Description

Technical Field

[0001] The invention belongs to the technical field of lotus pod picking and relates to a lotus pod picking device. Background Art

[0002] Lotus seeds have the effects of cooling down and relieving summer heat, nourishing the heart and calming the mind. They are distributed in all parts of China and even Southeast Asia, especially in the south. Lotus seeds are more common. At present, lotus pods are usually picked by sickles or bamboo poles tied with steel rings and fishing nets. When using sickles, due to the limited length of sickles, pickers must take fishing boats and move continuously during use, which is not efficient. In the process of picking with bamboo poles tied with steel rings and fishing nets, pickers usually stand on the shore, drive the steel rings with bamboo poles to pull and cut off the rhizomes of lotus pods, and lotus pods fall into the fishing nets. Since the stems of lotus pods are long, part of the force is used to pull the stems and leaves during the picking process, so this method has high labor intensity. In addition, due to the wide area of ​​lotus ponds, bamboo poles cannot reach all places, and this method of picking lotus pods is easy to leave lotus pods behind. Summary of the invention

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] Reference Figures 1 to 3 , a lotus pod picking device, comprising:

[0027] Rack 1;

[0028] A joystick 2, wherein the joystick 2 is mounted on the frame 1 via a sliding mechanism, and a housing 3 is fixedly disposed on the front end of the joystick 2; a telescopic arm 4 is slidably disposed in the housing 3, and the telescopic arm 4 is connected to a telescopic member of a telescopic drive mechanism disposed in the housing 3; a retracting blade head 41 is fixedly disposed on the end of the telescopic arm 4, and a retracting blade groove 411 of a curved structure formed toward one side of the telescopic arm 4 is formed on the retracting blade head 41; a retracting blade 412 is disposed on the inner edge of the retracting blade groove 411; a fixed blade head 51 with a blade facing forward is disposed at the front end of the housing 3, and a shear cut is formed between the fixed blade head 51 and the retracting blade 412 of the retracting blade head 41;

[0029] The collecting frame 8 is fixed on the lower side of the housing 3 , and the collecting frame 8 is located below the fixed cutter head 51 .

[0030] The frame 1 can be fixed vertically on the fishing boat. When the device is used, the joystick 2 is operated to rotate on the frame 1 through the sliding mechanism, and the joystick 2 can also slide back and forth on the sliding mechanism, thereby increasing the range of motion of the telescopic arm 4. When the telescopic arm 4 moves below the lotus pod, the lotus pod stem enters the retracting knife groove 411. At this time, the telescopic drive mechanism is started, and the telescopic member drives the telescopic arm 4 to retract into the housing 3, and the retracting knife groove 411 drives the lotus pod stem to approach the fixed blade head 51, and the distance between the fixed blade head 51 and the lotus pod stem gradually decreases, and finally the shearing cut formed by the fixed blade head 51 and the retracting blade 412 cuts off the lotus pod stem, and the separated lotus pod falls into the collection frame 8 below under the action of gravity. Then, under the action of the telescopic drive mechanism, the telescopic arm 4 extends out of the housing 3, and the retracting blade 412 and the retracting knife groove 411 are away from the fixed blade head 51.

[0031] In the above process, the range of motion of the telescopic arm 4 is increased by operating the joystick 2, reducing the movement of the picker; the retracting knife groove 411 is used to retract and fix the lotus stem. After the lotus stem is located in the retracting knife groove 411, this structure helps to cut it off by the shearing cut formed by the fixed knife head 51 and the retracting knife head 41, thereby effectively improving the picking efficiency of the lotus and reducing the labor intensity. In addition, the device has a simple structure and low cost.

[0032] Reference Figure 3 Specifically, a fixed stopper 42 is provided on the outer edge of the retracting blade head 41, and an obtuse angle 421 is formed between the stopper 42 and the retracting blade head 41. Preferably, the angle 421 is 145 degrees.

[0033] When the telescopic arm 4 is located below the lotus head, the telescopic drive mechanism is activated. The telescopic member drives the telescopic arm 4 to retract into the housing 3. The telescopic arm 4 drives the blocking rod 42 to make the blocking rod 42 contact with the lotus stem. As the distance between the telescopic arm 4 and the housing 3 gradually decreases, the lotus stem enters the retracting knife groove 411 along the length direction of the blocking rod 42.

[0034] This structure plays a guiding role, helping the lotus stem to enter the retracting knife groove 411. At the same time, the blocking rod 42 effectively expands the range of the retracting knife groove 411 for retracting and fixing the lotus stem, thereby reducing the difficulty of the picker to operate the operating lever 2.

[0035] Reference Figure 2 and Figure 3 Specifically, a stopper 43 is fixedly provided on the end of the telescopic arm 4 , and the stopper 43 and the fixed cutter head 51 are both located above the telescopic arm 4 .

[0036] When the lotus stem enters the retracting blade groove 411, as the retracting blade head 41 approaches the fixed blade head 51, the lotus stem will contact and abut against the stopper 43. In the process of cutting the lotus stem by the shearing cut formed by the fixed blade head 51 and the retracting blade head 41, the stopper 43 effectively stabilizes the lotus stem, thereby improving the efficiency of cutting the lotus stem. In addition, the separated lotus pod is squeezed by the stopper 43, so that the lotus pod is easier to fall into the collection frame 8.

[0037] Reference Figure 2 and Figure 3 Specifically, a U-shaped mounting frame 5 is fixed to the front end of the shell 3, and the bottom plate of the mounting frame 5 is fixed to the front end of the shell 3; the fixed cutter head 51 is fixed to the front end of the mounting frame 5; a driving arm 64 is arranged between the mounting frame 5 and the stopper 43; one end of the driving arm 64 is slidably mounted on the mounting frame 5, and the other end is fixedly connected to the stopper 43, and the sliding direction of the driving arm 64 is parallel to the sliding direction of the telescopic arm 4; a pivot 62 is vertically arranged and rotatably connected on the mounting frame 5, and a claw rod 61 is arranged on the pivot 62, and the claw rod 61 includes a hinge rod 611 and a swing rod 612; the outer end of the hinge rod 611 is rotatably arranged on the pivot 62, and the inner end is hinged to one end of the driving arm 64 that slides; one end of the swing rod 612 is fixedly connected to the outer end of the hinge rod 611, and the other end forms an embracing structure with the stop rod 42.

[0038] Under the action of the telescopic drive mechanism, the telescopic arm 4 retracts into the housing 3, and at this time, the stopper 43 and the stopper rod 42 gradually approach the fixed cutter head 51 and the mounting frame 5. At the same time, the stopper 43 also drives the driving arm 64, and the sliding end of the driving arm 64 drives the hinge rod 611 to rotate around the pivot 62; and the hinge rod 611 drives one end of the swing rod 612 to extend out of the mounting frame 5 and make the end close to the stopper rod 42. Therefore, the swing rod 612 and the stopper rod 42 move synchronously to form an embracing structure.

[0039] In the process of retracting the lotus stem, the swing rod 612 drives the lotus stem near the retracting blade head 41 to make it abut against the blocking rod 42; as the blocking rod 42 gradually approaches the fixed blade head 51, the swing rod 612 rotates around the pivot 62 at an increasing angle, and the distance between the swing rod 612 and the blocking rod 42 becomes smaller and smaller, and the lotus stem enters the retracting blade groove 411 along the length direction of the blocking rod 42 under the drive of the swing rod 612. After cutting off the lotus stem, the telescopic drive mechanism drives the telescopic arm 4 to extend out of the housing 3, and the swing rod 612 and the blocking rod 42 make synchronous reverse movements, and the swing rod 612 rotates around the pivot 62, and the blocking rod 42 is away from the fixed blade head 51; at this time, the swing rod 612 and the blocking rod 42 are respectively located on both sides of the retracting blade groove 411.

[0040] The embracing structure significantly expands the range of the lotus stems, and automatically gathers the lotus stems near the gathering blade head 41 and fixes them in the gathering blade groove 411 to facilitate cutting of the lotus stems. The structure effectively improves the accuracy of the lotus picking device in grabbing lotus stems within a certain range, effectively simplifies the steps of the picker operating the joystick 2, and avoids the picker being unable to accurately locate and cut the lotus stems due to the complex external environment and thus being unable to pick the lotus.

[0041] Reference Figure 2 and Figure 3 Specifically, a knife groove 431 is opened on the bottom of the stopper 43, and one side of the knife groove 431 passes through the side of the stopper 43 facing the shell 3, and the longitudinal section length of the knife groove 431 is greater than the length of the fixed knife head 51; the cross-sectional length of the knife groove 431 is greater than the width of the fixed knife head 51.

[0042] During the process of the fixed blade head 51 cutting the lotus stem, the distance between the stopper 43 and the fixed blade head 51 gradually decreases until the fixed blade head 51 cuts the lotus stem and enters the blade groove 431. The blade groove 431 is used to accommodate the fixed blade head 51, which helps the fixed blade head 51 to completely cut the lotus stem and improve the working efficiency of the fixed blade head 51.

[0043] Reference Figure 1 and Figure 3 Specifically, a receiving groove 432 is provided on the side of the stopper 43 facing the shell 3 along the length direction, and the lower end of the receiving groove 432 is connected to the knife groove 431. The receiving groove 432 is directly above the retracted knife groove 411, and the cross-section of the receiving groove 432 is arc-shaped.

[0044] When the lotus stem contacts the stopper 43, the lotus stem enters the receiving groove 432. The receiving groove 432 with an arc-shaped cross section is conducive to stabilizing the lotus stem, preventing the lotus stem from shaking, and improving the working efficiency of the fixed blade head 51.

[0045] Reference Figure 3 Specifically, one end of the driving arm 64 is slidably set on the mounting frame 5 through a sliding block 6 slidably set on the mounting frame 5, and a connecting rod 63 is set between the sliding block 6 and the inner end of the hinged rod 611; one end of the connecting rod 63 is hinged on the sliding block 6, and the other end is hinged on the inner end of the hinged rod 611.

[0046] When the telescopic arm 4 is retracted and extended from the housing 3, the stopper 43 drives the driving arm 64. One end of the driving arm 64 slides on the mounting frame 5 through the sliding block 6, and the sliding block 6 drives the connecting rod 63. The connecting rod 63 drives the hinged rod 611 to rotate around the pivot 62, and the hinged rod 611 also drives the swinging rod 612 to rotate around the pivot 62.

[0047] This structure effectively increases the rotation angle of the claw lever 61 around the pivot 62 .

[0048] Reference Figure 1 Specifically, the sliding mechanism is a joystick connecting sleeve 11, the joystick connecting sleeve 11 is hinged to the frame 1 through a universal joint, and a counterweight block 12 is arranged on the joystick connecting sleeve 11.

[0049] The counterweight 12 balances the weight on both sides of the frame 1, thereby making it easier for the picker to operate the joystick 2.

[0050] Reference Figure 1 Specifically, the telescopic drive mechanism is a cylinder 7, and the telescopic member is a piston rod of the cylinder 7; the cylinder body of the cylinder 7 is hinged on the inner wall of the housing 3, and the piston rod of the cylinder 7 is hinged on the end of the telescopic arm 4 extending into the housing 3. The air inlet end of the cylinder 7 is connected to the exhaust end of a compressor 72 arranged on the frame 1, and the compressor 72 is electrically connected to a power source.

[0051] When the piston rod of the cylinder 7 is extended, the telescopic arm 4 gradually moves away from the housing 3; when the piston rod of the cylinder 7 is shortened, the telescopic arm 4 gradually approaches the housing 3, and the fixed blade 51 performs the process of cutting the lotus stem.

[0052] Reference Figure 1 Specifically, a handle 21 is fixedly provided on the free end of the joystick 2, and a control switch 71 for controlling the extension and retraction of the piston rod of the cylinder 7 is provided on the handle 21. The control switch 71 is electrically connected to the cylinder 7 and the compressor 72 through a power supply. The handle 21 facilitates the picker to operate the joystick 2. In the process of operating the joystick 2, the extension and retraction of the piston rod of the cylinder 7 is controlled by the control switch 71, and the process of the fixed blade 51 cutting the lotus stem is carried out, thereby reducing labor intensity and improving work efficiency.

[0053] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
