Description

Technical Field

[0001] The utility model belongs to the field of shredders, and specifically relates to an efficient shredder. Background Art

[0002] Shredders are generally used to process the crushing of unprocessed raw materials or scraps. During use, large shredders usually use a transportation mechanism to convey the materials to be shredded. Usually, a forklift and a conveyor belt are used in cooperation to convey the materials to be shredded.

[0003] A material conveyor belt device disclosed in Chinese Patent CN217534324U includes a conveyor belt and multiple groups of idler mechanisms. Among them, the conveyor belt is the main body for conveying materials, and the idler mechanism is used to tension the conveyor belt and drive the conveyor belt to move stably. Positioning strips with a V-shaped cross-section are respectively arranged on both sides of the top surface and the bottom surface of the conveyor belt, and the positioning strips extend along the length direction of the conveyor belt, that is, these positioning strips are arranged in parallel. The idler mechanism includes a lower idler and two upper idlers. First positioning grooves are respectively arranged at both ends of the circumferential side wall of the lower idler. The two upper idlers are arranged at both ends of the lower idler and have an interval space to form a gap for the conveyor belt to pass through. Second positioning grooves are arranged on the circumferential side wall of the upper idler, and the upper idler and the lower idler are meshed through gears to make the upper idler and the lower idler rotate synchronously. Multiple groups of idler mechanisms are distributed along the length direction of the conveyor belt. The conveyor belt is supported on the lower idler, and the positioning strips on both sides of the bottom surface of the conveyor belt cooperate with the first positioning grooves at both ends of the lower idler to position the conveyor belt in the width direction. The upper idler presses on both sides of the conveyor belt, and the positioning strips on both sides of the top surface of the conveyor belt cooperate with the second positioning grooves of the upper idler to position the conveyor belt in the width direction, and the conveyor belt is driven by the lower idler and the upper idler at the same time, which can effectively prevent the conveyor belt from being damaged due to wrinkles.

[0004] Due to the large height of large shredders, the existing conveyor belts need to be installed obliquely to convey materials to the shredder. However, some irregular materials will roll down when being conveyed upward, which is likely to cause danger. Summary of the Invention

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A high-efficiency shredder comprises a chassis, bearing rollers are symmetrically arranged in the chassis, a plurality of knife teeth are fixedly sleeved on the bearing rollers at equal intervals, a conveyor frame is integrally connected to the front surface of the chassis, a slide groove is centrally provided on the conveyor frame, auxiliary rollers are rotatably connected to both ends of the slide groove, a driving roller is provided below one of the auxiliary rollers close to the chassis, crawlers are sleeved on the auxiliary rollers and the driving roller, a transport mechanism is slidably connected to the upper surface of the conveyor frame, and the lower surface of the transport mechanism is fixedly connected to the crawler belt, materials are placed in the transport mechanism, and the crawler belt is driven by the driving roller to move obliquely upward close to the chassis port, and the transport mechanism dumps the materials into the chassis and shreds them through the knife teeth.

[0007] The transport mechanism comprises a slide and a loading box hinged on the upper surface of the slide, a convex block is integrally connected in the center of the lower surface of the slide, and the convex block extends into the slide groove and is fixedly connected to the crawler track.

[0008] Connecting ears are provided at both ends of one side of the upper surface of the slide, and the side faces of the loading box are hinged to the connecting ears. Support blocks are provided at both ends of the other side of the upper surface of the slide, and the loading box is lifted and kept horizontal by the support blocks.

[0009] The connecting ears and the support blocks are used to keep a certain distance between the lower surface of the loading box and the upper surface of the slide. A cylinder is pinned on the upper surface of the slide, and the output end of the cylinder is pinned to the lower surface of the loading box. The cylinder is placed at an angle and moves toward the support block when working.

[0010] A slider is stacked on the side of the lower surface of the slide that contacts the conveyor frame, and a slide groove is symmetrically arranged on the upper surface of the slide to be slidably connected to the slider. A supporting foot is symmetrically arranged on the other side of the lower surface of the slide, and a notch is cut at the bottom of the supporting foot. A roller is installed in the notch, and the roller contacts the conveyor frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] This application improves the drawback that when a large shredder uses a crawler conveyor mechanism, the need for inclined installation will cause materials to roll over from the crawler conveyor mechanism, resulting in danger. Specifically, a loading box is installed on the crawler, and the loading box is used to convey materials, so that the crawler changes from a conveyor to a power source. The loading box, as a component for holding materials, remains horizontal on the crawler, so that the materials can be safely conveyed into the shredder.

[0015] Furthermore, since the crawler serving as the power source is inclinedly installed, and the loading box installed on the crawler needs to remain horizontal, this application is provided with a sliding frame between the loading box and the crawler. The upper end of the sliding frame is a plate-shaped member, so that the loading box is installed thereon to remain horizontal. The lower end of the sliding frame is a triangular structure that can be better connected to the inclined crawler. A cylinder is arranged between the sliding frame and the loading box to facilitate lifting the loading box when the loading box reaches the port of the shredder. The loading box is hinged to the plate-shaped member at the upper end of the sliding frame, so that the loading box is pushed by the cylinder to flip and pour the materials into the shredder.

[0016] In order to ensure that the loading box remains stable during the movement driven by the crawler and also to reduce the burden on the crawler, this application is provided with supporting feet on the sliding frame. The supporting feet contact the conveying frame to provide a certain supporting force for the loading box, thereby reducing the burden on the crawler. At the same time, in order to reduce the friction between the supporting feet and the conveying frame, rollers are arranged at the bottom of the supporting feet. Description of the Drawings

Detailed Description of the Invention

[0024] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following detailed description of the specific embodiments of the present utility model will be provided in conjunction with the accompanying drawings of the specification.

[0025] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. The present utility model provides the following embodiments.

[0027] Please refer to Figure 1 and Figure 5, A high-efficiency shredder, comprising a chassis 100, in which bearing roller shafts 101 are symmetrically arranged. A plurality of cutter teeth 101a are fixedly sleeved on the bearing roller shafts 101 at equal intervals. The bearing roller shafts 101 include a pair of bearing seats, a pair of connecting shafts and a connecting roller. Among them, the pair of bearing seats are respectively embedded in the inner walls at both ends of the chassis 100. The connecting shafts are fixedly connected to the inner rings of the bearing seats. One end of the connecting shaft penetrates through the chassis 100 and is sleeved with a gear 101b. The gears 101b on the pair of bearing roller shafts 101 are meshed with each other. And a driver is externally connected to the end of one of the connecting shafts. The connecting roller is connected to the opposite surfaces of the pair of connecting shafts. The cutter teeth 101a are sleeved on the connecting roller. By driving one of the connecting shafts to rotate through the externally connected driver, the bearing seats are convenient for connecting with the chassis 100 without affecting their own rotation. Furthermore, the relatively moving meshing gears 101b are caused, and the cutter teeth 101a on the connecting roller also move relatively to shred the materials entering the chassis 100. Further, in order to make the connection between the cutter teeth 101a and the connecting roller more firm and prevent the cutter teeth 101a from rotating due to the resistance of the materials during shredding, the cross-section of the connecting roller in this application is a regular polygon structure. Further, in order to facilitate the connection between the connecting roller and the bearing seat, the part connected to the bearing seat is designed as a cylindrical connecting shaft. Therefore, the entire bearing roller shaft 101 is divided into three parts. Fixing screws are drilled on both sides of the cutter teeth 101a on the connecting roller to restrict the cutter teeth 101a; baffles 100a are provided on both sides of the bottom of the chassis 100. The baffles 100a can gather the shredded materials, which is convenient for collecting the separated materials. A bracket 100b is connected to the lower end of the chassis 100. A distance is reserved between the bracket 100b and the baffle 100a. The reserved distance can be used to install a horizontal track. The shredded materials are conveyed through the horizontally arranged track.

[0028] In Figures 2 - 4In this application, aiming at the drawback that when a large shredder uses a crawler conveyor mechanism, the need for inclined installation may cause materials to roll over from the crawler conveyor mechanism and pose a danger, a conveyor frame 200 is integrally connected to the front surface of the chassis 100. The conveyor frame 200 is the frame of the conveyor mechanism. A chute 202 is centrally provided on the conveyor frame 200. Auxiliary rollers 201a are rotatably connected to both ends of the chute 202. A driving roller 201b is provided below one of the auxiliary rollers 201a close to the chassis 100. A crawler 201c is sleeved on the auxiliary rollers 201a and the driving roller 201b. A transport mechanism is slidably connected to the upper surface of the conveyor frame 200. The transport mechanism realizes reciprocating motion through the operation of the crawler 201c, and thus can hold materials at the lowest position and pour the materials into the chassis 100 when moving to the highest position. The auxiliary rollers 201a and the driving roller 201b support the crawler 201c. At the same time, the driving roller 201b is also externally connected to a driver to become a driving component. According to the prior art, the driving roller 201b will have a fixed support component, but this support component does not affect the operation and disclosure of this device, so it is not described in the drawings and the disclosure document. The lower surface of the transport mechanism is fixedly connected to the crawler 201c. The materials are placed in the transport mechanism and are driven by the driving roller 201b to drive the crawler 201c to move obliquely upward and approach the port of the chassis 100. The transport mechanism pours the materials into the chassis 100 and the materials are shredded by the cutter teeth 101a.

[0029] In Figures 2 - 4 this application, since the crawler 201c as the power source is inclinedly installed while the materials need to be transported horizontally during transportation, the transport mechanism of this application includes a sliding frame 203 and a loading box 204 hinged to the upper surface of the sliding frame 203. A convex block is integrally connected to the center of the lower surface of the sliding frame 203. The convex block extends into the chute 202 and is fixedly connected to the conveyor frame 200. The sliding frame 203 is connected to the crawler 201c through the convex block. The loading box 204 is kept horizontal with the crawler 201c in the conveyor frame 200 through the sliding frame 203. Specifically, the upper end of the sliding frame 203 is a plate-like member, so that the loading box 204 is installed thereon to keep horizontal. The lower end of the sliding frame 203 is a triangular structure and can be better connected to the inclined crawler 201c.

[0030] Further, to facilitate the movement of the loading box 204 to the highest position on the conveying rack 200 so as to facilitate pouring the materials loaded inside into the chassis 100, the present application is provided with connecting ears at both ends of one side of the upper surface of the sliding rack 203. The side surface of the loading box 204 is hinged to the connecting ears. Support blocks 203a are provided at both ends of the other side of the upper surface of the sliding rack 203. The loading box 204 is held horizontally by the support blocks 203a. The connecting ears and the support blocks 203a are used to keep a certain distance between the lower surface of the loading box 204 and the upper surface of the sliding rack 203. A cylinder 204a is pin-connected to the upper surface of the sliding rack 203. The output end of the cylinder 204a is pin-connected to the lower surface of the loading box 204. The cylinder 204a is inclined, and when the cylinder 204a works, it moves towards the support block 203a direction, which is convenient for jacking up the loading box 204 when the loading box 204 reaches the port of the chassis 100. The loading box 204 is hinged to the plate-like member at the upper end of the sliding rack 203. Thus, by the push of the cylinder 204a, the loading box 204 is flipped to pour the materials into the chassis 100.

[0031] Furthermore, to keep the loading box 204 stable during operation, sliding blocks are symmetrically provided on the surface of the sliding rack 203 in contact with the conveying rack 200. Chutes 202 are symmetrically provided on the upper surface of the sliding rack 203 and are slidably connected to the sliding blocks. To ensure the stability of the loading box 204 during the movement driven by the crawler 201c and at the same time to reduce the burden on the crawler 201c, supporting feet 203b are symmetrically provided on the other side of the lower surface of the sliding rack 203. The supporting feet 203b are in contact with the conveying rack 200 to provide a certain supporting force for the loading box 204, thereby reducing the burden on the crawler 201c. At the same time, to reduce the friction between the supporting feet 203b and the conveying rack 200, a notch is cut at the bottom of the supporting feet 203b, and a roller is assembled in the notch. The roller is in contact with the conveying rack 200.

[0032] The above content further elaborates on the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present utility model.
