Description

Technical Field

[0001] The invention belongs to the technical field of grain scrapers, and in particular relates to a grain scraper device for storing grain. Background Art

[0002] The mobile wing wheel grain scraper is a bulk grain grabbing equipment, which is suitable for large and medium-sized grain depots, small grain stations and individual industrial and commercial households to scrape grain for bag filling operations, or it can be used in conjunction with other conveying machinery to form an assembly line operation.

[0003] For example, Chinese utility model CN202220141522.3 discloses a double-wing wheel grain scraper, which includes fixing and welding the scraping wings to the lower end of the connecting turntable, and fixing and welding reinforcing ridges between the plates of the scraping wings, so that the reinforced wing wheel is more solid. When rotating to scrape the materials, the scraping wings will not break due to the large amount of scraping materials. At the same time, scraping plate heads are fixedly arranged at both ends of the baffle plate, so that the reinforced wing wheel can scrape the grain materials well when rotating, thereby improving the scraping effect.

[0004] However, the impeller of the above technical solution is in the process of circular rotation. Therefore, when the scraping wing rotates from the inside to the outside, it is easy to bring part of the grain inside the material guide cover out of the material guide cover, thereby affecting the overall grain scraping effect and efficiency.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] Example 1

[0031] See also Figure 1 As shown, the present invention is a grain scraping device for storing grain, comprising a grain scraping box 1, two wing wheel scraping mechanisms rotatably connected to the grain scraping box 1, and a driving device 101 fixedly connected to the top wall of the grain scraping box 1 for driving the wing wheel scraping mechanisms. The wing wheel scraping mechanism comprises a shaft sleeve 2 fixedly connected to the inner top wall of the grain scraping box 1, and a rotating shaft 3 rotatably connected to the inner wall of the shaft sleeve 2, and the upper end of the rotating shaft 3 is transmission-connected to the driving device 101. A flange structure is provided at the upper end of the shaft sleeve 2, and a connecting hole is opened in the flange structure, so that screws can connect the shaft sleeve 2 to the inner top wall of the grain scraping box 1.

[0032] like Figures 3 to 7 As shown, the outer wall of the sleeve 2 is welded or screwed with an end cam 21, and is rotatably connected to a circular ring plate 201, and guide rods 202 are evenly distributed on the circumference of the lower surface of the circular ring plate 201; the guide rods 202 are sequentially sleeved with a spring 203 and a guide sleeve 204 from top to bottom, and the outer wall of the guide sleeve 204 is fixedly connected to a cross bar 205 that cooperates with the end cam 21.

[0033] Specifically, the working surface of the upper end of the end cam 21 includes two end surfaces of different heights. The upper end of the spring 203 abuts against the lower surface of the annular plate 201, and the lower end abuts against the guide sleeve 204, so that the cross bar 205 always remains in close contact with the working surface of the end cam 21.

[0034] The guide rod 202 is a round rod or a regular prism structure, and the inner wall of the guide sleeve 204 is adapted to the guide rod 202. In addition, the cross bar 205 is rotatably connected to a roller, which is used to cooperate with the working surface of the end cam 21 through the roller, thereby preventing the cross bar 205 and the working surface of the end cam 21 from sliding and causing wear.

[0035] The lower end of the rotating shaft 3 is hinged with a stripping plate 301 corresponding to the guide rod 202, and the upper side of the stripping plate 301 is hinged with a connecting rod 302, and the upper end of the connecting rod 302 is hinged with the cross bar 205, which is used to drive the stripping plate 301 to rotate through the rotating shaft 3, and drive the annular plate 201 to rotate through the connecting rod 302. When the stripping plate 301 rotates from the inside to the outside, the cross bar 205 cooperates with the end face cam 21 to increase the height of the guide sleeve 204, and the stripping plate 301 is pulled upward by the connecting rod 302, so that the lower surface of the stripping plate 301 is separated from the inner bottom surface of the stripping plate 301.

[0036] Specifically, when the rotating shaft 3 rotates, it drives the stripping plate 301 to rotate, and the stripping plate 301 drives the annular plate 201 to rotate through the connecting rod 302, so that the guide sleeves 204 on each guide rod 202 revolve along the shaft sleeve 2, that is, the cross bar 205 at the upper end of each guide sleeve 204 moves along the working surface of the end face cam 21.

[0037] When the scraping plate 301 rotates outside the grain scraping box 1 and grain scraping is required, the cross bar 205 is located on the working surface with a lower height of the end face cam 21, and the lower surface of the scraping plate 301 is close to or in contact with the bottom wall of the grain scraping box 1. As the rotating shaft 3 drives the scraping plate 301 to rotate, the grain is brought into the grain scraping box 1.

[0038] When the stripping plate 301 rotates into the grain stripping box 1 and rotates from the inside to the outside, at this time, the cross bar 205 moves to the working surface with a higher height of the end face cam 21, so that the guide sleeve 204 moves upward along the guide rod 202, and the connecting rod 302 is used to pull the stripping plate 301 upward, so that the lower surface of the stripping plate 301 is separated from the inner bottom surface of the stripping plate 301, so that the stripping plate 301 does not contact the grain when moving toward the outside, avoiding the situation where the stripping plate 301 brings out the grain when rotating from the inside of the grain stripping box 1 to the outside, thereby effectively improving the grain stripping effect and efficiency.

[0039] At the same time, a number of reinforcing ribs are welded to the side of the wing 304, and the reinforcing ribs are arranged in a crisscross pattern, so that the reinforcing ribs improve the overall structural strength of the wing 304 and prevent the wing 304 from bending and deforming due to stress.

[0040] Example 2

[0041] Based on the first embodiment, Figure 4 and 5 As shown, the stripping plate 301 includes a fixing rod 303 and a wing 304 fixedly connected to the fixing rod 303. The wing 304 and the fixing rod 303 can be connected by bolts, which makes it easy to disassemble and replace the wing 304.

[0042] Specifically, a mounting groove can be opened on the lower side of the fixing rod 303, and a through hole can be opened on the side of the fixing rod 303, and a connecting hole can be opened on the upper edge of the wing 304. During installation, the upper edge of the wing 304 is inserted into the mounting groove, and the connection hole and the through hole are made to correspond in position, and then the bolts are used to lock them to achieve the installation connection between the wing 304 and the fixing rod 303.

[0043] The lower end of the rotating shaft 3 extends from the shaft sleeve 2 and is fixedly connected to a rotating disk 305. One end of the fixing rod 303 is hinged to the upper surface of the rotating disk 305. The rotating disk 305 also has a circumferential surface formed with a retaining groove 306 that engages with the flap 304. This allows the stripping plate 301 to be positioned outside the stripping box 1. During stripping, the flap 304 engages with the retaining groove 306, directly applying force to the flap 304 through the rotating disk 305 to rotate and strip the grain. This improves the structural stability and reliability of the flap 304 during the stripping process.

[0044] At the same time, if Figure 3 and 7 As shown in US, the outer wall of the sleeve 2 is rotatably connected to a fixing ring 206, which is located below the circular ring plate 201 and below the working level of the end cam 21. The upper surface of the fixing ring 206 is fixedly connected to the lower end of the guide rod 202, so that the guide rod 202 is fixed between the fixing ring 206 and the circular ring plate 201, thereby improving the structural stability of the guide rod 202, which is beneficial to improving the overall structural stability and reliability of use.
