Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a soil sampling device for planting agricultural products. Background Art

[0002] During the process of agricultural product cultivation, relevant personnel need to take samples of the soil to understand the fertility and characteristics of the soil, so as to understand what elements are lacking in the soil, so as to carry out scientific fertilization of the soil later. In the process of collecting soil samples, a soil drill is needed.

[0003] At present, the existing soil drilling structure is relatively simple. When it is actually used, the staff can first set the sampling tube vertically to the ground, and then the opening of the sampling tube is facing the ground, and then the hammer handle is hammered by a hammer-like tool to make the sampling tube slowly enter the ground. During the entire sampling process, it is difficult for the staff to always make the sampling tube vertically downward. If the sampling tube is offset, the soil sampled at different depths will not be distributed vertically, which is easy to cause errors in the sampling results. For this reason, we propose a soil sampling device for agricultural product planting to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a soil sampling device for planting agricultural products.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A soil sampling device for planting agricultural products comprises a sampling rod, the top end of the sampling rod is connected to a hammer handle, the bottom end of the sampling rod is connected to a sampling tube, and a limiting ring is sleeved on the outer side of the sampling tube, the upper side of the limiting ring is symmetrically connected to a support rod, and the top end of each support rod is connected to a moving block, and the outer wall of the sampling rod is provided with a moving groove adapted to the moving block.

[0007] Preferably, a connecting sleeve is provided on the outer side of the sampling rod, and a limiting plate is connected to the bottom end of the connecting sleeve, and a limiting mechanism is provided inside the connecting sleeve.

[0008] Preferably, the limiting mechanism comprises a limiting rod, which is inserted into the connecting sleeve, and the back of the sampling rod is provided with limiting grooves matching the limiting rod at equal intervals in the vertical direction, and the limiting rod is connected to a rectangular block on one side away from the connecting sleeve.

[0009] Preferably, a spring is connected to the inner side of the rectangular block, and the other end of the spring is fixedly connected to the connecting sleeve.

[0010] Preferably, a protective plate is connected to the bottom end of the limiting plate, and the protective plate is made of rubber material.

[0011] Preferably, scale marks are distributed on the outer side of the sampling rod, and the scale marks are located at the front side of the sampling rod.

[0012] Preferably, rubber pads are glued to the upper and lower ends of the limiting ring respectively, and anti-slip particles are evenly distributed on the outer surface of the rubber pads.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The device is provided with a limit ring and a moving block. During use, the limit ring and the moving block cooperate with each other to realize the straightening operation of the sampling tube, so that the sampling tube always keeps a vertical state during the sampling process, preventing the sampling tube from being skewed, so as to ensure the accuracy of subsequent test results.

[0015] 2. The device is provided with a connecting sleeve and a limit plate. During use, the insertion depth of the sampling tube can be limited by the setting of the limit plate to sample the soil at a specified depth. At the same time, the sampling amount can be controlled, thereby effectively improving the accuracy of the device during use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A soil sampling device for planting agricultural products includes a sampling rod 1, the top of the sampling rod 1 is connected to a hammer handle 2, the bottom of the sampling rod 1 is connected to a sampling tube 3, and a limiting ring 4 is sleeved on the outer side of the sampling tube 3. The sampling rod 1, the hammer handle 2 and the sampling tube 3 are parts of an existing soil drilling machine. The upper side of the limiting ring 4 is symmetrically connected to a support rod 5, and the top of the support rod 5 is connected to a moving block 6. The outer wall of the sampling rod 1 is provided with a moving groove 7 adapted to the moving block 6.

[0023] Further, see Figure 1 and Figure 2 It can be known that a connecting sleeve 8 is provided on the outer side of the sampling rod 1, and the bottom end of the connecting sleeve 8 is connected to a limiting plate 9, and a limiting mechanism is provided inside the connecting sleeve 8. Through the mutual cooperation of the connecting sleeve 8 and the limiting plate 9, the insertion depth of the sampling tube 3 can be controlled to sample the soil at a specified depth.

[0024] Further, see Figure 2 and Figure 3 It can be known that the limiting mechanism includes a limiting rod 10, which is inserted into the inside of the connecting sleeve 8. The back side of the sampling rod 1 is vertically equidistantly provided with limiting grooves that are compatible with the limiting rod 10. The side of the limiting rod 10 away from the connecting sleeve 8 is connected with a rectangular block 11. When in use, the height of the limiting plate 9 can be quickly adjusted by opening the limiting rod 10 and multiple groups of limiting grooves. In addition, after use, the staff can adjust the limiting plate 9 to a position abutting the support rod 5 to achieve the limitation of the limiting ring 4 to prevent the limiting ring 4 from easily sliding along the outer surface of the sampling tube 3.

[0025] Further, see Figure 3 It can be seen that a spring 12 is connected to the inner side of the rectangular block 11, and the other end of the spring 12 is fixedly connected to the connecting sleeve 8. When in use, the connection of the spring 12 can effectively prevent the limit rod 10 from being easily displaced during the insertion process, which can effectively ensure the reliability of the limit rod 10 being engaged in the limit groove of the sampling rod 1.

[0026] Further, see Figure 3 It can be known that the bottom end of the limit plate 9 is connected to a protective plate 13, and the protective plate 13 is set to a rubber material. When in use, the protective plate 13 set by the rubber material can effectively prevent the bottom end of the limit plate 9 from directly colliding with the support rod 5, so as to protect the support rod 5, thereby effectively preventing the support rod 5 from breaking.

[0027] Further, see Figure 1It can be seen that the outside of the sampling rod 1 is distributed with scale marks 14, and the scale marks 14 are located at the front position of the sampling rod 1. When in use, the setting of the scale marks 14 can facilitate the staff to quickly adjust the limit plate 9 to a suitable height without the aid of external measuring tools, thereby effectively improving the convenience of using the device.

[0028] Further, see Figure 1 and Figure 2 It can be seen that rubber pads are glued to the upper and lower ends of the limiting ring 4, and anti-slip particles are evenly distributed on the outer surface of the rubber pads. The rubber pads and anti-slip particles are not shown in the figure. The rubber pads distributed on the upper side of the limiting ring 4 can ensure the friction coefficient between the staff's soles and the limiting ring 4, which can make it convenient for the staff to step on the limiting ring 4. The rubber pads distributed on the lower side of the limiting ring 4 can effectively increase the contact area between the bottom end of the limiting ring 4 and the ground, thereby further preventing the limiting ring 4 from shifting during use.

[0029] Working principle: When the utility model is used, the staff can first move the device to the sampling point where sampling is required, and then manually pull the rectangular block 11 according to the sampling depth requirement or the sampling amount requirement, so as to drive the inner end of the limit rod 10 to be drawn out from the limit groove provided inside the sampling rod 1 to release the limit on the connecting sleeve 8, and then the staff can slide the connecting sleeve 8 and adjust the limit plate 9 to a suitable height according to the setting of the scale mark 14. After the adjustment is completed, the staff can stop pulling the rectangular block 11, so that the limit rod 10 can be restored by the elastic force of the spring 12. In this case, the staff can align the sampling tube 3 with the sampling area, and then step on the limiting ring 4 and use a hammer to hit the hammer handle 2. Through the cooperation of the moving block 6 and the moving groove 7, it can be effectively ensured that the sampling tube 3 extends vertically into the soil. In the process of inserting the sampling tube 3 downward, when the top of the support rod 5 and the protective plate 13 abut against each other, the sampling tube 3 is inserted to the specified depth. At this time, the staff can stop hammering the hammer handle 2, and then the staff can pull the sampling tube 3 out of the soil and take the collected soil sample out of the inside of the sampling tube 3. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
