Technical Field

[0001] This utility model relates to the field of lifting device technology, and in particular to the lifting device for a sugar beet harvester. Background Technology

[0002] A sugar beet harvester is an agricultural machine specifically designed for harvesting sugar beets. It can complete a series of operations during the harvesting process, including removing stems and leaves, digging up the tubers, cleaning and conveying, and picking up and loading. The main function of the harvester's lifting device is to pull the sugar beet tubers out of the soil and transport them to the subsequent processing device. It is usually used in conjunction with the digging device to ensure that the sugar beets can be smoothly removed from the soil and collected. The application of sugar beet harvesters is of great significance for improving the mechanization level and production efficiency of sugar beet cultivation.

[0003] Meanwhile, existing pulling devices typically use a digging structure to excavate and collect the beet green tops and beet tubers together, which cannot accurately separate the beet green tops and tubers. This results in additional processing of the green tops during subsequent cleaning work, increasing the difficulty and labor intensity of subsequent cleaning and reducing the overall harvesting efficiency. Summary of the Invention

[0004] To overcome the problem that existing lifting devices cannot accurately separate the green top and tuber of sugar beets, which leads to additional processing of the green top during subsequent cleaning, increasing the difficulty and labor intensity of subsequent cleaning and reducing the overall harvesting efficiency, this utility model provides a lifting device for a sugar beet harvester.

[0005] The technical solution is as follows: The lifting device of the sugar beet harvester includes a harvester and a fixed frame; the fixed frame is provided at the outer end of the harvester and is welded and fixed to the harvester; it also includes a movable plate, a drive motor, a baffle, a connecting frame, a tilting frame, a guardrail, and a collection box; a rotating rod is installed inside the fixed frame, and a movable plate is fitted on the outer wall of the rotating rod. A rotary motor is installed at one end of the rotating rod on the outer wall of the fixed frame. A rotating groove is opened inside the movable plate, and a drive rod is fixed inside the rotating groove. Several sets of blades are welded circumferentially to the outer end of the drive rod. A drive motor is fixed at one end of the drive rod on the outer wall of the movable frame. A baffle is installed on one side of the several sets of blades at the lower end of the movable frame. A connecting frame is provided at the lower end of the fixed frame, and a connecting rod is installed inside the connecting frame. A tilting frame is fitted on the outer wall of the connecting rod on the inner side of the connecting frame. A power motor is installed at one end of the connecting rod on the outer wall of the connecting frame.

[0006] Furthermore, connecting blocks are symmetrically welded to the upper end of the baffle, and fixing bolts are provided inside the connecting blocks. Multiple sets of connecting holes for accommodating fixing bolts are opened on the outer wall of the movable plate, and the baffle is threadedly limited to the movable plate by the fixing bolts.

[0007] Furthermore, two sets of fixing plates are installed on the outer wall of the connecting frame. The two sets of fixing plates are equipped with limit screws inside, and the two sets of fixing plates are fixedly connected to the connecting frame through the limit screws.

[0008] Furthermore, a power motor is installed at one end of the connecting rod on the outer wall of the connecting frame, and the tilting frame is rotated along the inside of the connecting frame via the connecting rod.

[0009] Furthermore, multiple sets of guardrails are installed on the inner wall of the connecting frame, and these guardrails are welded to the connecting frame for positioning.

[0010] Furthermore, a positioning plate is welded to the lower end of the harvester, and two sets of tracks are provided on the outer wall of the positioning plate. The harvester is fixed to the two sets of tracks through the positioning plate.

[0011] Furthermore, a collection box is provided at the lower end of the positioning plate. One end of the collection box is located on one side of the tilting frame and has an inlet. The collection box is welded and fixed to the positioning plate.

The sealing plate is threadedly fixed to the collection box by the screws, and a guide plate is welded to one end of the collection box below the sealing plate.

[0013] The beneficial effects are: This utility model achieves precise adjustment of the blade cutting position according to the actual height of the beet leaves by using a rotary motor, avoiding excessive or insufficient cutting, flexibly responding to different cutting changes, effectively removing the green top of the beet, ensuring the best cutting effect in different fields and growing conditions, reducing the waste of beet root raw materials, and improving the integrity of beet harvest.

[0014] By using baffles to block the green tops of beets during the cutting process, the beet roots are prevented from being collected together during the subsequent harvesting, thus improving the purity of the beet roots. Furthermore, using baffles to initially separate the green tops reduces the need for subsequent cleaning work and speeds up the harvesting process. Attached Figure Description

[0022] like Figures 1-5 As shown, the lifting device of the beet harvester 1 includes a harvester 1 and a fixed frame 2; the fixed frame 2 is provided at the outer end of the harvester 1, and the fixed frame 2 is welded and fixed to the harvester 1; it also includes a movable plate 3, a drive motor 6, a baffle 7, a connecting frame 11, a tilting frame 12, a guardrail 13 and a collection box 18; a rotating rod is installed inside the fixed frame 2, and the movable plate 3 is fitted on the outer wall of the rotating rod. A rotating motor 10 is installed at one end of the rotating rod on the outer wall of the fixed frame 2. A rotating groove is opened inside the movable plate 3, and a drive rod 4 is fixed inside the rotating groove. Several sets of blades 5 are welded circumferentially to the outer end of the drive rod 4. A drive motor 6 is fixed at one end of the drive rod 4 on the outer wall of the movable frame. A baffle 7 is installed at the lower end of the movable frame on one side of the several sets of blades 5. A connecting frame 11 is provided at the lower end of the fixed frame 2. A connecting rod 16 is installed inside the connecting frame 11. A tilting frame 12 is fitted on the outer wall of the connecting rod 16 on the inner side of the connecting frame 11. A power motor 14 is installed at one end of the connecting rod 16 on the outer wall of the connecting frame 11.

[0023] Please see Figures 2-4 A connecting block 8 is symmetrically welded to the upper end of the baffle 7. The connecting block 8 is provided with a fixing bolt 9 inside. The outer wall of the movable plate 3 has multiple sets of connecting holes to accommodate the fixing bolt 9. The baffle 7 is threadedly limited to the movable plate 3 by the fixing bolt 9. Two sets of fixing plates 15 are installed on the outer wall of the connecting frame 11. The two sets of fixing plates 15 are provided with limiting screws inside. The two sets of fixing plates 15 are fixedly connected to the connecting frame 11 by the limiting screws. One end of the connecting rod 16 is located on the outer wall of the connecting frame 11 and a power motor 14 is installed. The tilting frame 12 is rotated along the inside of the connecting frame 11 by the connecting rod 16.

[0024] Please see Figures 4-5Multiple sets of guardrails 13 are installed on the inner wall of the connecting frame 11. The multiple sets of guardrails 13 are welded to the connecting frame 11 for positioning. A positioning plate is installed and welded to the lower end of the harvester 1. Two sets of tracks 17 are provided on the outer wall of the positioning plate. The harvester 1 is installed and fixed to the two sets of tracks 17 through the positioning plate. A collection box 18 is provided at the lower end of the positioning plate. One end of the collection box 18 is located on one side of the tilting frame 12 and has an inlet.

A guide plate 20 is welded to one end of the collection box 18 below the sealing plate 19.

[0025] When harvesting with harvester 1, first use the fixing bolts 9 and connecting blocks 8 to install baffle 7 at the lower end of movable plate 3. During the subsequent cutting and pulling process, this prevents the beet green tops and beet roots from being collected together, reducing the need for subsequent cleaning of the green tops and speeding up the harvesting process. After baffle 7 is installed, check the actual height of the beet leaves and control the rotary motor 10 connected to the rotating rod to drive the movable frame to rotate and adjust the cutting position of blade 5. This avoids cutting too much or too little when using blade 5 to cut the beet leaves later, flexibly responding to different cutting variations, fully removing the beet green tops, and ensuring optimal cutting efficiency in different fields and growing conditions. To reduce waste of beet root materials and ensure the integrity of beet harvesting, a filter bag is used to drive the harvester 1 to move along the field and cut beet leaves. At the same time, the power motor 14, combined with the connecting rod 16, rotates the turning frame 12, inserting it into the soil where beets need to be pulled. Through the linear movement of the harvester 1, the beet roots with cut leaves are pulled out of the soil. According to the preset rotation time of the connecting rod 16 driven by the power motor 14, after a brief pulling of beet roots, the connecting rod 16 is driven to rotate counterclockwise, so that the turning frame 12 can pour the pulled beet root pieces into the collection box 18 for collection, thus realizing the harvesting of beet leaves.
