Description

Technical Field

[0001] This invention relates to the field of agricultural pest and disease control technology, specifically to an agricultural pest and disease control spraying device. Background Technology

[0002] In the process of agricultural production, insects and mites can cause damage to crops. These pests and diseases are characterized by their wide spread and high risk, seriously threatening the safety of agricultural production. Control spraying devices are equipment that evenly spray pesticides, insecticides and other chemical agents onto the surface of crops. Through tiny droplets, the agents can adhere more effectively to the plant surface, thereby improving the control effect.

[0003] Patent CN222302850U discloses an agricultural pest control device. The device includes a base, a pesticide container, and a drive box. The pesticide container is fixedly connected to the top center of the base, and the drive box is also fixedly connected to the top center of the pesticide container. A motor is fixedly connected to the top of the drive box, and a second rotating shaft is fixedly connected to the motor drive. Second stirring blades are fixedly connected to the four sides below the second rotating shaft. This patented agricultural pest control device, by installing the drive box, rotating shaft, and stirring blades, automatically and thoroughly stirs the pesticide and water inside the pesticide container, preventing uneven stirring that could lead to excessively high pesticide concentrations that would affect the normal growth of crops. Simultaneously, by installing water pipes, a water pump, and atomizing nozzles, some of the pesticide solution is sprayed onto the back of crop leaves through the bottom atomizing nozzles, preventing pests such as aphids from attaching to the back of the leaves and thus limiting the control effect.

[0004] However, current agricultural pest and disease control devices have the following problems: when using these devices, it is difficult to spray pesticides on the top of tall crops, which makes the top of tall crops susceptible to pests and diseases. Therefore, we propose an agricultural pest and disease control spraying device. Summary of the Invention

The inner walls of the two I-shaped blocks are respectively provided with two infusion pipes of the liquid pump. The I-shaped blocks move upward against the infusion pipes of the liquid pump. Under the action of friction, the I-shaped blocks roll on the infusion pipes. The I-shaped blocks limit the infusion pipes and prevent the infusion pipes from getting tangled together.

[0011] According to the above technical solution, a grooved plate is fixed on the bottom surface of the transverse perforated plate. Sliding grooves are provided on both the front and back sides of the grooved plate. A T-shaped rod is slidably installed on the inner wall of the sliding groove of the grooved plate.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Please see Figures 1-8 One embodiment of the present invention is: an agricultural pest and disease control spraying device, comprising a column shell 1, an electric telescopic rod 2 fixedly installed on the inner wall of the column shell 1, a circular cover 3 fixedly installed on the top surface of the column shell 1, the top surface of the circular cover 3 having a square opening, a frame rod 4 fixedly installed on the telescopic top surface of the electric telescopic rod 2, the outer wall of the frame rod 4 being slidably connected to the inner wall of the square opening of the circular cover 3, a circular shell 5 fixedly installed on the top surface of the frame rod 4, a motor 6 fixedly installed at the bottom inside the circular shell 5, a circular cover 7 fixedly installed on the top surface of the circular shell 5, the rotating shaft of the motor 6 passing through and rotatably installed in the middle of the bottom surface of the circular shell 5, a horizontal plate 8 fixedly installed on the top surface of the rotating shaft of the motor 6, and a circular frame 9 fixedly installed on the top surface of the circular cover 7. Two shaft plates 10 are rotatably mounted through the top of the inner part of the cylindrical cover 7. The two shaft plates 10 are rotatably connected to the top surface of the cylindrical cover 7. The outer walls of the two shaft plates 10 are respectively on the movement trajectory of the outer wall of the horizontal plate 8. Two nozzles 11 are fixed at the ends of the two shaft plates 10 that are far apart from each other. Two plates 12 are fixed at the top surface of the rotating shaft of the two shaft plates 10. The bottom surface of the two plates 12 slides in contact with the top surface of the cylindrical cover 9. Springs 13 are fixed directly opposite the two plates 12. The two nozzles 11 are located in front of and behind the cylindrical cover 7. The two plates 12 are located above the cylindrical cover 9. A trolley 16 is fixed to the bottom surface of the cylindrical cover 1. A spring 13 is fixed to the top surface of the trolley 16. The liquid storage tank 17 is located to the right of the column housing 1. A battery box 18 is fixed to the right side of the top surface of the trolley 16. A square cover 19 is fixed to the top surface of the liquid storage tank 17, with an inlet on the top surface of the cover 19. A pump 20 is fixedly installed at the bottom inside the liquid storage tank 17. Two infusion pipes of the pump 20 pass through and slide on the bottom surface of the square cover 19. The two infusion pipes of the pump 20 are fixedly connected to the bottom surfaces of two nozzles 11. The frame rod 4 moves upward through the square opening of the circular cover 3. The frame rod 4 drives the circular housing 5 to move upward, the circular housing 5 drives the circular cover 7 to move upward, the circular cover 7 drives the circular frame 9 to move upward, and the circular frame 9 drives the shaft plate 10 to move upward. As the shaft plate 10 moves upward, it drives the nozzle 11 to move upward. During the rotation, the horizontal plate 8 contacts the shaft plate 10. Under the action of the squeezing force, the shaft plate 10 rotates in the circular frame 9. The shaft plate 10 drives the nozzle 11 to rotate. Under the action of the elastic force of the spring 13, the plate 12 returns to its original position. The plate 12 drives the shaft plate 10 to return to its original position. The shaft plate 10 drives the nozzle 11 to return to its original position, so that the nozzle 11 swings back and forth at a high position to spray the pesticide. This allows the nozzle 11 to spray the pesticide evenly on the top of tall crops, avoiding the situation where the pesticide is not sprayed on the top of tall crops when the agricultural pest and disease control spraying device is spraying pesticide, making the top of tall crops susceptible to pests and diseases. An anti-winding device 14 is provided on the top of the outer wall of the round shell 5. The anti-winding device 14 is used to prevent the two infusion tubes of the pump 20 from winding together. A circulation device 15 is provided on the left side of the anti-winding device 14. The circulation device 15 is used to recover the medicine dripped from the nozzle 11.

[0023] Because the spraying device cannot effectively spray pesticides over tall crops, the operator pushes a cart 16 into the field. The cart 16 supports the battery box 18 and the column housing 1. The operator activates the electric telescopic rod 2 in the column housing 1. The telescopic end of the electric telescopic rod 2 moves upward, which in turn moves the frame rod 4 upward. The frame rod 4 moves upward through the square opening of the circular cover 3, which in turn moves the circular housing 5 upward. The circular housing 5 then moves the motor 6 upward, and the shaft of the motor 6 moves the horizontal plate 8 upward. The circular housing 5 then moves the circular cover 7 upward, which in turn moves the circular frame 9 upward. The circular frame 9 then moves the shaft plate 10 upward, which in turn moves the nozzle 11 upward. The operator then activates the liquid pump 20 in the storage tank 17. The liquid pump 20 draws pesticide from the storage tank 17 and delivers the pesticide to the nozzle 11 through a delivery pipe. The nozzle 11 then sprays the pesticide. Dispensing the medicine, the operator simultaneously starts motor 6. The shaft of motor 6 begins to rotate clockwise, driving the horizontal plate 8 to rotate as well. During this rotation, the horizontal plate 8 contacts the shaft plate 10. Under the pressure, the shaft plate 10 rotates within the circular frame 9, causing the nozzle 11 to rotate. Simultaneously, the shaft plate 10 drives the plate 12 to rotate, which in turn drives the spring 13 to rotate. The spring 13 is stretched by the plate 12. When the horizontal plate 8 leaves the shaft plate 10, the spring 13... Under the action of force, the plate 12 resets, which in turn drives the shaft plate 10 to reset, and the shaft plate 10 drives the nozzle 11 to reset. This causes the nozzle 11 to swing back and forth at a high position to spray pesticide, ensuring that the nozzle 11 sprays pesticide evenly over the top of tall crops. This prevents the pesticide from not reaching the top of tall crops during use, thus avoiding the problem of tall crops being susceptible to pests and diseases when pesticides are not sprayed properly by agricultural pest and disease control spraying devices.

[0024] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, a ring-shaped straight frame 141 is fixed to the top of the outer wall of the circular shell 5, a frame 142 is fixed to the right side of the bottom surface of the ring-shaped straight frame 141, a horizontal perforated plate 143 is fixed to the bottom surface of the frame 142, a round rod 144 is fixed to the inner wall of the horizontal perforated plate 143, and I-shaped blocks 145 are rotatably installed on both the front and back sides of the round rod 144. The inner walls of the two I-shaped blocks 145 are respectively provided with two delivery pipes of the liquid pump 20. The horizontal perforated plate 143 drives the round rod 144 to move upward, and the round rod 144 drives the I-shaped blocks 145 to move upward. During the upward movement of the I-shaped blocks 145, the I-shaped blocks 145 move upward against the delivery pipes of the liquid pump 20. Under the action of friction, the I-shaped blocks 145 roll on the delivery pipes. The I-shaped blocks 145 limit the delivery pipes, so that the delivery pipes will not get tangled together, thus avoiding poor delivery of the liquid agent when the agricultural pest and disease control spraying device sprays the agent.

[0025] A grooved plate 146 is fixed to the bottom surface of the perforated plate 143. The front and back of the grooved plate 146 are provided with sliding grooves. A T-shaped rod 147 is slidably installed on the inner wall of the sliding groove of the grooved plate 146. A cylinder 148 is slidably installed on the outer wall of the T-shaped rod 147. A U-shaped block 149 is hinged to the bottom of the outer wall of the cylinder 148. The bottom surface of the U-shaped block 149 is fixedly connected to the top surface of the square cover 19. The T-shaped rod 147 slides upward in the cylinder 148. The cylinder 148 rotates to the left in the U-shaped block 149. The square cover 19 supports the U-shaped block 149. The T-shaped rod 147 slides to the left in the sliding groove of the grooved plate 146. The grooved plate 146 supports the perforated plate 143. When the operator pushes the cart 16, the perforated plate 143 will not shake violently. This avoids the perforated plate 143 shaking violently when the agricultural pest and disease control spraying device is spraying pesticides, which could cause the infusion tube in the I-shaped block 145 to fall off.

[0026] An L-shaped plate 151 is fixed to the left side of the trough plate 146, and a double tube plate 152 is fixed to the left side of the L-shaped plate 151. Two L-shaped rods 153 are fixed to the inner wall of the double tube plate 152. Two square boxes 154 are fixed to the left side of the two L-shaped rods 153 respectively. The two square boxes 154 are located below the two nozzles 11 respectively. Two hoses 155 are fixed through the bottom surface of the two square boxes 154. The ends of the two hoses 155 away from the two square boxes 154 are fixed through the top surface of the square cover 19. The pesticide dripping from the nozzles 11 enters the square boxes 154, and the pesticide in the square boxes 154 enters the hoses 155. The hoses 155 transport the pesticide into the storage tank 17. This avoids the inconvenience of recovering the pesticide dripping from the nozzles 11 when the agricultural pest and disease control spraying device is spraying pesticides, which would otherwise result in a lot of pesticide waste.

[0027] Two ring blocks 156 are fixed to the top of the outer wall of the two L-shaped rods 153 respectively. Two short rods 157 are fixed to the top surface of the two ring blocks 156 respectively. Two frame meshes 158 are fixed to the left end of the two short rods 157 respectively. The two frame meshes 158 are located above the two square boxes 154 respectively. The short rods 157 drive the frame meshes 158 to move upward. The frame meshes 158 filter the pesticide dripped from the nozzle 11, so as to avoid the pesticide being mixed with dust and other foreign matter when the agricultural pest and disease control spraying device sprays pesticides, resulting in poor quality of the recovered pesticide.

[0028] As the frame rod 4 moves the circular shell 5 upward, the circular shell 5 moves the annular straight frame 141 upward, the annular straight frame 141 moves the frame 142 upward, the frame 142 moves the horizontal perforated plate 143 upward, the horizontal perforated plate 143 moves the circular rod 144 upward, and the circular rod 144 moves the I-shaped block 145 upward. During the upward movement, the I-shaped block 145 moves upward against the infusion pipe of the liquid pump 20. Under the action of friction, the I-shaped block 145 rolls on the infusion pipe, limiting the infusion pipe and preventing it from getting tangled. This prevents the infusion pipes from getting tangled during use, thus avoiding the problem of poor pesticide delivery caused by the infusion pipes getting tangled when the agricultural pest and disease control spraying device is spraying pesticides.

[0029] As the frame 142 moves the perforated plate 143 upward, the perforated plate 143 moves the grooved plate 146 upward, and the grooved plate 146 moves the T-shaped rod 147 upward. The T-shaped rod 147 slides upward in the cylinder 148, and the cylinder 148 rotates to the left in the U-shaped block 149. The square cover 19 supports the U-shaped block 149, and the T-shaped rod 147 slides to the left in the groove of the grooved plate 146, so that the grooved plate 146 supports the perforated plate 143. When the operator pushes the cart 16, the perforated plate 143 will not shake violently. This prevents the perforated plate 143 from shaking violently during the use of the equipment, thus avoiding the problem of the infusion tube in the I-shaped block 145 falling off due to the violent shaking of the perforated plate 143 when the agricultural pest and disease control sprayer is spraying pesticides.

[0030] While the horizontal perforated plate 143 drives the grooved plate 146 to move upward, the grooved plate 146 drives the L-shaped plate 151 to move upward, the L-shaped plate 151 drives the double tube plate 152 to move upward, the double tube plate 152 drives the L-shaped rod 153 to move upward, the L-shaped rod 153 drives the square box 154 to move upward, and the square box 154 drives the hose 155 to move upward. When the nozzle 11 sprays the pesticide, the pesticide dripping from the nozzle 11 enters the square box 154, and the pesticide in the square box 154 enters the hose 155. The hose 155 transports the pesticide into the storage tank 17, preventing the inconvenience of recovering the pesticide dripping from the nozzle 11 during use. This avoids the problem of excessive pesticide waste caused by the inconvenience of recovering the pesticide dripping from the nozzle 11 when the agricultural pest and disease control spraying device is spraying pesticides.

[0031] As the double tube plate 152 moves the L-shaped rod 153 upward, the L-shaped rod 153 moves the ring straight block 156 upward, the ring straight block 156 moves the short rod 157 upward, and the short rod 157 moves the frame mesh 158 upward. The frame mesh 158 filters the pesticide dripping from the nozzle 11, preventing the pesticide dripping from the nozzle 11 from entering the square box 154 mixed with dust and other foreign matter during use. This avoids the problem of poor quality pesticide recovery caused by dust and other foreign matter mixed in when the agricultural pest and disease control spraying device sprays pesticides.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
