Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example 1: in order to effectively avoid the problem that the grain is easy to impact workers due to the fact that the grain is dumped in the process of opening the door and discharging the grain in the process of grain container transportation, and the degree of mechanization and automation of the grain container transportation is further improved. The utility model provides an automatic opening and closing door device of container as shown in figure 1, comprising a first support 1, a second support 2, an oil cylinder 3, a special-shaped connecting rod 4 and a roller 5, wherein the first support 1 is arranged on the side wall of the container door by using fixing parts such as bolts, the second support 2 adopts the same mounting method, and the first support 1 and the second support 2 are arranged on the same horizontal line,

the second support 2 is closer to a door post of a container door when being installed, the first support 1 is installed at a suitable position far away from the door post, and the first support 1 is higher than the second support 2, so that the oil cylinder 3 in subsequent installation is prevented from being influenced by the second support 2.

The three-section connecting rod with a shape like a Chinese character 'ji' of the special-shaped connecting rod 4 shown in fig. 3 comprises a first end point 41, a second end point 42, a third end point 43 and a fourth end point 44, wherein the top of the second support 2 is provided with a shaft hole, the first end point 41 of the special-shaped connecting rod is installed by using a rotating shaft, the cylinder body end of the oil cylinder 3 is installed on the first support 1 by the same method, the rod end of the oil cylinder 3 is installed at the second end point 42 of the special-shaped connecting rod by using a rotating shaft, and the fourth end point 44 of the special-shaped connecting rod is installed with a roller 5 by using a rotating shaft.

When the oil cylinder 3 extends out as shown in fig. 4, the fourth end point 44 of the special-shaped connecting rod 4 is pressed downwards towards the door of the container under the action of the lever principle, so that the roller 5 is pressed against the door of the container, and the door of the container is pressed and closed; when the oil cylinder 3 retracts, the fourth end point 44 tilts to loosen the door of the container, the door which loses pressure is opened, and grains and the like in the container can be poured out.

In the implementation process, the container door and the automatic container door opening and closing device are in a separated state, and in the retraction process of the oil cylinder 3, the end part of the opening and closing device leaves the container door and is not actively applied to the container door, so that the container door can not be automatically opened. In order to avoid the situation, a retaining ring is arranged on the third end point 43 of the special-shaped connecting rod, the retaining ring is connected with the inhaul cable 6, the other end of the inhaul cable 6 is connected to the position, far away from the door post, of the container door, and when the special-shaped connecting rod 4 is lifted up, the inhaul cable 6 pulls the container door to open the container.

Each connecting position of the automatic door opening and closing device of the container needs frequent rotation, and under the premise of further improving the rotation reliability, the utility model discloses the people improves the overall reliability of the device at each connecting position installation connecting pieces such as bearings. Meanwhile, in order to prevent the device from generating an influence with other devices on the door, the automatic door opening and closing device of the container is preferably arranged at the position of the upper door frame which has small influence on the door of the container.

Example 2: the special-shaped connecting rod 4 only has a first end point 41 and a second end point 42 which are connected with stress points, and a third end point 43 and a fourth end point 44 which are longer parts of the special-shaped connecting rod are in a suspended and unsupported state, and the parts can bend downwards under the action of gravity after long-time use. In order to avoid such a problem, as shown in fig. 4, a slide 71 for sliding the roller 5 is mounted on the box door by using a bolt, as shown in fig. 5, the slide 71 is mounted in a state of being mounted, a rectangular plate is symmetrically mounted in the left and right, a groove for sliding the roller is formed in the middle of the rectangular plate, the roller 5 moves in the slide 71, and the slide 71 can play a role of supporting. On this basis utility model people set up spout 72 on slide 71, and the pivot of installing gyro wheel 5 is through the extension, makes the tip of pivot can stretch into in the spout 72, and in this kind of structure, when special-shaped connecting rod 4 lifted, the pivot can be supported on the border of spout 72, provides the pulling force for the chamber door, opens the chamber door. In this embodiment the cable 6 can be installed as a security component or can be removed to save some costs.

Example 3: on the basis of the foregoing embodiment, the oil cylinder 3 can be operated by increasing the length of the oil pipe using the hydraulic system of the transportation vehicle. The container is placed on different transport vehicles, an oil pipeline of the oil cylinder is connected with the transport vehicles, and when a door of the container needs to be opened, a driver only needs to operate a vehicle hydraulic system in a vehicle cab to complete opening and closing of the door. Further optimization can link the oil cylinder 3 with a vehicle system, and automation of the automatic door opening and closing device of the container is realized.
