Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of peanut screening and stone removal, in particular to peanut screening and stone removal equipment. Background Art
[0002] Peanuts are one of the main crops in northern my country and the main raw material for edible oil. At present, peanuts in northern my country are generally planted in sandy and muddy land. After the peanuts are harvested, the surface of the peanuts is generally sticky with sand. At present, the sand on the surface of the peanuts is generally removed by special machines for processing peanut sand. However, since most of these equipments use semi-mechanical operations, the peanuts are easily damaged in the process of removing the sand, resulting in some sand and gravel particles mixed in the peanut kernels when the peanuts are shelled later;
[0003] In the prior art, when the peels and sand and gravel in the peanut kernels are screened, they are generally screened by a winnowing machine. First, the color sorting device in the equipment is adjusted so that the color difference sensor in the equipment can recognize the color of the peanut kernels. Then the peanut kernels are poured into the equipment and allowed to fall naturally. During the falling process, the sensor recognizes the color of the peanut kernels and blows the peanut kernels away through the air outlet for screening. However, the working principle of this screening method is relatively complicated, and more equipment is used, which is costly and inconvenient to operate. In addition, when the peanut kernels are blown away by the air blowing structure, impurities in the same air duct as the peanut kernels will also be blown away, resulting in an unsatisfactory screening effect. Utility Model Content

[0006] As a further solution of the utility model: the diameter of the sieve holes in the stone screening area is smaller than the diameter of the sieve holes in the kernel screening area. Generally, the sand and gravel particles mixed in are smaller, which are smaller than the peanut shell impurities.
[0007] As a further solution of the utility model: a circular groove is provided on the top of the air screen frame, which fits with the outer side of the sub-screen cylinder structure and fits with the sub-screen cylinder structure to prevent debris from splashing.

[0009] As a further solution of the utility model: the screening drum structure is arranged obliquely, and a feed plate is fixed on the upper side of the base at the top of the screening drum structure for conveying unscreened peanut kernels.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The utility model provides a technical solution to solve the existing problems raised in the background technology.
[0023] Combined with Figure 1-4 It can be known that the device includes a base 1, a screening drum structure 2 is arranged above the base 1, and the side of the screening drum structure 2 is divided into a stone screening area 2.1 and a kernel screening area 2.2, which can screen sand and peanut kernels, and the kernel screening area 2.2 can screen smaller peanut kernels and small pieces of peanut shells. A wind screen structure is placed above the base 1 at the kernel screening area 2.2, and the wind screen structure includes a wind screen frame 3, and a debris outlet 3.1 is opened on one side of the wind screen frame 3, and a material outlet 3.2 is opened on the other side of the wind screen frame 3 near the bottom, and a fixed A wind selection frame 3.3 is provided with a connecting port 3.4 on one side of the wind selection frame 3.3, and an air outlet 3.5 on the other side of the wind selection frame 3.3, so that the falling peanut kernels can be blown with air. A folding plate 3.6 is fixed on the inner side of the wind screen frame 3 at the outlet 3.1. Since the peanut kernels are heavier than the peanut shells, the lighter peanut shells will fall on the top of the folding plate 3.6 after being blown by the air, while the heavier peanut kernels will be blown but not blown away. A discharge plate 3.7 is fixed on one side of the wind screen frame 3 below the discharge port 3.2, and the bottom surface of the wind screen frame 3 is inclined toward the discharge port 3.2.
[0024] The diameter of the sieve holes in the stone screening area 2.1 is smaller than that in the kernel screening area 2.2. Generally, the sand and gravel particles mixed in are smaller, which are smaller than the impurities in the peanut shells. A circular groove 3.8 is provided on the top of the air screen frame 3 to fit with the outer side of the sub-screening cylinder structure 2, and fit with the sub-screening cylinder structure 2 to prevent the splashing of debris. A miscellaneous material box 4 is placed on the upper side of the base 1 below the stone screening area 2.1 to collect stones and debris. The sub-screening cylinder structure 2 is arranged obliquely, and a feed plate 5 is fixed on the upper side of the base 1 at the top of the sub-screening cylinder structure 2 to transport the unscreened peanuts. Limiting rings 2.3 are fixed at both ends of the outer side of the sub-screening drum structure 2, and an articulated seat 6 is fixed on the upper side of the base 1 at the limiting ring 2.3. A roller 7 is rotatably connected to the top of the articulated seat 6, and the side of the roller 7 is in contact with the limiting ring 2.3. A transmission motor 8 is fixed to one side of the articulated seat 6, and the output end of the transmission motor 8 is fixed to one side of the roller 7. The rotation of the roller 7 can drive the sub-screening drum structure 2 to roll through the limiting ring 2.3; the transmission motor 8 is electrically connected to an external power supply, and the connecting port 3.4 is connected to an external air compressor.
[0025] The working principle of the present application is as follows: when screening peanuts, first start the transmission motor 8 to drive the roller 7 to rotate, so as to drive the screening drum structure 2 to roll, and then pour the unscreened peanut kernels from the feed plate 5 into the screening drum structure 2, and the smaller sand and gravel in the peanut kernels will be screened out through the stone screening area 2.1 and fall into the miscellaneous material box 4 for collection. As the peanut kernels move, they will gradually come to the kernel screening area 2.2, and the kernel screening area 2.2 will screen out the smaller peanut kernels and smaller peanut shell fragments, and then as they fall, the wind blown out through the air outlet 3.5 will blow the peanut shells onto the folding plate 3.6 and be discharged from the miscellaneous outlet 3.1, while the peanut kernels will be output through the discharge plate 3.7, and finally the larger peanut kernels and larger peanut shells will be output from the bottom end of the screening drum structure 2. Generally, there are fewer larger peanut shells, which can be screened by manual picking.
[0026] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
