Description

Technical Field

[0001] This utility model belongs to the field of sorting machine technology, and in particular relates to an agricultural product sorting machine. Background Technology

[0002] Agricultural product sorting machines utilize principles such as weight, size, and optics, and through the coordinated work of multiple components, they automatically grade and screen agricultural products, thereby improving their commercial value and production efficiency.

[0003] Traditional sorting requires manual labor to continue complex, tedious, and repetitive mechanical work, which can lead to worker fatigue over time. When sorting large volumes, workers are also prone to fatigue, resulting in incomplete sorting. Furthermore, most sorting machines on the market can only perform single-stage sorting, limiting their application scope.

[0004] Existing patent (application number: CN202323236093.1) discloses a multi-stage sorting mechanism and an agricultural product sorting machine based on this mechanism. When crops enter the second housing, they first contact the primary sorting roller. At this time, the primary sorting roller rotates continuously, conveying the crops above to the secondary sorting roller. Because the primary sorting roller has multiple first sorting holes, when crops smaller than the diameter of the first sorting hole pass through the primary sorting roller, they will fall through the first sorting hole to complete the primary sorting. When the crops after primary sorting pass through the secondary sorting roller, those smaller than the diameter of the first sorting hole will fall through the first sorting hole to complete the primary sorting. Crops with a diameter smaller than the second sorting hole will fall through the second sorting hole to complete the secondary sorting. When the crops that have completed the secondary sorting pass through the third sorting roller, crops smaller than the diameter of the third sorting hole will fall through the third sorting hole to complete the tertiary sorting. In particular, the number and types of the first, second, and third sorting rollers can be set to make the sorting more complete and accurate. After the sorting is completed, the crops will be driven into the storage box by the third sorting roller. After confirming that the crops in the storage box are correctly graded, the remaining ones are the premium grade fruits, realizing automated multi-level sorting.

[0005] To address the aforementioned problems, existing patents have provided solutions. However, in the actual sorting process, the structure of these devices is complex, making it difficult to adjust the sorting size standards according to the size of different types of agricultural products. For example, when there is a large size difference between apples and oranges, all the oranges will fall during the first sorting. This needs to be improved. Therefore, an agricultural product sorting machine is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an agricultural product sorting machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an agricultural product sorting machine, comprising a base, on which symmetrical supports are fixedly installed, and a conveying pipe is fixedly installed between the two sets of supports.

[0010] As a further description of the above solution: by setting up the coordinated operation of the arc plate, the contraction section, the spring, and the pressure plate, the stability of the arc plate on the conveying pipe can be significantly enhanced, thereby ensuring the stability of agricultural product sorting.

[0011] Preferably, the bottom end of the arc plate extends through the end of the conveying pipe.

[0012] As a further description of the above solution: the bottom end of the arc plate passes through the end of the conveying pipe, which makes it convenient for the operator to hold the end of the arc plate and push or pull the arc plate to slide and adjust it on the conveying pipe, thereby improving the convenience of operation.

[0013] Preferably, the inclination of the conveying pipe is set between 25° and 35°.

[0014] As a further description of the above solution: the inclination of the conveying pipe is set between 25° and 35°, which can prevent the crops from rolling too fast and affecting the sorting effect.

[0015] Preferably, the base has evenly distributed placement openings, the number of placement openings is the same as the number of collection boxes, and the bottom size of the collection box is adapted to the size of the placement openings.

[0016] As a further description of the above solution: setting up a placement opening facilitates the placement of the collection box and ensures the stability of the collection box collection.

[0017] Preferably, the feeding hopper is vertically fixedly connected to the top of the conveying pipe.

[0018] As a further description of the above solution: the feeding hopper is vertically fixed to the top of the conveying pipe to facilitate the feeding of agricultural products.

[0019] Preferably, the top end of the conveying pipe is threaded with a top cover.

[0020] As a further description of the above solution: the top of the conveying pipe is threaded with a top cover, which can open the top of the feeding hopper.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-9 This utility model provides a technical solution:

[0037] An agricultural product sorting machine includes a base 1, on which symmetrical supports 2 are fixedly installed. A conveying pipe 3 is fixedly installed between the two sets of supports 2. Both the supports 2 and the conveying pipe 3 are inclined. A feeding hopper 4 is fixedly connected to the top of the conveying pipe 3. A sorting port 5 is opened on the bottom surface of the conveying pipe 3. Symmetrical arc plates 6 are slidably arranged on the conveying pipe 3. Damping is provided between the arc plates 6 and the conveying pipe 3. The bottom edges of the two sets of arc plates 6 are both located inside the sorting port 5, and the distance between the bottom edges of the two sets of arc plates 6 gradually increases from top to bottom. The bottom end of the conveying pipe 3 is provided with graduations on the sides of the two sets of arc plates 6. Evenly distributed collection boxes 7 are provided on the base 1, and the collection boxes 7 are all located below the sorting port 5.

[0038] In use, the base 1 and the bracket 2 support the entire device. When sorting agricultural products, the operator pulls or pushes the arc plate 6 to move on the conveying pipe 3. Since there is damping between the arc plate 6 and the conveying pipe 3, the arc plate 6 can be stably stopped in the corresponding position after moving. According to the size of the agricultural products, the distance between the bottom edges of the two sets of arc plates 6 is adjusted. The bottom of the conveying pipe 3 is set with scales on the sides of the two sets of arc plates 6 to facilitate the symmetrical adjustment of the two sets of arc plates 6. Since the distance between the bottom edges of the two sets of arc plates 6 gradually increases from top to bottom, agricultural products of different sizes can be sorted.

[0039] After the two sets of arc plates 6 are adjusted, the agricultural products are fed through the feeding hopper 4. Since the conveying pipe 3 is set to be inclined, the agricultural products will automatically roll down along the conveying pipe 3. During the rolling process, they pass through the sorting port 5 and the two sets of arc plates 6 at the sorting port 5. When the size of the agricultural products is smaller than the distance between the corresponding positions of the bottom edges of the two sets of arc plates 6, they will fall from the sorting port 5 and fall into the collection box 7 below the sorting port 5 for collection.

[0040] This agricultural product sorting machine can easily adjust the sorting size standard according to the size of different types of agricultural products, effectively enhancing the versatility and practicality of the device.

[0041] A contraction section 8 is provided on the side of the arc plate 6. A spring 9 is evenly distributed inside the contraction section 8. A pressure plate 10 is slidably arranged on the arc plate 6 at the contraction section 8. The two ends of the spring 9 are fixedly installed to the arc plate 6 and the pressure plate 10 respectively, and the spring 9 is pressed between the arc plate 6 and the pressure plate 10. The pressure plate 10 is in contact with the conveying pipe 3.

[0042] When the arc plate 6 slides and adjusts on the conveying pipe 3, the spring 9 is always pressed between the arc plate 6 and the pressure plate 10, so that the pressure plate 10 and the conveying pipe 3 are in close contact. The pressure provided by the spring 9 ensures that the position of the arc plate 6 on the conveying pipe 3 is fixed, which significantly enhances the stability of the arc plate 6 on the conveying pipe 3, thereby ensuring that the position of the arc plate 6 remains unchanged during the sorting of agricultural products and ensuring the stability of sorting.

[0043] The bottom end of the arc plate 6 passes through the end of the conveying pipe 3;

[0044] The bottom end of the arc plate 6 passes through the end of the conveying pipe 3. When adjusting the size standard for sorting agricultural products, the operator can easily hold the end of the arc plate 6 and slide the arc plate 6 on the conveying pipe 3 by pushing or pulling the end of the arc plate 6, which improves the convenience of operation.

[0045] The inclination of the conveying pipe 3 is set between 25° and 35°.

[0046] The inclination of the conveyor pipe 3 is set between 25° and 35°, which allows the agricultural products to slide down at a moderate speed, avoids the crops from rolling too fast, and ensures that agricultural products of different sizes have enough time to fall from the sorting port 5 at the appropriate sorting position, thereby improving the accuracy of sorting.

[0047] The base 1 has evenly distributed placement openings 11. The number of placement openings 11 is the same as the number of collection boxes 7, and the bottom size of the collection box 7 is adapted to the size of the placement openings 11.

[0048] The number of placement openings 11 on the base 1 is the same as the number of collection boxes 7, and the bottom size of the collection box 7 is adapted to the size of the placement opening 11. When the collection box 7 is placed in the placement opening 11, the edge of the placement opening 11 plays a limiting role on the collection box 7, preventing the collection box 7 from shaking or shifting when receiving agricultural products falling from the sorting opening 5.

[0049] The feeding hopper 4 is vertically and fixedly connected to the top of the conveying pipe 3;

[0050] The feeding hopper 4 is vertically fixed to the top of the conveying pipe 3, which facilitates the feeding of agricultural products.

[0051] The top of the conveying pipe 3 is threadedly connected to a top cover 12;

[0052] The top of the conveying pipe 3 is threaded with a top cover 12. When agricultural products become blocked at the connection between the feeding hopper 4 and the conveying pipe 3, the operator can open the top of the feeding hopper 4 by rotating the top cover 12. After opening, the connection between the conveying pipe 3 and the feeding hopper 4 can be directly observed and cleared. Tools can be used to remove the blocked agricultural products to avoid affecting the normal progress of the feeding process and sorting work due to blockage.

[0053] Working principle:

[0054] In use, the base 1 and the bracket 2 support the entire device. When sorting agricultural products, the operator pulls or pushes the arc plate 6 to move on the conveying pipe 3. Since there is damping between the arc plate 6 and the conveying pipe 3, the arc plate 6 can be stably stopped in the corresponding position after moving. According to the size of the agricultural products, the distance between the bottom edges of the two sets of arc plates 6 is adjusted. The bottom of the conveying pipe 3 is set with scales on the sides of the two sets of arc plates 6 to facilitate the symmetrical adjustment of the two sets of arc plates 6. Since the distance between the bottom edges of the two sets of arc plates 6 gradually increases from top to bottom, agricultural products of different sizes can be sorted.

[0055] After the two sets of arc plates 6 are adjusted, the agricultural products are fed through the feeding hopper 4. Since the conveying pipe 3 is set to be inclined, the agricultural products will automatically roll down along the conveying pipe 3. During the rolling process, they pass through the sorting port 5 and the two sets of arc plates 6 at the sorting port 5. When the size of the agricultural products is smaller than the distance between the corresponding positions of the bottom edges of the two sets of arc plates 6, they will fall from the sorting port 5 and fall into the collection box 7 below the sorting port 5 for collection.

[0056] This agricultural product sorting machine can easily adjust the sorting size standard according to the size of different types of agricultural products, effectively enhancing the versatility and practicality of the device;

[0057] in,

[0058] When the arc plate 6 slides and adjusts on the conveying pipe 3, the spring 9 is always pressed between the arc plate 6 and the pressure plate 10, so that the pressure plate 10 and the conveying pipe 3 are in close contact. The pressure provided by the spring 9 ensures that the position of the arc plate 6 on the conveying pipe 3 is fixed, which significantly enhances the stability of the arc plate 6 on the conveying pipe 3, thereby ensuring that the position of the arc plate 6 remains unchanged during the sorting of agricultural products and ensuring the stability of sorting.

[0059] The bottom end of the arc plate 6 passes through the end of the conveying pipe 3. When adjusting the size standard for sorting agricultural products, the operator can easily hold the end of the arc plate 6 and slide the arc plate 6 on the conveying pipe 3 by pushing or pulling the end of the arc plate 6, which improves the convenience of operation.

[0060] The inclination of the conveyor pipe 3 is set between 25° and 35°, which can make the downward speed of agricultural products moderate, avoid the crops rolling too fast, and ensure that agricultural products of different sizes have enough time to fall from the sorting port 5 at the appropriate sorting position, thereby improving the accuracy of sorting.

[0061] The number of placement openings 11 on the base 1 is the same as the number of collection boxes 7, and the bottom size of the collection box 7 is adapted to the size of the placement opening 11. When the collection box 7 is placed in the placement opening 11, the edge of the placement opening 11 plays a limiting role on the collection box 7, preventing the collection box 7 from shaking or shifting when receiving agricultural products falling from the sorting port 5.

[0062] The hopper is vertically and fixedly connected to the top of the conveying pipe 3 to facilitate the feeding of agricultural products;

[0063] The top of the conveying pipe 3 is threaded with a top cover 12. When agricultural products become blocked at the connection between the feeding hopper 4 and the conveying pipe 3, the operator can open the top of the feeding hopper 4 by rotating the top cover 12. After opening, the connection between the conveying pipe 3 and the feeding hopper 4 can be directly observed and cleared. Tools can be used to remove the blocked agricultural products to avoid affecting the normal progress of the feeding process and sorting work due to blockage.

[0064] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
