The screening holes on the upper screening screen are larger than the screening holes on the lower screening screen.

[0011] Both of the mounting components include mounting frames, the left ends of both mounting frames are fixedly connected to concave plates, the left and right ends of both mounting frames are fixedly connected to the relatively close ends of eight sliding support rods, and the inner rear sides of both mounting frames overlap with the rear ends of two screening frames.

[0012] Two crossbars are fixedly connected to the rear side of each of the two mounting frames. The four crossbars are respectively inserted into four mounting blocks, each with a limit hole in its interior. The two mounting frames are slidably connected to eight insert rods through four through holes in their upper interior.

[0013] The eight insertion rods are divided into four groups, and their lower ends are respectively inserted into four mounting blocks, each with two insertion holes inside.

[0029] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0030] like Figure 1-7 As shown, a layered sieving tool for soil pest detection includes a base plate 1. A motor 3 is fixedly installed on the upper end of the base plate 1. The output shaft of the motor 3 is fixedly connected to a rotating rod 6. A circular turntable 8 is fixedly connected to the upper end of the rotating rod 6. The circular turntable 8 is movably connected to a T-shaped push-pull plate 9 with a push-pull groove inside through a push-pull rod set at its upper end. A concave plate 10 is fixedly connected to the right end of the T-shaped push-pull plate 9. The right end of the concave plate 10 is fixedly connected to two mounting components 7. The two mounting components 7 are respectively inserted into four mounting blocks 13, each with a limit hole and two insertion holes inside. The four mounting blocks 13 are respectively connected to two sieving frames 15. The left and right ends are fixedly connected, and the bottom ends of the two screening frames 15 are each equipped with a screening screen 16. The rotation of the output shaft of the motor 3, under the action of the rotating rod 6, can drive the circular turntable 8 to rotate. The rotation of the circular turntable 8, in conjunction with the push-pull rod, T-shaped push-pull plate 9 and concave plate 10, can drive the two mounting components 7 to sway left and right. Then, with the cooperation of the four mounting blocks 13, the two screening frames 15 can be driven to sway left and right. At this time, under the action of the screening screen 16 at the bottom ends of the two screening frames 15, the soil can be stratified and screened.

[0031] The rear ends of the two screening frames 15 are respectively connected to the two mounting components 7. The rear ends of the two mounting components 7 are movably connected to the drive connection component 17. The upper end of the drive connection component 17 is fixedly connected to the fixed frame 2. Two sliding support rods 5 are fixedly connected to the left and right ends of the two mounting components 7. The eight sliding support rods 5 are slidably connected to the fixed frame 2, which has four sliding through holes in the left and right ends. Through the cooperation of the mounting components 7, the mounting block 13 and the drive connection component 17, the installation process of the screening frame 15 can be quickly realized. Correspondingly, after screening, the screening frame 15 can be removed from the device to facilitate the cleaning of soil and other impurities that have not passed the screening. At the same time, it is also convenient to replace the screening frame 15 and the screening screen 16. The cooperation between the sliding support rods 5 and the fixed frame 2 can limit the movement direction of the mounting components 7.

[0032] Furthermore, the lower end of the fixed frame 2 is fixedly connected to the upper end of the base plate 1, and the upper end of the fixed frame 2 is fixedly connected to the hopper 11. The left and right sides inside the fixed frame 2 are respectively fixedly connected to the left and right ends of the guide frame 14. The lower side of the guide frame 14 is correspondingly provided with a collection box 12, which overlaps the upper end of the base plate 1. The upper side of the rotating rod 6 is movably connected to the upper end of the L-shaped plate 4, and the lower end of the L-shaped plate 4 is fixedly connected to the upper end of the base plate 1. The screening holes on the upper screening screen 16 are larger than those on the lower screening screen 16. The guide frame 14 can conveniently guide the qualified soil after screening to the inside of the collection box 12 for collection. The L-shaped plate 4 can support the rotating rod 6.

[0033] Furthermore, both mounting components 7 include mounting frames 71. The left ends of both mounting frames 71 are fixedly connected to the concave plate 10. The left and right ends of both mounting frames 71 are fixedly connected to the relatively close ends of eight sliding support rods 5. The rear inner sides of both mounting frames 71 overlap with the rear ends of two screening frames 15. Two crossbars 72 are fixedly connected to the rear inner sides of both mounting frames 71. The four crossbars 72 are respectively inserted into four mounting blocks 13, each with a limit hole inside. Both mounting frames 71 are slidably connected to eight insert rods 75 through four through holes in their upper inner ends. The eight insert rods 75 are divided into four groups, and their lower ends are respectively inserted into four mounting blocks 13, each with two insertion holes inside. The upper ends of the eight insert rods 75 are divided into four groups, and their upper ends are respectively fixedly connected to four connecting plates 73. Each of the four connecting plates 73 is slidably connected to the drive connection assembly 17 through two circular through holes opened inside its rear end. Each of the four connecting plates 73 is movably connected to eight limiting rods 74 through two limiting holes opened inside its interior. The eight limiting rods 74 are divided into two groups, and their lower ends are fixedly connected to the upper ends of the two mounting frames 71 respectively. Through the cooperation between the set crossbars 72, insert rods 75 and mounting blocks 13, the installation process of the screening frame 15 can be quickly realized. By driving the connecting plate 73 to move upward, the corresponding two insert rods 75 can be driven to move upward, so that the insert rods 75 are moved out of the insertion holes opened inside the corresponding mounting blocks 13. At this time, the screening frame 15 can be easily removed from the device by pulling it forward. The set limiting rods 74 can limit the movement direction of the connecting plate 73.

[0034] The drive connection assembly 17 includes four support rods 175. Each of the four support rods 175 is slidably connected to a connecting plate 73, each with two circular through holes at its rear end. The four support rods 175 are fixedly connected to the upper and lower ends of a fixed base 174. An electric telescopic rod 172 is fixedly connected to the upper end of the fixed base 174. The upper end of the electric telescopic rod 172 is fixedly installed inside the upper side of the connecting frame 171. The connecting frame 171 is fixedly connected to the rear end of the fixed frame 2. The fixed base 174 is slidably connected to two fixed rods 173 through two limiting holes inside it. The upper and lower ends of the two fixed rods 173 are fixedly connected to the upper and lower sides inside the connecting frame 171, respectively. By activating the electric telescopic rod 172, the fixed base 174 is moved upward, which in turn moves the four support rods 175 upward, thereby moving the corresponding connecting plate 73 upward. The limiting rods 74 restrict the movement direction of the fixed base 174.

[0035] The working principle of this utility model is as follows:

[0036] When using this device to perform stratified soil screening, the motor 3 drives the rotating rod 6 to rotate, which, in conjunction with the circular turntable 8, T-shaped push-pull plate 9, concave plate 10, mounting assembly 7, and mounting block 13, causes the two screening frames 15 to sway left and right. Soil is then placed into the hopper 11, gradually falling into the upper screening frame 15. After being screened by the screening mesh 16 at the bottom of the upper screening frame 15, the soil falls into the lower screening frame 15, and after being screened by the screening mesh 16 at the bottom of the lower screening frame 15, it falls through the guide frame 14 into the collection box 12. To achieve the effect of stratified sieving of soil, after sieving, the electric telescopic rod 172 is activated to move the fixed base 174 upward. Then, under the action of the four support rods 175, the four connecting plates 73 can be moved upward. By moving the four connecting plates 73 upward, the eight insert rods 75 can be moved out from the two insertion holes opened inside the four mounting blocks 13. At this time, the two screening frames 15 can be easily removed from the device by pulling them forward. This allows for the cleaning of soil and other impurities that have not passed the screening inside the two screening frames 15. At the same time, the screening frames 15 and the screening screen 16 can be easily replaced as needed.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
