[0002] Containers are a common means of transportation in the modern logistics industry and are often used for bulk cargo transportation (grain, building materials and other bulk powdered or granular goods). At present, when containers are used for bulk grain transportation, the unloading method is mostly that the door opener first opens the two locking rods of the left door of the container, then opens the outermost locking rod of the right door, and finally faces the container door and swings the lock rod handle on the inside of the right door from bottom to top with an iron rod. After swinging, he immediately stops and runs away quickly. The door opens instantly due to the outward expansion force of the bulk grain. Due to the impact force of the bulk grain on the door, the door pops out vigorously. If the operator is not careful, it will injure the door opener or the bulk grain will directly pour onto the door opener, causing personal injury. Therefore, it is urgent to propose a safe door opening device for bulk grain containers to solve the above technical problems. Utility Model Content

[0017] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0018] The terms "disposed", "connected" and "fixed" should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Example: See Figure 1-Figure 3 , a bulk grain container safety door opening device of this embodiment includes a switch type magnetic seat 1, a cylinder 2, a connecting bracket 3, a bolt 4, an air pipe 5 and a foot-operated pneumatic switch 6;

[0022] The connecting bracket 3 is an inverted L-shaped bracket, with holes processed on its horizontal plate and threaded holes processed on its vertical plate;

[0023] The cylinder 2 is arranged on the switch type magnetic base 1, and the cylinder rod of the cylinder 2 passes through the through hole of the L-shaped bracket, and the L-shaped bracket is connected to the switch type magnetic base 1 through a bolt 4;

[0024] The air inlet and outlet of the air cylinder 2 are connected to the foot-operated pneumatic switch 6 through the air pipe 5;
