Description

Technical Field

[0001] This invention relates to the field of harvesting equipment technology, specifically a leafy vegetable orderly harvester. Background Technology

[0002] CN118340021A discloses a vegetable orderly harvesting and packing device and method, and a harvester, including a pulling device, a cutting device, and an orderly conveying device. It also includes a vegetable guide device for containing and rotating and tilting vegetables, a collection frame for collecting vegetables, and a control device. The control device is connected to the pulling device, the cutting device, the orderly conveying device, and the vegetable guide device. The vegetable guide device is located at the discharge port of the orderly conveying device. The vegetables are vertically conveyed into the vegetable guide device. Under the rotation of the vegetable guide device, the vegetables are separated from the vegetable guide device and horizontally and orderly laid into the collection frame. This vegetable orderly harvesting and packing device has the advantage of being able to achieve orderly packing of densely planted leafy vegetables.

[0003] However, when the above-mentioned orderly vegetable harvesting and packing device is in use, the side conveyor belt transports the vegetable leaves, which is efficient for transporting the leaves on both sides. However, the vegetables in the middle are prone to getting stuck in the transport channel. As the harvesting work progresses, the vegetables will accumulate in the transport channel, affecting the vegetable harvesting efficiency. Optimization and improvement are needed to solve this technical problem. Summary of the Invention

[0004] The purpose of this invention is to provide an orderly harvester for leafy vegetables to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An orderly harvester for leafy vegetables includes: The vehicle body, on which a frame is installed; A harvesting assembly, comprising a cutting mechanism disposed at the end of the frame and a turntable mechanism disposed on the side wall of the frame, wherein the turntable assembly is used to draw the vegetable leaves toward the cutting mechanism so that the cutting mechanism cuts the vegetable leaves; The harvesting assembly includes a bottom conveying mechanism disposed on the bottom wall of the frame, a feeding mechanism disposed on the frame and located on both sides of the bottom conveying mechanism, and a collection box disposed at the end of the frame. The feeding mechanism includes a side conveying mechanism disposed on the frame, a control slide rail disposed on the frame, a squeezing control component disposed on the control slide rail and connected to the side conveying mechanism, a feeding tube disposed on the side conveying mechanism and connected to the squeezing control mechanism, and a support component disposed on the squeezing control mechanism. The side conveying mechanism drives the squeezing control component to move along the control slide rail. When the squeezing control component moves to the cutting mechanism, the squeezing control component straightens and unfolds the feeding tube to cooperate with the bottom conveying mechanism to send the vegetable leaves into the collection box. When the squeezing control component moves to the collection box, the feeding tube drops.

[0006] Preferably, the frame is provided with a transport groove, the bottom wall of the transport groove is provided with a transport installation groove, the vehicle body is provided with a height adjustment telescopic rod, and the frame is mounted on the height adjustment telescopic rod.

[0007] Preferably, the cutting mechanism includes a cutter mounted on the frame and a cutting motor mounted on the cutter, and the dial mechanism includes a folding bracket mounted on the frame, a rotating frame mounted on the folding bracket, a feeding lever mounted on the rotating frame, and a dial motor mounted on the folding bracket and connected to the rotating frame.

[0008] Preferably, the bottom conveying mechanism includes a bottom conveyor belt disposed within the transport installation trough and a bottom transport motor disposed on the wall of the transport installation trough and connected to the bottom conveyor belt.

[0009] Preferably, the side conveying mechanism includes a side conveyor belt disposed on the wall of the conveying trough, a side transport motor disposed on the frame and connected to the side conveyor belt, and a clamping groove formed on the side conveyor belt.

[0012] Preferably, the push tube includes a tube body inserted into the side conveyor belt and communicating with the airbag, a reinforcing rib disposed in the tube body, and a weight block disposed at the end of the tube body. The reinforcing rib is not disposed at the root where the tube body connects to the side conveyor belt.

[0013] Preferably, the support component includes a movable arc support rod disposed on the control base rod and passing through the clamping groove, and a fixed arc support rod disposed on the side conveyor belt.

[0014] Preferably, the side conveyor motor drives the side conveyor belt to rotate, thereby causing the control base rod to move along the control slide rail. When the control base rod moves from the descending venting section to the ascending extrusion section, the control base rod pushes the push block to move upward along the extrusion cylinder, extruding the airbag and inflating the tube, causing the tube to straighten and unfold. At the same time, the movable arc support rod moves upward to cooperate with the fixed arc support rod to fix the root of the tube. When the control base rod moves from the ascending extrusion section to the descending venting section, the reset spring pushes the push block downward, causing the airbag to draw air from the tube. The root of the tube bends and retracts into the gap between the conveying groove and the side conveyor belt.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention achieves orderly transportation from the bottom and sides by setting up a bottom conveyor belt and a side conveyor belt. With the setting of a foldable tube, the tube unfolds from the folded state when it runs above the bottom conveyor belt, and works with the bottom conveyor belt to achieve coordinated transportation from the top and bottom. It also moves the vegetable leaves in the middle synchronously, achieving all-round high-efficiency transportation, solving the problem of vegetables in the middle congesting in the transportation channel, and improving the transportation efficiency of vegetable leaves.

The side transport motor 17 drives the side conveyor belt 16 to rotate, thereby driving the control base rod 19 to move along the control slide rail 4. When the control base rod 19 moves from the descending venting section 41 to the ascending extrusion section 42, the control base rod 19 pushes the push block 24 to move upward along the extrusion cylinder 26, extruding the air bladder 27 and inflating the tube 29. The pressure causes the tube 29 to straighten and unfold. At the same time, the movable arc support rod 32 moves upward to cooperate with the fixed arc support rod 33 to fix the root of the tube 29. The bottom conveyor belt 14 sends the vegetable leaves into the collection box 3. When the control base rod 19 moves from the rising extrusion section 42 to the falling deflating section 41, the reset spring 28 pushes the push block 24 downward, causing the air bag 27 to draw air from the tube 29. The root of the tube 29 bends and closes into the gap between the conveying trough 5 and the side conveyor belt 16. The speed of transporting the vegetable leaves is adjusted by controlling the bottom conveyor motor 15 and the side conveyor motor 17.
