Description

Technical Field

[0001] The utility model relates to the technical field of machine-made sand processing, in particular to a feeding mechanism for machine-made sand processing. Background Art

[0002] In the process of machine-made sand production, the production equipment and processing procedures of different materials are different, but the general production process is the same, which is generally divided into five stages: pretreatment-crushing-sand making-screening-sand washing.

[0003] The Chinese patent document with application number CN202122225390.0 in the related technology proposes a vibrating feeder for machine-made sand production. When the operator adds the raw materials into the inclined pipe from the feed port, the motor body is started at this time. The motor body drives the arc block to rotate through the installed circular shaft. Under the action of the metal shaking plate, the inclined pipe can be vibrated as a whole, and the machine-made sand will move downward through the inclined pipe, so that the machine-made sand can be filtered through the filter screen. When the vibrating feeder finishes feeding, the operator can hold and pull the pulling belt outward to bring out the filter screen. At this time, the stones and other debris filtered on the upper side of the filter screen will be scraped out by the scraping block. The operator can hold and pull the handle upward to make the ejection needle insert into the gap of the filter screen, thereby pushing out the debris stuck between the filter screens and achieving a cleaning effect.

[0004] After further search, the "automatic feeding device for machine-made sand production" disclosed in the application number "CN202022766011.4" is found. When it is used, the sand and gravel are first put into the feed hopper, and then the sand and gravel fall onto the first guide plate through the feed hopper, and the sand and gravel are filtered by the sand filter net. The large sand and gravel particles are retained on the first guide plate, and the small sand and gravel particles fall onto the second guide plate. At this time, the vibrator is started, and the second guide plate is driven to vibrate by the vibrator, and then under the action of the fixed plate and the connecting plate, the first guide plate is driven to vibrate, so that the sand and gravel on the first guide plate and the second guide plate slide along the guide groove into the storage box. Immediately afterwards, the first shock-absorbing spring can play a buffering role when the vibrator drives the second guide plate to vibrate. In addition, the second shock-absorbing spring plays a buffering role on the vibrator. Then, the dust generated when the sand and gravel are shaken off can be absorbed by the vacuum cleaner to prevent the dust from being absorbed by the staff.

[0005] Regarding the related technologies in the above two disclosed technologies, the inventor believes that there are the following defects: it is inconvenient to adjust the feeding pipe to the height of the sand making machine, the stones remaining on the screen can easily clog the screen, and it is inconvenient to clean the screen. Therefore, the utility model provides a machine-made sand processing feeding structure. In view of this, a machine-made sand processing feeding mechanism is proposed to solve the above problems.

[0009] One side of the second slider is hinged with the first movable rod, and the second movable rod is attached to one side of the first movable rod. A rotating rod passes through the fitting part of the first movable rod and the second movable rod. The top end of the second movable rod is hinged with the first slider, and the inner wall of the first slider is penetrated by the second guide rod.

A vibration motor 404 is fixed in the middle of the bottom end of the circular frame 403.

[0025] The lifting mechanism 2 includes a threaded rod 204, a rotatable threaded rod 204 is horizontally arranged in the bottom box 1, an external first motor for driving the threaded rod 204 to rotate is fixed on the bottom box 1, a threaded sleeve 209 is threadedly connected to the threaded rod 204, and connecting rods 208 are fixed at both ends of the threaded sleeve 209, and a second slider 207 is fixed at one end of the connecting rod 208. A first guide rod 203 is slidably installed in the second slider 207, and both ends of the first guide rod 203 are fixed to the bottom wall of the inner cavity of the bottom box 1.

[0026] One side of the second slider 207 is hinged with the first movable rod 201, and the second movable rod 202 is attached to one side of the first movable rod 201. The fitting part of the first movable rod 201 and the second movable rod 202 is penetrated by a screw rod 210. The top of the second movable rod 202 is hinged with the first slider 205, and the inner wall of the first slider 205 is penetrated by a second guide rod 206. The top ends of the second guide rod 206 are fixed to the lower end of the bottom box 1.

[0027] The device starts the external first motor, which drives the threaded rod 204 to rotate, and then drives the connecting rod 208 on the threaded sleeve 209 to move through the threaded rod 204, so that the connecting rod 208 drives the two groups of second sliders 207 to slide along the outer walls of the two groups of first guide rods 203.

[0030] Please refer to the figure. The cleaning mechanism 3 in this embodiment includes an electric push rod 301. The electric push rod 301 is vertically arranged on the screening box 8. The output end of the electric push rod 301 is fixed with a mounting plate 302. The inclination angle of the mounting plate 302 is the same as the inclination angle of the circular frame 403, so that when the screen nails 303 move downward, they can be inserted into the filter holes on the screen 401 for dredging. The lower end of the mounting plate 302 is fixed with screen nails 303 that are equidistantly arranged in an orderly manner.

[0031] The device starts the electric push rod 301, which drives the mounting plate 302 to move, and then the mounting plate 302 drives the screen nails 303 to move downward to clear the filter holes of the screen 401, preventing the filter holes of the screen 401 from being blocked by stones.

[0032] The working principle of the above embodiment is:

[0033] During use, by starting the external first motor, the external first motor drives the threaded rod 204 to rotate, and then the threaded rod 204 drives the connecting rod 208 on the threaded sleeve 209 to move, so that the connecting rod 208 drives the two groups of second sliders 207 to slide along the outer walls of the two groups of first guide rods 203. Under the rotation of the rotating rod 210, the two groups of second sliders 207 drive the two groups of first movable rods 201 and the two groups of second movable rods 202 to rotate, so that the two groups of first sliders 205 slide along the outer walls of the two groups of second guide rods 206, driving the screening box 8 to rise to a suitable height, and then adjusting the height of the discharge pipe 6, and adjusting the discharge pipe 6 to the feed port of the sand making machine.

[0034] Then start the vibration motor 404, pour the stone from the feed hopper, the stone is on the screen 401, and after screening by the screen 401, the small particles of stone fall to the bottom of the screening box 8 and flow into the discharge pipe 6, and then enter the sand making machine. The large particles of stone roll from the screen 401 into the installation box 701, and then start the external second motor. The external second motor drives the rotating rod 703 and the spiral blade 702 to rotate. The spiral blade 702 rotates to guide the stone into the discharge pipe, and the large particles of stone are collected and further processed. Finally, start the electric push rod 301, and the electric push rod 301 drives the mounting plate 302 to move, and then the mounting plate 302 drives the screen nails 303 to move downward to clear the filter holes of the screen 401 to prevent the stone from clogging the filter holes of the screen 401.
