[0034] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "coupled to" another element, "over" another element, or "covering" another element, it can be directly "on" the other element, "connected to" the other element, "coupled to" the other element, "over" the other element, or "covering" the other element, or there can be one or more other elements intervening between them. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly over" another element, or "directly covering" another element, there can be no other elements intervening between them.

[0035] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0036] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or parts, these components, elements, regions, layers, or parts are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or part from another. Thus, a first component, element, region, layer, or part as referred to in the examples described herein may also be referred to as a second component, element, region, layer, or part without departing from the teachings of the examples.

In addition, although the examples described herein have various configurations, as will be apparent after understanding the disclosure of the present application, other configurations are possible.

[0041] According to a first aspect of the present utility model, a concave plate material uniform distribution guiding mechanism is provided, as Figures 1 to 12 shown. This concave plate material uniform distribution guiding mechanism is used for a harvester. Since this concave plate material uniform distribution guiding mechanism improves the following concave plate body 1, it can solve the effective separation of materials such as materials that accumulate in clusters when the materials, such as grains, enter the separation chamber after being separated by the drum, and at the same time can make the materials evenly distributed, enabling the separation chamber to be utilized evenly. This concave plate material uniform distribution guiding mechanism includes a concave plate body 1, a baffle group 2, a connecting rod assembly 3, and a driving assembly 4.

[0042] In the following description, reference will be made to Figures 1 to 12 specifically describe the detailed structures of the concave plate body 1, the baffle group 2, the connecting rod assembly 3, and the driving assembly 4 of this concave plate material uniform distribution guiding mechanism.

[0043] As Figure 1 and Figure 2 shown, in the embodiment, the concave plate body 1 can be formed as an arc-shaped plate with a certain thickness. The arc-shaped plate corresponds to the drum of the harvester (not shown, the drum is known to those skilled in the art and is used for threshing and separating materials). The arc-shaped plate can be arranged on the side of the drum, and thus can cooperate with the drum to achieve threshing and separation, and at the same time can prevent the passage of longer straws to achieve preliminary separation. The concave plate body 1 is provided with a plurality of through holes 101 for the passage of materials. The through holes 101 can be formed as rectangular holes, and a plurality of vertical rods are arranged inside the rectangular holes for intercepting longer straws. The gaps between the plurality of vertical rods can be used for the passage of grain kernels.

[0044] The baffle group 2 includes a plurality of baffle members 201. The plurality of baffle members 201 are arranged in one-to-one correspondence with the plurality of through ports 101. The baffle member 201 is used to block the through port 101, thereby controlling the passage of cereal straws, grains, etc. Each baffle member 201 is rotatably arranged at the corresponding through port 101. In this way, by adjusting the position of the baffle member 201, that is, adjusting the included angle between the baffle member 201 and the through port 101, the opening degree of the through port 101 can be adjusted, and then the passing amount of the harvested crops can be controlled.

[0045] The connecting rod assembly 3 includes a connecting rod and a transmission rod 303. The connecting rod is connected to the plurality of baffle members 201 and is used to connect the plurality of baffle members 201 together, thereby realizing overall adjustment. The first end of the transmission rod 303 is connected to the connecting rod, and the connecting rod is driven by the transmission rod 303, and then the plurality of baffle members 201 are driven.

[0046] The driving assembly 4 includes a driving part and an intermediate connecting rod 401. The driving part is connected to the intermediate connecting rod 401, and the intermediate connecting rod 401 is connected to the second end of the transmission rod 303. The driving part can drive the intermediate connecting rod 401 to move. The intermediate connecting rod 401 drives the transmission rod 303, and the transmission rod 303 drives the plurality of baffle members 201 to rotate. In addition, the above-mentioned connections can all be hinged. In this way, the user can drive the driving part to adjust the positions of the plurality of baffle members 201 of the baffle group 2, and then control the passing amount of the harvested crops.

[0047] In summary, the concave plate material uniform distribution and guiding mechanism can adjust the opening degree of the through port 101 of the concave plate main body 1 by additionally arranging a baffle group 2 with adjustable position on the concave plate main body 1. In this way, by using different opening degrees of the plurality of through ports 101, the materials accumulated in a group and with a relatively thick thickness can enter the separation chamber slowly in batches through the through ports 101, which can effectively solve the problem that the materials accumulated in a group and with a relatively thick thickness enter the separation chamber through one through port 101 and the separation effect is not good, and can also realize the guiding effect of the materials through the position adjustment of the baffle group 2; in addition, since the opening degree of the through port 101 can be adjusted through the baffle group 2, the user can adjust the opening degree of the through ports 101 at the entrance of the separation chamber and on the side along the rotation direction of the drum to be smaller, for example, 30°, and adjust the opening degree of the through ports 101 at the rear to be larger, for example, 60°, so as to make the material distribution uniform and effectively utilize the entire separation chamber.

[0048] The above-mentioned opening degree can be understood as: as Figures 8 to 11 shown, Figure 8 and Figure 9 are the situations where the opening degree of the through port 101 is the largest. From the side view of Figure 9 , at this time, the included angle between the baffle member 201 and the through port 101 is 90 degrees; Figure 10and Figure 11 When the through - port 101 is in the closed state, as viewed from the side view of Figure 11 , at this time, the included angle between the baffle member 201 and the through - port 101 is 0 degrees. That is to say, by adjusting the position of the baffle member 201, the opening degree of the through - port 101 can be adjusted between 0 degrees and 90 degrees. The larger the opening degree, the greater the throughput of the material; the smaller the opening degree, the smaller the throughput of the material. Thus, the baffle member 201 can be understood to be adjustable between 0 degrees and 90 degrees.

[0049] Furthermore, as Figures 1 to 3 shown, in the embodiment, the baffle member 201 may include a connecting rotating plate 2012 and a baffle body 2011. The connecting rotating plates 2012 are arranged on both sides of the baffle body 2011, that is, connecting rotating plates 2012 are provided at both ends of the baffle body 2011, thereby ensuring the stability of the baffle body 2011 during rotation. The first end of the connecting rotating plate 2012 is hinged to the concave plate main body 1, and the second end of the connecting rotating plate 2012 is hinged to the connecting rod. The connecting rotating plate 2012 can be formed as a structure plate in an approximate concave shape. The two protruding ends of the concave - shaped structure plate are the first end and the second end respectively, and the baffle body 2011 is connected to the side of the protruding end. The connection method can be welding or integral molding. Through - holes are provided at both the first end and the second end of the connecting rotating plate 2012, and the first end and the second end of the connecting rotating plate 2012 can be hinged by the cooperation of fixing bolts or pins and self - locking nuts.

[0050] Furthermore, as Figures 1 to 3 shown, in the embodiment, the baffle group 2 may include a first baffle row and a second baffle row. Both the first baffle row and the second baffle row include a plurality of baffle members 201 arranged at intervals from top to bottom in sequence. Here, from top to bottom can be understood as Figure 1 and Figure 2 from top to bottom in

[0051] Furthermore, as Figures 1 to 3As shown, in the embodiment, the number of the baffle groups 2 is multiple, and the multiple baffle groups 2 are arranged in sequence along the first direction S1. Specifically, in the embodiment, the first direction S1 can be understood as the length direction of the drum, or can also be the direction from the separation chamber inlet and the position on the side along the rotation direction of the drum towards the outlet position at the rear. In the embodiment, a total of three baffle groups 2 are used, and along the first direction S1, they can be respectively the first baffle group 2, the second baffle group 2, and the third baffle group 2.

[0052] Further, as Figures 1 to 3 shown, in the embodiment, the number of the link assemblies 3 and the drive assemblies 4 is both multiple, and the multiple link assemblies 3, the multiple drive assemblies 4 are arranged in one-to-one correspondence with the multiple baffle groups 2. In this way, the three baffle groups 2 in the embodiment can separately adjust the positions of the baffle members 201, and further achieve adaptive adjustment. For example, the opening degree adjusted for the first baffle group 2 is small, while the opening degree of the third baffle group 2 is large, so as to achieve uniform distribution.

[0053] Further, as Figure 1 and Figure 2 shown, in the embodiment, the link assembly 3 can further include a transition rod 304, and the connecting rod can include a first connecting rod 301 and a second connecting rod 302. Since each row of baffle rows includes multiple baffle members 201, and at the same time the concave plate main body 1 is formed in an arc shape, in order to achieve effective transmission, the multiple baffle members 201 located in the upper part are connected together by the first connecting rod 301, the multiple baffle members 201 located in the lower part are connected together by the second connecting rod 302, and the first connecting rod 301 and the second connecting rod 302 are connected together by the transition rod 304, and the transmission rod 303 is connected to the transition rod 304. It should be noted here that the above connections can all be hinged, and the hinge can be achieved by using fixing bolts or pins and cooperating with self-locking nuts.

[0054] Further, as Figures 4 to 7 shown, in the embodiment, the driving part can include a fixing plate 402, a driving plate 403 and a driving member. The driving part is arranged on the harvester through the fixing plate 402, and the setting position can be, for example, on the main frame of the harvester, or it can also be set at a suitable position according to the use requirements, which is not limited here, and the setting method can be, for example, using fixing bolts. The driving plate 403 is arranged on the fixing plate 402, and the setting method can be, for example, using fixing bolts. The driving member is rotatably connected to the driving plate 403, and the driving member is connected to the intermediate link 401. The driving member can rotate on the driving plate 403, and then drive the intermediate link 401, so that the intermediate link 401 changes its position, as Figures 4 to 6As shown, the intermediate connecting rod 401 can move up and down driven by the driving member. When the intermediate connecting rod 401 moves up and down, it can drive the transmission rod 303, and then drive the baffle member 201.

[0055] In the solution of this application, the driving part can include four embodiments, for example Figure 4 the tooth moving type in Figure 5 the track moving type in Figure 6 the moving type of the card hole 409 in Figure 7 and the electric drive type in

[0056] Specifically, as Figure 4 shown, in the first embodiment of the driving part, a rotating shaft for rotation is arranged in the middle of the driving plate 403, and the rotating shaft can be a fixed nut. A moving tooth 405 is arranged along the outer periphery of the driving plate 403, and the moving tooth 405 can be used for the assistance and positioning of rotation. The driving member can include a handle 404 and a fixed tooth 406 arranged on the handle 404, and the fixed tooth 406 meshes with the moving tooth 405. The first embodiment of the driving part is a manual method. By pulling the handle 404, the fixed tooth 406 meshes with the moving tooth 405 and changes its position, and then the intermediate connecting rod 401 connected to the handle 404 changes its position. The handle 404 can be formed as a plate member with a bend, and the bend is rotationally connected to the rotating shaft of the driving plate 403.

[0057] As Figure 5 shown, in the second embodiment of the driving part, a rotating shaft for rotation is also arranged in the middle of the driving plate 403, and the rotating shaft can be in the form of a cooperation of a fixed bolt and a nut. The driving plate 403 is provided with a moving track 407, and the moving track 407 can be formed as an arc and matches the outer edge of the driving plate 403. The driving member includes a handle 404 and a moving member 408. The moving member 408 passes through the handle 404 and is arranged in the moving track 407. The moving member 408 can be a butterfly locking nut and can achieve locking and loosening. The handle 404 can slide along the moving track 407 and is locked at a certain position through the moving member 408.

[0058] In summary, the first and second embodiments of the driving part are both manually steplessly adjustable. The user needs to manually adjust the position of the handle 404. In addition, an adjustment scale (not shown) can be set on the driving plate 403 to facilitate the user to intuitively see the adjustment state of the baffle member 201 at this time. For example, if the user wants to adjust the opening degree of the through port 101 to the maximum, the handle 404 can be screwed to the 90-degree position of the adjustment scale on the driving plate 403.

[0059] As Figure 6As shown, in the third embodiment of the driving part, a rotating shaft for rotation is also provided in the middle of the driving plate 403, and the rotating shaft can be a fixing nut. The driving plate 403 is provided with clamping holes 409, and the number of the clamping holes 409 can be multiple, and the multiple clamping holes 409 are evenly distributed along the outer periphery of the driving plate 403. The driving member includes a handle 404 and a moving member 408. The moving member 408 passes through the handle 404 and is arranged in the clamping hole 409. The moving member 408 can be a butterfly locking nut and can realize locking and loosening. The handle 404 can change the position of the intermediate connecting rod 401 by clamping the moving member 408 in different clamping holes 409. The third embodiment of the driving part is a manual multi-stage adjustment method, and the position of the baffle member 201 is adjusted through different clamping holes 409. The set positions of the clamping holes 409 can respectively represent 0 degrees, 30 degrees, 60 degrees and 90 degrees, and the user can clamp the moving member 408 in the clamping holes 409 at different positions according to needs.

[0060] As Figure 7 shown, in the fourth embodiment of the driving part, the driving part can further include an induction control module for monitoring the material state. The induction control module can include an induction unit 501 and a control unit 502. The induction unit 501 can be used to monitor key elements such as the material density, flow rate, and material humidity weight in the equipment flow channel in real time. Through the detection of these states, the user can be assisted to adjust the position of the baffle group 2 to avoid the problem that the material accumulates into a mass and cannot be effectively separated or is unevenly distributed. The induction unit 501 can include a weight detector, a humidity detector, a flowmeter, etc. These components are all common components, and their principles and structures are known to those skilled in the art. In addition, the induction unit 501 is also a common component for those skilled in the art of harvesters and will not be elaborated here as long as it can realize monitoring. The control unit 502 can be a component of existing technologies such as a PLC controller or an electric control cabinet, and can be used to receive data from the induction unit 501 and calculate the optimal opening degree of the baffle group 2 through existing formulas, and adjust it through the driving member. The driving member can include a driving part 503. The connecting end of the driving part 503 is connected to the induction control module, and the output end of the driving part 503 is connected to the intermediate connecting rod 401. The driving part 503 can, for example, drive a lead screw by a driving motor to realize linear motion output, and then drive the intermediate connecting rod 401, or the driving part 503 can be a telescopic cylinder, and the intermediate connecting rod 401 is driven to move through the telescopic rod. The fourth embodiment of the driving part is an automatic adjustment. It is necessary to use the induction control module and the electric drive type driving part to realize automatic control and adjustment. In this way, the problem that the material cannot be effectively separated and affects the threshing effect and is unevenly distributed can be solved without manual adjustment by the user.

[0061] Preferably, as Figure 12 shown, Figure 12For a brief material movement trajectory diagram, the usage process of the concave plate material uniform distribution guiding mechanism is as follows: The concave plate main body 1 is installed on the side of the drum. When the drum rotates (the drum rotation direction is S2), the material passes through the through port 101 of the concave plate main body 1 (the material movement direction is S3). During this process, the user can drive the connecting rod assembly 3 to move through the driving assembly 4, and the connecting rod assembly 3 drives the baffle member 201 of the baffle group 2 to rotate, so that an angle is formed between the baffle member 201 and the through port 101. This angle is between 0 degrees and 90 degrees. The larger the angle, the larger the opening degree of the through port 101, and the more material passes through. The smaller the angle, the smaller the opening degree of the through port 101, and the less material passes through. In this way, first, by adjusting the opening degree of the through port 101, it is possible to prevent the agglomerated material from directly passing through the through port 101 and entering the separation chamber, resulting in ineffective threshing and separation and affecting the threshing effect. The through port 101 with a certain opening degree can assist in the separation of the agglomerated material. At the same time, since the baffle member 201 has a certain angle, it can play a guiding role and can gather grains or straws, etc., improving the subsequent cleaning effect. Second, the user can adjust the opening degree of the through port 101 at the position of the separation chamber entrance and along the side of the drum rotation direction to reduce the amount of material passing through there, and adjust the opening degree of the through port 101 at the rear outlet position to be larger, preventing a large amount of material from passing through the through port 101 at the front and entering the cleaning and separation chamber, while there is no material passing through at the rear, resulting in uneven utilization of the entire separation chamber front and back, and ensuring the uniform distribution of the material.

[0062] The concave plate material uniform distribution guiding mechanism can separately adjust the baffle members of the baffle group according to the properties of the material and the actual usage process, and then adjust the opening degree of the through port of the concave plate main body to adapt to the harvesting situation of the material, so as to control the discharge amount of the material, thereby improving the threshing effect and enhancing the effective utilization rate of the separation device. At the same time, the baffle group can play a role in guiding and uniformly distributing the material, thereby enhancing the utilization rate of the separation chamber and improving the cleaning effect.

[0063] In addition, according to the second aspect of the present invention, a harvester is provided, and the harvester includes the concave plate material uniform distribution guiding mechanism as described above. By installing the concave plate material uniform distribution guiding mechanism, the harvester can improve the cleaning effect.

[0064] Preferably, the harvester can include multiple concave plate material uniform distribution guiding mechanisms, that is, it can include multiple concave plate main bodies 1. The user can select an appropriate number of concave plate main bodies 1 according to the drum length and usage requirements to meet the cleaning requirements, thereby improving the cleaning effect.

[0065] Finally, it should be noted that the above-described embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting it. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that any person skilled in the technical field can still modify the technical solutions described in the foregoing embodiments, or can easily think of changes, or perform equivalent replacements for some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
