Description

Technical Field

[0001] This utility model relates to the field of dragon fruit sorting technology, specifically to an automatic dragon fruit sorting and size classification device for dragon fruit cultivation. Background Technology

[0002] Dragon fruit, with its rich nutritional value and unique appearance, is widely popular in domestic and international markets and has become one of the important economic crops in tropical and subtropical regions. With the continuous expansion of dragon fruit planting scale and the increasing demands of consumers for fruit quality, how to efficiently and accurately grade dragon fruit after harvesting has become a key factor affecting its commodity value and market competitiveness.

[0003] However, existing sorting devices have the following problems when in use: Existing sorting devices usually use a conveyor track and positioning tilting method for feeding. After the dragon fruit is graded, it slides down the inclined guide plate to the collection box below by gravity. However, during operation, when it is necessary to replace the collection box that is full, the grading operation of that grade often needs to be temporarily interrupted. However, due to the difficulty in accurately controlling the discharge rhythm, some dragon fruit will continue to slide down the inclined guide plate. At this time, there is no effective transition receiving mechanism or stopping mechanism. These fruits will fall directly to the ground, which not only causes fruit to be bumped and damaged, increasing losses, but also affects the cleanliness and safety of the working environment, and disrupts the continuity and smoothness of the sorting process, which is not conducive to achieving efficient and automated continuous operation. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an automatic dragon fruit sorting and size classification device for dragon fruit cultivation, which can automatically close the discharge port when changing frames, making it convenient to use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic dragon fruit sorting and size classification device for dragon fruit cultivation includes a frame and a base plate. A conveying device is installed on the frame, and mounting plates are installed at equal intervals on the conveying device. A flipping weighing box is rotatably installed on the mounting plate. Discharge ports are fixedly installed at equal intervals on the side of the frame, and flipping baffles are rotatably installed on multiple discharge ports. The number of base plates is the same as the number of discharge ports, and the base plates are located directly below the corresponding discharge ports. Multi-stage telescopic rods are installed on multiple base plates, and a placement plate is fixedly installed at the other end of the multi-stage telescopic rods. A collection mechanism is provided on the placement plate, and a drive mechanism is provided on the discharge port.

[0006] Preferably, the collecting mechanism includes a collecting frame, a sliding side plate is slidably installed on the side of the collecting frame facing the discharge port, the sliding side plate is located directly below the discharge port, the collecting frame has an exposed through groove adapted to the sliding side plate, the placement plate has an alignment groove adapted to the sliding side plate, and both the collecting frame and the sliding side plate have gripping grooves.

[0007] Preferably, a support plate is fixedly installed on the base plate, and the support plate can directly abut against the flipping blocking plate.

[0008] Preferably, sliders are fixedly installed on both sides of the sliding side plate, and the collection frame has grooves at corresponding positions for the sliders to slide.

[0009] Preferably, a positioning cavity adapted to the collection frame is provided on the placement plate.

[0010] Preferably, the drive mechanism includes a mounting shaft and a mounting rod. The mounting shaft is fixedly mounted on the drive shaft of the tilting baffle plate. A passive toothed plate is fixedly mounted on the mounting shaft through the discharge port. The mounting rod is fixedly mounted on the placement plate. An active toothed plate is fixedly mounted on the side of the mounting rod away from the placement plate. The active toothed plate and the passive toothed plate are in a meshing relationship.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) In this utility model, when the collection box is fully loaded and lowered to the lowest position to trigger engagement, the lowering action of the placement plate will be linked by the rack and pinion mechanism to automatically drive the flipping blocking plate back to the closed position, ensuring that the discharge port is always tightly closed during the entire process of replacing the collection box, effectively preventing the fruit from leaking out accidentally. (2) This utility model greatly reduces the impact of the initial falling fruit by raising the empty collection frame to a high position close to the feeding port; and during the collection process, the collection frame is lowered slowly in sync with the height of the fruit pile, always keeping the height of the falling fruit to a minimum, so as to achieve gentle "fruit-to-fruit" collection and minimize damage.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1 to 6 An automatic dragon fruit sorting and size classification device for dragon fruit cultivation includes a frame 1 and a base plate 6. A conveying device 2 is provided on the frame 1, and mounting plates 3 are installed at equal intervals on the conveying device 2. A flipping weighing box 4 is rotatably installed on the mounting plate 3.

[0016] During operation, workers place the harvested dragon fruits in an orderly manner on the tilting weighing box 4 at the starting end of the conveyor device 2. The dragon fruits move with the conveyor device 2. The tilting weighing box 4 has a built-in weighing sensor to accurately measure the weight of each dragon fruit. This part is the same as the principle and specific structure of the DHJS-YP3015F-8 grade tilting bucket weight sorting machine of Zhuhai Dahang Industrial Automation Technology Co., Ltd. in the prior art. Since it is the prior art, it will not be described in detail here.

[0017] The side of the frame 1 is fixedly equipped with discharge ports 5 at equal intervals. Each discharge port 5 is rotatably mounted with a flipping baffle 10. The number of bottom plates 6 is the same as the number of discharge ports 5, and the bottom plates 6 are located directly below the corresponding discharge port 5. The device is set with multiple classification outlets (i.e. multiple discharge ports 5) according to the preset weight range (corresponding to different size grades). Each discharge port 5 corresponds to a specific weight / size grade (e.g., small fruit outlet, medium fruit outlet, large fruit outlet). The flipping baffle 10 is normally in the open state, allowing the dragon fruit to fall normally. When the frame is replaced, the flipping baffle 10 blocks the discharge port 5 to prevent the dragon fruit from falling.

[0018] Multiple base plates 6 are equipped with multi-stage telescopic rods 7, and a placement plate 8 is fixedly installed at the other end of the multi-stage telescopic rods 7. A collection mechanism is provided on the placement plate 8, and a drive mechanism is provided on the discharge port 5.

[0019] Initially, the control system (existing technology) instructs all multi-stage telescopic rods 7 to retract to their longest position, bringing the top of the collection mechanism on the placement plate 8 as close as possible to the bottom of its corresponding discharge port 5. This way, when the flipping baffle 10 opens and the dragon fruit falls into the collection mechanism, the falling distance is very short, the impact force is small, and the fruit is effectively prevented from being damaged by collision. As more dragon fruit of this grade falls into the collection mechanism, the fruit inside the collection mechanism gradually piles up. The control system instructs the multi-stage telescopic rods 7 to slowly and gradually shorten, causing the entire collection mechanism to descend synchronously. In this way, the end of the discharge port 5 always maintains a small relative height difference with the top of the fruit pile inside the collection mechanism. Subsequent falling fruits only need to fall a very short distance to gently land on the fruit pile, achieving "low-distance fruit-to-fruit" protection.

[0020] As a preferred option, the lifting control strategy of the multi-stage telescopic pole 7 has several common methods: it can be based on time estimation: the system estimates the number of fruits falling into each collection device per unit time (or the increase in height) according to the conveying speed and classification frequency, and instructs the telescopic pole to descend a certain distance at preset time intervals; it can also be based on weight control: a gravity sensor is installed under the placement plate 8 to monitor the cumulative total weight of the fruits inside the collection mechanism in real time. When the weight increases to a preset threshold, the system automatically triggers the multi-stage telescopic pole 7 to descend a preset height, so that the top of the collection mechanism is always maintained at a suitable height. Users can choose the control mode according to actual needs. Since this is existing technology, it will not be described in detail here.

[0021] like Figure 3 , Figure 4 As shown, the collection mechanism includes a collection frame 9, a sliding side plate 13 is slidably installed on the side of the collection frame 9 facing the discharge port 5, the sliding side plate 13 is located directly below the discharge port 5, the collection frame 9 has an exposed through groove 18 adapted to the sliding side plate 13, and the placement plate 8 has an alignment groove 20 adapted to the sliding side plate 13.

[0022] The collection frame 9 is a container for holding dragon fruit. The side wall of the collection frame 9 near the discharge port 5 is not fixed, but is equipped with a sliding side plate 13 that can slide up and down. In the initial position (when the collection frame 9 is raised to its highest position), it is exposed through the exposed through groove 18 and the alignment groove 20, so that the edge of the collection frame 9 does not conflict with the discharge port 5, and the collection frame 9 can be raised and lowered normally.

[0023] Preferably, a buffer pad can be installed on the bottom surface of the collection box 9 where it contacts the dragon fruit to reduce the impact force between the dragon fruit accumulated on the discharge port 5 and the collection box 9 when the flipping baffle 10 is initially opened.

[0024] Both the collection frame 9 and the sliding side plate 13 are provided with grip grooves. The grip grooves on the collection frame 9 and the sliding side plate 13 are for the convenience of manual operation by workers (such as replacing the collection frame 9).

[0025] like Figure 3 As shown, a support plate 14 is fixedly installed on the base plate 6, and the support plate 14 can directly abut against the sliding side plate 13.

[0026] The receiving plate 14 is a support structure fixed on the base plate 6. When the multi-stage telescopic rod 7 lifts the placement plate 8 and the collection frame 9 to the highest working position (i.e. the initial position, where the top of the collection frame 9 is closest to the bottom of the discharge port 5), the lower edge of the sliding side plate 13 will abut against the receiving plate 14. This mechanical abutment provides a solid support point for the flipping blocking plate 10, ensuring that it will not move.

[0027] The design of the sliding side plate 13 cleverly solves the interference problem between the collection frame 9 and the fixed discharge port 5 when the collection frame 9 is raised and lowered. When the multi-stage telescopic rod 7 drives the collection frame 9 to descend, the sliding side plate 13 will slide upward relative to the side wall of the collection frame 9 due to the limiting effect of the receiving plate 14 (the collection frame 9 descends, but the sliding side plate 13 does not move). In this way, as the collection frame 9 descends, the sliding side plate 13 will gradually "rise" and always block the opening exposed by the descent of the side wall of the collection frame 9, preventing the dragon fruit in the frame from accidentally rolling out from this side and ensuring the reliability of the collection process.

[0028] like Figure 4 As shown, sliders 16 are fixedly installed on both sides of the sliding side plate 13, and the collection frame 9 has grooves 17 at corresponding positions for the sliders 16 to slide.

[0029] The sliding side plate 13 is embedded in the vertical groove 17 of the side wall of the collection frame 9 by the sliders 16 on both sides, so that the sliding side plate 13 can only perform vertical lifting and lowering movements.

[0030] like Figure 5 As shown, a positioning cavity 19 is provided on the placement plate 8 to fit the collection frame 9.

[0031] The positioning cavity 19 is a recessed area placed on the placement plate 8. Its shape and size are precisely matched with the bottom of the collection box 9. When the worker places the empty collection box 9 on the placement plate 8, he only needs to put it into the positioning cavity 19. The sliding side plate 13 can then be aligned with the exposed through groove 18 and the alignment groove 20, and the sliding side plate 13 can smoothly descend.

[0032] like Figure 6As shown, the drive mechanism includes a mounting shaft 11 and a mounting rod 15. The mounting shaft 11 is fixedly mounted on the drive shaft of the flipping baffle plate 10. The mounting shaft 11 passes through the discharge port 5 and is fixedly mounted with a passive toothed plate 12. The mounting rod 15 is fixedly mounted on the placement plate 8. The side of the mounting rod 15 away from the placement plate 8 is fixedly mounted with a drive toothed plate 21. The drive toothed plate 21 and the passive toothed plate 12 are in a meshing relationship.

[0033] The drive mechanism is triggered at the lower end of the placement plate 8. When the collection box 9 is lowered to the lowest position (end) by the multi-stage telescopic rod 7 along with the placement plate 8 because it is filled with dragon fruit, the mounting rod 15 fixed on the placement plate 8 and the active toothed plate 21 (rack) at its top also lower to the low position. At this time, the active toothed plate 21 and the passive toothed plate 12 fixed on the rotating shaft mounting shaft 11 of the flipping baffle 10 engage. Subsequently, when it is necessary to replace the empty box, the control system commands the multi-stage telescopic rod 7 to descend, and the active toothed plate 21 (rack) descends accordingly. Through engagement, the passive toothed plate 12 and the mounting shaft 11 are driven to rotate, thereby causing the flipping baffle 10 to block the discharge port 5 and prevent the dragon fruit from falling accidentally during the replacement of the collection box 9.

[0034] After the replacement is completed, the multi-stage telescopic rod 7 raises the placement plate 8 to the working height (i.e., the initial position of the empty frame). The active toothed plate 21 moves upward and disengages from the passive toothed plate 12. In the initial stage of this lifting process, the meshing action drives the flipping baffle plate 10 back to the open position and makes the flipping baffle plate 10 fit against the surface of the discharge port 5. At this time, the dragon fruit can fall smoothly through the discharge port 5. During the subsequent descent of the collection frame 9 (not at the end), the active toothed plate 21 and the passive toothed plate 12 do not contact each other until the next meshing (at the end).

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
