Description

Technical Field

[0001] This utility model relates to vegetable harvesting machinery, specifically a collection and unloading device for a cabbage harvester. Background Technology

[0002] Cabbage is one of the main vegetable varieties, but compared with grain production, the level of mechanization in vegetable production is relatively backward. For a long time, cabbage harvesting has still relied mainly on manual labor, which is characterized by low labor efficiency, high labor intensity, poor work quality, and high production costs.

[0003] In recent years, the applicant, together with the Nanjing Institute of Agricultural Mechanization of the Ministry of Agriculture and Rural Affairs, has jointly conducted research and development on cabbage harvesting machinery, and designed a series of cabbage harvesting machines. The published authorized invention patent of the Nanjing Institute of Agricultural Mechanization of the Ministry of Agriculture and Rural Affairs, "Cabbage Harvester" (patent number 2021101436874), consists of a walking mechanism, a harvesting mechanism, and a transmission mechanism. Its features include a walking mechanism comprising a chassis assembly and two track assemblies. The width of the chassis frame and the distance between the two track assemblies are adjustable via sliders and hydraulic cylinders mounted on the chassis frame. The harvesting mechanism and the transmission mechanism are both mounted on the walking mechanism and can move together with it.

[0004] The applicant has two utility model patents. One is a ride-on tracked cabbage harvester with patent number 202222949244.7, which includes a header assembly, a tracked power chassis, a cabbage conveying mechanism assembly, a cab, and a diesel engine. The header assembly is modularly and integrally mounted on the front end of the frame, achieving both vertical and tilting lifting functions through lifting and tilting cylinders. A figure-eight-shaped stripping roller is installed above the transverse conveyor belt, with a speed difference between the stripping roller on the same side and the transverse conveyor belt, allowing for dynamic stripping of cabbage waste leaves during transport. An electronic display screen in the cab allows for dynamic monitoring of harvesting, conveying, and stripping. The machine is driven by a tracked hydraulic continuously variable transmission power chassis. The overall structure is reasonable, with high operating efficiency, safe and stable travel, continuously variable transmission, convenient operation, and a high degree of informatization, enabling fully mechanized cabbage harvesting.

[0005] The second patent, number 2022208712019, discloses a hand-held self-propelled cabbage harvester with a hand-held self-propelled chassis and a T-shaped conveyor belt positioned directly below the frame. This patent uses a gasoline engine as its power source and suspends a single-row cutting platform assembly via the hand-held self-propelled chassis. The difference between this patent and the aforementioned patent is that it uses a gasoline engine, a hand-held self-propelled chassis, and the entire machine is compact, flexible, easy to use, and low-cost, capable of harvesting single rows of cabbage.

[0006] However, the above-mentioned institutions have the following drawbacks: all equipment and institutions only harvest cabbage, but do not collect and sort the harvested cabbage. Manual assistance is required behind the machine to bag the cabbage, which reduces the collection efficiency. When the harvesting efficiency is high, the manual labor behind the machine cannot bag the cabbage in time. When the machine turns around to harvest, it is easy to crush the unbagded cabbage, causing damage to the cabbage. Summary of the Invention

[0007] The purpose of this utility model is to provide a collection and unloading device for a cabbage harvester to solve the problems existing in the background art.

[0008] The technical solution of this utility model includes two or more sets of supporting columns (1) and a frame (2) set on top of them.

The lower front end of the collection box (3) is hinged to the top of the frame (2) via a rotating shaft (12) and a bearing seat (11). The lower rear end of the collection box (3) is equipped with an electric push rod (7) that allows the collection box (3) to be rotated as a whole. The electric push rod (7) is hinged to the supporting columns (1). 1) The front side of the collection box (3) is provided with a front side plate (6) that can be opened or closed. The two are connected by a hinge. An electric push rod (5) is provided between the collection box (3) and the front side plate (6) to open or close the front side plate (6). The two ends of the electric push rod (5) are respectively hinged to the collection box (3) and the front side plate (6). Rollers (9) are evenly distributed on the entire bottom surface of the collection box (3). The rollers (9) are fixed between the brackets (8) by the shaft. The brackets (8) are fixed to the bottom of the collection box frame (4), and the top of the rollers (9) is higher than the inner bottom surface of the collection box frame (4).

[0009] The collection box (3) is provided with conveyor platforms (14) on both sides of the top. The conveyor platforms (14) are equipped with fences (13). The conveyor platforms (14) are independently driven by the conveyor belt motor (16) located at the front end.

[0010] The conveyor platforms (14) on both sides are equipped with guide plates (15) corresponding to the fence (13).

[0020] See Figure 1-3 A collection and unloading device for a cabbage harvester includes two or more sets of support columns 1 and a frame 2 mounted on top of them. Only one set of rear support columns 1 is shown in the figure. To illustrate the hinge position of the electric push rod 7, the other support columns 1 only serve to support the frame 2 and are not shown in the figure.

[0021] The frame 2 is equipped with a collection box 3, which consists of a collection box frame 4 and a mesh guardrail welded to the collection box frame 4. The bottom of the collection box 3 is equipped with no fewer than two reinforcing ribs 10. The front end of the collection box 3 is equipped with a bearing seat 11 and fixed to the reinforcing rib 10, and then hinged to the top of the frame 2 through a rotating shaft 12. The rear end of the collection box 3 is equipped with a support hinged to the output end of the electric push rod 7, which is also located on the reinforcing rib 10. The two ends of the electric push rod 7 are respectively hinged to the supporting column 1 and the support below the collection box 3. The extension and retraction of the electric push rod 7 drives the collection box 3 to rotate around the rotating shaft 12 as the fulcrum, thereby realizing unloading.

[0022] The front end of the collection box 3 is provided with a front side plate 6 and the two are connected by a hinge. An electric push rod 5 is also provided between the collection box 3 and the front side plate 6. The two ends of the electric push rod 5 are respectively hinged to the collection box 3 and the front side plate 6. The extension and retraction of the electric push rod 5 drives the opening and closing of the front side plate 6.

[0023] Meanwhile, in order to improve the efficiency of unloading, the bottom of the collection box 3 is covered with evenly distributed rollers 9. The rollers 9 are fixed between the brackets 8 by the shaft. The brackets 8 are fixed to the bottom of the collection box 3, and the top of the rollers 9 is higher than the inner bottom surface of the collection box frame 4. In this way, when the cabbage is unloaded, it will automatically fall down the slope from the front side plate 6 under the action of gravity and the rollers.

[0024] The mesh guardrails on the collection box 3 and the front panel 6 are used to prevent the cabbage from falling out, and at the same time, they make it easier to observe the cabbage collection situation inside the collection box 3. Example 2:

[0025] See Figure 4 Based on Embodiment 1, a conveyor platform 14 is added to both sides of the top of the collection box 3. The front and rear ends of the conveyor platform 14 are respectively provided with guide plates 15 and fences 13. The conveyor platform 14 is driven by a conveyor belt motor 16 located at the front end. The cabbage falls from both sides onto the conveyor platform 14 and then moves forward. The fence 13 prevents the cabbage from falling outside the collection box 3. The guide plates 15 guide the cabbage to the conveyor platforms 14 on both sides, and then smoothly guide the cabbage into the collection box 3. Example 3:

[0026] See Figure 5 Based on Embodiment 2, the guide plate 15 is removed, and a vegetable equalizer 17 is set in the middle of the collection box 3, spanning between the two conveyor tables 14. The two ends of the vegetable equalizer 17 are supported on the collection box frame 4 by the slider rail 20, and slide on the collection box frame 4. The middle part of the vegetable equalizer 17 is driven to slide by the equalizer motor 19 and the electric push rod 18 set on the collection box frame 4.
