Description

Technical Field

[0001] The utility model belongs to the technical field of flour detection equipment, and particularly relates to a sampling device for flour detection. Background Technique

[0002] Flour is a powdery substance ground from wheat. In the process of flour processing, there are many steps. After the flour finished product is processed and enters the storage warehouse, it is necessary to conduct quality inspection on the flour. The quality inspection includes detecting indicators such as the whiteness, moisture, and ash content of the flour to ensure that the quality of the products leaving the warehouse is qualified. When detecting various indicators of flour, a flour sampling device is often used to sample the flour, so as to improve the work efficiency of sampling. However, in actual use, the flour sampling device still has the problem that it cannot sample the flour at a deeper position in the storage bin, resulting in limited use range of the flour sampling device and the obtained flour sample cannot truly reflect the overall condition of the flour in the bin. Therefore, it is necessary to design a sampling device for flour detection that can sample the flour at different depths in the flour storage warehouse. Content of the Utility Model

[0003] In view of the above technical problems, the utility model provides a sampling device for flour detection.

[0004] To solve the above technical problems, the technical solution of the utility model is: a sampling device for flour detection, including a sampling tube, a conical head, and a rotating rod. A limiting plate and a positioning plate are fixedly connected inside the sampling tube. The rotating rod is located inside the sampling tube and is slidably connected to the limiting plate and the positioning plate. A movable plate is slidably connected inside the sampling tube. One side of the movable plate is fixedly connected to the lower end of the rotating rod, and the other side is fixedly connected to a sampling box. The other end of the sampling box is fixedly connected to the bottom of the conical head. The upper end of the sampling tube is threadedly connected to an extension tube. The upper end of the rotating rod is detachably connected to an extension rod, and the upper end of the extension rod is detachably connected to a rotating grip.

[0005] Further, a limiting ring is fixedly connected between the limiting plate and the positioning plate on the rotating rod.

[0006] Further, a sampling grip is threadedly connected to the upper end of the extension tube.

[0007] Further, the upper end of the rotating rod is detachably connected to the extension rod through a ball mechanism. The ball mechanism includes a ball, a pedestal, and a ball spring. The ball is fixedly connected to the upper end of the pedestal. Two pedestals are symmetrically arranged up and down. The two ends of the ball spring are respectively fixedly connected to the lower ends of the two pedestals. A ball hole is opened on the rotating rod, and a positioning hole is opened on the extension rod. The ball passes through the ball hole and is clamped with the positioning hole. The upper end of the extension rod is also detachably connected to the rotating grip through the ball mechanism.

[0008] Furthermore, at least one set of the extension tube and the extension rod is installed. Both ends of the extension tube can be detachably connected by threads, and both ends of the extension rod can be detachably connected by the ball mechanism.

[0009] The utility model has the following advantages compared with the prior art:

[0010] By detachably connecting the extension tube and the extension rod to the sampling tube and the rotating rod, the utility model can achieve the sampling extension distance of the device by connecting multiple extension tubes and extension rods, improving the application range of the device. The operator can connect multiple extension tubes and extension rods according to the actual sampling depth to sample the flour at a deeper position, avoiding the situation that the flour sample cannot truly reflect the overall condition of the flour in the bin due to the inability to sample the flour at a deeper position.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following will further illustrate the utility model with reference to the drawings.

[0016] As Figures 1 to 3 shown, a sampling device for flour detection includes a sampling tube 1, a conical head 2, and a rotating rod 3. A limiting plate 4 and a positioning plate 5 are fixedly connected inside the sampling tube 1. The rotating rod 3 is located inside the sampling tube 1 and is slidably connected to the limiting plate 4 and the positioning plate 5. A movable plate 6 is slidably connected inside the sampling tube 1. One side of the movable plate 6 is fixedly connected to the lower end of the rotating rod 3, and the other side is fixedly connected to a sampling box 7. The other end of the sampling box 7 is fixedly connected to the bottom of the conical head 2. The diameter of the bottom circle of the conical head 2 is larger than the inner diameter of the lower port of the sampling tube 1. When the conical head 2 is not pushed out, the bottom of the conical head 2 abuts against the lower port of the sampling tube 1. The upper end of the sampling tube 1 is threadedly connected to an extension tube 8, the upper end of the rotating rod 3 is detachably connected to an extension rod 9, and the upper end of the extension rod 9 is detachably connected to a rotating grip 10.

[0017] In order to limit the length of the forward and backward displacement of the rotating rod 3 in the sampling tube 1 and prevent the rotating rod 3 from falling out of the positioning plate 5, a limiting ring 11 is fixedly connected between the limiting plate 4 and the positioning plate 5 on the rotating rod 3.

[0018] In order to facilitate the operator to use the device, the upper end of the extension tube 8 is detachably connected with a sampling grip 12 through threads. With the help of the sampling grip 12, the operator can insert the device into the flour to be sampled more labor - savingly.

[0019] In order to achieve the detachable connection between the rotating rod 3 and the extension rod 9, the upper end of the rotating rod 3 is detachably connected with the extension rod 9 through a ball mechanism. The ball mechanism includes a ball 13, a pedestal 14, and a ball spring 15. The ball 13 is fixedly connected to the upper end of the pedestal 14. There are two pedestals 14 arranged symmetrically up and down. The two ends of the ball spring 15 are respectively fixedly connected to the lower ends of the two pedestals 14. A ball hole is opened on the rotating rod 3, and a positioning hole 16 is opened on the extension rod 9. The ball 13 passes through the ball hole and is clamped with the positioning hole 16. The upper end of the extension rod 9 is also detachably connected with the rotating grip 10 through a ball mechanism.

[0020] In order to extend the sampling depth of the device, at least one set of the extension tube 8 and the extension rod 9 is installed. When two or more extension tubes 8 and extension rods 9 are installed on the device, the adjacent ends of the two extension tubes 8 are detachably connected through threads, and the adjacent ends of the two extension rods 9 are detachably connected through a ball mechanism.

[0021] The specific working process of the utility model is as follows:

[0022] The operator screws the sampling grip 12 onto the extension tube 8 through threads, pulls the extension rod 9 upward so that the bottom of the conical head 2 abuts against the lower end of the sampling tube 1, preventing flour from entering the sampling box 7 when the device penetrates into the flour. Observe the scales on the sampling tube 1 and the extension tube 8. After reaching the sampling position depth, push the rotating grip 10 downward until the limiting ring 11 touches the limiting plate 4. At this time, the sampling box 7 extends out of the sampling tube 1. Rotate the rotating grip 10 to drive the extension rod 9 and the rotating rod 3 to rotate, thereby driving the movable plate 6 and the sampling box 7 to rotate, and sampling the flour at this position. After rotating the rotating grip 10 one circle, pull the rotating grip 10 upward to retract the sampling box 7 into the sampling tube 1, pull out the device, pour the taken flour sample into a sample bag, clean the sampling box 7 with a brush, and then sample the flour at another position. If the sampling position depth at this time is relatively deep, the rotating grip 10 and the sampling grip 12 can be removed first, and then the extension tube 8 and the extension rod 9 are connected again to the extension tube 8 and the extension rod 9 respectively until the sampling depth requirement is met, and then the rotating grip 10 and the sampling grip 12 are respectively installed at the outermost ends of the extension rod 9 and the extension tube 8, and sample the flour again according to the same steps.
