Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to an integrated device for crushing and screening solid waste. Background Technology

[0002] Solid waste crushing is a key pre-processing step in the resource recycling chain. Its core purpose is to reduce the size of materials and destroy their structure by applying external forces (impact, shearing, extrusion, etc.) to facilitate subsequent processing and transportation. Current crushing devices generally have a rotating structure inside the crushing chamber, with hammers on the rotating structure and impact plates on the inner wall of the crushing chamber. The materials are crushed by the action of the hammers and impact plates. However, since the hammers are generally fixed on the rotating structure, the action of the hammers and impact plates is singular, resulting in insufficient material crushing and a long time consumption. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an integrated solid waste crushing and screening device that effectively improves crushing efficiency by optimizing the action of the hammer and the impact plate.

[0004] According to an embodiment of this utility model, an integrated solid waste crushing and screening device includes a crushing box and a screening box disposed below the crushing box. The crushing box has a cylindrical cavity and is rotatably connected to a cylindrical transmission seat. One end of the transmission seat is connected to a power mechanism. Multiple sets of hammer assemblies that can move radially are movably disposed on the side of the transmission seat. The same set of hammer assemblies is evenly distributed along the axial direction of the transmission seat. The transmission seat is also provided with a reciprocating drive mechanism that is connected to the hammer assemblies. The inner wall of the cavity is provided with impact plates located on both sides of the transmission seat. The crushing box is connected to the screening box through a buffer connection mechanism.

[0005] Preferably, the transmission seat has a transmission cavity, and the side of the transmission seat has multiple sets of guide holes communicating with the transmission cavity along the radial direction. The reciprocating drive mechanism includes multiple sets of crankshaft transmission components disposed in the transmission cavity and power components disposed at the end of the transmission seat. The hammer assembly passes through the guide holes and is connected to the crankshaft transmission components for transmission.

[0006] More preferably, each crankshaft transmission assembly includes multiple coaxially arranged main shafts parallel to the axis of the transmission seat, cranks connected between the main shafts, and transmission rods rotatably connected to the cranks and the crankshaft transmission assembly. The main shafts are connected to the power assembly in a transmission connection.

[0007] More preferably, each of the main shafts is rotatably connected to a stabilizer fixed to the transmission cavity.

[0008] More preferably, the plurality of cranks are respectively disposed at different positions on the side of the axis of the main shaft.

[0009] More preferably, both ends of the transmission seat pass through the crushing box and are rotatably connected thereto. The power assembly includes a drive wheel rotatably mounted at the end of the transmission seat and a power motor fixed at the end of the transmission seat by a bracket. The power motor is drively connected to the drive wheel. One end of each main shaft passes through the outside of the transmission seat and is coaxially connected to a driven wheel connected to the drive wheel by a belt.

[0010] More preferably, the hammer assembly includes a guide seat that slides with the guide hole and a hammer body that is detachably connected to the guide seat.

[0011] More preferably, the buffer connection mechanism includes a discharge pipe disposed at the bottom of the crushing box, the discharge pipe extending into the screening box and connected thereto by an elastic coupling member.

[0012] In a further preferred embodiment, the screening box is provided with three layers of composite screens with different inclination angles, the inclination angles of the three layers of the composite screens being 30°, 15° and 0° from top to bottom, respectively, and the sieve aperture of the composite screens gradually decreasing from top to bottom.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] A rotatable transmission seat is installed inside the crushing chamber. A hammer assembly that can move radially is installed on the transmission seat. The transmission seat has a transmission cavity, and a reciprocating drive mechanism that is connected to the hammer assembly is installed inside the transmission cavity. During the process of the transmission seat driving the hammer assembly to rotate, the hammer assembly generates a small-amplitude reciprocating motion under the action of the reciprocating drive mechanism. The combination of the reciprocating motion of the hammer assembly itself and the rotational motion with the transmission seat can effectively improve the crushing effect between the hammer assembly and the impact plate and accelerate the crushing work.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, this embodiment provides an integrated solid waste crushing and screening device, including a crushing box 1 and a screening box 2 disposed below the crushing box 1. The bottom of the screening box 2 is provided with a base, and the screening box 2 is connected to the base through an elastic element. A vibration generator is provided on the screening box 2. Vertical support legs are fixedly connected to the side of the crushing box 1. The crushing box 1 is provided with a cylindrical cavity 101 and a cylindrical transmission seat 3 is rotatably connected to it. The axis of the cavity 101 is horizontal. The transmission seat 3 is coaxially arranged with the cavity 101. One end of the transmission seat 3 is connected to a power mechanism, and the power mechanism drives the transmission seat 3 to rotate.

[0022] The transmission seat 3 is movably provided with multiple sets of hammer head assemblies 310 that can move radially along its side. The multiple sets of hammer head assemblies 310 are evenly distributed around the circumference of the transmission seat 3. Multiple hammer head assemblies 310 in the same set are evenly distributed along the axial direction of the transmission seat 3. The transmission seat 3 is also provided with a reciprocating drive mechanism 4 that is connected to the hammer head assembly 310. The reciprocating drive mechanism 4 drives the hammer head assembly 310 to generate a small reciprocating motion. The inner wall of the cavity 101 is provided with impact plates 102 located on both sides of the transmission seat 3. The crushing box 1 is connected to the screening box 2 through a buffer connection mechanism 5.

[0023] When the hammer assembly 310 produces a small-amplitude reciprocating motion, it can create a crushing effect on the material by clamping with the impact plate 102. Accompanied by the rotation of the transmission seat 3, it can produce a variety of crushing effects, thereby effectively improving the crushing efficiency of the material.

[0024] To achieve the reciprocating motion of the hammer assembly 310, such as Figure 2As shown, the transmission seat 3 has a transmission cavity 301 inside. The transmission cavity 301 is cylindrical and coaxially arranged with the transmission seat 3. The side of the transmission seat 3 has multiple sets of guide holes 302 that communicate with the transmission cavity 301 along the radial direction. The multiple sets of guide holes 302 correspond one-to-one with multiple sets of hammer assemblies 310. The reciprocating drive mechanism 4 includes multiple sets of crankshaft transmission assemblies 410 arranged in the transmission cavity 301 and corresponding one-to-one with the multiple sets of guide holes 302, and a power assembly 420 arranged at the end of the transmission seat 3. The power assembly 420 drives the crankshaft transmission assembly 410 to rotate. The hammer assembly 310 passes through the guide holes 302 and is connected to the crankshaft transmission assembly 410 for transmission. The crankshaft transmission assembly 410 drives the hammer assembly 310 to reciprocate.

[0025] Specifically, such as Figure 2 As shown, each crankshaft transmission assembly 410 includes multiple coaxially arranged main shafts 411 parallel to the axis of the transmission seat 3, cranks 412 connected between the main shafts 411, and transmission rods 413 rotatably connected to the cranks 412 and the crankshaft transmission assembly 410. The main shafts 411 are connected to the power assembly 420 in a transmission connection.

[0026] In order to improve the stability of the crankshaft drive assembly 410 during rotation, in a further embodiment, each of the main shafts 411 is rotatably connected to a stabilizer 414 fixed to the drive cavity 301.

[0027] In order to achieve different clamping effects from different hammer assemblies 310 and improve the crushing effect, in a further embodiment, such as Figure 4 As shown, the plurality of cranks 412 are respectively disposed at different positions on the side of the axis of the main shaft 411.

[0028] In order to synchronously drive the rotation of multiple crankshaft drive assemblies 410, in a further embodiment, such as Figure 3 As shown, both ends of the transmission seat 3 pass through the crushing box 1 and are rotatably connected to it. One end of the transmission seat 3 is connected to the power mechanism, and the other end is provided with a power assembly 420. The power assembly 420 includes a drive wheel 421 rotatably mounted at the end of the transmission seat 3 and a power motor fixed at the end of the transmission seat 3 by a bracket. The power motor is connected to the drive wheel 421. One end of each main shaft 411 passes through the outside of the transmission seat 3 and is coaxially connected to a driven wheel 422 connected to the drive wheel 421 by a belt.

[0029] To facilitate replacement of the worn hammer assembly 310, in a further embodiment, such as Figure 1 As shown, the hammer assembly 310 includes a guide seat 311 that slides with the guide hole 302 and a hammer body 312 that is detachably connected to the guide seat 311.

[0030] Specifically, such as Figure 1 As shown, the buffer connection mechanism 5 includes a discharge pipe 501 disposed at the bottom of the crushing box 1. The discharge pipe 501 extends into the screening box 2 and is connected to it through an elastic coupling member 502. In this embodiment, the elastic coupling member 502 includes a corrugated hose connecting the side of the discharge pipe 501 to the top wall of the screening box 2.

[0031] To improve screening efficiency, in a further implementation, such as Figure 1 As shown, the screening box 2 is equipped with a composite screen 201 with three layers of different inclination angles. The inclination angles of the three layers of the composite screen 201 are 30°, 15° and 0° from top to bottom, respectively, and the sieve hole diameter of the composite screen 201 gradually decreases from top to bottom.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
