Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural machinery technical field, concretely relates to a cotton picker bottom shield opening and closing device. BACKGROUND

[0002] Cotton planting is widespread in China. In the past, cotton harvesting mainly relied on manual picking, which not only had extremely high labor intensity, but also was low in efficiency. However, with the continuous advancement of agricultural mechanization, the application of cotton picker becomes more and more common. The use of cotton picker greatly improves the picking speed, effectively reduces the labor burden, and significantly improves the economic benefit. The cotton picker has a smooth metal plate shield at the bottom of the chassis, which is usually referred to as the bottom shield. These bottom shields close the engine compartment to prevent burrs, green cotton bolls, cotton sticks and other debris from entering, and also allow workers to conveniently inspect and maintain.

[0003] The existing cotton picker with publication number CN221032827U is a full-package protective cover, which includes a cylindrical protective cover combined by a first protective cover and a second protective cover. The first protective cover and the second protective cover are both semi-cylindrical. The first protective cover is provided with a plurality of first holes, and the first protective cover and / or the second protective cover is provided with a plurality of supports. An end protective cover is provided at one end of the cylindrical protective cover. A third protective cover extends axially and is provided on the outer wall of the second protective cover. The third protective cover is provided with a plurality of third holes and a rectangular hole. A fourth protective cover is provided on the outer wall of the third protective cover and is used to shield the rectangular hole. The fourth protective cover is provided with a fourth hole. The utility model integrates multiple protective cover components and designs different structures and sizes of holes on each protective cover, which has compact overall structure design, reduces part cost, occupies small space, and effectively reduces heat conduction and heat radiation of post-processing.

[0004] Each shield door has an independent opening and closing device, and the shield door needs to be opened and closed multiple times during maintenance and inspection. This results in the existing cotton picker bottom shield opening and closing device having the problems of low work efficiency, low production efficiency, and high production cost. Therefore, it is necessary to design a cotton picker bottom shield opening and closing device to solve the above problems. UTILITY MODEL CONTENTS

[0005] The present scheme provides a cotton picker bottom shield opening and closing device to solve the problem of not being able to open multiple doors at once.

[0006] The present scheme provides a cotton picker bottom shield opening and closing device, which includes a rack.

[0007] First door: the first door is rotatably connected to the rack.
