Description

Technical Field

[0001] This utility model relates to the field of single-shaft shredder technology, specifically a material propulsion device for a single-shaft shredder. Background Technology

[0002] Roller shredders are machines that use the friction of the roller surface to bite materials into the crushing zone, causing them to be crushed by compression or splitting. When used for coarse crushing or when a larger crushing ratio is required, teeth or grooves are often made on the roller surface to increase the splitting effect. Roller shredders are usually classified into single-roller, double-roller, and multi-roller shredders according to the number of rollers. They are suitable for various materials such as plastics, wood, machine head material, braided material, sheet metal tubes, tires, aluminum alloys, and frozen meat.

[0003] The main components of a single-shaft shredder's material feeding device include a pusher plate, a hydraulic / electric drive system, guide rods, an overload protection device, and a control system. During operation, the drive system is first started. The pusher plate, under driving force, pushes the material from the feed inlet into the shredding chamber, with the guide rods ensuring a stable feeding direction. During operation, the overload protection device monitors the load in real time and automatically stops the machine to prevent damage if material becomes stuck. The feeding speed needs to be adjusted according to the material characteristics. After feeding is complete, the drive system is shut down, residual material is cleaned, and the wear of components is checked to ensure smooth operation next time.

[0004] Existing propulsion devices often encounter multiple efficiency problems when processing slurry-like waste materials with a moisture content exceeding 40% during operation and material crushing, due to the adhesion of sticky substances. When materials with high moisture content enter the shredding chamber, the moisture and organic matter form a colloidal mixture that quickly adheres to the surface of the pusher plate, forming a wet material layer. This layer tends to accumulate and clump together, especially at the joint between the pusher plate and the chamber, leading to increased pushing resistance, increased hydraulic system pressure, and reduced pushing speed. The wet material forms a "bridging" structure between the feed inlet and the inner wall of the propulsion device. For example, sludge particles expand upon contact with water and accumulate into arched impurities, reducing the actual feed rate. Insufficient feed also increases the idling time of the shredder's main shaft, resulting in reduced production capacity. Utility Model Content

[0005] The purpose of this invention is to provide a material propulsion device for a single-shaft shredder, to solve the problem that existing propulsion devices often cause multiple efficiency issues due to the adhesion of sticky substances when processing slurry-like waste materials with a moisture content exceeding 40% during operation and material crushing. When materials with high moisture content enter the shredding chamber, the moisture and organic matter form a colloidal mixture, which quickly adheres to the surface of the pusher plate, forming a wet material layer. Especially at the joint between the pusher plate and the chamber, it is easy to accumulate and form clumps, leading to increased pushing resistance, increased hydraulic system pressure, and reduced pushing speed. The wet material forms a "bridging" structure between the feed inlet and the inner wall of the propulsion device. For example, sludge particles expand after encountering water and accumulate into arches, reducing the actual feed volume. The shredder main shaft also experiences increased idling time due to insufficient feed, resulting in reduced production capacity.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A material feeding device for a single-shaft shredder includes a housing, on which a sleeve is fixedly mounted:

[0008] The material pushing unit includes a servo motor fixedly mounted on the outer shell, a telescopic rod slidably mounted on the sleeve, a pressure plate fixedly mounted on one end of the telescopic rod, a turntable rotatably mounted on the other end of the telescopic rod, a material pushing rod slidably mounted on the outer shell, and a long plate fixedly mounted on the material pushing rod. The material pushing unit is used to push and crush the material placed in the single-shaft shredder.

[0009] The cleaning unit includes an inner shell fixedly disposed within the outer shell, a striking column slidably disposed within the inner shell, an impact head fixedly disposed at the end of the striking column, and a long plate fixedly disposed on the outer shell. The cleaning unit is used to vibrate and clean impurities adhering to the push plate.

[0010] Preferably, a disc is fixedly disposed on the outer circumferential surface of the telescopic rod, and a spring is fixedly disposed on the bottom of the disc, with the other end of the spring being fixedly connected to the outer shell.

[0011] Preferably, a bracket is fixedly mounted on the outer shell, and a frustum is rotatably mounted on the bracket, with the frustum fitting against the turntable.

[0012] Preferably, the surface of the frustum that is in contact with the turntable is perpendicular to the turntable, and an eccentric column is eccentrically provided on the turntable. A guide plate is fixedly provided on the end of the push rod, and a guide groove is provided on the guide plate. The eccentric column and the guide groove are slidably connected.

[0013] Preferably, the length of the eccentric column is not less than the vertical length of the frustum, and the diameter of the turntable is not greater than the length of the guide plate.

[0014] Preferably, an adjusting rod is fixedly provided on the outer wall of the push rod, and a sliding groove is provided on the outer peripheral surface of the inner shell, and the adjusting rod is slidably connected to the sliding groove.

[0015] Preferably, a second spring is fixedly installed inside the inner shell, the other end of the second spring is fixedly connected to the striking post, and a control groove is provided on the side wall of the striking post, and the adjusting rod is slidably connected to the control groove.

[0016] Preferably, the control groove is inclined downwards, and the height of the control groove is the same for different striking columns.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] When the operator adds material to the single-shaft crusher, the weight of the material presses down on the pressure plate of the device. At this time, the pressure plate controls the telescopic rod to move down and adjusts the contact surface between the turntable and the truncated pyramid, thereby controlling the rotational transmission rate of the truncated pyramid to the turntable. Furthermore, the rotating turntable and the eccentric column control the reciprocating extension and retraction of the push rod, allowing the push plate to reciprocate to push the material into the crusher for crushing. During the reciprocating movement of the push rod, the adjusting rod drives the striking column to move up and down, thereby striking the long plate and causing it to vibrate, which vibrates and knocks off impurities adhering to the push plate.

The other end of the spring 23 is fixedly connected to the outer shell 1. Through the spring 23 installed on the disc 22, when material is placed on the pressure plate 3, the pressure generated can press down the spring 23, thereby causing the telescopic rod 21 to extend and retract downward.

[0031] Reference Figures 1-2 A bracket 11 is fixedly installed on the outer shell 1, and a frustum 12 is rotatably installed on the bracket 11. The frustum 12 is in contact with the turntable 5. The position of the frustum 12 is fixed by the bracket 11 installed on the outer shell 1, so as to ensure the stability of the frustum 12.

[0032] Reference Figures 1-3 The surface of the frustum 12 that is in contact with the turntable 5 is perpendicular to the turntable 5, and an eccentric column 51 is eccentrically provided on the turntable 5. A guide plate 411 is fixedly provided on the end of the push rod 41. A guide groove is provided on the guide plate 411. The eccentric column 51 is slidably connected to the guide groove. Through the eccentric column 51 provided on the turntable 5, the eccentric column 51 can drive the guide plate 411 to move back and forth when the turntable 5 rotates. The moving guide plate 411 can control the movement of the push rod 41 fixedly connected to it.

[0033] Reference Figures 3-5 The length of the eccentric column 51 is not less than the vertical length of the frustum 12, and the diameter of the turntable 5 is not greater than the length of the guide plate 411. By setting the length relationship between the eccentric column 51 and the frustum 12, the device can be ensured to operate normally and stably.

[0034] Reference Figures 3-5An adjusting rod 412 is fixedly installed on the outer wall of the push rod 41, and a sliding groove 61 is opened on the outer peripheral surface of the inner shell 6.

The height of the control groove 72 of different striking columns 7 is the same. By setting the control groove 72 on the striking column 7, the movement of the striking column 7 can be controlled when the control rod 412 moves. When the control rod 412 is disengaged from the control groove 72, the elastic force generated by the second spring 71 can push the striking column 7 to strike the vibrating plate 42, thereby controlling the vibration of the pusher plate 4 and causing impurities to fall off.

[0036] Specifically, the solution is as follows: When the operator adds material to the single-shaft crusher, the weight of the material presses down on the pressure plate 3 of the device. When material is placed on the pressure plate 3, the pressure generated can press down the spring 23, thereby causing the telescopic rod 21 to extend and retract downwards. Then, the servo motor 40 is started, causing the frustum 12 on its output end to rotate. The rotating frustum 12 can drive the turntable 5 to rotate. When the turntable 5 rotates, the eccentric column 51 can drive the guide plate 411 to move back and forth. The moving guide plate 411 can control... The push rod 41, which is fixedly connected to it, moves. The regulating rod 412, which is set on the push rod 41, can move along the sliding groove 61 on the inner shell 6 when the regulating rod 412 moves. The control groove 72, which is set on the striking column 7, can control the movement of the striking column 7 when the regulating rod 412 moves. When the regulating rod 412 is disengaged from the control groove 72, the elastic force generated by the spring 71 can push the striking column 7 to strike the vibrating plate 42, thereby controlling the vibration of the push plate 4 and causing impurities to fall off.
