Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, and in particular to a sampling device for fertilizer production. Background Technology

[0002] In the fertilizer production process, to ensure product quality, it is necessary to sample and test fertilizer products at different stages to guarantee production quality. When sampling at some production stages, operators need to use a sampling spoon to scoop fertilizer samples for testing. However, because the sampling spoon has an open structure, it can only scoop from the surface of the fertilizer product and cannot sample deeper areas. This inevitably leads to a certain degree of randomness in the testing, affecting the accuracy of the results. To address this issue, this application proposes a fertilizer production sampling device to improve the above-mentioned problems. Utility Model Content

[0003] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides a fertilizer production sampling device. The technical solution it provides includes a long insertion rod, characterized in that the long insertion rod has a hollow structure, a sampling cone is coaxially and movably fitted at the bottom of the long insertion rod, a guide assembly is fixedly connected to the inner wall of the long insertion rod, a π-shaped bracket is coaxially and fixedly connected to the inner wall of the sampling cone, two guide sleeves are fixedly connected to the upper end of the π-shaped bracket and are symmetrically arranged about its axis and vertically slidably connected to the guide assembly, an installation sleeve is integrally and coaxially arranged at the upper end of the long insertion rod, the upper end of a drive rod is coaxially and rotatably connected to the installation sleeve, the lower end of the drive rod extends into the bottom of the long insertion rod and is integrally arranged with a drive screw, a threaded sleeve is integrally arranged on the π-shaped bracket and threadedly connected to the drive screw, a clearance groove is opened on the inner wall of the lower end of the long insertion rod, and a drive handwheel is coaxially and fixedly connected to the upper end of the drive rod.

[0004] Preferably, the guide assembly includes two sets of mounting blocks arranged symmetrically about the axis of the long insert rod. Each of the two sets of mounting blocks is fixedly connected to a guide rod arranged vertically. The guide rods correspond one-to-one with the guide sleeves and are slidably connected.

[0005] Preferably, the inner wall of the long insertion rod is fixedly connected with multiple sets of vertically distributed support rods, and each support rod is integrally arranged with a support sleeve that is slidably connected to the drive rod.

[0006] The beneficial effects of this utility model are:

[0007] 1. When using this application, the sampling cone can be inserted into the fertilizer product at different depths using a long insertion rod, which facilitates sampling of the fertilizer product at different depths, thereby enabling relatively comprehensive testing of the fertilizer product and ensuring its quality.

[0008] 2. During sampling, the sampling cone is inserted into the fertilizer product to a certain depth using a long insertion rod. The drive handwheel is then turned clockwise to rotate the drive rod, causing the drive screw, which is integrated with the drive rod, to rotate clockwise synchronously. This clockwise rotation of the drive screw drives the π-shaped bracket via a screw sleeve, causing the π-shaped bracket to move downwards along the guide assembly. As the π-shaped bracket moves downwards, the sampling cone moves downwards synchronously. As the sampling cone moves downwards, it separates from the long insertion rod, exposing its upper end. The external fertilizer product is then automatically poured into the sampling cone to complete the sampling. This application features a simple structure, ease of use, and strong practicality.

[0016] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be described in further detail.

[0017] In embodiment one, the technical solution is that, during use, the sampling cone 2 can be inserted into the fertilizer product at different depths using the long insertion rod 1, facilitating sampling at different depths and enabling relatively comprehensive testing of the fertilizer product to ensure its quality. During sampling, after the sampling cone 2 is inserted to a certain depth using the long insertion rod 1, the drive handwheel 11 is rotated clockwise to turn the drive rod 7, which is rotatably connected to the mounting sleeve 6. This causes the drive screw 8, integrally arranged with the drive rod 7, to rotate clockwise synchronously. The clockwise rotation of the drive screw 8 drives the π-shaped bracket 4 through the screw sleeve 9, causing the π-shaped bracket 4 to move downwards along the guide assembly 3. As the π-shaped bracket 4 moves downwards, the sampling cone 2 moves downwards synchronously. As the sampling cone 2 moves downwards, it separates from the long insertion rod 1, exposing the upper end of the sampling cone 2, allowing the external fertilizer product to be automatically poured into the sampling cone 2 to complete the sampling. This application has a simple structure, is easy to use, and is highly practical.

[0018] In Example 2, based on Example 1, specifically, during the sampling process, the lower end of the sampling cone 2 is a pointed tip, which facilitates its insertion into the fertilizer product to a certain depth via the long insertion rod 1. After the sampling cone 2 is inserted to the required depth, the drive rod 7 is rotated clockwise. The drive screw 8, which is integrally arranged with the lower end of the drive rod 7, will also rotate clockwise. The clockwise rotation of the drive screw 8 will drive the π-shaped bracket 4 through the screw sleeve 9. The π-shaped bracket 4 is restricted by the sliding connection between the guide sleeve 5 and the guide assembly 3. Therefore, under the driving action of the drive screw 8 and the screw sleeve 9, the π-shaped bracket 4 will move downward along the vertical rod fixedly connected to the mounting block 12. As the π-shaped bracket 4 moves downward, the sampling cone 2 will move downward synchronously. As the sampling cone 2 moves downward, it will separate from the long insertion rod 1, and the upper end of the sampling cone 2 will be exposed. Then, the external fertilizer product will be automatically poured into the sampling cone 2 to complete the sampling.

[0019] In Example 3, based on Example 2, after sampling is completed and the sample in the sampling cone 2 is released, the drive screw 8 is rotated counterclockwise by driving the handwheel 11. The counterclockwise rotation of the drive screw 8 moves the π-shaped bracket 4 upwards along the guide assembly 3 to reset, thus resetting the sampling cone 2 for the next sampling operation. The clearance groove 10 provides a certain gap between the outer wall of the sampling cone 2 and the inner wall of the long insertion rod 1, preventing fertilizer products from getting stuck and affecting the reset. The drive rod 7 has a certain length; to ensure its stability during use, multiple support rods 14 are arranged and rotatably connected to it via support sleeves 15, thus providing stable support for the drive rod 7.
