[0002] The drop ladder is a kind of grain storage supporting equipment, which is used to control the flow and direction of grain in the storage process. The drop ladder has a reversing structure and a controllable reversing structure to facilitate the transportation of grain to grain storage bins in different directions. The drop ladder is distributed outside the grain storage bin, and the grain is transported from bottom to top by a conveyor belt. The drop ladder is usually used to transport rice and other grains with high resistance to falling. The top of the drop ladder usually extends to the inside of the grain storage bin.

[0003] In the process of the existing drop ladder delivering grain to the grain storage bin, since the grain is exposed to the air on the drop ladder, the dust mixed in the grain will diffuse in the air outside the grain storage bin and inside the grain storage bin during the process of the grain falling into the grain storage bin. The dust will affect the workers' observation of the grain transportation and cause pollution to the grain storage environment. The dust will also affect the workers' health. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides Figure 1-Figure 3 The controllable grain-distributing drop ladder for the grain storage bin shown in the figure comprises a base 14, two supports 20 are arranged on the top of the base 14, an axis 21 is arranged between the two supports 20, a frame 7 is arranged outside the axis 21, rollers 81 are arranged at both ends of the frame 7, a conveyor belt 8 is arranged outside the roller 81, a rotatable feed box 2 is arranged at the top of the frame 7, a feed port 1 is opened at the bottom of the feed box 2, and a plurality of air holes are opened on one side wall of the feed box 2, a dust collecting plate 24 is arranged on the side of the outer wall of the feed box 2 close to the air hole, one end of the dust collecting plate 24 is connected to a hose 22, and one end of the hose 22 is connected to a dust collector 23; a drive motor 15 is arranged at one end of the frame 7, the output shaft of the drive motor 15 is connected to the roller 81, and a plurality of push hoppers 9 are also arranged on the outer wall of the conveyor belt 8;

[0024] Specifically, in the process of conveying grain, the top of the frame 7 is aligned with the feed window of the grain storage bin (not shown in the figure), the grain is placed on the conveyor belt 8, and the drive motor 15 is started. The output shaft of the drive motor 15 drives the roller 81 to rotate and drives the conveyor belt 8 to move. The grain falls on the conveyor belt 8 and the push hopper 9. The conveyor belt 8 and the push hopper 9 drive the grain to move. The grain is conveyed from the bottom position of the frame 7 to the top position of the frame 7. Finally, the grain is thrown out from the top of the frame 7, and the vacuum cleaner 23 is started. The vacuum cleaner 23 draws air. The air passes through the air holes on the inner side of the feed box 2 into the interior of the dust collecting plate 24, passes through the hose 22, and then enters the vacuum cleaner 23. The vacuum cleaner 23 has a filter cloth inside to filter dust. The internal structure of the vacuum cleaner 23 is the prior art and will not be described here.

[0025] like Figure 1-Figure 3As shown, specifically, mounting brackets 6 are provided on both side walls of the feed box 2, and fastening bolts 5 are provided between the mounting brackets 6 and the feed box 2, and the extending ends of the mounting brackets 6 are connected to the top outer wall of the frame 7; it should be noted that by manually rotating the fastening bolts 5 counterclockwise, the fastening bolts 5 are in a loosened state, and the feed box 2 is in a loose and unstable state on the mounting brackets 6, and the inclination angle of the feed box 2 is adjusted by hand, so that the direction of the feed port 1 of the feed box 2 can be adjusted to adapt to the discharge angle of the conveyor belt 8 after the frame 7 is lifted or lowered.

[0026] like Figure 1-Figure 3 As shown, a support seat 13 is also fixed to one end of the base 14, and a secondary shaft seat 12 is provided at one end of the support seat 13. A hydraulic cylinder 11 is rotatably connected to one side of the secondary shaft seat 12, and the telescopic end of the hydraulic cylinder 11 is connected to the main shaft seat 10, and the extended end of the main shaft seat 10 is connected to the outer wall of the frame 7; specifically, the hydraulic cylinder 11 is connected to an external oil pump through a pipeline (not shown in the figure), and the oil driven by the external oil pump provides power to the hydraulic cylinder 11, so as to extend and retract. During the extension of the hydraulic cylinder 11, the telescopic end of the hydraulic cylinder 11 pushes the main shaft seat 10 upward, and the main shaft seat 10 pushes the frame 7 upward. The other end of the frame 7 rotates around the shaft body 21, and the tail end of the hydraulic cylinder 11 rotates around the secondary shaft seat 12. During the rotation of the shaft body 21, the frame 7 as a whole tilts at an angle. At this time, the top of the frame 7 is lifted upward to a higher height, and grain can be transported to a higher grain storage bin.

[0027] like Figure 1 As shown, a turntable 18 is provided at the bottom of the base 14, and a base 19 is provided at the bottom of the turntable 18; specifically, the middle part of the base 19 is a bearing structure, and the base 19 is a bearing seat structure (not shown in the figure). The bearing seat structure is a prior art and is not described here. A shaft is fixed to the bottom end of the turntable 18, and the shaft is inserted into the bearing inner liner ring in the middle of the base 19. The turntable 18 can rotate 360 ​​degrees on the base 19, so as to facilitate the adjustment of the direction of the frame 7 and facilitate the transportation of grain to different positions.

[0028] like Figure 1 As shown, a card plate 16 is also provided on the top of the turntable 18, and a counterweight block 17 is provided on one side of the card plate 16; wherein the counterweight block 17 is usually made of lead blocks, and is transported by a crane during installation and disassembly. The function of the counterweight block 17 is to stabilize the frame 7 and the mechanism installed on the frame 7 to prevent the frame 7 from tipping over.

[0029] like Figure 1 and Figure 3 As shown, a material guide plate 3 is also provided at the bottom of the feed box 2, and side bands 4 are provided on both side walls of the material guide plate 3. Both the material guide plate 3 and the side bands 4 are elastic structures.

[0030] Specifically, the grain falls into the feed box 2, and dust is generated in this process. The grain continues to move downward after passing through the feed port 1, and passes through the material guide assembly. Since the material guide plate 3 and the side band 4 are elastic, the material guide plate 3 is a curved structure, and the grain will not fall vertically downward after passing through the material guide plate 3. The grain and the dust mixed in the grain have a buffer space in the material guide assembly. In this process, the dust is sucked upward by the suction force of the vacuum cleaner 23, and passes through the dust collecting plate 24 and the hose 22, and finally enters the vacuum cleaner 23.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
