Description

A thin-shelled pecan grading and sorting machine Technical Field

[0001] This utility model relates to the field of sorting machine technology, and in particular to a grading and sorting machine for thin-shelled pecans. Background Technology

[0002] An existing thin-shelled pecan grading and sorting machine uses a drum screen to sort the pecans. However, this method fails to consider that when the pecans enter the drum screen, larger pecans may block the small holes, causing smaller pecans to fall into the larger ones, thus failing to achieve the desired grading and sorting effect. For example, a thin-shelled pecan grading and sorting machine disclosed in Chinese Patent No. CN202420468418.4 uses a primary, secondary, and tertiary sorting device for sorting. The sorting devices are mounted on the side of the feeding device via a frame, with the height decreasing at each stage. However, this method does not consider that larger pecans may block the holes in the small pecan sorting device, causing smaller pecans to fall into the larger ones, thus failing to achieve the desired grading and sorting effect. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a thin-shelled walnut grading and sorting machine. By using a second motor to drive the screw conveyor to rotate at different speeds, the walnuts brought in from the feed hopper can be dispersed, avoiding blockage and accumulation. A second vibrator drives the conveyor belt to vibrate continuously, dispersing adjacent walnuts and reducing the possibility of small walnuts pressing against larger walnuts in the grading drum screen. Simultaneously, the cooperation of the hydraulic cylinder and hydraulic rod can adjust the tilt angle of the conveyor belt, accelerating the conveying speed and improving work efficiency. A first vibrator drives the brush to vibrate, cleaning up walnuts or debris clogging the grading drum screen and keeping the machine clean.

[0004] This utility model also provides a thin-shelled pecan grading and sorting machine, comprising: a feeding hopper, a conveying box fixedly connected to the lower surface of the feeding hopper, a screw conveyor rotatably connected inside the conveying box, a support frame fixedly connected to the side surface of the feeding hopper, and the support frame fixedly connected to the conveying box; a motor, a support frame fixedly connected to the lower surface of the motor, a rotating shaft fixedly connected to the output end of the motor, a grading drum screen fixedly connected to the side surface of the rotating shaft, and a rotatably connected end of the rotating shaft away from the motor; a brush plate, bristles fixedly connected to the lower surface of the brush plate, a vibrator fixedly connected to the upper surface of the brush plate, a fixing frame fixedly connected to the side surface of the brush plate, the lower surface of the fixing frame fixedly connected to the support frame, and a fixing frame fixedly connected to the side of the brush plate away from the fixing frame, the lower surface of the fixing frame fixedly connected to the support frame. Through the aforementioned components, the screw conveyor can reduce the conveying speed and density of materials, avoiding blockages caused by accumulation; the grading drum screen can separate walnuts into different grades of large, medium, and small, improving grading efficiency and reducing labor costs; and the vibrator vibrates the brush bristles to clean clogged screen holes and keep the drum screen clean.

[0005] According to the thin-shelled pecan grading and sorting machine provided by this utility model, a second motor is fixedly connected to the side surface of the feeding box, and a second rotating shaft is fixedly connected to the output end of the second motor. Through these components, the second motor can drive the rotating shaft to rotate, reducing wasted time and lowering costs.

[0006] According to the present invention, a thin-shelled pecan grading and sorting machine is provided, wherein the end of the second rotating shaft away from the second motor is located inside the feeding box, and the second rotating shaft is fixedly connected to the screw conveyor. Through the above components, the screw conveyor rotates continuously, preventing blockage inside the feeding box.

[0007] According to the present invention, a thin-shelled pecan grading and sorting machine is provided, wherein a conveyor belt is movably connected to the side surface of the feeding box, and a vibrator is fixedly connected to the lower surface of the conveyor belt. Through these components, the vibrator causes the conveyor belt to vibrate continuously during operation, thus dispersing adjacent pecans.

[0008] According to the present invention, a thin-shelled pecan grading and sorting machine is provided, in which a hydraulic cylinder is fixedly connected to the lower surface of the conveyor belt, and a hydraulic rod is fixedly connected to the output end of the hydraulic cylinder. Through these components, the hydraulic cylinder can drive the hydraulic rod to extend and retract vertically, thereby adjusting the tilt angle of the conveyor belt and preventing accumulation.

[0009] According to the present invention, a thin-shelled pecan grading and sorting machine is provided, wherein a groove is provided on the side surface of the support frame one, and a rotating shaft three is rotatably connected inside the groove, with the end of the rotating shaft three away from the groove fixedly connected to the conveyor belt. Through the above components, the tilt angle of the conveyor belt can be adjusted, improving work efficiency and avoiding accumulation caused by too small a tilt angle.

[0010] According to the thin-shelled pecan grading and sorting machine provided by this utility model, a base plate is fixedly connected to the lower surface of the second support, and a collection box is fixedly connected to the upper surface of the base plate. These components can fix the position of the collection box, preventing large pecans from falling into the box for smaller pecans.

[0011] According to the present invention, a thin-shelled pecan grading and sorting machine is provided, wherein a support bracket three is fixedly connected to the upper surface of the base plate, and a discharge hopper is fixedly connected to the upper surface of the support bracket three. These components fix the position of the discharge hopper, preventing misalignment, increasing the stability of the discharge hopper, and improving work efficiency.

[0012] Compared with existing technologies, this thin-shelled pecan grading and sorting machine uses a second motor to drive the screw conveyor to rotate at different speeds, which can disperse the pecans brought in by the feed hopper and avoid blockage and accumulation. The second vibrator drives the conveyor belt to vibrate continuously, which disperses adjacent pecans and reduces the possibility of small pecans pressing against large pecans in the grading drum screen. At the same time, the cooperation of the hydraulic cylinder and hydraulic rod can adjust the tilt angle of the conveyor belt, speed up the conveying speed, and improve work efficiency. The first vibrator drives the brush to vibrate, which can clean up the pecans or debris blocking the grading drum screen and keep the machine clean. Attached Figure Description
