Description

Technical Field

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

[0002] In recent years, garlic has gained increasing popularity and attention due to its unique health benefits and rich nutritional content, leading to a continuous increase in market demand. Furthermore, the rising economic value of garlic cultivation has spurred farmers to grow it, further expanding the scale of garlic planting. Against this backdrop, China's garlic industry has developed rapidly, and today China has become the world's largest producer, consumer, and exporter of garlic.

[0003] The main markets for garlic are currently export trade and large supermarkets. However, market demand has different requirements for garlic of different grades and specifications. Although large-scale growers usually hire specialized sorting workers to grade garlic, manual sorting of garlic has a series of problems such as low efficiency, time-consuming, labor-intensive, costly and inaccurate. In addition, the sorting process will mix in dust, mud and broken garlic cloves, and sometimes even onion-shaped garlic that cannot be identified with the naked eye, which greatly reduces the quality of packaged garlic. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a garlic sorting device, the technical solution of which is as follows:

[0005] A garlic sorting device includes a pre-sorting mechanism, a grading roller mechanism, and an onion-shaped garlic screening mechanism. The pre-sorting mechanism includes a sorting base frame, a sorting support frame above the sorting base frame, and the two are connected by a spring. A feeding hopper is installed above the sorting support frame, a vibrating motor is installed below the sorting support frame, and a sieve plate is installed in the sorting support frame.

[0006] The grading roller mechanism includes a roller base frame, with a pair of support wheels at each end of the roller base frame for supporting the roller. The roller is composed of five cylindrical sections, each of which contains blades. A common main shaft passes through multiple blades. A sprocket is installed at one end of the main shaft, and the sprocket is connected to a drive motor mounted on a motor bracket via a chain. A discharge hopper is provided below each cylindrical section, and an onion-shaped garlic screening mechanism is provided below each corresponding discharge hopper.

[0007] The onion-shaped garlic screening mechanism includes a conveyor belt base frame, a conveyor belt installed in the conveyor belt base frame, a conveyor belt motor installed on one side of the conveyor belt base frame, two grooves provided above the conveyor belt base frame, a baffle is movably installed in one groove, a collection bin is installed on the outside of the other groove, and a cylinder connected to the baffle is installed on one side of the groove.

[0008] Furthermore, a weighing sensor is installed in the conveyor belt base frame. This weighing sensor can detect onion-shaped garlic mixed in with normal garlic. In conjunction with the cylinder and baffle, onion-shaped garlic can be automatically separated to ensure the final quality of the product.

[0009] Furthermore, a discharge hopper is provided on one side of the sorting bracket, which can discharge the crushed garlic and impurities screened out in the pre-sorting mechanism.

[0010] Furthermore, a bearing seat bracket is provided at one end of the roller base frame, and a motor bracket is provided at the other end of the roller base frame. A bearing seat for connecting the main shaft is installed above the bearing seat bracket. Another bearing seat is also provided at the other end of the main shaft where the sprocket is located. The main shaft is supported by the two bearing seats together to ensure stable operation of the roller.

[0011] Furthermore, the spacing between the grid bars in each section of the cylinder is different, with the specific gap increasing progressively from one end near the pre-sorting mechanism towards the other, in order to accommodate the grading requirements of garlic of different sizes and achieve precise grading of garlic.

[0012] Furthermore, the roller base is tilted, with one end near the pre-sorting mechanism slightly higher than the other end of the roller base, so that the garlic gradually moves towards the other end of the grading roller during the rolling process, ensuring the grading effect.

[0013] Furthermore, the discharge hopper is equipped with partition plates on both sides to prevent the garlic from being remixed after grading, which would affect the sorting accuracy.

[0014] Furthermore, the baffle is provided with a sliding groove, and a vertical rod is provided at the connection between the cylinder's extension rod and the sliding groove. The vertical rod can slide in the sliding groove. In use, the baffle can be rotated by extending and retracting the cylinder.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention effectively separates impurities and broken garlic from garlic through a pre-sorting mechanism. After sorting, the garlic enters a drum, where centrifugal force and an inclined design are used to grade the garlic by size. Finally, onion-shaped garlic is further screened out in the onion-shaped garlic screening mechanism and collected separately. Compared with manual screening, this device significantly improves sorting efficiency and accuracy, reduces labor costs and labor intensity, and ensures the consistency of the final product quality.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] As attached Figure 1-9 As shown.

[0030] A garlic sorting device includes a pre-sorting mechanism, a grading roller mechanism, and an onion-shaped garlic screening mechanism. The pre-sorting mechanism includes a sorting base frame 10, with a sorting support frame 11 above the base frame 10, connected by a spring. A feed hopper 12 is installed above the sorting support frame 11, and a vibration motor 13 is installed below the support frame 11. A screen plate 14 is installed in the support frame 11, which is 5-10 cm higher than the bottom surface of the support frame 11 during installation. Under the action of the vibration motor 13, the screen plate 14 generates high-frequency vibration, separating the garlic from impurities. The impurities fall through the mesh of the screen plate 14 into the bottom of the sorting support frame 11 and are discharged from the discharge hopper 15 on one side of the support frame 11. The garlic slides down the screen plate 14 from one end of the sorting support frame 11 into the roller 27 of the grading roller mechanism.

[0031] The roller 27 is placed above the roller base 20. A pair of support wheels 26 for supporting the roller 27 are respectively provided at both ends of the roller base 20, as shown in the attached figure. Figure 5 , 6 As shown; the roller 27 is composed of five cylindrical sections, each with different spacing between the grid bars, and the specific spacing increases sequentially from one end near the pre-sorting mechanism toward the other end.

[0032] Each cylindrical section is provided with blades 28, and a common main shaft 25 passes through multiple blades 28; a bearing seat bracket 21 is provided at one end of the drum base frame 20, and a motor bracket 22 is provided at the other end of the drum base frame 20. One end of the main shaft 25 is connected to the bearing seat on the bearing seat bracket 21, and a sprocket 24 is installed at the other end of the main shaft 25. The sprocket 24 is connected to the drive motor 23 installed on the motor bracket 22 via a chain.

[0033] Furthermore, the roller base 20 is tilted, with the end near the pre-sorting mechanism slightly higher than the other end of the roller base 20. Based on the above structure, after the drive motor 23 starts, it will drive the main shaft 25, blades 28 and roller 27 to rotate together through the connection between the chain and sprocket 24. Under the action of centrifugal force, garlic that matches the size of the grid gap will fall from the gap. Under the action of the tilt of the roller 27, the garlic in the roller 27 will gradually move towards the end away from the pre-sorting mechanism. When passing through the five sections of the cylinder, garlic of different thicknesses and sizes will be screened in sequence.

[0034] A discharge hopper 210 is provided at the bottom of each cylindrical section, and a partition plate 29 is provided on both sides of each discharge hopper 210. The garlic that is screened by the grid in the cylinder will fall above the discharge hopper 210 and slide down to the top of the onion-shaped garlic screening mechanism on one side.

[0035] The onion-shaped garlic screening mechanism includes a conveyor belt base 30, in which a conveyor belt 32 is installed to receive garlic falling from the discharge hopper 210. A conveyor belt motor 31 for driving the conveyor belt 32 to rotate is installed on one side of the conveyor belt base 30. Two grooves are provided above the conveyor belt base 30. A baffle 35 is movably installed in one groove, and a collection hopper 33 is installed on the outside of the other groove. A cylinder 34 is installed on one side of the groove, and the telescopic rod of the cylinder 34 is movably connected to the baffle 35.

[0036] Specifically, as shown in the attached document Figure 9 As shown, a groove 36 is provided in the baffle 35, and a vertical rod is provided at the position of the telescopic rod in the groove 36 for sliding within the groove 36. In use, the baffle 35 can be rotated by extending and retracting the cylinder 34.

[0037] The working principle of this device is as follows: garlic is poured into the pre-sorting device from the feed hopper 12. After entering, the vibrating motor 13 drives the screen plate 14 to screen. During the vibration of the screen plate 14, the broken garlic and soil can be screened off and fall below the screen plate 14 along with the impurities. Finally, the garlic is discharged from the pre-sorting mechanism from the discharge hopper 15.

[0038] After screening, intact garlic enters the grading drum 27 of the sorting drum mechanism through the opening of the sorting bracket. Driven by the drive motor 23, the drum 27 rotates together with the main shaft 25 and blades 28. Due to centrifugal force and the inclined setting of the drum base 20, garlic of different thicknesses and sizes falls through the gaps in the corresponding cylindrical grid bars during movement. The fallen garlic then passes through the discharge hopper 210 to the corresponding gaps in the grid 17 below, falling through the corresponding gaps and finally into the onion-shaped garlic screening mechanism below, as shown in the attached diagram. Figure 7 As shown, a weighing sensor 37 is installed in the conveyor belt base frame 30. Since the weight of onion-shaped garlic is different from that of ordinary garlic, after the weighing sensor 37 senses the onion-shaped garlic, it will transmit information to the PLC, controlling the cylinder 34 to retract and the baffle 35 to rotate to the attached position. Figure 8 As shown, the onion-shaped garlic cloves fall into the collection hopper 33 under the guidance of the baffle 35. Immediately afterwards, the cylinder 34 extends again, restoring its attachment position. Figure 7 This condition allows the remaining normal garlic to be transported to the end of the conveyor belt 32 for collection.

[0039] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
