Description

Technical Field

[0001] The utility model relates to a coal grate, in particular to a coal grate which is applied in the field of coal logistics and is convenient for unloading. Background Art

[0002] Coal unloading ditches are indispensable facilities in coal mining, thermal power generation and other industries. They are mainly divided into train unloading ditches and automobile unloading ditches. The main structure of the coal unloading ditch is underground with a deep burial depth. During the production process, the coal transported by trains, automobiles and other equipment needs to be unloaded to the downstream transportation equipment through the coal unloading ditch. During the transportation and unloading process, in order to prevent large pieces of raw coal or other debris from directly impacting and damaging downstream equipment, it is necessary to use coal unloading grid plates to intercept large pieces of raw coal or other debris, and then use crushers and other equipment to crush the coal blocks before sending them to the raw coal receiving equipment.

[0003] In actual application, the existing coal grates are easily blocked due to the large volume of the coal mine, causing coal blocks to accumulate on the surface of the coal grate, which is not only inconvenient for unloading, but also requires a large amount of equipment and manpower to clear the blocked coal grate, thereby reducing the coal unloading efficiency, increasing the unloading cost, and being inconvenient for the staff to use. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the existing coal grate is easily blocked by large pieces of coal during the coal unloading process, which is not only inconvenient for unloading, but also requires a lot of manpower and material resources for cleaning, which reduces the coal unloading efficiency and is inconvenient for staff to use.

[0005] To solve the above problems, the utility model provides a coal grate which is convenient for unloading, comprising a transverse frame, a grid one is welded in the transverse frame, a vertical frame is fixedly connected to the rear part of the upper end of the transverse frame, two grids two are fixedly welded in the vertical frame, an inclined support rod is fixedly connected between the grid one and the grid two located at the right end, a plurality of crushing assemblies are fixedly connected to the upper end of the grid one, the crushing assemblies are located at the criss-crossing parts of the grid one, the crushing assemblies comprise a support seat, a containing tube is fixedly connected to the upper end of the support seat, a buffer pad is fixedly connected to the inner bottom wall of the containing tube, a spring is fixedly connected to the upper end of the buffer pad, a slide plate is fixedly connected to the upper end of the spring, a fixing rod is fixedly connected to the upper end of the slide plate, and the upper end of the fixing rod passes through the containing tube and is fixedly connected to the crushing head.

[0006] In the above-mentioned coal grate which is convenient for unloading, the coal blocks can be pre-crushed during the unloading process, which effectively reduces the situation where the coal blocks block the coal grate, thereby improving the coal unloading efficiency and facilitating the use of the staff.

[0007] As a further improvement of the present application, the upper end of the crushing head is conical and the crushing head is made of diamond.

[0008] As a further improvement of the present application, the longitudinal section of the support seat is an isosceles trapezoid, and the lower end of the support seat is fixedly connected to the upper end of the grille one.

[0009] As a further improvement of the present application, the grid width formed by grid one is greater than the grid width formed by grid two, and the height of grid one is less than the height of the transverse frame.

[0010] As another improvement of the present application, the lower end of grille one is fixedly connected to two support assemblies, the support assemblies include two fixed plates, the fixed plates are located at the criss-crossing parts of grille one, and the lower ends of the fixed plates are fixedly connected to support columns.

[0011] As another improved supplement of the present application, a support plate is provided below the two support columns, the upper end of the support plate is fixedly connected to a triangular guide box, and the lower end of the support column is fixedly passed through the guide box.

[0012] To sum up, in actual application, the transverse frame is installed at the upper end of the coal unloading ditch. During the coal unloading process, larger coal blocks fall from the top of grille one and collide with the crushing head. The crushing head with greater hardness can knock cracks on the surface of the coal blocks, and the larger coal blocks continue to move downward until they collide with grille one, thereby breaking the larger coal blocks into small coal blocks, which pass through grille one and fall into the coal unloading ditch. If there are coal blocks moving obliquely, the larger coal blocks will directly collide with grille two, causing them to fall back to the surface of grille one for crushing, and the smaller coal blocks can pass through grille two and fall into the coal grate at the other end, thereby improving the unloading efficiency of the coal grate and facilitating the use of the staff.

[0021] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0022] The first implementation method:

[0023] Figure 1 and Figure 2 The figure shows: a coal grate which is convenient for unloading, comprising a transverse frame 1, a grille 2 welded inside the transverse frame 1, a vertical frame 3 fixedly connected to the rear of the upper end of the transverse frame 1, two grilles 2 4 fixedly welded inside the vertical frame 3, the grille 2 4 can block the obliquely moving falling coal, so that larger coal blocks fall back to the top of the grille 2, thereby improving the coal unloading efficiency, an inclined support rod 5 fixedly connected between the grille 2 and the grille 2 4 located at the right end, the support rod 5 can support the grille 2 4, a plurality of crushing assemblies are fixedly connected to the upper end of the grille 2, and the crushing assemblies are located at the criss-crossing parts of the grille 2.

[0024] Figure 3 It is shown that the crushing assembly includes a support seat 6, the upper end of the support seat 6 is fixedly connected with a receiving tube 7, the inner bottom wall of the receiving tube 7 is fixedly connected with a buffer pad 8, the upper end of the buffer pad 8 is fixedly connected with a spring 9, the upper end of the spring 9 is fixedly connected with a slide plate 10, the upper end of the slide plate 10 is fixedly connected with a fixing rod 11, the upper end of the fixing rod 11 passes through the receiving tube 7 and is fixedly connected with a crushing head 12, when the crushing head 12 is hit, the fixing rod 11 moves downward, so that the slide plate 10 presses the spring 9 downward, thereby unloading the impact force, effectively avoiding the fixing rod 11 from being damaged by a large impact force, and extending the service life of the equipment, the upper end of the crushing head 12 is conical, and the crushing head 12 is made of diamond, the longitudinal section of the support seat 6 is an isosceles trapezoid, which can effectively prevent coal blocks from accumulating on the top of the support seat 6, and the lower end of the support seat 6 is fixedly connected to the upper end of the grid 2.

[0025] Figure 4 It is shown that the grid width formed by the grid 1 2 is greater than the grid width formed by the grid 2 4 , and the height of the grid 1 2 is less than the height of the transverse frame 1 .

[0026] When in use, the transverse frame 1 is installed at the upper end of the coal unloading ditch. During the coal unloading process, larger coal blocks fall from above the grid 2 and collide with the crushing head 12. The crushing head 12 with greater hardness can knock cracks on the surface of the coal blocks, and the larger coal blocks continue to move downward until they collide with the grid 2, thereby breaking the larger coal blocks into small coal blocks, which pass through the grid 2 and fall into the coal unloading ditch. If there are coal blocks moving obliquely, the larger coal blocks directly collide with the grid 2 4, causing them to fall back to the surface of the grid 2 for crushing, and the smaller coal blocks can pass through the grid 2 4 and fall into the coal grate at the other end, thereby improving the unloading efficiency of the coal grate and facilitating the use of the staff.

[0027] The second implementation method:

[0028] This embodiment is based on the first embodiment, and a supporting component is added, and the rest of the parts are consistent with the first embodiment.

[0029] Figure 5 and Figure 6 It is shown that: the lower end of the grille 2 is fixedly connected to two support assemblies, and the support assemblies shown include two fixed plates 13, the fixed plates 13 are located at the criss-crossing parts of the grille 2, and the lower ends of the fixed plates 13 are fixedly connected to support columns 14, which can support the grille 2 to improve the stability of the grille 2, and support plates 15 are provided below the support columns 14, and the upper ends of the support plates 15 are fixedly connected to triangular guide boxes 16, which can effectively prevent coal blocks from accumulating on the surface of the support plates 15, and the lower ends of the support columns 14 are fixedly passed through the guide boxes 16.

[0030] When in use, the support plate 15 is installed in the coal unloading ditch, and the grid 2 is supported by the support column 14 and the fixing plate 13, which effectively prevents the grid 2 from collapsing due to long-term coal falling and prolongs the service life of the coal grate.

[0031] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
