A screening and dust removal machine for producing sunflower seeds

Abstract

This utility model relates to the field of sunflower seed production technology, and discloses a screening and dust removal machine for producing sunflower seeds. The machine includes a screening body and a feeding section installed above it. The feeding section includes: a feeding hopper, which is bolted to the left side of the top of the screening body; guide plates are fixed on both sides of the inner cavity of the feeding hopper, and both guide plates are inclined; and a buffer component installed inside the feeding hopper and located below the guide plates on both sides. When sunflower seeds fall into the feeding hopper, they fall between adjacent buffer plates. The weight of the seeds causes the buffer plates to rotate, which not only controls the amount of seeds falling but also reduces the impact of the seeds directly on the screen inside the screening body, preventing the scattering of seed shells. Simultaneously, the rotation of the movable disc allows the movable plate to reciprocate through a force-applying component, enabling the dispersing rod to break up the seeds, thus improving the subsequent screening and dust removal effect.

Description

Technical Field

[0001] This utility model relates to the field of sunflower seed production technology, specifically to a screening and dust removal machine for sunflower seed production. Background Technology

[0002] Melon seeds are the seeds of melons, specifically referring to roasted seeds of pumpkins, watermelons, etc., used for food. They are also called melon seeds or, colloquially, "side fruits." There are many varieties, including sunflower seeds, sea melon seeds, hanging melon seeds, watermelon seeds, pumpkin seeds, cucumber seeds, and loofah seeds. Sunflower seeds are the fruit of the sunflower and can be eaten as a snack, used as an ingredient in pastries, and are also an important source of oil, a high-quality and healthy source of oil. Sea melon seeds are a specialty of the sea, characterized by their tender and refreshing taste. Roasted white melon seeds can be eaten directly or seasoned to make flavored melon seeds with a delicious aroma.

[0003] Before roasting, sunflower seeds often need to be screened and dust removed using a vibrating screener. However, current vibrating screeners simply pour the sunflower seeds into the feed hopper, and then a large number of seeds fall into the screening machine. The seeds are then screened and dust removed by vibration. When the seeds fall into the screening machine, a large number of seeds tend to accumulate, which affects the effectiveness of subsequent screening and dust removal. Utility Model Content

[0004] The purpose of this utility model is to provide a screening and dust removal machine for producing sunflower seeds, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening and dust removal machine for producing sunflower seeds, comprising a screening machine body and a feeding section installed above it, wherein the feeding section includes: The feed hopper is fixed to the left side of the top of the screening machine body by bolts. Guide plates are fixed on both sides of the inner cavity of the feed hopper, and the guide plates on both sides are inclined. A buffer is installed inside the feed hopper and located below the two side guide plates. The guide plates guide the falling sunflower seeds, and the weight of the sunflower seeds is used to make the buffer rotate. Evacuation components are installed on the top of the screening machine body and located on one side of the feed hopper; The buffer component achieves reciprocating motion of the evacuation component through rotation.

[0006] Preferably, the buffer includes: A rotating rod is rotatably connected to the inside of the feed hopper, with one end penetrating the feed hopper and extending to the outer surface of the feed hopper; The buffer plate is arc-shaped and is fixed around the surface of the rotating rod; Among them, the included angle between two adjacent buffer plates is greater than the distance between two adjacent guide plates; The movable disc is fixed to one end of the rotating rod and located in front of the feed hopper.

[0007] Preferably, the evacuation component includes: A fixed plate is fixed to both sides of the top of the screening machine body, and a movable plate slides through the inside of the fixed plate; The evacuation rods are vertical at the top and circular at the bottom, and are fixed at equal intervals to the bottom of the movable plate.

[0008] The force-applying component is located on one side of the feed hopper and is used in conjunction with the movable disc.

[0009] Preferably, the force-applying component includes: The support plate is folded, with one end fixed to one side of the fixed plate mentioned above, and a movable plate passing through the interior of the other end; The push plate has one end rotatably connected to the surface of the movable plate, and the other end rotatably connected to one end of the moving plate. The connecting plate is rotatably connected at one end to the top of the movable plate, and rotatably connected at the other end to the other end of the movable plate.

[0010] Preferably, the moving plate slides through the support plate for a distance less than the distance between the outermost evacuation rod and the inner wall of the screening machine body.

[0011] Preferably, a limit plate is fixed at one end of the movable plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When sunflower seeds fall into the hopper, they fall between adjacent buffer plates. The weight of the sunflower seeds causes the buffer plates to rotate, which not only controls the amount of sunflower seeds falling, but also reduces the impact of sunflower seeds directly on the screen inside the screening machine, thus reducing the splashing of sunflower seed shells. At the same time, the rotation of the movable plate can also drive the movable plate to move back and forth through the force application component, so that the dispersing rod can break up the sunflower seeds, thereby improving the effect of subsequent screening and dust removal.

Detailed Implementation

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] Please see Figure 1-5 As shown, a screening and dust removal machine for producing sunflower seeds includes a screening machine body 100 and a feeding section 200 installed above it. The feeding section 200 includes a feeding hopper 210 fixed to the top left side of the screening machine body 100 by bolts. Guide plates 211 are fixed on both sides of the inner cavity of the feeding hopper 210, and both guide plates 211 are inclined. Because the guide plates 211 are inclined, they can guide the sunflower seeds falling in, so as to facilitate the falling. A buffer member 220 is installed inside the feeding hopper 210 and below the two guide plates 211. See attached drawing. Figure 4 To reduce the rate of sunflower seed feeding, the buffer component 220 includes a rotating rod 221 rotatably connected inside the feed hopper 210. One end of the rotating rod 221 passes through the outer surface of the feed hopper 210 and is fixed with a movable disc 223. Several buffer plates 222 are fixed around the surface of the rotating rod 221 in an arc shape. The included angle between two adjacent buffer plates 222 is greater than the distance between two adjacent guide plates 211.

[0017] When the sunflower seeds fall into the feed hopper 210, they are guided by the guide plate 211 and fall between the adjacent buffer plates 222. As the buffer plates 222 are arranged in an arc shape, the rotating rod 221 will rotate in one direction until the sunflower seeds fall onto the screen of the screening machine body 100. After the guide plate 211 guides the falling sunflower seeds, the weight of the sunflower seeds is used to make the buffer 220 rotate. The top of the screening machine body 100 and one side of the feed hopper 210 is equipped with a evacuation component 230. The buffer 220 rotates to make the evacuation component 230 reciprocate.

[0018] The screening machine body 100 is existing technology, which can remove dust and screen impurities in sunflower seeds through vibration screening. Therefore, this solution does not describe it in detail.

[0019] Based on the above scheme, see Figure 4 The system disperses the sunflower seeds. The dispersion component 230 includes a fixed plate 231 fixed to both sides of the top of the screening machine body 100. A movable plate 232 slides through the inside of the fixed plate 231. A limit plate 2345 is fixed to one end of the movable plate 232 so that the movable plate 232 will not slide out of the inside of the fixed plate 231 when it moves. Several dispersion rods 233 are fixed to the bottom of the movable plate 232. The upper end of the rods is vertical and the bottom is round. A force-applying component 234 is provided on one side of the feed hopper 210. The force-applying component 234 works in conjunction with the movable disc 223. As the movable disc 223 rotates, the force-applying component 234 will drive the movable plate 232 to move back and forth, so that the dispersion rods 233 disperse the sunflower seeds.

[0020] Based on the above scheme, the force-applying component 234 includes a support plate 2341 with one end fixed to one side of the front fixed plate 231. This support plate 2341 is folded. A movable plate 2342 passes through the interior of the other end of the support plate 2341. The sliding distance of the movable plate 2342 within the support plate 2341 is less than the distance between the outermost evacuation rod 233 and the inner wall of the screening machine body 100. Thus, when the movable plate 232 is pushed, the evacuation rod 233 will not collide with the inner wall of the screening machine body 100. A push plate 2343 is rotatably connected to the protruding part of the surface of the movable disc 223. As the movable plate 223 rotates, when the protrusion at one end of the movable plate 223 rotates to the right, it will apply force to the push plate 2343 to the right and push the moving plate 2342 to the right. This will cause the connecting plate 2344 to be subjected to force, which will push the movable plate 232 to the rear and drive the force-applying component 234 to disperse the sunflower seeds. The other end of the push plate 2343 is rotatably connected to one end of the moving plate 2342. The top of the movable plate 232 is rotatably connected to the connecting plate 2344, and the other end of the connecting plate 2344 is rotatably connected to the other end of the moving plate 2342.

[0021] Working principle: When in use, start the screening machine body 100, then pour sunflower seeds into the screening machine body 100. The seeds are then guided by the guide plate 211, causing them to fall between adjacent buffer plates 222. Because the buffer plates 222 are arc-shaped, the seeds will rotate in one direction after falling between them. As the rotating rod 221 drives the buffer plates 222 to rotate, not only is the amount of sunflower seeds falling controlled, but the impact of the seeds directly on the screen inside the screening machine body 100, preventing the seed shells from flying everywhere, is also controlled. Furthermore, as the movable disc 223 rotates, when the movable disc... When the protrusion at one end of 223 rotates to the right, it applies force to the push plate 2343 to the right and pushes the moving plate 2342 to the right. This causes the connecting plate 2344 to be subjected to force, which in turn pushes the movable plate 232 to the rear and drives the force-applying component 234 to disperse the sunflower seeds. When the protrusion at one end of the movable plate 223 rotates to the starting position, it pulls the moving plate 2342 again, causing the movable plate 232 and the force-applying component 234 to slide forward. This process is repeated to further improve the dispersion of sunflower seeds, so that the screening machine body 100 can screen and remove impurities from the sunflower seeds.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
