The side plates 4 located at the left and right ends of the first baffle 1 are provided with bolt holes for connecting the base plate.

[0004] Traditional coal chute retaining plates have the following problems: their structure is relatively complex, they are difficult to process, and their coal-blocking effect is not good. Due to their large usage underground, they also have problems such as complicated installation and maintenance, affecting the efficient transportation of coal, and increasing the labor intensity and safety risks of workers. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a coal chute retaining plate to solve the technical problems existing in the prior art.

[0006] The technical solution adopted by this utility model is as follows: a coal chute retaining plate, including a second baffle arranged in a vertical direction, the cross section of the second baffle in the vertical direction is "Z" shaped, and two or more fixing rods arranged in a vertical direction are fixed in parallel on the rear side of the vertical part of the second baffle. The lower end of the fixing rod extends beyond the lower end of the second baffle and is installed on the chute frame through a connecting plate.

[0007] Preferably, the second baffle is formed by bending A3 steel plate.

[0008] Preferably, the fixing rod is made of No. 8 channel steel.

[0009] Preferably, the middle part of the connecting plate is fixed perpendicularly to the fixing rod, and both ends of the connecting member are connected to the chute frame by bolts.

[0010] Preferably, the connecting plate is an 8mm iron plate.

[0011] Preferably, the overall length and overall height of the second baffle are 1600*300mm.

[0012] The beneficial effects of this utility model are:

[0013] 1. Compared with the prior art, this utility model optimizes the structure and improves the strength of the coal retaining plate structure.

[0014] 2. Compared with the prior art, the reasonable arc and angle of this utility model can better guide the coal flow, so that the coal can be transported more smoothly along the chute, reducing the accumulation and blockage of coal during transportation and ensuring the continuity of coal transportation.

[0015] 3. Compared with the prior art, this utility model uses an innovative design, has a simple structure, simple processing technology, convenient installation and maintenance, is safe and reliable, and reduces the labor intensity and safety risks of workers.

[0016] 4. Compared with the existing technology, this utility model can save 50 yuan per piece in terms of material saving, processing efficiency and reusability compared with the traditional chute coal retaining plate. The practical chute coal retaining plate is expected to cost 1,000 yuan per year for the whole mine, which will generate a benefit of 1,000 × 50 = 50,000 yuan / year. Attached Figure Description

[0021] The reference numerals in the accompanying drawings include: first baffle 1, first stiffener 2, second stiffener 3, side plate 4, second baffle 5, fixing rod 6, and connecting plate 7. Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1:

[0024] A type of coal chute retaining plate, such as Figures 3-4As shown, it includes a second baffle 5 arranged vertically. The vertical cross-section of the second baffle 5 is "Z" shaped. The second baffle 5 is made of A3 steel plate with a thickness of 3mm and bent. The overall length and overall height of the second baffle 5 are 1600*300mm. Two fixing rods 6 arranged vertically are fixed parallel to the rear side of the vertical part of the second baffle 5. The fixing rods 6 are 8# channel steel. The upper end of the fixing rods 6 is flush with the upper end of the second baffle 5. The lower end of the fixing rods 6 extends beyond the lower end of the second baffle 5. A connecting plate 7 arranged vertically is fixed to the lower end of the fixing rods 6. The connecting plate 7 is made of 8mm iron plate. The middle part of the connecting plate 7 is fixed vertically to the fixing rods 6. The two ends of the connecting plate are connected to the chute frame by bolts.

[0025] This utility model is made entirely of high-quality A3 steel plates. Two No. 8 channel steels are used on the back of the coal retaining plate to enhance the structural strength and also serve as supports for fixing to the chute. The whole structure is easy to process and install, and has good stability.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
