Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
The utility model provides a fan that is used for adjustable amount of wind on maize picker, includes the fan body, and the fan body adopts the two air intake fans that adopt on the current maize picker.
An air quantity adjusting plate is arranged on the air inlet at one side of the fan body or an air quantity adjusting plate 3 is respectively arranged on the air inlets at two sides of the fan body. The air volume adjusting plate is an arc-shaped bent plate, a hinge hole is formed in one end of the arc-shaped bent plate, and a hinge shaft or a bolt 4 penetrates through the hinge hole, so that the end of the arc-shaped bent plate is hinged with the end part of the fan shell barrel 1. The other end of the arc-shaped bent plate is provided with an arc-shaped connecting long hole 3-1, the arc-shaped connecting long hole is arranged by taking the hinged position as the center, the A end of the arc-shaped connecting long hole is one end far away from the hinged connection, and the B end of the arc-shaped connecting long hole is one end close to the hinged connection; a locking screw 2 connected with the end part of the fan shell is arranged in the arc-shaped connecting long hole in a penetrating way, so that the whole air quantity adjusting plate is fixed at the air inlet of the fan in an adjustable way.
The air quantity adjusting plate is adjusted to the contact position of the end A of the arc-shaped connecting long hole and the locking screw, and referring to the position of fig. 1, the whole air quantity adjusting plate is positioned at the external position which is completely staggered with the air inlet, so that the air quantity adjusting plate is ensured to be consistent with the original air quantity when the air quantity adjusting is not needed. The air quantity adjusting plate is adjusted to the contact position of the end B of the arc-shaped connecting long hole and the locking screw, the whole air quantity adjusting plate is located at the maximum covering position of the air inlet, and the minimum air inlet quantity and the minimum air outlet quantity can be realized at the position.
In the above case, the air volume adjusting plates are preferably symmetrically arranged on both sides of the air inlet. Has the advantages that: 1. the air quantity adjusting plates with the same structures are arranged on the two sides, so that the air quantity adjusting plates are convenient to manufacture, manage and use; 2. the symmetrical installation can make the intake of the two sides of the fan change equivalently, make the intake uniform, ensure the normal operation of the functional parts and prolong the service life of the fan.
