[0039] See Figures 1 to 10 The mountain walnut harvester provided in this application includes a walking component 1, a dragging component 2, and a lifting component 3. The lifting component 3 includes a lifting platform connected to the walking component 1 at one end via a support shaft 303 and a first drive mechanism for driving the lifting platform to rotate around the support shaft 303. The dragging component 2 includes a winch base 215 slidably connected to the lifting platform in a direction perpendicular to the support shaft 303, a traction rope 223 connected to the winch base 215, and a second drive mechanism for driving the winch base 215 to reciprocate.
[0040] The traveling assembly 1 is located below the entire harvester and provides power to move the dragging assembly 2 and the lifting assembly 3. The dragging assembly 2 and the lifting assembly 3 are mounted above the traveling assembly 1. The lifting assembly 3 includes a lifting platform and a first drive mechanism. One end of the lifting platform is rotatably connected to the top of the traveling assembly 1 via a horizontally arranged support shaft 303, so that the lifting platform can rotate around the support shaft 303. The first drive mechanism is connected between the traveling assembly 1 and the lifting platform and provides power to drive the lifting platform to rotate around the support shaft 303, thereby adjusting the tilt angle of the lifting platform. The towing assembly 2 includes a winch base 215, a traction rope 223, and a second drive mechanism. The winch base 215 is slidably connected to the lifting platform. The second drive mechanism can be connected between the winch base 215 and the walking assembly 1 or between the winch base 215 and the lifting platform, and is used to drive the winch base 215 to reciprocate in a direction perpendicular to the support shaft 303. One end of the traction rope 223 is connected to the winch base 215, and the other end of the traction rope 223 is used to connect to the walnut tree during harvesting operations.
[0041] The walnut harvester provided in this application embodiment is used for harvesting walnuts. The specific harvesting process is as follows: First, the walking component 1 is controlled to move in the harvesting area. When it moves to the predetermined position, the traction rope 223 is connected to the walnut tree. The first drive mechanism is controlled to drive the lifting platform to rotate around the support shaft 303 until the moving direction of the winch base 215 is consistent with the pulling direction of the traction rope 223, thus tightening the traction rope 223. Then, the second drive mechanism is controlled to drive the winch base 215 to move back and forth. The winch base 215 drives the traction rope 223 to pull the walnut tree, causing the walnut tree to sway and causing the mature walnuts to fall from the tree, thus achieving walnut harvesting.
[0042] The walnut harvester provided in this application embodiment can rapidly move the towing component 2 and lifting component 3 within the harvesting area via the walking component 1. A second drive mechanism drives the winch base 215 to reciprocate, and the winch base 215, through the traction rope 223, causes the walnut trees to sway, thus harvesting the walnuts. A first drive mechanism drives the lifting platform to rotate around the support shaft 303, adjusting the tilt angle of the lifting platform so that the movement direction of the winch base 215 is consistent with the tension direction of the traction rope 223. This not only reduces the swaying of the traction rope 223 under stress but also effectively transmits the tension of the traction rope to the walnut trees, making the swaying more powerful and improving harvesting efficiency. In complex terrains such as mountains, the traction rope 223 can be flexibly connected to different walnut trees, allowing the walking component 1 to operate from a fixed position without having to move to each tree, thus improving work efficiency. Therefore, this application can operate flexibly in complex terrains such as mountains, solving the problem that existing harvesting devices cannot approach walnut trees for harvesting due to terrain limitations.
[0043] The first drive mechanism may include linear actuators such as cylinders, hydraulic cylinders, and electric push rods. The two ends of the linear actuators are respectively hinged to the lifting platform and the traveling assembly 1. By controlling the extension and retraction of the linear actuators, the lifting platform is rotated around the support shaft 303, thereby achieving the purpose of adjusting the tilt angle of the lifting platform.
[0044] In some embodiments, see Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 The first drive mechanism includes a fixed frame 301, a lead screw 309, a lead screw slider 311, and a connecting rod 310. The fixed frame 301 is connected to the traveling assembly 1. The lead screw 309 is mounted on the fixed frame 301 perpendicular to the support shaft 303 and rotatably around its own axis. The lead screw slider 311 is threadedly connected to the lead screw 309. One end of the connecting rod 310 is hinged to the lead screw slider 311, and the other end of the connecting rod 310 is hinged to the lifting platform. In use, rotating the lead screw 309 pushes the lead screw slider 311 to move along the lead screw 309. The lead screw slider 311 then drives the lifting platform to rotate around the support shaft 303 via the connecting rod 310, thereby adjusting the tilt angle of the lifting platform. The lead screw structure allows for more precise control of the lifting platform's lifting angle, enabling the entire lifting platform to rotate to different angles.
[0045] For example, the fixed frame 301 is a frame structure welded from crossbars and longitudinal bars, horizontally set and fixed to the top of the traveling assembly 1; support ears 302 are respectively provided on both sides of one end of the fixed frame 301, and the support ears 302 are fixedly connected to the fixed frame 301 by a fifth bolt 317; two second bearing seats 308 are connected to the fixed frame 301 by a sixth bolt 318, and the two second bearing seats 308 are spaced apart along the axial direction of the lead screw 309; the lead screw 309 is connected to the two second bearing seats 308 so that the lead screw 309 can rotate around its own axis; in order to facilitate the rotation of the lead screw 309, a lead screw handle 315 is connected to one end of the lead screw 309; the lifting platform includes two The system includes parallel longitudinal support rods 305 and several transverse support rods 306 fixed between the two longitudinal support rods 305. One end of each of the two longitudinal support rods 305 is rotatably connected to two support ears 302 via a support shaft 303. Support blocks 307 are welded to the middle of each of the two longitudinal support rods 305. There are two connecting rods 310, one end of which is hinged to the lead screw slider 311, and the other end of which is hinged to the two support blocks 307. Lifting platform limiting blocks 316 extending upward are welded to both sides of the other end of the fixing frame 301 to limit the minimum lifting angle of the lifting platform and prevent the lifting platform from interfering with the operation of the lead screw 309.
[0046] The second drive mechanism may include a cylinder, which, through the extension and retraction of the cylinder, drives the winch base 215 to reciprocate on the lifting platform.
[0047] In some embodiments, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The second drive mechanism includes a transmission assembly, a drive wheel 208, and a connecting rod 210. The drive wheel 208 is coaxially arranged with the support shaft 303 and rotatably mounted on the walking assembly 1. The power output shaft of the walking assembly 1 is connected to the drive wheel 208 through the transmission assembly and is used to drive the drive wheel 208 to rotate. One end of the connecting rod 210 is hinged to the drive wheel 208, and the other end of the connecting rod 210 is hinged to the winch base 215.
[0048] The working principle of the second drive mechanism is as follows: The power output shaft of the walking assembly 1 is rotated to transmit power to the drive wheel 208 via the transmission assembly, causing the drive wheel 208 to rotate. The drive wheel 208 then drives the connecting rod 210 to rotate around its center, thereby driving the winch base 215 to reciprocate on the lifting platform. By coaxially aligning the drive wheel 208 with the support shaft 303, the position of the drive wheel 208 remains unchanged when adjusting the tilt angle of the lifting platform.
[0049] For example, the drive wheels 208 include two coaxially spaced wheels, each with a drive wheel axle fixed to its outer side. The two drive wheel axles are connected to the traveling assembly 1 via bearing seats, allowing the drive wheels 208 to rotate around the drive wheel axles. The two drive wheel axles are coaxially arranged with two support shafts 303. One end of the connecting rod 210 is positioned between the two drive wheels 208 and rotatably connected to them via a first connecting pin 209, allowing the connecting rod 210 to rotate around the first connecting pin 209, thus ensuring the rotational speed of the connecting rod 210. At least two pin holes are radially spaced on each drive wheel 208 for the first connecting pin 209 to pass through. By inserting the first connecting pin 209 into different pin holes, the linear speed of the connecting rod 210 can be adjusted, thereby adjusting the reciprocating frequency of the winch base 215, achieving the purpose of controlling the shaking force of the traction rope 223 on the walnut tree, adapting to walnut trees of different sizes and maturity levels.
[0050] The transmission assembly is used to realize the power transmission between the power output shaft of the walking assembly 1 and the drive wheel shaft of the drive wheel 208, and it may include belt drive mechanism, chain drive mechanism and gear drive mechanism, etc.
[0051] In some embodiments, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The transmission assembly includes a reducer 204, a first belt mechanism, and a second belt mechanism. The reducer 204 is connected to the walking assembly 1. The power output shaft of the walking assembly 1 is connected to the input shaft of the reducer 204 via the first belt mechanism. The output shaft of the reducer 204 is connected to the drive wheel 208 via the second belt mechanism.
[0052] In use, the power output shaft of the walking assembly 1 transmits power to the reducer 204 via the first belt mechanism. The reducer then transmits power to the drive wheel 208 via the second belt mechanism, thereby driving the drive wheel 208 to rotate. Through the cooperation of the reducer and the belt mechanism, not only can the power transmission be more precise, but the rotational speed of the drive wheel 208 can also be controlled within a reasonable range, preventing the drive wheel 208 from rotating too fast.
[0053] For example, the first belt mechanism may include a first pulley 201, a first belt 202, and a second pulley 203; the first pulley 201 is fixed to the power output shaft of the traveling assembly 1, and the second pulley 203 is fixed to the input shaft of the reducer 204. The first pulley 201 and the second pulley 203 are connected by a first belt 202 sleeved on both of them, for transmitting the power output from the traveling assembly 1 to the reducer 204. The second belt mechanism may include a third pulley 205, a second belt 206, and a fourth pulley 207; the third pulley 205 is fixed to the output shaft of the reducer 204, and the fourth pulley 207 is fixed to the drive wheel shaft. The third pulley 205 and the fourth pulley 207 are connected by a second belt 206 sleeved on both of them, for transmitting the power output from the reducer 204 to the drive wheel 208.
[0054] In some embodiments, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The connecting rod 210 is connected to the winch base 215 through the transition slider 212. The transition slider 212 is slidably connected to the lifting platform, and its sliding direction is parallel to the sliding direction of the winch base 215.
[0055] In use, the connecting rod 210 first drives the transition slider 212 to move back and forth, and the transition slider 212 then drives the winch base 215 to move back and forth. By setting the transition slider 212, the direction of the pulling force of the transition slider 212 on the winch base 215 can be made consistent with the direction of movement of the winch base 215, thereby reducing the swaying or swinging of the winch base 215 when under force, and effectively transferring the pulling force of the winch base 215 to the traction rope 223.
[0056] For example, the end of the connecting rod 210 is movably connected to the transition slider 212 via the second connecting pin 211, so that the connecting rod 210 can rotate around the second connecting pin 211, and the transition slider 212 is connected to the winch base 215 via the third connecting pin.
[0057] In some embodiments, see Figure 4 , Figure 5 , Figure 6 The dragging assembly 2 also includes a transition groove 213 connected to the lifting platform, and a transition slider 212 slidably engages in the transition groove 213. The transition slider 212 can slide back and forth in a straight line within the transition groove 213. In order to reduce the friction between the two, the transition groove 213 is provided with balls that roll in cooperation with the transition slider 212.
[0058] In some embodiments, see Figure 4 , Figure 5 , Figure 6 The dragging assembly 2 also includes a winch 217 rotatably mounted on a winch base 215 and a motor that drives the winch 217 to rotate. One end of the traction rope 223 is connected to the winch 217 and wound around the winch 217.
[0059] For example, a mounting bracket is fixed to the winch base 215 by a second bolt 218, and the winch 217 is rotatably mounted on the mounting bracket via a winch shaft so that the winch 217 can rotate around the winch shaft. The motor is fixed on the mounting bracket, and the output shaft of the motor is connected to the winch shaft for driving the winch shaft to rotate the winch 217.
[0060] In use, the winch 217 is driven by a motor to rotate in both directions, which can quickly achieve the winding and release of the traction rope 223. After the traction rope 223 is connected to the walnut tree, the winch 217 can also be driven by a motor to rotate, so as to wind the traction rope 223 onto the winch 217 and achieve rapid tightening of the traction rope 223. This can reduce the preparation time during harvesting operations, improve harvesting efficiency, and reduce the labor intensity of workers.
[0061] In some embodiments, see Figure 4 , Figure 5 , Figure 6 The dragging assembly 2 also includes a winch groove 214 connected to the lifting platform, and a winch base 215 slidably fitted in the winch groove 214. The winch base 215 can slide back and forth in a straight line within the winch groove 214. To reduce the frictional resistance between the two, a number of ball bearings 219 are provided between the winch groove 214 and the winch base 215.
[0062] For example, see Figure 7 , Figure 8 The bottom of the inner groove of the winch trough 214 is provided with multiple mounting grooves extending along the sliding direction. Several balls 219 are placed in the mounting grooves. A third bolt 220 is fixed to one end of the mounting groove to limit the position of the balls 219. The top of the balls 219 protrudes two millimeters from the mounting groove, which can ensure that the winch base 215 slides smoothly in the winch trough 214. In order to further reduce the friction between the winch base 215 and the winch trough 214, positioning grooves are provided on both sides of the inner groove of the winch trough 214. The top of both sides of the winch trough 214 is provided with mounting holes extending downward and communicating with the positioning grooves. There are multiple mounting holes, which are spaced apart along the sliding direction of the winch base 215. A bearing shaft 222 is provided in the mounting hole. A first bearing 221 for rolling cooperation with the winch base 215 is installed on the bearing shaft 222. A first bolt 216 for pressing and fixing the bearing shaft 222 is connected to the upper thread end of the mounting hole. This further improves the smoothness of the winch base 215 within the winch groove 214.
[0063] The mobility assembly 1 may include an electric vehicle or a tractor, wherein the electric vehicle is powered by an electric motor, and the tractor is powered by an internal combustion engine. See also, in some embodiments. Figure 1 , Figure 2 The traveling assembly 1 includes a tracked vehicle. A tracked vehicle is a vehicle that uses tracks as its walking mechanism; it has high traction and excellent climbing and ground grip, enabling it to work effectively on steep or soft ground. Tracked vehicles can be powered by diesel engines, providing more powerful horsepower.
