Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to a grass-clearing support and a semi-feeding combine harvester. Background Technology

[0002] With the continuous improvement of agricultural mechanization, semi-feed combine harvesters are widely used due to their high harvesting efficiency and adaptability. During operation, a semi-feed combine harvester threshes the crop ears through its threshing body, effectively separating the grain from the stalks. The threshed crop stalks are then discharged from the machine through a straw discharge assembly, allowing for efficient grain collection. In existing technologies, to improve operational efficiency and reduce manual intervention, the design of semi-feed combine harvesters typically incorporates automated straw discharge mechanisms to ensure smooth discharge of crop stalks.

[0003] However, in actual operation, when there is a sudden increase in material or other malfunctions, the straw discharge port is prone to blockage. At this time, the operator needs to manually clear the blockage, but because the straw discharge port is relatively narrow, the clearing process is not only time-consuming and laborious, but also inconvenient, affecting the overall work efficiency and the ability to operate continuously.

[0038] Some embodiments of the utility model will be described in detail below in combination with the drawings. In the case of no conflict, the following examples and features in the examples can be combined with each other.

[0039] Example 1

[0040] Referring to Figures 1-5 , the embodiment provides a grass discharging support, comprising:

[0041] Support 1;

[0042] Rotary seat plate 3, support 1 and rotary seat plate 3 are connected through rotary shaft 2, rotary seat plate 3 is used for being fixed on the right side beam of threshing machine body 8, and support 1 can rotate around rotary seat plate 3 through rotary shaft 2;

[0043] The support 6 is fixed on the rear side wall of the threshing machine body 8, and the bracket 1 is connected with the support 6 through the pull plate 5 and the pneumatic strut spring 4, respectively, the pull plate 5 is used to prevent the bracket 1 from rotating around the rotating shaft 2, and plays a role of limiting, positioning or fixing the bracket 1.

[0044] The first seat plate 101 is arranged on the bracket 1, one end of the pneumatic strut spring 4 is connected with the first seat plate 101, and the other end is connected with the support 6, as shown in Figure 1 .

[0045] One end of the pneumatic strut spring 4 is hinged with the first seat plate 101, and the other end is hinged with the support 6.

[0046] Specifically, one end of the pull plate 5 is bolted with the second seat plate 102, and the other end is bolted with the support 6.

[0047] The positional relationship between the first seat plate 101, the second seat plate 102 and the rotating seat plate 3 is that the distance between the second seat plate 102 and the rotating seat plate 3 is greater than the distance between the first seat plate 101 and the rotating seat plate 3, as shown in Figure 2 .

[0048] The straw discharge bracket is a device used in agricultural machinery (such as a semi-feed combine harvester), which mainly functions to help process and discharge the straw of crops during the operation of the machine. Specifically, the straw discharge bracket discharges the threshed straw out of the machine through the straw discharge port 9 after the rice panicles are threshed in the threshing part of the machine.

[0049] In the existing technology, if the straw discharge port 9 is blocked, it is relatively troublesome to clean up because the straw discharge port 9 is narrow in position and needs to be cleaned manually. However, the present invention provides a new solution by designing a straw discharge bracket that can be lifted upward, so that when the straw discharge port 9 is blocked, the blocked straw can be cleaned up more easily.

[0050] In summary, the straw discharge bracket includes the following key components:

[0051] 1. Bracket 1: the main structure of the entire device.

[0052] 2. Rotating shaft 2: the part that allows the bracket 1 to rotate.

[0053] 3. Rotating seat plate 3: the part that fixes the bracket 1 on the machine.

[0054] 4. Pneumatic strut spring 4: provides the force to lift the bracket 1.

[0055] 5. Pull plate 5: used to fix the bracket 1 so that it remains in the normal working position.

[0056] 6. Support 6: another part fixed on the machine, used to connect the bracket 1 and the pull plate 5.

[0057] When it is necessary to clean the blockage, the support 1 can be lifted by removing the pull plate 5 and using the force of the pneumatic strut spring 4, so that the straw discharge assembly is also lifted together, thereby facilitating the cleaning of the blockage. After cleaning is completed, only the pull plate 5 needs to be reinstalled, and the support 1 will automatically return to the original position.

[0058] Such a design not only improves the maintenance efficiency, but also increases the convenience and safety of operation.

[0059] When the straw discharge support is installed: the rotary seat plate 3 of the straw discharge support is fixed on the right side beam of the threshing machine body 8, the support 1 is connected with the rotary seat plate 3 through the rotary shaft 2, and the support 1 can rotate around the rotary shaft 2; the support base 6 of the straw discharge support is fixed on the rear side wall of the threshing machine body 8, the support 1 is connected with the support base 6 through the pull plate 5 and the pneumatic strut spring 4, the pull plate 5 can fix the straw discharge support with the threshing machine body 8 to prevent the straw discharge support from being opened, and the pneumatic strut spring 4 can provide force for opening the straw discharge support, and in the case where the pull plate 5 is not fixed, the straw discharge support can be popped open; the straw discharge assembly is fixed below the straw discharge support and moves together with the straw discharge support, and the main function of the straw discharge support is to open or close with the straw discharge assembly, thereby facilitating the cleaning of the stems at the straw discharge port 9 when the straw is blocked;

[0060] When the straw discharge port 9 of the combine harvester is blocked, the straw discharge support can be opened (lifted up) to drive the straw discharge assembly to be lifted up together, specifically: first, remove the pull plate 5 to take down the pull rod, at this time, there is no connection of the pull plate 5, the support 1 is no longer fixed, under the action of the elastic force of the pneumatic strut spring 4, the support 1 rotates around the rotary shaft 2, realizes the overall lifting of the straw discharge support and the straw discharge assembly, and then the blockage can be quickly cleaned, the maintenance efficiency when the straw is blocked is improved, the convenience of maintenance is increased, and the smoothness of straw discharge is improved.

[0061] Embodiment 2

[0062] The embodiment provides a straw discharge support, which is different from the technical scheme of embodiment 1 in that: in the embodiment, one end of the pneumatic strut spring 4 is connected with the first seat plate 101 through a first guide rail sliding block assembly, and the other end is connected with the support base 6 through a second guide rail sliding block assembly (this is an expansion scheme, which is not shown in the drawings).

[0063] The first guide rail sliding block assembly can adopt a linear guide rail sliding block assembly or an arc-shaped guide rail sliding block assembly (the structures of the linear guide rail sliding block assembly or the arc-shaped guide rail sliding block assembly are prior art, and will not be described here), one end of the pneumatic strut spring 4 is fixedly connected with the sliding block of the first guide rail sliding block assembly, and the first seat plate 101 is fixedly connected with the guide rail of the first guide rail sliding block assembly, or one end of the pneumatic strut spring 4 is fixedly connected with the guide rail of the first guide rail sliding block assembly, and the first seat plate 101 is fixedly connected with the sliding block of the first guide rail sliding block assembly.

[0064] The second guide rail slider assembly can also be a linear guide rail slider assembly or an arc-shaped guide rail slider assembly. In this case, the other end of the pneumatic support rod spring 4 is fixedly connected with the slider of the second guide rail slider assembly, and the support 6 is fixedly connected with the guide rail of the second guide rail slider assembly. Alternatively, the other end of the pneumatic support rod spring 4 is fixedly connected with the guide rail of the second guide rail slider assembly, and the support 6 is fixedly connected with the slider of the second guide rail slider assembly.

[0065] In this embodiment, the two ends of the pneumatic support rod spring 4 are connected with the first seat plate 101 and the support 6 through the guide rail slider assemblies, respectively. This can also achieve the overturning of the straw discharge support, but the positions of the guide rail slider assemblies at the two ends of the pneumatic support rod spring 4 need to be reasonably designed.

[0066] Embodiment 3

[0067] A semi-feed combined harvester includes the straw discharge support (refer to Figures 1-4 ), and further includes a threshing machine body 8, a straw discharge assembly, and a cylinder cover, as Figure 5 shown.

[0068] Regarding the threshing machine body 8, specifically: the rotary seat plate 3 is fixedly connected with the right side beam of the threshing machine body 8, and the support 6 is fixedly connected with the rear side wall of the threshing machine body 8.

[0069] The threshing machine body 8 is one of the core parts of the semi-feed combined harvester, and its main function is to perform threshing processing on the harvested crops (such as rice, wheat, etc.). The specific functions and effects of the threshing machine body 8 are as follows:

[0070] Functions and effects of the threshing machine body 8:

[0071] 1. Threshing processing: The main function of the threshing machine body 8 is to perform threshing processing on the harvested crops. It separates the grains from the stems through specific mechanisms (such as a cylinder and a concave plate), which rub and squeeze the stems.

[0072] 2. Separation mechanism: The threshing machine body 8 usually contains a series of separation mechanisms, such as a concave plate, a fan, and a screen, etc. These mechanisms work together to separate the threshed grains from the stems and impurities, and collect the grains.

[0073] In this scheme, the threshing machine body 8 cooperates with other components such as the straw discharge assembly and the straw discharge support to achieve an efficient crop harvesting process. Specifically:

[0074] 1. Cooperation with the straw discharge support: The threshing machine body 8 manages the discharge of the threshed straw through the straw discharge support. When the straw discharge port 9 is blocked, the straw discharge support can be lifted and reset to facilitate the cleaning of the blocked straw.

[0075] 2. Coordination with the straw discharge assembly: The threshing machine body 8 discharges the threshed straw through the straw discharge assembly. Reasonable design of the straw discharge assembly can reduce the occurrence of blockage problems and improve cleaning efficiency.

[0076] 3. Coordination with the cylinder cover: The cylinder cover plays a protective and sealing role during operation. When cleaning the blockage, opening the cylinder cover can make it easier to operate the straw discharge support, improving cleaning efficiency.

[0077] Regarding the straw discharge assembly, specifically: the straw discharge assembly is fixed below the support 1 and moves with the support 1, the support 1 can drive the straw discharge assembly to open or close to clean the stems at the straw discharge port 9 when the straw is blocked.

[0078] The straw discharge assembly is an important part of the semi-feed combined harvester, responsible for discharging the threshed crop straw from the machine. The specific functions and effects of the straw discharge assembly are as follows:

[0079] Functions and effects of the straw discharge assembly:

[0080] 1. Straw discharge: The main function of the straw discharge assembly is to discharge the remaining straw after threshing from the machine. This is an essential part of the harvesting process, ensuring that the machine can work continuously and efficiently.

[0081] 2. Structural design: The straw discharge assembly usually includes multiple components, such as conveyors, guide rails, and guards, which work together to ensure smooth discharge of straw from the machine.

[0082] 3. Position fixation: The straw discharge assembly is generally fixed below the straw discharge support and moves with the straw discharge support. This design allows the straw discharge assembly to be lifted together when needed, making it easier to clean blockages.

[0083] 4. Anti-blocking function: The design of the straw discharge assembly also needs to consider the anti-blocking function to avoid blockage problems when the amount of straw is large. Reasonable structural design and appropriate material selection can effectively reduce the probability of blockage.

[0084] In the technical solution of this application, the straw discharge assembly is lifted and reset by the straw discharge support, solving the problem of blockage of the straw discharge port 9. The specific steps are as follows:

[0085] 1. When the straw discharge port 9 is blocked, the fixing device of the straw discharge support can be removed (remove the pull plate 5).

[0086] 2. The straw discharge support is lifted upward under the action of the pneumatic support rod spring 4, and the straw discharge assembly is also lifted, making it easier to clean the blocked straw.

[0087] 3. After cleaning, re-fix the straw discharge support and close the cylinder cover, the straw discharge support will automatically reset.

[0088] The following detailed description:

[0089] 1. Normal working state: The straw discharge assembly is fixed below the straw discharge support, and the straw is discharged through the straw discharge port 9.

[0090] The straw discharge support is connected with the threshing machine body 8 through the rotary shaft 2, and can rotate around the rotary shaft 2.

[0091] The support 1 is connected with the support 6 through the pull plate 5 and the pneumatic support rod spring 4, and maintains a fixed closed state.

[0092] 2. Clear the blocked state:

[0093] Remove the pull plate 5, and the straw discharge support is lifted under the action of the pneumatic support rod spring 4.

[0094] The straw discharge assembly is lifted, making it easy to clean the blocked straw.

[0095] 3. Reset state:

[0096] After cleaning, re-fix the straw discharge support and close the cylinder cover.

[0097] The straw discharge support and the straw discharge assembly are automatically reset to the initial position.

[0098] Through the above design, the straw discharge assembly plays an important role in improving maintenance efficiency and operation convenience, so that the semi-feed combined harvester can quickly solve the problem when the straw blockage problem occurs.

[0099] It also includes a cylinder cover, which is fixed above the straw discharge support and can be opened or closed with the straw discharge support.

[0100] The cylinder cover is an important part of the semi-feed combined harvester, mainly used to cover and protect the threshing cylinder inside the machine. Here are the specific functions and effects of the cylinder cover:

[0101] Functions and effects of the cylinder cover:

[0102] 1. Protect the threshing cylinder: One of the main functions of the cylinder cover is to protect the internal threshing cylinder from external environmental influences such as dust, debris, etc. It ensures that the internal components of the machine are not disturbed by external interference during operation.

[0103] 2. Sealing effect: The cylinder cover also has a sealing effect, ensuring that the threshing process inside the machine is carried out in a relatively closed environment, improving threshing efficiency and reducing the spread of noise and dust.

[0104] 3. Easy to operate: the cylinder cover is usually openable and closable, which is convenient for operators to check, maintain and clean. For example, when the straw discharge port 9 is blocked, the opening of the cylinder cover can assist the lifting and resetting of the straw discharge support.

[0105] 4. Safety protection: the cylinder cover can also serve as a safety measure to prevent operators from accidentally contacting the high-speed rotating threshing cylinder when the machine is working, ensuring safe operation.

[0106] In the scheme of the present application, the cylinder cover plays an important role. When it is necessary to clean the straw discharge port 9 blocked by straw, the following steps can be taken:

[0107] 1. Open the cylinder cover.

[0108] 2. Release the fixing device of the straw discharge support (remove the pull plate 5).

[0109] 3. The straw discharge support is lifted under the action of the pneumatic support rod spring 4, thereby lifting the straw discharge assembly together, facilitating the cleaning of the blocked straw.

[0110] 4. After cleaning, reset the straw discharge support.

[0111] 5. Close the cylinder cover, and at this time the straw discharge support will be automatically reset and re-fixed with the threshing machine body 8.

[0112] When the straw discharge support is installed:

[0113] (1) The rotary seat plate 3 of the straw discharge support is fixed on the right side beam of the threshing machine body 8, the support 1 is connected with the rotary seat plate 3 through the rotary shaft 2, and the support 1 can rotate around the rotary shaft 2;

[0114] (2) The support 6 of the straw discharge support is fixed on the rear side wall of the threshing machine body 8, the support 1 is connected with the support 6 through the pull plate 5 and the pneumatic support rod spring 4, the pull plate 5 can fix the straw discharge support with the threshing machine body 8 to prevent the straw discharge support from opening, and the pneumatic support rod spring 4 can provide force for the opening of the straw discharge support, and in the case where the pull plate 5 is not fixed, the straw discharge support can be popped open;

[0115] (3) The straw discharge assembly is fixed below the straw discharge support and moves together with the straw discharge support, and the main function of the straw discharge support is to open or close with the straw discharge assembly, facilitating the cleaning of the stems at the straw discharge port 9 when the straw is blocked;

[0116] (4) The cylinder cover is fixed above the straw discharge support and can be opened or closed together with the straw discharge support.

[0117] Preferably, a limiting piece 7 is also provided on the harvester body, which is correspondingly arranged below the end of the support 1 away from the rotary shaft 2, as shown in Figure 3As shown, the limiting piece 7 is used to block the support 1 from continuing to overturn downward.

[0118] The beneficial effects of the technical scheme of the utility model are:

[0119] When the straw discharging opening 9 of the combine harvester has a straw blocking problem, the straw discharging support can be opened (lifted up) to drive the straw discharging assembly to be lifted up, specifically: first, the pull plate 5 is disassembled and the pull rod is removed, at this time, there is no connection of the pull plate 5, the support 1 is no longer fixed, under the elastic force of the pneumatic support rod spring 4, the support 1 rotates around the rotating shaft 2, the straw discharging support and the straw discharging assembly are lifted up as a whole, and then the straw blocking can be quickly cleaned, the maintenance efficiency during straw blocking is improved, the maintenance convenience is increased, and the straw discharging smoothness is improved.

[0120] When it is necessary to return the straw discharging assembly and the straw discharging support, since the straw discharging support is fixed above the cylinder cover, only the cylinder cover needs to be closed, and the straw discharging support will be closed and returned together with the cylinder cover; after the straw discharging support is returned, the disassembled straw discharging support pull plate 5 is installed back to the original position, so that the straw discharging support is fixed with the thresher body 8, and the purpose of fixing the straw discharging assembly is achieved.

[0121] Through the scheme, when the semi-feeding combine harvester has a straw blocking problem again, it can be quickly solved, manpower and material resources are saved; after the straw discharging support is opened, it can be closed together with the cylinder cover, which is labor-saving and worry-free.
