Description

Technical Field

[0001] This utility model belongs to the field of agricultural implements technology, specifically relating to a herbicide spraying and drying device for soybean-corn strip intercropping. Background Technology

[0002] Corn-soybean strip intercropping is an agricultural planting technique that uses two rows of corn and two to four rows of soybeans planted in alternating strips. Through scientific configuration, it addresses light competition between crops, achieving stable corn yields while simultaneously increasing soybean production by one crop per mu (approximately 0.067 hectares). This technique is widely adopted. However, due to the alternating planting of soybeans and corn, traditional large-scale herbicide spraying equipment is difficult to apply. Furthermore, when spraying herbicides, the dense foliage of soybeans means that most of the sprayed herbicide will only reach the surface of the soybean leaves and branches, with only a small portion reaching the weeds between rows and below the leaves. This results in low application precision, poor weed control, and the herbicide can easily damage the soybeans. Summary of the Invention

[0003] In view of this, in order to solve the problems that most of the currently sprayed herbicides act on the surface of soybean branches and leaves, with only a small portion of the herbicide acting on weeds between rows and under branches and leaves, resulting in low application precision, poor weed control effect, and easy damage to soybeans by the herbicide, this invention provides a soybean-corn strip intercropping herbicide spraying and drying device.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A herbicide spraying device for soybean-corn strip intercropping includes a tank, on which rollers, a handrail, a support frame, and a liquid storage tank are installed. A base frame is fixedly mounted on the tank, and a pump set and an energy storage assembly are mounted on the base frame. The inlet end of the pump set is connected to the liquid storage tank, and the outlet end is connected to a spraying assembly. The spraying assembly includes a telescopic frame mounted on the base frame. The telescopic frame includes multiple telescopic units, each telescopic unit including two connecting rods hinged in the middle. Adjacent telescopic units are hinged together by a connecting shaft. Each lower connecting shaft is connected to a mounting seat, and a leaf-pulling assembly is hinged to the mounting seat. A bearing frame is provided on the base frame, and a bearing seat and a... A guide rod is provided, on which a movable part is slidably mounted. A threaded cylinder is connected to the movable part. Connecting shafts located at the top and bottom of the middle telescopic frame are fixedly connected to the threaded cylinder and a bearing seat, respectively. A screw is threadedly connected to the threaded cylinder, and the bottom end of the screw is rotatably connected to the bearing seat. The leaf-dispensing assembly includes a main rod body with an internal infusion tube. The top end of the main rod body is hinged to a mounting base. Each main rod body is equipped with a switch valve for controlling the connection of the infusion tube. A conical leaf-dispensing cover is installed at the bottom end of the main rod body. An atomizing nozzle connected to the infusion tube is installed inside the conical leaf-dispensing cover. The outlet end of the pump unit is connected to a main telescopic pipe, and the infusion tubes built into each main rod body are connected to the main telescopic pipe.

[0006] Based on the above technical solution, the present invention has made the following improvements:

[0007] Furthermore, the bottom of the telescopic frame is connected to fixed platforms on each connecting shaft on both sides of the bearing seat, and the top of the telescopic frame is connected to movable rings on each connecting shaft on both sides of the threaded cylinder. A second guide rod slides through each movable ring, and the bottom end of each guide rod is fixedly connected to the corresponding fixed platform. C-shaped buckles matching the second guide rods are installed on the main rod. The leaf-pulling assembly can be rotated and lifted. By fastening the C-shaped buckles to the second guide rods, the leaf-pulling assembly can be retracted, thereby reducing the number of drooping leaf-pulling assemblies and making it suitable for soybean ridges with different row numbers.

[0008] Furthermore, a wedge is slidably mounted on the main rod. By moving the wedge, the depth to which the wedge is embedded in the mounting base is changed, altering the tilt angle of the main rod when the deflector assembly is lowered, thereby adjusting the height of the conical deflector cover.

[0009] Furthermore, an elastic support bar is installed at the bottom of the conical leaf-removing cover. The elastic support bar limits the movement of the conical leaf-removing cover from direct contact with the ground during the movement of the herbicide spraying device. The contact between the elastic support bar and the ground determines the height, allowing the operator to better control the lifting height of the handle, thereby facilitating the conical leaf-removing cover to more effectively remove soybean leaves.

[0010] Furthermore, a steering wheel is mounted at the top of the screw. The screw can rotate easily under the action of the steering wheel.

[0011] Furthermore, the inlet end of the pump unit is connected to a first connecting pipe, which is fitted with a female quick-connect coupling. The tank has a pre-drilled opening at the female quick-connect coupling position. The storage tank is connected to a male quick-connect coupling corresponding to the female quick-connect coupling. One end of the tank is open, and a slot is formed at the open end. A limit baffle is installed in the slot. Removing the limit baffle allows the storage tank to be pulled out of the tank, making disassembly convenient for replacing and replenishing the medication.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. By moving the herbicide spraying device between soybean rows, the conical leaf-removing cover extends under the branches and leaves between the soybean rows. The atomizing nozzles located inside the conical leaf-removing cover can directly act on the weeds and the ground under the branches and leaves when spraying the herbicide. As the herbicide spraying device moves forward, the conical leaf-removing cover can continuously remove branches and leaves, thereby preventing the soybean branches and leaves from blocking the weeds below and causing the herbicide to be sprayed directly onto the soybean leaves. The application precision is high, the weeding effect is good, and it is not easy to damage the soybean plants.

[0014] 2. By rotating the screw, the threaded cylinder can be lowered, causing the telescopic frame to unfold, thereby adjusting the spacing between each blade assembly to suit soybeans with different spacing. Attached Figure Description

The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1 , Figure 2 As shown, a herbicide spraying device for soybean-corn strip intercropping includes a tank 1, on which rollers 14, a handle 11, a support frame 13, and a storage tank 2 are installed. A base frame 3 is fixedly installed on the tank 1, and a pump set 32 ​​and an energy storage component 31 are installed on the base frame 3. The inlet end of the pump set 32 ​​is connected to the storage tank 2, and the outlet end is connected to a spraying component. The storage tank 2 is used to hold the herbicide. When the pump set 32 ​​is started, the herbicide in the storage tank 2 can be extracted and sprayed out through the spraying component.

[0030] Among them, such as Figure 8As shown, the inlet end of the pump unit 32 is connected to a first connecting pipe 33, and a quick-connect female connector 34 is installed on the first connecting pipe 33. A reserved opening 10 is provided on the tank box 1 at the position of the quick-connect female connector 34. A quick-connect male connector 21 corresponding to the quick-connect female connector 34 is connected to the storage tank 2. One end of the tank box 1 is open, and a slot is provided at the open end. A limit baffle 12 is installed in the slot. Pulling the limit baffle 12 can remove it from the slot. After removing the limit baffle 12, the storage tank 2 can be pulled out of the tank box 1. The storage tank 2 is easy to disassemble, making it convenient to replace and replenish the herbicide. After replacement, the storage tank 2 is put back into the tank box 1, and the installation is completed by pushing the storage tank 2 to connect the quick-connect female connector 34 and the quick-connect male connector 21.

[0031] like Figures 2-4 ,like Figures 8-10 As shown, the spraying assembly includes a telescopic frame 4 mounted on a base frame 3. The telescopic frame 4 includes multiple telescopic units, each of which includes two connecting rods 41 hinged in the middle. Adjacent telescopic units are hinged together by connecting shafts 42. Each connecting shaft 42 located at the bottom is connected to a mounting base 43, and a leaf-pulling assembly 5 is hinged to the mounting base 43. A support frame 35 is provided on the base frame 3. A bearing seat 351 and a first guide rod 36 are mounted on the support frame 35. A movable part 471 is slidably mounted on the first guide rod 36. A threaded cylinder 47 is connected to the movable part 471. The connecting shafts 42 located at the top and bottom of the middle telescopic frame 4 are fixedly connected to the threaded cylinder 47 and the bearing seat 351, respectively. Under the constraint of the support frame 35, the height of the lower end of the telescopic frame 4 cannot be changed when it is opened or closed. The threaded cylinder 47 is internally threaded with a screw 46. The bottom end of the screw 46 is rotatably connected to the bearing seat 351. When the screw 46 is rotated, the threaded cylinder 47 rises and falls. The rise and fall of the threaded cylinder 47 can drive the top of the telescopic frame 4 to rise and fall, thereby controlling the opening and closing of the telescopic frame 4. The top of the screw 46 is equipped with a steering wheel 461. Under the action of the steering wheel 461, the screw 46 can be easily rotated.

[0032] like Figure 5 , Figure 6 As shown, the leaf-dispensing assembly 5 includes a main rod 51 with a built-in infusion tube. The top end of the main rod 51 is hinged to the mounting base 43 via a pin 501. Each main rod 51 is equipped with a switch valve for controlling the connection of the infusion tube. A conical leaf-dispensing cover 52 is installed at the bottom end of the main rod 51. An atomizing nozzle 54 connected to the infusion tube is installed inside the conical leaf-dispensing cover 52. The outlet end of the pump set 32 ​​is connected to the main telescopic pipe 6. The infusion tubes built into each main rod 51 are all connected to the main telescopic pipe 6.

[0033] like Figures 3-5As shown, the bottom of the telescopic frame 4 is connected to fixed platforms 441 on each connecting shaft 42 on both sides of the bearing seat 351. The top of the telescopic frame 4 is connected to movable rings 442 on each connecting shaft 42 on both sides of the threaded cylinder 47. A second guide rod 45 is slidably inserted into each movable ring 442. The bottom end of each guide rod is fixedly connected to the corresponding fixed platform 441. C-shaped buckles 55 matching the second guide rods 45 are installed on the main rod body 51. The leaf-pulling assembly 5 can be rotated and lifted. By fastening the C-shaped buckles 55 to the second guide rods 45, the leaf-pulling assembly 5 can be retracted, thereby reducing the number of drooping leaf-pulling assemblies 5, thus making it suitable for soybean ridges with different row numbers.

[0034] like Figure 6 , Figure 7 As shown, a wedge block 502 is slidably installed on the main rod body 51. By moving the wedge block 502, the depth of the wedge block 502 embedded in the mounting base 43 is changed, thereby changing the tilt angle of the main rod body 51 when the leaf-dispensing assembly 5 is lowered, and thus adjusting the height of the conical leaf-dispensing cover 52.

[0035] like Figure 1 , Figure 5 As shown, the bottom of the conical leaf-removing cover 52 is equipped with an elastic support bar 53. The elastic support bar 53 limits the movement of the conical leaf-removing cover 52 to avoid direct contact with the ground during the movement of the herbicide spraying device. The contact between the elastic support bar 53 and the ground determines the height so that the operator can better control the lifting height of the handle 11, thereby making it easier for the conical leaf-removing cover 52 to better remove the soybean leaves.

[0036] In use, pour the prepared herbicide solution into the storage tank 2, then place the storage tank 2 into the tank 1 and connect the quick-connect female connector 34 to the quick-connect male connector 21. Next, select the appropriate leaf-removing component 5 based on the number of soybean rows. For example, if there are two rows of soybeans, place three leaf-removing components 5, positioning the two rows of soybean plants between the three components. Then, pull up the remaining leaf-removing components 5 so that the C-shaped clips 55 engage with the corresponding second guide rods 45, and close the valves on them. After placing the conical leaf-removing cover 52 on the leaf-removing component 5 under the soybean branches and leaves, start the pump unit 32 to draw the herbicide solution, which is then sprayed out through the atomizing nozzle 54, propelling the herbicide spraying device forward.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
