Description

Technical Field

[0001] This invention relates to the technical field of fruit picking in wetland conservation, and in particular to a multifunctional fruit picking device for planting crops in wetland conservation areas. Background Technology

[0002] Currently, the construction of wetlands around cities has become one of the important projects for people's livelihood and environmental protection. Since wetland construction needs to be based on lakes or rivers, supplemented by vegetation planting to improve wetland soil and thus improve the surrounding environment, some greenways or pedestrian walkways need to be interspersed in wetlands. In order to improve environmental quality, some fruit trees are usually planted. During the fruiting season, the fruit falls into the wetland and is not easy to pick up, which can easily cause the fruit to rot and produce odors, thus affecting the wetland environment.

[0003] Chinese patent CN110249795B discloses a multifunctional fruit picker for wetland protection crop cultivation. Addressing the problems of low adaptability and low operating efficiency in existing models, the following solution is proposed: It includes a picking frame and a conical picking cage. Two parallel rotating seats are rotatably connected to the inner side of the picking frame. The conical picking cage is detachably connected to the inner side of the rotating seats. The conical picking cage includes a large shaping ring, a small shaping ring, and several steel ropes. The conical picking cage is designed as a conical cylinder, providing a larger contact area with the ground. This allows for the picking of fruits over a wider area of ​​the ground, increasing picking speed and efficiency, and significantly enhancing adaptability to picking different types of fruits.

[0004] The aforementioned technologies have the following drawbacks: In existing technologies, fruits are picked up from the ground using a cylindrical structure formed by multiple soft strips. However, during the picking process, once the fruit enters the cylindrical structure, it will be located at the bottom of the cylindrical structure, affecting the entry of subsequent fruits into the cylindrical structure. Furthermore, the fruits will gradually accumulate at the bottom of the cylindrical structure, hindering the entry of subsequent fruits into the device by squeezing the soft strips. It is necessary to empty the fruits every once in a while, resulting in poor picking efficiency. Therefore, a multifunctional fruit picking device for wetland protection crop cultivation is proposed. Summary of the Invention

[0005] To reduce the impact of picked fruits on subsequent fruit picking, this invention provides a multifunctional fruit picking device for wetland conservation crop cultivation.

The support cylinder is located on the lower side of the support platform. An end plate is installed at one end of the support cylinder. The upper end of the end plate is detachably installed on the bottom surface of the support platform. A grounding structure is provided on the other side of the support cylinder.

[0013] Optionally, the storage frame is located between two adjacent plate-shaped structures of the linkage ring frame, and the contact surface between the storage frame and the plate-shaped structure of the linkage ring frame is provided with a notch-shaped structure that matches the notch of the plate-shaped structure of the linkage ring frame.

[0014] The storage frame has multiple elastic stops fixed to its notch-shaped portion.

[0015] The elastic stop bar is designed to bend back and forth.

[0016] Optionally, the distance between the end of the storage frame near the end plate and the axis of the support cylinder is less than the distance between the other end of the storage frame and the axis of the support cylinder.

[0017] The opening range at the upper end of the end plate is larger than the opening range of the storage frame at the end closest to the end plate.

[0018] Optionally, the power feeding structure includes a power-rotatable conveyor belt and two side mounting plates. The side mounting plates are fixed to the support platform and the end plate. The conveyor belt is installed between the two side mounting plates. The portion of the conveyor belt located below the support platform is vertical, and the upper end of the conveyor belt is inclined and bent towards the support platform.

[0019] The outer ring surface of the conveyor belt is fixed with multiple evenly distributed fruit support plates.

[0020] Optionally, two limiting fruit-blocking plates are fixedly installed on the upper surface of the support platform, and the two limiting fruit-blocking plates are respectively set to correspond one-to-one with the two side mounting plates.

[0021] A fruit-sliding plate is fixed on the upper surface of the support platform. A fruit-collecting box is installed at the end of the support platform away from the conveyor belt, and the end of the fruit-sliding plate near the fruit-collecting box is located on the lower side of the other end.

[0022] Optionally, the portion of the support cylinder located between the two ring plates of the linkage ring frame is provided with an annular recess, and a variable diameter cylinder is fixedly sleeved on the annular recessed portion of the support cylinder.

[0023] The storage frame is fixed with a sliding rod at one end near the axis of the support cylinder, and the storage frame is elastically rotatably connected to the plate-shaped structure of the linkage ring frame at the other end near the end plate.

[0024] Optionally, the outer ring surface of the variable diameter cylinder is provided with a structure that protrudes towards the end away from the support cylinder, and the remaining part of the support cylinder is a cylindrical structure coaxial with the support cylinder, and the connection between the protruding structure and the cylindrical structure of the variable diameter cylinder is arc-shaped.

[0025] The protruding structure of the variable diameter cylinder corresponds to the position of the opening on the end plate.

[0026] Optionally, the support platform is provided with two power-rotatable movable wheel sets on its lower side, and a power telescopic component for controlling the up-and-down movement of the movable wheel sets is installed on the bottom surface of the support platform.

[0027] In summary, the present invention has the following beneficial technical effects: 1. By setting up components such as a storage frame, elastic baffles, a grounding structure, and a linkage ring frame, the grounding structure moves in contact with the ground, causing the linkage ring frame to rotate. This causes different storage frames and elastic baffles to contact the ground. Fruits entering the storage frame follow the linkage ring frame to the opening position with the end plate. The fruit in the storage frame falls from the opening of the end plate into the power feeding structure. The power feeding structure delivers the fruit to the upper side of the support platform, so that when the storage frame rotates back to the ground position, the inside of the storage frame is empty, facilitating the entry of fruit into the storage frame. 2. The present invention, through the inclined end face of the storage frame, when the storage frame rotates to the part communicating with the opening of the end plate, because the distance between the end of the storage frame near the end plate and the axis of the support cylinder is smaller than the distance between the other end of the storage frame and the axis of the support cylinder, causes the fruit in the storage frame to tend to move towards the opening side of the end plate, assisting the fruit to be discharged outward from the opening of the end plate. 3. This invention, by setting up components such as a sliding rod and a variable-diameter cylinder, allows the storage frame to be parallel to the axis of the support cylinder when the sliding rod is located in the cylindrical part of the variable-diameter cylinder, under the action of elastic connection with the linkage ring frame. When the storage frame rotates to the lower side, it can pick up the fruit. When the storage frame rotates into the opening range of the end plate, the sliding rod moves to the protruding position of the variable-diameter cylinder. The protrusion of the variable-diameter cylinder pushes the sliding rod, causing the storage frame to rotate from the end away from the end plate to the end away from the support cylinder, assisting the fruit in the storage frame to be discharged from the opening of the end plate. 4. This invention, by setting up components such as a conveyor belt, fruit support plate, limiting fruit stop plate, and sliding fruit plate, allows the fruit falling from the opening of the end plate to fall onto the adjacent fruit support plate on the lower side. Then, as the conveyor belt rotates, it drives the fruit support plate upward, carrying the fruit to the upper side of the support platform. After the fruit support plate moves to the inclined part of the conveyor belt, the fruit on the upper side of the fruit support plate falls onto the inclined sliding fruit plate on the upper side of the support platform, and the fruit rolls off the sliding fruit plate into the fruit collection box.

[0038] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0039] This invention discloses a multifunctional fruit-picking tool for planting crops in wetlands. For example... Figures 1-9 As shown, it includes a support platform 1 and a support cylinder 2. The support cylinder 2 is located under the support platform 1. An end plate 3 is installed at one end of the support cylinder 2. The upper end of the end plate 3 is detachably installed on the bottom surface of the support platform 1. A grounding structure 5 is provided on the other side of the support cylinder 2. The grounding structure 5 is rotatably connected to the support cylinder 2.

[0040] The grounding structure 5 includes a grounding plate 51 and an inner cylinder 52. The inner cylinder 52 is rotatably inserted into the support cylinder 2. The inner cylinder 52 is coaxially fixed with the grounding plate 51. The linkage ring frame 4 is coaxially fixed with the grounding plate 51. A bearing is installed at the connection between the inner cylinder 52 and the support cylinder 2 to improve the smoothness of rotation between the support cylinder 2 and the inner cylinder 52.

[0041] Multiple elastically extendable grounding rods 53 are installed on the circumferential side of the grounding plate 51. The extension line of the grounding rod 53 intersects the axis of the grounding plate 51 perpendicularly. The end of the grounding rod 53 away from the grounding plate 51 is round. The round shape of the grounding rod 53 facilitates the contact between the grounding rod 53 and the ground to bear force. When the support platform 1 moves, the grounding plate 51 contacts the ground through the grounding rod 53 and the grounding plate 51 rotates relative to the support cylinder 2.

[0042] Two power-rotatable movable wheel sets 9 are provided on the lower side of the support platform 1. The movable wheel sets 9 support the support platform 1 by contacting the ground. The movable wheel sets 9 consist of a first motor, wheels and axles. The wheels and axles are installed coaxially. The first motor is connected to the axle through a coupling. When the wheels are in contact with the ground, the first motor drives the wheels to rotate through the axle, controlling the movement of the support platform 1. A power telescopic component 10 is installed on the bottom surface of the support platform 1 to control the up and down movement of the movable wheel sets 9. The power telescopic component 10 can be an electric telescopic rod or a hydraulic cylinder or other power telescopic structure to control the height of the support platform 1 from the ground, thereby controlling whether the grounding plate 51 is in contact with the ground. When not in use, the grounding plate 51 is controlled to detach from the ground, facilitating the overall movement of the device.

[0043] A rotatable linkage ring frame 4 is sleeved on the outer surface of the support cylinder 2, and the linkage ring frame 4 is coaxially connected to the grounding structure 5.

[0044] Multiple circumferentially distributed storage frames 6 are installed on the outer ring surface of the linkage ring frame 4. The linkage ring frame 4 is composed of two ring plates and multiple straight plate-shaped structures. The ring plate-shaped structures of the linkage ring frame 4 are sleeved on the outer surface of the support cylinder 2. The ring plate-shaped structures of the linkage ring frame 4 and the support cylinder 2 are connected by bearings to improve the smoothness of the rotation of the linkage ring frame 4. The two ends of the plate-shaped structures of the linkage ring frame 4 are respectively connected to the two ring plate-shaped structures of the linkage ring frame 4.

[0045] The storage frame 6 is open at the end away from the axis of the linkage ring frame 4. Multiple horizontally distributed elastic baffles 7 are installed at the open end of the storage frame 6 away from the linkage ring frame 4. When the elastic baffles 7 near the ground come into contact with the fruit, the elastic baffles 7 are opened by the pressure of the fruit, so that the fruit can enter the storage frame 6 between the adjacent elastic baffles 7. The storage frame 6 is open at the end near the end plate 3. Before the grounding rod 53 is at its maximum compression, the storage frame 6 is in contact with the ground.

[0046] The plate-shaped structure of the linkage ring frame 4 has a notch at the end away from the support cylinder 2, and the plate-shaped structure of the linkage ring frame 4 is parallel to the axis of the support cylinder 2.

[0047] The storage frame 6 is located between two adjacent plate-shaped structures of the linkage ring frame 4. The contact surface between the storage frame 6 and the plate-shaped structure of the linkage ring frame 4 is provided with a notch-shaped structure that matches the notch of the plate-shaped structure of the linkage ring frame 4, so that the notch of the plate-shaped structure of the storage frame 6 and the linkage ring frame 4 will not crush the fruit when it is close to the ground.

[0048] Multiple elastic baffles 61 are fixed to the notch-shaped portion of the storage frame 6. The elastic baffles 61 ensure that the fruit entering the storage frame 6 will not roll from the notch of the plate structure of the storage frame 6 and the linkage ring frame 4 into the interior of the adjacent storage frame 6.

[0049] The elastic barrier 61 is designed to bend back and forth. When the elastic barrier 61 comes into contact with the fruit on the ground, the elastic barrier 61 deforms along the bending part, so as not to crush the fruit.

[0050] The distance between the end of the storage frame 6 near the end plate 3 and the axis of the support cylinder 2 is less than the distance between the other end of the storage frame 6 and the axis of the support cylinder 2. When the storage frame 6 rotates to the position above the axis of the support cylinder 2, the fruit in the storage frame 6 has a tendency to roll toward the end plate 3. The opening range at the upper end of the end plate 3 is larger than the opening range at the end of the storage frame 6 near the end plate 3, so that the fruit in the storage frame 6 can move to the opening of the end plate 3 through one end opening.

[0051] The support cylinder 2 is located between the two ring plates of the linkage ring frame 4 and is set in an annular recess. The annular recess of the support cylinder 2 is fixedly sleeved with a variable diameter cylinder 62.

[0052] The storage frame 6 is fixed with a sliding rod 63 at one end near the axis of the support cylinder 2. The storage frame 6 is elastically rotatably connected to the plate structure of the linkage ring frame 4 at one end near the end plate 3. The elastic connection is made by elastic elements such as torsion springs. Under the elastic connection between the storage frame 6 and the linkage ring frame 4, the storage frame 6 tends to be parallel to the axis of the support cylinder 2.

[0053] The upper side of the end plate 3 is open, and the outer ring surface of the variable diameter cylinder 62 is provided with a structure that protrudes away from the end of the support cylinder 2. The rest of the support cylinder 2 is a cylindrical structure coaxial with the support cylinder 2. The connection between the protruding structure and the cylindrical structure of the variable diameter cylinder 62 is arc-shaped, so that the sliding rod 63 can move smoothly from the cylindrical position of the support cylinder 2 to the protruding part.

[0054] The protruding structure of the variable diameter cylinder 62 corresponds to the opening position of the end plate 3. When one end of the storage frame 6 is completely moved to the opening range of the end plate 3, the corresponding sliding rod 63 moves to the protruding part of the variable diameter cylinder 62, pushing the storage frame 6 away from the end plate 3 to rotate away from the support cylinder 2.

[0055] An upward feeding structure 8 is installed at the end of the end plate 3 away from the support cylinder 2, and the power feeding structure 8 is connected to the outside of the opening of the end plate 3.

[0056] The power feeding structure 8 includes a power-rotatable conveyor belt 81 and two side mounting plates 82. The side mounting plates 82 are fixed to the support platform 1 and the end plate 3. The conveyor belt 81 is installed between the two side mounting plates 82. A conveyor wheel is provided at both the inner and outer turning points of the conveyor belt 81. The conveyor wheel is rotatably connected to the side mounting plate 82. A second motor is mounted on one of the side mounting plates 82. The second motor is connected to one of the conveyor wheels via a coupling. When the second motor starts, it can drive the conveyor belt 81 to rotate. A fixed outer ring surface of the conveyor belt 81 is... Multiple evenly distributed fruit support plates 83 are provided. The conveyor belt 81 is located on the lower side of the support platform 1 and is vertical. The upper end of the conveyor belt 81 is inclined and bent towards the support platform 1. The fruit support plates 83 located between the end plate 3 and the conveyor belt 81 are in contact with the end plate 3. When the conveyor belt 81 rotates, the fruit support plates 83 located between the end plate 3 and the conveyor belt 81 tend to move upward. Fruits falling from the opening of the end plate 3 fall onto the upper side of the lower fruit support plate 83. Then, when the conveyor belt 81 rotates, the fruit support plates 83 lift the fruit upward and move it to the upper side of the support platform 1.

[0057] Two limiting fruit-stopping plates 84 are fixedly installed on the upper surface of the support platform 1, and the two limiting fruit-stopping plates 84 are respectively set to correspond one-to-one with the two side mounting plates 82.

[0058] A fruit sliding plate 85 is fixed on the upper surface of the support platform 1. Fruits falling from the fruit support plate 83 can fall onto the upper side of the fruit sliding plate 85. A fruit receiving box 86 is installed at the end of the support platform 1 away from the conveyor belt 81. The end of the fruit sliding plate 85 near the fruit receiving box 86 is located on the lower side of the other end. The limiting fruit blocking plates 84 on both sides limit the range of fruit rolling. Fruits falling onto the upper side of the fruit sliding plate 85 roll into the fruit receiving box 86 under gravity due to the tilt setting.

[0059] The working principle is as follows: the grounding structure 5 is brought into contact with the ground. When the equipment moves, the grounding structure 5 moves in contact with the ground, causing the linkage ring frame 4 to rotate. The linkage ring frame 4 causes different storage frames 6 and elastic baffles 7 to come into contact with the ground. The fruit on the ground is deformed by the elastic baffles 7 in contact with the ground, and the fruit enters the storage frame 6 between the two elastic baffles 7. The fruit in the storage frame 6 follows the linkage ring frame 4 to the opening position with the end plate 3. The fruit in the storage frame 6 falls into the power feeding structure 8 from the opening of the end plate 3. The power feeding structure 8 sends the fruit to the upper side of the support platform 1, so that when the storage frame 6 rotates back to the ground position, the inside of the storage frame 6 is empty, which facilitates the fruit to enter the storage frame 6.

[0060] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
