Description

Technical Field

[0001] The invention relates to crop harvesting equipment, in particular to a straightening mechanism and a straightening device. Background Art

[0002] For pole-shaped crops such as sugarcane, they need to be straightened before harvesting and other subsequent operations. When harvesting pole-shaped crops such as sugarcane, the straightening is achieved by straightening rollers. The structure of the straightening rollers is a circular roller with spiral blades on its surface. This straightening structure is large in size and weight, and in order to obtain a better straightening effect, the angle between the straightening roller and the horizontal plane needs to be set smaller, which causes the straightening roller to be extended too long, thereby increasing the turning radius of the harvester. At the same time, due to its large size and weight, the harvester cannot be miniaturized. Large harvesters are too heavy and will cause irreparable damage to the ridges during operation. Summary of the invention

[0003] The purpose of the present invention is to provide a righting mechanism and a righting device to solve the problems of the existing righting devices being large in size, weight, long in length and having poor righting effect.

[0004] The present invention is implemented as follows: a straightening mechanism includes a frame, on which a first sprocket and a second sprocket located below the first sprocket are arranged, the second sprocket is located in front of the first sprocket, and the second sprocket is located on the outside of the first sprocket in the left and right direction, a straightening chain is installed on the first sprocket and the second sprocket, and straightening and moving parts for moving plants are distributed at intervals on the straightening chain.

[0005] The straightening toggle member comprises a toggle rod, which is directly fixed on the straightening chain or fixed on the straightening chain through a stopper, the toggle rod is perpendicular to the plane where the straightening chain is located, and the toggle rod extends inward in the left-right direction.

[0006] The stopper is fixed on the link of the straightening chain, the stopper is located on the plane where the straightening chain is located, and the shifting rod is fixed on the end of the stopper.

[0007] A front outrigger extending forward and downward is arranged at the lower part of the frame, and the second sprocket is installed at the front end of the front outrigger.

[0008] The present invention also discloses a straightening device, comprising two symmetrically arranged straightening mechanisms, with a space for plants to pass through left and right between the two straightening mechanisms. The straightening mechanism comprises a frame, on which a first sprocket and a second sprocket located below the first sprocket are arranged, the second sprocket being located in front of the first sprocket and at the same time being located on the outside of the first sprocket in the left-right direction. A straightening chain is installed on the first sprocket and the second sprocket, and straightening and moving parts for moving the plants are distributed at intervals on the straightening chain.

[0009] The straightening toggle member comprises a toggle rod, which is directly fixed on the straightening chain or fixed on the straightening chain through a stopper, the toggle rod is perpendicular to the plane where the straightening chain is located, and the toggle rod extends inward in the left-right direction.

[0010] The stopper is fixed on the link of the straightening chain, the stopper is located on the plane where the straightening chain is located, and the shifting rod is fixed on the end of the stopper.

[0011] A front outrigger extending forward and downward is arranged at the lower part of the frame, and the second sprocket is installed at the front end of the front outrigger.

[0012] It also includes a front-to-back alignment mechanism arranged at the rear of the frame, the front-to-back alignment mechanism includes a third sprocket and a fourth sprocket located below the third sprocket, the fourth sprocket is located in front of the third sprocket, an alignment chain is installed on the third sprocket and the fourth sprocket, and alignment shifting parts for shifting plants are distributed at intervals on the alignment chain.

[0013] The positioning shifting member comprises a shifting rod, which is directly fixed on the positioning chain or fixed on the positioning chain through a stopper, and the shifting rod is parallel to the plane where the positioning chain is located, and the shifting rod is perpendicular to the positioning chain.

[0014] The straightening mechanism of the present invention is used for the straightening operation of pole-shaped plants such as sugarcane. The present invention drives the movement of the straightening chain through a sprocket. The straightening toggle member on the straightening chain gradually moves upward from the bottom, and at the same time moves from the front to the rear and from the outside to the inside. The straightening mechanism moves forward during operation. If the plant tilts in the left and right directions, the plant will gradually approach the straightening chain in the left and right directions, and will eventually be contacted and toggled by the straightening toggle member. Under the toggling of the straightening toggle member, the plant gradually swings inward, thereby achieving the straightening of the plant.

[0015] For the existing righting roller, the round roller has a certain diameter, and spiral blades are arranged on the surface of the round roller. The overall volume and weight are relatively large, and the power required to drive the righting roller is also large. At the same time, a high-strength bracket is required to install and support the righting roller. The most direct way to increase the strength of the bracket is to increase the material of the bracket, thereby further increasing the weight of the device. The sprocket chain structure adopted by the present invention has a small volume and weight, and the required driving force and supporting force are also small.

[0016] The straightening chain drives the straightening toggle member to move cyclically, thereby realizing the continuous straightening operation of a row of plants.

[0017] The spaced-apart straightening toggle members are used to straighten different plants, and each straightening toggle member acts on only one plant, so that adjacent plants can be clearly distinguished for subsequent processing.

[0018] With the structure of the present invention, the angle between the righting chain and the horizontal plane can be designed to be larger, and the front sprocket can be directly installed on the front extension frame without the need for complex connection structures such as bearings, thereby shortening the previous extension length of the righting mechanism.

[0019] The righting device includes two symmetrically arranged righting mechanisms. When working, the two righting mechanisms are located on both sides of a row of plants. The two righting mechanisms work simultaneously to right the left and right fallen plants in a row of plants, so that all plants are located in the middle position for subsequent processing.

[0020] The straightening mechanism of the present invention has small volume, light weight and short length, and is easy to realize miniaturization of the harvester. When in use, it has a small turning radius, is easy to operate, has a small overall weight, and will not cause serious damage to the field ridges. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1~Figure 4 As shown, the straightening mechanism of the present invention includes a frame 1, on which a first sprocket 2 and a second sprocket 4 are arranged, the second sprocket 4 is located below the first sprocket 2, and the second sprocket 4 is located in front of the first sprocket 2. At the same time, the second sprocket 4 is located outside the first sprocket 2 in the left and right direction, and a straightening chain 5 is installed on the first sprocket 2 and the second sprocket 4. Straightening and moving parts 6 for moving plants are distributed at intervals on the straightening chain 5.

[0029] The straightening chain 5 installed on the first sprocket 2 and the second sprocket 4 is tilted forward and downward, and its lower part is also tilted outward, so that the straightening toggle member 6 installed on the straightening chain 5 moves upward along the inclined straight line while also moving backward and inward.

[0030] The straightening mechanism is used to straighten plants that are tilted to one side toward the middle. When working, the entire straightening mechanism moves forward at a certain speed. Since the straightening chain 5 has a certain inclination angle in the left and right directions, when the chain moving forward with the frame 1 contacts the tilted plant, the plant is moved by the straightening mechanism, and the straightening push piece 6 moves backward in the front and rear directions at the same speed as the forward speed of the straightening mechanism. Therefore, the plant will not swing in the front and rear directions, but will only swing inward along with the straightening push piece 6. After the plant passes through the entire straightening mechanism, all the plants that are tilted to one side are straightened.

[0031] The righting toggle member 6 includes a lever 8 which is directly fixed on the righting chain 5 or fixed on the righting chain 5 through a stopper 7. The lever 8 is perpendicular to the plane where the righting chain 5 is located, and extends inward in the left-right direction.

[0032] When the shifting rod 8 is fixed on the stopper 7 , the stopper 7 is fixed on the link of the righting chain 5 , the stopper 7 is located on the plane where the righting chain 5 is located, and the shifting rod 8 is fixed on the end of the stopper 7 .

[0033] The tilted plant leans outwardly on the chain or block 7. Since the chain is tilted, the plant tends to move forward when leaning on the chain or block 7. The lever 8 extending inwardly can hook the plant. When moving, the straightening and pushing member 6 moves relatively upward along the plant, thereby stably pushing the plant inwardly through the straightening and pushing member 6.

[0034] A front outrigger 3 extending forward and downward is provided at the lower part of the frame 1 , and a second sprocket 4 is mounted at the front end of the front outrigger 3 . The second sprocket 4 is mounted by the front outrigger 3 extending forward and downward.

[0035] Generally, the first sprocket 2 is used as a driving sprocket and the second sprocket 4 is used as a driven sprocket.

[0036] The axis direction of the first sprocket 2 and the second sprocket 4 is generally in the left-right direction, and the inclination angle of the axis is determined by the inclination angle of the straightening chain 5. When the sprocket drives the straightening chain 5 to move, the straightening toggle 6 continuously moves from the rear side of the straightening chain 5 to the front side and then to the rear side. Since the axis of the sprocket is inclined, the lever 8 of the straightening toggle 6 moved to the rear side of the straightening chain 5 extends inward, but compared with the straightening toggle 6 located at the front side of the straightening chain 5 at the same height, the straightening toggle 8 is located on the outside as a whole. Therefore, the inclined plant can only contact the straightening toggle 6 located at the front side of the straightening chain 5, but not the straightening toggle 6 located at the rear side of the straightening chain 5, thereby avoiding the interference of the straightening toggle 6 located at the rear side of the straightening chain 5 with the straightening operation.

[0037] The straightening mechanism of the present invention adopts a sprocket chain structure, which is easy to install, and only needs to determine the positions of the first sprocket 2 and the second sprocket 4. Among them, the volume and weight of the sprocket and the chain are very small, so the driving force and supporting force required are also very small, and only a conventional frame 1 is needed to achieve the installation and support of the sprocket. However, for the existing straightening roller, since the round roller has a certain diameter and spiral blades are provided on the surface of the round roller, its overall volume and weight are relatively large, and the power required to drive the straightening roller is also large, so a high-strength bracket is required to install and support the straightening roller, and the most direct way to increase the strength of the bracket is to increase the material of the bracket, thereby further increasing the overall weight of the mechanism.

[0038] At the same time, the spaced-apart straightening toggle members 6 on the toggle mechanism of the present invention are used to straighten different plants, and each straightening toggle member 6 acts on only one plant, so that adjacent plants can be clearly distinguished for subsequent processing. The straightening chain 5 drives the straightening toggle members 6 to move cyclically, so that a row of plants can be straightened continuously.

[0039] In this structure of the present invention, the angle between the straightening chain 5 and the horizontal plane can be designed to be larger, and different plants are toggled by different straightening toggle members 6, and different plants will not affect each other. And the front sprocket can be directly installed on the front extension frame 3, and it is not necessary to install the straightening roller on the frame 1 through a bearing like the existing straightening roller, and the lower end of the frame 1 needs a corresponding strength reinforcement structure to enable it to bear the weight of the straightening roller, thereby shortening the length of the straightening mechanism previously extended, and it can be easily moved during work.

[0040] like Figure 5 , Figure 6 As shown, the present invention also discloses a straightening device, including two symmetrically arranged straightening mechanisms, with a space for plants to pass through left between the two straightening mechanisms, the straightening mechanism including a frame 1, a first sprocket 2 is arranged on the frame 1, the first sprocket 2 and a second sprocket 4 located below the first sprocket 2 are arranged on the frame 1, the second sprocket 4 is located in front of the first sprocket 2, and the second sprocket 4 is located on the outside of the first sprocket 2 in the left and right direction, a straightening chain 5 is installed on the first sprocket 2 and the second sprocket 4, and straightening and shifting parts 6 for shifting plants are distributed at intervals on the straightening chain 5.

[0041] The righting toggle member 6 includes a lever 8 which is directly fixed to the righting chain 5 or fixed to the righting chain 5 via a stopper 7. The lever 8 is perpendicular to the plane where the righting chain 5 is located, and extends inward in the left-right direction.

[0042] The stopper 7 is fixed on the link of the righting chain 5 , the stopper 7 is located on the plane where the righting chain 5 is located, and the shifting rod 8 is fixed on the end of the stopper 7 .

[0043] A front outrigger 3 extending forward and downward is provided at the lower portion of the frame 1 , and a second sprocket 4 is mounted at the front end of the front outrigger 3 .

[0044] The two straightening mechanisms are symmetrically arranged to form a straightening device, with a space in the middle for plants to pass through. When working, the straightening device moves forward along the direction of the middle row of plants, thereby straightening the plants in a row that are tilted to the left and right sides.

[0045] In addition to the left-right straightening of the plant, the plant can also be aligned in the front-back direction at the same time. A front-back straightening mechanism is provided at the rear of the frame 1 of each straightening mechanism, and the two front-back straightening mechanisms are symmetrical to each other.

[0046] The front and rear alignment mechanism includes a third sprocket 9 and a fourth sprocket 10 located below the third sprocket 9. The fourth sprocket 10 is located in front of the third sprocket 9. An alignment chain 11 is installed on the third sprocket 9 and the fourth sprocket 10. Alignment members 12 for moving plants are spaced apart on the alignment chain 11.

[0047] The tilt angle of the alignment chain 11 is large to ensure that the plants tilted forward and backward can be straightened to the middle during operation. For plants tilted forward, the plants come into contact with the alignment toggle 12 later, but since the angle of the alignment chain 11 is large, the alignment toggle 12 quickly straightens the plants backwards during the upward movement after contact; and for plants tilted backward, the plants come into contact with the alignment toggle 12 very early, and after contact, the alignment toggle 12 straightens the plants forwards.

[0048] The front-to-back positioning mechanism moves forward at a certain speed together with the random frame 1. For the plants that have been straightened left and right, if there is no tilt in the front-to-back direction, the plants will directly pass through the front-to-back positioning mechanism. If there is a tilt in the front-to-back direction, during the movement of the front-to-back positioning mechanism, the positioning toggle member 12 moving from bottom to top along the tilted positioning chain 11 will contact the plant and lift the tilted plant to straighten it.

[0049] The righting toggle member 12 includes a lever 8 , which is directly fixed on the righting chain 11 or fixed on the righting chain 11 through a stopper 7 . The lever 8 is parallel to the plane where the righting chain 11 is located, and the lever 8 is perpendicular to the righting chain 11 .

[0050] When the positive positioning member 12 is moving the plant, there is no displacement in the left-right direction, so the third sprocket 9 and the fourth sprocket 10 need not be offset in the left-right direction, so the axis of the third sprocket 9 and the fourth sprocket 10 needs to be set to an approximate front-to-back direction, so that when working, the positive positioning member 12 will move from the outside of the frame 1 to the inside of the frame 1, and then from the inside of the frame 1 back to the outside of the frame 1. The positive positioning member 12 moved to the outside of the frame 1 will not interfere with the positive positioning member 12 on the inside.

[0051] By straightening the plants left and right in the front and back, the plants can be straightened in both directions, to facilitate subsequent processing of the plants.

[0052] The righting mechanism and the front and rear positioning mechanisms are driven by the same power source, and the power is distributed through the gearbox and the transmission mechanism to achieve the linkage between the righting mechanism and the front and rear positioning structures, and its movement speed matches the moving speed of the vehicle body.

[0053] The frame 1 equipped with the straightening mechanism and the front-rear alignment mechanism is installed on the vehicle body through an adjustable frame. The height of the frame 1 is adjusted through the adjustable frame, thereby adjusting the height of the straightening mechanism and the front-rear alignment mechanism.

[0054] Since the whole structure of the righting mechanism and the righting device of the present invention is small in size, light in weight, and short in overall length, it is very beneficial to the miniaturization of the harvester of pole-shaped crops, especially the sugarcane harvester. The short length of the righting device at the front end of the entire harvester is beneficial to the reduction of the turning radius, and is beneficial to the flexible operation of the harvester in the field. After the harvester is miniaturized, the weight of the vehicle body is small. At the same time, the small weight of the righting device can reduce the overall mass of the harvester, so the damage of the harvester to the field ridge can be greatly avoided during operation. For sugarcane, the roots left in the soil after harvesting are used for re-branching and stem growth. If they are severely crushed, they will cause fatal damage, which requires investigation and replanting, thereby causing economic losses to farmers. Therefore, reducing the weight of the harvester and reducing the damage caused by crushing the roots of sugarcane will greatly reduce the economic losses of farmers.

[0055] The straightening mechanism of the present invention is used for straightening operations of pole-shaped plants such as sugarcane. The present invention drives the movement of the straightening chain 5 through a sprocket. The straightening toggle member 6 on the straightening chain 5 gradually moves upward from the bottom, and at the same time moves from the front to the rear and from the outside to the inside. The straightening mechanism moves forward during operation. If the plant tilts in the left and right directions, the plant will gradually approach the straightening chain 5 in the left and right directions, and will eventually be contacted and toggled by the straightening toggle member 6. Under the toggling of the straightening toggle member 6, the plant gradually swings inward, thereby achieving the straightening of the plant.

[0056] The righting device includes two symmetrically arranged righting mechanisms. When working, the two righting mechanisms are located on both sides of a row of plants. The two righting mechanisms work simultaneously to right the left and right fallen plants in a row of plants, so that all plants are located in the middle position for subsequent processing.

[0057] The straightening mechanism of the present invention has small volume, light weight and short length, and is easy to realize miniaturization of the harvester. When in use, it has a small turning radius, is easy to operate, has a small overall weight, and will not cause serious damage to the field ridges.
