Technical Field

[0001] The present invention relates to the technical field of soil sampling, and particularly to a soil exploration sampling device. Background Art

[0002] Desert areas are rich in salt mines and silicon mines. Therefore, during geological exploration work, staff often need to sample and analyze the soil in desert areas to detect the mineral components and the content of each component in the area.

[0003] A common soil sampling device is a thin-walled container with one end open. When sampling soil, the open end is aligned with the ground and a downward pressure is applied. The open end of the container will insert into the ground, and the soil will adhere to the inner wall of the container, so that the sampled soil will not fall off when the container is pulled out of the ground.

[0004] However, when the above common soil sampling device samples the border area at the edge of the desert, after soils with different properties and particle sizes enter the container, the adhesion of the soil composed of particulate matter between the inner walls of the container is insufficient. When the container is pulled out of the ground, the sampled soil may fall off from the container, affecting the efficiency of geological personnel for soil sampling. Summary of the Invention

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Refer to Figures 1 - 9, A soil exploration sampling device, including two front and rear baffles 1 and two left and right side plates 2. The two front and rear baffles 1 are arranged in parallel, and the two left and right side plates are fixedly connected at intervals between the two front and rear baffles 1. At the top of one side of the front and rear baffles 1, a winding shaft 114 is rotatably installed, and a wear-resistant fabric 113 is wound around the winding shaft 114. A U-shaped notch 101 is penetrated through the two front and rear baffles 1, and a protective plate 3 is covered on the surface of the front and rear baffles 1 to protect the notch 101. A sliding seat 103 is slidably fitted in the notch 101, and a U-shaped connecting piece 104 is fixedly connected to the sliding seat 103. The end of the wear-resistant fabric 113 is fixedly connected to the connecting piece 104.

[0029] The two front and rear baffles 1 and the two left and right side plates 2 are connected to form a container for soil sampling. When sampling soil, since a force-applying handle 4 is fixedly connected to the top of the front and rear baffles 1, the staff holds the force-applying handle 4 with both hands and applies force downward with the container aligned with the ground, then the front and rear baffles 1 and the left and right side plates 2 can be inserted into the ground, and soil sampling can be carried out.

[0030] As Figures 6 - 8 shown, a traction rope 112 is provided in the notch 101. One end of the traction rope 112 is fixedly connected to the sliding seat 103 to apply a pulling force to the sliding seat 103, and the other end of the traction rope 112 is connected to a winding structure.

[0031] The winding structure drives the traction rope 112 to move along the inner wall of the notch 101. Under the pulling force of the traction rope 112, the wear-resistant fabric 113 on the connecting piece 104 first moves downward along the notch 101. After the wear-resistant fabric 113 moves to the bottom end of the notch 101, the wear-resistant fabric 113 will move horizontally under the pulling force of the traction rope 112, cutting the sampled soil in the container from the bottom and closing the bottom of the container to prevent the soil inside the container from falling during the process of pulling the container upward.

[0032] As Figure 7 shown, the winding structure includes a winding disc 5. The winding disc 5 is rotatably installed on the outer wall of the front and rear baffles 1. The end of the traction rope 112 is fixedly connected to the winding disc 5. A ratchet wheel 6 is coaxially fixedly connected to the outer wall of the winding disc 5. A limiting pawl 7 is hinged on the surface of the front and rear baffles 1. The limiting pawl 7 cooperates with the ratchet wheel 6 to prevent the ratchet wheel 6 from rotating in the reverse direction. A handle 8 is rotatably installed inside the front and rear baffles 1. A driving pawl 9 is hinged on the handle 8. The driving pawl 9 cooperates with the ratchet wheel 6 to drive the ratchet wheel 6 to rotate.

[0033] During the reciprocating rotation of the handle, due to the one-way transmission structure formed by the cooperation of the ratchet wheel 6 and the driving pawl 9, the ratchet wheel 6 continuously rotates in one direction. During the one-way rotation of the ratchet wheel 6, it will drive the winding disc 5 to rotate synchronously. During the rotation of the winding disc 5, the traction rope 112 will be wound up to apply a pulling force to the wear-resistant fabric 113.

[0034] As Figure 8 shown, a turntable 115 is rotatably installed on the outer wall of the front and rear baffle plates 1. The turntable 115 is fixedly connected to the take-up reel 114. A plurality of limiting grooves 116 are equally spaced on the turntable 115. A sliding tube 117 is fixedly connected to the outer wall of the front and rear baffle plates 1. A sliding rod 118 is slidably fitted in the sliding tube 117. A wedge-shaped block 105 is fixedly connected to the end of the sliding rod 118. The block 105 cooperates with the limiting groove 116. A compression spring 119 is sleeved on the outer part of the sliding rod 118 to apply an elastic force to the block 105.

[0035] The wedge-shaped block 105 is located inside the limiting groove 116 under the elastic force of the compression spring 119, so that the turntable 115 is limited within a certain external force range, thereby preventing the take-up reel 114 from rotating accidentally and causing the stretching length of the wear-resistant fabric 113 to exceed the required value.

[0036] As Figure 9 and Figure 10 shown, a cutting structure is provided on the connecting member 104 for cutting the bottom of the collected soil. The cutting structure includes a wire saw driving wheel 110. The wire saw driving wheel 110 is rotatably installed on the outer wall of the connecting member 104. A wire saw 111 is fitted on the wire saw driving wheel 110. A driving structure is provided on the connecting member 104 for driving the wire saw 111 to operate. The driving structure includes a rotating shaft 106. The rotating shaft 106 is rotatably installed on the connecting member 104. A driven gear 107 is fixedly connected to the end of the rotating shaft 106. A rack 102 is fixedly connected to the inner wall of the notch 101. The driven gear 107 matches the rack 102. A driving gear 109 is fixedly connected to the outer wall of the rotating shaft 106. An end face gear 108 is rotatably installed on the inner wall of the connecting member 104. The end face gear 108 is fixedly connected to the wire saw driving wheel 110. The end face gear 108 matches the driving gear 109.

[0037] During the process of the towing rope 112 towing the connecting member 104 to move along the notch 101, the rack 102 will drive the driven gear 107 to rotate. The rotation of the driven gear 107 drives the rotating shaft 106 to rotate. The rotation of the rotating shaft 106 drives the driving gear 109 to rotate. The rotation of the driving gear 109 drives the end face gear 108 to rotate. The rotation of the end face gear 108 will drive the wire saw driving wheel 110 to rotate. During the rotation of the wire saw driving wheel 110, the wire saw 111 will be driven to operate, so as to cut the soil in the advancing direction of the wear-resistant fabric 113, so as to prevent impurities such as grass roots and plant fibers in the soil from hindering the wear-resistant fabric 113 from passing through the sampled soil in the container from below.

[0038] Working principle and working process: When sampling in the desert fringe area: S1: The staff holds the force application handle 4 and inserts the container composed of the front and rear baffle plates 1 and the left and right side plates 2 into the ground for soil sampling.

[0039] S2: When the front and rear baffles 1 and the left and right side plates 2 are inserted deep enough into the ground, the staff drives the handle 8 to rotate reciprocally.

[0040] S3: During the process of the handle rotating reciprocally, due to the one-way transmission structure formed by the cooperation of the ratchet 6 and the driving pawl 9, the ratchet 6 continuously rotates in one direction. During the one-way rotation of the ratchet 6, it drives the winding disc 5 to rotate synchronously. During the rotation of the winding disc 5, the towing rope 112 is wound up.

[0041] S4: During the winding process of the towing rope 112, it moves along the inner wall of the notch 101. Under the pulling force of the towing rope 112, the wear-resistant fabric 113 on the connecting piece 104 first moves down along the notch 101. After the wear-resistant fabric 113 moves to the bottom end of the notch 101, the wear-resistant fabric 113 will move horizontally under the pulling force of the towing rope 112. At this time, the wear-resistant fabric 113 penetrates the soil horizontally from the bottom and closes the opening at the bottom of the container to prevent the soil inside the container from falling when the container is pulled out upward.

[0042] Under the elastic force of the compression spring 119, the wedge-shaped clamping block 105 is located inside the limiting groove 116, so that the turntable 115 is limited within a certain external force range, thereby preventing the winding shaft 114 from rotating accidentally and causing the stretching length of the wear-resistant fabric 113 to exceed the required value.

[0043] S5: To prevent the wear-resistant fabric 113 from being blocked by grass roots and other plant fibers in the soil and stopping moving during the movement, during the process of the towing rope 112 pulling the connecting piece 104 to move along the notch 101, the rack 102 drives the driven gear 107 to rotate. The rotation of the driven gear 107 drives the rotating shaft 106 to rotate. The rotation of the rotating shaft 106 drives the driving gear 109 to rotate. The rotation of the driving gear 109 drives the face gear 108 to rotate. The rotation of the face gear 108 drives the hacksaw driving wheel 110 to rotate. During the rotation of the hacksaw driving wheel 110, it drives the hacksaw 111 to operate, thereby cutting the soil in the advancing direction of the wear-resistant fabric 113 to prevent impurities such as grass roots and plant fibers in the soil from blocking the work of the wear-resistant fabric 113 from penetrating the soil.

[0044] Compared with the prior art, the soil exploration and sampling device provided by the present invention has been improved for the problem of difficult sampling in desertified areas. The container required for sampling is formed by the front and rear baffles 1 and the left and right side plates 2. The sampling soil is cut off by the movement of the wear-resistant fabric 113 on the front and rear baffles 1 and the bottom of the container is closed to prevent the soil sample inside the container from falling when the container is pulled out upward.

[0045] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
