Spraying device of partially flight

Abstract

The invention relates to a spraying device of partially flight, comprising an external expansion bracket, wherein slider A slidably connecting with the lower surface of a luggage rack and slider B slidably connecting with the upper surface of a link platform are respectively arranged at the upper and lower surface. And a fixed base is provided with the center of the upper surface of the link platform which is connected with a unidirectional screw through threads. The both sides of the unidirectional screw ratably relate to the lower surface of the external expansion bracket, and the lower surface of the link platform is connected with the upper surface of an internal expansion bracket through a rotary table. Four capes of the external expansion bracket are ratably connected with retractable external putters, wherein the bottom of two forward external puttershave walking wheels connected with and the bottom of two backward external putters have support units connected with. And four capes of the internal expansion bracketare ratably connected withretractable external putters, wherein the bottom of two forward internal putters have support units connected with and the bottom of two backward internal putters have walking wheels connected with. The spraying device of partially flight has the advantages of increasing the carrying weight of the drug and powerful terrain adaptability.

Description

Technical field [0001] The invention belongs to the technical field of agricultural equipment, in particular to a sprayer, in particular to a semi-flying sprayer. Background technique [0002] Today, as the world’s largest granary, China uses 10% of its arable land to feed 20% of its people. However, in terms of agricultural mechanization, there is a big gap with other countries. In most places, human farming is still used. This method greatly reduces the efficiency of agricultural production. In addition, nowadays, the rapid development of China, relying solely on agricultural income, is far from meeting people’s living expenses, and the output of food is greatly reduced. Therefore, there is an urgent need for a A mechanical device that can assist people to increase food production. Regarding crop spraying machinery, there are various spraying devices such as remote-controlled aircraft spraying, backpack-type foldable spraying machinery, etc. The remote-controlled aircraft spray...

[0002] Today, China, the world's largest granary, uses 10% of the arable land to feed 20% of the people. However, in terms of agricultural mechanization, there is a big gap with other countries. In most places, human farming is still used. way, greatly reducing the efficiency of agricultural production. In addition, in today's fast-growing China, only relying on agricultural income is far from meeting people's living expenses, and the output of food is also greatly reduced. Therefore, there is an urgent need for a A mechanical device that can assist people to increase food production. Regarding crop spraying machinery, there are various spraying devices such as remote-controlled aircraft spraying, backpack-type foldable spraying machinery, etc. The remote-controlled aircraft spraying device is carried by a remote-controlled aircraft. The spraying device is used for spraying. The knapsack foldable spraying machine is a spraying device that can be extended to a certain length through the drug arm carried by the tractor. Among them, the amount of medicine carried by the remote-controlled aircraft spraying device has a certain limit, and the cost is relatively high. High, the risk is high when working, and it is still difficult to popularize; the backpack-type foldable spraying machine needs to be carried by a tractor to work. Generally, fields with crops cannot enter, and the restrictions are relatively large. In order to prevent the center of gravity from shifting , the machines all work symmetrically and cannot be extended unilaterally; therefore, it is very necessary to provide a semi-flying sprayer with a large amount of medicine, strong terrain adaptability, a large spraying range, and unilaterally extended work.
