[0044] Embodiment 1:

[0045] Please refer to Figure 1-Figure 6A foreign soil spraying device comprises a box body 1, a screening plate 2, a vibration mechanism 3, a crushing roller 4, a first driving mechanism 5, a second driving mechanism 6 and a second driving mechanism 6; the foreign soil spraying device also comprises a mixing tank, an agitator, a spraying pump and a nozzle and other structures. It should be noted that the mixing tank, the agitator, the spraying pump and the nozzle and other structures are all prior arts and are not improvements of this embodiment. Their structures are not described in detail here.

[0046] like Figure 2 and Figure 5 As shown, the screening plate 2 is arranged in the box body 1 and is provided with a plurality of small through holes 2b. Soil particles that meet the diameter requirements can fall downward through the through holes 2b, while soil particles that do not meet the diameter requirements remain on the screening plate 2; the vibration mechanism 3 includes a first connecting rod 34, a plurality of second connecting rods 35, a rotating shaft 31, a cam 32 and a first motor 33; the rotating shaft 31 is rotatably arranged in the box body 1 along the width direction of the box body 1, and both ends are also respectively connected to the cam 32, the first motor 33 is arranged on the outer wall of the box body 1, and its output shaft passes through the box body 1 and is connected to the rotating shaft 31; the second connecting rod 35 has a through slot 35a, and the two ends of the plurality of second connecting rods 35 are respectively hinged to the inner wall of the box body 1 and the screening plate 2, one end of the first connecting rod 34 passes through the through slot 35a and is hinged to the screening plate 2, and the other end is hinged to one end of the cam 32.

[0047] The first motor 33 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the cam 32 to rotate, so that the first connecting rod 34 generates a swing amplitude. Under the action of friction force, the first connecting rod 34 drives the plurality of second connecting rods 35 to swing back and forth, driving the screening plate 2 to vibrate.

[0048] It should be noted that the width of the through slot 35a is equal to the width of the first connecting rod 34, so that when the first connecting rod 34 swings, it can use friction to drive the second connecting rod 35 to swing, thereby achieving the purpose of driving the screening plate 2 to vibrate.

[0049] like Figure 1 and Figure 2 As shown, the box body 1 has a feed port 1a, and the feed port 1a is connected to a discharge pipe 11 through a telescopic bellows 12. The discharge pipe 11 is arranged in the box body 1 and can slide along the length direction of the box body 1; when soil enters the box body 1 from the feed port 1a, it is discharged on the screening plate 2 through the discharge pipe 11. Since the discharge pipe 11 is movable, the soil can be evenly spread on the screening plate 2 instead of gathering in a fixed position, which is convenient for the screening plate 2 to better screen the soil.

[0050] like Figure 2As shown, the rodless cylinder 8 is arranged on the inner wall of the box body 1, and its piston end is connected to the discharge pipe 11. Through the movement of the piston end, the discharge pipe 11 is driven to move along the length direction of the box body 1, thereby driving the discharge pipe 11 to move, so that the soil is better spread on the screening plate 2.

[0051] like Figure 2-Figure 4 As shown, the first driving mechanism 5 includes two third connecting rods 51, two sliding blocks 52, a first driving part and a second driving part; the first driving part includes a screw rod 53, a second motor 54 and a fourth connecting rod 55, and the second driving part includes a plurality of telescopic rods 56;

[0052] The side wall of the screening plate 2 has a slide groove 2a, and one end of the slide groove 2a also penetrates the screening plate 2 along the length direction. With such an arrangement, when the screening plate 2 is vibrating, the first driving mechanism 5 allows the crushing roller 4 to be separated from the slide groove 2a, without causing motion interference with the vibration of the screening plate 2, and without causing damage to the structure of the first driving mechanism 5 due to the vibration of the screening plate 2.

[0053] The facing surfaces of the two third connecting rods 51 respectively have protrusions 511, one end of the protrusion 511 passes through the slide groove 2a and can slide along the length direction of the slide groove 2a; the facing surfaces of the two protrusions 511 are respectively provided with sliding blocks 52, and the two ends of the crushing roller 4 are respectively rotatably connected with connecting plates 41, and the connecting plate 41 is slidably connected to the sliding block 52 along the height direction. By sliding the sliding plate, the distance between the crushing roller 4 and the screening plate 2 is changed, so as to better control the crushing roller 4 to crush the soil particles on the screening plate 2.

[0054] Both ends of the fourth connecting rod 55 are respectively connected to the bottom of the two third connecting rods 51 and have threaded holes. The screw rod 53 is rotatably arranged in the box body 1 along the length direction of the box body 1, and one end also passes through the threaded hole. The second motor 54 is arranged on the outer wall of the box body 1, and its output shaft passes through the box body 1 and is connected to the screw rod 53. The screw rod 53 is driven to rotate by the second motor 54, and the fourth connecting rod 55 is driven to drive the two third connecting rods 51 to move, thereby moving the crushing roller 4.

[0055] One end of the telescopic rods 56 is connected to the third connecting rod 51, and the other end is connected to the sliding block 52. The sliding block 52 drives the connecting plate 41 and the crushing roller 4 to move up and down through the extension and contraction of the telescopic rods 56.

[0056] The second driving mechanism 6 includes a third motor 61, a gear 62 and a ring gear 63. The ring gear 63 is sleeved on the crushing roller 4. The third motor 61 is slidably connected to the inner wall of the screening plate 2, and one end is also connected to the connecting plate 41. Such an arrangement allows the third motor 61 to move up and down synchronously with the connecting plate 41; the output shaft of the third motor 61 is connected to the gear 62, and the gear 62 is meshed with the ring gear 63; the gear 62 is driven to move by the second motor 54, so that the ring gear 63 drives the crushing roller 4 to rotate, thereby crushing and crushing the soil particles on the screening plate 2.

[0057] In this embodiment, the first driving unit also includes two guide rods, and the fourth connecting rod 55 is also provided with two guide holes, the two guide holes are located on both sides of the threaded hole, and the two guide rods are arranged in the box body 1 along the length direction of the box body 1, and one end also passes through the guide holes respectively; the guide rod plays a guiding role in the movement of the fourth connecting rod 55, ensuring that the fourth connecting rod 55 and the third connecting rod 51 are subjected to balanced force.

[0058] like Figure 2 As shown, the top of the guide plate 7 has a conical structure and is arranged below the screening plate 2. The soil particles screened from the screening plate 2 fall on the guide plate 7 and then fall into the box body 1 along with the guide plate 7. The setting of the guide plate 7 prevents the soil particles from falling directly on the screw rod 53, thereby preventing the soil particles from affecting the coordination between the screw rod 53 and the fourth connecting rod 55.

[0059] The working principle of this embodiment is:

[0060] The soil-spraying device of this embodiment adds soil into the box body 1 from the feed port 1a and drops it on the screening plate 2. The vibration mechanism 3 drives the screening plate 2 to vibrate, and fine soil falls to the bottom of the box body 1 through the through hole 2b, while larger soil remains in the screening plate 2. At this time, the first driving mechanism 5 drives the crushing roller 4 to move, and the crushing roller 4 rotates itself to crush the soil on the screening plate 2. The vibration mechanism 3 drives the screening plate 2 to vibrate again, and the above steps are repeated to complete the screening and crushing of the soil.

[0061] Embodiment 2:

[0062] This embodiment is improved on the basis of embodiment 1. The imported soil spraying device also includes a temperature and humidity sensor and a nitrogen, phosphorus and potassium sensor. The temperature and humidity sensor and the nitrogen, phosphorus and potassium sensor are arranged in the box 1, so as to quickly determine the soil nutrient conditions and add corresponding fertilizers when mixing the materials according to the above reference data.

[0063] The other claims of this embodiment are the same as those of Embodiment 1 and are not described in detail in this embodiment.

[0064] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
