Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, specifically relating to a pesticide spraying device for corn cultivation. Background Technology

[0002] In corn cultivation, pesticide spraying is a crucial step in controlling pests and diseases and promoting crop growth. Corn has a long growth cycle, requiring farmers to spray pesticides and irrigate periodically. Currently, farmers mainly use backpack sprayers to spray pesticides on each corn stalk, which is very cumbersome. Some large-scale corn-growing areas use irrigation-type frame sprayers, but these still present the following problems:

[0003] (1) Inconvenient height adjustment: The height of corn plants varies significantly at different growth stages. Existing spraying devices are difficult to adjust the height quickly, resulting in uneven coverage of pesticides. When the corn plants are short, the pesticides are blown around by the wind, causing a lot of waste. When the corn plants grow taller, the height of the spraying device cannot reach the top of the corn. The leaves at the top of the corn are more tender, and pests will gather at the top of the corn plants to eat the leaves, affecting the corn yield.

[0004] (2) Poor stability: The field terrain is complex, and the traditional support only has one pole inserted into the soil, which is easy to tilt or loosen, affecting the stability of the spraying device.

[0005] To address the aforementioned problems, this utility model proposes an adjustable, highly stable, uniformly dispensing, and filtration-equipped pesticide spraying device for corn cultivation. Utility Model Content

[0006] To overcome the problems in the background art, this utility model provides a pesticide spraying device for corn cultivation.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0008] A pesticide spraying device for corn cultivation, comprising:

[0009] The support assembly includes a lower rod, an upper rod, and a fixed seat, wherein the upper rod is slidably fitted onto the lower rod, and the fixed seat is slidably installed on the lower part of the lower rod;

[0010] The liquid discharge assembly includes a buffer bottle, a dispensing component, and a U-shaped tube. The dispensing component is installed on the top of the upper rod and connected to the buffer bottle above it. The top of the buffer bottle is connected to an external water pipe through the U-shaped tube. The dispensing component consists of a horizontal dispensing tube, a threaded connecting sleeve connected to the buffer bottle at the top, and a threaded fixing sleeve fixed to the upper rod at the bottom. The connecting sleeve communicates with the inside of the dispensing tube.

[0011] The nozzle assembly includes a rotatable nozzle and nozzles. The nozzle is symmetrically fixed to both sides of the liquid distribution pipe by threads, and the nozzles are installed at equal intervals on the nozzle.

[0012] Furthermore, both the lower and upper rods have corresponding through holes, and the height is fixed by bolts and nuts. The bottom of the lower rod has a pointed tip for insertion into the soil.

[0013] Furthermore, the fixing base includes a sleeve, four connecting rods welded to the side of the sleeve, and a fixing nail. The sleeve is slidably installed on the lower rod, and the end of the connecting rod is provided with a round hole. The fixing nail passes through the round hole and is driven into the soil.

[0014] Furthermore, the dispensing tube, connecting sleeve, and fixing sleeve form a cross-shaped structure, the bottle mouth of the buffer bottle is inverted and installed onto the connecting sleeve by threads, and a lower liquid tube is formed inside the connecting sleeve to connect the dispensing tube.

[0015] Furthermore, the threaded diameter of the connecting sleeve is larger than the diameter of the lower liquid pipe opening, and a circular groove is opened at the center of the lower liquid pipe opening, in which a filter circular plate is fixedly installed by bolts.

[0016] The beneficial effects of this utility model are:

[0017] (1) Flexible and adjustable height adaptability: Through hole and bolt adjustment mechanism, the lower rod and the upper rod are fixed by multiple sets of through holes and bolts, which can realize stepless height adjustment within the range of 0.5 meters to 2 meters, accurately matching the plant height requirements of different growth stages such as corn seedling stage, jointing stage, and tasseling stage;

[0018] (2) Enhanced stability in multiple dimensions: The “umbrella-shaped” support structure is formed by four connecting rods, which can resist the tilting of the device caused by strong winds or mechanical vibrations. It is especially suitable for complex terrains such as hills and sandy areas. At the same time, the fixed seat can slide up and down along the lower rod. When the ground is uneven, the depth of the fixed nail (33) on one side can be adjusted to achieve overall vertical calibration of the device and avoid the tilting of the nozzle caused by terrain undulations.

[0019] (3) Optimization of drug liquid distribution uniformity and pressure balance: The fluid dynamics design of the cross-shaped liquid distribution component, the liquid distribution tube and the buffer bottle are vertically connected by a threaded connection sleeve. After the drug liquid is buffered by the buffer bottle, it is evenly distributed to both sides of the horizontal liquid distribution tube by the lower liquid tube, eliminating the problem of uneven flow caused by the pressure difference on one side of the traditional T-shaped liquid distribution tube. At the same time, because of the presence of the buffer bottle, the water pipe pressure fluctuation is avoided from directly impacting the nozzle, ensuring the nozzle pressure is stable and the atomization effect of the nozzles on both sides is consistent.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] See Figures 1 to 8This utility model discloses a pesticide spraying device for corn cultivation, comprising:

[0033] The support assembly includes a lower rod 1, an upper rod 2, and a fixing seat 3. The upper rod 2 is slidably fitted onto the lower rod 1, and the fixing seat 3 is slidably installed on the lower part of the lower rod 1. The lower rod 1 is a hollow metal tube with graduations (0.5m-2m) marked on its outer wall. The inner diameter of the upper rod 2 is slightly larger than the outer diameter of the lower rod 1. The two are slidably fitted together to achieve telescoping. The fixing seat 3 is made of engineering plastic and is fitted onto the lower part of the lower rod 1. It can slide up and down along the rod to adapt to the ground height.

[0034] The drainage assembly includes a buffer bottle 4, a dispensing component 5, and a U-shaped tube 6. The dispensing component 5 is installed on the top of the upper rod 2, and the buffer bottle 4 is connected above it. The top of the buffer bottle 4 is connected to an external water pipe 7 through the U-shaped tube 6. The dispensing component 5 consists of a horizontal dispensing tube 51, a threaded connecting sleeve 52 connected to the buffer bottle 4 at the top, and a threaded fixing sleeve 53 fixed to the upper rod 2 at the bottom. The connecting sleeve 52 is internally connected to the dispensing tube 51. The buffer bottle is made of transparent polyethylene with a volume of 2L. It has a water inlet at the top connected to the U-shaped tube 6, and is fixed to the dispensing component 5 at the bottom through the threaded connecting sleeve 52. The length of the horizontal dispensing tube 51 exceeds 20cm. The upper connecting sleeve 52 and the lower fixing sleeve 53 are both internally threaded. The three are welded into a cross shape. The dispensing tube 51 has symmetrical internally threaded interfaces on both sides.

[0035] The nozzle assembly includes a rotatable nozzle 8 and nozzles 9. The nozzle 8 is symmetrically fixed to both sides of the liquid distribution pipe 51 by threads. The nozzles 9 are installed at equal intervals on the nozzle 8. The rotatable nozzle 8 is made of aluminum alloy, is 1.2m long, and is screwed into both sides of the liquid distribution pipe 51 by threads. It can rotate 360° around the axis. Each nozzle 8 is equipped with 8 fan-shaped atomizing nozzles 9 with a spacing of 15cm. The nozzle 9 has an orifice diameter of 1.2mm and a flow rate of 0.5L / min.

[0036] Assembly steps for this device:

[0037] Insert the upper rod 2 onto the lower rod 1, align the through hole 11 according to the corn plant height (e.g., 0.8m during the seedling stage), insert the bolt and tighten the nut; slide the fixing seat 3 to a position where the lower rod 1 is 10cm from the ground, and unfold the four connecting rods 32; install the buffer bottle 4 upside down onto the connecting sleeve 52 of the dispensing component 5, ensuring a threaded seal; connect one end of the U-shaped tube 6 to the water inlet at the top of the buffer bottle, and connect the other end to the external pressurized water pipe 7; screw the two spray pipes 8 into the threaded interfaces on both sides of the dispensing pipe 51, and adjust the spray pipe angle to a 30° tilt.

[0038] During the corn tasseling stage (plant height 1.8m), adjust the upper rod 2 and fix the bolts; rotate the spray pipe 8 to a horizontal downward 15° position. After being buffered by the buffer bottle, the pesticide is evenly distributed to both sides of the spray pipe, covering the middle and lower leaves of the plant. The width of the mist on one side reaches 1.5m, and the average spraying time per acre is shortened to 20 minutes.

[0039] Example 2

[0040] This embodiment describes the height adjustment and soil fixing method. Both the lower rod 1 and the upper rod 2 have corresponding through holes 11. The height is fixed by bolts and nuts. The bottom of the lower rod 2 has a pointed tip 12 for insertion into the soil. The lower rod 1 and the upper rod 2 have a set of 8mm diameter through holes every 10cm, for a total of 15 sets, covering an adjustment range of 0.5m-2m. The bolts are M8 stainless steel bolts with anti-loosening nuts to ensure no shaking after tightening.

[0041] Example 3

[0042] In this embodiment, the installation of the fixing base 3 is described to adapt to the terrain. The fixing base 3 includes a sleeve 31, four connecting rods 32 welded to the side of the sleeve 31, and fixing nails 33. The sleeve 31 is slidably installed on the lower rod 1. The end of the connecting rod 32 is provided with a round hole 34. The fixing nail 33 passes through the round hole 34 and is driven into the soil.

[0043] Structural details:

[0044] Sleeve 31: The inner diameter matches the outer diameter of the lower rod 1. Four connecting rods 32, each 50cm long, are welded to the outside of the sleeve and are evenly distributed in an umbrella shape.

[0045] Fixing pin 33: 10mm in diameter, 40cm in length, with a spiral pattern at the end; round hole 34: 10mm in diameter, located at the end of connecting rod 32, for inserting fixing pin 33.

[0046] Slide the sleeve 31 to a position where the lower rod 1 is 15cm from the ground, and unfold the four connecting rods 32 to a horizontal position. Use a level to check if the connecting rods are horizontal. If they are not horizontal, adjust the soil penetration depth of the fixing nail 33 on one side individually. Pass the fixing nail 33 through the round hole 34 and hammer it into the soil to a depth of ≥30cm. Fix the two fixing nails 33 diagonally first, and then adjust the remaining two to ensure balanced force.

[0047] Example 4

[0048] In this embodiment, the liquid dispensing assembly is optimized. The dispensing tube 51, the connecting sleeve 52, and the fixing sleeve 53 form a cross-shaped structure. The bottle mouth of the buffer bottle 4 is inverted and installed onto the connecting sleeve 52 by threads. The connecting sleeve 52 forms a liquid drain tube 54 that connects to the dispensing tube 51.

[0049] The dispensing pipe 51, connecting sleeve 52, and fixing sleeve 53 are welded into a cross shape. The inner diameter of the lower dispensing pipe 54 is 8mm, which vertically connects the connecting sleeve 52 and the dispensing pipe 51, with the center line of the pipe opening coinciding with the axis of the dispensing pipe 51. The bottom of the buffer bottle 4 is directly connected to the connecting sleeve 52 to accelerate the flow of the liquid into the lower dispensing pipe 54. According to this scheme, in a contiguous cornfield (row length 100m), the pressure of the two spray pipes 8 is balanced, and the atomization of the end nozzles 9 is uniform, with no "dry zone" phenomenon. With the buffer bottle 4, the water flows equally into the spray pipes 8 on both sides. Since the water transported by the water pipe will have a phenomenon of fluctuating flow rate, and the air in the pipe will also make the water unable to be transported stably, the buffer bottle 4 can make the water in the spray pipe 8 spray out stably, which is 25% more efficient than the traditional T-type dispensing pipe 51.

[0050] In this embodiment, the thread diameter of the connecting sleeve 52 is larger than the pipe diameter of the lower liquid pipe 54. The lower liquid pipe 54 has a circular groove 55 at the center of the pipe opening, and a filter circular plate 56 is fixedly installed in the circular groove 55 by bolts.

[0051] The connecting sleeve 52 has a threaded opening diameter of 32mm, and the lower liquid pipe 54 has an opening diameter of 25mm, forming a cross-sectional area difference to initially intercept large particle impurities; the filter disc 56 is made of 304 stainless steel with a thickness of 2mm and is fixed in the disc groove 55 by M2 bolts. When it is necessary to disassemble and clean the inside of the liquid separator 5, close the external water pipe 7, unscrew the buffer bottle 4 to expose the connecting sleeve 52, use a wrench to loosen the fixing bolts of the filter disc 56, take out the filter screen, rinse with clean water and brush away the blockage.

[0052] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
