Description
Technical Field
[0001] The utility model relates to the technical field of rice planting, in particular to a pesticide spraying device for rice planting. Background Art
[0002] Rice cultivation requires the prevention and control of a variety of pests and diseases. Usually, liquid pesticides are used in the form of fine atomized particles to inhibit or kill pathogens, insects and weeds that damage crops. Proper pesticide spraying can help increase crop yield and quality while reducing losses caused by pests and diseases.
[0003] The nozzles used in the pesticide spraying device for rice planting are usually fixed, which results in a small spraying range of the pesticide on the rice, thereby reducing the spraying efficiency. In addition, during the transportation process, the nozzles are usually unstable due to bumps, which makes them inconvenient to use.
[0004] The existing patent (publication number: CN216775900U) discloses a pesticide spraying device for rice planting, which realizes the effect of reciprocating movement back and forth through a diverter pipe, so that the diverter pipe drives the nozzle to move back and forth for spraying, effectively expanding the spraying range, improving the spraying effect and flexibility during use.
[0005] In response to the above problems, although the solution provided by the existing patent has the function of adjusting the position of the nozzle to increase the spraying range, the spraying range of the spraying device is limited, and the spraying device needs to continue to move inside the rice field. On the one hand, the effect of improving the pesticide spraying range is not significant enough, and on the other hand, the spraying device causes damage to the rice seedlings when moving. In the existing technology, large farms will use drones to assist the spraying device to operate in order to improve the spraying efficiency and spraying range, but the cost is relatively high and it is not applicable to some small farms.

[0029] The utility model provides a technical solution:
[0030] See also Figures 1 to 5 A pesticide spraying device for rice planting comprises a base 1 and a water tank 2 arranged on the upper side of the base 1, a plurality of hoses 3 are arranged on the upper side of the water tank 2, and a nozzle 4 is arranged at the other end of the hose 3, characterized in that: a lifting component 5 is arranged on the left side of the base 1, and a jacking component 6 is arranged on the upper side of the base 1;
[0031] The lifting component 5 includes a fixing seat 51 fixedly connected to the left side of the base 1, and a guide assembly 56 is provided on the upper side of the fixing seat 51;
[0032] The guide assembly 56 includes a first bracket 561 sleeved on the outside of the fixed seat 51, a second bracket 562 sleeved on the outside of the first bracket 561, a third bracket 563 sleeved on the outside of the second bracket 562, two roller groups 568 are arranged on the same side of the fixed seat 51, the first bracket 561 and the second bracket 562, the first connecting rope 54 and the second connecting rope 55 are both transmission-connected to the outside of the roller group 568, the left sides of the first bracket 561, the second bracket 562 and the third bracket 563 are fixedly connected with two lifting plates 564, the left sides of the fixed seat 51, the first bracket 561 and the second bracket 562 are fixedly connected with two pressure plates 565, and the opposite surfaces of adjacent lifting plates 564 and pressure plates 565 overlap each other after moving.
[0033] The left side of the fixed seat 51 is rotatably connected to a rotating wheel 52, and a servo motor 53 is provided on the other side of the rotating wheel 52, and the output end of the servo motor 53 is transmission-connected to a side of the rotating wheel 52 close to the servo motor 53, the fixed seat 51 is sleeved on the outside of the servo motor 53, and a first connecting rope 54 is wound around the outer surface of the rotating wheel 52, and a second connecting rope 55 is wound around the outer surface of the rotating wheel 52, and the roller group 568 consists of ten rollers, two of which are arranged on the left side of the fixed seat 51, four of which are arranged on the left side of the first bracket 561, and the remaining four rollers are arranged on the left side of the second bracket 562, and the five adjacent rollers are staggered with the other five rollers, and the first connecting rope 54 is located on the right side of the second connecting rope 55.
[0034] Two slide grooves 566 are provided on both sides of the fixed seat 51, on both sides of the first bracket 561 and on the front and rear sides of the second bracket 562. Slide blocks 567 are fixedly connected to the inner sides of the first bracket 561, the inner sides of the second bracket 562 and the inner sides of the third bracket 563. Several slide blocks 567 are slidably connected in several slide grooves 566 respectively.
[0035] The first bracket 561 , the second bracket 562 , and the third bracket 563 are all in a “U” shape, and the lengths of the first bracket 561 , the second bracket 562 , and the third bracket 563 increase from the inside to the outside.
[0036] By adopting the above technical solution, first, the base 1 will drive the water tank 2 to move through the roller below it. After reaching the farmland area, the medicine and water source are poured into the water tank 2 for mixing. The mixed medicine is transported by the hose 3 and sprayed through the nozzle 4. During this process, the servo motor 53 can be started to drive the rotating wheel 52 to rotate clockwise, so that the first connecting rope 54 and the second connecting rope 55 are gradually wound around the outside of the rotating wheel 52. When the first connecting rope 54 and the second connecting rope 55 are pulled, since the other ends of the first connecting rope 54 and the second connecting rope 55 are fixed on one side of the third bracket 563, the first connecting rope 54 and the second connecting rope 55 driven by the roller will drive the third bracket 563 to start moving upward, and drive the lifting component 6 and the nozzle 4 arranged above the lifting component 6 to lift upward. Subsequently, when the third bracket 563 moves upward, the two lifting plates 564 fixed on one side of the third bracket 563 also move with the third bracket 563. When the two lifting plates 564 on one side of the third bracket 563 and After the two pressure plates 565 on the same side of the second bracket 562 come into contact, the two pressure plates 565 will be lifted, so that the second bracket 562 will also start to move upward. Then, when the second bracket 562 moves upward, the two lifting plates 564 set on one side of the second bracket 562 will move to the bottom of the two pressure plates 565 on the side of the first bracket 561, and drive the first bracket 561 to move upward. Because the fixing seat 51 is fixedly set on the left side of the base 1, when the two lifting plates 564 on the side of the first bracket 561 come into contact with the two pressure plates 565 on the same side of the second bracket 562, the second bracket 562 will also start to move upward. When the first bracket 561 is below the two pressure plates 565 on one side of the fixed seat 51, the first bracket 561 will not be able to move upward any further, so that the nozzle 4 reaches the highest point. During the gradual upward lifting process of the nozzle 4, the medicine sprayed by the nozzle 4 will be sprayed on the rice around the base 1 from near to far. Since the medicine sprayed by the nozzle 4 will extend outward in a circular shape, the spraying range of the medicine will be further increased, thereby preventing the base 1 from moving back and forth between the rice, thereby reducing the phenomenon that the base 1 squeezes the rice and causes the rice to fall over.
[0037] Specifically, Figure 4 As shown, the lifting component 6 includes a column 61 fixedly connected to the upper side of the water tank 2, and a plurality of guide grooves are provided on the outer surface of the column 61. A movable plate 62 is slidably connected to the outer surface of the column 61 through the guide grooves, and the shape of the inner cavity protrusion of the movable plate 62 is adapted to the guide grooves.
[0038] A plurality of fixed blocks 63 are fixedly connected to the upper side of the movable disk 62. The sides of the plurality of fixed blocks 63 that are away from each other are hingedly connected to movable blocks 64 through hinges. A plurality of hoses (3) are respectively installed on the upper sides of the plurality of movable blocks 64.
[0039] Two guide grooves 65 are provided on the upper side of the fixed block 63, and the guide grooves 65 are inclined. Four movable latches 66 are hinged on the outer surface of the column 61, and the four movable latches 66 are respectively slidably connected in the four guide grooves 65, and the other side of the movable latch 66 is in sliding contact with one side of the movable block 64 close to the fixed block 63.
[0040] A return spring 67 is fixedly connected to the lower side of the movable latch 66 . The return spring 67 is arranged obliquely, and the other end of the return spring 67 is fixedly connected to the outer surface of the column 61 .
[0041] By adopting the above technical solution, first, when the nozzle 4 is lifted upward, the third bracket 563 will lift the movable disk 62, so that the movable disk 62 gradually moves upward on the outside of the column 61, and the fixed block 63 above the movable disk 62 will drive the movable block 64 connected thereto to move upward. Since the nozzle 4 is installed above the movable block 64, the nozzle 4 moves with the movable block 64. Then, before the nozzle 4 reaches the highest point, a plurality of movable latches 66 on the outside of the column 61 will be inserted into the guide groove 65 above the fixed block 63, and squeeze the movable block 64 after passing through the fixed block 63, so that the movable block 64 flips upward. At this time, the angle of the nozzle 4 will also change accordingly. After the direction valve of the nozzle 4 is changed, the parabola of the sprayed solution will change, so that the solution is sprayed to a farther distance, thereby increasing the spraying efficiency of the nozzle 4 on rice.
[0042] Working principle: First, the base 1 drives the water tank 2 to move through the rollers below it, and the medicine is transported to the nozzle 4 through the hose 3 and sprayed, then the servo motor 53 is started to drive the rotating wheel 52 to wind the first connecting rope 54 and the second connecting rope 55, and the first connecting rope 54 and the second connecting rope 55 driven by the rollers will drive the third bracket 563 to start moving upward and drive the nozzle 4 to lift upward. When the third bracket 563 moves upward, the two lifting plates 564 fixed on one side of the third bracket 563 also move with the third bracket 563, and lift the second bracket 562 after contacting the two pressure plates 565 on the same side of the second bracket 562, and then the two lifting plates 564 on one side of the second bracket 562 will move to the side of the first bracket 561 When the first bracket 561 is below the two pressure plates 565, the first bracket 561 will move upward, and the fixed seat 51 is fixed on the left side of the base 1. After the two lifting plates 564 on one side of the first bracket 561 contact the two pressure plates 565 on one side of the fixed seat 51, the first bracket 561 will not be able to continue to move upward. In the process of the nozzle 4 being lifted upward, the third bracket 563 will lift the movable disk 62, so that the movable disk 62 gradually moves upward on the outside of the column 61 and lifts the movable block 64 through the fixed block 63. Before the nozzle 4 reaches the highest point, a number of movable pins 66 on the outside of the column 61 will be inserted into the guide groove 65 above the fixed block 63, and squeeze the movable block 64 after passing through the fixed block 63, so that the movable block 64 flips upward.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
