Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a fully sealed explosive conveying mechanism. Background Technology

[0002] Explosives conveying lines have high requirements, especially for sealing and dust (powder) handling. Powder falling into the rotating shaft motor can easily cause an explosion. At the same time, there must be no electrostatic sparks (metal-to-metal contact). When traditional cylinders are lifting, static electricity is easily generated at the guide sleeve and guide rod. If a large amount of powder falls in, it can easily generate sparks, which can lead to an explosion in severe cases. In addition, deposits can easily accumulate at the bearings of the conveying rollers, affecting safe production. Summary of the Invention

[0003] The purpose of this utility model is to provide a fully sealed explosive conveying mechanism with reasonable structure and good performance.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: a fully sealed explosive conveying mechanism, comprising a conveying roller, a roller frame, support legs, and a stopper. The roller frame consists of two sets, with a greater than number of conveying rollers installed between the two sets of roller frames. Support legs are installed at the bottom of the roller frame, and a shell is fastened to the roller frame. The shell has a C-shaped vertical cross-section, with its open end facing the conveying roller. An air port is provided on the bottom of the shell at the open end, and a baffle is installed between the two sets of roller frames in the output direction. A cylinder is installed on the baffle, and the piston rod of the cylinder is connected upward to a guide rod. A stopper is installed on the top of the guide rod, and a bellows cover is provided on the outside of the stopper.

[0005] A guide sleeve is installed on the top of the baffle, and a cylinder is installed at the bottom of the baffle. The piston rod of the cylinder passes upward through the baffle and the guide sleeve and is connected to the guide rod.

[0006] The bellows cover is a cylindrical shape made of coated cloth, with its top connected to the upper part of the guide rod to form a seal, and its lower part connected to the guide sleeve to form a seal.

[0007] The conveyor roller is equipped with a drive shaft at its end. The drive shaft is mounted on the roller frame through a corresponding bearing seat and is driven by a corresponding hydraulic motor.

[0008] The top of the stopper is equipped with a bearing, and the bearing shaft is horizontal.

[0009] Compared to traditional conveyors, this invention features a unique outer shell made of aluminum plate, offering excellent corrosion and weather resistance. An air inlet is continuously pressurized to prevent powder accumulation. Sealing rings are installed at all connections to minimize dust entry into the mechanism. A cylinder drives a guide rod to rise, causing a stopper to rise and block the product. A nylon bellows cover is installed on the outside of the stopper to prevent dust from falling. Horizontally mounted bearings prevent the stopper from jamming during extension / retraction. This design results in a reasonable structure and excellent performance. Attached Figure Description

[0014] The present invention will be further described below with reference to all the accompanying drawings. The preferred embodiment of the present invention is as follows:

[0015] The embodiments described in this paper with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0016] In the description of this patent, it should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0017] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0018] The fully sealed explosive conveying mechanism described in this embodiment includes a conveying roller 1, a roller frame 2, support legs 11, and a stopper 9. The roller frame 2 consists of two sets, with more than two conveying rollers 1 installed between the two sets. Support legs 11 are installed at the bottom of the roller frame 2. A housing 4 is fastened to the roller frame 2, with a C-shaped vertical cross-section. Its open end faces the conveying roller 1. A through-hole vent 5 is provided on the bottom of the housing 4 at the open end. A baffle 6 is installed between the two sets of roller frames 2 in the output direction. A cylinder 8 is installed on the baffle 6, with its piston rod connected upwards to a guide rod. A stopper 9 is installed on the top of the guide rod, and a bellows cover 10 is provided on the outside of the stopper 9. A guide sleeve 7 is installed on the top of the baffle 6, and the cylinder 8 is installed at the bottom of the baffle 6.
