[0002] A vehicle coal unloading ditch is generally a ditch structure with an inclined bottom surface, the length and width of which are determined according to actual coal unloading capacity and vehicle types and other factors, and it usually has a certain depth to accommodate sufficient coal. A coal grate is usually arranged on the upper side of the coal unloading ditch, which is mainly installed above the vehicle coal unloading ditch and mainly functions to prevent large coal blocks, coal gangue or other foreign matters (such as wood blocks, metal blocks, etc.) from directly entering the coal unloading ditch.

[0003] The coal grate is usually arranged on the upper side of the coal unloading ditch, and then the transported coking coal is poured onto the coal grate. The coal with a particle size smaller than the gap of the grate can smoothly pass through the grate and fall into the coal unloading ditch. The coal blocks, coal gangue or other foreign matters with a particle size larger than the gap of the grate are intercepted on the coal grate. When the coal has a high moisture content, the coal particles are prone to adhere to each other during pouring. After being poured onto the coal grate, the coal particles can block the gaps of the coal grate, which can seriously affect the coal unloading efficiency. Therefore, it is usually necessary to manually use a shovel or the like to remove the coal blocks and foreign matters blocked on the grate, which has a complex cleaning process and requires a lot of labor.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1 —5 provides further detailed description of this application.

[0023] This application discloses a coal grate for a truck unloading ditch. For example... Figures 1-5 As shown, it includes a coal unloading ditch body 1, a coal grate body 2 is provided on the upper side of the coal ditch body 1, a hidden groove 3 is provided on the upper side of the coal grate body 2, a drive motor 4 is fixedly connected to one side of the inner wall of the hidden groove 3, a lead screw 5 is fixedly connected to the output end of the drive motor 4, a drive block 6 is threaded on the lead screw 5 and slides with the hidden groove 3, and a scraper 7 is fixedly connected to the upper side of the drive block 6.

[0024] A collection trough 8 is provided on the upper side of the coal grate body 2. A storage frame 9 is provided inside the collection trough 8. A protective component 10 is provided on the upper side of the storage frame 9. Multiple unblocking mechanisms 11 are provided on one side of the scraper 7.

[0025] Please see Figure 3 The protective component 10 includes a movable groove 101 formed on the storage frame 9, a sealing cover 102 that slides on the inner wall of the movable groove 101, and a compression spring 103 that is fixedly connected between the sealing cover 102 and the movable groove 101. The sealing cover 102 is compressed by the compression spring 103, thereby protecting the upper side of the storage frame 9.

[0026] Please see Figure 5 The unblocking mechanism 11 includes a U-shaped frame 111 fixedly connected to one side of the scraper 7, a linkage rod 112 rotatably fitted to the inner wall of the U-shaped frame 111, a lower pressure plate 113 fixedly connected to the linkage rod 112, a force-bearing block 114 fixedly connected to one end of the linkage rod 112, and a torsion spring 115 fixedly connected between the force-bearing block 114 and the U-shaped frame 111. The torsion spring 115 exerts force on the force-bearing block 114 and the linkage rod 112, thereby enabling the lower pressure plate 113 to always exert downward force. When the lower pressure plate 113 enters the gap of the coal grate body 2, its pressure cleans the impurities blocking the gap.

[0027] Please see Figure 2A top pressure plate 12 is fixedly connected to one side of the scraper 7. One end of the top pressure plate 12 is engaged with the sealing cover 102. When the scraper 7 moves, the top pressure plate 12 will squeeze the sealing cover 102 to open the sealing cover 102.

[0028] Please see Figure 2 A protective plate 13 is rotatably fitted on the upper side of the coal grate body 2. The protective plate 13 is located on the upper side of the hidden trough 3. An arc-shaped extrusion block 14 that cooperates with the protective plate 13 is provided on one side of the scraper 7. The arc-shaped extrusion block 14 can protect the upper side of the hidden trough 3 and reduce the amount of coking coal entering the interior of the hidden trough 3. When the scraper 7 moves, the arc-shaped extrusion block 14 can automatically extrude and push open the protective plate 13.

[0029] Please see Figure 4 Two electric push rods 15 are fixedly connected to one side of the scraper 7. A pressing plate 16 is fixedly connected to the output end of the two electric push rods 15. The pressing plate 16 cooperates with the lower pressure plate 113. When 78 is reset, the pressing plate 16 can be pressed by the electric push rods 15 to press the lower pressure plate 113, so that the lower pressure plate 113 and the coal grate body 2 will not be limited during the reset process.

[0030] Please see Figure 2 A reinforcing rib 17 is fixedly connected to the lower side of the inner wall of the coal grate body 1. The upper side of the reinforcing rib 17 is connected to the coal grate body 2. The reinforcing rib 17 can increase the load on the middle part of the coal grate body 2 and improve the stability under load.

[0031] The implementation principle of a coal grate for unloading coal in a truck according to an embodiment of this application is as follows: when in use, coking coal is poured onto the upper side of the coal grate body 2, and filtered through the gaps reserved on the coal grate body 2, so that larger materials fall into the interior of the coal trench body 1.

[0032] After the coal is poured out, the drive motor 4 can be started to drive the lead screw 5 to rotate, thereby moving the drive block 6 and the scraper 7. The scraper 7 can scrape off the coking coal or impurities remaining on the upper side of the coal collection grate body 2, so that the coking coal that was originally blocking the gaps can fall out from other gaps. Larger impurities are automatically scraped off, so that the impurities fall into the storage frame 9 in the collection tank 8 for collection, which is convenient for subsequent unified processing, realizing automatic cleaning and saving the time and manpower of manual cleaning.

[0033] As the scraper 7 moves, it simultaneously presses against the pressure plate 12, causing the sealing cover 102 to open prematurely. After the movement ends, the pressure spring 103 presses the sealing cover 102 back to its original position.

[0034] During the movement of the scraper 7, the corresponding torsion spring 115 will deliver downward torque to the force block 114, so that the lower pressure plate 113 can protrude into the gap during the movement, thereby cleaning the blocked gap during the scraping process, further reducing labor costs and labor intensity.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
