Description

Technical Field

[0001] This utility model relates to the technical field of sunflower seed shelling equipment, and in particular to a feeding and impurity removal device for a sunflower seed shelling mechanism. Background Technology

[0002] Before shelling sunflower seeds, the raw materials need to be transported from the storage tank to the shelling mechanism via the feeding mechanism, and then the subsequent shelling and screening processes are carried out. In the existing technology, a blower is often used to generate negative pressure to suck the raw materials from the storage tank into the feeding hopper at the top of the shelling mechanism. Since the raw materials of sunflower seeds contain a lot of impurities, a filter screen is set at the discharge port of the feeding mechanism to prevent impurities from entering the subsequent shelling and screening processes. However, during the process of extracting raw materials by generating negative pressure with a blower, impurities are easy to clog the filter screen, so the filter screen needs to be cleaned every few minutes, which leads to low production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a feeding and impurity removal device for a sunflower seed shelling mechanism to solve the problems existing in the prior art. It can eliminate the filter structure in the prior art and effectively separate the sunflower seed shells and impurities in the raw materials, saving time and effort and improving production efficiency.

[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides a feeding and impurity removal device for a sunflower seed shelling mechanism, including a feeding pipe and an impurity removal chamber. The feeding pipe has a discharge port located above the sunflower seed shelling mechanism. The impurity removal chamber is connected between the discharge port and the feeding hopper of the sunflower seed shelling machine. The impurity removal chamber has an air inlet and an air suction port. The air inlet and the air suction port are located on both sides of the sunflower seed discharge area in a horizontal direction. The air suction port is connected to a negative pressure component.

[0005] Preferably, the negative pressure assembly includes a dust removal mechanism and a negative pressure supply mechanism, which are sequentially connected to the air intake along the gas flow direction.

[0006] Preferably, the dust removal mechanism is a cyclone dust collector, the inlet of which is connected to the air intake, and the outlet of which is connected to the negative pressure supply mechanism.

[0007] Preferably, the air inlet is connected to an air supply mechanism that supplies air into the impurity removal cavity.

[0008] Preferably, the discharge port is arranged downward and has an elongated structure, and the discharge port extends horizontally, while the air inlet and the air suction port are distributed in a direction perpendicular to the extension of the discharge port.

[0009] Preferably, the impurity removal cavity is provided with a plurality of air inlets and a plurality of air suction ports, and each air inlet and each air suction port is equally spaced along the direction of the material discharge port.

[0010] Preferably, the air outlet of the air supply mechanism is connected in parallel with multiple air inlet pipes, each of the air inlet pipes being connected to each of the air inlets, and the inlet of the cyclone dust collector is connected in parallel with multiple suction pipes, each of the suction pipes being connected to each of the suction inlets.

[0011] Preferably, the bottom of the impurity removal cavity is provided with a discharge port that communicates with the feed hopper of the sunflower seed shelling machine, and the discharge port is located on the side of the discharge port near the air intake along the air supply direction.

[0013] Preferably, the conveying pipeline is equipped with a storage tank for storing sunflower seeds, and a bucket elevator is connected between the storage tank and the conveying pipeline.

[0014] The present invention achieves the following technical advantages over the prior art:

[0015] As the raw sunflower seeds fall from the feed inlet into the impurity removal chamber, they are evenly dispersed. The negative pressure component generates negative pressure in the impurity removal chamber through the air intake, and air is introduced at the air inlet to supplement the pressure. This allows the light impurities mixed in with the raw sunflower seeds to be directly driven into the air intake by the flowing air at the air inlet, thereby separating the light impurities from the raw sunflower seeds and achieving the initial impurity removal work.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this utility model is to provide a feeding and impurity removal device for a sunflower seed shelling mechanism to solve the problems existing in the prior art. It can eliminate the filter structure in the prior art and effectively separate the sunflower seed shells and impurities in the raw materials, saving time and effort and improving production efficiency.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 2 As shown, this embodiment provides a feeding and impurity removal device for a sunflower seed shelling mechanism, including a conveying pipe 1 and an impurity removal chamber 2. The conveying pipe 1 has a discharge port located above the sunflower seed shelling machine 7. The impurity removal chamber 2 is connected between the discharge port and the feeding hopper 9 of the sunflower seed shelling machine 7. Preferably, the conveying pipe 1 extends vertically in the opposite direction, with a discharge port at its bottom. A conveying mechanism is provided between the top of the conveying pipe 1 and a storage tank 8 for storing sunflower seeds, so as to convey the sunflower seed raw material from the storage tank 8 to the top of the conveying pipe 1, and then drop it from the discharge port, completing the work of conveying the sunflower seed raw material into the impurity removal chamber 2. The impurity removal chamber 2 has an air inlet 3 and an air suction port 4, which are located horizontally on both sides of the sunflower seed discharge area. The air vent 4 is connected to the negative pressure component 6. As the raw sunflower seeds fall from the discharge port into the impurity removal chamber 2, they are evenly dispersed. The negative pressure component 6 generates negative pressure in the impurity removal chamber 2 through the suction port 4, and the air inlet 3 provides additional pressure. This allows light impurities mixed in with the raw sunflower seeds, such as sunflower seed shells, dust, or debris, to be directly drawn into the suction port 4 by the flowing air at the air inlet 3. This separates the light impurities from the raw sunflower seeds, achieving the initial impurity removal work. It should be noted that the negative pressure generated by the negative pressure component 6 can remove the light impurities mixed in with the raw sunflower seeds without exerting an excessive attraction on the raw sunflower seeds, thus preventing the raw sunflower seeds from being sucked out of the impurity removal chamber 2 by the negative pressure component 6.

[0024] In one specific embodiment, the negative pressure component 6 includes a dust removal mechanism and a negative pressure supply mechanism. Preferably, the negative pressure supply mechanism includes a negative pressure pump, etc. The dust removal mechanism and the negative pressure supply mechanism are sequentially connected to the air intake 4 along the gas flow direction. The dust removal mechanism removes dust from the air mixed with light impurities, preventing the light impurities from affecting the negative pressure supply mechanism. Preferably, the dust removal mechanism is a cyclone dust collector. The inlet of the cyclone dust collector is connected to the air intake 4, and the outlet of the cyclone dust collector is connected to the negative pressure supply mechanism. The cyclone dust collector removes light impurities mixed in the air, and the operator periodically opens the discharge port of the cyclone dust collector to collect and process the light impurities.

[0025] In one specific embodiment, the air inlet 3 is connected to an air supply mechanism 5 that supplies air into the impurity removal chamber 2. Through the air supply mechanism 5 and the air inlet 3, air is supplied into the impurity removal chamber 2, allowing the supplied air to actively agitate the raw sunflower seeds. This causes lightweight impurities adhering to the raw sunflower seeds to detach quickly and disperses the falling seeds, ensuring that the air intake 4 can quickly remove impurities distributed within the impurity removal chamber 2. It should be noted that the air supply volume of the air supply mechanism 5 is only sufficient to agitate the raw sunflower seeds; it is insufficient to directly blow the raw sunflower seeds into the air intake 4.

[0026] Furthermore, the discharge port is set downward and has a long strip structure, and the discharge port extends in the horizontal direction. The air inlet 3 and the suction port 4 are distributed in the direction perpendicular to the extension of the discharge port. By setting the discharge port into a long strip structure, the dispersion of the raw sunflower seeds can be fully improved. Then, in conjunction with the air intake at the air inlet 3, the raw sunflower seeds are blown, thereby improving the removal efficiency of light impurities.

[0027] Furthermore, the impurity removal chamber 2 is provided with multiple air inlets 3 and multiple air suction ports 4. Each air inlet 3 and each air suction port 4 is evenly distributed along the direction of the material discharge port. By setting multiple evenly distributed air inlets 3, the scattered raw material sunflower seeds can be blown evenly, improving the efficiency of light impurities being removed from the raw material sunflower seeds, and avoiding the direct blowing of some raw material sunflower seeds into the air suction port 4 due to the concentrated setting of air inlets 3. In addition, by setting multiple evenly distributed air suction ports 4, light impurities scattered in various places in the impurity removal chamber 2 can be simultaneously adsorbed, thereby improving the impurity removal efficiency.

[0028] In one specific embodiment, the air supply mechanism 5 has multiple air inlet pipes connected in parallel at the air outlet, and each air inlet pipe is connected to each air inlet 3. The cyclone dust collector has multiple suction pipes connected in parallel at the inlet, and each suction pipe is connected to each suction port 4, thereby achieving uniform air supply volume at each air inlet 3 and uniform air suction volume at each suction port 4.

[0029] In one specific embodiment, the bottom of the impurity removal chamber 2 is provided with a discharge port that communicates with the feed hopper 9 of the sunflower seed shelling machine 7. The discharge port is located on the side of the discharge port near the suction port 4 along the air supply direction, so that there is a certain distance between the discharge port and the discharge port in the horizontal direction. On the one hand, the corresponding distance between the discharge port and the discharge port can ensure that the raw sunflower seeds can travel a certain distance in the horizontal direction under the negative pressure of the suction port 4 before falling to the discharge port, so as to fully avoid the raw sunflower seeds being sucked into the suction port 4 before falling to the discharge port. On the other hand, the corresponding distance between the discharge port and the discharge port ensures that the discharge port is on the trajectory of the raw sunflower seeds falling, avoiding the accumulation of raw sunflower seeds on one side of the discharge port, which would affect the processing efficiency of the raw sunflower seeds.

[0030] In a preferred embodiment of this utility model, a multi-stage linear vibrating screen is provided between the impurity removal chamber 2 and the sunflower seed shelling machine 7. The feed end of the first-stage linear vibrating screen is connected to the discharge port, and the discharge end of the last-stage linear vibrating screen is connected to the feed hopper 9 of the sunflower seed shelling machine 7. By setting up a linear vibrating screen for multi-stage conveying of raw sunflower seeds, the raw sunflower seeds that have already had light impurities removed are vibrated and screened layer by layer, thereby removing heavier impurities, so as to ensure that the raw sunflower seeds are thoroughly cleaned before the shelling process.

[0031] In one specific embodiment, the conveying pipeline 1 is equipped with a storage tank 8 for storing sunflower seeds. A bucket elevator 12 is connected between the storage tank 8 and the conveying pipeline 1. The bucket elevator 12 includes a main body, a feed hopper 9 fixedly connected to the side wall of the main body, and a discharge hopper 13 fixedly connected to the side of the main body away from the feed hopper 9. A base is provided below the main body of the bucket elevator 12. A discharge port 10 is opened at the bottom of the main body of the bucket elevator 12. The lower surface inside the main body of the bucket elevator 12 is fixedly... Two inclined plates 11 are fixedly connected to the discharge port 10. The ends of the two inclined plates 11 away from the inner side wall of the main body of the bucket elevator 12 extend into the discharge port 10. The raw material is fed into the main body of the bucket elevator 12 through the feed hopper 9 and comes out from the discharge hopper 13, completing the conveying of the raw material sunflower seeds. The raw material sunflower seeds that fall into the main body of the bucket elevator 12 are rolled off by the two inclined plates 11 and discharged directly to the outside of the main body of the bucket elevator 12 through the discharge port 10, so that the fallen raw material sunflower seeds can be discharged from the bucket elevator 12.
