Description

Technical Field

[0001] This application belongs to the field of corn harvester technology, specifically relating to a peeling mechanism for a corn harvester and a corn harvester. Background Technology

[0002] A corn harvester is an agricultural machine specifically designed for harvesting corn. It can quickly and efficiently cut corn stalks from the field, significantly improving harvesting efficiency and saving considerable labor and time costs compared to manual harvesting. Corn harvesters typically include a peeling mechanism, but most existing peeling mechanisms consist of several peeling rollers fixed sequentially to the machine's frame. This fixed structure means that when a single part in the peeling mechanism wears out or malfunctions, the entire mechanism must be disassembled and the faulty part replaced, leading to difficult and time-consuming maintenance.

If a component in one or a few peeling roller modules of the peeling mechanism is damaged and needs to be replaced or repaired, the operator only needs to remove the damaged peeling roller module from the peeling roller bracket and repair or replace the damaged component. There is no need to dismantle the entire peeling mechanism. Therefore, the peeling mechanism has a simple structure and achieves a modular design, facilitating the repair or replacement of damaged components, reducing maintenance costs and difficulty, and improving maintenance convenience.

Detailed Implementation

[0037] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0038] Embodiments of this application provide a peeling mechanism for a corn harvester, such as... Figures 1-3 As shown, the peeling mechanism includes:

[0039] Peeling roller bracket 1, with an installation space 101 formed on peeling roller bracket 1;

[0040] The drive shaft assembly 2 is mounted on the peeling roller bracket 1 and located on one side of the mounting space 101;

[0041] Multiple peeling roller modules 3 are arranged in the installation space 101 and each includes a support plate assembly 301 and a peeling roller assembly 302. The peeling roller assembly 302 is arranged on the top of the support plate assembly 301 and is drivenly connected to the drive shaft assembly 2. The support plate assembly 301 is detachably connected to the peeling roller bracket 1.

[0042] Specifically, the corn harvester also includes a peeling machine frame and a drive component (such as a motor). The peeling roller bracket 1 is mounted on the peeling machine frame. The drive shaft assembly 2 includes a drive shaft 201 and a first transmission wheel 202 mounted on the drive shaft 201 (in this embodiment, the first transmission wheel 202 can be a bevel gear). There are multiple peeling roller modules 3 (in this embodiment, there are five peeling roller modules 3). The multiple peeling roller modules 3 are distributed laterally in the installation space 101. The peeling mechanism also includes a second transmission wheel 12 (in this embodiment, the second transmission wheel 12 can be a bevel gear) that meshes with the first transmission wheel 202 and can transmit power to the peeling roller modules 3. The drive shaft 201 is drivenly connected to the drive component. Multiple peeling roller modules 3 are mounted on the peeling roller bracket 1 and then integrated with the drive shaft assembly 2 (as well as the first transmission wheel 202 and the second transmission wheel 12) to form a whole. This enables the peeling mechanism to perform the peeling function. When the peeling mechanism needs to perform the peeling function, the drive component drives the drive shaft 201 to rotate. The drive shaft 201 then transmits power to each peeling roller module 3 through the first transmission wheel 202 and the second transmission wheel 12, so that the peeling roller modules 3 can peel the harvested corn ears. If one or a few parts of the peeling roller modules 3 in the peeling mechanism are damaged and need to be replaced or repaired, the operator only needs to remove the damaged peeling roller module 3 from the peeling roller bracket 1 and repair or replace the damaged parts. Unlike the prior art, it does not require the entire peeling mechanism to be dismantled. In other words, the peeling mechanism in this embodiment has a simple structure and realizes a modular design, which facilitates the repair or replacement of damaged parts, reduces the maintenance cost and difficulty of the peeling mechanism, and improves the convenience of maintenance.

[0043] In one embodiment of this application, such as Figure 4 As shown, the support plate assembly 301 includes a first support plate 3011 and a second support plate 3012 distributed longitudinally at intervals. The first end of the peeling roller assembly 302 is connected to the first support plate 3011, and the second end of the peeling roller assembly 302 is connected to the second support plate 3012. Both the first support plate 3011 and the second support plate 3012 are detachably connected to the peeling roller bracket 1.

[0044] Specifically, the peeling roller module 3 also includes a first bearing assembly and a second bearing assembly. The first end of the peeling roller assembly 302 is connected to the first support plate 3011 through the first bearing assembly, and the second end of the peeling roller assembly 302 is connected to the second support plate 3012 through the second bearing assembly, so that each peeling roller in the peeling roller assembly 302 can rotate relative to the support plate assembly 301. The peeling roller bracket 1 has a first mounting notch and a second mounting notch 3016 formed on its first and second longitudinal vertical sidewalls, respectively, for the first support plate 3011 and the second support plate 3012 to be inserted downwards. The lower ends of the first support plate 3011 on both sides are also formed with a first groove that is recessed from bottom to top. The first longitudinal vertical sidewall of the peeling roller bracket 1 has a first protrusion for extending into the first groove. Similarly, the lower ends of the second support plate 3012 on both sides are also formed with a second groove that is recessed from bottom to top. The second longitudinal vertical sidewall of the peeling roller bracket 1 has a second protrusion for extending into the second groove. The above structure is simple in design and easy to manufacture. The peeling roller module 3 can be quickly installed on the peeling roller bracket 1 by inserting the first protrusion into the first groove and the second protrusion into the second groove. In another embodiment of this application, two sets of bolt assemblies can be used to detachably connect the first support plate 3011 and the second support plate 3012 to the peeling roller bracket 1, respectively. Alternatively, two connecting pins can be used to detachably connect the first support plate 3011 and the second support plate 3012 to the peeling roller bracket 1, respectively.

[0045] In one embodiment of this application, the peeling mechanism further includes a slide rail assembly 303 disposed on the peeling roller bracket 1 and located at the bottom of the mounting space 101, wherein the first support plate 3011 is slidably connected to the slide rail assembly 303 and can slide along the slide rail assembly 303.

[0046] Specifically, in this embodiment, the number of slide rail assemblies 303 is the same as the number of peeling roller modules 3. The slide rail assembly 303 includes multiple slide rails, and the number of slide rails is the same as the number of first protrusions (or second protrusions). In the transverse direction, the position of the first protrusion corresponds to the position of the second protrusion. One end of the slide rail is connected to the first protrusion, and the other end of the slide rail is connected to the second protrusion. The width of the slide rail is less than or equal to the width of the first slot. When installing the peeling roller module 3, the first support plate 3011 is first placed on the slide rail assembly 303, and each slide rail is inserted into the first slot of the first support plate 3011. Then, the operator applies a pushing force to the peeling roller module 3 so that the first support plate 3011 slides along the axial direction of the slide rail assembly 303 towards the direction of the drive shaft assembly 2, thereby quickly pushing the peeling roller module 3 into the installation space 101 for installation. When it is necessary to disassemble the peeling roller module 3, the operator applies an outward pulling force to the peeling roller module 3 so that the peeling roller module 3 is pulled out of the installation space 101, which can quickly disassemble the peeling roller module 3 and further shorten the time spent on installing or disassembling the peeling roller module 3.

[0047] In one embodiment of this application, the peeling mechanism further includes a limiting plate 304 disposed on the peeling roller bracket 1 and used to limit the installation position of the first support plate 3011.

[0048] Specifically, the limiting plate 304 is set on the peeling roller bracket 1 and located at one end of the slide rail assembly 303 near the drive shaft assembly 2. When installing the peeling roller module 3, the operator applies a pushing force to the peeling roller module 3 to move the first support plate 3011 along the slide rail assembly 303 to a position close to the limiting plate 304. The limiting plate 304 then acts as a stop for the first support plate 3011 (i.e., the peeling roller module 3), preventing the first support plate 3011 (i.e., the peeling roller module 3) from continuing to move in the direction of the drive shaft assembly 2. The setting of the limiting plate 304 helps to improve the installation accuracy of the peeling roller module 3 and further improves the installation convenience of the peeling roller module 3.

[0049] In one embodiment of this application, such as Figure 3 As shown, the second support plate 3012 has vertically distributed strip-shaped connecting holes 3013, and the peeling mechanism also includes:

[0050] The first connector 4 has its first end engaged on the side end face of the second support plate 3012, and its second end passes through the strip-shaped connecting hole 3013 and extends into the installation space 101.

[0051] A locking plate 5 is disposed in the installation space 101 and connected to the second end of the first connector 4, for locking the second support plate 3012 and the peeling roller bracket 1.

[0052] Specifically, the strip-shaped connecting holes 3013 are vertically distributed on the second support plate 3012, and the first end of the first connector 4 is engaged on the side end face of the second support plate 3012 away from the installation space 101. The width of the locking plate 5 is greater than the width of the strip-shaped connecting holes 3013. Force is applied to the first connector 4 so that when the first connector 4 moves along the length direction of the strip-shaped connecting holes 3013, the locking plate 5 also moves vertically accordingly. When the first connector 4 is located at the lowest end of the strip-shaped connecting hole 3013, the locking plate 5 simultaneously locks the second support plate 3012 and the peeling roller bracket 1, preventing the peeling roller module 3 from moving away from the limiting plate 304 due to accidental force and thus detaching from the peeling roller bracket 1. This further ensures the reliability of the connection between the peeling roller module 3 and the peeling roller bracket 1 after installation. If it is necessary to disassemble the peeling roller bracket 1, the operator applies force to the first connector 4 so that the first connector 4 drives the locking plate 5 to move upward, thereby preventing the locking plate 5 from simultaneously locking the second support plate 3012 and the peeling roller bracket 1. Then, a pulling force is applied to the peeling roller module 3 to pull it out of the installation space 101.

[0053] In one embodiment of this application, such as Figures 4-5 As shown, the second support plate 3012 is provided with vertically distributed grooves 3014. The peeling mechanism also includes a sliding member 3015 connected to the first connecting member 4 and slidable along the length of the groove 3014. The sliding member 3015 has an insertion hole. The peeling mechanism also includes:

[0054] The first ear plate 6 is disposed on the second support plate 3012 and located on one side of the slider 3015;

[0055] The second ear plate 7 is disposed on the second support plate 3012 and located between the first ear plate 6 and the sliding member 3015;

[0056] The locking shaft 8 is movably inserted into the first ear plate 6 and the second ear plate 7, and a locking end is formed on the locking shaft 8 that can be inserted into the socket.

[0057] Specifically, in this embodiment, there are two slide grooves 3014 (slide grooves 3014 do not penetrate the second support plate 3012). The two slide grooves 3014 are respectively arranged on both sides of the strip-shaped connecting hole 3013. The sliding member 3015 includes a connecting part and two sliding parts arranged on both sides of the connecting part. The sliding parts can move along the length direction of the slide groove 3014. One end of the first connecting member 4 is locked on the connecting part. The other end of the first connecting member 4 passes through the connecting part and the strip-shaped connecting hole 3013 and is connected to the locking plate 5. When the first connecting member 4 moves along the length direction of the strip-shaped connecting hole 3013, the sliding member 3015 also moves along the length direction of the slide groove 3014. The insertion hole is located on the sliding part of the slider 3015 near the second ear plate 7, with its opening facing the second ear plate 7. The first ear plate 6 and the second ear plate 7 are respectively provided with a first through hole and a second through hole. The locking end of the locking shaft 8 can pass through the first through hole and the second through hole and extend into the insertion hole, preventing the first connecting piece 4 and the locking plate 5 from sliding down due to gravity after being lifted, which would affect the installation or disassembly of the peeling roller module 3, and further improve the ease of use of the peeling mechanism. After the peeling roller module 3 is engaged on the peeling roller bracket 1, the locking shaft 8 is moved to move the slider 3015, the first connecting piece 4 and the locking plate 5 downward, thereby locking the peeling roller module 3 and the peeling roller bracket 1.

[0058] Furthermore, in this embodiment, the sliding member 3015 and the sliding groove 3014 can also prevent the connecting member from rotating relative to the second support plate 3012, which is beneficial for the locking end to be quickly inserted into the socket.

[0059] In one embodiment of this application, the peeling mechanism further includes an elastic clamping member 9 disposed on the locking shaft 8 and used to press the locking end into the insertion hole.

[0060] Specifically, the locking assembly also includes a first limiting pin and a second limiting pin. The first limiting pin is inserted radially on the locking shaft 8 and located on the side of the first ear plate 6 away from the second ear plate 7. The second limiting pin is inserted radially on the locking shaft 8 and located between the first ear plate 6 and the second ear plate 7. The arrangement of the first limiting pin and the second limiting pin can prevent the locking shaft 8 from disengaging from the first ear plate 6. The locking shaft 8 also has an annular stop portion located between the second limiting pin and the first ear plate 6. In this embodiment, the elastic clamping member 9 can be a spring. One end of the spring abuts against the first ear plate 6, and the other end of the spring abuts against the stop portion. When it is necessary to lock the first connecting member 4 and the locking plate 5, the operator pulls the locking shaft 8 away from the locking member and compresses the spring, then moves the first connecting member 4 upward so that the insertion hole is aligned with the locking end. After that, the locking shaft 8 is released, and the locking shaft 8 can move under the elastic action of the elastic clamping member 9 and drive the locking end to be inserted into the insertion hole, which improves the ease of use of the locking assembly. In addition, the setting of the elastic clamping member 9 can also press the locking end into the insertion hole during the installation or disassembly of the peeling roller module 3, preventing the first connecting member 4 and the locking plate 5 from moving downward due to gravity.

[0061] In one embodiment of this application, the peeling mechanism further includes a first peeling force adjustment component 10 and a second peeling force adjustment component 11 disposed on the support plate assembly 301 and used to work together to adjust the peeling force of the peeling roller module 3. The first peeling force adjustment component 10 and the second peeling force adjustment component 11 are respectively disposed at both ends of the axial direction of the peeling roller assembly 302. Adjusting the first peeling force adjustment component 10 and the second peeling force adjustment component 11 can adjust the peeling force of the peeling roller module 3, so that the peeling mechanism can adapt to corn ears in different harvesting states, which is beneficial to expanding the application range of the peeling mechanism and the corn harvester.

[0062] In one embodiment of this application, the peeling roller module 3 includes a first peeling roller 305, a second peeling roller 306 fixed on the support plate assembly 301, and a third peeling roller 307 and a fourth peeling roller 308 located outside the first peeling roller 305 and the second peeling roller 306. The first peeling force adjustment assembly 10 and the second peeling force adjustment assembly 11 both include:

[0063] The second connector 1101 is pivotally mounted on the support plate assembly 301 about the first pivot center, and the first end of the second connector 1101 is connected to the third peeling roller 307.

[0064] The third connector 1102 is pivotally mounted on the support plate assembly 301 about the second pivot center, and the first end of the third connector 1102 is connected to the fourth peeling roller 308.

[0065] A connecting shaft 1103 is provided, with its first end connected to the second end of the third connecting member 1102, and the second end of the connecting shaft 1103 passing through the second end of the second connecting member 1101.

[0066] Adjusting member 1104 is disposed on connecting shaft 1103 and located between the second end of third connecting member 1102 and the second end of second connecting member 1101. Adjusting member 1104 and connecting shaft 1103 form a threaded connection.

[0067] The elastic element 1105 is sleeved on the outside of the connecting shaft 1103. One end of the elastic element 1105 abuts against the second end of the second connecting element 1101, and the other end of the elastic element 1105 is connected to the adjusting element 1104.

[0068] Specifically, in this embodiment, the first peeling roller 305 and the second peeling roller 306 are both spiral rollers, and the third peeling roller 307 and the fourth peeling roller 308 are both fish-scale rollers. The first bearing assembly includes four first bearings, and the second bearing assembly includes four second bearings. The first ends of each of the first peeling roller 305, the second peeling roller 306, the third peeling roller 307, and the fourth peeling roller 308 are respectively connected to the first support plate 3011 through the four first bearings. Among them, the two first bearings connected to the first peeling roller 305 and the second peeling roller 306 are fixed to the first support plate 3011. The first bearing connected to the third peeling roller 307 is located at the upper end of the second connecting member 1101 of the first peeling force adjustment assembly 10, and the first bearing connected to the fourth peeling roller 308 is located in the first peeling force adjustment assembly 10. The upper end of the third connecting member 1102; similarly, the second ends of the first peeling roller 305, the second peeling roller 306, the third peeling roller 307 and the fourth peeling roller 308 are respectively connected to the second support plate 3012 through four second bearings. Among them, the two second bearings connected to the first peeling roller 305 and the second peeling roller 306 are fixed to the second support plate 3012, the second bearing connected to the third peeling roller 307 is located at the upper end of the second connecting member 1101 of the second peeling force adjustment assembly 11, and the second bearing connected to the fourth peeling roller 308 is located at the upper end of the third connecting member 1102 of the second peeling force adjustment assembly 11. The above arrangement allows the first peeling roller 305, the second peeling roller 306, the third peeling roller 307 and the fourth peeling roller 308 to pivot around their respective central axes.

[0069] The peeling roller module 3 in this embodiment also includes a third drive wheel, a fourth drive wheel, a fifth drive wheel, and a sixth drive wheel respectively disposed on the first peeling roller 305, the second peeling roller 306, the third peeling roller 307, and the fourth peeling roller 308. Each of the four drive wheels meshes with the other drive wheel adjacent to it, thereby realizing the sequential transmission of power. Further, the third or fourth drive wheel is the driving wheel of the peeling roller module 3, and the fifth and sixth drive wheels are driven wheels. That is, after the second drive wheel 12 drives the first peeling roller 305 or the second peeling roller 306 to rotate, the drive wheel on the first peeling roller 305 or the second peeling roller 306 then transmits power to the drive wheels on the other peeling rollers, thereby enabling the peeling roller module 3 to perform the peeling function.

[0070] The first peeling force adjustment assembly 10 and the second peeling force adjustment assembly 11 both include a fourth connector. The fourth connector of the first peeling force adjustment assembly 10 is disposed on the first support plate 3011, and the first bearings connected to the first peeling roller 305 and the second peeling roller 306 are all disposed at the top of the fourth connector of the first peeling force adjustment assembly 10. The fourth connector of the second peeling force adjustment assembly 11 is disposed on the second support plate 3012, and the second bearings connected to the first peeling roller 305 and the second peeling roller 306 are all disposed at the top of the fourth connector of the second peeling force adjustment assembly 11.

[0071] In the first peeling force adjustment assembly 10 (or the second peeling force adjustment assembly 11), the second connecting member 1101 is pivotally mounted on the first support plate 3011 (or the second support plate 3012) at its middle position via a first connecting pin, meaning the first pivot center is the axial center of the first connecting pin. Similarly, the third connecting member 1102 is pivotally mounted on the first support plate 3011 (or the second support plate 3012) at its middle position via a second connecting pin, meaning the second pivot center is the axial center of the second connecting pin. Both the first peeling force adjustment assembly 10 and the second peeling force adjustment assembly 11 also include a fifth connecting member whose two ends are respectively connected to the first connecting pin and the second connecting pin. The inclusion of the fifth connecting member enhances the reliability of the connections between the components of the peeling roller module 3.

[0072] In this embodiment, the adjusting member 1104 is an adjusting nut, and the elastic member 1105 can be a spring sleeved on the outside of the connecting shaft 1103. The second end of the second connecting member 1101 has a through hole through which the second end of the connecting shaft 1103 can pass. The diameter of the second end of the connecting shaft 1103 is smaller than the diameter of the first end of the connecting shaft 1103, and the diameter of the second end of the connecting shaft 1103 is also smaller than the diameter of the through hole. When it is necessary to increase the peeling force of the peeling roller module 3, adjust the adjusting nut on the connecting shaft 1103 to shorten the length of the elastic element 1105. Under the elastic action, the elastic element 1105 pushes the second connecting element 1101 to pivot around the first pivot center (or makes the second connecting element 1101 tend to pivot around the first pivot center). The first end of the second connecting element 1101 drives the third peeling roller 307 to move closer to the adjacent first peeling roller 305 (or increases the squeezing force on the first peeling roller 305). At the same time, under the elastic action, the elastic element 1105 drives the connecting shaft 1103 away from the second connecting element 1101. The direction is moved so that the third connector 1102 pivots around the second pivot center (or the third connector 1102 tends to pivot around the second pivot center). The first end of the third connector 1102 drives the fourth peeling roller 308 to move closer to the adjacent second peeling roller 306 (or increases the squeezing force on the second peeling roller 306), thereby increasing the force between the spiral roller and the fish scale roller. Conversely, by adjusting the adjusting nut on the connecting shaft 1103 to extend the length of the elastic member 1105, the force between the spiral roller and the fish scale roller can be reduced. The peeling force adjustment of the peeling roller module 3 is achieved in the above way.

[0073] Furthermore, in this embodiment, both the first peeling force adjustment component 10 and the second peeling force adjustment component 11 include a first adjustment reinforcement 1106 and a second adjustment reinforcement 1107. Both the first adjustment reinforcement 1106 and the second adjustment reinforcement 1107 are nuts. The first adjustment reinforcement 1106 is tightly attached to the adjusting component 1104, which can further strengthen the connection between the adjusting component 1104 and the connecting shaft 1103 and prevent the adjusting component 1104 from moving relative to the connecting shaft 1103 due to insufficient connection. The second adjustment reinforcement 1107 is disposed on the connecting shaft 1103 and is tightly attached to the third connecting component 1102, which can prevent the third connecting component 1102 from moving relative to the connecting shaft 1103 due to insufficient connection. The arrangement of the first adjustment reinforcement 1106 and the second adjustment reinforcement 1107 further improves the practicality of the peeling mechanism.
