Description

A New Mechanical Orchard Sprayer

technical field

The utility model relates to an orchard sprayer, in particular to a novel mechanical orchard sprayer with mechanical power and large-area spraying.

Background technique

With the development of China's economy and the adjustment of the agricultural industrial structure, the orchard planting area has become larger and larger, and has become an important pillar of the rural economy and the main source of farmers' income. , Pests and diseases occur frequently without effective control, resulting in fruit drop, secondary fruit and inferior fruit. The present situation that China's plant protection machinery and pesticide use technology is seriously backward is extremely disproportionate to China's orchard planting. Negative effects such as drug injury and operator poisoning have caused undue losses and other adverse consequences. Pesticide application technology is a problem that has not been paid attention to in China so far, but actually has a great impact on the control of agricultural diseases and insect pests. Pesticides, medical equipment, and pesticide application technology are three equally important links in the scientific and rational use of pesticides. At present, most orchards in China adopt the low and dense planting mode, the row spacing is 4-5m, the plant spacing is 3-4m, the tree height is 3-3.5m, the crown thickness is about 3.5m, and the stem height is relatively short, with an average stem height of 0.3-0.5. m, because the crown thickness is close to the row spacing, the branches and leaves of two rows of fruit trees are almost handed over, resulting in a closed orchard, which is not conducive to the management of the orchard ground, it is difficult for agricultural machinery to enter the field, and the difficulty of pest control and labor intensity increase. Most of the domestic use of hydraulic atomization technology, due to the tall fruit tree canopy, dense branches and leaves, it is difficult for the pure hydraulic atomization mist to penetrate the fruit tree canopy and deposit evenly, and often the mist is blocked by the outer dense leaf curtain and gathers to form water droplets Rolling and loss will cause the pests and diseases inside the canopy and the trunk to not be effectively controlled, and increase the number of spraying, resulting in a large amount of waste of pesticides and serious environmental pollution. While causing a large amount of waste of pesticides, it is also an important reason for inducing pest resistance. one. For orchards with poor conditions, manual pesticide application is still the main method. The main varieties are manual sprayers and pedal sprayers. Their work efficiency is low, and they cannot be properly controlled. It is difficult to spray pesticides in place or spray unevenly, and the pesticides cannot fully play their role Simultaneously, it consumes a lot of man-hours, the labor intensity of the operators is large, and the conditions are poor, and the orchard growers manually apply pesticides in a sultry, airtight, humid orchard environment, which is prone to poisoning incidents. Therefore, it is imminent to improve the level of China's pesticide application technology by developing and applying advanced plant protection machinery, strengthening the research on pesticide application technology and methods, and vigorously promoting correct and efficient pesticide application methods.

In this structure, the user can realize remote control of the spray angle of the spray rod and spray head through the motor controller, such as through the control of personnel operating other power machinery, which can not only realize flexible control, but also realize automatic control. The efficiency has been greatly improved; at the same time, through the remote control of the clutch, the clutch can be connected when spraying is required, and the clutch can be quickly separated when spraying is not required, reducing the load of other power machinery and saving energy. Turning on and off other power machinery can reduce the number of switches, indirectly save energy and improve efficiency.

Specifically, the clutch is a manual clutch, and its control input end is connected to the clutch controller through a mechanical connection section; or, the clutch is an automatic clutch, and its control input end is connected to the clutch controller through a wire. The specific clutch structure can adopt a conventional clutch structure as required.

The beneficial effects of the utility model are:
