Description

Technical Field

[0001] This application relates to the technical field of jackfruit planting and harvesting equipment, and more specifically, to a receiving device for jackfruit. Background Technology

[0002] Jackfruit, a large tropical fruit, is enormous, often weighing over 20 kilograms, and typically grows in the canopy of tall trees. Traditional harvesting methods rely mainly on manual climbing or simple tools (such as long-handled hooks). However, the jackfruit stalk is thick and tough, and the sticky latex secreted from the peel makes manual cutting inefficient and damaging, thus affecting fruit quality and shelf life. Harvesting from heights makes it difficult to precisely control the fruit's trajectory as it falls, easily damaging branches and nearby fruit, or endangering people on the ground, leading to economic losses and safety hazards. Currently, the market lacks jackfruit harvesting devices with effective support and protection. Utility Model Content

[0003] This application provides a receiving device for jackfruit, including a support base, a cushioning cloth, a retractable structure, a support rod, and an air cushion. Two support bases are arranged parallel and spaced apart. Each support base includes a support and a support rod. The two ends of the support rod are mounted to the two ends of the support via fixed seats. One support rod is rotatable, and the other is fixed. The two ends of the cushioning cloth are respectively fixed to the two support rods. Two retractable structures connect the upper and lower ends of the two support bases respectively. Each retractable structure includes two hinged connecting rods. The free ends of the two connecting rods are respectively fixed to the side walls of the support bases and are rotatable, allowing the support bases to fold and unfold. One end of the support rod is hinged to the support base, forming a triangular support structure with the support when unfolded. The air cushion is detachably connected to the support base. The side wall of the air cushion has a protrusion with a through hole for rope fixation. The air cushion is not fully inflated to utilize an air cushion layer to absorb impact force.

[0004] In some embodiments, the cushioning fabric is made of polypropylene woven fabric, Oxford cloth, or polyester canvas.

[0005] In some embodiments, the shrinking structure further includes a connecting piece and a sleeve. One end of the connecting rod has symmetrical notches on opposite sides, and the outer surface of the notches forms a cylindrical protrusion. The connecting piece engages with the protrusion through a through hole, allowing the connecting rod to rotate relative to the connecting piece. The sleeve is fitted onto the connecting rod.

[0006] In some embodiments, the sleeve is 0.5 to 0.9 times the length of the connecting rod, and when deployed, the sleeve slides to the hinge point of the two connecting rods to lock the structure.

[0007] In some embodiments, the connecting pieces of the retractable structure are symmetrically arranged on both sides of the connecting rod, and the sleeve restricts the relative rotation of the connecting rod to achieve unfolding and locking.

[0008] In some embodiments, the cushioning principle of the air cushion is the same as that of a fire-fighting air cushion, which disperses the impact force of the falling fruit through the compression-rebound process of the unfilled gas.

[0009] In some embodiments, the cushioning fabric retains excess fabric when unfolded to utilize the air layer formed by the fabric drooping to aid cushioning.

[0010] In some embodiments, the protruding through-hole of the air cushion is tied to the connecting rod of the bracket seat with a rope to ensure that the air cushion is fixed to the bottom of the bracket seat.

[0011] In some embodiments, the deflated air cushion can be used to wrap and store the entire support base.

[0012] In some embodiments, a control structure for controlling the rotation of the roller shaft is provided on the fixed base, including: a disk rotatably disposed on the fixed base, the outer surface of the disk having a plurality of first protrusions arranged in a circular array; a plurality of second protrusions arranged in a circular array at the upper end of the rotatable roller shaft, the first and second protrusions being perpendicular to each other and intersecting and extending into the interval to form a meshing structure; and an operating handle connected to the outside of the disk, by rotating the handle driving the disk to rotate, thereby controlling the rotation of the roller shaft through the meshing of the first and second protrusions.

[0013] The receiving device of this application adopts an innovative foldable structure and cushioning components, which effectively solves the problems of easy fruit damage and dangerous operation in traditional harvesting methods. Through the synergistic effect of the support base, cushioning cloth, shrink structure, support rod and air cushion, efficient and safe harvesting of jackfruit is achieved.

[0023] Please see Figure 1 and Figure 2This application provides a receiving device (100) for jackfruit, including a support (10), a cushioning cloth (20), a shrinking structure (30), a support rod (40), and an air cushion (50). Two supports (10) are arranged in parallel and spaced apart. Each support (10) includes a fixed rod (11) and a roller (12). The two ends of the roller (12) are installed on the two ends of the fixed rod (11) through a fixed seat (13). One roller (12) is rotatable, and the other roller (12) is fixed. The two ends of the cushioning cloth (20) are respectively fixed on the two rollers (12). Two shrinking structures (30) are respectively connected to the upper and lower ends of the two supports (10). The shrinking structure (30) includes two hinged connecting rods (31). The free ends of the two connecting rods (31) are respectively fixed on the side wall of the support (10) and can rotate to realize the folding and unfolding of the support (10). One end of the support rod (40) is hinged to the support (10), and when unfolded, it forms a triangular support structure with the fixed rod (11). The air cushion (50) is detachably connected to the support (10). The side wall of the air cushion (50) is provided with a boss (51) with a through hole for rope fixation. The air cushion (50) is not fully inflated to absorb the impact force using an air buffer layer.

[0024] The receiving device (100) of this application adopts an innovative foldable structure and buffer components, which effectively solves the problems of easy damage to fruit and dangerous operation in traditional picking methods. Through the synergistic effect of the support (10), buffer cloth (20), shrink structure (30), support rod (40) and air cushion (50), efficient and safe picking of jackfruit is achieved.

[0025] Two supports (10) are arranged in parallel and spaced apart. Each support (10) includes a fixed rod (11) and a roller (12). The two ends of the roller (12) are mounted on the two ends of the fixed rod (11) through fixed seats (13). The difference between the two rollers (12) is that one roller (12) is rotatable, while the other roller (12) is not rotatable. The two ends of the cushioning cloth (20) are fixed on the two rollers (12) respectively. In use, it can be unfolded by the rotatable roller (12), and in folding, it can be wound around the cushioning cloth (20) by the rotatable roller (12).

[0026] Please see Figure 1 The cushioning fabric (20) can be made of polypropylene woven fabric, Oxford cloth, or polyester canvas. The back of the cushioning fabric (20) can be provided with "well"-shaped reinforcing ribs (not shown) to enhance its strength. Furthermore, the cushioning fabric (20) can be made into a folded shape similar to a curtain to further absorb impact. The length of the cushioning fabric (20) is greater than the unfolded width of the two supports (10) to allow for slack, allowing it to be concave and drooping.

[0027] Furthermore, the fixed base (13) is provided with a control structure for controlling the rotation of the roller shaft (12). Specifically, the fixed base (13) is provided with a rotatable disc (141), and the outer surface of the disc (141) is provided with a plurality of first protrusions (142) arranged in a circular array. The upper end of the roller shaft (12) protrudes along the periphery to form a circular array of second protrusions (121) that match the first protrusions (142). The first protrusions (142) and the second protrusions (121) are perpendicular to the first protrusions (142) and intersect each other into the interval. An operating handle (143) is connected to the outside of the disc (141). By rotating the handle (143), the disc (141) is driven to rotate, and the rotation of the roller shaft (12) is controlled by the meshing of the first protrusions (142) and the second protrusions (121).

[0028] Please see Figure 1 and Figure 2 The two supports (10) are connected by a retractable structure (30) to achieve folding and unfolding functions. Specifically, the upper and lower ends of the two supports (10) are connected by a retractable structure (30), which is composed of two connecting rods (31) hinged at one end. The free ends of the two connecting rods (31) are rotatably mounted on the side wall of the support (10) through connecting seats. Furthermore, the retractable structure (30) also includes a connecting piece (32) and a sleeve (33).

[0029] A portion of material is symmetrically cut off from both sides of one end of the connecting rod (31) to form a notch (311) for accommodating the connecting pieces (32). The two connecting pieces (32) are symmetrically arranged relative to the center face of the connecting rod (31). The outer surface of the cut portion forms an outwardly extending cylindrical protrusion (312), the height of which is lower than the side surface of the connecting rod (31). The two ends of the connecting pieces (32) are provided with through holes (321) that match the protrusions (312). The protrusions (312) are embedded in the through holes (321), allowing the connecting rod (31) to rotate relative to the connecting pieces (32). The two connecting pieces (32) are respectively arranged on opposite sides of the connecting rod (31). A sleeve (33) is fitted onto the outside of the connecting rod (31), and its length is approximately 0.5 to 0.9 times the length of the connecting rod (31). After the two supports (10) are fully extended by the retraction mechanism, the two connecting rods (31) are on the same straight line and perpendicular to the side of the support (10). At this time, the sleeve (33) is moved axially to the middle position so that the midpoint of its axis basically coincides with the hinge point of the two connecting rods (31). When folding the support (10), the sleeve (33) is moved toward one of the connecting rods (31) to fold it.

[0030] One end of the support (10) is hinged to one end of the support rod (40) via a hinge seat 41, forming a stable triangular structure when unfolded. Specifically, one end of each fixed rod (11) is hinged to one end of the support rod (40) via a hinge seat 41, and the free ends of both can move closer or further apart to complete folding or unfolding. When unfolded, the free ends of the fixed rod (11) and the support rod (40) are placed on the ground, thus forming a stable triangular structure. Furthermore, it can be understood that the height of the support can be adjusted according to actual needs.

[0031] Please combine Figure 1 and Figure 3 The air cushion (50) and the support (10) are detachably connected. The side wall of the air cushion (50) is provided with multiple protrusions (51), and the protrusions (51) are provided with through holes that penetrate the upper and lower surfaces. In use, the air cushion (50) is placed on a flat surface, and the side wall with the protrusions (51) is placed against the bottom end of the support (10). The air cushion (50) and the support (10) are tied together with a rope (not shown). One end of the rope is tied to the protrusion (51) through the through hole, and the other end is tied to the unfolded connecting rod (31).

[0032] The air cushion (50) is not fully inflated, and its principle is similar to that of the fire-fighting air cushion (50)—dispersing the impact force through the reserved air buffer space inside. When the jackfruit falls, the elastic deformation of the air cushion (50) can absorb kinetic energy, reducing the risk of the fruit bouncing or breaking; at the same time, the unfilled gas further reduces the impact through the compression-rebound process, just as the fire-fighting air cushion (50) uses an air layer to achieve a soft landing when protecting falling personnel. The principle of the cushioning cloth (20) is basically the same, which also utilizes the margin and air to buffer the impact force.

[0033] The receiving device (100) of this application is used as follows:

[0034] First, fully extend the two supports (10) through the shrink structure (30), straighten the connecting rods (31) at both ends of the fixed rod (11) to be on the same straight line, and move the center of the sleeve (33) to the hinge point of the two connecting rods (31).

[0035] Next, adjust the height of the support rod (40) so that it contacts the ground and forms a stable triangular support structure, thereby enhancing the overall stability of the device.

[0036] Subsequently, the rotatable roller (12) is unfolded and the cushioning cloth (20) is unfolded to keep it with extra space so as to effectively receive the jackfruit during the harvesting process and to use the extra space to cushion the impact of the falling fruit and prevent it from popping out.

[0037] After the device is deployed, place the air cushion (50) at the bottom of the support (10) and secure it firmly with ropes through the through holes on the boss (51). The air cushion (50) is not fully inflated to prevent the jackfruit from popping out. The air cushion (50) effectively reduces the impact force on the device when the fruit falls during harvesting, while also preventing the fruit from being damaged by collision. After completing the above steps, the operator can begin the harvesting operation.

[0038] After harvesting, the device can be folded and stored. First, loosen the connection between the air cushion (50) and the support (10), remove the air cushion (50) and deflate it. Then, fold the support rod (40) towards the support (10), release the locking state of the shrink structure (30), and bring the two supports (10) closer together. Next, roll up the rotatable roller (12) to fold the cushioning cloth (20), and finally use the air cushion (50) to roll up the entire support (10) and tie it tightly with rope. The entire device is compact after folding, making it easy to transport and store, and significantly improving the convenience of use.

[0039] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application, the scope of which is defined by the claims and their equivalents.
