[0002] In the process of agricultural product processing and handling, screening of agricultural products is an important link. Traditional screening methods mainly rely on manual labor, which is inefficient, and the screening results are easily affected by human factors, resulting in inaccurate and unstable screening results. With the development of industrial technology, screening devices for automatic screening of materials have emerged. When the screening device is working, in order to improve the working efficiency of the screening device and reduce the workload of the screening device, the agricultural products will be pre-screened by the material transportation device during material transportation, and then screened by the screening device. For example, in the Chinese patent with the publication number "CN 217700158 U", a material transportation device for automatic screening of agricultural products for primary processing is disclosed. The device is provided with a rubber ring so that the through hole will not be damaged when it contacts the melons and fruits. The melons and fruits enter the cavity through the through hole. The melons and fruits are screened and classified according to the different sizes of the through holes on each movable roller. The melons and fruits in the cavity fall into the placement slot through the conveying pipeline. However, when the device pre-screens the agricultural products, the screening specifications cannot be adjusted in real time, and can only be screened by a structure with preset specifications. Therefore, the types of agricultural products suitable for this device are fixed and the scope of use is fixed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 7 As shown, the utility model provides the following technical solutions:

[0026] A material transport device for automatic screening of agricultural products, comprising two inclined material conveying racks 7, with a material guide trough 18 formed on opposite sides of the two material conveying racks 7 for guiding the rolling of agricultural products;

[0027] The material transport device also includes a driving assembly, which includes two rotatably meshed gears 3. One side of two feed racks 7 is respectively fixedly connected to the top of the gears 3, and a drop trough for agricultural products to fall is formed between the two feed racks 7. The distance between the two feed racks 7 is expanded or reduced by rotating the gears 3, and the horizontal height of the feed rack 7 close to the gear 3 is lower than the horizontal height of the other side.

[0028] Through the above technical solution, when personnel need to transport agricultural products, the gear 3 is rotated to drive the two feed racks 7 to rotate, thereby adjusting the distance between the two feed racks 7, and the drop trough between the two feed racks 7 gradually expands from one side close to the gear 3 to the other side. When the distance between the two feed racks 7 is adjusted, the agricultural products to be transported are added between the two feed racks 7. Since the two feed racks 7 are tilted, the agricultural products will roll from a high place to a low place. When the agricultural products roll, the drop trough between the two feed racks 7 gradually expands. When the agricultural products pass through the drop trough, small-sized agricultural products to large-sized agricultural products gradually fall through the drop trough, and the agricultural products that do not pass through the drop trough are discharged through the very end of the feed rack 7, so that the agricultural products that meet the needs of the personnel enter the screening machine for screening, and the agricultural products that do not meet the needs fall below the two feed racks 7.

[0029] In addition, in the present invention, in order to support the gear 3, as shown in FIG. Figure 1-Figure 4 As shown, the material transport device includes a top plate 4, and support plates 1 are fixedly connected to the top of the top plate 4 on both symmetrical sides. The bottoms of two gears 3 are rotatably connected to the top of the top plate 4, and a motor 2 is fixedly connected to the bottom of the top plate 4. The output end of the motor 2 is connected to one of the gears 3.

[0030] In this embodiment, the top plate 4 and the support plate 1 are placed in a stable position, the top plate 4 is supported by the support plate 1, and the gear 3 is supported by the top plate 4. When personnel need to transport agricultural products, the gear 3 is driven to rotate by the motor 2, and the gear 3 drives the two feed racks 7 to rotate, thereby adjusting the distance between the two feed racks 7, and the drop groove between the two feed racks 7 gradually expands from one side close to the gear 3 to the other side. When the distance between the two feed racks 7 is adjusted, the agricultural products to be transported are added between the two feed racks 7. Since the two feed racks 7 are inclined, the agricultural products will roll from a high place to a low place. When the agricultural products roll, the drop groove between the two feed racks 7 gradually expands. When the agricultural products pass through the drop groove, small-sized agricultural products to large-sized agricultural products gradually fall through the drop groove, and the agricultural products that do not pass through the drop groove are discharged through the very end of the feed rack 7, so that the agricultural products that meet the needs of the personnel enter the screening machine for screening, and the agricultural products that do not meet the needs fall below the two feed racks 7.

[0031] When personnel need to screen agricultural products, in order to facilitate the addition of agricultural products between the two feeding racks 7, as shown in FIG. Figure 1-Figure 4 As shown, a feed hopper 6 is arranged above the two feed racks 7 , and a support rod 5 is fixedly connected between the peripheral surface of the feed hopper 6 and the top of the top plate 4 .

[0032] In this embodiment, the top plate 4 supports the support rods 5, and the support rods 5 support the feed hopper 6. When a person places agricultural products on the two conveyor racks 7, the agricultural products to be transported are placed in the feed hopper 6, and the agricultural products are guided by the feed hopper 6 to fall between the two conveyor racks 7. The agricultural products can then be transported and screened through the two conveyor racks 7.

[0033] When the feeding frame 7 rotates, in order to make the feeding frame 7 rotate more smoothly, Figure 1-Figure 4 and Figure 6 As shown, the feed frame 7 is symmetrically fixedly connected to side plates 16 on both sides, the bottom of the side plates 16 is fixedly connected to the bottom of the bottom rod 14, the bottom of the bottom rod 14 is fixedly connected to the bottom of the bottom frame 15, and the bottom of the bottom frame 15 is rotatably connected to a rolling ball 17.

[0034] In this embodiment, the base frame 15 is supported by the rolling ball 17, and the base frame 15 supports the bottom rod 14. When the gear 3 drives the feed frame 7 to rotate, the rolling ball 17 rolls, thereby making the feed frame 7 rotate more smoothly.

[0035] After the device screens the agricultural products, in order to facilitate the acceptance of agricultural products, such as Figure 1-Figure 3 , Figure 5 and Figure 7 As shown, a storage member is provided below the feeding frame 7, and the top of the storage member is opened to form a storage space for storing agricultural products that pass through the drop chute.

[0036] In this embodiment, after the agricultural products pass through the two feeding racks 7 through the drop chute, the agricultural products are received by the storage space on the storage member, and then the agricultural products are stored, so as to facilitate the collection of agricultural products that do not meet the specifications.

[0037] Specifically, in one embodiment, regarding the above-mentioned storage unit:

[0038] like Figure 1-Figure 3 , Figure 5 , Figure 7 As shown, the storage member includes a storage box 13 , and the top of the storage box 13 is opened to form a material storage cavity 8 .

[0039] In this embodiment, agricultural products are stored in the storage cavity 8 on the storage box 13 .

[0040] When agricultural products are stored in the storage cavity 8 on the storage box 13, in order to allow the storage box 13 to store agricultural products according to their specifications, such as Figure 1-Figure 3 , Figure 5 , Figure 7As shown, the storage box 13 has side rods 9 fixedly connected to both sides of the outer wall symmetrically, and a plurality of movable partitions are provided between the two side rods 9. A partition cavity for storing agricultural products is formed between two adjacent partitions. The partition includes a partition 10. The partition 10 has card plates 12 fixedly connected to both sides of the outer wall symmetrically, and the card plates 12 are provided with connecting grooves 11 matching the side rods 9.

[0041] In this embodiment, before storing agricultural products through the storage cavity 8 on the storage box 13, take the required number of partitions 10, place the partitions 10 inside the storage cavity 8, and make the partitions 10 engage with the side rods 9 through the connecting grooves 11 on the card plate 12, pull the partitions 10 to move them to the position required by the personnel, and then adjust the distance between two adjacent partitions 10. When storing agricultural products through the storage cavity 8 on the storage box 13, the agricultural products are stored through two adjacent partitions 10, and then the agricultural products that do not meet the specifications are classified and collected for easy later processing.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
