[0002] As agricultural production levels improve, the quality requirements for agricultural products are also becoming increasingly demanding. Traditional manual screening methods can no longer meet the needs of modern high-efficiency, low-cost production. Therefore, it is necessary to develop more efficient mechanized screening equipment. Through screening, impurities, stones, insects and other foreign matter can be effectively removed from agricultural products, ensuring product purity and improving quality. Grading agricultural products according to size, shape and weight makes subsequent processing and sales more efficient and meets market demand.
[0003] At present, in the use of the agricultural product detection and screening device in the prior art, since the existing screening device is in the process of screening grains, the grains are generally poured into the interior of the device through the feed port of the device, and the husks and other debris in the grains are blown out by the fan, etc., and the grain feeding process of the existing device is relatively fast when used, which may cause the husks and other debris in the grains to escape from the interior of the device before being blown out, thereby reducing the screening effect of the grains and increasing the workload of the user to a certain extent. Moreover, most of the existing devices only screen the debris inside the grains, which is not convenient for screening grains of different sizes during the screening process, thereby making it inconvenient to check the quality of the grains. Therefore, there is an urgent need for an agricultural product detection and screening device to solve the above problems. Utility Model Content

[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The agricultural product detection and screening device involved in the present invention is not limited to the various structures described in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0023] Example 1
[0024] like Figures 1 to 5 As shown, this embodiment provides an agricultural product detection and screening device, comprising:
[0025] Screening box 1, a feeding structure 2 is provided on the outer surface of the right side of the upper end of the screening box 1, and a bellows 3 is installed on the inner wall of one side of the upper end of the screening box 1, and a honeycomb-shaped air hole is provided on the outer surface of the screening box 1 on one side of the bellows 3, and a debris channel 4 is provided on the inner wall of the other side of the upper end of the screening box 1, a cover plate 5 is hingedly connected to the outer surface of the front end of the screening box 1, and a screening device 6 is provided inside the lower end of the screening box 1, and an impurity box 7 is inserted into the bottom surface of the lower end of the screening box 1, a debris bin 8 is fixedly connected to the outer surface of the left side of the screening box 1, and a box door 9 is hingedly connected to the outer surface of the front end of the debris bin 8, and a storage box 10 is inserted into the lower end of the debris bin 8, and a collecting trough is provided on the outer surface of one side of the upper end of the debris bin 8, and the position of the collecting trough corresponds to the position of the debris channel 4;
[0026] The feeding structure 2 includes a feeding hopper 21, and the outer surface of the lower end of the feeding hopper 21 is fixedly connected to the inner surface of the upper end of the screening box 1. The inner surfaces of the outer surfaces on both sides of the lower end of the feeding hopper 21 are provided with connecting grooves, and the positions of the connecting grooves correspond to the positions of the outer surface of one side of the bellows 3 and the positions of the debris passage 4, respectively. A fan is installed inside the bellows 3, and an air permeable net is provided on the outer surface of the other side of the bellows 3. This design allows the grains to fall into the feeding hopper 21 by starting the fan built into the bellows 3 to blow air into the feeding hopper 21 through the air permeable net, so that the husks and other debris enter the debris passage 4 through the connecting grooves and fall into the storage box 10.
[0027] The feeding structure 2 also includes a feeding plate 22, and the feeding plate 22 is provided with two groups, and the two groups of feeding plates 22 are respectively fixedly connected to the inner wall surfaces on both sides of the upper end of the feeding hopper 21, and a dividing plate 23 is fixedly connected to the inside of the middle position of the feeding hopper 21, and the upper end surface of the dividing plate 23 is located below the middle position of the two groups of feeding plates 22, and the upper end surface of the dividing plate 23 is triangular. When pouring grains into the upper end surface of the feeding hopper 21, the grains can be concentratedly dropped to the middle position through the upper end surfaces of the two groups of feeding plates 22. At this time, the grains can be separated from both sides by the triangular upper end surface of the dividing plate 23, so that the grains can fall more evenly.
[0028] The inner wall surfaces of both ends of the lower end of the feed hopper 21 are fixedly connected with paving plates 24, and there are multiple groups of paving plates 24. The multiple groups of paving plates 24 are all inclined, and the multiple groups of paving plates 24 are staggered with each other, and baffles are provided on the upper end surfaces of the multiple groups of paving plates 24 close to the debris channel 4. This design allows grains to fall on the upper end surfaces of the paving plates 24 and be transported downward through the inclined upper end surfaces of the paving plates 24. The design of multiple groups of paving plates 24 increases the distance that grains fall and are transported. During the falling process of grains, husks and other debris in the grains can be continuously blown out by wind. At this time, the grains can be blocked by baffles during their falling process to prevent the grains from being blown away together.
[0029] Example 2
[0030] like Figure 3~Figure 4 As shown, based on the same concept as the above embodiment, this embodiment further proposes:
[0031] The screening device 6 includes a first card slot 61 and a second card slot 62. The first card slot 61 and the second card slot 62 are both provided with multiple groups corresponding to each other. Multiple groups of first card slots 61 are opened on the inner wall surface of one side of the lower end of the screening box 1, and multiple groups of second card slots 62 are opened on the inner wall surface at the middle position of the lower end of the screening box 1. The screening device 6 also includes a motor 63. A chamber is opened inside the other side of the lower end of the screening box 1, and the chamber is communicated with the multiple groups of second card slots 62, and a motor 63 is installed on the bottom surface of the chamber. A cam 64 is fixedly connected to the outer surface of the output end of the motor 63, and the cam 64 is provided with multiple groups, and the positions of the multiple groups of cams 64 correspond to the positions of the multiple groups of second card slots 62. The inner wall surfaces of the upper and lower ends of the first card slot 61 are engaged with a first mounting plate 65, and the outer surface of one side of the first mounting plate 65 The surface is fixedly connected with a spring 66, and there are multiple groups of springs 66, and one end of each group of springs 66 is fixedly connected to the inner wall surface of one side of the first slot 61. The inner wall surfaces of the upper and lower ends of the second slot 62 are engaged with the second mounting plate 67, and a screen frame 68 is inserted in the middle position of the first mounting plate 65 and the second mounting plate 67. When the motor 63 is started, it can drive the multiple groups of cams 64 to rotate. At this time, the cam 64 can continuously push the second mounting plate 67 outward inside the second slot 62. At the same time, the first mounting plate 65 can be supported by the elasticity of the spring 66, and the outer surface of one side of the second mounting plate 67 can be reset by itself, so that in this process, the screen frame 68 is continuously driven to move left and right by the first mounting plate 65 and the second mounting plate 67, thereby screening the grain inside the screen frame 68;
[0032] There are multiple groups of screen frames 68, and the bottom surfaces of the multiple groups of screen frames 68 are all provided with screen holes, and the apertures of the screen holes are getting smaller from top to bottom. This design can screen grains of different sizes through the design of the screen holes inside the multiple groups of screen frames 68, thereby facilitating the storage and inspection of grains of different sizes.
[0033] Limiting grooves are provided on the inner wall surfaces of the upper and lower ends of the first card slot 61 and the second card slot 62, and limiting plates are provided on the outer surfaces of the upper and lower ends of the first mounting plate 65 and the second mounting plate 67, and the limiting plates provided on the outer surfaces of the upper and lower ends of the first mounting plate 65 and the second mounting plate 67 are respectively engaged and connected to the limiting grooves provided on the inner wall surfaces of the upper and lower ends of the first card slot 61 and the second card slot 62. This design allows the limiting plates to move synchronously with the inside of the limiting grooves during the movement of the first mounting plate 65 and the second mounting plate 67. At this time, the first mounting plate 65 and the second mounting plate 67 can be more stable when moving, and the first mounting plate 65 and the second mounting plate 67 can be prevented from being separated from the inside of the first card slot 61 and the second card slot 62.
[0034] Working principle: When the equipment is in use, the grains to be screened are poured onto the upper surface of the feed hopper 21. At this time, the grains slide down along the upper surfaces of the two groups of feed plates 22, and are evenly divided into two waves by the triangular surface of the upper end of the dividing plate 23. The grains slowly fall through the inclined upper surfaces of the multiple groups of paving plates 24, and during the falling process of the grains, the fan built into the bellows 3 can continuously blow out the husks and other debris in the grains, so that they fall into the debris channel 4, and the husks and other debris eventually fall into the storage box 10 along the debris channel 4, and the grains that have undergone initial screening fall into the screening device 6. By starting the motor 63, the multiple groups of cams 64 are rotated, and the cams 6 4 makes the second mounting plate 67 move laterally inside the second slot 62, and at the same time pushes the first mounting plate 65 to move laterally inside the first slot 61 through the screen frame 68, and the elasticity of the spring 66 makes the first mounting plate 65 and the second mounting plate 67 reset themselves, thereby screening the grains by size through the left and right reciprocating motion of multiple groups of screen frames 68, and finally lift the cover plate 5 to take out the screen frame 68 to check and store the state of the grains, at this time the inside of the screening device 6 can be cleaned, and at the same time the box door 9 can be hinged and rotated to open and take out the storage box 10 from the inside of the debris bin 8, thereby facilitating the cleaning of the inside of the storage box 10. The above is the entire working principle of the present invention.
[0035] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
