Description

Technical Field

[0001] This utility model relates to the technical field of peanut vine separators, specifically a continuous peanut vine separator. Background Technology

[0002] Traditional peanut harvesting is a time-consuming and physically demanding task. For large-scale peanut harvesting, peanut combine harvesters are generally used. However, due to their large size, peanut combine harvesters are only suitable for use in flat areas and are not suitable for small-scale planting or uneven land. For small-scale peanut planting or planting on uneven land, manual harvesting is still the most common method. This method is inefficient, especially in separating the peanuts from the vines, which requires a lot of time.

[0003] Based on this, the present invention aims to provide a fruit seedling separator that can adapt to small-scale or uneven planting environments. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a continuous peanut vine separator. This separator is small in size and can be directly installed and fixed using a frame, eliminating the need to enter the field. In small-scale or uneven planting environments, peanut vines can be collected and harvested directly using the continuous peanut vine separator. It utilizes an upper belt conveyor and a lower belt conveyor to achieve the dual functions of conveying and pressing peanut vines. When the peanut vines are conveyed to the stationary rake, the moving rake teeth of the moving rake group insert into the root of the stationary rake teeth under the drive of the rotating shaft, realizing the vine-grabbing action. At this time, the vine-pressing conveyor unit is still in motion, forming a vine-pulling action, thus achieving the separation of peanut vines and peanut vines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A continuous peanut vine separator includes a frame, on which a set of stationary rakes is fixedly installed. A rotating shaft is provided on the frame on the side opposite to the tips of the stationary rakes, and a set of movable rakes that matches the stationary rakes is provided on the rotating shaft. The frame is provided with a seedling pressing and conveying unit on the side away from the tip of the stationary rake teeth. The seedling pressing and conveying unit includes a lower belt conveyor. The upper surface of the conveyor belt of the lower belt conveyor is flush with the stationary rake. An upper belt conveyor for pressing seedlings is provided above the lower belt conveyor. The upper belt conveyor and the lower belt conveyor move in opposite directions at the same speed. The frame is equipped with drive shafts, drive motors for the upper belt conveyor and the lower belt conveyor.

[0006] In this utility model, the upper belt conveyor includes an upper pressing frame, with rollers installed at the four corners of the upper pressing frame, and a tensioning structure provided between the upper and lower rollers on one side of the upper pressing frame. A connecting seat is fixed on the upper pressing frame, and the connecting seat is connected to the pressing roller assembly through an elastic structure. The pressing roller of the pressing roller assembly is located below the upper pressing frame. The conveyor belt of the upper belt conveyor is wrapped around four rollers, a tensioning structure, and a pressing roller.

[0007] In this utility model, the pressing roller assembly includes a pressing roller fixing seat, which is an inverted U-shaped groove. The bottom of both sides of the U-shaped groove is provided with multiple corresponding slots. The mounting shafts at both ends of the multiple pressing rollers are respectively set in the corresponding slots. A fixing plate is provided on the outside of the U-shaped groove to prevent the pressing rollers from falling off.

[0008] In this invention, the multiple pressing rollers are arranged closely in sequence; the multiple pressing rollers are located outside the stationary toothed rake, and the combined length of the multiple pressing rollers is not less than the width of the stationary toothed rake.

[0009] In this invention, both ends of the lower belt conveyor are located outside the upper belt conveyor; the four rollers of the upper belt conveyor are distributed at the four corners of the inverted trapezoid.

[0010] In this utility model, the upper surfaces of both ends of the U-shaped groove are provided with side plates, and the side plates are provided with guide shafts; the two ends of the connecting seat are provided with guide plates opposite to the side plates, and the guide plates are provided with guide grooves that match the guide shafts.

[0011] In this utility model, the elastic structure includes multiple sets of compression spring structures. Each set of compression spring structures includes spring seats respectively disposed on the top of the pressing roller fixing seat and the connecting seat, and the two spring seats are connected by compression springs.

[0012] In this utility model, the tensioning structure includes a U-shaped tensioning roller seat frame, which includes two opposing side plates and a bottom plate. Each side plate has a corresponding groove extending downwards from the top. A tensioning roller is installed in the groove, and both ends of the tensioning roller are mounted on two tensioning roller seats. The two tensioning roller seats are located on the outside of the U-shaped tensioning roller seat frame. The two tensioning roller seats are fitted with integrally formed pull strips attached to the side plates. A sliding pin is fixedly installed on the pull strip away from the end of the tensioning roller, and the sliding pin is inserted into the groove. Fixed pins are provided on the inner walls of the top of each side plate, and the fixed pins are connected to the sliding pins by a tension spring.

[0013] In this invention, a collection tray is provided below the stationary rake on the frame, and peanuts that fall off the peanut vines are collected by the collection tray.

[0014] In this invention, the moving toothed rake assembly is equipped with a safety guard, which serves two purposes: firstly, to protect personnel safety, and secondly, to prevent peanuts from flying away during the peanut harvesting process.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes an upper belt conveyor and a lower belt conveyor to achieve the dual functions of conveying and pressing peanut vines. When the peanut vines are conveyed to the stationary toothed rake, the rake teeth of the moving toothed rake group are inserted from the root of the rake teeth of the stationary toothed rake under the drive of the rotating shaft, realizing the fruit-grabbing action. At this time, the pressing and conveying unit is still moving, forming the fruit-pulling action, realizing the separation of peanut fruit and vine.

[0016] 2. In this utility model, the seedling pressing roller assembly of the upper belt conveyor is connected to the upper seedling pressing frame through an elastic structure. When the peanut seedlings are conveyed to the upper belt conveyor, the elastic structure design allows the belt conveyor to adjust the distance between the upper belt conveyor and the lower belt conveyor according to the thickness of the peanut seedlings, preventing the peanut seedlings from being directly crushed.

[0017] 3. This utility model has a tensioning structure between the upper and lower rollers on one side of the upper pressing frame. The tensioning structure uses the sliding groove of the U-shaped tensioning roller seat and the tension spring to adjust the position of the tensioning roller seat, thereby realizing the feeding and unfeeding of the upper belt conveyor and controlling the gap between the upper and lower belt conveyors.
