Description

Technical Field

[0001] The invention relates to the field of rice appearance detection, and more specifically, to a rapid rice quality detection device. Background Art

[0002] The rice appearance quality detector is a device specially used to evaluate the appearance characteristics and quality of rice. It uses advanced optical and image processing technology to quickly and accurately analyze and evaluate the shape, color, size, integrity, etc. of rice. It has the functions of shape and size analysis, color evaluation, integrity detection, and automatic operation;

[0003] The specific operation steps are as follows: place the detector on the detection table and connect it to the computer, open the flap, place the rice in the instrument detection area, close the flap, start the detection program on the computer, and automatically inspect the rice quality through the computer program.

[0004] Since the positions of the grains in the above method cannot be unified, the prior art will use a fixed-distance grain tray to evenly spread the grains first, and then place the grain tray in the detection area of ​​the detector for detection. The grain spreading step is to tilt the grain tray and pour the rice into the grain tray from above, and scatter the grains in the grain tray by manual shaking. However, in actual use, it is found that this method has high requirements on the stability and amplitude of the shaking of the detection personnel. It is difficult to scatter with a small force, and it is easy to cause the grains to fall with a large force. Secondly, the position of the existing manually placed grain tray is inaccurate, and the coordinate position of the unqualified product cannot be accurately marked by the cooperation of the computer program and the detector, which increases the workload of the subsequent deep detection of the residual product picking work;

[0005] In order to solve the above problems, this application proposes a rapid rice quality detection equipment. Summary of the invention

[0006] The purpose of the present invention is to provide a rice quality rapid detection device, which can achieve the purpose of stably spreading the grains on the rice tray by arranging a support frame matched with a detector for positioning the rice tray.

[0007] The object of the present invention can be achieved by the following technical scheme: a rice quality rapid detection equipment, the detection equipment body includes a detection seat placed on a detection table and a flip cover hinged on the detection seat, the detection seat is formed with a detection area matched with the flip cover, and also includes a rice plate for loading rice grains, and also includes:

[0008] A bracket is hinged on the upper end of the detection seat and formed on the periphery of the detection area. The hinge of the bracket can make the grain plate tilt on the detection seat to spread the grains. The bracket provides a carrier for disassembly and assembly of the grain plate and movement, making the detection work more accurate and efficient.

[0009] A top plate is elastically mounted on the bracket and can position the grain tray in the bracket, wherein the elastic movable space of the top plate is used for inserting the grain tray and determining the front and rear position of the grain tray on the bracket;

[0010] A positioning plate is arranged in the horizontal direction and provided to enable the grain tray to slide back and forth at a fixed distance on the bracket. The positioning plate is arranged on the top plate and a positioning spring is provided at the connection point to place the grain tray at a certain position under normal conditions. Through the front and rear positioning of the top plate and the bracket and the left and right positioning of the positioning spring, the computer connected to the detection equipment can accurately mark the coordinates of the residual products on the grain tray, which is convenient for the subsequent processing of the residual grains.

[0011] The bracket includes a rectangular sleeve at one end and a C-shaped plate at the other end, the side of the rectangular sleeve is provided with a hinge shaft hinged to the detection seat, and the C-shaped plate is close to the operating side of the personnel;

[0012] The top plate is installed from the rear end of the rectangular sleeve and is restricted to move in the rectangular sleeve under the cooperation of the sealing plate and the third screw. An engaging groove is arranged on the inner side of the top plate. A spring piece is abutted between the engaging groove and the sealing plate to clamp the valley plate between the top plate and the C-shaped plate.

[0013] In the above technical solution, through the cooperation of the sealing plate and the third screw, the top plate can be effectively restricted from moving in the rectangular sleeve, and the elasticity of the spring sheet provides space for the valley plate to be inserted into the rectangular sleeve and the C-shaped plate. When the valley plate is inserted, the spring sheet is in a reset state, preventing the spring sheet from pressing the valley plate between the positioning plate and the C-shaped plate and making it unable to move left and right.

[0014] Symmetrical slide grooves are provided on both sides of the top plate, and a slider is slidably provided in the slide grooves. The slider is fixed to the positioning plate by a second screw and slides back and forth along the slide grooves in the top plate at the same time. The left and right sides of the top plate are openings that enable the positioning plate to slide left and right.

[0015] In the above technical solution, the positioning plate is installed on the top plate and defines a movable path, so that the grains can be more evenly spread in the grain tray in an inclined state.

[0016] A support plate is also formed on the inner side of the top plate, a guide rod is inserted in the support plate, the guide rod passes through the slider and is fixed in the top plate by a first screw, the detection area positioning spring is sleeved on the outside of the guide rod and one end is fixed on the inner side of the slide groove, and the other end is in contact with the slider;

[0017] In the above technical solution, the guide rod can provide positioning spring support while improving the movement stability of the slider, and the cooperation with the support plate and the first screw facilitates assembly and replacement of parts when they are damaged in the future.

[0018] The end of the guide rod inserted into the support plate is provided with a positioning head, and the other end is provided with a thread groove matched with the first screw, and the slider is penetrated with a guide hole slidably matched with the guide rod;

[0019] In the above technical solution, the guide rod can be conveniently assembled and disassembled in the top plate through the cooperation between the positioning head and the threaded groove and the first screw.

[0020] Positioning blocks for positioning the grain tray left and right are vertically arranged at both ends of the positioning plate, and a guide plate is formed at the front end of the positioning block to facilitate the insertion of the grain tray;

[0021] In the above technical solution, the positioning block ensures the left and right position of the grain tray on the positioning plate, so that the positioning plate can drive the grain tray to move synchronously when it moves left and right, and the guide plate can enable the grain tray to be inserted quickly and conveniently, thereby improving the operating efficiency.

[0022] The bottom depths of the rectangular sleeve and the C-shaped plate close to the valley plate are greater than the top depths;

[0023] In the above technical solution, the bottom depth is greater than the top depth, which can not only facilitate the insertion of the valley plate, but also improve the stability of the valley plate after insertion.

[0024] The C-shaped plate is integrally formed with a strip on the side away from the grain plate for manually rotating the grain plate and the bracket upward;

[0025] In the above technical solution, the pull bar enables the operator to easily lift the grain tray and one side of the bracket upward along the hinged path and place them in an inclined state to facilitate the spreading of the grains.

[0026] The valley plate includes a dispersion area that can be placed inside the C-shaped plate and a residual material trough that can be placed in a rectangular sleeve and is in close contact with the positioning plate, and the dispersion area is provided with evenly distributed valley troughs;

[0027] In the above technical solution, the dispersing area and the grain trough evenly disperse the grains, and the residual material trough collects the grains that enter the grain trough to prevent the grains from piling up and falling.

[0028] Beneficial effects of the present invention:

[0029] The present invention directly sets the grain tray on the detector, and can mark the coordinates of the residual grains at fixed positions through the grain grooves evenly distributed on the grain tray and the computer program. After the grains are detected, the grain tray is taken out, and the position of the residual grains in the grain tray can be accurately determined and picked out through the coordinate information on the computer program, which provides convenience for the subsequent in-depth detection of the residual grains.

[0030] The present invention allows the grain tray to be easily disassembled on the detector and also provides a fixed reciprocating motion path. After the grains are poured onto the grain tray, they reciprocate along the fixed path. This allows the direction of force to be consistent and the strength to be better controlled, so that the grains can be more evenly scattered on the grain tray, ensuring the grain content in the grain tray and further improving the detection efficiency.
