Description

Technical Field

[0001] The utility model relates to the technical field of spray equipment, in particular to the spraying of pesticides in a greenhouse, and specifically refers to an adjustable greenhouse single-track spray device. Background Art

[0002] In recent years, facility agriculture has developed rapidly in my country and has become an important way for farmers to increase their income. Taking the solar greenhouse as a typical example, it breaks through the traditional seasonal restrictions and creates suitable light, temperature, humidity and other conditions for the growth of crops through artificial means, realizing early or delayed harvest of crops, uninterrupted harvest throughout the year and continuous farming activities, and has been rapidly promoted in northern my country. However, compared with traditional agriculture, the problem of pests and diseases in facility agriculture is more serious. Most solar greenhouses are in a closed or semi-closed state, coupled with good temperature, humidity and soil conditions, which provide good conditions for the occurrence of pests and diseases, making the pests and diseases in the solar greenhouse present the characteristics of many types, high frequency of occurrence, strong harm and fast spread. Once greenhouse crops are affected by pests and diseases, not only will the yield and quality decline, but in severe cases there will be no benefits. If prevention and control measures are not taken in time, it will cause huge economic losses to farmers.

[0003] At present, domestic crop protection equipment mainly includes small manual or semi-automatic crop protection equipment such as small sprayers and backpack sprayers. Large and medium-sized crop protection equipment, such as tractor-drawn or suspended sprayers, small manual or semi-automatic crop protection equipment, are not ideal spraying equipment. Not only are they not highly automated, but they also pose health risks to sprayers. Large and medium-sized spray booms and self-propelled atomizers are mostly used for spraying in fields or orchards. When spraying pesticides with such crop protection machinery, pesticides are deposited too much in the plant canopy and too little in the lower layer of the plant, resulting in poor droplet penetration. In addition, due to the limited space in the greenhouse and the strict requirements on the size of the sprayer for plants in different growth cycles, the existing large and medium-sized sprayers cannot meet the actual use requirements. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an adjustable greenhouse single-track spray device, the height of the spray head of which is adjustable and can move along the guide rail by itself, thereby improving the operating efficiency and realizing the requirements for spraying medicine at different heights.

[0005] The utility model is realized through the following technical scheme, and provides an adjustable greenhouse monorail spray device, comprising a guide rail fixedly arranged in the greenhouse, and a traveling frame reciprocating along the guide rail, a telescopic mechanism extending downward is installed at the bottom of the traveling frame, a mounting plate is fixedly connected to the bottom of the telescopic mechanism, and a spray mechanism is arranged on the mounting plate; the spray mechanism comprises a circular arch plate fixedly connected to the mounting plate, and a plurality of nozzle brackets fixedly connected to the circular arch plate and uniformly arranged along the circumference of the circular arch plate, and each of the nozzle brackets is respectively installed with an atomizing nozzle.

[0006] This solution utilizes guide rails to provide support and movement guidance for the walking frame, thereby realizing self-propelled movement of the spray device. There is no need for the sprayer to work at close range, which greatly reduces the harm to the body and improves the efficiency of the spraying operation. By extending and retracting the telescopic mechanism up and down, spraying operations on plants at different heights are realized.

The nozzle bracket of this optimization solution has a simple structure, and the atomizing nozzle is installed at one end of the second connecting plate away from the first connecting plate, thereby avoiding interference of the circular arch plate with the installation and replacement operation of the atomizing nozzle.

[0009] As an optimization, the end of the second connecting plate away from the first connecting plate is fixedly connected to a third connecting plate perpendicular to the second connecting plate, and a universal base is fixedly connected to the third connecting plate by bolts; the universal base includes a bottom plate fixedly connected to the third connecting plate, and an arc plate located on one side of the bottom plate, the opening of the arc plate faces the bottom plate, and the two ends of the arc plate are respectively fixedly connected to the two ends of the bottom plate, and the arc plate is hingedly connected to the atomizing nozzle by a screw, and the screw is threadedly connected to fastening nuts located on both sides of the arc plate. This optimization scheme facilitates the adjustment of the spraying direction of the atomizing nozzle by setting a universal base. When adjusting, first loosen the fastening nut, then turn the atomizing nozzle to the desired angle, and then tighten the fastening nut.

[0010] As an optimization, the mounting plate includes a horizontal plate fixedly connected to the bottom plate of the telescopic mechanism by connecting bolts, and a vertical plate extending downward from the front or rear end of the horizontal plate, the vertical plate is fitted and fixedly connected to the circular arch plate, and the horizontal plate is provided with a long hole extending in the front-to-back direction for the connecting bolts to pass through. This optimization scheme sets the mounting plate to be L-shaped, and by setting the vertical plate, it is convenient to connect with the circular arch plate, and by setting the long hole on the horizontal plate, it is convenient to adjust the front-to-back position of the mounting plate, thereby realizing the adjustment of the front-to-back position of the atomizing nozzle.

[0011] As an optimization, an electrical box is fixed on the bottom surface of the horizontal plate, and the electrical box is located on the side of the vertical plate away from the atomizing nozzle. This optimization solution sets the electrical box on the bottom surface of the horizontal plate, making the overall structure of the spray device more compact, and at the same time uses the vertical plate to form a certain protection for the electrical box, reducing the droplets that drift to the electrical box.

[0012] As an optimization, the walking frame includes a crossbeam fixed to the top of the telescopic mechanism, and a U-shaped groove plate fixed to the top of the crossbeam and with an upward opening, a walking motor is installed on one side wall of the U-shaped groove plate, a driving gear is installed on the output shaft of the walking motor, and a rack extending in the front-to-back direction and meshing with the driving gear is fixed on the guide rail, and the driving gear is located on the upper side of the rack. The walking frame setting of this optimization solution provides the self-propelled power of the whole machine through the walking motor, and has a simple structure and convenient control.

[0013] As an optimization, the U-shaped groove plate is also equipped with lateral guide wheels respectively adapted to the left and right sides of the guide rail, and vertical guide wheels adapted to the bottom surface of the guide rail.

In order to improve the structural strength, the first connecting plate and the second connecting plate are fixedly connected by a reinforcing rib plate, one end of the reinforcing rib plate is welded to the first connecting plate, and the other end is welded to the second connecting plate.

[0031] The end of the second connecting plate away from the first connecting plate is fixedly connected to a third connecting plate perpendicular to the second connecting plate, and the third connecting plate is fixedly connected to a universal base 7 by bolts. Specifically, the universal base 7 includes a bottom plate fixedly connected to the third connecting plate, and an arc plate located on one side of the bottom plate, the opening of the arc plate faces the bottom plate, and the two ends of the arc plate are respectively fixedly connected to the two ends of the bottom plate, and the arc plate is hingedly connected to the atomizing nozzle by a screw rod, and the screw rod is threadedly connected to fastening nuts located on both sides of the arc plate.

By setting the arc plate, the adjustable angle of the atomizing nozzle is increased, and interference with the rotation of the atomizing nozzle is avoided.

[0032] The mounting plate includes a horizontal plate fixedly connected to the bottom plate of the telescopic mechanism by connecting bolts, and a vertical plate extending downward from the front end or rear end of the horizontal plate. The vertical plate is fitted and fixedly connected to the circular arch plate, thereby improving the stability of the circular arch plate. The horizontal plate is provided with a long hole for the connecting bolts to pass through and extending in the front-to-back direction, thereby facilitating the adjustment of the front-to-back position of the mounting plate, thereby adjusting the front-to-back position of the atomizing nozzle.

[0033] An electrical box 14 is fixed on the bottom surface of the horizontal plate, and the electrical box is located on the side of the vertical plate away from the atomizing nozzle. The control box is equipped with electronic control components including Zhongda Youkong PLC touch screen, 24V switching power supply and 4 intermediate relays, of which the 4 intermediate relays are 3 8-pin DC24V intermediate relays and 1 16-pin DC24V intermediate relay. The switching power supply provides a stable power supply for the PLC controller, and the common end of the 4 intermediate relays is externally connected to the output end of the PLC touch screen to control the operation of the travel motor 2 and the telescopic motor of the telescopic mechanism.

[0034] The U-shaped groove plate is also fixed with a mounting beam 12 extending forward, and a guide slider 10 and a front travel switch 11 are installed at the front end of the mounting beam. The guide slider is adapted to the guide rail, and the front travel switch 11 is located at the front side of the atomizing nozzle in the front-to-back direction. In order to improve stability, the guide slider and the mounting beam are also fixedly connected by a support rod 13, one end of the support rod is fixedly connected to the guide slider, and the other end is fixedly connected to the mounting beam. A rear travel switch is installed at the rear end of the walking frame, and a steel frame corresponding to the front travel switch and the rear travel switch is installed on the guide rail. When the adjustable greenhouse monorail spray device runs to the forward limit position and the backward limit position, the travel switch will touch the steel frame, and then transmit the signal to the electrical box. The electrical box 14 contains a circuit board and a remote control controller for controlling the travel motor, and then the travel motor will stop running, thereby improving the safety and reliability of the whole machine during operation. The electric telescopic platform is equipped with an upper stop point travel switch on its upper crossbeam and a lower stop point travel switch on the lower crossbeam. When the adjustable greenhouse monorail spray device performs fixed-point spraying, the telescopic motor starts to run. The adjustable greenhouse monorail spray device can control the motor operation according to the growth stage of the crop. When the electric telescopic platform reaches a distance that matches the growth stage of the crop, the telescopic motor will receive a signal from the travel switch and stop working, thereby improving the stability and durability of the electric telescopic platform.

[0036] When the adjustable greenhouse monorail spray device starts spraying, start the remote control and set the running speed of the travel motor 2 through the remote control, adjust the air compressor pressure to the appropriate air pressure, and adjust the power of the hydraulic pump to the appropriate gear. After the preparation work is completed, press the start button of the PLC touch screen in the control box, and the adjustable greenhouse monorail spray device starts to move forward at a uniform speed along the guide rail. The liquid medicine is dispersed by the gas in the atomizing nozzle 8 and sprayed from the nozzle. When the adjustable greenhouse monorail spray device moves forward for 8s, the travel motor 2 stops and brakes. At the same time, the telescopic motor starts to work, the electric telescopic stand starts to unfold, and the nozzle unit starts to extend downward to spray the bottom crops to ensure the droplet deposition amount and spraying efficiency.

After waiting for 0.1s, the electric telescopic stand starts to return, and the nozzle unit rises at a uniform speed to spray the vertical crops for the second time. When it reaches the upper dead point travel switch, the telescopic motor stops running. After waiting for 0.1s, the travel motor 2 continues to run and repeats the above operations.

[0037] When the adjustable greenhouse monorail spray device runs to the forward limit position, the front travel switch installed at the front end of the guide slider 10 touches the steel frame, the walking motor 2 stops and brakes, and then the remote control gives a backward command to the adjustable greenhouse monorail spray device, and then the adjustable greenhouse monorail spray device will return to the initial working position along the guide rail 1. When the rear travel switch of the adjustable greenhouse monorail spray device touches the steel frame installed in the greenhouse, the walking motor 2 stops and brakes, and then the reset button on the Zhongda Youkong PLC touch screen is pressed, and the spraying operation is completed.

[0038] The automatic spraying device provided in this embodiment has a nozzle that can be adjusted up and down, and the spray volume of the nozzle can also be adjusted by a throttle valve to adapt to the needs of current greenhouses and can perform spraying operations on plants in different growth cycles.

[0039] The adjustable greenhouse monorail spray device of this embodiment has the following advantages:

[0040] 1. The nozzle adopts atomizing nozzle 8 and the nozzles are evenly distributed at the front end of the electrical box 14. During the spraying operation, the nozzle can move up and down with the telescopic mechanism, which improves the penetration of the droplets and increases the deposition amount of the droplets inside the canopy and on the back of the leaves.
