[0001] The utility model relates to a novel integral hopper unloading door device, belongs to the technical field of material storage and batching, and is used for unloading a granular material hopper. Background Art
[0002] For hoppers with larger sand and gravel particles, since the particles of the materials are larger, general discharge doors such as butterfly valves and gate valves are difficult to adapt to, so special discharge doors are needed to meet their discharge needs. There are relatively few types of discharge doors on the market, which are difficult to meet the discharge needs of hoppers of different types and specifications. In addition, traditional sand and gravel hoppers usually use U-shaped side swing doors driven by cylinders, which are essentially welded together with the hopper, cannot be disassembled, and are not interchangeable, which brings inconvenience to maintenance and replacement.
[0003] In actual use, the welding structure is prone to problems such as non-concentricity of the door shafts on both sides, difficulty in opening and closing the door, and uneven gaps. These problems not only affect the unloading efficiency and quality of the hopper, but also cause unnecessary safety hazards during use. Therefore, a new design is needed to solve these problems.

[0005] A novel integral hopper unloading door device comprises a hopper, a feeding port is arranged at the bottom of the hopper, two panels arranged parallel to each other are installed on the hopper near the feeding port, a panel sleeve is embedded on the outer side of each panel, a first pin shaft hole is radially arranged on each panel sleeve, a self-lubricating unit is installed on the panel sleeve, a door body is installed on the hopper for rotation through a door body hinge shaft, and the door body is driven by an opening and closing unit to open and close the feeding port.
[0006] The opening and closing unit includes a cantilever, a cylinder articulated seat, a cylinder, a front articulated shaft and a rear articulated shaft. A cantilever arranged in a horizontal direction is welded on the hopper on one side of the discharge port. The cantilever is arranged in a horizontal direction. The cylinder articulated seat is installed on the end of the cantilever away from the hopper. The cylinder body of the cylinder is hinged on the cylinder articulated seat through the rear articulated shaft, and the piston rod of the cylinder is hinged on the door body through the front articulated shaft.
[0007] The self-lubricating unit includes a door body sleeve, an open-end conical pin and an oil nozzle. The door body sleeve is installed on both sides of the door body. An oil groove is arranged on the door body sleeve. A second pin shaft hole and a lubricating oil channel are arranged on the door body hinge shaft.

An oil nozzle is installed at one end of the lubricating oil channel, and the other end is connected to the oil groove. When the door body hinge shaft passes through the panel sleeve and the door body sleeve, the open-end conical pin passes through the first pin shaft hole and the second pin shaft hole.
[0008] Nylon adjustment pads are also arranged on both sides of the door body shaft sleeve.
[0009] The advantages of the utility model are: it integrates the discharge port, door body, cylinder and other parts, and it is easy to ensure the coaxiality of the door shafts on both sides and the door body gap through tooling welding, which can effectively avoid the problems of unloading door jamming and difficulty in opening and closing the door, and the switch position is accurate; in addition, the new integrated unloading door device can be completely separated from the hopper, which greatly reduces the processing and manufacturing cost and difficulty, greatly improves the versatility and interchangeability of the unloading door device, and facilitates mass production.

However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements fall within the scope of protection of the present invention.
[0022] See also Figures 1 to 11 The utility model relates to a novel integral hopper discharge door device, including a hopper 1, a discharge port 2 is arranged at the bottom of the hopper 1, two panels 9 arranged parallel to each other are installed on the hopper 1 close to the discharge port 2, a panel sleeve 10 is embedded on the outer side of each of the panels 9, a first pin shaft hole 12 is radially arranged on each of the panel sleeves 10, a self-lubricating unit is installed on the panel sleeve 10, a door body 4 is installed on the hopper 1 to rotate through a door body hinge shaft 3, and the door body 4 is driven by an opening and closing unit to open and close the discharge port 2.
[0023] The design of setting the discharge port at the bottom of the hopper can more accurately control the discharge flow and speed, and improve the discharge efficiency and quality. The self-lubricating unit is used to automatically lubricate the panel sleeve, which can save the time and cost of manually adding lubricating oil, greatly reduce the maintenance difficulty of the equipment, and extend the service life; the design of two panels set parallel to each other reduces the possibility of door body instability and improves the accuracy and stability during use. The opening and closing unit is used to drive the door body, which can more easily and conveniently control the opening and closing of the door body, improving the convenience and efficiency of operation.
[0024] The opening and closing unit includes a cantilever 11, a cylinder articulated seat 8, a cylinder 6, a front articulated shaft 5 and a rear articulated shaft 7. A cantilever 11 arranged in a horizontal direction is welded on the hopper 1 on one side of the discharge port 2. The cantilever 11 is arranged in a horizontal direction. The cylinder articulated seat 8 is installed on the end of the cantilever 11 away from the hopper. The cylinder body of the cylinder 6 is articulated on the cylinder articulated seat 8 through the rear articulated shaft 7, and the piston rod of the cylinder 6 is articulated on the door body 4 through the front articulated shaft 5.
[0025] Firstly, the cylinder articulated seat 8 and the cylinder 6 are installed on the cantilever, so as to reduce the height of the door body, thereby reducing the center of gravity and increasing stability and safety.

[0030] The operator drives the cylinder to make the piston rod open and close the door body through the front hinge shaft, thereby controlling the opening and closing degree of the discharge port.
[0031] At the connection of the door body hinge shaft, the first pin shaft hole and the second pin shaft hole are connected through the open-end conical pin, and the door body hinge is automatically lubricated through the self-lubricating unit of the door body sleeve, oil groove and lubricating oil channel to maintain the flexibility and stability of the door body.
[0032] In addition, the panel bushing enables the door body to rotate smoothly inside the panel bushing. At the same time, the self-lubricating unit installed on the panel bushing also provides lubrication for this part, further improving the reliability and service life of the door body.
[0033] In summary, the design of the unloading door device fully considers the reliability of the equipment and the comfort of operation. At the same time, it adopts an automatic lubrication unit to provide a guarantee for reducing maintenance costs and improving maintenance efficiency, and can meet the unloading needs of industrial production.
