[0011] According to the coal conveyor buffer plate, the elastic mounting frame is an L-shaped plate with the top corner facing the rear. The upper end is fixed to the baffle frame, and the lower end has an opening through which the guide rod passes. In the initial stage, the lower part of the L-shaped plate is parallel to the baffle frame.

[0012] According to the coal conveyor buffer baffle, the baffle frame is a vertical frame structure with an ear plate protruding from the top towards the conveyor side. The same ear plate holes are provided on the upper and lower rear parts of the metal base plate.

[0023] The specific details of this utility model are further described below:

[0024] This utility model relates to a coal conveyor buffer baffle, comprising a metal base plate 1, a belt baffle 2, and a baffle frame 3. The top of the metal base plate 1 is hinged to the baffle frame 3, which is fixed to the conveyor frame. The belt baffle 2 is fixed to the inner side of the metal base plate 1 on the conveyor side. An elastic support is provided on the lower rear side of the metal base plate, with its rear end connected to the lower part of the baffle frame 3. This device is installed on both sides of the coal conveyor. The elastic support at the rear of the metal baffle and the belt baffle can be adjusted in length and laterally to adjust the inclination of the metal baffle, accommodating coal feed at different heights and reducing spillage. Example

[0025] In this embodiment, the elastic support is an elastic steel plate 4. The rear end of the elastic steel plate 4 is fixed on the baffle frame 3, and the front end of the elastic steel plate 4 contacts the lower side of the metal base plate 1 and is squeezed and bent downward.

[0026] Specifically, the baffle frame is equipped with insertion slots. The bottom of the insertion slots is closed and horizontal. An elastic steel plate is inserted into the insertion slots, with a bend at the front end, and it abuts against the recessed part of the rear of the metal base plate. When coal splashes through, it will collide with the belt baffle. The belt baffle transmits the impact force to the elastic steel plate, which is then bent. At the same time, the lower part of the metal base plate and the rear of the belt baffle swing back, and the coal naturally falls into the conveyor, achieving the purpose of buffering and blocking coal. Example

[0027] In this embodiment, the elastic support includes a compression spring 5, a guide rod 6, and an elastic mounting bracket 7. The front end of the guide rod 6 is hinged to the lower rear side of the metal base plate 1. A limiting ring is provided at the front end of the guide rod 6. The compression spring 5 is sleeved on the limiting rod, and the front end of the compression spring 5 contacts the limiting ring. The rear end of the guide rod 6 passes through the through hole of the elastic mounting bracket 7, and the rear end of the compression spring 5 abuts against the elastic mounting bracket 7. The rear end of the guide rod 6 is threaded and cooperates with a nut 8. Adjusting the position of the nut 8 controls the compression of the compression spring 5.

[0028] In this device, the elastic mounting bracket 7 is an L-shaped plate with its top corner facing the rear. The upper edge is fixed to the baffle frame 3, and the guide rod 6 is inserted through the opening at the lower end. In the initial stage, the lower part of the L-shaped plate is parallel to the metal base plate.

[0029] When the angle of the metal base plate needs to be adjusted, adjust the position of the nut and move the guide rod backward. The metal base plate and the belt baffle move backward simultaneously. The vertical tilt angle of the metal base plate will decrease, and vice versa.

[0030] The baffle frame 3 of this device is a vertical frame structure. The top of the baffle frame 9 protrudes towards the conveyor side. The same ear plate holes are provided on the upper and lower rear parts of the metal base plate 1. The center of the ear plate hole on the upper rear part of the metal base plate 1 and the through hole of the ear plate 9 on the baffle frame 3 are aligned and a hinge shaft is inserted through it. The front end of the guide rod 6 is provided with a rotating shaft and inserted into the through hole of the ear plate hole on the lower rear part of the metal base plate 1.

[0031] The hinged structure allows for easy adjustment of the angle of the metal base plate and is used in conjunction with guide rods and nuts.

[0032] A mounting hole for the baffle is opened on the metal base plate 1, and a fixing hole is opened on the belt baffle 2. Bolts are installed in the mounting hole and fixing hole respectively to fix the metal baffle and the belt baffle 2.

[0033] This device consists of a metal base plate 1 and a belt baffle 2 installed on top of the conveyor, covering the upper exposed space of the conveyor. This serves to shield the left and right sides of the conveyor and the base plate, and to buffer the spillage of loose coal.

[0034] The elastic buffer structure of this device greatly buffers the impact force during the transportation of raw coal, reduces the wear and tear on the coal retaining plate, extends its service life, ensures the safety of raw coal transportation, and also saves production costs.

[0035] Adjusting the coal receiving angle of the coal retaining plate reduces coal spillage during operation, reduces the amount of cleaning work for employees, improves work efficiency, and achieves cleaner production.
