Background

With the development of modern science and technology, in the prevention and control of crop diseases and insect pests, various methods of biological prevention and control, physical prevention and control and chemical prevention and control exist, and the method plays an important role in increasing both production and income of agriculture. Chemical control is the most widely, conveniently and effectively applied control mode, and although certain pollution and toxic effects exist, the position of chemical control in agricultural production cannot be replaced temporarily. At present, the prevention and control of the diseases and the pests in China are mainly chemical prevention and control methods, namely, mechanical pesticide spraying is adopted to prevent and control the diseases and the pests. Although China is a big country for producing and using pesticides, the use efficiency of the pesticides is only 20% -40%. The serious backward of plant protection machinery is an important reason for causing the problems of low pesticide utilization rate, serious environmental pollution and the like.

Among these, the sprayers commonly used in plant protection machines have many problems. The traditional sprayer only has one spray head, is connected with a connecting rod, has small spraying area to the leaf surface, has low efficiency, and brings difficulty to the spraying work due to the overlong rod body. When spraying and applying pesticide, an operator only continuously advances and retreats to and the rotating rod body and then the direction of the spray head can be adjusted to fully apply pesticide to plants, the operation mode not only wastes time and labor but also wastes liquid medicine easily, and the operator also has the risk of personal poisoning, and particularly easily causes poisoning in the process of spraying high-efficiency and extremely toxic pesticide.

The spray heads are designed to be detachable, so that the whole spraying device can be maintained conveniently, and when one or more spray heads are in failure, the spray heads can be replaced conveniently, so that the use efficiency of the spraying device provided by the utility model can be greatly improved, and the cost is reduced; and the spray heads with different models can be selected at any time according to specific spraying requirements (such as different crops, different types and different using amounts of spraying liquid medicines), so that the applicability of the pesticide applying device provided by the utility model is greatly improved, the cost is reduced, and the pesticide applying device is convenient for operators to select.

In a preferred embodiment, as shown in fig. 2, in order to make the most of the connection rod 10, to maximize the spray area, to prevent the spray head 20 from spraying toward a person, and to reduce the loss of the medicine, the head of the connection rod 10 is provided in the form of a downwardly bent elbow on which the first spray head 21 is provided. The head of the connecting rod 10 adopts an elbow design, so that liquid flow can be complied, the resistance of the inner wall of the pipeline to liquid medicine is reduced, the impulsive force of the liquid medicine is dispersed, and the first spray head 21 at the end of the elbow occupies a part of the medicament space. The elbow is integrally formed with the connecting rod 10.

As shown in fig. 2, in a side view of the spraying device provided by the present invention, the angle between the elbow and the connecting rod 10 is β; the angle of β can be in the range of 125 ° -145 ° (i.e., 125 ° ≦ β ≦ 145 °), specifically, can be in the range of any one or two of 125 °, 127 °, 129 °, 131 °, 133 °, 135 °, 137 °, 139 °, 141 °, 143 °, and 145 °, for example, 125 ° ≦ β ≦ 130 °, 126 ° ≦ β ≦ 131 °, 127 ° ≦ β ≦ 132 °, 128 ° ≦ β ≦ 133 °, 129 ° ≦ β ≦ 134 °, 135 ° ≦ β ≦ 140 °, 136 ° ≦ β ≦ 141 °, 137 ° ≦ β ≦ 145 °. In actual use, a proper beta angle can be selected according to the growth characteristics of crops and artificial habits; for example, a larger β angle may be selected when the plant height is higher, whereas a smaller β angle may be selected when the plant height is lower.

The plurality of spray heads can atomize the medicament and are used for directly spraying the medicament on crops. When in actual use, a plurality of shower nozzles can be opened simultaneously, spun water smoke area is big, and because a plurality of (seven in figure 1) shower nozzles are not perpendicular to ground, but to the oblique side, the medicament can enter into the blade gap towards the oblique side to the spraying is to the blade back, has increased the spraying area to the blade, has improved the spraying efficiency of liquid medicine, and the manual work need not to wave the atomizer from top to bottom, has avoided the large tracts of land diffusion of medicine fog and is absorbed by the human body, has reduced the risk of people because of the medicament is poisoned.

By adopting the arrangement mode of the spray head, when in actual use, the spray space can be formed above or on the side of the plant leaves by fully utilizing the connecting rod 10, an important space frame effect is provided for the whole plant leaves in the spraying process, and the most basic connection effect is provided for the spray head and the handle; and because the above-mentioned mode that sets up of a plurality of shower nozzles for a plurality of shower nozzles can the synergism, complement each other, thereby make and also can dash and apply the blade back at the spraying of blade side, so that diversely spray, fully spray the liquid medicine to the plant, play good spraying effect.

The handle 30 is disposed at the bottom (lower part in fig. 1 and right end in fig. 2) of the connecting rod 10, and provides a grasping position for an operator to lift the whole spraying device, so as to operate the whole spraying device to spray. In order to reduce the occurrence that the spraying device slips from the hand due to the sliding of the handle 30 in the hand when an operator sprays medicine, and further wastes medicine liquid, even the situation that the medicine liquid is sprayed to a human body to cause human poisoning occurs, in a preferred specific embodiment, the handle 30 is provided with an anti-skidding device; the anti-slip means may be, for example, a protrusion provided on the handle 30, or an anti-slip material, such as rubber or silicone, sleeved on the handle 30. Furthermore, a ring of enclosure (not shown) may be disposed at the front end of the handle 30 (i.e. the end close to the spray head, in fig. 1, the upper portion of the handle 30, and in fig. 2, the left side of the handle 30), so as to reduce the liquid flow collected after the liquid medicine falls on the connecting rod 10 and/or the spray head 20, and the liquid flow of the liquid medicine flows onto the handle 30 along the connecting rod 10 during the operation and use process, thereby polluting the hands of the operator, and reducing the risk of the operator being poisoned by the liquid medicine.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
