Description

Technical Field

[0001] This utility model relates to the field of waste crushing technology, and more specifically, to a waste crushing equipment. Background Technology

[0002] Waste crushing equipment can recycle waste stone materials from the demolition of old asphalt or cement pavements.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this utility model.

[0023] like Figures 1 to 5 As shown, the waste crushing equipment provided by this utility model includes a waste crushing box 1. A first set of crushing rollers 2 are rotatably connected inside the front and rear walls of the waste crushing box 1. A first partition 3 is fixedly connected to the inner wall of the left side of the waste crushing box 1. A second partition 4 located to the right of the first partition 3 is fixedly connected to the inner wall of the waste crushing box 1. A screening structure located below the first set of crushing rollers 2 is provided inside the waste crushing box 1. The screening structure includes a U-shaped screen plate 13. A first motor 5 is fixedly installed on the outer left side of the waste crushing box 1. An auger 6 is fixedly connected to the output shaft of the first motor 5. A large stone discharge port 7 is opened in the middle of the first partition 3. A discharge support plate 8 is fixedly connected to the right side of the first partition 3. A second set of crushing rollers 9 located between the first partition 3 and the second partition 4 are rotatably connected inside the front and rear walls of the waste crushing box 1. The right end of the auger 6 is rotatably connected to the inside of the second partition 4. A drive structure is provided at the rear end of the waste crushing box 1. The drive structure is drivenly connected to the first set of crushing rollers 2 and the second set of crushing rollers 9.

[0024] When it is necessary to crush waste stones, the stones are fed into the feed inlet at the top left of the waste crushing box 1. The stones will undergo the first round of crushing under the action of the first set of crushing rollers 2, and the stones will be divided into two parts: the first part is fully crushed stones, and the second part is insufficiently crushed stones. Both parts of the stones will fall onto the surface of the U-shaped screen plate 13. Due to the design of the U-shaped screen plate 13, the stones falling from both ends slide down the upper surface of the U-shaped screen plate 13, while the fully crushed stones will... Stones falling through the holes on the surface of the U-shaped screen plate 13 are collected below it. Stones that are not fully crushed fall to the upper surface of the lower part of the U-shaped screen plate 13. At the same time, the first motor 5 is started when the stones are fed in. The operation of the first motor 5 drives the auger 6 to rotate. The auger 6 is located at the lower part of the U-shaped screen plate 13, thus pushing the stones that are not fully crushed to the large stone outlet 7. Under the action of the discharge plate 8, the stones are sent to the second set of crushing rollers 9 for a second round of crushing and are then collected.

[0025] By designing the U-shaped screen plate 13, the time that stones spend on the upper surface of the U-shaped screen plate is increased, resulting in more thorough screening. By starting the first motor 5, the auger 6 is driven to rotate, which pushes the large stones located on the lower upper surface of the U-shaped screen plate 13 to the large stone discharge port, and finally to the upper surface of the discharge tray 8. Due to gravity, they are sent to the second set of crushing rollers for secondary crushing. Compared with traditional devices, this device uses finer screening and classification, resulting in more thorough crushing of the crushed stone and more uniform crushed stone material.

[0026] The screening structure also includes a fixed plate 10 fixedly connected to the inner wall of the waste crushing box 1. A slide rod 11 is fixedly connected to the upper surface of the fixed plate 10. The other end of the slide rod 11 passes through the U-shaped screen plate 13 and is movably connected to it. A spring 12 is fixedly connected between the fixed plate 10 and the U-shaped screen plate 13. The spring 12 is sleeved on the outside of the slide rod 11.

[0027] When stones are fed in, the stones crushed by the first set of crushing rollers 2 fall onto the U-shaped screen plate 13, generating a downward force. Because the spring 12, which is fixedly connected between the lower surface of the U-shaped screen plate 13 and the upper surface of the fixed plate 10, and the sliding rod 11, which is movably connected inside the U-shaped screen plate 13, the U-shaped screen plate 13 is driven to move vertically up and down, accelerating the falling of the fully crushed stones through the holes on the surface of the U-shaped screen plate 13. The sliding rod 11 is located inside the spring 12 to prevent the spring 12 from deforming due to prolonged use.

[0028] Among them, the upper left surface of the U-shaped screen plate 13 is provided with a toggle structure, which includes a rotating shaft 14 rotatably connected to the left wall of the waste crushing box 1. A cam 15 is fixedly connected to one end of the rotating shaft 14 located inside the waste crushing box 1, and a belt 16 is connected between the other end of the rotating shaft 14 located outside the waste crushing box 1 and the auger 6.

[0029] This application applies an additional downward force to the U-shaped screen plate 13 through a toggle structure. Specifically, the output shaft of the first motor 5 is fixedly connected to the auger 6, and the auger 6 is connected to the rotating shaft 14 by a belt 16, thereby driving the rotating shaft 14 to rotate inside the waste crushing box 1. The rotation of the rotating shaft 14 drives the cam 15 to rotate, thereby toggle the surface of the U-shaped screen plate 13 through the cam 15, which can realize the up and down vibration of the U-shaped screen plate 13. The linkage between the first motor 5 and the rotating shaft 14 can also reduce the cost of using a servo motor.

[0030] By vibrating the U-shaped screen plate 13 up and down, stones larger than the aperture of the U-shaped screen plate will not linger at the aperture, thus affecting the screening efficiency. When stones that are not fully crushed fall to the lower upper surface of the U-shaped screen plate, due to the presence of the aperture, the stones will wear down the aperture of the U-shaped screen plate when the auger drives the stones to move to the right. The vibration of the U-shaped screen plate can shake the stones and extend the service life of the U-shaped screen plate.

[0031] The drive structure includes a support plate 17 fixedly connected to the rear side of the waste crushing box 1. A second motor 18 is fixedly installed on the upper surface of the support plate 17. The output shaft of the second motor 18 is fixedly connected to the rear end of the first set of crushing rollers 2. The output shaft of the second motor 18 is also connected to the rear end of the second set of crushing rollers 9 through a belt group 19.

[0032] The second motor 18 is supported by the support plate 17. Since the rear shafts of the first set of crushing rollers 2 and the second set of crushing rollers 9 pass through the rear wall of the waste crushing box 1, the second motor 18 is fixedly connected to the first set of crushing rollers 2. At the same time, the output shaft of the second motor 18 is connected to the first set of crushing rollers 2 through the transmission of the belt group 19, thereby realizing the synchronous rotation of the first set of crushing rollers 2 and the second set of crushing rollers 9.

[0033] The waste crushing box 1 has a first guide plate 20 fixedly connected to the left inner wall and the left surface of the first partition 3, located above the first set of crushing rollers 2. The waste crushing box 1 has a second guide plate 21 fixedly connected to the bottom of the inner wall. The waste crushing box 1 has a small stone discharge port 29 on the right side.

[0034] The design of the first guide plate 20 allows the stones to be fed into the space between the first set of crushing rollers 2, preventing the stones from passing through the space between the first set of crushing rollers 2 and the inner wall of the waste crushing box 1. The design of the second guide plate 21 allows the stones falling from the lower surface of the U-shaped screen plate 13 and the stones crushed by the second set of crushing rollers 9 to be discharged from the small stone discharge port 29 under the action of gravity.

[0035] The second partition 4 has a dust suction hole 22 at its upper part. A dust discharge placement plate 23 is fixedly connected to the right side of the second partition 4. A vacuum cleaner 24 is fixedly connected to the upper surface of the dust discharge placement plate 23. A fixed support plate 25 located below the dust discharge placement plate 23 is fixedly connected to the right side of the second partition 4. A collection box 26 is movably connected to the upper surface of the fixed support plate 25.

[0036] The dust inside the waste and gravel bin 1 is sucked into the vacuum cleaner 24 through the suction hole 22 by the vacuum cleaner 24. After the dust is processed inside the vacuum cleaner 24, it falls into the collection box 26 through the dust discharge plate 23. The staff can pull the collection box 26 to the right to detach it from the upper surface of the fixed support plate 25 to process the dust.

[0037] Among them, a support push plate 27 is fixedly connected to the lower surface of the waste crushing box 1, and a wheel 28 is fixedly connected to the lower surface of the support push plate 27.

[0038] By using the support plate 27 in conjunction with the wheels 28, the entire device can be moved, giving it good mobility and facilitating construction.

[0039] Working principle and usage process of this utility model:

[0040] When it is necessary to crush waste stones, the stones are fed into the feed inlet at the top left of the waste crushing box 1. The stones undergo the first round of crushing under the action of the first set of crushing rollers 2, and the stones are divided into two parts: the first part is fully crushed stones, and the second part is insufficiently crushed stones. Both parts of the stones fall onto the surface of the U-shaped screen plate 13. Due to the design of the U-shaped screen plate 13, the stones falling from both ends slide down the upper surface of the U-shaped screen plate 13, thus fully crushing the stones. The crushed stones will fall through the holes on the surface of the U-shaped screen plate 13 to the upper surface of the second guide plate 21 and be collected at the small stone outlet 29. The stones that are not fully crushed will fall to the lower upper surface of the U-shaped screen plate 13. At the same time, the first motor 5 is started when the stone is fed in. The operation of the first motor 5 drives the auger 6 to rotate, thereby pushing the insufficiently crushed stones to the large stone outlet 7. Under the action of the discharge tray 8, they are sent to the second set of crushing rollers 9 for the second round of crushing.

[0041] When the stone is put in, the first motor 5 is started, and the output shaft of the first motor 5 is connected to the rotating shaft 14 via the auger 6 and the belt 16, which drives the actuation structure to apply downward pressure to the U-shaped screen plate 13. The spring 12, which is fixedly connected between the lower surface of the U-shaped screen plate 13 and the upper surface of the fixed plate 10, and the slide rod 11, which is movably connected to the inside of the U-shaped screen plate 13, drive the U-shaped screen plate 13 to move vertically up and down.

[0042] A belt 16 is connected between the output shaft of the first motor 5 and the rotating shaft 14, thereby driving the rotating shaft 14 to rotate inside the waste crushing box 1, thereby driving the rotation of the cam 15, which in turn moves the surface of the U-shaped screen plate 13, thus achieving vibration of the U-shaped screen plate 13. The linkage between the first motor 5 and the rotating shaft 14 can reduce the cost of using a servo motor.

[0043] The second motor 18 is supported by the support plate 17. Since the rear shafts of the first set of crushing rollers 2 and the second set of crushing rollers 9 pass through the rear wall of the waste crushing box 1, the second motor 18 is fixedly connected to the first set of crushing rollers 2. At the same time, the output shaft of the second motor 18 is connected to the second set of crushing rollers 9 through the transmission of the belt group 19, thereby realizing the synchronous rotation of the first set of crushing rollers 2 and the second set of crushing rollers 9.

[0044] The design of the first guide plate 20 allows the stones to be fed into the space between the first set of crushing rollers 2, preventing the stones from passing between the first set of crushing rollers 2 and the waste crushing box 1. The design of the second guide plate 21 allows the stones falling from the lower surface of the U-shaped screen plate 13 and the stones crushed by the second set of crushing rollers 9 to be sent out of the equipment from the small stone discharge port 29 under the action of gravity.

[0045] The dust inside the waste and gravel bin 1 is sucked into the vacuum cleaner 24 through the suction hole 22 by the vacuum cleaner 24. After the dust is processed inside the vacuum cleaner 24, it falls into the collection box 26 through the dust discharge plate 23. The staff can pull the collection box 26 to the right to detach it from the upper surface of the fixed support plate 25 to process the dust.

[0046] By using the support plate 27 in conjunction with the wheels 28, the entire device can be moved, giving it good mobility and facilitating construction.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
