Description

Technical Field

[0001] The invention relates to the technical field of conveyors, in particular to a belt conveyor with a material dividing function. Background Art

[0002] Agricultural products refer to primary products produced by agriculture, that is, products that are directly produced by farmers in the fields and have not been processed or have only been preliminarily processed. These products mainly include food crops (such as wheat and rice), cash crops (such as cotton and rapeseed), vegetables and fruits, meat, eggs, milk and aquatic products. Among them, agricultural product belt conveyor is a kind of equipment widely used in the production, processing and transportation of agricultural products.

[0003] After the peppers are harvested, they are usually put on a belt conveyor. The process first involves flattening the peppers so that they are evenly distributed on the conveyor belt to ensure smooth subsequent processing. Then, impurities are removed during the conveying process. The peppers are then transported to the manual sorting area for sorting. In actual use, the harvested peppers are mixed with pepper leaves, which are usually soft and have a certain degree of toughness. When the peppers pass through the flattening component on the conveyor, the pepper leaves may connect two or more peppers like ropes. Due to the limited opening between the flattening component and the conveyor belt, this combination of peppers entangled by pepper leaves may not be smooth due to the increase in overall size. They may be stuck in the gap between the flattening component and the conveyor belt, causing the conveyor to be obstructed or even malfunction. This situation will not only affect the normal transportation and sorting efficiency of the peppers, but may also cause damage to the equipment. For this reason, we propose a belt conveyor with a material sorting function. Summary of the invention

A plurality of roller plates are installed equidistantly outside the second connecting shaft and inside the feeding hopper, and the outer walls of the roller plates are provided with nylon bristles.

[0012] In some embodiments, the pepper stirring assembly includes a connecting rod member fixed to the outer end of the second connecting shaft, a third connecting shaft is fixed to the end of the connecting rod member away from the second connecting shaft, and a plurality of upper levers are equidistantly installed on the outside of the third connecting shaft, and the upper levers extend to the interior of the feeding hopper.

[0013] In some embodiments, the upper lever is located below the rolling plate, and the upper lever and the rolling plate are alternately distributed.

[0014] In some embodiments, the opening and closing assembly includes a connecting rod connected to the end of the movable baffle, and a vertical rotating rod is connected to the connecting rod. The rotating rod passes through the frame of the conveyor body through a bearing.

[0018] The present invention has at least the following beneficial effects:

[0019] 1. Improve the paving effect: The pepper leaf removal component and the pepper stirring component cooperate so that before the peppers are spread out, the nylon bristles on the rolling plate can contact the pepper leaves and stick to them. At the same time, the inner end of the upper lever on the third connecting shaft rotates and lifts up periodically. The peppers and pepper leaves will be dispersed in this process, which can effectively improve the working efficiency of the pepper leaf removal component, thereby improving the quality and efficiency of the entire paving and subsequent material sorting work. By removing most of the pepper leaves, a certain distance can be maintained between the peppers. During the transportation process, the peppers will not be piled up due to crowding, but can be arranged in an orderly manner, and can avoid being stuck in the gap between the paving component and the conveyor belt, thereby ensuring smooth transportation.

[0020] 2. Reduce costs: The paving component, pepper leaf removal component and pepper stirring component share a drive motor through a suitable transmission mechanism, which effectively reduces the overall cost investment and avoids the space waste and energy consumption caused by multiple motors. Through reasonable structural design, the drive motor can provide power for each component to ensure the coordinated work between the components.

[0021] 3. Improve the efficiency of conveying: In order to solve the problem of congestion or inability to pass due to the large size of peppers, the second motor is started to drive the second gear to rotate, so that the racks on both sides move in opposite directions, thereby driving the movable baffle to open or close synchronously, which can effectively avoid blockage and reduce the residence time of large peppers in the conveying process. It not only improves the conveying efficiency, but also avoids the blockage problem caused by the large size of peppers. It has high practical value in the actual process of conveying and dividing peppers. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-Figure 11 As shown, the present invention provides a technical solution: a belt conveyor with a material dividing function, including a conveyor body 1, the conveyor body 1 is composed of a first conveying part 101, a blower part 103 and a second conveying part 102 arranged along the conveying sequence, the blower part 103 is installed between the first conveying part 101 and the second conveying part 102, the first conveying part 101 is arranged obliquely upward, the feeding end of the second conveying part 102 is below the dropping end of the first conveying part 101, the blower part 103 is used to blow away impurities, dust and the like in peppers, and a feeding hopper 2 is provided at the feeding end of the first conveying part 101. The above is the prior art and will not be repeated here. It also includes a flattening component 3, a pepper leaf removal component 4, a pepper stirring component 5, an opening and closing component 6 and a movable baffle 7. The flattening component 3 is arranged in the feeding hopper 2, and the flattening component 3 is used to spread the peppers added to the feeding hopper 2 on the conveyor belt, and the flattening component 3 includes a plurality of rotatable material diverting plates 33, and the plurality of material diverting plates 33 are divided into The side end of the material-dividing plate 33 is provided with a large pepper passage opening 34. When the bottom end of the material-dividing plate 33 is perpendicular to the upper end surface of the conveyor belt at the first conveying part 101, a certain gap is left between the bottom end of the material-dividing plate 33 and the upper end surface of the conveyor belt to accommodate the passage of normal peppers (based on the specifications of most similar peppers); the pepper leaf removing component 4 is rotatably arranged in the feeding hopper 2, and the pepper leaf removing component 4 is used to adhere to the pepper leaves mixed in the peppers fed into the feeding hopper 2 to avoid the peppers The leaves wrap two or more peppers to be laid flat; the pepper stirring component 5 is arranged below the pepper leaf removing component 4, and the pepper stirring component 5 can be periodically moved up with the rotation of the pepper leaf removing component 4 to scatter the pepper leaves mixed in the peppers, so that the pepper leaves can be removed by using the pepper leaf removing component 4, and the movable baffle 7 is arranged on one side of the bottom end of the feeding hopper 2, and the movable baffle 7 is adapted to the large pepper passage port 34, and the opening and closing component 6 is used to realize the opening or closing of the large pepper passage port 34.

[0041] Among them, see Figure 5 and Figure 7As shown, the flattening component 3 includes a first motor 31 installed on the outer wall of the feeding hopper 2. The first motor 31 can be a servo motor. The output end of the first motor 31 is connected to the first connecting shaft 32 in the feeding hopper 2. A plurality of material shifting plates 33 are fixed to the outside of the first connecting shaft 32 in a ring array. By starting the first motor 31, the output end of the first motor 31 can be used to drive the first connecting shaft 32 to rotate, and then the material shifting plates 33 outside the first connecting shaft 32 can be used to periodically flatten the peppers sent to the first conveying part 101, so as to facilitate subsequent impurity removal and manual material sorting.

[0042] A large chili pepper guide plate 35 is connected to the bottom end of the outer wall of the material-diverting plate 33. The outer wall of the large chili pepper guide plate 35 is a material-guiding slope. The material-guiding slope shows a trend of gradually decreasing from the middle of the material-diverting plate 33 to the large chili pepper passage 34. The chili peppers added to the hopper 2 will more or less contain some larger chili peppers. The specifications of such chili peppers are larger than those of normal chili peppers, so that they cannot be spread on the first conveying part 101 through the flattening component 3. At this time, the large chili pepper guide plate 35 with a material-guiding slope is used to guide the large chili peppers to both sides.

[0043] See also Figure 5 and Figure 6 As shown, the pepper leaf removal component 4 includes a second connecting shaft 42 that passes through the feeding hopper 2, and transmission wheels 44 are installed at the outer ends of the first connecting shaft 32 and the second connecting shaft 42, and a transmission belt 41 is connected between the two transmission wheels 44. A plurality of rolling plates 43 are installed equidistantly outside the second connecting shaft 42 and inside the feeding hopper 2, and the outer wall of the rolling plate 43 is provided with nylon bristles 45. The nylon bristles 45 are soft and have a certain elasticity. This material can effectively hang the pepper leaves without damaging the surface of the pepper. The length of the bristles is preferably 8-12 cm. A layer of bristles is formed on the surface, and the top of the bristles can be designed to be flat to increase the contact area with the pepper leaves and facilitate the hooking of the leaves. At the same time, the shape of the bristles can be optimized according to the circular motion of the rolling plate 43 so that it can better grasp the leaves when the rolling plate 43 rotates, such as an oblique bending design: the principle is to make the bristles bend obliquely along the direction of motion. For example, when the rolling plate 43 rotates clockwise, the bristles are tilted and bent to the right, so that during the rotation of the rolling plate 43, the bristles can more effectively cut into the gap between the leaves and the pepper when they come into contact with the leaves, thereby increasing the friction for grasping the leaves.

[0044] See also Figure 5 and Figure 6As shown, the pepper stirring assembly 5 includes a connecting rod member 51 fixed to the outer end of the second connecting shaft 42, the connecting rod member 51 is hinged by three connecting strips, a third connecting shaft 52 is fixed to one end of the connecting rod member 51 away from the second connecting shaft 42, and a plurality of upper shifting rods 53 are equidistantly installed on the outside of the third connecting shaft 52, and the upper shifting rods 53 extend to the inside of the feeding hopper 2, wherein the upper shifting rods 53 are located below the rolling plate 43, and the upper shifting rods 53 and the rolling plate 43 are distributed alternately.

[0045] Through the above, when it is used specifically, the belt conveyor is started first, and then the peppers to be sorted are poured into the inside of the feeding hopper 2. Through the action of the flattening component 3, the peppers can be flattened on the first conveying part 101 for conveying. The peppers are conveyed into the blower part 103 through the first conveying part 101 and then fall down. The lighter impurities are blown away by the blower, and the heavier peppers are conveyed to the second conveying part 102. The staff can be on both sides of the second conveying part 102 for sorting.

[0046] After the peppers to be sorted are poured into the hopper 2, the rotation of the first connecting shaft 32 can drive the transmission wheel 44 to rotate, and the rotation of the transmission wheel 44 will drive the transmission belt 41 to move, and the transmission belt 41 will then drive the second connecting shaft 42 to rotate synchronously. As the second connecting shaft 42 rotates, the rolling plate 43 also starts to rotate. The nylon bristles 45 on the rolling plate 43 come into contact with the pepper leaves during the rotation of the rolling plate 43 and stick to the pepper leaves.

[0047] At the same time, the rotation of the second connecting shaft 42 will also synchronously drive the connecting rod 51 to operate. The movement of the connecting rod 51 causes the inner end of the upper lever 53 on the third connecting shaft 52 to rotate and lift periodically. When the added peppers are lifted up by the upper lever 53, the peppers and pepper leaves will be dispersed in the process. This will facilitate the use of the pepper leaf removal component 4 to perform certain processing on the mixed pepper leaves.

[0048] Among them, during the rotation of the rolling plate 43, the nylon bristles 45 will contact the pepper leaves as the rolling plate 43 rotates. Due to the stickiness of the bristles, the leaves will be adhered to the bristles, and when the peppers are lifted by the upper lever 53, the peppers and the pepper leaves can be better separated. This design can effectively improve the working efficiency of the pepper leaf removal component 4, ensuring that the peppers and pepper leaves are more fully processed, thereby improving the quality and efficiency of the entire paving and subsequent material sorting work, and by removing most of the pepper leaves, it can greatly avoid the pepper leaves wrapping two or more peppers together, so that the peppers can be dispersed. The paving component 3 can evenly spread the peppers on the conveyor belt, so that a certain distance is maintained between the peppers. During the transportation process, the peppers will not pile up due to crowding, but can be arranged in an orderly manner to avoid being stuck in the gap between the paving component 3 and the conveyor belt, which can effectively avoid the occurrence of this situation and ensure smooth transportation.

[0049] See also Figure 8-Figure 11 As shown, the opening and closing assembly 6 includes a connecting rod 62 connected to the end of the movable baffle 7. A groove is provided at the position of the connecting rod 62 corresponding to the feeding hopper 2 to accommodate the movement of the connecting rod 62. A vertical rotating rod 63 is connected to the connecting rod 62, and the rotating rod 63 passes through the frame of the conveyor body 1 through a bearing.

[0050] The opening and closing assembly 6 also includes two fixed bars 64 fixed to the bottom end of the conveyor body 1 and a first gear 65 connected to the lower end of the rotating rod 63. A rack 66 is installed on the side of the fixed bar 64 facing the first gear 65. The rack 66 slides in the fixed bar 64. The first gear 65 is meshed and connected to the corresponding rack 66. A second motor 61 is installed at the lower end of the two fixed bars 64 through a mounting plate. A second gear 67 is installed at the top of the second motor 61 through an axle rod. The second gear 67 is meshed with the two fixed bars 64. Guide grooves 641 are opened along the length direction between the opposite sides of the two fixed bars 64. A guide bar 661 that slides in the guide groove 641 is fixed on the side of the rack 66 that is away from the first gear 65.

[0051] Through the above, when the larger peppers cannot pass through the flattening component 3, the larger peppers are guided to the inner side of the hopper 2 through the large pepper guide plate 35. The operator can decide whether to take further measures by observing the situation of the peppers passing through the flattening component 3. Due to the large size of the large peppers, congestion or inability to pass smoothly may occur during the guiding process. At this time, it is necessary to regularly start the second motor 61 to drive the second gear 67 to rotate. When the second gear 67 rotates, the two racks 66 meshing therewith will move relative to each other. Specifically, the racks 66 on both sides will rotate in opposite directions. This movement directly drives the movable baffles 7 on both sides to open or close synchronously. Through this design, when the large pepper passage 34 is opened, the large pepper can pass smoothly, allowing the large pepper to pass more smoothly during the entire guiding process, which not only improves the guiding efficiency, but also avoids the blockage problem caused by the excessive size of the peppers. It has high practical value in the actual pepper conveying and material distribution process.

[0052] Example 2: Please refer to Fig.11As shown, this embodiment is an extension of Embodiment 1: a plurality of balls are rollingly installed on the inner wall of the guide groove 641, and the end of the guide strip 661 contacts the balls. The plurality of rollingly installed balls can convert the sliding friction between the guide strip 661 and the guide groove 641 into the rolling friction of the balls, thereby reducing the friction. Moreover, the presence of the balls makes the movement of the end of the guide strip 661 in the guide groove 641 smoother and more precise, because the balls can fine-tune the movement of the guide strip 661 to a certain extent, reducing the movement deviation caused by uneven friction or uneven surface of the components.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0054] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
