Description

Technical Field

[0002] The roller drive box is a core component of the threshing and separating system of a wheeled harvester, functioning as a power transmission and gear shifting unit. The peanut harvester's roller drive box has one input end and two output ends; one output end connects to the blower, and the other connects to the roller. The peanut harvester's roller drive box has two shift levers, controlling the blower gear shift and the roller gear shift respectively. By moving the levers, the shift head drives the sliding gear, thus achieving gear shifting.

[0003] Currently, most peanut harvester drum drive boxes on the market can control three speed settings for the drum and two speed settings for the fan. However, because the fan only has two speed settings, the adjustable speed range is small and cannot meet the harvesting speed requirements of the crop, resulting in a high rate of fruit breakage. Furthermore, current peanut harvester drum drive boxes use sliding gear shifting, which is inaccurate and lacks a tactile feel. This can lead to uneven shifting, making shifting difficult and inconvenient for users. Utility Model Content

[0026] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] Example 1 like Figures 1-3 As shown in the figure, a peanut harvester drum transmission box of this embodiment includes a box body 1 and an input shaft 2, a drum transmission shaft 3 and a fan transmission shaft 4 rotatably installed in the box body 1 and arranged in parallel. The input shaft 2 is connected to the drum transmission shaft 3 through a drum speed regulating mechanism, and the input shaft 2 is connected to the fan transmission shaft 4 through a fan speed regulating mechanism. The box body 1 is provided with a drum shifting mechanism 35 that can cooperate with the drum speed regulating mechanism to shift gears, and the box body 1 is also provided with a fan shifting mechanism 5 that can cooperate with the fan speed regulating mechanism to shift gears to realize three-speed regulation of the fan transmission shaft 4.

[0028] like Figure 1 As shown, in a preferred embodiment, a drive bevel gear 34 is integrally connected to the roller drive shaft 3, and an output shaft 6 is rotatably connected inside the housing 1. A passive bevel gear 61 is sleeved and fixed on the output shaft 6, and the drive bevel gear 34 and the passive bevel gear 61 mesh.

[0029] Specifically, in this embodiment, the input shaft 2 is rotatably connected to the housing 1 via the first bearing 11 and the second bearing 12, the roller drive shaft 3 is rotatably connected to the housing 1 via the third bearing 13 and the fourth bearing 14, the fan drive shaft 4 is rotatably connected to the housing 1 via the fifth bearing 15 and the sixth bearing 16, and the output shaft 6 is rotatably connected to the housing 1 via the seventh bearing 17 and the eighth bearing 18.

[0030] In this embodiment, both the fan shifting mechanism and the drum shifting mechanism 35 can adopt commonly used shifting mechanisms in agricultural machinery, such as the fork shaft shifting mechanism.

[0031] In order to improve the adaptability of the roller transmission box of the peanut harvester, the existing two-speed adjustment of the fan has been improved by adding a low speed setting (the existing fan speed adjustment only has medium and high speed settings). This ensures that the peanut vines are sucked away while the peanuts are not sucked away when the whole machine is at full power output, thus reducing the peanut loss rate.

[0032] The peanut harvester drum transmission box in this embodiment, through the cooperation of the fan shifting mechanism and the fan speed regulation mechanism, can realize three-speed regulation of the fan drive shaft. The peanut harvester drum transmission box can provide a wider speed range, and the appropriate gear can be selected according to the dryness and wetness of the crop, reducing the breakage rate and the clogging of the drum during the harvester operation, thereby improving the operation quality and efficiency of the harvester and giving it a greater advantage in the market.

[0033] Example 2 Based on Embodiment 1, this embodiment provides a preferred solution for a fan speed regulating mechanism. For example... Figure 1 and Figure 2As shown, the fan speed regulating mechanism includes a fan drive gear set, a fan low-gear driven gear 41, a fan medium-gear driven gear 43, a fan high-gear driven gear 42, a first gear hub 44, and a second gear hub 45. The fan drive gear set is sleeved and fixed on the input shaft 2. The fan low-gear driven gear 41, the fan high-gear driven gear 42, and the fan medium-gear driven gear 43 are sequentially movably sleeved on the fan drive shaft 4. The first gear hub 44 and the second gear hub 45 are both connected to the fan drive shaft 4 via splines. The first gear hub 44 is located at the fan low-gear driven gear... The second gear hub 45 is located between the high-gear driven gear 42 and the medium-gear driven gear 43 of the fan. The fan shifting mechanism 5 includes a first meshing sleeve 51 and a second meshing sleeve 52. The first meshing sleeve 51 is axially slidably fitted onto a portion of the structure of the low-gear driven gear 41 and the first gear hub 44. The second meshing sleeve 52 is axially slidably fitted onto a portion of the structure of the high-gear driven gear 42, the second gear hub 45, and a portion of the structure of the medium-gear driven gear 43 of the fan. The fan end shifts gears through the meshing sleeves, providing a tactile feedback during shifting, which is convenient for user operation.

[0034] like Figure 1 As shown, specifically, the fan drive gear set in this embodiment includes a fan drive gear 25 and a double gear 26. The fan drive gear 25 and the double gear 26 are respectively sleeved and fixed on the input shaft 2. The fan drive gear 25 meshes with the fan low-gear driven gear 41, and the double gear 26 meshes with the fan medium-gear driven gear 43 and the fan high-gear driven gear 42 respectively. By setting the fan drive gear and the double gear, the assembly of the entire transmission box is convenient, and it is also convenient to mesh with the corresponding gears on the fan drive shaft.

[0035] like Figure 1 As shown, in a preferred embodiment, one end of the input shaft 2 extends into the housing 1, and the fan drive gear 25 is sleeved and fixed at the end of the input shaft 2 extending into the housing 1. The input shaft 2 between the fan drive gear 25 and the double gear 26 is rotatably connected to the housing 1 via a first bearing 11, and the other end of the input shaft 2 near itself is rotatably connected to the housing 1 via a second bearing 12. By setting the fan drive gear and the double gear, the assembly structure of the fan drive shaft is made compact and stable.

[0036] The power transmission route of the fan end of the peanut harvester drum transmission box in this embodiment is as follows: input shaft 2 → fan drive gear 25 + double gear 26 → fan low-gear driven gear 41, fan medium-gear driven gear 43, fan high-gear driven gear 42 → meshing sleeve → gear hub → fan drive shaft 4.

[0037] Example 3 Based on Embodiment 1 or Embodiment 2, this embodiment provides a specific optional solution for a fan speed regulating mechanism. For example... Figure 1 and Figure 2 As shown, the low-gear driven gear 41 of the fan is integrally connected to a low-gear hub 46 on the side near the first meshing sleeve 51. The first meshing sleeve 51 can move onto the low-gear hub 46 and part of the structure of the first hub 44, or move onto the first hub 44. By setting the low-gear hub, it is convenient to cooperate with the first hub to achieve switching between low and high gears.

[0038] like Figure 1 and Figure 2 As shown, in one specific embodiment, the high-gear driven gear 42 of the fan is integrally connected to a high-gear hub 47 on the side near the second meshing sleeve 52, and the medium-gear driven gear 43 of the fan is integrally connected to a medium-gear hub 48 on the side near the second meshing sleeve 52. The second meshing sleeve 52 can move onto the high-gear hub 47, or onto the second hub 45 and a portion of the high-gear hub 47, or onto the second hub 45 and the medium-gear hub 48. By setting the high-gear hub and the medium-gear hub, it is convenient to cooperate with the second hub to realize the switching between high gear and medium gear.

[0039] Example 4 Based on any of the above embodiments, this embodiment provides a specific structure of the fan shifting mechanism 5. For example... Figure 1 and Figure 2 As shown, the fan shifting mechanism 5 further includes a fork shaft 53, a fan shifting rocker arm 55, a fan shifting handle 56, a shift block 54, a first shift fork 57, and a second shift fork 58. The fork shaft 53 is axially movable and installed inside the housing 1, arranged parallel to the fan drive shaft 4. The first shift fork 57 and the second shift fork 58 are respectively fixedly installed on the fork shaft 53, and are respectively connected to the first engagement sleeve 51 and the second engagement sleeve 52, optionally by insertion. The shift block 54 is fixed on the fork shaft 53, and the fan shifting rocker arm 55 is inserted and fixed in the shift block 54. The fan shifting rocker arm 55 is integrally welded and movably connected to the housing 1. The fan shifting handle 56 drives the fan shifting rocker arm to rotate, and when the fan shifting rocker arm 55 rotates, it drives the shift block 54 to move axially, thereby driving the fork shaft 53 to move axially. The fan shifting rocker arm 55 can be arranged perpendicular to the fork shaft 53.

[0040] In this embodiment, the fan shifting mechanism 5 can be locked by a locking plug 19 installed on the housing 1. When the locking plug 19 is fully tightened, it abuts against the shift fork shaft of the shift fork, fixing the shift fork in place.

[0041] The fan gear switching process of the peanut harvester drum transmission box in this embodiment is as follows: the fan shift handle 56 drives the fan shift dial head to move the shift block 54. The shift block 54 is fixed on the fork shaft 53 by bolts. The fork shaft 53 drives the first shift fork 57 and the second shift fork 58 to slide left and right. The first shift fork 57 and the second shift fork 58 respectively move the first engagement sleeve 51 and the second engagement sleeve 52 to engage with different gears, thereby realizing the switching between different gears of the fan.

[0042] High-gear engagement of the fan: The fan shift handle 56 is initially in the low gear position (at this time, the first engagement sleeve 51 is engaged with the low gear hub 46 and the first gear hub 44 respectively). Loosen the fan gear locking plug 19 and rotate the fan shift handle 56 counterclockwise by 25°. The fan shift handle 56 drives the fan shift rocker arm 55 to rotate. The fan shift rocker arm 55 moves the shift block 54 on the fork shaft 53, thereby driving the first shift fork 57 and the second shift fork 58 fixed on the fork shaft 53 to move to the right. The first shift fork 57 and the second shift fork 58 drive the first engagement sleeve 51 and the second engagement sleeve 52 to move to the right, so that the first engagement sleeve 51 only engages with the first gear hub 44, and the second engagement sleeve 52 engages with the high gear hub 47 and the second gear hub 45 on the right side of the high gear driven gear 42 of the fan. The high gear is engaged. Tighten the fan gear locking plug to realize the engagement of the high gear after the low gear of the fan is disengaged.

[0043] Shifting the fan to medium gear: The fan shift handle 56 is initially in the low gear position (at this time, the first engagement sleeve 51 is engaged with the low gear hub 46 and the first gear hub 44 respectively). Loosen the fan gear locking plug 19 and rotate the fan shift handle 56 counterclockwise by 50°. The fan shift handle 56 drives the fan shift rocker arm 55 to rotate. The fan shift rocker arm 55 moves the shift block 54 on the fork shaft 53, thereby driving the first shift fork 57 and the second shift fork 58 fixed on the fork shaft 53 to move to the right. The first shift fork 57 and the second shift fork 58 drive the first engagement sleeve 51 and the second engagement sleeve 52 to move to the right, so that the first engagement sleeve 51 only engages with the first gear hub 44, and the second engagement sleeve 52 engages with the medium gear hub 48 and the second gear hub 45 on the left side of the fan medium gear driven gear 43. Shift the fan to medium gear and tighten the fan gear locking plug 19 to realize the shifting of the fan from low gear to medium gear.

[0044] Low gear engagement of the fan: The fan shift handle 56 is initially in the middle gear position (at this time, the second engagement sleeve 52 is engaged with the middle gear hub 48 and the second gear hub 45 respectively). Loosen the fan gear locking plug 19 and rotate the fan shift handle 56 clockwise by 50°. The fan shift handle 56 drives the fan shift rocker arm 55 to rotate. The fan shift rocker arm 55 moves the shift block 54 on the fork shaft 53, thereby driving the first shift fork 57 and the second shift fork 58 fixed on the fork shaft 53 to move to the left. The first shift fork 57 and the second shift fork 58 drive the first engagement sleeve 51 and the second engagement sleeve 52 to move to the left, so that the first engagement sleeve 51 only engages with the first gear hub 44, and the second engagement sleeve 52 engages with the high gear hub 47 and the second gear hub 45 on the right side of the high gear driven gear 42 of the fan. The high gear is engaged. Tighten the fan gear locking plug 19 to realize the engagement of the low gear after the middle gear of the fan is disengaged.

[0045] Example 5 Based on any of the above embodiments, this embodiment provides an optional structure for the drum speed regulating mechanism. For example... Figure 1 As shown, the drum speed regulating mechanism includes a triple gear 21, a drum middle-gear driven gear 33, a drum high-gear driven gear 32, and a drum low-gear driven gear 31. The triple gear 21 is axially slidably mounted on the input shaft 2. The drum low-gear driven gear 31, drum high-gear driven gear 32, and drum middle-gear driven gear 33 are sequentially mounted and fixed on the drum drive shaft 3. The drum shifting mechanism 35 cooperates with the triple gear 21 and drives the triple gear 21 to move axially, thereby achieving three-speed regulation of the drum drive shaft 3. This embodiment can achieve independent three-speed regulation of the fan and drum, solving the problems of high fruit breakage rate and non-smooth shifting in current peanut transmission boxes on the market. This embodiment uses a "three-speed fan + three-speed drum" configuration to provide a wider speed range for the fan and drum, adapting to different working conditions and reducing the fruit breakage rate.

[0046] In this embodiment, specifically, as shown in... Figure 1 As shown, the triple gear in this embodiment includes a first gear 22, a second gear 23 and a third gear 24 integrally connected.

[0049] The roller gear switching process of the peanut harvester roller drive box in this embodiment is as follows: the roller shifting mechanism switches between the three locking seats of low gear, high gear and medium gear.

[0050] High gear engagement of the drum: The drum shift handle is initially in the middle gear position. Loosen the drum shift handle locking bolt and turn the drum shift handle counterclockwise. The drum shift handle drives the drum shift rocker arm to move the triple gear 21. The triple gear 21 slides to the left on the input shaft 2. The second gear 23 meshes with the drum high gear driven gear 32. The drum shift handle turns to the high gear locking seat and locks with the bolt, realizing the engagement of high gear after disengaging from the middle gear.

[0051] Low gear engagement of the drum: The drum shift handle is initially in the middle gear position. Loosen the drum shift handle locking bolt and turn the drum shift handle counterclockwise. The drum shift handle drives the drum shift rocker arm to move the triple gear 21. The triple gear 21 slides to the left on the input shaft 2. The first gear 22 meshes with the drum low gear driven gear 31. The drum shift handle turns to the low gear locking seat and locks with the bolt, realizing the engagement of the low gear after the middle gear is disengaged.

[0052] Mid-gear engagement of the drum: The drum shifter handle is initially in the low gear position. Loosen the drum shifter handle locking bolt and turn the drum shifter handle clockwise.
