Technical Field
The invention relates to a herbicide spraying device, in particular to a self-propelled chemical herbicide spraying device for a nursery.
Background
In the seedling growth period of the garden nursery, a large amount of weeds grow and propagate, so that the weeds compete for nutrients and water with seedlings to influence the growth of the seedlings, and are easy to parasitize various pests to influence the growth and development of the seedlings. At present, chemical weeding methods are mostly adopted for removing garden nursery weeds, chemical herbicides are used, and the weeds on nursery lands are eliminated by spraying, smearing, sand mixing and sealing, wherein the spraying of the chemical herbicides is the most effective method, and compared with the traditional physical weeding method, the method can reduce labor intensity and production cost. However, due to the lack of effective nursery mechanical facilities, the nursery herbicide is still sprayed in a traditional manner of manual negative-load pesticide spraying, the labor intensity is still high, the production efficiency is still to be improved, especially, most of the herbicide can damage the nursery stock while killing weeds, and especially, when the herbicide is sprayed on the growing parts such as branches and buds of the nursery stock, the normal growth of the nursery stock can be influenced, and the nursery stock can wither and die. Therefore, in actual production, the chemical herbicide is mostly sprayed at a low point, and the spraying point is arranged on the position close to the ground, so that the chemical herbicide aerosol formed by spraying is distributed below the lowest growth position of the nursery stock, and the adverse effect of the chemical herbicide on the nursery stock is reduced to the maximum extent. The harsh process requirement undoubtedly puts forward higher requirements for negative drug operators, which inevitably leads to further increase of labor intensity and further reduction of production efficiency, so that the development and the development of the convenient and efficient special herbicide spraying device for the nursery, which is suitable for the field of industrialized breeding and production of the nursery, are a directional topic for practically improving weeding production efficiency, reducing production cost and reducing labor intensity of workers.

Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings.
As shown in fig. 1, a self-propelled chemical herbicide spray device for nursery use includes a self-propelled vehicle carrier and a herbicide spray system.
The self-walking vehicle carrier comprises front wheels 1, rear wheels 2, a rear wheel support frame 6, an upper bearing surface 3, a lower bearing surface 4 and a walking control system 11 arranged on the lower bearing surface 4, the distance between the two rear wheels 2 is 130 cm according to design parameters aiming at a nursery cultivation base with the ridge distance of 65 cm and the highest height of nursery stock in a weeding period of 70 cm, the width of the upper bearing surface 3 is 150 cm, and the height from the ground is 90 cm.
The agent spraying system comprises a herbicide container 5, a supercharging device 12, a herbicide spraying rod 7 and a pressure reducing valve 14 arranged at a spray opening of the herbicide spraying rod 7; herbicide container 5 places on last loading face 3, and the design maximum drug-loading capacity is 800 liters, supercharging device 12 sets up under on loading face 4, supercharging device 12 and herbicide spraying pole 7 are respectively through seting up go up the hole on loading face 3 with 5 intercommunications of herbicide container, adjustment the length of herbicide spraying pole 7 makes spraying mouth keep 30 ~ 40 centimetres apart from ground distance, has and invert Y-shaped structure the first angle alpha of two spraying mouths of 7 spraying ends of herbicide spraying pole is 75, two crooked to the back slope spraying mouth with second angle beta between the 7 body of rod of herbicide spraying pole is 55.
The self-propelled vehicle carrier further comprises a spraying rod guard plate 8, the spraying rod guard plate 8 is installed at the front portion of the herbicide spraying rod 7, the distance between the end with the serrated edge and the ground is 8-15 cm, and a supporting rib plate 13 is vertically arranged at the rear portion.
When the self-propelled chemical herbicide spraying device for the nursery garden is used for production operation in the nursery garden, as shown in fig. 3, the front wheels 1 run in the middle furrow, the two rear wheels 2 respectively run in the furrows on the two sides of the middle furrow, and seedlings respectively pass through the lower part of the platform of the upper bearing surface 3, the platform of the lower bearing surface 4 and the space between the two rear wheels 2.
In the running process, as shown in fig. 4, the first bending part 20 pushes the weeds with a certain height at the front end to the first bending part, and as the first bending part 20 has a larger curvature radius, the contact surface between the first bending part 20 and the weeds is gradually increased, and when the contact surface reaches a certain degree, the bending part of the roots and stems of the weeds forms a small curvature radius area 23, and the roots and stems of the weeds can keep a vertical state inclined at a certain angle and have certain standing strength, so that the weed roots can be shoveled by the free-end serrated blade of the spray rod guard plate 8; meanwhile, as the lowest point of the first bending part 20 and the end with the sawtooth-shaped blade keep a certain length distance L in the horizontal direction, when the first bending part 20 is fully pressed on the weeds and the weeds form the optimal shoveling state, the sawtooth-shaped blade at the free end of the spraying rod guard plate 8 just contacts the roots of the weeds and shovels the weeds, thereby achieving the ideal shoveling effect; experiments prove that the length distance L of the lowest point of the first bending part 20 and the end with the sawtooth-shaped sharp edge in the horizontal direction is optimally 20-25 cm.
When the spraying rod guard plate 8 shovels the bent roots and stems of the weeds, the stems are shoveled or shoveled to damage the bent weeds, so that the bent weeds cannot stand upright again to shield the herbicide spraying opening, thereby clearing obstacles and ensuring that the chemical herbicide can be continuously and uniformly sprayed on the ground of a nursery.
The invention realizes that the herbicide spraying rod 7 extends to the ground to spray chemical herbicide, solves the problem that the chemical herbicide is sprayed to the growth part of nursery stock to influence the growth of nursery stock, simultaneously, the herbicide spraying rod 7 with two spraying ends bent towards the rear part and an inverted Y-shaped structure can lead the chemical herbicide to form fan-shaped atomized spray towards the rear part, atomized chemical herbicide with a certain area can be formed in an air layer directly contacted with the land of a nursery stock, and the atomized chemical herbicide forms continuous deposition on the ground of ridges and furrows along with the running of the self-propelled chemical herbicide spraying device for the nursery stock, thereby forming the chemical herbicide to be fully covered and sprayed on the spraying area and obtaining the ideal spraying and weeding effect.
