Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of grain storage equipment, specifically a multi-stage chute feeder. Background Technology
[0002] When feeding grain through a feeder, theoretically, the more discharge ports of the feeder, the more material piles are formed in the silo, the smaller the height difference of the material piles, the better the automatic grading effect of breaking down impurities in the grain, the more uniform the distribution of impurities in the grain, the less workload of leveling the silo, and the higher the safety of leveling the silo. As a result, more and more feeders are starting to use multi-stage chutes to increase the number of chute discharge ports.
[0003] For example, the Chinese utility model patent with authorization announcement number CN220925674U discloses a gravity self-scattering grain-saving, loss-reducing and anti-grading silo grain distributor. Its description states that "the chute group 5 is a 'Y' shaped chute structure. The chute group 5 includes several fish-scale chute 51 and a branch chute 52. The branch chute 52 is 'Y' shaped. Several fish-scale chute 51 arranged in a 'I' shape are flanged to one inlet and two outlets of the branch chute 52 respectively."
[0004] In existing multi-stage sluices, the bottom plates of multiple sluices are all on the same plane. During sluice installation, the entire sluice needs to be tilted downwards to ensure that the material can slide under gravity. When the multi-stage sluice is tilted downwards, the rotation axis of the multi-stage sluice is generally parallel to the width direction of the main sluice. However, since there is an angle between the length direction of the branch sluice and the length direction of the main sluice, the width direction of the branch sluice will be tilted to the horizontal plane when the sluice is tilted downwards. When the material moves from the main sluice to the branch sluice, the material will gather on the inner side of the branch sluice under gravity, resulting in a difference in the thickness of the material in the branch sluice. When the branch sluice is reinstalled at the discharge end of the branch sluice, the material will be unevenly distributed from the first-level branch sluice to the second-level branch sluice. Furthermore, as in the sluice group disclosed in the above utility model patent, the discharge amount on both sides of the width direction of the branch sluice will be different when the material slides in the branch sluice, resulting in a greater height difference in the final material pile.
[0005] Based on this, the present invention designs a multi-stage chute material distributor to solve the above problems. Utility Model Content

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.
[0031] Please see Figure 1-7 This utility model provides a technical solution: a multi-stage chute feeder, including an installation cylinder 1, a first main chute 2, a first branch chute 3, and a second branch chute 4; multiple first main chute 2s are provided, and the multiple first main chute 2s are arranged circumferentially on the installation cylinder 1; the discharge end of the first main chute 2 is connected to at least two first branch chute 3s, and the discharge end of the first branch chute 3 is connected to at least two second branch chute 4s; the discharge ends of the first main chute 2, the first branch chute 3, and the second branch chute 4 are all inclined downwards; the first branch chute 3 includes a first base plate 31 and first side plates 32 provided on both sides of the width direction of the first base plate 31, and the width direction of the first base plate 31 is parallel to the horizontal plane;
[0032] The end of the first main chute 2 connected to the mounting cylinder 1 is the feed end. During operation, the material moves from the feed end of the first main chute 2 onto the first main chute 2. Since the discharge ends of the first main chute 2, the first branch chute 3, and the second branch chute 4 are all inclined downwards, when the material moves onto the first main chute 2, it will move towards the discharge end of the first main chute 2 under the action of gravity, and then move from the discharge end of the first main chute 2 onto the first branch chute 3. When the material moves onto the first branch chute 3, it will also move towards the discharge end of the first branch chute 3 under the action of gravity, and then move from the discharge end of the first branch chute 3 onto the first branch chute 3. When the material moves from the first branch chute 3 to the second branch chute 4, it will move towards the discharge end of the second branch chute 4 under the action of gravity, and finally be discharged from the discharge end of the second branch chute 4 and fall into the silo. By connecting at least two first branch chute 3s to the discharge end of the first main chute 2 and at least two second branch chute 4s to the discharge end of the first branch chute 3, the material can be distributed through more discharge ends during the distribution process. The number of material piles formed in the silo is greater and the height difference of the material piles is smaller, so that the material distribution is more uniform, the workload of silo leveling is reduced and the safety of silo leveling is improved.
[0033] The first branch chute 3 includes a first base plate 31 and a first side plate 32. The first base plate 31 has a first side plate 32 on both sides in the width direction. When the material moves on the first branch chute 3, the first base plate 31 is used to support the material, and the first side plate 32 is used to restrict the material and prevent the material from falling off the first base plate 31. In order to ensure the uniformity of the material when moving on the first base plate 31, the width direction of the first base plate 31 is parallel to the horizontal plane. Thus, when the material moves on the first base plate 31, it will be evenly distributed in the width direction of the first base plate 31. When the material moves from the discharge end of the first branch chute 3 to the second branch chute 4, the material will be evenly divided into multiple streams and moved into multiple second branch chute 4, thereby ensuring that the material thickness on each second branch chute 4 is consistent, ensuring the final uniform distribution of the material, and avoiding inconsistent material thickness on different branch chute 4.
[0034] like Figure 2 As shown, in this example, the discharge end of the first main chute 2 is connected to two first branch chute 3s, and the discharge end of the first branch chute 3 is connected to two second branch chute 4s. In this way, a single first main chute 2 can be divided into four second branch chute 4s, and a single first main chute 2 can correspond to four material distribution points.
[0035] Specifically, the end of the first base plate 31 closest to the first main chute 2 extends along the length of the first main chute 2 toward the feed end of the first main chute 2;
[0036] like Figure 4As shown, the discharge end of the first main chute 2 is connected to two first branch chute 3s. The first bottom plates 31 of the two first branch chute 3s extend towards the feed end of the first main chute 2. The part of the two first bottom plates 31 extending towards the feed end of the first main chute 2 forms the bottom end of the first main chute 2, eliminating the need for the part of the bottom end of the first main chute 2 to be bent or folded towards the first bottom plate 31, which makes production, processing and assembly simpler.
[0037] Specifically, the feed end of the first main chute 2 is provided with a transition section 21 for connecting the feed end of the first main chute 2 and the first base plate 31. The base plate of the transition section 21 is composed of two planes that intersect in the middle. These two planes become a straight line and are parallel to the horizontal plane on the side of the first main chute 2 near the mounting cylinder 1, and intersect with two first base plates 31 at the other end. The four plates share a common vertex.
[0038] like Figure 4 As shown, when the portion of the first base plate 31 extending towards the feed end of the first main chute 2 forms the bottom end of the first main chute 2, the bottom end of the first main chute 2 will form a structure with an arch in the middle. This will cause the material to be blocked when entering the first main chute 2 from the feed end. Furthermore, because the feed end of the first main chute 2 has an irregular shape, when assembling it with other components, other components need to be adapted to fit the shape of the feed end of the first main chute 2. Figure 5 As shown, in this example, the discharge end of the first main chute 2 is connected to two first branch chute 3s. The feed end of the first main chute 2 is provided with a transition section 21. The bottom plate of the transition section 21 is composed of two planes that intersect in the middle. These two planes become a straight line and are parallel to the horizontal plane on the side of the first main chute 2 near the mounting cylinder 1. At the other end, they intersect with two first bottom plates 31. The four plates share a common vertex. The transition section 21 is used to transition from the feed end of the first main chute 2 to the first bottom plate 31. In this way, when the material enters the first main chute 2, it will not be blocked. The material enters the first main chute 2 more smoothly. At the same time, when assembling the feed end of the first main chute 2 with other accessories, since the shape of the feed end of the first main chute 2 is more regular, there is no need to make adaptive shape changes to other accessories, making the assembly simpler.
[0039] Furthermore, the second branch chute 4 includes a second base plate 41 and second side plates 42 disposed on both sides of the second base plate 41 in the width direction, wherein the width direction of the second base plate 41 is parallel to the horizontal plane.
[0040] like Figure 6-7As shown, the second branch chute 4 includes a second base plate 41 and a second side plate 42. The second base plate 41 is provided with the second side plate 42 on both sides in the width direction. The second base plate 41 is used to support the material for material movement, and the second side plate 42 is used to restrict the material on the second base plate 41 and prevent the material on the second base plate 41 from falling off the second base plate 41. After the width direction of the first base plate 31 is parallel to the horizontal plane, it can be ensured that the material has a uniform thickness when moving on the first base plate 31. After being divided into two by the transition section 21, it enters the second branch chute. The width direction of the second base plate 41 is parallel to the horizontal plane, so that the material has a uniform thickness when moving on the second base plate 41, and the material is prevented from concentrating on one side of the width direction of the second base plate 41 and overflowing onto the second side plate 42, thus preventing the material from leaking from the side of the second branch chute 4.
[0041] Furthermore, the multi-stage chute distributor also includes a plurality of second main chutes 5 arranged circumferentially on the outer periphery of the mounting cylinder 1. The discharge end of the second main chutes 5 is connected to at least two third branch chutes 6. The discharge ends of the second main chutes 5 and the discharge ends of the third branch chutes 6 are both inclined downwards, and the distance from the discharge end of the third branch chutes 6 to the mounting cylinder 1 is not greater than the distance from the discharge end of the first branch chutes 3 to the mounting cylinder 1.
[0042] When spreading material, the more spreading points there are, the more material piles will be formed in the bin after spreading, the smaller the height difference of the material piles, and the more uniform the material distribution. By installing a second main chute 5 on the installation cylinder 1, and connecting at least two third branch chute 6 to the discharge end of the second main chute 5, material is conveyed into the second main chute 5 and discharged from the discharge end of the third branch chute 6, thereby increasing the number of spreading points during spreading. The distance from the discharge end of the third branch chute 6 to the installation cylinder 1 is not greater than the distance from the discharge end of the first branch chute 3 to the installation cylinder 1, so that the material pile corresponding to the third branch chute 6 and the material pile corresponding to the second branch chute 4 are misaligned in the radial direction of the bin, making the material distribution more uniform during spreading.
[0043] like Figure 2 As shown, after the material enters the second main chute 5, it moves towards the discharge end of the second main chute 5 under the action of gravity, and then moves from the discharge end of the second main chute 5 to the third branch chute 6. Subsequently, the material moves towards the discharge end of the third branch chute 6 on the third branch chute 6, and finally is discharged from the discharge end of the third branch chute 6 into the silo.
[0044] like Figure 2 As shown, the second main chute 5 is stacked vertically relative to the first main chute 2;
[0045] Furthermore, the third branch chute 6 includes a third base plate 61 and third side plates 62 disposed on both sides of the width direction of the third base plate 61. The width direction of the third base plate 61 is parallel to the horizontal plane, and a central discharge port 63 is provided at the middle position of the length direction of the third base plate 61.
[0046] like Figure 3 As shown, the third branch chute 6 includes a third base plate 61 and a third side plate 62. The third base plate 61 is used to support materials for material movement. The third side plates 62 are provided on both sides of the third base plate 61 in the width direction to prevent materials from leaving the third base plate 61 in the width direction. During operation, the material discharged from the discharge end of the second main chute 5 will move from the feed end of the third branch chute 6 to the third base plate 61 and move towards the discharge end of the third base plate 61 under the action of gravity. During the process of the material moving towards the discharge end of the third base plate 61, the material will pass through the middle discharge port 63 opened on the third base plate 61. At this time, some material will be discharged from the third branch chute 6 through the middle discharge port 63 and scattered into the silo. By opening the middle discharge port 63 on the third base plate 61, the number of material distribution points can be increased, the height difference of the material pile after material distribution can be further reduced, and the material distribution can be more uniform.
[0047] The width direction of the third base plate 61 is parallel to the horizontal plane. When the material moves on the third base plate 61, the material thickness in the width direction of the third base plate 61 is consistent. By controlling the opening length of the middle discharge port 63 in the width direction of the third base plate 61, the amount of material discharged from the middle discharge port 63 can be precisely controlled.
[0048] Furthermore, a baffle plate 64 that curves upward is provided on the side of the central discharge port 63 near the discharge end of the third branch chute 6;
[0049] Since the discharge end of the third branch chute 6 is inclined downward, the material on the third bottom plate 61 will move downward under the action of gravity. In order to prevent the material from directly passing the middle discharge port 63, a baffle plate 64 is set on the side of the middle discharge port 63 near the discharge end of the third branch chute 6. The baffle plate 64 can prevent the material from directly passing the middle discharge port 63, thereby ensuring the amount of material discharged from the middle discharge port 63.
[0050] Furthermore, the mounting cylinder 1 is provided with a reinforced connection structure for connecting the first branch chute 3 and the third branch chute 6;
[0051] Specifically, the reinforced connection structure includes a lower support rod 71 and an upper pull rope 72. The two ends of the lower support rod 71 are respectively connected to the mounting cylinder 1 and the lower end face of the third branch chute 6, and the two ends of the upper pull rope 72 are respectively connected to the mounting cylinder 1 and the upper end face of the first branch chute 3.
[0052] like Figure 1As shown, the reinforcing structure includes a lower support rod 71 and an upper pull rope 72. The lower support rod 71 is mounted on the mounting cylinder 1 and is connected to the lower end face of the third branch chute 6 through one end away from the mounting cylinder 1, for supporting the third branch chute 6 from below. The upper pull rope 72 is also mounted on the mounting cylinder 1, and the upper pull rope 72 is connected to the upper end face of the first branch chute 3 through one end away from the mounting cylinder 1, for pulling the first branch chute 3 from above, thereby increasing the installation stability of the first main chute 2, the second main chute 5, the first branch chute 3, the second branch chute 4, and the third branch chute 6.
[0053] like Figure 2 As shown, in this example, the second main chute 5 is located directly below the first main chute 2, and the third branch chute 6 is located directly below the first branch chute 3 and is fixedly connected to the first branch chute 3. Thus, the lower support rod 71 and the upper pull rope 72 can also increase the installation stability of the second main chute 5 and the third branch chute 6.
[0054] Furthermore, a connecting rod 81 or a transverse pull rope 82 is connected between adjacent first branch chutes 3, and the connecting rod 81 and the transverse pull rope 82 are used alternately between adjacent first branch chutes 3;
[0055] As shown in the figure, a connecting rod 81 or a horizontal pull rope 82 is provided between adjacent first branch chutes 3. The connecting rod 81 is made of rigid material, and the connecting rod 81 and the horizontal pull rope 82 are used alternately to horizontally limit the first branch chutes 3, so as to ensure the accuracy of the first main chutes 2, the first branch chutes 3 and the second branch chutes 4 in the horizontal direction.
[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
