Description

Technical Field

[0001] This utility model relates to the technical field of samplers, and in particular to a sampler structure for testing organic fertilizer. Background Technology

[0002] Organic fertilizer, primarily derived from plants and animals, is a carbon-containing material applied to the soil to provide plant nutrition. Processed from biological matter, animal and plant waste, and plant residues, it eliminates toxic and harmful substances, becoming rich in beneficial compounds. It not only provides comprehensive nutrition for crops but also has a long-lasting effect, increasing and renewing soil organic matter, promoting microbial reproduction, and improving the soil's physical, chemical, and biological properties. It is also a key nutrient source for green food production. Currently, sampling and inspection of organic fertilizer during production processes are done manually. Analysts use tube samplers to collect samples from fermentation tanks periodically or in batches. Because the organic fertilizer in the fermentation tank is in the process of fermentation, it has a certain degree of viscosity and poor flowability. When collecting the samples, the sampling tube surface easily carries a certain amount of organic fertilizer, which can easily drip onto the ground. Repeated sampling and collection can negatively impact the sampling environment.

[0003] Chinese Patent Announcement No. CN215339092U, authorized on December 28, 2021, discloses a sampler for testing organic fertilizer, including an outer tube, an inner tube, a first handle, and a second handle. The outer and inner tubes are characterized by having open upper ends and closed lower ends. The inner tube is inserted into the inner side of the outer tube, and the upper end of the inner tube extends out of the outer tube. First handles are symmetrically arranged on the upper ends of both sides of the outer tube, and second handles are symmetrically arranged on the upper ends of both sides of the inner tube. An external sampling port is opened on the lower end of one side of the outer tube, and an internal sampling port matching the external sampling port is opened on the inner tube. A control rod and a sealing section are inserted into the inner side of the inner tube, with the sealing section installed at the lower end of the control rod. The upper end of the control rod extends out of the inner tube. A positioning component is provided on one side of the outer tube, near the upper end of the outer tube. An adjustment component is provided on one side of the inner tube, located at the portion of the inner tube extending out of the outer tube. The drawback of this invention is that the sampler is prone to causing the organic fertilizer carried by the sampling tube to drip during the collection process after sampling. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing samplers, which tend to cause organic fertilizer carried by the sampling tube to drip during the collection process after sampling. It provides a sampler structure for organic fertilizer testing that can collect samples without removing the sampling tube.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sampler structure for testing organic fertilizer includes:

[0007] A sampling tube, wherein a sampling chamber is provided inside the sampling tube, an inlet is provided at the lower end of the sampling tube and communicates with the sampling chamber, and an outlet is installed at the upper end of the sampling tube and communicates with the sampling chamber.

[0008] A cap is placed at the upper end of the sampling tube and is detachably connected to the sampling tube.

[0009] An extrusion assembly, one end of which is placed inside the sampling chamber, and the other end of which is placed outside the sampling tube after passing through the cap.

[0010] The sampling chamber of the sampling tube is used to store the sample. When the sampling tube is inserted into the organic fertilizer, the organic fertilizer enters the sampling chamber through the feed port at the lower end of the sampling tube. After sampling is completed, the organic fertilizer in the sampling chamber is lifted by pulling the extrusion component. Since the upper end of the sampling chamber is sealed by a cap, the organic fertilizer is output from the processing outlet pipe at the upper end of the sampling tube. The organic fertilizer is collected, and the sampling process is completed. If sampling is required again, the organic fertilizer can be extruded again by using the extrusion component after the sampling tube is in the position of the organic fertilizer. Moreover, the sampling tube can be cleaned by removing the cap, which achieves the purpose of collecting samples without removing the sampling tube.

[0011] Preferably, the sampling chamber is open at the upper end of the sampling tube, the cap is placed at one end of the sampling chamber opening, a drill block is installed at the lower end of the sampling tube, the drill block is conical in shape, and a handle is installed at the upper end of the sampling tube. Because the sampling chamber is open at the upper end of the sampling tube, the upper end of the sampling chamber is sealed by the cap. When inserting the sampling tube into the organic fertilizer, due to the high viscosity of the organic fertilizer, a drill block is installed at the bottom of the sampling tube. The conical drill block can better guide the sampling tube into the organic fertilizer. Furthermore, the handle at the upper end of the sampling tube allows for easy pressure application by holding the sampling tube. This design facilitates the insertion of the sampling tube into the organic fertilizer.

[0012] Preferably, the sampling tube is equipped with a pusher plate, which corresponds to the inlet. One end of the pusher plate is connected to the sampling tube above the inlet, and the angle between the pusher plate and the sampling tube is acute. Baffles are installed on both sides of the pusher plate, with one end connected to the pusher plate and the other end connected to the sampling tube. The pusher plate is installed at the inlet position on the sampling tube, forming a certain angle with the sampling tube. Because the pusher plate is installed at an angle, when the lower end of the sampling tube is inserted into the organic fertilizer, the pusher plate can push more organic fertilizer into the inlet and into the sampling chamber. Furthermore, to prevent material overflow during the pushing process, baffles are installed on both sides of the pusher plate to restrict the flow, ensuring that the material can enter the sampling chamber more effectively. This design can accelerate material collection.

[0013] Preferably, the extrusion assembly includes an extrusion block and a pull rod. The extrusion block is placed inside and matches the sampling chamber, and is slidably connected to the sampling tube. One end of the pull rod is connected to the extrusion block, and the other end of the pull rod passes through the cap and is placed outside the sampling chamber. A rotating rod is installed at the end of the pull rod that passes through the cap. The extrusion block of the extrusion assembly is placed at the bottom of the sampling chamber. After collection is completed in the sampling chamber, the pull rod is raised by the rotating rod at the top of the pull rod. Then, the pull rod raises the extrusion block, which in turn raises the organic fertilizer in the sampling chamber until it is extruded from the discharge tube, thus completing the collection of organic fertilizer. This design can extrude organic fertilizer from the sampling chamber.

[0014] Preferably, a spiral blade is installed at the end of the pull rod near the extrusion block, and the spiral blade is spiral-shaped. When the material in the sampling chamber is highly viscous and difficult to pull the extrusion block upwards, the spiral blade can be rotated by rotating the pull rod. The spiral blade then rotates within the organic fertilizer to break down the viscosity of the organic fertilizer, making it easier to pull the extrusion block out. This design facilitates the movement of the extrusion block.

[0015] Preferably, a scraper ring is installed at the end of the cover facing the sampling chamber. The scraper ring is frustoconical in shape, and the pull rod passes through the scraper ring. One end of the scraper ring is connected to the cover, and the other end of the scraper ring is attached to the pull rod. During the pulling of the pull rod, organic fertilizer may be carried out. To ensure the pull rod remains clean, a scraper ring is installed inside the cover. The scraper ring is made of elastic material, with one end connected to the cover and the other end attached to the surface of the pull rod. The surface covering the pull rod scrapes the material as the pull rod rises, thus cleaning the surface of the pull rod before it is pulled out of the sampling chamber. This design effectively cleans the surface of the pull rod.

[0016] Preferably, the sampling tube is provided with an observation hole, and an observation plate is provided inside the observation hole. The observation plate corresponds to the observation hole and is connected to the sampling tube. By opening an observation hole on the sampling tube and sealing it with an observation plate, the state of the organic fertilizer inside the sampling chamber can be observed through the transparent observation plate. This design allows for observation of the interior of the sampling chamber.

[0017] The beneficial effects of this utility model are: it can collect samples without removing the sampling tube, facilitates the insertion of the sampling tube into the organic fertilizer, can speed up the collection of materials, can squeeze out the organic fertilizer in the sampling chamber, facilitates the movement of the extrusion block, can clean the surface of the pull rod, and can observe the inside of the sampling chamber.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 , Figure 2 In the illustrated embodiment, a sampler structure for detecting organic fertilizer includes:

[0026] Sampling tube 1, sampling tube 1 is provided with sampling chamber 11, the lower end of sampling tube 1 is provided with inlet 12 and communicates with sampling chamber 11, and the upper end of sampling tube 1 is provided with outlet pipe 13 and communicates with sampling chamber 11.

[0027] Cap 2 is placed at the upper end of sampling tube 1 and is detachably connected to sampling tube 1;

[0028] The extrusion assembly 3 has one end placed inside the sampling chamber 11, and the other end of the extrusion assembly 3 passes through the cap 2 and is placed outside the sampling tube 1.

[0029] like Figure 3 As shown, the sampling chamber 11 is open at the upper end of the sampling tube 1, the cap 2 is placed at one end of the opening of the sampling chamber 11, the lower end of the sampling tube 1 is equipped with a drill block 14, the drill block 14 is conical in shape, and the upper end of the sampling tube 1 is equipped with a handle 15.

[0030] The sampling tube 1 is equipped with a pusher plate 16, which corresponds to the feed inlet 12. One end of the pusher plate 16 is connected to the sampling tube 1 above the feed inlet 12. The angle between the pusher plate 16 and the sampling tube 1 is an acute angle. Both sides of the pusher plate 16 are equipped with baffles 17. One end of the baffle 17 is connected to the pusher plate 16, and the other end of the baffle 17 is connected to the sampling tube 1.

[0031] like Figure 4 As shown, the extrusion assembly 3 includes an extrusion block 31 and a pull rod 32. The extrusion block 31 is placed inside the sampling chamber 11 and matches the sampling chamber 11. The extrusion block 31 is slidably connected to the sampling tube 1. One end of the pull rod 32 is connected to the extrusion block 31. The other end of the pull rod 32 passes through the cap 2 and is placed outside the sampling chamber 11. A rotating rod 34 is installed at the end of the pull rod 32 that passes through the cap 2.

[0032] A spiral blade 34 is installed at one end of the pull rod 32 near the extrusion block 31. The spiral blade 34 is spiral in shape.

[0033] like Figure 5 As shown, a scraper ring 21 is installed at one end of the cover 2 facing the sampling chamber 11. The scraper ring 21 is shaped like a frustum. The pull rod 32 passes through the scraper ring 21. One end of the scraper ring 21 is connected to the cover 2, and the other end of the scraper ring 21 is attached to the pull rod 32.

[0034] The sampling tube 1 is provided with an observation hole 18, and an observation plate 19 is provided inside the observation hole 18. The observation plate 19 corresponds to the observation hole 18 and is connected to the sampling tube 1.

[0035] When using this device for sampling, the sample is wedged into the organic fertilizer under the guidance of the drilling block 14 at the lower end of the sampling tube 1. Then, the fertilizer is pushed into the sampling tube 1 by the guide of the pusher plate 16. After the sampling chamber 11 of the sampling tube 1 has finished sampling, the rotating rod 33 is pulled to pull the pull rod out of the sampling chamber 11. During the movement of the pull rod 32, the extrusion block 31 is moved. The movement of the extrusion block 31 moves the fertilizer and squeezes the fertilizer out from the discharge pipe 13 at the upper end of the sampling tube 1, thus completing the collection of fertilizer. Then, the extrusion block 31 can be reset and the sample can be taken again by changing the position.

[0036] When fertilizer blockage is encountered during sampling, the rotating rod 33 drives the pull rod 32 to rotate, and the spiral blade 34 on the pull rod 32 rotates. The spiral blade 34 clears the blockage of fertilizer by rotating inside the fertilizer. Then, during the process of pulling out the pull rod 32, the scraper ring 21 on the cover 2 will clean the pull rod. After sampling is completed, the cover 2 can be opened to take out the extrusion component 3 for cleaning.
