[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0025] Example:
[0026] Please refer to Figures 1 to 4 This utility model provides a quick-opening casing for a hammer crusher, which aims to solve the problems of cumbersome opening and closing of existing hammer crusher casings and time-consuming and labor-intensive maintenance.
[0027] like Figure 1 As shown, the quick-opening casing of the hammer crusher includes a housing 1 and a top cover 2 rotatably connected to the top of the housing 1 via a hinge 9. The core component of the quick-opening casing is a quick-opening linkage mechanism, such as... Figure 1 , Figure 2 and Figure 3As shown, the quick-opening linkage mechanism includes an electric push rod 10 fixedly connected to one side of the housing 1, two sliders 11 slidably connected inside the housing 1, a connecting rod 12 rotatably connected to the opposite sides of the two sliders 11, a connecting frame 15 fixedly connected to the outside of the top cover 2, a connecting rod 13 rotatably connected between the middle of the connecting rod 12 and the inner wall of the housing 1, and a rotating rod 14 rotatably connected between the top of the connecting rod 13 and the outside of the connecting frame 15. One of the sliders 11 is fixedly connected to the output end of the electric push rod 10, and the connecting frame 15 is rotatably connected to the end of the connecting rod 12 away from the slider 11.
[0028] Specifically, the housing of the electric push rod 10 is fixed to one side of the outer wall of the housing 1, and its output end extends into the housing 1, serving as the drive source for the entire quick-opening linkage mechanism. Two sliders 11 are symmetrically arranged on the guide rail inside the housing 1, sliding along the length of the guide rail. The two ends of the connecting rod 12 are rotatably connected to the opposite sides of the two sliders 11, forming a retractable linkage bottom edge. The connecting frame 15 serves as a rigid support, its base fixed to the outer surface of the top cover 2, providing a stable rotational connection point for the linkage between the connecting rod 12 and the rotating rod 14. The bottom of the connecting rod 13 is rotatably connected to... The inner wall of the housing 1 serves as one of the fixed rotation fulcrums of the entire linkage mechanism. Its top is rotatably connected to the middle of the connecting rod 12. One end of the rotating rod 14 is rotatably connected to the top of the connecting rod 13, and the other end is rotatably connected to the outer side of the connecting frame 15. Through coordinated motion, the displacement of the linkage mechanism is effectively transmitted to the top cover 2. With this structural layout, the linear extension and retraction motion of the electric push rod 10 is ultimately converted into a large-angle rotation motion of the top cover 2 around the hinge 9 through the linkage of the slider 11, connecting rod 12, connecting rod 13, rotating rod 14 and connecting frame 15.
[0029] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the quick-opening casing of the hammer crusher also includes a feeding anti-blocking mechanism, and the feeding anti-blocking mechanism and the aforementioned housing 1 form a specific structural cooperation and connection relationship.
[0030] Please refer to the following carefully. Figure 1 and Figure 4 The core structure is described in detail below: The feeding anti-blocking mechanism includes a feeding hopper 3 fixedly connected inside the housing 1. The feeding hopper 3 has an inlet at the top and an outlet at the bottom. Multiple diversion plates 4 are fixedly connected to the top of the feeding hopper 3. The feeding anti-blocking mechanism also includes a limiting frame 5 fixedly connected to the bottom of the feeding hopper 3. The limiting frame 5 is also fixedly connected to the inner wall of the housing 1. A vibration motor 6 is installed in the middle of the limiting frame 5. A buffer pad 7 is fixedly connected to the top of the vibration motor 6. The buffer pad 7 abuts against the outer wall or bottom of the feeding hopper 3. Its function is to stably transmit vibration to the feeding hopper 3 when the vibration motor 6 is working, so as to prevent material from blocking in the feeding hopper 3.
[0031] Meanwhile, to provide power to the crusher, a drive motor 16 is also fixedly connected inside the housing 1. The output end of the drive motor 16 is fixedly connected to the main transmission block 17 and the main transmission block 18. The specific internal structure of the drive motor 16 is a well-known technology in the field and will not be described in detail here.
[0032] Based on the above embodiments, the present invention may further include the following preferred technical solutions:
[0033] In a preferred embodiment, a drive shaft 21 is rotatably connected inside the housing 1. An auxiliary transmission block 19 is fixedly connected to one end of the drive shaft 21 near the drive motor 16. A transmission belt 20 is sleeved between the main transmission block 17 and the auxiliary transmission block 19 to transmit the power of the drive motor 16 to the drive shaft 21, thereby driving the crushing component. Multiple mounting plates 22 are fixedly connected to the outside of the drive shaft 21 along its length. Four mounting rods 23 are installed between the multiple mounting plates 22. Hammer blades 24 are fixedly connected to the outside of each of the four mounting rods 23. The hammer blades 24 are the core working components in the crushing process. The stability of the hammer blades during high-speed rotation is ensured by the mounting rods 23 and the mounting plates 22.
[0034] In another preferred embodiment, a curved mesh 28 is fixedly connected inside the housing 1. The curved mesh 28 is arc-shaped and located below the drive shaft 21. The curved mesh 28 serves as a screening component for particle size classification of the crushed material. Only materials that meet the particle size requirements can pass through the curved mesh 28.
[0035] In another preferred embodiment, two guide plates 27 are fixedly connected inside the housing 1. The two guide plates 27 are arranged in a V-shape and are located between the curved mesh 28 and the auger 26 located below it. The guide plates 27 are used to collect and guide qualified materials passing through the curved mesh 28 so that they fall accurately into the auger 26 below.
[0036] In another preferred embodiment, an auger 26 is rotatably connected inside the housing 1. An auxiliary transmission block 25 is fixedly connected to one end of the auger 26 near the drive motor 16. A transmission belt 20 is sleeved between the main transmission block 28 and the auxiliary transmission block 25 to transmit the power of the drive motor 16 to the auger 26. A discharge port 8 is provided on the side wall of the housing 1, which communicates with the end of the auger 26. The auger 26, as a conveying component, collects qualified materials from below the guide plate 27 and conveys them to the discharge port 8 for discharge.
[0037] Working principle: During crushing operations, drive motor 16 starts, and its output simultaneously drives main drive block 17 and main drive block 28 to rotate. Main drive block 17 drives auxiliary drive block 19 via drive belt 20, which in turn drives drive shaft 21 to rotate at high speed. Drive shaft 21 drives multiple hammers 24 to rotate at high speed via mounting plate 22 and mounting rod 23. Main drive block 28 drives auxiliary drive block 25 via drive belt 20, which in turn drives auger 26 to rotate. Material enters from feed hopper 3. After being dispersed by the diverter plate 4, the vibrating motor 6 starts working. The vibration is transmitted to the limit frame 5 and the feed hopper 3 through the buffer pad 7 to prevent material blockage. After entering the crushing chamber, the material is crushed by the high-speed rotating hammer 24. The crushed material falls onto the curved mesh 28 located below the drive shaft 21. The material that meets the particle size requirements passes through the curved mesh 28 and falls into the V-shaped guide plate 27. The guide plate 27 guides the material to the auger 26. The rotating auger 26 pushes the material to the discharge port 8 opened on the side wall of the box 1 and connected to the end of the auger 26 for discharge.
[0038] When it is necessary to repair or replace the hammer blade 24 and the bending mesh 28, the electric push rod 10 is activated to retract it. The output end of the electric push rod 10 pulls the slider 11 connected to it to move along the guide rail. The slider 11 drives the connecting rod 12 to move. The connecting rod 12 is linked by a linkage mechanism consisting of the connecting rod 13, the rotating rod 14 and the connecting frame 15. This linkage mechanism converts the linear motion of the electric push rod 10 into the rotational motion of the top cover 2, so that the top cover 2, which is fixed with the connecting frame 15, rotates smoothly upward around the hinge 9, thereby quickly opening the box 1. After the repair is completed, the electric push rod 10 is activated to extend it. The linkage mechanism moves in the opposite direction, driving the top cover 2 to rotate downward around the hinge 9 to close and restore the sealing state.
[0039] 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 variations 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.
