DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Embodiment 1, as Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, a soil sampling and detection device for fruit planting includes a cart 1, a through slot 11 is opened at the bottom end of the cart 1, a sampling component 2 is arranged at the upper end of the cart 1, a rotating component 3 is arranged on the left side of the sampling component 2, a moving component 4 is arranged on the left side of the sampling component 2, a pushing component 5 is arranged on the lower side of the sampling component 2, an adjusting component 6 is arranged on the right side of the sampling component 2, a cleaning component 7 is arranged at the bottom end of the adjusting component 6, and a limiting component 8 is arranged on the right side of the adjusting component 6.

[0022] Therefore, this solution achieves seamless connection between sampling and sample collection while ensuring the integrity of the soil sample through the cooperation between the sampling component 2 and the rotating component 3, the moving component 4, the pushing component 5, the adjusting component 6, and the cleaning component 7. Before sampling, the ground is cleaned by the adjusting component 6 and the cleaning component 7 to prevent debris from mixing into the soil sample and affecting the accuracy of the test results. The continuity and stability of the sampling process are improved as a whole, and the work efficiency is improved.

[0023] Embodiment 2: Based on Embodiment 1, this embodiment is to achieve a seamless connection between sampling and sample collection.

[0024] See also Figure 1-8 The sampling assembly 2 includes a support column 21 fixedly connected to the upper end of the cart 1, the upper end of the support column 21 is fixedly connected to a support plate 22, the upper end of the support plate 22 is fixedly installed with a hydraulic device 23, the output end of the hydraulic device 23 is fixedly connected to a connecting block 24, the lower end of the connecting block 24 is rotatably connected to a rotating block 25, the lower end of the rotating block 25 is fixedly connected to a rotating shaft 26, and the lower end of the rotating shaft 26 is fixedly connected to a sampling head 27.

[0025] See also Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 The rotating assembly 3 includes a connecting seat 31 fixedly connected to the left side of the outer surface of the connecting block 24, a belt transmission group 32 is fixedly connected to the outer surface of the rotating block 25, a rotating shaft 33 is fixedly connected to the inner surface of the belt transmission group 32, the upper end of the rotating shaft 33 is rotatably connected to the connecting seat 31, the lower end of the rotating shaft 33 is fixedly connected to a limiting bead 34, a base 37 is fixedly connected to the left side of the bottom end of the cart 1, the upper end of the base 37 is fixedly connected to a limiting seat 35, the inner surface of the limiting seat 35 is provided with an arc groove 36, and the outer surface of the limiting bead 34 is slidably connected to the arc groove 36.

[0026] Specifically, the belt drive group 1 32 mentioned above is composed of two pulleys and a belt, wherein the limiting bead 34 slides in the arc groove 36 to cause the rotating shaft 2 33 and the belt drive group 1 32 to rotate, thereby causing the rotating block 25, the rotating shaft 1 26 and the sampling head 27 to rotate, and in the initial state, there is a certain distance between the bottom end of the rotating shaft 2 33 and the upper end of the limiting seat 1 35, and only when the sampling head 27 descends to the through groove 11, the limiting bead 34 will contact the arc groove 36, thereby causing the sampling head 27 to rotate.

[0027] See also Figure 2 , Figure 3 , Figure 4 and Figure 6 The moving assembly 4 includes a connecting seat 2 41 fixedly connected to the upper end of the connecting seat 1 31, the upper end of the connecting seat 2 41 is fixedly connected to a connecting seat 3 42, the upper end of the cart 1 is fixedly connected to two limit seats 43, the outer surfaces of the two limit seats 43 are slidably connected to moving seats 44, the outer surfaces of the two moving seats 44 are provided with guide grooves 45, and the ends of the connecting seat 3 42 close to each other are slidably connected to the two guide grooves 45.

[0028] Furthermore, the second connection seat 41 and the third connection seat 42 are lifted and lowered together with the connection block 24 .

[0029] The two movable seats 44 are fixedly connected to a second base 46 on their adjacent sides. A sample cup 47 is disposed on the upper end of the second base 46 .

[0030] Furthermore, the guide groove 45 is composed of two vertical grooves and one inclined groove. When the connecting seat 42 moves in the inclined part of the guide groove 45, the movable seat 44 will be displaced, thereby changing the position of the sample cup 47, preventing the sampling head 27 from colliding with the sample cup 47 during the lifting process, ensuring that the sampling operation can be carried out smoothly, and avoiding damage to the device due to the conflict between the positions of the two.

[0031] See also Figure 3 and 7 The ejection assembly 5 includes two pushing blocks 51, and the sides of the two pushing blocks 51 that are away from each other are fixedly connected to the ends of the two moving seats 44 that are close to each other. Sliding grooves 52 are provided on both sides of the rotating shaft 26. The inner surfaces of the two sliding grooves 52 are slidably connected with a sliding plate 53. The lower end of the sliding plate 53 is fixedly connected with a plurality of connecting rods 54, and the lower ends of the plurality of connecting rods 54 are fixedly connected with a pushing plate 55. The outer surface of the pushing plate 55 is slidably connected to the inner surface of the sampling head 27. The lower end of the sliding plate 53 is fixedly connected with a plurality of springs 56. The plurality of springs 56 are all sleeved on the outer surfaces of the plurality of connecting rods 54. The upper end of the sliding groove 52 is movably connected to the lower ends of the two pushing blocks 51.

[0032] Furthermore, the sliding groove 52 can limit the sliding plate 53 so that the sliding plate 53 can only move up and down in the groove, and the spring 56 can support the sliding plate 53 in a normal state so that it always maintains a distance from the top of the sampling head 27.

[0033] Furthermore, when the sliding plate 53 is squeezed, the pushing plate 55 can be driven down together, thereby pushing out the sampled soil in the sampling head 27. No additional tools are needed to dig out or knock the sampling head to obtain the soil. The operation is simple and convenient, and it can ensure that the soil sample falls completely into the sample cup 47, reducing sample residue and spillage.

[0034] Then, the cart 1 is moved to the position where sampling is required, and the hydraulic device 23 is started to drive the connecting block 24, the rotating block 25 and the sampling head 27 to descend. During the descending process, the connecting seat 2 41 and the connecting seat 3 42 are lowered together. When the connecting seat 3 42 moves to the inclined part of the guide groove 45, the movable seat 44 drives the base 2 46 and the sample cup 47 to move to the left to make room for the sampling head 27. When the connecting seat 3 42 moves to the connection between the inclined part of the guide groove 45 and the vertical part on the lower side, the through groove 11 is completely exposed, and the sample cup 47 is also located on one side. At this time, when the hydraulic device 23 drives the sampling head 27 to continue to descend, the rotating shaft 2 33 will enter the limiting seat 1 35, so that the limiting bead 34 slides on the inner surface of the arc groove 36, so that the rotating shaft 2 33, the belt drive group 1 32, the rotating block 25, the rotating shaft 1 26 and the sampling head 27 rotate together, so that the sampling head 27 is smoothly inserted into the soil to be completely removed. After sampling is completed, the hydraulic device 23 is controlled to make the sampling head 27 rise. During the rising process, when the limiting bead 34 is disengaged from the arc groove 36, the connecting seat three 42 moves to the inclined part of the guide groove 45, and the moving seat 44 drives the base two 46 and the sample cup 47 to reset. When the connecting seat three 42 moves to the connection between the inclined part of the guide groove 45 and the vertical part on the upper side, the sample cup 47 is in a position perpendicular to the sampling head 27. At this time, the hydraulic device 23 drives the sampling head 27 to continue to rise, so that the sliding plate 53 conflicts with the pushing block 51, so that the sliding plate 53 will squeeze the spring 56 downward, drive the connecting rod 54 and the pushing plate 55 to move downward, so that the pushing plate 55 pushes the soil in the sampling head 27 completely, and then drops it into the sample cup 47 directly below.

[0035] Therefore, the present solution, through the cooperation of the sampling component 2, the rotating component 3 and the moving component 4, can not only allow the sampling component 2 to be smoothly inserted into the soil, avoiding excessive impact and damage to the sampling head 27 caused by forced downward pressure, ensuring the cutting effect on the soil, but also realizes the giving way and resetting of the sample cup 47 through the moving component 4, thereby improving the continuity and stability of the entire sampling process, and utilizes the cooperation of the sampling component 2 and the pushing component 5 to allow the soil in the sampling head 27 to fall smoothly into the sample cup 47, thereby protecting the integrity of the soil sample, providing high-quality samples that truly reflect the soil conditions for subsequent testing, and realizing the seamless connection between the sampling and sample collection links as a whole.

[0036] Embodiment 3: This embodiment is based on embodiments 1 and 2, and is for achieving the effect of cleaning the sampling position in advance.

[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 The adjusting component 6 includes a connecting seat 4 61 fixedly connected to the right side of the outer surface of the connecting block 24, a rack 63 is fixedly connected to the right side of the lower end of the connecting seat 4 61, a fixing block 1 64 is fixedly connected to the upper end of the trolley 1, an opening 641 is opened on the left side of the upper end of the fixing block 1 64, a rotating shaft 3 65 is rotatably connected to the left wall of the inner surface of the fixing block 1 64, a bevel gear 1 66 is fixedly connected to the right end of the rotating shaft 3 65, a belt transmission group 2 67 is fixedly connected to the outer surface of the rotating shaft 3 65, the outer surface of the belt transmission group 2 67 is movably connected to the opening 641, a rotating shaft 4 68 is fixedly connected to the side of the belt transmission group 2 67 away from the rotating shaft 3 65, a cylindrical gear 69 is fixedly connected to the left end of the rotating shaft 4 68, the outer surface of the cylindrical gear 69 is meshed with the rack 63, and the right end of the rotating shaft 4 68 is rotatably connected to a fixed plate 610.

[0038] Specifically, the belt transmission group 2 67 mentioned above is composed of two pulleys and a belt, so that the rotating shaft 3 65 rotates with the rotating shaft 4 68, and a notch is provided at the right end of the connecting seat 4 61, which will not hinder the cylindrical gear 69 when descending.

[0039] The tooth surface of bevel gear 1 66 is half, and one full rotation of bevel gear 1 66 can make the two bevel gears 2 612 rotate 180 degrees respectively, and the two bevel gears 2 612 rotate in opposite directions, thereby driving the connecting seat 5 73 and the cleaning brush 74 to swing back and forth. When the rack 63 drops to a certain position and disengages from the cylindrical gear 69, the bevel gear 1 66 stops rotating, so that the connecting seat 5 73 and the cleaning brush 74 also remain stationary. Among them, the stroke of the rack 63 and the cylindrical gear 69 is sufficient for the connecting seat 5 73 and the cleaning brush 74 to swing back and forth several times, and the situation where the connecting seat 5 73 is in the middle position when stopping will not occur.

[0040] See also Fig. 9 and Fig.10 The lower end of the fixed plate 610 is fixedly connected to the fixed block 64, and the inner surface of the fixed block 64 is rotatably connected to the rotating shaft 5 611. The outer surface of the rotating shaft 5 611 is located inside the fixed block 64 and is fixedly connected to two bevel gears 2 612. The outer surfaces of the two bevel gears 2 612 are meshed with the bevel gear 1 66.

[0041] See also Figure 8 , Fig. 9 and Fig.10 The cleaning component 7 includes a rotating shaft 6 71 which is slidably connected to the inner surface of the rotating shaft 5 611, a clamping block 711 is fixedly connected to the outer surface of the rotating shaft 6 71, a rotating seat 72 is fixedly connected to the lower end of the rotating shaft 6 71, a connecting seat 5 73 is fixedly connected to the outer surface of the rotating seat 72, and a cleaning brush 74 is provided at the lower end of the connecting seat 5 73.

[0042] Furthermore, the connecting seat 5 73 drives the cleaning brush 74 to swing back and forth, which can sweep away the fallen leaves, gravel and other debris on the ground, clean up a relatively clean sampling area, prevent these debris from mixing into the soil sample and affecting the accuracy of the test results, and also create good conditions for the sampling device to better contact the soil and smoothly enter the soil.

[0043] The clamping block 711 can enable the rotating shaft six 71 to rotate along with the rotating shaft five 611 and also to slide on the inner surface of the rotating shaft five 611 .

[0044] See also Fig.10 and Fig.11 The limiting assembly 8 includes a plurality of thread grooves 81 arranged on the upper side of the outer surface of the rotating shaft 6 71, the upper end of the fixed block 1 64 is fixedly connected with the fixed block 2 82, the upper end of the rotating shaft 6 71 is provided with a limiting column 83, the outer surface of the limiting column 83 is movably connected with the fixed block 2 82, the inner surface of the thread groove 81 is threadedly connected with a bolt 84, and the outer surface of the bolt 84 is rotatably connected with the fixed block 2 82.

[0045] Furthermore, a round block is provided at the upper end of the limiting column 83, which can limit the limiting column 83 so that even if it slides, it will not separate from the fixed block 82, and the bolt 84 can limit the height of the rotating shaft 6 71, so that it is in a suspended state, avoiding the problem of the cleaning brush 74 scraping the ground too low and causing damage when the device moves. The blocking block 711 has a certain weight. After the bolt 84 cancels the limit on the rotating shaft 6 71, the rotating shaft 6 71 will fall directly downward due to gravity, causing the cleaning brush 74 to contact the ground.

[0046] Furthermore, the height of the limiting column 83 is equal to the distance between the cleaning component 7 and the ground, and the limiting column 83 can be replaced according to the actual ground height.

[0047] Furthermore, when the hydraulic device 23 drives the connecting block 24 and the sampling head 27 to descend, the connecting seat 4 61 drives the rack 63 to descend together, so that the cylindrical gear 69 is meshed with the rack 63, thereby driving the cylindrical gear 69, the rotating shaft 4 68, the belt transmission group 2 67, the bevel gear 1 66 and the rotating shaft 3 65 to rotate together, and the bevel gear 1 66 will intermittently mesh with the two bevel gears 2 612, and the two bevel gears 2 612 rotate in opposite directions, so that the rotating shaft 5 611 drives the rotating shaft 6 71, the rotating seat 72, the connecting seat 5 73 and the cleaning brush 74 and other structures to swing left and right continuously, and the fallen leaves or gravel on the ground are swept to both sides, and when the rack 63 descends to a certain position, it will be disengaged from the cylindrical gear 69, and the connecting seat 5 73 will stop on one side, and then the sampling head 27 will slowly descend to the ground to sample the soil; After the sampling is completed, when the cart 1 is pushed away from the planting site, the limit column 83 can be manually lifted to lift the cleaning brush 74 to fit the bottom of the cart 1, and then the bolt 84 is turned to insert it into the threaded groove 81 to limit the height of the connecting seat 73.

[0048] Therefore, in this solution, through the cooperation of the sampling component 2, the adjustment component 6 and the cleaning component 7, when the sampling component 2 descends to take samples, the adjustment component 6 is used to drive the cleaning component 7 to swing back and forth in advance, so as to sweep away the fallen leaves, gravel and other debris on the ground, and clean up a relatively clean sampling area to prevent the debris from mixing into the soil sample and affecting the accuracy of the test results. At the same time, the height of the cleaning component 7 can be adjusted by the limit component 8, so that the cleaning component 7 can remain close to the bottom of the cart 1 when the device as a whole is not in use, thereby extending its service life.

[0049] It should be noted that the specific installation method of the hydraulic device 23 used in the present invention, the circuit connection method and the control method are all conventional designs, and the present invention will not elaborate on them in detail.
