Description

Technical Field

[0001] This utility model belongs to the technical field of asparagus sorting equipment, specifically relating to an asparagus support lifting device. Background Technology

[0002] Most existing asparagus sorting machines use flat conveyor belts for sorting. The sorting action actuator physically guides the asparagus to the corresponding collection box or conveyor belt based on the decision result. The sorting action is implemented in the following ways: (1) Mechanical lever / push plate: In lower speeds or specific designs, a robotic arm or movable baffle may be used to push the asparagus into different channels. (2) Guide trough: A guide device that can quickly switch directions is set at the sorting point to guide the asparagus into different paths.

[0003] Asparagus has a wide length range, and its commercial sorting needs to accommodate common lengths of 15cm to 28cm (some varieties can reach over 30cm), while the natural length variation at harvest is even greater (10cm-35cm). Using a flat conveyor belt for sorting presents significant challenges because the asparagus's posture is easily uncontrollable: asparagus tends to roll and pile up on the conveyor belt, making it impossible to maintain a single parallel stalk; very short asparagus is prone to getting stuck in machine gaps, and extra-long asparagus requires increased spacing between workstations, etc.

[0004] To address the technical problems in sorting asparagus using a flat conveyor belt, those skilled in the art have been developing a method to sort asparagus by flipping the asparagus tray (flipping the asparagus tray from horizontal to inclined). However, resetting the asparagus tray after flipping is a technical challenge in the research and development process. Utility Model Content

[0005] This invention addresses the problem of resetting asparagus support frames after flipping in the prior art by providing an asparagus support frame lifting device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an asparagus support lifting device, wherein the asparagus support is installed on a circulating conveyor chain; the circulating conveyor chain includes a chain shaft and two parallel chains, each chain having multiple support frames installed on it, and the end of the asparagus support along its length is hinged to the end of the support frame away from the chain; sprockets are installed at both ends of the chain shaft, the chain cooperates with the sprockets, and a lifter is installed on the chain shaft; the lifter includes one or more C-shaped bend structures; during the operation of the circulating conveyor chain, the lifter enables the asparagus support to rotate upward around the end of the support frame to achieve lifting.

[0007] Preferably, the lifter includes two centrally symmetrical C-shaped bends, and the lifter is in the form of an inverted S-shape; the middle position of the lifter is a ring-shaped part, which is fixedly or detachably connected to the chain shaft.

[0008] Preferably, the spacing between adjacent support frames on the chain is equal to the distance the chain moves when the chain axis rotates 180 degrees.

[0009] Preferably, the asparagus support includes a slider, a connecting part, and a tray; the number of trays is one or more; the tray has a bent portion; the connecting part is hinged to the end of the support frame away from the chain, and the connecting part is located on the side of the asparagus support away from the bent portion of the tray; the slider is installed at the end of the asparagus support along its length, and the horizontal projection of the slider partially exceeds the horizontal projection of the tray.

[0010] Preferably, the asparagus support lifting device is installed inside the asparagus sorting machine, which includes a frame and slide rails distributed along the length of the frame; after the asparagus support is lifted by rotating upward around the end of the support frame away from the support frame, the lower surface of the sliding member is slidably connected to the upper surface of the slide rail.

[0011] Preferably, the circulating conveyor chain further includes a second chain shaft, with the first chain shaft and the second chain shaft located at opposite ends of the length of the asparagus sorting machine.

[0012] Preferably, the C-shaped bend structure of the lifting device is a C-shaped spring steel sheet.

[0013] Preferably, the upper part of the chain runs from chain axis one to chain axis two.

[0014] Preferably, during the operation of the circulating conveyor chain, the C-shaped bend structure of the lifter can contact the lower end of the bent portion of the pallet.

During the operation of the circulating conveyor chain, the lifting device can make the asparagus support rotate upward around the end of the support frame to achieve lifting.

[0018] (2) The lifting device raises the asparagus bracket. As the asparagus bracket moves with the chain, the sliding part can fall onto the slide rail after the asparagus bracket descends. Then the sliding part and the slide rail are slidably connected, and the asparagus bracket changes from an inclined state to a horizontal state.

[0019] (3) The lifting device includes one or more C-shaped bend structures. When the lifting device is in reverse S-shape, the distance between adjacent support frames on the chain is equal to the distance the chain moves when the chain shaft rotates 180 degrees.

[0036] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0038] Example 1

[0039] The following is combined Figures 1-7 The asparagus support lifting device in Example 1 is further described below, such as... Figure 1 and Figure 2 As shown, an asparagus support lifting device is provided, wherein the asparagus support 2 is installed on a circulating conveyor chain; the circulating conveyor chain includes a chain shaft 4 and two parallel chains 5, and multiple support frames 6 are installed on each chain 5 respectively, and the ends of the asparagus support 2 in the length direction are hinged to the ends of the support frames 6 away from the chains 5.

[0040] like Figure 2 and Figure 3 As shown, sprockets are installed at both ends of the chain shaft 4, the chain 5 cooperates with the sprockets, and a lifter 3 is installed on the chain shaft 4; the lifter 3 includes two C-shaped bend structures.

[0041] like Figure 2 As shown, during the operation of the circulating conveyor chain, the lifter 3 can make the asparagus bracket 2 rotate upward around the end of the support frame 6 to achieve lifting.

[0042] like Figure 3 As shown, the lifter 3 includes two centrally symmetrical C-shaped bends, and the lifter 3 is in the shape of an inverted S; the middle position of the lifter 3 is a ring-shaped part, which is fixedly or detachably connected to the chain shaft 4.

[0043] The distance between adjacent support frames 6 on chain 5 is equal to the distance chain 5 moves when chain shaft 4 rotates 180 degrees.

[0044] like Figure 4 and Figure 5 As shown, the asparagus support 2 includes a slider 21, a connecting part 22, and a support plate 23; the number of support plates 23 is one or more; the support plate 23 has a bent part; the connecting part 22 is hinged to the end of the support frame 6 away from the chain 5, and the connecting part 22 is located on the side of the asparagus support 2 away from the bent part of the support plate 23; the slider 21 is installed at the end of the asparagus support 2 along its length, and the horizontal projection of the slider 21 partially exceeds the horizontal projection of the support plate 23.

[0045] like Figure 2 and Figure 6 As shown, the asparagus support lifting device is installed inside the asparagus sorting machine 1. The asparagus sorting machine 1 includes a frame and slide rails 7 distributed along the length of the frame. After the asparagus support 2 is lifted by rotating upward around the end of the support frame 6, the lower surface of the sliding member 21 is slidably connected to the upper surface of the slide rail 7.

[0046] The circulating conveyor chain also includes chain shaft 2. Chain shaft 4 and chain shaft 2 are located at both ends of the length direction of the asparagus sorting machine 1.

[0047] The C-shaped bend structure of the lifting device 3 is a C-shaped spring steel sheet.

[0048] The upper part of chain 5 runs from chain shaft 4 to chain shaft 2.

[0049] like Figure 2 As shown, during the operation of the circulating conveyor chain, the C-shaped bend structure of the lifter 3 can contact the lower end of the bend of the pallet 23.

[0050] Example 2

[0051] The difference between this embodiment and embodiment 1 is that the lifting device 3 includes three C-shaped bends, and the included angle between adjacent C-shaped bends is 120 degrees; the distance between adjacent support frames 6 on the chain 5 is equal to the distance the chain 5 moves when the chain shaft 4 rotates 120 degrees.

[0052] Example 3

[0053] The difference between this embodiment and Embodiment 1 is: Figure 8 and Figure 9 As shown, the lifting device 3 includes a C-shaped bend structure, and the distance between adjacent support frames 6 on the chain 5 is equal to the distance the chain 5 moves when the chain shaft 4 rotates 360 degrees.

[0054] Working principle of the asparagus support lifting device in Examples 1 to 3:

[0055] like Figure 2 and Figure 6 As shown, during the operation of the circulating conveyor chain, the lifter 3 enables the asparagus bracket 2 to rotate upwards around the end of the support frame 6, thereby lifting it. Figure 8 As shown, during the operation of the circulating conveyor chain, when the support frame 6 is horizontal, the asparagus bracket 2 hangs vertically downwards (under its own weight) and does not contact the lifter 3; as the chain 5 continues to rotate, as... Figure 9 As shown, the C-shaped bend of the lifter 3 contacts the lower end of the bend in the pallet 23, at which point the bend in the pallet 23 and the contact area of ​​the lifter 3 have the same curve movement speed; as the chain 5 continues to run, as Figure 2As shown, although the C-shaped bend structure of the lifter 3 is still in contact with the lower end of the bend of the pallet 23, they will no longer be able to keep in sync in the next moment, because the lifter 3 continues to rotate around the axis of the chain shaft 4, while the bend of the pallet 23 can only rotate upward around the end of the support frame 6 under the action of inertia.

[0056] As the lifter 3 raises the asparagus bracket 2, the asparagus bracket 2 also moves with the chain 5, so after the asparagus bracket 2 descends, the sliding member 21 can fall onto the slide rail 7; then the sliding member 21 and the slide rail 7 are slidably connected, and the asparagus bracket 2 changes from an inclined state to a horizontal state.

[0057] The asparagus sorting machine 1 sorts asparagus by controlling the rotation of the asparagus tray 2 on the side away from the chain shaft 4. Technical means to achieve the rotation of the asparagus tray 2 include: the slide rail 7 is a movable or rotatable section; when the sliding member 21 passes through the movable or rotatable section, it no longer maintains a sliding connection with the slide rail 7 (for example, the slide rail 7 is a movable section that can move outwards from the frame; when the movable section moves, the slide rail 7 no longer supports the sliding member 21), and subsequently, the asparagus tray 2 rotates around the end of the support frame 6 (e.g., ...). Figure 7 As shown), asparagus on asparagus tray 2 falls into the sorting box below.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
