Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coconut processing equipment, and in particular to a coconut clamping and conveying device based on a ratchet structure. BACKGROUND

[0002] Coconut is a tropical woody oil crop, which is composed of coconut skin, coconut shell, coconut meat and coconut juice. The coconut meat is rich in nutrients such as protein, calcium and glucose, and can be made into nutritious products such as dried coconut and coconut milk powder. During the processing of the harvested coconut, a clamping device is needed to fix the coconut shell.

[0003] The main problem of the existing coconut clamping device is that the existing clamping device only clamps the coconut in the horizontal direction. When the clamping device needs to be inverted to pour out the coconut meat from the coconut shell, it is very likely that the coconut shell will be separated from the clamping device together with the coconut meat. If the existing clamping device wants to avoid the situation of coconut shell falling off, it needs to increase the clamping force of the clamping device on the coconut shell, but too much increase in clamping force is easy to damage the coconut.

[0004] Therefore, a coconut clamping and conveying device based on a ratchet structure is needed to solve the above problems. SUMMARY

[0005] The present application provides a coconut clamping and conveying device based on a ratchet structure, which realizes stable clamping of the coconut through the elastic force of the tension spring and the one-way rotation property of the limiting shaft cylinder, improves the reliability of clamping the coconut under the premise of ensuring the integrity of the coconut.

[0008] At least two limiting shaft cylinders are arranged on each clamping seat, and each limiting shaft cylinder is rotatably installed on the corresponding clamping seat through a one-way ratchet mechanism.

[0010] As a preferred technical scheme, the bottom of the coconut cup is provided with a fixed middle plate, the fixed middle plate is fixedly connected with the bottom of the coconut cup through a center fixed rod, one end of each tensioning large arm away from the clamping seat is hingedly installed on the fixed middle plate, the movable frame is slidably installed on the fixed middle plate, and each tensioning spring is arranged between the movable frame and the fixed middle plate.

[0011] As a preferred technical scheme, the movable frame comprises a trigger bottom plate and a tensioning upper plate, the trigger bottom plate is arranged on the side of the fixed middle plate away from the coconut cup, the tensioning upper plate is arranged between the fixed middle plate and the coconut cup, the tensioning upper plate is slidably installed on the center fixed rod in the axial direction, one end of each tensioning small arm away from the tensioning large arm is hingedly installed on the tensioning upper plate, a plurality of connecting rods are slidably installed on the fixed middle plate, one end of each connecting rod is fixedly connected with the tensioning upper plate, and the other end of each connecting rod is fixedly connected with the trigger bottom plate.

[0012] As a preferred technical scheme, each connecting rod is sleeved with a tensioning spring, each tensioning spring is arranged between the trigger bottom plate and the fixed middle plate, one end of each tensioning spring is connected with the trigger bottom plate, and the other end of each tensioning spring is connected with the fixed middle plate.

[0013] As a preferred technical scheme, the side wall of the coconut cup is provided with at least three rectangular openings for passing through the clamping seat, and the number and position of the rectangular openings correspond to the number and position of the clamping seat.

[0014] As a preferred technical scheme, the outer wall of each limiting shaft cylinder is fixed with a plurality of strip-shaped convex ribs, and each strip-shaped convex rib extends in the axial direction of the limiting shaft cylinder.

[0015] As a preferred technical scheme, one end of each limiting shaft cylinder is rotatably installed on the corresponding mounting shaft through a first mounting bearing, and the other end of each limiting shaft cylinder is rotatably installed on the corresponding mounting shaft through a second mounting bearing.

[0016] The beneficial effects of the present application are as follows:

[0017] Since the coconut clamping and conveying device based on the ratchet structure comprises a coconut cup, a movable frame, a tension spring and a clamping seat, in the present application, the coconut clamping and conveying device clamps and fixes the coconut by using the elastic force of the clamping seat and the tension spring, and the clamping force of the clamping seat on the coconut shell changes with the size of the coconut. The volume of the coconut is proportional to the weight, the larger the volume of the coconut, the greater the angle of the clamping seat opening outward, and the greater the compression force of the tension spring, so the clamping force of the clamping seat on the coconut is also greater. Therefore, the coconut shell will not fall out of the coconut cup when the coconut cup is inverted, thereby improving the clamping reliability and stability of the clamping device while ensuring the integrity of the coconut.

[0018] Furthermore, the plurality of coconut cups in the present application can be used in combination, and the plurality of coconut cups are installed on the conveying device to drive the coconut to different processing stations. For example, the coconut cups are used to extract coconut meat from the coconut. Therefore, the coconut cups have two states of opening upward and opening downward during the movement of the coconut. When the top opening of the coconut cup is set upward, the coconut is placed in the coconut cup, the coconut cup drives the coconut to the processing station, the coconut meat inside the coconut is extracted, and the coconut meat is separated from the coconut shell. When the opening of the coconut cup is downward, the coconut cup is in an inverted state, the clamping seat continues to clamp and fix the coconut shell, and the coconut meat falls off, thereby automatically separating the coconut shell and the coconut meat.

[0019] Since at least two limiting shaft barrels are arranged on each clamping seat, and each limiting shaft barrel is rotatably installed on the corresponding clamping seat through a one-way ratchet mechanism, in the present application, the one-way ratchet mechanism allows the limiting shaft barrel to rotate in only one direction. When the coconut is placed in the coconut cup, the outer wall of the limiting shaft barrel contacts the outer wall of the coconut shell and rotates with the entry of the coconut. Conversely, when the coconut cup moves to an inverted state, the coconut shell has a downward movement out of the coconut cup under the action of gravity and applies a downward force to the limiting shaft barrel. However, the limiting shaft barrel cannot rotate under the action of the one-way ratchet mechanism, so that the limiting shaft barrel can limit and support the coconut shell. At the same time, the limiting shaft barrel is pressed against the outer wall of the coconut shell under the action of the elastic force of the tension spring, thereby realizing stable clamping of the coconut through the cooperative action of the elastic force of the tension spring and the one-way rotation property of the limiting shaft barrel, and avoiding the situation that the coconut shell falls with the coconut meat.

[0020] Since each clamping seat is hingedly connected with a tensioning large arm, and each tensioning large arm is hingedly connected with a tensioning small arm, in the application, the position of the movable frame is controlled to drive the tensioning small arms to rotate synchronously, and then the tensioning small arms drive the tensioning large arms and the clamping seats to rotate synchronously, thereby realizing the linkage action between the multiple clamping seats, so that the multiple clamping seats can clamp and release the coconut simultaneously, and further realizing the stable clamping and positioning of the coconut in multiple directions and multiple positions.

DETAILED DESCRIPTION

[0030] ​​With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0031] Figures 1-7 As shown, the coconut clamping and conveying device based on the ratchet structure comprises a coconut cup 2 for placing a coconut 1, a movable frame 3 is arranged below the coconut cup 2, the movable frame 3 is in sliding connection with the coconut cup 2, a tension spring 4 is installed between the movable frame 3 and the coconut cup 2, in the embodiment, the tension spring 4 can select different elastic coefficients according to the actual use scene requirements, so as to achieve the purpose of stably clamping the coconut 1 without damaging the coconut 1; the outer side of the coconut cup 2 is annularly and uniformly provided with at least three clamping seats 5, each clamping seat 5 is jointly hinged with the coconut cup 2 with a tension large arm 6, each tension large arm 6 is jointly hinged with the movable frame 3 with a tension small arm 7, in the embodiment, the position of the movable frame 3 is controlled to drive the tension small arm 7, the tension large arm 6 and the clamping seat 5 to perform synchronous action, so as to realize stable clamping and positioning of the coconut 1 in multiple directions and multiple positions.

[0032] Each clamping seat 5 is provided with at least two limiting shaft cylinders 13, each limiting shaft cylinder 13 is rotatably installed on the corresponding clamping seat 5 through a one-way ratchet mechanism, in the present application, the one-way ratchet mechanism enables the limiting shaft cylinder 13 to have the property of one-way rotation, when the coconut cup 2 is in an inverted state, the limiting shaft cylinder 13 cannot rotate under the action of the one-way ratchet mechanism, so as to realize reliable limiting of the coconut 1 and avoid the coconut shell 10 from falling off.

[0033] As shown in the figure, Figures 5-6 As shown, each one-way ratchet mechanism comprises an installation shaft 15, each installation shaft 15 is fixedly installed on the corresponding clamping seat 5, each limiting shaft cylinder 13 is rotatably installed on the installation shaft 15, the inner wall of each limiting shaft cylinder 13 is fixed with a plurality of one-way ratchet teeth 8 arranged in a ring shape, each installation shaft 15 is fixedly installed with a ratchet piece seat 14, the side wall of each ratchet piece seat 14 is fixed with a plurality of ratchet pieces 9, and each ratchet piece 9 is engaged with the one-way ratchet teeth 8 on the inner wall of the corresponding limiting shaft cylinder 13.

[0034] In the present application, when the coconut 1 enters the coconut cup 2, the outer wall of the coconut shell 10 pushes the limiting shaft cylinder 13 to rotate continuously, so that the ratchet 9 is continuously engaged with the one-way ratchet 8, thereby enabling the coconut 1 to smoothly enter the coconut cup 2. Conversely, when the coconut cup 2 is inverted, the coconut shell 10 has a tendency to fall out of the coconut cup 2. At this time, the ratchet 9 is inserted into the one-way ratchet 8, so that the limiting shaft cylinder 13 cannot rotate under the force applied by the coconut shell 10. Therefore, the outer wall of the limiting shaft cylinder 13 firmly abuts against the outer wall of the coconut shell 10, thereby preventing the coconut shell 10 from falling out of the coconut cup 2.

[0035] As shown in the drawings, Figures 1-3 As shown in the drawings, the bottom of the coconut cup 2 is provided with a fixed middle plate 17, and the fixed middle plate 17 is fixedly connected to the bottom of the coconut cup 2 through a center fixed rod 18. The end of each tensioning large arm 6 away from the clamping seat 5 is hingedly installed on the fixed middle plate 17, and the movable frame 3 is slidingly installed on the fixed middle plate 17. Each tensioning spring 4 is arranged between the movable frame 3 and the fixed middle plate 17.

[0036] Furthermore, the movable frame 3 comprises a trigger bottom plate 19 and a tensioning upper plate 20. The trigger bottom plate 19 is arranged on the side of the fixed middle plate 17 away from the coconut cup 2, and the tensioning upper plate 20 is arranged between the fixed middle plate 17 and the coconut cup 2. The tensioning upper plate 20 is slidingly installed on the center fixed rod 18 in the axial direction. The end of each tensioning small arm 7 away from the tensioning large arm 6 is hingedly installed on the tensioning upper plate 20. A plurality of connecting rods 21 are slidingly installed on the fixed middle plate 17. One end of each connecting rod 21 is fixedly connected to the tensioning upper plate 20, and the other end of each connecting rod 21 is fixedly connected to the trigger bottom plate 19.

[0037] In the present embodiment, the connection mode between the two ends of the center fixed rod 18 and the coconut cup 2 and the fixed middle plate 17 is not limited to welding, and other modes such as bolt connection that can achieve the purpose of fixed connection are also available. Similarly, the connection mode between the two ends of the connecting rod 21 and the trigger bottom plate 19 and the tensioning upper plate 20 is not limited. The tensioning large arm 6 and the tensioning small arm 7 are made of high-strength steel material, which can ensure the stability of clamping.

[0038] Each connecting rod 21 is sleeved with a tensioning spring 4. Each tensioning spring 4 is arranged between the trigger bottom plate 19 and the fixed middle plate 17. One end of each tensioning spring 4 is connected to the trigger bottom plate 19, and the other end of each tensioning spring 4 is connected to the fixed middle plate 17.

[0039] In addition, the side wall of the coconut cup 2 is provided with at least three rectangular openings 22 for clamping seats 5, the number and position of the rectangular openings 22 correspond to the number and position of the clamping seats 5, in this embodiment, each rectangular opening 22 should be larger than the clamping seat 5, to ensure that the clamping seat 5 and the limiting shaft cylinder 13 smoothly enter the inside of the coconut cup 2 to clamp and fix the coconut 1, and the length and size of the limiting shaft cylinder 13 can be adjusted according to actual conditions to meet the needs of different use scenarios.

[0040] As Figures 5-7 As shown, the outer wall of each limiting shaft cylinder 13 is fixed with a plurality of strip-shaped convex ribs 23, each strip-shaped convex rib 23 extends along the axial direction of the limiting shaft cylinder 13, in this embodiment, the strip-shaped convex rib 23 increases the friction between the limiting shaft cylinder 13 and the outer wall of the coconut shell 10, thereby improving the stability of clamping.

[0041] One end of each limiting shaft cylinder 13 is rotatably mounted on the corresponding mounting shaft 15 through a first mounting bearing 12, and the other end of each limiting shaft cylinder 13 is rotatably mounted on the corresponding mounting shaft 15 through a second mounting bearing 16.

[0042] Taking the use of the present application in the coconut meat digging work as an example, the working process of clamping and conveying the coconut 1 by the present application is as follows:

[0043] In the first step, when the coconut cup 2 is in the state of opening upward, the coconut 1 is pressed downward into the coconut cup 2, in this process, the outer shell of the coconut 1 pushes the clamping seat 5 and simultaneously rotates outward, and the outer wall of the limiting shaft cylinder 13 contacts the outer shell of the coconut 1, and the limiting shaft cylinder 13 continuously rotates in one direction around the mounting shaft 15;

[0044] In the second step, after the coconut 1 is completely put into the coconut cup 2, the digging tool is inserted between the coconut shell 10 and the coconut meat 11, and rotates one circle to separate the coconut meat 11 from the coconut shell 10;

[0045] In the third step, the coconut cup 2 drives the coconut 1 after the digging work to move, and drives the coconut 1 to be conveyed to the inverted state of opening downward, and the coconut meat 11 in the coconut 1 falls out of the coconut shell 10 and falls into the coconut meat collecting container located below;

[0046] In the third step, then a certain pressure is given to the trigger bottom plate 19, the trigger bottom plate 19 drives the tensioning upper plate 20 to move towards the coconut cup 2, the movement of the tensioning upper plate 20 causes the tensioning small arm 7 to rotate, the tensioning small arm 7 drives the tensioning large arm 6 to rotate, and the clamping seat 5 simultaneously moves outward, the limiting shaft cylinder 13 separates from the coconut shell 10, thereby realizing the relaxation of the coconut shell 10, at this time, the coconut shell 10 falls under the action of gravity and falls into the coconut shell collecting container located below;

[0047] The fourth step, after the coconut cup 2 moves and rotates back to the state of the opening facing upward, the above steps are repeated to perform the coconut meat 11 extraction work on another coconut 1.

[0048] In summary, the present application provides a coconut clamping and conveying device based on a ratchet structure, which realizes stable clamping of the coconut 1 through the elastic force of the tension spring 4 and the one-way rotation property of the limiting shaft cylinder 13, thereby improving the reliability of clamping the coconut 1 under the premise of ensuring the integrity of the coconut 1.
