Description

Technical Field

[0001] The utility model belongs to the technical field of mountain chestnut planting, and particularly relates to a soil sampling device for detecting mountain chestnut planting soil samples. Background Technique

[0002] When chestnut is planted, it is necessary to sample the soil and analyze the components contained therein, so as to study whether the soil components in this area are suitable for planting a certain crop.

[0003] For example, the Chinese patent with the publication number CN220794680U discloses a sampling device for soil sampling and detection, including a box body. One side of the top end inside the box body is fixedly connected with a first mounting plate. A circular opening is formed on one side of the bottom surface inside the box body. An electric push rod is fixedly installed on the bottom surface of the first mounting plate. The bottom end of the electric push rod is fixedly connected with a second mounting plate. A rotating motor is fixedly installed on the bottom surface of the second mounting plate. The bottom end of the rotating motor is fixedly welded with a rotating shaft. The bottom end of the rotating shaft is fixedly installed with a connecting block. A threaded pipe is welded on the bottom surface of the connecting block. A threaded ring cutter is welded on the circumferential side of the threaded pipe. When in use, the mutual cooperation of the mounting plate, the electric push rod, the rotating motor, the threaded pipe, the threaded ring piece (which can make the sampling pipe better enter the soil), the connecting rod slider, the sliding rod, and the fixing plate improves the sampling efficiency of the sampling device for soil detection, increases the service life of the instrument, and speeds up the detection process.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use. For example, when the above device is in use, it is simply placed on the ground without being fixed, which may cause the device to tilt during use. In this way, the barrel may tilt when inserted into the hole, resulting in difficult insertion. At the same time, when the above device is in use, it relies on the elastic force of the spring to reset several cylinders. If the cylinder gets stuck in the hole, the elastic force of the spring may not be able to pull it back, resulting in the device being unable to be pulled out. In view of this, we propose a soil sampling device for detecting mountain chestnut planting soil samples. Content of the Utility Model

[0006] The purpose of the utility model is to provide a soil sampling device for detecting mountain chestnut planting soil samples to solve the problems raised in the above background technique.

[0012] In this technical solution, first, place the overall device on the ground. Through the provided driving component, the two first threaded rods can be driven to rotate. Under the action of the thread, the two first threaded rods respectively drive the two support columns to slide downward. When both support columns enter the soil, the overall device does not need to be held by personnel, and the overall device will not tilt during use;

[0013] When soil needs to be taken, first start the cylinder. The output end of the cylinder drives the sliding block to slide downward. The sliding block drives the rotating block and the drill bit to move downward. At the same time, start the motor. The motor drives the drill bit to rotate. Then the drill bit will drill a hole in the ground. Then the output end of the cylinder drives the sliding block, the rotating block and the drill bit to move upward. When the drill bit completely disengages from the hole, the personnel rotate the rotating block and drive the drill bit and the fixing column to rotate 90°. Then start the cylinder. The output end of the cylinder drives the fixing column to slide downward and insert it into the hole. Through the provided power component, a plurality of sliding columns can be driven to enter the soil. Then the soil will enter the sliding columns and be collected. Through the provided power component, a plurality of sliding columns can be driven to enter the fixing column to complete the soil-taking work. Then the output end of the cylinder drives the sliding block, the rotating block and the fixing column to move upward. When the fixing column completely disengages from the hole, the soil-taking work is completed, which can ensure that a plurality of sliding columns can smoothly retract into the fixing column after the soil-taking is completed.

One end of the second bevel gear penetrates through the power chamber and extends to the outside.

[0020] In this technical solution, when soil needs to be taken, first start the air cylinder. The output end of the air cylinder drives the sliding block to slide downward. The sliding block drives the rotating block and the drill bit to displace downward. At the same time, start the motor, and the motor drives the drill bit to rotate. Then the drill bit will drill a hole in the ground. Then the output end of the air cylinder drives the sliding block, the rotating block and the drill bit to displace upward. When the drill bit completely disengages from the hole, the person rotates the rotating block and drives the drill bit and the fixed column to rotate 90°. Then start the air cylinder.
