Detailed Implementation

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

[0023] like Figures 1 to 3As shown, a preferred embodiment of the centralized discharge rock blasting test device of this utility model includes a frame 1, a test support plate 2, a protective box 3, and a lifting driver 41. The connecting end of the test support plate 2 is rotatably mounted on the frame 1. The test support plate 2 is used to support the blasted rock model and collect the blasted debris. The lifting driver 41 is mounted on the frame 1 and is used to lift the test support plate 2, causing the test support plate 2 to tilt, so as to dump the debris on the test support plate 2. The lifting driver 41 is usually a cylinder, but in other embodiments, a hydraulic cylinder or electric cylinder or other lifting device can also be used. The protective box 3 is placed on the frame 1 and covers the test support plate 2. The protective box 3 is used to limit the location of the debris during blasting, ensuring that all the debris falls on the test support plate 2. The protective box 3 is equipped with a front door 31. The connection end of the front door 31 and the test support plate 2 is located on the same side of the protective box 3. The bottom surface of the front door 31 is lower than the top surface of the test support plate 2, thus ensuring that all the gravel can fall off the test support plate 2. There are two protective boxes 3, two test support plates 2, and two lifting actuators 41. Each test support plate 2 corresponds to one protective box 3 and one lifting actuator 41, so that two sets of tests can be performed simultaneously, improving test efficiency. Of course, in other embodiments, one test support plate 2 or more test support plates 2 can be set on the frame 1, with each support plate corresponding to one protective box 3 and one lifting actuator 41. The number of test support plates 2 can be set according to the requirements.

[0024] Combination Figure 4 Referring to the reference, the frame 1 includes a frame body 11, a support plate 12, and a support plate 13, both of which are mounted on the frame body 11. The support plate 13 is located below the support plate 12, and the lower end of the lifting drive 41 is pivotally connected to the support plate 13. The support plate 12 is used to place items and has a clearance notch. The test support plate 2 is located within the clearance notch, and the output end of the lifting drive 41 passes through the frame body 11 and connects to the test support plate 2. The test support plate 2 is provided with a drive connecting plate 21, which is used to connect to the lifting drive 41. The lifting drive 41 is connected to a connecting shaft that is connected to the drive connecting plate 21, meaning that the connecting shaft on the lifting drive 41 is rotatably mounted on the drive connecting plate 21.

[0025] The connecting end of the test support plate 2 is provided with an arc surface to ensure that the connecting end can rotate smoothly during rotation and to ensure that it will not interfere with the frame 1.

[0026] The frame 1 is provided with a rotating shaft connecting plate 14, and the connecting end of the test bearing plate 2 is provided with a shaft rod, which is rotatably connected to the rotating shaft connecting plate 14.

[0027] like Figure 5 As shown, the protective box 3 has a positioning notch 32 on its upper surface, facing downwards. The positioning notch 32 is used to cooperate with the rotating shaft connecting plate 14 to fix the protective box 3 and prevent it from moving. The protective box 3 is equipped with a front door actuator 42, which is pivotally connected to the protective box 3. The output end of the front door actuator 42 is pivotally connected to the front door 31. The front door actuator 42 is usually a pneumatic cylinder, but it can also be a hydraulic cylinder or an electric cylinder. When the front door actuator 42 extends, the front door 31 closes; when the front door actuator 42 retracts, the front door 31 opens, allowing the actuator to reach into the protective box 3 for operation.

[0028] like Figure 6 As shown, when it is necessary to collect gravel, the container or equipment for collecting gravel is placed below the front door 31. The front door actuator 42 extends to open the front door 31, and then the lifting actuator 41 lifts the rear end of the test support plate 2, causing the test support plate 2 to tilt, thereby pouring the gravel out into the gravel collection container or equipment. After completion, the lifting actuator 41 resets, causing the test support plate 2 to reset, facilitating the next test. This method can quickly collect gravel, is convenient and fast, and requires no manual collection.
