Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a soil sampling device for the roots of flue-cured tobacco in a test field. Background Technique

[0002] Soil is the basis for the growth of crops, and soil properties determine whether crops can grow normally and healthily. To a certain extent, the color of the soil body can be used as a sign to judge whether it is suitable for growing high-quality flue-cured tobacco. Generally, the tobacco leaves produced on the soil with a yellow or red color have better quality. The nutrients in the soil determine the growth of flue-cured tobacco. To achieve the healthy growth of flue-cured tobacco, it is usually necessary to detect the soil at the location where the flue-cured tobacco grows.

[0003] In the prior art, a soil sampling drill cylinder and a soil sampler disclosed in the Chinese utility model patent with the publication number of CN214502953U include a drill cylinder body and a spiral line. The drill cylinder body is in a cylindrical shape and has a preset rotation direction. The spiral line is connected to the inner surface of the drill cylinder body. The spiral line forms a spiral protrusion on the inner surface of the drill cylinder body. The advancing direction of the spiral line matches the preset rotation direction, so that when the drill cylinder body rotates in the preset rotation direction, the spiral line can suck the soil into the soil sampling drill cylinder. The soil sampler includes a power device and the above-mentioned soil sampling drill cylinder. The output end of the power device is connected to the soil sampling drill cylinder, and the rotation direction of the output end of the power device matches the preset rotation direction.

[0004] However, during the process of drilling and sampling soil with the soil sampling drill cylinder of the above device, some relatively loose soil is likely to fall out of the soil sampling drill cylinder, resulting in the failure of the soil sampling work. Moreover, in winter outdoors or when the temperature is relatively low, the soil is relatively hard, and it is difficult to insert the sampling tube into the soil. The labor intensity of the user is high, it is time-consuming and laborious, and the sampling efficiency is low. Therefore, it does not meet the existing requirements. For this reason, we propose a soil sampling device for the roots of flue-cured tobacco in a test field. Content of the Utility Model

The water trough 511 and the conical shell 509 are provided with leakage holes 510 at the lower sides of the outer surface. When the whole device is inserted into the soil, the conical shell 509 will move upward a certain distance on the inner side of the vertical pipe 501. The upward movement of the conical shell 509 drives the top rod 503 to move upward, thereby driving the baffle 502 to move upward.

The upper end surface of the rotating shaft is rotatably connected to the inner wall of the square housing 701 through a bearing, and the lower end surface of the rotating shaft is fixedly connected to the upper end surface of the threaded rod 801. A conveyor belt 705 is sleeved on the outer surfaces of the active gear 702 and the driven gears 703. A plurality of saw teeth 704 are evenly installed on the inner surface of the conveyor belt 705. The saw teeth 704 are engaged with both the active gear 702 and the driven gears 703. By rotating the turntable 3, the vertical shaft 4 can be driven to rotate. The rotation of the vertical shaft 4 can drive the short shaft to rotate, and then drive the active gear 702 to rotate, driving the lead screw 901 to rotate. The active gear 702 is engaged with the saw teeth 704, thereby driving the conveyor belt 705 to drive, driving the two driven gears 703 to rotate, and then driving the rotating shaft to rotate, driving the threaded rod 801 to rotate.

[0029] As Figure 5 and Figure 6 shown, the lower end surface of the threaded rod 801 is rotatably connected to a limiting plate through a bearing. The limiting plate is fixedly connected to the inner wall of the circular cavity through a cross plate. The lower end surface of the cylindrical sleeve A802 is fixedly connected to a base 803. A motor is installed in the base 803 through a motor cavity. The output end of the motor is fixedly connected to a pin shaft. The lower end surface of the pin shaft is fixedly connected to a drill bit 805. Two fixed blades 804 are fixedly installed on both sides of the outer surface of the drill bit 805. When the threaded rod 801 rotates, since the cylindrical sleeve A802 is threadedly connected to the threaded rod 801, at this time, the cylindrical sleeve A802 moves downward on the outer surface of the threaded rod 801, driving the base 803 to move downward. And by setting the limiting plate, it can prevent the cylindrical sleeve A802 from falling off the outer surface of the threaded rod 801. The motor works to drive the drill bit 805 and the fixed blades 804 to rotate, and can drill deep into the soil.

[0030] The lower end face of the lead screw 901 is rotatably connected to a limit block through a bearing. The limit block is fixedly connected to the inner wall of the circular cavity through a support plate.

A partition plate 908 is installed in the groove 906 through an electric push rod 907. When the lead screw 901 rotates, since the cylindrical sleeve B902 is threadedly connected to the lead screw 901, at this time, the cylindrical sleeve B902 moves downward on the outer surface of the lead screw 901, driving the sampling cylinder 903 to move downward. By providing a limit block, it is possible to prevent the cylindrical sleeve B902 from falling off the outer surface of the lead screw 901. After the sampling is completed, the switch of the electric push rod 907 can be controlled to make the two partition plates 908 seal the opening 905 to prevent the soil from falling out of the sampling cylinder 903, resulting in the failure of the soil sampling work.

[0031] Working principle: When the flue-cured tobacco root soil sampling device in this experimental field is in use, through the irrigation mechanism 5 and the water injection port 2 provided, water can be injected into the water injection groove through the water injection port 2. The heating wire can heat the water in the water injection groove. When the whole device is inserted into the soil, the conical shell 509 will move upward a certain distance inside the vertical pipe 501. The upward movement of the conical shell 509 drives the ejector rod 503 to move upward, thereby driving the baffle 502 to move upward. At this time, the hot water can flow to the lower part of the fixed plate 505 through the gap between the baffle 502 and the through hole 504, enter the conical shell 509 through the water inlet groove 511, and then wet the soil through the water leakage holes 510 to make the soil moist. By providing a transmission mechanism 7, a soil drilling mechanism 8 and a sampling mechanism 9, by rotating the turntable 3, the drill bit 805 and the sampling cylinder 903 can be driven to move downward. The drill bit 805 and the fixed blade 804 rotate and can drill deep into the soil. At the same time, when it is necessary to sample the soil at a certain depth, the electric push rod 907 can be controlled to make the two partition plates 908 retract into the inner side of the groove 906, exposing the opening 905. At this time, the sampling cylinder 903 continues to move downward, and the soil will enter the collection cavity 904 through the opening 905. After the sampling is completed, the switch of the electric push rod 907 can be controlled again to make the two partition plates 908 seal the opening 905 to prevent the soil from falling out of the sampling cylinder 903, resulting in the failure of the soil sampling work. This utility model is convenient to carry. By providing an irrigation mechanism 5, it is convenient for the soil drilling mechanism 8 and the sampling mechanism 9 to insert deep into the soil, saving time and effort, and can collect the soil at a certain depth and prevent the soil from falling out of the sampling cylinder 903.
