Description

Technical Field

[0001] This utility model relates to the field of orchard basket handling technology, and in particular to a touch-type opening and closing basket lifting device and a transport vehicle including such a basket lifting device. Background Technology

[0002] During the fruit harvest season, fruit picking is still mostly done manually. After picking the fruit from the tree, farmers place it in wire mesh baskets. Once the baskets are full, they carry them a short distance to the transport vehicle. Commonly used metal wire mesh baskets by farmers include rectangular and round baskets. See [link to relevant documentation]. Figure 21 See the top view of the square basket. Figure 22 This is a top view of a rectangular basket. Square and rectangular baskets can be collectively referred to as rectangular baskets. See also... Figure 23 See the top view of the round basket. Figure 24 These are front views of rectangular and round baskets. These metal mesh baskets are strong, durable, and have a long service life, making them a popular choice for fruit farmers. When filled with fruit, a basket can weigh over 30 kilograms, making it inconvenient for farmers to carry it around in the fields. A fall could result in fruit loss and injury, and the baskets also need to be lifted and carried onto transport vehicles, further complicating the process. Therefore, existing technologies disclose various transport vehicles for facilitating the transport of wire mesh baskets. These vehicles have hooks at the front to attach the baskets to the reinforcing ribs, allowing them to be hooked before being moved to the transport vehicle. While these hooks facilitate basket transport, existing hooks suffer from several problems: 1. Generally, only one hook is used. Although this achieves the purpose of hooking the basket, the stability and safety of a single hook are poor, and the basket is easily deformed, especially softer baskets, which cannot be hooked at all. This not only causes goods to scatter but also easily deforms and damages the basket. 2. The shape of the basket can only be transported, as wire mesh baskets on the market vary greatly in size, especially rectangular baskets. 3. On rough and bumpy roads, the basket is prone to swaying, posing a risk of disengagement during transport. Therefore, there is an urgent need for a basket-lifting device that provides stable basket hanging, prevents basket deformation, facilitates basket hooking, and is suitable for most basket shapes on the market. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a touch-type opening and closing basket lifting device and a transport vehicle including such a basket lifting device.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a touch-type opening and closing basket lifting device, including a fixed base plate arranged opposite to each other on the left and right. Horizontal L-shaped brackets are rotatably installed on the two fixed base plates respectively. The two L-shaped brackets are arranged symmetrically on the left and right. Each L-shaped bracket includes a touch horizontal arm located in front of the fixed base plate and a basket hanging side arm vertically arranged at the outer end of the touch horizontal arm. The connection between the touch horizontal arm and the basket hanging side arm is rotatably connected to the fixed base plate through a rotating shaft. The L-shaped bracket can swing outward to open or swing inward to close around the rotating shaft. The fixed base plate is also provided with a driving member that drives the L-shaped bracket to swing outward and a stop member that limits the outward opening stroke of the L-shaped bracket. Basket hooks are respectively provided on the inner side of the two basket hanging side arms.

[0005] As a preferred technical solution, the driving component is a tension spring that pulls the L-shaped bracket to swing outward, with one end of the tension spring connected to the L-shaped bracket and the other end of the tension spring connected to the fixed base plate;

[0006] Alternatively, the driving component may be a torsion spring sleeved on the outside of the rotating shaft, with one end of the torsion spring connected to the L-shaped bracket and the other end of the torsion spring connected to the fixed base plate;

[0007] Alternatively, the driving component may be a compression spring that pushes the L-shaped bracket to swing outward, with one end of the compression spring connected to the L-shaped bracket and the other end connected to the fixed base plate or crossbeam.

[0008] As a preferred technical solution, the stop is a pin or block located on the outside of the side arm of the hanging basket.

[0009] As a preferred technical solution, the inner ends of the left and right touch arms are positioned close to the symmetrical surfaces of the left and right hanging basket side arms.

[0010] As a preferred technical solution, a baffle is provided between the inner ends of the left and right touch arms, and the baffle covers the front side of the inner ends of the left and right touch arms.

[0011] As a preferred technical solution, the baffle is fixed on one of the touch arms, and the other end of the baffle is a free end that blocks the front side of the inner end of the other touch arm.

[0012] Alternatively, the top of the baffle may be provided with a connecting plate, the connecting plate may be provided with a transverse slot, and the inner ends of the two contact cross arms may be provided with studs or pins that slide along the transverse slot.

[0013] Alternatively, the baffle may be a webbing, with both ends of the webbing connected to the two touch arms respectively.

[0014] As a preferred technical solution, a longitudinal adjustment structure and / or a lateral adjustment structure for adjusting the position of the hanging basket hook are provided between the hanging basket side arm and the hanging basket hook.

[0015] As a preferred technical solution, the basket hook includes a connecting part and an upwardly bent hook head located at the inner end of the connecting part.

[0016] Another technical solution is a transport vehicle, including a frame on which the aforementioned touch-type opening and closing lifting device is installed.

[0017] As a preferred technical solution, the frame is provided with a column, and a lifting frame is slidably installed in front of the column. The touch-type opening and closing basket lifting device is connected to the lifting frame, and the basket hanging side arm is set facing forward. A basket support frame is provided on the lifting frame below the touch-type opening and closing basket lifting device. A travel wheel is provided on each side of the touch-type opening and closing basket lifting device on the frame, and a handrail is provided on the rear side of the frame.

[0018] As a preferred technical solution, the front end of the vehicle frame is provided with a driving wheel, the touch-type opening and closing basket lifting device is located at the rear end of the vehicle frame and the basket hanging side arm is arranged facing backward, and the rear side of the vehicle frame is provided with a handrail.

[0019] Alternatively, the vehicle frame may have wheels on both sides and a handrail on the rear side. The touch-sensitive opening and closing basket lifting device may be located at the front end of the vehicle frame, with the basket hanging arm facing forward.

[0020] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] This device provides a rotatable and closable L-shaped bracket, which includes a contact horizontal arm and a basket-hanging side arm. The inner side of the basket-hanging side arm is equipped with a basket hook, and the basket-hanging side arm and the contact horizontal arm can be linked for opening and closing. When the basket-hanging side arm is not pressed, the left and right contact horizontal arms tilt outwards, presenting an open state. This allows the basket hook to avoid obstruction before the basket is hooked and facilitates the basket's easy detachment from the hook. When the contact horizontal arm is pressed, the left and right contact horizontal arms swing inwards in a linked manner, presenting a closed state. At this time, the left and right basket hooks engage and insert into the side wall of the basket, achieving basket hooking. The advantages of this device are as follows:

[0022] 1. This device is equipped with at least two hooks for hanging baskets, which can be hooked on the left and right sides of the basket. The left and right support points are symmetrical, which can ensure the balance of the basket as much as possible, and the stability and safety are good. When the basket is full of goods, it can be lifted from the left and right, achieving the effect of lifting by hand, which can reduce the possibility of the basket deforming forward, reduce the deformation and damage of the basket, prevent the goods from falling, protect the goods, and can also hook some baskets with softer materials.

[0023] 2. The hooks are inserted into the wire mesh basket from both sides for hooking, and the opening and closing are achieved by the linkage of the L-shaped bracket. This enables automatic hooking and unhooking of the wire mesh basket. The basket can be lifted by raising the handle, completely replacing manual lifting. It has the advantages of simple structure and convenient control.

[0024] Third, during the movement of the transport vehicle, after the net basket is lifted, the hook can be stably inserted into the net basket, ensuring good stability of the net basket during transportation. Even if the net basket shakes on rough and bumpy road conditions, the net basket will not fall off the hook, the hanging of the net basket is stable, and the safety is good.

[0025] IV. This device is suitable for most basket shapes on the market and has good practicality. Attached Figure Description

Detailed Implementation

[0052] 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.

[0053] like Figure 1 As shown, a touch-type opening and closing basket lifting device includes two fixed base plates 1 arranged opposite each other on the left and right. Horizontal L-shaped brackets 2 are rotatably installed on the two fixed base plates 1. The two L-shaped brackets 2 are arranged symmetrically on the left and right, and cooperate to form a U-shaped structure with the opening facing forward. The L-shaped bracket 2 includes a touch horizontal arm 21 located in front of the fixed base plate 1 and a basket hanging side arm 22 vertically arranged at the outer end of the touch horizontal arm 21. A basket hanging hook 3 is provided on the inner side of each of the two basket hanging side arms 22. The connection between the touch horizontal arm 21 and the basket hanging side arm 22 is rotatably connected to the fixed base plate 1 through a rotating shaft 4. The L-shaped bracket 2 can swing outward to open or swing inward to close around the rotating shaft 4.

[0054] See Figure 1 The fixed base plate 1 includes upper and lower supporting plates and a connecting plate that fixes the two supporting plates together. The corner of the L-shaped bracket 2 is located between the upper and lower supporting plates. The rotating shaft 4 is a pin or stud that passes through the two supporting plates. The corner of the L-shaped bracket 2 is rotatably connected to the rotating shaft 4. The connecting plate also serves as a limiting plate to prevent the L-shaped bracket 2 from swinging outward. When the touch cross arm 21 abuts against the connecting plate or against the cross frame 12, it will be unable to continue rotating.

[0055] See Figure 3 The fixed base plate 1 is also equipped with a driving component that drives the L-shaped bracket 2 to swing outward. The driving component ensures that the L-shaped bracket 2 always has a tendency to swing outward. The driving component is a tension spring 5 that pulls the L-shaped bracket 2 to swing outward. One end of the tension spring 5 is connected to the hanging basket side arm 22, and the other end of the tension spring 5 is connected to the fixed base plate 1. The tension spring 5 pulls the hanging basket side arm 22 to swing outward, thereby causing the entire L-shaped bracket 2 to swing outward.

[0056] See Figure 1 and Figure 2The fixed base plate 1 is also provided with a stop to limit the outward opening stroke of the L-shaped bracket 2. The stop prevents the L-shaped bracket 2 from opening too far outward. The stop is a pin 6 or a block located on the outside of the hanging basket side arm 22. The stop is connected to the support plate and cooperates with the outside of the hanging basket side arm 22 to limit the opening angle of the hanging basket side arm 22 and prevent the opening angle from being too large.

[0057] The inward closing limit position of the L-shaped bracket 2 is achieved by the fixed base plate 1. When the touch cross arm 21 swings backward and contacts the fixed base plate 1, it can no longer rotate.

[0058] The hanging basket side arm 22 and the hanging basket hook 3 can be equipped with both a longitudinal adjustment structure and a lateral adjustment structure for adjusting the position of the hanging basket hook 3, or only a longitudinal adjustment structure or only a lateral adjustment structure. In this embodiment, both the longitudinal and lateral adjustment structures are provided. The longitudinal adjustment structure includes a longitudinal slot 7 along the length of the hanging basket side arm 22. The hanging basket hook 3 is connected to the hanging basket side arm 22 by bolts passing through the longitudinal slot 7. The longitudinal slot 7 is used to adjust the longitudinal position of the hanging basket hook 3. The lateral adjustment structure includes a lateral slot 8 on the hanging basket hook 3 perpendicular to the hanging basket side arm 22. The hanging basket hook 3 is connected to the hanging basket side arm 22 by bolts passing through the lateral slot 8. The lateral slot 8 is used to adjust the lateral position of the hanging basket hook 3. The longitudinal strip hole 7 and the transverse strip hole 8 can be fixed together with a bolt. By adjusting the longitudinal and transverse positions, the position of the hanging hook 3 can be finely adjusted, which is suitable for wire baskets of different sizes.

[0059] The basket hook 3 includes a connecting part and an upwardly bent hook head located at the inner end of the connecting plate. The upward bending of the hook head ensures that it hooks onto the reinforcing ribs of the basket. In this embodiment, the connecting part is plate-shaped, and the hook head is also plate-shaped. Of course, the connecting part can also be cylindrical, in which case the hook head is also cylindrical.

[0060] During installation, this device can be directly fixed to the vehicle body via the fixing base plate 1.

[0061] The working principle of this embodiment is as follows:

[0062] See Figure 2 This diagram shows the state of the wire mesh basket before or after it is hooked up. In this state, the side arms 22 of the basket are tilted outwards, and the distance between the left and right side arms 22 is greater than the width of the basket, indicating an open state. (See also...) Figure 3This is a diagram showing the state after the wire basket is hooked up. At this time, the side arm 22 of the hanging basket is vertical, and the distance between the left and right side arms 22 of the hanging basket is just right to match the wire basket, presenting a closed state.

[0063] 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 22 are located on both sides of the basket and the height of the two hanging hooks 3 is lower than the top ring rib of the basket. As the device moves closer, the contact arm 21 contacts the surface of the basket and rotates towards one side of the fixed base plate 1, causing the hanging side arms 22 to swing inward, so that the hanging hooks 3 move towards one side of the basket. When the hanging side arms 22 are horizontally against the fixed base plate 1, the hanging side arms 22 are vertical. At this time, the two hanging hooks 3 are respectively inserted into the basket and located below the ring rib of the basket. See the state. Figure 3 At this time, the device is lifted, and the two hooks 3 hook onto the ribs of the net basket respectively. After the net basket is lifted, the hooks 3 ensure that the fruit basket will not come off the hook. At this time, the net basket can be transported.

[0064] When the wire mesh basket needs to be removed, first move the device downwards so that the basket hook 3 is below the ribs of the wire mesh basket. Then move the entire device away from the wire mesh basket. During the backward movement, since the wire mesh basket is no longer pressing against the contact arm 21, the L-shaped bracket 2 swings outwards and opens under the action of the driving component. At this time, the basket hook 3 also moves outwards and away from the wire mesh basket. As the L-shaped bracket 2 continues to move backwards, the basket hook 3 completely separates from below the ribs of the wire mesh basket, and the basket side arm 22 stops under the action of the stop component. See the fully opened state. Figure 2 .

[0065] Figure 2 and Figure 3 The basket shown is rectangular, and its entire surface can be pressed against the touch arm 21. This not only makes it easier to press against the touch arm 21 but also improves stability during handling. To make this device also suitable for round baskets, the inner ends of the left and right touch arms 21 are positioned close to the symmetrical planes of the left and right hanging arms 22. That is, when the left and right touch arms 21 are closed, the gap between them is small, which is beneficial for hooking round baskets. See [link to documentation]. Figure 5 At this time, the surface of the basket is more likely to press against the swing of the touch arm 21.

[0066] This device is suitable for various basket shapes, including square baskets, rectangular baskets, and round baskets.

[0067] Example 2:

[0068] This embodiment is basically the same in structure as Embodiment 1, the main difference being the structure of the driving component. In this embodiment, see... Figure 6 The driving component is a torsion spring 9 sleeved on the rotating shaft 4. One end of the torsion spring 9 is connected to the L-shaped bracket 2, and the other end of the torsion spring 9 is connected to the fixed base plate 1. There may be one or two torsion springs 9.

[0069] Of course, the driving component can also be a compression spring that pushes the L-shaped bracket 2 to swing outward. One end of the compression spring is connected to the hanging basket side arm 22, and the other end of the compression spring is connected to the fixed base plate 1. The tension spring 5 pulls the hanging basket side arm 22 to swing forward, thereby causing the entire L-shaped bracket 2 to swing outward. Of course, the other end of the compression spring can also be provided on the crossbeam 12.

[0070] Example 3:

[0071] This embodiment is a further improvement on the first embodiment. A baffle 10 is provided between the inner ends of the left and right touch arms 21, and the baffle 10 covers the front side of the inner ends of the left and right touch arms 21.

[0072] See Figure 7 The baffle 10 is fixed to one of the touch arms 21, and the other end of the baffle 10 is a free end that covers the front side of the inner end of the other touch arm 21. The baffle 10 can cover the gap between the two touch arms 21, preventing the touch arm 21 from being accidentally inserted into the basket and damaging the basket and the fruit inside. The baffle 10 can be a thin metal plate, or it can be a soft plate, such as a rubber plate.

[0073] Of course, the baffle can also be a webbing, with both ends of the webbing fixed to the two touch arms respectively. When the two touch arms 21 swing forward before lifting the basket, the webbing is stretched to cover the gap between the two touch arms 21; when the two touch arms 21 swing backward to lift the basket, the webbing is relaxed.

[0074] Example 4:

[0075] This embodiment is a further improvement on the first embodiment. A baffle 10 is provided between the inner ends of the left and right touch arms 21, and the baffle 10 covers the front side of the inner ends of the left and right touch arms 21.

[0076] See Figure 8 and Figure 9 The top of the baffle 10 is provided with a connecting plate 11, which has transverse slots. Studs that slide along the transverse slots are installed on the inner ends of the two contact arms 21. (See also...) Figure 8This is a diagram showing the state of the touch arm 21 in its natural state. When the wire mesh basket is hooked, the basket will first press against the baffle 10, which will then cause the touch arm 21 to swing backward. The stud will slide along the transverse slot. See the final state diagram. Figure 9 .

[0077] Example 5:

[0078] This embodiment is basically the same in structure as Embodiment 1, the main difference being the number of basket hooks 3. In Embodiment 1, only one basket hook 3 is provided on each side arm 22, while in this embodiment, two basket hooks 3 are provided on each side arm. See [link to previous embodiment]. Figure 10 and Figure 11 Two hooks are provided on one side of the wire mesh basket, which makes it easier to hang rectangular baskets and ensures the stability of the baskets.

[0079] Example 6:

[0080] The structure of this embodiment is basically the same as that of Embodiment 1, the main difference being the different structure of the hanging basket hook 3 and the different installation method.

[0081] In this embodiment, see Figure 12 The hanging basket hook 3 includes a connecting part and an outwardly bent hook head located inside the connecting part. The connecting part is a screw. The longitudinal adjustment structure includes a longitudinal strip hole 7 located on the side of the hanging basket side arm. The screw passes horizontally through the longitudinal strip hole 7 and is fixed to the hanging basket side arm 22 by bolts. The screw can be adjusted in the longitudinal position through the longitudinal strip hole 7, and the screw can also be adjusted in the lateral position by bolts, serving as a lateral adjustment structure.

[0082] Example 7:

[0083] In Embodiment 1, the fixed base plate 1 can be directly fixed and installed to achieve the fixation of the basket lifting device. In this embodiment, a crossbeam 12 can be connected between the two fixed base plates 1, which facilitates the installation of this device. The fixed base plate 1 can be welded and fixed to the crossbeam 12, or the crossbeam 12 can be provided with transverse slots through which the fixed base plate 1 is fixed to the crossbeam 12. See [reference needed]. Figure 13 On the other hand, the touch arm 21 can be limited to abut against the touch arm 21.

[0084] This device is also applicable to a variety of transport vehicles. The following are some examples, but it is not limited to these types of transport vehicles.

[0085] Example 8:

[0086] This embodiment is a further improvement on the first embodiment, applying the first embodiment to a lifting and transporting vehicle.

[0087] See Figures 14 to 16 A transport vehicle includes a frame on which a touch-sensitive opening and closing basket lifting device is mounted. The frame has a column 13, and a lifting frame 14 is slidably mounted in front of the column 13. The touch-sensitive opening and closing basket lifting device is connected to the lifting frame 14, with the basket hanging arm 22 facing forward. A wheel 16 is located on each side of the touch-sensitive opening and closing basket lifting device on the frame, and a handrail 17 is located at the rear of the frame. To ensure better handling, a basket support frame 15 is provided on the lifting frame, located below the touch-sensitive opening and closing basket lifting device, for supporting the basket. The basket support frame 15 includes a U-shaped basket support frame or an arc-shaped basket support frame; see [link to U-shaped basket support frame description]. Figure 14 See the curved support frame. Figure 15 .

[0088] In this embodiment, the column 13 can be a single-layer column 13 or a double-layer telescopic column 13, and the lifting frame 14 can be raised and lowered by a winch and rope. Of course, the lifting frame 14 can also be raised and lowered by other means such as lead screws and guide rails.

[0089] The working principle of this embodiment is as follows:

[0090] Before transport, the net basket filled with fruit is placed on the ground. The user stands at the back of the vehicle and pushes the transport vehicle forward so that the hanging arm 22 is aligned with the net basket and the hanging hook 3 is located below the top rib ring of the net basket. Then, as the vehicle gradually approaches the net basket, the net basket presses against the horizontal arm 21 and swings backward, causing the left and right hanging arms 22 to swing inward, which drives the hanging hook 3 to insert below the rib ring of the net basket. Then, the lifting frame 14 drives the device upward to lift the net basket. After the net basket is lifted, the handrail 17 controls the vehicle to tilt backward. At this time, the net basket is transported by the transport vehicle. During the transport process, under the action of the weight of the fruit basket, the hanging hook 3 ensures that the fruit basket will never fall off the hook, ensuring the safety of the transport.

[0091] After the wire mesh basket is transported to the designated position, the lifting frame 14 drives the basket to continue to rise to a certain height, completing the lifting of the basket. When the lifting height of the basket exceeds the height of the carriage, the carriage is moved closer to the carriage so that the basket is directly above the carriage. At this time, the lifting frame 14 is lowered so that the basket can be placed directly on the carriage, and the basket hook 3 is lower than the height of the basket rib ring. Then the carriage is pulled outward away from the basket. At this time, the basket hanging arm 22 swings outward, and the basket hook 3 is successfully unhooked, completing the automatic unloading of the basket.

[0092] Example 9:

[0093] This embodiment is a further improvement on the first embodiment, applying the first embodiment to a wheelbarrow transport vehicle.

[0094] See Figure 17 and Figure 18 A transport vehicle includes a frame on which a touch-sensitive opening and closing basket lifting device is mounted. The front end of the frame has a wheel 16. The touch-sensitive opening and closing basket lifting device is located at the rear end of the frame, with the basket hanging arm 22 facing rearward. A handrail 17 is located on the rear side of the frame. The touch-sensitive opening and closing basket lifting device can be located above or below the handrail 6.

[0095] The working principle of this embodiment is as follows:

[0096] Before handling, the fruit baskets filled with fruit are placed on the ground. The operator moves the transport cart to the front of the fruit baskets, with the user standing behind the cart. The rear of the cart is positioned directly opposite the fruit baskets, and the hook 3 is positioned below the top rib ring of the basket. The cart is then pulled backward. As the cross arm 21 is pressed against the basket, it causes the hook 3 to swing inward and insert below the rib ring of the basket. The state before the fruit baskets are lifted off the ground is described in [reference needed]. Figure 17 ;

[0097] When the operator holds the handle 17 and lifts it upwards, the left and right ends of the fruit basket are hooked by the basket hooks 3, and the fruit basket is lifted off the ground. After the fruit basket is lifted, the basket hooks 3 ensure that the fruit basket will not fall off under the weight of the fruit basket, ensuring the safety of transportation. At this time, the transport vehicle is similar to a traditional single-wheeled cart. The use of a single wheel is well-suited for walking in narrow spaces and rugged areas. The balance of the vehicle can be maintained by controlling the left and right handles 17. When the fruit basket is transported to the designated position, the handles 17 are pressed down to put the fruit basket on the ground, and then the transport vehicle is pushed forward to completely separate it from the net basket.

[0098] Example 10:

[0099] This embodiment is a further improvement on Embodiment 1, applying Embodiment 1 to a transport vehicle.
