Description

Technical Field

[0001] The utility model belongs to the technical field of crushed stone processing, in particular to a feeding and conveying device for crushing and processing crushed stone. Background Art

[0002] Gravel is a building material that can be used in construction projects such as road paving and concrete processing. Currently, a loading and conveying device is required in the gravel processing process to transport large-particle gravel to the crusher for crushing and crushing the gravel into specified specifications.

[0003] The existing feeding and conveying device for gravel crushing is usually a belt conveyor, which is composed of a power roller assembly, a frame, a belt and other components. The electric roller and the belt are used to transport the gravel to the feed port of the crusher. It has the advantages of large conveying capacity, easy maintenance and simple structure. However, the current feeding and conveying device for gravel crushing does not have a belt self-cleaning function. Due to the irregular shape of the gravel, some small gravel has sharp corners. During the transportation process, it is easy to be embedded in the belt after being pressed by the upper layer of gravel. If it is not cleaned in time, the surface of the belt will be damaged after multiple cycles of transportation, which shortens the service life of the belt. For this reason, we provide a feeding and conveying device for gravel crushing to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a feeding and conveying device for crushed stone processing. By coordinating the belt cleaning component and the vibration component, the utility model solves the problem that the feeding and conveying device for crushed stone processing in the prior art has no belt self-cleaning function. In the process of conveying and feeding the crushed stone, some small crushed stones have sharp corners, which are easily embedded in the belt after being pressed by the upper layer of crushed stones during the conveying process. Long-term use will cause the belt to break, thereby reducing the service life of the belt.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a feeding and conveying device for crushing stone, comprising a frame, a belt cleaning assembly and a vibration assembly. Both sides between the front and rear sides of the inner cavity of the frame are fixedly connected to electric rollers, and a belt guide frame is fixedly connected between the front and rear sides of the inner cavity of the frame.

[0007] The belt cleaning assembly is arranged on the right side of the bottom of the frame, including a mounting plate, the bottom of the mounting plate is fixedly connected to a control box, the left side of the inner cavity of the control box is fixedly connected to a drive motor, the right side of the output end of the drive motor is fixedly connected to a screw, the surface of the screw is threadedly connected to a telescopic rod, the right side of the telescopic rod passes through the control box and is fixedly connected to a fixing frame, the front side of the inner cavity of the fixing frame is fixedly connected to a rotating motor, and the rear side of the output end of the rotating motor is fixedly connected to a cleaning roller;

[0008] The vibration assembly is arranged on the right side of the inner cavity of the frame, and includes a vibration shell. The inner cavity of the vibration shell is provided with a movable plate. The top of the movable plate is fixedly connected to a vibrator. A spring is fixedly connected between the top of the movable plate and the inner wall of the vibration shell. The bottom of the movable plate is fixedly connected to a vibrating head.

[0009] The present invention is further configured such that both sides of the bottom of the frame are fixedly connected with support frames, and the bottom of the support frames is fixedly connected with moving wheels.

[0010] The utility model is further configured such that a material guide rack is fixedly connected to the left side of the top of the frame, and guide plates are fixedly connected to the front and rear sides of the inner cavity of the material guide rack.

[0011] The utility model is further configured such that the front and rear sides of the bottom of the mounting plate are fixedly connected with sliding sleeves, the inner cavity of the sliding sleeves is slidably connected with a sliding rod, and the right side of the sliding rod is fixedly connected to the fixing frame.

[0012] The utility model is further configured such that the rear side of the cleaning roller is movably connected to the inner wall of the fixing frame via a bearing, and a rubber scraper is fixedly connected to the surface of the cleaning roller.

[0013] The utility model is further configured such that the number of the springs is four and they are evenly distributed on the top of the movable plate, and the bottom of the vibrating head is in contact with the belt.

[0014] The utility model is further configured such that a slide groove is provided on the front and rear sides of the movable plate, a slide bar is slidably connected to the inner cavity of the slide groove, and a side of the slide bar away from the movable plate is fixedly connected to the inner wall of the vibration shell.

[0015] The utility model is further configured such that a movable hole for use with a telescopic rod is provided on the right side of the control box, and the frame is tilted.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model is provided with a belt cleaning assembly, and the cleaning roller can be controlled to rotate by a rotating motor, while the rubber scraper fixed on the surface of the cleaning roller contacts the bottom of the belt. The rotation direction of the cleaning roller is opposite to that of the belt. When gravel is embedded in the belt, the counter-rotating cleaning roller uses the friction between the rubber scraper and the gravel to pull it out of the belt. At the same time, the driving motor cooperates with the screw to control the telescopic rod and the fixed frame to move back and forth left and right, thereby improving its cleaning effect, preventing sharp gravel from being embedded in the belt for a long time, and increasing the service life of the belt.

[0018] 2. The utility model can make the vibrating head contact with the belt through the setting of the vibration component, and use the spring to make the vibrating head press against the belt. During the process of gravel feeding, the vibrator is turned on, and the movable plate and the vibrating head are driven to vibrate by the vibrator. At the same time, the vibration is transmitted to the belt, so that the gravel attached to the surface of the belt is shaken off, thereby further improving the cleaning effect of the belt and extending the service life of the belt.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When gravel is embedded in the belt, it rotates in the opposite direction. The cleaning roller 408 uses the friction between the rubber scraper and the gravel to pull it out of the belt, and at the same time drives the motor 403 and the screw 404 to control the telescopic rod 405 and the fixed frame 406 to move back and forth left and right, thereby improving its cleaning effect, avoiding sharp gravel from being embedded in the belt for a long time, and increasing the service life of the belt. At the same time, the vibrator 503 is turned on, and the movable plate 502 and the vibrating head 505 are driven by the vibrator 503 to vibrate, and the vibration is transmitted to the belt, so that the gravel attached to the surface of the belt is shaken off, further improving the cleaning effect of the belt and extending the service life of the belt.
