Description

Technical Field

[0001] The utility model belongs to the technical field of material sampling equipment, in particular to a simple sampling device. Background Art

[0002] In many industries such as petroleum, chemical, medicine, grain, food, electricity, building materials, metallurgy and mining, product sampling is essential in the production process to effectively prevent materials from being scrapped in batches and reduce customers' economic losses.

[0003] Various sampling devices are important process equipment in system engineering. During the sampling process, it is crucial to reduce the complexity of the equipment and complete material sampling as quickly as possible. Product maintenance and disassembly are also a big problem. Utility Model Content

[0004] In order to solve the technical problem of inconvenient material sampling existing in the background technology, the purpose of the utility model is to provide a simple sampling device that can solve the above problem.

[0005] The technical solution for achieving the purpose of the utility model is: a simple sampling device, including a sampling tube, a sampling tube shell, a slider and a driving device, the sampling tube is slidably installed in the sampling tube shell, the slider is connected and installed on the sampling tube, and the driving device drives the slider to slide and push the sampling tube to slide out of the sampling tube shell.

[0006] In the present technical solution, the sampling tube is slidably arranged in the sampling tube shell, similar to a plunger structure. When the material needs to be sampled, the sampling tube shell can be docked on the outside of the material bin, and then the driving device pushes the sampling tube to slide out of the sampling tube shell and extend into the material bin through the sliding movement. The material enters from the feed port of the sampling tube and flows out from the discharge port at the other end, completing the sampling of the material. Of course, an entry port can be set on the material bin, and the end of the sampling tube shell abuts against the outside of the material bin entry port, and then the sampling tube passes through the material bin entry port and penetrates into the material bin. The present device has a simple structure, is convenient to assemble, maintain and disassemble, and has a small overall size. In actual use, the total weight of the device can be controlled at about 16 kg, and its light weight improves its convenience of use.

[0007] Furthermore, a slide groove is provided on the side wall of the sampling tube housing, and the slider slides in the slide groove. The sampling tube is exposed at the position of the slide groove, so the slider can be fixed on the sampling tube here and can be connected to an external driving device. At the same time, the slide groove limits the slider, that is, the length of the end of the sampling tube extending outside the sampling tube housing is limited, avoiding the problem of poor control after full extension.

[0008] Furthermore, the sampling tube and the sampling tube housing have the same length, and the sampling tube is completely retracted into the sampling tube housing when not in use, which protects the sampling tube, and the sampling tube will only extend out of the sampling tube housing when sampling materials.

[0009] Furthermore, a mounting bracket is provided on the side wall of the sampling tube housing, and the driving device is fixed on the mounting bracket. After the driving device is fixed, it is convenient for the driving device to drive the slider, that is, to drive the sampling tube to slide in the sampling tube housing.

[0010] Furthermore, the driving device is a cylinder, and mounting brackets for fixing the cylinder are provided at both ends of the slide groove. When the cylinder is inflated, it will drive the slider to move, driving the sampling tube to slide. The cylinder moves stably, which is suitable for smooth sampling of materials. Under the drive of the cylinder, the cooperation between the material taking tube and the material taking tube shell is similar to a pneumatic plunger structure.

[0011] Furthermore, the feed port of the sampling tube is arranged on the side wall of the end of the sampling tube and opens upward. When the sampling tube is extended into the material bin, the material will enter from the feed port opening upward due to its own gravity, and then surge to the discharge port to complete the sampling.

[0012] Furthermore, the sampling tube is arranged at an angle, and the height of the feed port of the sampling tube is higher than the height of the discharge port of the sampling tube. Such an arrangement facilitates the material to flow toward the discharge port after entering from the feed port, thereby facilitating sampling.

[0013] Furthermore, the end of the side wall of the sampling tube close to the feed port is provided with an inclined sharp portion. If the material bin has no entrance port, the inclined sharp portion can pierce the outer wall of the material bin such as a film or a soft material; the inclined sharp portion is also convenient for the sampling tube to extend into the material bin when entering, thereby reducing resistance.

[0014] Furthermore, the outer wall of the sampling tube is sleeved with a shaft sleeve, the shaft sleeve is made of PTFE, and the sampling tube and the sampling tube shell are made of stainless steel. In order to be suitable for different materials and the use strength requirements of the device, the sampling tube and the sampling tube shell are made of stainless steel, and the shaft sleeve made of PTFE on the outer wall of the sampling tube can prevent friction loss and sliding resistance between the sampling tube and the sampling tube shell.

[0015] By adopting the above technical solution, the utility model has the following beneficial effects:

[0016] (1) The sampling tube is slidably installed in the sampling tube housing, and the sliding is used to push the sliding of the sampling tube to form a simple material sampling device, which has a simple structure, is easy to assemble and disassemble, and is light in weight and easy to use, and is relatively convenient;

[0017] (2) A slide groove is provided on the sampling tube housing to facilitate fixing the slider on the sampling tube and to facilitate the driving device to drive the slider to slide. The slide groove can also play a limiting role;

[0018] (3) The sampling tube is set at an angle to facilitate the flow of materials from the feed port to the discharge port;

[0019] (4) An inclined sharp portion is provided at the feed port end of the sampling tube to facilitate the sampling tube to pierce the outer wall of the material bin without an entry port, and also to reduce resistance when entering the material bin filled with materials;

[0020] (5) A shaft sleeve made of PTFE is provided between the sampling tube and the sampling tube housing to prevent problems caused by friction between the sampling tube and the sampling tube housing, both of which are made of stainless steel. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1-Figure 3As shown, this embodiment provides a simple sampling device, including a sampling tube 1, a sampling tube housing 2, a slider 3 and a driving device, wherein the sampling tube 1 is slidably installed in the sampling tube 1 housing, the slider 3 is connected and installed on the sampling tube 1, and the driving device drives the slider 3 to slide and push the sampling tube 1 to slide out of the sampling tube housing 2. In this technical solution, the sampling tube 1 is slidably arranged in the sampling tube 1 housing, similar to the plunger structure, when the material needs to be sampled, the sampling tube housing 2 can be docked on the outside of the material bin 4, and then the driving device pushes the sampling tube 1 to slide out of the sampling tube housing 2 and extend into the material bin 4 through the sliding, and the material enters from the feed port 8 of the sampling tube 1 and flows out from the discharge port 9 at the other end, completing the sampling of the material. Of course, an entry port can be set on the material bin 4, and the end of the sampling tube housing 2 abuts against the outside of the entry port of the material bin 4, and then the sampling tube 1 passes through the entry port of the material bin 4 and penetrates into the material bin 4. The device has a simple structure, is convenient to assemble, repair and disassemble, and has a small overall size. In actual use, the total weight of the device can be controlled at about 16 kg, and its light weight improves its convenience in use.

[0028] Preferably, a slide groove 5 is provided on the side wall of the sampling tube housing 2, and the slider 3 slides in the slide groove 5. The sampling tube 1 is exposed at the position of the slide groove 5, so the slider 3 can be fixed on the sampling tube 1 here and can be connected to an external driving device. At the same time, the slide groove 5 limits the slider 3, that is, the length of the end of the sampling tube 1 extending outside the sampling tube housing 2 is limited, avoiding the problem of poor control after being fully extended.

[0029] Preferably, the sampling tube 1 and the sampling tube housing 2 have the same length, and the sampling tube 1 is completely retracted into the sampling tube housing 2 when not in use, which protects the sampling tube 1 and only extends out of the sampling tube housing 2 when sampling materials.

[0030] Preferably, a mounting bracket 6 is provided on the side wall of the sampling tube housing 2, and the driving device is fixed on the mounting bracket 6. After the driving device is fixed, it is convenient for the driving device to drive the slider 3, that is, to drive the sampling tube 1 to slide in the sampling tube housing 2. The driving device is a cylinder 7, and mounting brackets 6 for fixing the cylinder 7 are provided at both ends of the slide 5. When the cylinder 7 is inflated, the slider 3 is driven to move, and the sampling tube 1 is driven to slide. The cylinder 7 moves stably, which is suitable for stable sampling of materials; under the drive of the cylinder 7, the cooperation between the material taking tube and the material taking tube housing is similar to a pneumatic plunger structure.

[0031] Preferably, the feed port 8 of the sampling tube 1 is arranged on the side wall of the end of the sampling tube 1, and the opening is upward. When the sampling tube 1 is extended into the material bin 4, the material will enter from the feed port 8 opening upward due to its own gravity, and then flow toward the discharge port 9 to complete the sampling. The sampling tube 1 is arranged at an angle, and the height of the feed port 8 of the sampling tube 1 is higher than the height of the discharge port 9 of the sampling tube 1. Such an arrangement facilitates the material to flow toward the discharge port 9 after entering from the feed port 8, which is convenient for sampling.

[0032] Preferably, the end of the side wall of the sampling tube 1 near the feed port 8 has an inclined sharp portion 10. When the material bin 4 has no entrance, the inclined sharp portion 10 can pierce the outer wall of the material bin 4 such as a film or a soft material; the inclined sharp portion 10 is also convenient for the sampling tube 1 to extend into the material bin 4 when it enters, thereby reducing resistance.

[0033] Preferably, the outer wall of the sampling tube 1 is sleeved with a shaft sleeve 11, the shaft sleeve 11 is made of PTFE, and the sampling tube 1 and the sampling tube housing 2 are made of stainless steel. In order to be suitable for different materials and the use strength requirements of the device, the sampling tube 1 and the sampling tube housing 2 are made of stainless steel, and the shaft sleeve 11 made of PTFE is sleeved on the outer wall of the sampling tube 1 to prevent friction loss and sliding resistance between the sampling tube 1 and the sampling tube housing 2.

[0034] Working principle: when material sampling is required, the cylinder 7 is started to push the slider 3 to slide in the slide groove 5. While the slider 3 slides, the end of the sampling tube 1 is driven to extend out of the sampling tube housing 2 and extend into the material bin 4. The material enters the feed port 8 of the sampling tube 1 under the action of gravity; then, as the sampling tube 1 is tilted, the material will surge toward the discharge port 9, and finally complete the sampling of the material.
