Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a plant protection sprayer for intercropping soybeans and corns. Background Art

[0002] Soybean-corn intercropping leverages the interspecific benefits of the two crops. By rationally aligning the temporal and spatial patterns of the tall corn crop with the short soybean crop, it achieves efficient utilization of light, heat, water, and fertilizer resources, thereby increasing yields. Therefore, this soybean-corn intercropping model is widely adopted. However, in practice, because corn grows much taller than soybeans in the middle and late stages of its growth cycle, the corn planting belt forms two "retaining walls" on either side of the soybean planting belt. Traditional sprayers have fixed-length booms, which can easily interfere with corn stalks or require a second spraying cycle due to insufficient spraying width. Therefore, plant protection spraying is typically performed manually, sequentially within each soybean planting belt, resulting in low plant protection efficiency and high labor requirements.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] Specific implementation examples Figure 1 、 Figure 4 、 Figure 6 As shown, a plant protection sprayer for intercropping soybeans and corn includes a traveling vehicle 1, a medicine tank 2 arranged on the traveling vehicle 1, a spray rod 3 and a liquid pipe 5 with a nozzle 4 thereon. The liquid pipe 5 is connected to the spray rod 3 and communicated with the medicine tank 2 by means of a liquid pump. The key is that the sprayer also includes a group of fastening components 6, the spray rod 3 is cantilevered to both sides of the traveling vehicle 1, the liquid pipe 5 includes a main pipe 501 connected to the medicine tank 2 and a branch pipe 502 connected to the main pipe 501, the branch pipe 502 is connected to the traveling vehicle 1 and the spray rod 3, respectively, the nozzle 4 is arranged on the branch pipe 502, the spray rod 3 is hinged to the traveling vehicle 1 and fixedly connected by means of the fastening component 6, and the spray rod 3 has the freedom of swinging by means of the hinge shaft 7.

[0027] The medicine tank 2 is a double-pump double-medicine box, and the two medicine boxes are connected to the main pipe 501 by means of liquid pumps respectively.

[0028] In this embodiment, the hinge shaft 7 of the spray rod 3 is arranged vertically.

[0029] The fastening assembly 6 is a matching bolt and nut.

[0030] During operation, the fastening assembly 6 is opened to allow the spray rod 3 to rotate forward along the hinge shaft 7 and be unfolded from the traveling vehicle 1 to match the width of the soybean planting belt. The fastening assembly 6 is then used to lock the spray rod 3. The traveling vehicle 1 travels in a row of soybean planting belts 15. The spray rod 3 is installed at the front end of the traveling vehicle 1 and the spray range covers the width of the soybean planting belt 15. During the movement of the traveling vehicle 1, the liquid pump draws the liquid from the medicine tank 2 and supplies it to the liquid pipe 5 and is sprayed out by the nozzle 4, thereby realizing the spraying of the soybean planting belt 15, effectively avoiding the interference between the spray rod 3 and the corn stalks, or the reciprocating spraying caused by the spray range being insufficient to cover a soybean planting belt 15, effectively improving the efficiency of soybean plant protection spraying in the intercropping mode, and is particularly suitable for use in experimental fields of soybean planting belts of different widths.

[0031] After the branch pipe 502 is connected to the main pipe 501, it passes through the traveling vehicle 1 and is connected to the spray rod 3. A nozzle 4 is fixedly connected to the traveling vehicle 1 between the two spray rods 3. The nozzle 4 fixed to the traveling vehicle 1 is used to fill in the position that the nozzle 4 on the two spray rods 3 cannot spray, thereby preventing the occurrence of missed spraying areas and ensuring the prevention and control effect.

[0032] After the work is completed, the fastening assembly 6 is opened, and the spraying rod 3 is reversed and recovered along the hinge shaft 7, thereby reducing the overall width of the sprayer and facilitating traveling on the road outside the field. In this embodiment, the traveling vehicle 1 is a tractor.

[0033] Furthermore, the spray boom 3 is provided with a sleeve 17 having a tee joint thereon. The branch pipe 502 is a segmented structure connected via the tee joint. The nozzle 4 is connected to the branch pipe 502 via the tee joint. The tee joint is provided with a valve matching the nozzle 4. The nozzle 4 on the traveling vehicle 1 is located between the two spray booms 3.

[0034] Specifically, the branch pipe 502 is arranged in a wave shape by means of the connection with the three-way joint, the length of the spray rod 3 is greater than the sum of the sleeves 17 thereon, the height of the soybean plant gradually increases, and the soybean plants are relatively short in the seedling stage. The spray liquid is sprayed downward in a scattered manner by means of the nozzle 4. The distance between the nozzle 4 and the soybean plant is large, and the spray coverage range of the nozzle 4 is large. By closing the valve matching the nozzle 4 on the three-way joint at intervals, the spacing between the nozzles 4 that can perform spraying operations is increased to meet the spraying operation; when the soybean plant grows taller, the distance between the nozzle 4 and the soybean plant is shortened, and the branches and leaves of the soybean plant form a barrier to the spraying range of the liquid medicine, and the spray coverage range of the nozzle 4 becomes smaller. Therefore, by opening the valve on the three-way joint, the spacing between the nozzles 4 that can perform spraying operations can be shortened, so that the liquid medicine can be evenly sprayed on the soybean plant.

[0035] During operation, the density of the nozzles 4 capable of spraying on the spray boom 3 can be adjusted by switching the valve on the three-way joint to meet the needs of covering the soybean planting belt 15 with different crop heights, further preventing the occurrence of missed spraying areas and resulting in poor prevention and control effects, and at the same time avoiding excessive use of medicine caused by the fixed distance between the nozzles 4 capable of spraying.

[0036] Furthermore, the spray rod 3 is a telescopic rod, such as Figure 6 、 Figure 7 As shown, the telescopic rod includes a first rod 301 and a second rod 302 that are sleeved with each other, wherein the second rod 302 is sleeved in the first rod 301, and the outer end of the second rod 302 is a cantilevered end 303. The first rod 301 and the second rod 302 are both provided with a first positioning hole 10, and the second positioning hole 9 is provided on the first rod 301. The first rod 301 is hinged to the traveling vehicle 1, and the branch pipe 502 is connected to the first rod 301 and the second rod 302 extending from the first rod 301 by means of a sleeve 17. When the second rod 302 is retracted on the first rod 301, the spacing between the sleeves 17 installed on the part of the second rod 302 extending from the first rod 301 is small; when the second rod 302 is extended, that is, the part extending from the first rod 301 grows, the spacing between the sleeves 17 is increased by moving the sleeves 17 on the second rod 302; by extending and retracting the second rod 302 on the first rod 301 and adjusting the spacing of the sleeves 17 on the second rod 302, plant protection work of different widths of the soybean planting belt 15 can be met. Combined with the hinged structure of the spray rod 3, plant protection work of various widths can be achieved by swinging and extending the spray rod 3. On the other hand, during non-working period, the second rod 302 can also be retracted on the first rod 301 to shorten the length of the spray rod 3, thereby further improving the convenience of walking and storage of the plant protection sprayer.

[0037] Furthermore, the first rod 301, the second rod 302, and the sleeve 17 are respectively provided with a first positioning hole 10, and the first rod 301 and the second rod 302, and the second rod 302 and the sleeve 17 are respectively connected by the cooperation of the fastening component 6 and the first positioning hole 10, wherein the first positioning holes 10 are arranged at equal intervals along the axial direction of the spray rod 3, and the second rod 302 and the sleeve 17, and the first rod 301 and the second rod 302 are respectively connected by the cooperation of the fastening component 6 and the first positioning hole 10, Opening the fastening assembly 6 can make the second rod 302 extend and retract on the first rod 302. The position of the sleeve 17 on the second rod 302 is adjusted according to the extended length of the second rod 302, so that the spray range of the sprinkler 4 can evenly cover the soybean planting belt 15. The bolt is passed through the first positioning hole 10 overlapping between the second rod 302 and the sleeve 17, and the sleeve 17 is fixed to the second rod 302 by using the nut and bolt. The spraying work can be started by adjusting the switch of the valve on each three-way joint. The fixing structure is simple in structure and easy to adjust.

[0038] Furthermore, the traveling vehicle 1 is provided with a connecting frame 8, such as Figure 2 As shown, the first rod 301 of the spray boom 3 is hinged to the connecting frame 8, and a set of second positioning holes 9 arranged in a circumferential array along the hinge axis 7 are respectively provided on the first rod 301 and the connecting frame 8. Bolts are passed through the overlapping second positioning holes 9 on the first rod 301 and the connecting frame 8, and the spray boom 3 and the connecting frame 8 are fixedly connected with the help of nuts. Specifically, a connecting seat is provided on the first rod 301 and the connecting frame 1, and the connecting seat is a circular disc. The hinge axis 7 and the disc on the connecting frame 1 are coaxial and arranged vertically. The connecting seat of the connecting frame 1 is provided with two second positioning holes 9, and the connecting seat of the first rod 301 is provided with six second positioning holes 9.

[0039] Further, such as Figure 4 、 Figure 5 As shown, the traveling vehicle 1 is provided with a fixed square steel 11, and the connecting frame 8 is hooked on the fixed square steel 11 with the help of a U-shaped frame 14. The U-shaped frame 14 and the fixed square steel 11 are equipped with a third positioning hole 12. Before spraying, the connecting frame 8 is hooked on the fixed square steel 11, and the bolts are passed through the U-shaped frame 14 and the overlapping third positioning holes 12 on the fixed square steel 11 and the U-shaped frame 14 and the fixed square steel 11 are fixedly connected with the help of nuts to realize the installation of the spray rod 3. When the spraying is not in progress, the bolts and nuts can be opened to remove the spray rod 3 from the traveling vehicle 1, which is convenient for the storage of the spray rod 3 and the traveling vehicle 1.

[0040] Further, such as Figure 6 As shown, valves 13 are respectively provided on the branch pipes 502 between the nozzles 4 and the main pipe 501 . According to the different widths of the soybean planting belt 15 , the sprayer can also realize single-side spraying or double-side spraying by controlling the switch of the valve 13 .

[0041] Further, such as Figure 1 、 Figure 3 、 Figure 6 、 Figure 8As shown, an isolation plate 18 is provided on the overhanging end 303 of the second rod 302, and the isolation plate 18 is hinged to the overhanging end 303 by means of a hinge plate 19. The overhanging end 303 and the hinge plate 19 are both disc-shaped structures. The hinge plate 19 is located above the overhanging end 303 and is coaxially arranged with the disc-shaped structure of the overhanging end 303. The axis of the hinge plate 19 is arranged along the height direction. The isolation plate 18 can be adjusted in position as the second rod 302 is extended and contracted, and is always located between the soybean planting belt 15 and the corn planting belt 16 for drug isolation. When the spray boom 3 swings and the angle with the traveling vehicle 1 changes, the isolation plate 18 is adjusted by Rotate the hinged disc 19 to make the isolation plate 18 parallel to the traveling direction of the traveling vehicle 1, so as to meet the requirement of drug isolation between the soybean planting belts 15 and the corn planting belts 16 of different widths. A group of fourth positioning holes 20 are matched with the hinged disc 19 and the overhanging end 303. The fourth positioning holes 20 are arranged in a circular array along the hinged disc 19. The hinged disc 19 and the overhanging end 303 are fixedly connected by means of a fastening assembly 6. The drugs sprayed by the nozzle 4 adjacent to the overhanging end 303 are blocked by the isolation plate 18 and slide along the isolation plate 18, thereby preventing the drugs sprayed by the plant protection agency of the soybean planting belt 15 from entering the corn planting belt 16.
