Description

Technical Field

[0001] This utility model relates to agricultural and forestry equipment, and more particularly to a single-wheel lifting and transporting vehicle. Background Technology

[0002] During the fruit harvest season, in most cases, fruit picking is still done by traditional manual labor. After picking the fruit from the tree, the fruit farmers put it into net baskets. Once the baskets are full, they carry the baskets a distance and place them on the transport vehicles.

[0003] Existing technology discloses a lifting handcart for raising and lowering goods, including a frame, a drive mechanism, and a carrying platform. The carrying platform is slidably connected to the frame, and the drive mechanism can drive the carrying platform to slide up and down. In use, goods are moved onto the carrying platform, then transported to a designated location, and then the carrying platform lifts the goods to the height of the carriage before unloading them. Although this type of lifting handcart can save manpower and facilitate freight transportation, it has the following problems: First, this two-wheeled cart is more suitable for traveling on flat roads. However, for orchards with dense fruit trees, the road conditions are poor, and two-wheeled transportation... The cart is difficult to maintain balance and stability in the narrow, rugged terrain of the orchard, and is prone to tilting. On potholes, the wheels on both sides wobble greatly, which can easily damage the fruit. When going down steep slopes, the resistance of the two wheels is high, requiring more force to push. Due to the limited width of the two wheels, it is difficult to pass through some narrow roads. Secondly, although this type of cart can transport and lift goods to a certain height, it requires human assistance to lift the goods onto the loading platform and unload them from the platform, which is time-consuming and laborious. Although the existing wheelbarrow can travel on narrow roads, it also requires human labor to load the fruit baskets onto the cart, and it cannot load and unload the fruit baskets.

Detailed Implementation

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0041] Example 1:

[0042] like Figures 1 to 4As shown, a single-wheel lifting transport vehicle includes a vehicle body. The front and rear sides of the vehicle body are respectively provided with a traveling wheel 1 and a hanging basket structure 2. The traveling wheel 1 is connected to the middle of the bottom end of the vehicle body. The hanging basket structure 2 is slidably connected to the vehicle body via a lifting sliding frame 3. The left and right sides of the hanging basket structure 2 are provided with downward support legs 4, which are connected to the bottom end of the vehicle body. The vehicle body is also provided with a two-way handrail 5. One end of the two-way handrail 5 is connected to the vehicle body so that the two-way handrail 5 can rotate and swing between the side of the traveling wheel 1 and the side of the hanging basket structure 2.

[0043] The walking wheel 1 is a single wheel, which works in conjunction with the two supporting legs 4 to achieve the effect of a single-wheeled cart. When moving the net basket, the two-way handrail 5 is on one side of the hanging basket structure 2 and locked. When the handrail is lifted, the supporting legs naturally rise with the cart body. The single walking wheel 1 and the two handrails work together to maintain balance on rugged terrain. It is suitable for uneven and narrow roads in orchards. When lifting the net basket, the two-way handrail 5 is lowered, and the supporting legs 4 work with the walking wheel 1 to ensure the cart body is upright and balanced.

[0044] The angle of the bidirectional handrail 5 is adjustable to accommodate the needs of carrying and lifting the wire mesh basket. When carrying the wire mesh basket, the bidirectional handrail 5 is rotated to the side of the hanging basket structure 2 to facilitate the movement of the transport vehicle. When lifting the wire mesh basket, the bidirectional handrail 5 is rotated to the side of the traveling wheel 1 to facilitate the lifting of the wire mesh basket into the vehicle.

[0045] The working principle of this embodiment is as follows:

[0046] Before transporting, place the basket filled with fruit on the ground. Rotate and lock the double-handle 5 to one side of the basket hanging structure 2. At this time, the side of the driving wheel 1 forms the front of the vehicle body, and the user stands at the rear of the vehicle body. The user pulls the transport vehicle backward so that the basket hanging structure 2 is aligned with the basket, and the basket hanging structure 2 is located below the top rib ring of the basket. Then, lift the handle upward so that the basket hanging structure 2 lifts the basket. Push the transport vehicle forward. See the attached diagram for the desired state. Figure 3 At this time, the transport vehicle is similar to a traditional single-wheeled cart. The use of a single wheel makes it suitable for walking in narrow spaces and rugged areas. The balance of the vehicle can be maintained by controlling the left and right handles. In addition, the net basket filled with fruit is located behind the walking wheel 1, that is, the center of gravity of the entire transport vehicle is biased to the rear, which makes it easier for the user to maintain balance and prevents it from tipping over.

[0047] After the basket is moved to the designated location, lower the two-way handrail 5. The traveling wheels 1 and support legs 4 work together to support the ground and maintain the balance of the vehicle. Then rotate and lock the two-way handrail 5 to one side of the traveling wheels 1. See the status below. Figure 4At this point, one side of the wire mesh basket serves as the front of the vehicle body, and the user stands at the rear of the vehicle body. The user adjusts the distance between the vehicle body and the carriage. Once the distance is adjusted, the wire mesh basket can be lifted by the lifting and sliding frame 3. When the height of the wire mesh basket exceeds that of the carriage, the vehicle body is moved closer to the carriage so that the wire mesh basket is directly above the carriage. Then, the lifting and sliding frame 3 is lowered so that the wire mesh basket can be placed directly on the carriage, and the hanging structure 2 is lower than the height of the wire mesh basket rib ring. The hook is then released, and the transport vehicle is moved backward to complete the automatic unloading of the wire mesh basket.

[0048] The bottom end of the support leg 4 is equipped with a support wheel 6, which serves both a supporting function and a walking function. When walking on a flat road, adjusting the angle of the handrail allows the support wheel 6 to contact the ground for walking, making it easier for the user. The support wheel 6 can be a swivel caster.

[0049] See Figure 5 and Figure 6 The vehicle body is provided with a connecting seat, and one end of the bidirectional handrail 5 is rotatably connected to the connecting seat. An angle locking mechanism is provided between the connecting seat and the bidirectional handrail. In this embodiment, the bidirectional handrail 5 has a U-shaped structure, and the middle part of the U-shaped structure is rotatably connected to the connecting seat. Of course, the bidirectional handrail 5 is not limited to a U-shape; other similar U-shaped handrails are also possible.

[0050] See Figures 5 to 7 The angle locking mechanism 7 includes a forward ratchet 71 and a reverse ratchet 72 fixed to the outside of the bidirectional handrail 5. A forward pawl 73 and a reverse pawl 74, respectively cooperating with the forward ratchet 71 and the reverse ratchet 72, are rotatably connected to the connecting seat. The forward pawl 73 is engaged with the forward ratchet 71 by a torsion spring, and the reverse pawl 74 is engaged with the reverse ratchet 72 by a torsion spring. An angle control handle is installed at the end of the bidirectional handrail 5. A pull cable one for controlling the forward pawl 73 to release the forward ratchet 71 and a pull cable two for controlling the reverse pawl 74 to release the reverse ratchet 72 are connected to the angle control handle. The forward ratchet 71 and the reverse ratchet 72 are used to control the forward and reverse rotation of the bidirectional handrail, respectively.

[0051] When the angle control handle is pressed, the forward pawl 73 is pulled by the pull cable, causing the forward pawl 73 to disengage from the forward ratchet 71. At this time, the forward ratchet 71 is released, and the bidirectional handle 5 can rotate in the forward direction. When the desired angle is reached, the angle control handle is released, and the forward pawl 73, under the action of the torsion spring, will press against the forward ratchet 71, locking the forward ratchet 71. (See attached diagram for details.) Figure 7The bidirectional handrail 5 is locked. When the angle control handle is pressed, the reverse pawl 74 is pulled by the pull cable 2, causing the reverse pawl 74 to disengage from the reverse ratchet 72. At this time, the reverse ratchet 72 is released, and the bidirectional handrail 5 can rotate in the opposite direction. When the desired angle is reached, the angle control handle is released, and the forward pawl 73 will press against the forward ratchet 71 under the action of the torsion spring, locking the forward ratchet 71 and thus locking the bidirectional handrail 5.

[0052] See Figure 1 and Figure 2 The vehicle body includes a frame 8 and a telescopic column 9. The telescopic column 9 includes a fixed column 91 and a lifting column 92 slidably connected to the fixed column 91. A guide wheel is installed at the top of the fixed column 91. An electric winch 93 is provided on the vehicle body, and a rope is wound around the electric winch 93. The free end of the rope passes around the guide wheel and connects to the lower part of the lifting column 92. A guide wheel 2 is installed at the top of the lifting column 92, and a rope 2 is wound around the guide wheel 2. One end of the rope 2 is connected to the top of the fixed column 91, and the other end of the rope 2 is connected to the lifting sliding frame 3. A guide groove 1 is provided on the side of the fixed column 91. A sliding wheel assembly 1 that slides vertically along the guide groove 1 is arranged on the lower side of the lifting column 92. A guide groove 2 is provided on the side of the lifting column 92, and a sliding wheel assembly 2 that slides vertically along the guide groove 2 is arranged on the lifting connecting frame. When the electric winch 93 operates, it pulls the first rope to tighten, pulling the lifting column 92 upward. The lifting column 92 rises along the guide groove of the fixed column 91 via the first set of sliding wheels. As the lifting column 92 rises, it drives the second guide wheel upward, and the second rope pulls the lifting sliding frame 3 upward along the guide groove of the lifting column 92 via the second set of sliding wheels. This causes the upper hook to move upward, lifting the net basket off the ground. Then, the transport vehicle is pushed to the vicinity of the transport vehicle's cargo compartment. The electric winch 93 operates again, raising the net basket until its bottom is higher than the height of the transport vehicle's cargo compartment. Then, the electric winch 93 reverses direction. During this reverse movement, the rope is released, and under the weight of the basket hanging structure 2 and the basket itself, the lifting sliding frame 3 slides downwards along the lifting column 92. The lifting column 92 then slides downwards along the fixed column 91, causing the upper hook to descend and lower the net basket onto the transport vehicle's cargo compartment. The upper hook is lowered below the net basket's reinforcing ribs, and then the transport vehicle moves away. The specific structure of the telescopic column is prior art and is not shown in the accompanying drawings.

[0053] The hanging basket structure 2 includes a fruit basket hook 21 and a fruit basket support bar 22 located below the fruit basket hook 21. The fruit basket hook 21 and the fruit basket support bar 22 are correspondingly matched. The fruit basket hook 21 is an upper hook head connected to the lifting and sliding frame 3. The rib ring of the net basket is hooked on the upper hook head. In this embodiment, the upper hook head is a V-shaped hook. The fruit basket support bar 22 is an arc-shaped support bar that matches the shape of the round net basket. The arc-shaped support bar is used to support the round net basket and prevent the net basket from floating and swaying during transportation. The middle part of the arc-shaped support bar is fixed to the bottom end of the lifting and sliding frame 3 or connected to the bottom end of the lifting and sliding frame 3 by bolts.

[0054] The traveling wheel is a drive wheel, and a drive motor is installed on the traveling wheel 1. A control switch or handle for controlling the drive motor is installed at the end of the bidirectional handrail 5. In this case, the traveling wheel 1 is a drive wheel. Of course, the traveling wheel 1 can also be a non-drive wheel.

[0055] The vehicle body is also equipped with a power module, which can provide power to the electric winch 93 to control the raising and lowering of the basket. At the same time, the power module can also provide power for the movement of the wheels.

[0056] The wheelbarrow of this application is not limited to the use of round or square baskets, but is also applicable to plastic turnover boxes.

[0057] Example 2:

[0058] This embodiment is basically the same in structure as Embodiment 1, the main difference being the structure of the angle locking mechanism. See also Figure 8 The angle locking mechanism 7 includes a turntable 75 fixed to the outside of the bidirectional handrail 5. The surface of the turntable 75 is provided with a plurality of limiting grooves 76. A spring pin 77 is provided between the turntable 75 and the connecting seat. One end of the spring pin 77 is fixed to the connecting seat, and the other end of the spring pin 77 is engaged in the limiting groove 76. An angle control handle is installed at the end of the bidirectional handrail 5. A pull line is connected to the angle control handle to control the spring pin 77 to disengage from the limiting groove 76.

[0059] When the angle control handle is pressed, the spring pin 77 is pulled by the pull cable, causing the spring pin 77 to disengage from the limiting groove 76. At this time, the bidirectional handrail 5 can be rotated. When the desired angle is reached, the angle control handle is released, and the spring pin 77 will be pressed into the limiting groove 76 under the action of the spring, locking the turntable 75 and thus locking the bidirectional handrail 5.

[0060] Example 3:

[0061] This embodiment is basically the same in structure as Embodiment 1, the main difference being the structure of the angle locking mechanism. See also Figure 9 The angle locking mechanism includes a gear plate 78 fixed to the outside of the bidirectional handrail 5. A locking block 79 is provided on the connecting seat. The locking block 79 is provided with limiting teeth that mesh with the outer periphery of the gear plate 78. One end of the locking block 79 is rotatably connected to the connecting seat. A spring is provided between the other end of the locking block 79 and the connecting seat to press the locking block 79 against the gear plate 78. An angle control handle is installed at the end of the bidirectional handrail 5. A pull cable is connected to the angle control handle to control the locking block 79 to disengage from the gear plate 78.

[0062] When the angle control handle is pressed, the locking block 79 is pulled by the pull cable, causing the locking block 79 to move away from the gear plate 78. The locking block 79 and the gear plate 78 are disengaged. At this time, the bidirectional handrail 5 can be rotated. When the desired angle is reached, the angle control handle is released. Under the action of the spring, the locking block 79 approaches the gear plate 78 and engages with the gear plate 78, locking the gear plate 78 and thus locking the bidirectional handrail 5.

[0063] Example 4:

[0064] This embodiment has a structure that is basically the same as that of Embodiment 1, the main difference being the structure of the fruit basket handle 22.

[0065] See Figure 10 The fruit basket support rod 22 includes a fixed connecting rod connected to the bottom end of the lifting and sliding frame 3. The fixed connecting rod is fixed to the bottom end of the lifting and sliding frame 3 or connected to the bottom end of the lifting and sliding frame 3 by bolts. A horizontal support rod 22a is fixedly installed on the outer end of the fixed connecting rod. Side support rods 22b are respectively connected to the left and right sides of the horizontal support rod 22a. The side support rods 22b can be fixedly installed at the ends of the horizontal support rod 22a by welding. The width between the two side support rods 22b is not adjustable. Of course, the width of the side support rods 22b can also be adjusted through the adjustment holes provided laterally on the horizontal support rod 22a.

[0066] The horizontal support bar 22a and the side support bar 22b are used together to support both round and square baskets. When supporting a square basket, the back of the basket can rest against the horizontal support bar 22a, and the two sides of the basket can rest against the side support bar 22b respectively. When supporting a round basket, the horizontal support bar 22a and the side support bar 22b can make contact with the round basket at three points, which can also achieve the effect of supporting the basket.

[0067] Example 5:

[0068] This embodiment has a basically the same structure as Embodiment 1, the main difference being the structure of the fruit basket hook 21.

[0069] See Figure 11 and Figure 12 The fruit basket hook 21 includes a mounting bracket fixed to the lifting frame. Both ends of the mounting bracket have outwardly extending connecting rods 29. The inner sides of each connecting rod 29 are respectively provided with a basket hook 28. The inner end of the basket hook 28 extends to the inner side of the connecting rod 29 and can hook the side of the basket. The outer end of the basket hook 28 is rotatably mounted on the connecting rod 29 via a pivot. The basket hook 28 can swing forward and backward around the pivot. The basket hook 28 is provided with a reset component that allows it to automatically return to the center position after swinging forward and backward. The reset component includes a tension spring, which is located on the rear side of the basket hook 28. One end of the tension spring is connected to the connecting rod 29, and the other end is connected to the basket hook 28. The reset component can also be a torsion spring. See also Figure 11 The fruit basket handle 22 is a U-shaped handle, see [link / reference]. Figure 12 The handle 22 for the medium-sized fruit basket is an arc-shaped handle. See also... Figure 13 The hanging basket hook 28 adopts a cylindrical hook head.

[0070] The working principle of this embodiment is as follows:

[0071] When it is necessary to hook the wire mesh basket, move this device horizontally forward from one side of the basket, so that the connecting rod 29 is located on both sides of the basket and lower than the top ring rib of the basket. As the connecting rod moves forward, the hook can contact the ring rib on the side of the basket multiple times and swing backward to avoid it. As the connecting rod continues to move forward, the hook can pass over multiple ring ribs. As the connecting rod continues to move forward, the hook can move to the middle position of the basket. At this time, the hook is unfolded and in the middle position, and the hook is located below the ring rib of the basket. At this time, lift the device, and the two hooks hook onto the ring rib of the basket respectively. The basket can also rest against the mounting frame 1. At this time, the entire basket can be lifted by the mounting frame.

[0072] When it is necessary to remove the net basket, first move the device down so that the hanging hook is disengaged from the ribs of the net basket. Then move the entire device horizontally backward away from the net basket. During the backward movement, the hanging hook will repeatedly contact the ribs on the side of the net basket and swing forward to avoid them. As the connecting rod continues to move backward, the hanging hook can pass over multiple ribs and completely separate from the net basket.

[0073] Example 6:

[0074] See Figure 14 and Figure 15The fruit basket hook includes a crossbeam 23, with fixed base plates 24 mounted at both ends of the crossbeam 23. Horizontal L-shaped brackets 25 are rotatably mounted on each of the two fixed base plates 24, and the two L-shaped brackets 25 are symmetrically arranged. Each L-shaped bracket 25 includes a touch-sensitive horizontal arm 25a located in front of the fixed base plate 24 and a hanging basket side arm 25b vertically located at the outer end of the touch-sensitive horizontal arm 25a. The connection between the touch-sensitive horizontal arm 25a and the hanging basket side arm 25b is rotatably connected to the fixed base plate 24 via a pivot 26. The L-shaped bracket 25 can swing outwards to open or inwards to close around the pivot 26. The fixed base plate 24 is also provided with a driving component that drives the L-shaped bracket 25 to swing outwards and a stop component 27 that limits the outward opening stroke of the L-shaped bracket 25. Hanging basket hooks 28 are respectively provided on the inner sides of the two hanging basket side arms 25b. (See also...) Figure 14 The fruit basket handle 22 is a U-shaped handle, see [link / reference]. Figure 15 The handle 22 for the fruit basket is an arc-shaped handle.

[0075] The fixed base plate 24 is also equipped with a driving component that drives the L-shaped bracket 25 to swing outward. The driving component ensures that the L-shaped bracket 25 always has a tendency to swing outward. The driving component is a tension spring that pulls the L-shaped bracket 25 to swing outward. One end of the tension spring is connected to the hanging basket side arm 25b, and the other end of the tension spring is connected to the fixed base plate 24. The tension spring pulls the hanging basket side arm 25b to swing outward, thereby causing the entire L-shaped bracket 25 to swing outward.

[0076] The fixed base plate 24 is also provided with a stop 27 to limit the outward opening stroke of the L-shaped bracket 25. The stop 27 prevents the L-shaped bracket 25 from opening too far outward. The stop 27 is a pin or block located on the outside of the hanging basket side arm 25b. The stop 27 is connected to the support plate and cooperates with the outside of the hanging basket side arm 25b to limit the opening angle of the hanging basket side arm 25b and prevent the opening angle from being too large.

[0077] The working principle of this embodiment is as follows:

[0078] When it is necessary to hook the wire mesh basket, move this device from one side of the basket closer to it, so that the two hanging side arms 25b are located on both sides of the basket and the height of the two hanging hooks 28 is lower than the top ring rib of the basket. As the device moves closer, the contact horizontal arm 25a contacts the surface of the basket and rotates towards the side of the fixed base plate 24, causing the hanging side arms 25b to swing inward, so that the hanging hooks 28 move towards the side of the basket. When the hanging side arms 25b are horizontally against the fixed base plate 24, the hanging side arms 25b are vertical. At this time, the two hanging hooks 28 are inserted into the basket and located below the ring rib of the basket. Then, lift the device, and the two hanging hooks 28 hook onto the ring rib of the basket. After the basket is lifted, one side of the basket is always pressed against the contact horizontal arm 25a to ensure that the hanging hooks 28 never come off. At this time, the basket can be transported.

[0079] When it is necessary to remove the wire mesh basket, first move the device down so that the basket hook 28 is below the wire mesh basket's ribs. Then move the entire device away from the wire mesh basket. During the backward movement, since the wire mesh basket no longer presses against the contact arm 25a, the L-shaped bracket 25 swings outward and opens under the action of the driving component. At this time, the basket hook 28 also moves outward and away from the wire mesh basket. As the L-shaped bracket 25 continues to move backward, the basket hook 28 is completely separated from below the wire mesh basket's ribs, and the basket hanging side arm 25b stops under the action of the stop 27.

[0080] Example 7:

[0081] This embodiment has a basically the same structure as Embodiment 1, the main difference being the different structure of the vehicle body.

[0082] See Figure 16 The vehicle body includes a frame 8 and a fixed column. The lifting and sliding frame 3 slides vertically along the fixed column. A guide wheel is installed at the top of the fixed column. An electric winch 93 is installed on the vehicle body. The free end of the rope of the electric winch 93 passes around the guide wheel and is connected to the lifting and sliding frame 3.

[0083] In this application, the lifting and lowering of the lifting and sliding frame is achieved by a winch, rope, and guide wheel. However, it is not limited to this rope method; other methods such as motors, lead screws, and slide rails can also be used.
