Description

Technical Field

[0001] The invention relates to the technical field of flour detection, in particular to a rapid sampling method for flour detection. Background Art

[0002] Flour is a powder made from wheat. According to the protein content in flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour. High-gluten flour: darker in color, more active and smooth, not easy to form into a ball by hand; more suitable for making bread and some puff pastry. The quality of flour raw materials has a great influence on process indicators such as flour quality and flour yield, so the raw materials are inspected before entering the factory. However, the existing grain suction pump has low work efficiency; it can only sample at different depths at the same location of the grain pile, and the sampling points are not extensive, which affects the accuracy of the sampling data. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN112504755A discloses a grain sampling device for flour processing, comprising a front gantry, a rear gantry and a slide seat, wherein a left horizontal frame and a right horizontal frame are fixedly installed before the front gantry and the rear gantry, a movable frame is slidably installed between the left horizontal frame and the right horizontal frame, a first threaded rod is passed through and threadedly connected to the left end of the movable frame, the first threaded rod is driven by a first servo motor, the first servo motor is driven and fixedly installed on the upper end of the left horizontal frame, a slide seat is slidably installed on the upper end of the movable frame along the horizontal direction, a second threaded rod is passed through and threadedly connected to the interior of the slide seat, the second threaded rod is driven by a second servo motor, and the second servo motor is fixedly installed on the upper end surface of the movable frame; the present invention can continuously transport grains from the bottom of the sampling cannula to the top, thereby facilitating the suction of the grain suction pump, and improving the sampling success rate and work efficiency; vehicles of different heights can be restricted from entering and sampling, and the operation is simple.

[0004] Although the equipment in the above document can extract flour at different depths and positions, it still has obvious defects in actual use, such as: The device itself cannot be moved, so the only way to perform deep sampling is to drive a vehicle to the bottom of the device. However, as we all know, flour is usually packed in bags and then stacked in a carriage for transportation. This method makes it impossible for the device to puncture the flour bags for sampling. Although there are vehicles that specialize in transporting bulk flour, most of the carriages of such vehicles are loaded in sealed cylinders to prevent flour from spilling or being affected by the outside world. Such sealed cylinders also cannot allow the device to take samples, which reduces the practicality of the device. Therefore, a rapid sampling device for flour testing is now designed to improve the scope of use and solve such defects. Summary of the invention

Beneficial Effects

[0016] The present invention provides a rapid sampling method for flour detection. Compared with the existing technology, it has the following beneficial effects: (1) The rapid sampling method for flour detection combines the mobile conveying mechanism and the sampling linkage mechanism. The arrangement of the two mechanisms can facilitate the movement of the device, and can also sample flour at different depths. Regardless of the depth of the sampling plug's descent, it can drive several storage boxes to be transported and docked, so that the flour after sampling can be collected and stored conveniently. The whole process does not require excessive operation by the staff, and the sampling is quick and easy, which is convenient for use.

[0017] (2) The rapid sampling method for flour detection is provided with a second conveyor belt and a first conveyor belt at the front and rear of the inner side of the linkage groove respectively, and used in conjunction with a gear plate, a second arc tooth plate and a third arc tooth plate. The arrangement of these structures can use the transverse rod to drive the second conveyor belt and the first conveyor belt to move in opposite directions when the curved frame descends, so that the empty storage box can be transported and loaded, and the loaded storage box can also be moved to the right, which will not cause confusion in the sample loading position and is convenient for staff to take.

[0018] (3) The rapid sampling method for flour detection is to install a horizontal panel between two supporting plates by using a guide slide frame, and install a toothed convex plate used in conjunction with the gear rod on the top of the horizontal panel, and use it with a curved pressure plate. The arrangement of these structures can allow the curved pressure plate to press the toothed convex plate to engage with the gear rod after the first arc toothed plate descends, and then drive the gear rod to rotate by the rotation of the front horizontal rotating rod to allow the hook panel to push the storage box to move to the bottom of the feeding tube, so as to facilitate the subsequent discharge of flour into the inner side of the storage box, and also avoid the feeding tube from causing resistance to the moving storage box when it descends.

[0019] (4) The rapid sampling method for flour detection is to install a material guide bend on one side of the sampling insert and insert the material guide bend into the inner side of the feeding tube. The arrangement of these structures can ensure that the sampling insert can still extract flour and inject it into the interior of the storage box after reaching different depths, and can prevent the interior of the sampling insert from being blocked, thereby ensuring the stability during sampling.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-11 The present invention provides a technical solution: a rapid sampling method for flour detection, which specifically comprises the following steps: S1. Equipment movement: Before use, the mobile conveying mechanism 1 is pushed to a designated position using the tires at the bottom; S2, descending sampling: after reaching the designated position, the electric telescopic rod 202 in the sampling linkage mechanism 2 is started to push the sampling insert 207 downward and insert it into the flour; S3, barrel docking: during the descent of the sampling insert 207, the material storage box 107 is pushed to the inner side of the convex guide groove 109 to dock with the hook panel 121, and the material storage box 107 is pushed to move to the left side; S4, sample loading: after the storage box 107 is moved, the motor 204 is started to allow the auger blade 209 to extract the flour and inject it into the storage box 107 from the feeding tube 210; S5. Cylinder transportation: During the descent of the sampling insert 207, the material storage boxes 107 on both sides move in opposite directions to perform loading and unloading transportation.

[0024] The above-mentioned rapid sampling method for flour detection has the following more specific steps: S1. Equipment movement: Before use, several storage boxes 107 are placed in sequence inside the limiting groove 106 at the top of the storage box 107, and then the tire at the bottom is used to push the mobile conveying mechanism 1 to the specified position; S2, descending sampling: after the equipment moves to the designated position, the electric telescopic rod 202 is started to pull the bending frame 203, the motor 204 and the sampling insert 207 to slowly descend under the limiting effect of the side sliding frame 205, and the sampling insert 207 is inserted into the corresponding depth according to the position where sampling is required; S3, barrel docking: in the initial process of the sampling insert 207 descending and not inserted into the flour, the descent of the bent frame 203 will drive the two guide sliding pressure rods 213 to descend together. First, the first arc tooth plate 216 will mesh with the gear barrel 113 and push the gear barrel 113 to rotate. When the gear barrel 113 rotates, the L-shaped tooth plate 116 will be used to allow the push plate 115 to push the first storage box 107 on the left to move to the inner side of the convex guide groove 109 under the limit of the push rod 114, and the U-shaped handle 108 will dock with the hook panel 121 during the movement. After the first arc tooth plate 216 descends to the bottom, the bent pressure plate 221 will press the tooth convex plate 123 so that the teeth at the bottom pass through the rectangular opening 125 and mesh with the gear rod 111. Finally, the support plate 126 will resist the retreat bottom plate 128 and no longer descend, and the guide sliding pressure rod 213 can continue to descend along the vertical pressure rod 214 through the elastic force of the sixth spring 220; S4, sample loading: when the two guide slide pressure rods 213 continue to descend, the third arc tooth plate 218 and the fifth spring 219 will respectively mesh with the two gear plates 110 separately, so that the transverse rod 104 will respectively drive the storage box 107 to transport counterclockwise, and the first conveyor belt 105 will rotate counterclockwise, and the counterclockwise transport of the storage box 107 will move the next empty storage box 107 forward for subsequent loading. At the same time, the front transverse rod 104 will use the belt assembly 112 to drive the gear rod 111 to rotate, so that the tooth convex plate 123 meshed with it pushes the hook panel 121 and the storage box 107 to move to the right under the limit of the guide slide frame 118 so that the storage box 107 is located under the feeding cylinder 210, and then the motor 204 starts to use the rotating rod 208 to drive the auger blade 209 to rotate to draw flour from the bottom and use the guide curved cylinder 211 and the feeding cylinder 210 to inject it into the storage box 107; S5. Barrel conveying: After the flour is loaded, the two electric telescopic rods 202 will push the curved frame 203 to drive the motor 204 and the sampling insert 207 to rise. During the rising process, since the teeth of the first arc tooth plate 216, the third arc tooth plate 218 and the second arc tooth plate 217 are arc-shaped, they will not mesh with the gear barrel 113 and the gear plate 110 and will be squeezed and retracted to the inner side of the retraction frame 215. At the same time, the curved pressure plate 221 no longer presses the tooth convex plate 123, so that the tooth convex plate 123 rises under the elastic force of the third spring 124 and is aligned with the gear rod 110. 1, at this time, the horizontal panel 119 is no longer limited, and the horizontal panel 119 is pushed by the elastic force of the second spring 120 to use the hook panel 121 to drive the storage box 107 filled with flour to move right and reset. When the electric telescopic rod 202 is lowered again to take samples at other depths, steps S2, S3 and S4 are all driven in a circular manner in sequence. After being pushed by the pushing plate 115, the empty storage box 107 enters the convex guide groove 109, which pushes the storage box 107 previously filled with the flour sample to the top of the first conveyor belt 105, and then transports it away under the rotation of the first conveyor belt 105.
