Description

Technical Field

[0001] This utility model relates to the field of hydrology, and in particular to a hydrogeological stratification sampling device. Background Technology

[0002] An existing patent (publication number: CN214667843U) discloses a hydrogeological stratified sampling device. It includes a mobile trolley, a rotating mechanism, a sampling mechanism, and an observation mechanism mounted above the trolley, as well as a lighting mechanism located on the side of the trolley. The sampling mechanism is mounted on the rotating mechanism, which includes a screw rod and a power assembly, with the screw rod mounted on the power assembly. The sampling mechanism includes three sampling chambers arranged sequentially from bottom to top inside the screw rod. However, this device, where the screw rod is mounted on the power assembly, relies on the screw rod at the front of the mobile trolley for soil drilling and sampling. Because the screw rod is at an inclined angle, if the ground has a certain angle of inclination, the device needs to be additionally supported, which has certain limitations. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a hydrogeological stratification sampling device that allows for geological sampling operations via a drill bit at the front of the equipment frame. When the ground has an inclination angle, rotating the internal threaded cylinder handwheel on the side of the angle frame raises and lowers the internal threaded cylinder while simultaneously releasing the locking mechanism on the toothed pressure plate. Furthermore, rotating the handwheel at the front of the angle shaft allows the angle shaft to adjust the drilling angle of the drill bit at the bottom of the frame. This increases the adaptability of the equipment.

[0004] The objective of this utility model is achieved through the following technical solution: A hydrogeological stratified sampling device includes an equipment frame, wheels, a toothed pressure plate, an internally threaded cylinder handwheel, an internally threaded cylinder, a guide wheel shaft, a guide wheel, a motor frame, and a drive shaft. The lower part of the equipment frame is fixedly connected to the wheels, the rear part of the equipment frame is fixedly connected to a push rod, and the front part of the equipment frame is fixedly connected to an angle frame. The angle frame has an angle shaft groove inside, and the side of the frame is fixedly connected to the angle shaft. The angle shaft groove is adapted to the angle shaft and connects to the angle shaft, allowing the angle shaft to rotate within the angle shaft groove. The front part of the angle shaft is fixedly connected to the handwheel, and the rear part of the angle shaft is fixedly connected to a pointer. The rear part of the angle frame has a scale, and the pointer corresponds to the scale position. The side of the angle frame has a sliding groove, and the side of the angle shaft is fixedly connected to a screw seat. The sliding groove is adapted to the screw seat and connects to the screw seat, allowing the screw seat to slide within the sliding groove. The upper part of the screw seat is fixedly connected to a screw. The toothed pressure plate slides below the screw. The surface of the angle frame has teeth that are adapted to the toothed pressure plate.

[0005] The toothed connection is a toothed pressure plate, which is inserted into the toothed groove. The internal threaded cylinder handwheel is fixedly connected to the internal threaded cylinder, and the upper part of the screw is threadedly connected to the internal threaded cylinder.

[0006] The toothed pressure plate is pressed against the upper part of the toothed pattern by an internal threaded cylinder. The front part of the frame is fixedly connected to the cylinder, the lower part of the cylinder is fixedly connected to the lifting plate, and the side of the lifting plate has a guide wheel shaft. Beneficial effects

[0007] 1. During the use of this utility model hydrogeological stratified sampling device, geological sampling is performed by the drill bit at the front of the equipment frame. If the ground has an inclination angle, the internal threaded cylinder handwheel on the side of the angle frame is rotated to raise and lower the internal threaded cylinder while releasing the locking of the toothed pressure plate. The handwheel at the front of the angle shaft is rotated to adjust the drilling angle of the drill bit at the bottom of the frame, thereby increasing the adaptability of the equipment.

[0008] 2. During the use of this utility model hydrogeological stratified sampling device, the cylinder at the top of the frame drives the drill bit at the bottom of the lifting plate to move up and down. At the same time, the four sets of guide wheels on the side of the lifting plate guide the drill bit on the side of the guide rail. When drilling at an angle, the device avoids the cylinder from being misaligned and jammed due to force on one side, thereby increasing the stability of the equipment.

[0009] 3. During the use of this utility model hydrogeological stratified sampling device, the two sets of toothed pressure plates on the side of the angle frame lock the screw seat on the side of the angle shaft, and the toothed pressure plates are engaged in the toothed grooves, thereby increasing the stability of the toothed pressure plates locking the angle shaft.
