Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grain conveying, and particularly relates to a kind of automatic grain transport equipment. BACKGROUND

[0002] Generally, after the external harvesting of grain is completed, it needs to be placed in a granary for storage. When the grain needs to be transported, a grain conveyor is generally used to transport and transfer the grain inside the granary. In order to facilitate the packaging of the grain in the later stage, some existing grain conveyors can pretreat the dust or impurities on the surface of the transported grain.

[0003] A Chinese patent document with publication number CN115924569B discloses a grain conveyor and a method for using the same. The grain conveyor includes a pretreatment box, a conveying belt is arranged inside a material conveying groove formed in the bottom of the pretreatment box, a rotating rod is symmetrically connected to the upper part of the inner wall of the pretreatment box, a material conveying impeller is connected to the middle part of the rotating rod, a collecting box is fixedly connected to the right side of the outer wall of the pretreatment box, and a cleaning mechanism that cooperates with the collecting box is movably connected to the middle part of the inner wall of the pretreatment box. In the present application, the cooperation of the distribution plate, the hook claw, and the discharging strip and other components improves the impurity removal effect. The cooperation of the distribution plate, the nylon wire, and the air suction fan blade and other components avoids the reduction of the impurity removal effect caused by the concentration of a large amount of grain for dust removal. In addition, the mechanical transmission mode is used for dust extraction, which avoids the use of electronic equipment such as a motor to increase the use and maintenance cost.

[0004] In the above patent document, the hook claw is used to clean the straw. However, when the straw is too long or the grain is too much, the grain and straw cannot completely enter the cleaning bin, which easily causes the straw to not be clamped by the hook claw, and some of the straw is parallel to the direction of the hook claw, which causes the hook claw to not be able to hook the straw. Therefore, the cleaning effect of the straw in the above patent document needs to be improved. SUMMARY

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1-6 As shown, an automated grain transport equipment includes a conveyor belt 1, a support frame 2, and a screening structure 3.

[0029] The conveyor belt 1 is used to transport grain. The support frame 2 is set on both sides of the conveyor belt 1. When the conveyor belt 1 transports grain, it prevents the grain from falling through the gap between the conveyor belt 1 and the support frame 2. The drive roller on the conveyor belt 1 is rotatably mounted on the support frame 2. A rotating motor (not shown in the figure) is set on the drive roller to make the drive roller rotate.

[0030] The screening structure 3 includes a rotating sleeve 31 and receiving plates 32 that are evenly distributed around the circumference of the rotating sleeve 31 and in contact with the support frames 2 on both sides. The rotating sleeve 31 is rotatably mounted on the support frame 2. The receiving plate 32 is arc-shaped and has an installation groove along its length. Arc-shaped plates 33 are evenly distributed from left to right on the installation groove. The support frame 2 is also fixedly mounted with a receiving groove 4 that can fit against the inner end of the receiving plate 32 and has an open top.

[0031] When the rotating sleeve 31 rotates, the receiving plate 32 rotates with the rotating sleeve 31, and when the outer end of the receiving plate 32 contacts the conveying belt 1, the grain on the conveying belt 1 passes through the receiving plate 32 during conveying. Since the receiving plate 32 is provided with the arc-shaped plates 33, the grain is filtered by the arc-shaped plates 33, and the grain passing through the arc-shaped plates 33 continues to move with the conveying belt 1. The ray L emitted from any point A on one of the two adjacent arc-shaped plates 33 intersects with points B on the two arc-shaped plates 33. Taking the straw as the ray L, when the straw passes between the two arc-shaped plates 33, the straw is blocked by the arc-shaped plates 33 and cannot pass between the arc-shaped plates 33. When the receiving plate 32 intercepts more straws, the efficiency of the grain passing through the receiving plate 32 decreases. At this time, the rotating sleeve 31 rotates and rotates another receiving plate 32 to the position contacting the conveying belt 1, and continues to filter the grain on the conveying belt 1.

[0032] The support frame 2 is fixedly provided with a receiving groove 4 which can be attached to the inner end of the receiving plate 32 and has an open top. One end of the receiving groove 4 penetrates the support frame 2 and extends to the outside of the support frame 2, and the other end of the receiving groove 4 extends to contact the rotating sleeve 31. The support frame 2 is provided with a driving motor 70, and the driving motor 70 is fixedly provided with an auger blade 71 located in the receiving groove 4. The driving motor 70 is fixedly connected between the driving motor 70 and the rotating sleeve 31.

[0033] When one receiving plate 32 contacts the conveying belt 1 for a period of time, the rotating sleeve 31 is driven to rotate by the driving motor 70, thereby driving the receiving plate 32 to rotate. During the upward rotation of the receiving plate 32, the blocked straws between the arc-shaped plates 33 will fall off between the arc-shaped plates 33 and move towards the inner end of the receiving plate 32. In this process, the receiving plate 32 is always attached to the receiving groove 4 to avoid the straws from falling onto the grain again. When the receiving plate 32 rotates by a certain angle, the inner end of the receiving plate 32 is located above the opening of the receiving groove 4 and the blocked straws on the receiving plate 32 are poured into the receiving groove 4. When the receiving plate 32 rotates, the auger blade 71 follows the rotation and pushes the straws in the receiving groove 4 out of the receiving groove 4, avoiding subsequent manual cleaning.

[0034] One side of the support frame 2 is provided with an inclined downward guide groove 80, and the guide groove 80 is arranged below the receiving groove 4. When the straws are guided out of the receiving groove 4, they fall into the guide groove 80. In specific embodiments, a collection box, a collection bag or the like can be arranged at the discharge end of the guide groove 80 to collect the straws.

[0035] In the preferred embodiment of the present application, connecting rods 60 are arranged between the arc-shaped plates 33 along the left-right direction; during actual operation of the device, there may be some straws that are parallel to the length direction of the arc-shaped plates 33, and the straws may move along with the conveying belt 1 after passing through the arc-shaped plates 33; the connecting rods 60 are arranged between the arc-shaped plates 33 to achieve better filtering effect on the grains, and meanwhile, the efficiency of the grains passing through the screening structure 3 is ensured.

[0036] The knocking assembly comprises a knocking rod 50, a first elastic member 51 and a protrusion 52; the knocking rod 50 is slidingly arranged on the receiving plate 32 and fixedly connected with all the arc-shaped plates 33 in the same row; the first elastic member 51 is arranged between the knocking rod 50 and the receiving plate 32; the protrusions 52 are evenly distributed along the circumference of the rotating sleeve 31 on the support frame 2 and compress the first elastic member 51; the knocking rod 50 is separated from the protrusions 52 and hits the support frame 2; the end of the knocking rod 50 is circular; the end of the protrusion 52 in contact with the knocking rod 50 is provided with a circular chamfer; the knocking rod 50 is fixedly connected with the arc-shaped plates 33; the first elastic member 51 is a compression spring; one end of the compression spring is connected with the receiving plate 32, and the other end is connected with the knocking rod 50.

[0037] In other embodiments of the present application, the compression spring can be replaced by an elastic sheet; one end of the elastic sheet is connected with the receiving plate 32, and the other end is connected with the knocking rod 50.

[0038] The receiving plate 32 is separated from the conveying belt 1 and rotates upward; the knocking rod 50 rotates along with the receiving plate 32; the end of the knocking rod 50 is circular, so that the knocking rod 50 does not interfere with the protrusions 52 during rotation and contact with the protrusions 52; when the knocking rod 50 contacts the protrusions 52, the spring is compressed; after the knocking rod 50 is separated from the protrusions 52, the spring is stretched and the end of the knocking rod 50 hits the support frame 2, so that the knocking rod 50 vibrates; since the knocking rod 50 is fixedly connected with the arc-shaped plates 33, the arc-shaped plates 33 also vibrate; the grains between the arc-shaped plates 33 fall off the arc-shaped plates 33; when the receiving plate 32 rotates to above the receiving groove 4, the vibration of the arc-shaped plates 33 can help the straws to fall into the receiving groove 4

[0039] The outer end of the receiving plate 32 is rotationally provided with a rotating shaft 41, a hook 42 is arranged along the length direction of the rotating shaft 41, a spiral groove 43 is formed at one end of the rotating shaft 41, a fixed block 44 is fixedly arranged on the receiving plate 32, the fixed block 44 is relatively slid with the spiral groove 43, the second elastic member 45 is arranged between the rotating shaft 41 and the receiving plate 32, the supporting frame 2 is provided with a pressing table 46 which enables the rotating shaft 41 to slide in the left-right direction, a slope is connected between the pressing table 46 and the supporting frame 2, when the rotating shaft 41 is separated from the pressing table 46, the second elastic member 45 is elongated and reversely slides and rotates the rotating shaft 41, and then the hook 42 collides with the receiving plate 32, the second elastic member 45 is a spring, one end of the spring abuts against the receiving plate 32, and the other end abuts against the rotating shaft 41.

[0040] During the conveying of the grain, the grain passes through the screening structure 3, and after the screening structure 3 works for a period of time, more straws are gathered at the end of the receiving plate 32 close to the conveying belt 1, when the next receiving plate 32 rotates to the position in contact with the conveying belt 1, the straws will enter the receiving plate 32 when moving with the conveying belt 1, so that the receiving plate 32 is blocked, and the filtering effect of the grain is reduced, by arranging the hook 42, when the receiving plate 32 rotates to contact with the conveying belt 1, the rotating shaft 41 contacts with the pressing table 46, the rotating shaft 41 compresses the second elastic member 45, the spiral groove 43 on the rotating shaft 41 contacts with the fixed block 44 on the receiving plate 32, the rotating shaft 41 rotates and rotates the hook 42, the hook 42 is expanded and adheres to the conveying belt 1, when the receiving plate 32 rotates, the hook 42 lifts most of the straws at the end of the receiving plate 32, the straws rotate with the receiving plate 32 and finally fall into the receiving groove 4, when the next receiving plate 32 contacts with the conveying belt 1, the straws will not block the receiving plate 32, when the receiving plate 32 rotates and separates the rotating shaft 41 from the pressing table 46, the second elastic member 45 is elongated and moves the rotating shaft 41 on the receiving plate 32, the spiral groove 43 and the fixed block 44 relatively rotate, and then the rotating shaft 41 rotates, the rotating shaft 41 drives the hook 42 to retract and collide with the receiving plate 32, so that the receiving plate 32 vibrates to assist the grain between the arc-shaped plates 33 to fall.

[0041] The projection of the hook 42 in the front-rear direction is in the shape of an inverted triangle, the receiving plate 32 is provided with a receiving hole 47 for accommodating the hook 42, and the receiving hole 47 penetrates the receiving plate 32; the hook 42 is arranged in the shape of an inverted triangle, so as to avoid crushing the grain on the conveying belt 1 after the hook 42 is expanded, by arranging the receiving hole 47, the receiving hole 47 can also filter the grain when the conveying belt 1 conveys the grain, but there will be a situation that part of the straws pass through the receiving hole 47.

[0042] In other embodiments of the present application, the accommodating holes 47 are not through the material receiving plates 32, so that the straw can not pass through the accommodating holes 47, and the claws 42 can crush the grain in the accommodating holes 47 when the claws 42 are retracted into the accommodating holes 47.

[0043] The specific working principle of the present application is as follows:

[0044] When the grain is moved along the conveying belt 1, the grain is filtered by the screening structure 3, and the straw is blocked by the arc-shaped plates 33. After one of the material receiving plates 32 is in contact with the conveying belt 1 for a period of time, the number of the straw between the arc-shaped plates 33 is increased, the driving motor 70 is rotated to drive the material receiving plate 32 to rotate so that the straw on the material receiving plate 32 falls into the material receiving groove 4. When the knocking rod 50 is rotated and in contact with the protrusion 52 to compress the first elastic member 51, the knocking rod 50 is separated from the protrusion 52, and the knocking rod 50 hits the support frame 2 and causes the arc-shaped plates 33 to vibrate, so that the grain between the arc-shaped plates 33 falls, and the vibration can assist the straw to fall into the material receiving groove 4. When the material receiving plate 32 is rotated, the straw is lifted by the claws 42, so that the straw does not block the material receiving plate 32 when the next material receiving plate 32 is in contact with the conveying belt 1, and the screening efficiency of the grain is improved.

[0045] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
