Description

Technical Field

[0001] The utility model relates to the technical field of concrete premixing, and more specifically to a sampling device, in particular to a concrete premixing sampling device. Background Art

[0002] Concrete is abbreviated as "砼". Concrete refers to an engineering composite material in which aggregate is cemented into a whole by a cementitious material. Concrete is a mixture, which is made by mixing a cementitious material, aggregate and water in proportion and forms artificial stone after hardening. Cement is a commonly used cementitious material in concrete. The concrete premixing sampling device can facilitate the sampling of cement powder.

[0003] For example, a powder sampling device in concrete production disclosed in the Chinese patent publication No. CN202083571U includes a powder cylinder, a conveying hose and a controller. The controller is fixed on the steel pipe connecting the silo. There is an outlet on this steel pipe that is connected to the outlet pipe of the controller. One end of the conveying hose is connected to the outlet pipe, and the other end leads into the powder cylinder. A film covering allowing the conveying hose to pass through is provided at the mouth of the powder cylinder. The controller can controllably clamp the conveying hose. The whole process of the powder sampling device of the utility model is completed in a sealed state, and there is no powder leakage. In addition to rapid material taking, it also has the advantages of safety, high efficiency and environmental protection. In addition, it also has the advantages of sampling at any position at any time and requiring less operating manpower.

[0004] In the existing technical solution, the powder is pumped by an air pump into the stirring structure in the mixing station. In such a technical solution, it is found in actual tests that the powder needs to pass through the inside of the air pump and then enter the stirring structure. This process is likely to cause the problem of powder blockage in the air pump, which is not conducive to improving the service life of the air pump, and the damage of the air pump is not conducive to improving the conveying efficiency. Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a concrete premixing sampling device, which can solve the problems of the existing direct extraction that is likely to cause powder blockage in the air pump, is not conducive to improving the service life of the air pump, and the damage of the air pump is not conducive to improving the conveying efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pre-mixed concrete sampling device, comprising a box and an airflow blowing assembly, wherein the airflow blowing assembly is installed on the box and includes an air pump, a rigid pipe, a sleeve, a scraper and a gear, wherein the air pump is fixedly connected to the rigid pipe, the rigid pipe is fixedly inserted through the middle part of the box, the sleeve is rotatably sleeved on the outside of the rigid pipe, and both the rigid pipe and the sleeve have through holes located in the lower part of the box. The scraper is fixedly connected to the sleeve, and a toothed ring is fixedly installed on the outside of the sleeve. The toothed ring meshes with the gear. The sleeve, the scraper, the gear and the toothed ring all rotate within the box. A servo motor is fixedly installed on the upper part of the box, and the output shaft of the servo motor is fixedly connected to the gear.

[0007] By adopting the above technical solution, powder is added to the inside of the chamber. An air pump is started to drive gas into the rigid pipe, and simultaneously a servo motor is started to drive a gear to rotate. The gear drives a gear ring to rotate, which in turn drives a sleeve to rotate. The sleeve drives a scraper to rotate, and the scraper is tangential to the side wall of the sleeve. As shown in the figure, the counterclockwise rotation of the sleeve drives the scraper to rotate counterclockwise, causing the powder inside the chamber to move centripetally. When the through-hole on the sleeve coincides with the through-hole on the rigid pipe, the powder inside the chamber is pushed by the scraper through the through-hole into the rigid pipe. Then, the rotation of the sleeve briefly seals the through-hole on the rigid pipe. Since the top and side walls of the chamber are sealed, the gas inside the rigid pipe can flow into the flexible hose. Because the air pump drives the airflow from inside the rigid pipe to the flexible hose, the powder inside the rigid pipe can be transported into the flexible hose with the airflow. The powder does not pass through the air pump, preventing the air pump from becoming clogged.

[0008] The present invention is further configured such that: a fixable spraying component is installed on the rigid pipe, the fixable spraying component being used to deliver powder to the mixing structure.

[0009] The present invention is further configured such that: the fixable spray assembly includes a hose, a nozzle, and a fixing ring; the hose is fixedly sleeved above the rigid pipe; the nozzle is fixedly sleeved at the end of the hose; the fixing ring is fixedly sleeved outside the nozzle; and a magnet is rotatably mounted on the fixing ring.

[0010] The present invention is further configured such that: a feeding pipe is fixedly installed on the top of the box body, and a top cover is installed above the feeding pipe.

[0011] The present invention is further configured such that: a bracket is fixedly fitted on the outside of the air pump, and the bracket is fixedly connected to the outer side wall of the housing.

[0012] The present invention is further configured such that sealing rings are fixedly installed on both the top and bottom of the box body, and the sealing rings are fixedly sleeved on the outside of the rigid tube.

[0013] In summary, this utility model has the following beneficial effects: it can achieve the effect of rapid conveying of powder through blowing air, solves the problem of powder clogging inside the air pump, helps to improve the service life of the air pump, and avoids the problem of reduced conveying efficiency due to air pump damage.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0021] like Figure 1-2 and Figure 4As shown, a pre-mixed concrete sampling device includes a housing 1 and an airflow blowing assembly 2. The airflow blowing assembly 2 is mounted on the housing 1 and includes an air pump 201, a rigid pipe 202, a sleeve 203, a scraper 204, and a gear 205. The air pump 201 delivers gas to the rigid pipe 202, which in turn delivers powder to the flexible hose 401. The sleeve 203 supports the scraper 204, which scrapes the powder inside the housing 1. The gear 205 meshes with a gear ring 206. The air pump 201 is fixedly connected to the rigid pipe 202, which is fixedly inserted through the middle of the housing 1. The sleeve 203 is rotatably fitted onto the rigid pipe. Externally, both the rigid tube 202 and the sleeve 203 have through holes 3 located at the lower part of the box body 1. The through holes 3 facilitate the entry of powder from inside the box body 1 into the rigid tube 202. The scraper 204 is fixedly connected to the sleeve 203. A toothed ring 206 is fixedly installed on the outside of the sleeve 203. The toothed ring 206 can mesh with the gear 205. When the toothed ring 206 meshes with the gear 205, the sleeve 203, scraper 204, gear 205 and toothed ring 206 all rotate inside the box body 1. A servo motor 207 is fixedly installed on the upper part of the outside of the box body 1. The servo motor 207 can drive the gear 205 to rotate. The output shaft of the servo motor 207 is fixedly connected to the gear 205.

[0022] Powder is added to the inside of the housing 1. The air pump 201 is activated, drawing gas into the rigid pipe 202. Simultaneously, the servo motor 207 is activated, driving the gear 205 to rotate. The gear 205 drives the gear ring 206 to rotate, which in turn drives the sleeve 203 to rotate. The sleeve 203 then drives the scraper 204 to rotate. The scraper 204 is tangential to the side wall of the sleeve 203. According to... Figure 2 As shown, the counterclockwise rotation of the sleeve 203 can drive the scraper 204 to rotate counterclockwise. The scraper 204 can drive the powder inside the box 1 to move centripetally. When the through hole 3 on the sleeve 203 coincides with the through hole 3 on the hard pipe 202, the powder inside the box 1 can be pushed by the scraper 204 through the through hole 3 into the hard pipe 202. Then, the rotation of the sleeve 203 can temporarily seal the through hole 3 on the hard pipe 202. Since the top and side walls of the box 1 are sealed structures, the gas inside the hard pipe 202 can flow to the hose 401. Since the air pump 201 drives the airflow inside the hard pipe 202 to flow to the hose 401, the powder inside the hard pipe 202 can be transported to the hose 401 with the airflow. The powder does not pass through the air pump 201, which can prevent the air pump 201 from being blocked.

[0023] like Figure 1 and Figure 3-4As shown, a fixable spraying assembly 4 is installed on the rigid tube 202. The fixable spraying assembly 4 is used to deliver powder to the mixing structure. The fixable spraying assembly 4 includes a hose 401, a nozzle 402, and a fixing ring 403. The hose 401 and the nozzle 402 can deliver powder to the inside of the mixing structure. The fixing ring 403 can support the magnet 404. The hose 401 is fixedly sleeved on the top of the rigid tube 202. The nozzle 402 is fixedly sleeved on the end of the hose 401. The fixing ring 403 is fixedly sleeved on the outside of the nozzle 402. The magnet 404 is rotatably mounted on the fixing ring 403. The magnet 404 can be attracted to the mixing structure.

[0024] By inserting the nozzle 402 into the stirring structure, the magnet 404 is attracted to the side wall of the stirring structure. The magnet 404 is fixed to the stirring structure, and the nozzle 402 can be fixed inside the stirring structure by the fixing ring 403. The powder inside the rigid tube 202 enters the flexible tube 401, the powder inside the flexible tube 401 can enter the nozzle 402, and the powder inside the nozzle 402 can enter the stirring structure. By rotating the magnet 404, the angle of the magnet 404 can be adjusted, which is convenient for use with the side wall of the stirring structure in different directions.

[0025] like Figure 1 and Figure 4 As shown, a feeding pipe 5 is fixedly installed on the top of the box 1. The feeding pipe 5 can be connected to the feeding device. A top cover 6 is installed above the feeding pipe 5. Opening the top cover 6 connects the feeding pipe 5 to the feeding structure. The feeding structure can deliver powder to the inside of the box 1 through the feeding pipe 5. Covering the top cover 6 can seal the top of the feeding pipe 5 and prevent air leakage from the top of the box 1.

[0026] like Figure 1 and Figure 4 As shown, the air pump 201 is externally fixed with a bracket 7, which can fix the air pump 201. The bracket 7 is fixedly connected to the external side wall of the housing 1.

[0027] like Figure 1 and Figure 4 As shown, sealing rings 8 are fixedly installed on both the top and bottom of the housing 1. The sealing rings 8 can improve the sealing of the connection between the rigid pipe 202 and the housing 1, and prevent air leakage at the connection between the rigid pipe 202 and the housing 1, which would prevent the powder from entering the hose 401 along the rigid pipe 202. The sealing rings 8 are fixedly sleeved on the outside of the rigid pipe 202.
