Description

Technical Field

[0001] The utility model relates to the technical field related to sampling, in particular to a substrate cultivation sampling device. Background Art

[0002] When using the substrate for plant cultivation operations, in order to ensure that the substrate meets the requirements of plant cultivation, the substrate will be sampled and inspected. There is currently a substrate cultivation sampling device (application number: 202220643410.8). When sampling, the push plate is used to make the movable rod drive the discharge plate to move backward, and the sampling barrel is inserted into the substrate to be sampled, so that the substrate to be sampled enters the sampling barrel. When the staff pushes the push plate, the movable rod drives the discharge plate to move, so that the discharge plate discharges the material inside the sampling barrel, so that the staff can take out the sampled substrate more conveniently, simply and quickly.

[0003] As mentioned above, when performing matrix sampling operation, because the sampling tube as a whole penetrates into the matrix, the top of the matrix and all the matrices that have penetrated to the maximum depth will be sampled. Although the sampling work can be completed, if independent sampling operations at different depths are performed, the entire matrix sample needs to be taken out and additional segmentation operations need to be performed before the matrix sample detection operations at different depths can be performed, which will increase the total time of matrix sampling and detection, and is relatively time-consuming. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a substrate cultivation sampling device.

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

[0006] A substrate cultivation sampling device comprises a shell, a rod body is slidably connected to the shell, the rod body is rotatably connected to a connecting rod via a connecting shaft, the connecting rod is rotatably connected to a curved plate via a connecting shaft, both ends of the curved plate pass through the shell, a sampling tube is fixedly connected to the shell, and a tension spring is installed between the rod body and the shell.

[0007] Preferably, a second handle is fixedly connected to the shell, a first handle is fixedly connected to the rod body, a slide rail is fixedly connected to the second handle, and the slide rail is slidably connected to a sleeve.

[0008] Preferably, a cone is fixedly connected to the bottom end of the shell.

[0011] Preferably, two groups of round rods are fixedly connected to the shell, and the two groups of round rods are slidably connected to the curved plate.

[0012] Preferably, a rubber pad is fixedly connected to the sleeve body.

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

[0014] 1. Through the cooperation among the shell, rod, connecting rod, curved plate, sampling tube and tension spring, when the shell and the sampling tube penetrate into the matrix, because both ends of the sampling tube are open, after the sampling tube penetrates into the matrix at different depths, the matrix above will not be stored in the sampling tube, and the matrix of the corresponding depth will be retained in it. At this time, the connecting rod is driven by the downward pressure of the rod to move the curved plate into the sampling tube, and the top and bottom ends of the sampling tube will be blocked by the curved plate, and the matrix of the corresponding depth will be retained in the sampling tube. The sampling operation of the matrix of the corresponding depth can be completed by pulling out the whole tube, which can facilitate the separate sampling operation of the matrix of different depths, relatively reduce the total time of matrix sampling detection, and relatively save time;

[0015] 2. Through the cooperation between the first handle, the sleeve, the slide rail and the second handle, when the first handle drives the vertical rod to press down and moves the curved plate out of the way to block the top and bottom of the sampling tube, the sleeve can be moved laterally at the slide rail, and the sleeve can contact the first handle and limit the upward movement of the first handle. At this time, the baffle can stably block the top and bottom of the sampling tube, making it convenient to remove the matrix sample and store and carry it for a certain period of time.

[0022] 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.

[0023] Example 1, reference Figures 1 to 5 A substrate cultivation sampling device comprises a shell 1, a rod body 2 is slidably connected to the shell 1, the rod body 2 can be lifted and slid at the shell 1, the rod body 2 is connected to a connecting rod 3 by rotating through a connecting shaft, the rod body 2 can drive the connecting rod 3 to move synchronously when lifting and lowering, the connecting rod 3 is connected to a curved plate 4 by rotating through a connecting shaft, when the rod body 2 moves downward, the connecting rod 3 can be driven to move the curved plate 4 into a sampling tube 5, and the curved plate 4 can block the top and bottom ends of the sampling tube 5, and when the rod body 2 moves upward, the connecting rod 3 can be driven to move the curved plate 4 into the shell 1, so that the curved plate 4 can be taken. To eliminate the blocking operation on the top and bottom of the sampling tube 5, both ends of the curved plate 4 pass through the shell 1, and the sampling tube 5 is fixedly connected to the shell 1. A tension spring 16 is installed between the rod body 2 and the shell 1. The tension spring 16 is used to pull the downward-moving rod body 2 upward. When the sampling tube 5 moves to the specified matrix sampling depth, the curved plate 4 can block the top and bottom of the sampling tube 5 by utilizing the downward movement of the rod body 2. The matrix of the corresponding depth will be retained in the sampling tube 5, which can facilitate the separate sampling operation of the matrix at different depths, relatively reduce the total time of matrix sampling detection, and save time.

[0024] In this embodiment, a second handle 7 is fixedly connected to the shell 1, and the second handle 7 is used to drive the whole to penetrate into the matrix. A first handle 6 is fixedly connected to the rod body 2, and the first handle 6 can drive the rod body 2 to move up and down. A slide rail 8 is fixedly connected to the second handle 7, and the slide rail 8 is slidably connected to a sleeve 9, and the sleeve 9 can slide laterally at the slide rail 8. Then, when the first handle 6 moves down, the sleeve 9 can contact the first handle 6, thereby limiting the force of the first handle 6 to drive the rod body 2 to move upward, and the curved plate 4 can stably block the top and bottom ends of the sampling tube 5, so that the matrix can be trapped in the sampling tube 5. A cone 13 is fixedly connected to the bottom end of the shell 1, and the bottom of the sampling tube 5 A blade 12 is processed at the end, and the cone 13 and the blade 12 can help the shell 1 and the sampling tube 5 to penetrate into the matrix. A cover body 10 is installed on the shell 1. When the cover body 10 is separated from the shell 1, maintenance and other operations can be performed inside the shell 1. A handle 11 is fixedly connected to the cover body 10, and the handle 11 is used to drive the cover body 10 to move. Two groups of round rods 14 are fixedly connected to the shell 1, and the two groups of round rods 14 are slidably connected to the curved plate 4. The round rods 14 can guide the lateral movement of the curved plate 4. A rubber pad 15 is fixedly connected to the sleeve body 9, and the rubber pad 15 is used to increase the contact friction between the sleeve body 9 and the first handle 6, so as to ensure the stability of the upward limit of the first handle 6.

[0025] The working principle of this embodiment is as follows: when in use, the cone 13 and one end of the blade 12 are inserted into the matrix, and the second handle 7 is moved downward. The shell 1 and the sampling tube 5 will penetrate deep into the matrix with the help of the cone 13 and the blade 12. After penetrating deep into the matrix, the first handle 6 drives the rod body 2 to be pressed down, and the rod body 2 can pull the connecting rod 3 to move the curved plate 4 into the sampling tube 5. The curved plate 4 will cover the top end and the top opening of the sampling tube 5, and the matrix placed in the sampling tube 5 will be stored separately. The sleeve body 9 is moved laterally at the slide rail 8 and contacts the first handle 6, so that the tension spring 16 can be limited to drive the rod body 2 to move upward, and the curved plate 4 can be retracted into the transmission in the shell 1. The whole is pulled out, which can drive the matrix sample in the sampling tube 5 to move. After moving to the designated location, the sleeve body 9 is separated from the first handle 6, and the force of the tension spring 16 will move the rod body 2 upward, and the curved plate 4 can be retracted into the shell 1, eliminating the shielding of the top and bottom ends of the sampling tube 5, and the matrix sample in the sampling tube 5 can be taken out for detection.
