Description

Technical Field

[0001] The invention relates to the technical field of plant protection spraying, and in particular to a plant protection spraying structure used for soybean and corn strip composite planting. Background Art

[0002] In modern agricultural production, the strip-shaped composite planting model of soybeans and corn has gradually been promoted as an efficient way of land use. This planting model not only helps to improve the output efficiency of land, but also improves soil quality and reduces the occurrence of pests and diseases through the mutual benefit between crops. However, under this intensive planting model, traditional plant protection spray equipment is difficult to meet the needs of effective drug spraying inside the plant and on the back of the leaves.

[0003] Traditional spray devices usually use surface spraying, which mainly applies pesticides or fertilizers to the visible parts of the plant. This method is more effective for crops in an open environment, but it has obvious limitations for high-density planting patterns such as soybean and corn strip composite planting. Due to the close distance between crops and the lush growth of plants, the internal space is relatively closed, and conventional sprays are difficult to penetrate into the plant, and it is impossible to ensure that the drug evenly covers all target areas, especially the back of the leaves, which directly affects the effect of the drug and the success rate of pest control.

[0004] Therefore, we propose a plant protection spray structure for soybean-corn strip composite planting. This plant protection spray structure can spray deeply into the plant to ensure that the drug can reach and adhere to the inside of the plant and the back of the leaves, thereby ensuring the effect of the drug.

[0032] Example 1: A plant protection spray structure for soybean and corn strip composite planting, such as Figure 1-Figure 10As shown, it includes a fixed plate 1, a mounting frame 2, wheels 3, a push plate 4, a sliding plate 5, a cross pipe 6, a connecting pipe 7, a first water tank 8, a connecting head 9, a spray pipe 10, an electric slide rail 11, a first baffle 12, a second water tank 13, a spray frame 14, an infusion tube 15, a first torsion spring 16, a leaf blowing assembly and a shielding assembly. The left and right sides of the fixed plate 1 are fixedly connected to the mounting frame 2, the front and rear parts of the mounting frame 2 are rotatably connected to the wheels 3, and the front and rear parts of the mounting frame 2 are fixed. A push plate 4 is connected to prevent soybean branches and leaves from being involved in the wheel 3. The front side of the push plate 4 is inclined. The push plate 4 covers the front side of the wheel 3. The rear of the fixed plate 1 is slidably connected to two left and right sliding plates 5. The upper part of the sliding plate 5 is fixedly connected to a transverse tube 6. The transverse tube 6 is connected to a connecting tube 7. The fixed plate 1 is fixedly connected to a first water tank 8. The first water tank 8 has a water pump inside. The tail end of the connecting tube 7 is connected to the water pump in the first water tank 8. A connector 9 is fixedly connected to the middle of the transverse tube 6. The left and right parts of the tube 6 are slidably connected with connectors 9, which are connected to the transverse tube 6, and the lower side of the connector 9 is connected with a spraying tube 10. Two electric slide rails 11 are fixedly connected to the rear part of the lower side of the fixed plate 1, and the electric slide rails 11 are slidably connected to the adjacent sliding plates 5. The left and right parts of the lower side of the fixed plate 1 are fixedly connected with a first baffle 12 for preventing soybean spray from drifting onto corn. The fixed plate 1 is fixedly connected with a second water tank 13, and the second water tank 13 has a water pump inside. The lower side of the fixed plate 1 is rotatably connected with a spray frame 14, and an infusion pipe 15 is connected between the spray frame 14 and the second water tank 13, and the infusion pipe 15 is connected to the water pump in the second water tank 13. The left and right sides of the spray frame 14 are connected to the fixed plate 1 with a first torsion spring 16. The fixed plate 1 is provided with a leaf blowing component for blowing soybean branches and leaves upward so that the spray can reach and adhere to the inside of the plant. The transverse tube 6 and the fixed plate 1 are provided with a shielding component for preventing corn spray from drifting onto soybeans.

[0033] When using the device, the staff controls the sliding plate 5 to slide through the electric slide rail 11, thereby driving the horizontal pipe 6, the connecting head 9 and the spraying pipe 10 to move outward, and then the staff controls the wheel 3 to move in the gap between the soybeans and the corn. The soybeans are located on the lower side of the fixed plate 1, and the corns are located on the left and right sides of the fixed plate 1. The spraying pipe 10 extending outward extends into the interior of the corn plant. The medicine in the first water tank 8 is sucked into the connecting pipe 7 by a water pump and then input into the horizontal pipe 6, and then enters the spraying pipe 10 through the connecting head 9. The medicine is evenly sprayed into the interior of the corn plant through the spraying pipe 10, so that the entire corn plant is in contact with the medicine from top to bottom. The medicine in the second water tank 13 is sucked into the infusion pipe 15 by a water pump, and then sprayed to the On the soybean plant, when spraying the soybean, the soybean branches and leaves are blown upward by the leaf blowing assembly so that the spray can reach and adhere to the inside of the soybean plant. During spraying, the first baffle 12 can block the soybean medicine from drifting to the corn, and the shielding assembly can prevent the corn spray from drifting to the soybean. When the device moves forward, the push plate 4 can push the soybean branches and leaves inward or upward to prevent the soybean branches and leaves from being drawn into the wheel 3. After the use of the device is completed, the staff controls the sliding plate 5 to slide in the opposite direction through the electric slide rail 11, thereby driving the cross tube 6, the connecting head 9 and the spray pipe 10 to move inward and retract. In this way, the medicine can be controlled to penetrate into the plant, ensuring that the medicine can reach and adhere to the inside of the plant and the back of the leaves, thereby ensuring the effect of the medicine.

[0034] like Figure 1 , Figure 6 and Figure 7 As shown, the leaf blowing assembly includes an electric push rod 17, an extrusion block 18, an air pump 19, an air pipe 20 and an air outlet frame 21. The electric push rod 17 is fixedly connected to the lower side of the fixed plate 1, and the telescopic end of the electric push rod 17 is fixedly connected to the extrusion block 18. The extrusion block 18 is wedge-shaped. The extrusion block 18 moves forward to extrude the spray frame 14 and rotates forward to change the spraying direction. The air pump 19 is fixedly connected to the front of the upper side of the fixed plate 1, and the air pipe 20 is connected to the left side of the air pump 19. The air outlet frame 21 is fixedly connected to the front of the lower side of the fixed plate 1, and the tail end of the air pipe 20 is connected to the air outlet frame 21.

[0035] In the initial state, the spray frame 14 is in a vertical downward spraying state, and the staff adjusts it according to the action mode of the medicine. If it is necessary to spray the medicine on the inside of soybean branches and the back of leaves, the staff controls the air pump 19 to operate. The air pump 19 operates to input air into the air outlet frame 21 through the air pipe 20. The air outlet frame 21 blows air forward to blow the soybean branches and leaves forward, thereby causing the branches and leaves of the soybean to leak out. While the air pump 19 is operating, it controls the electric push rod 17 to extend. The extension of the electric push rod 17 drives the squeezing block 18 to move forward. The squeezing block 18 moves forward to squeeze the spray frame 14 to rotate and tilt forward, and the first torsion spring 16 is deformed. The spray frame 14 sprays forward to spray the medicine on the internal branches and the back of the leaves of the soybean. When the spraying is completed, the staff controls the air pump 19 to close, and the electric push rod 17 will also drive the squeezing block 18 to move backward and no longer squeeze the spray frame 14. Under the action of the resetting of the first torsion spring 16, the spray frame 14 is reversed and reset. In this way, the soybean branches and leaves can be blown upward so that the spray can reach and adhere to the inside of the soybean plant.

[0036] like Figure 1 , Figure 8 , Fig. 9 and Fig.10 As shown, the shielding assembly includes a sliding sleeve 22, a frame 23, a double-sided rack 24, a long plate 25, a contact rod 26, a fixed sleeve 27, a second baffle 28, a first gear 29 and a second torsion spring 291. The left and right parts of the transverse tube 6 are both slidably connected with the sliding sleeves 22, the frame 23 is fixedly connected between the left and right sliding sleeves 22, the left and right sides of the frame 23 are both fixedly connected with the double-sided racks 24, the side of the frame 23 close to the sliding plate 5 is fixedly connected with the long plate 25, the left and right sides of the rear part of the fixed plate 1 are both fixedly connected with the contact rod 26, the long plate 25 moves and is pressed and matched with the contact rod 26 corresponding to the horizontal, the left and right ends of the transverse tube 6 are fixedly connected with the fixed sleeve 27, the front and rear sides of the fixed sleeve 27 are rotatably connected with the second baffle 28 for preventing corn spray from drifting onto soybeans, the upper part of the second baffle 28 is fixedly connected with the first gear 29, the first gear 29 is meshed with the adjacent double-sided rack 24, and the second torsion spring 291 is connected between the second baffle 28 and the fixed sleeve 27.

[0037] When the device is used, when the sliding plate 5 drives the cross tube 6 to move outward, the sliding sleeve 22, the frame 23, the double-sided rack 24, the long plate 25, the fixed sleeve 27, the second baffle 28 and the first gear 29 and other components will also move outward with the cross tube 6. When the long plate 25 moves to contact the contact rod 26, the long plate 25 is restricted by the contact rod 26 and no longer moves. The frame 23 and the double-sided rack 24 will not move with the cross tube 6. When the fixed sleeve 27, the second baffle 28 and the first gear 29 continue to move with the cross tube 6, the first gear 29 will mesh with the double-sided rack 24 and move forward. The first gear 29 rotates, the second baffle 28 rotates, the second torsion spring 291 is deformed, and the second baffle 28 rotates and opens to block the two sides of the corn to prevent the medicine sprayed from the spray pipe 10 from drifting onto the soybean. When the sliding plate 5 drives the horizontal tube 6 to move inward and retract, the sliding sleeve 22, the frame 23, the double-sided rack 24, the long plate 25, the fixed sleeve 27, the second baffle 28 and the first gear 29 will also move inward together. The long plate 25 moves inward and is no longer squeezed by the contact rod 26. At this time, under the action of the second torsion spring 291 resetting, the second baffle 28 will reverse and retract.

[0039] When using the device, when the wheel 3 rotates clockwise to drive the device forward, the third gear 303 will also rotate clockwise, thereby driving the second gear 302 to rotate counterclockwise. The second gear 302 rotates counterclockwise to drive the ring gear 301 to rotate counterclockwise. The ring gear 301 rotates counterclockwise to drive the rotating disk 30 to rotate counterclockwise. The rotating disk 30 rotates counterclockwise to drive one end of the toggle rod 31 to make a circular motion. Under the sliding guide of the sliding block 32, the other end of the toggle rod 31 will continuously move forward and then upward. The toggle rod 31 will lift up the fallen or tilted soybean seedlings so that the medicine can be sprayed on the soybean branches at the edge. At the same time, it can also prevent the fallen or tilted soybean seedlings from being crushed by the wheel 3.

[0040] like Figure 1 and Fig.13 As shown, it also includes an adjustment component for adjusting the spacing between the spray pipes 10, the adjustment component includes a threaded rod 33, a slider 34, a dual-axis motor 35, a fixed block 36 and a connecting block 37, two fixed blocks 36 symmetrically connected to the middle connecting head 9 are fixedly connected, the threaded rod 33 is rotatably connected to the upper side of the fixed block 36, the slider 34 is slidably connected to the fixed block 36, the threaded rod 33 is connected to the adjacent slider 34 by threads, the dual-axis motor 35 is fixedly connected between the upper sides of the left and right fixed blocks 36, the output shafts on both sides of the dual-axis motor 35 are fixedly connected to the adjacent threaded rods 33, and the connecting block 37 is fixedly connected between the slider 34 and the adjacent connecting head 9.
