Description

Technical Field

[0001] The present invention relates to a wheeled oil-tea camellia harvester adaptable to slope operation, belonging to the technical field of fruit harvesters. Background Art

[0002] The use of mechanical harvesters in orchards can greatly improve the harvesting efficiency. However, affected by factors such as the undulating terrain, the use and promotion of harvesters are restricted to a certain extent. In order to adapt to the uneven terrain changes in the orchard, CN112088654A discloses a fruit harvester, in which a jacking component for changing the tilt angle of the belt fruit output mechanism is installed on the crawler-type traveling mechanism, and the belt fruit output mechanism is hinged to the jacking component, so that the fruit collection mechanism can adjust its undulation automatically according to the change of the ground height, prevent the chassis from inserting into the soil, meet the harvesting requirements of fruits and nuts in potholed mountainous and hilly areas, and improve the terrain adaptability and practicability of the whole machine. CN111011002A discloses a fruit and nut harvester, in which the U-shaped positioning chassis moves under the drive of the centering component, can be telescoped back and forth, lifted and lowered, and swung left and right. When the traveling mechanism cannot approach the tree trunk closely, the centering component moves to effectively position the loading mechanism on the tree trunk, extend the movement range of the loading mechanism, reduce the traveling requirements of the traveling mechanism for the terrain, and ensure that the loading mechanism can be effectively positioned at the most suitable position on the tree trunk according to the position, thickness and height of the tree trunk, meeting the requirements of vibrating and collecting fruits and nuts in potholed mountainous and hilly areas.

[0003] For the first above-mentioned harvester, the fruit collection mechanism rises and falls with the movement of the jacking component, and adjusts its undulation to adapt to the terrain. The jacking mechanism is controlled by an oil cylinder. During the operation of the harvester, manual control of the oil cylinder telescoping is required to make the fruit collection mechanism rise and fall. For the second harvester, the vibration collection requirement of fruits on uneven terrain is realized by adjusting the position of the U-shaped positioning chassis. However, the oil-tea camellia tree species have low requirements for the terrain and have many planting scenarios. It can be planted not only on the uneven orchard land with high and low undulations, but also on the sloping land with a certain slope. However, when the harvester operates on a large slope, due to the inclination of the diesel engine, the power is prone to be incoherent, and the height difference between the front and rear ends of the fruit collection mechanism is too large, resulting in easy rolling out of fruits during the fruit output process, and the fruit output efficiency is low. How to make the harvester adapt to slope harvesting operations and improve the harvesting efficiency and reliability is the purpose of the research and development of the present invention. Summary of the Invention

[0004] The wheeled camellia oil harvester that can adapt to slope operations provided by the present invention ensures that the harvester can adapt to the working conditions of the engine when operating on a larger slope, thereby improving the reliability and stability of the power output of the harvester; reduces the probability of fruit running away during the fruit output process of the fruit output mechanism when operating on a slope, thereby improving the fruit output efficiency and the harvesting rate; improves the position stability of the harvester when operating on a slope, thereby making the harvester adaptable to slope harvesting operations and improving the harvesting efficiency and reliability.

[0029] The beneficial effects of the invention are:

[0030] In the wheeled tea oil harvester adapted for slope operations of the present invention, the engine is connected to the frame via an angle adjustment assembly. The movement of the angle adjustment assembly drives the engine to swing and adjust the tilt angle, reducing the engine's tilt angle when operating on a slope. This prevents the loss of lubricating oil inside the engine, which causes poor lubrication or damage to the internal power source, and ensures that the harvester can adapt to the engine's operating conditions when operating on larger slopes, thereby improving the reliability and stability of the harvester's power output. The fruit output mechanism is supported above the main gearbox by an adjustable support rod assembly. The tilt angle of the fruit output mechanism is adjusted by adjusting the support rod assembly, reducing the probability of fruit escaping during the fruit output process when operating on a slope, improving fruit output efficiency, and increasing the harvest rate. The vibrator in the vibrating claw mechanism is suspended from the fruit output mechanism. The center of gravity of the harvester can be adjusted by the vibrator, improving the positional stability of the harvester during slope operations, making the harvester adaptable to slope harvesting operations, and improving harvesting efficiency and reliability.

[0031] The output ball head sleeve and the input ball head are correspondingly sleeved to ensure normal torque transmission when the engine output shaft and the auxiliary transmission input shaft form an angle, so that the adjustment of the engine tilt angle will not affect the transmission of the harvester, thereby improving the transmission reliability of the harvester.

[0032] Adjusting the setting of the support rod assembly makes the swing amplitude of the rear end of the fruit output mechanism smaller than the swing amplitude of the front end of the fruit output mechanism, which is beneficial to reducing the forward tilt slope of the fruit output mechanism, reducing the height difference between the rear end and the front end of the fruit output mechanism, and reducing the probability of the fruit rolling down due to gravity during the process of outputting the fruit to the rear end, thereby improving the fruit output efficiency and the harvest rate.

[0033] The scraper in the output chain scraper assembly is hinged on the chain crossbar through a spring hinge. The fruit in the collecting umbrella mechanism is pushed backward as the conveyor chain moves, realizing the automatic output and collection of vibration-picked fruit. When the downward force of the fruit on the scraper is greater than the elastic force of the spring hinge, the scraper will swing downward, releasing the fruit and rolling it downward to avoid the phenomenon that too much fruit accumulates on the scraper and causes the conveyor chain to fail to operate normally. When a large amount of fruit accumulates on the scraper, the card automatically swings down to abandon the fruit, avoiding the conveyor chain from being stuck, reducing the fruit output jam rate, ensuring the normal operation of the conveyor chain, and improving the fruit output efficiency.

[0034] The length of the crank in the crank-rocker assembly is smaller than the length of the rocker. The electric push rod can push the rocker to rotate a small angle to enable the crank to obtain a larger rotation angle, thereby increasing the rotation angle of the crank shaft and enabling the active sprocket to obtain a larger rotation angle, so as to increase the working stroke of the roller chain within a limited space, that is, to increase the rotation angle of the active umbrella rib, to ensure that the electric push rod can drive the collecting umbrella assembly to fully open within the stroke range, and the two collecting umbrella assemblies are spliced ​​to form a complete collecting umbrella, thereby improving the opening and closing reliability and efficiency of the collecting umbrella.

[0035] The main gearbox has multiple gears including forward, reverse, parking, vibration and conveying. The final stage of the forward and reverse gears is a worm gear transmission, which utilizes the self-locking characteristics of the worm gear to avoid the danger of the harvester body sliding backward due to inertia when harvesting on a slope. It can prevent slipping when the power source is separated, such as during travel and parking, clutch disengagement, gear sliding, etc., thereby improving the stability and safety of the harvester operating on a slope.

[0051] The following combination Figures 1 to 15 The embodiments of the present invention are described in detail.

[0052] The wheeled tea oil harvester, which can be adapted to slope operations, comprises a frame 1 with running wheels, a vibrating claw mechanism 2 that can clamp the tree trunk to transmit vibration, a collecting umbrella mechanism 3 that receives the shaken-off fruits, a fruit output mechanism 4 that outputs the fruits in the collecting umbrella mechanism 3 backward, a power mechanism installed on the frame 1 to provide power to each mechanism, and an operating table 5 for controlling the actions of each mechanism. The fruit output mechanism 4 is arranged obliquely on the front side of the frame 1, the collecting umbrella mechanism 3 is installed at the front end of the fruit output mechanism 4, and the vibrating claw mechanism 2 is connected to the fruit output mechanism 4 and extends to the front end of the fruit output mechanism 4. The present invention is characterized in that:

[0053] The power mechanism includes a hydraulic system, an engine 6 connected to the hydraulic system, an auxiliary transmission 7 connected to the output end of the engine 6, and a main transmission 8 connected to the auxiliary transmission 7 via a clutch 70. The engine 6 is connected to the frame 1 via an angle adjustment component 9. The angle adjustment component 9 obtains power from the hydraulic system and is controlled by the operating console to drive the engine 6 to swing and adjust the tilt angle.

[0054] The fruit output mechanism 4 is supported above the main gearbox 8 by an adjustable support rod assembly 10. The adjustable support rod assembly 10 obtains power from the hydraulic system and is controlled by the operating console 5 to drive the fruit output mechanism 4 to swing and adjust the tilt angle;

[0055] The fruit output mechanism 4 includes a fruit output rack 11 connected to the adjustment support assembly and arranged obliquely, and an output chain scraper assembly 12 mounted on the fruit output rack 11 and transmission-connected to the main gearbox 8;

[0056] The vibrating clamping mechanism 2 includes a vibrator 13 suspended on the fruit output mechanism 4 and transmission-connected to the main gearbox 8, and a clamping claw assembly 14 connected to the vibrator and extending to the front end of the fruit output mechanism 4;

[0057] The collecting umbrella mechanism 3 includes an electric push rod assembly 15 installed at the front end of the fruit output mechanism 4 and a collecting umbrella assembly 16 connected to the electric push rod assembly 15. The collecting umbrella assembly 16 opens or closes with the movement of the electric push rod 15.

[0058] In the aforementioned wheeled tea oil harvester adapted for slope operations, the engine 6 is connected to the frame 1 via an angle adjustment assembly 9. The angle adjustment assembly 9 drives the engine 6 to swing and adjust the tilt angle. This reduces the tilt angle of the engine 6 during slope operations, preventing internal lubrication problems or damage to the engine caused by a loss of lubricating oil during slope operations. This ensures that the harvester can adapt to the engine's operating conditions on larger slopes, improving the reliability and stability of the harvester's power output. The fruit delivery mechanism 4 is supported above the main gearbox 8 by an adjustable support rod assembly 10. Adjusting the support rod assembly 6 adjusts the tilt angle of the fruit delivery mechanism, reducing the probability of fruit escaping during the delivery process during slope operations, improving fruit delivery efficiency, and increasing the harvest rate. The vibrator 13 in the vibrating claw mechanism is suspended from the fruit delivery mechanism 4. The vibrator 13 adjusts the center of gravity of the harvester, improving the positional stability of the harvester during slope operations, making the harvester adaptable to slope harvesting operations and improving harvesting efficiency and reliability.

[0059] The angle adjustment assembly 9 includes an engine mount 91 and an engine lift cylinder 92 hinged to the frame 1. One end of the engine lift cylinder 92 is hinged to the engine mount 91, and the other end is hinged to the frame 1. The engine 6 is fixed to the engine mount 91 and swings relative to the frame 1 to adjust the tilt angle as the engine lift oil 92 expands and contracts. The engine 6 is fixed to the engine mount 91. One end of the engine lift cylinder 92 is hinged to the frame 1, and the other end is hinged to the engine mount 91. One end of the engine mount 91 is hinged to the frame 1 and supported by the engine lift cylinder 92. The engine lift cylinder 92 pushes the engine mount 91 to swing upward, reducing the downward tilt angle of the engine when operating on a slope, avoiding the downward tilt of the oil caused by the tilt of the engine oil tank, affecting the oil supply efficiency and causing discontinuous power output, and ensuring that the harvester can adapt to the working conditions of the engine when operating on a larger slope.

[0060] Among them, the output shaft end of the engine 6 has an output ball head sleeve 61, and the input shaft of the auxiliary transmission 7 has an input ball head 71 that cooperates with the output ball head sleeve 61. The input ball head 71 is in the shape of a drum with a spherical outer wall, and hemispherical hemispherical protrusions 72 are evenly distributed on the outer wall of the input ball head 71. The output ball head sleeve 61 has a spherical inner cavity that cooperates with the spherical surface of the input ball head, and the spherical inner cavity has a hemispherical groove 62 corresponding to the hemispherical protrusion. The output ball head sleeve 61 and the input ball head 71 are correspondingly sleeved to transmit the power of the output shaft of the engine 6 to the input shaft of the auxiliary transmission 7. Since the output shaft of the engine 6 will change its angle as the inclination angle of the engine 6 is adjusted, in order to ensure that the engine 6 can be connected to the input shaft of the auxiliary transmission 7 when adjusted to any angle to realize power transmission, an output ball head sleeve 61 is provided at the output end of the engine, and an input ball head 71 is provided on the input shaft of the auxiliary transmission. The output ball head sleeve 61 spherically fits on the input ball head 71 so that the two can swing relative to each other axially to form an angle. The hemispherical protrusion 72 cooperates with the hemispherical groove 62 to ensure that the output ball head 61 will drive the input ball head 71 to rotate circumferentially, and ensure normal torque transmission when the engine output shaft and the auxiliary transmission input shaft form an angle. The adjustment of the engine inclination angle will not affect the transmission of the harvester, thereby improving the transmission reliability of the harvester.

[0061] Among them, the adjusting support rod assembly 10 includes an upper support rod 101 respectively hinged on both sides of the fruit output mechanism 4, a lower support rod 102 arranged below the upper support rod 101 and respectively hinged on both sides of the fruit output mechanism 4, and an adjusting cylinder 103 hinged on the frame 1 and hinged to the upper support rod 101. The upper support rod 101 and the lower support rod 102 are respectively hinged to the main gearbox 8. The adjusting cylinder 103 obtains power from the hydraulic system to push the upper support rod 101 to swing around the hinge point between it and the main gearbox 8, thereby driving the fruit output mechanism 4 and the lower support rod 102 to swing synchronously to adjust the inclination angle of the fruit output mechanism 4. As can be seen from the accompanying drawings, the upper support rod 101 and the lower support rod 102 are respectively arranged on both sides of the fruit output mechanism 4 and are respectively hinged on the main gearbox 8. The lower end of the upper support rod 101 is hinged to the adjusting cylinder 103. The adjusting cylinder 103 obtains power from the engine 1 to form telescopic movement, driving the upper support rod 101 to swing around the hinge point between it and the main gearbox 8. The swing of the upper support rod 101 will drive the fruit output mechanism 4 to swing, and the fruit output mechanism 4 will drive the lower support rod 102 to swing. The upper support rod 101, the lower support rod 102, the main gearbox 8 and the fruit output mechanism 4 are surrounded to form a quadrilateral. The main gearbox 8 is the fixed side of the quadrilateral and cannot move, and the other three sides can move. The deformation of the quadrilateral is driven by the swing of the upper support rod 101, so that the swing adjustment of the inclination angle of the fruit output mechanism 4 is realized.

[0062] The upper support rod 101 is composed of an upper section 104 and a lower section 105 integrally formed at the lower end of the upper section 104 and forming a bending angle with the upper section 104. The regulating cylinder 103 is hinged to the lower section 105. The upper end of the upper section 104 is hinged to the fruit output mechanism 4, and the lower end is hinged to the upper fixed rod 17 fixed on the main gearbox 8. One end of the lower support rod 102 is hinged to the fruit output mechanism 4 and the other end is hinged to the lower fixed rod 18 fixed on the main gearbox 8. The upper fixed rod 17 is arranged parallel to and obliquely above the lower fixed rod 18. The length of the upper section 104 is less than the straight-line distance between the two ends of the lower support rod 102. Figure 4 、 5 As shown, the upper section 104 is located above the lower support rod 102, the upper section 104 is close to the rear end of the fruit output mechanism 4, and the lower support rod 102 is close to the front end of the fruit output mechanism. The upper section 104 is the rotation radius of the fruit output mechanism 4 driven by the upper support rod 101 to swing, and the lower support rod 102 is curved. The straight-line distance between the two ends of the lower support rod is the rotation radius of the fruit output mechanism 4 driven by the lower support rod 102 to swing. The length of the upper section 104 is smaller than the straight-line distance between the two ends of the lower support rod 102, which means that the rotation radius of the fruit output mechanism driven by the upper section 104 is smaller than the rotation radius of the fruit output mechanism driven by the lower support rod 102, so that the swing amplitude of the rear end of the fruit output mechanism is smaller than the swing amplitude of the front end of the fruit output mechanism, which is beneficial to reducing the slope of the fruit output mechanism tilting forward, reducing the height difference between the rear end and the front end of the fruit output mechanism, and reducing the probability of the fruit rolling down due to gravity during the process of outputting the fruit to the rear end, thereby improving the fruit output efficiency and the harvest rate.

[0063] Among them, the output chain scraper assembly 12 includes a conveyor chain 19 installed in the fruit output rack 11 and transmission-connected to the main gearbox 8, a chain cross bar 20 evenly spaced and fixed on the chain 19, and a scraper 21 hinged on the chain cross bar 20. The fruit in the collecting umbrella mechanism 3 is transported from the front end of the fruit output rack 11 to the rear end and output as the scraper 21 moves. Four scrapers 21 arranged side by side are hinged on each chain cross bar 20 through a spring hinge. The scraper 21 swings as the gravity of the fruit is greater than the elastic force of the spring hinge. The conveyor chain 19 moves in the fruit output rack 11 with the power output by the main gearbox 8. The chain cross bar 20 is laterally fixed on the conveyor chain 19 and evenly spaced along the conveyor chain 19. The scraper 21 is hinged on the chain cross bar 20 through a spring hinge. As the conveyor chain 19 moves, the fruit in the collecting umbrella mechanism 3 is pushed backward, realizing the automatic output and collection of vibration-picked fruit. When the downward force of the fruit on the scraper is greater than the elastic force of the spring hinge, the scraper will swing downward, releasing the fruit and rolling it downward to avoid too much fruit piling up on the scraper, causing the conveyor chain 19 to fail to operate normally. When a lot of fruit is piled on the scraper, the scraper automatically lowers and releases the fruit to avoid the conveyor chain 19 from being stuck, reducing the fruit output blocking rate, ensuring the normal operation of the conveyor chain 19, and improving the fruit output efficiency.

[0064] Among them, the vibrator 13 is suspended below the fruit output mechanism 4 by a flexible chain and is located between the power mechanism and the fruit output mechanism 4. The vibrator 13 is flexibly connected to the fruit output mechanism 4. The flexible connection makes it convenient for the vibrator 13 to rise and fall with the swing of the fruit output mechanism 4 and then maintain a transmission connection with the main gearbox. The clamping claw assembly 14 includes a clamping claw fixing frame 22 fixed to the vibrator 13 and extending to the front end of the fruit output mechanism, a clamping claw 23 hinged on the clamping claw fixing frame 22, and an opening and closing cylinder 24 connected to the clamping claw 23 and obtaining power from the hydraulic system. There are two clamping claws 23 and they are respectively hinged on the left and right sides of the clamping claw fixing frame 22. The two ends of the opening and closing cylinder 24 are respectively connected to the clamping claws 23. The two clamping claws 23 open or close with the extension and contraction of the opening and closing cylinder 24. The clamping claw 23 is covered with a rubber sleeve, and a rubber block 25 located between the two clamping claws 23 is fixed on the clamping claw fixing frame 22. The opening and closing oil cylinder 24 is used to open or close the clamping jaws 23. Through the expansion and contraction of the opening and closing oil cylinder 24, the two clamping jaws 23 can clamp tree trunks of different diameters. The rubber sleeve and rubber block 25 are used to protect the tree trunk from damage.

[0065] The connection end of the clamp 23 has a double-layer connector 231, the upper layer of the double-layer connector 231 is hinged to the opening and closing cylinder 24, and the lower layer is hinged to the clamp fixing frame 22, and the upper layer hinge position is located outside the lower layer hinge position. Figure 8As shown, the hinged position between the upper layer of the double-layer connecting head 231 and the opening and closing oil cylinder 24 is located outside the hinged position between the lower layer and the clamping claw fixing frame 22. When the opening and closing oil cylinder 24 is fully extended, the two clamping claws are in a retracted state. When the opening and closing oil cylinder 24 is shortened, it will pull the double-layer connecting head 231 on one side to rotate around the hinged position with its lower layer. Limited by the hinged position of the lower layer, the opening and closing oil cylinder 24 can only pull the double-layer connecting head 231 on this side to rotate a certain angle, so that the corresponding clamping claw 23 is opened. When the oil cylinder continues to shorten, the double-layer connecting head 231 on this side can no longer rotate, and the oil cylinder 24 The reaction force of the internal structure of the cylinder will cause the other side of the cylinder to start moving, causing the cylinder to continue to shorten, and drive the double-layer connecting head 231 on the other side to rotate, so that the corresponding clamping jaws 23 on the other side will open, until the double-layer connecting head 231 on this side can no longer rotate and the opening and closing cylinder 24 can no longer shorten. Both clamping jaws are open, and when the tree trunk needs to be clamped, it is only necessary to extend the opening and closing cylinder to make the clamping jaws relatively close to each other by a certain distance. The opening and closing of the clamping jaws can be achieved by controlling the opening and closing cylinder 24. The control of the clamping jaws is simple and the clamping force is reliable, which can ensure the effectiveness of vibration picking.

The collecting umbrella assembly 16 is connected to the umbrella rib sprocket assembly 28. The crank rocker assembly 27 drives the umbrella rib sprocket assembly 28 to move as the electric push rods 26 extend and retract, and the collecting umbrella assembly 16 opens or closes as the umbrella rib sprocket assembly 28 moves.

[0067] The crank rocker assembly 27 includes a rocker 271 hinged to the telescopic end of the electric push rod 26, a connecting rod 272 hinged to the telescopic end of the electric push rod 26, and a crank 273 hinged to the connecting rod 272 and shorter than the rocker 271.

The crank shaft 274 is rotatably mounted in the U-shaped centering frame 25 in the vertical direction. The rocker shaft 275 is vertically fixed in the U-shaped centering frame 25 and the free end of the rocker 271 is rotatably sleeved on the rocker shaft 275.

[0068] The collection umbrella assembly 16 includes active ribs 29 rotatably mounted on a U-shaped centering frame 25 and extending forward, and passive ribs 30 located behind the active ribs 29. A plurality of passive ribs 30 are rotatably mounted on the U-shaped centering frame 25 and extending forward. The active ribs 29 are connected to adjacent passive ribs 30 , and adjacent passive ribs 30 are connected to each other via fan-shaped umbrella fabrics 31.

[0069] The rib sprocket assembly 28 includes a driving sprocket 281 fixed to the crankshaft 274, a driven sprocket 282 coaxially fixed to the lower end of the active rib 29, and a roller chain 283 connecting the driving sprocket 281 and the driven sprocket 282. The driving sprocket 281 rotates with the crankshaft 274, thereby driving the driven sprocket 282 to rotate, thereby causing the active rib 29 to rotate synchronously.

[0070] The umbrella cloth 31 is connected to the active umbrella ribs 29 and the passive umbrella ribs 30 by Velcro. The edge of the umbrella cloth 31 has magnetic blocks that can attract the active umbrella ribs 29 and the passive umbrella ribs 30 to ensure the reliability of the connection between the umbrella cloth 31 and the umbrella ribs.

The two electric push rods 26 are respectively connected to a group of crank rocker assemblies 27, and the two groups of crank rocker assemblies 27 are respectively connected to a group of umbrella rib sprocket assemblies 28. The two groups of umbrella rib sprocket assemblies 28 are respectively connected to a group of collecting umbrella assemblies 16. The electric push rods 26 are extended to drive the crank remote rod assembly 27 to move, so that the umbrella rib sprocket assembly 28 moves to drive the active umbrella rib 29 in the collecting umbrella assembly 16 to move, and the passive umbrella rib 30 moves subsequently with the pulling of the umbrella cloth, forming the synchronous opening or folding of the two groups of collecting umbrella assemblies 16. When opened, a complete collecting umbrella is formed. After folding, they move to the left and right respectively. The two sides are folded together to facilitate the movement of the harvester. Since the length of the crank 273 in the crank rocker assembly 27 is smaller than the length of the rocker 271, the electric push rod 26 pushes the rocker 271 to rotate a small angle to enable the crank 273 to obtain a larger rotation angle, thereby increasing the rotation angle of the crank shaft 274 and the active sprocket 281 to obtain a larger rotation angle, so as to increase the working stroke of the roller chain 283 within a limited space, that is, to increase the rotation angle of the active umbrella rib, to ensure that the electric push rod 26 can fully open the collecting umbrella assembly 16 within the stroke range, and the two collecting umbrella assemblies 16 are spliced ​​to form a complete collecting umbrella, thereby improving the opening and closing reliability and efficiency of the collecting umbrella.

[0077] The main gearbox 8 has multiple gears including forward, reverse, parking, vibration and conveying. The final stage of the forward and reverse gears is a worm gear transmission, which utilizes the self-locking characteristics of the worm gear to avoid the danger of the harvester body sliding backward due to inertia when harvesting on a slope. It can prevent slipping when the power source is disconnected, such as when driving, parking, neutral, clutch disengaged, gear sliding, etc. The use of the differential 36 can eliminate the driving instability caused by the different wheel speeds on both sides when the car turns, thereby improving the stability and safety of the harvester operating on a slope.

[0078] The transmission principle of each gear of the main gearbox 8 is as follows:

[0079] (1) Forward gear

The worm wheel 35 then transmits power to the running wheels through the differential 36.

[0083] (3) Vibration gear

[0084] After the console 5 controls the clutch 70 to brake, the first gear pull rod 51 shifts the first gear shift fork 41 to the vibration gear, so that the first gear double gear set 41 engages with the vibration shaft gear 45. The console 5 controls the clutch 70 to engage, and the input shaft drives the first gear double gear set 39 to rotate. The vibration shaft gear 45 drives the vibration shaft 38 to rotate, so that the first bevel gear 46 rotates.
