Description

Technical Field

[0001] The invention belongs to the technical field of agricultural plant protection, and in particular relates to a pesticide spraying device for agricultural plant protection. Background Art

[0002] In the process of agricultural production, spraying pesticides and applying fertilizers are indispensable operations. Spraying pesticides to cover the surface of crops to prevent pests from eating crops, and spraying fertilizers to allow crops to obtain more nutrients to achieve good growth effects. At present, there are two spraying methods for different planting areas. When the planting area is small, the hand-held spraying method with a backpack liquid tank is adopted. When spraying between ridges, due to the large planting area, the spraying device needs to be loaded on an agricultural vehicle for spraying.

[0003] In order to ensure work efficiency, the spraying rod on the current spraying device is often long, and the structure of the spraying rod is relatively simple. It can only be extended and folded by simple lateral rotation. When the spraying rod is unfolded, its spraying range is fixed and cannot be adjusted. The spacing between ridges in different fields is different, and repeated spraying will occur on the route of agricultural vehicles, resulting in waste of liquid medicine.

[0004] In the prior art, there are patents with adjustable spraying range, but when adjusting the spraying range, most of them rely on lateral adjustment of the position of the water spray pipe to achieve the adjustment of the spraying range. Before and after the water spray pipe moves, its water spray hole will continue to discharge water, that is, when the positions of the two water spray pipes overlap, the two water spray pipes will continue to spray water, which will lead to excessive spraying of the liquid medicine, not only affecting the normal growth of crops, but also causing waste of liquid medicine. Although the opening and closing of the water spray hole can be controlled by a valve, the valve will undoubtedly increase the manufacturing cost. At the same time, after the liquid medicine is configured in the bucket, if it is not mixed evenly, precipitation will occur, affecting the effect of the application. In the prior art, a motor is often used to drive the stirring rod to rotate to achieve the mixing effect, and the use of a motor will increase the manufacturing cost. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a pesticide spraying device for agricultural plant protection, as described below.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The pesticide spraying device for agricultural plant protection provided by the present invention comprises a bottom frame and a water bucket, characterized in that: the water bucket is connected to the inner bottom of the bottom frame, three parallel water pipes are connected to one side wall of the bottom frame, a plurality of water outlet holes communicating with the inside of each water pipe are opened on the bottom side of each water pipe, and the two upper water pipes are slidably connected to the bottom frame along the long side direction of the bottom frame, the inner parts of the two upper water pipes are sleeved with inner tubes, the opposite ends of the two inner tubes extend to the outside of the water pipes and are fixedly connected to the two side walls of the bottom frame through support arms, and a driving component 1 for driving the two water pipes to move closer to or away from each other is provided on the side wall of the bottom frame;

[0008] A water pump assembly for conveying water to the three water pipes is arranged on the side wall of the water bucket, two stirring rods are rotatably connected to the inner bottom of the water bucket, and a driving assembly 2 is arranged on the inner bottom of the water bucket for driving the two stirring rods to rotate as the water flows.

[0009] When using the above agricultural plant protection pesticide spraying device, the bottom frame is installed and docked with the agricultural vehicle, the water bucket is filled with liquid medicine, and the water pump component is controlled to pump water from the inside of the water bucket and inject it into the lower water pipe and the upper two inner pipes respectively. While pumping water, the water flow drives the driving component 2 to operate, and the driving component 2 drives the upper two stirring rods to rotate and stir in the water to thoroughly mix the liquid medicine;

[0010] After entering the lower water pipe, the medicine liquid is directly sprayed downward. At this time, the positions of the three water pipes overlap. The medicine liquid entering the two upper inner tubes is blocked and cannot be sprayed out because there are no water outlet holes exposed. The two upper water pipes are driven away from each other by the driving component. At this time, the position of the inner tube inside does not move. With the movement of the water pipes, several water outlet holes are gradually connected with the inner cavity, and the medicine liquid entering the inner tubes is sprayed out from the exposed water outlet holes.

[0011] Preferably, a sealing ring is fixedly connected to the outer side of one end of the inner tube located inside the water pipe.

[0012] Preferably, two T-shaped slide grooves are formed through the side walls of the two upper water pipes, and two T-shaped slide bars slidably connected to the T-shaped slide grooves are fixedly connected to the side walls of the outer frame.

[0013] Preferably, the driving component comprises two gears rotatably connected to the side walls of the outer frame, and racks respectively meshing with the two gears are fixedly connected to the opposite surfaces of the two upper water pipes, and sprockets are fixedly connected to the outer sides of the two gears. The two sprockets are connected by a chain transmission, and a brake motor for driving one of the gears to rotate is fixedly installed on the side walls of the outer frame.

[0014] Preferably, a fan-shaped nozzle is arranged on the outer side of each water outlet.

[0015] Preferably, the side walls of the two upper water pipes are fixedly connected with extended arc plates, the side walls of the two water pipes are fixedly connected with water retaining films, and the water retaining films are in contact with the upper side surfaces of the extended arc plates, and the ends of the two water retaining films are fixedly connected with counterweight rods.

[0016] Preferably, the outward extension length of the upper extended arc plate is longer than that of the lower extended arc plate.

[0017] Preferably, the water pump assembly includes a water pump fixedly mounted on the water bucket, the water inlet end of the water pump extends to the inner bottom of the water bucket through a water inlet pipe, the water outlet end of the water pump is connected to a tee pipe 1, the two water outlets of the tee pipe 1 are respectively connected to the ends of the two inner pipes through connecting pipes, and the end of one of the connecting pipes is respectively connected to the inner pipe and the lower water pipe through a tee pipe 2.

[0018] Preferably, the second driving component includes two rotating shafts rotatably connected to the inner bottom of the bucket, and two stirring rods are respectively fixedly connected to the upper ends of the two rotating shafts, and the two rotating shafts are fixedly connected with fan wheels, the two fan wheels are staggered with each other, and the staggered point is adapted to the end of the water inlet pipe, and the two stirring rods are perpendicular to each other.

[0019] Preferably, a water collecting shell is provided on the outside of the intersection of the two impellers, and one end of the water collecting shell is connected to the end of the water inlet pipe and fixedly connected to the inner bottom of the bucket.

[0020] The beneficial effects are:

[0021] After entering the lower water pipe, the medicine liquid is directly sprayed downward. The medicine liquid entering the two upper inner tubes is blocked and cannot be sprayed out because there is no water outlet hole exposed. The two upper water pipes are driven away from each other by a driving component. At this time, the position of the inner tube inside is fixed. As the water pipes move, a number of water outlet holes are gradually connected with the inner cavity, and the medicine liquid entering the inner tube is sprayed out from the exposed water outlet holes. When no valve is used and the spraying range is adjustable, water is avoided from being sprayed in the area where the two upper water pipes overlap with the lowest water pipe, so that the effect of spraying as much as the amount is moved outward is achieved, thereby avoiding waste of medicine liquid.

[0022] When the water pump is working, the medicine liquid inside the water bucket is respectively input into the water pipe below and the two inner tubes above for spraying. At the same time, the medicine liquid inside the water bucket is pumped into the water inlet pipe to form a water flow, and the water flow will drive the two impellers to rotate, and at the same time drive the two stirring rods to rotate in the medicine liquid to mix the medicine liquid. Only one water pump is used to achieve the effect of mixing the medicine liquid while discharging water, thereby reducing manufacturing costs.

[0023] When the spraying liquid encounters wind, the liquid will drift after being sprayed out of the water pipe and cannot cover the surface of the crops well. When the wind blows towards the water-retaining film, the lower end falls due to the counterweight rod, reducing the deformation range of the water-retaining film. The scattered water mist adheres to the surface of the water-retaining film, gathers into water droplets and falls, avoiding drifting, thereby further improving the spraying effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0033] See also Figure 1-Figure 5 As shown, the present invention provides a pesticide spraying device for agricultural plant protection, comprising a bottom frame 1 and a water bucket 2, the water bucket 2 is connected to the inner bottom of the bottom frame 1, and three parallel water pipes 6 are connected to one side wall of the bottom frame 1, and a plurality of water outlets 10 communicating with the inside of each water pipe 6 are opened on the bottom side of each water pipe 6, and the two upper water pipes 6 are slidably connected to the bottom frame 1 along the long side direction thereof, and the inner parts of the two upper water pipes 6 are sleeved with inner tubes 7, and the opposite ends of the two inner tubes 7 extend to the outside of the water pipes 6 and are fixedly connected to the two side walls of the bottom frame 1 through support arms, and a driving component 3 for driving the two water pipes 6 to move closer to or away from each other is provided on the side wall of the bottom frame 1;

[0034] A water pump assembly 4 for conveying water to the three water pipes 6 is provided on the side wall of the water bucket 2. Two stirring rods 16 are rotatably connected to the inner bottom of the water bucket 2, and a driving assembly 2 5 for driving the two stirring rods 16 to rotate with the flow of water is provided on the inner bottom of the water bucket 2. When in use, the bottom frame 1 is installed and docked with the agricultural vehicle, the water bucket 2 is filled with liquid medicine, and the water pump assembly 4 is controlled to pump water from the inside of the water bucket 2 and inject it into the lower water pipe 6 and the upper two inner tubes 7 respectively. While pumping water, the water flow drives the driving assembly 2 5 to operate, and at the same time, the driving assembly 2 5 drives the upper two stirring rods 16 to rotate and stir in the water to thoroughly mix the liquid medicine;

[0035] After entering the lower water pipe 6, the medicine liquid is directly sprayed downward. At this time, the positions of the three water pipes 6 overlap, and the medicine liquid entering the upper two inner tubes 7 is blocked and cannot be sprayed out because there is no water outlet hole 10 exposed. The upper two water pipes 6 are driven away from each other by the driving component 13. At this time, the position of the inner tube 7 inside is fixed. With the movement of the water pipe 6, several water outlet holes 10 are gradually connected with the inner cavity, and the medicine liquid entering the inner tube 7 is sprayed out from the exposed water outlet holes 10.

[0036] See also Figure 3 As shown, a sealing ring 11 is fixedly connected to the outer side of one end of the inner tube 7 located inside the water pipe 6, which can make the contact between the inner tube 7 and the water pipe 6 closer and avoid liquid leakage, so that the liquid can only flow out from the water outlet 10. At the same time, the sealing ring 11 and the inner tube 7 block the water pipe 6, so that the water cannot flow out from the water outlets 10 where the two water pipes 6 are in the overlapping position, avoiding waste of liquid medicine.

[0037] See also Figure 2As shown, two T-shaped slide grooves 9 are penetrated on the side walls of the two upper water pipes 6, and two T-shaped slide bars 8 slidably connected to the T-shaped slide grooves 9 are fixedly connected to the side walls of the outer frame 1. The driving component 3 includes two gears 3a rotatably connected to the side walls of the outer frame 1, and the opposite surfaces of the two upper water pipes 6 are fixedly connected with racks 3d respectively meshing with the two gears 3a. The outer sides of the two gears 3a are fixedly connected with sprockets 3b, and the two sprockets 3b are connected by a chain 3c. A brake motor that drives one of the gears 3a to rotate is fixedly installed on the side wall of the outer frame 1. The arrangement of the machine 3e, the T-shaped slide groove 9 and the T-shaped slide bar 8 can make the water pipe 6 more stable when it moves horizontally. Through the cooperation of the above-mentioned structures, by controlling the brake motor 3e to drive a gear 3a to rotate, the gear 3a drives the water pipe 6 to move by engaging with the meshing rack 3d. At the same time, through the cooperation of the chain 3c and the sprocket 3b, the other gear 3a rotates at the same time. Through the transmission relationship between the structures, the two water pipes 6 can be moved closer to or farther from each other. At the same time, the arrangement of the brake motor 3e can keep the gear 3a fixed after stopping rotation to avoid accidental loosening.

[0038] Furthermore, a fan-shaped nozzle 12 is arranged outside each water outlet 10 , so that the liquid medicine can be sprayed out from the fan-shaped nozzle 12 under the action of pressure, and at the same time, it is fan-shaped after being sprayed, thereby increasing the spraying area of ​​a single water outlet 10 .

[0039] See also Figure 1 As shown, the side walls of the two upper water pipes 6 are fixedly connected with extended arc plates 13, and the side walls of the two water pipes 6 are fixedly connected with water retaining films 14, and the water retaining films 14 are in contact with the upper side surfaces of the extended arc plates 13. The ends of the two water retaining films 14 are fixedly connected with counterweight rods 15. The outward extension length of the upper extended arc plate 13 is longer than that of the lower extended arc plate 13. When the spraying liquid encounters wind, the liquid will drift after being sprayed out of the water pipes 6 and cannot cover the surface of the crops well. When the wind blows towards the water retaining film 14, the lower end falls due to the counterweight rod 15, reducing the deformation range of the water retaining film 14, and the scattered water mist adheres to the surface of the water retaining film 14, gathers into water droplets and falls, avoiding drifting, thereby further improving the spraying effect.

The wheels 5b are staggered with each other, and the staggered fan wheels 5b increase the contact area with the water flow, so that the fan wheels 5b can better rotate with the water flow, and the staggered point is adapted to the end of the water inlet pipe 4b. The two stirring rods 16 are perpendicular to each other, and the vertically arranged stirring rods 16 avoid collision during rotation. Through the above-mentioned structural coordination, when the water pump 4a is working, the medicine liquid inside the water bucket 2 is respectively input into the lower water pipe 6 and the upper two inner tubes 7 for spraying, and at the same time, the medicine liquid inside the water bucket 2 is pumped into the water inlet pipe 4b to form a water flow, and the water flow will drive the two fan wheels 5b to rotate, and at the same time drive the two stirring rods 16 to rotate in the medicine liquid to mix the medicine liquid.

[0041] Specifically, a water-collecting shell 5c is provided on the outside of the intersection of the two impellers 5b, and one end of the water-collecting shell 5c is connected to the end of the water inlet pipe 4b and is fixedly connected to the inner bottom of the bucket 2, so that the medicine inside the bucket 2 needs to pass through the water-collecting shell 5c when entering the water inlet pipe 4b, and the intersection of the two impellers 5b is located therein, and the water flow passes through it, effectively driving the two impellers 5b to rotate.
