Pollination device for pear tree planting

Abstract

The invention discloses a pollination device for pear tree planting, and relates to the technical field of pollination devices. The pollination device comprises a handheld supporting pipe, a micro high-pressure tank, a pollination box and a spraying device, wherein the spraying device comprises a conveying main pipe; and the tail end of the conveying main pipe is provided with first spraying headsin a communicating mode, the top end of the conveying main pipe communicates with the handheld supporting pipe in a connecting mode, and an annular spraying structure is arranged on the conveying main pipe in a sliding mode. According to the pollination device for pear tree planting, the handheld supporting pipe communicates with the conveying main pipe, meanwhile, the micro high-pressure tank isarranged on the handheld supporting pipe, the pollination box is arranged on the conveying main pipe, and a plurality of second spraying heads of the spraying device are annularly and uniformly distributed on the circumferential sides of the first spraying heads; and during use, a first electromagnetic valve and a second electromagnetic valve are opened, and pollen in the pollination box passes through the conveying main pipe, a hose and an arc-shaped conveying pipe and is sprayed to stigmas in pistils through the first spraying heads or the second spraying heads through high-pressure gas, sothat uniform and efficient pollination and uniform spraying of clustered pear flowers are achieved, and the pear flower pollination efficiency and the pear flower pollination effect are improved.

Description

technical field [0001] The invention belongs to the technical field of pollination devices, in particular to a pollination device for planting pear trees. Background technique [0002] In the process of pear tree planting, in order to improve the fruiting rate of pear trees, it is often necessary to artificially pollinate pear flowers during the pollination period of pear trees. Existing pear flower pollination often adopts a fluffy device with adhered pollen, dips the pollen from the pollen box, and shakes the fluffy device adhered to the pollen in the middle of the pistil of the pear flower, so that the fluffy device sticks The attached pollen falls on the stigma of pear flowers to increase the fruit setting rate of pear flowers. This method is often used for artificial pollination. Although this method is good, it needs to manually pollinate each pear flower, and the efficiency is relatively slow. And this way, can not guarantee that every section of flower in the clust...

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of pollination device that is used for pear planting, communicates with conveying main pipe through hand-held support pipe, installs miniature high-pressure tank on the hand-held supporting pipe simultaneously, installs pollination box on the conveying main pipe; The nozzles are evenly distributed around the first nozzle; when in use, the first solenoid valve and the second solenoid valve are opened, and the high-pressure gas transports the pollen in the pollination box through the main pipe, hose and arc-shaped conveying pipe to the first nozzle or the second nozzle. The second nozzle is sprayed on the stigma in the stamen, which solves the problem of low efficiency and poor pollination effect of the existing artificial pollination
