Description

Technical Field

[0001] This utility model relates to the field of feed pellet mill technology, specifically to a reinforced hexagonal door for a feed pellet mill. Background Technology

[0002] Pellet mills are widely used in feed production. Currently, pellet mill doors are available in round and hexagonal shapes (actually octagonal, but referred to as hexagonal doors in the industry due to the feeding port design). Pellet mill doors are exposed to high temperatures and vibrations for extended periods. Due to the inherent structure of hexagonal doors, they are prone to deformation, resulting in incomplete sealing of the pelleting chamber. The hinges of pellet mill doors currently use a sliding friction fit between a pin and a steel sleeve. Some products have a copper sleeve inside the steel sleeve, and copper washers are used for axial positioning. After a period of use, the copper sleeve, pin, and copper washer will all wear down. The deformation of the door body at the hinge and the wear of the pin and steel sleeve will cause severe deformation on the other side of the hexagonal door, leading to significant door displacement and interference with the fixed door. Therefore, there is room for improvement. Utility Model Content

[0003] The purpose of this invention is to provide a reinforced hexagonal door for a feed pellet mill to solve the problems mentioned in the background art.

[0004] A reinforced hexagonal door for a feed pellet mill includes a housing with a door panel on one side. The housing and door panel are connected by a connecting mechanism, which includes a fixing plate fixed to one side of the housing. A mounting plate is fixedly connected to the outer wall of the fixing plate. A hexagonal door upper hinge pin and a hexagonal door lower hinge pin are respectively located at the top and bottom of one side of the mounting plate. The mounting plate is connected to the door panel via the hexagonal door upper and lower hinge pins. The upper hinge pin houses a thrust ball bearing and a cylindrical roller bearing, while the lower hinge pin houses a spherical bearing.

[0005] By adopting the above technical solution, the upper hinge pin of the door hinge uses a combination of cylindrical roller bearings and thrust ball bearings to ensure high-position rotation of the door hinge; while the lower hinge pin uses a spherical bearing, which can meet the requirements of the bearing combination for the coaxiality of the upper and lower bushings of the door body and the upper and lower bushings of the housing. By using the bearing combination, the sliding friction at the hinge is improved to rolling friction, making the opening and closing of the door easier; and eliminating the door displacement caused by the deformation of the door itself and the wear of the hinge shaft and bushing.

[0006] The present invention is further configured such that the fixing plate is connected to the housing by bolts, and the fixing plate is connected to the mounting plate by bolts.

[0007] By adopting the above technical solution, the bolt connection method facilitates the installation and disassembly of the fixing plate, improving the ease of operation.

[0008] The present invention is further configured such that the fixing plate and the mounting plate are installed and fixed in a relatively aligned manner.

[0009] By adopting the above technical solution, when the fixing plate and the mounting plate are installed and fixed in alignment, the contact area between the fixing plate and the mounting plate can be increased, thereby improving the stability of the installation.

[0010] The present invention is further provided that both the upper hinge pin and the lower hinge pin of the hexagonal door are provided with lubricating oil.

[0011] By adopting the above technical solution and the setting of lubricating oil, the friction of the bearing can be reduced, further improving the ease of use of the hexagonal door switch.

[0012] The present invention is further configured such that the inner wall of the door panel is provided with three reinforcing plates, which are distributed in the inner frame of the door panel.

[0013] By adopting the above technical solution and adding reinforcing plates, the thickness and rigidity of the door panel can be increased, preventing deformation of the door panel under high temperature and vibration environments. The present invention is further configured such that the reinforcing plate is made of carbon steel.

[0014] By adopting the above technical solution, the carbon steel reinforcing plate has better strength, further improving the protection of the door panel. Compared with the prior art, the beneficial effects of this utility model are: the feed pellet mill has a reinforced hexagonal door, In use, the upper hinge pin of the door hinge uses a combination of cylindrical roller bearings and thrust ball bearings to ensure high-position rotation of the door hinge; while the lower hinge pin uses spherical plain bearings, which can meet the requirements of the bearing combination for the coaxiality of the upper and lower bushings of the door body and the upper and lower bushings of the housing. By using the bearing combination, the sliding friction at the hinge is improved to rolling friction, making the opening and closing of the door easier; and eliminating the door displacement caused by the deformation of the door itself and the wear of the hinge shaft and bushing.
