Description

Technical Field

[0001] This utility model relates to the field of wheat flour sampling technology, specifically a wheat flour sampling device with self-rebound protection. Background Technology

[0002] Wheat flour sampling is the process of selecting a certain amount of representative samples from a whole batch of wheat flour according to the principles of representativeness, uniformity, and standardization, for testing, analysis, or evaluation of its quality, composition, or safety. This process provides a comprehensive understanding of the characteristics of wheat flour and data support for subsequent processing, use, or sales, while also helping producers improve product quality and safety. Sampling devices are frequently required in wheat flour sampling. The existing publication CN220690581U discloses a wheat sampling device for wheat flour production. This device uses a spring to reset the sampling rod, allowing each sampling slot to form a closed area with the inner wall of the sleeve. The sleeve is then pulled out, and the sampling rod is removed by rotating the extrusion plate. This allows samples to be taken from different locations within multiple sampling slots, facilitating testing and improving efficiency. However, this sampling device cannot protect the sampling slots after sampling and sample removal, allowing external contaminants to enter the sampling cylinder, significantly reducing the safety and representativeness of the sampling and negatively impacting practical use. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a self-rebounding protective wheat flour sampling device. The self-rebounding protective device enables the baffle to automatically rebound and protect the sampling trough and the sample outlet trough, thereby preventing external contaminants from entering the sampling cylinder, thus ensuring the safety and representativeness of the sampling, bringing certain advantages to practical use, and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-rebound protective wheat flour sampling device, comprising a sampling cylinder, a housing fixedly installed on the top of the sampling cylinder, sampling slots and discharging slots respectively opened on the left and right sides of the sampling cylinder, a knob provided on the front side of the housing near its top, a rotating shaft fixedly installed on the rear side of the knob, a gear fixedly connected to the other end of the rotating shaft passing through the interior of the housing, the gear being rotatably connected to the inner wall of the housing through a bearing, a toothed plate being movably meshed on the left side of the gear, a lifting plate fixedly installed at the bottom of the toothed plate, connecting rods fixedly installed on both sides of the bottom of the lifting plate, a connecting block fixedly connected to the bottom end of the connecting rod passing through the interior of the sampling cylinder, guide cylinders fixedly installed on the upper and lower sides of the connecting block, a spring fixedly installed inside the guide cylinder, a guide rod fixedly installed at one end of the spring, and a baffle fixedly connected to the other end of the guide rod passing through the guide cylinder, the baffle being in contact with the inner wall of the sampling cylinder.

[0005] Preferably, a conical block is fixedly installed at the bottom end of the sampling cylinder, and a guide groove is formed on the surface of the conical block.

[0006] Preferably, grips are fixedly installed on both sides of the housing and near its top, and the grips are covered with anti-slip sleeves.

[0007] Preferably, the top of the housing has a through groove, the top of the toothed plate extends through the through groove to the top of the housing, and the front side of the toothed plate has a scale line.

[0008] Preferably, sliders are fixedly installed on both sides of the lifting plate, and sliding grooves are fixedly installed on both sides of the inner wall of the housing. The sliders are slidably connected to and adapted to the sliding grooves.

[0009] Preferably, a sealing gasket is fixedly installed on the outer side of the baffle, and the sealing gasket is made of rubber.

[0010] Preferably, an observation groove is provided on the front side of the sampling tube, and a transparent plate is fixedly installed on the inner side of the observation groove.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: Rotating the knob drives the gear to rotate, which in turn drives the gear plate to rise and fall. The gear plate, through a lifting plate, drives the connecting rod to rise and fall, which in turn drives the guide cylinder and guide rod to rise and fall. The guide rod, in turn, drives the baffle to rise and fall, thereby controlling sampling and sample dispensing, thus improving the convenience of sampling and testing. Furthermore, after sampling and dispensing, the baffle, under the elastic action of the spring, protects the sampling and dispensing slots, preventing external contaminants from entering the sampling cylinder, thereby ensuring the safety and representativeness of the sampling.

[0019] Furthermore, a conical block 14 is fixedly installed at the bottom of the sampling cylinder 1. A guide groove is provided on the surface of the conical block 14, which can reduce the resistance of the sampling cylinder 1 when it is inserted into the flour.

[0020] Furthermore, grips 15 are fixedly installed on both sides of the housing 2 and near its top. Anti-slip sleeves 16 are fixedly fitted on the outside of the grips 15. The anti-slip sleeves 16 can increase the friction on the outside of the grips 15 and improve the comfort of grips 15.

[0021] Furthermore, a through groove is provided on the top of the housing 2, and the top of the toothed plate 7 extends through the through groove to the top of the housing 2. A scale line 17 is provided on the front side of the toothed plate 7. The operator can control the range of the baffle 13 blocking the sampling groove 3 and the sample outlet groove 4 by observing the scale line 17, thereby improving the sampling accuracy.

[0022] Example 2, please refer to Figures 1 to 4 The difference between this embodiment and embodiment 1 is that: sliders 18 are fixedly installed on both sides of the lifting plate 8, and sliding grooves 19 are fixedly installed on both sides of the inner wall of the housing 2. The sliders 18 and sliding grooves 19 are slidably connected and adapted to each other.

[0023] Working principle: When using this self-rebound protective wheat flour sampling device, the operator can hold the handle 15 and insert the sampling cylinder 1 into the flour. The operator can turn the knob 5 counterclockwise, which drives the gear 6 to rotate. The gear 6 drives the toothed plate 7 to descend, which drives the lifting plate 8 to descend. The lifting plate 8 drives the connecting rod 9 to descend, which drives the baffle 13 to descend. This allows the flour to enter the sampling cylinder 1 through the sampling groove 3. When discharging the sample, the operator can turn the knob 5 clockwise, which raises the baffle 13, allowing the flour to be discharged through the discharge groove 4. After sampling and discharge, the operator can release the knob 5. At this time, the baffle 13, under the elastic action of the spring 11, protects the sampling groove 3 and the discharge groove 4, thereby preventing external contaminants from entering the sampling cylinder 1, thus ensuring the safety and representativeness of the sampling.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
