Detailed Description
Example 1:
referring to fig. 1, the present embodiment provides a vibratory screening machine 100 including a housing 130, a first screen assembly 110, a coarse blanking tube 132, a fine blanking tube 136, support springs 150, and a vibratory apparatus 140. First screen assemblies 110 are positioned in housing 130 and attached to housing 130 by support springs 150, and vibratory apparatus 140 is used to provide an exciting force to the first screen assemblies; the coarse grain discharge pipe 132 and the fine grain discharge pipe 136 are used for discharging the screened fertilizer particles with different particle sizes.
Specifically, the case 130 is a rectangular parallelepiped case 130 structure welded by steel plates. The bottom of the shell 130 is provided with a support rod, and the shell 130 is fixedly connected with the foundation through the support rod. The upper portion of the housing 130 is provided with a feed inlet, which is provided with a feed hopper 138. Fertilizer particles are fed from feed hopper 138 to screen assemblies in housing 130. A rectangular bottom plate is disposed inside the housing 130, and four support springs 150 are disposed on the bottom plate in a matrix arrangement.
A coarse grain blanking pipe 132 and a medium grain blanking pipe 134 are arranged at the lower part of the shell 130, the coarse grain blanking pipe 132 is arranged below the second end of the first screen, and the fine grain blanking pipe is arranged below the screen surface of the first screen; also, the bottom plate of the housing 130 is obliquely disposed so that the fertilizer falling onto the bottom plate is easily flowed.
Referring to fig. 2, vibratory apparatus 140 includes a cam 142 and a connecting shaft 144, where connecting shaft 144 is vertically disposed and rotatably connected to the bottom plate of housing 130, cam 142 is connected to the connecting shaft, cam 142 is disposed between first screen assembly 110 and the sidewall of housing 130, and the outer contour of cam 142 abuts against the side of frame 112 of first screen assembly 110. As cam 142 rotates, cam 142 drives first screen assembly 110 in a reciprocating motion. In other embodiments, vibratory apparatus 140 may also employ a commercially available vibratory motor that is coupled to first screen assembly 110 to drive it in a vibratory motion.
Referring to fig. 3 and 4, in order to prevent fertilizer from flowing on the screen surface of the first screen 124 and causing blockage, in this embodiment, the vibratory screening machine 100 further includes a scraping assembly 160, the scraping assembly 160 is disposed above the first screen 124, and the scraping assembly 160 includes a driving mechanism and a plurality of strip-shaped scrapers 162; the drive mechanism is used to drive the scraper 162 across the mesh surface of the first screen 124 to feed fertilizer from the first end to the second end.
Specifically, the driving mechanism includes a motor (not shown), a driving shaft 1611 and a driven shaft 1615, the driving shaft 1611 and the driven shaft 1615 are disposed inside the housing 130 and are spaced apart from each other in parallel, and both ends of the driving shaft 1611 and the driven shaft 1615 are rotatably connected to both side walls of the housing 130. Two ends of the driving shaft 1611 are respectively provided with a driving chain wheel 1612, and two ends of the driven shaft are respectively provided with a driven chain wheel 1613; the two drive sprockets 1612 and the two driven sprockets 1613 are connected by a chain 1614, respectively. The scrapers 162 extend in the width direction of the first screen 124, and both ends thereof are connected to two chains 1614, respectively; the plurality of flights 162 are evenly distributed along the chain 1614. Since the scraper assembly 160 is disposed above the first screen 124, the chain 1614 is divided into two parallel spaced apart portions by the sprocket; thus, the lower flight 162 of the chain 1614 is adjacent to the wire side of the first screen 124, and the upper flight 162 is spaced from the wire side of the first screen 124. When the chain 1614 is driven, the scraper 162 moves in a circular motion with the chain 1614, thereby continuously scraping the first screen 124. In particular applications, the scraper assembly 160 may be continuously activated or may be activated when fertilizer on the first screen 124 is not flowing well.
The working principle of the vibrating screen machine 100 provided by the embodiment is as follows:
after the fertilizer is fed from the feed port of the housing 130 onto the first screen 124, the fertilizer flows from the first end toward the second end due to the first screen 124 being disposed obliquely and the vibration device 140 driving the first screen 124 to vibrate. During flow, coarse falls from the second end and exits through the coarse blanking pipe 132 below the second end; the finer fertilizer falls through the openings in the first screen 124 and out through the lower medium particle discharge pipe 134. When more fertilizer is on the first screen 124, resulting in a poor feed, the scraper assembly 160 is activated and the scraper 162 is able to scrape the fertilizer on the first screen 124 from the first end to the second end.
Example 2:
referring to fig. 5, this embodiment is based on embodiment 1 and adds a second screen assembly 120 and a fine blanking pipe 136 to facilitate the separation of the fertilizer into coarse, medium and fine categories.
Specifically, the second screen assembly 120 is disposed below the first screen assembly 110 and includes a second screen having a smaller mesh size than the second screen such that fertilizer falling through the mesh of the first screen can be screened through the second screen. The second screen is connected with the supporting spring 150, and since the first screen can continuously vibrate under the action of the vibration device 140, the vibration can be transmitted to the second screen through the supporting spring 150, so that the continuous vibration thereof realizes the screening of fertilizer. Of course, it is also possible to install a separate vibratory device 140 for second screen assembly 120.
A fine particle blanking pipe 136 is provided below the second screen, and fertilizer falling from the screen holes of the second screen can fall into the fine particle blanking pipe 136.
In this embodiment, in order to facilitate the butt joint of the medium particle discharging pipe 134 and the second end of the second screen, the length of the second screen is smaller than that of the first screen; when installed, the first ends of the first and second screens are aligned such that the second end of the first screen extends beyond the second end of the second screen, thereby leaving an installation space for the medium discharge pipe 134.
In order to prevent the fertilizer falling from the holes of the first screen from directly falling into the medium particle blanking pipe 134 without being screened by the second screen, the vibrating type screening machine in this embodiment is further provided with a guide plate 170, one end of which is connected with the upper end of the coarse particle blanking pipe 132, and the other end of which is inclined downwards to extend to the upper side of the second screen.
In addition, in this embodiment, the scraper assembly provided in embodiment 1 is also positioned above second screen assembly 120.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
