[0029] The following will be combined with the attached Figures 1 to 5 This utility model will be described in detail below. The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of them. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of this utility model.

[0030] This utility model provides an improved sample pretreatment device for agricultural product inspection, as Figure 1 - Figure 5 shown, including a slapping component 1. The slapping component 1 includes a housing 101. A clamping cover 102 is hinged to the front side wall of the housing 101. A motor 103 is fixedly connected to the lower side wall of the housing 101. Two slapping blocks 104 are slidably connected to the lower inner side wall of the housing 101. A gear 105 meshing with the slapping blocks 104 is rotatably connected to the lower inner side wall of the housing 101, and the output end of the motor 103 is fixedly connected to the gear 105. Two fixing plates 2 are fixedly connected to the upper inner side wall of the housing 101. An extrusion component 3 is fixedly connected inside the housing 101;

[0031] The extrusion component 3 includes a first shuttle plate 301 slidably connected inside the housing 101. A plurality of uniformly distributed first shuttle grooves 302 are drilled in the first shuttle plate 301. A plug 303 penetrating through the fixing plate 2 is fixedly connected to the side wall of the first shuttle plate 301. A thrust spring 304 is fixedly connected between the fixing plate 2 and the first shuttle plate 301. A shuttle component 6 is slidably connected inside the first shuttle plate 301.

[0032] In this embodiment: When in use, first, the staff cuts the agricultural crops into pieces and puts them into the detection bag, and adds pure water into the detection bag. Then, the detection bag is put into the housing 101, and the clamping cover 102 is covered to clamp the seal of the detection bag. This state is as Figure 1 shown. After that, the staff starts the motor 103. The motor 103 drives the gear 105 to rotate forward and backward. Under the action of meshing with the two slapping blocks 104, the gear 105 drives the two slapping blocks 104 to reciprocate, so that the slapping blocks 104 can slap the left and right sides of the detection bag. During the slapping process, the agricultural crops will be affected by the slapping pressure and continuously shuttle left and right through the first shuttle grooves 302 of the first shuttle plate 301, achieving the mixing effect of the agricultural products and water.

[0033] In the above implementation manner, in order to enable the first shuttle plate 301 to move and squeeze the agricultural crops repeatedly, so as to promote the full mixing of the agricultural crops and water, the following method can be adopted for implementation:

[0034] On the inner wall of the upper side of the outer shell 101, an electromagnet 4 is fixedly connected. Between the two fixing plates 2, an adjusting component 5 is fixedly connected. The adjusting component 5 includes two cross plates 501 fixedly connected between the two fixing plates 2. On both of the two cross plates 501, a disc 502 is rotatably connected. Between the two discs 502, a fixing rod 503 is fixedly connected. On the fixing rod 503, a rotating sleeve 504 is rotatably connected. On the rotating sleeve 504, a connecting rod 505 hinged on the insertion block 303 is fixedly connected. On the lower side wall of the lower disc 502, a square sleeve 506 is fixedly connected. A square rod 507 is inserted into the lower end of the square sleeve 506. Between the square rod 507 and the square sleeve 506, a tension spring 508 is fixedly connected. On the upper side wall of the gear 105, a friction sleeve 509 is fixedly connected. At the lower end of the square rod 507, a conical block 510 matching the friction sleeve 509 is fixedly connected. The upper end of the friction sleeve 509 is arranged in a concave conical shape, and rubber pads are fixedly connected to the inner side wall of the upper end of the friction sleeve 509 and the side wall of the conical block 510.

[0035] In a preferred embodiment, the staff activates the electromagnet 4. The electromagnet 4 generates a repulsive force to push the conical block 510 downward, so that the conical block 510 abuts against the upper end of the friction sleeve 509. Thus, during the forward and reverse rotation of the gear 105, the friction force between the friction sleeve 509 and the conical block 510 drives the disc 502 to rotate forward and backward. The disc 502 continuously pushes and pulls the insertion block 303 through the fixing rod 503 and the connecting rod 505, so that the first shuttle plate 301 reciprocates to squeeze the crops.

[0036] It should be noted that when the electromagnet 4 is not powered on, the first shuttle plate 301 can push against the inner wall of the clamping cover 102 under the push of the thrust spring 304. At this time, the position of the first shuttle plate 301 is also the farthest distance that the fixing rod 503 can rotate to push the insertion block 303.

[0037] The shuttle component 6 includes a second shuttle plate 601 slidably connected inside the first shuttle plate 301. A plurality of uniformly distributed second shuttle grooves 602 are drilled on the second shuttle plate 601. On the second shuttle grooves 602, a cross bar 603 penetrating the first shuttle plate 301 is fixedly connected, and the cross bar 603 penetrates through the two fixing plates 2. Between the two fixing plates 2, a rotating cylinder 604 threadedly connected to the cross bar 603 is rotatably connected. The cross bar 603 inside the rotating cylinder 604 is a columnar body with threads engraved on its surface. Between the two fixing plates 2, a magnetic plate 605 magnetically connected to the electromagnet 4 is slidably connected. On the lower side wall of the magnetic plate 605, a rack 606 meshing with the rotating cylinder 604 is fixedly connected. The surface of the rotating cylinder 604 is fixedly connected with uniformly distributed tooth surfaces.

[0038] In this embodiment, when the electromagnet 4 is activated, the electromagnet 4 also pushes the magnetic plate 605 downward, causing the magnetic plate 605 to drive the rack 606 downward. The rack 606 drives the rotating cylinder 604 to rotate. Further, under the action of the thread, the rotating cylinder 604 drives the second shuttle plate 601 to abut against the detection bag through the cross bar 603. Since the second shuttle groove 602 in the second shuttle plate 601 is smaller than the first shuttle groove 302, the mixing effect of the crops and water can be further improved under the combined pressure of slapping and intermittent extrusion, thereby improving the detection accuracy. It should be noted that since the first shuttle plate 301 abuts against the inner wall of the clamping cover 102 in the initial state and the internal space of the second shuttle plate 601 can accommodate the second shuttle plate 601 at this time, the movement of the first shuttle plate 301 will not affect the second shuttle plate 601. When it is necessary to reset the magnetic plate 605 and the first shuttle plate 301, the staff only needs to change the current of the electromagnet 4 to make the electromagnet 4 generate a suction force on the magnetic plate 605, driving the magnetic plate 605 upward. Subsequently, due to the friction force of its own thread, the rotating cylinder 604 plays a supporting role for the magnetic plate 605 through the rack 606.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
