[0014] 1. The present invention arranges a penetration structure composed of a conical block and a soil-breaking block on the lower surface of the U-shaped cylinder, and utilizes the rotation of the second connecting pipe to make the penetration structure in the soil. When the sealing structure composed of a sealing plate and a supporting rod opens the vertical groove, the fertilizer in the U-shaped cylinder falls into the manufacturing space of the penetration structure, completing the spreading of the fertilizer and penetrating the fertilizer into the soil, thereby preventing the fertilizer from being lost due to rain or watering, and reducing the turning of the soil.

DETAILED DESCRIPTION

[0019] See also Figures 1 to 9 The intelligent agricultural fertilizer uniform spreading equipment provided by the present invention comprises a support plate 1, a material box 2 is installed on the upper surface of the support plate 1, a first connecting pipe 9 penetrating the support plate 1 is installed at the bottom of the material box 2, a plurality of discharge ports are provided on the annular surface of the first connecting pipe 9 away from the material box 2, a rotating pipe 11 is rotatably connected to the lower surface of the support plate 1, the rotating pipe 11 is sleeved on the annular surface of the first connecting pipe 9, a plurality of rectangular grooves are provided on the annular surface of the rotating pipe 11, a rectangular block 20 is slidably connected in the rectangular groove, and an elastic member is installed on the lower surface of the rectangular block 20 23, the elastic member 23 is a spring, the elastic member 23 is in a normal state, the end of the elastic member 23 away from the rectangular block 20 is installed in the rectangular groove, a plurality of rectangular blocks 20 are installed with a lower pressure ring 18 on one side away from the rectangular groove, an annular groove is provided on the annular surface of the lower pressure ring 18, a circular ring 17 is rotatably connected in the annular groove, a first rat tooth disk 21 and a second rat tooth disk 22 are installed on the lower surface of the lower pressure ring 18, the first rat tooth disk 21 is arranged on the outer side of the second rat tooth disk 22, and the length of the first rat tooth disk 21 is shorter than the length of the second rat tooth disk 22.

[0020] A pressure rod 5 is hinged on the upper surface of the support plate 1, and a movable ring 6 is slidably connected to the annular surface of the pressure rod 5. A circular hole is opened on the upper surface of the support plate 1, and an L-shaped rod 8 is inserted into the circular hole. One end of the L-shaped rod 8 is hinged to the movable ring 6, and the end of the L-shaped rod 8 away from the movable ring 6 is connected to the circular ring 17.

[0021] It should be noted that by pressing one end of the pressure rod 5 downward, the movable ring 6 can be driven to move on the annular surface of the pressure rod 5. At the same time, the height of the movable ring 6 is reduced and the position of the L-shaped rod 8 is driven to be lowered. When the position of the L-shaped rod 8 is lowered, the circular ring 17 is provided to drive the lower pressure ring 18 to move downward. The lower pressure ring 18 moves downward and then drives the first rat tooth disk 21 and the second rat tooth disk 22 to move downward.

[0022] A U-shaped cylinder 4 is provided on the lower surface of the support plate 1, and a third rat-tooth disk 15 is installed on the upper surface of the U-shaped cylinder 4, and the third rat-tooth disk 15 is in contact with the first rat-tooth disk 21. A second connecting tube 19 is sleeved on the annular surface of the first connecting tube 9, and a through opening 29 communicating with the feed port is opened on the upper side of the annular surface of the second connecting tube 19. A fourth rat-tooth disk 16 is installed on the annular surface of the second connecting tube 19, and the fourth rat-tooth disk 16 is in contact with the second rat-tooth disk 22.

[0023] When the lower pressure ring 18 moves downward and thus drives the first tooth plate 21 and the second tooth plate 22 to move downward, the first tooth plate 21 contacts and abuts against the third tooth plate 15, and the second tooth plate 22 contacts and abuts against the fourth tooth plate 16, so that the U-shaped tube 4 and the second connecting tube 19 move downward. Since the length of the first tooth plate 21 is shorter than that of the second tooth plate 22, after the lower pressure ring 18 drops to a certain height, the third tooth plate 15 no longer contacts the first tooth plate 21, and the U-shaped tube 4 no longer penetrates into the soil, but at this time the second tooth plate 22 is still in contact with the fourth tooth plate 16 and drives the second connecting tube 19 to move downward.

[0024] In some other embodiments, a plurality of vertical grooves are provided on the lower side of the annular surface of the U-shaped cylinder 4, and a sealing plate 27 is hinged in the vertical groove. The sealing plate 27 is hinged in the vertical groove. A supporting rod 28 is hinged on the side of the sealing plate 27 facing the inside of the U-shaped cylinder 4, and the end of the supporting rod 28 away from the sealing plate 27 is hinged to the second connecting tube 19. When the second connecting tube 19 still moves downward and the U-shaped cylinder 4 no longer penetrates into the soil, the second connecting tube 19 drives the supporting rod 28 to move downward, so that the sealing plate 27 is supported to open the vertical groove, so that the fertilizer in the U-shaped cylinder 4 enters the soil, and a conical block 25 is installed at the end of the second connecting tube 19 away from the first connecting tube 9, and a groove is provided on the lower surface of the U-shaped cylinder 4, and the conical block 25 is slidably connected in the groove. A plurality of soil-breaking blocks 26 are installed on the annular surface of the conical block 25, and the soil-breaking blocks 26 are in sliding contact with the U-shaped cylinder 4.

[0025] The second connecting pipe 19 moves downward, driving the soil-breaking block 26 and the conical block 25 to move downward, thereby creating space for the fertilizer to enter the soil and spread the fertilizer, while avoiding turning the soil to cause fertilizer loss.

[0026] A circular plate 24 is installed on the annular surface of the second connecting tube 19, and the circular plate 24 is in sliding contact with the inner surface of the U-shaped cylinder 4. The circular plate 24 is arranged on the upper side of the through opening 29. When the second connecting tube 19 moves downward and drives the sealing structure to open the vertical groove, the circular plate 24 moves downward to squeeze out the material in the U-shaped cylinder 4. When the second connecting tube 19 is reset and moves upward, the circular plate 24 can limit the amount of fertilizer entering the U-shaped cylinder 4 from the first connecting tube 9, thereby achieving uniform fertilizer spreading.

[0027] A vertical plate 37 is installed on the lower surface of the support plate 1, and a double-axis motor 35 is installed on one side of the vertical plate 37. A connecting rod 13 is installed on the end of the double-axis motor 35 away from the vertical plate 37, and a first bevel gear 14 is installed on the end of the connecting rod 13 away from the double-axis motor 35. A second bevel gear 12 is installed on the annular surface of the rotating tube 11, and the second bevel gear 12 is meshed with the first bevel gear 14. The end of the double-axis motor 35 away from the connecting rod 13 passes through the vertical plate 37 and is installed with a rotating rod 30. The annular surface of the rotating rod 30 is sleeved with a cylinder 34, and the end of the cylinder 34 away from the vertical plate 37 is installed with a moving wheel 3. The rotating rod 3 A moving groove is provided on the annular surface, a moving plate 32 is installed in the moving groove, a plurality of second elastic members 31 are installed on the side of the moving plate 32 facing the moving groove, the second elastic member 31 is a spring, the second elastic member 31 is in a normal state, the end of the second elastic member 31 away from the moving plate 32 is installed in the moving groove, a plurality of limiting grooves are provided on the side of the cylinder 34 facing the groove, a plurality of limiting rods 33 are installed on the end of the moving plate 32 away from the moving groove, the limiting rods 33 are inserted in the limiting groove, a contact rod 36 is provided above the moving plate 32, and the contact rod 36 is connected to the L-shaped rod 8.

[0028] One end of the dual-axis motor 35 provides kinetic energy for the moving wheel 3, and the other end provides kinetic energy for the rotation of the connecting rod 13. When movement is required, the output end of the dual-axis motor 35 rotates and drives the moving wheel 3 to rotate through the moving plate 32 and the limiting rod 33. When fertilizer needs to be spread, the L-shaped rod 8 is moved downward and drives the contact rod 36 to resist the moving plate 32, so that the limiting rod 33 is separated from the cylinder 34, and the L-shaped rod 8 moves downward to drive the pulling rod 7 to move downward, and drives the rotating tube 11 to rotate through the first bevel gear 14 and the second bevel gear 12. The rotation of the rotating tube 11 drives the rotation of the soil-breaking block 26 through the cooperation of the first rat tooth disk 21 and the second rat tooth disk 22, thereby making it easier for the U-shaped cylinder 4 to enter the soil.

[0029] An annular groove is provided on the annular surface of the second connecting tube 19, and a pulling ring 10 is rotatably connected in the annular groove. A pulling rod 7 is installed on the annular surface of the pulling ring 10, and the end of the pulling rod 7 away from the pulling ring 10 is connected to the L-shaped rod 8. When the fertilizer is spread, the pressure rod 5 is lifted again, thereby driving the second connecting tube 19 to rise. The rising position of the second connecting tube 19 drives the supporting rod 28 and the conical block 25 to rise. The rising position of the supporting rod 28 pulls the sealing plate 27 to close the vertical groove. The rising position of the conical block 25 into the groove can drive the U-shaped tube 4 to rise.

[0030] When the intelligent agricultural fertilizer uniform spreading device is used, the U-shaped cylinder 4 is first moved to the agricultural product where the fertilizer needs to be spread by the moving wheel 3, and then the pressure rod 5 is pressed down. The pressure rod 5 moves downward to drive the L-shaped rod 8 to move downward. The L-shaped rod 8 moves downward to drive the pulling rod 7 and the contact rod 36 to move downward. The contact rod 36 moves downward to squeeze the moving plate 32, so that the limiting rod 33 is separated from the cylinder 34, so that the dual-axis motor 35 no longer drives the moving wheel 3 to rotate, and the movement of the moving wheel 3 is stopped; Then, the end of the dual-axis motor 35 away from the moving wheel 3 is started to drive the connecting rod 13 to rotate. The connecting rod 13 rotates and transmits kinetic energy to the rotating structure through the first bevel gear 14 and the second bevel gear 12. When the pull rod 7 moves downward, the first houndstooth disc 21 on the rotating structure contacts the third houndstooth disc 15, and the second houndstooth disc 22 contacts the fourth houndstooth disc 16, thereby rotating the soil breaking block 26. As the pressure rod 5 is pressed downward, the conical block 25 and the soil breaking block 26 enter the soil to drill a hole. As the U-shaped cylinder 4 and the second connecting tube 19 move downward, the first tooth plate 21 gradually stops contacting with the third tooth plate 15, and the U-shaped cylinder 4 stops moving downward. At this time, the second tooth plate 22 is still in contact with the fourth tooth plate 16, and drives the second connecting tube 19 to continue to rotate downward. When the second connecting tube 19 rotates downward, it drives the conical block 25 to rotate downward, providing space for fertilizer spreading, and the second connecting tube 19 moves downward to drive the supporting rod 28 to squeeze the sealing plate 27 out of the vertical groove, so that the fertilizer in the U-shaped cylinder 4 is discharged from the U-shaped cylinder 4. At the same time, the downward movement of the second connecting tube 19 will also drive the circular plate 24 to move downward, which is more convenient for the discharge of the fertilizer in the U-shaped cylinder 4.

[0031] When the sowing is completed, the high pressure rod 5 is lifted again, and the position of the pressure rod 5 is raised to separate the first tooth plate 21 from the third tooth plate 15, and the second tooth plate 22 from the fourth tooth plate 16. At the same time, as the movement is performed, the pulling ring 10 drives the second connecting tube 19 to rise. After the position of the second connecting tube 19 is raised, the second connecting tube 19 is pulled to move upward. After entering the groove, the conical block 25 connected to the second connecting tube 19 drives the U-shaped tube 4 to move upward. When the notch on the second connecting tube 19 contacts the discharge port, the fertilizer in the material box 2 re-enters the U-shaped tube 4 through the first connecting tube 9 and the second connecting tube 19, so as to realize the uniform quantitative delivery of materials.
