Description

Technical Field

[0002] The protective device is a device that uses a shielding method to isolate the human body from production hazards. The dangerous parts in production include the running parts of the machine equipment that may be touched during operation, the places where the debris of the processed materials may fly out, the live parts, high-temperature parts and radiant heat zones on the machine equipment that are easily touched, and the places in the factory yard and workplace that may cause falls and injuries. The protective device is created based on the principle of isolating dangerous factors, and plays an important role in preventing the occurrence of casualties. In the design, manufacture, installation, acceptance and use of the machine equipment, the necessary safety devices should be considered at the same time. The existing crusher has poor dust removal effect during use, which is easy to cause workers to inhale dust and cause harm to the body.

[0029] As shown in the figure, a base 1 is provided to support the whole and play a stabilizing role, and a shockproof structure can be provided in the base 1 to prevent the crusher from vibrating too much, causing the machine to age too quickly and generating too much noise from the vibration. A protective shell 2 is provided to protect the internal structure and prevent the mechanical structure from being exposed to the outside and causing harm to the staff who touch it accidentally. Two relatively rotating crushing rollers 5 are provided to crush the materials. A feeding assembly is provided to assist in unloading the materials and prevent the materials from accumulating and blocking the feed port and causing the baffle plate 16 to fail to close normally and cause the materials to splash out of the machine. The baffle plate 16 can close the feed port in time to prevent the crushed materials from splashing from the inside to the outside and causing harm to the workers. A unloading hopper 7 is provided to facilitate centralized unloading after crushing. A screening hopper 8 and a screen 9 can screen the materials and use vibration to prevent the materials from splashing out of the machine. The crushed materials are now piled up and are discharged from the inside in time to avoid the need for cleaning later. A dust removal box 10, a dust suction pipe 11, a filter 12, a knocking component, a driving component and a swinging component are set. The driving component can use the swinging component to drive the dust suction pipe 11 to swing, thereby expanding the dust suction range and improving the dust suction effect. At the same time, the driving component can knock on the two filters 12 through the knocking component, thereby removing the dust on the filter 12, thereby improving the use efficiency of the filter 12, and reducing the number of replacements, thereby reducing the time and number of manual operations, and reducing the occurrence of accidents.

A feeding port is opened on the upper side of the left end of the protective shell 2, and a blocking plate 16 that can block the feeding port is rotatably connected in the protective shell 2. A lever 17 is fixedly connected to the front end of the blocking plate 16, and an L-shaped push rod 18 is slidably connected to the front end of the protective shell 2. A return spring located between the lever 17 and the protective shell 2 is sleeved on the push rod 18, and the lever 17 can contact the left end of the push rod 18.

[0031] As shown in the figure, the provision of a feed plate, a conveyor belt 13, a rotating shaft 14, an anti-sliding block and a rejecting rake 15 can utilize the conveyor belt 13 to speed up the delivery of materials, avoid material blockage at the feed port, and prevent materials from getting stuck in the blocking plate 16, causing the blocking plate 16 to be unable to be lowered normally. The anti-sliding block can prevent the problem of materials being unable to roll on the conveyor belt 13 through the blocking plate 16 after contacting the blocking plate 16, thereby assisting in feeding, avoiding accumulation and being blocked by the blocking plate 16 from being unable to enter normally. The rejecting rake 15 can prevent smaller materials from being stuck in the gap between the anti-sliding blocks, causing the anti-sliding block to lose its function. The setting of the blocking plate 16 can prevent materials from splashing out of the feed port and causing harm to workers. The setting of the lever 17, the push rod 18 and the return spring facilitate the blocking plate 16 to rebound in time after the material passes through to block the feed port.

[0050] When the present invention is in use, the rotating motor 19 is started, and the rotating motor 19 drives the conveyor belt 13 and the crushing roller 5 to rotate, and at the same time drives the screening bucket 8 to start vibrating screening through the pull rod 31, and then the material is put into the inside from the feed port. The feeding component can assist the feeding to avoid the problem of blockage. At the same time, the blocking plate 16 can prevent the problem of collapse and splashing. The material enters the collecting hopper 6 from the conveyor belt 13, and then is crushed by the crushing roller 5. The crushed material enters the lower hopper 7, and then falls into the screening bucket 8 for screening. After screening, it is transported and processed separately. In the process of material falling, the dust suction pipe 11 absorbs dust, and the driving motor drives the dust suction pipe 11 to swing through the swing component, so as to achieve the effect of expanding the dust suction; After the dust removal box 10 has been used for a certain period of time, the internal filter 12 needs to be cleaned. At this time, the hydraulic rod 41 is started to drive the movable frame 42 to rise. At this time, the end spline can contact the contact rod 48, and the prism on the lower side of the lifting rod 39 is separated from the prism tube of the turntable 43.

Then, the drive motor is started, and the drive motor can be used to knock the filter 12 through the knocking assembly. The dust on the filter 12 enters the dust collection box 61 for unified treatment. After cleaning is completed, the hydraulic rod 41 can be used to drive the sleeve rod 40 and the lifting rod 39 to descend and connect with the turntable 43 to continue dust collection.

[0051] When it is necessary to repair the inside of the crushing roller 5, the hydraulic cylinder 62 is started, and the hydraulic cylinder 62 can push the movable shell 4 and the structure above it out of the protective shell 2. The maintenance door 64 is opened by the connecting rod 63, and the movable shell 65 is opened at the same time, so that the staff can repair the inside. When the movable shell 4 moves to the right, the swing rod 30 swings, and the adjustment pulley 25 moves to the left, thereby ensuring that the belt 26 is in a tight state, ensuring that it can be used normally during maintenance and testing; After the maintenance is completed, the movable shell 65 is closed, and then the hydraulic cylinder 62 can be used to drive the movable shell 4 to enter the protective shell 2. When the maintenance door 64 is completely closed, the housing can continue to be used and the reset is completed.
