Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing instruments, and in particular to a control mechanism for material falling in a grain measuring instrument. Background Technology
[0002] Currently, it is necessary to regularly measure the grain in the warehouse. The measurement items include the degree of mold per unit weight. The current method is to take samples of the grain back to the laboratory for quantitative testing. The testing equipment includes a tray containing the grain and a camera facing the tray. The camera captures whether there is mold per unit area and the area of mold. The data is then processed to determine the degree of mold.
[0003] The currently found Chinese patent, CN117589676A, entitled "A Rice Mold Degree Detection Device and Operating Method," describes a rice mold degree detection device comprising a support frame with a movably connected camera externally. An adjustment component includes a support plate, with an adjustment motor externally mounted on the support plate. The adjustment motor is fixedly connected to the support plate via a bracket. A rotatably connected support frame is mounted on the outside of the support plate via a shaft. This invention provides a rice mold degree detection device that allows the rice grains held inside to be flipped during detection by adjusting the component. This facilitates comprehensive identification of both sides of the rice grains by the camera, avoiding blind spots and improving the accuracy of subsequent detection.
[0004] For example, the Chinese patent "An Optical Grain Mold Detection Device" (publication number CN222952218U) includes a material bucket, a grinding mechanism, a buffer discharge device, and a fluorescence detection unit. The material bucket has an inlet and an outlet for easy material input and output. The grinding mechanism includes a fixed grinding sleeve and a moving grinding roller, which form a precise grinding gap to ensure uniform and fine grinding of the material. The buffer discharge device includes a discharge chamber, a moving discharge plate, and a pressing plate to effectively regulate the material flow rate. The fluorescence detection unit uses a fluorescent lamp column and a spectral acquisition plate to efficiently detect mold in the material. A rotary motor drives the moving grinding roller to rotate, achieving automated operation. This device is ingeniously designed and fully functional, providing a convenient and efficient solution for mold detection.
[0005] The aforementioned device can detect mold growth in grains, but it cannot control the falling of grains to perform different detection tasks in different chambers. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a control mechanism for material falling in a grain measuring device. The mechanism is reasonably designed and is conducive to controlling the falling of grain.
[0007] The control mechanism for material falling in the grain measuring instrument of this utility model is characterized by: an elastic partition disposed in the cylinder to divide the inner cavity of the cylinder into an upper cavity and a lower cavity; a limiting buckle on the cylinder to restrict the elastic partition from opening; a first end of the elastic partition being rotatably connected to the cylinder; a second end of the elastic partition being provided with a push-back protrusion extending out of the cylinder; a first end of the limiting buckle being connected to the cylinder; a second end of the limiting buckle extending out of the cylinder; a first wedge block on the limiting buckle; and a second wedge block on the elastic partition that cooperates with the first wedge block for limiting the movement.
[0008] Preferably, the first end of the aforementioned limiting buckle has two screw mounting countersunk holes, and the cylinder body is provided with corresponding screw holes. By installing screws in the screw mounting countersunk holes and screw holes, the limiting buckle and the cylinder body are installed and fixed.
[0009] Preferably, the aforementioned limiting buckle is an arc-shaped plate with a staggered structure near the first end to facilitate pressing and bending of the limiting buckle; an intermediate stiffening plate is provided on the bottom surface of the staggered position to increase the rigidity of the staggered position.
[0010] Preferably, one side of the intermediate stiffener is connected to the edge of the countersunk hole for screw installation, and the other side of the intermediate stiffener is connected to the junction of the staggered layer position.
[0011] Preferably, the cross-sections of the first wedge and the second wedge are both triangular.
[0012] Preferably, the first end of the elastic partition is provided with a torsion spring that drives the elastic partition to swing outward of the cylinder.
[0013] Preferably, the above-mentioned cylinder is provided with a through groove parallel to the bottom surface of the cylinder, and the elastic partition is provided in the through groove, with the first end of the elastic partition rotatably connected to the inner side of the through groove.
[0014] Preferably, the above-mentioned cylinder is composed of an upper half and a lower half that are stacked on top of each other, with the upper cavity, elastic partition and through groove provided on the upper half, and the lower cavity provided in the lower half.
[0015] Preferably, the lower surface of the upper half and the upper surface of the lower half are fitted together for positioning, and the outer wall surfaces of the upper half and the lower half are smoothly transitioned to form a continuous surface on the outer surface of the cylinder. Both the upper half and the lower half are provided with ring handles on their sides. The ring handles on the upper half and the lower half are stacked and joined together to form an "8" shape. The outer wall surfaces of the ring handles on the upper half and the lower half are smoothly transitioned to form a continuous surface on the outer surface of the cylinder.
[0016] In use, when the elastic partition separates the upper and lower cavities, the second wedge is limited by the first wedge. When the second end of the limiting buckle is pressed down, the first wedge on the limiting buckle is released from its restriction on the second wedge, and the elastic partition springs open to connect the upper and lower cavities. When the return protrusion pushes the elastic partition back, the second wedge on the elastic partition is again limited by the first wedge. In this state, the elastic partition divides the inner cavity of the cylinder into the upper and lower cavities. In the upper cavity, one item of testing can be performed on the grains located therein. When the second end of the limiting buckle is pressed down, the first wedge on the limiting buckle is released from its restriction on the second wedge, and the elastic partition springs open to connect the upper and lower cavities. At this time, the grains located in the upper cavity fall into the lower cavity, so that another item of testing can be performed on the grains in the lower cavity.
[0017] The grain measuring device of this invention has a reasonable control mechanism for material falling, which is conducive to controlling the falling of grain. Attached Figure Description

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be pointed out that the following detailed description is exemplary and intended to provide further explanation of the present application; unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0029] The grain measuring device includes a cylinder 1, a vertical cavity inside the cylinder, and an elastic partition 2 on the cylinder. The elastic partition 2 divides the vertical cavity into an upper partition 3 and a lower partition 4. The upper partition 3 is equipped with a stirring head 5 that can agitate the grain, and the upper part of the upper partition 3 is equipped with a camera 6 that captures images of the grain.
[0030] The top of the cylinder 1 is provided with a flip-up cover 7. The camera 6 is installed on the bottom surface of the cover and the camera faces downward so as to be directly opposite the stirring head. The first side of the cover 7 is rotatably connected to the side of the opening of the cylinder (that is, the upper opening of the upper cavity 3), and the second side of the cover 7 is fastened to the other side of the opening of the cylinder.
[0031] The agitator 5 is connected to the output shaft of a horizontally placed reducer 8. The output shaft of the reducer 8 is vertically arranged, and the input end of the reducer is connected to the output shaft of the motor 9. The motor 9 is powered by a storage battery 10. The agitator 5 is equipped with several agitator blades to stir the grains. The reducer 8 is a commercially available component that can reduce the rotational speed of the motor output. The agitator 5 is located at the lower part of the upper cavity 3. The grains placed in the upper cavity 3 can submerge the agitator 5. The agitator agitates the grains to turn them over.
[0032] A weighing device 11 is provided at the bottom of the lower compartment, which is used to weigh the grain falling into the lower compartment.
[0033] In use, the grain to be tested is placed in the upper chamber, and a camera is used to detect mold growth (the camera captures an image of the grain surface, and the image is processed to obtain the mold growth status, which is existing technology and will not be elaborated here). Then, the stirring head rotates for several seconds and then stops (stirring allows the grain to be turned over, so that other parts of the grain can be captured). The camera captures an image again to detect mold growth. Then, the elastic partition pops open to connect the upper and lower chambers, and the grain in the upper chamber falls into the lower chamber. The weight of the grain in the cylinder can be measured by a weighing device located at the bottom of the lower chamber. This weighing device is a commercially available component.
[0034] When the mold content per unit weight is lower than the standard value, a sample can be taken at another location for testing. If the mold content per unit weight is higher than the standard value, a sample should be taken again at the original location to confirm the mold content of the grain and to deal with it in a timely manner. (The sampling and testing methods and procedures here can be adjusted according to actual needs; this is just an example.)
[0035] To facilitate use and make reasonable use of the cylinder space, a handle 12 is provided on the side of the cylinder 1, and the battery 10 is located in the housing at the handle 12 position, so that the internal space of the handle can be utilized. The handle shape can be bent, U-shaped, etc. A charging interface for charging the battery 10 is provided on the cylinder (how to charge is existing technology and will not be described in detail here).
[0036] The upper part of the handle 12 is inclined to provide a display screen 13. The display screen 13 is electrically connected to the controller located in the handle body. The controller is electrically connected to the camera and the motor. The controller receives the image data captured by the camera and displays the detection results on the display screen. After capturing an image, the controller controls the motor to work for several seconds to stir the grain (the working principle of the above controller is existing technology and will not be described in detail here).
[0037] To control the elastic partition, a limiting buckle 14 is provided on the cylinder to restrict the elastic partition 2 from opening. The first end of the elastic partition 2 is rotatably connected to the cylinder 1, and the second end of the elastic partition 2 is provided with a return protrusion 20 extending out of the cylinder (for the user to manually return the elastic partition 2 to its initial state, i.e., the elastic partition 2 divides the inner cavity of the cylinder into an upper cavity and a lower cavity). The first end of the limiting buckle 14 is connected to the cylinder, and the second end of the limiting buckle 14 extends out of the cylinder. The limiting buckle 14 is provided with... The first wedge 15 is provided on the elastic partition plate, and the second wedge 16 is provided to cooperate with and limit the first wedge 15. When the elastic partition plate 2 separates the upper cavity 3 and the lower cavity 4, the second wedge 16 is limited by the first wedge 15. When the second end of the limiting buckle is pressed down, the first wedge on the limiting buckle is released from the restriction of the second wedge, and the elastic partition plate springs open to make the upper cavity and the lower cavity communicate. When the return protrusion moves the elastic partition plate back to its original position, the second wedge on the elastic partition plate 2 is again limited by the first wedge.
[0038] Specifically, the first end of the limit buckle 14 has two screw mounting countersunk holes 17, and the cylinder body has corresponding screw holes. By installing screws in the screw mounting countersunk holes and screw holes, the limit buckle and the cylinder body are installed and fixed.
[0039] The limiting buckle is an arc-shaped plate, and its position near the first end has a staggered structure (i.e., the single-layer plate near the first end and the single-layer plate away from the first end are staggered in the thickness direction, such as...). Figure 7As shown), this structural design facilitates the downward bending of the limit buckle; an intermediate stiffener 18 is provided on the bottom surface of the staggered position, which can increase the rigidity of the staggered position and prevent breakage after use; one side of the intermediate stiffener is connected to the edge of the screw mounting countersunk hole, and the other side of the intermediate stiffener is connected to the joint of the staggered position.
[0040] The cross-sections of the first and second wedges are both triangular, preferably isosceles triangles. This structure is beneficial for limiting the elastic partitions of the limiting buckle 14.
[0041] The first end of the elastic partition 2 is provided with a torsion spring 21 that drives the elastic partition to swing outward of the cylinder (the torsion spring 21 is a common commercially available component, which is sleeved on the rotating part, with one end limited on the cylinder and the other end connected to the elastic partition, so that the elastic partition has a tendency to return to the initial state). When the elastic partition 2 separates the upper cavity 3 and the lower cavity 4, the first wedge 15 on the limiting buckle restricts the elastic partition 2 from swinging out of the cylinder.
[0042] In order to realize the movement space of the elastic partition 2, the cylinder 1 is provided with a through groove 19 parallel to the bottom surface of the cylinder. The elastic partition is located in the through groove, the first end of the elastic partition 2 is rotatably connected in the through groove, and the second end of the elastic partition 2 extends out of the through groove.
[0043] For a reasonable design and to facilitate the removal of grains after testing, the cylinder 1 is composed of an upper half 101 and a lower half 102 stacked on top of each other. The upper cavity 3, the elastic partition 2, and the through groove 19 are located on the upper half, and the lower cavity 4 is located in the lower half 102. After the measurement is completed, the upper half 101 and the lower half 102 can be separated, and the grains in the lower cavity of the lower half 102 can be poured out. The operation is convenient and quick.
[0044] The lower surface of the upper body 101 is matched and limited by the upper surface of the lower body 102, that is, by the matching and limiting of the groove 22 (on the upper surface of the lower body 102) and the convex ring 23 (on the bottom surface of the upper body 101). The outer wall surfaces of the upper and lower bodies are smoothly transitioned to form a continuous surface on the outer surface of the cylinder. Both the upper and lower bodies are provided with ring handles on their sides. Figure 1 , 2 As shown), the ring handles on the upper and lower halves are stacked together to form an "8" shape. The outer walls of the ring handles on the upper and lower halves are smoothly transitioned to form a continuous surface on the outer surface of the cylinder.
[0045] Electrical signal metal contacts 27 are provided at the positions corresponding to the groove 22 and the convex ring 23. When the upper half 101 and the lower half 102 are stacked and fastened together, the electrical signal metal contacts of the upper half 101 and the lower half 102 come into contact, thereby realizing the transmission of weighing measurement data.
[0046] The upper part of the ring handle of the upper half 101 has a cavity 24 formed by the outer shell. The cavity 24 is used to place circuit devices such as controllers. The display screen is placed on the upper part of the cavity. The bottom of the cavity 24 is densely covered with heat dissipation holes 25. The arrangement of the heat dissipation holes 25 here is not only conducive to heat dissipation, but also to the aesthetics of the device. The display screen is set on the upper part of the handle, which is not only convenient to operate, but also conducive to a compact structure.
[0047] The lower cavity 4 is located inside the concave cylinder 26, which is detachably connected to the lower half. The concave cylinder 26 is cylindrical and fits into the lower half, with its bottom in contact with the weighing device 11, so as to weigh the grains that fall into the concave cylinder 26.
[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
