Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesters, in particular to a novel non-row corn hoe-pulling and conveying mechanism, a cutting platform and a corn harvester. Background Art

[0002] At present, major domestic manufacturers have developed plate-type non-row harvesting platforms. In order to reduce the transmission load, most manufacturers use two-side transmission (i.e. two sets of gear boxes on the left and two sets of gear boxes on the right). In order to achieve non-row harvesting of the harvesting platform, the shifting fingers of the rice chain between the groups are staggered and have a large overlap. However, when the transmission on both sides is inconsistent, it is very easy to cause interference between the two sets of rice chain fingers in the middle, resulting in increased failures and user complaints.

[0003] In order to solve the above problems, the prior art provides the following solutions:

[0004] Solution 1: Change the finger on one side to a short finger and add a triangular transition plate in the middle. The harvesting effect will be worse, which will not satisfy the users.

[0005] Solution 2: Increasing the distance between the adjacent tension wheels on the front side of the middle group of ear picking devices will result in poor harvesting effect for the rows, which is not acceptable to users. Utility Model Content

[0006] The utility model provides a novel non-row corn hoe conveying mechanism, a cutting platform and a corn harvester, aiming to solve the problems in the prior art.

[0007] The technical solution of the utility model to solve the above technical problems is as follows:

[0008] A novel non-linear corn straw conveying mechanism comprises a plurality of straw conveying units, which are evenly spaced and arranged side by side; each of the straw conveying units comprises two straw chain assemblies, and the two straw chain assemblies of the same straw conveying unit are relatively arranged and can rotate towards each other; each straw chain assembly is provided with a plurality of shifting fingers evenly spaced along its own rotation direction, the opposite ends of the plurality of shifting fingers on the two straw chain assemblies close to each other in two adjacent conveying units are in the same plane, and the opposite ends of the plurality of shifting fingers on the two straw chain assemblies are staggered up and down.

[0009] The beneficial effects of the utility model are as follows: during the reeling process, when two reeling chain assemblies close to each other in two adjacent conveying units are synchronously operated, multiple fingers of the reeling chain assemblies on the two reeling chains are staggeredly distributed, and the corresponding two fingers will not collide;

[0010] When two adjacent reed chain assemblies in two adjacent conveying units run asynchronously, multiple fingers of the two reed chain assemblies can be rotated to be relatively distributed, or one end can be staggered up and down by utilizing the particularity of its own structure, and the corresponding two fingers will not collide, thereby avoiding damage to the reed chain.

[0011] The utility model has the advantages of simple structure and reasonable design, and the use of special-shaped shifting fingers can effectively avoid the problem of shifting fingers fighting with each other, avoid damage to the shifting chain, extend the service life of the shifting chain, and reduce the cost.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, in the two mutually close-to-neighboring conveying units of the two reel chain assemblies, the upper side of the other end of the plurality of reel fingers on one of the reel chain assemblies is recessed downward to form a lower step, and the lower side of the other end of the plurality of reel fingers on the other reel chain assembly is recessed upward to form an upper step, and when the corresponding reel fingers of the two reel chain assemblies are rotated to the same position, the step surface of the upper step is in contact with the step surface of the lower step.

[0014] The beneficial effect of adopting the above further scheme is simple structure and reasonable design. The particularity of the shapes of multiple fingers in two mutually adjacent reed chain assemblies of two adjacent conveying units is utilized so that the corresponding two fingers can be staggered up and down when rotating to relative to each other, avoiding damage to the reed chain.

[0015] Furthermore, the step surface of the upper step and the step surface of the lower step are inclined surfaces in opposite directions.

[0016] The beneficial effect of adopting the above further scheme is simple structure and reasonable design. The step surface of the upper step and the step surface of the lower step are set as inclined surfaces in opposite directions, which can make the two fingers staggered up and down to avoid collision when they are rotated to relative separation, and ensure the stability of the operation of the two reed chain components.

[0017] Furthermore, a plurality of the fingers are bent teeth.

[0018] The beneficial effect of adopting the above further scheme is that the bending teeth are formed by bending the plate-like structure, which can not only ensure the feeding efficiency of corn, but also save materials and reduce costs.

[0019] Furthermore, each of the plurality of fingers has a structure with one end being thick and the other end being thin.

[0020] The beneficial effects of adopting the above further scheme are simple structure and reasonable design, which can not only ensure the feeding efficiency of corn, but also save materials and reduce costs.

[0021] Furthermore, the plurality of shifting fingers are arc-shaped teeth respectively, and the concave sides of the plurality of shifting fingers on the sides of the two adjacent reed chain assemblies in the two adjacent conveying units are oriented toward the discharge end of the corresponding reed chain assembly.

[0022] The beneficial effect of adopting the above further scheme is that the shapes of the multiple fingers are reasonably designed, which can not only ensure the feeding of corn, but also reduce the friction between the fingers and the corn stalks, thereby reducing the wear of the fingers.

[0023] Furthermore, each of the plowing chain assemblies comprises a plowing chain and a driving member, wherein the plowing chain is evenly and fixedly mounted with a plurality of plowing fingers along its rotation direction; and the driving member is in transmission connection with the plowing chain for driving the plowing chain to rotate.

[0024] The beneficial effect of adopting the above further scheme is that during the harvesting process, the two driving members in the same reed-pulling and conveying unit respectively drive the two reed-pulling chains to rotate towards each other for feeding, which makes feeding convenient and efficient.

[0025] Furthermore, the feeding ends of the two reel-pushing chains of one reel-pushing conveying unit are far away from each other, and the discharging ends thereof are close to each other.

[0026] The beneficial effects of adopting the above further scheme are simple structure, convenient distribution of the two reed-pulling chains, and smooth feeding of corn.

[0027] The utility model also relates to a harvesting platform, comprising the novel non-row corn hoe conveying mechanism as described above.

[0028] The beneficial effect of adopting the above further scheme is that the utility model also provides a cutting table with a simple structure and reasonable design. The use of special-shaped fingers can effectively avoid the problem of finger fighting, avoid damage to the straw chain, extend its service life and reduce costs.

[0029] The utility model also relates to a corn harvester, comprising the cutting platform as described above.

[0030] The beneficial effect of adopting the above-mentioned further scheme is that the utility model also provides a corn harvester with a simple structure and reasonable design. The use of special-shaped shift fingers can effectively avoid the problem of shift finger fighting, avoid damage to the straw chain, extend its service life and reduce costs.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] Example 1

[0044] like Figures 1 to 5 As shown, this embodiment provides a novel non-linear corn straw conveying mechanism, comprising a plurality of straw conveying units, which are evenly spaced and arranged side by side; each of the straw conveying units comprises two straw chain assemblies, and the two straw chain assemblies of the same straw conveying unit are relatively distributed and can rotate toward each other; each of the straw chain assemblies is respectively and evenly spaced along its own rotation direction. A plurality of fingers 1 are respectively installed on the straw chain assembly at even intervals, and the opposite ends of the plurality of fingers 1 on the two straw chain assemblies close to each other in two adjacent conveying units are in the same plane, and the other opposite ends of the plurality of fingers 1 on the two straw chain assemblies are staggered up and down.

[0045] During the reeling process, when two reeling chain assemblies close to each other in two adjacent conveying units are operated synchronously, the multiple fingers 1 of the reeling chain assemblies on the two reeling chains are staggered, and the corresponding two fingers 1 will not collide;

[0046] When two reel chain assemblies close to each other in two adjacent conveying units run asynchronously, the multiple fingers 1 of the reel chain assemblies on the two reel chain assemblies can be rotated to be relatively distributed or one end can be staggered up and down by utilizing the particularity of their own structure, and the corresponding two fingers 1 will not collide, thereby avoiding damage to the reel chain.

[0047] Preferably, the present embodiment further comprises a frame, and a plurality of reel conveying units are installed side by side on the frame.

[0048] The present embodiment has a simple structure and a reasonable design. The use of special-shaped shifting fingers can effectively avoid the problem of the shifting fingers fighting with each other, avoid damage to the reed chain, extend its service life and reduce costs.

[0049] Example 2

[0050] On the basis of Example 1, in this embodiment, in the two mutually adjacent conveying units of the two reed chain assemblies, the upper side of the other end of the multiple fingers 1 on one of the reed chain assemblies is recessed downward to form a lower step 2, and the lower side of the other end of the multiple fingers 1 on the other reed chain assembly is recessed upward to form an upper step 3, and when the corresponding fingers 1 of the two reed chain assemblies are rotated to the same position, the step surface of the upper step 3 is in contact with the step surface of the lower step 2.

[0051] The scheme has a simple structure and a reasonable design. It utilizes the particularity of the shapes of multiple fingers 1 in two mutually adjacent reel chain assemblies of two adjacent conveying units so that the corresponding two fingers 1 can be staggered up and down when rotating to relative to each other, thereby avoiding damage to the reel chain.

[0052] Example 3

[0053] On the basis of Embodiment 2, in this embodiment, the step surface of the upper step 3 and the step surface of the lower step 2 are inclined surfaces in opposite directions.

[0054] The scheme has a simple structure and a reasonable design. The step surface of the upper step 3 and the step surface of the lower step 2 are set as inclined surfaces in opposite directions, which can not only make the two fingers 1 staggered up and down to avoid collision when they are rotated to be relatively separated, but also ensure the stability of the operation of the two reed chain components.

[0055] Example 4

[0056] On the basis of the above embodiments, in this embodiment, a plurality of the fingers 1 are bent teeth.

[0057] The bending teeth are formed by bending a plate-like structure, which can not only ensure the feeding efficiency of corn, but also save materials and reduce costs.

[0058] Alternatively, the plurality of fingers 1 may also adopt teeth with a conical structure.

[0059] Alternatively, the plurality of fingers 1 may be replaced by levers, and in this case, one end of the plurality of levers is a step-shaped structure.

[0060] Example 5

[0061] On the basis of the above embodiments, in this embodiment, the plurality of fingers 1 are respectively in a structure with one end being thick and the other end being thin.

[0062] The scheme has a simple structure and reasonable design, which can not only ensure the feeding efficiency of corn, but also save materials and reduce costs.

[0063] Alternatively, the plurality of fingers 1 may also adopt a structure with the same size at both ends.

[0064] Example 6

[0065] Based on the above embodiments, in this embodiment, the plurality of fingers 1 are arc-shaped teeth, and the concave sides of the plurality of fingers 1 on the sides of the two adjacent reed chain assemblies in the two adjacent conveying units are oriented toward the discharge end of the corresponding reed chain assembly.

[0066] The shapes of the plurality of fingers 1 are reasonably designed, which can not only ensure the feeding of corn, but also reduce the friction between the fingers 1 and the corn stalks, thereby reducing the wear of the fingers.

[0067] Based on the above scheme, the convex sides of multiple fingers are in contact with the corn stalks during feeding.

[0068] In addition, the concave side of the finger 1 refers to a side of the finger 1 that is concave, and the convex side of the finger 1 refers to a side of the finger 1 that is convex.

[0069] Example 7

[0070] On the basis of the above embodiments, in this embodiment, each of the plowing chain assemblies includes a plowing chain 4 and a driving member, and the plowing chain 4 is evenly and fixedly installed with a plurality of plowing fingers 1 along its own rotation direction; the driving member is transmission-connected to the plowing chain 4 for driving the plowing chain 4 to rotate.

[0071] During the harvesting process, the two driving members in the same reed-pulling and conveying unit respectively drive the two reed-pulling chains 4 to rotate in opposite directions for feeding, which makes feeding convenient and efficient.

[0072] Based on the above scheme, both ends of each reed chain 4 are respectively sleeved on the conveying gear, and the two conveying gears are respectively rotatably mounted on the frame; the driving member here is the gear box of the corn harvester, that is, the gear box drives the two power conveying gears in the multiple conveying units to rotate towards each other, so as to drive the two reed chains 4 to rotate, so as to feed the material, and the feeding is convenient. This scheme uses the power of the corn harvester itself to realize operation, saving energy consumption.

[0073] Based on the above scheme, the structure of the gear box is the prior art, and its specific structure and principle will not be described in detail here.

[0074] In addition to the above-mentioned implementation, the two reel chains 4 may also adopt separate driving devices. However, this solution requires additional driving devices to be arranged on the frame, which occupies a large space and increases the cost.

[0075] Example 8

[0076] On the basis of Embodiment 7, in this embodiment, the feeding ends of the two reeling chains 4 of one reeling conveying unit are far away from each other, and the discharging ends thereof are close to each other.

[0077] The scheme has a simple structure, and the two reed-pulling chains 4 are conveniently distributed, which facilitates the smooth feeding of corn.

[0078] Preferably, in this embodiment, the two reed chains 4 are in an overall figure eight shape.

[0079] In addition to the above embodiment, the distances between the two ends of the two reed-pulling chains 4 can be equal, that is, the two reed-pulling chains 4 are distributed in parallel. Comparatively speaking, the reed-pulling effect of this solution is not as good as that of the above solution.

[0080] Example 9

[0081] Based on the above embodiments, Figure 6 As shown, this embodiment also provides a harvesting platform, including the novel non-row corn hoe conveying mechanism described above.

[0082] The present embodiment also provides a harvesting platform, which has a simple structure and a reasonable design. The use of special-shaped fingers can effectively avoid the problem of fingers fighting with each other, avoid damage to the harvesting chain, extend its service life and reduce costs.

[0083] Example 10

[0084] Based on Example 9, this example also provides a corn harvester, including the cutting table as described above.

[0085] The present embodiment provides a corn harvester, which has a simple structure and a reasonable design. The use of special-shaped shift fingers can effectively avoid the problem of the shift fingers fighting with each other, avoid damage to the straw chain, extend its service life, and reduce costs.

[0086] The working principle of the utility model is as follows:

[0087] During the reeling process, when two reeling chain assemblies close to each other in two adjacent conveying units are operated synchronously, the multiple fingers 1 of the reeling chain assemblies on the two reeling chains are staggered, and the corresponding two fingers 1 will not collide;

[0088] When two reel chain assemblies close to each other in two adjacent conveying units run asynchronously, the multiple fingers 1 of the reel chain assemblies on the two reel chain assemblies can be rotated to be relatively distributed or one end can be staggered up and down by utilizing the particularity of their own structure, and the corresponding two fingers 1 will not collide, thereby avoiding damage to the reel chain.

[0089] The utility model has the advantages that the reed chains overlap in the vertical direction (that is, the transmission surfaces of the sprockets of the two reed chains overlap), ensuring that the fingers overlap in the left and right directions (that is, along the length direction of the fingers).

[0090] The utility model can solve the problem of high failure rate of the current non-row harvesting table straw chain. In order to improve the non-row harvesting effect of the plate-type corn harvester, the overlap of adjacent shifting fingers is relatively high. In order to ensure reasonable power distribution, the two middle groups are disconnected. When the transmission is not synchronized, it is very easy for the two middle groups of shifting fingers to fight with each other, causing damage to the straw chain.

[0091] It should be noted that all electronic components involved in the present invention adopt the existing technology, and the above-mentioned components are electrically connected to the controller, and the control circuit between the controller and each component is the existing technology.

[0092] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0093] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
