[0017] Example: Figure 1-4As shown, the utility model provides a new explosion-proof and flameproof loader, including a frame 1, a protective box 11 is fixedly installed on the top of the frame 1, and symmetrically distributed empty slots 12 are opened on the top of the protective box 11, and evenly distributed heat dissipation slots 13 are opened on both sides of the protective box 11 and the two empty slots 12, and filter plates 14 are detachably installed inside the empty slots 12, and symmetrically distributed positioning holes 15 are opened on both sides of the filter plate 14, and symmetrically distributed brackets 16 are fixedly installed on both sides of the protective box 11 close to the heat dissipation slots 13, and symmetrically distributed positioning rods 17 are movably penetrated through the outer side of the brackets 16, and the two positioning rods 17 penetrate the outer side of the protective box 11 and are located in the empty slots 12, and the outer sides of the two positioning rods 17 are fixedly installed with snap rings 18, and the snap ring 18 and the protective box 11 are fixedly connected by a first spring 19, and a connecting plate 191 is fixedly installed at one end of the two positioning rods 17 away from the protective box 11.

[0018] Support rods 2 are slidably provided at the four corners of the top of the frame 1, and a stabilizing plate 21 is fixedly installed on the tops of the multiple support rods 2. Hydraulic rods 22 and second springs 23 are fixedly installed at the four corners of the top of the stabilizing plate 21. A blocking plate 24 is fixedly installed on the tops of the multiple hydraulic rods 22, and the second spring 23 and the blocking plate 24 are fixedly connected.

[0019] Both sides of the frame 1 are fixedly installed with symmetrically distributed mounting plates 3, and the tops of the mounting plates 3 and the frame 1 are provided with slide grooves 31, and the bottom of the support rod 2 is movably clamped in the slide groove 31. By setting the mounting plates 3 and the slide grooves 31, the support rod 2 can be moved to prevent the stabilizing plate 21 and the blocking plate 24 from affecting the filter plate 14 from being placed in the empty slot 12.

[0020] A through hole 4 is provided at the bottom of the support rod 2 and the lower surface of the inner wall of the slide groove 31. A latch 41 is provided inside the through hole 4 for matching use. By providing the through hole 4 and the latch 41, the support rod 2 can be fixed to avoid displacement and improve stability.

[0021] An observation window 5 is fixedly installed on one side of the protection box 11 away from the heat dissipation slot 13 . The observation window 5 is made of a transparent material. By setting the observation window 5 , the working condition of the engine inside the protection box 11 can be seen.

[0022] Circular grooves 6 are provided on both sides of the protection box 11 and in the two empty grooves 12. Fans 61 are provided in the circular grooves 6. By providing the circular grooves 6 and the fans 61, the high temperature inside the protection box 11 can be discharged, thereby increasing the service life of the engine.

[0023] The lower surface of the inner wall of the protective box 11 is slidably provided with symmetrically distributed movable plates 7, and fixed blocks 71 are fixedly installed on the opposite sides of the two movable plates 7. A fixing hole 72 is opened at the top of the fixed block 71. The engine can be clamped by the two movable plates 7, and the fixed blocks 71 and the fixed holes 72 are set so that it can be fixed by fixing screws, thereby improving the stability of the engine and preventing it from deflecting.

[0024] The bottom ends of the two movable plates 7 are fixedly mounted with symmetrically distributed clamping rods 8, and the lower surface of the inner wall of the protective box 11 is provided with symmetrically distributed clamping grooves 81, in which the clamping rods 8 are movably clamped. By setting the clamping rods 8 and the clamping grooves 81, the stability of the movable plates 7 during movement is improved.

[0025] Working principle: In actual use, the connecting plate 191 is pulled away from the protection box 11, driving the positioning rod 17 to disengage from the empty slot 12, and at the same time, the snap ring 18 outside the positioning rod 17 stretches the first spring 19. At this time, the filter plate 14 is placed in the empty slot 12, and the tension on the connecting plate 191 is stopped, so that the first spring 19 is reset and drives the positioning rod 17 to move toward the protection box 11 through the snap ring 18. The positioning rod 17 enters the empty slot 12 and enters the positioning hole 15, completing the installation of the filter plate 14; The stabilizing plate 21 and the blocking plate 24 are arranged to block the gravel and prevent the gravel from damaging the protective box 11 and the engine inside. When the gravel falls onto the blocking plate 24, the blocking plate 24 moves downward and compresses the second spring 23, so that the second spring 23 absorbs part of the impact force. Then the second spring 23 releases the elastic force, thereby reducing the impact force borne by the blocking plate 24. The hydraulic rod 22 is arranged to reduce the rebound speed of the second spring 23, thereby preventing the gravel from bouncing too much and falling on the staff.

[0026] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
