Description

Technical Field

[0001] This utility model relates to the field of cucumber fertilization technology, and in particular to a sampling device for cucumber fertilization detection that is easy to adjust the detection depth. Background Technology

[0002] Before fertilizing the soil for cucumber cultivation, it is necessary to sample the soil in advance. During sampling, a sampler is usually used to drill into the soil to collect soil samples at a certain depth. Therefore, a sampling device for cucumber fertilization testing that is easy to adjust the detection depth is needed.

[0003] Existing sampling devices for cucumber fertilization testing use a soil drill bit to collect soil samples for testing. However, when the sampling rod is moved into the soil, the lack of a lifting mechanism makes it inconvenient for workers to pull it out, reducing work efficiency. In addition, the sampling rod tends to tilt during sampling, resulting in low sampling accuracy.

[0004] Therefore, the existing cucumber fertilization testing sampling device lacks a lifting structure for the sampling rod, making soil sampling inconvenient for staff. Furthermore, existing devices often experience sampling rod tilting, leading to reduced sampling accuracy. This invention addresses this issue by rotating the first rocker arm to move the moving block along the screw, thus controlling the sampling rod's movement. Staff can pull the limiting rod out of the limiting hole by pulling the pull plate, separating the second rocker arm from the connecting block. The measuring ruler facilitates the detection of different soil depths. Simultaneously, the double-ended threaded rod causes the two threaded blocks to move along the thread direction, ensuring the two control plates are in contact and preventing the sampling rod tilting from reducing accuracy. Utility Model Content

[0005] To overcome the problem that common sampling devices for cucumber fertilization testing lack a lifting mechanism for the sampling rod, making it inconvenient for staff to sample the soil, and that existing devices tend to tilt the sampling rod during sampling, resulting in reduced sampling accuracy.

[0006] The technical solution of this utility model is as follows: a sampling device for cucumber fertilization detection with adjustable detection depth, comprising a base; a side plate is installed on the right side of the upper end of the base, a top plate is installed on the upper end of the side plate, a lead screw is rotatably connected in the top plate, the lower end of the lead screw is rotatably connected to the base, the upper end of the lead screw extends to the upper end of the top plate, a first rocker arm is installed on the upper end of the lead screw, a moving block is threadedly connected to the surface of the first rocker arm, a connecting block is installed on the left end of the moving block, a positioning hole is opened on the surface of the base, a sampling rod is set in the positioning hole, a soil-sampling drill bit is installed on the lower end of the sampling rod, a spiral plate is installed on the surface of the sampling rod, a second rocker arm is installed on the upper end of the sampling rod, a rotating plate is rotatably connected to the surface of the sampling rod, and the rotating plate is located above the spiral plate.

[0007] Preferably, rotating seats are installed at both ends of the connecting block, and a limiting plate is rotatably connected in the rotating seat, and a limiting hole is formed on the surface of the second rocker.

[0008] Preferably, a limiting rod is slidably connected in the limiting plate, a pull plate is installed on the surface of the limiting rod, a spring is sleeved on the surface of the limiting rod, one end of the spring is fixedly connected to the pull plate, the other end of the spring is fixedly connected to the limiting plate, and the limiting rod is engaged with the limiting hole.

[0009] Preferably, a slide rail is installed at the lower end of the top plate. Two slide rails are provided, and a slider is slidably connected to the surface of the slide rail. The slider and the moving block are fixedly connected.

[0010] Preferably, a fixing plate is installed on the left side of the upper end of the base, a connecting seat is installed on the upper end of the fixing plate, a positioning groove is provided in the connecting seat, a positioning block is slidably connected in the positioning groove, a measuring ruler is provided on the surface of the connecting seat, a connecting plate is installed on the right end of the positioning block, and the connecting plate and the rotating plate are fixedly connected.

[0011] Preferably, a double-threaded rod is rotatably connected to the fixing plate. The left end of the double-threaded rod extends to the left side of the fixing plate. A third rocker arm is installed at the left end of the double-threaded rod. The threads at both ends of the double-threaded rod are opposite and have equal pitch. A baffle is rotatably connected to the right end of the double-threaded rod. The baffle is fixedly connected to the base. A guide rail is installed on the right end of the fixing plate in front of the double-threaded rod. The right end of the guide rail is fixedly connected to the baffle.

[0012] Preferably, threaded blocks are threaded to both ends of the surface of the double-ended threaded rod, and mounting blocks are installed at the front ends of the threaded blocks. Guide blocks are slidably connected to the surface of the guide rail. There are two guide blocks, and the right end of each guide block is equipped with an identical mounting block. A control plate is installed between the two mounting blocks. There are two control plates. Rollers are installed at the lower end of the base. There are four rollers.

[0013] The beneficial effects of this utility model are:

[0014] 1. When the device is in operation, the operator can rotate the first rocker arm to drive the lead screw to rotate. During the rotation of the lead screw, the moving block connected by the thread moves along the thread direction and the slider slides along the slide rail direction, so that the operator can drive the sampling rod to lift and lower. The operator can also pull the pull plate to pull the limiting rod out of the limiting hole, so that the connecting block is separated from the second rocker arm, which facilitates the operator to perform rotation sampling operation. Under the action of the connecting seat, the rotating plate drives the connecting plate to slide in the positioning groove along with the positioning block. At the same time, the sampling depth can be adjusted according to the measuring ruler.

[0015] 2. During the sampling operation, the operator can rotate the double-ended threaded rod by rotating the third rocker arm. During the rotation of the double-ended threaded rod, the threaded block connected to the thread moves along the thread direction, and simultaneously drives the guide block to slide along the guide rail. This controls the mounting block to make the two control blocks fit together, thereby limiting the sampling rod and avoiding the problem of sampling depth deviation caused by the tilting of the sampling rod, which would reduce the sampling accuracy of the device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a sampling device for cucumber fertilization detection with adjustable detection depth, including a base 1; a side plate 2 is installed on the right side of the upper end of the base 1, a top plate 3 is installed on the upper end of the side plate 2, a lead screw 4 is rotatably connected in the top plate 3, the lower end of the lead screw 4 is rotatably connected to the base 1, the upper end of the lead screw 4 extends to the upper end of the top plate 3, a first rocker arm 41 is installed on the upper end of the lead screw 4, a moving block 42 is threadedly connected to the surface of the first rocker arm 41, a connecting block 5 is installed on the left end of the moving block 42, a positioning hole 6 is opened on the surface of the base 1, a sampling rod 7 is set in the positioning hole 6, a soil sampling drill bit 71 is installed on the lower end of the sampling rod 7, a spiral plate 72 is installed on the surface of the sampling rod 7, a second rocker arm 73 is installed on the upper end of the sampling rod 7, a rotating plate 74 is rotatably connected to the surface of the sampling rod 7, and the rotating plate 74 is located above the spiral plate 72.

[0025] Rotating seats 51 are installed at both ends of the connecting block 5. A limiting plate 52 is rotatably connected in the rotating seat 51. A limiting hole 75 is opened on the surface of the second rocker arm 73. By installing rotating seats 51 at both ends of the connecting block 5, the limiting plate 52 can rotate around the rotating seat 51 as the axis, which provides convenience for fixing the sampling rod 7 later.

[0026] A limiting rod 53 is slidably connected in the limiting plate 52. A pull plate 54 is installed on the surface of the limiting rod 53. A spring 55 is sleeved on the surface of the limiting rod 53. One end of the spring 55 is fixedly connected to the pull plate 54, and the other end of the spring 55 is fixedly connected to the limiting plate 52. The limiting rod 53 is engaged with the limiting hole 75. Under the action of the spring 55, the pull plate 54 drives the limiting rod 53 to reset and insert the limiting rod 53 into the limiting hole 75, thereby achieving the disassembly and assembly operation of the sampling rod 7 and the connecting block 5.

[0027] A slide rail 43 is installed at the lower end of the top plate 3. There are two slide rails 43. A slider 44 is slidably connected to the surface of the slide rail 43. The slider 44 and the moving block 42 are fixedly connected. By setting the slide rail 43, the slider 44 slides along the direction of the slide rail 43 to realize the synchronous movement of the slider 44 and the moving block 42, thereby increasing the stability of the device.

[0028] A fixing plate 8 is installed on the left side of the upper end of the base 1. A connecting seat 81 is installed on the upper end of the fixing plate 8. A positioning groove 82 is opened in the connecting seat 81. A positioning block 83 is slidably connected in the positioning groove 82. A measuring ruler 84 is provided on the surface of the connecting seat 81. A connecting plate 85 is installed on the right end of the positioning block 83. The connecting plate 85 and the rotating plate 74 are fixedly connected. By opening the positioning groove 82, the positioning block 83 can slide in the positioning groove 82. Under the action of the measuring ruler 84, the staff can adjust the sampling rod 7 according to the depth to be detected.

[0029] A double-threaded rod 9 is rotatably connected to the fixed plate 8. The left end of the double-threaded rod 9 extends to the left side of the fixed plate 8. A third rocker arm 90 is installed at the left end of the double-threaded rod 9. The threads at both ends of the double-threaded rod 9 are opposite and have equal pitch. A baffle 91 is rotatably connected to the right end of the double-threaded rod 9. The baffle 91 is fixedly connected to the base 1. A guide rail 10 is installed on the right end of the fixed plate 8 in front of the double-threaded rod 9. The right end of the guide rail 10 is fixedly connected to the baffle 91. The operator rotates the third rocker arm 90 to drive the double-threaded rod to rotate, providing power for the subsequent limiting of the sampling rod 7.

[0030] The two ends of the double-ended threaded rod 9 are threadedly connected to threaded blocks 92. The front end of the threaded blocks 92 is equipped with an installation block 93. The surface of the guide rail 10 is slidably connected to a guide block 11. There are two guide blocks 11. The right end of the guide block 11 is equipped with the same installation block 93. There are two control plates 12 between the two installation blocks 93. The lower end of the base 1 is equipped with four rollers 13. When the double-ended threaded rod 9 rotates, it drives the threaded blocks 92 to move along the thread direction, so as to drive the control plates 12 to move closer to each other and make the two control plates 12 fit together, thereby limiting the sampling rod 7 and preventing the sampling rod 7 from tilting.

[0031] Working principle: According to Figures 1-6 When the device is in operation, the first rocker arm 41 is rotated to drive the lead screw 4 to rotate. During the rotation of the lead screw 4, the moving block 42 moves along the thread direction and simultaneously drives the slider 44 to slide along the slide rail 43. This causes the connecting block 5 to drive the second rocker arm 73 to rise and fall synchronously. When the soil sampling drill bit 71 is in contact with the ground, the operator pulls the pull plate 54 to pull the limit rod 53 out of the limit hole 75. Then, the limit plate 52 is rotated around the rotating seat 51 to separate the connecting block 5 from the second rocker arm 73. Subsequently, the second rocker arm 73 is rotated to make the soil sampling drill bit 71 drill into the soil and simultaneously drive the rotating plate 74 to rise and fall. This causes the connecting plate 85 to drive the positioning block 83 to slide in the positioning groove 82. With the help of the measuring ruler 84, it is convenient for the operator to adjust the detection depth.

[0032] according to Figure 1 , Figure 2 and Figure 4 During sampling, the operator can rotate the third rocker arm 90 to rotate the double-ended threaded rod 9. During the rotation of the double-ended threaded rod 9, the threaded block 92 connected to the thread moves along the thread direction, thereby causing the mounting block 93 to move synchronously. This causes the two control plates 12 to come into contact with each other, achieving the limiting operation of the sampling rod 7. When the threaded block 92 moves, the guide block 11 slides synchronously along the guide rail 10, which increases the stability of the device and prevents the sampling rod 7 from tilting, causing the soil sampling drill bit 71 to deviate, which would reduce the sampling accuracy of the device.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
