Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer testing technology, specifically a device for rapidly testing the anti-caking performance of compound fertilizers. Background Technology

[0002] Compound fertilizer is a chemical fertilizer containing two or more of the main nutrients such as nitrogen, phosphorus, and potassium. It has high nutrient content, fast and long-lasting effects, few by-products, and good physical properties. It is widely used in the agricultural field and can significantly improve crop yield and quality. In order to ensure fertilizer quality, improve production efficiency, meet market demand, and prevent safety hazards during the production process, it is necessary to conduct rapid testing on the anti-caking performance of compound fertilizer.

[0003] Existing methods for rapid testing of the anti-caking performance of compound fertilizer samples involve first drying the sample to eliminate the influence of moisture on the test results, then applying pressure to the sample to simulate the pressure conditions experienced by fertilizers during storage and use, and finally sieving to detect the size and quantity of clumps. However, existing devices typically require collecting and cleaning the compound fertilizer after applying pressure before testing the next sample, resulting in low efficiency. To further improve the efficiency of compound fertilizer sample testing, this paper proposes a device for rapidly testing the anti-caking performance of compound fertilizers, eliminating the drawbacks of existing devices.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, such as Figures 1-4As shown, a device for rapidly detecting the anti-caking performance of compound fertilizer includes a base 1, a servo motor 8 installed inside the base 1, a turntable 7 fixedly connected to the output end of the servo motor 8, the turntable 7 extending through to the outside of the top of the base 1, the turntable 7 being rotatably connected to the base 1, a plurality of sample tubes 3 being equidistantly arranged on the upper surface of the turntable 7, a bracket 4 fixedly connected to the top of the base 1, the bracket 4 being rotatably connected to the turntable 7, a hydraulic push rod 6 installed at the top of the bracket 4, a pressure plate 5 fixedly connected to the output end of the hydraulic push rod 6, the pressure plate 5 being located above a sample tube 3, and a replacement mechanism for convenient replacement of compound fertilizer samples being provided on the sample tube 3;

[0034] The replacement mechanism includes: a plug-in assembly installed on the lofting cylinder 3;

[0035] The plug-in assembly is a docking plug 203 fixedly connected to the bottom end of the lofting cylinder 3. The bottom outer wall of the docking plug 203 is frustoconical, and the base 1 is slidably sleeved on the outer wall of the docking plug 203.

[0036] The mating block 203 is equipped with a positioning component;

[0037] The sample tube 3 is equipped with a feeding assembly;

[0038] In this embodiment, when in use, the sample-containing tube 3 is placed on the upper surface of the turntable 7. At this time, the docking block 203 is inserted into the interior of the turntable 7 under the drive of the sample-containing tube 3. During this process, the sample-containing tube 3 can be easily engaged and positioned by the replacement mechanism.

[0039] Then, the servo motor 8 is started to drive the turntable 7 to rotate stably. When the sample collection cylinder 3 containing the sample moves to the bottom of the pressure plate 5, the servo motor 8 is stopped and the hydraulic push rod 6 is started to push the pressure plate 5 into the interior of the sample collection cylinder 3. This can apply a certain pressure to the dried sample to simulate the pressure conditions of compound fertilizer during storage or use.

[0040] After the pressure is applied, the servo motor 8 is started to repeat the above operation. This allows multiple samples to be pressurized and tested sequentially. When the sample that has been pressurized moves back to its original position under the drive of the sample dispensing cylinder 3, the sample dispensing cylinder 3 can be pulled to separate from the turntable 7. Then, the pressurized sample can be easily and completely removed through the replacement mechanism, which effectively reduces dust and facilitates subsequent screening operations, thereby further improving the efficiency of compound fertilizer sample testing.

[0041] In one embodiment, such as Figures 2-4As shown, the positioning component includes: two positioning blocks 207 symmetrically arranged on the outside of the docking block 203. The outer walls of the two positioning blocks 207 are hemispherical. Positioning slots that match the outer walls of the positioning blocks 207 are provided at the joint position of the docking block 203 and the positioning blocks 207. A limit baffle 208 is fixedly connected to the end of the two positioning blocks 207 away from the docking block 203. The positioning blocks 207 and the limit baffle 208 are slidably connected to the turntable 7.

[0042] A reset component is provided on the limit baffle 208;

[0043] The reset component is a spring 206 located at the end of the limiting baffle 208 away from the positioning block 207. One end of the spring 206 contacts the outer wall of the limiting baffle 208, and the other end of the spring 206 contacts the inner wall of the turntable 7. Through the cooperation of the positioning component and the reset component, the sample cylinder 3 can be conveniently positioned by engaging the docking block 203.

[0044] In one embodiment, such as Figures 1-3 As shown, the feeding assembly includes: a feeding pusher plate 205 disposed inside the sample feeding cylinder 3, and two first movable slide plates 204 symmetrically fixed to the outer wall of the feeding pusher plate 205. The sample feeding cylinder 3 is provided with lifting grooves at the contact positions with the two first movable slide plates 204 for the first movable slide plates 204 to slide. The sample under pressure can be conveniently pushed to the outside of the sample feeding cylinder 3 by the feeding pusher plate 205, so that the sample can be conveniently and completely removed.

[0045] A limit component is provided on the first movable slide plate 204;

[0046] In one embodiment, such as Figure 3 As shown, the limiting component is a limiting slider 202 fixedly connected to the end of the first moving slide plate 204 away from the feeding push plate 205. The limiting slider 202 extends through to the outside of one end of the lofting cylinder 3. The limiting slider 202 is slidably connected to the lofting cylinder 3. Through the slidable connection between the limiting slider 202 and the lofting cylinder 3, the first moving slide plate 204 can be moved and limited.

[0047] A push component is provided on the first mobile skateboard 204;

[0048] In one embodiment, such as Figures 1-3As shown, the pushing component includes: a fixed plate 209 fixedly connected to the top of the first movable slide plate 204; a second movable slide plate 2010 fixedly connected to the bottom of the fixed plate 209; the second movable slide plate 2010 located outside the lofting cylinder 3; a connecting push ring 201 slidably sleeved on the outer wall of the lofting cylinder 3; the connecting push ring 201 and the second movable slide plate 2010 fixedly connected; the connecting push ring 201, the second movable slide plate 2010 and the limiting slider 202 fixedly connected; through the mutual cooperation of the connecting push ring 201, the fixed plate 209 and the second movable slide plate 2010, the first movable slide plate 204 can be moved.

[0049] The above embodiment discloses a device for rapidly detecting the anti-caking performance of compound fertilizer. In use, the sample-containing tube 3 is placed on the upper surface of the turntable 7. At this time, the docking block 203 is inserted into the interior of the turntable 7 under the action of the sample-containing tube 3. During this process, the positioning block 207 is pushed by the outer wall of the docking block 203 to slide along the inner wall of the turntable 7. At the same time, the spring 206 is compressed by the limiting baffle 208. When the lower surface of the sample-containing tube 3 contacts the upper surface of the turntable 7, the sample-containing tube 3 is rotated to drive the docking block 203 to rotate until the positioning slot moves to the end of the positioning block 207. At this time, the spring 206 pushes the limiting baffle 208 by rebounding, so that the positioning block 207 is inserted into the interior of the positioning slot. This allows for convenient locking and positioning of the sample-containing tube 3.

[0050] Then, the servo motor 8 is started to drive the turntable 7 to rotate stably. When the sample collection cylinder 3 containing the sample moves to the bottom of the pressure plate 5, the servo motor 8 is stopped and the hydraulic push rod 6 is started to push the pressure plate 5 into the interior of the sample collection cylinder 3. This can apply a certain pressure to the dried sample to simulate the pressure conditions of compound fertilizer during storage or use.

[0051] After pressure is applied, the servo motor 8 is started to repeat the above operation, so that multiple samples can be pressurized and tested sequentially. When the sample that has been pressurized moves back to its original position under the drive of the sample dispensing cylinder 3, the sample dispensing cylinder 3 can be pulled to separate from the turntable 7. Then, the connecting push ring 201 is pushed to move along the outer wall of the sample dispensing cylinder 3. At the same time, the fixed plate 209, driven by the second moving slide plate 2010 and the connecting push ring 201, drives the feeding push plate 205 to slide along the inner wall of the sample dispensing cylinder 3 through the first moving slide plate 204. At this time, the limiting slider 202 slides along the inner wall of the sample dispensing cylinder 3 under the drive of the first moving slide plate 204, the second moving slide plate 2010, and the connecting push ring 201. In this way, the pressurized sample can be easily and completely removed, which effectively reduces dust and is conducive to subsequent screening operations, thereby further improving the efficiency of compound fertilizer sample testing.

[0052] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
