Description

Technical Field

[0001] This utility model belongs to the technical field of grain storage equipment, and relates to a grain leveling machine. Background Technology

[0002] When grain is conveyed into the grain silos via conveyor belts, it forms small piles on the surface. After all the silos are full, the grain surface needs to be leveled. After rough leveling, a scraper is used for fine leveling, which is very labor-intensive and has high labor costs.

[0003] Chinese utility model patent CN221318439U (publication date: 2024-07-12) discloses a grain surface shaping device, including a pallet pulled by manpower. The bottom of the pallet is a flat surface, and a plurality of flat teeth are arranged at intervals on the flat surface. The tips of the flat teeth are arranged downwards. A motor-driven vibrator is arranged above the pallet, and the vibration generated by the vibrator is transmitted to the flat surface and the flat teeth through the pallet.

[0004] The above-mentioned grain surface shaping device can greatly save labor costs, but its shaping effect is still not good, especially for larger pits, it is difficult to flatten or fill them by the action of the flat surface and flat teeth. Utility Model Content

[0010] In the aforementioned grain leveling machine, the connecting plate is further described as an L-shaped folded plate, and the mounting surface of the connecting plate perpendicular to the connecting pipe is provided with a mounting through hole. The flat plate is provided with a strip-shaped through hole. The fastener passes through the mounting through hole and the strip-shaped through hole and fixes the connecting plate and the flat plate. The upper end of the flat plate is bent successively to form a rear folded plate, and the rear folded plate abuts against the upper end of the connecting plate to form a positioning structure.

[0011] In the aforementioned grain leveling machine, pull rings are respectively provided on the left and right sides of the rectangular outer frame, and the pull rings are fixedly connected to the pull rope that drives the grain leveling machine.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] 1. This utility model provides a grain leveling machine, which applies pressure to the leveler through a counterweight, so that the leveler can better contact the grain surface. The grain surface is leveled through three processes: initial leveling, scraping and re-leveling, by the front leveling pipe, the leveling plate and the rear leveling pipe, thereby achieving full leveling of the grain surface.

[0016] 2. This utility model provides a series of adjustable structures: the leveling plate can be replaced with different specifications, the counterweights in the counterweight device can be selected in different quantities and masses, and a vibrator can also be installed in the counterweight device.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 :

[0025] A grain leveling machine includes a leveler and a pair of counterweights. The counterweights are respectively disposed at the left and right ends of the leveler. The leveler is provided with a front leveling pipe, a leveling plate and a rear leveling pipe in sequence from front to back. The bottom of the front leveling pipe, the leveling plate and the rear leveling pipe are in contact with the grain stacking plane. The leveling plate is inclined forward from top to bottom.

[0026] The leveling process in this embodiment is as follows: Through the force of the counterweight, the front leveling tube, leveling plate, and rear leveling tube of the leveler are all pressed against the grain surface to be leveled. Counterweights are set at both ends of the leveler to make the force more even. When the leveler is pulled forward, the front leveling tube first acts on the grain surface to be leveled to perform preliminary leveling. Then the leveling plate acts on the grain surface after preliminary leveling to scrape the grain surface, especially effectively scraping the grain pile. Finally, the rear leveling tube acts on the scraped grain surface to evenly fill the grain pit with the scraped grain. Therefore, the front leveling tube, leveling plate, and rear leveling tube sequentially perform preliminary leveling, scraping, and re-leveling on the grain surface to be leveled. Through three leveling processes, the grain surface is fully leveled.

[0027] Comparison Appendix Figure 1 and attached Figure 2 In this embodiment, the specific structure of the leveler is as follows: the leveler includes a rectangular outer frame, the front frame of the rectangular outer frame forms a front leveling tube, the rear frame forms a rear leveling tube, and a horizontally distributed connecting tube is provided in the middle of the rectangular outer frame. The leveling plate is installed obliquely on the front side of the connecting tube. Preferably, the rectangular outer frame is integrally bent from a single pipe, and the connecting tube is welded to the inner side of the rectangular outer frame. Preferably, the diameter of the connecting tube is smaller than the diameter of the rectangular outer frame, and a gap is left between the connecting tube and the grain surface when leveling the grain surface.

[0028] Comparison Appendix Figure 2 and attached Figure 4In this embodiment, the specific structure of the flat plate is as follows: several connecting plates are welded to the front side of the connecting pipe, and the flat plate is detachably mounted on the connecting plates by several fasteners. The flat plate can be replaced when necessary. Furthermore, the connecting plate is an L-shaped folded plate, and a mounting through hole is provided on the mounting surface of the connecting plate perpendicular to the connecting pipe. A strip-shaped through hole is provided on the flat plate. The fasteners pass through the mounting through hole and the strip-shaped through hole to fix the connecting plate and the flat plate. The upper end of the flat plate is bent successively to form a rear folded plate, which abuts against the upper end of the connecting plate to form a positioning structure. The fasteners include fastening bolts and fastening nuts.

[0029] Conventionally, in this embodiment, the machine is pulled manually. To facilitate pulling the grain leveler, pull rings are provided on the left and right sides of the rectangular outer frame, and the pull rings are fixedly connected to the pull rope that drives the grain leveler.

[0030] Comparison Appendix Figure 5 In this embodiment, the counterweight includes a counterweight box with a counterweight cover plate hinged to it. A plurality of counterweight mounting posts are provided inside the counterweight box, and a plurality of counterweight blocks can be selectively mounted on each mounting post. Further, each counterweight mounting post is a screw rod, and a nut for fixing the counterweight blocks is screwed onto the screw rod. Each counterweight block has a through hole that mates with the screw rod. The required number of counterweight blocks are sequentially mounted on the screw rod, and then the counterweight blocks are fixed by the nut.

[0031] Furthermore, a vibrator is installed inside the counterweight box; the counterweight box has a reserved installation position for the vibrator. Specifically, a counterweight block is installed on the outside of the counterweight box, and a vibrator is installed on the inside. By using the vibrator to vibrate the grain surface, the shaped grain surface can be made smoother.

[0032] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
