Description

Technical Field

[0001] The present invention relates to the field of corn seed treatment, and particularly to a new type of corn seed coating machine. Background Art

[0002] The current design of corn seed coating machines involves feeding and discharging, mixing water and materials with corn seeds, and then drying to form corn seed coatings. However, current traditional coating equipment includes drum-type, vertical stirring-type, spray-type, and centrifugal coating machines. Most of the existing coating machines occupy a large area. The corn seeds are continuously processed through multiple processes inside, making the operation of multiple processes often time-consuming and the overall efficiency not high. Based on this, this solution proposes an efficient coating equipment based on gravity self-falling to solve the above problems;

[0003] Compared with other types of corn seeds, corn seeds have irregular shapes and are extremely prone to uneven coating. In addition, the surface of corn seeds is relatively smoother, and the adhesion of the coating agent to corn seeds is not as good as that of some corn seeds with rough surfaces. There is a situation of mutual friction between corn seeds in the traditional method, making it extremely prone to local coating peeling after coating. Summary of the Invention

[0004] The purpose of the present invention is to propose a new type of corn seed coating machine to solve the problems of long time consumption and low efficiency in the continuous processing of multiple processes by existing traditional corn seed coating machines, as well as uneven coating or local peeling of corn seeds.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: A new type of corn seed coating machine includes a vertical frame and a separation component and a liquid supply component installed thereon, and further includes:

[0006] A coating component, which is connected to a material distributor for uniform feeding at the top, includes an intermittent cover connected to the separation component, and a plurality of flat nozzles symmetrically arranged in the intermittent cover and connected to the liquid supply component;

[0007] A support base, which includes an aggregate box fixed to the intermittent cover, and an intermittent hopper fixed to the inner wall of the aggregate box for receiving materials at the bottom of the intermittent cover;

[0008] A drying module, which includes a discharge component connected to the bottom of the intermittent cover, and a hot air generating component connected to the bottom of the discharge component. A driver for driving the hot air generating component is arranged on one side of the hot air generating component;

[0009] The discharge component includes an inclined guide groove and a rubber adapter connected between it and the intermittent cover. Buffer covers connected to the hot air generator are symmetrically installed on both sides of the inclined guide groove. A reduction gear set for driving the material distributor is installed on one side of the driver;

[0010] The hot air generating assembly generates rising hot air currents to dry the corn seeds passing through the coating assembly and separate the impurities of the corn seeds that do not pass through the coating assembly. At the same time, the excess water and material are attached to the inner wall of the intermittent cover under the action of the air flow lift force and then pass through the intermittent hopper in a staggered manner and enter the aggregate box for recycling.

[0011] As a further description of the above technical solution: The separation assembly includes a dust removal pipe that is inclined and communicated with the top end of the intermittent cover. The bottom end of the dust removal pipe is communicated with a storage box. A filter plate is fixedly arranged on the inner wall of the storage box in an inclined shape, and a sewage discharge valve for cleaning is arranged at the bottom of the storage box.

[0012] As a further description of the above technical solution: The liquid supply assembly includes a liquid storage tank with a liquid supplement function. A pump body is installed on the liquid storage tank and is communicated with its interior. A return pipe for the water and material to flow back and communicated with the aggregate box is also installed on it.

[0013] As a further description of the above technical solution: The coating assembly further includes two shunt pipes communicated with the pump body, and a number of flat nozzles are jointly communicated with the shunt pipe on the same side.

[0014] As a further description of the above technical solution: The material distributor includes a material distribution bin communicated with the top end of the intermittent cover. A material distribution wheel driven by a speed reduction wheel set rotates through the inner wall of the material distribution bin. A hopper is installed at the top end of the material distribution bin.

[0015] As a further description of the above technical solution: The hot air generating assembly includes a pressurizing hopper. A fan blade is rotatably installed on the inner wall of the pressurizing hopper. One end of the fan blade is fixed to the output shaft of the driver. An electric heating wire is installed at the air inlet of the pressurizing hopper.

[0016] As a further description of the above technical solution: The speed reduction wheel set is two belt wheels with different diameters and are respectively fixed on the driving ends of the driver and the material distribution wheel, so that there is a constant speed difference between the material distribution wheel and the fan blade.

[0017] As a further description of the above technical solution: The discharging assembly further includes an air path tee communicated with two slow flow covers, and one end of the air path tee is communicated with the air outlet of the pressurizing hopper.

[0018] As a further description of the above technical solution: Left and right trusses are respectively fixed on both sides of the aggregate box, and both the left truss and the right truss are fixed on the vertical frame. The storage box is fixedly penetrated on the right truss.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] In this solution, a material distributor is used to keep the corn seeds in a state of constant density, uniformly and continuously falling freely. At the same time, a hot air generating component generates an air current in the opposite direction to the material falling. This air current intersects with the corn seeds that have just entered the top of the intermittent cover, and carries the corn seed debris and other impurities into the separation component through the carrying action of the air current. The impurities are stored for unified discharge. At the same time, after the corn seeds after impurity removal pass through the coating on the surface of the flat nozzle, they are quickly dried under the action of the reverse hot air current. At the same time, based on the obliquely downward spraying angle, a large amount of the sprayed water material adheres to the intermittent cover, and a small amount of the splashed water material cannot fall vertically under the action of the reverse air current. After falling at a certain slope, it adheres to the inner wall of the intermittent cover and enters the aggregate box as it falls, so that it can be recycled by the liquid supply component. This method adopts a rapid and uniform coating mechanism for the vertical falling of corn seeds, avoiding repeated mutual friction and stirring between corn seeds and resulting in coating damage. Overall, it realizes the continuous processing of drying corn seeds, separating impurities, and fully coating with a large flow of water material and then recycling. The overall coating quality and efficiency have been greatly improved;

[0021] This solution can avoid the mutual friction of corn seeds, solve the problems of uneven coating and local peeling of corn seeds, and ensure the integrity and uniformity of the coating. Brief Description of the Drawings

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] As Figure 1 - Figure 11 shown, the present invention provides: a new type of corn seed coating machine, including an upright frame 10 and a separation component 60 and a liquid supply component 70 installed thereon, and further including:

[0043] The design of the separation component 60 facilitates impurity cleaning. The impurity removal pipe 63 is communicated with the top of the intermittent cover 41. The impurities enter the storage box 61 along with the air flow. The inclined filter plate 62 in the storage box 61 facilitates the falling of impurities. The drain valve 64 at the bottom can realize the unified cleaning of impurities, ensuring the cleanliness of the coating environment and avoiding the influence of impurities on the coating quality;

[0044] At the top of the coating component 40, a material leveling device 30 for uniform material feeding is connected. The material leveling device 30 includes an intermittent cover 41 connected to the separation component 60, and a number of flat nozzles 42 symmetrically arranged in the intermittent cover 41 and connected to the liquid supply component 70;

[0045] By setting the intermittent cover 41 and the flat nozzles 42 therein, when the internal corn seeds fall, they can contact the water material (the coating on the surface of the corn seeds, hereinafter collectively referred to as water material) to complete the coating. The staggered layout of the flat nozzles 42 can ensure sufficient coating.

[0046] The support base 20 includes an aggregate box 21 fixed to the intermittent cover 41, and an intermittent hopper 22 for receiving materials at the bottom of the intermittent cover 41 is fixed to the inner wall of the aggregate box 21;

[0047] The drying module 50 includes a discharge component 54 connected to the bottom of the intermittent cover 41, and a hot air generating component 53 is connected to the bottom of the discharge component 54. A driver 51 for driving the hot air generating component 53 is arranged on one side of the hot air generating component 53;

[0048] The discharge component 54 includes an inclined guide groove 541 and a rubber adapter 542 connected between the inclined guide groove 541 and the intermittent cover 41. Flow retarder covers 543 connected to the hot air generator are symmetrically installed on both sides of the inclined guide groove 541. A reduction gear set 52 for driving the material leveling device 30 is installed on one side of the driver 51;

[0049] The shapes of corn seeds are irregular and their surfaces are smooth. Traditional coating methods are prone to causing friction between corn seeds, resulting in coating breakage. However, the coating method of the corn seeds falling vertically is adopted in this solution. While improving the coating efficiency, it avoids repeated friction and stirring between corn seeds. This design fundamentally eliminates this problem, ensures the integrity of the coating, and improves the quality of the coating of corn seeds;

[0050] At the same time, the material leveling device 30 enables the corn seeds to fall freely continuously and uniformly at a constant density. Cooperating with the flat nozzles 42 symmetrically and staggeredly arranged in the intermittent cover 41, the corn seeds can fully contact the coating water material during the falling process, solving the problem of uneven coating that is prone to occur due to the irregular shape of the corn seeds, and ensuring that each corn seed can be evenly coated;

[0051] At the same time, most of the sprayed water material adheres to the intermittent cover 41. A small amount of splashed water material adheres to the inner wall of the intermittent cover 41 under the action of the reverse air flow and then enters the aggregate box 21, and is recycled by the reflux liquid supply component 70. On the premise of ensuring sufficient coating with large-flow spraying, the waste of the coating water material is reduced, and the production cost is lowered;

[0052] The hot air generating assembly 53 generates rising hot air currents to dry the corn seeds passing through the coating assembly 40 and separate the impurities of the corn seeds that do not pass through the coating assembly 40. At the same time, the excess water and material are attached to the inner wall of the intermittent hood 41 under the action of the air flow lift force and then misaligned through the intermittent hopper 22 into the aggregate box 21 for recycling.

[0053] Specifically, as Figure 3 shown: The separation assembly 60 includes an impurity removal pipe 63 that is inclined and connected to the top end of the intermittent hood 41. The bottom end of the impurity removal pipe 63 is connected to a storage box 61. A filter plate 62 is fixedly installed on the inner wall of the storage box 61 in an inclined shape, and a sewage discharge valve 64 for cleaning is provided at the bottom of the storage box 61.

[0054] By setting the separation assembly 60, the storage box 61 included therein allows the air flow and impurities to enter together through the impurity removal pipe 63. At the same time, the air is discharged through the filter plate 62, and the impurities are retained in the storage box 61. The filter plate 62 is inclined, which can facilitate the dropping of impurities, and the impurities are uniformly cleaned through the sewage discharge valve 64.

[0055] Specifically, as Figure 3 shown: The liquid supply assembly 70 includes a liquid storage tank 71 with a liquid replenishment function. A pump body 72 is installed on the liquid storage tank 71 and is connected to its interior. A return pipe 73 for the water and material to flow back and connected to the aggregate box 21 is also installed thereon.

[0056] By setting the liquid storage tank 71 and the return pipe 73 provided thereon, the water and material in the storage box 61 can be guided back to the liquid storage tank 71. A threaded cover is also provided on the liquid storage tank 71, which can facilitate the liquid replenishment operation.

[0057] Specifically, as Figure 2 and Figure 11 shown: The coating assembly 40 further includes two shunt pipes 43 connected to the pump body 72, and a number of flat nozzles 42 are commonly connected to the shunt pipe 43 on the same side.

[0058] By setting the pump body 72, the pump body 72 can keep transporting and pressurizing the water and material, so that the flat nozzles 42 have pressure. The pressure of the pump body 72 for transporting the water and material is kept constant. The two flat nozzles 42 at different heights on the left and right are staggered, and the upper and lower two flat nozzles 42 on the same side are also staggered, so that the corn seeds falling in free fall can be fully contacted with the water and material in different directions.

[0059] Specifically, as Figure 6 and Figure 8 shown: The material distributor 30 includes a material distribution bin 31 connected to the top end of the intermittent hood 41. A material distribution wheel 33 driven by a reduction gear set 52 rotates through the inner wall of the material distribution bin 31, and a hopper 32 is installed at the top end of the material distribution bin 31.

[0060] By setting a material leveling wheel 33, the surface of which has multiple protrusions, the corn seeds can be gradually fed at a constant speed during rotation. A certain amount of corn seeds can be stored in the hopper 32. When necessary, a connecting frame is provided on one side thereof to cooperate with the feeder for fixing.

[0061] Specifically, Figure 7 As shown: the hot air generating component 53 includes a boosting bucket 531, the inner wall of the boosting bucket 531 is rotatably mounted with a fan blade 533, one end of the fan blade 533 is fixed to the output shaft of the driver 51, and the air inlet of the boosting bucket 531 is mounted with an electric heating wire 532.

[0062] By setting up the boosting bucket 531, the fan blades 533 arranged therein can form low-pressure areas and high-pressure areas in the boosting bucket 531 when rotating, thereby achieving the guided flow and pressurization of the airflow. The heating wire 532 emits heat to cool the airflow, so that the airflow is heated after passing through it. The temperature changes with the flow rate of the airflow, avoiding excessively high or low temperatures, thereby maintaining the best drying effect.

[0063] Specifically, Figure 1 As shown, the reduction wheel set 52 is two pulleys with different diameters, and is respectively fixed to the driving end of the driver 51 and the material leveling wheel 33, so as to ensure a constant speed difference between the material leveling wheel 33 and the fan blades 533.

[0064] By setting up a reduction wheel group 52, which is driven by a belt with two pulleys, one large and one small, and the pulley of the fan blade 533 is smaller, the fan blade 533 is kept at a faster rotation speed to meet the need of guiding the drying airflow, so that the fan blade 533 and the material leveling wheel 33 present a constant rotation speed difference, avoiding misoperation that causes the airflow and the falling material to be uncoordinated, resulting in insufficient drying, affecting the normal planting effect of corn seeds.

[0065] Specifically, Figure 6 and Figure 9 As shown, the discharging assembly 54 also includes a gas circuit tee 544 connected to the two slow flow covers 543, and one end of the gas circuit tee 544 is connected to the air outlet of the boosting bucket 531.

[0066] By setting the air circuit tee 544 to be connected with the boost bucket 531, the pressurized airflow can be evenly divided into the two slow flow covers 543 through the air circuit tee 544, and the space in the slow flow cover 543 gradually increases, so that the pressurized airflow is diffused, and the flow velocity is reduced to a certain extent, so as to avoid the excessive flow rate affecting the falling of the corn seeds. At the same time, the air flow velocity after the reduction is still fast, so as to maintain a fast-flowing hot airflow on the surface of the corn seeds, so as to achieve the effect of rapid drying. At the same time, the water material on the surface of the corn seeds is dried as it contacts with the hot airflow, and the time for the corn seeds to fall freely and vibrate is short, so that they will not be overheated, so that the surface is quickly dried and the overall coating efficiency is high.

[0067] Specifically, as Figure 10 shown: On both sides of the aggregate box 21, a left truss 23 and a right truss 24 are respectively fixed, and both the left truss 23 and the right truss 24 are fixed on the vertical frame 10, and the storage box 61 is fixedly penetrated on the right truss 24.

[0068] By setting the aggregate box 21, the aggregate box 21 is fixed to the intermittent cover 41 by screws, and there is always a gap between the intermittent hopper 22 fixedly penetrated therein and the intermittent cover 41. Corn seeds cannot pass through this gap, but the water and material on the inner wall of the intermittent cover 41 can flow through accordingly, achieving an effect of maintaining a spacing. At the same time, the aggregate box 21 can converge the water and material passing through this gap;

[0069] On both sides of the aggregate box 21, there are a left truss 23 and a right truss 24 respectively, enabling the aggregate box 21 to be stably installed based on the vertical frame 10, achieving a load-bearing and supporting effect for the middle part. At the same time, the right truss 24 can support the storage box 61 thereon.

[0070] When this solution is in use, the driver 51 drives the reduction gear set 52 to rotate, enabling the hot air generating component 53 and the material distributor 30 to operate simultaneously. At the same time, the pump body 72 is started. The pump body 72 pumps out the water and material in the liquid storage tank 71, pressurizes and transports it into the two shunt pipes 43. The water and material in the shunt pipes 43 enter a number of flat nozzles 42 under pressure and are sprayed in a fan shape and obliquely. The water and material obliquely pass through the falling corn seeds and then contact the inner wall of the intermittent cover 41 with an inner diameter in the shape of a horn and gradually widening from narrow to wide, enabling the excess water and material passing through and the corn to flow down along the inner wall of the intermittent cover 41. At the same time, a small amount of splashed water and material falls freely with the corn seeds under the action of gravity. Based on the action of the upward airflow, the small amount of splashed water and material forms an arc-shaped trajectory when falling and adheres to the inner wall of the intermittent cover 41 and converges downward;

[0071] The water and material converging in the aggregate box 21 enter the liquid storage tank 71 through the confluence pipe and are recycled under the action of the pump body 72 again.

[0072] The reduction gear set 52 drives the material distributing wheel 33 in the material distributing bin 31 to rotate. There are multiple protrusions on the surface of the material distributing wheel 33, which can quantitatively transport the corn raw materials in the hopper 32 during rotation, keeping the corn raw materials falling quantitatively and continuously;

[0073] When the driver 51 drives the fan blade 533 of the hot air generating component 53 to rotate, the heating wire 532 is started, enabling the outside air to pass through the heating wire 532 for heating. The heated air is pressurized under the action of the fan blade 533 and enters the two flow-equalizing covers 543 through the air path tee 544. The airflow entering the flow-equalizing covers 543 decelerates, and during the deceleration, it performs the last step of drying on the corn raw materials falling in the inclined guide groove 541, and continuously dries the falling corn seeds during the upward movement;

[0074] Among them, from Figure 9 it can be seen that a gate for controlling the opening degree is provided at the bottom end of the inclined guide groove 541. During use, the opening degree of the gate is adjusted according to the falling speed of the corn seeds, and it is ensured that the corn seeds can just fall, reducing the leakage amount of air flow from this place. At the same time, the inclined guide groove 541 is fixedly communicated with the pressurizing cover through the flow-attenuating cover 543 and the air path tee 544 at the bottom. When the vibration force generated by the high-speed rotation of the fan blade 533 is fed back to the inclined guide groove 541, the inclined guide groove 541 vibrates, and the coated corn seeds fall along the inclined plane during vibration (forming a material movement mechanism of a fluidized bed), so that the corn seeds move downward along with the hot air flow and vibration and slide out in sequence. During the sliding out process, since there is partial air flow flowing out at the bottom of the inclined guide groove 541, the corn seeds will fall in a parabola along with the air flow, which is convenient for receiving;

[0075] And this process combines the contact drying with the hot air flow during free fall, and further fully dries based on the moving principle of the fluidized bed formed at the bottom. Compared with the stirring method, through the moving coating method based on the free fall and the fluidized bed principle, the corn will not be excessively squeezed and rubbed against each other, resulting in coating peeling off (especially for corn seeds with smooth and irregular surfaces like corn, the probability of coating peeling off is greater). It enables the corn to have a uniform coating quality and has a very high coating efficiency for continuous coating operations.

[0076] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
