Description

Technical Field

[0001] The present application relates to the technical field of material discharging for color sorters, and in particular to a material discharging mechanism for a rice color sorter. Background Art

[0002] In the field of grain processing, rice color sorter is a key equipment for color screening of rice. However, the existing rice color sorter unloading mechanism often has blockage problems, resulting in reduced equipment efficiency and increased maintenance costs. The current technical solutions mainly use vibration unloading or simple slide design, which are prone to blockage due to material accumulation or poor flow when processing large amounts of materials. Once blocked, the machine needs to be stopped for cleaning, which reduces production efficiency and increases operating costs; therefore, we propose a rice color sorter unloading mechanism to solve this problem.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0004] In order to solve the problem that in actual operation, impurities such as sand, gravel, and worm-eaten rice grains may be mixed into the rice, and these impurities may easily cause blockage in the slideway, affecting the normal operation of the feeding mechanism, the present application provides a feeding mechanism for a rice color sorter.

[0005] The present application provides a rice color sorter unloading mechanism that adopts the following technical solution:

[0006] A rice color sorter unloading mechanism comprises a housing, a PLC controller is arranged on the front side of the housing, a first unloading pipe is fixedly connected to the top of the housing, a conveyor belt is arranged below the housing, an anti-blocking mechanism is arranged on the housing, and a transmission mechanism is arranged on the anti-blocking mechanism;

[0007] The anti-blocking mechanism includes a rotating rod, a plurality of connecting rods are fixedly connected to the outer side of the rotating rod, a plurality of connecting rods are rotatably connected to the outer sides of the plurality of connecting rods, a second bevel gear is fixedly connected to one end of the rotating rod, and the rotating rod is rotatably connected to the inner side of the first discharge pipe.

[0008] Preferably, the transmission mechanism comprises a motor, the motor is fixedly connected to the top of the housing, and the output end of the motor is connected to a transmission wheel via a coupling.

[0009] Preferably, the outer side of the transmission wheel is rotatably connected to a transmission belt, the inner side of the transmission belt is rotatably connected to a threaded rod, and the outer side of the threaded rod is threadedly connected to a moving block.

[0010] Preferably, a second feeding pipe is slidably connected to the inner side of the first feeding pipe, and the second feeding pipe is fixedly connected to the outer side of the moving block.

[0011] Preferably, a first bevel gear is fixedly connected to the bottom of the threaded rod, and the first bevel gear is meshed with the outer side of the second bevel gear.

[0012] Preferably, the rotating rod and the threaded rod are rotatably connected to the inner side of the connecting shell at one end close to the motor.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The rotation of the threaded rod drives the first bevel gear at the bottom to rotate. Because the first bevel gear and the second bevel gear are meshed with each other, the rotation of the threaded rod can drive the rotating rod to rotate. When the rotating rod rotates, the rotating rod drives the outer connecting rod and the roller to rotate, thereby clearing the material blocked inside the discharge pipe, effectively preventing the blockage of the discharge mechanism and improving the discharge efficiency;

[0015] 2. The space of the material discharge pipeline can be contracted through a motor, and the efficiency of clearing blockages can be improved by increasing the activity space of the materials in the pipeline. Due to the rotating connection between the connecting rod and the roller, the rigid clearing of the anti-blocking device is avoided, and the clearing work can be carried out while protecting the materials.

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a rice color sorting machine feeding mechanism. Figure 1A rice color sorter feeding mechanism comprises a shell 1, a PLC controller 2 is arranged on the front side of the shell 1, a first feeding pipe 3 is fixedly connected to the top of the shell 1, a conveyor belt 4 is arranged below the shell 1, an anti-blocking mechanism is arranged on the shell 1, and a transmission mechanism is arranged on the anti-blocking mechanism;

[0022] The anti-blocking mechanism includes a rotating rod 14, a plurality of connecting rods 15 are fixedly connected to the outer side of the rotating rod 14, and a roller 16 is rotatably connected to the outer side of the plurality of connecting rods 15. One end of the rotating rod 14 is fixedly connected to the second bevel gear 13, and the rotating rod 14 is rotatably connected to the inner side of the first discharge pipe 3; the rotation of the threaded rod 9 drives the bottom first bevel gear 12 to rotate, and because the first bevel gear 12 and the second bevel gear 13 are meshed with each other, the rotation of the threaded rod 9 can drive the rotating rod 14 to rotate. When the rotating rod 14 rotates, the rotating rod 14 drives the outer connecting rod 15 and the roller 16 to rotate, thereby clearing the material blocked on the inner side of the discharge pipe.

[0023] Reference Figure 2-3 The transmission mechanism includes a motor 5, which is fixedly connected to the top of the housing 1. The motor 5 is fixedly connected to the top of the housing 1 to prevent the motor 5 from rotating on its own and improve the stability of the motor 5 during operation. The output end of the motor 5 is connected to a transmission wheel 6 through a coupling.

[0024] Reference Figure 3 The outer side of the transmission wheel 6 is rotatably connected to a transmission belt 7, the inner side of the transmission belt 7 is rotatably connected to a threaded rod 9, and the outer side of the threaded rod 9 is threadedly connected to a moving block 8; the transmission belt 7 is used to realize synchronous rotation of the threaded rod 9 and the motor 5.

[0025] Reference Figure 1 The inner side of the first feeding pipe 3 is slidably connected to the second feeding pipe 10 , and the inner wall of the first feeding pipe 3 serves as a guide for the second feeding pipe 10 . The second feeding pipe 10 is fixedly connected to the outer side of the moving block 8 .

[0026] Reference Figure 3 The bottom of the threaded rod 9 is fixedly connected with a first bevel gear 12, and the first bevel gear 12 is meshed with the outer side of the second bevel gear 13; when the first bevel gear 12 rotates, the first bevel gear 12 drives the second bevel gear 13 to rotate.

[0027] Reference Figure 1 and Figure 3 The rotating rod 14 and the end of the threaded rod 9 close to the motor 5 are rotatably connected to the inner side of the connecting shell 11.

[0028] The implementation principle of a rice color sorter unloading mechanism of the present application embodiment is as follows: when the device is used and the device cannot operate due to material blockage, the staff first operates the PLC controller 2, and the PLC controller 2 transmits a signal to the motor 5. The motor 5 drives the transmission wheel 6 at one end of the output shaft to rotate through the coupling. When the transmission wheel 6 rotates, the transmission wheel 6 drives the outer transmission belt 7 to rotate. When the transmission belt 7 rotates, the transmission belt 7 drives the inner threaded rod 9 to rotate. When the threaded rod 9 rotates, the threaded rod 9 drives the outer threaded movable block 8 to move. Since the movable block 8 is fixedly connected to the outer side of the second unloading pipe 10, the second unloading pipe 10 is slidably connected to the inner side of the first feeding tube 3, so the rotation of the motor 5 can make the second feeding tube 10 slide upward along the inner wall of the first feeding tube 3, thereby increasing the pipeline space between the second feeding tube 10 and the first feeding tube 3, and at the same time, the rotation of the threaded rod 9 drives the bottom first bevel gear 12 to rotate, and because the first bevel gear 12 and the second bevel gear 13 are meshed with each other, the rotation of the threaded rod 9 can drive the rotating rod 14 to rotate. When the rotating rod 14 rotates, the rotating rod 14 drives the outer connecting rod 15 and the roller 16 to rotate, thereby clearing the material blocked in the inner side of the feeding tube, effectively preventing the blockage problem of the feeding mechanism and improving the feeding efficiency;

[0029] The space of the material discharge pipe can be shrunk by a motor 5, and the efficiency of clearing blockage is improved by increasing the activity space of the material in the pipe. The rotational connection between the connecting rod 15 and the roller 16 avoids rigid clearing of blockage by the anti-blocking device, and clearing blockage is performed while protecting the material.
