Description

Technical Field

[0001] The present invention relates to the technical field of construction waste recycling, and specifically to a construction waste hammer crusher. Background Art

[0002] In the field of construction waste treatment, as a key equipment, the performance of the crusher is directly related to the treatment efficiency and recycling value of construction waste. Traditional construction waste crushers mostly adopt simple hammering or shearing methods. Although they can achieve basic crushing functions, in actual use, the problem of screen plate blockage often occurs. As an important component of the crusher, the main function of the screen plate is to screen the crushed construction waste to ensure that only the construction waste meeting the particle size requirements can pass through and be conveyed to the next process for further treatment. However, due to the complex composition of construction waste, including large pieces of materials, fibrous materials, and fine particles in various forms, these materials are prone to accumulate on the screen plate during the crushing process, forming blockages, resulting in a decrease in crushing efficiency and even affecting the stable operation of the entire crusher.

[0003] To solve the problem of screen plate blockage, the traditional method often requires operators to stop the machine regularly for dredging. This not only increases labor costs and operation complexity but also reduces the continuous operation ability of the crusher. In addition, frequent shutdown for dredging will also have a certain impact on the service life of the crusher and increase equipment maintenance costs. Therefore, a construction waste hammer crusher is needed. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a construction waste hammer crusher, which solves the problem that the screen plate in the traditional method is easily blocked by large pieces of construction waste, affecting the crushing efficiency of construction waste, and requires operators to often dredge it to ensure the stable operation of the equipment.

[0005] To achieve the above object, the present invention provides the following technical solution: A construction waste hammer crusher includes a crushing chamber body, and a crushing and blockage clearing assembly is arranged on the crushing chamber body for blockage clearing. The crushing and blockage clearing assembly includes a discharge chamber body, a hammer crushing roller, a screen plate stopper, a screen plate, a gear, a disk, a connecting rod, a guide plate fixing block, a C-shaped connecting frame, a servo push rod, a rack, and a chute rail; The discharge chamber body in the crushing and blockage clearing assembly is fixedly connected below the crushing chamber body, and a conveyor belt assembly is fixedly connected below the discharge chamber body. The hammer crushing roller rotates in the crushing chamber body, and a plurality of crushing hammers are rotatably connected to the hammer crushing roller; An outlet groove is formed on the lower surface of the crushing chamber body, and two screen plate stoppers are respectively fixedly connected to both sides of the outlet groove on the crushing chamber body. The screen plate is movably installed in the space between the outlet groove and the two screen plate stoppers.

[0006] Preferably, a plurality of screening grooves are formed on the outer surface of the sieve plate, and the plurality of screening grooves are evenly distributed at equal intervals. One side of the conveyor belt assembly is fixedly connected with a support frame, and both of the chute rails are fixedly connected to the support frame, and sliders are slidably connected in the chute rails respectively.

[0007] Preferably, on the opposite surfaces of the two sliders, fixing plates are fixedly connected respectively, and gear shafts are rotatably connected to the fixing plates respectively.

[0008] Preferably, the guide plate fixing block is rotatably connected between the two fixing plates, and a plurality of guide plates adapted to the screening grooves are fixedly connected to the guide plate fixing block.

[0009] Preferably, the two gears are respectively fixedly sleeved on the outer surfaces of the corresponding gear shafts, and the two racks are respectively fixedly connected to the upper surfaces of the corresponding chute rails.

[0010] Preferably, the two gears are respectively meshed with the corresponding racks, and the two discs are respectively fixedly sleeved on the opposite ends of the two gear shafts.

[0011] Preferably, two connecting rods are fixedly connected to the guide plate fixing block, and the two connecting rods are respectively rotatably connected to the corresponding connecting rods.

[0012] Preferably, the ends of the connecting rods far away from the connecting rods are respectively rotatably connected to the edge positions of the discs.

[0013] Preferably, a push rod fixing plate is fixedly connected between the two chute rails, and a servo push rod is fixedly installed on the push rod fixing plate.

[0014] Preferably, the output end of the servo push rod is fixedly connected with a C-shaped connecting frame, and a power assembly for driving the hammer-type crushing roller to operate is fixedly installed on the crushing chamber body.

[0015] Compared with the prior art, the present invention provides a construction waste hammer crusher, which has the following beneficial effects: In this construction waste hammer crusher, through the reciprocating swing of the guide plate and its movement towards the position close to the screening groove, the large pieces of construction waste blocked in the screening groove can be cleaned, so that the blocked construction waste can be bounced back into the working area of the hammer-type crushing roller in the crushing chamber body and be broken into qualified particle sizes again. This enables the crushing work of construction waste to be carried out stably and effectively, avoiding the problem that in the traditional method, the sieve plate is easily blocked by large pieces of construction waste, affecting the crushing efficiency of construction waste, and requiring operators to often dredge it to ensure the stable operation of the equipment.

[0016] The hammer crusher for construction waste has a guide plate whose motion form is continuous reciprocating swing. This enables the guide plate to continuously strike the blocked construction waste during its movement, allowing even severely blocked construction waste to be continuously struck and cleaned, which further improves the cleaning efficiency of the sieve trough.

[0017] The hammer crusher for construction waste effectively solves the problem of sieve trough blockage through a series of mechanical structures such as a servo push rod, C-shaped connecting frame, fixed plate, slider, gear, rack, gear shaft, disc, connecting rod, connecting rod, guide plate fixing block, and guide plate. When the sieve trough is blocked, the servo push rod can drive the guide plate to reciprocate and move towards the position close to the sieve trough. This motion form can continuously strike the blocked construction waste, enabling even severely blocked construction waste to be cleaned.

[0018] The hammer crusher for construction waste effectively avoids this problem through the design of automatically cleaning the sieve trough. When the sieve trough is blocked, the equipment can automatically clean it without manual intervention, thereby improving the automation degree and operating efficiency of the equipment.

[0019] For the hammer crusher for construction waste, the problem of sieve trough blockage has been effectively solved. Construction waste can pass through the sieve trough more smoothly and fall onto the conveyor belt assembly, and then be conveyed to the next process. In this way, the entire crushing process is smoother, and the crushing efficiency of construction waste is also improved. Description of the Drawings

The crushing and blockage clearing assembly includes a discharge chamber body 2, a hammer crushing roller 4, a screen plate stopper 5, a screen plate 7, a gear 12, a wheel disc 13, a connecting rod 14, a guide plate fixing block 15, a C-shaped connecting frame 17, a servo push rod 18, a rack 21, and a chute rail 24; The discharge chamber body 2 in the crushing and blockage clearing assembly is fixedly connected below the crushing chamber body 1, a conveyor belt assembly 3 is fixedly connected below the discharge chamber body 2, the hammer crushing roller 4 rotates in the crushing chamber body 1, and a plurality of crushing hammers are rotatably connected to the hammer crushing roller 4; An outlet groove 6 is opened on the lower surface of the crushing chamber body 1, and two screen plate stoppers 5 are respectively fixedly connected to both sides of the outlet groove 6 on the crushing chamber body 1. The screen plate 7 is movably installed in the space between the outlet groove 6 and the two screen plate stoppers 5.

[0027] Furthermore, a plurality of sieve grooves 8 are formed on the outer surface of the sieve plate 7, and the plurality of sieve grooves 8 are evenly distributed at equal intervals. One side of the conveyor belt assembly 3 is fixedly connected with a support frame 23, and two chute rails 24 are fixedly connected to the support frame 23. Sliders 9 are slidably connected within the chute rails 24.

[0028] Furthermore, on the opposite sides of the two sliders 9, fixing plates 10 are fixedly connected respectively, and gear shafts 11 are rotatably connected to the fixing plates 10.

[0029] Furthermore, a guide plate fixing block 15 is rotatably connected between the two fixing plates 10, and a plurality of guide plates 16 adapted to the sieve grooves 8 are fixedly connected to the guide plate fixing block 15.

[0030] Furthermore, two gears 12 are respectively fixedly sleeved on the outer surfaces of the corresponding gear shafts 11, and two racks 21 are respectively fixedly connected to the upper surfaces of the corresponding chute rails 24.

[0031] Furthermore, the two gears 12 are respectively meshed with the corresponding racks 21, and two discs 13 are respectively fixedly sleeved on the opposite ends of the two gear shafts 11.

[0032] Furthermore, two connecting rods 22 are fixedly connected to the guide plate fixing block 15, and two connecting rods 14 are respectively rotatably connected to the corresponding connecting rods 22.

[0033] Furthermore, the ends of the connecting rods 14 far from the connecting rods 22 are respectively rotatably connected to the edge positions of the discs 13.

[0034] Furthermore, a push rod fixing plate 19 is fixedly connected between the two chute rails 24, and a servo push rod 18 is fixedly installed on the push rod fixing plate 19.

[0035] Furthermore, the output end of the servo push rod 18 is fixedly connected to a C-shaped connecting frame 17, and a power assembly 20 for driving the hammer-type crushing roller 4 to operate is fixedly installed on the crushing chamber body 1.

[0036] Further, when in use, it is started by the provided power component 20, which can drive the hammer-type crushing roller 4 to operate. At this time, the construction waste to be crushed is poured into the crushing chamber 1. At this time, the construction waste in contact with the high-speed rotating hammer-type crushing roller 4 will be crushed. After the construction waste is crushed to a certain extent, it will fall onto the conveyor belt assembly 3 through the sieve slots 8 on the sieve plate 7. The conveyor belt assembly 3 can convey the crushed construction waste to the next process.

This enables the blocked construction waste to be bounced back into the working area of the hammer-type crushing roller 4 in the crushing chamber 1 and be crushed into qualified particle sizes again. This enables the crushing work of the construction waste to be carried out stably and effectively, avoiding the problem that the sieve plate in the traditional method is easily blocked by large pieces of construction waste, affecting the crushing efficiency of the construction waste, and requiring operators to often dredge it to ensure the stable operation of the equipment.

[0037] Further, by setting the movement form of the guide plate 16 to be continuous reciprocating swing, the guide plate 16 can continuously knock the blocked construction waste during the movement, so that some severely blocked construction waste can also be continuously knocked and cleaned, which can further improve the cleaning efficiency of the sieve slot 8.
