Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer fermentation, and in particular to an organic fertilizer fermentation sampler. Background Technology

[0002] Organic fertilizer is a carbon-containing material mainly derived from plants and / or animals. Its main function is to provide nutrients to plants when applied to the soil. During the fermentation process, samples of the organic fertilizer in the fermentation tank need to be taken to determine whether the fermentation is complete.

[0003] When applying for this utility model, the applicant, after searching, discovered a Chinese patent that discloses "An Organic Fertilizer Fermentation Sampler," application number "CN202321521694.4." This patent describes a sampling process where, when the sampling port is opened, a sealing pressure plate is placed over it, thus sealing the port. The sampling column is then pressed down to enter the fermentation chamber, where it is fixed by a locking block. Pressing the end block further moves the sampling tube downwards, allowing sampling to be performed. Throughout the entire sampling process, the sampling port remains sealed, effectively preventing the entry of bacteria and air, and ensuring a suitable environment for organic fertilizer fermentation.

[0004] However, with this device, the sampling column needs to be moved to a designated position to engage with the mating block in order to ensure that the sampling column is fixed. But if the fermentation chamber is shallow, the sampling column cannot reach the bottom, which means that the sampling column cannot engage with the mating block. This limits the applicability of the device to sampling operations only for fermentation chambers of a specific depth. Summary of the Invention

[0005] In view of this, the present invention provides an organic fertilizer fermentation sampler, the main technical problem to be solved is that it can only perform sampling operations on fermentation boxes at a specific depth, which limits its applicability.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an organic fertilizer fermentation sampler, comprising a pressure plate, a through groove in the middle of the pressure plate, two lifting screws movably connected to the top of the pressure plate, lifting gears fixedly connected to the outer walls of the two lifting screws, a lifting rod arranged inside the through groove, a connecting plate fixedly connected to the outer wall of the lifting rod, and two connecting plates respectively threadedly connected to the two lifting screws, a bevel gear ring arranged at the top of the pressure plate, an annular groove in the inner wall of the bevel gear ring, a toothed groove in the inner wall of the annular groove, and a support plate fixedly connected to the top of the two pressure plates, a rotating shaft arranged inside the support plate, a bevel gear fixedly connected to the left end of the rotating shaft, and a handle fixedly connected to the right end of the rotating shaft.

[0007] By adopting the above technical solution, rotating the bevel gear ring can drive the two lifting gears and the lifting screws connected to them to rotate, thereby causing the two connecting plates and the lifting rod to move down, controlling the depth of the lifting rod entering the fermentation box, which can be applied to fermentation boxes of different depths.

[0008] As a further description of the above technical solution:

[0009] The outer walls of both lifting gears mesh with the tooth grooves, and the outer wall of the bevel gear meshes with the outer wall of the bevel gear ring.

[0010] By adopting the above technical solution, the two lifting gears can rotate without disengaging from the bevel gear ring.

[0011] As a further description of the above technical solution:

[0012] The lifting rod has a through rod inside, and a pressure plate is fixedly connected to the top of the through rod. A positioning rod is fixedly connected to the bottom of the pressure plate. There are multiple positioning rods, and a spring is fixedly connected to the bottom of each positioning rod. A positioning groove is opened on the top of the lifting rod, and there are multiple positioning grooves. The bottom of the spring is in contact with the bottom of the inner wall of the positioning groove.

[0013] By adopting the above technical solution, after the lifting rod moves to the designated depth, the lower pressure plate drives the positioning rod and the sampling cylinder to move down, and the organic fertilizer in the fermentation box will enter the sampling cylinder. After the pressure plate is released, due to the action of multiple springs, the sampling cylinder, the through rod and the pressure plate return to their positions.

[0014] As a further description of the above technical solution:

[0015] The bottom of the through rod is threaded with a sampling cylinder, and the tops of the two lifting screws are threaded with a stop block.

[0016] By adopting the above technical solution, when it is necessary to remove the organic fertilizer from the sampling tube, it is only necessary to separate the sampling tube from the penetrating rod by rotating it, and then rotate it to install it at the bottom of the penetrating rod.

[0017] As a further description of the above technical solution:

[0018] The pressure plate has a rotating groove on its top, and a limiting ring is fixedly connected to the bottom of the bevel gear ring. The limiting ring is located on the inner wall of the rotating groove.

[0019] By adopting the above technical solution, the bevel gear ring will not be displaced when it rotates, and the rotation process is more stable.

[0020] As a further description of the above technical solution:

[0021] The outer wall of the rotating shaft is fixedly connected with a positioning ring, and there are two positioning rings. The two positioning rings are located on both sides of the support plate. The bottom of the pressure plate is fixedly connected with an alignment ring, and a sealing gasket is provided at the bottom of the pressure plate.

[0022] By adopting the above technical solution, the two positioning rings ensure that the rotating shaft will not slide in the support plate, and the alignment ring facilitates the alignment of the pressure plate with the sampling port of the fermentation box.

[0023] By employing the above technical solution, the organic fertilizer fermentation sampler of this utility model has at least the following beneficial effects:

[0024] 1. Compared with the existing technology, this organic fertilizer fermentation sampler, before sampling, rotates the handle to drive the rotating shaft and bevel gear to rotate. Since the bevel gear meshes with the bevel gear ring, the bevel gear ring rotates. When the bevel gear ring rotates, the two lifting gears mesh with the tooth grooves opened in the inner wall of the bevel gear ring, thereby rotating the two lifting gears and the lifting screws connected to them. This causes the two connecting plates and the lifting rod to move down synchronously, which can accurately control the depth of the lifting rod into the fermentation box, thus making it suitable for fermentation boxes of different depths and improving the applicability of the device.

[0025] 2. Compared with existing technologies, this organic fertilizer fermentation sampler, after the lifting rod moves to a designated depth, pushes the pressure plate downward, causing the pressure plate, the bottom-connected through rod, and the positioning rod to move down synchronously. During this process, multiple springs are compressed, thus separating the top of the sampling cylinder from the bottom of the lifting rod. The organic fertilizer in the fermentation chamber then enters the sampling cylinder. Subsequently, the pressure plate is released, and the multiple springs rebound, returning the sampling cylinder, the positioning rod, and the pressure plate to their original positions. Then, the sampling cylinder is rotated and separated from the through rod, allowing the organic fertilizer in the sampling cylinder to be sampled. The operation process is simple and the sampling efficiency is high. An alignment ring is set at the bottom of the pressure plate. During sampling, the alignment ring is aligned with the sampling port of the fermentation chamber, and the pressure plate will not move during sampling. The sealing gasket ensures the sealing of the pressure plate after it comes into contact with the fermentation chamber. Attached Figure Description

[0035] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0036] Reference Figure 1-7 This utility model provides an organic fertilizer fermentation sampler, comprising a pressure plate 1, with a through groove 2 in the middle of the pressure plate 1. Two lifting screws 3 are movably connected to the top of the pressure plate 1, and each of the two lifting screws 3 has a stop block 20 threadedly connected to its top. Lifting gears 4 are fixedly connected to the outer walls of each of the two lifting screws 3. A lifting rod 5 is disposed inside the through groove 2, and two connecting plates 6 are fixedly connected to the outer walls of the lifting rod 5. The two connecting plates 6 are respectively connected to the two lifting screws. The rod 3 is threaded. A bevel gear ring 7 is provided on the top of the pressure plate 1. An annular groove 8 is provided on the inner wall of the bevel gear ring 7. A toothed groove 9 is provided on the inner wall of the annular groove 8. There are multiple toothed grooves 9. The outer walls of the two lifting gears 4 mesh with the toothed grooves 9. A support plate 10 is fixedly connected to the top of the two pressure plates 1. A rotating shaft 11 is provided inside the support plate 10. A bevel gear 12 is fixedly connected to the left end of the rotating shaft 11. The outer wall of the bevel gear 12 meshes with the outer wall of the bevel gear ring 7. A handle 13 is fixedly connected to the right end of the rotating shaft 11.

[0037] Rotating the handle 13 drives the shaft 11 and the bevel gear 12 to rotate. Since the bevel gear 12 meshes with the bevel gear ring 7, the bevel gear ring 7 rotates. When the bevel gear ring 7 rotates, the two lifting gears 4 mesh with the tooth grooves 9 opened on the inner wall of the bevel gear ring 7, thereby rotating the two lifting gears 4 and the lifting screws 3 connected to them, thereby causing the two connecting plates 6 and the lifting rods 5 to move down synchronously.

[0038] Furthermore, such as Figure 1 , Figure 5-6 As shown, the lifting rod 5 has a through rod 14 inside. A pressure plate 15 is fixedly connected to the top of the through rod 14, and a positioning rod 16 is fixedly connected to the bottom of the pressure plate 15. There are multiple positioning rods 16, and springs 17 are fixedly connected to the bottom of each positioning rod 16. Pushing the pressure plate 15 downward causes the pressure plate 15, the through rod 14, and the positioning rods 16 connected to the bottom to move downward synchronously. During this process, multiple springs 17 are in a compressed state. The top of the lifting rod 5 has a positioning groove 18, and the number of positioning grooves 18 is... Multiple springs 17 have their bottoms in contact with the bottom of the inner wall of the positioning groove 18. The bottom of the through rod 14 is threadedly connected to the sampling cylinder 19. During the downward movement of the through rod 14, the top of the sampling cylinder 19 separates from the bottom of the lifting rod 5, and the organic fertilizer in the fermentation box enters the sampling cylinder 19. Then, the pressure plate 15 is released, and the multiple springs 17 rebound, causing the sampling cylinder 19, the positioning rod 16, and the pressure plate 15 to return to their positions. Then, the sampling cylinder 19 is rotated and separated from the through rod 14, and the organic fertilizer in the sampling cylinder 19 can be sampled.

[0039] Furthermore, such as Figure 6-7 As shown, a rotating groove 21 is provided on the top of the pressure plate 1, and a limiting ring 22 is fixedly connected to the bottom of the bevel gear ring 7. The limiting ring 22 is located on the inner wall of the rotating groove 21, which makes the rotation process of the bevel gear ring 7 more stable.

[0040] Furthermore, such as Figure 1 and Figure 6 As shown, a positioning ring 23 is fixedly connected to the outer wall of the rotating shaft 11, and there are two positioning rings 23. The two positioning rings 23 are located on both sides of the support plate 10. An alignment ring 24 is fixedly connected to the bottom of the pressure plate 1. When sampling, the alignment ring 24 is aligned with the sampling port of the fermentation box. When sampling, the pressure plate 1 will not move. A sealing gasket 25 is provided at the bottom of the pressure plate 1. The sealing gasket 25 ensures the sealing of the pressure plate 1 after it comes into contact with the fermentation box.

[0041] Working principle: Before sampling, rotating the handle 13 drives the rotating shaft 11 and the bevel gear 12 to rotate. Since the bevel gear 12 meshes with the bevel gear ring 7, the bevel gear ring 7 rotates. When the bevel gear ring 7 rotates, the two lifting gears 4 mesh with the toothed grooves 9 on the inner wall of the bevel gear ring 7, causing the two lifting gears 4 and the lifting screws 3 connected to them to rotate. This causes the two connecting plates 6, along with the lifting rod 5, to move down synchronously, allowing precise control of the depth to which the lifting rod 5 penetrates into the fermentation tank. The lifting rod 5 moves to the indicated depth... After reaching the set depth, push the pressure plate 15 downwards, causing the pressure plate 15, the bottom-connected through rod 14, and the positioning rod 16 to move downwards simultaneously. During this process, multiple springs 17 are compressed, causing the top of the sampling cylinder 19 to separate from the bottom of the lifting rod 5. The organic fertilizer in the fermentation box will then enter the sampling cylinder 19. Afterwards, release the pressure plate 15, and the multiple springs 17 will rebound, causing the sampling cylinder 19, the positioning rod 16, and the pressure plate 15 to return to their original positions. Then, rotate the sampling cylinder 19 and the positioning rod 16 to separate them, allowing the organic fertilizer in the sampling cylinder 19 to be sampled.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
