[0031] Next, the technical solution for the pretreatment device used for agricultural product detection in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0032] Embodiment 1

[0033] Referring to the drawingsFigures 1 - 3 As shown, a pretreatment device for agricultural product detection includes:

[0034] A crushing box 10 set in a trapezoidal structure;

[0035] A crushing assembly 20, which includes a driving assembly arranged outside the crushing box 10 and two crushing rollers 27 with opposite rotation directions inside the crushing box 10. The driving assembly includes a driver and a linkage assembly. When the driver works, the two crushing rollers 27 are driven to rotate in opposite directions through the linkage assembly;

[0036] An extrusion assembly 30, which includes two clamping plates 35 slidably arranged inside the crushing box 10 and a cooperation assembly outside the crushing box 10. The opposite rotation of the two crushing rollers 27 drives the two clamping plates 35 to move away from or towards each other through the cooperation assembly to achieve continuous extrusion.

[0037] By controlling the operation of the driver, with the cooperation of the linkage assembly, the two crushing rollers 27 are driven to rotate relatively to crush the agricultural products placed inside the crushing box 10. At the same time, the opposite rotation of the crushing rollers 27, with the cooperation of the cooperation assembly, drives the two clamping plates 35 to move reciprocally away from or towards each other, so as to continuously extrude the crushed agricultural products. By integrating the functions of crushing and extrusion into the same device, the cumbersome process that requires multiple devices to assist in the traditional method is avoided. The operator only needs to operate one device to complete the whole process of crushing and squeezing out the juice from the agricultural products, reducing the operation steps and manual intervention, lowering the operation complexity, greatly saving the time required for intermediate links such as equipment conversion and material transfer, and thus significantly improving the work efficiency.

[0038] The cooperation assembly includes a through groove 33 penetratingly opened inside the crushing box 10. Limiting columns 34 are fixedly connected inside the through groove 33. The clamping plates 35 are slidably connected to the outer periphery of the limiting columns 34 and their ends extend to the outside of the through groove 33. The clamping plates 35 are set in a concave structure that cooperates with the trapezoidal crushing box 10, so that the working area of extrusion is located below the through groove 33, avoiding the outflow of agricultural product raw materials or extruded juice from the through groove 33 during the extrusion process.

[0039] The collaborative component further includes a driven plate 36 fixedly connected to the outer side of the clamping plate 35. A driven groove 37 is formed through the inside of the driven plate 36. The outer sides of the crushing rollers 27 are fixedly connected with rotating shafts 24 that penetrate through the crushing box 10. The ends of the rotating shafts 24 penetrate through the crushing box 10 and are fixedly connected with connecting plates 31. Linkage shafts 32 are fixedly connected inside the connecting plates 31. The linkage shafts 32 penetrate through the driven grooves 37. Under the rotational cooperation of the rotating shafts 24, the connecting plates 31 can be driven to rotate, thereby driving the linkage shafts 32 to revolve around the rotating shafts 24. Through the interaction force between the linkage shafts 32 and the driven grooves 37, and with the limiting effect of the limiting posts 33 on the clamping plate 34, a reciprocating squeezing action is achieved.

[0040] The linkage component includes a motor bracket 21 fixedly connected to one side of the crushing box 10. The driver is set as a servo motor 22. The servo motor 22 is fixedly installed on the top of the motor bracket 21. The outer periphery of the output end of the servo motor 22 is fixedly connected with a driving wheel 23. The outer periphery of the end of one of the rotating shafts 24 is fixedly connected with a driven wheel 25 connected to the driving wheel 23 through a belt. By controlling the operation of the servo motor 22, the driving wheel 23 is driven to rotate. Under the transmission cooperation of the belt, the driven wheel 25 is driven to rotate, thereby providing the driving force for the rotation of the rotating shaft 24.

[0041] The linkage component further includes a first gear 26 and a second gear 28 arranged on the side of the crushing box 10 away from the servo motor 22. The first gear 26 and the second gear 28 are respectively fixedly connected to the outer peripheries of the two rotating shafts 24 and are meshed with each other. The diameters and the number of teeth of the first gear 26 and the second gear 28 are equal. Through the rotation of the rotating shaft 24, the first gear 26 is driven to rotate. Under the meshing cooperation, the second gear 28 is driven to rotate in the opposite direction and at the same speed as the first gear 26.

[0042] The closest distance between two adjacent driven plates 36 is greater than the width of the motor bracket 21, ensuring that the driven plate 36 will not interfere with the motor bracket 21 during the rotation for squeezing operation. A filter plate 40 is slidably arranged inside the crushing box 10 and below the clamping plate 35. The arrangement of the filter plate 40 can effectively separate the squeezed agricultural product particles from the juice, ensuring that the extracted juice has a high purity. After the squeezing is completed, the filter plate 40 is slid out, so that the squeezed agricultural products fall naturally.

[0043] A limiting hopper 11 is fixedly connected to the top of the crushing box 10. The height of the limiting hopper 11 is greater than the diameter of the crushing roller 27. A guiding member 12 is fixedly connected to the bottom of the crushing box 10. The bottom of the guiding member 12 is threadedly connected to a collection box 13. The design of the limiting hopper 11 helps to guide agricultural products to accurately fall into the interior of the crushing box 10, reducing material scattering and waste. At the same time, the limiting hopper 11 also plays a certain safety protection role, preventing the hands of operators or other objects from accidentally entering the crushing area and ensuring operation safety. The collection box 13 is used to collect the juice generated after extrusion. After detecting the juice, the collection box 13 is also used to collect the agricultural products after extrusion.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and the inventive concept of the present invention for the pretreatment device for agricultural product detection, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
