Description

Technical Field

[0001] This invention relates to the field of transfer machine technology, specifically to a structure for preventing material from falling off the load-bearing part of a transfer machine. Background Technology

[0002] The purpose of this invention is to provide a structure for preventing material from falling off the load-bearing part of a transfer machine, so as to solve the problems of transfer machines mentioned in the background art.

[0003] For example, publication number CN211593921U discloses a transshipment machine, including a head frame and a chute. A drag chain device is installed on the head frame, and the chute has a positive side and a negative side. The head frame has a box-like structure, specifically a double-layered middle plate box structure. The high strength of the double-layered middle plate box structure allows it to withstand the strong impacts during scraper transport, completely adapting to the powerful impact force of the scraper, reducing the risk of scraper and chain snagging, and significantly lowering the rate of electromechanical accidents. This reduces the failure rate of the drag chain device on the head frame of the transshipment machine, thus reducing the probability of electromechanical accidents occurring on the transshipment machine.

[0004] However, when the transfer machine is conveying materials upwards, if too much material accumulates in one section, the material will accumulate downwards under the action of gravity, which may exceed the height of the conveying scraper. At this time, the material will fall off the conveyor belt and fall into the machine body, affecting the device. In addition, most of the existing transfer machine's conveying scrapers are fixed to the conveyor belt with screws, which is quite troublesome when the user wants to clean or change the conveying range of the conveying scraper. Summary of the Invention

[0005] The purpose of this invention is to provide a structure for preventing material from falling at the load-bearing part of a transfer machine, so as to solve the problems mentioned in the background art that material accumulation may lead to falling and to facilitate the adjustment of transport spacing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a material-preventing structure at the bearing point of a transfer machine, comprising a transfer machine body, a conveying scraper, a rotating rod, a torsion spring, a limiting hole, and a mounting groove. The transfer machine body has a discharge port, and a conveying plate is fixedly installed inside the transfer machine body. A conveyor belt is connected and installed inside the transfer machine body, and a connecting block is fixedly installed on the conveyor belt. The connecting block has a sliding groove, and a slider is slidably installed on the connecting block. The connecting block has a cavity, and a tension spring is fixedly installed inside the cavity. A limiting block is connected and installed at the upper end of the tension spring.

[0007] A material conveying scraper is connected and installed on the connecting block, and the material conveying scraper has an installation groove and a limit hole. A fixing block is installed inside the material conveying scraper, and a torsion spring is connected and installed inside the fixing block. A rotating rod is installed on the torsion spring, and an elastic cloth is connected and installed on the rotating rod. A rotating shaft is rotatably installed at the lower end of the material conveying scraper, and a load-bearing plate is fixedly installed on the rotating shaft. A baffle is fixedly installed on the material conveying scraper.

[0008] Furthermore, the upper end of the elastic cloth is connected to the rotating rod, and the lower end of the elastic cloth is connected to the upper end of the load-bearing plate, so that the rotating rod and the load-bearing plate form an integrated structure. When the load-bearing plate moves, it will cause the elastic cloth to stretch, thereby preventing the material from falling into the next layer.

[0009] Furthermore, the baffle is triangular in frontal view, and two sets of baffles are symmetrically installed about the vertical central axis of the material conveying scraper. The spacing between the baffles is the same as the length of the load-bearing plate. At the same time, the baffles are connected to the load-bearing plate, and the baffles limit the material on both sides.

[0010] Furthermore, the conveyor belt is symmetrically installed inside the transfer machine, and the material conveying scrapers are evenly distributed on the conveyor belt. The material conveying scrapers are connected to the material conveying plate inside the transfer machine, and the material conveying scrapers transport the material on the material conveying plate to the discharge port.

[0011] Furthermore, the connecting blocks are symmetrically installed on the conveyor belt, and the slider is installed through the connecting blocks via a groove, allowing the slider to slide on the connecting blocks.

[0012] Furthermore, the lower end of the slider is nested into the mounting groove on the conveying scraper, and the limiting spring on the slider is nested into the limiting hole of the mounting groove. The limiting spring fixes the slider, which is engaged in the mounting groove on the conveying scraper.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The anti-material-fall structure at the load-bearing point of this transfer machine is achieved by adding a rotatable load-bearing plate to the transport scraper. When the material rises and accumulates downwards due to gravity, the load-bearing plate will move downwards synchronously under the weight of the material itself, thus providing a certain storage space for the material, reducing the accumulation height of the material, and effectively preventing the material from falling due to accumulation.

[0015] 2. The anti-material-fall structure at the load-bearing point of the transfer machine is achieved by fixing a connecting block on the conveyor belt and connecting the connecting block to the mounting groove on the conveying scraper. This allows the limiting block to engage with the limiting hole to fix the conveying scraper, thereby reducing the installation steps of the conveying scraper and facilitating the assembly of the machine body and the adjustment of the transport section.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-6 The present invention provides a technical solution: a structure for preventing material from falling at the load-bearing part of a transfer machine, comprising a transfer machine body 1, a discharge port 2, a conveyor belt 3, a conveying plate 4, a conveying scraper 5, a baffle 6, an elastic cloth 7, a load-bearing plate 8, a fixing block 9, a rotating rod 10, a torsion spring 11, a rotating shaft 12, a connecting block 13, a slider 14, a limiting block 15, a tension spring 16, a sliding groove 17, a limiting hole 18, a cavity 19, and a mounting groove 20.

[0025] In this embodiment:

[0026] The system includes a transfer body 1, a conveying scraper 5, a rotating rod 10, a torsion spring 11, a limiting hole 18, and a mounting groove 20. The transfer body 1 has a discharge port 2, and a conveying plate 4 is fixedly installed inside the transfer body 1. A conveyor belt 3 is connected and installed inside the transfer body 1, and a connecting block 13 is fixedly installed on the conveyor belt 3. A sliding groove 17 is provided on the connecting block 13, and a slider 14 is slidably installed on the connecting block 13. A cavity 19 is provided on the connecting block 13, and a tension spring 16 is fixedly installed inside the cavity 19. A limiting block 15 is connected and installed at the upper end of the tension spring 16.

[0027] A material conveying scraper 5 is connected and installed on the connecting block 13, and the material conveying scraper 5 has an installation groove 20 and a limit hole 18. At the same time, a fixing block 9 is installed inside the material conveying scraper 5, and a torsion spring 11 is connected and installed inside the fixing block 9. A rotating rod 10 is installed on the torsion spring 11, and an elastic cloth 7 is connected and installed on the rotating rod 10. A rotating shaft 12 is rotatably installed at the lower end of the material conveying scraper 5, and a load-bearing plate 8 is fixedly installed on the rotating shaft 12. A baffle 6 is fixedly installed on the material conveying scraper 5.

[0028] The upper end of the elastic cloth 7 is connected to the rotating rod 10, and the lower end of the elastic cloth 7 is connected to the upper end of the load-bearing plate 8, so that the rotating rod 10 and the load-bearing plate 8 form an integrated structure. When the load-bearing plate 8 moves, it will drive the elastic cloth 7 to stretch, thereby preventing the material from falling into the next layer. The baffle 6 is triangular in frontal view, and two sets of baffles 6 are symmetrically installed about the vertical central axis of the conveying scraper 5. The spacing between the baffles 6 is the same as the length of the load-bearing plate 8. At the same time, the baffles 6 are connected to the load-bearing plate 8, and the baffles 6 limit the material on both sides. The conveyor belt 3 is symmetrically installed in the transfer machine body 1, and the conveying scrapers 5 are evenly distributed on the conveyor belt 3. The conveying scrapers 5 are connected to the conveying plate 4 in the transfer machine body 1, and the material on the conveying plate 4 is transported to the discharge port 2 by the conveying scrapers 5.

[0029] Connecting blocks 13 are symmetrically installed on conveyor belt 3, and slider 14 is installed through connecting blocks 13 via sliding groove 17, so that slider 14 can slide on connecting blocks 13. The lower end of slider 14 is nested into the mounting groove 20 on conveying scraper 5, and tension spring 16 on slider 14 is nested into the limiting hole 18 of mounting groove 20. Tension spring 16 fixes slider 14, which is engaged in mounting groove 20 on conveying scraper 5.

[0030] Working principle: When using this device, first install it in the correct position. After installation, connect the transfer machine body 1 to the external power supply and start the conveyor belt 3. When the material is placed on the conveyor plate 4, the conveying scraper 5 connected to the conveyor plate 4 will drive the material on the conveyor plate 4 to move upward. As the height increases, the material will accumulate downward under the action of gravity. Under the gravity of the material, the load-bearing plate 8 will tilt to the right through the rotating shaft 12. When the load-bearing plate 8 tilts, it will pull the elastic cloth 7 out of the rotating rod 10. After the height increase is completed, the torsion spring 11 on the elastic cloth 7 will pull the load-bearing plate 8 to reset, effectively preventing the falling caused by the continuous accumulation of material.

[0031] When the spacing of the conveying scraper 5 needs to be adjusted according to different materials, the limiting block 15 in the upper limit hole 18 of the mounting groove 20 can be pressed, and then the slider 14 can be moved through the slide groove 17 to make the limiting block 15 on the slider 14 stop engaging with the limiting hole 18. The slider 14 can then be pulled out of the mounting groove 20, releasing the limiting of the conveying scraper 5. Thus, after the conveying scraper 5 is adjusted to a suitable position on the conveyor belt 3, the limiting block 15 can be re-engaged into the limiting block 18, greatly saving installation time.
