Technical Field
[0001] This utility model relates to the field of fruit and vegetable sorting technology, specifically to a fruit and vegetable feeding and sorting mechanism. Background Technology
[0002] With the development of modern society, mechanized and automated operations are constantly replacing manual labor. Before fruits and vegetables ripen and are sold on the market, they are usually sorted to remove those that are of different quality or spoiled. Fruit and vegetable sorting equipment typically clamps the fruit and vegetable sorting and conveying device onto the feeding component (such as a conveyor belt or gear belt) so that the fruits and vegetables can be transported through the feeding component and the fruit and vegetable sorting and conveying device to carry out a series of sorting operations.
[0003] However, due to the different weights of the fruits and vegetables they carry, the supporting structure of the existing fruit and vegetable sorting and conveying device may gradually tilt into an uneven state as it moves forward with the feeding component. Under the same external force, the supporting structure of each fruit and vegetable sorting and conveying device will flip outward in different directions. This makes it difficult to ensure that the fruits and vegetables on the fruit and vegetable sorting and conveying device can fall into the corresponding fruit and vegetable collection area or guide plate. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a fruit and vegetable sorting mechanism that can replace manual labor in the sorting process of harvested fruits and vegetables. It is particularly suitable for sorting melons and vegetables, with good sorting effect, and can ensure that the fruits and vegetables on the fruit and vegetable sorting and conveying device can fall smoothly into the corresponding fruit and vegetable collection area or guide plate, thereby improving sorting efficiency.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A fruit and vegetable feeding and sorting mechanism includes a frame, on which a feeding component is mounted. The feeding component has several fruit and vegetable sorting and conveying devices, each including a base fixed to the feeding component, a support structure movably connected to the base, and a roller assembly on the support structure. The support structure and the roller assembly together carry the fruits and vegetables. The frame also includes an external force pushing device located on either side of the feeding component. The external force pushing device includes a guide plate and a pushing assembly. The upper surface of the guide plate has a calibration plane and a transition slope connected to the calibration plane. The lower part of the support structure has a bottom plane. When the fruit and vegetable sorting and conveying device moves with the feeding component until the calibration plane and the bottom plane are in contact, the pushing assembly lifts the support structure and tilts it to the side away from the external force pushing device.
[0007] In the fruit and vegetable feeding and sorting mechanism described above, the calibration plane is located in the middle of the guide plate, and transition slopes are connected to both the front and rear sides of the calibration plane.
[0008] As described above, the fruit and vegetable feeding and sorting mechanism includes a pusher rod that extends and retracts vertically and a cylinder that drives the pusher rod. When the pusher rod extends upward, one side of the pusher support structure moves upward, causing the support structure to tilt to the side away from the pusher assembly.
[0009] As described above, the fruit and vegetable feeding and sorting mechanism is further provided with several sets of guide plates on the frame. The guide plates are located below the feeding component and are used to guide the fruits and vegetables that fall from the fruit and vegetable sorting and conveying device when the external force pushing device pushes the support structure.
[0010] As described above, the fruit and vegetable feeding and sorting mechanism includes a support structure that is movably connected to the base and two support arms that are respectively connected to the left and right ends of the support. The roller assembly is disposed between the two support arms.
[0011] As described above, the fruit and vegetable feeding and sorting mechanism has a protrusion on the support part and a support surface that slopes downwards from the protrusion to near the end of the support arm. The protrusion, the support surface, and the roller assembly together support the fruits and vegetables.
[0012] As described above, the fruit and vegetable feeding and sorting mechanism includes a roller assembly comprising a rotating shaft and two rollers disposed on the rotating shaft. The rotating shaft is rotatably connected to the support arm. The diameters of the two rollers gradually decrease from the mounting end near the rotating shaft towards the center, so that a concave bearing surface for bearing fruits and vegetables is formed between the two rollers.
[0013] As described above, the fruit and vegetable feeding and sorting mechanism includes a base comprising a clamping part fixed to the feeding component, a reinforcing part connected above the clamping part, and a mounting part disposed on the top of the reinforcing part. The supporting structure is movably connected to the mounting part. The fruit and vegetable sorting and conveying device further includes a U-shaped connector for connecting the supporting structure and the base. The mounting part has a cavity, and the connector is movably inserted into the cavity. Both ends of the connector are respectively connected to the two supporting arms.
[0014] As described above, the fruit and vegetable feeding and sorting mechanism has a tapered protrusion on the mounting part for supporting the connector upwards, and the protrusion is located inside the cavity; the top two sides of the mounting part are provided with limiting recesses, and the bottom two sides of the support part are provided with limiting protrusions that are adapted to the limiting recesses, and the limiting recesses abut against the limiting protrusions so that the support structure is fastened to the base.
[0015] As described above, the fruit and vegetable feeding and sorting mechanism has several mounting holes on the inner side of the support arm for mounting the rotating shaft.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] 1. This utility model of fruit and vegetable unloading and sorting mechanism can replace manual labor for sorting harvested fruits and vegetables. It has a good sorting effect and can ensure that the fruits and vegetables on the fruit and vegetable sorting and conveying device can fall smoothly into the corresponding fruit and vegetable collection area or guide plate, thereby improving sorting efficiency.
[0018] 2. This utility model provides a calibration plane and a transition slope connected to the calibration plane on the upper surface of the guide plate. The transition slope can smoothly transition the bottom plane of the support structure to the calibration plane, ensuring that the fruit and vegetable sorting and conveying device can be transported smoothly on the feeding component. When the pushing component lifts any support structure of the fruit and vegetable sorting and conveying device, the support structure flips to the side in the same direction, and the fruits and vegetables carried on the support structure are thrown out in the same direction and fall into the corresponding area.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0027] like Figure 1-2As shown, this utility model discloses a fruit and vegetable sorting and unloading mechanism, including a frame 1, a feeding component 2 on the frame 1, and several fruit and vegetable sorting and conveying devices 3 on the feeding component 2. The frame 1 is also equipped with a collection device (not shown), a visual inspection device (not shown), and a weighing device (not shown) to detect, weigh, and sort the fruits and vegetables on the conveying devices 3. Figure 3 , Figure 5-7 As shown, the fruit and vegetable sorting and conveying device 3 of this utility model includes a base 31 fixed to the feeding component 2, a support structure 32 movably connected to the base 31, and a roller assembly 33 located on the support structure 32 for rolling the fruits and vegetables. The support structure 32 and the roller assembly 33 jointly bear the fruits and vegetables. The frame 1 is also provided with an external force pushing device 4, which is located on either side of the feeding component 2. The external force pushing device 4 includes a guide plate 41 and a pushing assembly 42. The upper surface of the guide plate 41 has a calibration plane 411 and a transition slope 412 connected to the calibration plane 411. The lower part of the support structure 32 has a bottom plane 320. When the fruit and vegetable sorting and conveying device 3 moves with the feeding component 2 to the point where the calibration plane 411 and the bottom plane 320 are in contact, the pushing assembly 42 lifts the support structure 32 and flips it to the side away from the external force pushing device 4.
[0028] This utility model relates to a fruit and vegetable sorting mechanism, which is used to sort harvested fruits and vegetables. It is particularly suitable for sorting melons and vegetables, and has a good sorting effect. It can ensure that the fruits and vegetables on the fruit and vegetable sorting and conveying device can fall into the corresponding fruit and vegetable collection area or guide plate.
[0029] Specifically, the transition slope 412 abuts against a portion of the bottom plane 320 of the support structure 32, smoothly transitioning the bottom plane 320 to the calibration plane 411, so that the bottom plane 320 and the calibration plane 411 remain parallel. Under the action of the external force of the external force pushing device 4, one side of the support structure 32 is driven to tilt to the side away from the external force, so that the fruits and vegetables carried on the feeding component 2 can fall smoothly into the corresponding area.
[0030] Furthermore, the calibration plane 411 is located in the middle of the guide plate 41, and transition slopes 412 are connected to both its front and rear sides. This makes the external force pushing device 4 applicable to feeding components 2 that move forward or backward, thus broadening its applicability.
[0031] like Figure 4 As shown, the push assembly 42 in this embodiment of the present invention includes a push rod 421 that extends and retracts vertically and a cylinder 422 that drives the push rod 421 to move. The push rod 421 extends upward and moves upward to one side of the push support structure 32, causing the support structure 32 to flip to the side away from the push assembly 42.
[0032] like Figure 1-2As shown, the frame 1 of this utility model is also provided with several sets of guide plates 11. The guide plates 11 are located below the feeding component 2 and are used to guide the fruits and vegetables that fall from the fruit and vegetable sorting and conveying device 3 when the external force pushing device 4 pushes the support structure 32.
[0033] like Figure 3 and Figure 5-7 As shown, the support structure 32 includes a support part 321 that is movably connected to the base 31 and two support arms 322 that are respectively connected to the left and right ends of the support part 321. The roller assembly 33 is disposed between the two support arms 322.
[0034] like Figure 5-6 As shown, the support portion 321 of this utility model has a protrusion 3211, and the support portion 321 has a support surface 3212 that slopes downwards from the protrusion 3211 to near the end of the support arm 322. The protrusion 3211, the support surface 3212, and the roller assembly 33 together support the fruits and vegetables. In this embodiment, the protrusion 3211 and the roller assembly 33 respectively contact multiple parts of the fruits and vegetables, increasing the contact area between the support structure 32 and the fruits and vegetables. The downwardly sloping support surface 3212 enhances the adhesion effect of the support structure 32 and the roller assembly 33 on the fruits and vegetables. In addition, by setting the protrusion 3211, the probability of collision between the fruits and vegetables and the support structure 32 during transportation is reduced by the fruit and vegetable sorting and conveying device 3, greatly reducing the phenomenon of fruit damage.
[0035] Specifically, the roller assembly 33 in this embodiment includes a rotating shaft 331 and two rollers 332 mounted on the rotating shaft 331. The rotating shaft 331 is rotatably connected to the support arm 322. The diameter of the two rollers 332 gradually decreases from the mounting end near the rotating shaft 331 towards the center, so that a concave bearing surface 3321 for carrying fruits and vegetables is formed between the two rollers 332. The concave bearing surface 3321 further increases the contact area with fruits and vegetables and the adhesion effect, allowing fruits and vegetables to be better placed within the bearing structure formed by the concave bearing surface 3321 and the inclined support surface 3212, making the fruit and vegetable sorting and conveying device 3 more stable during transportation and preventing it from falling off the support structure 32.
[0036] like Figure 6As shown in Figure 7, the base 31 of this utility model includes a clamping part 311 fixed to the feeding component 2, a reinforcing part 312 connected above the clamping part 311, and a mounting part 313 disposed on the top of the reinforcing part 312. The support structure 32 is movably connected to the mounting part 313. The reinforcing part 312 is connected to the top of the clamping part 311, which increases the yield strength of the base 31 and greatly improves the clamping force of the clamping part 311 on the feeding component 2. This prevents the fruit and vegetable sorting and conveying device 3 from shaking or even falling due to insufficient clamping force of the clamping part 311 during the conveying of fruits and vegetables, thus avoiding damage to the fruits and vegetables from accidental falling and ensuring that the fruits and vegetables smoothly complete the sorting process under the conveying of the fruit and vegetable sorting and conveying device 3.
[0037] In this embodiment of the utility model, the fruit and vegetable sorting and conveying device 3 also includes a U-shaped connector 34 for connecting the support structure 32 and the base 31. The mounting part 313 has a cavity 3131, and the connector 34 is movably inserted into the cavity 3131. The two ends of the connector 34 are connected to the two support arms 322 one by one.
[0038] like Figure 7 As shown, in this embodiment, the mounting part 313 is provided with a protrusion 3132 for supporting the connecting member 34 upwards, located inside the cavity 3131; the top two sides of the mounting part 313 are provided with limiting recesses 3133, and the bottom two sides of the support part 321 are provided with limiting protrusions 3213 that are adapted to the limiting recesses 3133. The limiting recesses 3133 abut against the limiting protrusions 3213, so that the support structure 32 is fastened to the base 31. The weight of the fruits and vegetables acts on the support structure 32, and through the limiting protrusions 3213 on the support structure 32, it acts on the limiting recesses 3133, thereby making the support structure 32 more stably fastened to the base 31, preventing the support structure 32 from tilting or even falling off due to uneven force, so that the support structure 32 can smoothly transport fruits and vegetables.
[0039] When unloading the fruit, the external force pushing device 4 usually applies a vertical upward force to the support arm 322 of the support structure 32, so that the limiting protrusion 3213 disengages from the limiting recess 3133. Under the action of the external force pushing device 4, the support arm 322 drives the support structure 32 to tilt away from the base 41 to the side away from the external force pushing device 4, so that the fruit and vegetables fall off the support structure 32.
[0040] Furthermore, such as Figure 6 As shown, the inner side of the support arm 322 is provided with a number of mounting holes 3221 for mounting the rotating shaft 331. By adjusting the mounting position of the roller assembly 33 on the support arm 322, the distance between the roller assembly 33 and the support part 321 can be adjusted. The size of the recessed structure for placing fruits and vegetables on the support structure 32 can be controlled by the distance, so as to prevent small fruits and vegetables from falling out of the gap between the roller assembly 33 and the support part 321.
