Description

Technical Field

[0001] The utility model belongs to the technical field of soil sampling devices, and in particular relates to a soil sampling device. Background Art

[0002] The main purpose of agricultural technology promotion is to popularize scientific and technological achievements and practical technologies applied to planting, forestry, animal husbandry and fishery in agricultural production through experiments, demonstrations, guidance and training. In many cases, when agricultural planting is carried out, it is necessary to test the soil in this area. A soil sampling device is used for testing. When sampling, the existing soil sampling device often requires staff to press the sampling device into the soil for sampling. After the sampling is completed, the soil inside the sampling device generally becomes compact. When the staff squeezes the soil out of the sampling device again, they will encounter greater resistance and the operation is more laborious. For this reason, we propose a soil sampling device to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a soil sampling device, which uses a transparent sampling tube to sample soil when in use, and after the sampling is completed, the sample can be completely taken out using a push plug, which is easy to operate and can effectively improve the work efficiency of medical staff.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] A soil sampling device comprises two bottom plates arranged symmetrically on the left and right, a connecting column is fixedly installed on one side of the two bottom plates close to each other, a cross column is fixedly installed on the top of the two connecting columns, a slide groove is provided on one side of the two connecting columns close to each other, a connecting plate is slidably installed inside the two slide grooves, a transmission mechanism connected to the connecting plate is installed inside the right slide groove, the transmission mechanism can drive the right connecting plate to slide up and down, an assembly ring is fixedly installed on one side of the two connecting plates close to each other, a transparent sampling tube is fixedly installed on the bottom of the assembly ring, and the transparent sampling tube can be inserted into the soil for sampling;

[0006] Graduation lines are arranged around the transparent sampling tube, a connecting rod is fixedly installed at the center of the bottom of the horizontal column, a push plug matching the transparent sampling tube is fixedly installed at the lower end of the connecting rod, and the push plug facilitates pushing out the soil sample inside the transparent sampling tube.

[0007] As a preferred technical solution, an assembly plate is fixedly installed on the lower part of the two connecting columns on the side close to each other, and a cleaning ring is fixedly installed on the two assembly plates on the side close to each other. The end of the transparent sampling tube away from the assembly ring is inserted into the cleaning ring and connected to the cleaning ring.

[0008] As a preferred technical solution, the transmission mechanism includes a motor, and the upper and lower inner walls of the right slide groove are equipped with threaded rods that rotate together. The right connecting plate is threadedly connected to the threaded rod. The motor is fixedly installed on the right side of the top of the horizontal column, and the output shaft of the motor extends into the right slide groove and is transmission connected to the threaded rod.

[0009] As a preferred technical solution, locking universal wheels are symmetrically installed at the bottom of the two base plates.

[0010] When the utility model is in use, the two connecting plates drive the transparent sampling tube to move downward, so that the transparent sampling tube is inserted into the soil for soil sampling. The operation is convenient, and the insertion depth can be confirmed by the scale line, thereby improving the sampling accuracy. When taking out the sample, the transparent sampling tube is controlled to move upward so that the sample inside the transparent sampling tube can be completely pushed out by the push plug. The taking out process is simple and fast, which can effectively improve the work efficiency of the staff. A cleaning ring is provided to clean the periphery of the transparent sampling tube to prevent soil from blocking the scale line, which can further increase the sampling efficiency when multiple samplings are performed.

[0015] Base plate 1, connecting column 11, horizontal column 12, slide groove 13, connecting plate 14, assembly ring 15, transparent sampling tube 16, scale line 17, connecting rod 18, push plug 19, assembly plate 20, cleaning ring 21, motor 22, threaded rod 23, and locking universal wheel 24. DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-2As shown, a soil sampling device of the utility model comprises two bottom plates 1 symmetrically arranged on the left and right, a connecting column 11 is fixedly installed on one side of the two bottom plates 1 close to each other, a cross column 12 is fixedly installed on the top of the two connecting columns 11, a slide groove 13 is opened on one side of the two connecting columns 11 close to each other, a connecting plate 14 is slidably installed inside the two slide grooves 13, a transmission mechanism connected to the connecting plate 14 is installed inside the right slide groove 13, an assembly ring 15 is fixedly installed on one side of the two connecting plates 14 close to each other, and a transparent sampling tube 16 is fixedly installed on the bottom of the assembly ring 15;

[0018] Scale lines 17 are arranged around the transparent sampling tube 16 , a connecting rod 18 is fixedly installed at the center of the bottom of the cross column 12 , and a push plug 19 matching the transparent sampling tube 16 is fixedly installed at the lower end of the connecting rod 18 .

[0019] When it is necessary to sample the soil, the two bottom plates 1 are preferably placed on the soil surface so that the transparent sampling tube 16 is aligned with the sampling area. In the initial state, the transparent sampling tube 16 is located on the upper side of the position between the two connecting columns 11, and the push plug 19 is located inside the transparent sampling tube 16, and the periphery of the push plug 19 is in close contact with the inside of the transparent sampling tube 16. When sampling, the staff starts the transmission mechanism, and the transmission mechanism drives the two connecting plates 14 downward synchronously. The two connecting plates 14 drive the transparent sampling tube 16 to move downward until the bottom of the transparent sampling tube 16 is inserted into the soil, and with the continuous pressing of the two connecting plates 14, the transparent sampling tube 16 will continue to move downward to sample the soil. The staff can confirm the sampling depth according to the scale lines 17 set on the periphery of the transparent sampling tube 16. After the sampling is completed, the staff controls the transmission mechanism to drive the two connecting plates 14 to move upward and pull the transparent sampling tube 16 out of the soil. When the soil inside the transparent sampling tube 16 needs to be pushed out, the transparent sampling tube 16 is controlled to move upward continuously until the push plug 19 abuts against the soil inside the transparent sampling tube 16. The transparent sampling tube 16 continues to move upward, and the push plug 19 generates a downward pushing force to push the sample out of the transparent sampling tube 16 to complete the sampling operation. The operation is simple and convenient, and the soil sampling and sample pushing work can be completed quickly, which effectively improves the work efficiency of the staff.

[0020] An assembly plate 20 is fixedly installed at the lower part of the two connecting columns 11 close to each other, and a cleaning ring 21 is fixedly installed on the two assembly plates 20 close to each other. The end of the transparent sampling tube 16 away from the assembly ring 15 is inserted into the cleaning ring 21 and connected to the cleaning ring 21.

[0021] The cleaning ring 21 can tightly wrap the outer wall of the transparent sampling tube 16. When the transparent sampling tube 16 moves up and down, the cleaning ring 21 can clean the periphery of the transparent sampling tube 16 to prevent mud from adhering to the periphery of the transparent sampling tube 16 after sampling, thereby blocking the scale line 17 and affecting the staff's judgment on insertion. The sampling is more accurate, and the staff does not need to frequently wipe the periphery of the transparent sampling tube 16. When multiple samplings are performed, the work efficiency of the staff can be effectively improved.

[0022] The transmission mechanism includes a motor 22. The inner walls of the upper and lower sides of the right side slide groove 13 are equipped with a threaded rod 23 that rotates together. The right side connecting plate 14 is threadedly connected to the threaded rod 23. The motor 22 is fixedly installed on the right side of the top of the horizontal column 12. The output shaft of the motor 22 extends into the right side slide groove 13 and is transmission-connected to the threaded rod 23.

[0023] The staff can drive the threaded rod 23 to rotate forward and reverse by controlling the output shaft of the motor 22 to rotate forward and reverse, and then adjust the connecting plate 14 to move up and down. The operation is simple and convenient.

[0024] Lockable universal wheels 24 are symmetrically installed at the bottom of the two bottom plates 1; the arrangement of four lockable universal wheels 24 facilitates the adjustment of the position of the soil sampling device, making it more convenient to transfer the position.

[0025] According to the above overall description, when the utility model is in use, the two connecting plates 14 drive the transparent sampling tube 16 to move downward, so that the transparent sampling tube 16 is inserted into the soil for soil sampling. The operation is convenient, and the insertion depth can be confirmed by the scale line 17, thereby improving the sampling accuracy. When taking out the sample, the transparent sampling tube 16 is controlled to move upward, and the push plug 19 can be used to completely push out the sample inside the transparent sampling tube 16. The taking-out process is simple and fast, which can effectively improve the work efficiency of the staff. A cleaning ring 21 is provided to clean the periphery of the transparent sampling tube 16 to prevent the soil from blocking the scale line 16, thereby further increasing the sampling efficiency when multiple samplings are performed.

[0026] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
