AI Technical Summary
Existing soil sampling equipment requires additional energy or is time-consuming and labor-intensive when used outdoors, and is particularly inconvenient to use in clumped soils.
A soil sampler was designed with a tripod structure. The worm gear mechanism was driven by stepping on a pedal to move the screw up and down, thus realizing the labor-saving insertion and removal of the sampling tube. The outer diameter of the sampling tube was smaller than that of the screw, which facilitated replacement and maintenance.
It realizes efficient and labor-saving soil sampling without external energy, especially in agglomerated soil, which makes the operation faster and reduces manpower consumption.

Description
Technical Field
[0001] The present application relates to the technical field of sampling equipment, and in particular to a soil sample collector. Background Art
[0002] The collection of soil samples is a prerequisite for conducting soil environmental monitoring. In order to ensure that the collected monitoring samples are representative, sampling must be carried out in accordance with the principles and requirements of the sampling standards.
[0003] Except when the soil sample requirements are low and a shovel or spade can be used to directly scoop the soil, most soil samples are obtained using a soil auger. Soil auger types are divided into manual and driven types. When sampling, both types of soil auger press the drill bit barrel against the ground and drill into the soil, thereby collecting the soil sample into the drill bit barrel and achieving the sampling purpose. However, these two types of sampling auger have certain problems when used:
[0004] Driven sampling drills are divided into motor-driven and fuel-driven. The motor-driven type requires an external power supply, and the fuel-driven type requires fuel. Both types require additional energy supply. When used outdoors, they cannot be used normally when there is no energy.
[0005] The manual type does not require additional energy when used, but requires people to press hard, which is time-consuming and labor-intensive, especially in areas where the soil is clumped, and is inconvenient to use.
[0006] To this end, the present application provides a soil sampler to solve the problem that manual soil drilling is laborious to use. Utility Model Content
[0007] The purpose of this application is to solve the problems existing in the prior art and to propose a soil sample collector.

[0028] The following is a combination of the appended examples of the present application Figure 1-7 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.
[0029] In order to solve the problems existing in the prior art, this embodiment provides a soil sample collector, including a tripod 1, wherein the tripod 1 has a screw 2 installed on its axial thread, a sampling tube 4 is fixed to the bottom end of the screw 2, a worm gear 5 rotatably installed on the tripod 1 is axially slidably installed on the side wall of the screw 2, the worm gear 5 is engaged with a worm 6 rotatably installed on the tripod 1, two sets of foot pedals 7 are symmetrically provided at both ends of the worm 6, and a handle 3 is provided at the upper end of the screw 2.
[0030] Principle details of this embodiment:
[0031] A soil sample collector comprises a tripod 1, a screw 2, a sampling tube 4, a worm gear 5, a worm 6, a pedal 7 and a handle 3.
[0032] A handle 3 is mounted at the top of screw 2, and a sampling tube 4 is fixed to the bottom of screw 2. Screw 2 is threadedly mounted on the axis of tripod 1 and extends through tripod 1. A worm gear 5 meshes with a worm 6 and is rotatably mounted on tripod 1. Worm gear 5 is sleeved around screw 2, which extends through its axis and is axially connected to the worm gear 5. Two sets of pedals 7 are located at either end of worm gear 5, staggered and symmetrically arranged, like bicycle pedals.
[0033] The sampling tube 4 is a drill bit tube of a soil drill. A window is provided on the side wall of the sampling tube 4 , and a sealing plate is embedded in the window to facilitate taking out a relatively complete soil sample from the sampling tube 4 .
[0034] During use, place the tripod 1 firmly on the ground in the sampling area, hold the handle 3, and step on a pedal 7 with both feet. As the pedal 7 is continuously stepped on clockwise, the worm 6 rotates clockwise, the worm 6 drives the worm wheel 5 to rotate clockwise, and the worm wheel 5 drives the screw 2 to rotate clockwise. Since the screw 2 is threadedly connected to the tripod 1, when the screw 2 rotates clockwise, it will gradually descend and gradually drill into the soil layer, achieving the purpose of sampling. After the sampling is completed, step on the pedal 7 counterclockwise, and the worm wheel 5 and worm 6 drive the screw 2 to rotate counterclockwise. At this time, the screw 2 drives the sampling barrel 4 to rise, and the soil sample is taken out of the soil layer. Then the sample can be taken out of the sampling barrel 4.
[0035] When using this device, the operator stands on the foot pedal 7, using their own weight to keep the tripod 1 firmly on the ground. The operator then steps on the foot pedal 7 to drive the sampling tube 4 up and down to obtain samples. Compared to pressing with both hands, this method is more labor-saving and the sampling tube 4 penetrates the soil faster, thus achieving efficient and labor-saving sampling.
[0036] In a further embodiment of this solution, a specific tripod 1 structure is provided. The tripod 1 comprises two sets of vertically spaced mounting rings 101. A plurality of C-shaped supports 102 are arranged in a circular array on the sides of the two mounting rings 101. Support legs 103 are provided on the side walls of the supports 102, which are supported on the ground for stability. A worm gear 5 is rotatably mounted on opposing surfaces of the two mounting rings 101, while a worm 6 is rotatably mounted on one of the supports 102. In this embodiment, the structure of the tripod 1 is more aesthetically pleasing and meets the installation requirements of various components.
[0037] In a further embodiment of this solution, a specific structure for threaded connection between the tripod 1 and the screw rod 2 is provided: a screw sleeve 8 is fixed to the upper mounting ring 101 of the tripod 1, and the screw sleeve 8 is threadedly connected to the screw rod 2. Alternatively, the inner wall of the upper mounting ring 101 of the tripod 1 is tapped to form an internal threaded hole, and the screw rod 2 is threadedly connected to the threaded hole.
[0038] In a further embodiment of this solution, a specific rotatable mounting structure for the worm gear 5 and the worm 6 is provided: a sleeve 9 is fixed to the axis of the worm gear 5. The upper and lower ends of the sleeve 9 are rotatably mounted on opposing surfaces of two mounting rings 101, thereby achieving rotatable mounting of the worm gear 5. Sleeves 13 are rotatably mounted on both ends of the worm 6. A bridge 12 extends from the sleeve 13 and is fixed to the sidewall of a support 102, thereby completing the rotatable mounting of the worm 6. The inner annular array of the sleeve 9 includes multiple splines, and the outer wall of the screw 2 is provided with keyways corresponding to the splines, thereby achieving axial sliding engagement between the screw 2 and the worm gear 5.
[0039] In a further embodiment of this solution, since the screw 2 spirally rises and falls, in order to enable the operator to hold the handle 3 steadily, a rotating joint is provided between the mounting end of the handle 3 and the top of the screw 2, so that the handle 3 is rotatably connected to the screw 2. In this way, the rotation of the screw 2 does not affect the grip of the handle 3. Alternatively, the handle 3 can be configured as a steering wheel shape, so that the rotation of the screw 2 does not affect the grip.
[0040] In a further embodiment of this solution, a brush barrel 10 is fixed to the bottom end of the mounting ring 101 below the tripod 1. The inner wall of the brush barrel 10 is evenly distributed with a plurality of bristles, which abut against the outer wall of the screw rod 2. As the screw rod 2 rises, the bristles brush away dirt and other debris adhering to the threads and side walls of the screw rod 2, keeping the screw rod 2 clean and preventing thread blockage that could affect the movement stability of the screw rod 2.
[0041] In a further embodiment of this solution, the sampling barrel 4 is provided with a mounting handle at the top end thereof, and a plum blossom disk 11 is provided at the top end of the mounting handle. The plum blossom disk 11 is evenly distributed with multiple through holes, and the bottom end of the screw rod 2 is provided with threaded holes corresponding to the through holes. The screw rod 2 is threadedly connected through the through holes and the threaded holes to fasten the plum blossom disk 11 to the bottom end of the screw rod 2, thereby detachably mounting the sampling barrel 4 on the bottom end of the screw rod 2, making the sampling barrel 4 replaceable and repairable. The plum blossom disk 11 is completely retractable within the bottom wall of the screw rod 2.
[0042] In a further embodiment of this solution, the outer diameter of the sampling tube 4 is smaller than the outer diameter of the screw 2. In this way, the screw 2 can be removed from the tripod 1 without removing the sampling tube 4, which facilitates maintenance and replacement.
[0043] In a further embodiment of the present invention, each support frame 102 is provided with a brush, two of which are against the outer wall of the worm wheel 5 and one against the outer wall of the worm 6. The brushes are used to remove dust and debris adhering to the worm wheel 5 and worm 6, keeping the worm wheel 5 and worm 6 clean and tidy, and preventing debris from adhering to the brush and affecting the smoothness of the transmission of the worm wheel 5 and worm 6.
[0044] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and application concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
