DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the invention, and to enable those of ordinary skill in the art to understand the invention and design various inventions with various modifications suitable for specific uses.

[0024] See also Figures 1 to 8 The present invention provides an unmanned hopper device for port loading, including a hopper body 1 and a filter screen 2, wherein a discharge port is installed at the bottom of the hopper body 1, a control valve 11 is installed on the outer wall of the discharge port, an inclined ring plate 12 is installed on the inner wall of the hopper body 1, a plurality of connecting columns 13 are installed on the upper end surface of the inclined ring plate 12 along its circumferential direction, a spring rod 19 is installed on the upper end surface of the connecting column 13, and a filter screen 2 is installed on the upper end surface of the spring rod 19. During operation, when the port transports materials, the materials enter the hopper body 1, and the filter screen 2 filters the materials so that large particles of materials remain on the filter screen 2. During the material entering process, the spring rod 19 drives the filter screen 2 to shake up and down, further ensuring the filtering effect.

[0025] A right vertical frame 14 is installed at the right end of the outer wall of the material port body, an electric slider 18 is installed on the upper end surface of the right vertical frame 14, an L-shaped frame 15 is installed on the upper end surface of the electric slider 18, a top plate is installed at the bottom of the L-shaped frame 15, an adjusting cylinder 16 is installed on the upper end surface of the top plate, and a pressing plate 17 is installed at the output end of the adjusting cylinder 16. When working, the electric slider 18 is a linear guide slider structure, so as to control the operation of each device. When working, the adjusting cylinder 16 is started to drive the pressing plate 17 to move downward, so as to crush the material on the filter screen 2 so that it can fall. When the operation is completed, the electric slider 18 is started to drive the pressing plate 17 to move right, so as not to affect the normal operation of the hopper body 1.

[0026] A left upright frame 21 is installed at the left end of the outer wall of the hopper body 1, and a fixing groove is opened on the end face of the left upright frame 21. A return spring 22 is installed on the left end face of the fixing groove, and a first slider is installed on the other end of the return spring 22. A vertical plate 23 is installed on the upper end face of the first slider, and an upper rod 24 is installed on the right end face of the vertical plate 23. A lower rod 25 is arranged below the upper rod 24, and an adjusting cam 26 is arranged on the left side of the vertical plate 23. A first motor 27 is arranged behind the adjusting cam 26. When working, the first motor 27 is started to drive the adjusting cam 26 to rotate, so that the vertical plate 23 moves left and right, so that the upper rod 24 can perform a tapping and vibration treatment on the pressing plate 17, so that the material adhered to the bottom of the pressing plate 17 can fall down, avoiding waste of materials, and the lower rod 25 can perform a tapping and vibration treatment on the side wall of the hopper body 1, thereby avoiding clogging of the filter screen 2, further improving the filtering effect.

[0027] An outer cylinder 28 is obliquely arranged on the outer wall of the hopper body 1, and a first spring 29 is installed at the bottom of the outer cylinder 28. A movable rod 291 is installed at the other end of the first spring 29. The movable rod 291 is connected to the outer cylinder 28 by sliding fit. An outer plate is installed on the outer wall of the movable rod 291, and a fixed plate is symmetrically installed on the outer wall of the outer cylinder 28. A control button 292 is installed obliquely above the fixed plate. The control button 292 is electrically connected to the control valve 11. During operation, when materials fall, they accumulate at the bottom of the hopper body 1. When there are enough materials, the movable rod 291 will be pressed, so that the movable rod 291 moves down to press the control button 292, so that the first valve opens, and the materials can fall naturally. When there are less materials, the first spring 29 controls the movable rod 291 to reset, so that the first valve is closed, so that the materials can be packed independently, thereby improving the convenience of using the device.

[0028] Preferably: a lower plate 293 is rotatably installed on the inner end of the right vertical frame 14 through a pin shaft, a second spring 294 is installed at the bottom of the lower plate 293, and the other end of the second spring 294 is installed on the inner end of the right vertical frame 14. During operation, there is a gap in the outer cylinder 28, and a small amount of material is discharged through the outer cylinder 28 and falls onto the lower plate 293. When the amount is large enough, the lower plate 293 is pressed to rotate, thereby entering the container body to avoid waste of materials.

[0029] A control panel 295 is installed on the right side end surface of the right stand 14. The control panel 295 is electrically connected to the electric slider 18. A PLC program is written in the control panel 295 to control the operation of each device.

[0030] During specific operation, when the port transports materials, the materials enter the hopper body 1, and the filter screen 2 filters the materials so that large particles remain on the filter screen 2. During the entry of materials, the spring rod 19 drives the filter screen 2 to shake up and down, further ensuring the filtering effect. When the materials fall, they accumulate at the bottom of the hopper body 1. When there are enough materials, the movable rod 291 will be pressed, causing the movable rod 291 to move down and press the control button 292, so that the first valve opens and the materials can fall naturally. When there are less materials, the first spring 29 controls the movable rod 291 to reset, so that the first valve closes, so that the materials can be packed independently, thereby improving the convenience of using the device.

Based on the invention of the present invention, all other inventions obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
