This not only damages the blades on the crusher, but also damages the transmission device of the entire formwork crusher. Furthermore, the feed inlet of existing formwork crushers is either wide-open or non-existent, which can easily lead to the flying of iron nails and damage to the blades during the crushing process, creating significant safety hazards. Utility Model Content

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] like Figure 1-10 As shown, a formwork crushing device includes: a feeding bin 1, a movable bin 2, a double-acting hydraulic cylinder 3, and a crushing component 4, wherein:

[0034] The aforementioned feed hopper is fixedly installed on the machine base 6, and the aforementioned movable feed hopper 2 is located below the feed hopper;

[0035] The aforementioned mobile hopper 2 rolls on the machine base, and the rolling contact method can be, but is not limited to, rollers and guide rails; the aforementioned mobile hopper is provided with bottom plates 201 on both sides, which are used to receive the falling templates; the aforementioned mobile hopper is provided with a baffle in the middle area, and a connecting seat 203 is provided on the baffle; the aforementioned mobile hopper is provided with wall panels around its perimeter.

[0036] The aforementioned double-acting hydraulic cylinder 3 is fixedly installed on the machine base 6; the aforementioned double-acting hydraulic cylinder 3 drives the moving hopper 2 through the connecting seat 203, and the aforementioned double-acting hydraulic cylinder 3 drives the moving hopper 2 to move;

[0037] The aforementioned crushing component 4 is located below the middle area of ​​the mobile hopper, and the aforementioned crushing component 4 can crush the building template;

[0038] The hydraulic component 7 drives the aforementioned double-acting hydraulic cylinder 3, and the drive motor 5 drives the crushing component 4 through a pulley or sprocket transmission structure.

[0039] During operation, external conveying equipment, such as a material grabber, feeds formwork and other materials into the device through the upper part of the feeding hopper. The materials then sequentially pass through a moving hopper into the crushing unit for crushing. During this process, the bottom plate of the moving hopper catches the falling formwork, and a double-acting hydraulic cylinder drives the moving hopper to move left and right. A pusher plate is installed inside the moving hopper. As the hopper moves left and right, the formwork falls into the crushing unit under the action of the pusher plate, where it is hammered into fragments and finally discharged through a screen. This enables large-scale industrial crushing of construction formwork.

[0040] Example 2

[0041] As an improvement to Embodiment 1 of this utility model, such as Figure 1-2 As shown in Figures 8-9, the main body of the aforementioned crushing component is a crushing spindle, and a breaker hammer 401 is fixedly connected to the surface of the aforementioned crushing spindle. The aforementioned breaker hammers 401 are arranged in a herringbone pattern on the surface of the crushing spindle. A screen should preferably be provided on the outer side of the aforementioned crushing spindle.

[0042] like Figure 1 , 9 As shown, the aforementioned screen should be installed in the trough area of ​​the frame, and the troughs are of different heights, with the left trough being lower than the right trough, and the screen is installed between the left and right troughs.

[0043] The herringbone arrangement can effectively improve the stress condition of the breaker and the main shaft, and enhance the crushing effect of the template.

[0044] The left pusher plate of the moving hopper pushes the template in the left trough towards the crushing shaft, and the template is crushed into qualified wood blocks that fall from below the machine. After reaching the designated position or the limit block, the right pusher plate of the moving hopper pushes the template in the right trough towards the crushing shaft, and the template is crushed into qualified wood blocks that fall from below the machine.

[0045] Example 3

[0046] As an improvement to Embodiment 1 of this utility model, such as Figure 1-2 As shown in Figures 8-10, the aforementioned base 6 is provided with a guide rail 601 and a limiting block 602, with the limiting block 602 located at both ends of the guide rail 601; the aforementioned movable hopper 2 is provided with rollers 202, which cooperate with the guide rail 601 to achieve rolling friction contact.

[0047] Limit blocks restrict the maximum movement distance of the mobile hopper, improving safety. The combination of rollers and guide rails effectively reduces the power requirements of the mobile hopper.

[0048] In this way, the mobile hopper can evenly and stably transport the accumulated waste templates to the crushing components, achieving stable and reliable operation.

[0049] Example 4

[0050] As an improvement to Embodiment 1 of this utility model, such as Figure 1-2 As shown in Figures 5-7, the aforementioned double-acting hydraulic cylinder 3 is provided with pulley blocks 301 and wire ropes at both ends. One end of the aforementioned wire rope is fixedly connected to the two side wall panels of the movable hopper, and the other end of the aforementioned wire rope passes around the pulley blocks and is fixedly connected to the machine base 6.

[0051] During operation, the hydraulic component 7 drives the aforementioned double-acting hydraulic cylinder 3, which moves the hopper left and right through a pulley system and wire rope.

[0052] This utility model is not limited to the above embodiments. Any technical solution formed by equivalent substitution or equivalent replacement shall fall within the scope of protection claimed by this utility model.
