5results about How to "Improve soil extraction efficiency" patented technology

The invention relates to the technical field of soil sampling, and discloses a mining area soil rapid sampler based on coal mining safety monitoring, which comprises a soil sampling tube, a rotating tube arranged on the top of the soil sampling tube, handles arranged on the two sides of the rotating tube, and a soil sampling unit arranged in the soil sampling tube, the soil sampling unit comprises a communicating component arranged at the top of the soil sampling pipe and a soil sampling component arranged at the bottom of the communicating component; the soil sampling part is used for pushing the soil sampling pipe to rotate to sample soil in the downward pressing process of the rotating pipe, and the communicating part is used for communicating the soil sampling pipe with external air in the soil sampling process of the soil sampling part, so that soil can enter the soil sampling pipe conveniently. According to the soil sampling device, the soil sampling pipe can be continuously pushed to rotate in one direction through the arranged soil sampling component, rotary soil sampling of the soil sampling pipe can be achieved without repeatedly rotating the rotating pipe, the labor intensity of soil sampling personnel is reduced, and the soil sampling efficiency is improved.

The invention belongs to the technical field of interplanting, and discloses an ecological tea garden herbaceous plant interplanting machine which comprises a rack, a handrail is fixedly installed at the right end of the rack, longitudinal guide rails are fixedly installed on the left side and the right side of the bottom end of the rack correspondingly, and bottom plates are fixedly installed at the bottom ends of the two longitudinal guide rails correspondingly; trundles are movably installed at the front ends of the two bottom plates, a compaction roller is movably connected to the rear end between the two bottom plates, and an operation assembly is installed at the bottom end of the rack. Through the cooperation between the control assembly and the soil sampling assembly and the cooperation between the soil sampling assembly and the electric push rod, the soil sampling cone can descend and ascend only by rotating a hand wheel for two circles, the soil sampling process is synchronously completed in the ascending process, the whole process can be synchronously completed, namely hole digging and soil sampling can be completed at the same time, and the working efficiency is greatly improved. The soil in the target area can be rapidly taken out without two working procedures, and the overall soil taking efficiency is remarkably improved.

The utility model discloses a soil collecting device for environmental impact assessment, including base, the top of base is fixedly connected with circular ring, the top of base is in the inside of circular ring and is seted up with adjusting groove, the inside of adjusting groove is installed with bearing, the top of carousel is fixedly connected with the sleeve of cylinder, the inside of sleeve of cylinder all is installed with height column, and the top of height column is respectively connected with moving block and rotating block through screw rod rotation, and the angle plate is arranged between moving block and rotating block, and the adjusting groove is seted up on angle plate, and one end of moving block extends to the top of angle plate through adjusting groove and is connected with angle plate slidingly, and rotating block is fixedly connected with angle plate, and the limit slot is seted up on the top of angle plate and in the both sides of adjusting groove. Compared with traditional device, the device is not only more convenient to use, and is more suitable for the standard operation of multiple sampling of a piece of land in environmental assessment.

The utility model relates to the technical field of soil sampling devices, in particular to an efficient cutting ring soil sampling device. According to the technical scheme, the device comprises a fixed sleeve, a knock-down hammer is movably sleeved with the fixed sleeve, the upper end of the knock-down hammer is fixedly connected with a connecting rod, and the upper end of the connecting rod penetrates through the fixed sleeve and extends to be connected with double handles; the first spring sleeves the outer wall of the connecting rod, the lower end of the first spring is fixedly connected with the knock-down hammer, and a limiting assembly for adjusting the elasticity of the first spring is arranged at the upper end of the fixed sleeve; the fixed cylinder is fixedly arranged at the lower end of the fixed sleeve, and a cutting ring for sampling soil is arranged in the fixed cylinder in a sliding manner. According to the utility model, the cutting ring is knocked into soil by utilizing the free falling motion of the knock-down hammer and converting gravitational potential energy into kinetic energy, so that compared with direct manual pressing, the labor cost is greatly saved, and the soil sampling efficiency is improved.

This invention belongs to the field of intercropping technology and discloses a herbaceous plant intercropping machine for ecological tea gardens. The machine includes a frame, a handrail fixedly installed at the right end of the frame, longitudinal guide rails fixedly installed on both the left and right sides of the bottom of the frame, base plates fixedly installed at the bottom ends of the two longitudinal guide rails, casters movably installed at the front ends of the two base plates, and a compaction roller movably connected between the rear ends of the two base plates. An operating component is installed at the bottom of the frame. This invention utilizes the cooperation between the operating component and the soil-collecting component, as well as the cooperation between the soil-collecting component and the electric push rod, to achieve the lowering and raising of the soil-collecting cone with only two rotations of the handwheel. During the raising process, the soil-collecting process is completed simultaneously. The entire process can be completed synchronously, that is, digging and soil collection can be completed at the same time, eliminating the need for two separate processes and enabling rapid extraction of soil from the target area, significantly improving overall soil-collecting efficiency.
