Description

Technical Field

[0001] The invention relates to a harvesting device, in particular to a front-to-back positioning device and a front-to-back positioning method for rod-shaped plants. Background Art

[0002] When sugarcane and other pole-shaped plants are harvested mechanically, the plants need to be arranged and straightened first. After being straightened, they are easy to harvest and process. The existing straightening mechanism is generally a straightening roller. The structure of the straightening roller is that spiral blades are arranged on the surface of the round roller. The rotation of the round roller drives the spiral blades to rotate, thereby driving the plants to move from both sides to the middle along the inclined round roller to straighten the plants. The existing straightening rollers are used for left and right straightening, and mainly rely on the left and right inclined straightening rollers to gather the plants to the middle, and cannot straighten the plants in the front and back directions. In addition, the existing straightening rollers are large in size and weight, and occupy a large space, which is not conducive to the miniaturization and lightweight of the harvester. At the same time, since the existing sugarcane harvesting equipment does not consider the problem of the sequential arrangement of the plants, the existing straightening rollers are not suitable for the front and rear straightening of the plants. If the existing straightening rollers are used for the front and rear alignment operation, the plants can only be driven to align front and rear by the spiral blades on the surface of the straightening rollers. The plants are easy to fall off the spiral blades, thereby failing to achieve the expected alignment effect. Summary of the invention

[0003] The purpose of the present invention is to provide a rod-shaped plant front-to-back alignment device and a front-to-back alignment method to solve the problem that the existing alignment devices are large in size and weight and are not suitable for front-to-back alignment of plants.

[0004] The present invention is achieved as follows: a front-to-back alignment device for rod-shaped plants, comprising two front-to-back alignment mechanisms that are symmetrically arranged left and right, a alignment channel between the two front-to-back alignment mechanisms, the front-to-back alignment mechanisms comprising a first transmission wheel and a second transmission wheel that are arranged on a frame, the first transmission wheel being located above the second transmission wheel, the first transmission wheel and the second transmission wheel being located in the same plane, the upper part of the plane being tilted backward, and the first transmission wheel and the second transmission wheel being aligned left and right in the front-to-back direction, the first transmission wheel and the second transmission wheel being transmitted through a flexible transmission member, and material shifting members being arranged at intervals on the flexible transmission member; the material shifting members on the two front-to-back alignment mechanisms for rod-shaped plants correspond one to one.

[0005] The material shifting member comprises a material shifting rod, which is directly arranged on the flexible transmission member or arranged on the flexible transmission member through a material shifting block, and the material shifting rod extends outward from the flexible transmission member.

[0006] The material moving rod is parallel to the plane where the flexible transmission member is located, and the material moving rod is perpendicular to the flexible transmission member.

[0007] A gap is left between the ends of the material-moving rods on both sides of the correct channel, and the gap is smaller than the diameter of the rod-shaped plant. The ends of the material-moving rods are in a smooth arc shape.

[0008] The first transmission wheel and the second transmission wheel are sprockets, and the flexible transmission member is a chain.

[0009] The material-diverting members and the flexible transmission members are evenly arranged, and the distance between two adjacent material-diverting members in the front-to-back direction can accommodate a rod-shaped plant.

[0010] The present invention also discloses a method for front-to-back alignment of rod-shaped plants, which is implemented based on the aforementioned front-to-back alignment device for rod-shaped plants, so that the front-to-back alignment device for rod-shaped plants moves forward as a whole along a row of plants, and the first transmission wheel or the second transmission wheel drives the material-pushers to move in a circular motion, and the outer material-pushers enter the alignment channel from below the front-to-back alignment mechanism in turn, and the horizontal component speed of the material-pushers moving backward is made to be the same as the speed of the overall forward movement of the device; the plants pass through the alignment channel between the two front-to-back alignment mechanisms, and the materials-pushers on both sides straighten the plants in turn.

[0011] For a plant that is tilted backward, the material-pushing piece located at the rear of the plant gradually straightens the plant forward around its root until one of the material-pushing pieces enters the front of the plant, and the plant is restricted to a vertical state by the front and rear two material-pushing pieces.

[0012] For a plant that is tilted forward, when a material-pushing member enters in front of the plant, the material-pushing member straightens the plant backward around its root to a vertical state.

[0013] The front-to-back positioning device for rod-shaped plants of the present invention realizes the front-to-back positioning of the plants through a flexible transmission member transmission wheel structure and a material-shifting member. When working, the front-to-back positioning device moves forward as a whole, so that the rod-shaped plants gradually enter the positioning channel of the front-to-back positioning device, and the material-shifting member entering the inner side of the flexible transmission member moves upward from the bottom. When the plant tilted forward or backward encounters the material-shifting member, the material-shifting member shifts the plant so that it gradually becomes vertical.

[0014] Since the material-push-piece moves from the outside of the straightening mechanism to the inside of the straightening mechanism, for a plant tilted forward, the material-push-piece is inserted from the gap near the root position at the lower front part of the plant, and then the material-push-piece gradually moves upward along the flexible transmission member, thereby straightening the plant backward; and for a plant tilted backward, the material-push-piece is inserted from the gap near the root position at the lower rear part of the plant, and then the material-push-piece gradually moves upward along the flexible transmission member, thereby straightening the plant forward.

[0015] The spaced-apart material shifting pieces can sequentially adjust the front-to-back position of different plants. After adjustment, the plants are in a vertical state. At the same time, the adjacent plants can be spaced apart, and the plants are arranged sequentially according to the front-to-back position of the roots.

[0016] The rod-shaped plant front-to-back alignment device of the present invention is very small in size and weight, occupies a small space, and is convenient for miniaturization and lightness of harvesting equipment. The plant is moved by the material shifting piece and the plant cannot fall off the material shifting piece, thereby ensuring the front-to-back alignment effect.

[0017] The method for straightening the rod-shaped plants front and back of the present invention adopts a new straightening method, which straightens the unharvested rod-shaped plants in the front and back directions in sequence by pushing the plants upward from the vicinity of the roots. The straightened plants are arranged neatly in sequence according to the front and back sequence of their roots and are in a vertical state, so as to be ready for subsequent operations.

[0023] The rod-shaped plant front-to-back positioning device of the present invention comprises two rod-shaped plant front-to-back positioning mechanisms, and the two rod-shaped plant front-to-back positioning mechanisms work together to achieve the front-to-back positioning of the rod-shaped plant.

[0024] like Figure 1~Figure 4 As shown, the rod-shaped plant front and rear alignment mechanism includes a frame 1 (only a portion of the frame 1 is drawn in the figure), and a first transmission wheel 2 and a second transmission wheel 3 are arranged on the frame 1, the first transmission wheel 2 is located above the second transmission wheel 3, the first transmission wheel 2 and the second transmission wheel 3 are located in the same plane, the plane is inclined at a certain angle in the front and rear direction, and the second transmission wheel 3 is located behind the first transmission wheel 2, and at the same time, the first transmission wheel 2 and the second transmission wheel 3 are aligned left and right in the front and rear direction, and flexible transmission members 4 are arranged on the first transmission wheel 2 and the second transmission wheel 3, and material-pickup members 6 are arranged on the flexible transmission member 4 at intervals.

[0025] In this way, when the transmission wheel rotates, the material-push member 6 passes through the second transmission wheel 3 and enters the inner side of the front-rear alignment mechanism of the rod-shaped plant. On the inner side of the front-rear alignment mechanism, the material-push member 6 moves upward from the bottom and moves backward at the same time. The upward movement component of the material-push member 6 can push the plant upward, so that it gradually becomes vertical in the front-rear direction. The backward movement component of the material-push member 6 and the forward movement speed of the entire device cancel each other out. Relative to the plant being straightened, the lever only moves upward, and does not move relative to the plant in the front-rear direction.

[0026] Among them, the material shifting member 6 includes a material shifting rod 6-2, which is directly arranged on the flexible transmission member 4, or is arranged on the flexible transmission member 4 through a material shifting block 6-1. The material shifting rod 6-2 extends to the outside of the flexible transmission member 4, and the material shifting rod 6-2 is parallel to the plane where the flexible transmission member 4 is located, and the material shifting rod 6-2 is perpendicular to the flexible transmission member 4.

[0027] The material-digging pieces 6 are evenly arranged along the flexible transmission piece 4, and the distance between two adjacent material-digging pieces 6 in the front-back direction can accommodate one rod-shaped plant. A plurality of material-digging pieces 6 form a plurality of gaps on the flexible transmission piece 4, the gaps are of the same size and are used to accommodate the rod-shaped plants. The rod-shaped plants enter the gaps in turn and are adjusted by the material-digging pieces 6. Each gap accommodates one rod-shaped plant, so that the plants are arranged in turn while being adjusted.

[0028] One side (inner side) of the rod-shaped plant front-to-back alignment mechanism is the working side, and the other side (outer side) is the non-working side. When the material shifting rod 6-2 moves to the working side, the material shifting rod 6-2 moves upward along the flexible transmission member 4 to align the plant. After the material shifting rod 6-2 completes an alignment operation, it moves to the non-working side. Since the non-working side is located on the other side, the plant moving forward and backward relative to the rod-shaped plant front-to-back alignment mechanism will not be interfered with by the material shifting rod 6-2 on this side.

[0029] Generally, the second transmission wheel 3 is set as a driving wheel, and the rotation of the second transmission wheel 3 is driven by a driving device.

[0030] Generally, the first transmission wheel 2 and the second transmission wheel 3 are sprocket wheels, and the flexible transmission member 4 is a chain. The transmission wheel and the flexible transmission member can also be a synchronous pulley and a synchronous belt, or a pulley and a belt, etc. Since the synchronization of the transmission needs to be ensured, a sprocket chain structure or a synchronous pulley and a synchronous belt structure is preferred. At the same time, in order to facilitate the installation of the material-displacing member, the sprocket and chain structure is optimally selected. The material-displacing member can be directly welded and fixed on the chain link of the chain. The connection and fixing method is simple and will not affect the normal operation of the chain.

[0031] In addition, the front and rear positioning mechanism of the rod-shaped plant also includes a corner wheel 5, which is located on the outside of the second transmission wheel 3. The flexible transmission member 4 bypasses the corner wheel 5. The distance between the corner wheel 5 and the second transmission wheel 3 is used for the passage of components such as the transmission shaft of the frame 1 to prevent interference with the flexible transmission member 4.

[0032] The rod-shaped plant front-to-back positioning device comprises two rod-shaped plant front-to-back positioning mechanisms which are arranged symmetrically on the left and right, and a passage for the rod-shaped plant to pass through is provided between the two rod-shaped plant front-to-back positioning mechanisms.

[0033] The material shifting pieces 6 on the two symmetrical rod-shaped plant front and back positioning mechanisms correspond to each other one by one, and the two corresponding material shifting pieces 6 simultaneously position the plants. As long as the rod-shaped plant enters the channel between the two rod-shaped plant front and back positioning mechanisms, it will be straightened front and back by the material shifting pieces 6.

[0034] There is a gap between the ends of the material-moving rods 6-2 on both sides of the correct channel, and the gap is smaller than the diameter of the rod-shaped plant, and the ends of the material-moving rods 6-2 are smooth arc-shaped. When the material-moving rods 6-2 enter the correct channel from below, if the plant is just located between the material-moving rods 6-2 on both sides, after the ends of the two material-moving rods 6-2 gradually approach and contact the surface of the plant, the plant will automatically slide into the gap in front of or behind the material-moving rods 6-2, and will not be sandwiched between the left and right material-moving rods 6-2.

[0035] The present invention also discloses a method for front-to-back alignment of rod-shaped plants, which is implemented based on the aforementioned front-to-back alignment device for rod-shaped plants, so that the front-to-back alignment device for rod-shaped plants moves forward as a whole along a row of plants, and the first transmission wheel 2 or the second transmission wheel 3 drives the material-push piece 6 to move cyclically, and the outer material-push piece 6 enters the alignment channel from below the front-to-back alignment mechanism in turn, and the horizontal component speed of the material-push piece 6 moving backward is made to be the same as the speed of the overall forward movement of the device; the plant passes through the alignment channel between the two front-to-back alignment mechanisms, and the plant is aligned in turn by the material-push pieces 6 on both sides.

[0036] For a plant that is tilted backward, the material-pushing member 6 located at the rear of the plant gradually straightens the plant forward around its root until one of the material-pushing members enters the front of the plant, and the plant is restricted to a vertical state by the front and rear material-pushing members 6 .

[0037] For a plant that is tilted forward, when a material-pushing member 6 enters in front of the plant, the material-pushing member straightens the plant backward around its root to a vertical state.

[0038] The front and rear positioning device for rod-shaped plants of the present invention realizes the front and rear positioning of plants through the transmission wheel structure of the flexible transmission member 4 and the material-shifting member 6. When working, the front and rear positioning device for rod-shaped plants moves forward as a whole with the harvester, so that the rod-shaped plants gradually enter the channel between the two front and rear positioning mechanisms for rod-shaped plants. The material-shifting member 6 located on the inner side of the flexible transmission member 4 moves upward from the bottom. When the plant tilted forward or backward encounters the material-shifting member 6, the material-shifting member 6 shifts the plant so that it gradually becomes vertical.

[0039] Since the material-pickup member 6 moves from the outside of the straightening mechanism from the bottom to the inside of the straightening mechanism, for the plant tilted forward, the material-pickup member 6 is inserted from the front of the plant near the root, and then the material-pickup member 6 gradually moves upward along the flexible transmission member 4, thereby straightening the plant backward; and for the plant tilted backward, there are continuous material-pickup members 6 entering the rear of the plant and the material-pickup member 6 gradually moves upward along the flexible transmission member 4, and the upward-moving material-pickup member 6 continuously pushes the plant forward until a material-pickup member 6 is inserted from the front of the plant near the root, at which time the position of the plant is jointly restricted by the front and rear two toggle members 6, and the plant is in a vertical state at this time.

[0040] The front and rear positioning device for the rod-shaped plants moves forward at a certain speed with the harvester. Through the distribution of power, the speed at which the material-moving member 6 moves backward is equal to the speed at which the harvester moves forward. Therefore, for the rod-shaped plants, the entire positioning process is equivalent to the material-moving rod 6-2 moving vertically upward from below them. When the plant itself is in a vertical state, the material-moving rod 6-2 will not move the plant. When the plant is tilted in the front and rear direction, the material-moving rod 6-2 will move the plant to straighten it.

[0041] Since the material-moving rod 6 starts the straightening operation from the position close to the root of the plant, after the arrangement of the present invention, the rod-shaped plants are arranged according to the front and rear positions of their roots. After straightening, the rod-shaped plants are in a vertical state and will not cross front and back.

[0042] Since the material-shifting members 6 are evenly spaced along the flexible transmission member 4, different plants can be aligned front and back in turn, and adjacent plants can be separated at intervals. The separated plants do not affect each other, and the aligned front and back plants can be conveniently processed later.

[0043] The front and rear alignment device for rod-shaped plants of the present invention is very small in size and weight and occupies a small space, which is beneficial to the miniaturization and lightweight of the harvester. The plant will not fall off the material shifting piece 6 by shifting the plant, thereby ensuring the front and rear alignment effect and being able to quickly straighten the plant. While straightening, the plant can be arranged according to the arrangement order of its roots. The rod-shaped plants straightened by the front and rear alignment device for rod-shaped plants of the present invention are arranged in sequence and in a vertical state, which is beneficial to subsequent further processing.

[0044] The invention is suitable for harvesting pole-shaped plants, and is particularly suitable for front and rear straightening operations of sugarcane during harvesting.
