Description

Technical Field

[0001] The present invention relates to the technical field of agricultural pest control, and specifically relates to an agricultural pest control spraying device. Background Art

[0002] In the process of agricultural production, insects and mites can cause damage to crops. These pests and diseases are characterized by wide spread and great danger, seriously threatening the safety of agricultural production. The control spraying device is a device that evenly sprays chemical agents such as pesticides and insecticides onto the surface of crops. Through tiny droplets, the agent can be more effectively attached to the plant surface, thereby improving the control effect.

[0003] The patent with the publication number CN222302850U discloses an agricultural pest control device. The agricultural pest control device includes a device base, a pesticide box body, and a drive box. The middle of the top of the device base is fixedly connected with a pesticide box body. The middle of the top of the pesticide box body is fixedly connected with a drive box. The inner top of the drive box is fixedly connected with a motor. The drive part of the motor is fixedly connected with a second rotating shaft. Four sides below the second rotating shaft are fixedly connected with second stirring blades. The agricultural pest control device provided by this patent makes the pesticides and water inside the pesticide box body automatically stir fully by installing a drive box, a rotating shaft, and stirring blades, preventing uneven stirring from causing too high a pesticide concentration to affect the normal growth of crops. At the same time, by installing a water pipe, a water pump, and an atomizing nozzle, part of the liquid medicine is sprayed onto the back of the crop leaves through the bottom auxiliary atomizing nozzle, preventing pests such as aphids from attaching to the back of the leaves, and the control effect is limited.

[0004] However, the current agricultural pest control devices have the following problems: When this agricultural pest control device is in use, since it is difficult to spray the agent above the tall crops when the spraying device sprays the agent, it will lead to the problem that the agent cannot be sprayed above the tall crops, resulting in the upper part of the tall crops being vulnerable to pests and diseases. Therefore, we propose an agricultural pest control spraying device. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an agricultural pest control spraying device, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An agricultural pest control spraying device includes a columnar shell. An electric telescopic rod is fixedly installed on the inner wall of the columnar shell. A round cover is fixed on the top surface of the columnar shell. A square opening is provided on the top surface of the round cover. The telescopic top surface of the electric telescopic rod is fixedly provided with a frame rod. The outer wall of the frame rod is slidably connected to the inner wall of the square opening of the round cover. A round shell is fixed on the top surface of the frame rod. A motor is fixedly installed at the bottom end inside the round shell. A round cover is fixed on the top surface of the round shell. The rotating shaft of the motor passes through and is rotatably installed in the middle of the bottom surface of the round shell. A horizontal plate is fixed on the top surface of the rotating shaft of the motor. A round frame is fixed on the top surface of the round cover. Two shaft plates are penetrated and rotatably installed at the top end inside the round frame. The two shaft plates are rotatably connected to the top surface of the round cover. The outer walls of the two shaft plates are respectively on the movement trajectories of the outer walls of the horizontal plate. Two spray nozzles are respectively fixed at the mutually remote ends of the two shaft plates. Two plate pieces are respectively fixed on the top surfaces of the rotating shafts of the two shaft plates. The bottom surfaces of the two plate pieces are in sliding contact with the top surface of the round frame. Springs are fixed on the opposite surfaces of the two plate pieces. The shaft plate drives the spray nozzle to move upward. During the rotation of the horizontal plate, it contacts the shaft plate. Under the action of the extrusion force, the shaft plate rotates in the round frame. The shaft plate drives the spray nozzle to rotate. Under the elastic force of the spring, the spray nozzle swings reciprocally at a high position to spray the medicament, enabling the spray nozzle to evenly spray the medicament above the tall crops.

[0007] According to the above technical solution, a trolley is fixed at the bottom surface of the columnar shell. A liquid storage tank is fixed on the top surface of the trolley. The liquid storage tank is located on the right side of the columnar shell. A battery box is fixed on the right side of the top surface of the trolley. A square cover is fixed on the top surface of the liquid storage tank. A liquid inlet is provided on the top surface of the square cover. A liquid pumping pump is fixedly installed at the bottom end inside the liquid storage tank. Two liquid delivery pipes of the liquid pumping pump pass through and are slidably installed at the bottom surface of the square cover. The two liquid delivery pipes of the liquid pumping pump are fixedly connected to the bottom surfaces of the two spray nozzles.

[0008] According to the above technical solution, the two spray nozzles are located in front of and behind the round cover, and the two plate pieces are located above the round frame.

[0009] According to the above technical solution, an anti - entanglement device is provided at the top of the outer wall of the round shell. The anti - entanglement device is used to block the entanglement of the two liquid delivery pipes of the liquid pumping pump. A recycling device is provided on the left side of the anti - entanglement device. The recycling device is used to recycle the medicament dripped by the spray nozzle.

[0010] According to the above technical solution, a ring - shaped straight frame is fixed at the top of the outer wall of the round shell. A frame is fixed on the right side of the bottom surface of the ring - shaped straight frame. A horizontal hole plate is fixed on the bottom surface of the frame. A round rod is fixedly installed on the inner wall of the horizontal hole plate. I - shaped blocks are rotatably installed on the front and back of the round rod. The two liquid delivery pipes of the liquid pumping pump are respectively arranged inside the two I - shaped blocks. The I - shaped block presses against the liquid delivery pipe of the liquid pumping pump and moves upward. Under the action of the friction force, the I - shaped block rolls on the liquid delivery pipe. The I - shaped block limits the liquid delivery pipe so that the liquid delivery pipes will not be wound together.

[0011] According to the above technical solution, a groove plate is fixed to the bottom surface of the transverse hole plate. Sliding grooves are provided on both the front and back surfaces of the groove plate. A T-shaped rod is slidably installed on the inner wall of the sliding groove of the groove plate. A cylinder is slidably installed on the outer wall of the T-shaped rod. A U-shaped block is hinged to the bottom of the outer wall of the cylinder. The bottom surface of the U-shaped block is fixedly connected to the top surface of the square cover. The T-shaped rod slides leftward in the sliding groove of the groove plate, so that the groove plate supports the transverse hole plate and prevents the transverse hole plate from shaking violently.

[0012] According to the above technical solution, an L-shaped plate is fixed to the left side of the groove plate. A double-tube plate is fixed to the left side of the L-shaped plate. Two L-shaped rods are fixed to the inner wall of the double-tube plate. Two square boxes are respectively fixed to the left sides of the two L-shaped rods. The two square boxes are respectively located below the two spray heads. Two hoses penetrate and are fixed to the bottom surfaces of the two square boxes. One ends of the two hoses away from the two square boxes penetrate and are fixedly connected to the top surface of the square cover. The medicament dripped by the spray heads enters the square boxes, the medicament in the square boxes enters the hoses, and the hoses transport the medicament into the liquid storage tank.

[0013] According to the above technical solution, two ring-shaped straight blocks are respectively fixed to the top parts of the outer walls of the two L-shaped rods. Two short rods are respectively fixed to the top surfaces of the two ring-shaped straight blocks. Two frame nets are respectively fixed to the left ends of the two short rods. The two frame nets are respectively located above the two square boxes. The frame nets filter the medicament dripped by the spray heads.

[0014] The present invention provides an agricultural pest control spraying device. It has the following beneficial effects: (1) In the present invention, through the cooperation of the column shell, the electric telescopic rod, the round cover, the frame rod, the round shell, the motor, the round cover, the horizontal plate, the round frame, the shaft plate, the spray head and the plate with the spring, the frame rod moves upward in the square opening of the round cover. The frame rod drives the round shell to move upward. The round shell drives the round cover to move upward. The round cover drives the round frame to move upward. The round frame drives the shaft plate to move upward. The shaft plate drives the spray head to move upward. The horizontal plate contacts the shaft plate during rotation. Under the action of the extrusion force, the shaft plate rotates in the round frame. The shaft plate drives the spray head to rotate. Under the elastic force of the spring, the spray head swings reciprocally at a high position to spray the medicament, so that the spray head evenly sprays the medicament above the tall crops, preventing the tall crops from not being sprayed with the medicament above and being vulnerable to pests and diseases.

[0015] (2) Through the setting of the anti-winding device in the present invention, the ring-shaped straight frame, the frame, the transverse hole plate and the round rod cooperate with the I-shaped block. The I-shaped block moves upward against the infusion tube of the liquid extraction pump. Under the action of the friction force, the I-shaped block rolls on the infusion tube. The I-shaped block limits the infusion tube, preventing the infusion tubes from winding together and causing poor medicament transportation of the infusion tubes.

[0016] (3) Through the setting of the anti-twisting device in the present invention, the groove plate, the T-shaped rod and the cylinder cooperate with the U-shaped block. The T-shaped rod slides leftward in the sliding groove of the groove plate, so that the groove plate supports the horizontal hole plate, preventing the horizontal hole plate from shaking violently and preventing the infusion tube in the I-shaped block from falling due to the violent shaking of the horizontal hole plate.

[0017] (4) Through the setting of the circulation device in the present invention, the L-shaped plate, the double-tube plate, the L-shaped rod and the square box cooperate with the hose. The medicament dripped by the nozzle enters the square box, the medicament in the square box enters the hose, and the hose transports the medicament into the liquid storage tank, preventing a large amount of medicament waste caused by inconvenient recovery of the medicament dripped by the nozzle.

[0018] (5) Through the setting of the circulation device in the present invention, the ring straight block and the short rod cooperate with the frame net. The frame net filters the medicament dripped by the nozzle, preventing the recovered medicament from being mixed with foreign matters such as dust and resulting in poor quality of the recovered medicament.

On the left side of the anti-winding device 14, a circulation device 15 is provided. The circulation device 15 is used to recover the medicament dripping from the spray head 11.

[0023] When the spraying device sprays the medicament, it is difficult to spray the medicament above the tall crops. When using the equipment, the operator pushes the trolley 16 into the farmland. The trolley 16 supports the battery box 18 and the column shell 1. The operator starts the electric telescopic rod 2 in the column shell 1. The telescopic end of the electric telescopic rod 2 starts to move upward. The telescopic end of the electric telescopic rod 2 drives the frame rod 4 to move upward. The frame rod 4 moves upward in the square opening of the round cover 3. The frame rod 4 drives the circular shell 5 to move upward. The circular shell 5 drives the motor 6 to move upward.

The shaft plate 10 drives the spray head 11 to rotate. At the same time, the shaft plate 10 drives the plate 12 to rotate. The plate 12 drives the spring 13 to rotate. The spring 13 is stretched by the plate 12. When the cross plate 8 leaves the shaft plate 10, under the elastic force of the spring 13, the plate 12 resets. The plate 12 drives the shaft plate 10 to reset. The shaft plate 10 drives the spray head 11 to reset, so that the spray head 11 swings back and forth at a high place to spray the medicament, making the spray head 11 evenly spray the medicament above the tall crops, preventing the situation that the medicament cannot be sprayed above the tall crops when the equipment is in use, and thus avoiding the problem that the tall crops are vulnerable to pests and diseases due to the inability to spray the medicament above the tall crops when the agricultural pest control spraying device sprays the medicament.

[0024] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, a ring 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 straight frame 141. A horizontal hole 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 hole plate 143. I-shaped blocks 145 are rotatably installed on the front and back of the round rod 144. Two liquid delivery pipes of the liquid extraction pump 20 are respectively arranged inside the two I-shaped blocks 145. The horizontal hole 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 push against the liquid delivery pipes of the liquid extraction pump 20 and move upward. Under the action of friction, the I-shaped blocks 145 roll on the liquid delivery pipes, and the I-shaped blocks 145 limit the liquid delivery pipes, so that the liquid delivery pipes will not be wound together, avoiding the situation that when the agricultural pest control spraying device sprays pesticides, the liquid delivery pipes are wound together and the liquid delivery of the liquid delivery pipes is poor.

[0025] A groove plate 146 is fixed to the bottom surface of the horizontal hole plate 143. Sliding grooves are respectively formed on the front and back of the groove plate 146. A T-shaped rod 147 is slidably installed on the inner wall of the sliding groove of the groove 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 leftward in the U-shaped block 149, the square cover 19 supports the U-shaped block 149, and the T-shaped rod 147 slides leftward in the sliding groove of the groove plate 146. The groove plate 146 supports the horizontal hole plate 143, so that when the operator pushes the cart 16, the horizontal hole plate 143 will not shake violently, avoiding the situation that when the agricultural pest control spraying device sprays pesticides, the horizontal hole plate 143 shakes violently and the liquid delivery pipes in the I-shaped blocks 145 fall off.

[0026] An L-shaped plate 151 is fixed to the left side of the groove plate 146. 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 respectively fixed to the left sides of the two L-shaped rods 153. The two square boxes 154 are respectively located below the two spray heads 11. The bottom surfaces of the two square boxes 154 penetrate and are fixed with two flexible hoses 155. One ends of the two flexible hoses 155 far away from the two square boxes 154 penetrate and are fixedly connected to the top surface of the square cover 19. The pesticides dripped by the spray heads 11 enter the square boxes 154, the pesticides in the square boxes 154 enter the flexible hoses 155, and the flexible hoses 155 convey the pesticides into the liquid storage tank 17, avoiding the situation that when the agricultural pest control spraying device sprays pesticides, the recovery of the pesticides dripped by the spray heads 11 is inconvenient and a large amount of pesticides are wasted.

[0027] On the top outer walls of the two L-shaped rods 153, two ring-shaped straight blocks 156 are respectively fixed. On the top surfaces of the two ring-shaped straight blocks 156, two short rods 157 are respectively fixed. On the left ends of the two short rods 157, two frame nets 158 are respectively fixed. The two frame nets 158 are respectively located above the two square boxes 154. The short rods 157 drive the frame nets 158 to move upward. The frame nets 158 filter the medicament dropped by the spray nozzles 11, avoiding the problem that the recycled medicament is mixed with foreign matters such as dust when the agricultural pest control spraying device sprays the medicament, resulting in poor quality of the recycled medicament.

[0028] While the frame rod 4 drives the circular shell 5 to move upward, the circular shell 5 drives the ring-shaped straight frame 141 to move upward, the ring-shaped straight frame 141 drives the frame 142 to move upward, the frame 142 drives the transverse hole plate 143 to move upward, the transverse hole plate 143 drives the round rod 144 to move upward, the round rod 144 drives the I-shaped block 145 to move upward. During the upward movement of the I-shaped block 145, the I-shaped block 145 abuts against the infusion tube of the liquid extraction pump 20 and moves upward. Under the action of friction, the I-shaped block 145 rolls on the infusion tube, and the I-shaped block 145 limits the infusion tube, preventing the infusion tubes from being wound together, so as to avoid the problem that the infusion tubes are wound together when the agricultural pest control spraying device sprays the medicament, resulting in poor medicament transportation by the infusion tubes.

[0029] While the frame 142 drives the transverse hole plate 143 to move upward, the transverse hole plate 143 drives the groove plate 146 to move upward, the groove plate 146 drives the T-shaped rod 147 to move upward. The T-shaped rod 147 slides upward in the cylinder 148, and the cylinder 148 rotates leftward in the U-shaped block 149. The square cover 19 supports the U-shaped block 149. The T-shaped rod 147 slides leftward in the chute of the groove plate 146, so that the groove plate 146 supports the transverse hole plate 143, preventing the transverse hole plate 143 from shaking violently when the operator pushes the cart 16, and avoiding the problem that the infusion tube in the I-shaped block 145 drops when the transverse hole plate 143 shakes violently when the agricultural pest control spraying device sprays the medicament.

[0030] While the transverse hole plate 143 drives the groove plate 146 to move upward, the groove 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 flexible hose 155 to move upward. When the spray head 11 sprays the medicament, the medicament dripped from the spray head 11 enters the square box 154. The medicament in the square box 154 enters the flexible hose 155, and the flexible hose 155 transports the medicament into the liquid storage tank 17, preventing the inconvenience of recovering the medicament dripped from the spray head 11 during the use of the equipment, thereby avoiding the problem of more waste of the medicament caused by the inconvenience of recovering the medicament dripped from the spray head 11 when the agricultural pest control spray device sprays the medicament.

[0031] While the double tube plate 152 drives the L-shaped rod 153 to move upward, the L-shaped rod 153 drives the ring straight block 156 to move upward, the ring straight block 156 drives the short rod 157 to move upward, the short rod 157 drives the frame net 158 to move upward, and the frame net 158 filters the medicament dripped from the spray head 11, preventing the medicament dripped from the spray head 11 from entering the square box 154 mixed with foreign matters such as dust during the use of the equipment, thereby avoiding the problem of poor quality of the recovered medicament caused by the recovered medicament being mixed with foreign matters such as dust when the agricultural pest control spray device sprays the medicament.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes an equivalent substitution or change, and should be covered by the protection scope of the present invention.
