Description

Technical Field

[0001] This utility model relates to the field of combustion engine technology, specifically to a duct device for a biomass pellet burner. Background Technology

[0002] A biomass pellet burner is a machine that generates heat by burning biomass pellets obtained through a special process. In order to ensure the continuity of feeding and the uniformity of combustion, most biomass pellet burners are equipped with air duct devices.

[0003] The existing air duct device of the biomass pellet burner supplies air to the combustion chamber during use, which only serves to aid combustion. This makes it impossible for the air duct device to adjust the air volume according to the personnel's requirements, resulting in limitations in the equipment's combustion support. At the same time, the air duct opening cannot be protected when not in use, allowing unknown organisms to enter the inner wall of the equipment and damage the inner wall components. Utility Model Content

[0007] As a preferred technical solution of this utility model: the outer wall of the connecting rod is semi-arc, the semi-arc plate and the folding plate are spliced ​​together, and the outer walls of the semi-arc plate and the folding plate are adapted to the inner wall of the square plate.

[0008] As a preferred technical solution of this utility model: the controller and the second motor are electrically connected, and the outer wall of the gear meshes with the outer wall of the gear plate.

[0009] As a preferred technical solution of this utility model: the inner wall of the toothed plate is rotatably connected to the outer wall of the adjusting plate, and there are two limiting blocks, which are symmetrically arranged with the toothed plate as the center.

[0010] As a preferred technical solution of this utility model: the number of support rods is four, and the four support rods are evenly distributed at the four corners of the outer wall of the square plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The air duct device of this biomass pellet burner uses a second motor to drive the gear to rotate via a control controller. The outer wall of the gear meshes with the outer wall of the toothed plate, causing the gear to drive the toothed plate to rotate on the inner wall of the air duct to adjust the air volume. The inner wall of the toothed plate forms a rotational connection with the outer wall of the adjustment plate, causing the toothed plate to drive two limit blocks to rotate on the outer wall of the adjustment plate to achieve misalignment. Thus, the air volume can be stably adjusted according to personnel requirements.

[0013] 2. The air duct device of this biomass pellet burner, through the control controller, uses a first motor to drive the folding plate to rotate. The folding plate drives the semi-arc plate to rotate through the connecting rod, so that the semi-arc plate drives the long rod to rotate on the inner wall of the square plate. The outer wall of the connecting rod is semi-arc. The folding plate drives the semi-arc plate to rotate on the inner wall of the square plate through the connecting rod to fold and fold, thus shielding and protecting the inner wall of the square plate. When not in use, the first motor drives the folding plate to rotate in the opposite direction. The folding plate drives the connecting rod to pull the semi-arc plate, so that the folding plate and the semi-arc plate are in a parallel state, and the inner wall of the square plate is opened.
