Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a soil survey sample sampling equipment. Background Art

[0002] The main function of soil survey sample sampling equipment is to sample the soil and collect a certain amount of samples from the soil for subsequent soil property measurement, analysis and testing. The collected samples can be used to measure various properties of the soil, such as properties, composition, particulate matter and moisture. By analyzing these samples, we can understand the soil fertility, pollution status, changes in soil quality and other information, which has important guiding significance for the formulation of environmental protection policies, agricultural production and land use planning.

[0003] Existing soil survey sample sampling equipment is not convenient for automatic sampling during use, and most of the sampling operations rely on manual operations. Although this method is feasible, when the number of samples to be collected is too large, it not only increases the difficulty and intensity of manual operation, but may also affect the accuracy and efficiency of sampling.

[0004] Patent document CN219935350U discloses a soil sampling device, "including a sampling tube and a sampling unit; a driving unit is arranged inside the sampling tube, a ratchet assembly is arranged at the upper end of the sampling tube, a handrail is arranged on the ratchet assembly, and the sampling unit is arranged on the sampling tube. The beneficial effect is: soils of different depths are sampled simultaneously by multiple groups of storage boxes arranged on the sampling tube, which effectively improves the sampling efficiency and reduces the workload during sampling; samples of different depths are placed separately by the storage boxes, and the soil samples in the storage boxes are sealed and isolated by the scraper, which effectively avoids the mixing of samples and other soils, ensures the accuracy of the samples and the accuracy of the test results, collects soil samples by the movable storage boxes, facilitates the removal of samples in the storage boxes, and improves the convenience of taking out soil samples." However, the soil sampling device of the above-mentioned public document mainly considers the convenience of removing samples from the storage boxes, but does not consider the problem of automatic soil sampling. Therefore, it is necessary to develop a soil survey sample sampling device. Utility Model Content

[0005] The utility model aims to provide a soil survey sample sampling device to solve the technical problem that it is inconvenient to automatically sample soil samples in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soil survey sample sampling device, comprising a base and a frame fixedly installed on the base, an electric push rod fixedly installed inside the frame, one end of the electric push rod fixedly connected to a support plate, a box fixedly installed on the support plate, a stepper motor fixedly installed inside the box, an output end of the stepper motor fixedly connected to a sampling cylinder, a drill bit fixedly connected to the bottom end of the sampling cylinder, a controller fixedly installed on the top of the frame, and the controller is electrically connected to the electric push rod, a battery assembly fixedly installed on the frame, and the battery assembly is electrically connected to the controller.

[0007] Preferably, the support plate is symmetrically provided with through holes, a guide rod is passed through the through hole, and one end of the guide rod is fixedly connected to the inner wall of the frame.

[0008] Preferably, a handle is fixedly mounted on the base, and supporting legs are symmetrically mounted on the bottom of the base.

[0009] Preferably, a vibrator is provided on the frame, a positioning plate is fixedly mounted on the vibrator, and the positioning plate is fixedly connected to the frame by bolts.

[0010] Preferably, a motor is fixedly installed inside the vibrator, and a rotating disk is fixedly connected to the output end of the motor.

[0011] Preferably, the rotating disk is movably connected to a driving frame, and the driving frame is movably connected to a driving rod.

[0012] Preferably, a cylinder is fixedly installed inside the vibrator, and a driving rod is passed through the inside of the cylinder. One end of the driving rod is fixedly connected to a knocking head, and the knocking head is made of rubber material.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is convenient for the soil survey sample sampling device to automatically sample samples through the installed electric push rod and sampling tube. When the soil survey sample sampling device is used to sample soil samples, after the base is placed at the sampling location, the stepper motor and the electric push rod are controlled by the controller to work. The electric push rod will push the support plate to move, and the support plate will drive the box to move when it moves, and then the sampling tube and the drill bit will move downward. At the same time, the stepper motor inside the box will work to rotate the output end through the sampling tube to drive the drill bit to rotate. After the drill bit contacts the soil, the soil will be drilled, and the drilled soil enters the sampling tube for collection, thereby achieving the purpose of automatic sampling and reducing labor intensity.

[0015] 2. The utility model installs a vibrator to facilitate the taking of samples collected by the soil survey sample sampling equipment. The motor works to drive the rotating disk to rotate. When the rotating disk rotates, the driving frame cooperates to make the driving rod repeatedly move its position inside the cylinder. When the driving rod moves, it drives the knocking head to move. The movement of the knocking head will knock on the outer wall of the sampling tube, which will make the sampling tube vibrate, making it easier for the collected soil sample to slide to the outside, thereby achieving the purpose of facilitating the taking of soil samples and improving the practicality of the soil survey sample sampling equipment.
