Description

Technical Field

[0001] The invention relates to the technical field of pest control, and in particular to a pest control device. Background Art

[0002] Pest control is essential for maintaining crop health and ensuring food safety. Among the many control methods, chemical control is one of the most common and effective methods. Chemical control mainly relies on pesticide spraying to control the number of pests to reduce damage to crops. With the development of modern agricultural technology, pesticide spraying devices are also constantly innovating, from traditional manual sprayers to modern automatic sprayers and even drone spraying systems. These devices have greatly improved the efficiency and accuracy of pesticide use.

[0003] Rice and corn are among the most important food crops in the world and are of great significance to ensuring food security. However, these crops are often attacked by various pests during their growth, including major pests such as the rice borer and the corn armyworm. In order to protect crops from these pests, chemical control has become a common method, that is, spraying pesticides to control the number of pests.

[0004] A common problem encountered during the preparation and spraying of pesticides is that they are prone to precipitation, which can lead to uneven spraying and affect the control effect. When the solid components in the pesticide solution are not fully dissolved or dispersed, these components will gradually settle to the bottom of the container and form precipitation. If not stirred in time, these precipitations will lead to uneven spraying. Some areas may not be effectively protected due to insufficient pesticides, while other areas may be overused due to repeated spraying, which wastes resources and increases environmental risks. To ensure that crops are fully and effectively protected, measures must be taken to ensure that the pesticide solution remains uniform and consistent throughout the spraying process. Summary of the invention

[0005] The present invention aims to provide a pest control device to solve the problem of uneven spraying of existing pesticides.

[0006] A pest control device in the present scheme includes a self-propelled crawler vehicle, which is connected to a support frame, on which a spray box is arranged, in which a mounting box is arranged, in which a symmetrical left connecting rod and a right connecting rod are arranged, between which a linkage mechanism for making the left connecting rod and the right connecting rod deflect in opposite directions is arranged, the right connecting rod is tilted and rotatably connected to an inclined rod, the inclined rod is rotatably connected to a connecting shaft, the connecting shaft is fixedly connected to a rotating disk, a plurality of stirring blades are evenly distributed at the bottom of the rotating disk, a fixed rod is fixedly connected to the spray box, and the rotating disk is fixedly connected to a fixed rod. The fixed rod is connected with a rotating rod, the rotating rod passes through the fixed rod and is connected with a cam, a water outlet pipe is arranged in the spray box, the water outlet pipe is connected with a water pump, a water outlet is arranged on the spray box, the water outlet pipe passes through the water outlet, a hollow shaft is arranged on the outer sleeve of the water outlet pipe, a moving block is arranged on the hollow shaft and the outer sleeve, the cam and the moving block are abutted, a fixed cylinder is arranged near the water outlet of the spray box, the moving block is airtightly and slidably connected in the fixed cylinder, an elastic part is connected between one side of the moving block located in the fixed cylinder and the fixed cylinder, an annular jet nozzle is arranged on the wall of the spray box, and the jet nozzle ring is arranged outside the water outlet.

[0007] The working principle and beneficial effects of this solution are as follows: when in use, pesticides are added into the spray box, the person's two feet step on the left connecting rod and the right connecting rod respectively, the walking position of the spray box is controlled by controlling the self-propelled crawler vehicle, and then the left connecting rod and the right connecting rod are stepped on alternately. Since a linkage mechanism for making the left connecting rod and the right connecting rod deflect in opposite directions is provided between the left connecting rod and the right connecting rod, the right connecting rod will deflect in the opposite direction upward after the left connecting rod is stepped on, and the left connecting rod will deflect in the opposite direction upward after the right connecting rod is stepped on. When the right connecting rod deflects downward, it will drive the oblique rod connected to the rotation of the right connecting rod to rotate. Since the two ends of the oblique rod are respectively connected to the rotation of the left connecting rod and the connecting shaft The rotating shaft drives the rotating disk to rotate, and the rotating disk drives the stirring blade to rotate, so that the pesticide in the spray box can be evenly stirred, and the particles in the pesticide can be placed on the bottom, so that the sprayed pesticide is more evenly distributed. At the same time, the rotating disk drives the cam to rotate, and the cam rotates to push the moving block to move back and forth toward the water outlet. The moving block squeezes the gas inside the fixed cylinder and ejects the internal gas from the air jet port, so that the sprayed pesticide is sprayed outward, avoiding the sprayed pesticide from moving in other directions in the case of wind, resulting in failure to accurately spray the crops.

[0008] Further, the linkage mechanism includes a left incomplete gear and a right incomplete gear, the left incomplete gear is meshed with a left gear, the right incomplete gear is meshed with a right gear, the left gear and the right gear are both fixedly connected with a central gear, the two central gears are meshed, the left incomplete gear and the incomplete gear are both fixedly connected with a rotating shaft, the two rotating shafts respectively penetrate two opposite sides of the installation box, and the two rotating shafts are respectively fixedly connected with the left connecting rod and the right connecting rod. When the left connecting rod is stepped on, the left connecting rod drives the left incomplete gear to rotate, the left incomplete gear drives the left gear meshed with it to rotate, and the rotation of the left gear drives the central gear connected with it to rotate. Since the right gear is also connected with a central gear and the two central gears are meshed, the two central gears will rotate in opposite directions, so the rotation of the left gear will drive the right gear to reverse, and the right gear will drive the right incomplete gear to reverse, and finally the right incomplete gear can drive the right connecting rod to move up, so that it can be more labor-saving, and the right connecting rod automatically moves up when the left connecting rod is stepped on, and the left connecting rod automatically moves up when the right connecting rod is stepped on.

[0009] Furthermore, the left gear and the right gear are both connected to gear shafts, and the two central shafts are also respectively connected to the two gear shafts, and the gear shafts are both rotatably connected to the mounting box.

[0010] Furthermore, the meshing point of the two central gears is coaxial with the central axis of the rotating disk, and the central axis of the rotating disk, the axis of the rotating connection between the inclined rod and the connecting shaft, and the axis of the inclined rod and the right connecting rod intersect at one point. This arrangement can ensure smooth movement of the mechanism.

[0011] Further, the left connecting rod and the left connecting rod are both fixedly connected with a pedal. By stepping on the pedal, more effort is saved.

[0012] Furthermore, the stirring blade is arc-shaped, so that when stirring, there can be a force perpendicular to the arc-shaped surface of the stirring blade, which can better stir the pesticide inside.

[0013] Furthermore, the right connecting rod is connected to a generator, and the generator is used to supply power to the water pump. When the pedal connected to the right connecting rod is stepped on, mechanical energy is also provided to the generator, thereby converting the mechanical energy into electrical energy, and supplying power to the water pump. Thus, when the right connecting rod is stepped on, the moving block moves toward the water outlet, sprays air outward, and the water pump continues to pump water. When the pedal connected to the left connecting rod is stepped on, the generator stops generating electricity, and the water pump stops pumping water, thereby preventing the moving block from pumping back the pesticide when it moves back.

[0014] Furthermore, the diameter of the side of the jet port facing the inside of the spray box is smaller than the diameter of the side facing the outside of the spray box. This arrangement can better guide the direction of the pesticide.

[0015] Furthermore, the water outlet pipe is connected with a nozzle, so that the pesticide can be sprayed more evenly. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The meshing point of the two central gears 606 is coaxial with the central axis of the rotating disk 12. The central axis of the rotating disk 12, the axis of the rotating connection between the inclined rod 10 and the connecting shaft 11, and the axis of the inclined rod 10 and the right connecting rod 5 intersect at one point.

[0025] The self-propelled tracked vehicle 3 is a type of vehicle widely used in agriculture, construction, military and other fields, especially in farmland operations for spraying pesticides, fertilizing and other operations. When in use, add pesticides to the spray box 1, and the two feet of a person step on the left connecting rod 6 and the right connecting rod 5 respectively, and control the walking position of the spray box 1 by controlling the self-propelled tracked vehicle 3, and then alternately step on the left connecting rod 6 and the right connecting rod 5, and step on the pedal 7 connected to the left connecting rod 6, so that the left connecting rod 6 drives the left incomplete gear 602 to rotate, and the left incomplete gear 602 drives the left gear 603 meshing with it to rotate, and the rotation of the left gear 603 drives the central gear 606 connected to it to rotate. Since the right gear 604 is also connected to a central gear 606, and the two central gears 606 are meshed, the two central gears 606 will rotate in opposite directions, so the forward rotation of the left gear 603 will drive the right gear 604 to reverse, and the right gear 604 will drive the right incomplete gear 608 to reverse, and finally Finally, the right incomplete gear 608 can drive the right connecting rod 5 to move upward, so that the foot on the pedal 7 with the connecting rod automatically moves upward, which can save more effort, and the right connecting rod 5 automatically moves upward when the pedal 7 of the left connecting rod 6 is stepped on, and the left connecting rod 6 automatically moves upward when the right connecting rod 5 is stepped on.
