[0021] like Figures 1 to 4As shown, this utility model discloses a graded crushing and recycling aggregate concrete preparation equipment, including a main body 1 and a feeding pipe 2. The feeding pipe 2 is located at the bottom of the main body 1. The equipment also includes a mounting frame 3, a feeding plate 4, two sets of guide components, and a buffer mechanism. The bottom of the main body 1 is connected to the top of the mounting frame 3. A U-shaped groove is provided at the front end of the mounting frame 3, and the outer side of the feeding pipe 2 is fitted into the U-shaped groove of the mounting frame 3. The rear end of the feeding plate 4 is slidably attached to the rear end of the U-shaped groove of the mounting frame 3. The left and right ends of the feeding plate 4 are slidably attached to one end of the U-shaped groove of the mounting frame 3 via guide components. A buffer mechanism is provided at the bottom of the feeding plate 4. The feeding pipe at the bottom of the main body is fitted into the U-shaped groove of the mounting frame. The rear end of the feeding plate is slidably attached to the rear end of the U-shaped groove. The left and right ends are slidably connected to the U-shaped groove via guide components. The bottom is supported by the buffer mechanism. When material falls from the feeding pipe, the feeding plate receives the material and can move along the U-shaped groove. The sliding groove and buffer mechanism absorb the impact of materials, preventing the material discharge plate from shaking violently. This eliminates the need for workers to place the receiving container under the device, improving the convenience of receiving materials and thus increasing the efficiency and effectiveness of concrete preparation, thereby enhancing its practicality.
[0022] As a preferred embodiment of the above, the guiding component includes two sets of guide blocks 5. A set of sliding grooves is provided at both ends of the U-shaped groove of the mounting frame 3. The two sets of guide blocks 5 are slidably connected to the set of sliding grooves respectively. The left and right ends of the feeding plate 4 are respectively connected to the other end of a set of guide blocks 5. When the feeding plate slides, the guide blocks slide synchronously in the sliding grooves, restricting the feeding plate to move only up and down along the U-shaped grooves, ensuring accurate movement direction, ensuring smooth sliding of the feeding plate, avoiding deviation that causes material spillage, improving the receiving accuracy, and thus enhancing practicality.
[0023] As a preferred embodiment of the above, the buffer mechanism includes a mounting block 6, a support plate 7, two sets of sliding rods 8, two sets of first springs 9, two sets of first sliders 10, two sets of connecting plates 11, a hinge assembly, and an auxiliary mechanism. The rear bottom of the U-shaped groove of the mounting bracket 3 is connected to the rear end of the support plate 7. A set of sliding grooves is provided on the front and rear sides of the top of the support plate 7, and a set of sliding rods 8 is provided on each of the two sets of sliding grooves. The two sets of first sliders 10 are slidably connected to the corresponding sliding grooves through the sliding rods 8. The outer ends of the two sets of sliding rods 8 are respectively fitted inside the set of first springs 9, and the two ends of the two sets of first springs 9 are respectively connected to the first sliders 10 and one end of the sliding groove. Next, the tops of the two sets of connecting plates 11 are respectively connected to the tops of a set of first sliders 10. The tops of the two sets of connecting plates 11 are respectively hinged to the bottom of the mounting block 6 through a hinge assembly. The top of the mounting block 6 is connected to the rear end of the bottom of the feeding plate 4. A set of auxiliary mechanisms are respectively provided at the left and right ends of the top of the support plate 7. When the material falls and impacts the feeding plate, the feeding plate presses down on the mounting block, and drives the connecting plate and the first slider to slide on the slide rod through the hinge assembly, compressing the first spring. The damping rod consumes the impact energy. After the impact, the first spring resets, pushing the feeding plate back to its original position, reducing the vibration of the feeding plate and reducing material splashing, thus enhancing practicality.
[0024] As a preferred embodiment of the above, the hinge assembly includes multiple sets of hinge seats 12 and four sets of support rods 13. The tops of the two sets of connecting plates 11 are respectively hinged evenly through one end of the two sets of hinge seats 12 and support rods 13, and the bottoms of the mounting blocks 6 are respectively hinged through the other four sets of hinge seats 12 and support rods 13. When the material plate is impacted and pressed down, the support rods rotate around the hinge seats to adjust the angle between the connecting plates and the mounting blocks, making the buffering process more flexible and thus enhancing practicality.
[0025] As a preferred embodiment of the above, the auxiliary mechanism includes four sets of fixing blocks 14, four sets of connecting rods 15, and a telescopic assembly. The top left and right ends of the support plate 7 are respectively connected to the bottom of one set of fixing blocks 14. The top of each of the two sets of fixing blocks 14 is provided with a set of grooves. The bottom of the grooves of the two sets of fixing blocks 14 are respectively connected to the bottom of the connecting rods 15 through the telescopic assembly. The top of each of the two sets of connecting rods 15 is respectively connected to one side of the bottom of the feeding plate 4. When the feeding plate is impacted, the connecting rods press down on the telescopic assembly, and the damping rods and the second spring are compressed to absorb the lateral impact energy. After the impact, the second spring pushes the connecting rods to reset, assisting the first spring to prevent the feeding plate from swaying left and right, ensuring stable material receiving. This is especially suitable for impact scenarios involving large aggregate particles, thus enhancing its practicality.
[0026] As a preferred embodiment of the above, the telescopic assembly includes two sets of second springs 16 and two sets of damping rods 17. The bottom of the grooves of the two sets of fixing blocks 14 are respectively connected to the bottom of the damping rods 17, and the bottom of the two sets of connecting rods 15 are respectively connected to the top of the damping rods 17. A connecting spring is provided on the outer side of each of the two sets of damping rods 17, and the bottom of the outer side of the two sets of connecting rods 15 are respectively slidably fitted with the corresponding grooves of the fixing blocks 14. The connecting rods drive the damping rods to slide in the grooves, the second springs are compressed to absorb energy, and the damping rods limit the sliding speed to avoid violent shaking of the feed plate. The damping rods cooperate with the second springs to effectively buffer lateral impacts, thus enhancing practicality.
[0027] As a preferred embodiment of the above, the top of the feeding plate 4 has an inclined angle; it guides the material to slide in a specified direction, which facilitates the centralized collection of the material and avoids accumulation, thus enhancing its practicality.
[0028] This utility model discloses a graded crushing and recycled aggregate concrete preparation equipment. During operation, the receiving container is placed at a suitable position on one side of the feeding plate. The material falls from the feeding pipe at the bottom of the main body of the device and impacts the top of the feeding plate. After being impacted, the feeding plate is pressed down by the mounting block of the buffer mechanism, the connecting plate and the first slider are compressed, the first spring is compressed, and the damping rod dissipates energy. At the same time, the telescopic component of the auxiliary mechanism absorbs the lateral impact and reduces the shaking of the feeding plate. The tilt angle of the top of the feeding plate guides the material to slide and fall into the receiving container until the receiving is completed. Before completing the above actions, it is first moved to the position required by the user.
[0029] The terms “vertical,” “horizontal,” “left,” “right,” and similar expressions used in this article are for illustrative purposes only.
[0030] In this utility model, the terms "first," "second," and "third" do not represent a specific quantity or order, but are merely used to distinguish names.
[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
