DETAILED DESCRIPTION
[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0035] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present application provides an embodiment: an agricultural fertilizer sampler, comprising a sampling cylinder 1, the sampling cylinder 1 is fixedly connected with a plug 2 on the side wall, a collection assembly is arranged in the sampling cylinder 1, and an adjusting assembly is arranged on the side wall of the sampling cylinder 1; the collection assembly comprises a collection cylinder 4, the collection cylinder 4 is used for collecting fertilizer samples at different positions, the collection cylinder 4 is threadedly connected in the sampling cylinder 1, a partition 5 is rotatably connected in the collection cylinder 4, the partition 5 plays a role of isolation and closure, feed holes 3 are arranged in the sampling cylinder 1, the collection cylinder 4 and the partition 5, a fixed plate 6 is fixedly connected on the side wall of the partition 5, the fixed plate 6 is rotatably connected in the collection cylinder 4, recesses 7 are arranged on the side wall of the collection cylinder 4, a limiting column 8 is fixedly connected in the fixed plate 6, a clamping block 9 is slidably connected in the limiting column 8, the clamping block 9 is slidably connected in the recess 7, a first spring 10 is arranged in the limiting column 8, the first spring 10 is used for elastic return, one end of the first spring 10 is fixedly connected in the limiting column 8, and the other end of the first spring 10 is fixedly connected on the side wall of the clamping block 9.
[0036] When the sampler is in use, the worker holds the device and inserts it into the chemical fertilizer. The insertion block 2, as the first component to contact the chemical fertilizer, has a sharp outer shape structure, which can be more easily inserted into the chemical fertilizer pile, reducing the resistance during insertion, and ensuring the smooth start of the sampling process. At this time, chemical fertilizers of different depths will flow into the collection cylinder 4 through the feed holes 3, and the plurality of feed holes 3 are reasonably distributed at the corresponding positions of the collection cylinder 4, which can fully collect chemical fertilizer samples at different positions, thereby ensuring that the collected samples have good representativeness in terms of depth. Then rotate the fixed plate 6 to make the partition plate 5 rotate inside the collection cylinder 4. The fixed plate 6, as the driving component of the partition plate 5, can accurately drive the partition plate 5 to rotate inside the collection cylinder 4. The partition plate 5 plays a role in isolation and closure, and gradually changes the spatial structure inside the collection cylinder 4 during rotation to achieve coverage and opening control of the feed holes 3. When the fixed plate 6 rotates, the clamping block 9 is extruded into the limiting column 8 to extrude the first spring 10. The cooperation between the clamping block 9 and the recess hole 7 is the structure for realizing the fixation and unlocking of the fixed plate 6. When the clamping block 9 is extruded, it can smoothly slide in the limiting column 8 and compress the first spring 10, so that the first spring 10 stores elastic potential energy. At this time, the clamping block 9 is separated from the inside of the recess hole 7, and the locking of the fixed plate 6 is released to facilitate rotation. When the fixed plate 6 rotates to the other side of the recess hole 7, the clamping block 9 loses extrusion, and the first spring 10 rebounds to store elastic potential energy, which fixes the clamping block 9 in the recess hole 7, thereby covering the feed holes 3 on the collection cylinder 4 to prevent the chemical fertilizer from flowing out. Such a design can effectively close the collection cylinder 4 after sampling is completed, avoid leakage of the collected chemical fertilizer samples, ensure the integrity and accuracy of the samples, and facilitate subsequent transportation, storage and analysis of the samples. After that, the device is pulled out of the chemical fertilizer, completing the sampling of different depths of the chemical fertilizer. Then rotate the collection cylinder 4 to take it out of the sampling cylinder 1. The collection cylinder 4, as a storage container for chemical fertilizer samples, is connected to the sampling cylinder 1 in a rotatable and separable manner, which facilitates the separate removal of the collection cylinder 4 containing samples after sampling is completed, and facilitates further processing or transfer of the samples, improving the convenience and flexibility of the entire sampling process.

[0038] When the length of the sampler needs to be adjusted, the push plate 21 is pushed, and the push plate 21 serves as a trigger component, and the pushing action can make the rotating rod 20 connected thereto rotate, the rotating rod 20 serves as a transmission, and the rotation drives the clamping column 17 to move, the clamping column 17 slides on the side wall of the connecting rod 18 and presses the second spring 19, the second spring 19 can store elastic potential energy when being pressed, and the movement of the clamping column 17 cancels the fixing of the sliding rod 12, the sliding rod 12 serves as a main component for adjusting the length of the sampler, and can be pulled out at this time, so that the length of the sampler as a whole is changed, after the length required is adjusted, the push plate 21 is released, the second spring 19 rebounds, and the clamping column 17 is clamped into the fixing hole 13 by the elastic potential energy released by the rebound of the second spring 19, so that the sliding rod 12 is fixed, so that the length of the sampler is stabilized, the fertilizer can be conveniently sampled by the user, the rubber pad 15 is installed on the side wall of the handle 14, the rubber pad 15 can increase the friction between the handle 14 and the hands of the user, prevent mistakes from occurring due to hand slipping during operation, and can reduce the fatigue of the hands of the user to a certain extent, and the comfort and stability of operation are improved.
[0039] Working principle: when the sampler is in use, the worker holds the device and inserts it into the chemical fertilizer, the insertion block 2 first contacts the chemical fertilizer, at this time, the chemical fertilizer at different depths flows into the collecting cylinder 4 through the feeding hole 3, then rotates the fixed plate 6 to make the partition plate 5 rotate inside the collecting cylinder 4, when the fixed plate 6 rotates, the clamping block 9 is extruded into the limiting column 8 to extrude the first spring 10, and is separated from the recess hole 7, when the fixed plate 6 rotates to the recess hole 7 on the other side, the clamping block 9 loses the extrusion of the first spring 10 and rebounds to be clamped into the recess hole 7 to fix, covers the feeding hole 3 on the collecting cylinder 4, prevents the chemical fertilizer from flowing out, then the device is pulled out of the chemical fertilizer, the sampling of the chemical fertilizer at different depths is completed, then the collecting cylinder 4 is rotated to be taken out of the sampling cylinder 1.
[0040] When it is necessary to adjust the length of the sampler, the rotating rod 20 is rotated by pushing the push plate 21, the rotation of the rotating rod 20 drives the clamping column 17 to move, the clamping column 17 is extruded to the second spring 19 on the side wall of the connecting rod 18 by sliding, the movement of the clamping column 17 cancels the fixation of the sliding rod 12, the sliding rod 12 is pulled out, after adjusting to the required length, the second spring 19 rebounds to clamp the clamping column 17 into the fixed hole 13 to fix the sliding rod 12, which is convenient for the user to sample the fertilizer, the side wall of the handle 14 is provided with the rubber pad 15, the rubber pad 15 can increase the friction between the handle 14 and the hand of the user.
