Description

Technical Field

[0001] This utility model relates to a crop harvesting device, specifically a front straightening mechanism and a front straightening device. Background Technology

[0002] For stalk-shaped crops such as sugarcane, they need to be straightened before harvesting and other subsequent operations can be carried out. An invention patent filed on May 2, 2023, discloses a straightening mechanism and device. This straightening mechanism uses a straightening chain to drive a straightening actuator in a cyclical movement, achieving continuous straightening of a single row of plants. The straightening device consists of two symmetrically arranged straightening mechanisms that, during operation, are positioned on either side of the single row of plants, working together to straighten any plants that have fallen to the left or right in that row.

[0003] However, stalk crops are typically planted in multiple rows. When existing straightening mechanisms are used to straighten a row of crops, the fallen crops on either side of that row interfere with the mechanism's operation. This significantly reduces straightening efficiency and severely impacts the straightening effect, making it difficult to meet the practical needs of large-scale agricultural production. Therefore, a new type of front straightening mechanism and device is needed to solve this problem. Utility Model Content

Detailed Implementation

[0038] like Figures 1-2 As shown, this utility model provides a front straightening mechanism, which mainly includes a frame 1, a middle straightening component 2 and a side material feeding component 3, wherein the middle straightening component 2 and the side material feeding component 3 are located on both sides of the frame 1.

[0039] The frame 1 includes a main frame 11, a support rod 12, and a reinforcing rod 13. The support rod 12 is arranged laterally, and one end of the support rod 12 is fixedly connected to the middle of the bottom of the main frame 11. One end of the reinforcing rod 13 is fixedly connected to the main frame 11, and the other end is fixedly connected to the other end of the support rod 12. The frame 1 in this invention has a reasonable structural design, high strength and stability, and can provide reliable support for the entire front straightening mechanism 10.

[0040] The intermediate straightening component 2 includes a first flexible transmission device 21 and straightening actuating elements 22. The first flexible transmission device 21 is mounted on the frame 1, with its bottom inclined forward and its top inclined from front to back away from the side-pushing component 3. Multiple straightening actuating elements 22 are spaced apart on the outer surface of the first flexible transmission device 21. This inclined arrangement effectively straightens tilted plants. The side-pushing component 3 includes a second flexible transmission device 31 and side-pushing elements 32. The second flexible transmission device 31 is mounted on the frame 1, with its bottom inclined forward and its top inclined from front to back away from the intermediate straightening component 2. Multiple side-pushing elements 32 are spaced apart on the outer surface of the second flexible transmission device 31. The intermediate straightening component 2 and the side-pushing component 3 work together to straighten plants from both sides, greatly improving the efficiency and effectiveness of straightening.

[0041] The first flexible transmission device 21 and the second flexible transmission device 31 have the same structure, both including a drive sprocket 01, a driven sprocket 02, and a chain 03. The drive sprocket 01 is rotatably mounted on the main frame 11. The driven sprockets 02 of both the first flexible transmission device 21 and the second flexible transmission device 31 are rotatably mounted at the end of the support rod 12 away from the main frame 11 and located below the drive sprocket 01. The chain 03 is driven and sleeved on the drive sprocket 01 and the driven sprocket 02 to realize the transmission of power. The straightening and shifting component 22 and the side shifting component 32 are mounted on the chain 03, and the plant is straightened by the transmission of the chain 03. The transmission method of the sprocket and the chain 03 has the advantages of high transmission efficiency and good stability. The cooperation between the frame 1 and the drive sprocket 01 and the driven sprocket 02 effectively realizes the inclined design of the intermediate straightening component 2 and the side shifting component 3. In this embodiment, to prevent the chain 03 from derailing during operation, baffles 4 are provided on the outer sides of both chains 03. The two ends of the baffles 4 are rotatably connected to the driving sprocket 01 and the driven sprocket 02, respectively. The baffles 4 not only protect the chains 03, but also limit the movement of the straightening actuator 22 and the side actuator 32, and effectively prevent plant leaves from entering between the sprockets of the chains 03 and affecting normal transmission.

[0042] The drive sprocket 01 of the first flexible transmission device 21 and the drive sprocket 01 of the second flexible transmission device 31 are synchronously connected via a transmission device 6. The transmission device 6 includes a first pulley 61, a second pulley, a belt 62, and a steering mechanism. The first pulley 61 is rotatably mounted on the top of the main frame 11 and is the drive pulley, which can be synchronously driven to rotate by the drive devices of other components of the harvester. The second pulley (not shown) is rotatably mounted on the top of the main frame 11 and located below the first pulley 61. A belt 62 is sleeved between the first pulley 61 and the second pulley. The second pulley is rotatably connected to both drive sprockets 01 via a steering mechanism (not shown), realizing the transmission of power and the conversion of the transmission direction. The outer sides of the first pulley 61, the second pulley, the belt 62, and the steering mechanism are all covered with a housing to prevent impurities from entering and affecting the transmission of the drive sprockets 01. In this embodiment, the converter can be a bevel gear drive, a worm gear drive, or a universal joint drive; these are existing technologies and will not be described in detail here.

[0043] The straightening actuating component 22 includes a first stop 221 and a first lever 222. The first stop 221 is fixedly mounted on the chain 03. One end of the first lever 222 is fixedly mounted on the chain 03, and the other end extends away from the side-shifting component 3, used to shift the plant to gradually restore it to an upright position. The side-shifting component 32 includes a second stop 321 and a second lever 322. The second stop 321 is fixedly mounted on the chain 03. One end of the second lever 322 is fixedly mounted on the chain 03, and the other end extends away from the central straightening component 2. The side-shifting component 32 works in conjunction with the straightening actuating component 22 to straighten the plant on the other side.

[0044] Both the top of the intermediate straightening component 2 and the top of the side feeding component 3 are equipped with arc-shaped guide rods 5. One end of the arc-shaped guide rod 5 is fixedly connected to the inner side of the baffle 4, and the other end passes around the top of the chain 03 and is fixedly connected to the frame 1. The middle part of the arc-shaped guide rod 5 extends outward. The arc-shaped guide rod 5 can guide the plant to pass smoothly through the straightening mechanism, avoiding the plant from getting stuck or tangled at the top, further improving the straightening efficiency and effect.

[0045] When the equipment starts working, the first pulley 61 rotates, transmitting power to the second pulley via the belt 62. The second pulley drives the two drive sprockets 01 to rotate synchronously via a steering mechanism. The drive sprockets 01 drive the chain 03, causing the straightening actuating element 22 and the side actuating element 32 on the chain 03 to move accordingly. During the forward movement of the equipment, the straightening actuating element 22 and the side actuating element 32 straighten the plants. Specifically, the two driven sprockets 02 at the front end extend between the two rows of plants, and the straightening actuating element 22 of the middle straightening component 2 and the side actuating element 32 of the side actuating component 3 straighten the plants on both sides respectively. During the straightening process, the first lever 222 and the second lever 322 actuate the plants, causing each plant to return to an upright position in sequence. The arc-shaped guide rod 5 guides the plants smoothly through the straightening mechanism, preventing the plants from getting stuck or tangled at the top.

[0046] like Figure 3 As shown, this utility model also provides a front straightening device, including two front straightening mechanisms 10, which are symmetrically arranged, and two intermediate straightening components 2 are located between two side feeding components 3, with a space between the two intermediate straightening components 2 for the plant to pass through.

[0047] The front straightening device is installed at the front of the harvesting equipment. During operation, the two front straightening mechanisms 10 are located on both sides of a row of plants. The two front straightening mechanisms 10 work simultaneously, while the middle straightening component 2 straightens the plants that have fallen to the left and right in the row, ensuring that all plants are in the middle position, preparing them for subsequent harvesting operations. At the same time, the side feeding component 3 straightens the plants on both sides of the row outwards, preventing them from interfering with the straightening work of the plants in the row.
