[0002] Harvesting broad bean seedlings infested with aphid midge larvae is a crucial step in aphid midge propagation and inoculation. Currently, this process relies on manual scissoring, typically producing 30-50 trays per hour, resulting in low efficiency. To improve operational efficiency, a machine suitable for harvesting aphid-infested broad bean seedlings grown in seedling trays is needed.
[0003] Meanwhile, the existing cutting device has large vibrations, which can easily shake off the aphid-eating gall midge larvae on the broad bean seedlings during harvesting, and is not suitable for harvesting broad bean seedlings with aphids. Meanwhile, the existing device is large in size and is not easy to pass between the culture racks.
[0004] That is, a harvester for broad bean seedlings with aphids is needed, which has a simple and small structure and can pass between indoor culture racks; and has small cutting vibration and will not shake off the aphid-eating gall midge larvae attached to the broad bean seedlings. Summary of the Invention
[0005] In view of this, the purpose of the utility model is to provide a reciprocating cutting slope harvester for aphid-carrying broad bean seedlings, which can pass between indoor culture racks with a simple and small structure; the cutting vibration is small and the aphid-eating gall midge larvae attached to the broad bean seedlings will not be shaken away; and the shortcomings of the existing technology can be overcome.
[0006] The purpose of this utility model is achieved through the following technical solutions:
[0007] The utility model discloses a reciprocating cutting type inclined harvester for broad bean seedlings with aphids. The harvester comprises an inclined frame, a conveying mechanism is arranged on the frame, and a harvesting mechanism is arranged on the frame. A moving channel for a seedling tray is provided between the harvesting mechanism and the conveying mechanism. The harvesting mechanism cuts and collects the broad bean seedlings with aphids on the seedling tray passing through.
[0008] The above-mentioned harvesting agencies include:
[0009] A collecting box is fixed on the frame through a positioning bracket, and a collecting port for aphid-carrying broad bean seedlings is provided on one side of the collecting box. The moving channel is located between the collecting box and the conveying mechanism.
[0010] The cutting device is a reciprocating cutter, and the cutting device is fixed on the collection box on one side of the collection port.
[0011] The cutter of the reciprocating cutter is provided with serrations on both sides.
[0012] As mentioned above, a movable opening and closing door is provided on one side of the collection box opposite to the collection port.
[0013] The conveying mechanism is composed of a conveying belt, a roller, a support plate, a tensioning device and a motor drive system.
[0014] As mentioned above, the upper surface of the conveyor belt is provided with a blocking grid of the seedling tray.
[0015] As mentioned above, a support leg is provided at the upper end of the frame, and casters and a locking assembly of the casters are provided at the support leg and the lower end of the frame.

[0021] 3. The reciprocating cutter has serrations on both sides of the cutter. Because the cutter is a wearing part, considering the later maintenance and use costs, a double blade is used. If one side is worn, the other side can be switched for use.
[0022] 4. A movable switch door is provided on one side of the collection box opposite to the collection port, so that when enough broad bean seedlings are harvested, the movable switch door can be opened and the broad bean seedlings can be transferred through the collection frame or the like.
[0023] 5. There are seedling tray blocks on the upper surface of the conveyor belt, which can prevent the seedling tray from moving during the transmission process.
[0024] 6. Support legs are provided at the upper end of the rack, and casters and caster locking assemblies are provided at the support legs and the lower end of the rack. This makes it easier to move the device through the casters, and easier to position the device during use through the caster locking assemblies.
[0025] 7. Through the angle adjustment device, the user can adjust the inclination of the device according to his or her height requirements.
[0026] Other advantages, objectives, and features of the present invention will be described in detail in the following description and, to some extent, will be apparent to those skilled in the art upon examination and study of the following or may be learned from practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0031] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention and are not intended to limit the scope of protection of the present invention.
[0032] like Figure 1-Figure 2 As shown, the utility model discloses a reciprocating cutting inclined harvester for aphid-carrying broad bean seedlings, which includes an inclined frame 1, a conveying mechanism 2 is provided on the frame 1, a harvesting mechanism 3 is provided on the frame 1, and a moving channel 4 for the seedling tray is provided between the harvesting mechanism 3 and the conveying mechanism 2. The harvesting mechanism 3 cuts and collects the aphid-carrying broad bean seedlings on the seedling tray passing through. The device places the seedling tray on the conveying mechanism 2, transfers it to the harvesting mechanism 3, and then harvests. The device has a simple structure and can be easily passed between indoor culture racks.
[0033] Furthermore, the harvesting mechanism 3 includes a collecting box 3-1 and a cutting device 3-3. Specifically,
[0034] The collecting box 3-1 is fixed on the frame 1 by a positioning bracket. A collecting port 3-2 for aphid-carrying broad bean seedlings is provided on one side of the collecting box 3-1. The moving channel 4 is located between the collecting box 3-1 and the conveying mechanism 2. The cutting device 3-3 and the cutting device 3-3 are reciprocating cutters. The cutting device 3-3 is fixed on the collecting box 3-1 on the side of the collecting port 3-2. With such a structure, the aphid-carrying broad bean seedlings can be cut by the reciprocating cutter. At the same time, the reciprocating cutter used cuts the broad bean seedling stems by moving the double blades horizontally. The double blades realize lateral support cutting of the broad bean seedlings during cutting, which can significantly reduce the lateral impact vibration of the broad bean seedlings when cutting. The inclined frame 1 and the conveying mechanism 2 enable the broad bean seedlings to fall into the collecting box 3-1 by their own gravity after being cut, without the need for an additional guiding and pushing device, thereby avoiding the impact vibration caused by mechanical collision, which can effectively reduce the vibration of the aphid-carrying gall midge larvae.
[0035] The reciprocating cutter blade features serrations on both sides. The key structural parameters of a reciprocating cutter include blade width, blade height, and front axle width. Different blade parameters result in different cutting performance. To improve cutting efficiency and reduce cutting vibration, the cutter was simulated and analyzed using Adams. The optimal structural parameter combination was determined to be: a blade width of 90 mm, a blade height of 52.08 mm, and a front axle width of 14.75 mm. This achieved a cutting efficiency of 96%. Because cutters are consumable parts, a comparable finished blade was selected for use in harvesters, taking maintenance and operating costs into consideration. The finished blade has a 90 mm blade width, a 45 mm blade height, and a front axle width of 16 mm. The cutter features a dual blade, which can be swapped if one side wears out. It is driven by a 24V DC motor with a rated operating power of 50W. It is compatible with a 24V DC regulated power supply that converts a single-phase 220V power supply to 24V DC.
[0036] Furthermore, a movable switch door 3-4 is provided on one side of the collecting box 3-1 opposite to the collecting port 3-2, so that when enough broad bean seedlings are harvested, the movable switch door 3-4 can be opened and the broad bean seedlings can be transferred through the collecting frame or the like.
[0037] Furthermore, the conveying mechanism 2 is composed of a conveying belt, a roller, a support plate, a tensioning device and a motor drive system.
[0038] Furthermore, a blocking grid 5 for the seedling tray is distributed on the upper surface of the conveyor belt. The blocking grid 5 is integrally formed with the conveyor belt or fixed by super glue at a later stage. The blocking grid 5 can prevent the seedling tray from moving during the conveying process.
[0039] Furthermore, a support foot 6 is provided at the upper end of the frame 1, and casters and caster locking assemblies are provided at both the support foot 6 and the lower end of the frame 1. This facilitates movement of the device through the casters, and facilitates positioning during use through the caster locking assemblies. At the same time, the support foot 6 is hinged to the frame 1, and an angle adjustment device for the support foot 6 is provided between the support foot 6 and the frame 1. The angle adjustment device includes an arc-shaped guide rail 7 provided on the frame 1, a guide rod 8 that cooperates with the arc-shaped guide rail 7, and a positioning device provided on the support foot 6; the positioning device includes a plurality of locking holes distributed on the arc-shaped guide rail 7, and a locking pin that cooperates with the locking holes provided on the support foot 6. In this way, through the angle adjustment device, the user can adjust the inclination of the device according to their height requirements.
[0040] When in use, turn on the driving motor of the conveying mechanism 2, adjust the conveying speed, turn on the switch of the cutting device 3-3 at the same time, then put the seedling tray on the conveyor belt, and use the blocking grid 5 to prevent the displacement of the seedling tray. When the seedling tray passes through the moving channel 4 between the collecting box 3-1 and the conveyor belt, the broad bean seedlings are cut by the cutting device 3-3 on the side of the collecting port 3-2 of the collecting box 3-1. The cut broad bean seedlings automatically fall into the collecting box 3-1 in an inclined state, completing the harvesting, and the harvested seedling tray continues to move downward, and subsequent staff will transfer it.
[0041] The above description is only a preferred embodiment of the present invention and does not constitute any form of confidentiality restriction on the present invention. Any simple modification, equivalent change and modification of the above embodiment made based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
