Knapsack directional spray device for fruit trees

Abstract

The invention discloses a knapsack directional spray device for fruit trees. The knapsack directional spray device is characterized in that two straps are respectively arranged at the left end and the right end of the front side of a tank, the lower portion of a pool extends into the tank, and the upper end of the pool is supported at the upper end of the tank; a feed inlet is formed in the top of the pool, and an electric fan is arranged on the top of the pool; a discharge outlet in the top of the pool is connected with one end of a spray hose, a spray nozzle is connected to the other end of the spray hose, and a discharge portion of the spray nozzle is in the shape of a flared opening; an ultrasonic atomization assembly is arranged in the tank and is positioned below the pool, and liquid in the pool can be atomized by the ultrasonic atomization assembly to obtain mist. The knapsack directional spray device has the advantages that the knapsack directional spray device can be accurately pointed to tree leaves or fruits which required to be sprayed, and is excellent in directional property, and normal growth of crops can be effectively guaranteed; the knapsack directional spray device is small in spray area, the mist cannot be easily blown away by contrary wind, and accordingly operators can be effectively prevented from being poisoned due to mist inhalation; the knapsack directional spray device is of a knapsack structure, the pool is small in capacity, and accordingly the knapsack directional spray device is portable and is applicable to spraying pesticides to orchards with small areas.

Description

technical field [0001] The invention belongs to the field of agriculture and forestry, in particular to a backpack-type fruit tree directional spraying device. Background technique [0002] In order to kill pests, fruit trees need to be sprayed. At present, a knapsack sprayer is generally used to spray pesticides. When spraying pesticides, the spray rod is used to point the leaves or fruits to spray pesticides. The defects of the existing methods are as follows: [0003] 1. In some cases, only the fruit needs to be sprayed, and in some cases, only the leaves need to be sprayed. However, the spraying range of the current sprayer is too large and the directionality is poor. This will affect the growth of fruit trees or the quality of fruits, etc., which is not conducive to agricultural production; [0004] 2. Due to the poor orientation and the large spraying area, if there is a headwind, the spray may blow to the operator, which may cause the operator to be poisoned. Cont...
