Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material guiding chutes, in particular to a material guiding spoon used for a material guiding chute. Background Art
[0002] In the fields of thermal power, coal chemical industry, steel and coal mine, bulk materials need to be transported. Generally, a guide chute is set at one end of the main belt conveyor. Several discharge ports can be set at the lower end of the guide chute. A secondary belt conveyor is set below the discharge port. Since the materials on the main belt conveyor fall forward and downward at a certain speed and trajectory, if they fall directly on the back plate of the head hopper on the guide chute, it will cause a strong impact on the back plate of the head hopper, causing serious wear and generating a large amount of dust. Therefore, it is necessary to set a guide spoon in the head hopper to reduce the impact, reduce wear and reduce the generation of dust. The guide spoon of the prior art has a structure as shown in the application number 201520428414.4 and is named a belt conveyor head guide spoon device (only the main belt conveyor is drawn). The machine comprises a head guard, a head hopper and a material guide spoon. In fact, an electric tee is arranged below the head hopper. The outlet of the electric tee is connected to the curved chute. The lower end of the curved chute is the outlet. The head guard, the head hopper, the material guide spoon, the electric tee and the curved chute constitute the material guide chute). A horizontal rotating spindle is arranged on the back of the material guide spoon baffle. The top of the screw rod on the vibration adjustment device is connected to the lower part of the material guide spoon baffle through a hinge seat. The inclination angle of the material guide spoon baffle can be adjusted by turning the hand wheel, so that the material flow and the material guide spoon plate body have a better fit. However, after the adjustment is completed, the lower end of the material guide spoon baffle will produce a vertical displacement, which will cause an upward or downward force on the end of the screw rod, forming a torque. When the torque is large, the screw rod or the head guard can be deformed. Utility Model Content

[0014] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0015] Specific implementation method: Combination Figure 1-3As shown, a material guide spoon for a material guide chute comprises a spoon body 1. The structure of the spoon body 1 is the same as that of the material guide spoon baffle in the background technology, and has an arc structure and a U-shaped cross section. A horizontal rotating shaft 4 is arranged on the back of the spoon body 1. The two ends of the rotating shaft 4 are used to connect with the mounting seats arranged on both sides of the head funnel. Two tail plates 6 are arranged at the lower part of the back of the spoon body 1. A pin shaft 7 is arranged between the two tail plates 6. The extension direction of the pin shaft 7 is parallel to the extension direction of the rotating shaft 4. A push-pull plate 5 is also included. The push-pull plate 5 includes a plate body 51. The plate body 51 is perpendicular to the pin shaft 7, and is provided with a long hole 511 extending in the vertical direction. The plate body 51 is located between the two tail plates 6 and the pin shaft 7 is located in the long hole 511. The end of the plate body 51 away from the spoon body 1 is provided with a connecting head 52 for rotationally connecting to the screw rod on the vibration adjustment device. The thickness of the plate body 51 is slightly smaller than the distance between the two tail plates 6, and the diameter of the pin shaft 7 is slightly smaller than the width of the long hole 511, so that the tail plate 6 can slide relative to the plate body 51, and the plate body 51 basically does not rotate when the screw rod is rotated. When adjusting the inclination of the spoon body 1, rotating the screw rod will cause the spoon body 1 to rotate a certain angle around the rotating shaft 4. During this process, the pin shaft 7 will move up and down along the long hole 511. Since the extension direction of the long hole 511 is the vertical direction, the pin shaft 7 basically does not generate a vertical force on the long hole 511 (the vertical force generated by the spoon body 1 acts on the rotating shaft 4 and is borne by the rotating shaft 4), so the screw rod is basically not subjected to torque.
[0016] Preferably, the back of the spoon body 1 is provided with a plurality of longitudinal ribs 3 for reinforcement. The rotating shaft 4 passes through the plurality of longitudinal ribs 3 in a transverse direction.
[0017] Preferably, a plurality of transverse ribs 2 are provided on the back of the spoon body 1 for reinforcement.
[0018] Preferably, the pin shaft 7 is rotatably connected to the tail plate 6 , so the friction force generated between the pin shaft 7 and the long hole 511 is very small, and it is difficult to generate a vertical force on the long hole 511 .
[0019] The above embodiments are merely descriptions of preferred implementation schemes of the present invention, and are not intended to limit the protection scope of the present invention. Without departing from the design spirit of the present invention, any modification and improvement of the technical solution of the present invention made by a person of ordinary skill in the art shall fall within the protection scope of the present invention.
