 extends into the main housing 6 and intermittently contacts the hammer 3. The other end of the punch rod 4 extends out of the main housing 6 and is fixedly connected to the soil drill 5. The soil drill 5 extends into the ground to extract soil.

[0027] Combination Figure 1 , Figure 4 The main housing 6 is a roughly square-shaped shell with ventilation holes. Its surface is equipped with electronic components such as a charging port or screen. Power supplies and controllers are located on either side of the drive assembly 2. A motor cylinder 61 is fixedly connected to the front end of the main housing 6, and the motor 1 is placed inside the motor cylinder 61 and fixedly connected to the front end of the main housing 6. The output of the motor 1 is connected to the drive assembly 2 via a coupling and a shaft. Cylindrical handles 62 are fixedly connected to the left and right sides of the main housing 6. The handles 62 are hollow inside and have cables running through them, connecting to the controller. A switch is located on the outer end of the handle 62, allowing the sampling personnel to start the motor 1 by pressing it with their thumb and stop it by releasing it, thus improving equipment safety.

[0028] Combination Figure 3 , Figure 4 The drive assembly 2 includes a rotary wheel 21, a connecting rod 22, a drive rod 23, and a piston 24. The rotary wheel 21 has a disc-shaped structure and is rotatably connected to the output end of the motor 1 at its center. One end of the strip-shaped connecting rod 22 is rotatably connected to an eccentric end face of the rotary wheel 21, and the other end of the connecting rod 22 is rotatably connected to the strip-shaped drive rod 23. The drive rod 23 is hinged to the piston 24. A cylindrical stroke cylinder 63 is fixedly connected to the bottom of the main housing 6. A cylindrical sleeve 64 is threaded to the bottom of the stroke cylinder 63. The inner diameter of the sleeve 64 is smaller than the inner diameter of the stroke cylinder 63 to limit the stroke of the hammer 3. The piston 24 is slidably connected inside the stroke cylinder 63, and the outer diameter of the piston 24 is the same as the inner diameter of the stroke cylinder 63. By setting up the drive assembly 2, the rotational motion of the motor 1 is converted into linear reciprocating motion, transmitting power for the impact of the soil drill.

[0029] Combination Figure 3 , Figure 4 The hammer 3 includes a cylindrical buffer section 31 and an impact section 32, both of which are solid metal blocks. The outer diameter of the buffer section 31 is larger than that of the impact section 32. The outer diameter of the buffer section 31 is the same as the inner diameter of the stroke cylinder 63 and is slidably connected within the stroke cylinder 63. One end of the impact section 32 is fixedly connected to the buffer section 31, and the other end of the impact section 32 extends into the sleeve 64. The outer diameter of the impact section 32 is slightly smaller than the inner diameter of the sleeve 64. A solid punch 41 is fixedly connected to one end of the punch rod 4 that extends into the sleeve 64. The punch 41 is cylindrical, and its outer diameter is also smaller than the inner diameter of the sleeve 64. Air is injected into the stroke cylinder 63 between the buffer section 31 and the piston 24 to form an air chamber 25. The buffer section 31 does not contact the piston 24.

[0030] As the piston 24 moves upward within the stroke cylinder 63, the change in gas pressure within the air chamber 25 also causes the hammer 3 to slide upward within the stroke cylinder 63 and sleeve 64. When the hammer 3 overcomes gravity and reaches its highest point, the piston 24 moves downward, compressing the air chamber 25. At this time, under the action of gas pressure and gravity, the hammer 3 accelerates downward, causing the impact part 32 to disengage from the punch 41 to provide impact pressure, which is equivalent to providing artificial downward pressure, allowing the soil drill 5 to be inserted into the soil for soil sampling. Then, by relying on multiple impacts, the soil drill 5 can be continuously pressed down, thereby allowing the soil drill 5 to be inserted into deeper soil layers to meet sampling requirements. The air chamber 25 is provided to prevent the hammer 3 from contacting the piston 24 and causing impact damage to the drive assembly 2.

[0031] Combination Figure 1 , Figure 3The punch 4 is a tubular metal rod with a length of not less than one meter. The intermittent contact between the punch 41 and the impact part 32 provides downward pressure to the punch 4. A strip-shaped groove 42 is formed on the punch 4 below the punch 41. A limiting rod 65 is threadedly connected to the sleeve 64. The limiting rod 65 is a cylindrical rod with threads only at the end connected to the sleeve 64, and the rest is a smooth rod. The outer diameter of the smooth rod is equal to the inner diameter of the groove 42. The limiting rod 65 extends into the groove 42 to allow the punch 4 to slide and connect with the limiting rod 65. The limiting rod 65 prevents the punch 4 from slipping out of the sleeve 64, allowing the punch 4 to slide and connect with the sleeve 64.

[0032] During use, the sampling personnel continuously press down on the main housing 6 using the handle 62. At this time, the punch 41 and the punch rod 4 extend into the sleeve 64 until the limiting rod 65 abuts against the bottom of the chute 42. Then, the hammer 3 falls, impacting the punch 41 and the punch rod 4 downwards until the limiting rod 65 contacts the top of the chute 42. If the soil layer is hard, the downward movement distance will be shorter, and there is a possibility that they will not make contact. In addition, the stroke cylinder 63 is provided with a limiting platform 67 at the top of the sleeve 64. A rubber pad is fixed to the bottom of the buffer part 31. The contact between the rubber pad and the limiting platform 67 limits the stroke of the hammer 3, preventing greater impact on the limiting rod 65, and reduces the impact of the hammer 3 on the stroke cylinder 63 and the sleeve 64, thus reducing the vibration felt by the sampling personnel. A petal-shaped handwheel 66 is fixed to one end of the limiting rod 65 extending out of the sleeve 64. The outer diameter of the handwheel 66 is larger than the outer diameter of the limiting rod 65, so that the sampling personnel can rotate the limiting rod 65 to install or remove it.

[0033] Combination Figure 1 , Figure 2 The soil drill 5 is a metal cylinder with an open bottom. The bottom of the soil drill 5 has a conical opening 51 to make the bottom sharp, so that the soil drill 5 can be better inserted into the soil layer to extract soil. The soil drill 5 has strip-shaped soil extraction grooves 52 on both sides that penetrate the soil drill 5. After extracting soil, a wooden stick or metal stick can be inserted into the soil extraction groove 52 at the top of the soil drill 5 and moved down along the soil extraction groove 52 to remove the soil clods inside the soil drill 5, which is very convenient.

[0034] In summary, this invention, through electric drive combined with the principle of an electric hammer, and employing a heavy-duty hammer 3 and a low-frequency impact mode, can not only replace manual labor in inserting the soil drill 5 into deeper soil layers for soil sampling, but also reduce vibration discomfort for sampling personnel, thus improving practicality. Furthermore, the device has a simple structure, making it easy to transport and store, and its operation is simple and easy to learn, facilitating widespread use.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
